JP7009035B2 - Box-shaped container - Google Patents

Description

The present invention prevents the lid from being opened by, for example, an infant, a patient with dementia, etc. who does not allow the lid to be opened (hereinafter referred to as a subject), and a person other than the subject (hereinafter referred to as a non-target person). ) Refers to a box-shaped container having a child resistance function that allows the lid to be opened.

Many of the conventional containers have a simple fitting structure so that the lid can be removed immediately when the user wants to use the container, and many of them focus on the ease of removing and attaching the lid (for example, Patent Document 1). reference). However, since the emphasis was only on the ease of removing and attaching the lid in this way, as a result, anyone can easily remove the lid by simply pulling the lid, and the contents can be taken out. Has become free to do.

Under normal usage conditions where the user fully understands the characteristics of the contents to be stored or filled, such ease of removal of the lid is convenient and has no problem, a very desirable form. Is. However, there is a concern that the lid can be easily removed even by a person who does not fully understand the characteristics of the contents to be stored or filled.

That is, it is possible that the subject handles the contents without understanding the degree of danger of the contents and carelessly removes the lid of the container to touch the contents or accidentally swallow the contents.
In order to deal with such a problem, it is required to impart a function that cannot be easily removed by the subject, that is, a so-called child resistance function, to the container to be filled or the lid thereof. The container having the child resistance function can be removed, for example, while the conventional container lid can be removed by simply pulling the lid in the direction in which the lid and the container body are separated from each other, whereas the lid is simply pulled. The lid body cannot be removed only by the operation, and an operation different from pulling the lid body before or at the same time is performed on the lid body or the like, thereby removing the lid body.

The operation performed on the lid or the like for the child resistance function is not too complicated as compared with the operation of removing the lid on the conventional closing tool, and for non-target persons, the operation of removing the conventional lid is not performed. It is preferable that the ease is sufficiently ensured and the removal of the lid can be prevented against the opening operation by the subject.

Further, the other means of the present invention is obtained by adding a means that a plurality of locking mechanisms are provided to the main means of the present invention.
In the above means, the effectiveness of the child resistance function can be enhanced by putting all of the plurality of lock functions in the locked state. Also, when used by non-target persons, only a part of the locking mechanism can be locked and the remaining locking mechanism can be used in the unlocked state, so it is a convenient box-shaped container. can do.

Further, in the other means of the present invention, at least two of the plurality of locking mechanisms are provided in the above means at the positions of both corners of the inner frame portion and the outer frame portion located on the opposite side of the hinge. It is the addition of the means that it has been done.
In the above means, by arranging the lock function at both corners separated by a distance, it is necessary for the subject to release the lock mechanism by using both hands, so that it can be operated dexterously. It is possible to provide an advanced child resistance function for those who are not good at it.

Further, the other means of the present invention is set to a locked state by engaging any of the above means with the tip of the first locking portion and the tip of the second locking portion that overlap each other. This is with the addition of a means that the lock is set to the unlocked state when the case is released.
In the above means, it is possible to easily set the locked state or the unlocked state by performing an operation of twisting the tip of the first locking portion and the tip of the second locking portion while pinching them with a fingertip. can.

Further, the other means of the present invention is obtained by adding the means that the container body, the inner frame portion, and the lid portion having the outer frame portion are all integrally formed to any of the above means.
In the above means, for example, a thermoforming molding method can be used, so that a box-shaped container can be easily formed, and as a result, the manufacturing cost can be reduced.

Since the present invention has the above-mentioned configuration, the following effects are obtained.
In the present invention, it is possible to realize a child resistance function that prevents the subject from removing the lid.
Further, since the conventional lid can be easily removed, it can be a box-shaped container having excellent operability for non-target persons.

FIG. 3 is a partial cross-sectional view taken along the line XI-XI of FIG. 10A showing a locked state.

The object to be stored in the box-shaped container of the present invention is, for example, a content formed in the form of powder, a content obtained by forming a liquid or powder covered with a film into a substantially ball shape, or a solid content. , This content includes, for example, detergents and chemicals that the subject does not want to touch.
First, the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
As shown in FIGS. 1 to 3, the box-shaped container shown in the first embodiment includes a container body 1 and a lid 10 formed by, for example, injection molding a synthetic resin material.
The container body 1 is a bottomed square cylindrical container in which a flange 3 is provided around the upper opening end portion 2, and the contents can be accommodated therein.
The lid 10 has an inner frame portion 11 formed in a U-shaped cross section and arranged by fitting on the flange 3, and an outer frame portion 11 formed in the same U-shaped cross section and able to be fitted to the inner frame portion 11. It has a lid portion 10A having a frame portion 12 and a top wall 13 recessed inside the outer frame portion 12, and a thin-walled hinge 14 connecting between the inner frame portion 11 and the outer frame portion 12. The lid portion 10A is configured to be rotatable (openable / closable) with respect to the outer frame portion 12 around the hinge 14.

As shown in FIG. 1, undercut-shaped fitting pieces 11a are projected downward at six positions around the inner frame portion 11, and the inner frame portion 11 is assembled and fitted to the flange 3. When they are combined, each fitting piece 11a can get over the flange 3 downward and lock the flange 3 inseparably (see FIG. 3).
Further, as shown in FIG. 1, a locking piece 15a that functions as a first locking portion 15 at a position on the inner frame portion 11 opposite to the hinge 14 and near the center line Ow in the width direction. Is formed toward the outside. The locking piece 15a is formed in a thin wall shape, and the tip portion thereof is configured to be elastically deformable in the thickness direction.

Similarly, at a position on the outer frame portion 12 opposite to the hinge 14 and near the center line Ow in the width direction, a locking piece 16a functioning as a second locking portion 16 faces outward. It is formed. The locking piece 16a is also formed in a thin wall shape, and the tip portion thereof is configured to be elastically deformable in the thickness direction. The locking piece 15a that functions as the first locking portion 15 and the locking piece 16a that functions as the second locking portion 16 are formed so as to be axially symmetric with the center line Ow interposed therebetween (FIG. FIG. See 2A).

As shown in FIGS. 2 and 3, when the lid portion 10 is rotated around the hinge 14 and the outer frame portion 12 is assembled and fitted on the inner frame portion 11, the open end portion 2 of the container body 1 is fitted. Can be set to a closed state in which the lid 10 is closed by the top wall 13. In the state immediately after the closure, as shown in FIG. 3B, the tip of the locking piece 16a (second locking portion 16) on the outer frame portion 12 side is the locking piece 15a (first engagement) on the inner frame portion 11 side. It is in an unlocked state that overlaps the tip of the stop 15). Then, from this state, for example, the tip of the locking piece 15a and the tip of the locking piece 16a are pinched between the thumb and the index finger, and the fingertip in the pinched state is rotated and twisted. As shown, it is possible to set the locked state in which the tip end portion of the locking piece 15a on the inner frame portion 11 side overlaps and engages with the tip end portion of the locking piece 16a on the outer frame portion 12 side.

To release the locked state, the tip of the locking piece 15a (first locking portion 15) and the tip of the locking piece 16a (second locking portion 16) are again picked, and the direction is opposite to that at the time of locking. This can be achieved by twisting and disengaging the tip of the locking piece 16a on the outer frame portion 12 side and the tip of the locking piece 15a on the inner frame portion 11 side.

As described above, in the present invention, it is necessary to twist the locking piece 15a (first locking portion 15) and the locking piece 16a (second locking portion 16) while picking them, but the infant is not particularly dexterous. Since I am not good at the detailed operation of twisting while picking with my fingertips, it is difficult to easily open the lid. Therefore, it is possible to fully exert the child resistance function that prevents the subject from opening the lid.
On the other hand, for non-target persons, the operation of twisting while picking with the fingertip is not a pain, so it is possible to easily set the locked state and the unlocked state by performing the above operation. Excellent operability can be maintained.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.
The basic configuration and effect of the box-shaped container shown in the second and examples are the same as those in the first embodiment, and only the configuration of the locking mechanism is different. Therefore, in the following description, the same member will be described with the same reference numerals, focusing on the lock mechanism, which is different from the first embodiment.

As shown in FIG. 4, in the box-shaped container shown in the second embodiment, the inner frame in which the locking piece 15b (first locking portion 15) constituting one of the locking mechanisms is located on the opposite side facing the hinge 14. The outer frame portion 12 is arranged on both corners of the portion 11 so as to face outward, and the locking piece 16b (second locking portion 16) constituting the other side of the locking mechanism is also located on the opposite side facing the hinge 14. It differs from the first embodiment in that the locking mechanism is arranged in the center in the width direction in that it is arranged outward at both corners.

As shown in FIGS. 5A and 5B, in the configuration of the second embodiment, the inner frame portion 12 is fitted on the inner frame portion 11 by rotating the lid 10 around the hinge 14. The tip of the locking piece 15b (first locking portion 15) of the frame portion 11 and the tip of the locking piece 16b (second locking portion 16) of the outer frame portion 12 are engaged with each other at the positions of both corners. It is possible to put it in a locked state by making it lock.

On the other hand, since the locking mechanism is provided at the positions of both corners separated from each other, it is necessary to operate the locking mechanism of both corners with both hands in order to release the locked state at the same time, or the locking mechanism of one corner must be operated. After releasing, it is necessary to perform two operations of releasing the locking mechanism of the other corner. In particular, the subject is not good at operating one lock mechanism with his right hand and the other lock mechanism with his left hand at the same time. Further, when a plurality of lock mechanisms are provided, even if some of the lock mechanisms are released, it is possible to make it difficult to open the lid as long as the remaining lock mechanisms are in the locked state. Therefore, it is possible to enhance the child resistance function that prevents the subject from opening the lid.
On the other hand, for non-target persons, it is easy to operate both lock mechanisms by using both hands at the same time, and even if a plurality of lock mechanisms are provided, they can be operated one by one. Therefore, it is possible to easily set the locked state and the unlocked state, and it is possible to maintain excellent operability.

Next, a third embodiment of the present invention will be described with reference to FIGS. 6 and 7.
The basic configuration and effect of the box-shaped container shown in the third embodiment are the same as those in the first embodiment, and only the configuration of the locking mechanism is different. In the following description, the same member will be described with the same reference numerals, focusing on the locking mechanism, which is different from the first embodiment.
As shown in FIG. 6, in the box-shaped container shown in the third embodiment, the inner frame portion 11 is first engaged at the center position in the width direction on the inner frame portion 11 on the opposite side facing the hinge 14. The locking pieces 15a functioning as the stopping portions 15 are arranged outward, and the locking pieces 15b also functioning as the first locking portions 15 are arranged outward at the positions of the both corners. Similarly, regarding the outer frame portion 12, the locking piece 16a functioning as the second locking portion 16 is directed outward at the center position in the width direction on the outer frame portion 12 on the opposite side facing the hinge 14. Locking pieces 16b, which are also arranged and also function as second locking portions 15, are arranged outward at the positions of both corners. The lock mechanism provided at the center position has the same configuration as that of the first embodiment, and the lock mechanism provided at both corners has the same configuration as that of the second embodiment.

In the third embodiment, as shown in FIGS. 7A and 7B, in a state where the lid portion 10A is rotated around the hinge 14 and the outer frame portion 12 is fitted on the inner frame portion 11, the center portion is centered. As for the locking mechanism, as in the first embodiment, while pinching the tip of the locking piece 15a on the inner frame portion 11 side and the tip of the locking piece 16a on the outer frame portion 12 side in an overlapping state with a fingertip. By twisting, it is possible to set the locked state in which both are engaged. Regarding the locking mechanism arranged at both corners, the locking piece 15b of the inner frame portion 11 and the locking piece 16b of the outer frame portion 12 are engaged with each other at the positions of both corners, as in the second embodiment. By doing so, it is possible to put it in a locked state. Further, the lock mechanism can be released in the unlocked state by performing the same operation as in the first embodiment or the second embodiment.

In the third embodiment, when all of the locking mechanisms provided at the plurality of positions (three places in the third embodiment) are set to the locked state, the operation of releasing the locked state can be made more complicated. Moreover, while the central lock mechanism requires the operation of pinching and twisting with the fingertips, the lock mechanism of both corners needs to be operated with both hands, or one of them needs to be operated in two steps. Compared with the first embodiment or the second embodiment, the child resistance function for preventing the lid from being opened by the subject can be further improved.

However, it is complicated even for a non-target person to require operation for all of the lock mechanisms provided at a plurality of positions (three places in the third embodiment). Therefore, when used by a non-target person who does not need the child resistance function, the lock mechanism at both corners should not be used while maintaining the non-locked state at all times, and only the central lock mechanism should be operated. Since it is possible to operate the central lock mechanism with one hand, it is possible to maintain comfortable operability.
That is, the box-shaped container of the third embodiment can be used differently between the target person and the non-target person.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. 8 to 11.
The box-shaped container shown in the fourth embodiment has a configuration in which the container body 1 and the lid portion 10A are integrally connected via a hinge 14 formed in a thin wall shape, and for example, a synthetic resin sheet (raw fabric) is used. It is integrally formed by a thermoforming molding method (sheet molding method) in which the gap between the mold and the sheet is evacuated by heating and softening, and the sheet is closely cooled to the mold and drawn.

The container body 1 is a bottomed cylindrical container having an opening edge 2 at the upper side. The inner frame portion 11 having a U-shaped cross section is arranged in a circumferential shape along the opening edge portion 2, and is formed at both corners of the inner frame portion 11 on the opposite side facing the hinge 14 as in the second embodiment. Each of the locking pieces 15b (first locking portion 15) constituting the locking mechanism is formed.
The lid portion 10A has an outer frame portion 12 that can be fitted to the inner frame portion 11 on the container body 1 side, and a recessed top wall 13 is continuously provided at the lower end inside the outer frame portion 12. There is. Then, as in the second embodiment, locking pieces 16b (second locking portions 15) constituting the locking mechanism are formed outward at both corners of the outer frame portion 12 on the opposite side facing the hinge 14. Has been done.

Then, as shown in FIG. 10, the lid portion 10A is rotatably (openable / closable) supported with respect to the container body 1 via the hinge 14, and the lid portion is placed on the inner frame portion 11 on the container body 1 side. By fitting the outer frame portion 12 on the 10A side, the lid can be closed (see FIGS. 9A, 9B and 11). Immediately after the lid is closed, the locking mechanism is in an unlocked state in which the locking piece 15b (first locking portion 15) is simply placed on the locking piece 16b (second locking portion 15). It is in.
Then, as shown in FIG. 11, as in the second embodiment, the tip portion of the locking piece 16b (second locking portion 15) and the locking piece 15b (second locking portion 15b) constituting the locking mechanism are located at both corners. By engaging each of the tips of the 1 locking portions 15), it is possible to set the locked state to prevent the lid portion 10A from opening.

Also in this fourth embodiment, since both lock mechanisms are located at both corners separated from each other, the lock mechanism of both corners can be operated with both hands or one corner can be locked in order to release the locked state at the same time. Since it is necessary to release the lock mechanism at the other corner after releasing the mechanism, the operation is complicated. Therefore, similarly to the above, since the subject cannot be easily opened, it is possible to provide a child resistance function for preventing the subject from opening the lid.

Further, as shown in FIGS. 9A and 9B showing the closed state, in the state where the outer frame portion 12 on the lid portion 10A side is fitted on the inner frame portion 11 on the container body 1 side, the inner frame portion 11 The external dimensions are formed to be one size larger than the outer diameter dimension of the outer frame portion 12, and the inner frame portion 11 on the lower side is configured to protrude outward from the outer frame portion 12 on the upper side. .. In this configuration, the finger of the subject holding the box-shaped container can be made difficult to catch on the inner frame portion 11, and from this point as well, the child resistance function for preventing the subject from opening the lid can be further improved. Is.

Even in the configuration in which the container body 1 and the lid portion 10A are integrally connected via the hinge 14, the locking mechanism is not limited to the second embodiment (configuration provided at both corners), and the first embodiment is described above. Similarly, the lock mechanism can be provided only in the center, or the lock mechanism can be provided at a plurality of positions such as three places as in the third embodiment.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.

For example, in the first to third embodiments described above, the case where the container body 1 and the lid portion 10A are composed of different members has been described, but the present invention is not limited to this, and the container body 1 and the container body 1 are described. The structure may be such that the lid portion 10A and the lid portion 10A are integrally molded.

Further, in each of the above embodiments (excluding the fourth embodiment), the case where the container body 1 is made of synthetic resin has been described, but the container body 1 in the cases of the first to third embodiments is made of paper or metal. It may be made of other materials such as made of glass, made of glass, and made of pottery.

Further, in the third embodiment, the configuration in which the lock mechanism is arranged at three positions is shown and described, but the number of the lock mechanisms arranged is not limited to this.

The present invention can be used in a wider range of applications in the field of containers that require a child resistance function.
