Abstract

PROBLEM TO BE SOLVED: To compress a container very easily and safely into a compact state after consumption of contents and solve a problem of bulk effectively in waste disposal by using a flexible material to form a peripheral wall portion of the container into a double structure and confining air or liquid in a space between the double peripheral walls. SOLUTION: A cylindrical container body 1 having a double wall structure of an inner peripheral wall 11a and an outer peripheral wall 11b is formed by using a flexible film which is unable to impart shape retention to the container body in the film itself as a whole and, by confining air 2 into a space between the inner peripheral wall 11a and the outer peripheral wall 11b, the container body 1 is held in an upstanding state. A projecting nozzle 3 made of a flexible film in a similar way is projectingly formed so that a nozzle port 31 is allowed to communicate with an opening 14 of the container body 1. Further, two recess and protrusion fitting line fasteners 4 for opening and closing a nozzle port 31 are provided in vertically parallel with each other on inner faces of the projecting nozzle 3, which are opposed to each other when the container is pressed flatly, and a pair of tabs for fitting and disengaging operation are provided on the outer side of an upper portion of the nozzle 3. In the case where the container body 1 becomes empty, the double structural portion is suitably broken to reduce the size of the container body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a packaging container, and more particularly, to water, tea, soft drink, fruit drink, soup, sauce,
The present invention relates to a packaging container for containing various liquid or paste-like substances such as soy sauce, edible oils and fats, miso and other foods, and chemical substances such as industrial oils and paints.

[0002]

2. Description of the Related Art Conventionally, various containers made of glass, metal, synthetic resin and the like have been put into practical use as containers for packaging liquid or paste-like substances. PET bottles are widely used.

[0003] However, conventional containers consume contents such as PET bottles, and when empty, the containers become bulky, resulting in poor storage efficiency and transportation efficiency, which is a major problem in garbage disposal. Conventionally, in order to make the bulk as small as possible, in a general household, it was actually crushed and garbage was discharged, but in spite of such a troublesome operation, a flat plate was used. It was extremely difficult to crush it, and there was the danger of injuries at times.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the above-mentioned problems. It is intended to provide a container.

[0005] The inventor of the present invention has conducted various studies on the container structure in order to achieve the above-mentioned object. In addition, if gas or liquid is sealed in the space formed by the double structure, sufficient shape retention as a container can be imparted. By extracting the gas or liquid enclosed in the heavy structure part, the shape retention of the container is lost, and it has been found that a very good result of being naturally reduced to a compact state is obtained, and the present invention is completed. did.

[0006]

In other words, the present invention uses a flexible material which cannot provide shape retention by itself and at least the inner peripheral wall of the container has a double inner / outer structure.
The above object has been achieved by a packaging container characterized in that a gas or a liquid is sealed between outer peripheral walls.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the portion having a double structure may be the entire container including the bottom portion, but it is necessary that at least the peripheral wall of the container has an inner / outer double structure. is there. The shape of the container itself may be any shape such as a cylindrical shape and a rectangular tube shape.

In the present invention, it is indispensable to use a flexible material which cannot provide shape retention as such a material having a double structure in order to make an empty container compact. For example, a synthetic resin film having a thickness of 50 to 200 μm such as nylon is preferred. The container material other than the double structure portion may be of any type, but it is preferable to use the same material as the double structure portion in terms of molding, downsizing, and further dust treatment.

In the present invention, as the gas or liquid sealed between the inner and outer double peripheral walls, for example, air or water is preferable because of its excellent handling and extraction and disposal properties.

In the present invention, the inner and outer double peripheral walls may be fixedly joined only by the neck of the body, and all other parts may be formed by forming a space between the inner and outer peripheral walls. In this case, it is more advantageous to further provide a joint portion in order to improve shape retention. Incidentally, in this case, if the space is completely divided by the joint portion and a plurality of compartments which do not communicate with each other are provided, even if some of the compartments are damaged and gas or liquid leaks, the overall In addition, shape retention can be maintained, and particularly good results can be obtained.

In the present invention, a protruding nozzle made of a flexible material further provided with an opening and closing fitting line fastener for opening and closing is formed on the end face of the opening of the container so as to communicate with the opening. In the case where the contents cannot be used up at one time, the remaining amount can be sealed and stored by opening and closing the concave and convex fitting line fastener, and can be reused when necessary, which is more desirable. In addition, when such a nozzle is provided, there is no problem of separation and recovery as in the case where a metal cap or the like is used, and this is advantageous in terms of waste disposal.
In addition, it is preferable that the number of the concave and convex fitting line fasteners be plural in order to more reliably maintain the sealing performance.

Further, in the case of forming the protruding nozzle as described above, furthermore, in order to more easily release the fitting state of the concave and convex fitting line fastener on the outer portion of the protruding nozzle and open the nozzle. It is preferable to provide a pair of fitting and disengaging operation knob protrusions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below with reference to the drawings showing embodiments.

FIGS. 1 and 2 show a first embodiment of the present invention, in which a container 1 is entirely cylindrically formed of a nylon film (120 μm thick) which cannot provide shape retention by itself. The peripheral wall portion 11 has an inner / outer double structure of an inner peripheral wall 11a and an outer peripheral wall 11b. Air 2 is sealed between the inner peripheral wall 11a and the outer peripheral wall 11b,
The container 1 is kept upright. 3 is a protruding nozzle,
Similarly, it is formed of a nylon film, and is formed so that the nozzle port 31 communicates with the opening 14 of the container 1 to protrude.
The protruding nozzle 3 is provided with two uneven fitting line fasteners 4 for opening and closing the nozzle port 31 on an inner surface that is in contact with the press-fitting, and is vertically parallel to each other. A knob projection 5 is provided.

FIG. 3 shows a second embodiment of the present invention, in which the peripheral wall portion 11 is formed between the inner peripheral wall 11a and the outer peripheral wall 11b.
In addition to the outer double structure, the bottom wall 12 also has an inner / outer double structure of the inner bottom wall 12a and the outer bottom wall 12b. A plurality of compartments are formed by providing joints 13 at appropriate locations, and air 2 is sealed in each compartment. Other reference numerals indicate the same members as in the first embodiment.

According to the two embodiments of the present invention, since the air is sealed in the inner / outer double structure, the container 1 is provided with a shape-retaining property, the upright state is maintained, and the normal state is maintained. The contents can be filled and stored in the same manner as a PET bottle, and when the contents are consumed and emptied, the double structure portion can be appropriately defeated to extract the enclosed air, Since the shape can no longer be maintained, the size is naturally reduced. Further, if necessary, a compact state can be easily obtained simply by pressing with a hand or the like. Further, when there is a remaining amount, it can be once sealed (FIG. 4) by appropriately using the uneven fitting line fastener 4, and can be opened and reused when necessary. At the time of this opening, the fitting state is easily released by holding the knob protrusion 5 and pulling them in opposite directions (the direction of the arrow in FIG. 4), and the nozzle port 31 is opened.

[0017]

According to the present invention, since the packaging container can be compressed into a compact state very easily and safely after the consumption of the contents, the problem of bulk in garbage disposal can be reduced. Can be eliminated.
