Portable cup outer appliance based on double-layer heat preservation and insulation structure

Abstract

The invention discloses a portable cup outer appliance based on a double-layer heat preservation and insulation structure, which is characterized in that: a zipper is sewn on the upper front side of the sleeve body; a hand strap is sewn on the upper part of the left side of the sleeve body; the left end of the strap is sewn on the upper part of the left side of the sleeve body, and the right end of the strap is sewn on the upper part of the right side of the sleeve body. The sleeve body is made of a surface layer, an insulation layer and an insulation layer by stitching, and the sleeve body issequentially arranged as a surface layer, an insulation layer and an insulation layer from the outside to the inside. When the water cup is to be filled, the water cup is simply put into the sleeve body from the zipper, and the zipper is zipped through the slider, and the heat insulation layer and the heat insulation layer of the sleeve body can be used for realizing the double-layer heat insulation and heat insulation of the water cup. While the carrying mode can choose the oblique span of the strap, the adjustable buckle can be adjusted when the strap length is inappropriate. The strap canalso be hung on your hand. If you carry the bag, you can put it in the bag or hang it on the slider of the bag with a hook. The invention has the advantages of simple structure, novelty and suitable for popularization.

Description

technical field [0001] The invention relates to cup sleeves, in particular to the field of portable cup utensils based on a double-layer thermal insulation structure. Background technique [0002] At present, water cups go deep into every corner as daily necessities, especially people often take a water cup with them when they go out. The water cup cover that has technology can't carry out double-layer insulation, heat insulation to water quilt. Simultaneously, the water cup sleeve of the prior art has a single carrying mode, which is inconvenient for people to carry in various situations. This brings inconvenience to people's lives. Contents of the invention [0003] The present invention aims to solve the problem that the existing water cup cover cannot carry out double-layer heat preservation and heat insulation for the water cup, and is not easy to carry, and provides a portable cup outer appliance based on a double-layer heat preservation and heat insulation structu...
