Description

Paper cup {Paper cup}

The present invention relates to a paper cup, and more particularly, to a paper cup that allows for easy opening and overcoming an unsanitary problem by allowing the opening to be opened relatively easily.

It is not uncommon to find water purifiers for drinking water, and disposable paper cups are often found in restaurants, department stores, hospitals, or large buildings.

The paper cups provided in these cups are largely cup-shaped and flatly stacked to be stacked in layers. In addition to the use of many people, the paper cups need to be reduced in size and installed in a narrow place. In view of the above, the latter one (hereinafter referred to as "paper cup") is often employed.

In the case of using such a paper cup, first, one paper cup is taken out from the top or the bottom of the packaging apparatus provided with the paper cup, and then the both side regions are pressed radially inward. Then, an opening formed at one end of the paper cup is opened so that water can be edible through the opened opening.

However, the conventionally known paper cups are not only inconvenient in use but also very inconvenient to use because the openings do not easily open even when the sides of the paper cup are pressed with one hand. There is a disadvantage that it is not good for hygiene because you have to open your hands.

As a way to solve this disadvantage, the paper cup is disclosed in the application number 20-2001-0023017 to easily open the opening of the paper cup. The disclosed paper cups, in forming a plurality of fold lines on the sides of the paper cup, form a fold line in an inverted "∨" shape that gradually widens downwards from the top opening of the paper cup. Thus, when pressing the sides of the paper cup with one hand so that the opening can be easily opened due to the folding line.

As another technique for easily opening the opening of a paper cup, a disposable paper cup is also disclosed in Application No. 20-2002-0014532. The disclosed paper cups form an overlapping line extending from the top center to the bottom both sides on each of the inner surfaces of the front and rear surfaces of the paper cup, and at the same time, overlapping the inner side over the top opening. This also corresponds to a technique that allows the opening of the paper cup to be easily opened by pressing both sides of the paper cup with one hand.

In line with the point at which efforts are being made to easily open the openings of the paper cups which are commonly encountered in the surrounding area, the present applicant has adopted a method different from the disclosed technology to make it easier to open the openings of the paper cups. An effort was made.

It is an object of the present invention to provide a paper cup that can be relatively easy to open the opening to overcome the problems of convenience and unsanitary.
