Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper container formed from a waste product of a paper pack by cutting off a paper pack used as a beverage container for milk, juice or the like after consumption of the beverage. An object of the present invention is to provide a frame device attached to an opening edge formed by cutting the paper container, and to make the paper container usable as a container for various small articles.

[0002]

2. Description of the Related Art In recent years, paper packs have been widely used for beverage containers such as milk and juice, and the consumption amount at home has reached an enormous amount.

Therefore, since the number of paper packs discarded after the consumption of beverages is considerable, it is desirable to effectively utilize resources and reduce waste by using these paper packs as waste products.

[0004]

The paper pack is formed in a substantially square columnar shape having a peripheral wall consisting of four side walls in the circumferential direction on the bottom wall and is made of a relatively strong paper material. In order to effectively utilize the above, it is preferable to cut the paper pack to form a paper container having an upper opening and use this as a container for various small articles.

[0005] By the way, a paper container obtained by cutting the paper pack only has a poor decorative taste, and is too unsatisfactory to put it on a desk for use. Further, although it is formed of a relatively tough paper material, it has poor shape retention, and in particular, the opening edge formed at the cut end is fragile and cannot be used as a small case.

Further, the paper container can be used as a writing tool such as a pencil, a remote control device for household electric appliances, or a stand for storing small articles such as tubes such as mayonnaise in an upright state. Can also be used as a dust box, and in that case, it is preferable to provide a lid plate whose opening can be opened and closed.
