TECHNICAL FIELD
[0001] The utility model relates to the technical field of cream bottle, more particularly to the vacuum glass cream bottle with replaceable inner container. BACKGROUND
[0002] At present, the cream bottle on the market is generally composed of a bottle body and a bottle cap, and has the problem of inconvenient material taking. When taking the material, the cream is taken out by hand, which not only cannot limit the amount of the cream used, but also pollutes the clean cream inside, affecting use. Further, a vacuum cream bottle through a pressing mode is provided. The vacuum cream bottle uses atmospheric pressure to push the piston at the bottom forward, so that the product does not contact air and bacteria during use, avoids oxidation and deterioration of the product caused by contact with air, and keeps the freshness of the product for a long time. However, when the cream vacuum bottle is used up, it is inconvenient to refill the cream. Most cream vacuum bottles are discarded, and some people propose to set a replaceable inner container in the cream vacuum bottle to store the cream in the inner container. When the cream in the inner container is used up, the inner container is directly replaced, and the outer bottle structure can be reused to reduce the generation of garbage and improve the utilization of resources. Therefore, it is necessary to design a vacuum cream bottle with replaceable inner container.
