Description

  The present invention relates to a box-type container having a lid, and more particularly to a box-type container with a lock mechanism having a child resistance function that prevents an infant or the like from opening the lid unnecessarily.

  Many conventional containers have a simple fitting structure so that the lid can be removed immediately when it is desired to be used, and many have focused on ease of removal and mounting of the lid (for example, Patent Document 1). reference). However, since the emphasis was placed only on the ease of removing and attaching the lid as described above, as a result, anyone can easily remove the lid by simply pulling the lid, and the contents can be taken out. Can be done freely.

  In normal use situations where the user fully understands the characteristics of the contents to be stored or filled, the ease of removing such a lid is convenient and has no problem and is a very desirable form. It is. However, there is a concern that even a person who cannot fully understand the characteristics of the contents to be stored or filled can easily remove the lid.

That is, for example, an infant or the like may imitate the behavior of surrounding adults and remove the lid of the container and mischief the contents without understanding the danger level of the contents.
In order to cope with these problems, it is required to provide a function that cannot be easily removed by an infant or the like, that is, a so-called child resistance function, to a container to be filled or a lid thereof. The container having the child resistance function can be removed by simply pulling the lid body in the direction of separating the lid body and the container body, while the container lid body according to the prior art is simply pulled. The lid body is not removed only by the operation, and the lid body or the like is subjected to an operation different from that of pulling the lid body before or simultaneously with the lid body, thereby removing the lid body.

  The operation performed on the lid for the child resistance function is not too complicated compared to the lid removing operation in the conventional lid, and the ease of removing the conventional lid is sufficiently secured. In addition, it must be able to prevent the removal of infants by mischief.

When the slide plate 31 moves in the other end (left end) direction, the pressing protrusion 34 can be inserted into the outer second through hole 26 (see FIG. 12B).

Next, the operation of the box-shaped container A will be described.
FIG. 10 is a sectional view taken along line XX of FIG. 2 showing the first locking mechanism, in which A is in a locked state, B is in a unlocked state, and C is in an unlocked state after being released. 11 shows the second locking mechanism, A is a sectional view taken along the line XIa-XIa in FIG. 2 showing the locked state, B is a sectional view taken along the line XIb-XIb in FIG. 2 showing the unlocked state, and C is after being released. FIG. 3 is a cross-sectional view taken along the line XIb-XIb in FIG. FIG. 12 is a cross-sectional view taken along the line XII-XII of FIG. 2 showing the third lock mechanism, where A is a locked state, B is in a unlocked state, and C is an unlocked state after release.

By fitting the inner frame portion 11 of the inner lid 10 to the flange 3 of the container body 1 and further fitting the outer frame portion 21 of the outer lid 20 from above, the box-shaped container A is set in a closed state. (See FIG. 1).
The slide plate 31 is slid and set to a state (locked state) where one end (right end) of the slide plate 31 is moved to a position where it abuts on the inner wall portion 21a of the outer lid 20.
In this state, as shown in FIG. 10A, at the position of one end (right end) of the box-shaped container A, the inner through-hole in which the locking projection 33 provided at one end (right end) of the slide plate 31 is in communication. 13 and the outer first through hole 25. Then, the locking piece 33a engages with a stepped portion S formed between the upper wall of the inner through hole 13 and the upper wall of the outer first through hole 25, and the locking projection 33 is connected to the inner through hole 13 and It is in a state where it cannot be removed from the outer first through hole 25. Therefore, one end (right end) of the box-shaped container A is set in a locked state in which the outer frame portion 21 and the inner frame portion 11 are assembled so as not to be separable and the opening of the outer lid 20 is prevented. Thus, the locking piece 33a, the inner through hole 13 and the outer first through hole 25 constitute a first lock mechanism that prevents the outer lid 20 from being opened at one end (right end) of the box-shaped container A. .

  11A, at the position of the front end of the box-shaped container A, the outer frame side guide slot 24 of the outer frame portion 21 and the inner frame of the inner frame portion 11 in which the guide ribs 32 of the slide plate 31 are in communication with each other. The outer frame portion 21 and the inner frame portion 11 are set in a locked state in which the outer frame portion 21 and the inner frame portion 11 are assembled so as not to be separated by being inserted into and engaged with both of the side guide long holes 16. As described above, the guide rib 32, the outer frame side guide slot 24, and the inner frame guide slot 16 constitute a second lock mechanism that prevents the outer lid 20 from being opened at the front end of the box-shaped container A.

  Further, as shown in FIG. 12A, at the position of the other end (left end) of the box-shaped container A, the locking convex portion 14b provided on the biasing member 14 of the inner wall portion 11a on the inner frame portion 11 side is biased. In this state, the locking concave portion 27 provided on the back surface of the inner wall portion 21a on the outer frame portion 21 side is elastically pressed, and the locking convex portion 14b and the locking concave portion 27 are engaged. Therefore, the other end (left end) of the box-shaped container A is set in a locked state in which the outer frame portion 21 and the inner frame portion 11 are assembled so as not to be detached. Thus, the locking projection 14b provided on the biasing member 14 on the inner frame portion 11 side and the locking recess 27 on the outer frame portion 21 side are the outer lid 20 at the other end (left end) of the box-shaped container A. The 3rd lock mechanism which prevents opening of the is constituted.

  Thus, in the box-shaped container A of the present invention, the inner lid 10 is formed at the right end, the front end, and the left end excluding the rear end having the hinge 40 by bringing the slide plate 31 into the locked state in which the slide plate 31 is moved to the most end (right end). The box-shaped container A cannot be opened by locking between the outer lid 20 and the outer lid 20. Therefore, the childhood etc. cannot open the box-shaped container A easily, and as a result, removal by mischief can be prevented.

Next, an operation for taking out the contents from the box-shaped container A will be described.
As shown in FIG. 10B, at the position of the front end of the box-shaped container A, one end (right end) of the slide plate 31 is pressed downward to bend and deform, and the engagement between the locking piece 33a and the stepped portion S is released. . Next, as shown in FIG. 10C, the slide plate 31 is slid in the other end (left end) direction (the arrow direction in the figure), and the locking projection 33 is removed from the inner through hole 13 and the outer first through hole 25. Thus, the locked state of the first lock mechanism is released (non-locked state). Furthermore, the window part 22a currently formed in the top wall 22 of the outer cover 20 can be exposed by moving the slide board 31 toward the other end (left end) direction continuously (refer FIG. 2). Therefore, the contents stored in the container main body 1 can be taken out little by little through the window portion 22a.

Next, the slide plate 31 is slid and moved to a position on the other end (left end) side where the other end (left end) of the slide plate 31 contacts the inner wall portion 21 a of the outer lid 20. Then, at the position of the front end of the box-shaped container A, the guide rib 32 of the slide plate 31 reaches the position in the open portion 17 (see FIG. 11B) from the position in the inner frame side guide slot 16 (see FIG. 11A). Since the engagement between the guide rib 32 and the inner frame side guide slot 16 is released, the second lock mechanism can be brought into an unlocked state.
Further, as shown in FIGS. 12A and 12B, when the other end (left end) of the slide plate 31 comes into contact with the inner wall portion 21a of the outer lid 20, the pressing protrusion 34 is inserted into the outer second through hole 26, and the back surface thereof. Since the locking projection 14b located on the side is pushed in and the locking projection 14b and the locking recess 27 are disengaged, the third locking mechanism can be brought into an unlocked state.

Thus, by moving the slide plate 31 to the other end (left end) side, all of the first lock mechanism, the second lock mechanism, and the third lock mechanism can be released.
Therefore, as shown in FIGS. 10C, 11C, and 12C, when the outer lid 20 is rotated about the hinge 40 provided at the rear end, the fitting between the outer frame portion 21 and the inner frame portion 11 is released. Therefore, the outer lid 20 can be in an open state (see the broken line in FIG. 3, FIG. 4, or FIG. 9). Therefore, many contents can be taken out through the opening 12 of the inner frame portion 11 at a time.

  As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.

  For example, in the above embodiment, the configuration in which the outer lid 20 has the window portion 22a is shown and described. However, the configuration may be such that the window portion 22a is not provided, and the contents can be taken out only by the opening operation of the outer lid 20. good.

  In the above embodiment, the inner lid 10 and the outer lid 20 are shown as being integrally connected via the hinge 40. However, the configuration without the hinge, that is, the inner lid 10 and the outer lid 20 are separated. The structure which consists of members may be sufficient.

  In the above-described embodiment, the configuration having all of the first to third locking mechanisms as the locking mechanism has been described. However, a configuration having at least one locking mechanism may be used.

  Moreover, in the said Example, although the right end which has the window part 22a was prescribed | regulated as one end and the left end of the opposite side was prescribed | regulated as the other end, even if it is the structure which uses one end as a left end and the other end opposite to it is a right end. good.

  The box-type container with a lock mechanism of the present invention can be used in a wider area in the field of a box-type container having a lock mechanism that regulates the opening of the lid.
