Description

[Detailed Description of the Invention] The present invention relates to a liquid storage container for storing liquid items such as cosmetics, shampoo, conditioner, food, and medicine.

In general, containers for storing cosmetics, shampoo, etc. are made of materials such as vinyl chloride, polyester, and polypropylene, and are made of materials such as vinyl chloride, polyester, and polypropylene, and the container body 1, which forms the penumbra of a normal container, is placed around the container body 1, as shown in Figure 1. flange 1a
A thin transparent film 2 is attached to the flange 1a to seal the liquid inside the container body 1.

However, in such liquid storage containers, the seal is quite strong to prevent liquid from leaking or being torn during distribution, and when opening the container, the film must be broken at a predetermined position with scissors or a knife. It was inconvenient because it could not be opened with bare hands.

In view of this, an object of the present invention is to provide a liquid storage container that can be easily opened without requiring tools such as scissors or a knife to open the container.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

In FIG. 2, the flange portion of the vacuum-formed container body 3 adjacent to the extraction port 4 is provided with a tongue piece 5 extending outward, and a conical protrusion 6 is provided at the tip of this tongue piece 5. It is being

The tongue piece 5 and the protrusion 6 are integrally molded at the same time when the container body 3 is molded using a mold M as shown in FIG.

A recess 4a for receiving the protrusion 6 is provided at the tip of the extraction port 4.
A circular hole 7 is formed on the flange portion 3a near the concave portion 4a, and this circular hole 7 is used to hang the container on a pin or the like when displaying the product for sale.

Further, a folding line 8 is formed on the protrusion 6 side of the circular hole 7, and when the tongue piece 5 is bent along the folding line 8, the tip of the protrusion 6 fits into the recess 4a. ing.

The liquid is injected into the storage recess 9 of the container body 3, and a thin film 10 made of polyester and aluminum foil is spread over the four storage parts 9 as shown in FIG.
0 is attached to the flange portion 3a of the container body by heating.

When opening the package, as described above, by folding the tongue piece 5 along the folding line 8 and using the protrusion 6 to tear the film 10 above the recess 4a, the extraction hole can be easily made on the film 10.

Since the extraction hole opened by the protrusion 6 has a small area, it is possible to prevent hands from getting dirty when using the container, and since the protrusion 6 is always integrated with the container body 3, other objects can be removed when opening the container. There is no need to search for opening tools, and the amount of liquid extracted can be adjusted by adjusting the size of the protrusions.

Since the present invention is constructed as described above, it has the effect that the package can be opened easily without requiring scissors, knives, etc. when opening the package.
