Volume-variable type double-lid cup

Abstract

The invention discloses a volume-variable type double-lid cup. The bottom of the cup is designed as a cup lid, and thus the double-lid cup is formed. Three annular grooves with equal distances are formed inside a cup body of the cup. An elastic film is clamped in any position of the annular grooves through extruding pieces, and accordingly the volume varying function is achieved. The rigid hollow pipe ends of exterior clamping rods stretch into the cup, and the clamping rods clamping an elastic film presser enable a spring in the presser to be compressed, so that the two interior extruding pieces close up, the elastic film contracts, the volume of the elastic film presser is decreased, and the elastic film presser can move in the cup after a certain volume is decreased; and when the elastic film presser moves to the other positions of the annular grooves, the exterior clamping rods are taken out, the spring extends to enable the interior extruding pieces to extrude the elastic film, and accordingly the sealing function is achieved.

Description

technical field [0001] The present invention is a variable volume double-covered cup. Background technique [0002] The main function of a cup (a vessel for holding water) is to drink wine or tea from ancient times to the present. Most of the basic vessels are straight or open, and the diameter of the rim is almost equal to the height of the cup. Comes with flat, circle or tall feet. According to different production materials, it can be divided into glass cups, plastic cups, ceramic cups, wooden cups, etc. [0003] With the improvement of modern people's living standards, ordinary single-head, fixed-volume cups can no longer meet the needs of modern people's lives, especially when traveling outdoors, people always hope to carry less things, such as cups, Some people may want to drink tea of ​​different tastes (such as black tea and green tea), but do not want to carry two cups, and also want to drink more green tea and less black tea, or want to drink equal volumes of bl...
