Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:

[0017] As shown in the figure, the vacuum bottle includes a bottle body 1 with a cavity 13, a spray head 2 with a first cavity 21 inside, a transmission rod 3 with a second cavity 31 inside, and a piston 4; the upper part of the bottle body is set There is an opening, and the opening is elastically provided with a valve block 5 to block the opening; the spray head can be connected to the upper end of the bottle body in a reciprocating manner along the axial direction of the bottle body, and the transmission rod 3 is connected to the lower end of the spray head. Specifically, the transmission rod 3 can be used to Plug in the end of the first cavity or connect the transmission rod to the lower end of the nozzle so that the second cavity communicates with the first cavity, and the lower end of the transmission rod is opposite to the valve block, an...

Abstract

The invention relates to a vacuum flask. The vacuum flask comprises a flask body with a containing cavity, a sprayer internally provided with a first cavity channel, a transmission rod internally provided with a second cavity channel and a piston. An opening is formed in the upper portion of the flask body. A valve block for sealing the opening is elastically arranged in the opening. The sprayer can be connected to the upper end of the flask body in a reciprocating mode in the axial direction of the flask body, the transmission rod is connected to the lower end of the sprayer, the second cavity channel and the first cavity channel are communicated, the lower end of the transmission rod is opposite to the valve block, and the diameter of the transmission rod is smaller than that of the valve block. The piston is arranged at the bottom of the flask body in a sliding mode. The diameter of the piston is the same as the internal diameter of the flask body. The bottom side of the piston is elastically connected with the flask bottom of the flask body through a compression spring. Power is supplied to liquid, emulsion and paste in the flask body through the piston via the compression spring, it is only needed to push the valve block to enable a channel to be formed between the containing cavity and the sprayer, the liquid, emulsion and paste can be sprayed out, and operation is simple.

Description

technical field [0001] The present invention relates to the field of packaging products of liquid or emulsion or paste, especially a vacuum bottle. Background technique [0002] At present, the common packaging forms of liquids, emulsions and pastes in the market are vacuum bottles. A vacuum bottle refers to a container that can isolate gas from the outside temperature or a container that isolates external bacteria. The cylinder is formed into an ellipsoid container plus a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, since the spring force and atmospheric pressure cannot give enough force, the remaining emulsion is difficult to be pressed out, and continuous pressing is required to spray the emulsion, the structure is complicated, and the production cost is hi...
