Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic container manufacturing, in particular to a cosmetic container. Background Art

[0002] Common liquid cosmetic containers on the market today are usually composed of a bottle body, a bottle cap, and a sealing base disposed under the bottle body, and the sealing base is installed in the bottle body, so that the bottle body, the bottle cap, and the sealing base form a sealed assembly. In particular, containers for storing liquid cosmetics usually store the liquid cosmetics in the bottle body.

[0003] The prior art has some shortcomings, especially taking liquid cosmetic containers as an example. In order to avoid the sealing problem, the cosmetic containers of the prior art often have a very complicated design of the sealing structure. The sealing base of the traditional liquid cosmetic container is set into the container with a large amount of air pressure. When filling, the upper cover is sealed, the material is filled from the lower opening, and then the sealing base is pressed into the bottom opening of the bottle. After filling, the pressure in the bottle is high, and the user needs to spend a lot of effort to open the sealed container, which is very inconvenient to use. When the bottle cap is opened for the first time, the liquid cosmetics are prone to splashing. In addition, conventional cosmetic containers use a sealing base for filling. After filling, the sealing base is pressed into the bottom opening of the bottle, and it cannot be refilled and reused, resulting in a waste of resources.

[0004] CN207220433U discloses a sealing structure for cosmetics. It includes a longitudinal axis and a normal plane perpendicular to the longitudinal axis, a first container, a second container, an intermediate body and a sealing device. The intermediate body includes a base and an applicator. The first container can be connected to the second container to form a container with a closed inner cavity and can be opened. When the container is closed, part of the intermediate body is arranged in the second container, and part of the intermediate body is also arranged in the first container. The second container and the first container are connected by a fastening device. The sealing device includes a sealing member and a supporting base. When the container is closed, the sealing member and the supporting base are in contact and arranged relative to each other to ensure the airtightness of the sealed container. The sealing device and the fastening device are arranged at intervals along the longitudinal axis. The cosmetic container can be opened quickly and conveniently without much effort, but there is still a problem that it cannot be reused, resulting in waste.

[0005] Therefore, finding a reusable cosmetic container with low pressure inside the bottle is a problem that needs to be solved at present. Utility Model Content
