Description

The present invention relates to a container with a lid, and more particularly to a technique which can store medicines, detergents and the like and can be easily opened, but is still suitable for use in a child proof packaging.

Conventionally, when storing and storing items such as medicines that are dangerous for children, when they are placed in a freely openable box, they are generally kept in a high place out of the reach of children or in a drawer with a lock. Met. However, it is common sense in handling that a structure that can be opened and closed easily when needed is desired.
In general, children often put anything in their mouth, and if medicines are placed within the reach of children, it is possible that a child may accidentally swallow or swallow medicines if the box is openable. Was very high. A description of a child proof for preventing such a situation, particularly a description of a medicine, is described in Patent Document 1, and an example of a container having a function as a child proof is described in Patent Document 2.

Also, recently, a water-soluble film detergent, that is, a cleaning composition encapsulated with a water-soluble film that dissolves during use, is known as described in Patent Document 3. Since the appearance of the water-soluble film detergent is similar to that of confectionery such as jelly, children may accidentally swallow it. Ingestion and aspiration of infants have a great social impact because they may have a great influence on their health. As a preventive measure, it may be possible to store it in a container with a lock mechanism for sale, but it is a daily use such as detergent, so if the opening and closing is too complicated, the user will not use it. There is a possibility that it will end up.

In addition to water-soluble film detergents, toiletry products that require means for preventing accidental ingestion, such as toilet detergents and bath cleaning tablets, are increasing.
At the same time, these toiletry products are required to be capable of exhibiting stacked products and to have space-saving properties during transportation, predetermined strength, and constant moisture resistance.

However, if the structure is overly complicated in order to prioritize safety, the cost will be too high, and even if the cost burden for an expensive drug can be tolerated, the cost burden for cheaper products such as detergents will not be tolerated. Not done.
However, if the structure is too simple and inexpensive, a curious child may open the container while hitting or rolling various places.

Therefore, it has a structure that cannot be easily opened by children, and is a container for storage and storage that is relatively easy for adults to open and can be supplied inexpensively. The demand for containers was increasing.

The present invention has been made in view of the above circumstances, and it is possible to provide a child-proof at a low cost while surely realizing the child-proof, display of loaded products, space saving during transportation, and a container with a lid having a predetermined strength. It aims to achieve the purpose of being able to provide.

By providing two or more locking portions that lock the lid body and the frame body in the closed state with a predetermined distance that is a child proof, specifically, the distance between the locking portions is increased. , By setting the size of the child's hand to be child-proof so that it cannot be operated by a child with a small hand size, at least two locking parts cannot be unlocked at the same time. Since a large adult can easily release the lock at the same time, it is possible to realize a child proof with a simple structure and to avoid inconvenience for daily use by an adult.

In the container with a lid of the present invention, in the locking portion, the locking of the locking portion is released by the deformation of the respective locking portions in directions toward each other, so that at least two locking portions simultaneously. In order to release the locking, it is necessary to deform these locking parts at the same time in a direction in which they approach each other. Even if the locking is released, the locking is not released at the other locking portion at the same time, so that the closed state of the lid can be maintained and the child proof can be realized.

In the container with lid of the present invention, when the locking portion has a locking piece extending in a direction orthogonal to the rotation axis of the lid body in the hinge, the locking of the locking portion is released. The direction in which the locking piece is deformed is orthogonal to the rotation axis of the lid in the hinge, so that the locking pieces are pinched so as to be close to each other, and the lid is rotated around the rotation axis of the hinge. That is, the child proof can be realized because the locking cannot be released unless the operations in the two directions are performed at the same time.
At the same time, the locking pieces are provided so as to project from the front surface of the lidded container toward the front side, or the locking pieces are provided so as to project upward from the side surface of the lidded container, thereby bringing the locking pieces close to each other. In the unlocking operation, the operation can be performed even when the operator's claw does not abut the side surface of the container body or the like, so that an operator with a long claw can easily perform the opening operation.

In the container with a lid of the present invention, as the two locking portions, the locking pieces having locking projections are provided on the lid body, and the locking recesses to which the locking projections are locked are the frame body. Since the integrated frame body and the lid body are transported, the integrated frame body and the lid body can be stacked without interfering with the locking pieces when the integrated frame body and the lid body are transported, thereby saving space. .. Further, when the frame body is provided with a hole corresponding to a hooking portion connected to a container body described later, a through hole can be provided as a locking recess.

In the container with a lid of the present invention, the two locking portions are provided at positions corresponding to the other side facing the one side, so that when the lid body is opened, the operator can use two hands on one side with one hand. The stopper is released by pressing the stoppers so that they come close to each other at the same time, and the lock is released, and while holding the lock released, the hand holding the lock is moved to rotate the lid around the hinge. This makes it easy to open the lid.

In the container with lid of the present invention, the two locking portions are provided on the two sides adjacent to the one side, respectively, so that in the opening operation of the lid, the operator can operate the two sides of the container with one hand. The lock is released by pressing and deforming two certain locking parts at the same time so as to be close to each other, and the locking part is provided to rotate the lid around the hinge while maintaining the unlocking. The lid can be easily opened by moving the hand.

In the container with lid of the present invention, the frame body is connected to the flange of the container body extending to the opening surface so as to cover the flange, and at a position separated from the frame edge portion. By providing the connecting portion that connects with the flange, even when a force acts in a direction to force the frame body away from the container body, a deforming force similarly acts on the edge portion of the frame body and the connecting portion. Therefore, even if the frame body is largely deformed and the edge portion of the frame body is deformed in the direction away from the flange, the connection at the connection portion is not released, and the frame body and the lid are not disconnected. It is possible to prevent the body from coming off the container body and releasing the closure of the container.

In the container with a lid of the present invention, the connecting portion is a hooking portion provided at a substantially central position in the width direction of the opening surface of the frame, so that the frame edge is forced from the flange of the container body. Even when a force acts in the direction of separating, the deforming force acting on the connection part can be reduced more than the edge part of the frame body, and the connection of the engaging part is not released by the deformation of the frame body. It is possible to prevent the closure of the container from being released by the body or lid coming off the basic body.

Is provided with a flange 26 having a predetermined width, and the flange 26 is circumferentially provided so as to project outward in the horizontal direction from the upper ends of the front surface 22, the rear surface 23, the right side surface 24, and the left side surface 25 which are flush with each other. There is.

As shown in FIGS. 1 to 6, the frame 30 is connected to the container body 20 so as to cover the opening surface contour of the container body 20, and specifically covers the entire circumference of the flange 26 from the upper side. As described above, the frame surface portion 31 having a substantially rectangular contour extending in the horizontal plane, the outer peripheral surface portion 32 provided at the outer peripheral position of the frame surface portion 31 in a substantially vertical direction, and the inner peripheral side of the frame surface portion 31 provided in a substantially vertical direction. And an inner peripheral surface portion 33.
The frame body 30 is rotatably connected to the lid body 50 by a hinge 40 provided at a horizontal position in the left-right direction at a position corresponding to one side on the rear side of the opening of the container body 20.

As shown in FIGS. 1 to 6, in the hinge 40, in the wide connecting piece 41 extending in the direction from the frame body 30 to the lid body 50, the thickness of the straight line portion in the left-right direction passing through a certain point is extremely small. It is set and can be bent from this portion due to the flexibility of the constituent material.

As shown in FIGS. 1 to 6, the lid body 50 is configured to open and close the opening of the container body 20 so as to correspond to the frame surface portion 51 having a shape corresponding to the frame surface portion 31 and the inner peripheral surface portion 33. Has an inner peripheral surface portion 53 and a lid surface portion 54 extending inside the inner peripheral surface portion 53.
The lid body 50 is rotatably connected to the frame body 30 and the container body 20 integrally engaged with the frame body 30 with the hinge 40 as a rotation axis.
In the closed state of the lid body 50, the frame surface portion 51 circulates the opening edge portion in a substantially horizontal state, and the inner peripheral surface portion 53 is connected downward to the inner peripheral end thereof.
At the outer peripheral end of the frame surface portion 51, a closing ridge 52 is provided so as to protrude downward when the lid 50 is closed and is in parallel with the outer peripheral surface portion 32 and is in contact with the upper surface of the frame surface portion 31.

As shown in FIGS. 1 to 6, the lid surface portion 54 is substantially parallel to the bottom surface 21, the flange 26, the frame surface portion 51, and the frame surface portion 31 in the closed state of the lid body 50, and becomes the opening of the container body 20. The entire area of the opening of the frame body 30 is covered and closed. The lid surface portion 54 and the inner peripheral surface portion 53 are set to have substantially the same contour shape as the bottom surface 21 in plan view.
As shown in FIGS. 1 to 6, the lid surface portion 54 is parallel to the frame surface portion 51 by the inner peripheral surface portion 53 and is located on the bottom surface 21 side (lower side) of the flange 26. The height dimension of the blocking ridge 52 is set. Accordingly, by inserting the bottom surface 21 side of the container body 20 into the concave portion formed by the lid surface portion 54 and the inner peripheral surface portion 53, it is possible to stably load the plurality of lidded containers 10.

As shown in FIGS. 1 to 6, the lid 50 has a central portion on one side of the opening of the container body 20 on the front surface 22 side, which is parallel to the outer peripheral surface portion 32 and outside in the closed state of the lid 50. The front surface portion 55 is provided so as to overlap with.
The lateral dimension of the front surface portion 55 is set smaller than that of the hinge 40. Further, the horizontal dimension of the hinge 40 is set to be equal to or slightly smaller than the horizontal dimension at the upper end of the rear surface 23. Thereby, as will be described later, the rigidity of the hinge 40, the lid body 50, and the frame body 30 can be maintained so as to maintain the deformation resistance of the lid body 50 for exhibiting the child proof.

As shown in FIGS. 1 to 6, the frame surface portion 31 is positioned such that the center portion in the width direction of the lower side surface (rear surface) 31 a thereof contacts the upper surface of the flange 26 over the entire circumference, and the flange 26 is fixed to the frame surface portion 31. The outer peripheral surface portion 32 and the inner peripheral surface portion 33 are connected by a connecting portion described later so as to be fixed in a space surrounded by the outer peripheral surface portion 32 and the inner peripheral surface portion 33.

As shown in FIGS. 1 to 6, the outer peripheral surface portion 32 is provided on the entire outer periphery of the frame surface portion 31 with substantially the same height dimension (width dimension).
As shown in FIGS. 1 to 6, the upper end 32 a of the outer peripheral surface portion 32 is higher than the heights of the blocking ridges 52 and the frame surface portion 51 so that the lid body 50 is hidden in a side view, and the frame surface portion 31. Is erected so as to protrude from the upper surface of the. Further, in the closed state of the lid body 50, the outer peripheral end portion of the frame surface portion 51 and the closing ridge 52 are both arranged so as to be close to the upper end 32 a of the outer peripheral surface portion 32, and the frame body 30 and the lid body 50. Since the fingers are not applied to the joint, it is normally impossible to release the locking portions 60, 70 except for the operation.

As shown in FIGS. 1 to 6, a stack portion 34 is provided around the lower end 32b of the outer peripheral surface portion 32 so as to extend further outward and downward via a horizontal flange 34a.
As shown in FIGS. 1 to 6, the stack portion 34 has a front surface portion 55 and locking portions 60 and 70 that interfere with each other when the integrated lid body 50 and frame body 30 are stacked and stored/transported. In order not to do so, it is arranged only near the positions corresponding to the right side surface 24 and the left side surface 25 so as to avoid the front surface portion 55 and the hinge 40.
As shown in FIGS. 1 to 6, the upper end 32 a of the outer peripheral surface portion 32 is also provided so as to avoid the front surface portion 55 and the hinge 40 as in the stack portion 34, but the rear surface 23, the right side surface 24, and the left side surface 25. It is located near the position corresponding to and.

As shown in FIGS. 1 to 6, the frame surface portion 31 has a lower side surface 31 a that abuts the flange 26 so as to be substantially parallel to the outer peripheral surface portion 32 at a position slightly outside the center position in the width direction. A connecting projection 35 serving as a connecting portion is provided so as to project downward.

As shown in FIGS. 1 to 6, the connecting protrusion 35 has a width of the frame surface portion 31 so as to come into contact with the outer peripheral end surface 26 a of the flange 26 when the frame body 30 and the container body 20 are connected. Directional position is set.
The connecting projection 35 has a hook convex portion 35a for fixing the flange 26 at a position below the lower side surface 31a of the frame surface portion 31 and at a position separated from the lower side surface 31a by a distance corresponding to the thickness dimension of the flange 26. Is provided. The engagement protrusion 35 a is formed so as to protrude inside the connection protrusion 35 so as to contact the lower surface of the flange 26.
The connecting ridge 35 and the hooking protrusion 35a form a hooking portion.

As shown in FIGS. 1 to 6, a plurality of engaging projections 35a are provided over the entire circumference of the connecting projection 35 in the circumferential direction so as to be separated from each other. The engaging projection 35a is provided at each end position corresponding to each side of the opening of the container body 20 so as to fix the flange 26, and at the long side corresponding to the front face 22 and the rear face 23, the middle thereof. It is preferable to additionally provide on the side. Specifically, four engaging projections 35a can be provided on the long side, and two engaging projections 35a can be provided on the sides corresponding to the left and right side surfaces 24 and 25, respectively. Thereby, the rigidity of the frame body 30 and the container body 20 is maintained so that the frame body 30 and the flange 26 portion for exhibiting the child proof can be prevented from being deformed inadvertently so that the frame body 30 does not accidentally come off from the flange 26. Can be held.

As shown in FIGS. 1 to 6, the hooking protrusion 35a extends from the connecting protrusion 35 from the position of the outer peripheral end surface 26a of the flange 26 toward the center of the opening of the container body 20 or the frame body 30 in plan view. The protruding direction is set.

Thereby, the projecting direction of the engaging convex portion 35a, that is, the engaging direction with respect to the flange 26 is set so as to face the inner side (center side of the opening) on each side of the substantially rectangular flange 26. In order to remove from the body 30, the flange 26 is deformed so as to reduce its contour. Therefore, when such a deforming force is applied, the flange 26 is deformed by the connecting protrusions 35 on the opposite sides of the opening. Since the deformation of the frame is prevented, the engagement of the engagement protrusion 35a with the flange 26 is reliably maintained, the engagement between the frame body 30 and the container body 20 is maintained, and the frame body 30 and the container body 20 are released unexpectedly. Occurrence can be prevented.

As shown in FIGS. 1 to 6, the connecting projection 35 has a protrusion amount from the lower side surface 31 a of the frame surface portion 31 over the entire circumference thereof so that the frame surface portion 31 of the outer peripheral surface portion 32 and the inner peripheral surface portion 33 has a protrusion amount. It is set to be smaller than the protrusion amount (height dimension) from the lower side surface 31a. Thereby, the connecting ridge 35 fixes the flange 26 in the space surrounded by the frame surface portion 31, the outer peripheral surface portion 32, and the inner peripheral surface portion 33.

As shown in FIGS. 1 to 6, the connection protrusion 35 and the hooking protrusion 35a are provided with the frame 26 as a connecting portion, with respect to the flange 26 extending to the opening surface of the container body 20. It is provided at the center position in the width direction of the frame surface portion 31 that is connected so as to cover and is separated from the outer peripheral surface portion 32 that is the outer edge portion of the frame body 30.

As a result, it is possible to make the engaging protrusion 35 a less likely to come off the flange 26, as compared with the case where the connecting protrusion 35 is not provided and the engaging protrusion 35 a is directly connected to the outer peripheral surface part 32.

For example, when a child tries to open the container 10 with a lid by force, as shown by an arrow Ch in FIG. 4, the outer peripheral surface portion 32 is deformed so as to be peeled upward to deform the frame body 30 and the lid body 50 into the container body 20. The action force to disengage from is applied. Here, as shown in FIG. 12, when the connecting projection 35 is not provided and the engaging convex portion 35a is directly connected to the outer peripheral surface portion 32, the outer peripheral surface portion is against such an acting force. The deformation of 32 becomes the amount of movement of the engaging projection 35a as it is.

On the other hand, as shown in FIG. 4, when the engaging projection 35 a is connected to the connecting protrusion 35, the outer peripheral surface portion 32 is deformed by the action of such an action force of the frame surface portion 31. The amount of deformation of the connecting projection 35 through the deformation becomes the amount of movement of the engaging projection 35a.
When the engaging projection 35a is connected to the connecting projection 35, the action force is larger than the deformation amount of the outer peripheral surface portion 32 as shown in FIG. As shown in FIG. 4, the amount of deformation of the connecting protrusion 35 can be reduced. Therefore, it is possible to further prevent the engagement protrusion 35a from coming off the flange 26 due to the deformation of the connection protrusion 35.

Further, as shown in FIGS. 1 to 6, the frame surface portion 31 is located at a position corresponding to the engaging convex portion 35a in plan view in consideration of convenience of resin molding of the frame body 30 and the lid body 50. A through hole 31c is provided. Thereby, when the frame body 30 and the lid body 50 are resin-molded, the engaging convex portion 35a can be molded integrally with the connecting protrusion 35.

The locking portions 60, 70 enable locking/unlocking of the lid body 50 and the frame body 30, and as shown in FIGS. 1 to 6, on the front surface 22 side of the lid body 50 and the frame body 30. Two are provided. The locking portion 60 and the locking portion 70 are provided at both ends of the front surface portion 55 of the lid body 50 in the closed state, and are formed substantially symmetrically with respect to the center line of the lidded container 10.
The locking portion may be further provided at a position corresponding to the front surface 22 side or may be additionally provided at the left and right side surfaces 24, 25 side.

The locking portions 60, 70 are arranged so as to be spaced apart from each other by a predetermined distance d that is a child proof.
This distance d is such that the opening/closing operation can be performed with the size of an adult's hand, but the opening/closing operation cannot be performed with the size of the hand of a child, especially an infant. Specifically, FIGS. As shown in, the range is set to 80 mm to 130 mm, and more preferably set to 100 mm to 120 mm.
The child proof has a definition such as a packaging material devised in consideration of physical elements (size), strength, and structural comprehension.

As shown in FIGS. 1 to 6, the locking portions 60 and 70 include ribs 56 and 57 that extend horizontally and project forward at both end positions of the lower end of the front surface portion 55 on the lid body 50 side. Locking pieces 61, 71 extending upward from the left and right ends of the ribs 56, 57.
Further, as shown in FIGS. 1 to 6, the locking portions 60 and 70 are provided on the frame 30 side with ribs 56, at positions corresponding to both ends of the front surface portion 55 at the lower end of the outer peripheral surface portion 32 corresponding to the front surface 22. 57, ribs 36 and 37 that are set to substantially overlap with each other in a plan view and extend in the horizontal direction and project toward the front, and the ribs 36 and 37 are adjacent to the locking pieces 61 and 71 at the left and right ends thereof. Locking pieces 62 and 72 extending upward from the ribs 36 and 37 are provided as outer positions.

Other than the above, it may not be connected to the front surface portion 55. Further, the height dimension of the locking piece 62 is preferably half or less of the height dimension of the locking piece 61.
The portion of the locking piece 61 that is not hidden by the locking piece 62 in the closed state of the lid body 50 is a portion that the operator operates with his/her finger when performing the locking/releasing operation. Therefore, the height dimension of the locking piece 61 that is not hidden by the locking piece 62 when viewed from the right side surface 25 side in the closed state of the lid body 50 depends on the size and movement of an adult finger. It is preferable to set it so as to have an area for exerting an action force capable of causing sufficient elastic deformation to the locking piece 61.

In the locking portion 70, the locking piece 71 is provided so as to extend in a plane that passes through the front-back direction and the vertical direction that is a direction orthogonal to the rotation axis of the lid body 50 as the hinge 40, and the left and right sides thereof.

Other than the above, it may not be connected to the front surface portion 55. Further, the height dimension of the locking piece 72 is preferably half the height dimension of the locking piece 61 or less.
The portion of the locking piece 71 that is not hidden by the locking piece 72 in the closed state of the lid body 50 is a portion that the operator operates with his/her finger when performing the locking/releasing operation. Therefore, the height dimension of the locking piece 61 that is not hidden by the locking piece 72 when viewed from the left side surface 24 side in the closed state of the lid body 50 depends on the size and movement of an adult finger. It is preferable to set it so as to have an area for exerting an action force capable of causing sufficient elastic deformation to the locking piece 71.

In the locking parts 60 and 70, the locking pieces 61 of the respective locking parts 60 and the locking pieces 71 of the locking part 70, which are separated from each other, approach each other in the closed state of the lid body 50, that is, By elastically deforming inward in the left-right direction, the locking projections 63 and the locking projections 73 are disengaged from the locking recesses 64 and the locking recesses 74 that have been locked, respectively. The lock of 70 can be released.
Here, the elastic deformation of the locking piece 61 in which the locking convex portion 63 is disengaged from the locking concave portion 64 and the elastic deformation of the locking piece 71 in which the locking convex portion 73 is disengaged from the locking concave portion 74 occur simultaneously. If not operated, the locking of the locking portions 60 and 70 is not released, and the lid 50 cannot be opened and closed.

Further, the locking portions 60 and 70 are not provided with a configuration in which the locking piece 61 and the locking piece 71 come into contact with the operator's finger in the front direction and the vertical direction. Therefore, when the locking piece 61 and the locking piece 71 are operated, the tips of the operator's fingers do not come into contact with other parts of the lidded container 10. However, it is possible to suitably perform the opening/closing operation. This is important as a particularly suitable operating characteristic when storing toiletry products.

In the locking portions 60 and 70, the size of the locking projection 63 of the locking piece 61 and the locking recess 64 of the locking piece 62 in the opening/closing direction (vertical direction) and the locking of the locking piece 71.

FIG. 13 is a cross-sectional view for explaining the locking portion in this embodiment.

When the lid 50 is opened and closed, as shown by an arrow P in FIG. 13A, a deforming force is applied to the locking portion 60 and the locking portion 70 inward in the left-right direction. At this time, even if the locking portion 60 is locked, the locking portion 70 is not locked, or even if the locking portion 70 is locked, the locking portion 60 is locked. There is a possibility that it will not be done.

In order to prevent this one-sided hooking, as shown in FIG. 13B, the vertical dimension of the locking recess 64 and the vertical dimension of the locking recess 74 can be increased. In this case, even when the closing operation is performed in a state where the height positions of the locking projection 63 and the locking projection 73 are inclined, the locking projection 63 and the locking projection 73 are moved to the rib 36 side. The movable convex amount is increased so that the locking convex portion 63 and the locking convex portion 73 can move inside the locking concave portion 64 and the locking concave portion 74 until either of them is positively locked. be able to.

Here, even when the locking projection 63 and the locking projection 73 are in the locked state of the locking recess 64 and the locking recess 74 with the lid 50, the periphery of the lid 50 is the upper end of the outer peripheral surface portion 32. When there is a possibility that the fingers may be caught and the action force to release the fingers may be applied, as shown in FIG. 13(c), further, as shown in FIG. The lower surface can be inclined and the dimensions of the locking concave portion 64 and the locking convex portion 63 can be reduced to some extent to reduce play in the rotation of the lid 50. Here, the sloping surface of the locking projection 63 adjusts the vertical dimensional deviation from the locking recess 64, so that the upper end of the locking projection 63 ′ and the locking recess 64 are at a predetermined position. It becomes possible to engage accurately.

The opening/closing operation of the lidded container 10 of the present embodiment will be described below.
7 to 11 are perspective views showing the operation of the lidded container in the present embodiment.

First, in the lidded container 10 according to the present embodiment, in the closed state where the lid body 50 closes the opening, the front surface portion 55 overlaps with the front side position of the outer peripheral surface portion 32 as shown in FIG. 7. The locking piece 61 and the locking piece 62 are closest to each other at the facing position, and the ribs 56 and 36 are closest to each other at the facing position.
Further, as shown in FIGS. 1, 4, and 7, the closing ridges 52 provided around the lid body 50 are in contact with the upper surface of the frame surface portion 31, and the periphery of the lid body 50 is the outer peripheral surface portion 32. It is concealed by the upper end 32a and is protected so that fingers are not applied to the peripheral edge of the lid 50. Therefore, in the end portion of the lid body 50, only the lower end of the front surface portion 55 is in a position where the fingers are applied.

In the lidded container 10 according to the present embodiment, in the closed state where the lid body 50 closes the opening, as shown in FIG. 8, in the locking portion 60, the locking piece 61 is located outside in the left-right direction.

At the same time, in the locking portion 70, the locking piece 71 is in a state of approaching so as to face the locking piece 72 positioned on the outer side in the left-right direction, and the locking convex portion 73 is positioned in the locking concave portion 74. It is in a state to do.

In order to open the lid 50 from this state, the lid 50 needs to be rotated around the hinge 40, but the locking projection 63 is positioned inside the locking recess 64 and locked. At the same time, since the locking convex portion 73 is positioned and locked in the locking concave portion 74, even if a force is applied to move the lid body 50 upward with respect to the front surface portion 55, the lid body is closed. The positional relationship between the frame 50 and the frame body 30 does not change, and the lidded container 10 cannot be opened.

Next, as an unlocking step, as shown by an arrow P in FIG. 9, the operator's finger or the like is brought into contact with the upper ends of the locking pieces 61 and 71 to separate them in the left-right direction.

At the same time, the locking piece 71 elastically deforms inward in the left-right direction from the lower end on the rib 37 side.

The locking projection 63 is locked by following the deformation of the locking piece 61 and the locking piece 71 in the left-right direction, which is the direction in which the rotation axis of the lid 50 as the hinge 40 extends. The locking concave portion 64 is pulled out from the inside, and the locking convex portion 63 is unlocked by the locking concave portion 64. At the same time, the locking projection 73 is pulled out from the inside of the locking recess 74 where it was locked, and the locking of the locking projection 73 by the locking recess 74 is released.
As a result, the locking piece 61 can be moved upward with respect to the locking piece 62 without being disturbed by the rib 36, and the locking piece 71 can be moved upward with respect to the locking piece 72 without being disturbed by the rib 37. It is possible to move.

Thereby, the rigidity of the frame body 30A and the container body 20 is maintained so that the frame body 30A and the flange 26 portion for exhibiting the child proof are kept deformable and the frame body 30A does not accidentally come off from the flange 26. Can be held.

As shown in FIG. 14 to FIG. 18 and FIG. 1 to FIG. 6, the hooking convex portion 35a faces from the position of the outer peripheral end surface 26a of the flange 26 toward the opening center side of the container body 20 or the frame body 30A. The direction in which it projects from the connection ridge 35 is set.

Thereby, the projecting direction of the engaging convex portion 35a, that is, the engaging direction with respect to the flange 26 is set so as to face the inner side (center side of the opening) on each side of the substantially rectangular flange 26. In order to remove from the body 30A, the contour of the flange 26 is deformed so as to be contracted. Therefore, when such a deforming force is applied, the flange 26 is deformed by the connecting protrusions 35 on the opposite sides of the opening. Since the deformation of the frame is prevented, the engagement of the engagement protrusion 35a with the flange 26 is surely maintained, the engagement between the frame body 30A and the container body 20 is maintained, and the frame body 30A and the container body 20 are unexpectedly opened. Occurrence can be prevented.

As shown in FIG. 14 to FIG. 18 and FIG. 1 to FIG. 6, the connecting projection 35 has a protrusion amount from the lower side surface 31 a of the frame surface portion 31 over the entire circumference, and the outer peripheral surface portion 32 and the inner peripheral surface portion 33. It is set to be smaller than the protruding amount (height dimension) from the lower side surface 31a of the frame surface portion 31 at. Thereby, the connecting ridge 35 fixes the flange 26 in the space surrounded by the frame surface portion 31, the outer peripheral surface portion 32, and the inner peripheral surface portion 33.

As shown in FIGS. 14 to 18 and FIGS. 1 to 6, the connecting projection 35 and the engaging projection 35a are connected to the flange 26 extending from the opening surface of the container body 20 with the frame 30A. And is provided so as to cover the flange 26, and is provided at the center position in the width direction of the frame surface portion 31 which is separated from the outer peripheral surface portion 32 which is the outer edge portion of the frame body 30A.

As a result, it is possible to make the engaging protrusion 35 a less likely to come off the flange 26, as compared with the case where the connecting protrusion 35 is not provided and the engaging protrusion 35 a is directly connected to the outer peripheral surface part 32.

For example, when a child tries to open the lidded container 10, as shown by an arrow Ch in FIG. 4, the outer peripheral surface portion 32 is deformed so as to be peeled upward to transform the frame body 30A and the lid bodies 50A and 50B into containers. An acting force that tries to separate the main body 20 acts. Here, as shown in FIG. 12, when the connecting projection 35 is not provided and the engaging convex portion 35a is directly connected to the outer peripheral surface portion 32, the outer peripheral surface portion is against such a force. The deformation of 32 becomes the amount of movement of the engaging projection 35a as it is.

On the other hand, as shown in FIG. 4, when the engaging projection 35 a is connected to the connecting protrusion 35, the outer peripheral surface portion 32 is deformed by the action of such an action force of the frame surface portion 31. The amount of deformation of the connecting projection 35 through the deformation becomes the amount of movement of the engaging projection 35a.
When the engaging projection 35a is connected to the connecting projection 35, the action force is larger than the deformation amount of the outer peripheral surface portion 32 as shown in FIG. As shown in FIG. 4, the amount of deformation of the connecting protrusion 35 can be reduced. Therefore, it is possible to further prevent the engagement protrusion 35a from coming off the flange 26 due to the deformation of the connection protrusion 35.

Further, on the frame surface portion 31, as shown in FIGS. 14 to 18 and FIGS. 1 to 6, resin molding of the frame body 30A and the lid bodies 50A, 50B is performed at a position corresponding to the engaging convex portion 35a in plan view. The through hole 31c is provided in consideration of convenience at the time. Accordingly, when the frame body 30A and the lid bodies 50A and 50B are resin-molded, the engaging projection 35a can be molded integrally with the connecting protrusion 35.

The locking portions 60A and 70A enable locking and releasing of the lid body 50A and the lid body 50B and the frame body 30A.

The opening/closing operation of the lidded containers 10A and 50B of the present embodiment will be described below.
19, 20 and 22 are perspective views for showing the movement of the lidded container in the present embodiment, and FIGS. 21 and 23 are plan views for showing the movement of the lidded container in the present embodiment. Is.

First, in the lidded container 10A in the present embodiment, in the closed state in which the lids 50A and 50B close the openings, as shown in FIG. 19, the blocking ridges 52 provided around the lids 50A and 50B are provided. However, as shown in FIG. 19, it is in contact with the upper surface of the frame surface portion 31, and the periphery of the lids 50A and 50B is hidden by the upper end 32a of the outer peripheral surface portion 32, so that the fingers do not touch the peripheral edges of the lids 50A and 50B. As protected. Therefore, as the lids 50A and 50B, there is no end at the position where the fingers are applied.

Here, the lid surface portion 54B is located below the lid surface portion 54A, that is, inside the container body 20, and is not exposed on the surface. Further, the contour of the lid surface portion 54A is connected to the inner peripheral surface portion 53 of the lid body 50A or is in contact with the inner peripheral surface portion 53 of the lid body 50B. Further, in the boundary portion between the lid body 50A and the lid body 50B in the frame surface portion 51, there is a closed frame surface portion 51b in a position overlapping with the lower side thereof in plan view, and the lid body 50A and the lid in the closed ridge 52 are covered. A closed inner protrusion 52b extends in the gap at the boundary with the body 50B, and at the boundary between the lid 50A and the lid 50B in the inner peripheral surface 53, the closed inner peripheral surface 53b has an inner peripheral surface. It exists on the 33 side and closes these gaps.
As a result, the opening surface located inside the frame surface portion 31 is closed by the lids 50A and 50B.

Further, in the lidded container 10A in the present embodiment, in the closed state where the lids 50A and 50B close the openings, the front piece 57A is located at the front side position of the outer peripheral surface portion 32 as shown in FIGS. The rear surface piece 56A overlaps the rear side position of the outer peripheral surface portion 32, and the lower end 58 of the locking piece 61A and the rear surface piece 56A serves as a through hole for the locking piece 62A. In addition to being located below the recess 64A, the lower end 58 of the engaging piece 71A and the front piece 57A is located below the engaging recess 74A which is a through hole for the engaging piece 72A. Thus, the locking pieces 61A and the locking pieces 71A are in a state of being aligned with a height position parallel to the upper surface of the frame surface portion 31.

In order to open the lid body 50A from this state, it is necessary to rotate the lid body 50A around the hinge 40A, but the locking convex portion 63A is positioned and locked in the locking concave portion 64A. At the same time, since the locking projection 73A is positioned and locked in the locking recess 74A, it is assumed that a force acts so that the front surface piece 57A and the rear surface piece 56A move upward with respect to the outer peripheral surface portion 32. Also, the positional relationship between the lid 50A and the frame 30A does not change, and the opening of the lidded container 10A cannot be opened.

Next, as a first locking release step, as shown by an arrow P in FIG. 19, the operator's finger or the like is brought into contact with the upper ends of the locking pieces 61A and 71A to move in the front-back direction. In the separated locking portions 60A and 70A, the locking pieces 61A in the respective locking portions 60A and the locking pieces 71A in the locking portion 70A are deformed in a direction in which they approach each other, that is, inward in the front-rear direction. For example, they are simultaneously applied as compressive force.
As shown in FIG. 19, the locking piece 61A is elastically deformed from the lower end 58 in the forward direction by the deforming force acting on the upper ends of the locking pieces 61A and 71A toward the front-rear direction, and the locking pieces 61A are locked. The piece 71A elastically deforms rearward from the lower end 58.

The locking projection 63A is locked by following the deformation of the lid 50 as the hinge 40A in the locking piece 61A and the locking piece 71A in the front-back direction in which the rotation axis extends. The inside of the locking recess 64A is unlocked and can be pulled out. At the same time, the locking projection 73A is unlocked inside the locking recess 74A that was locked and can be pulled out.
As a result, the locking piece 61A and the rear surface piece 56A are rotated around the hinge 40A from the locking concave portion 64A without depending on the locking convex portion 63A, and the locking piece 61A is moved upward without being hindered by the locking piece 62A. It is possible to rotate the locking piece 71A and the front surface piece 57A around the hinge 40A from the locking recess 74A without depending on the locking projection 73A, so that the locking piece 71A becomes the locking piece 72A. It is possible to move upward without being disturbed.

As shown in FIG. 20, by applying an opening force in the direction of moving the right side of the lid body 50A upward in a state in which the engagement between the engagement portion 60A and the engagement portion 70A is released at the same time, as shown in FIG. Can rotate around the hinge 40A.

By rotating the lid 50A around the hinge 40A, as shown in FIG. 21, the closing projection 52 of the lid 50A releases the contact with the upper surface of the frame surface portion 31, and then the closing protrusion of the lid 50A. The strip 52 moves above the upper end 32a of the outer peripheral surface portion 32 to expose the left side portion of the frame body 30A, and the opening in the lidded container 10A is opened only at a portion corresponding to the lid body 50A. In this state, as shown in FIG. 21, the opening of the lidded container 10A is closed only at the portion corresponding to the lid 50B.

Next, as a second unlocking step, as shown in FIG. 22, the lid surface portion 54B whose movement toward the upper side is regulated by the lid surface portion 54A and the upward movement is regulated by the frame surface portion 51 of the lid body 50A. The closed frame surface portion 51b, the closed inner protruding portion 52b whose upper movement is restricted by the closing protruding portion 52 of the lid 50A, and the inner peripheral surface portion 53 of the lid 50A are restricted from moving upward. The closed inner peripheral surface portion 53b is rotated around the hinge 40A of the lid body 50A, so that the contact by the lid surface portion 54A, the frame surface portion 51, the closing ridge 52, and the inner peripheral surface portion 53 which are in contact with each other is released. The restriction on the rotation of the lid body 50B around the hinge 40B is released.

In this state, by applying an opening force in the direction of moving the left side of the lid body 50B upward, the lid body 50B can be rotated around the hinge 40BA as shown in FIG.

By rotating the lid body 50B around the hinge 40B, as shown in FIG. 23, the closing protrusion 52 of the lid body 50B releases the contact with the upper surface of the frame surface portion 31, and then the closing protrusion of the lid body 50B. The strip 52 moves above the upper end 32a of the outer peripheral surface portion 32 to expose the right side portion of the frame body 30A, and the opening portion closed by the lidded container 10B is also opened.

Further, the lid body 50B is rotated to be in a fully opened state as shown in FIG.

The container with lid 10A in the present embodiment is provided with locking portions 60A and 70A that are separated by a predetermined distance d to be a child proof, and the lids 50A and 50B are opened and closed by the locking portions 60A and 70A.

The rib 157 and the lower end portion of the wall surface 155g are connected by a rib 157a extending in a direction orthogonal to the rib 157, as shown in FIGS. 24 to 26 and 28 to 36. The rib 157a has a triangular shape when viewed from the front such that the height dimension becomes smaller from the wall surface 155g side toward the locking piece 171 side and the height dimension becomes zero on the locking piece 171 side. As a shape, it is provided on both sides of the upper surface of the rib 157.

The rib 157a allows the rib 157 to maintain rigidity without following deformation of the locking piece 171, and allows the locking piece 171 to rotate at a connection position with the rib 157 like a hinge. Becomes By this action and the position regulation of the wall surface 155g by the position regulation convex portion 166, it becomes possible to reliably lock and release the locking convex portion 173 with respect to the locking concave portion 174, as described later.

In the locking portion 170, as shown in FIGS. 24 to 36, at least the upper side of the locking piece 171 is not connected to the wall surface 155g, but to the lower end side fixed to the rib 157. The lid 150 as the hinge 140, which is the thickness direction, is erected in an elastically deformable state in the direction in which the rotation axis of the lid 150 extends. The locking surface 172 is erected so that the upper surface of the frame 131, the outer peripheral surface 132, the upper surface of the projection 137, and the opening side surface 137g are connected and fixed in four directions.
The locking piece 171 is provided with a ridge 171a continuous at the edges of the upper end portion and the side end thereof so as to correspond to the ridge 161a so as to project in the same direction as the locking projection 173. ing.

The locking piece 171 has a height dimension substantially equal to the height dimension of the notch 155 or the protrusion 151A, and can be connected to the wall surface 155g only at the lower end fixed to the rib 157. Further, the height dimension of the locking surface 172 is not more than half the height dimension of the locking piece 171, and the upper end of the locking surface 172 is flush with the upper end 132a of the outer peripheral surface portion 132. preferable.

In the closed state of the lid body 150, the portion of the locking piece 171 which is not hidden by the locking surface 172 in the cutout 155 when viewed in the left-right direction is touched by the operator when the locking/releasing operation is performed. It becomes a part to operate. Therefore, in the closed state of the lid body 150, the height dimension of the locking piece 171 not hidden by the locking surface 172 when viewed from the left side surface 124 side inside the notch 155 is the same as that of an adult finger. It is preferably set to have an area for exerting an acting force capable of generating elastic deformation sufficient for size and operation on the locking piece 161.

In the locking portions 160 and 170, the locking piece 161 in each locking portion 160 located in the notches 155 and 155 that are separated from each other in the left and right and the locking piece 171 in the locking portion 170 are provided in the lid 150. In the closed state, the locking projections 163 and the locking projections 173 are elastically deformed in a direction in which they approach each other, that is, inward in the left-right direction. The locks 160 and 170 can be unlocked by releasing the locks 160 and 170, respectively.
Here, the elastic deformation of the locking piece 161 in which the locking projection 163 is disengaged from the locking recess 164 and the elastic deformation of the locking piece 171 in which the locking projection 173 is disengaged from the locking recess 174 occur simultaneously. If not operated, the locks 160 and 170 are not unlocked, and the lid 150 cannot be opened or closed.

Further, in the locking portions 160 and 170, since the notches 155 are formed in the front direction and the rear direction of the locking pieces 61 and 71, a configuration is provided in which they are brought into contact with the fingers of the operator. Has not been done. Therefore, when the locking pieces 161 and 171 are operated, the tips of the fingers of the operator do not come into contact with other portions of the lidded container 100.

Further, since the inclined surfaces 155f and 155f are both formed to be inclined, the width dimension of the notch 155 is expanded from the rear side to the front side, and the width dimension of the notch 155 is lower. It is in a state of expanding from the top to. For this reason, even an operator with a long claw can perform the opening/closing operation preferably. This is important as a particularly suitable operating characteristic when storing toiletry products.

When the lid 150 is opened/closed, as shown by an arrow P in FIG. 30, the locking portions 160 and 170 are simultaneously subjected to a deforming force inward in the left-right direction. At this time, even if the locking portion 160 is locked, the locking portion 170 is not locked, or even if the locking portion 170 is locked, the locking portion 160 is locked. There is a possibility that it will not be done.

In order to prevent this one-sided hanging, as shown in FIGS. 30 to 32, it is possible to increase the vertical dimension of the locking recess 164 and increase the vertical dimension of the locking recess 174. In this case, even when the closing operation is performed in a state where the height positions of the locking projections 163 and 173 are inclined, the locking projections 163 and the locking projections 173 have the frame surface 131 side. The movable convex portion 163 and the convex locking portion 173 can be moved inside the locking concave portion 164 and the locking concave portion 174 until the movable concave portion 174 and the locking concave portion 174 are securely locked. can do.

Further, the lower end 132b of the outer peripheral surface portion 132 abuts on the upper surface 131b of the frame surface portion 131, so that the locking projection 163 and the locking projection 173 are reliably locked to the locking recess 164 and the locking recess 174. It becomes possible.

Here, when the locking convex portion 163 and the locking convex portion 173 are in the locked state of the locking concave portion 164 and the locking concave portion 174, the outer peripheral surface portion 132 covers the lower periphery of the protrusion 151A. The periphery of the lid 150 does not protrude from the upper end 132a of the outer peripheral surface portion 132. For this reason, there is no possibility that the fingers will be caught on the lid body 150 and the action force to open it will be exerted.

At the same time, even if the locking convex portion 173 of the one locking portion 160 is disengaged from the locking concave portion 174, the position control convex portions 165 and 166 may deform the lid body 150 in the left-right direction. Regulated. As a result, it is possible to prevent the locking convex portion 163 from coming off the locking concave portion 164, and prevent the lid 150 from being opened accidentally even in the state of one-sided hanging. Become.

The opening/closing operation of the lidded container 100 of the present embodiment will be described below.

First, in the lidded container 100 in the present embodiment, in the closed state where the lid body 150 closes the opening, as shown in FIG. 30, the protrusions 151A overlap the outer peripheral surface portion 32. At this time, the locking piece 161 and the locking surface 162 are in the state of being closest to each other at the facing position.

Further, as shown in FIG. 30, the protrusion 151A provided around the lid 150 is in contact with the upper surface 131b of the frame surface portion 131, and the periphery of the protrusion 151A is hidden by the upper end 132a of the outer peripheral surface portion 132. The peripheral edge of the lid body 50 is protected so that fingers are not applied. Therefore, in the end portion of the lid body 150, only the upper end of the front surface portion 55 of the protrusion 151A is in a position where the fingers are applied, but since the upper side of the protrusion 151A is formed as a curved surface, in this state, The lid 150 cannot be opened.

In the lid-equipped container 100 according to the present embodiment, in the closed state where the lid body 150 closes the opening, as shown in FIG. 30, in the locking portion 160, the locking piece 161 has the left-right direction inside the notch 155. It is in a state of approaching so as to face the locking surface 162 located outside, and the locking projection 163 is locked by the locking projection 164a. At the same time, in the locking portion 170, the locking piece 171 is in a state of approaching so as to face the locking surface 172 located on the outer side in the left-right direction inside the notch 155, and the locking convex portion 173 is locked. It is in a state of being locked to the portion 174a.

In order to open the lid body 150 from this state, it is necessary to rotate the lid body 150 around the hinge 140, but inside the notch 155, the locking projection 163 is locked by the locking projection 164a. In addition, since the locking projection 173 is locked by the locking projection 174a, a force cannot be applied to move the lid body 150 upward with respect to the frame body 130. The positional relationship between 150 and the frame body 130 does not change, and the lidded container 100 cannot be opened.

In addition, the left and right ends of the rib 156 on the base side of the locking piece 161 are in contact with and sandwiched between the convex portions 164b, 164c and the position regulating convex portion 165, and the rib on the base side of the locking piece 171 is formed. The left and right ends of 157 are in contact with the protrusions 174b and 174c and the position regulating protrusion 166 so as to be sandwiched therebetween, thereby preventing the locking portions 160 and 170 from coming off. At the same time, even when either the locking portion 160 or the locking portion 170 is unlocked, the other locking state can be maintained and high child proof performance can be exhibited.

At the same time, the locking projection 163, the locking projection 164a, the locking projection 173, and the locking projection 174a are all located below the upper end 132a of the outer peripheral surface portion 132 in the cutout 155, Since the regulation convex portion 165 and the position regulation convex portion 166 are covered with the protrusions 151A, it is possible to maintain a state in which the locking portions 160 and 170 are not easily disengaged even by an impact such as a drop.

Next, as an unlocking step, as shown by an arrow P in FIG. 30, the operator's finger or the like is brought into contact with the upper ends of the locking pieces 161 and 171 to separate them in the left-right direction. In the locking portions 160 and 170, the locking pieces 161 of the locking portions 160 and the locking pieces 171 of the locking portions 170 are deformed toward each other in a direction in which they approach each other, that is, inward in the left-right direction, for example. Act as force simultaneously.
The deforming force acting on the upper ends of the locking pieces 161 and 171 toward the inner side in the left-right direction elastically deforms the locking piece 161 from the lower end on the rib 156 side to the inner side in the left-right direction, and The lower end on the rib 157 side is elastically deformed inward in the left-right direction.

The locking projections 163 are locked by following the deformation of the locking piece 161 and the locking piece 171 in the left-right direction, which is the direction in which the rotation axis of the lid 150 as the hinge 140 extends. The locking projection 164a is pulled out from below and the locking projection 163 is unlocked by the locking projection 164a. At the same time, the locking projection 173 is pulled out from the lower side of the locking projection 174a that was locked, and the locking projection 173 is unlocked by the locking projection 174a.
This allows the locking piece 161 to move upward relative to the locking piece 162 without being disturbed by the outer peripheral surface portion 132, and the locking piece 171 is not disturbed by the outer peripheral surface portion 132 with respect to the locking piece 172. It is possible to move to the upper side.

With the locking of the locking portion 160 and the locking portion 170 released at the same time, an opening force is applied in a direction to move the front side of the lid body 150 upward, so that the lid body 150 rotates around the hinge 140. It becomes possible to do.

By rotating the lid 150 around the hinge 140, as shown in FIGS. 31 and 32, the protrusion 151A releases the contact with the upper surface 131b of the frame surface portion 131, and then the protrusion 151A moves to the outer peripheral surface portion. The frame body 130 is exposed to the upper side of the upper end 132a of the 132 to expose the frame 130, and the opening in the lidded container 100 is opened.

Further, the lid 150 is rotated to bring it into an open state as shown in FIGS. 25 to 26.

The lidded container 100 according to the present embodiment is provided with locking portions 160 and 170 which are separated by a predetermined distance d to be a child proof, and the lid body 150 is opened and closed by the locking portions 160 and 170. It is possible to provide a container with a lid, which can be provided at a low cost while reliably realizing the above, can display loaded products, can save space during transportation, and has a predetermined strength.

Furthermore, the ribs 156a and 157a enable the ribs 156 and 157 to maintain rigidity without following deformation of the locking pieces 161 and 171, so that the locking pieces 161 and 171 can change the connection position with the ribs 156 and 157. It becomes possible to move like a hinge and the wall surface 155g is position-regulated by the position-regulating convex portions 165 and 166, so that the lid body 150 is deformed in the left-right direction with respect to the frame body 130. This can be prevented, and the locking projections 163, 173 can be reliably locked and released with respect to the locking projections 164a, 174a.

Thereby, for example, even when a child tries to open the lid-equipped container 100, the lid-equipped container 100 cannot be opened except to deform the locking pieces 161 and 171 so that the child proof is completely removed. It can be anything. At the same time, it is possible to prevent the lidded container 100 from being opened accidentally due to the deformation of the lid body 150.
