 The present invention relates to a liquid paper container used for milk, fruit juice beverages, sake, etc., which makes it easy to dispose of an empty container after use.

[0002]

[Prior Art]

 Recently, liquid paper containers have been replaced by conventional glass containers and metal containers, and chilled distribution type liquid foods such as milk, lactic acid bacteria drinks, liquid soups, and long-term storage of sake, fruit juice drinks, and noodle soups are required. It has come to be used in large quantities in a wide range of applications such as room temperature liquid foods. And, these liquid paper containers that are used in large quantities can be thrown away in bulky form together with general trash from households after use of the products inside, or housewives can work hard on the torso and bottom. It was just crushed and thrown away.

[0003]

[Problems to be solved by the device]

 However, due to the recent problems of environmental destruction, improvement of industrial waste treatment methods is required, and packaging materials are also required to be easy to dispose of empty containers after the contents are used. I came. Liquid paper containers used for chilled distribution type liquid foods such as milk use a relatively simple laminated material of polyethylene / paper / polyethylene composition and can be crushed by some means, but they are usually crushed. Liquid paper containers used for warm-flowing type liquid foods are particularly rigid because of the relatively multi-layered laminated materials such as polyethylene / paper / aluminium foil / polyethylene terephthalate / polyethylene construction. In the case of housewives, they could only be crushed to a certain extent and were discarded in bulk. The present invention is a liquid paper container designed so that an empty liquid paper container after use can be discarded without making it as bulky as possible.

Means for Solving the Problems The present invention relates to a rectangular liquid paper container having a gable type or a flat top, as shown in FIG. A liquid paper container that has a tongue piece (50) that is not bonded to other components on the edge of the bottom plate (14) that is located, and that can be disposed of without emptying the empty container after using it. is there.

The bottom part of the paper container of the present invention is for closing the bottom part of the container. As shown in FIG. 1, two left and right folded bottom plates (11, 13) and a bottom bottom plate. (11), a front bottom plate (14) having a tongue (50), and two sealing pieces (12, 15).

The tongue piece (50) which is not adhered to the other constituent pieces of the present invention is such that all the folded and overlapped parts are firmly adhered to each other in the constituent piece at the bottom of the ordinary paper container. This means that the back surface of this tongue is in contact with the bottom plate (12) on the back surface but is not bonded.

The tongue of the present invention may be provided at any position on the edge of the front bottom plate (14).
