A bending auxiliary portion 20a that facilitates bending is provided. The bending auxiliary portion 20a is a concave groove formed on the back surface side (−Z side) of the top wall portion 80 (that is, the flat plate portion 21, the curved portion 22, the inner wall portion 24, and the peripheral portion 23). As shown in FIG. 6, the cross section of the bending assisting portion 20a is substantially semicircular. The cross-sectional shape of the bending assisting portion 20a is not limited to the semicircular shape, but may be other shapes such as a rectangular shape or a triangular shape. However, in order to relieve stress concentration when the lid portion 20 is bent, A curve is preferred.

  The first fitting portions 60 </ b> A and 60 </ b> B detachably fit the lid portion 20 and the frame portion 40 at a position on the rotation tip side of the lid portion 20. The first fitting portions 60A and 60B are arranged at an approximately equal distance across the center of the container 1 in the X direction. In addition, since the structure of 1st fitting part 60A, 60B is the same, about the component of 1st fitting part 60B, it is "B" with respect to the code | symbol of the component of 1st fitting part 60A in the figure. Only the first fitting portion 60A will be described below.

  FIG. 6 is a cross-sectional view taken along line BB in FIG. The first fitting portion 60A includes a first engagement protrusion 46A and a first engagement recess 62A. The first engaging protrusion 46A is provided so as to protrude outward (−Y side) from the long side portion 48B of the outer wall portion 42 of the frame portion 40. 46 A of 1st engaging protrusions are formed in the shape which curves in the direction which goes to the -Z side gradually as it goes to the -Y side.

  The first engaging recess 62A is provided to extend from the long side portion 28B of the outer wall portion 25 of the lid portion 20 to the −Z side. The first engagement recess 62A is disposed at the same position as the first engagement protrusion 46A in the X direction. The first engagement recess 62A includes a hole 31A that fits the first engagement protrusion 46A at a position facing the first engagement protrusion 46A when the lid portion 20 closes the opening 56, and a hole It has the 1st holding part 32A extended and arranged to the -Z side of part 31A. When the first engagement protrusion 46A is fitted into the hole 31A, the + Z side end surface of the first gripping portion 32A in the first engagement recess 62A is the same as the −Z side end surface of the first engagement protrusion 46A. An engaging surface 36A to be engaged is formed, and the rotation of the lid 20 in the direction in which the opening 56 is opened is restricted.

  A rib 14 is provided on the surface on the −Z side of the peripheral portion 23 in the first fitting portions 60A and 60B. The ribs 14 are provided in a grid pattern extending in the Y direction so as to connect the inner wall portion 24 and the outer wall portion 25 and extending in the X direction at intervals. By providing the rib 14, the lid portion 20 is prevented from being deformed in the region where the first fitting portions 60 </ b> A and 60 </ b> B are disposed.

The second fitting portions 70A and 70B detachably fit the lid portion 20 and the frame portion 40 at positions closer to the hinge portion 30 (+ Y side) than the notch portion 85.
The second fitting portion 70A and the second fitting portion 70B are arranged at the same position in the Y-axis direction, and the second fitting portion 70A is arranged in the short side portions 29A and 49A in the X-axis direction. The second fitting portion 70B is disposed on the short side portions 29B and 49B. In addition, since the structure of 2nd fitting part 70A, 70B is the same, only 2nd fitting part 70A is demonstrated below.

  FIG. 7 is a cross-sectional view taken along the line CC in FIG. 1, and is a detailed view of a main part of the second fitting portion 70A. The second fitting portion 70A includes a second engagement protrusion 26A and a second engagement recess 21A. The second engagement protrusion 26A is provided to protrude outward (+ X side) from the short side portion 29A of the outer wall portion 42 of the frame portion 40. 26 A of 2nd engagement protrusions are formed in the shape which curves in the direction which goes to-Z side gradually as it goes to + X side.

  The second engagement recess 21 </ b> A is provided in the short side portion 29 </ b> A of the outer wall portion 25 in the lid portion 20. The second engagement recess 21A has a hole 33A that fits the second engagement protrusion 26A at a position facing the second engagement protrusion 26A when the lid 20 closes the opening 56. ing. On the outer wall 25 located on the −Z side with respect to the hole 33A, a second grip 34A is provided so as to protrude toward the −Z side. When the second engagement protrusion 26A is fitted into the hole 33A, the end surface on the + Z side of the second gripping portion 34A in the second engagement recess 21A is the end surface on the −Z side of the second engagement protrusion 26A. An engaging surface 35A to be engaged is formed, and the rotation of the lid 20 in the direction in which the opening 56 is opened is restricted. The position of the engagement surface 35A in the Z direction is preferably on the + Z side relative to the position of the engagement surface 36A in the first fitting portion 60A in the Z direction.

Next, the operation of the container 1 having the above configuration will be described.
In order to close the opening 56 in the container 1, for example, the lid 20 in the opened state shown in FIG. 4 is operated and rotated counterclockwise around the hinge 30 as a fulcrum. Due to the rotation of the lid part 20, the second fitting part is close to the hinge part 30 that is the pivot center and the distance in the rotational direction between the lid part 20 and the frame part 40 is shorter than the first fitting parts 60 </ b> A, 60 </ b> B. 70A and 70B start fitting first.

  That is, in the outer wall portions 25 of the second fitting portions 70A and 70B, as the second gripping portions 34A and 34B located on the −Z side with respect to the hole portions 33A and 33B, the rotation of the lid portion 20 proceeds. The second engaging protrusions 26A and 26B come into contact with each other, and are elastically deformed outward and bent along the curved shape of the second engaging protrusions 26A and 26B. When the lid 20 further rotates and reaches the position where the second engaging projections 26A, 26B and the holes 33A, 33B face each other, the second gripping portions 34A, 34B move inward by the elastic restoring force. The second engaging protrusions 26A and 26B are fitted in the holes 33A and 33B, respectively. Thereby, in 2nd fitting part 70A, 70B, rotation of the cover part 20 to the direction in which the opening part 56 is open | released is controlled.

  In the second fitting portions 70A and 70B, after the second gripping portions 34A and 34B come into contact with the second engaging protrusions 26A and 26B, respectively, the hole portions 31A are formed in the first fitting portions 60A and 60B. , 31B, the first gripping portions 32A, 32B are in contact with the first engaging protrusions 46A, 46B, respectively, as the rotation of the lid portion 20 proceeds, and the first engaging protrusions 46A. , And elastically deforms outward along the curved shape of 46B. When the lid 20 further rotates and reaches the position where the first engaging protrusions 46A, 46B and the holes 31A, 31B face each other, the first holding portions 32A, 32B move inward by the elastic restoring force. The first engaging protrusions 46A and 46B are fitted in the holes 31A and 31B, respectively. Thereby, in 1st fitting part 60A, 60B, rotation of the cover part 20 to the direction in which the opening part 56 is open | released is controlled.

  Ribs 15 are provided on the surface on the −Z side of the peripheral portion 23 in the second fitting portions 70A and 70B. The rib 15 extends in the X direction and connects the inner wall portion 24 and the outer wall portion 25, and the rib 15 extends in the Y direction, and is provided in a lattice shape with a space therebetween. By providing the rib 15, the lid 20 is prevented from being deformed in the region where the second fitting portions 70 </ b> A and 70 </ b> B are disposed.

  Here, when the lid portion 20 is rotated by operating near the first fitting portions 60A and 60B, the second fitting portions 70A and 70B have the length of the lid portion 20 in the Y-axis direction being ½. If it is arrange | positioned rather than the hinge part 30 side rather than the position which becomes, 2nd fitting part 70A, 70B will be in the position away from both the rotation operation part and the hinge part 30. For this reason, the lid 20 on the side opposite to the rotation direction at the positions of the second fitting portions 70A and 70B is a resistance due to the contact between the second gripping portions 34A and 34B and the second engaging protrusions 26A and 26B. The deflection of the becomes larger. As a result, even if the first engagement protrusions 46A, 46B and the holes 31A, 31B are completely fitted in the first fitting parts 60A, 60B, the second engagement protrusions 70A, 70B are not in the second engagement protrusions. There is a possibility that the fitting between the portions 26A and 26B and the holes 33A and 33B is not completed, and the opening portion 56 is not sufficiently closed (sealed) by the lid portion 20.

  On the other hand, in the present embodiment, the second fitting portions 70A and 70B are disposed on the hinge portion 30 side with respect to the position where the length of the lid portion 20 in the Y-axis direction is ½, Since the distance is short, the rotation direction at the position of the second fitting portions 70A and 70B generated when the second gripping portions 34A and 34B come into contact with the second engaging protrusions 26A and 26B is opposite to the rotation direction. The bending of the lid portion 20 is reduced. Therefore, when the fitting between the first engagement protrusions 46A and 46B and the holes 31A and 31B is completed in the first fitting portions 60A and 60B, the second engagement also in the second fitting portions 70A and 70B. The fitting of the protrusions 26A, 26B and the holes 33A, 33B is completed, and the closing of the opening 56 by the lid 20 is completed.

  In the container 1, in order to open the opening 56, the first gripping portions 32A and 32B in the first fitting portions 60A and 60B are gripped and bent outward, and the first engaging protrusions 46A and 46B and the holes are opened. While releasing the fitting with the parts 31A and 31B, the lid part 20 is rotated in the clockwise direction in FIG.

  Here, the outer wall 25 is provided with a notch 85, and the ceiling wall 80 is provided with a bending assisting part 20a. Therefore, the lid 20 has a bending strength at the position where the notch 85 is provided. It is smaller than other positions. Therefore, when the lid 20 is rotated while holding the first gripping portions 32A and 32B, the lid 20 has a rotation tip side (−Y side) with respect to the hinge portion 30 side as shown in FIG. The bend assisting portion 20a is bent at the position where the notch portion 85 is provided. Therefore, it is difficult for the force applied to grip the first gripping portions 32A and 32B and rotate the lid portion 20 to be transmitted to the second fitting portions 70A and 70B. Therefore, in order to rotate the lid 20 and open the opening 56, after releasing the fitting in the first fitting parts 60A and 60B, the second gripping part in the second fitting parts 70A and 70B again. 34A and 34B are gripped and bent outward, and the fitting between the second engaging protrusions 26A and 26B and the holes 33A and 33B is released. Thereby, since the fitting in the first fitting portions 60A and 60B and the second engaging protrusions 26A and 26B is released, the lid portion 20 can be rotated to open the opening 56.

  As described above, the container 1 of the present embodiment cannot perform the fitting release with respect to the first fitting portions 60A and 60B and the second fitting portions 70A and 70B in a consistent and continuous operation, Since it takes time and effort to open the opening 56, it cannot be easily opened by a child and functions as a child proof. Moreover, since the notch 85 is provided in the 1st fitting part 60A, 60B side, the container 1 of this embodiment has a container main body with fingers even if the cover part 20 opens through the notch 85. It is possible to make it difficult to take out the contents accommodated in 50.

  Moreover, in the container 1 of this embodiment, since the notch part 85 is provided in the hinge part 30 side rather than the position where the length of the Y-axis direction of the cover part 20 becomes 1/2, the first fitting part 60A. The distance between the first gripping portions 32A and 32B and the cutout portion 85 at 60B becomes longer, and the top wall portion 80 of the lid portion 20 can be easily bent when the opening portion 56 is opened. Therefore, the container 1 of this embodiment cannot be easily opened by a child. In the container 1 of the present embodiment, the second fitting portions 70A and 70B are also positioned on the hinge portion 30 side from the position where the length of the lid portion 20 in the Y-axis direction is ½, and the opening It is possible to cope with a child proof that cannot be easily opened while reliably opening and closing the portion 56 to ensure the sealing performance of the container 1.

  Moreover, in the container 1 of this embodiment, since 2nd fitting part 70A, 70B is arrange | positioned on the + Z side rather than 1st fitting part 60A, 60B, it precedes 1st fitting part 60A, 60B. The fitting operation in the second fitting portions 70 </ b> A and 70 </ b> B can be started, and the opening 56 can be closed more reliably by the lid portion 20.

  As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the examples. Various shapes, combinations, and the like of the constituent members shown in the above-described examples are examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, in the above-described embodiment, one cutout portion 85 is provided on each of the outer wall portions 25 of the short side portions 29A and 29B. However, one or more cutout portions 85 may be provided on each side portion. Moreover, it is good also as a structure which takes time for opening by providing the outer side wall part 25 in long side part 28A, 28B by providing in long side part 28A, 28B instead of short side part 29A, 29B.
