DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for filling liquids or powders (hereinafter simply referred to as contents) such as detergents and cosmetics.
Containers to hold, especially regarding ultra-thin containers suitable as refill containers, efficiency in transporting such containers,
The aim is to improve the disposability of used containers.

[0002] 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 to be used as they are. ing.

[0003] Such refillable containers include various types such as bag-shaped containers, pouch containers formed by laminating a plurality of thin sheets of aluminum or the like, or bottle-type containers having a specific space. Has been proposed.

[0004] Among the above refill containers, in particular,
Bottle-type containers have a high degree of independence, and when filling the containers in a continuous line, it is relatively easy to align the individual containers along the line. There is an advantage that it is possible to perform more efficient filling as compared with a bag-shaped container or a pouch container which does not have any, and productivity can be remarkably improved.

[0005] By the way, since a container having a high degree of self-sustainability such as a bottle-type container has a space for filling the contents therein, it is bulky. There is a disadvantage that efficient transportation cannot be performed in the distribution process of the container, such as delivery to a customer who fills and sells the product, and the cost increases.

[0006] Further, such a container has a problem in that when the contents are refilled and discarded, the containers cannot be compactly folded and discarded.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel container which can be transported in large quantities at a time while reducing the bulk of the container and which can be disposed of in a compact state after use. There is a suggestion.

[0008]

SUMMARY OF THE INVENTION The present invention is a container made of an ultra-thin material having a spout communicating with the inside of a container body, the container having at least one inflection portion in the body. Having this inflection point as a starting point, and inverting a part of the container body inside the container, and the inverted area,
An ultra-thin container, characterized in that the container can be pushed into the remaining region of the container main body and housed therein.

The inflection portion of the container having the above structure is formed in a circumferential direction along the circumference of the container body or in a central axis direction from the spout to the bottom of the container. Desirably, the amount of the material constituting the container is preferably 0.004 to 0.025 g / ml.

As the material, a thermoplastic resin such as high-density polyethylene, polyethylene terephthalate, polyethylene naphthalate or polypropylene can be used.

The ultra-thin container to be used in the present invention refers to an amount of material used in a generally known bottle-shaped container of 0.
The amount of material (resin) used is 0.004 to 0.025 g / ml for 08 g / ml (about 50 g of resin is used in a 600 ml container).
Container.

DETAILED 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. 1 in the figure is a container body,
Reference numeral 2 denotes a spout (which is used as a filling port when filling the contents) into the container body 1, and a screw can be formed in the spout 2 to fill the contents. Later, a cap can be fitted here to seal the container. Reference numeral 3 denotes an inflection portion shown in the example formed along the circumference of the container body 1.

In the container having the above-described structure, the inflection portion 3 becomes a resistance portion when the container is pressed from below, and, for example, starting from this, the lower region is as shown in FIG. , Can be inverted inside the container, and the inverted lower region is further pushed in and stored in the upper region.

The amount of material (resin) used is 0.004 to 0.025 g /
The ultra-thin container having a volume of about ml can be crushed with a relatively small load except for the spout 2, so that the bulk of the container can be reduced, so that the transport efficiency can be improved. However, since the way in which the container is crushed does not have regularity, there is a possibility that efficient supply of the container may not be possible when the container is filled with a liquid material in a continuous line.

In the present invention, as shown in FIG. 2 above, the lower part of the container is inverted and housed in the upper part of the container with the inflection portion 3 as a starting point. Stacking is possible, and not only can the containers be efficiently transported, but also the containers can be efficiently supplied on the content filling line.

FIG. 4 shows a cross section of the container in the stacking state shown in FIG. When the inflection portion 3 is provided in the container body 1, by providing the tip of the spout 2 at a position where it abuts against the bottom of the inverted container, the lower container can support the upper container. , And stable stacking becomes possible.

FIG. 5 shows another configuration example of the ultra-thin container according to the present invention. Such a container is a via-barrel type container provided with an inflection portion 3 substantially at the center of the container body 1 in the longitudinal direction, and by inverting the lower region of the container as shown in FIG. And can be stacked in a state as shown in FIG.

The container having such a structure can be housed in the lower region by inverting the upper region of the container as shown in FIG. 8. In this case, the containers are stacked in the state shown in FIG. be able to.

In the present invention, the case where the inflection portion 3 is provided around the body of the container main body 1 and the containers are compactly stacked and stacked is shown as an example, but the inflection portion 3 is connected from the spout 2 to the bottom of the container. In this case, although not shown, although the container is not shown, the body of the container main body becomes crushed and presents a dish shape, but in that the containers can be compactly stacked in a stack, There is no difference from the container shown in FIG. 1 or the container shown in FIG.

To produce an ultra-thin container according to the invention,
A preform manufactured by injection molding can be manufactured by applying a generally known biaxial stretch blow molding method. At this time, it is important that the mold used for blow molding has a shape or a structure in which the inflection portion 3 is formed.

The container according to the present invention can be filled with contents after blowing compressed air or the like into the container body 1 through the spout 2 to expand the container into a predetermined shape.

In the present invention, the case where the thickness of the body of the container body 1 has the same thickness over the whole area has been described as an example, but as shown in FIG. The thickness of the body of the upper or lower region of the container main body can be variously changed within the above-described preferred range, and in this case, storage in the remaining region of the container main body is further simplified.

[0023]

According to the present invention, the containers can be made compact, so that more containers can be loaded in a transfer box having a fixed volume, and efficient transfer becomes possible. Further, the containers can be stacked in a regular state, so that the containers can be smoothly supplied on the content filling line. Further, since the used container can be made small, it is excellent in the disposal property.
