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 liquids and powders (hereinafter simply referred to as contents) such as detergents and cosmetics, and more particularly to a container for filling contents for refilling. An object of the present invention is to improve the efficiency of transporting such a container, improve the work efficiency of filling contents into the container, and improve the disposability of the container after use.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of resource saving and reduction of the amount of waste, a large number of containers for refilling only contents have been used on the assumption that a separately sold container with a pump is used as it is. It is becoming.

Such refillable containers include bag-shaped containers, pouch containers formed by laminating a plurality of thin sheets of aluminum or the like, and bottle-type containers having a specific space shape. Containers have been proposed.

[0004] Among the above refill containers, in particular,
Bottle-type containers have a high degree of independence, so when filling the containers in a continuous line, the individual containers are relatively aligned along the line. There is an advantage that it is possible to perform more efficient filling as compared with a bag-like container or a pouch container which has almost no, and productivity can be remarkably improved.

In such a highly self-supporting container, the filling space for filling the content is fixed, so that the container is bulky and the content is filled into the container from the manufacturing stage of the container. In the distribution process up to the stage, it is not possible to efficiently transport the container, which increases the cost and leaves a problem in that the container cannot be disposed of in a compact container even when the contents are refilled and disposed of. I was

[0006] This problem can be dealt with by reducing the thickness of the container itself, but since the shape retention and self-sustainability of the container become extremely low, the container body is particularly gripped and the spout is spouted. When opening / closing, there is a possibility that the contents may leak, and improvement has been required.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to efficiently transport a container, to simplify the work efficiency at the time of filling the contents, to improve the disposability after use of the container, and to improve the disposability of the container. The present invention proposes a novel container which can prevent inadvertent leakage of contents when opening and closing the spout.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a container made of an ultra-thin material, which has a spout communicating with the inside of the container body and enables the filling space itself of the container body to be reduced before filling the contents. Wherein the container has a skirt-shaped cover that fits around the base of the spout and surrounds the container body in the vicinity of the shoulder, the cover being smaller than the outer diameter of the base of the spout. Has an opening for fitting that becomes the inner diameter,
An ultra-thin container comprising a plurality of cutout tongues formed by cutouts around the opening.

The cover can accommodate the container main body by reducing the filling space of the container main body, and has a plurality of cutouts formed by cutting the cover at the lower end thereof at intervals along the circumferential direction. It is preferable that the cut-out tongue has a tongue-like piece, and the cut-out tongue has a stopper function for holding the housing posture of the container body housed in the cover.

[0010] The amount of ultra-thin material used is 0.004-0.025g / ml
It is preferable to use, for example, a thermoplastic resin such as high-density polyethylene, polyethylene terephthalate, polyethylene naphthalate, or polypropylene. It should be noted that the material applicable to the present invention is not limited to the above materials as long as it is a thermoplastic material suitable for blow molding.

The ultra-thin container to be used in the present invention specifically refers to an amount of 0.08 g / ml of a material (resin) generally used for shaping a bottle-type container (a volume of about 600 ml). About 50g of resin)
It is about 0.04 to 0.025 g / ml.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 shows a structure of an ultra-thin container according to the present invention. In the figure, reference numeral 1 denotes an ultra-thin material having a space for filling the contents and enabling the space itself to be reduced. 2 is a spout that communicates with the inside of the container main body 1, and 3 is a skirt-shaped cover having an opening d for fitting that has an inner diameter smaller than the outer diameter D of the base of the spout 2. The cover 3 is fitted to the base of the spout 2 so as to surround the container body 1 in the region near the shoulder, and a plurality of cutout tongues formed by the cutouts 3a around the opening d. 3b.

Reference numeral 4 denotes a lower end of the cover 3.
Are cut out, and the cut-out tongues 4 are bent inward from the cover 3 starting from the bending line 4a, and the container body 1 accommodated in the cover 3 is formed.
It has a stopper function to keep the storage posture of

In the container configured as described above,
When the container is opened and the liquid material is taken out, by holding the cover 3 as shown in FIG. 2, no extra force is applied to the container body 1, so that the contents may not be inadvertently leaked. Absent.

In the transportation before filling the contents into the container, as shown in FIG. 3, the container body 1 is crushed to reduce the filling space and can be compacted by being housed in the cover 3, so that the container can be made compact. More containers can be packed in the transport box.

When the cutout tongue 4 of the cover 3 is bent inward in a state where the container is compactly packed, the cutout tongue 4 functions as a stopper.
Can be easily exposed from the cover 3 and the container body 1 can be prevented from being damaged during the transportation process.

FIG. 4 shows the appearance of the container body 1 housed in the cover 3, and FIG. 5 shows the appearance of the cover 3 alone.

To fill the container body 1 with contents, compressed air or the like is blown into the container body 1 through the spout 2 to inflate the container body 1 as shown in FIG. Fill.

The cutout tongue piece 4 having a stopper function provided on the cover 3 is preferably one that can easily return to its original position when compressed air is blown.
As shown in FIG. 6, such a container can be filled with contents only by blowing compressed air or the like into the container body, so that the filling operation can be performed easily. As shown in FIG. 3, the used container can be made compact by reducing the filling space of the container main body 1 and storing it in the cover 3, so that it is not bulky at the time of disposal.

The container body 1 can be manufactured from a preform formed by injection molding or the like, for example, according to a biaxial stretch blow molding method.

As for the cover 3, a resin sheet having a thickness that can maintain a certain degree of shape retention can be manufactured by air pressure molding or the like. When the cover 3 is formed, the opening d that fits into the base of the spout 2
Needs to be smaller than the outer diameter D of the base of the spout 2, so that the cover 3 can be securely held on the container body 1.

In the present invention, the cut-out tongue piece 3a formed by notch is provided around the opening d, so that even if the diameter of the opening d is smaller than the outer diameter of the spout 2, it is relatively easily fitted. Can be combined.

In order to attach the cover 3 to the container body 1, the container body 1 is crushed in the radial direction, and is opened d.
It should just be attached through.

Since the cover 3 can be manufactured using a sheet-like material, by performing printing or the like (decoration) in advance in a sheet state, it can be provided with a function as a display label of a product. The production of a container rich in water becomes possible.

[0025]

According to the present invention, before the contents are filled, the containers can be compactly packed, so that the efficiency of transporting the containers can be improved, and the contents can be filled. Since they can be efficiently arranged in a line, the filling operation can be simplified. Furthermore, by holding the cover, no extra force is applied to the container body, so that there is no inadvertent leakage when taking out the contents from the container, and since the container can be made small after use, the disposability is extremely excellent.
