a plastic cup

Abstract

The invention relates to the field of plastic cups, in particular to a plastic cup, which includes a heat insulation structure, an anti-slip strip, a sealing structure, a plastic cup body, a storage structure and a filter structure; the drive rod on the base is screwed to the plastic cup body , and then make the base interfere with the drive heat insulation ring to slide with the plastic cup body, and then make the block on the heat insulation ring drive rod correspond to the rubber ring on the end cover one by one, the rubber ring interferes with the block, and the rubber ring restricts the block position, the base drives the threaded connection between the driving rod and the plastic cup body, and then the base moves away from the plastic cup body, the driving rod touches the retaining ring, and then the retaining ring touches the heat insulation ring, so that the limit between the heat insulation ring and the plastic cup body The blocks are slidably connected, so that the pull rod pulls the block against the end cap, and the block against the rubber ring, so that the gas inside the rubber ring enters the interior of the accommodation chamber, deforming the rubber pad, and then making the end cap and the plastic cup body The internal and external air pressure is balanced to facilitate the removal of the end cover.

Description

technical field [0001] The invention relates to the field of plastic cups, in particular to a plastic cup. Background technique [0002] A water cup is usually a container for people to hold liquids. It can be used to drink tea, water, coffee, drinks, etc. The water cup is a vessel that is used to hold liquids in most cases, usually made of plastic, glass, porcelain or stainless steel. Manufacturing, the cups are mostly cylindrical, open on the top, and hollow for holding things. Because of the opening of the cup, the liquid in the cup is easily polluted by the surrounding dust, so when it is placed for a long time, it is usually covered with a cup cover. [0003] However, when traditional plastic cups are used to make tea, the tea paint on the threaded connection between the cup cover and the cup body is not easy to clean, the snap-on cup cover is easily damaged, and the bottom of the single-layer plastic cup is insulated with a rubber ring , the heat insulation performanc...

AI Technical Summary

Problems solved by technology

[0003] However, when traditional plastic cups are used to make tea, the tea paint on the threaded connection between the cup cover and the cup body is not easy to clean, the snap-on cup cover is easily damaged, and the bottom of the single-layer plastic cup is insulated with a rubber ring , the heat insulation performance is poor, and the use comfort is poor. At the same time, when the temperature in the plastic cup decreases, the air pressure inside the plastic cup decreases, which makes it inconvenient to disassemble the cup cover. Need to use a separate storage box to carry tea, which is not convenient for outdoor use
