DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage container for enclosing a beverage therein.

[0002]

2. Description of the Related Art As a conventional beverage container, a resin beverage container and a metal beverage container made of steel or aluminum are known. As a resin beverage container, for example, like a plastic bottle, a resin container main body having an opening, and a screw-type cap that is removably screwed into the opening of the container main body and closes the cap, and Are known. On the other hand, as a metal beverage container, an opening end of a metal container body having a cylindrical shape or a bottomed cylindrical shape is closed with a metal lid, and an opening score is engraved on the lid. It is also known that by operating a pull tab similarly provided on the lid, a portion surrounded by the score is pressed to break this score to form an opening in the lid of the beverage container. I have.

[0003]

By the way, a beverage container made of resin can temporarily store a beverage by opening and closing the opening (spout) again with a cap after opening. There are advantages such as easy opening. However, since it is difficult to control the quality of the beverage in the beverage container, there is a disadvantage that the beverage to be put in is limited. This is because the beverage container is made of resin, so it is vulnerable to heat, the beverage in the beverage container cannot be sterilized by high-temperature sterilization, and the beverage container passes light, so the beverage in the beverage container is not It may be deteriorated by light, especially sunlight, and since the opening of the beverage container is closed with a screw-in cap, the airtightness inside the beverage container is poor and unopened. However, this is because the outside air may enter the beverage container and deteriorate the beverage inside. In addition, there is also a disadvantage that, since a beverage environment made of resin is not provided with a recycle environment, that is, an environment for reuse, the problem of waste disposal occurs when used in large quantities.

[0004] In addition, the metal beverage container has the advantage that the quality of the beverage in the beverage container can be easily controlled and the selection of the beverage to be put in is wide. This is because the beverage container is made of metal and has heat resistance, so that the beverage in the beverage container can be sterilized at high temperature, and because the beverage container does not transmit light, the beverage is deteriorated by receiving light from the outside. This is because there is little danger that the beverage container is highly airtight, so that there is little danger that outside air will enter the beverage container and deteriorate the beverage inside. In addition, since a metal beverage container is provided with a recycling environment, there is an advantage that a problem of waste disposal hardly occurs even when used in large quantities.
However, since the opening of the metal beverage container is performed by directly opening the opening in the lid, once opened, the opening cannot be closed again, and the beverage spills from the opening, or from the opening. There is a risk that dust and the like may enter the beverage container and become unsanitary, so that once opened, there is a problem in that temporarily storing the beverage in the container is problematic.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables re-closure of an opening, facilitates opening and closing of an opening, and facilitates quality control of a beverage in a beverage container. It is an object of the present invention to provide a beverage container capable of performing the following.

Further, even after the container lid is opened, the opening of the container lid is liquid-tightly closed by fitting the cap to the container lid.

According to a second aspect of the present invention, in the beverage container according to the first aspect, the container lid is formed in a substantially flat plate shape having a contour having rotational symmetry, and the container lid is formed. A score forming a closed curve concentric and similar to the contour shape of the part is engraved, and the cap has a part on the surface opposite to the side fitted to the container lid, and a part of the container lid. A projection protruding with an outline having substantially the same shape as a part of a closed curve formed by a score, and a projection formed around the projection so as to protrude around the projection, and defining a contour portion of the container lid between the projection. There is provided a guide for guiding and positioning the score of the container lid and a part of the contour of the projection so as to face each other, and the projection is substantially the same as a part of a closed curve of the score. The slope where the contour formed in the shape is convex toward the protruding direction Characterized in that it has.

[0009] In the beverage container configured as described above, the container lid is formed into a substantially flat plate shape having a rotationally symmetrical contour (for example, circular or square), and the score engraved on the container lid is the container. It is formed in a closed curve concentric and similar to the contour shape of the lid, and the cap is formed in a protruding state around the projection on the surface on the side where the projection is formed, and There is provided a guide for guiding the contour of the container lid between them, and a guide for positioning them so that the score of the container lid and a part of the contour of the projection face each other. When the contour shape is a square, these are positioned by matching any one of the corners of the contour of the container lid with the corner of the contour of the guide provided on the cap. In particular, when the contour of the container lid is circular, the positioning of the container lid is performed simply by inserting the contour of the container lid into a guide provided on the cap. In addition, since the contour portion formed to have substantially the same shape as a part of the closed curve of the score of the protrusion has a slope that becomes convex toward the protruding direction, the protrusion is pressed against the score to calculate the score. When breaking, the area where the protrusion contacts the score is reduced, and the pressing force is concentrated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a beverage container according to the present invention will be described below with reference to FIG. The beverage container 1 is a metal can body 2 (container body) formed in a substantially bottomed cylindrical shape.
Is formed in a substantially circular flat plate shape, the edge of which is
A metal container lid 3 which is fixedly fitted to the opening end of the container and closes the container in a liquid-tight manner; And a cap 4 which is closed in a liquid-tight manner.

A closed curve concentric with and similar to the contour of the container lid 3, ie, a score 5 for an opening having a concentric shape with the contour of the container lid 3, is engraved on the container lid 3. Score 5 indicates that the container lid 3 has strength enough to withstand the impact and pressure applied during transport and storage of the beverage container 1,
A cut line that reduces the strength of the container lid 3 along the curved shape, and is broken by being pressed by a projection 7 (described later) of the cap 4 to form an opening 6 in the container lid 3. Is what you do.

The cap 4 is provided on one side with a fitting groove 4a which is formed in the same shape as the edge of the container lid 3 and is fitted in a liquid-tight manner therewith. A projection 7 projecting from the surface to break the score 5 to open the container lid 3, and a projection 7 formed around the projection 7 so that the container lid 3 A substantially cylindrical guide 8 for guiding the contour portion and positioning it is provided. The protruding portion 7 is partially protruded with a contour having substantially the same shape as a part of the closed curve formed by the score 5 of the container lid 3, that is, an arc-shaped contour, and has substantially the same shape as a part of the closed curve having the score 5. The contour portion formed into a shape has a slope that becomes convex in the protruding direction, and in the present embodiment, it is assumed that the protruding portion 7 is a solid member. Here, the inclination of the protrusion 7 is referred to as an inclined portion C, and is indicated by a broken line in FIG. The guide 8 guides the edge of the container lid 3 to form one of the score 5 engraved on the container lid 3 and one of the closed curves formed by the score 5 among the contours of the protrusion 7 provided on the cap 4. The positioning is performed so that the portion and the contour portion formed in substantially the same shape face each other.

Hereinafter, a method of using the beverage container 1 configured as described above will be described. Here, in the initial state, it is assumed that the beverage container 1 is in a state where the cap 4 is fitted to the container lid 3 by the fitting groove 4a.

The opening operation of the beverage container 1 will be described below. First, the cap 4 is removed from the container lid 3, and the surface on which the protrusion 7 and the guide 8 are formed faces the container lid 3. Next, the cap 4 is pressed against the container lid 3 while guiding the edge of the container lid 3 by the guide 8 (FIG. 2).
(See (a)). At this time, the container lid 3 is guided by the guide 8 into the score 5 provided on the container lid 3 and the cap 4.
Is positioned so that a part of the closed curve of the score 5 and a contour part formed in substantially the same shape of the protruding part 7 provided in the projection 5 face each other. That is, since the contour shape of the container lid 3 and the shape of the closed curve formed by the score 5 are both concentric circles, that is, a contour shape having rotational symmetry, the projection 7 of the cap 4 is In any position in the direction, the contour of the projection 7 is guided so as to face the score 5 of the container lid 3.

In this manner, the cap 5 is positioned in such a manner that the score 5 of the container lid 3 and a part of the contour of the projection 7 of the cap 4 (the portion where the inclined portion C is formed) face each other. When the cover 4 is pressed against the container lid 3, a part of the score 5 is pressed by the contour of the protrusion 7 of the cap 4 and is broken. Here, since the projection 7 of the cap 4 has the inclined portion C in the contour part having substantially the same shape as a part of the closed curve of the score 5, a part of the score 5 is pressed by the projection 7 by this. When it breaks, the protrusion 7 and the score 5
The contact area becomes smaller, the pressing force concentrates on this contact portion, and the score 5 is broken by a small pressing force. And
When the score 5 is partially broken, the container lid 3 is opened, and an opening 6 is formed in the container lid 3 (see FIG. 3).

Next, the closing operation of the beverage container 1 will be described. Turn the cap 4 with the fitting groove 4a facing the container lid 3,

In the above embodiment, the container lid 3
Is shown as an example of a member having a flat plate shape. However, the present invention is not limited to this. For example, as shown in FIG. Such a container lid 10 may be used. Container lid 1
Reference numeral 0 denotes an edge portion fitted to the can body 2 (container main body), and a central portion thereof protrudes toward a side opposite to a side fitted to the can body 2; At its tip, a narrow-diameter projection 11 on which a plane portion 11a having a rotationally symmetrical contour is formed is provided. The plane portion 11a is provided with a score 12 that forms a closed curve concentric with and similar to the contour shape. When the container lid 10 configured as described above is used, the cap 4
Is fitted into the flat portion 11a, and the fitting groove 4a, the protrusion 7, and the guide 8 are also formed to have a size corresponding to the size of the flat portion 11a and the score 12. The opening and closing operations are performed by breaking the score 12 by the projection 7 of the cap 4 to form the opening 13 (see FIG. 5), as in the case of the container lid 3.
The closure of 3 is performed by closing the flat portion 11a with the cap 4 by fitting the fitting groove 4a of the cap 4 to the edge of the flat portion 11a as in the case of the container lid 3. .

In the above embodiment, the contour of the container lid 3 is circular. However, the shape is not limited to this. For example, the shape is limited as long as it has a rotational symmetry, such as a square. It does not do. Also, cap 4
The projection 7 has a solid hoof shape, but the shape is not limited to this, and a part of the projection 7 has substantially the same shape as a part of a closed curve formed by the score 5 of the container lid 3, that is, an arc shape. It is only necessary that the contour part projected in the contour of and having the same shape as a part of the closed curve of the score 5 has an inclined part C that is convex in the protruding direction. For example, as shown in FIG. 6, a contour portion projected with an arc-diameter-shaped contour and formed in substantially the same shape as a part of the closed curve of the score 5 has an inclined portion C protruding in the protruding direction. The projection 14 may have a curved plate shape.
