Problems solved by technology

[0005] However, the strength of the existing paper lid is too weak, and the lid cannot be firmly attached to the cup, so there is a problem that the lid is easily separated from the cup, and the drink is slightly moved and leaks out, so the paper lid is used. It is not a simple matter to replace the plastic cover

Embodiment Construction

[0019] Hereinafter, the present invention will be described in detail with reference to the drawings.

[0020] A paper cover is provided, which includes a top board 1 and a side wall 2 arranged downward around the top board 1, and the side wall 2 is reinforced by a reinforcing material. The paper cover is coated on one or both sides with synthetic resin.

[0021] The side wall 2 is formed by folding down the outer peripheral portion of the top plate 1 , and the corrugation 10 is preferably formed on the side wall 2 , but other wall materials may be joined to the top plate 1 .

[0022] Further, the present invention provides a paper cover, which forms a longitudinal section of the reinforcing material into a "U"-shaped strip 3, and makes the side wall 2 inserted and combined into a groove formed in the middle of the "U"-shaped strip 3.

[0023] The present invention provides a paper cover that forms a housing 11 between the inner upper end 31 of the "U" shaped band 3 and the t...

Abstract

The present invention relates to a paper cap which comprises a top plate and a side wall that is installed downward around the edge of the top plate, wherein the side wall is reinforced with reinforcing materials. The paper cup can be tightly covered with the cap by preventing the cap from being damaged through the reinforcing materials. Therefore, the cap is not easily separated from the cup. Furthermore, the invention provides a paper cup having a housing portion formed between the top plate and the upper end of the inner side of the reinforcing material. Since the housing portion houses and holds the rim of the upper end of the cup, firm coupling between the cap and the cup is enabled. Therefore, the paper cap is not easily separated from the cup and enables the prevention of overflow of drinks in the cup even if the cup is shaken.

Description

technical field [0001] The present invention relates to a cover, in particular to a cover made of paper. Background technique [0002] Plastic cups, polystyrene foam cups, and paper cups for packaged or in-store coffee, tea, ice cream, and other beverages generally use transparent and translucent plastic covers. These plastic covers are disposable, which not only causes environmental pollution problem, and when the price of oil rises, so does its manufacturing cost. [0003] Therefore, it is required to use a paper cover that can be naturally decomposed when it is discarded, reduces environmental pollution, and can reduce the burden due to rising oil prices without using petroleum products. [0004] However, the beverage carton lid can only function as a lid when the following conditions are met. The conditions are the same as the existing plastic lids, not only hygienic but also waterproof, and flexible so that it will not break when it is opened or closed repeatedly and ...
