Plastic sleeve for anti-skid protection

Abstract

The invention discloses a plastic sleeve for anti-skid protection. The plastic sleeve comprises a plastic sleeve base body, multiple conical sucker structural holes are formed in the inner wall of the plastic sleeve base body, a circle of annular holes are formed in the plastic sleeve base body, vent holes connected with the annular holes are formed in the middle positions of the multiple conical sucker structural holes, and an arc positioning groove corresponding to the annular holes is formed in the outer wall of the plastic sleeve base body in an inward concave mode. By means of the mode, the annular holes reduce the weight of the plastic sleeve base body of the plastic sleeve for anti-skid protection, reduce heat transmission efficiency and improve the heat insulation effect, the plastic sleeve is arranged on a cup in a sleeving mode, the arc positioning groove is pressed to extrude part of air in the annular holes, the annular holes are reset elastically when the fingers loosen, negative pressure is formed in the annular holes, the plastic sleeve is adsorbed on the surface of the cup by means of the conical sucker structural holes, connection between the plastic sleeve and the cup is enhanced, and the plastic sleeve base body is prevented from falling.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a plastic sleeve for anti-slip protection. 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 have a solid structure , the heat insulation effect is poor, and it is difficult to fix on the outer wall of the cup and it is easy to slide, and the use stability is poor. Contents of the invention [0004] The technical problem mainly...

[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 of solid structure , the heat insulation effect is poor, and it is difficult to fix on the outer wall of the cup and it is easy to slide, and the use stability is poor
