Anti-scalding plastic cup

Abstract

The invention discloses an anti-scalding plastic cup. The anti-scalding plastic cup comprises a basic plastic cup body and a protecting cover, wherein the protecting cover is arranged on the outer side of the basic plastic cup body and is concentric with the basic plastic cup body, a circular limiting groove is formed in the outer wall of the basic plastic cup body, a limiting ring corresponding to the limiting groove is arranged at the bottom of the protecting cover, and a plurality of annular closing holes are formed in the protecting cover and are sequentially distributed in the protecting cover from top to bottom. By means of the scheme of the anti-scalding plastic cup, through cooperation of the limiting ring and the limiting groove, automatic falling of the protecting cover is avoided, the connection strength of the plastic cup body and the protecting cover is improved through the function of axial reinforcing strips, the stability is high when the plastic cup is held by a hand, transferring of heat from the inner wall of the protecting cover to the outer wall is reduced by the aid of the annular closing holes, the heat insulation effect is good, and the scalding problem during holding by hand is solved.

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.
