As a result, the inner plate can be pushed up via the push-up member, and the elastic locking portion is pushed apart from the outer circumferential wall of the inner plate using the lifting force of the inner plate, and the elastic locking portion is The engagement with the circumferential groove can be released. As a result, it is possible to remove the inner tray from the inner container.

Japanese Patent Application Publication No. 2005-137439

However, in conventional compact containers, the force used to push up the inner plate by the push-up member is used to release the engagement between the elastic locking portion and the circumferential groove. In some cases, the inner plate cannot be removed, and there is room for improvement in the operability of removing the inner plate.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a compact container with improved operability for removing the inner plate.

(1) The compact container according to the present invention includes an inner container that contains a content, an inner container that has a peripheral wall and a bottom wall, and that accommodates the inner container in a removable manner with the inner container facing upward, and a container that accommodates the inner container. and an outer container in which an operation hole is formed, the inner container being integrally formed with the inner container via a rotation shaft and disposed along the peripheral wall and the bottom wall. An operation piece is provided, the rotation shaft is arranged along a line of connection between the peripheral wall and the bottom wall, and the operation piece is arranged along the bottom wall so as to be able to be pushed up through the operation hole. and a push-up piece that is rotatable upward around the rotation axis, and an engaged portion that is arranged along the peripheral wall and formed on the side wall of the inner plate. an engagement piece having an engagement portion that engages with the operation piece, the operation piece having an outer shape formed by a first slit hole formed in the peripheral wall and a second slit hole formed in the bottom wall, The rotation shaft is partitioned from the peripheral wall by the first slit hole, is partitioned from the bottom wall by a first rotation piece disposed along the peripheral wall, and by the second slit hole, and is attached to the bottom wall. a second rotating piece disposed along the inner plate, and the push-up piece can come into contact with the bottom wall of the inner tray from below as it rotates upward. The engagement piece rotates about the rotation axis in conjunction with the rotation of the push-up piece so as to separate from the side wall of the inner plate, and engages the engaged portion with the engagement piece. release the engagement with the section.

According to the compact container according to the present invention, during normal use, the engaging portion of the engaging piece formed on the inner container engages with the engaged portion of the inner plate, so that This makes it difficult for the inner plate to come off. Therefore, the contents in the inner tray can be easily wiped off, for example, and ease of use can be improved.
On the other hand, when replacing the inner tray after the contents are used up, for example, the push-up piece is pushed upward with a fingertip or the like through an operation hole formed in the outer container. Thereby, the push-up piece can be pushed upward while rotating the entire operation piece around the rotation axis. Therefore, an upward external force can be applied to the bottom wall of the inner plate via the push-up piece.

Further, since the operation piece itself rotates, as the push-up piece rotates upward, the engagement piece rotates around the rotation axis so as to separate from the side wall of the inner tray. Thereby, the engaging part can be separated from the engaged part, and the engagement between the engaging part and the engaged part can be released. Therefore, relative movement of the inner plate with respect to the inner container can be allowed. Therefore, by using the push-up piece, the inner plate can be pushed upward relative to the inner container, and the inner plate can be easily removed from the inner container. As a result, the used inner plate can be replaced, and, for example, a new inner plate filled with contents can be set.
In particular, by rotating the operation piece around the rotation axis, the push-up operation of the inner plate using the push-up piece and the disengagement operation of the inner plate using the engagement piece can be performed simultaneously in a series of operations. Therefore, for example, the inner plate can be reliably removed with a single touch, and the operability of removing the inner plate can be improved.
Furthermore, when the push-up piece is pushed up and the entire operation piece is rotated around the rotation axis, the push-up piece and the engagement piece are rotated about the connection line between the peripheral wall and the bottom wall. It can be displaced as follows. Therefore, it is possible to prevent the push-up piece and the engagement piece from rotating excessively. Therefore, there is no need to secure a large rotation space around the operating piece, which can contribute to making the compact container smaller and thinner.
Further, the outer shape of the operating piece is formed by the first slit hole formed in the peripheral wall and the second slit hole formed in the bottom wall. That is, the operating piece is formed by partially partitioning a portion of the peripheral wall and the bottom wall by the first slit hole and the second slit hole. Therefore, the operation piece can be integrally formed to fit within the basic shape of the inner container, and the presence of the operation piece does not cause problems such as an increase in the external size or thickness of the inner container. Therefore, it can contribute to making the compact container itself smaller and thinner.
Further, when the push-up piece is pushed up, the entire operation piece can be rotated around the rotation axis while twisting and deforming the rotation axis itself, which has an L-shaped cross section.

(2) The first rotating piece has an upward protrusion amount P1 from the upper surface of the second rotating piece that satisfies T2≦P1≦1.5T2 with respect to a thickness T2 of the second rotating piece. It may be formed to satisfy the relationship.

In this case, since the upward protrusion amount P1 of the first rotating piece is at least the thickness T2 of the second rotating piece, the strength of the rotating shaft against stress in the vertical direction can be improved. Therefore, the rotating shaft itself can be stably torsionally deformed, and the inner plate can be appropriately pushed up. Furthermore, it is possible to ensure the necessary strength when setting the inner plate.
Moreover, since the upward protrusion amount P1 of the first rotating piece is set to be 1.5 times or less than the thickness T2 of the second rotating piece, the rotating shaft itself is prevented from being easily torsionally deformed. be able to.

( 3 ) The second rotating piece has a protrusion amount P2 from the inner surface of the first rotating piece into the inner container such that T1≦P2≦1 with respect to a thickness T1 of the first rotating piece. It may be formed to satisfy the relationship of .5T1.

In this case, since the amount of protrusion P2 of the second rotating piece into the inner container is at least the thickness T1 of the first rotating piece, the strength of the rotating shaft against horizontal stress can be improved. . Therefore, when the operation piece is pushed up, the rotation shaft itself can be prevented from being deformed to swing along the plane of the bottom wall of the inner container, and the inner tray can be pushed up appropriately. be able to. Furthermore, since it is possible to suppress the swinging of the operating piece along the plane of the bottom wall of the inner container, it is possible to ensure the engagement between the engaged part and the engaged part, and to increase the engagement force (fitting force). Easy to adjust.
Moreover, since the upward protrusion amount P2 of the second rotating piece is set to be 1.5 times or less than the thickness T1 of the first rotating piece, the rotating shaft itself is prevented from being easily torsionally deformed. be able to.

According to the compact container according to the present invention, the operability of removing the inner plate can be improved, and the inner plate can be replaced easily and smoothly.

Further, a portion of the second slit hole 70 surrounded by the first linear slit 71, the pair of second linear slits 72, and the pair of third linear slits 73 mainly functions as the push-up piece 52.
Further, a portion surrounded by the pair of third linear slits 63 in the first slit hole 60 and the pair of third linear slits 73 in the second slit hole 70 mainly functions as the rotation axis 51.

In particular, the third linear slit 63 in the first slit hole 60 and the third linear slit 73 in the second slit hole 70 are formed so as to overlap at least in the front-rear direction L1 when viewed in plan from the container axis O direction. There is. More preferably, the third linear slit 63 in the first slit hole 60 and the third linear slit 73 in the second slit hole 70 are located at a position in the front-rear direction L1 over the entire length in a plan view when viewed from the container axis O direction. It is preferable that they be formed so that they are at the same position, so that they are arranged in parallel to the left-right direction L2 over the entire length.

It is possible to disengage the engagement protrusion 54 and the engagement recess 30 by disengaging the engagement protrusion 54 from the engagement recess 30.

As shown in FIGS. 1 and 5, a pair of rotation shafts 51 are provided at intervals in the front-rear direction L1, and are provided along a continuous line N between the internal bottom wall 11 and the left internal peripheral wall 12. It is located.
The rotation shaft 51 is partitioned from the inner circumferential wall 12 by the third linear slit 63 in the first slit hole 60, so that the first rotation piece 51a arranged along the inner circumferential wall 12 and the second slit hole 70 By being partitioned from the internal bottom wall 11 by the third linear slit 73 in , it is formed into an L-shaped cross section having a second rotating piece 51b arranged along the internal bottom wall 11.

As shown in FIG. 6, the first rotating piece 51a has an upward protrusion amount P1 from the upper surface of the second rotating piece 51b, with respect to the thickness T2 of the second rotating piece 51b, T2≦P1 It is formed to satisfy the relationship ≦1.5T2.
Further, the second rotating piece 51b has a protrusion amount P2 from the inner surface of the first rotating piece 51a toward the right side, that is, toward the inside of the inner container 10, which is T1 with respect to the thickness T1 of the first rotating piece 51a. It is formed to satisfy the relationship ≦P2≦1.5T1.

(Function of compact container)
Next, a case will be described in which the compact container 1 configured as described above is used.
In this case, the push piece 40 is operated to release the locked state (closed state) of the lid body 5. Specifically, the operation wall portion 41 shown in FIGS. 1 and 3 is pressed rearward to move the entire push piece 40 rearward. Thereby, the release protrusion 42 can be moved rearward while being elastically deformed along the inclined surface 16a of the guide wall portion 16, and the second engagement protrusion 32 can be pushed up from below and separated from the first engagement protrusion 17. be able to.
Thereby, the engagement between the first engagement protrusion 17 and the second engagement protrusion 32 can be released, and the lid body 5 can be opened.

Next, by rotating the entire lid 5 around the hinge portion 4, the lid 5 can be opened rearward as shown in FIG. 1, and the lid 5 is separated from the container body 3. can be done. Thereby, the contents W in the inner tray 2 can be used while being wiped off, for example.
In particular, during such normal use, as shown in FIG. Therefore, it is possible to make it difficult for the inner plate 2 to come off from inside the inner container 10. Therefore, the contents W in the inner tray 2 can be easily and stably wiped off, and the ease of use can be improved.

On the other hand, when replacing the inner plate 2 after using up the contents W, for example, as shown in FIG. Push it upwards with . Thereby, the push-up piece 52 can be pushed upward while rotating the entire operation piece 50 around the rotation shaft 51. Therefore, an upward external force can be applied to the bottom wall portion 2a of the inner plate 2 via the push-up piece 52.

Further, since the operation piece 50 itself rotates, as the push-up piece 52 rotates upward, the rotation shaft 51 moves toward the left so that the engagement piece 53 separates from the side wall 2b of the inner tray 2. rotate around. Thereby, the engagement protrusion 54 can be separated from the engagement recess 30, and the engagement between the engagement protrusion 54 and the engagement recess 30 can be released. Therefore, relative movement of the inner plate 2 with respect to the inner container 10 can be allowed.

Therefore, using the push-up piece 52, the inner plate 2 can be pushed upward with respect to the inner container 10, and the inner plate 2 can be easily removed from the inner container 10. As a result, the used inner plate 2 can be replaced, and, for example, a new inner plate 2 filled with the contents W can be set.
In particular, by rotating the operating piece 50 around the rotating shaft 51, the pushing up operation of the inner plate 2 using the push-up piece 52 and the disengaging operation of the inner plate 2 using the engaging piece 53 can be performed in a series. Since this can be done simultaneously in the same flow, the operability of removing the inner plate 2 can be improved.

As explained above, according to the compact container 1 of this embodiment, the inner plate 2 can be made difficult to come off from the inner container 10 during use. On the other hand, at the time of replacement, the inner plate 2 can be reliably removed from the inner container 10 with one touch, for example, and the operability for removing the inner plate 2 can be improved. Therefore, replacement of the inner plate 2, etc. can be performed easily and smoothly.

Furthermore, in the compact container 1 of this embodiment, as shown in FIG. When the entire operation piece 50 is rotated around the rotation axis 51 by the push-up operation, the push-up piece 52 and the engagement piece 53 can be displaced so as to rotate around the connection line N. can. Therefore, it is possible to suppress each of the push-up piece 52 and the engagement piece 53 from rotating excessively. Therefore, there is no need to secure a large rotation space, which contributes to making the compact container 1 smaller and thinner.

Further, the outer shape of the operation piece 50 is formed by a first slit hole 60 formed in the inner circumferential wall 12 and a second slit hole 70 formed in the inner bottom wall 11. Therefore, the operation piece 50 can be formed by partially partitioning a part of the inner circumferential wall 12 and the inner bottom wall 11 by the first slit hole 60 and the second slit hole 70. Therefore, the operation piece 50 can be integrally formed to fit within the basic shape of the inner container 10, and the presence of the operation piece 50 causes problems such as an increase in the external size or thickness of the inner container 10. Never. Therefore, in this respect as well, it is possible to contribute to making the compact container 1 itself smaller and thinner.

Further, when the push-up piece 52 is pushed up, the entire operation piece 50 can be rotated around the rotation axis 51 while the rotation axis 51 itself having an L-shaped cross section is torsionally deformed. At this time, as shown in FIG. 6, since the upward protrusion amount P1 of the first rotating piece 51a is at least the thickness T2 of the second rotating piece 51b, the strength of the rotating shaft 51 against stress in the vertical direction is can be improved. Therefore, the rotating shaft 51 itself can be stably torsionally deformed, and the inner plate 2 can be appropriately pushed up.
Moreover, since the upward protrusion amount P1 of the first rotating piece 51a is set to be 1.5 times or less than the thickness T2 of the second rotating piece 51b, the rotating shaft 51 itself is less likely to be torsionally deformed. This can be prevented.

Similarly, since the protrusion amount P2 of the second rotating piece 51b toward the inner container 10 is at least the thickness T1 of the first rotating piece 51a, the strength of the rotating shaft 51 against horizontal stress is improved. Can be done. Therefore, when the operation piece 50 is pushed up, the rotation shaft 51 itself can be prevented from being deformed to swing along the plane of the internal bottom wall 11 of the inner container 10, and the inner container 10 can be 2 can be pushed up appropriately.
Moreover, since the protrusion amount P2 of the second rotating piece 51b toward the inner container 10 is set to be 1.5 times or less than the thickness T1 of the first rotating piece 51a, the rotating shaft 51 itself is torsionally deformed. It is possible to prevent this from becoming difficult.

Further, in the above embodiment, the length of the third linear slit 63 in the first slit hole 60 and the third linear slit 73 in the second slit hole 70 along the front-rear direction L1 is within the range of 6 mm to 15 mm. is preferred.
By setting the lengths of the third linear slits 63 and 73 within the above range, the push-up operation (rotation operation) of the operation piece 50 can be performed more reliably while appropriately twisting and deforming the rotation shaft 51. can.
If the length of the third linear slits 63 and 73 is longer than 15 mm, the rigidity of the rotation shaft 51 will be insufficient against the pushing force through the push-up piece 52, and for example, the rotation shaft 51 This may lead to inconveniences such as bending and deformation. On the other hand, if the length of the third linear slits 63 and 73 is shorter than 6 mm, the rigidity of the rotation shaft 51 becomes too high, making it difficult to push up the operation piece 50 (rotation operation). There is a risk that it will become.

Further, in the above embodiment, it is preferable that the pair of third linear slits 63 and the pair of third linear slits 73 are formed with an interval within a range of 8 mm to 20 mm.
In particular, when the distance between the pair of third linear slits 63 is closer than 8 mm, the width of the base end of the push-up piece 52b becomes narrow in the front-rear direction L1, so when the push-up piece 52 is pushed up. When this happens, the base end side may be deformed so as to bend upward, and the rotation shaft 51 may not be rotated and deformed appropriately. On the other hand, if the distance between the pair of third linear slits 63 is greater than 20 mm, the pushing up force applied to the pushing up piece 52 will be difficult to be transmitted to the rotation shaft 51, and the pushing up force of the operating piece 50 will be difficult to transmit. There is a possibility that the lifting operation (rotating operation) may become difficult.

The embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by those skilled in the art, those that are substantially the same, and those that are equivalent.

In the embodiment described above, the lid 5 is connected to the container body 3 via the hinge part 4 so as to be openable and closable, but the present invention is not limited to this case. For example, the lid 5 may be slidably attached to the container body 3, or the lid 5 may be combined so that it can be removed from the container body 3.

Further, in the above embodiment, the operation piece 50 is placed on the left side of the inner container 10, but the position of the operation piece 50 is not limited to this case, and for example, it may be placed on the right side or the front side of the inner container 10. You may change it as appropriate.
Further, although the engagement recess 30 is formed on the side wall 2b side of the inner plate 2 and the engagement protrusion 54 is formed on the engagement piece 53 side of the operation piece 50, if they can be engaged with each other, for example, the inner plate An engagement convex portion functioning as an engaged portion may be formed on the side wall portion 2b of the operation piece 50, and an engagement recess functioning as an engagement portion may be formed on the engagement piece 53 side of the operation piece 50.

Further, in the above embodiment, the operation piece 50 is formed so that the rotation shaft 51 is arranged along the continuous line N between the inner circumferential wall 12 and the inner bottom wall 11 of the inner plate 2, but this is not limited to this case. It's not something you can do. For example, the rotation shaft 51 may be arranged within the plane of the internal bottom wall 11 or within the plane of the internal circumferential wall 12.
However, by arranging the rotation shaft 51 along the continuous line N between the inner circumferential wall 12 and the inner bottom wall 11 of the inner plate 2, the push-up piece 52 and the engagement piece 53 can be moved as described above. This is preferable because it is possible to prevent each of them from rotating excessively.

Further, in the above embodiment, the case where the shape of the container main body 3 is square in plan view has been described as an example, but the shape is not limited to this case, and as described above, for example, it can be shaped like a circle, an ellipse, etc. , polygonal shape, etc. may be changed as appropriate.

For example, as shown in FIG. 8, a compact container 80 may be used in which the container body 3 is formed to have a circular shape in plan view. In addition, in FIG. 8, illustration of the inner plate 2 and the lid body 5 is omitted.
In this case, since the accommodating portion 19 of the inner container 10 can be formed into a circular shape in plan view, it is possible to accommodate the circular inner plate 2 together with, for example, a general circular cosmetic puff. In the illustrated example, the operation piece 50 is formed such that the rotation shaft 51 extends along the left-right direction L2.
Even with the compact container 80 configured in this way, the same effects as those of the above embodiment can be achieved.
