Summary of the Invention

Problems to be Solved by the Invention

[0005] In the double container disclosed in FIG. 9 of Patent Document 1, by bending the tongue piece inward, the engagement between the tongue piece and the notch is released, and the refill container can be taken out from the wide-mouth container. Therefore, when the depth of the notch is shallow and the length of the tongue piece is short, a large force is required to bend the tongue piece inward. On the other hand, when the depth of the notch is increased and the length of the tongue piece is increased in order to bend the tongue piece inward with a small force, there is a problem that the appearance deteriorates. In particular, the so-called premium feeling, that is, the high-class feeling, is impaired.

[0006] Also, when taking out the refill container by bending the refill container itself inward as shown in FIG. 7 of Patent Document 1, it is necessary to provide a gap for the refill container to bend between the refill container and the wide-mouth container as shown in FIG. 6 of Patent Document 1. As a result, there is a problem that the storage capacity of the contents stored in the refill container is reduced accordingly.

[0007] The present invention has been made in view of the problems of the conventional technology as described above, and in a container in which an inner container is housed in an outer container, it is possible to take out the inner container from the outer container without reducing the storage capacity of the inner container and without significantly damaging the appearance and without requiring a large force. The purpose is to provide a container.

Means for Solving the Problems

[0008] In order to achieve the above object, the present invention has an inner container that has a first opening and in which contents are stored through the first opening, has an outer container that has a second opening and in which the inner container is stored through the second opening, and a lid body that closes the second opening, and is a container having wherein the outer container has a cylindrical upper container portion on its outer surface that has a screw structure that engages with the lid body in a screw manner, and a lower container portion that is continuous with the outer container portion on the side opposite to the second opening of the upper container portion, the upper container portion has a notch portion that is cut out by a first length from the second opening in a part of the circumferential direction, wherein the inner container has a main body portion in which the contents are stored, and a tongue piece that is connected to an end portion of the main body portion on the first opening side and extends by a second length that is equal to or less than the first length along the outer surface of the main body portion at a predetermined interval from the end portion, the notch portion has a first engaging portion on the outer peripheral side in the thickness direction of the upper container portion, When the inner container is housed in the outer container, the tongue piece enters the notch, and the second engaging portion provided on the side of the tongue piece engages with the first engaging portion. When the tongue piece bends toward the main body portion side, the engagement between the first engaging portion and the second engaging portion is released. The container is such that this occurs.

[0009] In the present invention configured as described above, when the inner container is housed in the outer container, the tongue piece of the inner container enters the notch provided in the upper container portion having a screw structure that is screwed to the lid in the outer container, and the second engaging portion provided on the side of the tongue piece engages with the first engaging portion provided in the notch. Here, since the tongue piece extends along the outer surface of the main body portion at a certain interval from the end connected to the main body portion, it can be bent toward the main body portion side. On the other hand, since the first engaging portion is provided on the outer peripheral side in the thickness direction of the notch, when the tongue piece is bent toward the main body portion side, the engagement between the first engaging portion and the second engaging portion is released.

[0010] In this way, in the region hidden by the lid when the outer container is screwed to the lid and the lid is attached, the tongue piece and the notch for bending when taking out the inner container from the outer container are arranged. Therefore, the sizes of the tongue piece and the notch can be increased without significantly damaging the appearance. By being able to increase the size of the tongue piece, the inner container can be taken out from the outer container without requiring a large force. Also, since the tongue piece extends along the outer surface of the main body portion at a predetermined interval from the end connected to the main body portion and the first engaging portion is provided on the outer peripheral side in the thickness direction of the notch, there is no need to provide a gap for bending the tongue piece between the inner container and the outer container. As a result, a reduction in the storage capacity of the inner container is avoided.

[0011] Also, the second engaging portion may be provided on the side near the tip of the tongue piece.

[0012] In such a configuration, when pushing the vicinity of the tip of the tongue piece toward the main body part in order to bend the tongue piece toward the main body part side, a second engaging part exists in the vicinity of the region where the force is applied, and the loss of the force applied to the tongue piece can be suppressed as much as possible.

[0013] Further, the first and second engaging parts may be configured as unevenness that alternates with each other.

[0014] In such a configuration, the first engaging part and the second engaging part can be engaged with a simple configuration.

[0015] Further, the notch part may have an engagement preparation part that deforms the tongue piece when the second engaging part engages with the first engaging part, and the second engaging part may be configured to engage with the first engaging part in a state where the deformation is released after the tongue piece is deformed.

[0016] In such a configuration, when the first engaging part and the second engaging part are engaged, the tongue piece deforms, and then the deformation is released, thereby generating sound and vibration. As a result, it is easy to recognize that the first engaging part and the second engaging part are engaged.

[0017] Further, the first length of the notch part may be the same as the length in the continuous direction between the lower container part and the upper container part.

[0018] In such a configuration, the length of the tongue piece that enters the notch part can be set to the maximum length hidden by the lid body, and the inner container can be taken out of the outer container with a smaller force.

[0019] Further, the inner container may be configured to have a flange part that is in surface contact with the end surface on the second opening side of the upper container part at the end on the first opening side.

[0020] In such a configuration, when the inner container is housed in the outer container, the flange part rides on the upper end surface of the outer container, and the inner container can be stably fixed.

Effects of the Invention

[0021] According to the present invention, in a container in which an inner container is housed in an outer container, the inner container can be taken out of the outer container without reducing the storage capacity of the inner container and without significantly impairing the appearance and without requiring a large force.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0024] 〈Overall Configuration〉 FIG. 1 is a diagram showing an embodiment of the container of the present invention, and is a perspective view of the container 1 seen from obliquely above. FIG. 2 is an external perspective view showing a state where the lid 10 is removed from the container 1 shown in FIG. 1.

[0025] As shown in FIGS. 1 and 2, the present embodiment is a container 1 having a lid 10, an outer container 20, and an inner container 30, wherein the inner container 30 is accommodated in the outer container 20, and the opening portion of the container 1 is covered by the lid 10.

[0026] 〈Lid 10〉 FIG. 3 is a diagram showing the configuration of the lid 10 shown in FIG. 1, and is an external perspective view seen from obliquely below.

[0027] As shown in FIG. 3, the lid 10 shown in FIG. 1 has a top surface 11, an outer side wall 12, and an inner side wall 13.

[0028] The top surface 11 is configured in a circular plate shape. The outer side wall 12 is configured in a cylindrical shape that stands up from the outer periphery of the top surface 11 on one surface of the top surface 11. The inner side wall 13 is configured in a cylindrical shape that stands up on one surface of the top surface 11 inside the outer side wall 12 while maintaining a certain interval from the outer side wall 12. A screw structure 14 that can be screw-engaged is provided on the inner surface of the inner side wall 13.

[0029] The lid body 10 configured as described above can be integrally formed from resin or the like by integrating the top surface 11, the outer side wall 12, and the inner side wall 13.

[0030] 〈Outer container 20〉 FIG. 4 is a diagram showing the configuration of the outer container 20 shown in FIG. 1, and is a perspective view seen from obliquely above.

[0031] As shown in FIG. 4, the outer container 20 shown in FIG. 1 is configured such that the upper container portion 21 and the lower container portion 22 are continuously formed.

[0032] The upper container portion 21 is configured in a cylindrical shape, and one end of the cylindrical shape serves as an opening 23 for accommodating the inner container 30 in the outer container 20 or taking out the inner container 30 from the outer container 20. Note that the opening 23 is an example of the second opening in the present invention. The diameter R1 of the cylindrical shape of the upper container portion 21 is substantially the same as the inner diameter of the inner side wall 13 of the lid body 10. A screw structure 25 with which the screw structure 14 of the lid body 10 can be engaged is provided on the outer peripheral surface of the upper container portion 21. Further, two notch portions 27 are provided in the upper container portion 21. The two notch portions 27 are notched by a first length from the end on the opening 23 side of the upper container portion 21 toward the end on the side continuous with the lower container portion 22 in a region facing each other through the center of the cylindrical shape of the upper container portion 21. The detailed configuration of the notch portion 27 will be described later.

[0033] The lower container part 22 is formed in a cylindrical shape, and the end opposite to the end continuous with the cylindrical upper container part 21 is closed to form a bottom part 29. Thus, the bottom part 29 is formed in a circular plate shape. The cylindrical diameter R2 of the lower container part 22, which is the outer diameter of the lower container part 22 in the direction orthogonal to the continuous direction of the upper container part 21 and the lower container part 22, is longer than the cylindrical diameter R1, which is the outer diameter of the upper container part 21 in the same direction. Therefore, the lower container part 22 has a shoulder part 24 at the continuous part with the upper container part 21 for connecting the lower container part 22 to the upper container part 21. The shoulder part 24 is formed in a donut plate shape, thereby connecting the upper container part 21 and the lower container part 22 with different outer shapes. If the diameter of the bottom part 29 of the lower container part 22 is made the same as the diameter of the top surface 11 of the lid body 10, when the lid body 10 is attached to the outer container 20, as shown in FIG. 1, the outer peripheral surface of the lid body 10 can be positioned on the extension of the outer peripheral surface of the outer container 20.

[0034] The outer container 20 configured as described above can be formed by integrating the upper container part 21 and the lower container part 22 and made of glass, resin, or the like.

[0035] FIGS. 5A and 5B are diagrams showing the detailed configuration of the notch part 27 shown in FIG. 4. FIG. 5A is a view seen from the direction facing the outer peripheral surface of the upper container part 21, and FIG. 5B is a view seen from the direction facing the side surface of the notch part 27.

[0036] As shown in FIG. 5A, the notch part 27 shown in FIG. 4 has unevenness on both of its side surfaces, and thus has a convex part 28b and a concave part 28a, respectively. The convex part 28b is an example of an engagement preparation part in the present invention. The convex part 28b is formed by the side surface of the notch part 27 protruding. The concave part 28a is an example of a first engagement part in the present invention, and has a shape recessed with respect to the convex part 28b by being adjacent to the lower part of the convex part 28b. As shown in FIG. 5B, these convex part 28b and concave part 28a are provided on the outer peripheral side (arrow B side in the figure) in the thickness direction of the notch part 27.

[0037] <Inner container 30> FIG. 6A and FIG. 6B are diagrams showing the configuration of the inner container 30 shown in FIG. 2. FIG. 6A is a perspective view of the inner container 30 as seen obliquely from above, and FIG. 6B is a side view of the inner container 30 as seen from the side. FIG. 7 is a diagram showing the detailed configuration of the tongue piece 32 shown in FIGS. 6A and 6B.

[0038] As shown in FIGS. 6A and 6B, the inner container 30 shown in FIG. 2 has a main body portion 31 and two tongue pieces 32.

[0039] The main body portion 31 is configured in a pot shape having an opening 33 and is sized to be able to enter through the opening 23 of the outer container 20. Therefore, the diameter of the opening 33 of the main body portion 31 is shorter than the diameter of the opening 23 of the outer container 20, and the height of the main body portion 31 is lower than the length from the end face 26 on the opening 23 side of the outer container 20 to the bottom 29. Note that the opening 33 is an example of the first opening in the present invention. A flange portion 34 protruding outward is continuous with the end portion on the opening 33 side of the main body portion 31. The flange portion 34 has a donut plate shape by protruding a certain width outward from the end portion on the opening 33 side of the main body portion 31.

[0040] The tongue piece 32 is connected to the end of the main body 31 on the opening 33 side via the flange portion 34. The two tongue pieces 32 are respectively continuous with regions of the flange portion 34 that face each other through the center of the opening 33. One end of the tongue piece 32 is continuous with the flange portion 34 and extends therefrom along the outer surface of the main body 31 at a predetermined interval d1. As a result, a gap 36 is formed between the outer peripheral surface of the main body 31 and the tongue piece 32. The second length of the tongue piece 32 is the same as the length in the continuous direction between the upper container portion 21 and the lower container portion 22 of the notch portion 27 of the outer container 20. As shown in FIG. 7, a protrusion 35 protruding from the side is provided on the side of the tongue piece 32. The protrusion 35 is an example of the second engaging portion in the present invention. As shown in FIG. 2, when the inner container 30 is housed in the outer container 20 and the tongue piece 32 enters the notch portion 27 of the outer container 20, the protrusion 35 is provided at a position facing the recess 28a of the notch portion 27. Further, the protrusion 35 has a shape that can enter the recess 28a. Therefore, the length of the protrusion 35 in the extending direction of the tongue piece 32 is shorter than the length in the adjacent direction to the convex portion 28b of the recess 28a. That is, the recess 28a and the protrusion 35 have alternating concavities and convexities. The width of the tongue piece 32 including the protrusion 35 is wider than the width of the region where the convex portion 28b of the notch portion 27 is provided and narrower than the width where the recess 28a is provided. Also, the width of the region of the tongue piece 32 where the protrusion 35 is not provided is narrower than the width of the region where the convex portion 28b of the notch portion 27 is provided.

[0041] The inner container 30 configured as described above can be integrally formed from resin or the like by integrating the main body 31 and the tongue piece 32 via the flange portion 34. By configuring the inner container 30 from a material that is easy to process, such as resin, the tongue piece 32 and the protrusion 35 can be easily provided.

[0042] 〈Relationship between the outer container 20 and the inner container 30〉 Hereinafter, a form in which the inner container 30 is housed in the outer container 20 configured as described above will be described.

[0043] Figs. 8 and 9 are views showing a form in which the inner container 30 is housed in the outer container 20. Fig. 8 is a view seen from the direction facing the notch portion 27, and Fig. 9 shows the A-A cross section shown in Fig. 2.

[0044] In the container 1 shown in Fig. 1, the inner container 30 is housed in the outer container 20.

[0045] As described above, the diameter of the opening 33 of the main body portion 31 is shorter than the diameter of the opening 23 of the outer container 20. Therefore, as shown in Figs. 8 and 9, the main body portion 31 of the inner container 30 can enter from the opening 23 of the outer container 20, and the inner container 30 is housed in the outer container 20.

[0046] On one hand, the tongue piece 32 of the inner container 30 is continuous with the main body portion 31 via the flange portion 34 and extends along the outer surface of the main body portion 31 at a predetermined interval, so it does not enter from the opening 23 of the outer container 20. However, the second length of the tongue piece 32 is the same as the length in the continuous direction of the upper container portion 21 and the lower container portion 22 of the notch portion 27 of the outer container 20. Also, the width including the protrusion 35 of the tongue piece 32 is wider than the width of the region where the convex portion 28b of the notch portion 27 is provided and narrower than the width where the concave portion 28a is provided, and the width of the region where the protrusion 35 of the tongue piece 32 is not provided is narrower than the width of the region where the convex portion 28b of the notch portion 27 is provided. Therefore, the tongue piece 32 of the inner container 30 enters the notch portion 27 of the outer container 20. And on the side of the tongue piece 32, a protrusion 35 protruding from the side is provided, while in the notch portion 27, a concave portion 28a is provided adjacent to the lower part of the convex portion 28b protruding from the side surface. Therefore, the protrusion 35 of the tongue piece 32 fits into and engages with the concave portion 28a of the notch portion 27, so that the inner container 30 is fixed in a state of being accommodated in the outer container 20. In this way, since the concave portion 28a and the protrusion 35 are alternating concavities and convexities, the concave portion 28a and the protrusion 35 can be engaged with a simple structure. Note that although the convex portion 28b and the concave portion 28a of the notch portion 27 are provided on the outer peripheral side in the thickness direction of the notch portion 27 as shown in FIG. 5B, since the tongue piece 32 extends along the outer surface of the main body portion 31 at a predetermined interval, when the tongue piece 32 of the inner container 30 enters the notch portion 27 of the outer container 20, the protrusion 35 of the tongue piece 32 fits into and engages with the concave portion 28a of the notch portion 27.

[0047] Also, as described above, since the height of the main body portion 31 is lower than the length from the end face 26 on the opening 23 side to the bottom 29 of the outer container 20, as shown in FIG. 9, the flange portion 34 of the inner container 30 makes surface contact and rests on the end face 26 on the opening 23 side of the outer container 20, and the inner container 30 can be stably fixed.

[0048] After that, by screwing the screw structure 14 of the lid 10 onto the screw structure 25 of the outer container 20, the lid 10 can be attached to the outer container 20 to close the opening 23 of the outer container 20 with the lid 10.

[0049] <Usage form of Container 1> In recent years, among the containers 1 shown in FIG. 1, those configured to be able to refill the contents, so-called refills, are known from the perspective of environmental issues and the like. Therefore, also in the container 1 shown in FIG. 1, an inner container 30 containing contents such as cosmetics is provided as a refill product, and it may be possible for general consumers to accommodate the inner container 30 containing contents such as cosmetics in the outer container 20 or take it out of the outer container 20.

[0050] Hereinafter, the method of accommodating the inner container 30 in the outer container 20 and the method of taking it out of the outer container 20 will be described.

[0051] <Method of accommodating the inner container 30 in the outer container 20> First, the method of accommodating the inner container 30 in the outer container 20 will be described.

[0052] The inner container 30 is accommodated in the outer container 20 through the opening 23 of the outer container 20. At this time, as described above, the diameter of the opening 33 of the main body portion 31 is shorter than the diameter of the opening 23 of the outer container 20. Therefore, the main body portion 31 of the inner container 30 can be inserted through the opening 23 of the outer container 20. Also, when inserting the main body portion 31 of the inner container 30 through the opening 23 of the outer container 20, the position is adjusted so that the tongue piece 32 of the inner container 30 enters the notch portion 27 of the outer container 20. Note that as a form of providing the inner container 30, it may be one in which a sheet-like lid is detachably attached to the flange portion 34 so as to close the opening 33 and the inner container 30 contains contents such as cosmetics. In that case, the consumer who purchases the inner container 30 may peel off the sheet-like lid and accommodate the inner container 30 in the outer container 20, or may peel off the sheet-like lid after accommodating the inner container 30 in the outer container 20.

[0053] When the main body 31 of the inner container 30 is inserted into the opening 23 of the outer container 20 with the tongue piece 32 of the inner container 30 aligned so as to enter the notch 27 of the outer container 20, the tongue piece 32 of the inner container 30 enters the notch 27 and moves downward.

[0054] FIG. 10A is a diagram showing the positional relationship between the protrusion 35 provided on the tongue piece 32 and the convex portion 28b provided on the notch 27. FIG. 10B is a diagram showing a state where the protrusion 35 has overcome the convex portion 28b. FIG. 10C is a diagram showing a state where the tongue piece 32 has entered the notch 27.

[0055] As described above, although the length of the tongue piece 32 is the same as the length in the continuous direction of the upper container portion 21 and the lower container portion 22 of the notch 27 of the outer container 20, a convex portion 28b is provided on the side surface of the notch 27, and the width including the protrusion 35 of the tongue piece 32 is wider than the width of the region where the convex portion 28b of the notch 27 is provided.

[0056] Therefore, when the tongue piece 32 of the inner container 30 enters the notch 27 and moves in the direction of arrow C in FIG. 10A, the protrusion 35 of the tongue piece 32 comes into contact with the convex portion 28b of the notch 27.

[0057] However, as shown in FIG. 10A, the region where the protrusion 35 contacts the convex portion 28b is an inclined surface 35a whose height decreases toward the tip of the tongue piece 32. Further, the convex portion 28b is an inclined surface 28c such that the width of the notch 27 widens in the direction in which the tongue piece 32 comes into contact.

[0058] Therefore, if the tongue piece 32 is made of a bendable material such as resin, the tongue piece 32 with the protrusion 35 in contact with the convex portion 28b bends so as to be convex in the outer peripheral direction of the inner container 30, and as shown in FIG. 10B, the inclined surface 35a of the protrusion 35 slides on the inclined surface 28c of the convex portion 28b and can move in the direction of arrow C in FIG. 10A.

[0059] Then, when the protrusion 35 of the tongue piece 32 gets over the convex portion 28b of the notch 27, a concave portion 28a is adjacent to the lower side of the convex portion 28b. Since the width including the protrusion 35 of the tongue piece 32 is narrower than the width provided with the concave portion 28a, as shown in FIG. 10C, the protrusion 35 of the tongue piece 32 fits into and engages with the concave portion 28a of the notch 27.

[0060] At this time, when the tongue piece 32 returns from the deflected state to the non-deflected state, sound and vibration are generated. Thereby, it is easier to recognize that the protrusion 35 of the tongue piece 32 fits into and engages with the concave portion 28a of the notch 27.

[0061] In this way, when the protrusion 35 of the tongue piece 32 engages with the concave portion 28a of the notch 27, the tongue piece 32 is deformed by the protrusion 35 of the tongue piece 32 abutting against the convex portion 28b of the notch 27. Then, after the protrusion 35 of the tongue piece 32 gets over the convex portion 28b, the protrusion 35 of the tongue piece 32 engages with the concave portion 28a of the notch 27 in a state where the deformation of the tongue piece 32 is released.

[0062] In this way, the inner container 30 is fixed in a state of being housed in the outer container 20.

[0063] 〈Method for taking out the inner container 30 from the outer container 20〉 Next, a method for taking out the inner container 30 from the outer container 20 will be described.

[0064] The container 1 shown in FIG. 1 can take out the inner container 30 from the outer container 20. For example, when the inner container 30 containing contents such as cosmetics is provided as a refill product, and when the contents such as cosmetics contained in the inner container 30 housed in the outer container 20 are used up, in order to house a new inner container 30 in the outer container 20, the inner container 30 housed in the outer container 20 can be taken out.

[0065] As described above, when the inner container 30 is housed in the outer container 20, the protrusion 35 of the tongue piece 32 is engaged with the recess 28a of the notch portion 27. Therefore, the inner container 30 cannot be taken out of the outer container 20 as it is.

[0066] FIGS. 11A and 11B are diagrams for explaining a method of taking out the inner container 30 from the outer container 20, and show the positional relationship in the thickness direction of the tongue piece 32. In order to clearly show the positional relationship between the protrusion 35 and the recess 28a, the protrusion 35 and the region including the convex portion 28b protruding from the side surface of the notch portion 27 are each shown by hatching.

[0067] As described above, the convex portion 28b and the concave portion 28a are provided on the outer peripheral side in the thickness direction of the side surface of the notch portion 27. On the other hand, the tongue piece 32 extends along the outer surface of the main body portion 31 with a predetermined interval therebetween. Therefore, when the tongue piece 32 of the inner container 30 enters the notch portion 27 of the outer container 20, as shown in FIG. 11A, the protrusion 35 of the tongue piece 32 fits into and engages with the recess 28a of the notch portion 27.

[0068] In such a state, the inner container 30 cannot be taken out of the outer container 20.

[0069] Here, as described above, one end of the tongue piece 32 is continuous with the flange portion 34 and extends therefrom along the outer surface of the main body portion 31 with a predetermined interval therebetween. As a result, as shown in FIG. 11A, a gap 36 is formed between the outer peripheral surface of the main body portion 31 and the tongue piece 32.

[0070] Therefore, if the tongue piece 32 is made of a bendable material such as resin, as shown in FIG. 11B, the tongue piece 32 can be pushed toward the main body portion 31 in the direction of arrow D in the figure and bent toward the main body portion 31 side.

[0071] Then, as shown in FIG. 11B, the protrusion 35 of the tongue piece 32 no longer faces the recess 28a, and the engagement between the protrusion 35 and the recess 28a is released. Therefore, in this state, by moving the inner container 30 upward, the inner container 30 can be taken out from the outer container 20. Note that, in order to release the engagement between the protrusion 35 of the tongue piece 32 and the recess 28a of the notch 27 by bending the tongue piece 32 toward the main body portion 31 side, it is preferable that the distance d2 between the outer surface of the main body portion 31 of the inner container 30 and the convex portion 28b of the notch 27 is equal to or greater than the thickness of the tongue piece 32 in the state where the inner container 30 is housed in the outer container 20.

[0072] As described above, in the present embodiment, at the portion where the outer container 20 and the lid body 10 are screwed together, the tongue piece 32 of the inner container 30 is inserted into the notch 27 of the outer container 20, and the protrusion 35 of the tongue piece 32 and the recess 28a of the notch 27 are engaged with each other, so that the inner container 30 is fixed in a state of being housed in the outer container 20. Then, by bending the tongue piece 32 toward the main body portion 31 side of the inner container 30, the engagement between the protrusion 35 and the recess 28a is released, and the inner container 30 can be taken out from the outer container 20. In this way, the tongue piece 32 that is bent when the inner container 30 is taken out from the outer container 20 and the notch 27 into which the tongue piece 32 is inserted are arranged in a region hidden by the lid body 10 when the lid body 10 is attached to the outer container 20. Thereby, the sizes of the tongue piece 32 and the notch 27 can be increased without significantly damaging the appearance of the container 1, and since the size of the tongue piece 32 can be increased, the inner container 30 can be taken out from the outer container 20 without requiring a large force. Further, the tongue piece 32 extends along the outer surface of the main body portion 31 at a predetermined interval from the end connected to the main body portion 31, and the recess 28a is provided on the outer peripheral side in the thickness direction of the notch 27, so that there is no need to provide a gap for bending the tongue piece 32 between the inner container 30 and the outer container 20, thereby avoiding a reduction in the storage capacity of the inner container 30.

[0073] In addition, when bending the tongue piece 32 toward the main body 31, since the vicinity of the tip of the tongue piece 32 is pushed into the main body 31 side, if the protrusion 35 is provided on the side of the vicinity of the tip of the tongue piece 32, when pushing the tongue piece 32 into the main body 31 side, the protrusion 35 will exist near the area where the force is applied, and the loss of the force applied to the tongue piece can be suppressed as much as possible.

[0074] Also, the length of the notch 27 in the continuous direction of the upper container part 21 and the lower container part 22 may be the same as the length of the upper container part 21 in the same direction. In that case, the length of the tongue piece 32 can also be the same as the length of the upper container part 21 in the same direction. Thereby, the length of the tongue piece 32 can be set to the maximum length hidden by the lid body 10, and the inner container 30 can be taken out from the outer container 20 with a smaller force.

[0075] <Morphology of the convex part of the notch 27> Hereinafter, the morphology of the convex part provided on the side surface of the notch 27 will be described.

[0076] Figs. 12A to 12D are external perspective views showing the morphology of the convex part provided in the notch 27 of the outer container 20.

[0077] As shown in Fig. 12A, the convex part 28b shown in the above-described embodiment has an inclined surface 28c on the upper surface such that the width of the notch 27 becomes wider upward, and the angle Θ1 formed by the bottom surface 28d and the side surface of the notch 27 is 90°.

[0078] On the other hand, as the convex part provided in the notch 27 of the outer container 20, as shown in Fig. 12B, a convex part 128b in which the angle Θ2 formed by the bottom surface 28d and the side surface of the notch 27 is an acute angle may be used.

[0079] Also, as the convex part provided in the notch 27 of the outer container 20, as shown in Fig. 12C, a convex part 228b in which the shape of the opposing surface 228e facing the tongue piece 32 of the inner container 30 is not a square or a rectangle but a trapezoid when the inner container 30 is housed in the outer container 20 may be used.

[0080] Further, as the convex portion provided in the notch portion 27 of the outer container 20, as shown in FIG. 12D, the convex portion 328b having a raised portion 328f that rises downward on the bottom surface 328d may be used.
