Anti-releasing heat-insulating cup sleeve

Abstract

The invention discloses an anti-falling heat-insulating cup sleeve, which comprises: a first plastic sleeve, a second plastic sleeve is arranged under the first plastic sleeve, and several ring-shaped sleeves are arranged in the sleeve wall of the first plastic sleeve. Air holes, the several annular air holes are sequentially arranged in the wall of the first plastic sleeve from top to bottom, the wall thickness of the second plastic sleeve is smaller than the wall thickness of the first plastic sleeve, and the wall thickness of the second plastic sleeve The inner hole and the inner hole of the first plastic sleeve are respectively cylindrical holes or tapered holes. Through the above method, the anti-falling heat-insulating cup sleeve of the present invention is made of soft plastic material. Under the action of the annular air hole, the heat insulation effect is good, and the outer handle is tough. The inner hole of the second plastic sleeve The size is small, the wall thickness is thin, and the fit with the cup is tighter, which avoids the problem of the first plastic sleeve falling off.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a fall-off-proof heat-insulating cup sleeve. 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 handle is stiff, 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, which affects the stability of use.
