Description

Technical Field

[0001] The utility model belongs to the technical field of food processing tools, in particular to a cream gun bottle cap. Background Art

[0002] The food spray guns currently on the market are mainly cream spray guns or cream foaming guns, which are commonly found in restaurants, bars, coffee shops and other places. Users need to prepare the cream first, then pour the cream into the gun body, tighten the cap, and use a 200bar gas cartridge to fill the bottle with high-pressure gas through the air inlet device on the cream gun head. When using, press the handle of the spray gun to spray the cream.

[0003] In the existing design, a high-pressure gas bomb is needed to inject high-pressure gas into the bottle. Since high-pressure gas is dangerous, the safety design requirements for the air intake device are relatively high. At the same time, for safety purposes, the cream gun is usually made of metal, and the bottle wall is thick. In practice, metal materials are generally used.

[0004] In order to ensure the stability of the cream gun structure, the bottle cap (gun head) of the cream gun is also made of metal material; however, the bottle cap of the traditional cream gun and the outer valve sleeve on the bottle cap are split structures, which can easily affect the overall sealing and safety of the cream gun when the processing accuracy is not high.
