The invention provides an elliptical tooth plastic hose assembly, which comprises a hose body, an inner lining and an outer cover shell. The hose body, the outer cover shell and the inner lining are all elliptical, the inner lining is embedded in the outer cover shell in a clamped mode, the upper end of the hose body is provided with a horizontal platform, an elliptical step is arranged on the horizontal platform, an elliptical base plate sleeves the outer side of the elliptical step, first limiting clamping blocks are arranged on the elliptical step, the lower end of the base plate is provided with raised second limiting clamping blocks, and when the base plate rotates, the second limiting clamping blocks can abut against the first limiting clamping blocks to hinder the base plate from continuing rotating; and locking grooves are formed in the upper end of the base plate, the lower end of the inner lining is provided with raised locking blocks, the locking blocks can be clamped into the locking grooves, a concave elliptical groove is formed in the lower bottom surface of the base plate, an elastic rubber cushion is placed in the elliptical groove, and the lower end face of the rubber cushion abuts against the horizontal platform. Safety is high, the inner lining can be unlocked by downwards pressing the base plate, otherwise the inner lining and the base plate can only rotatewithin the range of 180 degrees, and the outer cover shell cannot be opened.
Description
Technical field [0001] The invention belongs to the technical field of plastic packaging bottles, and relates to an oval dental plastic hose assembly. Background technique [0002] At present, most cosmetic hoses are composed of a tube body and a tube cap screwed on the tube body. The inside of the tube body is filled with cosmetic liquid. The bottom of the tube body is closed by pressing, and the end of the tube body is provided with a liquid outlet port. The emulsion is squeezed out by squeezing the body of the tube. If the cosmetic hose is placed casually, it is easy for children to play with it. It is very likely that the child will accidentally drink the cosmetics into the stomach by opening the lid, which will easily cause the child to be poisoned or cause damage to the child’s digestive tract mucosa. For this, people have designed some Bottles that prevent accidental opening. [0003] For example, a Chinese invention patent [CN201921259226.8] discloses a special inner and ...
