Anti-scalding plastic cup

Abstract

The invention discloses an anti-scald plastic water cup, comprising: a basic plastic cup body and a protective cover, the protective cover is arranged outside the basic plastic cup body, the protective cover is concentric with the basic plastic cup body, the basic The outer wall of the plastic cup is provided with a limit groove, the bottom of the protective cover is provided with a limit ring corresponding to the limit groove, and several annular closed holes are arranged in the protective cover, and the several annular closed holes They are arranged sequentially in the protective sleeve from top to bottom. Through the above method, the anti-scald plastic water cup of the present invention, the cooperation of the limit ring and the limit groove avoids the automatic falling off of the protective cover, and the effect of the axial reinforcement strip improves the basic plastic cup body and The protective cover has high connection strength and high stability when held, and the ring-shaped closed hole reduces the heat transfer from the inner wall of the protective cover to the outer wall, and the heat insulation effect is good to avoid burns when held.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an anti-scalding plastic water cup. Background technique [0002] With the development of plastic production technology, the materials of plastic water cups are becoming more and more safe. Compared with glass water cups, plastic water cups are more portable, not easy to break, and are widely used. [0003] The heat transfer of the plastic water cup is relatively direct. If the water temperature in the plastic water cup is high, the high temperature will be directly transmitted to the outside, and it is difficult to operate directly by hand. Therefore, some water cups are equipped with heat insulation sleeves, but ordinary heat insulation sleeves are different from the cups. The outer wall has poor fit, it is difficult to fix and it is easy to slide down, losing the effect of heat insulation. Contents of the invention [0004] The technical problem mainly solved by the present inventio...
