Description

Reagent library and automatic analysis device

Technical Field

The utility model relates to a reagent library and an automatic analysis device.

Background technique

The automatic analyzer is a device that optically measures the mixed solution of the sample sampled from the subject and the reagent for analyzing each test item and generates analytical data for biochemical test items, immunological test items, hemagglutination test items, etc. The automatic analyzer stores the reagents for testing in the reagent warehouse, transports the sample container containing the standard sample or the test sample through the conveyor belt, and measures the mixed solution of the reagent and the standard sample or the mixed solution of the reagent and the test sample through the reaction unit. If the opening of the reagent container is left open for a long time, it is easy to cause the evaporation and deterioration of the reagent, so the opening of the reagent container needs to be closed by a cover structure.

In the prior art, there is a method of opening the opening of the reagent container by making the swing arm of the reagent container cover contact with the opening and closing block in the reagent storehouse. However, in this structure, the opening direction of the cover is vertical, and a large space needs to be reserved between the opening of the reagent container and the reagent storehouse cover. In addition, in the working state, the reagent container continuously rotates around the center of the reagent storehouse, and the reagent container has to complete the action of opening and closing the cover every time it passes through the opening and closing block, which will lead to unnecessary increase in friction, and the wear powder generated may circulate in the reagent storehouse and enter the reagent container to contaminate the reagent.

Utility Model Content

The utility model aims to provide a reagent storehouse and an automatic analysis device which can avoid unnecessary repeated opening and closing of an opening and closing cover of a reagent container.

In order to achieve the above-mentioned purpose, the reagent library of the embodiment of the utility model includes: a reagent library main body; a reagent container, which is accommodated in the reagent library main body and can rotate along the center of the reagent library main body, the reagent container includes a container main body and an opening and closing cover that can slide in a horizontal direction to close or open the reagent in the container main body; and an opening and closing mechanism, which is arranged on the rotation path of the reagent container and causes the opening and closing cover to slide in a horizontal direction by turning on and off the power of an electromagnet.

An automatic analyzer according to another embodiment includes the above-mentioned reagent library.

The utility model controls the on and off of the electromagnet so that the cover of the reagent container is opened only when needed, thereby avoiding unnecessary repeated opening and closing of the cover of the reagent container, preventing the reagent from deteriorating, and ensuring the accuracy of the measurement result.

(First Embodiment)

FIG1 is a schematic structural diagram showing an automatic analysis device 1 of the present invention.

Next, a structure of an automatic analysis device 1 of the present invention is exemplarily described with reference to FIG. 1 .

The automatic analyzer 1 is a device that optically measures a mixed solution of a sample collected from a subject and a reagent for analyzing each test item for biochemical test items, immunological test items, blood coagulation test items, etc., and generates analysis data.

As shown in FIG. 1 , the automatic analyzer 1 includes a conveyor 2 , a sample dispensing arm 21 , a reagent reservoir 3 , a reagent dispensing arm 81 , a reaction unit 4 , a stirring arm 41 , a measuring unit 5 , a cleaning unit 6 , and a control system 7 .

The conveyor 2 is provided so as to extend in the X-axis direction (front-rear direction), and the conveyor 2 movably holds a sample rack containing sample containers.

An annular rotating track is provided in the reagent storage 3, and reagent containers containing reagents are placed on the rotating track. The reagent containers are arranged at equal intervals along the annular rotating track of the reagent storage 3. The reagent storage 3 maintains the annular rotating track in a rotatable manner. The reagent storage 3 keeps the reagent containers cold.

An annular rotating track is provided in the reaction section 4, and reaction containers containing a mixed solution of a sample and a reagent are placed on the rotating track. The reaction containers are arranged at equal intervals along the annular rotating track of the reaction section 4. The reaction section 4 holds the annular rotating track in a rotatable manner.

The sample dispensing arm 21 is arranged to be freely rotatable between the reaction section 4 and the conveyor belt 2 around its own axis parallel to the Y axis. A sample dispensing probe is provided at one end of the sample dispensing arm 21. The sample dispensing probe rotates along with the rotation of the sample dispensing arm 21. The rotation path of the sample dispensing probe intersects with the rotation tracks of the sample container on the conveyor belt 2 and the reaction container in the reaction section 4, respectively, and the intersection of the rotation path of the sample dispensing probe and the rotation tracks of the sample container on the conveyor belt 2 and the reaction container in the reaction section 4 becomes the sample suction position and the sample discharge position.

The sample dispensing arm 21 samples the sample, and the sample dispensing arm 21 transfers the sample between the sample container of the conveyor belt 2 and the reaction container of the reaction section 4. The sample dispensing arm 21 can be raised and lowered in the longitudinal direction (Y-axis direction) so that the sample dispensing probe moves in the longitudinal direction between the sample suction position and the sample discharge position. The sample dispensing probe sucks the standard sample in the sample container located at the sample suction position, and dispenses it into the reaction container located at the sample discharge position in the reaction section 4. In addition, the sample dispensing probe sucks the test sample in the sample container located at the sample suction position, and dispenses it into the reaction container stopped at the sample discharge position in the reaction section 4.

The reagent dispensing arm 81 is arranged to be freely rotatable between the reagent reservoir 3 and the reaction section 4 around its own axis parallel to the Y axis. The reagent dispensing arm 81 has a reagent dispensing probe. The reagent dispensing probe rotates along with the rotation of the reagent dispensing arm 81. The rotation path of the reagent dispensing probe intersects with the rotation track of the reagent container in the reagent reservoir 3 and the rotation track of the reaction container in the reaction section 4, respectively, and the intersection of the rotation path of the reagent dispensing probe and the rotation track of the reagent container in the reagent reservoir 3 and the rotation track of the reaction container in the reaction section 4 becomes the reagent suction position and the reagent discharge position.

The reagent dispensing arm 81 transfers the reagent between the reagent container in the reagent storage 3 and the reaction container in the reaction section 4. The reagent dispensing arm 81 can be raised and lowered in the longitudinal direction (Y-axis direction) so that the reagent dispensing probe moves in the longitudinal direction between the reagent suction position and the reagent discharge position. The reagent dispensing probe sucks the reagent in the reagent container at the reagent suction position and dispenses it into the reaction container at the reagent discharge position in the reaction section 4.

After the sample dispensing probe discharges the standard sample or the test sample and the reagent dispensing probe discharges the reagent, the stirring arm 41 stirs the mixed solution of the standard sample and the reagent or the mixed solution of the test sample and the reagent in the reaction container stopped at the stirring position in the reaction unit 4 .

The measuring unit 5 performs optical measurement on the mixed solution in the reaction container in the reaction unit 4. The measuring unit 5 irradiates light on the mixed solution in each reaction container in the reaction unit 4, detects the light transmitted through the mixed solution in the reaction container in the reaction unit 4, and generates standard data and test data represented by absorbance and the amount of change in absorbance, for example, based on the obtained detection signal.

The cleaning section 6 cleans the reaction container stopped at the cleaning position in the reaction section 4 that has completed the measurement by the measuring section 5. The cleaning section 6 includes a waste liquid nozzle, a cleaning unit, and a drying nozzle. The cleaning section 6 sucks the mixed liquid as waste liquid in the reaction container in the reaction section 4 through the waste liquid nozzle. The cleaning section 6 uses the cleaning unit to discharge the cleaning liquid into the reaction container from which the waste liquid has been sucked to clean the reaction container. The cleaning section 6 supplies dry air to the cleaned reaction container through the drying nozzle, thereby drying the reaction container.

The control system 7 is electrically connected to the above-mentioned components and controls the above-mentioned components.

Next, a structure of a reagent library 3a in the prior art is exemplarily described with reference to FIG. 2 .

FIG. 2 is a schematic diagram showing the structure of a reagent library 3 a in the prior art.

In the prior art, as shown in Figure 2, a reagent container 31a is accommodated in a reagent storehouse 3a, and the reagent container 31a can rotate around the center of the reagent storehouse 3a. A cover 32a is arranged on the opening of the reagent container 31a in a detachable manner. A swing arm 33a extending toward the outer wall of the reagent storehouse 3a is formed on the cover 32a. An opening and closing block 34a located at the reagent dispensing position is fixedly arranged on the outer wall of the reagent storehouse 3a, and the opening and closing block 34a is located on the rotation path of the reagent container 31a. Under working conditions, since the reagent container 31a continuously rotates in the reagent storehouse 3a, the swing arm 33a of the reagent container 31a rotated to the opening and closing block 34a will contact the guide surface of the opening and closing block 34a, and then the opening and closing of the cover 32a when dispensing the reagent is guided by the guide surface of the opening and closing block 34a.

However, in the prior art, the reagent container 31a continuously rotates in the reagent reservoir 3a, and each time the cover 32a passes the guide surface of the opening and closing block 34a, it must complete an opening and closing action, resulting in unnecessary increased friction. The abrasive powder generated thereby may circulate in the reagent reservoir 3a and enter the reagent container 31a to contaminate the reagent.

Next, the structure of the reagent storage 3 in the first embodiment for avoiding unnecessary repeated opening and closing of the opening and closing cover of the reagent container will be described with reference to FIG. 3 .

FIG. 3 is a schematic diagram showing a part of the reagent storage 3 according to the first embodiment.

As shown in FIG. 3 , in this embodiment, the reagent storage 3 includes a reagent storage body 30 , a reagent container 31 , and an opening and closing mechanism 32 .

The reagent container 31 is accommodated in the reagent storage body 30 , and is used to hold the reagent. The plurality of reagent containers 31 are sequentially arranged around the center of the reagent storage body 30 , and the reagent containers 31 can rotate along the center of the reagent storage body 30 .

The reagent container 31 includes a container body 33 and an opening and closing cover 34. The container body 33 is a bottle-shaped structure, and the container body 33 contains the reagent. The opening and closing cover 34 is arranged above the container body 33, and the opening and closing cover 34 can slide in the horizontal direction (i.e., the radial direction of the reagent storage body 30), and the opening and closing cover 34 closes or opens the reagent in the container body 33 by sliding in the horizontal direction. The opening and closing cover 34 is provided with a magnetic body that can be attracted by the magnetic force of the electromagnet.

The opening and closing mechanism 32 is provided on the rotation path of the reagent container 31 and is located at the reagent dispensing position of the reagent storage 3. The opening and closing mechanism 32 slides the opening and closing cover 34 in the horizontal direction at a predetermined timing by turning the electromagnet on and off.

When the reagent container 31 rotates to the reagent dispensing position and needs to be collected, the opening and closing mechanism 32 causes the electromagnet to energize and attract the magnetic body on the opening and closing cover 34, so that the opening and closing cover 34 slides to open the reagent in the container body 33. When the collection of medicine is completed, the opening and closing mechanism 32 releases the magnetic body on the opening and closing cover 34 by turning off the power of the electromagnet, so that the opening and closing cover 34 slides to seal the reagent in the container body 33. In this embodiment, the opening and closing cover 34 of the reagent container 31 is opened only when collecting medicine, and the opening and closing cover 34 is not operated at other non-collecting times (for example, when the reagent container 31 only temporarily stays at the collecting position or passes through the collecting position). In this way, unnecessary repeated friction between the opening and closing cover 34 of the reagent container 31 and the container body 33 is avoided, the degradation of the reagent is prevented, and the accuracy of the measurement result is ensured.

Next, the specific structure of the reagent container 31 of the reagent storage 3 in the first embodiment will be described with reference to FIG. 4 , FIG. 5 , and FIG. 6 .

FIG. 4 is a schematic diagram showing a part of the reagent container 31 in the reagent storage 3 according to the first embodiment.

FIG. 5 is another partial schematic diagram showing the reagent container 31 in the reagent storage 3 according to the first embodiment.

FIG. 6 is a schematic diagram showing the structure of a cover 341 of a reagent container 31 in the reagent storage 3 according to the first embodiment.

As shown in FIGS. 4 and 5 , the container body 33 of the reagent container 31 includes a receiving portion 331 , a shoulder portion 332 , and an opening portion 333 .

The receiving portion 331 is a bottle-shaped member with an opening at the top. A shoulder 332 constituting a horizontal top surface of the receiving portion 331 is formed on the receiving portion 331 . An opening 333 is formed on the shoulder 332 . The opening 333 is used to absorb or dispense the reagent in the receiving portion 331 .

The opening and closing cover 34 includes a cover seat 341 , a cover plate 342 and a force applying portion 343 .

The cover seat 341 is used to fix the opening and closing cover 34 on the shoulder 332 of the container body 33, and the cover seat 341 is roughly a rectangular body. The cover plate 342 is arranged on the cover seat 341, and the cover plate 342 is generally a component extending in the horizontal direction. The cover plate 342 includes a part extending in the horizontal direction (the X-axis direction in FIG. 4) and a part extending in the longitudinal direction (the Y-axis direction in FIG. 4). The cover plate 342 can slide on the cover seat 341 in the horizontal direction. The cover plate 342 can move between a position (the position in FIG. 4) of closing the opening portion 333 and a position (the position in FIG. 5) of exposing the opening portion 333 by sliding in the horizontal direction on the cover seat 341. The force applying part 343 is arranged between the cover seat 341 and the cover plate 342, and one end of the force applying part 343 is connected to the cover seat 341, and the other end is connected to a part of the cover plate 342 extending in the longitudinal direction. The force applying portion 343 applies force to the cover plate 342 so that the cover plate 342 can return to the position of closing the opening portion 333 after sliding. Specifically, in this embodiment, a tension spring is used as an example of the force applying portion 343, and the tension spring always applies force in the force applying direction (X-axis direction) so that a portion of the cover plate 342 extending in the longitudinal direction approaches the cover seat 341.

In this embodiment, a portion of the cover plate 342 extending in the horizontal direction and a portion extending in the longitudinal direction may be made of magnetic metal materials, and the entire cover plate 342 may serve as the magnetic body of the opening and closing cover 34. In addition, only a portion of the cover plate 342 extending in the longitudinal direction may be made of magnetic metal materials, and a portion of the cover plate 342 may serve as the magnetic body of the opening and closing cover 34. In other words, the magnetic body on the opening and closing cover 34 constitutes at least a portion of the cover plate 342. Using the entire cover plate 342 as a magnetic body may reduce the difficulty and cost of manufacturing. Using a portion of the cover plate 342 as a magnetic body may reduce the overall weight of the cover plate 342 and may also enhance the corrosion resistance of the cover plate 342.

As shown in FIG6 , a flange portion 3412 is formed at the edge of the top of the cover seat 341. A hollow recess 3411 is formed at the bottom of the cover seat 341. The shape of the recess 3411 matches the shape of the shoulder 332. The recess 3411 is used to be sleeved on the shoulder 332. The surfaces where the recess 3411 and the shoulder 332 abut against each other are provided with an adhesive, and the cover seat 341 is fixed to the shoulder 332 through the adhesive.

As shown in Figures 4 and 5, a slide groove portion 3421 is formed on the edge of the portion of the cover plate 342 extending in the horizontal direction. The shapes of the slide groove portion 3421 and the flange portion 3412 match each other. The flange portion 3412 is embedded in the slide groove portion 3421. The slide groove portion 3421 and the flange portion 3412 cooperate with each other to enable the cover plate 342 to slide horizontally relative to the cover seat 341.

In addition, although the above description takes the example of forming a flange portion 3412 on the cover seat 341 and forming a slide groove portion 3421 on the cover plate 342, it is also possible to form a slide groove portion 3421 on the cover seat 341 and form a flange portion 3412 on the cover plate 342. That is, as long as one of the flange portion 3412 or the slide groove portion 3421 is formed on the top of the cover seat 341, the other of the flange portion 3412 or the slide groove portion 3421 is formed on the cover plate 342.

As shown in FIG. 4 and FIG. 5 , the opening and closing mechanism 32 includes an electromagnet 321 and a fixing seat 322 .

In the present embodiment, since the tension spring is used as the force applying part 343 for explanation, it is necessary to set the electromagnet 321 at one end in the +X direction of the opening and closing cover 34 along the force applying direction of the force applying part 343 (i.e., the X-axis direction in FIG. 4 ). In addition, the electromagnet 321 can also be set at one end in the -X direction of the opening and closing cover 34 along the force applying direction of the force applying part 343. In this case, it is only necessary to change the force applying part 343 to a compression spring. The fixing seat 322 is used to fix the electromagnet 321, and the fixing seat 322 can be set on the inner wall of the reagent storage body 30 of the reagent storage 3. In addition, in order to prevent the magnetism of the electromagnet 321 from interfering with other components, the fixing seat 322 can also be set at the bottom of the cover of the reagent storage 3.

In this embodiment, as shown in FIG. 5 , the electromagnet 321 generates a magnetic force to attract the magnetic body on the opening and closing cover 34 when powered on. The electromagnet 321 attracts the magnetic body on the opening and closing cover 34 to slide the cover plate 342 relative to the cover seat 341 along the +X direction, and the opening 333 is opened.

As shown in FIG. 4 , the electromagnet 321 loses its magnetic force when the power is turned off and releases the magnetic body on the opening and closing cover 34 . The force applying part 343 pulls the cover plate 342 back toward the cover seat 341 . The cover plate 342 slides along the −X direction and the opening 333 is closed.

In addition, as shown in FIG. 4 and FIG. 5 , in this embodiment, although the rectangular flat plate-shaped cover plate 342 is used as an example for explanation, the cover plate 342 may be any shape other than a rectangle, as long as it can satisfy the requirement that the opening 333 can be closed after the electromagnet 321 is powered off and the cover plate 342 is reset, and the opening 333 can be opened after the electromagnet 321 is powered on and the cover plate 342 slides.

Next, a control process of the electromagnet 321 of the reagent storage 3 of the automatic analyzer 1 in the first embodiment will be described with reference to FIG. 7 .

FIG. 7 is a control flow chart showing the control system 7 of the automatic analyzer 1 in the first embodiment.

In this embodiment, the control system 7 of the automatic analyzer 1 connects the opening and closing mechanism 32 to the reagent library main body 30 and the reagent dispensing arm 81 of the automatic analyzer 1. The control system sends an on-off signal to the electromagnet 321 of the opening and closing mechanism 32 based on the action information of the reagent dispensing arm 81 and/or the rotation state information of the reagent container 31, so that the opening and closing cover 34 of the reagent container 31 is opened only when collecting medicine.

The automatic analyzer 1 includes a sensor that detects the action information of the reagent dispensing arm 81 or the rotation state information of the reagent container 31 and transmits it to the control system 7. The action information of the reagent dispensing arm 81 can be information when the reagent dispensing arm 81 performs a descending action. The rotation state information of the reagent container 31 can be information when the reagent container 31 stops rotating and the reagent storage 3 is in a non-standby state. The rotation state information of the reagent container 31 can also be information when the opening 333 of the reagent container 31 is shielded by the reagent dispensing probe of the reagent dispensing arm 81.

In Fig. 7, n represents the number of sensors, and each sensor is used to detect the action information of the reagent dispensing arm 81 or the rotation state information of the reagent container 31. If each sensor does not detect the corresponding action, it will feedback 0 to the upper level, and if it detects the corresponding action, it will feedback 1 to the upper level. S1, S2, ..., Sn represent the signal values fed back by each sensor.

As shown in FIG7 , when the automatic analysis device 1 starts working, first, in step P1, the system is initialized. At this time, the electromagnet 321 is not energized. Under the action of the force-applying part 343, the opening 333 is shielded by the cover plate 342. At this time, the signal values S1=S2=...=Sn=0 fed back by each sensor, and the process proceeds to step P2. In step P2, the control system 7 reads the signal values S1, S2,..., Sn fed back by the sensors in sequence, and the process proceeds to step P3. In step P3, the control system 7 determines whether each sensor has detected a corresponding action. If at least one sensor detects a corresponding action, then S1+S2+...+Sn≠0, indicating that a reagent container 31 has rotated to the reagent dispensing position, and the reagent needs to be collected, and the process proceeds to step P4. In step P3, if all sensors do not detect the corresponding information, then S1+S2+...+Sn=0, indicating that the reagent does not need to be collected, and the process returns to step P2. In step P4, the control system 7 controls the electromagnet 321 to be energized. Under the magnetic attraction of the electromagnet 321, the opening and closing cover 34 is opened, the opening 333 is exposed, and the reagent container 31 located at the reagent dispensing position can smoothly collect medicine, and the process proceeds to step P5. In step P5, the control system 7 determines whether the electromagnet 321 is energized for a specified time t. When the energization time does not reach the specified time t, it means that the collection of medicine has not been completed, and the process returns to step P4. In step P5, if the energization time reaches the specified time t, it means that the collection of medicine has been completed, and the process proceeds to step P6. In step P6, the control system 7 de-energizes the electromagnet 321. Since the electromagnet 321 loses its magnetic force, under the action of the force applying part 343, the opening 333 is shielded by the reset cover plate 342, and the process proceeds to step P7. In step P7, the control system 7 determines whether the automatic analysis device 1 has stopped working. If the automatic analysis device 1 has not stopped working, the control system 7 returns to step P1 and sets the signal values fed back by each sensor to 0, that is, S1=S2=...=Sn=0, and the above process continues. In step P7, if the automatic analysis device 1 has stopped working, the entire process ends.

According to this embodiment, the opening and closing cover of the reagent container is opened only when needed by controlling the on and off power of the electromagnet, thereby avoiding unnecessary repeated opening and closing of the opening and closing cover of the reagent container, preventing the degradation of the reagent, and ensuring the accuracy of the measurement result.

Figure 8 is a schematic diagram of the structure of the opening and closing cover 34 of the reagent container 31 in the reagent library 3 involved in the first embodiment, Figure 8(a) is a schematic diagram when the cover plate 342 of the opening and closing cover 34 is configured as a step shape, and Figure 8(b) is a schematic diagram when the cover plate 342 of the opening and closing cover 34 is configured as a curve.

As shown in FIG8 , in this variation, in order to adapt to the internal structure of the reagent storage body 30 or the different shapes of the container body 33, the cover plate 342 may not be a flat plate. As shown in FIG8( a ), the cover plate 342 may be configured in a stepped shape. As shown in FIG8( b ), the cover plate 342 may be configured in a curved shape.

(Variation 2)

FIG. 9 is a schematic diagram showing another structure of the opening and closing cover 34 of the reagent container 31 in the reagent storage 3 according to the first embodiment.

In order to improve the maintenance efficiency of the cover plate 342 and reduce the manufacturing difficulty, the magnetic body may not be used as a part of the cover plate 342, but as a transition piece 3422 disposed on the cover plate 342. As shown in FIG9, in this modified example, the transition piece 3422 is connected to a portion of the cover plate 342 extending in the longitudinal direction. When the electromagnet 321 is powered on, the transition piece 3422 is attracted to drive the cover plate 342 to slide, and when the electromagnet 321 is powered off, the cover plate 342 is reset under the tension of the force applying portion 343.

(Variant 3)

FIG. 10 is a schematic diagram showing a structure in which the opening and closing cover 34 and the container body 33 of the reagent container 31 in the reagent storage 3 according to the first embodiment are fixedly connected.

In order to facilitate the removal of the cover seat 341 fixed on the shoulder 332 of the container body 33 during cleaning or maintenance, the cover seat 341 may not be attached to the shoulder 332. As shown in FIG10 , in this modified example, a hole portion 351 is formed on the recess 3411 of the cover seat 341, and a boss portion 352 is formed on the shoulder 332 of the container body 33. The hole portion 351 and the boss portion 352 form an interference fit, thereby achieving the fixation of the cover seat 341 on the shoulder 332 in a detachable manner. In addition, the boss portion 352 may be formed on the cover seat 341, and the hole portion 351 may be formed on the shoulder 332. In other words, as long as one of the hole portion 351 or the boss portion 352 is formed on the recess 3411, and the other of the hole portion 351 or the boss portion 352 is formed on the shoulder 332, it is sufficient.

(Variant 4)

FIG. 11 is a schematic diagram showing another structure in which the opening and closing cover 34 and the container body 33 of the reagent container 31 in the reagent storage 3 according to the first embodiment are fixedly connected.

In order to facilitate the removal of the cover seat 341 fixed on the shoulder 332 of the container body 33 during cleaning or maintenance, the cover seat 341 may not be pasted on the shoulder 332. As shown in FIG11 , in this modified example, a claw portion 361 is formed on the recess 3411 of the cover seat 341, and a slot portion 362 is formed on the shoulder 332 of the container body 33. The claw portion 361 and the slot portion 362 match each other, thereby achieving the fixation of the cover seat 341 on the shoulder 332 in a detachable manner. In addition, the slot portion 362 may be formed on the cover seat 341, and the claw portion 361 may be formed on the shoulder 332. In other words, as long as one of the claw portion 361 or the slot portion 362 is formed on the recess 3411, and the other of the claw portion 361 or the slot portion 362 is formed on the shoulder 332, it is sufficient.

(Variant 5)

FIG. 12 is a schematic diagram showing another structure in which the opening and closing cover 34 and the container body 33 of the reagent container 31 in the reagent storage 3 according to the first embodiment are fixedly connected.

In order to facilitate the removal of the cover seat 341 fixed on the shoulder 332 of the container body 33 during cleaning or maintenance, the cover seat 341 may not be attached to the shoulder 332. As shown in FIG12 , in this modified example, a clamping portion 37 is formed at the bottom of the cover seat 341, and the specific structure of the clamping portion 37 is a dovetail clamp type that can be opened and closed by pressing. By pressing the clamping portion 37, the portion where the cover seat 341 abuts against the shoulder 332 is enlarged, so that the cover seat 341 can be clamped on the shoulder 332. Conversely, by pressing the clamping portion 37, the cover seat 341 can be removed from the shoulder 332 without much effort.
