Description

Technical Field

[0001] This utility model relates to a freeze-dried powder packaging container, specifically a puncture-type freeze-dried powder bottle with smooth liquid flow. Background Technology

[0002] Freeze-dried powder is a skincare product made using freeze-drying technology. It is typically sold and used in conjunction with a specially formulated solvent. The finished freeze-dried powder is packaged in a medicine bottle, which also contains a medicine bottle with the solvent. To use, both the freeze-dried powder bottle and the solvent bottle are opened separately, and the solvent is poured into the freeze-dried powder bottle, mixed, and then used.

[0003] Because using two bottles is cumbersome, many manufacturers have begun developing dual-chamber containers that can separately hold lyophilized powder and solvent liquid. Detailed structures can be found in Chinese utility model patent publication number CN221024755U. This technical solution involves a first chamber and a second chamber within the container. The first chamber stores the outer solution medium of the cosmetic, while the second chamber stores the lyophilized powder medium. A movable sealing seat with an aluminum foil is installed inside the container. The aluminum foil effectively separates the first and second chambers. The two ends of the movable sealing seat can slide up and down inside the outer bottle, causing the aluminum foil to move towards a sharp-edged post. This allows the post to pierce the aluminum foil, connecting the first and second chambers. The outer solution stored in the first chamber flows into the second chamber and mixes with the lyophilized powder, resulting in a freshly mixed active cosmetic solution. This structure allows for simple and rapid mixing of lyophilized powder and has gained market acceptance. However, during use, it was found that the freeze-dried paste formed after mixing the freeze-dried powder and the solution medium had poor fluidity, requiring a long wait before it could be poured out of the nozzle. After research, the inventors discovered that when the paste flowed in one direction, gas could not enter the other side, creating a vacuum on that side and making it even more difficult for the paste to flow out. Therefore, the inventors improved the aforementioned structure. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a puncture-sprayed freeze-dried powder bottle with smooth liquid flow.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A puncture-resistant freeze-dried powder bottle with smooth liquid flow includes: a first cavity and a second cavity, the first cavity and the second cavity being connected to each other by a connector, one end of the second cavity being provided with a dispensing nozzle and the other end being provided with a puncture port, and one end of the first cavity being provided with a bottle mouth facing the puncture port, characterized in that: a conduit extending from the bottle mouth to the bottom of the first cavity is provided in the first cavity, and a dispensing area is formed between the inner wall of the bottle mouth of the first cavity and the outer wall of the conduit.

[0007] In this invention, the first cavity is located inside the lower bottle, and the upper part of the conduit is provided with a connecting seat, which is connected to the bottle mouth. The connecting seat is provided with a material passage hole that communicates with the discharge area.

[0008] In this invention, the connecting seat has a puncture area larger than the outer diameter of the puncture opening.

[0009] In this utility model, the lower bottle body includes a lower inner bottle and a lower outer bottle, the first cavity is located inside the lower inner bottle, and a silicone gasket is provided between the connecting seat and the lower inner bottle.

[0010] In this utility model, the lower outer bottle is provided with a connecting cavity, the upper part of the connecting cavity is provided with a connecting step, the main body of the lower inner bottle is inserted into the connecting cavity, the bottle mouth of the lower inner bottle is provided with a connecting ring, the connecting ring is pressed on the connecting step, the silicone gasket is pressed on the connecting ring, the outer side of the silicone gasket abuts against the inner wall of the connecting cavity, and the bottom of the connecting seat is pressed on the silicone gasket.

[0011] In this invention, the top of the connecting seat is provided with a sealing film.

[0012] In this invention, there is a gap between the conduit and the bottom of the first cavity.

[0013] In this invention, the catheter is located on one side of the first cavity and is closely attached to the inner wall of the first cavity.

[0014] In this invention, the cross-sectional area of ​​the inner bore of the conduit is smaller than the cross-sectional area of ​​the discharge zone.

[0015] The beneficial effects of this invention are as follows: When the piercing port of the second cavity pierces the sealing film and enters the first cavity, the medium in the second cavity falls into the first cavity under the action of gravity and mixes with the medium in the first cavity to form a mixed paste or mixed liquid. Then, the entire freeze-dried powder bottle is rotated so that the discharge nozzle faces downwards at an angle. Under the action of gravity, the mixed paste or mixed liquid flows outwards along the bottle opening of the first cavity. During the outflow process, air enters the bottom of the first cavity in time through the conduit, filling the cavity after the mixed paste or mixed liquid has flowed out, avoiding the formation of a vacuum at the bottom of the first cavity that would interfere with the flow of the mixed paste or mixed liquid, thereby accelerating the outflow speed of the mixed paste or mixed liquid and reducing the user's waiting time.

[0025] Reference Figures 1 to 8 This embodiment provides a puncture-resistant lyophilized powder bottle with smooth liquid flow, comprising an upper bottle body and a lower bottle body, wherein the lower bottle body is provided with a first cavity 1 for storing the lyophilized powder. (See attached...) Figure 4Looking at the direction, a sealing film 11 is provided at the opening of the upper part of the first cavity 1; the upper bottle contains a second cavity 2 for storing solvent liquid, the second cavity 2 and the first cavity 1 are arranged opposite each other, and the opening of the second cavity 2 has a piercing port 21 facing the sealing film 11, the piercing port 21 is cylindrical with a beveled bottom to form a piercing head. Here, the upper bottle can also be used to store solvent liquid, and the lower bottle can be used to store lyophilized powder, with the same technical effect. The second cavity 2 is provided with a discharge nozzle 4, the outside of which is covered with a cap, and the cap has a plug that presses against the discharge nozzle 4 to increase the sealing. The upper bottle and the lower bottle are connected to each other by a connector 3, the connector 3 has a through cavity, the lower end of which is connected to the opening of the lower bottle. The other end of the cavity is slidably engaged with the piercing port 21 of the second cavity 2. The first cavity 1 is provided with a conduit 5 extending from the bottle mouth to the bottom of the first cavity 1.

[0026] In a preferred embodiment, a gap 8 exists between the conduit 5 and the bottom of the first cavity 1. The gap 8 is less than 1 cm. When the gap is too large, the effect is poor. A discharge area 15 is formed between the inner wall of the bottle opening of the first cavity 1 and the outer wall of the conduit 5. The cross-sectional area of ​​the inner hole of the conduit 5 is smaller than the cross-sectional area of ​​the discharge area 15. The inner hole diameter of the conduit 5 is less than 2 mm. When the diameter is small, the mixed paste or mixed liquid is difficult to flow in the conduit 5. The mixed paste or mixed liquid mainly flows in the discharge area 15. After the mixed paste or mixed liquid has flowed partially in the discharge area 15, a cavity is formed between the mixed paste or mixed liquid and the bottom of the first cavity 1. The mixed paste or mixed liquid still exists in the conduit 5 and will be quickly squeezed into the cavity under air pressure. At the same time, the air pressure entering the cavity will generate the force to push the mixed paste or mixed liquid out of the discharge area 15, thereby accelerating the outflow of the mixed paste or mixed liquid. The conduit 5 is located on one side of the first cavity 1 and is close to the inner wall of the first cavity 1, so that the discharge area 15 is located on the other side, which facilitates flow.

[0027] In this embodiment, the lower bottle body includes a lower inner bottle 11 and a lower outer bottle 12. The first cavity 1 is located inside the lower inner bottle 11. The upper part of the conduit 5 is provided with a connecting seat 51, which is connected to the bottle mouth. The connecting seat 51 is provided with a material passage hole 52 communicating with the discharge area 15. The conduit 5 and the connecting seat 51 are integrally formed. During assembly, it is only necessary to insert the connecting seat 51 into the lower bottle body, which is convenient and quick to install.

[0028] In this embodiment, the connecting seat 51 is located between the first cavity 1 and the second cavity 2, directly below the piercing port 21. The connecting seat 51 has a piercing area 53 larger than the outer diameter of the piercing port 21, and a sealing film 7 is provided on its top. When the upper bottle moves downwards, the piercing port 21 pierces the sealing film 7 and enters the piercing area 53, eventually resting at the bottom of the piercing area 53. The mixed paste or mixed liquid flows from the first cavity 1 through the discharge area 15, the through hole 52, the piercing port 21, and the second cavity 2, before exiting from the discharge nozzle 4.

[0029] In a preferred embodiment, a silicone gasket 6 is provided between the connecting seat 51 and the lower inner bottle 11. The lower outer bottle 12 has a connecting cavity 13, with a connecting step 14 at its upper part. The main body of the lower inner bottle 11 is inserted into the connecting cavity 13. A connecting ring 17 is provided at the bottle opening of the lower inner bottle 11, pressing against the connecting step 14. The silicone gasket 6 presses against the connecting ring 17, with its outer surface abutting against the inner wall of the connecting cavity 13. The bottom of the connecting seat 51 presses against the silicone gasket 6. The silicone gasket 6 connects the connecting seat 51, the lower inner bottle 11, and the lower outer bottle 12 simultaneously, achieving a sealed connection between the three and ensuring the airtightness of the first cavity 1.

[0030] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
