Technical field

The present invention relates to a cosmetic container.

Background technique

With the advancement of science and technology, the structural design of packaging supplies has become more and more sophisticated, and it is not only satisfied with the function of containing products. As a new type of packaging structure, multi-liquid packaging bottles have broad application prospects and can be used in fields such as medicine, cosmetics, and detergents. Multi-element liquid packaging bottles can separate and package liquids with different chemical properties, and only mix them when used. This can not only stabilize the chemical properties of various liquids during storage, but also prevent various adverse consequences caused by mixing various liquids. , such as the product efficacy is reduced, the storage time of packaged liquid is greatly shortened, etc.

To achieve separate packaging of various liquids, the simplest method is to separate the packaging bottles into multiple cavities with partitions. However, the packaging structure is too simple and cannot achieve liquid mixing when the liquid is poured out. The liquid needs to be poured in first. It is very inconvenient to use it inside a container. In order to solve this problem, the Chinese utility model patent "A Double-Cavity Pump Type Packaging Bottle" with the authorization announcement number CN206013408U provides a structure in which a bottle cap is fastened at the mouth of the bottle body, and the bottle body is provided with a The partition divides the bottle body into two cavities. The bottle cap is fixed with two pump bodies. The upper end of the pump body is provided with a pump head cover. The pump head cover is provided with a pump head mouth. The pump head cover is set on The outer tube of the pump body can slide along the outer tube. The lower end of the pump body is connected to the catheter tube. The catheter tubes are respectively located in the two cavities of the bottle body. The pump body includes an outer tube fixedly mounted on the bottle cap. A pump head, a spring and a fixing piece are arranged in the tube from top to bottom, and a ball is arranged on the fixing piece. The above-mentioned double-chamber pump packaging bottle can realize the mixing of two liquids by simply pressing it. However, it cannot mix the two liquids in advance. It is not suitable for cosmetics such as essences and energy liquids that need to be pre-mixed during use. Be applicable.

Therefore, the current liquid container structure that can realize dual-cavity packaging needs to be further improved.

Contents of the invention

The technical problem to be solved by the present invention is to provide a cosmetic container which can package two liquids separately before leaving the factory and pre-mix the two liquids before use, thereby extending the shelf life of the cosmetics and improving the use effect.

The technical solution adopted by the present invention to solve the above technical problems is: a cosmetic container, which includes a bottle body and a nozzle. The nozzle is located at the mouth of the bottle body and is used to pump out the material in the bottle body. It is characterized by: It also includes a sleeve, an upper piston and a lower piston. The nozzle is arranged at the mouth of the bottle so as to move up and down. The sleeve is arranged in the bottle and its upper end is connected to the suction port at the lower end of the nozzle and moves synchronously with the nozzle. The lower end of the casing extends toward the bottom of the bottle; the upper piston is placed between the upper part of the casing and the upper part of the bottle; the lower piston is movable up and down at the bottom of the bottle and is connected to the inner wall of the bottle and the upper piston. A vacuum sealing cavity for encapsulating the first liquid is formed in between, the lower piston is hollow inside to form a receiving cavity for holding the second liquid, the top of the lower piston is open and covered with a sealing film, and the sleeve The lower end is provided with a puncture structure capable of puncturing the sealing film in a downwardly moving state.

As an improvement, the edge of the lower port of the sleeve extends radially outward to form a puncture ring arranged corresponding to the sealing film. The middle part of the lower wall surface of the puncture ring is arranged circumferentially and divides the puncture ring into inner rings. and the guide groove of the outer ring, the lower wall surface of the inner ring and the lower wall surface of the outer ring are both provided with the puncture structure. Using the above structure, when the inner bottom wall of the lower piston of the present invention is in contact with the lower wall of the puncture ring, if the mixed liquid in the bottle has not been used up, it can enter the casing through the puncture structure and the guide groove and be pumped out. , and the puncture ring can increase the contact area with the inner bottom wall of the lower piston. Through the guidance and adsorption of the puncture structure, all the liquid on the edge of the lower piston is sucked into the casing and output, which is conducive to the effective use of the liquid in the bottle. ,Prevent wastage.

The head cap is provided with a liquid outlet channel connected to the upper port of the pump core assembly. The rotating sleeve has a There is an opening at the top for the head cap to extend or retract. In the factory state, the head cap is extended out of the top of the rotating sleeve. When in use, the rotating sleeve is rotated. Since the guide sleeve does not move, the rotating sleeve transmits force to the rotating ring through the second slide groove, causing the guide column to move along the first sliding groove. The groove and the second chute slide, and the rotating ring drives the pump core assembly, head cap, and casing to move downward until the head cap shrinks in the opening of the rotating sleeve and the piercing structure at the lower end of the casing pierces the sealing film; then reverse the direction Rotate the rotating sleeve until the head cap extends out of the opening of the rotating sleeve. At this time, you can press the head cap to take out the mixed cosmetics.
