Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a hermetically sealed container in which a beverage such as juice can be contained.

Prior Art and Its Problems Cans and paper containers are known as containers used for the above-mentioned purposes. Since cans cannot be incinerated, they are difficult to dispose of after use, resulting in so-called can pollution. In addition, cans are sterilized by retort after the contents are sealed.
There is a problem that the flavor of the contents is impaired. Although these problems can be solved by paper containers, paper containers have the following problems. Because containers are made by folding a single container material,
The folded portion appears on the outer surface of the container, and the presence of the folded portion prevents the container from looking flat.

An object of the present invention is to provide a sealed beverage container that solves the problems of conventional cans and paper containers.

Means for Solving the Problems The sealed beverage container according to the present invention has two ears connected to two mutually parallel ridges formed by the top wall and body wall of the rectangular parallelepiped container body made of paper-based laminate. The top end of the container body is removed and formed into a substantially trapezoidal shape, and is superimposed on the body wall and fixed thereto, and a cap-shaped reinforcing cover made of thermoplastic synthetic resin covers the two ears with its peripheral wall at the upper end of the container body. It is placed over the body and fixed there.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

The sealed beverage container consists of a rectangular parallelepiped container body 11 that is longer in the left and right directions than the front and rear in plan view, and upper and lower cap-shaped reinforcing covers 12 and 13 that cover the upper and lower ends of the container body, respectively.

The container body 11 is of a well-known form except for two features described below, and the description thereof will be kept brief. and two upper ears 17 that are connected to two ridges in the front and back direction formed by the body wall 15 and overlapped on the body wall 15 and fused thereto, and the front and rear edges formed by the body wall 15 and the bottom wall 16. It consists of two lower ears 18 which are respectively connected to two edges in the direction and overlapped on the bottom wall 16 and fused thereto. Further, as shown in FIG. 6, the container body 11 is constituted of an outer thermoplastic synthetic resin layer 21, a paper layer 22, an aluminum foil layer 23, and an inner thermoplastic synthetic resin layer 24 in order from the outside.

Next, two feature points will be explained. The first feature is that the shape of the upper ear 17 is different from the conventional one. As shown in FIG. 5, the upper ear 17 consists of a front side component 31 that is connected to both left and right edges of the top wall 14, and a back side component 32 that is connected to the upper edge of the trunk wall 15. ，
As shown by the chain lines in the figure, the numerals 32 were initially triangular and simply overlapped with each other, but they were fused together and the tips were removed to form a trapezoidal shape.

A second feature is that the top wall 14 of the container body 11 is provided with a thin-walled portion 33 for forming a drinking spout. As shown in FIG. 6, a portion of the outer thermoplastic synthetic resin layer 21 and the paper layer 22 of the top wall 14 are removed, and the remaining portion forms a thin wall portion 33 for forming a drinking spout.
This is an elliptical shape extending outward from approximately the center of the top wall 14 toward one corner when viewed from above.

The upper reinforcing cover 12 is made of thermoplastic synthetic resin and is generally cap-shaped, and includes a peripheral wall 41 and a top wall 42 . An inward protrusion 43 is provided at the lower end of the peripheral wall 41 and is fused to the trunk wall 15 of the container body 11. Top wall 42
An annular embankment portion 44 is provided on the periphery of the upper surface.
The top wall 41 is provided with a connecting part 45 having a substantially same shape as the spout forming thin part 33 of the container body 11 and projecting downward by being made thicker than other parts. and its lower surface is fused to the upper surface of the thin wall portion 33. An annular thin-walled portion 46 for forming a drinking spout is formed at the boundary between the connecting portion 45 and other portions by forming a V-groove 47 on the lower surface of the top wall 42, and a circular knob 48 is integrally formed inside thereof. It is provided. The base of the knob 48 is adjacent to the central end of the annular thin wall portion 46 and extends on the upper surface of the top wall 42 inside thereof. A substantially square aluminum foil 49 is fused to the lower surface of the periphery of the annular thin wall portion 46 of the top wall 42, and the lower surface of the aluminum foil 49 is fused to the upper surface of the periphery of the thin wall portion 33 of the top wall 14 of the container body 11.

Note that the lower reinforcing cover 13 is different from the upper reinforcing cover 12.
Twisted connecting portion 45, annular thin wall portion 46 and knob 4
8 is removed, and its explanation will be omitted.

When opening the container, by pulling the knob 48 diagonally upward toward the outside of the container, the annular thin-walled portion 46 will break from the inner end to the outer end, and at the same time, the connecting portion will break. 45, the thin wall portion 33 of the container body 11 is pulled upward by the thin wall portion 3
A break also occurs at the periphery of the container 3, and the portion inside the annular thin wall portion 46 of the reinforcing cover 12 and the thin wall portion 33 of the container body 11 are removed, thereby forming a drinking spout there.

Even if the contents spill from the drinking spout during drinking, the spilled contents will not spill from the reinforcing cover 12 due to the presence of the embankment 44.

Effects of the Invention In the sealed beverage container according to the present invention, the cap-shaped reinforcing cover is placed over and fixed to the upper end of the container body so as to cover the two ears with its peripheral wall. In order for the wall to be covered with a reinforcing cover with two ears,
The container looks dry.

Further, since the two ears are formed into a substantially trapezoidal shape by removing the tips of each ear, the height of the peripheral wall of the cover covering the ears can be shortened, and the material of the cover can be saved.
