Abstract

A can for a beverage such as a cooling beverage which can be reduced in volume after the beverage has been drunk. An arbitrary number of between 3 to 10 spiral grooves (3) of a recessed or raised shape in section are formed at equal intervals at an oblique angle of approx. 60<o> around the outer cylindrical periphery (2) of a can (1) for a beverage such as a cooling beverage, beer, fruit juice, etc. The spiral grooves are formed alternately with recessed and raised sections according to the thickness and length of the can, or are formed with recessed or raised sections linked as broken lines (4) along the optimum grooves for the length and the thickness of the can. After the beverage is drunk, the top and bottom of the can are gripped by the hands, and the can is then twisted about its outer periphery in the oblique direction of the grooves to reduce its height so that it is collapsed between the top and bottom of the can. Since the volume of the can is reduced, the storage, recovery and re-cycling of the can can be readily performed for larger quantities of cans than is possible with conventional ones.

Description

Details

Title of the Invention Beverage can Technical field

Invention of beverage cans, mainly containers for soft drinks, etc.

Background art

Conventionally, bottles and cans have been used as containers for soft drinks, coffee and beer. Bottled containers are renewable, but heavy and fragile, making them unsuitable for excursions. Bottled containers are light in weight and easy to warm and cool, so it is convenient to take with you for excursions. However, empty cans after drinking water were often thrown away.

For this reason, it has become a major social issue in terms of public morals, and in some areas, resources are being shouted and the collection of empty cans has been legislated.

As a countermeasure, reducing the volume of the can after drinking is also a major solution, and the present invention is to reduce the volume of the can without using tools. . Disclosure of the invention

Conical or convex cross section (3) on the cylindrical outer periphery (2) of beverage cans (1) for soft drinks, beer, juice, etc. (60) Arbitrary numbers of 3 to 10 rods were formed at equal intervals with front and rear inclination angles. The spiral groove is alternately provided with a GD-shaped cross section and a convex cross section depending on the thickness and length of the can, or a continuous concave or convex cross section with a broken line (4). Then, form a groove that is optimal for the length and thickness of the can.

Rather than reinforcing the can, the spiral groove is used when the smooth plate surface (5) between the grooves is compressed when the can is twisted to make it smaller after drinking. The guideline was designed to be able to move in the same direction as the inclination of the spiral strip. BRIEF DESCRIPTION OF THE FIGURES

Best mode for carrying out the explanation

The cross-sectional shape of the spiral groove (5) is concave, convex, approximately V-shaped, approximately U-shaped, square-shaped, etc., only concave, only convex, or a combination of concave and convex. Set the angle of inclination of the spiral groove, the number of shapes, etc. according to the material, thickness and length of the can.

Also, if these spiral grooves are formed by continuous ゃ -shaped and convex shapes in a broken line shape, the spiral grooves become a guide line in which the can collapses when the can is twisted. In the early and late stages when the can collapses, the spiral groove is deformed and a certain degree of permeability is required. Especially in the latter stage of crushing, the spiral groove near the upper and lower surfaces (6) of the can becomes hard and difficult to peel, but in the case of a broken line, the twisting direction changes slightly, and the role of Guy Drain It is easy to twist to the end while performing well, and has low resistance.

When the inclination angle of the spiral groove is large, the twisting distance is large and the amount of vertical movement is large, but a large amount of force is required.

Conversely, if the inclination angle is steep, the initial force of twisting is required, and the collapsed state does not shrink much in the vertical direction, and the middle part of the can can be mimicked.

Conventionally, a viper helical tube has been used for piping for air conditioning of buildings, etc. However, since this spiral strip continuously extends around the 暂 'and the inclination angle is extremely loose, it is convenient to bend the pipe angle by hand, but it is impossible to twist it. It is.

The spiral groove of the present invention has an inclination angle of about 60 degrees, but this setting differs depending on the length of the can and the size of the diameter. The slope is slightly loosened and twisted many times to shrink it.If the pipe is thick and short, the slope is slightly increased and twisted slightly to make it shrink. Arbitrary numbers of about 10 were formed at regular intervals according to the conditions such as the thickness and length of the can. Industrial use and usage

A thin plate of material at the outer periphery of the can is formed into a cylindrical shape after forming a concave or convex spiral groove by pressing or rolling, or integrated into a cylindrical shape using a continuous mold Concave and convex spiral strips are simultaneously formed on the outer periphery of the pressed product.

After injecting drinking water, the top of the can is covered and shipped as a finished product.

After the consumer purchases and drinks the canned drinking water, the upper part of the can is grasped with one hand and the lower part of the can is grasped with the other hand, and the can is twisted in the direction of the spiral of the can. The outer surface is twisted and the height shrinks to form a drum shape, and when further twisted, the can shrinks as if it were compressed from above and below, and the volume is 30% of the conventional state. Because of the following, it is possible to store and dispose of this in a larger amount than in the past when taking it home or throwing it into a wastebasket or collecting it.

As a result, the drinker shrinks the container, which lowers the cost of recovering the rent and greatly contributes to the industry.

Claims

Bill of claim

A cylindrical or convex spiral groove (3) with a concave or convex cross section is inclined at about 60 degrees on the cylindrical outer peripheral part (2) of beverage cans (1) for soft drinks, beer, juice, etc. Arbitrary numbers of 3 to 10 were formed at equal intervals with corners.

The spiral strip has a concave and a convex cross-section alternately depending on the thickness and length of the can, or has a cross-section 00 or a convex cross-section (4). Then, form a groove that is optimal for the length and thickness of the can.
