Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for filling and holding liquid contents such as liquid detergents and liquid cosmetics, and more particularly to an ultra-thin container suitable as a refill container. It is intended to improve the disposability of containers after use.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of saving resources and reducing the amount of waste, refill containers for refilling only contents have been used on the assumption that separately sold containers with pumps are used as they are. Is coming.

Various types of refill containers are known, such as a bag-like container, a pouch container formed by laminating a plurality of thin sheets of aluminum or the like and a bottle-type container.

[0004] Among the refillable containers described above, especially bottle-type containers have a high degree of autonomy, and when filling the contents in a continuous line, it is easy to align the individual containers along the line. Therefore, there is an advantage that the filling can be performed more efficiently and the productivity can be remarkably improved as compared with a bag-like container or a pouch container having almost no autonomy. By the way, such a container having high autonomy has a space for filling the contents inside,
Due to the bulkiness, in the distribution process from the container manufacturing stage to the stage of filling the contents into the container, efficient transportation of the container is not possible, which increases the cost, and at the time of disposal after refilling the contents. Also left the problem where the containers could not be compacted and discarded.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a new superconducting container which can be disposed of compactly after use, in addition to ensuring the independence of the container and realizing efficient transportation. The idea is to propose a thin container.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a container comprising an ultra-thin member having an opening communicating with the inside of a container body,
This container is an ultra-thin container characterized by having a bellows-like folded portion capable of holding the container itself in a flat state by pressing the container at least in one direction by pressing the folded portion. It is particularly desirable that the folds extend from the bottom of the container body to the upper part where the spout is provided. Here, the ultra-thin container according to the present invention uses a resin of 0.08 g / cc (a container having a capacity capable of filling a content of 600 cc) of about 50 g in a conventionally used thin-wall type container. (Resin of the same degree is used), and is made of an ultra-thin member whose resin usage is about 0.004 to 0.025 g / cc. As a material constituting the container, a resin such as polyethylene, polyethylene terephthalate, or polypropylene can be used.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 shows the configuration of an ultra-thin container according to the present invention. In the figure, 1 is a container body composed of an ultra-thin member made of a resin such as plastic,
Reference numeral 2 denotes a spout which is attached to the container body 1 and through which the contents are taken out of the container (used as a filling port when filling the contents into the container body). For example, a cap 2a is attached so that the contents after filling do not leak.

Reference numeral 3 denotes a plurality of folded portions formed at the same time when the container body 1 is blow-molded. The folded portion 3 causes the container body 1 to assume a bellows shape or an accordion shape.

Before the container shown in FIG. 1 is filled with the contents, the container is folded by the folded portion 3 and keeps a flat state, so that the container shown in FIG. Since the containers can be arranged and packed in such a state in an orderly manner, more containers can be transported when packed and transported in a transport container having a fixed volume.

[0010] Even if an ultra-thin container does not have the folded portion 3, more containers can be transported by crushing the container itself. In addition, it is difficult to align the contents in a filling line of the contents, and in-mold labels (in-mold labels are labels formed by a label-insert type blow molding method). In the case of the container having the mark, it is difficult to see the display of the label when the container is crushed, and the label is easily soiled because the container is crushed in a complicated manner. In the present invention, the container bodies are all aligned in the same direction, so that the alignment of the container bodies is simple. It is easy to see, and it is also possible to protect only the display label, so that it is not easily stained.

FIG. 1 shows an example in which the fold of the folded portion 3 extends from the bottom of the container main body 1 along the upper part of the spout 2 where the spout 2 is provided. By providing, even in a container using an ultra-thin member, the rigidity of the container main body can be increased, which is advantageous for enhancing the independence, and particularly when filling the contents efficiently, Can be performed. The fold of the folded portion 3 is not particularly limited to the case where the folded portion 3 is provided from the bottom to the top of the container body.
If necessary, it may be provided along the body of the container, or two or more types of folded portions having different folding directions may be provided.

When filling the container according to the present invention with contents, a predetermined amount of compressed air or the like is supplied from a spout 2 of the container body 1 to inflate the container body 1 once and fill the contents therein. .

Although the container body 1 is folded in one direction by a plurality of folded portions 3, grooves may be provided at predetermined intervals in the container body 1 and the container body 1 may be folded starting from the groove.

As the material of the container, a resin such as polyethylene, polyethylene terephthalate or polypropylene can be used, but the present invention is not limited to this, and various materials can be applied as needed. For the molding of the container, a normal molding technique such as blow molding or pressure molding is applied.

FIG. 3 shows a state in which the container shown in FIG. 1 is filled with the contents. In such a container, after the contents are filled, the folded portion 3 is extended and visually confirmed. It cannot be performed, and there is no difference in appearance from a normal container except for using an ultra-thin member.

[0016]

According to the present invention, when the contents are not filled, the containers can be compactly packed, so that the containers can be transported efficiently, and the containers can be disposed after use. There is nothing bulky.
