Description

  The present invention relates to a container.

  As a cap in a tube container for storing dentifrice or the like or a bottle container for storing cosmetics or the like, a hinge-type cap is known. 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 hinge-type 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 contents is low, the contents can be used up by removing the hinged cap from the container body. However, in the case of the container, it is necessary to rotate many times when the hinge-type cap is removed, and the removal of the cap is complicated.

  In addition, when the remaining content is used up, by pressing the opposing part of the outer wall of the hinged cap inward, the outer wall rises up the shoulder of the container body, and the cap A container that can be detached has also been proposed (Patent Document 4). The container can be detached from the container main body without rotating the cap by simply pressing the opposing portion of the outer cylinder wall of the cap inward.

Hereinafter, an example of the container of the present invention will be described with reference to FIGS.
The container 1 of this embodiment is provided with the container main body 2 which accommodates the content, and the cap 3 attached to the upper end part of the container main body 2 so that attachment or detachment is possible, as shown to FIGS. The container 1 is a so-called tube container used for storing contents such as a paste-like material.

(Container body)
The container body 2 is formed at the upper end of the body 10 for accommodating the contents, the upper end of the body 10, and inclined so as to squeeze upward for a while, and protrudes from the upper end of the shoulder 12. And a cylindrical neck portion 14 having an upper end opened.

  On the outer peripheral surface of the neck portion 14, a first engaging portion 16 made of an annular ridge projecting outward in the radial direction over the entire circumference of the neck portion 14 is provided. The vertical cross-sectional shape of the first engaging 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.

  The neck portion 14 has a large-diameter portion 14a formed below the first engaging 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 the material of the container 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 thereof.

(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 20a is formed in the center 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 20a 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, and closes the spout 20a so as to be freely opened and closed.

  In the outer cylinder wall 18, the lower end 18 a comes into contact with the shoulder portion 12 when the cap 3 is pressed radially inward with the cap 3 attached to the container body 2. When the opposing portions of the outer cylindrical wall 18 are pressed inward in the radial direction, the lower end 18a of the outer cylindrical wall 18 comes into contact with the shoulder portion 12, and the lower end 18a of the outer cylindrical wall 18 rises up the shoulder portion 12. Thus, the cap 3 is pushed up and detached from the container body 2.

The outer cylindrical wall 18 has a circular shape with a circular shape in plan view, with the hinge portion 24 side lacking in a straight line. The front surface portion and the side surface portion of the outer cylindrical wall 18 are gradually expanded in diameter downward.
A portion on the back surface side of the outer cylindrical wall 18 of the cap 3 is suspended vertically from the back surface portion of the upper plate portion 20 with respect to the upper plate portion 20. Thus, the outer wall diameter of the rear wall portion 18b of the outer cylindrical 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.

In a state in which 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 projects the shoulder 12 upward while the cap 3 is attached to the container body 2. It is preferable that the shoulder portion 12 is separated from the shoulder portion 12 so that the shoulder portion 12 does not come into contact with the curved portion. 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. Can be suppressed.
The distance between the lower end 18a of the outer cylindrical wall 18 and the shoulder portion 12 in a state where the opposing portion of the outer cylindrical wall 18 is not pressed radially inward is determined by the outer cylindrical wall 18 when the outer cylindrical wall 18 is pressed. It can be set as appropriate within the range in which the shoulder 12 is raised, and is determined by the balance between the fitting force of the first engaging portion 16 and the second engaging portion 28 described later. This distance can be 0-2.0 mm, for example.

As shown in FIG. 5, the outer cylinder wall 18 is pressed radially inward at a portion of the outer cylinder wall 18 facing the Y direction perpendicular to the X direction connecting the hinge portion 24 and the opposite side. A pressing position display unit 19 indicating the position is provided. In the present invention, when the shape of the outer cylinder wall in plan view is a notch shape as described above, it is preferable to provide a pressing position display part at a portion facing 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. Compared to the case, the outer cylinder wall tends to rise up the shoulder. For this reason, it is possible to easily remove the cap from the container body by providing a pressing position display unit and prompting the pressing 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 a some protruding item | line, You may form by printing etc.
The front view shape of the pressing position display unit 19 is substantially semicircular in this example. In addition, the front view shape of the pressing position display unit 19 may be a rectangular shape or the like.

The plan view shape of the upper plate portion 20 is a shape in which the hinge portion 24 side of the circle is lacking linearly. 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 can suppress that the hinge part 24 gets caught and becomes difficult to handle at the time of use, at the time of storage, at the time of transportation.
Further, by adopting such a shape in which the hinge portion 24 side is cut off in the upper plate portion 20, it is not necessary to change the size of the filling equipment for 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 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 entire upper plate portion 20 in this example is a substantially elliptical shape that is long in the 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.

  A spout 20a having a circular shape in a plan view is formed in a central portion inside the inner cylinder wall 22 in the upper plate portion 20. The diameter of the spout 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 the direction (Y direction) orthogonal to the direction (X direction) connecting the opposite side from the hinge part 24 in plan view in the upper plate part 20. Openings 25 and 25 are formed at positions close to the outer cylinder wall 18. Since the openings 25 and 25 are formed, even if water enters the inside of the outer cylindrical wall 18 on the shoulder portion 12, it is easy to dry, so that the shoulder portion 12 is less prone to mold. In addition, since the openings 25 and 25 are formed at the above-described positions in the upper plate portion 20, it is possible to suppress the openings 25 and 25 from being filled with the contents that have come out from the below-described dispensing cylinder portion 23 during use. .
The planar view shape of the openings 25 and 25 is circular in this example. The plan view shape of the openings 25, 25 is not limited to a circle, and may be a triangle, a rectangle, 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 in which bending rigidity becomes higher than the material which forms, the aspect which provides a rib in the upper board part 20, and reinforces etc. are mentioned. Especially, the aspect which makes thickness of the upper board part 20 thicker than the thickness of the outer cylinder wall 18 from a point with easy manufacture is preferable.

  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 notches formed in the inner cylinder wall is not particularly limited, and may be one or plural.
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. Is provided.
The inner cylindrical wall 22 has flexibility, and when the cap 3 is attached to the container body 2 by fitting the neck portion 14 inside the inner cylindrical wall 22 of the cap 3, The second engaging portion 28 forms an engaging 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.

  When the opposing portion of the outer cylindrical wall 18 is pressed inward in the radial direction with the cap 3 attached to the container body 2, the outer cylindrical wall 18 rises up the shoulder 12, and the first engaging 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 vertical 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 a semicircular shape, a rectangular shape, or the like.

  A cylindrical sleeve 21 suspended from the periphery of the spout 20a is provided on the inner surface of the lower surface of the upper plate portion 20 with respect to the inner cylindrical wall 22. In a state where the cap 3 is attached to the neck portion 14 of the container body 2, the sleeve 21 functions as an inner ring that is inserted in a liquid-tight manner inside the upper end opening portion 14 b of the neck portion 14. Thereby, in the state which attached the cap 3 to the container main body 2, it is suppressed that the content leaks from the neck part 14 to the shoulder part 12 under the upper board part 20. FIG.

  On the inner side of the upper surface of the upper plate portion 20 with respect to the inner cylinder wall 22, a cylindrical extraction cylinder portion 23 that protrudes upward from the peripheral edge of the spout 20 a is provided. In the container 1, the contents accommodated in the container main body 2 are poured out from the necking part 14 through the sleeve 21 and the spout 20a from the pouring cylinder part 23.

An annular protrusion 30 that hangs down from the lower surface of the upper lid portion 26 is provided at the center of the upper lid portion 26. In a state where the cap 3 is attached to the container body 2, the tip end portion of the extraction 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, it is suppressed that the content leaks in the state which closed the upper cover part 26. FIG.
In addition, in the container of this invention, an inner ring system may be employ | adopted and an inner boss system may be employ | 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 concave portion 32 in this example is formed so as to be recessed inward in the radial direction as it goes upward from the lower end 18a of the outer cylindrical wall 18, and so as to be recessed inward in the radial direction as it goes downward from the upper end of the upper lid portion 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, 27 are 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. Air passages leading to the openings 27 and 27 can be made. For this reason, the drying speed when water enters the inside of the outer cylindrical wall 18 on the shoulder portion 12 becomes faster, and thus the shoulder portion 12 becomes less prone to mold.
The front view shape of the openings 27, 27 is rectangular in this example. In addition, the planar view shape of the openings 27 and 27 is not limited to a rectangle, and may be a circular shape, a triangular shape, or the like.

  The material of the cap 3 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.

(Production method)
The manufacturing method of the container 1 is not specifically limited. For example, a laminated 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 to the neck 14. There is a method in which the contents are filled from the bottom of the cylinder in the state of being lowered, the bottom is sealed, and the body 10 is sealed to form the container 1.
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.

(Function and 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 that the cylindrical wall rises up the shoulder of the container body is shortened, and it is difficult to remove the cap.

On the other hand, in the case of using the container 1, the user can arbitrarily select the opening format according to his / her preference each time it 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 from 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, and the engagement state of the first engagement portion 16 and the second engagement portion 28 is released. 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, the cap 3 can be removed by such a one-touch method, particularly when the remaining amount of the content is low, so that the content can be used up easily.

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 surface portion and the side surface portion of the outer cylindrical wall 18, the distance to lift the shoulder portion 12 of the container body 2 is sufficiently long when pressed radially inward. As a result, the cap 3 is pushed up sufficiently sufficiently relative to the container body 2 to release the engagement state of the first engagement portion 16 and the second engagement portion 28, thereby It becomes easy to remove.
Thus, in the container 1, it can suppress that the hinge part 24 is caught and becomes difficult to handle at the time of use, and it is also easy to remove the cap 3 by pressing the opposing part in the outer cylinder wall 18 inside.

  As described above, in the container of the present invention, the user can select the opening method according to his / her preference, the contents can be used up easily, and excellent handling and easy removal of 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 missing in a curved shape. In this case, it is preferable that the circle has a shape lacking in a curved shape so that the hinge portion side is recessed toward the inside in the radial direction. In addition, you may make it the shape lacking in the curve shape so that the hinge part side in a circle may protrude toward the outer side of radial direction.
Moreover, the planar view shape of the outer cylinder wall and the bottom view shape of the lower end of the outer cylinder wall may be an oval shape in which the hinge portion side of the circle lacks 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 be expanded for a while toward the downward direction.

Moreover, the bottom view shape of the lower end of the outer cylinder wall in a cap is not limited to the missing circle shape which the hinge part side lacked in linear form or curved form, A circular shape may be sufficient. Specifically, for example, the container 4 illustrated in FIGS. 8 and 9 may be used. 8 and FIG. 9 that are the same as those in FIG. 3 and FIG.
The container 4 is the same as the container 1 except that the container 4 includes 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 hinge part 24 side sufficiently rises up the shoulder 12 of the container 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 case of the container 4, similarly to the container 1, the user can arbitrarily select the opening format when using it, and the cap 3 </ b> A can be removed by a one-touch type when the remaining amount of the contents is reduced. The contents can be used up easily and are easy to handle when pouring out the contents.
However, in the point that the cap can be molded at a lower cost without using a special mold, the back wall portion of the outer cylinder wall is changed from the notch side on the back side of the upper plate portion to the upper plate portion, like the cap 3. 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 the 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 of the present invention, when the bottom view shape of the lower end of the outer cylinder wall is circular, the lower end of the outer cylinder wall may come into contact with the shoulder with the cap attached to the container body. 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.
8 and 9, when the bottom shape of the lower end of the outer cylindrical wall is circular, the position of the pressing position display portion is the portion facing the Y direction of the outer cylindrical wall. However, it 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.
