  In the chemical liquid supply device of Patent Document 1, an aerosol product containing a chemical liquid and a propellant and an application member that supplies the chemical liquid to the body and an application member that cools the body are connected by a tube. Can be stored in a pocket or the like. Therefore, it suffices to attach only the imparting member to the part to be imparted by the body, and it can be used easily. However, care must be taken not to bend the tube along the way. In addition, it is difficult to use a hard tube that does not break. The body cooling device of Patent Document 2 has the same problem.

The nozzle of Patent Document 3 has an advantage that it can be jetted softly because a large number of nozzle holes are provided in the middle of the nozzle, but it is difficult to apply when applied to the body, particularly the user's own body, such as around the neck. Since the injection member of patent document 4 interposes the channel | path divided into right and left between a stem and an injection hole, it can be made to eject by bypassing the obstacle in the middle. When a nozzle hole is provided on the inner surface of this bypass path, a chemical can be applied to the finger, but it is difficult to apply it to a wide range such as around the neck or shoulder. An object of the present invention is to provide a simple injection device for a body that can be easily worn, is easy to use, and can easily apply a chemical solution around the neck and shoulder.

  The injection device for a body of the present invention is flexible and is connected to a nozzle having a tube having an injection hole on a side surface in an annular shape, and to allow the contents to be injected into the nozzle between both ends of the nozzle. (1). Such an injection device for the body is preferably such that the annularly curved nozzle is 100 to 1500 mm and can pass through the user's head, neck, shoulder, arm, wrist, leg or waist ( Claim 2). Further, it is preferable that a connecting tool having a T-shaped passage is connected to the aerosol product, and two-way passages of the connecting tool are connected between both ends of the nozzle. Furthermore, it is preferable that the small-sized injection product includes a switching mechanism for switching between an injection enabled state and an injection blocking state.

  According to a second aspect of the body ejection device of the present invention, there is provided an annular suspension strap that is flexible and can pass through the user's head, neck, shoulder, arm, wrist, leg, or waist, and its It consists of the small injection product connected with the suspension string, The said small injection product is provided with the switching mechanism for switching to the injection possible state and an injection prevention state (Claim 5).

  In the case of a body spray device provided with the switching mechanism, it is preferable that the switching is performed by rotating a knob provided on the small spray product (Claim 6). Furthermore, in any of the above body-use injection devices, the small-sized injection product preferably has a weight of 50 g or less, a diameter of 25 mm or less, and a height of 100 mm or less (Claim 7). In any of the above body spray devices, the small spray product is preferably a small aerosol product.

  The body injection device according to the present invention (Claim 1) employs a nozzle that is flexible and has an annularly curved tube having a nozzle on its side surface, and a small injection product between both ends of the nozzle. Since the nozzles are connected to each other, the small injection product itself can be attached to the body by suspending or holding the nozzle on the body. In addition, since the small injection product can be integrated with the nozzle, it is not necessary to separately prepare a tube for connecting the small injection product and the nozzle, which is easy to use. The content ejected from the small-sized jetting product passes through the internal cavity of the tube and ejects from a nozzle formed on the side surface. Therefore, the contents of the small spray product can be sprayed widely and gently around the body part surrounded by the nozzle.

  In such a body injection device, the annularly connected nozzle is 100 to 1500 mm and can pass through the user's head, neck, shoulder, arm, wrist, leg or waist. In the case (Claim 2), it can be suspended in close contact with the body, which is more convenient.

  When a connector having a T-shaped passage is connected to the small-sized injection product, and two-way passages of the connector are connected between both ends of the nozzle (Claim 3), The contents are injected into the nozzle from both ends thereof, and are ejected to the outside from a nozzle formed in the middle. Therefore, the contents ejected from the small-sized jetting product travel in the reverse direction in the nozzle and meet in the vicinity of the center of the nozzle. And since it is ejected to the outside from the nozzle hole in the middle, the internal pressure is gradually reduced and the resistance is reduced, reaching the middle part of the nozzle and exhibiting the effect.

  When the small injection product has a switching mechanism for switching between an injection enabled state and an injection blocking state (Claim 4), the small injection product is mounted around the neck and shoulder when switched to the injection blocking state. Even if a small jet product shakes violently, no chemicals are accidentally jetted. And when a user intends to inject, it should just inject after switching operation to an injection possible state.

  According to a second aspect (Claim 5) of the injection device for body of the present invention, a small injection product is applied to the body by hanging an annular suspension strap on the head, neck, shoulder, arm, wrist, leg or waist. Can be installed. And since the small injection product is provided with the switching mechanism for switching to the injection possible state and the injection inhibition state, even when the user performs intense exercises, it does not inject accidentally. In the case of spraying, the hanging strap can be removed, or while being suspended, the switching mechanism of the small spray product can be operated to spray the body. Therefore, it is easy to use.

  When the switching is performed by rotating the knob provided on the small injection product (Claim 6), the switching operation is performed for the first time by picking the knob and the other part with both hands and adding a twisting operation. Can do. Therefore, safety students are high.

  When the small injection product has a weight of 50 g or less, a diameter of 25 mm or less, and a height of 100 mm or less (Claim 7), since it is particularly lightweight and small, it is a burden on the user even if it is suspended from the neck or the like. do not become. In any of the above body-use injection devices, when the small injection product is a small aerosol product (claim 8), the injection and stop operations are simple. Furthermore, it is easy to feed the medicine into the nozzle due to the pressure of the propellant.

  The injection apparatus 10 shown in FIG. 1 is comprised in the form of what is called a pendant from the cyclic | annular nozzle 11 lowered | hung to a neck, and the small aerosol product 12 suspended by the nozzle 11. FIG. The nozzle 11 bends the tube 13 made of synthetic resin in an annular shape, and both ends thereof are connected to the push button 14 so as to face each other. The tube 13 has a hardness that does not collapse the inner cavity when it is bent and a flexibility that can be bent with a certain radius of curvature. It may have elasticity that returns to a straight line when the bending force is loosened. The curved shape may be maintained without returning.

The material of the tube 13 is polyethylene, polypropylene, nylon, etc., the outer diameter is about 2 to 10 mm, and the inner diameter is about 1 to 7 mm. The nozzle holes 15 are formed in the tube at intervals of 1/2 to 1/10 of the tube length. The direction of the nozzle hole 15 is determined according to the application. In the embodiment of FIG. 1, in order to spray a refreshing agent around the user's neck, the nozzle hole 15 is formed on the curved inner surface side. The nozzle holes 15 may be provided at equal intervals, or the intervals may be adjusted according to the purpose, for example, to inject evenly. Furthermore, the number of nozzle holes per length can be changed or the nozzle holes can be omitted depending on the site. The size of the nozzle hole is preferably 0.1 to 3 mm. The size of the nozzle holes 15 may be the same, and the injection amount from each nozzle hole can be adjusted, such as gradually increasing from the end of the tube 13 to the center.

  As shown in FIG. 2, the push button 14 is formed with a substantially T-shaped passage 16, and the stem 18 of the small aerosol product 12 is fitted into the stem fitting hole 17 a communicating with the downward passage 17. Yes. The small aerosol product 12 is supported and suspended by the fitting friction between the stem fitting hole 17a and the stem 18. However, other fixing means such as screws may be employed. In the lateral passages 19, 19 extending to the left and right, a male screw portion provided at one end of a connector for tube piping (a joint, see reference numeral 20 in FIG. 1) is screwed, and the tube 13 is connected to the other end of the connector. The end of the is inserted and airtightly connected. However, as shown in FIG. 2, the end of the tube 13 may be directly fixed to the push button 14. Reference numeral 21 denotes a collet that holds the end of the tube 13 in an airtight manner. Other types of tube connectors can be used. If one end or both ends of the tube 13 can be detachably connected to the push button 14, the tube 13 can be easily mounted around the waist and can be easily mounted without touching the hair.

  The small aerosol product 12 can be used in various configurations and sizes as long as it is small and light, but preferably has a weight of 50 g or less, a diameter of 25 mm or less, and a height of 100 mm or less. In FIG. 2, the small aerosol product 12 includes a pressure-resistant bottomed cylindrical main body 22, a valve 23 for closing the upper end opening of the main body, a cap 24 for fixing the valve to the main body 22, and the inside of the main body 22. And an aerosol composition filled in.

  The valve 23 is interposed between the housing 25, the stem 18 movably accommodated in the housing, a spring 26 that constantly biases the stem upward, and the cap 24 and the housing 25. And a gasket 27 for closing the holes. The cap 24 is placed on the upper portion of the main body 22 and the vicinity of the lower end is crimped (clamped) to an annular small diameter portion 28 provided on the upper portion of the main body. Thereby, the valve 23 is fixed to the main body 22.

  Inside the small aerosol product 12 is a stock solution such as a refreshing agent, a cooling agent, a repellent, a deodorant, a cologne, and a liquefied gas such as liquefied petroleum gas, dimethyl ether or a mixed gas thereof, or nitrogen, carbon dioxide, air, etc. The propellant made of the compressed gas is filled. In addition to spraying, the nozzle 11 can eject only liquid, only foam, or a mixture of these.

  The pendant type injection device 10 configured as described above can be carried around by hanging around the neck as shown in FIG. 3A, for example. And when spraying, the bottom part of the main body 22 of the small aerosol product 12 and the head part of the push button 14 are picked with a finger, force is applied to an axial direction, and the push button 14 is pushed down. Alternatively, the main body 22 is pushed up. 2 is pushed in, the valve 23 is opened, and the aerosol composition is ejected from the upper end opening of the stem 18. Therefore, the sprayed aerosol composition enters the nozzle 11 via the T-shaped passage 16 in the push button 14 and the left and right connectors 20. In the curved nozzle 11, the aerosol composition proceeds in the opposite direction from both ends toward the center portion, and is ejected to the outside from the nozzle hole 15 formed in the middle until the middle portion meets (see arrow P). . In the embodiment of FIG. 3 a, since the nozzle hole 15 is formed on the inner side of the nozzle 11, it is injected around the neck 30. The nozzle 15 is usually a small hole. However, it can also be a slit.

  FIG. 3 b shows an embodiment in which a pair of left and right injection devices 10, 10 are provided on the inner surface and seam portion of the shirt. In this embodiment, the nozzle 11 of each injection device 10 is attached to the inner surface of the shirt U so as to surround the armhole. The nozzle hole formed in the nozzle 11 faces outward so as to be sprayed onto the human body. The small aerosol product 12 is substantially the same as in the case of the injection device 10 of FIGS. The nozzle 11 is sewed inside the shirt U or sewed outside. When sewing on the inside, the shirt U is provided with a slit for inserting a hand. When sewing on the outside, the shirt U is provided with a hole through which the push button 14 for connecting the nozzle 11 and the small aerosol product 12 is passed, or a hole through which a tube for connecting the nozzle 11 and the small aerosol product 12 is passed.

  In this embodiment, the nozzle 11 is sewed on the shirt U, the small aerosol product 12 is detachable from the push button 14, and the small aerosol product 12 is always removed from the push button 14 and small when sprayed. The aerosol product 12 may be attached to the push button 14. In that case, it is preferable to fix to the shirt U the part to which the small aerosol product 12 of the push button 14 is mounted. In addition to the shirt U, the nozzle 11 can be sewn on a thing to be worn on the body such as a suit, tie, hat, trousers, supporter, wristband, hair band, or a hook-and-loop fastener such as Velcro (registered trademark). It may be attached detachably.

  The injection device 30 shown in FIG. 4 is configured such that the small aerosol product 12 and the push button 14 are relatively movable in the axial direction and relatively rotatable about the own axis. A cylindrical shoulder cover 32 is provided on the shoulder 31 of the main body 22, and a lower portion 33 of the push button 14 is fitted to the inner surface of the shoulder cover 32 so as to be movable up and down and rotatable. Further, as shown in FIG. 5b, a cutout groove 34 is formed in the shoulder cover 32, and a protrusion 35 that engages with the cutout groove 14 is provided on the lower surface side of the push button 14. When the push button 14 is not pushed, the height of the protrusion 35 is such that the lower end of the protrusion 35 engages with the upper end of the shoulder cover 32 and the like as shown in FIG. The dimensions are not possible.

  When the user simply hangs from the neck or shoulder, the injection device 30 configured as described above is located at a position where the lower end of the projection 35 engages with the upper end of the shoulder cover 32 as shown in FIG. Keep rotating. Accordingly, even if an axial force is applied to the push button 14 or the main body 22 by mistake, the contents are not ejected. When the user wants to perform the injection operation, as shown in FIG. 5B, the main body 22 or the push button 14 is rotated about 90 degrees around its own axis, and the position of the protrusion 35 is adjusted to the position of the notch groove 34. In this state, when the user operates the push button 14 or the main body 22 in the axial direction, the protrusion 35 can enter the notch groove 34, so that the push operation can be performed. Therefore, by changing the relative rotation position of the push button 14 and the main body 22, it is possible to switch between the injection enabled state and the injection blocked state. A resistance means such as a frictional resistance is provided between the push button 14 and the upper end of the shoulder cover 32 so that the push button 14 does not rotate freely.

  In addition, in the injection apparatus 30 of FIG.4, FIG.5a, FIG.5b, it may replace with the nozzle consisting of a tube, and may employ | adopt the hanging string 36. FIG. In that case, the nozzle tip 37 is provided on the push button 14. In addition to spraying, a liquid or foam can be ejected. The hanging strap 36 may be connected to the push button 14 or may be connected to the main body 22, a case containing the main body, or the shoulder cover 32. As the hanging string 36, a string formed by twisting natural or synthetic fibers can be used. Thus, since the hanging strap 32 is flexible, the injection device 30 in which the hanging strap 36 is attached to the small aerosol product 12 does not have a sense of incongruity around the neck and the shoulder. Further, by engaging the push button 14 with the upper end of the shoulder cover 32, erroneous injection can be prevented and safety is high.

  In the injection device 30 that can be switched between the injection enabled state and the injection blocked state by the twisting operation of FIGS. 4, 5 a, and 5 b, a nozzle formed of a tube having a number of injection holes as in the injection device 10 of FIG. 1. 11 can be adopted. In that case, the nozzle tip 37 is unnecessary. However, both can be provided. Further, instead of the shoulder cover 32, a bottomed cylindrical case that accommodates the entire main body 22 may be used.

  An injection device 40 shown in FIG. 6 includes a bottomed cylindrical case 41 that accommodates the small aerosol product 12 and a cap 42 that is rotatably and vertically movable on the upper end of the case 41. A helical cam groove 43 shown in FIG. 7 is formed on the inner surface of the cap 42, and a protrusion 44 that slides in the cam groove 43 is formed on the outer peripheral surface of the case 41. Further, an upper lock groove 45 extends axially upward from the upper end of the cam groove 43 of the cap 42, and a lower lock groove 46 extends axially downward from the lower end of the cam groove 43. A top surface or a transition piece 47 that engages with the push button 14 is formed on the upper surface of the cap 42, and a notch 48 or an opening is formed on the peripheral surface of the cap 42 so as not to interfere with the injection. A hanging strap 32 is connected to the cap 42.

  In the injection device 40, when the case 41 and the cap 42 are picked with both hands and rotated somewhat, the protrusion 44 of the case 41 slides obliquely upward in the cam groove 43. Accordingly, the cap 42 moves relatively in the direction of deeply fitting the case 41. As a result, the cross piece 47 pushes the push button 14 against the upward biasing force applied to the stem, and the injection starts from the nozzle tip 37. When the cap 42 is sufficiently rotated and the protrusion 44 enters the upper lock groove 45, the state is locked, and the injection continues until it is released. When the case 41 and the cap 42 are given relative rotation in opposite directions, the injection stops. At this time, if the protrusion 44 is engaged with the lower lock groove 46, no injection is performed even if an axial force is applied by mistake. Such cam grooves 43 and protrusions 44 act as a switching mechanism for switching between the injectable state and the injectable state.

  In the injection device 50 shown in FIG. 8, the push button 14 is configured to be rotatable with respect to the main body 22. In this case, the push button 14 may be rotatable relative to the stem 18 and the stem 18 may be rotatable relative to the valve housing. As shown in FIG. 9, the shoulder cover 51 is provided with a shielding wall 52 that blocks injection. Further, the shoulder cover 51 is formed with a projection 53 that interferes with the lower end of the push button 14 to prevent vertical movement, and the lower surface of the push button 14 avoids interference with the projection 53 at a specific rotation position. A cutout 54 that allows movement is formed. Further, flat surfaces 55 or recesses are formed at two locations on the peripheral surface of the push button 14 so as to be easily picked.

  When the push button 14 is rotated so that the nozzle tip 17 faces the shielding wall 52 (injection prevention state), the lower end of the push button 14 is projected on the shoulder cover 51 even when the push button 14 is pressed. Can not be pushed down by interfering with 53. When the push button 14 is pushed in a state where the nozzle tip 17 is rotated to a position where it is removed from the shielding wall 52 (injectable state), the notch 54 at the lower end of the push button 14 comes to the position of the protrusion 53, so that it can be pushed down. Can spray the spray.

  In the injection device 50 shown in FIG. 8, the shoulder cover 51 can be configured to be rotatable instead of the configuration in which the push button 14 is rotatable. In addition, only some parts including the blocking wall 52 can be configured to rotate with respect to the shoulder cover 51. Although only one end of the hanging strap 32 is connected to the shoulder cover 51, both ends can be connected as in the case of FIG. It is preferable that one end or both ends of the hanging strap are detachably connected to the spray product. In each of the above embodiments, a small aerosol product is used. However, instead of the small aerosol product, other types of small injection products such as a small pump-type injection product can be adopted.
