  Since the conventional container can be easily opened by pushing down the push button, even an infant can easily open the container. Therefore, the contents stored in the container may be used wastefully, and the stored contents may be chemicals. There is also a risk of physical danger.

  In general, it is difficult for an infant or the like having a weak force to perform a push-pull back operation in a horizontal front-rear direction rather than a downward push-down operation. In the present invention, focusing on this point, the container is provided with a lock plate that is slid horizontally in the front-rear direction, and the cover plate is kept closed by sliding back of the lock plate. It is provided so that it can be opened from the lid, and it is necessary to add a push-down operation to the operation based on the operation, or to perform a double operation of the operation, or perform the push-down operation in the lock plate advance state. By making the lid open only when it is done, or by urging the lid toward the lid opening direction, it is difficult for infants to open, making it easy for adults to use and making the container easy to use It is intended.

As a first means, a concave fitting portion is formed in the front surface of the lid body 11 which is pivotally connected to the rear portion of the container body 1 so that the upper surface opening 3 of the container body can be opened and closed. A lock plate 41 is provided on the container body so that it can slide in the front-rear direction.
When the lock plate 41 is pushed backward and slid in the closed state of the lid, the rear end portion of the lock plate is fitted into the concave fitting portion so that the lid cannot be opened. By sliding 41 forward and sliding, the rear end of the lock plate was extracted from the fitting recess, and the lid could be opened.

In addition, an inclined surface 21 is formed on both sides downward and rearward.

As a third means, the first or second means is provided, and a swing with a slide path is pivotally attached to the container main body portion in front of the lid body so as to freely swing back and forth. The movable plate 31 is pivotally attached, and the lock plate 41 is penetrated into the sliding path.
Further, the lower surface of the front end of the swing plate 31 is engaged with the upper surface of the locking projection 16 attached to the front surface of the lid 11, and the plate spring 35 is suspended from the swing plate portion in front of the pivotally attached portion so as to suspend the container body. It is in contact with part of the top surface of
Even in the unlocked state, it is impossible to open the lid by engaging the locking projection 16 with the lower surface of the front end portion of the swing plate, and when the front portion of the swing plate 31 is pushed down against the elasticity of the leaf spring, The front surface of the rocking plate 31 is moved forward and upward from the locking projection 16 by rocking about the pivot portion, so that the lid can be opened.

  As a fourth means, the third means is provided, and the sliding paths are provided side by side so that the lock plate 41 penetrates into the respective sliding paths.

  As a fifth means, the lock plate includes the third or fourth means, and a leg 48 is provided on the lower surface of the front portion of the lock plate 41, and a high portion and a low portion are formed on the upper surface of the container body. When retreating, the lower surface of the leg 48 comes into contact with the upper surface of the high part and cannot be lowered.When the lock plate is advanced, the leg 48 moves upwards of the lower part, and only at this position, the front part of the swing plate 31 is pushed. It can be lowered.

  As a sixth means, the first, second, third, fourth or fifth means is provided, and the lid body 11 is biased in the opening direction.

  According to the first aspect of the present invention, it is difficult to perform the lid opening operation as compared with the conventional example described above, and the lid opening by an infant or the like can be prevented.

  According to the second aspect, the lid closing operation is facilitated.

  By making it like Claim 3, 4 or 5, the case of Claim 3 rather than the case of Claim 1 and the case of Claim 4 rather than the case of Claim 3 for the infant etc. Further, in the case of claim 5, the case of claim 5 can be made more difficult to open than the case of claim 4, and for an adult, it is easy to open the cover because it is only necessary to know the operation sequence with instructions.

  By making it like Claim 6, the convenience of a container can be improved.

  Referring to the drawings, reference numeral 1 denotes a container body, which has an opening 3 at the center of the top wall 2, and a lower end surface of the peripheral wall 4 is closed by a bottom lid 5. A first concave portion 6 having a narrow front portion is drilled forward from an intermediate portion in the left-right direction of the rear portion of the top wall of the container main body (right side in the figure), and the opening 3 is provided at the center of the first concave portion. A second recess 7 is formed, a third recess 8 for lowering a leg, which will be described later, is formed at the front of the first recess, and a fourth recess 9 is formed at the rear of the first recess.

  A portion excluding the front portion of the first recess 6 is closed with a lid 11. As shown in FIG. 2, the lid has pins 12 projecting from the left and right sides of the rear part to the left and right sides, and these pins are fitted into shaft holes provided on the left and right sides of the first recess. The seal wall 13 is suspended by being fitted to the inner wall surface of the recess 7, and the front wall 15 having a horizontally long hole 14 as a recessed fitting portion for fitting the rear end of the lock plate is suspended from the front end of the lid. . The locking projections 16 are projected forward from the left and right sides of the horizontally long hole.

  In the illustrated example, the locking plate 18 protruded from the left and right intermediate portion of the rear edge of the lid body via the hinge 17 is formed in a vertically inverted concave shape between the locking plate and the lower surface of the rear portion of the lid body. A state in which the connecting plate portion of the plate spring 19 provided on the side is sandwiched, the locking plate base portion is straddled by the parallel leg-like plate portion 20 of the plate spring, and the leg-like plate portion 20 is protruded into the fourth recess 9 When the lid body 11 is turned from the opened state to the closing direction around the pin 12 as described above, the leaf spring 19 is shown in FIG. 1 so as to be elastically bent.

  A swing plate 31 is pivotally attached to the front portion of the lid 11 as shown in FIGS. The rocking plate has a pin 32 projecting from both left and right sides of the rear end portion and is fitted into a shaft hole drilled in the inner wall of the first recess 6, and as shown in FIGS. 1, 3, and 4, A guide plate 33 having an L-shaped cross-section for holding a lock plate, which will be described later, is suspended from the lower surface with the lower sides 33a facing the left and right pairs facing each other. Further, a leaf spring 35 protrudes downward and forward from the lower surface of the swinging plate portion between the pair of left and right guide plates, and is in contact with the upper surface of the first recess 6 bottom plate. The front end edge of the swing plate 31 extends from the upper end of the third recess 8 to the rear, and the rear end is in contact with the upper surface of the locking protrusion 16 provided on the front face of the cover body when the cover body is closed. The lid shall be prevented.

  A lock plate 41 shown in FIG. 4 is sandwiched between the pair of left and right guide plates 33 of the swing plate so as to be slidable in the front-rear direction. That is, each of the pair of guide plates forms a sliding path of the lock plate, and thus the sliding path can be replaced with a sliding through hole.

  The lock plates are also a pair of left and right, and these two lock plates are integrally connected by a flexible piece 42 at the intermediate portion in the front-rear direction. Each lock plate has a middle portion of the main plate 43 that is long in the front-rear direction as a ring portion as an elastic compression portion 44, and a finger-hanging plate 46 in front of the main plate 43 via a protruding plate 45 extending laterally from the front-rear direction intermediate portion. It is provided in parallel with the portion, and protrudes forward from the front end of the main plate, and the finger-hanging protrusion 47 is erected from the front end edge. The overhanging plate 45 protrudes outward from the side surface of the main plate 43 on the side not having the flexible piece 42. The lock plate is mounted by placing the finger-hanging plate 46 between the hanging sides 33b of the pair of guide plates described above and placing the finger-hanging plate 46 on the lower side 33a of the guide plate. The lock plate is slidable in the front-rear direction independently on the left and right sides. When only one of the lock plates moves forward and the other is located rearward, the flexible piece 42 is deformed and kept in this state.

  1 and 2 show a state in which both lock plates are pushed backward, in which the rear end of the main plate of the lock plate is inserted into the oblong hole 14 in the front wall 15 of the lid, In this state, the lid cannot be opened, and in this state, the leg 48 attached to the lower surface of the front portion of the lock plate 41 contacts the bottom surface of the first recess as shown in FIG. There is nothing.

  When the lock plate 41 is advanced from the above state as shown in FIG. 3, the rear portion of the main plate 43 is extracted from the laterally long hole 14, and the leg 48 is moved above the third recess 8. The locked state is released by removing the rear part of the main plate from the inside of the horizontally long hole. At this time, however, the locking projection 16 on the front wall of the lid is still in contact with the lower surface of the rear end of the swing plate 31. I can't open the lid. In order to open the lid, the finger hooking projection 47 at the front end of the lock plate is further pushed downward from the position shown in FIG. The front portion of the lock plate 41 attached to the swing plate 31 by the depression is lowered together with the front portion of the swing plate around the pin 32, and the rear end edge of the swing plate is moved upward and forward by the swing. The lid 11 that has been released from the locking projection 16 and has been biased in the direction of opening the lid opens.

  The lid is normally closed with the lock plate advanced as shown in FIG. Since the rocking plate 31 is immediately elastically restored by the repulsion of the leaf spring 35 after the front part is pushed down, the locking projection 16 on the front wall of the lid body is pushed back by the push of the front part of the lid body. Although it touches the edge, it moves over the rear end of the swinging plate by forced depression, and by pushing the lock plate 41 backward from this state, the rear part of the main plate 43 of the lock plate enters the laterally long hole 14, and the leg 48 is It rides on the bottom surface of the first recess as shown in FIG.

  When the lid front part is pushed down with the lock plate 41 retracted, the rear end of the lock member protrudes rearward from the rear end of the swing plate 31 as shown in FIG. 15 is in contact with the upper surface of the rear end of the lock plate 41, but one or both of the front surface of the lower surface of the front wall and the rear end surface of the lock plate are inclined to the lower rear side 21 so that the lid front wall 15 Will push the lock plate forward, and the ring portion of the lock plate will be compressed, the lock plate portion behind the ring portion will be pushed forward by the lid front wall 15 and the horizontally long hole 14 will move to the rear end of the lock plate. When the position is lowered to the position, the elastic compression portion 44 formed by the ring portion is elastically restored, and the rear end of the lock plate is fitted into the laterally long hole 14.

  In the above embodiment, the leaf spring 19 that urges the lid body 11 in the opening direction and the swing plate 31 that prevents the lid from being unlocked are provided, but one or both of these are provided. It may be removed, or a single lock plate 41 may be provided. When the rocking plate 31 is removed and only one lock plate 41 is used, the lock plate is only the main plate 43, and both sides of the main plate can be swung into the lateral grooves in the front-rear direction provided on the front left and right inner walls of the first recess. It is conceivable to fit them.

  All the above-described members are formed of a synthetic resin material.
