Description

container

The present invention relates to a container.
Priority is claimed on Japanese Patent Application No. 2014-260413, filed Dec. 24, 2014, the content of which is incorporated herein by reference.

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 a drive-type fitting, and provided so as to close the upper end of the outer cylinder wall The top plate part in which the pouring outlet which pours out the contents in was formed, The cap provided with the upper cover part which closes the said pouring outlet via a hinge part is mentioned. A container provided with such a hinged cap is excellent in usability because it is easy to open the upper lid 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 out the content. In addition, since the hinged cap generally has a large volume, it tends to have an image that the contents remain inside the cap and are not used up.

Therefore, a container has been proposed in which the hinged cap is screwed and screwed on and fixed to the upper end portion of the container body (for example, Patent Documents 1 to 3). In the case where the content of the container is low, the content can be used up by removing the hinged cap from the container body. However, in the case of the above-mentioned container, when the remaining amount of the content decreases, it is necessary to rotate and remove the hinged cap many times, and the cap removing operation is complicated.

In addition, when using up the contents whose remaining amount is depleted, the outer cylinder wall pushes up the shoulder of the container body by pressing the opposing portions of the outer cylinder wall of the hinge type cap inward, and the cap There has also been proposed a container which is made to come off (Patent Document 4).
However, the container is not supposed to select the opening method by preference every time the 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.

In addition, as described above, when the volume of the hinge-type cap is increased, the content is likely to remain inside the cap and not be used up easily, so the pouring portion provided on the cap is located on the top of the container body. It tends to be smaller than the formed mouth and neck. Therefore, for example, in a tube container containing a dentifrice, it may be difficult to place the poured out contents on the toothbrush.

Japanese Patent Laid-Open No. 10-258853 JP, 2008-15596, A JP, 2010-275001, A Japanese Patent Application Publication No. 2003-12005

(cap)
As shown in FIGS. 3-8, the cap 3 has a cylindrical outer cylinder wall 18, an upper plate portion 20 extending inward from the upper end of the outer cylinder wall 18, and a through hole 20a formed therein, and an upper plate portion A projecting cylindrical portion 22 extending upward from the inner peripheral edge of 20 and an upper lid portion 26 formed via the upper plate portion 20 and the hinge portion 24 are provided.

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.

[Correction based on rule 91 05.04.2016]
The outer cylindrical wall 18 is a notched circular shape in which the side of the hinge portion 24 in a circular shape in a plan view is linearly broken, and the diameter is gradually enlarged downward. The bottom view shape of the lower end 18a of the outer cylindrical wall 18 is also a broken circle in which the side of the circular hinge portion 24 is linearly broken.
As described above, according to the present invention, the hinge portion can be held on the inside of the body portion of the container main body in a plan view by making the plan view shape and the bottom view shape of the outer cylinder wall a truncated circle with the hinge portion side missing. Thus, it is possible to prevent the hinge portion from being caught and difficult to handle at the time of use. In addition, it is not necessary to change the size of the content filling facility, and the content can be easily filled. In addition, by adopting such a circular shape, the radius of the front surface portion and the side surface portion in the outer cylinder wall is made equal to the radius of the upper end portion of the trunk while fixing the hinge to the inside of the trunk in plan view. It can be enlarged until it becomes. Thereby, when the opposing part in the outer cylinder wall is pressed inward in the radial direction, the outer cylinder wall tends to ascend the shoulder, and the cap is easily detached from the container main body.

When making the plan view shape and the bottom view shape of the outer cylinder wall into a broken circle with the hinge portion side missing, the size of the chipped portion in the outer cylinder wall in plan view is centered on the central axis of the outer cylinder wall It is preferable to set it in the range of 60 to 150 °.

The portion 18b on the hinge portion 24 side (back side) of the lower end 18a of the outer cylindrical wall 18 is a circle convex upward along the shape of the shoulder portion 12 when the portion is viewed from the front as shown in FIG. It is arc-shaped.

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. In the present invention, when the bottom surface shape of the lower end of the outer cylinder wall is a truncated circle with the hinge portion side missing, the outer cylinder wall is not in contact with the shoulder even if the shoulder is curved upward in this way Preferably, the lower end of is spaced from the shoulder. Thus, by squeezing the upper portion of the body portion of the container body when the remaining amount of the content is small, it is possible to suppress the cap from coming off unexpectedly even if the shoulder portion is bent upward.

The distance between the lower end of the outer cylinder wall and the shoulder when the opposing portion of the outer cylinder wall is not pressed radially inward is the range in which the outer cylinder wall lifts the shoulder when the outer cylinder wall is pressed It can be set appropriately within. The distance may be, for example, 0 to 2.0 mm. In the case where the lower end of the outer cylindrical wall is separated from the shoulder so as not to contact with the shoulder even if the shoulder is curved upward, the distance is preferably 0.1 to 1.0 mm.

As shown in FIG. 7, the outer cylindrical wall 18 is pressed radially inward to a portion of the outer cylindrical wall 18 that faces 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 plan view shape of the outer cylinder wall is a broken circular shape in which the hinge part side is missing, pressing the opposing portion in the Y direction in the outer cylinder wall presses the opposing portion in the X direction in 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 pressed position display portion 19 in this example is formed of a plurality of ridges extending in the vertical direction and projecting outward from the outer surface of the outer cylindrical wall 18. The aspect of the pressing position display unit is not limited to the aspect including a plurality of ridges, and may be formed by printing or the like.
The front view shape of the pressing position display unit 19 is substantially semicircular in this example. The front view shape of the pressing position display unit may be rectangular or the like.

The shape of the upper plate portion 20 in a plan view is a circular shape similar to that of the outer cylindrical wall 18, and a through hole 20a having a circular shape in a plan view is formed in a central portion. The diameter of the through hole 20 a is substantially equal to that of the large diameter portion 14 a of the neck portion 14. When the cap 3 is attached to the container body 2, the large diameter portion 14 a of the neck portion 14 fits into the through hole 20 a of the upper plate portion 20, and the portion above the large diameter portion 14 a of the neck portion 14 is the upper plate portion 20. It projects more than it does.

In the present invention, the bending rigidity of the upper plate portion in the cap is preferably higher than the bending rigidity of the outer cylinder wall. Thereby, when pressing the opposing part in an outer cylinder wall to radial inside, an upper-plate part deform | transforms with a deformation | transformation of an outer cylinder wall, and it can suppress that an upper cover part opens unexpectedly.
The aspect which makes the bending rigidity of an upper board part higher than the bending rigidity of an outer cylinder wall is not specifically limited, The aspect which makes the thickness of an upper board part thicker than the thickness of an outer cylinder wall, the material which forms an outer cylinder wall The aspect which forms an upper board part with a material which also becomes high in bending rigidity, the aspect which provides a rib in an upper board part, and reinforces etc. are mentioned. Among them, an aspect in which the thickness of the upper plate portion is thicker than the thickness of the outer cylinder wall is preferable from the viewpoint of easy production.

The projecting cylindrical portion 22 is provided to extend upward from the inner peripheral edge of the upper plate portion 20, that is, the periphery of the through hole 20a in the upper plate portion 20. The projecting cylindrical portion 22 is cylindrical. The inner diameter of the projecting cylindrical portion 22 is substantially equal to the outer diameter of the large diameter portion 14 a of the neck portion 14 of the container main body 2, and the neck portion 14 of the container main body 2 has the large diameter portion 14 a inside the projecting cylindrical portion 22. It's supposed to fit in.

It is preferable that one or more notches extending downward from the upper end of the protruding cylindrical portion are formed in the protruding cylindrical portion in the circumferential direction. As a result, since the projecting cylindrical portion is easily bent, the neck portion of the container main body may be fitted into the projecting cylindrical portion to engage the first engaging portion with the second engaging portion described later. It will be easier. The number of notches formed in the projecting cylindrical portion is not particularly limited, and may be one or more.
In this example, a portion including the front surface portion on the opposite side to the hinge portion 24 in the projecting cylindrical portion 22 is cut away to form a cutout 22a. The notch 22a is formed on the front surface of the projecting cylindrical portion 22, thereby facilitating the operation of placing the contents poured out from the neck portion 14 on a toothbrush or the like.
The notch formed in the projecting cylindrical portion may have a slit shape.

A second engaging portion 28 is formed on a portion close to the upper end of the inner peripheral surface 22b of the projecting cylindrical portion 22. The second engaging portion 28 is formed of a ridge extending in the circumferential direction of the inner peripheral surface 22b and protruding inward in the radial direction. .
The projecting cylindrical portion 22 has flexibility, and when the neck portion 14 of the container main body 2 is fitted inside the projecting cylindrical portion 22 of the cap 3 and the cap 3 is attached to the container main body 2, the first The engagement portion 16 and the second engagement portion 28 form an engagement structure. Specifically, the second engagement portion 28 is caught and locked to the lower side of the first engagement portion 16 to form an engagement structure.

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 The cap 3 is pushed up and removed from the container main body 2 by releasing the engagement structure between the second engaging portion 28 and the second engaging portion 28.

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.

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 upper end portion of the neck portion 14 protruding from the through hole 20a of the upper plate portion 20 is fitted inside the protrusion 30, and the contents leak Is suppressed. That is, the upper cover 26 closes the upper end opening 14b of the neck 14 so as to open and close freely in a so-called outer ring system. 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.

On the opposite side of the hinge portion 24 in the upper lid portion 26, a finger hook portion 32 which protrudes outward in the radial direction is formed. As a result, the upper lid 26 can be easily opened by putting a finger on the finger hook 32.
The shape and size of the finger hook portion 32 are not particularly limited, and can be appropriately set according to the size of the cap 3 and the like.
