Description

The present invention relates to a container.
This application claims priority on November 25, 2013 based on Japanese Patent Application No. 2013-242924 for which it applied to Japan, and uses the content here.

  As a cap in a tube container used for accommodation of dentifrice etc., and a bottle container used for accommodation of cosmetics etc., a hinge type cap fixed to the upper end portion of the container body by driving type fitting is known. A container provided with such a hinge-type cap is excellent in usability because it is easy to open the closing portion with one hand.

  However, when the diameter of the container main body is large, the diameter of the hinge-type cap also increases accordingly, so that the ease of opening the closing portion decreases. Moreover, the said hinge type cap becomes difficult to push out a content as the residual amount of a content decreases. Further, since the hinge-type cap generally has a large volume, it tends to have an image that the contents remain inside the cap and cannot be used up.

Therefore, a container is proposed in which the hinge-type cap is screwed and fixed to the container body by screwing, and the contents are used up by removing the hinge-type cap from the container body when the remaining amount of contents is low (For example, Patent Documents 1 to 3).
However, in the container, when the contents are used up, it is necessary to rotate and remove the hinge-type cap, so that the cap removal work is complicated.
Moreover, it cannot be said that a user necessarily likes a hinge type cap, and there exists a user who likes opening methods other than a hinge type. However, since the removal of the cap is complicated, the container cannot be used in such a way that the user selects the opening method according to his / her preference each time it is used.

Also, when the remaining amount is used up, the outer wall of the hinged cap is pushed inward so that the outer wall rises up the shoulder of the container body so that the cap can be removed. A container made in this manner has also been proposed (Patent Document 4).
However, it is not envisaged that the user selects the opening method according to his / her preference every time the user uses the container. Moreover, since it is assumed that the cap is removed at the end of use, it is not assumed that the cap can be attached and detached. Moreover, in the said container, when trying to open the closing part of the upper part of a hinge type cap, the cap itself may come off unexpectedly by pressing the outer wall part of a cap accidentally.

Japanese Patent Laid-Open No. 10-258853 JP 2008-155961 A JP 2010-275001 A JP 2003-12005 A

[First embodiment]
Hereinafter, an example of the container of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the container 1 according to the present embodiment includes a container main body 2 that contains contents, and a cap 3 that is detachably attached to the upper end of the container main body 2.

As shown in FIGS. 1 and 3, the container body 2 includes a body portion 10 that contains the contents, a shoulder portion 12 that is formed at the upper end of the body portion 10 and is inclined so as to gradually narrow toward the upper side, A cylindrical neck portion 14 projecting from the upper end of the portion 12 and having an open upper end.

The form of the body part 10 is not particularly limited as long as it can accommodate contents such as dentifrice, kneaded wasabi, kneaded glass, contents such as cosmetic cream, etc., for example, tubes, bottles, pouches, A metal can, a bottle, etc. are mentioned.
The cross-sectional shape of the trunk | drum 10 is not specifically limited, For example, circular, a polygon, an ellipse, a star shape etc. can be selected arbitrarily. Here, the “cross section” means a cross section when cut in a direction perpendicular to the longitudinal direction of the body portion.

  As shown in FIG. 3, a first locking portion 16 is formed in the neck portion 14 in an annular shape in the circumferential direction of the neck portion 14 so as to protrude from the outer peripheral surface 14 a. The first locking portion 16 forms a locking structure with a second locking portion 24 of the cap 3 described later when the cap 3 is attached to the upper end portion of the container body 2. Thereby, the cap 3 can be stably fixed to the container main body 2. “Locking structure” means that the first locking portion 16 and the second locking portion 24 are locked to each other. A typical example of the locking structure is undercut fitting.

The vertical cross-sectional shape of the first locking portion 16 is a triangular shape in this example, but is not limited to a triangular shape, and may be a semicircular shape, a rectangular shape, or the like.
Further, in the container of the present invention, a groove is formed in the circumferential direction on the outer peripheral side of the neck portion 14 instead of the protruding first locking portion 16, and the second locking portion 24 of the cap 3 is formed in the groove. The locking structure may be formed by being caught.
The neck part of the container main body in the container of the present invention may be located in the center in the diameter direction of the body part, and may not be located in the center in the diameter direction of the body part.

  A known material can be used as the material of the container body 2, for example, polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polyamide (PA), polystyrene (PS), ethylene-vinyl alcohol copolymer. (EVOH), elastomer, polyoxymethylene (POM), silica, glass, metal foil, or a composite material thereof. Of these, olefin resins such as PE and PP are preferred.

As shown in FIGS. 1 to 3, the cap 3 includes a disk-shaped top plate portion 18, an inner cylindrical portion 20 projecting downward from the top plate portion 18, and a peripheral edge of the top plate portion 18, that is, the top plate portion 18. And an outer cylindrical portion 22 that protrudes downward from the outside of the inner cylindrical portion 20. The ratio of the length from the bottom surface of the top plate portion 18 of the inner tube portion 20 to the lower end portion of the inner tube portion and the length from the bottom surface of the top plate portion 18 of the outer tube portion 22 to the lower end portion of the outer tube portion is 1: It is preferable that it is 1-1: 5.
In the state where the cap 3 is attached to the upper part of the container body 2, the lower end 22a of the outer cylinder part 22 may be in contact with the shoulder 12 of the container body 2 or may not be in contact with it. Is preferred.

The inner diameter of the distal end portion of the inner cylinder portion 20 is substantially the same as the outer diameter of the neck portion 14 of the container body 2, and the neck portion 14 of the container body 2 is fitted inside the inner cylinder portion 20. .
In addition, a second locking portion is formed annularly in the circumferential direction of the inner cylindrical portion 20 so as to protrude from the inner peripheral surface 20a toward the neck portion 14 side at the distal end side (lower end portion) of the inner peripheral surface 20a of the inner cylindrical portion 20. 24 is formed.

The inner cylindrical portion 20 has flexibility, and is shown in FIG. 3 when the neck portion 14 of the container main body 2 is fitted into the inner cylindrical portion 20 of the cap 3 and the cap 3 is attached to the container main body 2. As described above, the first locking portion 16 and the second locking portion 24 form a locking structure.
Further, the outer cylindrical portion has a pressing portion pressed from a specific direction, and when the pressing portion is pressed inside the outer cylindrical portion, the lower end portion 22a of the outer cylindrical portion 22 rises from the surface of the shoulder portion 12, The cap 3 is pushed up, and the engagement state between the first locking portion 16 and the second locking portion 24 is released.
The vertical cross-sectional shape of the second locking portion 24 is triangular in this example, but it can form an engagement structure with the first locking portion 16 and is in an engaged state when the cap is pushed up. As long as the shape is canceled, the shape is not limited to a triangular shape, and may be a semicircular shape, a rectangular shape, or the like. It is preferable that the longitudinal cross-sectional shapes of the first locking part 16 and the second locking part 24 are both triangular.

At the center of the top plate portion 18 of the cap 3, a through hole 25 communicating with the inner cylinder portion 20 is formed, and a cylindrical spout portion 26 protruding upward is provided so as to surround the through hole 25. A sleeve 28 that protrudes downward from the inner side than the inner cylindrical part 20 in the top plate part 18 is provided.
In the container 1, the contents accommodated in the body portion 10 of the container body 2 are poured out from the spout portion 26 through the shoulder portion 12, the neck portion 14, the sleeve 28, and the through hole 25.

  The sleeve 28 has a tip 28 a that abuts against the upper surface of the tip 14 b of the neck 14. Thereby, it can suppress easily that the content leaks in the state which attached the cap 3. FIG. Further, as the sleeve 28, a known form such as an inner ring can be adopted in addition to the form that hits the neck 14 as described above.

  The cap 3 is further provided with a closing portion 32 that is formed through the top plate portion 18 and the hinge portion 30 and closes the through hole 25 so as to be freely opened and closed. On the opposite side of the hinge portion 30 in the closing portion 32, a finger hook portion 34 protruding outward is formed. The opposite side of the hinge part 30 means the side facing the hinge part with the inner cylinder part 20 in between. The finger hook portion 34 may be formed over the entire circumference of the closing portion 32 except for the hinge portion 30.

A concave portion 36 that is recessed inside the cap may be formed in a portion corresponding to the finger hook portion 34 on the outer peripheral surface 22 b of the outer cylindrical portion 22. Thereby, it becomes easy to put the finger on the finger hook 34 and open the closing portion 32.
The closing portion 32 may be provided with a protruding portion 38 that protrudes downward from the center of the lower surface. The protruding portion 38 is fitted into the spout portion 26 when the closing portion 32 is closed, and prevents the contents from leaking. In other words, the cap 3 closes the spout portion 26 by a so-called inner boss method. The shape of the protrusion may be trapezoidal, semicircular or inner ring.
The ratio of the inner diameter of the spout portion 26 to the inner diameter of the neck portion 14 is preferably 1: 0.1 to 1: 5.

The hinge mechanism of the hinge part 30 is not particularly limited, and for example, a one-point type, a two-point type, a three-point type, a butterfly type, a snap hinge type, a spring fitting type, or the like can be adopted.
The content leakage prevention mechanism by the closing portion 32 is not limited to the inner boss method by the protruding portion 38, and may be appropriately selected according to the content. For example, it may be an inner ring system in which a cylindrical part protruding from the lower surface of the closing part fits into the spout part, and the spout part fits into the cylindrical part protruding from the lower surface of the closing part, and An undercut method or the like in which engaging portions formed respectively on the inner peripheral surface of the cylindrical portion and the outer peripheral surface of the spout portion may be engaged.

The shape when the cap 3 is viewed from above is not particularly limited, and examples thereof include a circle, a polygon, an ellipse, and a star.
The material which comprises a cap will not be specifically limited if it is the material normally used for a cap, For example, PP, PE, PA, PET, PS, a metal, or these composite materials etc. are mentioned. Of these, olefin resins such as PE and PP are preferred. Specifically, when the material of the container body 2 is HDPE, the material of the cap 3 is preferably PP.

As shown to FIG. 4A, the outer side cylinder part 22 has pressing part 22 'pressed from a specific direction. The position of the pressing part 22 ′ is preferably on both ends in the Y direction. The same thickness may be sufficient as the hinge part 30 side in the inner side cylinder part 20, and the opposite side, ie, the X direction both ends, and may differ.
In the container 1, as shown to FIG. 4B, the hinge part 30 side in the inner side cylinder part 20 and the opposite side, ie, the both ends of a X direction, may be partially thickened. Thereby, the inner side cylinder part 20 becomes difficult to bend in the X direction rather than the Y direction. Therefore, in the container 1, when the outer cylindrical portion 22 is pressed inward along the X direction, the first engagement is greater than when the outer cylindrical portion 22 is pressed inward along the Y direction perpendicular to the X direction. The engagement state between the stop portion 16 and the second locking portion 24 is difficult to be released. Here, the pressing portion is configured on both ends of the outer cylindrical portion 22 in the Y direction so that the outer cylindrical portion 22 can be pressed in the Y direction.
4B, the ratio of the outer diameter in the X direction and the outer diameter in the Y direction of the inner cylindrical portion 20 is preferably (1: 2 to 1: 0.5).
In FIG. 4B, the ratio of the thickness in the X direction and the thickness in the Y direction in the inner cylinder portion 20 is preferably 5: 1 to 1: 1.

Hereinafter, the operation of the container 1 will be described.
Each time the container 1 is used, the user can arbitrarily select the opening format as desired. Specifically, for example, by grasping the outer cylindrical portion 22 of the cap 3, hooking a finger on the finger hook portion 34 and opening the closing portion 32, the contents can be poured out from the spout portion 26 and used. .

  When the closing portion 32 is opened in this way, the outer cylindrical portion 22 of the cap 3 is often gripped on the hinge portion 30 side and the opposite finger hook portion 34 side, and the outer cylindrical portion 22 extends along the X direction. It is easy to apply a pressing force to the inside. However, in the container 1, even when the outer cylindrical portion 22 is pressed inward along the X direction when the closing portion 32 is opened, the inner cylindrical portion 20 can be more difficult to bend in the X direction than in the Y direction. The engagement state of the one locking part 16 and the second locking part 24 can be made difficult to be released. Therefore, it is possible to prevent the cap 3 from being unexpectedly removed when the closing portion 32 is opened.

  In addition, by pressing the opposite portion in the Y direction in the outer cylindrical portion 22 inward along the Y direction, the lower end portion 22a of the outer cylindrical portion 22 rises on the surface of the shoulder portion 12, and the cap 3 is pushed up. Thus, the engaged state between the first locking portion 16 and the second locking portion 24 is released. Thus, in the container 1, the cap 3 can be easily detached from the container body 2 with one touch. In particular, when the remaining amount of the contents is reduced, the cap 3 can be removed by such a one-touch method, so that the contents can be used up easily.

The manufacturing method of the container 1 is not specifically limited. The shoulder 12 and the neck 14 can be integrally formed by, for example, compression molding, injection molding, blow molding, or the like. The cap 3 can be formed by injection molding or the like.
For example, a laminated cylinder forming the barrel 10 is attached to the lower end of the shoulder 12 of the molded body in which the shoulder 12 and the neck 14 are integrated, and the contents are filled into the barrel 10 from the bottom. Later, the bottom part is sealed and sealed, and the method of setting it as the container 1 by attaching the cap 3 is mentioned.

  The contents stored in the container 1 are not particularly limited. For example, dentifrice, food (pasteurized wasabi, paste, etc.), medicine (ointment, etc.), quasi-drug (skin cream, champulins, etc.) .)) And the like. Depending on the type of contents, the closing portion 32 may be formed wide so that the container 1 can be inverted. The ratio between the outer diameter of the closing portion 32 and the outer diameter of the body portion 10 when enabling the inversion is preferably 1: 1 to 1: 5. Thereby, the container 1 can be inverted stably.

  In the container 1 described above, the user can easily select the unsealing method according to his / her preference, and the contents can be used up easily. Moreover, it can suppress stably that a cap removes unexpectedly.

(Other embodiments)
In the container of the present invention, the aspect in which the inner cylindrical portion 20 is less likely to bend in the X direction than in the Y direction is not limited to the aspect like the container 1.
For example, as shown in FIG. 5A, slits 40 are formed in the axial direction of the inner cylinder part 20 on the side surface part 20b excluding the hinge part 30 side and the opposite part 20c of the inner cylinder part 20, and the inner cylinder part 20 is formed. It is good also as a container which has the cap 3A which formed the part 20c of the hinge part 30 side and the other side, and the part 20d of the side surface shorter in the circumferential direction than them. The number of slits is preferably 2-12. The ratio between the width and length of one slit is preferably 1: 1 to 1:10.

  In the cap 3 </ b> A, the inner cylinder portion 20 has a Y-direction in which the length in the circumferential direction of the hinge portion 30 side and the opposite portion 20 c in the inner cylinder portion 20 is longer than the circumferential length of the side portion 20 d. It is more difficult to bend in the X direction than the direction. That is, the pressing part is configured to be located at both ends in the Y direction. Therefore, when the outer cylinder part 22 is pressed inward along the X direction, the first locking part 16 and the second locking part 16 are more than when the pressing part of the outer cylinder part 22 is pressed inward along the Y direction. The engagement state of the locking part 24 is difficult to be released. The ratio of the circumferential length of the hinge portion 30 side and the opposite portion 20c to the circumferential length of the side portion 20d is preferably 1: 1 to 1: 0.1.

When forming a slit in the inner cylinder part 20, the height of the slit formed in the hinge part 30 side in the inner cylinder part 20 and the opposite side, that is, both ends in the X direction is formed in the side part 20b on both ends in the Y direction. The inner cylinder part 20 may be less likely to bend in the X direction than in the Y direction by making it lower than the height of the slit. As shown in FIG. 5B, when the cap 3 is divided into four at 45 ° and 135 ° in the X direction, the X direction both ends and the Y direction both ends are regions perpendicular to the Y direction (with diagonal lines). The region perpendicular to the X direction (no hatching) is defined as the X direction both ends.
The width of the slit may be the same or different, but the width of the slit formed in the side surface portion 20b on both ends in the X direction is made narrower than the width of the slit formed on both ends in the Y direction. The cylindrical portion 20 may be less likely to bend in the X direction than in the Y direction.
Moreover, when forming a slit, the slit may have reached the lower end part of the inner side cylinder part 20, and does not need to reach.

Further, as shown in FIG. 6, a container having a cap 3 </ b> B in which columnar reinforcing portions 42 for holding the shape of the inner cylinder portion 20 are provided on the outer sides of both ends in the X direction of the inner cylinder portion 20. Good.
In the cap 3B, the reinforcing part 42 is partially provided on both ends in the X direction of the inner cylindrical part 20, and the reinforcing part is not provided on both ends in the Y direction. Therefore, the inner cylindrical part 20 is more in the X direction than in the Y direction. Hard to bend. Therefore, when the outer cylinder part 22 is pressed inward along the X direction, the first locking part 16 and the second latching part 16 are compared with when the pressing portion of the outer cylinder part 22 is pressed inward along the Y direction. The engagement state of the locking portion 24 is difficult to be released.
The height of the reinforcing part 42 may be the same as or different from the inner cylinder part 20. The reinforcing portion 42 is preferably provided on the outer peripheral surface of the inner cylindrical portion 20 from the hinge portion 30 side and the opposite side. Specifically, when the surface area of the outer peripheral surface of the inner cylindrical portion 20 is 100 area%. , And preferably 5 to 100% by area. In FIG. 6, it is preferable that the ratio of the thickness of the reinforcement part 42 and the thickness of the inner cylinder part 20 is 1: 0.1 to 1:10.

  When a reinforcement part is provided partially outside the inner cylinder part, the aspect of the reinforcement part is not limited to the aspect of the cap 3B. For example, as shown in FIG. 7, a cap 3 </ b> C provided with a plate-shaped reinforcing portion 42 </ b> A having an arc-shaped cross section that surrounds both ends of the inner cylindrical portion 20 in the X direction. The height of the reinforcing portion 42A may be the same as or different from that of the inner cylindrical portion 20. The reinforcing portion 42A is preferably provided so as to surround the outer peripheral surface of the inner cylindrical portion 20 from the hinge portion 30 side and the opposite side. Specifically, when the outer peripheral surface of the inner cylindrical portion 20 is 100 area%. It is preferable to provide 5 to 100% by area. In FIG. 7, the ratio of the thickness of the reinforcing portion 42A and the thickness of the inner cylinder portion 20 is preferably 1: 0.1 to 1:10. Further, as shown in FIG. 8, a cap 3D provided with a plurality of rib-shaped reinforcing portions 43B so as to protrude outward in the diameter direction of the inner cylinder portion 20 from both ends of the inner cylinder portion 20 in the X direction. Good. The height of the rib-shaped reinforcing portion 43B may be the same as or different from that of the inner cylindrical portion 20. The rib-shaped reinforcing portion 43B is preferably provided so as to protrude outward from the inner cylindrical portion 20 toward the hinge portion 30 side and the opposite side. The number of rib-shaped reinforcing portions 43B is preferably 1 to 6.

Moreover, the container 1A which has the container main body 2 illustrated in FIG. 9 and the cap 3E attached to the upper end part of the container main body 2 may be sufficient. The same parts as those of the container 1 in the container 1A are denoted by the same reference numerals, and description thereof is omitted.
In the cap 3 </ b> E, the spout portion 26 is not formed around the central through hole 25 of the top plate portion 18, and the neck portion 14 of the container body 2 passes through the through hole 25 and protrudes above the top plate portion 18. It is like that. Further, the opening of the neck portion 14 protruding above the top plate portion 18 is closed by the closing portion 32 formed through the top plate portion 18 and the hinge portion 30.

A container provided with a cap whose length d1 from the projecting end to the projecting end is longer than the length d2 from the inner peripheral surface 20a of the inner cylindrical portion 20 of the engaging portion 24b (weak engaging portion) on both ends in the Y direction to the projecting end. is there.
The ratio of d1 to d2 is preferably 1: 1 to 5: 1.
The same parts as the container 1 in the container are denoted by the same reference numerals, and description thereof is omitted.

  For example, the caps other than the second locking part 24A can adopt the same aspects as the caps 3, 3 ′, 3A to 3D described above, and the inner cylindrical part 20 is not partially thickened. You may employ | adopt the cap of the aspect similar to the cap 3 except thickness being uniform.

  In the container of the present embodiment, the length d1 of the locking portion 24a on both ends in the X direction of the second locking portion 24A is longer than the length d2 of the locking portion 24b on both ends in the Y direction. The engaging strength of the locking structure at both ends in the X direction between the locking portion 16 and the second locking portion 24A is stronger than the engaging strength of the locking structure at both ends in the Y direction. Thereby, similarly to the container 1, when the outer cylinder part 22 is pressed inward along the X direction, the first locking part 16 is more than when the outer cylinder part 22 is pressed inward along the Y direction. And the engagement state of the second locking portion 24A is difficult to be released. Therefore, similarly to the container 1, the user can easily select an opening method according to his / her preference, and the contents can be used up easily, and the cap can be prevented from being removed unexpectedly.

(Other embodiments)
In addition, the aspect which makes the engagement strength of the locking structure of the X direction both ends of the 1st locking part and the 2nd locking part stronger than the engagement strength of the locking structure of the Y direction both ends was mentioned above. The embodiment is not limited. For example, the first locking portion and the second locking portion can be different from each other by making the shape of the locking portion on both ends in the X direction of the second locking portion different from the shape of the locking portion on both ends in the Y direction. The engaging strength of the locking structure at both ends in the X direction of the locking portion may be stronger than the engaging strength of the locking structure at both ends in the Y direction.
Specifically, for example, as shown in FIGS. 11A and 11B, the cross-sectional shape of the locking portion 24c on both ends in the X direction is triangular, and the cross-sectional shape of the locking portion 24d on both ends in the Y direction is semicircular. Examples include the second locking portion 24B having a stronger engagement strength in the X direction than in the Y direction. The ratio of the circumferential length of the triangular locking portion 24c at both ends in the X direction to the circumferential length of the semicircular locking portion 24d at both ends in the Y direction is 1: 1 to 1: 5. Preferably there is.
Also, in the case of an aspect in which the engagement strength of the locking structure at both ends in the X direction of the first locking portion and the second locking portion is stronger than the engagement strength of the locking structure at both ends in the Y direction, You may employ | adopt the aspect which the front-end | tip part of the neck part of a container main body protrudes above the top-plate part of a cap, and is closed by a closing part like the cap 3E.
The engagement strength is the compressive strength from the lateral direction and can be measured by a method using a compression tester. Specifically, the cap is compressed at a speed of 100 mm / min from the X direction and the Y direction, and the strength at which the cap is removed is measured.

[Third embodiment]
In the container of the present invention, it is also preferable that the outer cylindrical portion be less likely to bend in the X direction than in the Y direction. As a result, even when the outer cylinder part is pressed inward along the X direction, the lower end part of the outer cylinder part is unlikely to rise up the shoulder surface of the container body, and the outer cylinder part is pressed inward in the Y direction. The engagement state of the first locking portion and the second locking portion is less likely to be released than when it is done.
Hereinafter, an example of the container of the above aspect will be shown and described.

As shown in FIG. 12, the container of the present embodiment has a cap having an outer cylindrical portion 22A in which both end portions in the X direction of the outer cylindrical portion 22A are partially thickened and are less likely to bend in the X direction than in the Y direction. 4. In the outer cylindrical portion 22A, the shape of the inner peripheral surface 22c is an ellipse that is long in the Y direction, so that both ends in the X direction of the outer cylindrical portion 22A are partially thickened.

  As the cap 4, both ends in the X direction of the inner cylinder part 20 are partially thickened, except that both ends in the X direction of the outer cylinder part 22A are partially thickened. A mode similar to that of the cap 3 can be adopted. Moreover, as the said container, the same aspect as the container 1 is employable except having the cap 4 instead of the cap 3. In the container of the present embodiment, the same parts as those of the container 1 are denoted by the same reference numerals and description thereof is omitted.

  In the container of the present embodiment, the outer cylindrical portion 22A is less likely to bend in the X direction than the Y direction, and therefore when the outer cylindrical portion 22A is pressed inward along the X direction, the lower end portion 22a of the outer cylindrical portion 22A is the container. It is difficult to lift the surface of the shoulder 12 of the main body 2. On the other hand, when the outer cylindrical portion 22A is pressed inward along the Y direction, the lower end portion 22a of the outer cylindrical portion 22A rises up from the surface of the shoulder portion 12 of the container body 2. Accordingly, when the outer cylindrical portion 22A is pressed inward along the X direction, the first locking portion 16 and the second locking portion are more than when the outer cylindrical portion 22A is pressed inward along the Y direction. The engagement state of the part 24 is difficult to be released. Therefore, similarly to the container 1, the user can easily select an opening method according to his / her preference, and the contents can be used up easily, and the cap can be prevented from being removed unexpectedly.

(Other embodiments)
In the container of the present invention, the aspect in which the outer cylindrical portion is less likely to bend in the X direction than in the Y direction is not limited to the aspect like the cap 4.

It is preferable to be formed. The height of the reinforcing part 48 may be the same as or different from the height of the inner cylinder part 20. The ratio of the thickness of the reinforcing part to the thickness of the inner cylinder part is preferably 1: 1 to 1: 5.
In the cap 4 </ b> C, the reinforcing portion 48 is partially provided on both ends of the outer cylindrical portion 22 in the X direction, so that the outer cylindrical portion 22 is less likely to bend in the X direction than in the Y direction. Therefore, when the outer cylindrical portion 22 is pressed inward along the X direction, the lower end portion 22a of the outer cylindrical portion 22 is unlikely to rise up the shoulder of the container body, and the outer cylindrical portion 22 is moved inward along the Y direction. The engagement state of the first locking part 16 and the second locking part 24 is less likely to be released than when the pressing is performed.

  When a reinforcement part is provided partially inside the both ends of the X direction of an outer side cylinder part, the aspect of a reinforcement part is not limited to the aspect of the cap 4C. For example, as shown in FIG. 17, a plurality of rib-shaped reinforcing portions 48 </ b> A are provided so as to protrude inward in the diameter direction of the inner cylindrical portion 20 from the inner peripheral surfaces of both end portions in the X direction of the outer cylindrical portion 22.
