Pre-separation type double-cavity bottle

Abstract

The invention discloses a pre-separation type double-cavity bottle. The double-cavity bottle comprises a bottle body, an inner bottle body, a moving part, an inner bottle body, a moving part and a pressing part; a main material cavity for accommodating a first material body is formed in the bottle body; the inner bottle body is arranged at one end of the bottle body and extends into the main material cavity, a secondary material cavity used for containing a second material body is formed in the inner bottle body, and a separation film used for separating the main material cavity from the secondary material cavity is arranged on the inner bottle body; the moving part can move from a first locking position in the inner bottle body to a second locking position, a tip part is arranged at one end of the moving part, when the moving part is located at the second locking position, the tip part opens the separation film to communicate the main material cavity with the secondary material cavity, and a through hole is formed in the other end of the moving part; and the pressing part is elastically arranged outside the other end of the moving part and is used for pushing the moving part to move from the first locking position to the second locking position. Different materials are stored in different cabins and are fully mixed in the bottle before being used and can be immediately used after being discharged, the separation film are prevented from falling off, and the use experience is good.

Description

technical field [0001] The invention relates to the technical field of cosmetic containers, in particular to a pre-separated double-chamber bottle. Background technique [0002] With the continuous improvement of consumers' requirements for skin care products, they not only require skin care products to have functions such as cleaning and moisturizing, but also hope to remove wrinkles and enhance skin elasticity. Cosmetic manufacturers have begun to use a large number of natural active ingredients in the production of skin care products. However, these active ingredients have high requirements for preservation and require a separate cavity for preservation to prevent inactivation. Among the commercially available skin care products, there is a type of product that contains two or more types of ingredients, one of which is a highly active ingredient. At present, there are usually two ways to package and use this type of product: 1) Different active ingredients are packaged i...

Problems solved by technology

[0004] The first object of the present invention is to provide a pre-separated double-chamber bottle in order to overcome the problem that the double-chamber bottle of the prior art needs to mix different materials by itself, and the operation steps are cumbersome. Fully mixed inside, can be used immediately after discharge

[0005] The second object of the present invention is to provide a pre-separated double-chamber bottle for rapid mixing of materials, in order to overcome the problem that the double-chamber bottle sealing plug in the prior art is too tightly fitted to cause difficulty in disengagement, or too loosely fitted to cause leakage.
