However, even in such a box-shaped container, a child proof is used to prevent a non-target person who is not allowed to open the box-shaped container, such as an infant, from easily touching the contents of the container body. There was room for improvement in giving the function. In the box-shaped container described above, the non-target person unintentionally releases the locked state between the first locking portion and the second locking portion by grasping the top wall portion and the front wall portion of the lid. At the same time, the lid may be rotated around the hinge with respect to the container body. In particular, infants who are not the above-mentioned non-target persons are not dexterous with their fingertips as compared with adults, and tend to grasp the top wall and front wall of the lid, so that the container body may be opened unintentionally. be.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a box-shaped container having a child-proof function.

The present invention employs the following means to solve the above problems. That is, the box-shaped container of the present invention is connected to the bottomed tubular container body for accommodating the contents, the frame body arranged at the upper end opening edge of the container body, and the frame body via a hinge. A lid body that covers the opening of the frame body so as to be openable and closable, and the frame body is placed on the upper end opening edge of the container body from the frame flange portion and the inner peripheral edge of the frame flange portion. It extends downward, is inserted into the upper end opening of the container body, and has a frame peripheral wall portion provided with a first locking portion, and the lid body is placed on the frame flange portion. A second engagement that extends downward from the inner peripheral edge of the lid flange portion and the lid flange portion, is inserted inside the frame peripheral wall portion, and can be locked from below with respect to the first locking portion. There is a lid peripheral wall portion provided with a stop portion, and a knob portion that is elastically deformable is provided in a portion of the lid flange portion that faces the hinge with the container shaft of the container body sandwiched in the radial direction. It is provided, and is characterized in that the radial outer end position of the knob portion is equivalent to the radial outer end position of the frame flange portion.

In the present invention, the grip portion does not sufficiently protrude outward in the radial direction with respect to the frame flange portion, and it is difficult for the non-target person to perform the action of hooking a finger on the grip portion and lifting the grip portion. Since the operation of the knob portion is restricted, it is possible to prevent the box-shaped container from being opened by the non-target person. Here, unlike the box-shaped container described above, the lid body is not provided with the front wall portion of the outer peripheral wall portion, so that the non-target person may grab the lid body and unintentionally open the container body. Can be reduced more reliably.
On the other hand, the subject who is allowed to open the box-shaped container hooks the gripped portion on a finger by sandwiching the gripped portion and the peripheral wall portion of the lid in the radial direction, and then rolls up the gripped portion. Here, since the subject has a dexterous fingertip as compared with, for example, an infant, the subject can operate the picking portion by hooking a finger on the picking portion. Then, with the subject's finger resting on the rolled-up knob, the lid is pulled up with respect to the frame and rotated around the hinge. When the lid body is rotated around the hinge with respect to the frame body, the locked state between the first locking portion and the second locking portion is released. Here, since the contact area between the picking portion and the finger of the target person is increased by rolling up the picking portion, the operability of opening the box-shaped container with respect to the target person is improved. As a result, the box-shaped container is opened.
In this way, since the operation of the knob portion is restricted by the non-target person, the box-shaped container can be provided with a childproof function.

Further, in the present invention, the portion of the peripheral wall portion of the frame facing the hinge in the radial direction is urged toward the hinge with the portion of the peripheral wall portion of the lid facing the hinge in the radial direction. A leaf spring portion may be provided.
In the present invention, when the box-shaped container is opened, the inner peripheral surface of the lid peripheral wall portion is pushed outward in the radial direction to elastically deform the leaf spring portion, so that the knob portion is elastically displaced outward in the radial direction. Therefore, it becomes easier for the subject to operate the knob. Further, by restoring and deforming the leaf spring portion, the knob portion retracts inward in the radial direction with respect to the frame flange portion, so that it is possible to more reliably regulate the opening of the box-shaped container by the non-target person.

According to the box-shaped container according to the present invention, the knob portion does not sufficiently project outward in the radial direction with respect to the frame flange portion, and while restricting the operation of the knob portion by the non-target person, while restricting the operation of the knob portion. Since the knob can be operated by the subject, the box-shaped container can be provided with a childproof function. Further, since the contact area between the picking portion and the finger of the target person is increased by rolling up the picking portion, the operability of opening the box-shaped container with respect to the target person is improved.

Further, the direction in which the long side portions of the container body 2, the frame body 3 and the lid 5 having a rectangular shape in a plan view extend is referred to as a left-right direction, and a direction in which the short side portions extend is referred to as a front-rear direction.

As shown in FIGS. 2 and 3, the container body 2 includes a rectangular bottom portion 11 in a plan view and a rectangular tubular body portion 12 extending upward from the outer peripheral edge of the bottom portion 11. Further, at the upper end of the body portion 12, a container flange portion 13 is projected so as to extend outward in the radial direction over the entire circumference. The bottom portion 11, the body portion 12, and the container flange portion 13 are arranged coaxially with the container shaft O.

As shown in FIGS. 1 to 5, the frame body 3 has a rectangular annular frame flange portion 21 in a plan view and a rectangular tubular frame inner peripheral wall extending downward from the inner peripheral edge of the frame flange portion 21. A portion (frame peripheral wall portion) 22 and a rectangular tubular frame outer peripheral wall portion 23 extending downward from the outer peripheral edge of the frame flange portion 21 are provided. 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 shaft O.

The frame flange portion 21 is placed on the container flange portion 13. Further, a die-cutting opening 21A is formed on the front side portion and the rear side portion of the frame flange portion 21 to enable die-cutting when molding the mounting claw portion 23A described later. A plurality of die-cutting openings 21A are formed at intervals in the left-right direction.
At the lower end of the frame inner peripheral wall portion 22, a first locking protruding portion (first locking portion) 22A projecting inward in the radial direction is formed over the entire circumference. Further, the outer peripheral surface of the frame inner peripheral wall portion 22 is separated from the inner peripheral surface of the body portion 12 of the container body 2.

A plurality of mounting claws 23A projecting rearward are formed at the lower end of the front wall portion of the frame outer peripheral wall portion 23 at intervals in the left-right direction, and the lower end portion of the rear wall portion of the frame outer peripheral wall portion 23 is formed. Similarly, a plurality of mounting claw portions 23A projecting forward are formed at intervals in the left-right direction. These mounting claws 23A are formed at positions that overlap with the die-cut opening 21A in a plan view, and are locked to the container flange portion 13 from below.

The lid body 5 has a rectangular annular lid flange portion 31 in a plan view, a rectangular tubular lid peripheral wall portion 32 extending downward from the inner peripheral edge of the lid flange portion 31, and a lid peripheral wall portion 32 having an outer peripheral edge. The lid bottom wall portion 33, which is rectangular in plan view and is connected to the lower end of the lid, is provided. The lid flange portion 31, the lid peripheral wall portion 32, and the lid bottom wall portion 33 are arranged coaxially with the container shaft O.

The lid flange portion 31 is placed on the frame flange portion 21. Further, a knob portion 34 is provided at the central portion of the lid flange portion 31 in the left-right direction of the front side portion.
The front end position of the knob portion 34 is the same as the front end position of the front side portion of the frame flange portion 21, and protrudes slightly forward from the front end position of the front side portion of the frame flange portion 21. As described above, "the front end position of the knob portion 34 is equivalent to the front end position of the front side portion of the frame flange portion 21" means that the subject who is allowed to open the box-shaped container 1 such as an adult. It is possible to catch something that is difficult to catch with a finger, and some things that protrude slightly to some extent are included.

Further, the outer peripheral edge of the lid flange portion 31 is located radially inside the outer peripheral edge of the frame flange portion 21 in a plan view, except for the central portion in the left-right direction of the rear end portion. The central portion of the lid flange portion 31 in the left-right direction of the rear end portion protrudes rearward from the frame flange portion 21, and the lid outer wall portion 35 extending in the left-right direction extends to the rear end of this portion. It is extended downward. The lower end of the lid outer wall portion 35 is connected to the lower end of the rear wall portion of the frame outer peripheral wall portion 23 via a hinge 4.

The lid peripheral wall portion 32 extends radially inside the frame inner peripheral wall portion 22 along the frame inner peripheral wall portion 22, and the lower end of the lid peripheral wall portion 32 is below the lower end of the frame inner peripheral wall portion 22. positioned. Further, the outer peripheral surface of the lid peripheral wall portion 32 is separated from the inner peripheral surface of the frame inner peripheral wall portion 22. Further, among the front wall portions of the lid peripheral wall portion 32, the lower ends on both the left and right sides of the grip portion 34 project forward and downward with respect to the first locking protrusion 22A formed on the inner peripheral wall portion 22 of the frame. A pair of second locking protrusions (second locking portions) 32A that are locked from the above are formed.

Next, a method of using the box-shaped container 1 having the above configuration will be described.
First, for example, as shown in FIG. 6A, the outer surface of the front wall portion of the outer peripheral wall portion 23 of the frame and the inner surface of the front wall portion of the lid peripheral wall portion 32 are sandwiched in the front-rear direction by the thumb and index finger of one hand of the subject. .. At this time, the belly of the thumb is caught by the front end of the knob portion 34, and as shown in FIG. 6B, the knob portion 34 is rolled up starting from the rear end of the front side portion of the lid flange portion 31. Here, since the front wall portion of the lid peripheral wall portion 32 is held down by the index finger, when the thumb tries to pull up the knob portion 34 upward, the knob portion 34 is not the lower end but the upper end of the front wall portion of the lid peripheral wall portion 32. Attempts to rotate upward starting from. As a result, the grip portion 34 is more reliably rolled up starting from the rear end of the front side portion of the lid flange portion 31.

When sandwiching the front wall portion of the frame outer peripheral wall portion 23 and the front wall portion of the lid peripheral wall portion 32 in the front-rear direction, the front wall portion of the lid peripheral wall portion 32 is pushed forward with respect to the container body 2 to form a lid. The front side portion of the flange portion 31 may be displaced forward. As a result, the amount of protrusion of the grip portion 34 forward with respect to the front side portion of the frame flange portion 21 is increased, so that the finger of the subject can be easily hooked on the front end of the grip portion 34. In this way, when the front wall portion of the outer peripheral wall portion 23 of the frame and the front wall portion of the lid peripheral wall portion 32 are sandwiched in the front-rear direction, the front wall portion of the lid peripheral wall portion 32 is pushed forward with respect to the container body 2. The front end of the grip portion 34 does not have to protrude from the front end of the front side portion of the frame flange portion 21 before being pushed in.

When the picking portion 34 is rolled up, the contact area between the belly of the thumb and the lower surface of the picking portion 34 increases, and the picking portion 34 can be easily picked by the fingers. After that, by picking up the knob portion 34, as shown by a virtual line in FIG. 3, the entire lid body 5 is rotated around the hinge 4 with respect to the frame body 3 and pulled up.
In the process of pulling up the lid body 5, the front wall portion of the lid peripheral wall portion 32 elastically deforms rearward from the lower end of the front wall portion, so that the second locking protrusion 32A and the first locking portion 32A are locked. The locked state with the protruding portion 22A is released. In this way, the box-shaped container 1 is opened.

After appropriately taking out the contents in the opened box-shaped container 1, the lid 5 is rotated in the opposite direction around the hinge 4 with respect to the frame 3, and further, for example, the lid bottom wall 33 is pushed downward. , The second locking protrusion 32A and the first locking protrusion 22A are locked again. In this way, the box-shaped container 1 is closed.
On the other hand, even if a non-target person such as an infant who is not allowed to open the box-shaped container 1 tries to open the box-shaped container 1, the knob portion 34 is directed to the front end of the front side portion of the frame flange portion 21. Since it does not protrude sufficiently forward, it is restricted to roll up the grip portion 34 with a finger. Therefore, the non-target person is restricted from opening the box-shaped container 1.
As described above, the box-shaped container 1 is used.

As described above, according to the box-shaped container 1 according to the present embodiment, the grip portion 34 does not sufficiently project forward from the frame flange portion 21, and for the non-target person, the operation of hooking a finger on the grip portion 34 and pulling it up is performed. Since it is difficult to perform, it is restricted that the non-target person operates the picking portion 34. In particular, since the lid body 5 is not provided with an outer peripheral wall portion having a front wall portion unlike the conventional box-shaped container described above, the non-target person grasps the lid body 5 and unintentionally holds the container body 2. The possibility of opening can be reduced more reliably. On the other hand, the subject has a dexterous fingertip as compared with, for example, an infant, and can operate the picking portion 34 to open the box-shaped container 1. As a result, the target person can surely open the box-shaped container 1 while having the child-proof function in the box-shaped container 1.
Further, since the picking portion 34 is elastically deformable, the contact area between the picking portion 34 rolled up by the target person and the finger of the target person increases when the box-shaped container 1 is opened. As a result, the picking portion 34 becomes easy to operate, and the opening operability of the box-shaped container 1 with respect to the target person is improved.

Next, a second embodiment of the box-shaped container according to the present invention will be described with reference to the drawings. The embodiment described here has the same basic configuration as the above-described embodiment, and has another element added to the above-described embodiment. Therefore, in the following drawings, the same components as those in the above drawings are designated by the same reference numerals, and this description will be omitted.

As shown in FIGS. 7 and 8, the box-shaped container 100 according to the present embodiment includes a container body 2, a frame body 101, and a lid body 102.
As shown in FIGS. 8 to 11, a pair of leaf spring portions 104 projecting rearward are provided on the front wall portion of the frame inner peripheral wall portion 103 of the frame body 101. The pair of leaf spring portions 104 are formed on the front wall portion of the frame inner peripheral wall portion 103 at intervals on the left and right sides of the knob portion 105.

The upper end of the leaf spring portion 104 is connected to the frame flange portion 21, and is curved so as to go downward from the front to the rear. A first locking protrusion 104A that protrudes rearward is formed at the lower end of the leaf spring portion 104. Further, a die-cut notch 103A for molding the leaf spring portion 104 is formed in a portion of the front wall portion of the frame inner peripheral wall portion 103 corresponding to a position where the leaf spring portion 104 is provided in the left-right direction. ..

At the lower end of the lid peripheral wall portion 106 of the lid 102, a pair of second locking protrusions 106A that lock from below with respect to the first locking protrusion 104A formed on the leaf spring portion 104 are formed. There is.
The front side portion of the lid flange portion 107 is recessed from the front side portion of the lid flange portion 31 in the first embodiment. Further, the front end position of the knob portion 105 provided on the lid flange portion 107 is the same as the front end position of the front side portion of the frame flange portion 21, but is higher than the front end position of the front side portion of the frame flange portion 21. It is located slightly behind. The front wall portion of the lid peripheral wall portion 106 is also recessed from the front wall portion of the lid peripheral wall portion 32 in the first embodiment.

The method of using the box-shaped container 100 having the above configuration is also the same as the method of using the box-shaped container 1 according to the first embodiment described above.
As shown in FIG. 12A, the front wall portion of the outer peripheral wall portion 23 of the frame and the front wall portion of the lid peripheral wall portion 106 are sandwiched in the front-rear direction with the thumb and index finger of one hand to resist the rearward urging force of the leaf spring portion 104. Then, the front wall portion of the lid peripheral wall portion 106 is pushed forward. As a result, the lid flange portion 107 is elastically displaced forward, and the knob portion 105 projects slightly forward from the front end of the frame flange portion 21. At this time, the amount of protrusion of the grip portion 105 from the front end of the frame flange portion 21 is substantially the same as the amount of protrusion of the grip portion 34 from the frame flange portion 21 in the first embodiment described above.
After that, as shown in FIG. 12B, the box-shaped container 100 is opened in the same manner as in the box-shaped container 1 according to the first embodiment described above.

As described above, the box-shaped container 100 according to the present embodiment also has the same effect as the box-shaped container 1 according to the first embodiment described above, but the front wall portion of the lid peripheral wall portion 106 is pushed forward to push the leaf spring portion 104. By elastically deforming the grip portion 105, the grip portion 105 is elastically displaced forward, so that the subject can easily operate the grip portion 105. Then, since the grip portion 105 also retracts with the restored displacement of the leaf spring portion 104, it is possible to more reliably regulate the opening of the box-shaped container 100 by the non-target person.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
