Dropper bottle

Abstract

The invention discloses a dropper bottle which comprises a bottle cap and a bottle body, the bottle cap comprises a stepped-shaft-shaped lining, a piston and a suction pipe are arranged in the lining, the lower end of the suction pipe extends into the bottle body, the upper portion of the lining is sleeved with a thread sleeve, a notch is formed in the circumferential face of the thread sleeve, the upper portion of the notch is an inclined face, and the size of the left end of the notch is smaller than that of the right end of the notch. The upper portion of the threaded sleeve is sleeved with a pressing block, the pressing block comprises an inner rod and an outer ring which are concentric, a pin column is arranged on the periphery of the outer ring and located in the notch, the inner rod stretches into the lining and is in interference fit with the piston, the periphery of the threaded sleeve is rotationally connected with an outer sleeve, and a prism is arranged on the inner wall of the outer sleeve. The volume of the absorbed cosmetic liquid can be quantitatively controlled.

Description

technical field [0001] The invention relates to the technical field of cosmetic packaging, in particular to a dropper bottle. Background technique [0002] Existing cosmetic liquid containing devices generally include a bottle body and a cover that is sealed and matched with the bottle body. When in use, the cover needs to be opened to pour out the cosmetic liquid. For liquids such as essential oils, the amount taken each time is relatively small, and dumping will inevitably cause waste, so dropper bottles have appeared on the market to solve the problem of taking a small amount of liquid. Existing dropper bottles include two structures: extrusion type and knob type. The extrusion head used in the extrusion type is mostly made of rubber, which will cause aging after a long period of use. Therefore, the knob type is more common. The structure of the existing knob is to squeeze the gas in the straw while screwing the bottle cap, and to suck the essential oil while unscrewing ...

For liquids such as essential oils, the amount taken each time is relatively small, and dumping will inevitably cause waste, so dropper bottles have appeared on the market to solve the problem of taking a small amount of liquid

Existing dropper bottles include two structures: extrusion type and knob type. The extrusion head used in the extrusion type is mostly made of rubber, which will cause aging after a long period of use. Therefore, the knob type is more common. The structure of the existing knob is to squeeze the gas in the straw while screwing the bottle cap, and to suck the essential oil while unscrewing the bottle cap, so as to complete the taking of the cosmetic liquid, but this structure has certain The problem: the bottle cap always rotates to the bottom when it is closed, so that the amount of suction is constant, and the liquid capacity of each suction cannot be changed. It is difficult to quantitatively absorb the makeup liquid, which will cause a certain amount of waste
