Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, in particular to a piston vacuum bottle with light-shielding and visible liquid level. Background Art

[0002] A vacuum bottle usually consists of a cylindrical container and a piston arranged at the bottom. The vacuum bottle can completely isolate the content from air, avoiding product oxidation, deterioration and bacterial growth due to contact with air. Its design principle is to utilize the contraction force of a spring and prevent air from entering the bottle to create a vacuum state, and then use atmospheric pressure to push the piston at the bottom of the bottle forward.

[0003] In the prior art, the bottle body usually extends downward towards the piston to form a bottle bottom. When assembling the existing vacuum bottle, the piston can only be installed into the bottle body from the bottle mouth first, and then components such as a pump head and a nozzle are assembled at the bottle mouth. This not only limits the installation sequence of the piston, but also makes it very inconvenient to adjust and repair the piston after assembly. Moreover, in order to facilitate the installation of the piston from the bottle mouth, the bottle mouth must be opened large enough, which places a size limit on the pump head and nozzle assembled at the bottle mouth.
