Leak-proof straw

Abstract

A leak-proof straw mainly comprises a pipe body, the lower end of the pipe body is inserted into a milk box, a suction opening corresponding to the pipe body is formed in the upper end of the milk box, a vertical inner ring plate is connected with the upper end of the suction opening in the circumferential direction in a sleeving mode, the inner ring plate is fixed to the milk box and sleeved withan outer ring plate. An opening gap is reserved between the outer ring plate and the inner ring plate, the outer ring plate is connected with the circumference at the upper end of the inner ring plate through an annular slide-in ring plate, a screw cap is connected with the outer end of the outer ring plate, the pipe body is sleeved with a rubber sleeve, and the lower end of the rubber sleeve isfixed to the screw cap. In use, the pipe body is sleeved with the screw cap and the rubber sleeve, the lower end of the pipe body is inserted into the milk box from the suction opening, the pipe bodyis convenient inserted into the milk box due to the arrangement of the annular slide-in ring plate, the pipe body continues to move downwards, then the outer ring plate is sleeved with the screw cap,the screw cap is screwed, so that the screw cap is tightly squeezed on the pipe body under the elastic force of the rubber sleeve, and when the milk box is squeezed, the side leakage phenomenon of milk cannot occur.

Description

technical field [0001] The invention relates to the field of straws, in particular to a leak-proof straw. Background technique [0002] Milk is rich in nutrition, easy to digest and absorb, high in quality and low in price, and convenient to eat. It is the most "close to perfect food". It is called "white blood" and is the most ideal natural food. The protein in milk is mainly casein, albumin, globulin, milk protein, etc. Among the more than 20 kinds of amino acids contained in it, there are 8 kinds of amino acids necessary for the human body. Milk protein is a complete protein, and its digestibility is as high as 98%. . Milk fat is a high-quality fat with the best quality. Its digestibility is above 95%, and it contains a lot of fat-soluble vitamins. Lactose in milk is galactose and lactose, which are the most easily digested and absorbed sugars. Minerals and trace elements in milk are in a dissolved state, and the content ratio of various minerals, especially the ratio ...

AI Technical Summary

Problems solved by technology

There are a lot of milk on the market now, both bottled and boxed. For boxed milk, the cost is relatively low, and it is made of paper shells. When using boxed milk, straws are needed. A tube with a bent tube. After the milk carton is tied open, the gap will become larger. When a person holds the milk carton, walks or hits it, if he accidentally uses force, the milk will spill from the insertion of the straw , it's more troublesome to sprinkle
