Description

  The present invention relates to a container.

  A hinged cap is known as a cap for a tube container for containing a dentifrice or the like, and a bottle container for containing a cosmetic or the like. As a specific example of the hinge-type cap, the lower end of the cylindrical outer cylinder wall is fixed to the upper end of the container body by driving-type fitting, and is provided so as to close the upper end of the outer cylinder wall, and the central part And a cap provided with an upper lid portion that closes the spout via a hinge portion on the upper plate portion on which the spout for pouring the contents is formed. A container having such a hinge-type cap is excellent in usability because the upper lid portion can be easily opened with one hand. However, in the hinged cap, as the remaining amount of the content decreases, the cap becomes an obstacle and it becomes difficult to push the content. 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 are not used up.

  In view of this, a container has been proposed in which the hinge-type cap is screwed and fixed to the upper end of the container body by screwing (for example, Patent Documents 1 to 3). In the container, when the remaining amount of the content decreases, the content can be used up by removing the hinged cap from the container body. However, in the case of removing the hinged cap, the container needs to be rotated many times, which makes the removing operation of the cap complicated.

  In addition, when using up the contents whose remaining amount is reduced, the outer cylinder wall pushes up the shoulder portion of the container body by pressing the opposing portions of the outer cylinder wall of the hinge type cap inward, and the cap There is also proposed a container which is made to be detached (Patent Document 4). In the container, the cap can be removed from the container body without rotating the cap simply by pressing the opposing portions of the outer cylinder wall of the cap inward.

However, it is not assumed that the container of patent document 4 selects an opening system by preference every time a user uses it. That is, once the cap is removed from the container body, the cap can not be attached to the container body again.
Further, in the hinge type cap, when the hinge portion protrudes outside the body portion of the container main body in a plan view, the hinge portion is caught during use and difficult to handle. Therefore, in the hinged cap, in order to ensure good handleability, it is important to fit the hinge portion inside the outer edge of the upper end of the body portion of the container body in plan view. However, in a container such as Patent Document 4, when the position of the hinge part in plan view is to be stored inside the outer edge of the upper end of the body part, the outer diameter of the outer cylindrical wall is larger than the outer diameter of the upper end of the body part. It becomes smaller. As a result, the distance by which the outer cylinder wall lifts the shoulder of the container body is shortened, and the cap may not be easily removed by the cap being not sufficiently pushed up with respect to the container body.

  An object of the present invention is to provide a container in which a user can select an opening method according to preference, and the content can be easily used up, and the container is compatible with excellent handleability and ease of cap removal.

It has a notched shape, and a straight or curved notch side in the upper plate portion and the upper lid portion are hinged portions. Connected, the first engaging portion is provided on the outer peripheral surface of the neck portion, the second engaging portion is provided on the inner peripheral surface of the inner cylindrical wall, and the cap is attached to the container body In this state, the neck portion fits inside the inner cylindrical wall, and an engagement structure is formed by the first engagement portion and the second engagement portion. When the opposite portion of the outer cylinder wall is pressed inward in the radial direction, the lower end of the outer cylinder wall rises in contact with the shoulder, The engagement structure between the engagement portion and the second engagement portion is released.

In the container of the present invention, it is preferable that the outer cylinder wall is gradually expanded in diameter downward.
Further, it is preferable that a bottom surface of the outer cylinder wall in a bottom view shape is a broken circular shape in which the hinge portion side is broken in a linear shape or a curved shape.
Further, it is preferable that the lower end of the rear wall portion vertically suspended from the cutout side of the upper plate portion in the outer cylinder wall is recessed upward. In this case, in the outer cylinder wall, a position at which the outer cylinder wall is pressed inward in the radial direction is a portion facing in the Y direction perpendicular to the X direction connecting the hinge and the opposite side in plan view. It is preferable that a pressing position display unit shown is provided.
In addition, when the shoulder is bent upwardly in a state where the cap is attached to the container body, the lower end of the outer cylindrical wall is made to prevent the lower end of the outer cylindrical wall from coming into contact with the shoulder. Preferably, it is spaced from the shoulder.

Hereinafter, an example of the container of this invention is demonstrated based on FIGS.
The container 1 of this embodiment is provided with the container main body 2 which accommodates the content, and the cap 3 detachably attached to the upper end part of the container main body 2, as shown to FIGS. The container 1 is a so-called tube container used for containing contents such as paste.

(Container body)
The container main body 2 is formed at the upper end of the trunk portion 10 that accommodates the contents, the upper end of the trunk portion 10, and inclined so as to gradually narrow upward, and protrudes from the upper end of the shoulder portion 12. And a cylindrical neck portion 14 whose upper end is open.

  On the outer peripheral surface of the neck portion 14, a first engaging portion 16 formed of an annular ridge protruding radially outward over the entire circumference of the neck portion 14 is provided. The longitudinal cross-sectional shape of the first engagement portion 16 is a triangular shape in this example, but is not limited to a triangular shape, and may be semicircular, rectangular or the like.

  The neck portion 14 has a large diameter portion 14 a formed below the first engagement portion 16 and having an outer diameter larger than that of other portions.

  An end seal portion 10 a extending in a direction orthogonal to the up-down direction is formed at the lower end of the body portion 10.

  As a material of the container main body 2, known materials can be used. For example, polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polyamide (PA), polystyrene (PS), ethylene-vinyl acetate copolymer (EVA), ethylene-vinyl alcohol copolymer (EVOH), elastomer, polyoxymethylene (POM), silica, glass, metal foil, or a composite material of these, and the like.

(cap)
As shown in FIGS. 3 to 7, the cap 3 includes an outer cylinder wall 18, an upper plate part 20, an inner cylinder wall 22, and an upper lid part 26. The upper plate portion 20 has a shape in which a part of a circle is cut in a straight line in a plan view, and a spout 20 a is formed in a central portion. The outer cylinder wall 18 is suspended from the outer edge of the upper plate portion 20. The inner cylindrical wall 22 is suspended from the upper plate portion 20 so as to surround the spout 20 a inside the outer cylindrical wall 18. The upper lid portion 26 is connected to the cutout side 20b of the upper plate portion 20 via the hinge portion 24 so as to close the pouring port 20a freely.

  In the outer cylindrical wall 18, the lower end 18 a is in contact with the shoulder 12 when the cap 3 is attached to the container body 2 and is pressed inward in the radial direction. The lower end 18a of the outer cylindrical wall 18 contacts the shoulder 12 and the lower end 18a of the outer cylindrical wall 18 lifts the shoulder 12 when the opposing portion of the outer cylindrical wall 18 is pressed radially inward. Then, the cap 3 is pushed up and removed from the container body 2.

The outer cylinder wall 18 is a broken circle in which the side of the hinge portion 24 in a circular shape in plan view is linearly broken. The front surface portion and the side surface portion of the outer cylindrical wall 18 are gradually expanded in diameter downward.
The back side portion of the outer cylinder wall 18 of the cap 3 is vertically suspended from the back side portion of the upper plate portion 20 with respect to the upper plate portion 20. Thus, the outer diameter of the rear wall 18b of the outer cylinder wall 18 does not change in the vertical direction. Thereby, the cap 3 can be manufactured at a lower cost without using a special mold.

As shown in FIG. 6, the bottom view shape of the lower end 18 a of the outer cylindrical wall 18 is a circular shape with the circular hinge portion 24 side missing in a straight line.
As shown in FIG. 7, the lower end 18 a of the back wall portion 18 b that hangs perpendicularly from the cut-out side 20 b of the upper plate portion 20 in the outer cylindrical wall 18 is recessed upward along the shape of the shoulder portion 12. It has an arc shape.

When the opposing portion of the outer cylindrical wall 18 is not pressed inward in the radial direction, the lower end 18a of the outer cylindrical wall 18 has the shoulder 12 convexed upward with the cap 3 attached to the container body 2 It is preferably spaced from the shoulder 12 so that it does not contact the shoulder 12 when it is curved. Thereby, when the remaining amount of the contents is small, even if the shoulder portion 12 is curved upward, the cap 3 is unexpectedly removed by squeezing the upper end side portion of the body portion 10 of the container body 2. It can be suppressed.

As shown in FIG. 5, the outer cylindrical wall 18 is pressed radially inward at a portion of the outer cylindrical wall 18 opposed in the Y direction perpendicular to the X direction connecting the hinge portion 24 and the opposite side. A pressed position display unit 19 indicating the position is provided. In the present invention, when the shape of the outer cylinder wall in a plan view is the above-described notch shape, it is preferable to provide the pressed position display portion in a portion facing in the Y direction in the outer cylinder wall as in this embodiment.
When the shape of the outer cylinder wall in a plan view is a chipped shape with a missing hinge portion, pressing the portion facing the Y direction on the outer cylinder wall presses the portion facing the X direction on the outer cylinder wall. The outer cylinder wall tends to lift up the shoulder compared to the case. Therefore, the cap can be easily removed from the container main body by providing the pressed position display unit and urging the pressed position display unit to be pressed.

The pressing position display unit 19 in this example includes a plurality of ridges extending in the vertical direction and protruding outward from the outer surface of the outer cylindrical wall 18. The aspect of the pressing position display part 19 is not limited to the aspect which consists of several convex lines, You may form by printing etc. FIG.
The front view shape of the pressing position display unit 19 is substantially semicircular in this example. The front view shape of the pressed position display unit 19 may be rectangular or the like.

The plan view shape of the upper plate portion 20 is a shape in which the side of the hinge portion 24 in a circle is linearly broken. As described above, in the cap 3, the shape of the upper plate portion 20 in a plan view is formed such that the hinge portion 24 side is missing, so that the hinge portion 24 has an outer edge at the upper end of the body portion 10 of the container body 2 in the plan view. To fit inside. Thereby, it is possible to suppress that the hinge portion 24 is caught and difficult to handle at the time of use, storage, transport and the like.
In addition, by adopting such a shape in which the side of the hinge portion 24 is missing in the upper plate portion 20, it is not necessary to change the size of the filling facility of the contents, and the filling of the contents becomes easy. Further, in a plan view, the radius of the front surface portion and the side surface portion of the outer cylindrical wall 18 is increased to be equal to the radius of the upper end portion of the trunk portion 10 while the hinge portion 24 is housed inside the outer edge of the upper end of the trunk portion 10. can do. Thereby, when the opposing part in the outer cylinder wall 18 is pressed to the inner side in the radial direction, the outer cylinder wall 18 rises up the shoulder portion 12 and the cap 3 is easily pushed up, so that the cap 3 can be It becomes easy to come off from the main body 2.

  Further, in a plan view, a portion of the upper plate portion 20 opposite to the hinge portion 24 has a shape in which a part of a circle is missing in a curved shape convex toward the outside in the radial direction by a concave portion 32 described later. Yes. Thus, the planar view shape of the whole upper board part 20 of this example is a substantially elliptical shape long to a Y direction.

  Further, in this example, as shown in FIG. 4, when assuming a state in which the hinge portion 24 side of the lower end 18 a of the outer cylindrical wall 18 is not chipped in a bottom view, a circular imaginary shape of the lower end 18 a of the outer cylindrical wall 18 is assumed. The hinge part 24 is located inside the line k. In the present invention, it is preferable that the hinge portion is positioned on the inner side of the circular imaginary line at the lower end when assuming that the hinge portion side at the lower end of the outer cylinder portion is not missing in the bottom view. Accordingly, it is possible to facilitate the removal of the cap by keeping the lower end of the outer cylinder part as close as possible to the outer edge of the upper end of the body part as much as possible while preventing the hinge part from being caught and difficult to handle during use.

  In the central portion on the inner side of the inner cylindrical wall 22 in the upper plate portion 20, a spout 20a having a circular shape in a plan view is formed. The diameter of the outlet 20 a is smaller than the diameter of the upper end opening 14 b in the neck 14.

As shown in FIG. 6, in this example, both sides of the inner cylindrical wall 22 in a direction (Y direction) orthogonal to the direction (X direction) connecting the opposite side from the hinge portion 24 in plan view in the upper plate portion 20. Openings 25 and 25 are respectively formed at positions closer to the outer cylinder wall 18 of the above. By forming the openings 25 and 25, even if water gets into the inside of the outer cylinder wall 18 on the shoulder 12, it is easy to dry, and therefore the mold on the shoulder 12 is hard to grow. Further, by forming the openings 25 25 at the above-described position in the upper plate portion 20, filling of the openings 25 25 by contents coming out of the pouring cylinder portion 23 described later during use is suppressed .
The planar view shape of the openings 25 and 25 is circular in this example. In addition, the planar view shape of the openings 25 and 25 is not limited to a circular shape, and may be a triangular shape, a rectangular shape, or the like.

The bending rigidity of the upper plate portion 20 is preferably higher than the bending rigidity of the outer cylinder wall 18. Thereby, when pressing the opposing part in the outer cylinder wall 18 to the inner side of radial direction, it suppresses that the upper board part 20 deform | transforms with the deformation | transformation of the outer cylinder wall 18, and the upper cover part 26 opens unexpectedly. it can.
The aspect in which the bending rigidity of the upper plate portion 20 is made higher than the bending rigidity of the outer cylindrical wall 18 is not particularly limited, and the aspect in which the thickness of the upper plate portion 20 is made thicker than the thickness of the outer cylindrical wall 18. The aspect which forms the upper board part 20 with the material from which a bending rigidity becomes high rather than the material which forms, the aspect which provides a rib in the upper board part 20, and is reinforced is mentioned. Among them, an aspect in which the thickness of the upper plate portion 20 is thicker than the thickness of the outer cylinder wall 18 is preferable in terms of easy production.

  The inner cylinder wall 22 is provided so as to extend downward from the inner side than the outer cylinder wall 18 in the upper plate portion 20. The inner cylinder wall 22 is cylindrical. The inner diameter of the inner cylindrical wall 22 is substantially equal to the outer diameter of the neck portion 14 of the container main body 2, and the neck portion 14 of the container main body 2 is fitted inside the inner cylindrical wall 22.

It is preferable that one or more notches extending upward from the lower end of the inner cylinder wall are formed in the inner cylinder wall in the circumferential direction. As a result, the inner cylinder wall is easily bent, so that it is easy to engage the first engagement portion with the second engagement portion described later by fitting the neck portion of the container body inside the inner cylinder wall. Become. The number of cutouts formed in the inner cylinder wall is not particularly limited, and may be one or more.
The notch formed in the inner cylinder wall may have a slit shape.

A second engaging portion 28 made of an annular ridge that extends over the entire circumference in the circumferential direction of the inner circumferential surface 22a and protrudes inward in the radial direction is provided at a portion near the lower end of the inner circumferential surface 22a of the inner cylindrical wall 22. It is provided.
The inner cylinder wall 22 has flexibility, and when the neck portion 14 is fitted inside the inner cylinder wall 22 of the cap 3 and the cap 3 is attached to the container body 2, the first engaging portion 16 and The second engagement portion 28 is adapted to form an engagement structure. Specifically, the engagement structure is formed by the second engagement portion 28 being hooked and latched below the first engagement portion 16. Thereby, it is controlled that the cap 3 attached to the container main body 2 moves upward, and the cap 3 is prevented from being unexpectedly removed.

  In a state where the cap 3 is attached to the container main body 2, when the opposing portion of the outer cylinder wall 18 is pressed inward in the radial direction, the outer cylinder wall 18 lifts the shoulder 12 and the first engagement portion 16 When the engagement structure is released by the second engagement portion 28, the cap 3 is pushed up and detached from the container body 2.

The longitudinal cross-sectional shape of the second engaging portion 28 is a triangular shape in this example, but is not limited to a triangular shape, and may be semicircular, rectangular or the like.

  Inside the inner cylinder wall 22 on the lower surface of the upper plate portion 20, a cylindrical sleeve 21 suspended from the peripheral edge of the spout 20a is provided. In a state in which the cap 3 is attached to the neck 14 of the container body 2, the sleeve 21 acts as an inner ring that is liquid-tightly inserted inside the upper end opening 14 b of the neck 14. Thereby, in a state where the cap 3 is attached to the container main body 2, leakage of the contents from the neck portion 14 to the shoulder portion 12 below the upper plate portion 20 is suppressed.

  On the inner side of the inner cylindrical wall 22 on the upper surface of the upper plate portion 20, a cylindrical spout cylinder portion 23 protruding upward from the peripheral edge of the spout 20a is provided. In the container 1, the contents accommodated in the container body 2 are poured out from the neck portion 14 through the sleeve 21 and the spout 20 a from the spout cylinder portion 23.

  The hinge mechanism of the hinge portion 24 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.

At a central portion of the upper lid portion 26, an annular protrusion 30 suspended from the lower surface of the upper lid portion 26 is provided. In a state where the cap 3 is attached to the container main body 2, the tip end of the pouring-out tube portion 23 protruding upward from the upper plate portion 20 is fitted into the annular protrusion 30. In other words, the upper lid portion 26 is configured to open and close the pouring cylinder portion 23 communicating with the pouring port 20a by a so-called outer ring method. Thereby, leakage of the contents is suppressed in the state in which the upper cover 26 is closed.
In the container of the present invention, an inner ring system may be adopted, and an inner boss system may be adopted.

A concave portion 32 that is recessed inward in the radial direction is formed in a front surface portion of the upper lid portion 26 and the outer cylindrical wall 18 opposite to the hinge portion 24, and a front end portion of the upper lid portion 26 is a finger hook portion 34. It is said that. Accordingly, the upper lid portion 26 can be easily opened by placing a finger on the finger hook portion 34.
The recess 32 in this example is formed so as to be recessed radially inward as it extends upward from the lower end 18 a of the outer cylinder wall 18 and inward as it extends downward from the upper end of the upper lid 26. Yes.
The shape and size of the recess 32 are not particularly limited, and can be appropriately set according to the size of the cap 3 and the like.

As shown in FIG. 7, in this example, openings 27 and 27 are respectively formed on both sides of the hinge portion 24 in the back surface portion of the upper lid portion 26. As a result, the gap between the shoulder 12 and the lower end 18a of the outer cylinder wall 18 is formed inside the outer cylinder wall 18 on the shoulder 12, the openings 25 and 25 formed in the upper plate part 20, and the upper lid part 26. There is an air path leading to the openings 27, 27. Therefore, since the drying speed when water gets into the inside of the outer cylinder wall 18 on the shoulder 12 becomes faster, it becomes more difficult for mold to grow on the shoulder 12.
The front view shape of the openings 27, 27 is rectangular in this example. The plan view shape of the openings 27 and 27 is not limited to a rectangular shape, and may be a circular shape, a triangular shape, or the like.

  The material of the cap 3 is not particularly limited as long as it is a material generally used for the cap, and examples thereof include PP, PE, PA, PET, PS, metals, composite materials of these, and the like.

(Production method)
The method for producing the container 1 is not particularly limited. For example, a laminate cylinder forming the body 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, the cap 3 is attached to the neck 14, and the cap 3 is attached The method of making it the container 1 by filling up the contents from the bottom of a cylinder in the state which turned down, sealing a bottom, and sealing body part 10 is mentioned.
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.

(Contents)
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.

(Action effect)
As described above, in a container such as Patent Document 4, it is not assumed that the user selects the opening method according to his / her preference every time he / she uses, and once the cap is removed from the container body, the cap is removed. It cannot be attached to the container body again. In addition, in order to ensure good handleability, if the position of the hinge portion in plan view is to be stored inside the outer edge of the upper end of the body portion, the outer diameter of the outer cylindrical wall of the cap becomes smaller, so The distance by which the barrel wall lifts the shoulder of the container body is short, making it difficult to remove the cap.

On the other hand, in the case of the container 1, the user can arbitrarily select the opening format according to his / her preference each time the container 1 is used. Specifically, for example, as shown in FIG. 2, the upper end portion 26 of the barrel body 2 in the container body 2 is grasped, the finger is hooked on the finger hook portion 34, and the upper lid portion 26 is opened. The contents can be poured out and used.
Further, the lower end 18a of the outer cylindrical wall 18 rises up from the surface of the shoulder 12 by pressing a portion of the pressing position display portion 19 facing the Y direction on the outer cylindrical wall 18 inward in the radial direction. Is pushed up to release the engagement between the first engagement portion 16 and the second engagement portion 28. Thus, in the container 1, the cap 3 can be easily detached from the container body 2 with one touch. Furthermore, the cap 3 once removed can be reattached by fitting into the neck portion 14 of the container body 2 and engaging the first engagement portion 16 and the second engagement portion 28.
In the container 1, particularly when the remaining amount of the content decreases, the cap 3 can be removed by such a one-touch type, so that the content can be easily used up.

In the container 1, the radius of the front surface portion and the side surface portion of the outer cylindrical wall 18 of the cap 3 is set to the trunk portion 10 even when the position of the hinge portion 24 in a plan view is stored inside the outer edge of the upper end of the trunk portion 10. Can be almost equal to the radius of. Therefore, in the front and side portions of the outer cylinder wall 18, the distance by which the shoulder portion 12 of the container body 2 is lifted when pressed radially inward is sufficiently long. As a result, the cap 3 is pushed up sufficiently sufficiently relative to the container body 2 to release the engaged state of the first engagement portion 16 and the second engagement portion 28, and the cap 3 is released. It becomes easy to remove.
As described above, in the container 1, it is possible to suppress that the hinge portion 24 is caught and difficult to handle at the time of use, and it is also easy to remove the cap 3 by pressing inward facing portions in the outer cylinder wall 18.

  As described above, in the container of the present invention, the user can select the opening method according to the preference, it is easy to use up the contents, and both the excellent handleability and the ease of removing the cap are compatible.

The container of the present invention is not limited to the container 1 described above.
For example, in the container of the present invention, the shape of the upper plate portion in plan view may be a shape in which a part of the circle on the hinge portion side is cut in a curved shape. In this case, it is preferable that the hinge portion side in the circle has a curved shape that is concaved inward in the radial direction. In addition, the hinge part side in a circle | round | yen may be made into the shape which curvilinearly chipped so that it might become convex toward the outer side of radial direction.
Further, the shape in plan view of the outer cylinder wall and the shape in bottom view of the lower end of the outer cylinder wall may be a missing circle in which the hinge portion side in the circle is cut in a curved shape. In this case, the plan view shape of the outer cylinder wall and the bottom view shape of the lower end of the outer cylinder wall are not circular in a curved shape so that the hinge portion side of the circle is recessed toward the inside in the radial direction. Is preferred. The plan view shape of the outer cylinder wall and the bottom view shape of the lower end of the outer cylinder wall are not circular in a curved shape so that the hinge part side of the circle is convex outward in the radial direction. Also good.
Moreover, the outer cylinder wall does not need to gradually expand in diameter downward.

Moreover, the bottom view shape of the lower end of the outer cylinder wall in the cap is not limited to a broken circular shape in which the hinge portion side is broken in a linear shape or a curved shape, and may be a circular shape. Specifically, for example, the container 4 illustrated in FIGS. 8 and 9 may be used. The same parts as in FIG. 3 and FIG. 4 in FIG. 8 and FIG.
The container 4 is the same as the container 1 except that it comprises a cap 3A having an outer cylinder wall 18A instead of the outer cylinder wall 18.

  The outer cylindrical wall 18A includes an upper end side portion 18c that vertically hangs down from the cutout side 20b of the upper plate portion 20 so that the back wall portion 18b extends linearly in the Y direction in plan view, and a lower end of the upper end side portion 18c. The outer cylindrical wall 18 is the same as the outer cylindrical wall 18 except that it includes a projecting portion 18d extending radially outward from the tip and a lower end portion 18e suspended from the tip of the projecting portion 18d so as to increase in diameter downward. . The bottom view shape of the lower end 18a in the outer cylinder wall 18 is circular. That is, the outer cylindrical wall 18A has a shape in plan view on the upper end side, a circular shape with the hinge portion side lacking in a straight line shape, and the shape in bottom view of the lower end 18a is circular. It is the same mode.

In the container 4, the bottom view shape of the lower end 18 a of the outer cylindrical wall 18 is circular, so that the outer cylindrical wall 18 can be obtained even when a portion of the outer cylindrical wall 18 facing the X direction is pressed inward in the radial direction. The lower end 18a on the side of the hinge portion 24 in the case 22 sufficiently lifts the shoulder 12 of the container main body 2. Therefore, compared with the container 1, it is easier to remove the cap 3A by pressing the portion of the outer cylinder wall 18 facing the X direction inward in the radial direction.
Also, in the container 4 as well as the container 1, the user can optionally select the opening format at the time of use, and the cap 3A is removed by one-touch operation when the remaining amount of the content decreases. It is easy to use up the contents and easy to handle when pouring out the contents.
However, as in the case of the cap 3, the back wall portion of the outer cylinder wall is cut from the back side of the upper plate portion to the upper plate portion in that the cap can be formed at lower cost without using a special mold. It is preferable that it hangs down perpendicularly.

  In the container of the present invention, the combination of the first engagement portion and the second engagement portion forming the engagement structure is the first engagement portion 16 and the second engagement portion in the containers 1 and 4. It is not limited to an aspect like part 28. For example, an engagement structure may be formed by forming a groove in the circumferential direction on the outer peripheral surface of the neck portion and fitting and engaging the second engagement portion made of a convex line of the cap in the groove. .

In the container according to the present invention, the bottom end of the outer cylinder wall may be in contact with the shoulder in a state in which the cap is attached to the container body when the bottom view shape of the lower end of the outer cylinder wall is circular. Good.
Moreover, the container which does not provide a press position display part in the part which opposes in the Y direction of an outer cylinder wall may be sufficient.
Further, as in the case of the container 4 illustrated in FIGS. 8 and 9, when the bottom surface of the lower end of the outer cylinder wall is circular, the position of the pressed position display portion is a portion facing in the Y direction of the outer cylinder wall. And may be any part of the outer surface of the outer cylinder wall.
The container of the present invention may be a container in which the bending rigidity of the upper plate portion in the cap is not higher than the bending rigidity of the outer cylinder wall.
