Description

Technical Field

[0001] This utility model relates to the field of packaging bottle technology, specifically to a detachable double-layer bottle body. Background Technology

[0002] In the pharmaceutical and cosmetic industries, many products are not limited to one or a few ingredients. However, during daily storage, many products are stored in a single bottle. These products often contain sensitive ingredients, such as drug components, active compounds, plant extracts, and vitamins. These ingredients may be affected by oxidation, light, or contamination, which can reduce their effectiveness or cause quality problems. Therefore, the packaging bottle must be completely sealed. Furthermore, if some ingredients in a product are mixed in advance, they may become ineffective or undergo chemical reactions, resulting in the product not achieving the desired effect when used.

[0003] Therefore, in order to solve the problem that storing all the ingredients of medical aesthetic products in a single chamber will cause some of the ingredients to become ineffective, there is an urgent need for a double-walled bottle that can achieve a sealing effect and is separable. Utility Model Content

[0004] To address the problem mentioned in the background art that storing mixed product components in a single-chamber bottle can lead to the deactivation of some components, this invention proposes a detachable double-layer bottle. The technical solution adopted by this invention is as follows:

[0005] A separable double-layered bottle includes an upper cap for separating and storing some components, a middle cap for fitting together to achieve a sealing effect, and a bottle body for storing the remaining components; the upper cap is movably installed on the upper end of the middle cap, and the bottle body is movably installed on the lower end of the middle cap; the bottom of the middle cap is provided with a communication port for adjusting and connecting the upper cap and the bottle body.

[0006] In one embodiment, the top cover is provided with a semi-enclosed hollow interior. The top cover includes a first locking ring, which is fixedly disposed on the upper end of the outer surface of the top cover. The inner surface of the first locking ring and the outer surface of the top cover form a first limiting groove. The inner surface of the first locking ring in the first limiting groove is provided with a first internal thread, and the outer surface of the top cover in the first limiting groove is provided with a protrusion.

[0007] In one embodiment, the middle cover includes a second locking ring and a locking block. The second locking ring is fixedly disposed on the outer surface of the middle cover, and the locking block is disposed on the top of the outer surface of the middle cover.

[0008] In one embodiment, the inner surface of the second locking ring and the outer surface of the middle cover form a second limiting groove, and the inner surface of the second locking ring in the second limiting groove is provided with a second internal thread.

[0009] In one embodiment, the outer surface of the middle cover at the upper end of the second locking ring is provided with a first external thread, which is disposed between the second locking ring and the locking block.

[0010] In one embodiment, the bottle body is configured to be hollow inside, and a second external thread is provided on the top of the outer surface of the bottle body.

[0011] In one embodiment, the outer surface and top of the cover are provided with a first vertical ridge.

[0012] In one embodiment, the outer surface of the middle cover is provided with second vertical stripes at intervals.

[0013] In one embodiment, a first rotation mark is provided within the first vertical ridge on the top of the cover; the first rotation mark is a clockwise mark.

[0014] In one embodiment, a second rotation mark is provided at the bottom of the outer surface of the middle cover at the interval of the second vertical stripe, and the second rotation mark is a counterclockwise mark.

[0015] The beneficial effects of this utility model's detachable double-layered bottle are as follows:

[0016] 1. By setting a structure at the bottom of the middle cover for adjusting the connection between the top cover and the bottle body, it is possible to separate and seal different components based on the closed connection, and also to manually adjust the connection to connect the top cover and the bottle body to mix the separated components. This solves the problem that traditional sealed bottles can only completely mix and store all components in a single chamber, and some components become ineffective due to premature mixing.

[0017] 2. By setting a protrusion on the outer surface of the upper cover in the first limiting groove and setting a locking block on the top of the middle cover, the top of the middle cover can be embedded in the first limiting groove, and the upper cover and the middle cover are threadedly connected. This structure realizes the effect of using the protrusion to limit the locking block on the top of the middle cover, so that the locking block can only slide in the space of the first limiting groove at the upper end of the protrusion under normal circumstances. This ensures that the upper cover and the middle cover are assembled as a whole, which has the advantages of preventing loss and easy storage. Attached Figure Description

The inner surface of the first locking ring 101 in the first limiting groove 102 is provided with a first internal thread 103, and the outer surface of the upper cover 1 in the first limiting groove 102 is provided with a protrusion.

[0028] In this embodiment, the hollow interior of the upper cover 1 is used to store powdered or liquid medicines or beauty products. The first internal thread 103 of the first limiting groove 102 is used to thread the top of the middle cover 2, and the upper cover 1 and the middle cover 2 are made to fit together through the protrusion, so that the upper cover 1 and the middle cover 2 will not separate even if the threaded connection between the upper cover 1 and the middle cover 2 is broken.

[0029] In one embodiment, the middle cover 2 includes a second locking ring 201 and a locking block 204. The second locking ring 201 is fixedly disposed on the outer surface of the middle cover 2, and the locking block 204 is disposed on the top of the outer surface of the middle cover 2.

[0030] In this embodiment, the second locking ring 201 is used to connect the bottle body 3, and the locking block 204 is used to cooperate with the protrusion in the first limiting groove 102 of the upper cover 1, so that the middle cover 2 and the upper cover 1 are interference fit, ensuring that the upper cover 1 and the middle cover 2 are assembled as one unit under normal circumstances.

[0031] In one embodiment, the inner surface of the second locking ring 201 and the outer surface of the middle cover 2 form a second limiting groove 202, and the inner surface of the second locking ring 201 in the second limiting groove 202 is provided with a second internal thread 203.

[0032] In this embodiment, the second internal thread 203 of the second limiting groove 202 is used to thread-connect the top of the bottle body 3 and to seal the inside of the bottle body 3 through the limiting groove.

[0033] In one embodiment, the outer surface of the middle cover 2 at the upper end of the second locking ring 201 is provided with a first external thread 206, which is disposed between the second locking ring 201 and the locking block 204.

[0034] In this embodiment, the first external thread 206 is used to assemble with the first internal thread 103 of the upper cover 1, and the upper cover 1 and the middle cover 2 are integrated into a single assembly based on the threaded connection.

[0035] In one embodiment, the bottle body 3 is hollow inside, and a second external thread 301 is provided on the top of the outer surface of the bottle body 3.

[0036] In this embodiment, the hollow interior of the bottle body 3 is used to store another part of powdered or liquid medicines or beauty products that need to be stored separately. The second external thread 301 is used to assemble with the second internal thread 203 of the middle cover 2, and the bottle body 3 is fixedly installed on the bottom of the middle cover 2 based on the threaded connection.

[0037] In one embodiment, the outer surface and top of the cover 1 are provided with a first vertical ridge 104.

[0038] In this embodiment, the first vertical ridge 104 is used to increase friction, making it easier to rotate the upper cover 1.

[0039] In one embodiment, the outer surface of the middle cover 2 is provided with second vertical stripes 207 at intervals.

[0040] In this embodiment, the second vertical stripe 207 is used to increase friction, making it easier to rotate the middle cover 2.

[0041] In one embodiment, a first rotation mark 105 is provided in the first vertical ridge 104 at the top of the cover 1; the first rotation mark 105 is a clockwise mark.

[0042] In this embodiment, the first rotation indicator 105, which is set to clockwise, indicates that when the top cover 1 needs to be unscrewed, the top cover 1 can be unscrewed by rotating it clockwise, so that the bottom of the top cover 1 is disassembled from the middle cover 2, thereby allowing the connecting port 205 to connect the top cover 1 and the bottle body 3.

[0043] In one embodiment, a second rotation mark 208 is provided at the bottom of the outer surface of the middle cover 2 at the interval of the second vertical stripe 207, and the second rotation mark 208 is a counterclockwise mark.

[0044] In this embodiment, the second rotation indicator 208, which is set to counterclockwise, indicates that when the bottle body 3 needs to be disassembled, the middle cover 2 can be rotated counterclockwise to separate the bottle body 3 from the middle cover 2.

[0045] The specific usage of the detachable double-layer bottle structure of this utility model is as follows:

[0046] Specific Implementation Example 1: When it is necessary to repackage and store powdered or liquid pharmaceuticals or cosmetic products, firstly, invert the top cover 1 and pour the portion of the product to be separated into the hollow interior of the top cover 1. Then, invert the top of the middle cover 2 and embed it into the first limiting groove 102 of the top cover 1, and press it firmly so that the locking block 204 on the top of the middle cover 2 passes through the protrusion in the first limiting groove 102 and is embedded into the first limiting groove 102, forming an interference fit. At this time, the outer wall of the top cover 1 contacts the inner wall of the hollow interior of the middle cover 2. The top cover 1 is then positioned based on a screw... The upper cover 1 is fully installed with the middle cover 2, and the bottom of the upper cover 1 contacts the bottom of the hollow interior of the middle cover 2. Thus, the bottom of the upper cover 1 completely closes the connecting opening 205. Based on the assembly of the upper cover 1 and the middle cover 2, the product stored in the upper cover 1 is sealed. The remaining product to be stored separately is poured into the bottle body 3, and the top of the bottle body 3 is embedded into the second limiting groove 202 of the integrated middle cover 2. The bottle body 3 is then fixedly installed at the bottom of the middle cover 2 based on the threaded connection, thereby completing the separation and storage of the product.

[0047] Specific Embodiment Two: When it is necessary to fully mix the pre-packaged product before use, rotate the top cover 1 according to the first rotation mark 105. At this time, the top cover 1 moves away from the bottle body 3. When the bottom of the top cover 1 is no longer in contact with the bottom of the middle cover 2, the connecting port 205 at the bottom of the middle cover 2 connects the inner cavity of the top cover 1 with the bottle cavity of the bottle body 3. At this time, the powdered or liquid product pre-packaged in the top cover 1 enters the bottle cavity of the bottle body 3 through the connecting port 205 and mixes with the product in the bottle body 3. After the product is completely mixed in the bottle body 3, rotate the middle cover 2 according to the second rotation mark 208 to disassemble the bottle body 3, thereby using the product in the bottle body 3.

[0048] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
