Liquid and powder negative pressure mixing device

Abstract

A liquid-powder negative pressure mixing device includes a powder bottle, a stopper, an outer seal, and an alignment kit. The powder bottle includes a bottle body, a mixing space defined by the bottle body and capable of holding a powder, and a bottle opening communicating with the mixing space. The stopper includes a plug body, a channel communicatingly disposed in the plug body, and a top connecting the plug body and closing the channel. The plug body is inserted into the bottle opening to seal the mixing space, which is then configured into a negative pressure state. The outer seal includes a ring portion fixed to the bottle opening and a cap ring connecting to the ring portion and pressed against the top of the plug body, exposing a puncture area. The alignment kit includes a connecting portion connecting to the cap ring and a collar disposed at the end of the connecting portion away from the cap ring.

Claims

1. A liquid and powder negative pressure mixing device, comprising: a powder bottle, including a bottle body, a mixing space defined by the bottle body and capable of storing a powder, and a bottle opening communicating with the mixing space; a stopper, including a stopper body, a channel communicatingly disposed in the stopper body, and a top connected to the stopper body and closing the channel, the stopper body being inserted into the bottle opening to seal the mixing space, the mixing space being configured to a negative pressure state after being closed, the top having a puncture area aligned with the channel, the puncture area being a thin portion and having a pre-indentation on the side near the mixing space, the thin portion and the pre-indentation being recessed when the mixing space is in a negative pressure state, the puncture area being punctured by a dropper nozzle of a dropper bottle; An outer sealing component includes a ring portion fixed to the bottle opening, a cap ring connected to the ring portion and pressed against the top of the stopper body, exposing the puncture area, the cap ring including a hollow portion and a positioning hole protruding radially from the hollow portion; and a matching kit including a connecting portion connected to the cap ring and a collar disposed at one end of the connecting portion away from the cap ring, the connecting portion having a positioning protrusion corresponding to the hollow portion and a positioning protrusion protruding radially from the positioning protrusion, the positioning protrusion being disposed corresponding to the positioning hole when the positioning protrusion is connected to the hollow portion, thereby restricting the matching kit from rotating axially relative to the outer sealing component. After the dropper bottle is detachably fixed to the collar, the dropper nozzle passes through the positioning protrusion and the hollow portion and punctures the puncture area, extending into the channel and communicating with the mixing space.

2. The liquid and powder negative pressure mixing device as described in claim 1, wherein, It also includes a cap that can be detachably covered and closed the end of the collar away from the connection.

3. The liquid and powder negative pressure mixing device as described in claim 1, wherein, The ring is press-fitted to the outer edge of the bottle opening.

4. The liquid and powder negative pressure mixing device as described in claim 1, wherein, The connection part of the alignment kit is heat-fused to the cover ring.

5. The liquid and powder negative pressure mixing device as described in claim 1, wherein, The cap ring includes a ring body and a flap that partially connects to the ring body. The flap is configured to be torn in one direction to break the outer seal and remove it from the powder bottle.

6. The liquid and powder negative pressure mixing device as described in claim 5, wherein, The connection part of the alignment kit is heat-fused to the lifting part.

7. The liquid and powder negative pressure mixing device as described in claim 5, wherein, The cover ring has multiple annularly spaced gaps between the flap and the ring body that extend through the cover ring.

8. The liquid and powder negative pressure mixing device as described in claim 7, wherein, The outer seal also has multiple guide indentations located on the ring portion and the cover ring and respectively connected to any of the gaps.

9. The liquid and powder negative pressure mixing device as described in claim 1, wherein, The pre-indentation is a groove.

10. The liquid and powder negative pressure mixing device as described in claim 9, wherein, The groove can be either straight or cross-shaped.

11. The liquid and powder negative pressure mixing device as described in claim 1, wherein, The connecting part of the alignment kit is first heat-fused to the cap ring of the outer seal, and then the ring of the outer seal is fixed to an outer edge of the bottle mouth by pressing.
