Anti-scalding plastic water cup assembly

Abstract

The invention discloses an anti-scalding plastic water cup assembly. The anti-scalding plastic water cup assembly comprises a base plastic cup body and an outer protective sleeve; the outer protective sleeve is concentrically arranged outside the base plastic cup body; a plurality of heat insulating rings are arranged between the base plastic cup body and the outer protective sleeve; the heat insulating rings are annular hollow plastic pipes or annular foamed plastic pipes; a limiting embedded groove is formed in the outer wall of the base plastic cup body; a limiting ring which extends into the limiting embedded groove is arranged on the inner wall of the outer protective sleeve. In the mode, the outer protective sleeve is prevented from falling off naturally through the cooperation of the limiting embedded groove and the limiting ring of the anti-scalding plastic water cup assembly disclosed by the invention; the using stability is high; the heating of the base plastic cup body to the outer protective sleeve can be reduced by the heat insulating rings, so that the temperature of the outer protective sleeve is relatively low; the anti-scalding plastic water cup assembly can be hold more safely in a hand.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an anti-scalding plastic water cup assembly. 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 plastic water cups 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 not the same as the cups. The outer wall has poor compatibility, it is difficult to fix and it is easy to fall off automatically, and the effect of heat insulation is lost. In addition, the heat insulating sleeve is heated when it is at...

Problems solved by technology

[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 compatibility, it is difficult to fix and it is easy to fall off automatically, losing the effect of heat insulation. In addition, the heat insulation sleeve is heated when it is attached to the cup, which will cause the temperature of the heat insulation sleeve to rise, and the danger of holding it is high.
