Description

TECHNICAL FIELD

[0001] The utility model relates to a dropper type vacuum bottle, which is a press type telescopic pump head vacuum bottle. BACKGROUND

[0002] A vacuum bottle refers to a container that can isolate gas from the outside temperature or a container that can isolate external bacteria. The vacuum bottles sold on the market are composed of an elliptical container with a cylindrical body and a piston placed at the bottom. The working principle is mainly to use the contraction force of the spring, prevent air from entering the bottle, and create a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward. A dropper refers to a device that allows liquid stored in the bottle to flow out in a drop-by-drop manner through a dropper head. Such a dropper generally has a drop-by-drop tube or a drop-by-drop pipe that is used independently and inserted into the bottle opening. By pressing the rubber head of the drop-by-drop tube or the drop-by-drop pipe, the liquid is sucked into or discharged through the dropper of the drop-by-drop tube. Some cosmetic containers combine a vacuum bottle with a dropper, such as the patent document CN202311534893.3, granted on March 12, 2024, with the utility model name "Multi-functional vacuum replacement dropper container with precise quantitative slow-dripping liquid and multiple leakage prevention".
