Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container filled with, for example, dairy products.

[0002]

2. Description of the Related Art A container of this type includes a container body and a lid. The entire container body is formed of a synthetic resin, and the entire lid is formed of a laminate including aluminum foil. It has been known.

[0003]

In the above-mentioned container, since the container body and the lid are formed of different kinds of materials, it is necessary to handle the container body and the lid separately when recycling the container, which is not easy to recycle. .

A laminate including an aluminum foil has a certain degree of shape retention. For this reason, once the lid is opened, if the lid is put on the mouth, it is easy to falsify it so that it looks as if it has not been opened.

[0005] In addition, the hand or mouth may be cut off with a lid when opening, which is a problem in safety.

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid container which can be easily recycled, prevents tampering such as mischief, and has no safety problem. It is.

[0007]

A liquid container according to the present invention comprises a container body having a mouth, and a lid closing the mouth. It is formed of a synthetic resin.

In the liquid container according to the present invention, since the container body and the lid are both made of synthetic resin, it is not necessary to handle the container body and the lid separately when recycling the container. Therefore, recycling of the container is facilitated, which is advantageous for environmental protection.

Further, if the type of synthetic resin forming the container body and the lid is the same, and a straw formed of the same type of synthetic resin is provided in the liquid container, recycling is further enhanced. It will be easier.

[0010] Further, it is preferable that the lid is provided with a slipper for facilitating piercing of a straw.

When the lid is made of a synthetic resin, there is a limit in reducing the thickness of the lid due to molding. for that reason,
The synthetic resin lid has higher strength and is harder to pierce the straw into the lid than the above-mentioned laminated lid, but when the lid is slippery, the tip of the straw is hooked on the lid, making it harder to slip, The straw can be easily pierced.

[0012] Furthermore, the non-slip may be formed by a concave portion and / or a convex portion.

Embodiments of the present invention will be described below with reference to the drawings.
