Abstract

PURPOSE:To obtain a water-tight rigid container used to bottle soft drinks, beer, food, etc., in it, and can be easily crushed down into a specified shape for disposal after the content is consumed. CONSTITUTION:Bellows-like or spiral pleats 5 are formed around a barrel 3 of a container 1, so that the container 1 can be crushed when an axial force is applied on the container 1 before disposal to fold the pleats 5. However, the container 1 before opened withstands an external axial force by a content 6 filled in it and an external force in the direction perpendicular to the axis by the pleats 5, thus the container 1 is prevented from being crushed during storage and transportation. After the container 1 is opened and the content 6 is consumed, there is nothing to bear the external axial force, so that the container 1 can be crushed in the axial direction by a weak force. The pleats 5 provided around the barrel 3 enhances the rigidity in the direction perpendicular to the axis, that allows reducing the thickness of the shell of the barrel 3 by an amount equivalent to the increase in the rigidity. In addition, the container 1 is excellent in heat exchange property because the barrel 3 has a large surface area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rigid container for containing soft drinks, beer, foods, etc., and more particularly to a watertight rigid container for consuming contents and discarding them.

[0002]

2. Description of the Related Art Steel cans, aluminum cans, polyethylene bottles, cans for canning and the like have been known as watertight rigid containers of this type. After consuming the contents after opening these containers, crush those that can be easily crushed, such as aluminum cans,
Those that cannot be crushed are left as they are, and are discarded in the trash box or garbage collection site.

[0003]

However, the crushed aluminum canister has a problem in that the crushed aluminum cans cannot be stacked and housed because the shapes after crushing are different, and a sharp portion is generated during crushing, which is dangerous. is there. In addition, steel cans, polyethylene bottles, and cans that cannot be crushed occupy a large area, which is an obstacle and requires frequent transportation to the garbage collection site. .

An object of the present invention is to provide a rigid container which can be easily crushed and has a constant shape after crushing.

[0005]

The watertight rigid container of the present invention has a bellows-like or spiral shape on the body 3 of the container in the watertight rigid containers 1, 7, 9 which are discarded after the contents 6 are consumed. The pleats 5 are provided so that the containers 1, 7, 9 can be crushed by folding the pleats 5 by applying an axial force before discarding.

[0006]

The conventional rigid container for enclosing liquids and solids is designed so that the container will not be deformed or crushed by external force during storage and transportation. Such an idea is discarded after consuming the contents. The same applies to the watertight rigid container. That is, the conventional watertight rigid container that is disposed of after the content is consumed is not particularly considered in workability, storage efficiency, safety, etc. at the time of disposal. The inventor of the present application paid attention to this point, and proposed the above-described structure in consideration of disposal workability and the like while maintaining the performance required for the conventional rigid container. Such a technical idea has never been considered in the conventional rigid container.

The watertight rigid container 1, 7, 9 of the present invention is a content 6 in which an external force applied in the axial direction of the container before opening is sealed.
Since the external force applied to the container is received by the bellows-shaped or spiral folds 5, it is not crushed during storage and transportation. Further, after opening and consuming the contents 6, there is nothing to receive the axial force, so that the folds 6 can be folded with a weak force, and the container 1,
It is possible to crush 7 and 9 into a vertically compressed form. Since the crushed containers are safe without any sharp points and can be stacked, many containers can be stored in a small area. In addition, the watertight rigid container 1, 7 of the present invention,
9 has the bellows-like or spiral folds 5 provided on its body, which increases the rigidity against external force in the direction perpendicular to the axis, so that the wall thickness of the body 3 can be reduced correspondingly, and the material of the body can be reduced. It does not increase the amount used. Furthermore, since the surface area of the body is large, the heat exchange performance is good, and by implementing the present invention in a coffee can, the power consumption of a vending machine or the like can be reduced.

[0008]

1 and 2 show a first embodiment of the present invention. The rigid container of this embodiment is an aluminum can 1 containing beer, in which a cylindrical body 3 integrally provided with a bottom 2 is watertightly connected to a lid 4 having a pulling plug. The body 3 is provided with a bellows-like fold 5,
After being filled with beer 6, it is stored and transported. The stress applied in the axial direction of the can 1 during storage and transportation is received by the beer 6 sealed in a watertight manner, and the stress applied in the direction perpendicular to the axis is received by the pleats 5. After opening the beer 6 after opening, by sandwiching the can 1 with both hands in the axial direction, the folds 5 are folded and the can 1 can be easily crushed in the axial direction.
The crushed container has a shape in which a can is compressed in the axial direction, so that the container can be stacked and efficiently stored.

FIG. 3 is a perspective view showing a second embodiment of the present invention. The rigid container of this embodiment is a polyethylene bottle 7 containing a soft drink, and includes a lid part 4, a body part 3 and a bottom part 2.
Is integrally formed by blow molding. The lid 4 has an inverted funnel shape, and a plug 8 is screwed into a spout at the center to be watertight. The body of the bottle 7 is provided with an integrally formed spiral fold 5. The pleats 5 allow the bottle to be crushed in the axial direction, and the external force applied to the body portion 3 in the direction perpendicular to the axis is received. When displaying the product name or the like on the bottle, the film may be wound around the body of the bottle and the product name or the like may be printed on the surface thereof. FIG. 4 shows the third aspect of the present invention.
An example is shown, and the rigid container of this example is a steel can 9 in the shape of a short prism containing small pieces of meat for pets. The can 9 is watertightly closed by a lid 4 having a hook 10. Containers 7, 9 of the second and third embodiments
Is, if the lid 4 is removed by opening the cap or raising the hook 10 and pulling, consuming soft drinks and minced meat, and then pinching the bottle 7 and can 9 with both hands in the axial direction,
The pleats 5 are folded and can be easily crushed in the axial direction.

[0010]

As described above, since the watertight rigid container of the present invention is provided with the bellows or spiral folds on the body, a weak force is exerted in the axial direction of the container after the contents are consumed. The folds can be folded just by adding and the container to be discarded can be easily crushed. Since the container after crushing has a fixed shape, it can be piled up and stored efficiently, and no sharp tip is generated, which is safe. In addition, the watertight rigid container of the present invention has an increased surface area due to the bellows-shaped or spiral-shaped pleats provided in the body portion, has high heat exchange efficiency, and can reduce power consumption of vending machines and the like.
