Description

Technical Field

[0001] This utility model relates to the field of cosmetic pen technology, specifically a sealing structure for the mouth of a lip gloss bottle. Background Technology

[0002] Lip gloss is a popular cosmetic among women. It is generally liquid and has a certain degree of fluidity, so it needs to be stored in a sealed bottle. For ease of use, a brush tip that can be inserted into the bottle is provided inside the cap. To prevent the flowing lip gloss from contaminating the cap, a sealing element with a central hole is provided at the bottle opening. This sealing element can isolate the lip gloss from the cap.

[0003] However, existing lip gloss bottle seals are usually made of a single material of plastic. These seals need to be fastened to the bottle opening to prevent them from falling off. Therefore, seals are often made of relatively hard materials to achieve the above functions. However, more and more women prefer to use hard lip gloss tips, which are also wider. This makes it difficult for ordinary single-material seals to accommodate such wide tips. In addition, the friction generated by such wide tips during insertion and removal is greater, which can easily cause single-material seals to loosen or fall off, resulting in poor sealing and failing to meet the user's needs. Utility Model Content

This solves the problem that existing lip gloss bottle seals typically use a single material, plastic. These seals need to be fastened to the bottle opening to prevent them from falling off, so a relatively hard material is often chosen to achieve this function. However, more and more women prefer to use hard lip gloss tips, which are wider. This makes it difficult for ordinary single-material seals to accommodate these wider tips. Furthermore, the greater friction generated during insertion and removal of these wider tips easily causes the single-material seals to loosen or fall off, resulting in poor sealing and failing to meet user needs.

[0006] The stable sealing assembly includes a sealing plug sleeve inserted into the bottle mouth, an interference fit ring on the outer side of the sealing plug sleeve, a retaining ring at the bottom end of the sealing plug sleeve, a sealing plug head fitted at the bottom end of the sealing plug sleeve, a retaining groove inside the sealing plug head, an annular slot at the top end of the bottle mouth, a top abutment ring at the top end of the bottle mouth, a fixing inner ring at the bottom end of the top abutment ring, and a fixing outer ring fitted on the outer side of the fixing inner ring.

[0007] Preferred technical solution 1: The outer side of the bottle opening is provided with external threads, the inner wall of the bottle cap is provided with internal threads, and the bottle cap and the bottle opening are connected by threads.

[0008] Preferred technical solution 2: The bottom end of the sealing plug is provided with an opening.

[0009] Preferred technical solution 3: The diameter of the interference fit ring is larger than the inner diameter of the bottle mouth.

[0010] This design ensures that when the sealing plug is inserted into the bottle neck, the rubber material of the contact ring achieves an interference fit, making the sealing plug more stable in the bottle neck.

[0011] Preferred technical solution four: The diameter of the fixed inner ring is the same as the inner diameter of the sealing plug sleeve.

[0012] This design allows the inner fixing ring to be inserted into the sealing sleeve, thus fixing the sealing sleeve inside the bottle opening.

[0013] Preferred technical solution five: The inner wall of the annular slot is provided with external threads, the inner wall of the fixed outer ring is provided with internal threads, and the fixed outer ring is inserted into the annular slot and connected by threads.

[0014] This design allows the inner ring to be fixed to the sealing sleeve, while the outer ring can be inserted into the annular slot and threadedly connected to it, thereby fixing the sealing sleeve to the top of the bottle mouth. This makes the sealing sleeve and the bottom-mounted sealing plug more stably positioned inside the bottle mouth.

[0015] Compared with the prior art, this utility model provides a sealing structure for the mouth of a lip gloss bottle, which has the following characteristics:

[0016] Beneficial effects:

[0017] (1) This utility model provides a stable sealing component on the bottle mouth, wherein the end of the sealing sleeve in the stable sealing component is fitted with a sealing plug, which is inserted into the bottle mouth port together. This can effectively scrape off excess lip gloss carried on the pen barrel and pen head that are pulled out of the bottle. The top of the sealing sleeve is also fixed by a top contact ring, a fixing inner ring, and a fixing outer ring, so that the sealing sleeve is inserted into the bottle mouth port more stably. This allows the sealing sleeve and sealing plug to seal the bottle mouth port while effectively preventing the stable sealing component from falling off at the bottle mouth port, thus meeting the user's usage standards.

[0025] Please see Figure 1-5 ,

[0026] Example 1: A lip gloss bottle mouth sealing structure includes a bottle body 1, a bottle mouth 2 at the top of the bottle body 1, a bottle cap 3 on the bottle mouth 2, a pen barrel 4 connected to the bottle cap 3, a pen tip 5 at the bottom of the pen barrel 4, and a stable sealing component 6 on the bottle mouth 2.

[0027] The stable sealing assembly 6 includes a sealing sleeve 601 inserted into the bottle mouth 2. An interference-fit ring 602 is provided on the outer side of the sealing sleeve 601. A retaining ring 603 is provided at the bottom end of the sealing sleeve 601. A sealing plug head 604 is fitted at the bottom end of the sealing sleeve 601. A retaining groove 605 is provided in the sealing plug head 604. An annular slot 606 is provided at the top end of the bottle mouth 2. A top abutment ring 607 is provided at the top end of the bottle mouth 2. A fixing inner ring 608 is provided at the bottom end of the top abutment ring 607. A fixing outer ring 609 is fitted on the outer side of the fixing inner ring 608.

[0028] The bottle mouth 2 has an external thread on its outer side, and the bottle cap 3 has an internal thread on its inner wall. The bottle cap 3 and the bottle mouth 2 are connected by threads.

[0029] The bottom end of the sealing plug 604 is provided with an opening.

[0030] Example 2: The difference between this example and Example 1 is that the diameter of the interference fit ring 602 is larger than the inner diameter of the bottle mouth 2.

[0031] When the sealing sleeve 601 is inserted into the bottle mouth 2, the rubber material of the interference contact ring 602 ensures that the sealing sleeve 601 is inserted into the bottle mouth 2 in an interference fit, thereby making the sealing sleeve 601 inserted into the bottle mouth 2 more stable.

[0032] Example 3: The difference between this example and Example 1 is that the diameter of the fixed inner ring 608 is the same as the inner diameter of the sealing plug sleeve 601.

[0033] This allows the inner ring 608 to be inserted into the sealing sleeve 601, thus fixing the sealing sleeve 601 inside the bottle mouth 2.

[0034] Example 4: The difference between this example and Example 1 is that the inner wall of the annular slot 606 is provided with external threads, the inner wall of the fixing outer ring 609 is provided with internal threads, and the fixing outer ring 609 is inserted into the annular slot 606 and connected by threads.

[0035] After the inner ring 608 fixes the sealing sleeve 601, the outer ring 609 can be inserted into the annular slot 606 and threadedly connected to it, thereby fixing the sealing sleeve 601 to the top of the bottle mouth 2, so that the sealing sleeve 601 and the sealing plug head 604 fitted at the bottom are more stably set inside the bottle mouth 2.

[0036] In this embodiment, since existing lip gloss bottle seals are usually made of a single material of plastic, these seals need to be fastened to the bottle opening to prevent them from falling off. Therefore, seals are often made of a relatively hard material to achieve the above-mentioned functions. However, more and more women prefer to use hard lip gloss tips, which are relatively wide. As a result, ordinary single-material seals cannot be well compatible with such wide tips. Moreover, the friction generated by such wide tips during insertion and removal is relatively large, which can easily cause the single-material seals to loosen or fall off, resulting in poor sealing effect and difficulty in meeting the user's needs.

[0037] In summary, in specific implementation, a stable sealing component 6 is provided on the bottle mouth 2. The bottom of the sealing sleeve 601 in the stable sealing component 6 is fitted with a sealing head 604, which is made of silicone. This allows the pen tip 5, which has a relatively wide opening at the bottom of the sealing head 604, to be pulled out, so that the excess lip gloss on it can be scraped off when it is pulled out, ensuring that the amount of lip gloss adhering to the pen tip 5 is appropriate for the user's usage. A retaining ring 603 is provided at the bottom of the sealing sleeve 601, and a retaining groove 605 is provided in the sealing head 604. Thus, when the sealing head 604 is fitted on the end of the sealing sleeve 601, the retaining ring 603 can be embedded in the retaining groove 605, making the sealing head 604 fit more stably on the sealing sleeve 601.

[0038] The sealing sleeve 601 is also provided with an interference-fit ring 602. The interference-fit ring 602 can be inserted into the end of the bottle mouth 2, thereby making the sealing sleeve 601 more stable when inserted into the top of the bottle mouth 2. By inserting the fixing inner ring 608 at the bottom of the top interference ring 607 on the sealing sleeve 601, the sealing sleeve 601 can be resisted by the sealing sleeve 601 and the inner wall of the bottle mouth 2, and is more stably fixed at the bottle mouth 2 port. The fixing outer ring 609 is inserted into the annular slot 606. The internal thread of the fixing outer ring 609 is threadedly connected to the external thread of the annular slot 606, thereby fixing the sealing sleeve 601 and the sealing plug 604 at the opening of the bottle mouth 2. Thus, the sealing sleeve 601 and the sealing plug 604 can seal the bottle mouth 2 port while effectively preventing the sealing component 6 from falling off at the bottle mouth 2 port, meeting the user's usage standards.
