Plastic cup

Abstract

The invention relates to the field of plastic cups, in particular to a plastic cup. The plastic cup includes a heat insulation structure, antiskid strips, a sealing structure, a plastic cup body, a storage structure and a filtering structure; a driving rod on a base is connected with the plastic cup body in a threaded mode, the base abuts against and drives a heat insulation ring and the plastic cup body to slide, the heat insulation ring drives clamping blocks on a pull rod to correspond to rubber rings on an end cover one to one, the rubber rings abut against the clamping blocks, the rubber rings limit the clamping blocks, the base drives the driving rod and is connected with the plastic cup body in a threaded mode, the base moves away from the plastic cup body, the driving rod abuts against a blocking ring, the blocking ring abuts against the heat insulation ring, the heat insulation ring is slidably connected with a limiting block on the plastic cup body, the pull rod pulls the clamping blocks to abut against the end cover, the clamping blocks abut against the rubber rings, gas inside the rubber rings enters the interior of an accommodation chamber to deform a rubber pad, air pressure inside and outside the end cover and the plastic cup body is balanced, and the end cover is convenient to disassemble.

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
