Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically relating to a dry and wet separation storage bottle. Background Technology

[0002] Freeze-dried powder is highly favored in the beauty and skincare industry due to its high activity, potent efficacy, and low irritation. Freeze-dried powder is produced by dehydrating the active ingredients (in liquid form) in a low-temperature vacuum environment using freeze-drying technology, turning them into a solid powder. This technology maximizes the stability of the active ingredients, which are then activated with a liquid solvent before use.

[0003] Freeze-dried powder is highly hygroscopic and typically needs to be stored in a dry, sealed environment. Because it requires activation with a liquid solvent during use, it must be shipped with a liquid solvent. Currently, both the freeze-dried powder and the liquid solvent are packaged in separate bottles, which increases packaging costs and volume.

[0004] Because freeze-dried powder needs to be isolated from both liquid solvents and external water vapor. Currently available dry-wet separation packaging bottles only consider the isolation between the powder and the solvent, but cannot achieve the isolation from external water vapor. After a period of storage, the freeze-dried powder will absorb moisture from the environment, causing the powder to absorb moisture, clump, and become ineffective. Utility Model Content

[0005] To address at least one of the problems in the prior art, the purpose of this invention is to provide a dry-wet separation storage bottle. A threaded connecting cap seals the freeze-dried powder and liquid solvent within their respective bottles, solving the problem of powder absorbing external moisture. After removing the connecting cap, the powder-liquid bottle and the liquid bottle are directly connected, making operation simple and practical.

This not only achieves the separation of powder and liquid but also ensures isolation from the outside world. It has a simple structure, good sealing performance, and is easy to use.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Example

[0036] Please refer to the reference. Figures 1 to 5 This embodiment provides a dry and wet separation storage bottle, including a liquid bottle 1, a connecting cap 2, and a powder bottle 3;

[0037] The liquid bottle 1 has an opening at the bottom and a first internal thread 101 is provided on the lower inner wall of the liquid bottle;

[0038] The upper outer wall of the connecting cover 2 is provided with a first external thread 201 that can be connected to the first internal thread 101; the lower inner wall of the connecting cover 2 is provided with a second internal thread 202; and a partition 203 is provided in the middle of the connecting cover 2.

[0039] The powder bottle 3 has an opening at the top, and the upper outer wall of the powder bottle 3 is provided with a second external thread 301 that can be connected to the second internal thread 202;

[0040] The second external thread 301 can be connected to the first internal thread 101.

[0041] Specifically, the connecting cap 2 can be made of plastic or metal. The connecting cap 2 connects to the liquid bottle 1 and the powder bottle 3 via threads, acting as a sealing plug to ensure a tight seal after connection. Both the liquid bottle 1 and the powder bottle 3 can be plastic bottles, but the sidewalls at the openings where they connect to the connecting cap 2 can be thickened to ensure their rigidity and elasticity, thus guaranteeing the stability and sealing of the connection between the connecting cap 2 and the liquid bottle 1 and powder bottle 3. The liquid bottle 1 is a flexible plastic bottle, which can be used to squeeze out liquid when pressed; the powder bottle 3 is made of rigid plastic, and its connection to the liquid bottle 1 reinforces the storage bottle.

[0042] Liquid bottle 1 and powder bottle 3 have the same outer diameter. The lyophilized powder is stored in powder bottle 3, and the liquid solvent is stored in liquid bottle 1.

[0043] In this embodiment, the top of the liquid bottle 1 is provided with a bottle mouth, and a sealing film is provided at the bottle mouth. The sealing film can be an aluminum-plastic film, which is pressed onto the bottle mouth by a hot pressing process to seal the bottle mouth.

[0044] In this embodiment, a bottle cap 4 is connected to the bottle mouth, and the bottle cap 4 is threadedly connected to the bottle mouth. The upper part of the bottle cap 4 is a cone, and a liquid outlet is provided at the top of the bottle cap 4.

[0045] In this embodiment, on the inner wall of the liquid bottle 1, a first annular groove 102 is provided at the lower part of the first internal thread 101, and a first annular sealing ring 204 that can be engaged with the first groove 102 is provided at the lower part of the first external thread 201 on the connecting cap 2. On the outer wall of the powder bottle 3, a second annular sealing ring 302 is provided at the lower part of the second external thread 301, and a second annular groove 205 that can engage with the second sealing ring 302 is provided at the lower part of the second internal thread 202 on the connecting cap 2; the second sealing ring 205 can engage with the first groove 102.

[0046] In practical applications, when the connecting cap 2 is screwed into the liquid bottle 1, the first internal thread 101 and the first external thread 201 are screwed together. When both are tightened, the first sealing ring 204 can just fit into the first groove 102. The first sealing ring 204 and the first groove 102 can better achieve the sealing performance between the liquid bottle 1 and the connecting cap 2. When separating the two, under the screwing force of the first internal thread 101 and the first external thread 201, the first sealing ring 204 can disengage from the first groove 102, completing the separation operation between the liquid bottle 1 and the connecting cap 2. Similarly, when the connecting cap 2 is connected to the powder bottle 3, when the second internal thread 202 and the second external thread 301 are tightened, the second sealing ring 302 just fits into the second groove 205, which can better achieve the sealing performance between the connecting cap 2 and the powder bottle 3. When separating the two, under the screwing force of the second internal thread 202 and the second external thread 301, the second groove 205 can disengage from the second sealing ring 302, completing the separation operation between the powder bottle 3 and the connecting cap 2.

[0047] In this embodiment, the cross-sections of the first groove 102 and the second groove 205 are both semi-circular, which facilitates the engagement and disengagement of the corresponding sealing rings. The cross-sections of the first sealing ring 204 and the second sealing ring 302 are circular, and semi-circular sealing ring mounting grooves can be provided at the connection points with the connecting cap 2 and the powder bottle 3. The first sealing ring 204 and the second sealing ring 302 are fixedly installed in their respective mounting grooves, ensuring a secure connection between the first sealing ring 204 and the second sealing ring 302 on the connecting cap 2 and the powder bottle 3. The first sealing ring 204 and the second sealing ring 302 can be rubber rings.

[0048] Please refer to the reference. Figure 6In this embodiment, the dry and wet separation storage bottle contains lyophilized powder stored in powder bottle 3 and liquid solvent stored in liquid bottle 1 at the time of manufacture. Since the connecting cap 2 is connected to liquid bottle 1 and powder bottle 3 by threads, they have good sealing performance and the lyophilized powder can be stored for a long time. When in use, the connecting cap 2 is removed from liquid bottle 1 and powder bottle 3, and then powder bottle 3 and liquid bottle 1 are tightened together by the first internal thread 101 and the second external thread 301. The lyophilized powder and liquid solvent are mixed, the sealing film at the bottle mouth is removed, and the mixed solution is poured out through the liquid outlet of bottle cap 4.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
