AI Technical Summary
Existing box-shaped containers lack effective childproof mechanisms and have suboptimal operability, particularly in releasing the restricting state of the lid.
The container features a lid connected to a frame via a hinge, with a first restricting portion on the frame and a second restricting portion on the lid. The second restricting portion is elastically deformable and can be displaced to release the restriction, requiring a specific sequence of operations to open the lid.
This design enhances childproof security by making it difficult for unauthorized users to open the container, while also improving operability for intended users by allowing easy and intuitive opening with enhanced usability.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a box-shaped container. [Background technology]
[0002] Conventionally, a box-shaped container has been proposed that includes a cylindrical container body with a bottom that accommodates contents, a frame body disposed around the edge of the upper opening of the container body, and a lid body that is connected to the frame body via a hinge and that opens and closes the opening of the frame body (see, for example, Patent Document 1). In such a box-shaped container, first and second restricting portions are formed separately on the frame body and the lid body that restrict movement of the lid body around the hinge to an open position relative to the frame body when the lid body is in a closed position that closes the opening of the frame body, and a knob portion is formed on the lid body that faces the hinge. Then, by pushing the knob portion toward the hinge, the restriction by the first and second restricting portions formed on the frame body and the lid body is released, and the lid body can rotate around the hinge relative to the frame body to the open position, opening the opening of the frame body. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-131257 Summary of the Invention [Problem to be solved by the invention]
[0004] However, even in such a box-shaped container, there is room for improvement in providing a childproof function that more reliably prevents people who are not permitted to open the box-shaped container, such as small children, from easily touching the contents of the container body. Also, in the above-mentioned box-shaped container, in order to release the restricting state of the first and second restricting parts, it is necessary to rotate the lid body around the hinge relative to the frame body while pushing the knob part toward the hinge, and there is a demand for further improvement in operability.
[0005] The present invention has been made in view of the above-mentioned problems, and has an object to provide a box-shaped container that is childproof and has improved operability. [Means for solving the problem]
[0006] The present invention employs the following means to solve the above-mentioned problems. That is, the box-shaped container of the present invention comprises a cylindrical container body with a bottom that accommodates contents, a frame disposed on the edge of the upper opening of the container body, and a lid connected to the frame body via a hinge and covering the opening of the frame body in an openable and closable manner, the frame having a frame flange portion placed on the edge of the upper opening of the container body and a frame peripheral wall portion extending downward from the outer periphery of the frame flange portion, the lid having a lid flange portion placed on the frame flange portion and a lid peripheral wall portion extending downward from the outer periphery of the lid flange portion and disposed outside the frame peripheral wall portion, and the frame peripheral wall portion has a hinge that restricts the lid body from rotating around the hinge to open the opening. a first restricting portion formed on the lid peripheral wall portion, the second restricting portion being engageable with the first restricting portion from below when the lid body is in a closing position that closes the opening, at least one of the first and second restricting portions being formed to be elastically deformable in the radial direction, and in accordance with the elastic deformation of at least one of the first and second restricting portions, the second restricting portion is displaced between a position where it can be engaged with the first restricting portion from below the first restricting portion and a position where restriction by the first restricting portion is released, and the lid peripheral wall portion surrounds the second restricting portion from the outside.
[0007] In this invention, when the lid is in the closed position, blocking the opening of the frame, attempting to rotate the lid around the hinge relative to the frame restricts the lid's rotation around the hinge by engaging the second restricting portion of the lid with the first restricting portion of the frame from below. To release the restriction on the lid's rotation around the hinge, the second restricting portion must be operated from the lower end opening of the lid peripheral wall, as it is surrounded from the outside by the lid peripheral wall. This makes it difficult for the non-eligible person to operate the second restricting portion. This reduces the possibility of the non-eligible person operating the lid and unintentionally opening the container body. Furthermore, the need to hook a finger or the like on the second restricting portion and pull the second restricting portion outward, and then rotate the lid around the hinge in this state, also reduces the possibility of the non-eligible person operating the lid and unintentionally opening the container body. On the other hand, for the above-mentioned subject, by pulling the second restricting part outward to release the restriction by the first restricting part and then lifting up the lid body, the lid body can be rotated around the hinge relative to the frame body to the open position, thereby opening the opening, thereby improving the operability of the lid body. When the lid body in the open position is rotated around the hinge, the second regulating portion is displaced outward from the first regulating portion due to elastic deformation of at least one of the first and second regulating portions, and overcomes the first regulating portion, and then displaces inward to a position where it can be engaged with the first regulating portion from below.In this way, simply by rotating the lid body around the hinge relative to the frame body, the rotation of the lid body around the hinge can be restricted again. As a result, it is possible to provide a childproof function and improve operability.
[0008] In the present invention, the first and second restricting portions may be separately disposed on portions of the frame and the cover that are located on the opposite side from the hinge. In this invention, when the cover is in the closed position, the operation of displacing the second restricting part outward relative to the first restricting part moves the second restricting part away from the hinge, and this operation can be easily performed in succession with the subsequent operation of lifting the cover and rotating it around the hinge, further improving the operability of the cover.
[0009] In addition, in the present invention, the first regulating portion may be formed with an outer displacement guide surface against which a lower end edge of the second regulating portion abuts to guide outward displacement of the second regulating portion relative to the first regulating portion. In this invention, when the cover is rotated from the open position around the hinge toward the closed position, the outer displacement guide surface guides the second restricting portion to a position outside the first restricting portion, making it easier for the second restricting portion to pass over the first restricting portion during rotation to the closed position, further improving the operability of the cover.
[0010] In addition, in the present invention, an inner surface of the second regulating portion may be formed with an inner displacement guide surface that guides inward displacement of the second regulating portion to a position where it can be engaged with the first regulating portion from below. In this invention, when the second restricting part, which is displaced outward relative to the first restricting part as the cover is rotated around the hinge from the open position toward the closed position, is displaced inward, the second restricting part is guided by the inner displacement guide surface, thereby further improving the operability of the cover. [Effects of the Invention]
[0011] According to the box-shaped container of this invention, the second regulating part is surrounded from the outside by the lid peripheral wall part, making it difficult for non-target persons to operate the second regulating part. In addition, in order to rotate the lid body around the hinge, it is necessary to hook a finger or the like around the second regulating part from the lower end opening of the lid peripheral wall part and pull it outward. This more reliably reduces the possibility that the non-target person will unintentionally open the container body. On the other hand, for the target person, by pulling the second regulating part outward and lifting the lid body, the lid body can be rotated around the hinge relative to the frame body and the opening can be opened, thereby improving the operability of the lid body.

[0013] Hereinafter, an embodiment of a box-shaped container according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the box-shaped container 1 of this embodiment comprises a bottomed rectangular cylindrical container body 2 for accommodating contents, a rectangular frame body 3 attached to the container body 2, and a rectangular plate-shaped lid body 5 connected to the frame body 3 via a hinge 4 and capable of covering the opening of the frame body 3 in an openable and closable manner. Hereinafter, the central axis of the container body 2 will be referred to as the container axis O, and in Fig. 1, the direction from the bottom of the container body 2 toward the opening along this container axis O will be referred to as the upward direction, and the opposite direction will be referred to as the downward direction. Furthermore, the direction intersecting the container axis O in a plan view seen from the container axis O will be referred to as the radial direction, and the direction going around the container axis O will be referred to as the circumferential direction. Furthermore, the direction in which the long sides of the container body 2, frame 3, and lid 5, which are rectangular in plan view, extend will be referred to as the left-right direction, and the direction in which the short sides extend will be referred to as the front-rear direction.
[0014] 1, the container body 2 includes a bottomed rectangular cylindrical body 11 and a container flange 12 that projects radially outward from the upper edge of the body 11 along the entire periphery. The body 11 and the container flange 12 are arranged coaxially with the container axis O.
[0015] 1 to 6, the frame 3 includes a frame flange portion 21 having a rectangular annular shape in a plan view, a frame inner peripheral wall portion 22 having a rectangular cylindrical shape extending downward from the inner peripheral edge of the frame flange portion 21, and a frame outer peripheral wall portion (frame peripheral wall portion) 23 having a rectangular cylindrical shape extending downward from the outer peripheral edge of the frame flange portion 21. The frame flange portion 21, the frame inner peripheral wall portion 22, and the frame outer peripheral wall portion 23 are arranged coaxially with the container axis O.
[0016] The frame flange 21 is placed on the container flange 12. In addition, a die-removal opening 21A is formed on the front and rear edges of the frame flange 21 to enable die-removal when forming the mounting claws 23B described below. A plurality of die-removal openings 21A are formed at intervals in the left-right direction.
[0017] A frame cutout 23A that opens downward is formed in the left-right center of the front wall of the frame outer peripheral wall 23. The left-right center of the frame cutout 23A extends higher than both left and right sides. That is, the frame cutout 23A has a "convex" shape when viewed from the front. The front wall of the frame outer peripheral wall 23 is formed with a first restricting portion 24 that protrudes forward from a portion of the front wall that defines the upper opening edge of the "convex"-shaped frame cutout 23A. The first restricting portion 24 includes a restricting top wall portion 25 that protrudes forward from the opening edge of the frame cutout 23A on the front wall of the frame outer peripheral wall 23; a pair of restricting side wall portions 26 that extend downward from both left and right edges of the restricting top wall portion 25; and a restricting front wall portion 27 that extends downward from the upper edge of the restricting top wall portion 25. The restricting top wall portion 25 and the restricting front wall portion 27 are smoothly connected, and the outer surface of the connecting portion between the restricting top wall portion 25 and the restricting front wall portion 27 is rounded. As a result, the outer surface of the connecting portion forms the outer displacement guide surface 24A. The restricting front wall portion 27 extends downward beyond the restricting side wall portion 26.
[0018] A plurality of mounting claws 23B projecting rearward are formed at intervals in the left-right direction at the lower end of the front wall of frame outer peripheral wall 23, and a plurality of mounting claws 23B projecting forward are similarly formed at intervals in the left-right direction at the lower end of the rear wall of frame outer peripheral wall 23. These mounting claws 23B are formed at positions that overlap with die-cut opening 21A in plan view, and engage with container flange 12 from below.
[0019] The lid body 5 includes a lid flange portion 31 having a rectangular annular shape in a plan view, a lid inner peripheral wall portion 32 having a rectangular cylindrical shape extending downward from the inner peripheral edge of the lid flange portion 31, a lid outer peripheral wall portion (lid peripheral wall portion) 33 having a rectangular cylindrical shape extending downward from the outer peripheral edge of the lid flange portion 31, and a lid bottom wall portion 34 having a rectangular shape in a plan view and whose outer peripheral edge is connected to the lower end of the lid inner peripheral wall portion 32. The lid flange portion 31, the lid inner peripheral wall portion 32, the lid outer peripheral wall portion 33 and the lid bottom wall portion 34 are arranged coaxially with the container axis O.
[0020] The lid flange 31 is placed on the frame flange 21. A forward-projecting top wall 31A that projects forward is formed in the left-right central portion of the front edge of the lid flange 31. A downward-projecting protruding rib 31B is formed on the underside of the forward-projecting top wall 31A. The protruding rib 31B extends in the left-right direction and is adjacent to or in contact with the upper surface of the restricting top wall 25. Additionally, downwardly projecting abutment ribs 31C are formed on the underside of both the left and right sides of the forward-projecting top wall portion 31A formed on the front edge of the lid flange portion 31. The abutment rib 31C is H-shaped when viewed from below and abuts or is close to the upper surface of the frame flange portion 21. Similarly, one abutment rib 31C is formed on the underside of each of the left and right edges of the lid flange portion 31. The shape of the abutment rib 31C can be modified as appropriate, and it may be formed in multiple locations. Note that the abutment rib 31C may be formed anywhere on the underside of the lid flange portion 31, excluding the area where the forward-projecting top wall portion 31A is formed.
[0021] The lid inner peripheral wall portion 32 extends downward beyond the frame inner peripheral wall portion 22 . Like the lid inner peripheral wall 32, the lid outer peripheral wall 33 extends downward below the frame outer peripheral wall 23. A forward-projecting peripheral wall 35 that projects forward is formed in the left-right central portion of the front wall of the lid outer peripheral wall 33. The forward-projecting peripheral wall 35 projects downward below the lid outer peripheral wall 33. The forward-projecting peripheral wall 35 has a pair of side peripheral wall portions 36 and a front peripheral wall portion 37 that connects the front edges of the side peripheral wall portions 36. The upper edge of the forward-projecting peripheral wall 35 is connected to the edge of the forward-projecting peripheral wall portion 35 of the lid outer peripheral wall 33.
[0022] A second restricting portion 38 that connects the side peripheral wall portions 36 to each other is formed at the lower end of a pair of side peripheral wall portions 36 of the forward-protruding peripheral wall portion 35. The second restricting portion 38 is a plate-shaped member extending in the left-right direction. The upper edge of the second restricting portion 38 is located lower than the lower surface of the lid flange portion 31, and the lower edge of the second restricting portion 38 is at the same height as the lower edge of the forward-protruding peripheral wall portion 35. The first restricting portion 24 is inserted into the gap between the upper edge of the second restricting portion 38 and the lower surface of the lid flange portion 31. That is, the restricting top wall portion 25 and the restricting side wall portion 26 of the first restricting portion 24 pass through the gap in the front-rear direction, and the restricting front wall portion 27 of the first restricting portion 24 is located outward of the second restricting portion 38. The lower edge of the restricting front wall portion 27 is located lower than the upper edge of the second restricting portion 38, and the outer surface of the upper end of the second restricting portion 38 faces the inner surface of the lower end of the restricting front wall portion 27 in the front-to-rear direction and is close to or abuts against the inner surface of the lower end of the restricting front wall portion 27. This allows the second restricting portion 38 to be engaged with the first restricting portion 24 from below, and when the lid body 5 is in the closing position closing the opening 3A of the frame body 3, the lid body 5 is restricted from rotating around the hinge 4 relative to the frame body 3.
[0023] The second restricting portion 38 has an inner displacement guide surface 38A formed on the inner surface of the upper end thereof, which is an inclined surface that slopes forward as it extends upward. The lid bottom wall 34 has a rising wall 34A rising upward from the lower edge of the lid inner peripheral wall 32, and a closing wall 34B connected to the upper edge of the rising wall 34A. The lid bottom wall 34 covers the opening 3A of the frame 3 from above.
[0024] Next, a method of using the box-shaped container 1 configured as above will be described. When the lid body 5 is in the closed position closing the opening 3A of the frame body 3, the first restricting portion 24 extends in the front-to-rear direction above the upper edge of the second restricting portion 38, and the restricting front wall portion 27 of the first restricting portion 24 is positioned outward of the second restricting portion 38. Therefore, even if the lid body 5 is attempted to be rotated around the hinge 4 relative to the frame body 3, the second restricting portion 38 engages with the first restricting portion 24 from below. Therefore, rotation of the lid body 5 around the hinge 4 relative to the frame body 3 is restricted. Furthermore, rotation of the lid body 5 around the hinge 4 relative to the frame body 3 is also restricted because the outer surface of the upper end of the second restricting portion 38 faces the inner surface of the lower end of the restricting front wall portion 27 in the front-to-rear direction.
[0025] To rotate the cover 5 around the hinge 4 relative to the frame 3, first, for example, insert the index finger of one hand into the second restriction portion 38 from the lower opening edge of the cover 5 and pull the second restriction portion 38 forward. The second restriction portion 38 is a plate-shaped member whose left and right sides are connected to the cover outer peripheral wall portion 33, making it easily elastically deformable in the front-to-rear direction. When the second restriction portion 38 is pulled forward, the second restriction portion 38 deforms so as to tilt around its vertical center. As a result, the second restriction portion 38 tilts from rear to front as it moves from the lower edge to the upper edge. When the second restriction portion 38 is continued to be pulled forward in this state, the second restriction portion 38 is in a forward tilted state, so the lower edge of the restriction front wall portion 27 of the first restriction portion 24 is guided along the front surface of the second restriction portion 38. As a result, the second restricting portion 38 is pulled out further forward than the first restricting portion 24, and the restriction of the second restricting portion 38 by the first restricting portion 24 is released.
[0026] When the lid body 5 is pulled upward around the hinge 4 with the second restricting portion 38 climbing over the first restricting portion 24 at the rear, the opening 3A of the frame body 3 is opened, the lid body 5 reaches the open position, and the container body 2 is opened. Here, the first and second restricting portions 24, 38 are separately provided on the front wall portions of the frame body 3 and the lid body 5 located on the opposite side from the hinge 4, so that the operation of pulling the second restricting portion 38 outward is followed successively by the operation of rotating the lid body 5 around the hinge 4 relative to the frame body 3. In this way, the opening 3A of the frame 3 is opened.
[0027] After the contents of the opened box-shaped container 1 are appropriately removed, the lid 5 is rotated in the opposite direction around the hinge 4 relative to the frame 3. When the lid 5 is rotated around the hinge 4 relative to the frame 3, the lower edge of the second restricting portion 38 abuts against the upper surface of the restricting top wall portion 25 of the first restricting portion 24, as shown in FIGS. 7 and 8 . When the lid 5 is rotated in this state, the second restricting portion 38 elastically deforms so that its lower edge faces outward. The lower edge of the second restricting portion 38 is then guided along the restricting top wall portion 25 and the restricting front wall portion 27 of the first restricting portion 24, elastically deforming the second restricting portion 38 outward. Here, because the outer displacement guide surface 24A is formed at the connection between the restricting top wall portion 25 and the restricting front wall portion 27 of the first restricting portion 24, the second restricting portion 38 elastically displaces smoothly outward from the first restricting portion 24 along the outer displacement guide surface 24A.
[0028] When the second restricting portion 38 climbs over the first restricting portion 24, the second restricting portion 38 undergoes restoration deformation inward. At this time, since an inner displacement guide surface 38A is formed on the inner surface of the upper end portion of the second restricting portion 38, the second restricting portion 38 moves past the lower end edge of the restricting front wall portion 27 of the first restricting portion 24 and undergoes restoration displacement inward. As a result, the second restricting portion 38 engages with the first restricting portion 24 from below, once again restricting rotation of the cover body 5 around the hinge 4 relative to the frame body 3. The box-shaped container 1 is used in the above manner.
[0029] As described above, according to the box-shaped container 1 of this embodiment, the second restricting portion 38 is surrounded from the outside by the lid outer peripheral wall portion 33, making it difficult to catch a finger on the second restricting portion 38, and since it is necessary to pull the second restricting portion 38 outward and lift the lid body 5 in order to rotate the lid body 5 about the hinge 4, it is possible to reduce the possibility that the non-target person will unintentionally open the container body 2 when attempting to rotate the lid body 5 about the hinge 4 relative to the frame body 3. On the other hand, for the target person, the second restricting portion 38 can be pulled outward relative to the first restricting portion 24 to release the restriction by the first restricting portion 24, and then the lid body 5 can be lifted up to rotate the lid body 5 about the hinge 4 relative to the frame body 3 and open the opening 3A of the frame body 3, thereby improving the operability of the lid body 5.
[0030] Here, the first and second regulating parts 24, 38 are separately provided on the front wall parts of the frame body 3 and the lid body 5 located on the opposite side of the hinge 4, and when the lid body 5 is in the closed position, the operation of pulling the second regulating part 38 outward relative to the first regulating part 24 to release the regulated state of the second regulating part 38 and then lifting the lid body 5 to rotate it around the hinge 4 are performed consecutively, thereby further improving the operability of the lid body 5. Furthermore, when the cover body 5 is rotated around the hinge 4 from the open position toward the closed position, the second regulating portion 38 is guided by the outer displacement guide surface 24A to elastically displace outward relative to the first regulating portion 24, and by the inner displacement guide surface 38A to elastically displace inward relative to the first regulating portion 24, thereby further improving the operability of the cover body 5.
[0031] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the frame and lid are integrally formed with a hinge, but they may also be formed as separate components and then connected to each other by a hinge formed integrally with the frame or lid, or by a hinge formed as a separate component. The frame is attached to the container body by engaging mounting claws provided on the outer peripheral wall of the frame with the container flange, but it may also be attached to the container body using other methods, such as other types of fastening means or adhesive. The mounting claws are provided on the front and rear walls of the outer peripheral wall of the frame, but they may also be formed on other parts, such as the side walls. The frame and lid do not necessarily have inner peripheral wall portions. The container body has a container flange portion on which the frame flange portion is placed, but it does not have to have a container flange portion as long as it has a structure in which the frame flange portion can be placed. A plurality of first and second restricting portions may be provided. Here, a plurality of second restricting portions may be provided corresponding to one first restricting portion, or a plurality of first restricting portions may be provided corresponding to one second restricting portion. For example, when a plurality of first and second restricting portions are provided separately and spaced apart on the front wall portions of the frame body and the lid body located on the opposite side from the hinge, providing a plurality of second restricting portions in a range where a plurality of fingers (for example, the index finger and middle finger of one hand when two second restricting portions are provided) can simultaneously reach the plurality of second restricting portions, thereby further reducing the possibility of the container body being unintentionally opened and improving the operability of the lid body. The first restricting portion is inserted into a gap defined above the second restricting portion, but may have another configuration as long as the second restricting portion is configured to be lockable from below. The first restricting portion has a shape in which the lower end of the restricting front wall portion faces the upper end of the second restricting portion in the front-rear direction, but may have another shape as long as the second restricting portion is configured to be lockable from below. The second regulating portion is configured to be displaced in the front-to-rear direction relative to the first regulating portion by elastic displacement and restoring displacement, but it is sufficient that the second regulating portion is configured to be displaced in the front-to-rear direction relative to the first regulating portion by elastic displacement and restoring displacement of at least one of the first and second regulating portions. The first restricting portion has an outer displacement guide surface, but does not necessarily have to have the outer displacement guide surface as long as the second restricting portion can be elastically displaced outward during the process of moving the cover body around the hinge relative to the frame body to the closed position. Similarly, the second restricting portion has an inner displacement guide surface, but does not necessarily have to have the outer displacement guide surface as long as the second restricting portion can be restored and displaced more inward than the first restricting portion during the process of moving the cover body around the hinge relative to the frame body to the closed position. Furthermore, the outer displacement guide surface may be formed on a member separate from the first restricting portion. Similarly, the inner displacement guide surface may be formed on a member separate from the second restricting portion. The first and second restricting portions are formed on the front edges of the cover and frame, which are located on the opposite side from the hinge, but may be formed on other locations, such as the side edges. In describing each component, such as the container body, frame, and lid, they are described as being "rectangular," but they may be any other shape as appropriate, such as circular, elliptical, or other polygonal shapes such as triangular.
