Description

Disposable Cup Lid

The present invention relates to a cup lid, and more particularly, to a disposable cup lid capable of opening and closing to maximize the convenience of use of the disposable cup by allowing the user to select a drinking method in drinking the beverage.

In general, hot coffee is often eaten at home or in coffee shops in paper cups and the like. At this time, a synthetic resin is assembled to cover the open upper portion of the cup so as to prevent burns caused by hot steaming of the coffee and to eat coffee little by little. Cup lids are widely used.

The conventional cup lid is formed in a shape corresponding to the outer circumference of the container so as to cover the upper portion of the cup containing the high temperature contents such as coffee, the drinking hole is formed on the upper surface to enable drinking through a small inlet .

However, such a conventional cup lid is a very simple configuration in which only a large or small hole is formed in the upper surface of the body, and the user should always drink directly with the mouth directly in the hole of the body.

Therefore, while the user attempts to drink by tilting the cup in a state in which the temperature of the drink cannot be sensed, an accident in which burns on the lips or the palate are often caused by a high temperature of the drink being rapidly discharged into the drinking hole.

Recently, a method of extending the drinking hole upwardly or forming a predetermined flow path has been proposed. However, in such a structure, the cooling performance of the beverage is very insignificant, and the flow rate is not formed as much as desired. It also increases the chances of an accident.

In view of this, many users drink beverages with the cup lid removed. This is because the lip is in contact with the outer circumference of the container and the amount of the beverage can be more easily adjusted while sensing the temperature of the beverage through the opening of the mouth.

Therefore, in the case of the conventional cup lid, it is practically difficult to drink properly with the drinking hole before the beverage is cooled to a certain extent, and thus, there is no configuration except for the purpose of not overflowing the beverage.

The present invention has been made to solve the above problems, it provides a disposable cup lid capable of opening and closing having a structure that can maximize the convenience of use of the disposable cup by allowing the user to choose a drinking method in drinking the beverage.
