Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging container technology, specifically a lip gloss bottle with good sealing properties. Background Technology

[0002] Lip gloss is a viscous liquid or thin, creamy lip cosmetic, rich in highly moisturizing oils and shimmering agents. Due to its properties, lip gloss requires well-sealed packaging to prevent evaporation, drying, or leakage. Existing lip gloss bottles typically consist of a bottle body and cap connected by threads or snap-fit ​​mechanisms, which have the following drawbacks:

[0003] Insufficient sealing: Traditional threaded connections are prone to loose fit due to processing errors or wear, resulting in tiny gaps between the cap and the bottle body, causing the lip gloss liquid to evaporate or leak.

[0004] Lip gloss waste: When the brush is removed from the bottle, it usually has too much lip gloss on it, which can easily drip onto the outside, causing waste and contamination.

[0005] Therefore, there is an urgent need for a lip gloss bottle with a reasonable structure, excellent sealing performance, and easy use, which can effectively solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a lip gloss bottle with good sealing performance.

[0007] To solve the above problems, the technical solution of this utility model is as follows: a lip gloss bottle with good sealing performance, including a bottle body and a bottle cap, wherein an inner plug is provided at the bottle mouth of the bottle body, the inner plug is funnel-shaped and has a constricted part at the bottom, a brush rod is provided inside the bottle cap, and a brush head is installed at the end of the brush rod, the bottle cap includes an outer cap and an inner cap, and a sealing ring is provided between the inner cap and the inner plug.

[0008] Furthermore, the bottle body has an external thread on the outer side of the bottle opening, and the inner cap has an internal thread that mates with the external thread on the inner side.

[0009] Furthermore, the inner plug has a positioning ring at the top of the bottle mouth, a constricted opening at the bottom, and multiple outwardly protruding annular ribs on the side.

[0010] Furthermore, the inner plug is made of silicone, and the inner diameter of its constricted portion is adapted to the diameter of the brush head. The inner side of the bottle mouth is provided with an annular groove adapted to the annular rib.

[0011] Furthermore, the bottom of the sealing ring is provided with a sealing ring that engages with the inner side of the positioning ring.

[0012] Furthermore, the brush head is made of silicone material with a surface densely covered with short bristles.

[0013] The advantages of this utility model compared with the existing technology are as follows: When using the brush head, the closed part of the inner stopper of this utility model will scrape off the excess lip gloss liquid on the brush head to avoid waste; the setting of the inner 3 and the sealing ring can effectively improve the sealing performance of the bottle body and the bottle cap, making it highly practical.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, a lip gloss bottle with good sealing performance includes a bottle body 1 and a bottle cap 2. The bottle cap 2 includes an outer cap 2.1 and an inner cap 2.2. The inner cap 2.2 is glued and fixed to the inside of the outer cap 2.1. The bottle body 1 has an external thread on the outside of the bottle opening, and the inner cap 2.2 has an internal thread that mates with the external thread on the inside.

[0020] A preliminary seal is achieved by the internal thread of the inner cap 2.2 engaging with the external thread of the bottle mouth.

[0021] The bottle body 1 has an inner plug 3 at the bottle mouth. The inner plug 3 is funnel-shaped and has a constricted opening at the bottom. The bottle cap 2 has a brush rod 4 inside, and a brush head 5 is installed at the end of the brush rod 4. The inner plug 3 has a positioning ring 3.1 at the top of the bottle mouth and a constricted opening 3.2 at the bottom. The side has multiple outwardly protruding annular ribs 3.3. The inner plug 3 is made of silicone, and the inner diameter of its constricted opening 3.2 is matched with the diameter of the brush head 5. The inner side of the bottle mouth of the bottle body 1 has an annular groove that matches the annular ribs 3.3. The brush head 5 is made of silicone and its surface is densely covered with short bristles.

[0022] The cooperation between the annular rib 3.3 and the annular groove can improve the sealing of the connection between the inner plug 3 and the bottle body 1, and at the same time improve the stability of the inner plug installation.

[0023] A sealing ring 6 is provided between the inner cover 2.2 and the inner plug 3. The bottom of the sealing ring 6 is provided with a sealing ring that engages with the inner side of the positioning ring 3.1.

[0024] The sealing ring 6 can improve the sealing performance of the connection between the bottle body 1, the cap 2 and the inner plug 3.

[0025] In actual use, when the user opens the bottle cap 2 and uses the brush head 5, the brush handle 4 is pulled out from the inner plug 3. The constricted part 3.2 of the inner plug 3 will scrape off excess lip gloss on the brush head 5 to avoid waste. The inner plug 3 and the sealing ring 6 can effectively improve the sealing of the bottle body 1 and the bottle cap 2.
