Abstract

(57) [Summary] [PROBLEMS] To enable the body of a can to be expanded and contracted. It can be easily expanded and contracted without much force. SOLUTION: A body 2 of a can 1 is formed in a bellows shape so as to be able to expand and contract.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to cans filled with soft drinks and other various products.

[0002]

[Prior art]

 Since the cans used for soft drinks are bulky, even if they are not heavy, the cost of transporting them from the can manufacturing plant to the filling factory is high, which accounts for the majority of the price of soft drinks. Also, it requires a large space for storage because it is bulky.

[0003] Furthermore, empty cans after drinking the contents are often discarded as they are because it is troublesome to crush them. For this reason, it is bulky and the recovery amount increases.

[0004] Furthermore, even if an attempt is made to crush the can in order to reduce the recovery amount, the tin can cannot be crushed by hand or foot because it is hard. Aluminum cans are easier to crush than tin cans, but still require considerable force. Even if the foot is actually crushed by the foot, it must be trampled many times with considerable force, and considerable effort is required.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and is capable of expanding and contracting the body of a can without any need for a great deal of force. As a result, transportation costs and storage space can be reduced, and empty cans can be easily crushed when the contents have been drunk. The purpose of the present invention is to provide a can that can be collected in a state where it can be collected, and can be easily performed by gently stepping on once when crushing.

[0006]

[Means for Solving the Problems]

 The gist of the present invention resides in a can characterized in that the body of the can is formed in a bellows shape so as to be able to expand and contract.

Further, in the above configuration, the bent portion of the bellows may be made thinner or bulged in a semicircular shape. This makes it easier to expand and contract the bellows.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view of the present invention, FIG. 2 is a front view of the same, FIG. 3 is an enlarged sectional view of a portion A in FIG. 2, and FIG. 4 is a front view in a contracted state.

In the figure, reference numeral 1 denotes a soft drink can, which has a body 2 formed in a bellows shape so as to be extendable and contractible. Reference numeral 3 denotes an upper lid, and 4 denotes a bottom lid.

The can 1 is manufactured with the body 2 extended as shown in FIGS. 1 and 2. When transported from a can manufacturing plant to a soft drink filling plant, they are shrunk and transported, and then stretched again during filling. This is done using a machine to improve efficiency. Furthermore, when the purchaser throws away the empty cans after drinking, they shrink and crush them again.

Further, when the empty can is shrunk and crushed when discarded, the can 1 can be easily crushed with one step by standing up and lightly stepping on the foot.

As shown in FIG. 5, the bent portion 2a of the bellows may be made thinner so that the bellows-shaped body portion 2 of the can 1 can be more easily expanded and contracted.

For the same purpose, the bent portion 2 a of the bellows may be expanded in a semicircular shape as shown in FIG. In this way, the strength against impact from the side surface of the body 2 can be increased.

[0014]

[Effect of the invention]

 The present invention has the above-described structure and operation, and can extend and contract the body of the can, and can easily expand and contract without much force. Therefore, by reducing the size, transportation costs and storage space can be reduced. In addition, when empty cans after drinking the contents can be easily crushed, it is not troublesome to crush. Therefore, the probability of collection in the state where the cans are crushed is higher than before, and the collection amount can be increased. Furthermore, when crushing at the time of collection, it can be easily performed by gently stepping on once, and the efficiency of the collection operation can be improved.
