Problems solved by technology

[0002] Most of the existing cups are made of plastic, ceramics and glass. Relatively speaking, these materials have the disadvantages of being not environmentally friendly or of high quality and not easy to carry, which cannot meet people's needs for convenience and environmental protection.
[0003] Many people also choose paper cups, thinking that they are environmentally friendly, but they find that ordinary paper cups also have many shortcomings. It is filled with hot water, it is easy to burn people
Another disadvantage of ordinary paper cups without lids is that dust and other substances are easy to fall into the cups, and people will drink them accidentally. This is an important way for diseases to enter from the mouth.
That is, some paper cups have cup lids, but no ventilation holes, making it difficult for the heat in the cup to escape.
It can be seen that most cups are difficult to be environmentally friendly and convenient at the same time to meet people's needs.

Abstract

The invention discloses an environmental-friendly convenient paper cup. The invention aims to prevent dust and other substances from dropping into the cup body so as to prevent illness from entering via the mouth. A cup cover is arranged on the cup body; a plurality of first through holes are formed in the cover surface of the cup cover, and a good breathable effect can be achieved. When the cup body is filled with hot water, a breathable effect is achieved, and the condition that the cup cover and cup body deform due to extremely high pressure inside the cup body is avoided. In order to prevent tiny matters such as dust from entering the cup body via the first through holes, a spacer is clamped in the cup cover, a plurality of second through holes formed in the spacer also can achieve the breathable effect, the first through holes and the second through holes are staggered with one another, and the aim of preventing the tiny matters such as dust from entering the cup body is achieved.

Description

technical field [0001] The invention relates to a cup, in particular to an environmentally friendly and convenient paper cup. Background technique [0002] Most of the existing cups are made of plastics, pottery and glass. Relatively speaking, these materials have the disadvantages of being not environmentally friendly or of high quality and being inconvenient to carry, which cannot meet the needs of people for convenience and environmental protection. [0003] Many people also choose paper cups, thinking that they are environmentally friendly, but they find that ordinary paper cups also have many shortcomings. It is filled with hot water, which can easily burn people. Another disadvantage of ordinary paper cups without lids is that dust and other substances are easy to fall into the cups, and people will drink them accidentally. This is an important way for diseases to enter from the mouth. That is, some paper cups have cup lids, but there are no ventilation holes, which ...
