Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, specifically to a one-time injection molded thick-walled lip gloss tube. Background Technology

[0002] The lip gloss tube mainly contains lip gloss, a daily cosmetic product that is easy to apply to the lips and is loved by young people. It can change the lip color and enhance beauty. However, existing lip glosses still have certain defects in use. When used frequently or improperly, the cap and tube body are prone to loosening or wear, resulting in a decrease in the seal between the cap and tube body, leakage of the lip gloss, and waste.

[0003] Patent CN216701902U discloses a highly airtight lip gloss tube. By optimizing the sealing performance of existing makeup tubes and adding a sealing component, it can achieve a sealing effect on the inner wall of the tube for taking out and putting in, preventing the liquid lipstick inside the tube from being exposed, increasing safety during carrying, and effectively improving the sealing performance between the cap and the tube body.

[0004] In the aforementioned patent, the lip gloss tube solves the problems mentioned above. However, the lip gloss tube still has the following problems: most of the lip gloss tubes in the patent, including those currently on the market, are thin-walled products with limited pressure resistance. They are easily damaged when subjected to accidental squeezing or dropping. Thicker-walled lip gloss tubes, due to the characteristics of their internal structure, require secondary injection molding. This process prolongs the production time of a single lip gloss tube, reduces the production efficiency of the lip gloss tube, and increases the production cost for manufacturers due to the long production cycle. This is not conducive to large-scale production and market promotion in factories.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing thick-walled lip gloss tube structure. Utility Model Content

[0006] The purpose of this invention is to provide a one-time injection molded thick-walled lip gloss tube, which solves the problem mentioned in the background art that most existing lip gloss tubes are thin-walled products with limited pressure resistance and are easily damaged when subjected to accidental squeezing or dropping. Thick-walled lip gloss tubes, due to the characteristics of their internal structure, require secondary injection molding, which prolongs the production time of a single lip gloss tube, reduces the production efficiency of lip gloss tubes, and increases the production cost for manufacturers due to the long production cycle, which is not conducive to large-scale production and market promotion.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a one-time injection molded thick-walled lip gloss tube, comprising a tube body, a lip gloss head, and a lip gloss cap;

The upper end of the lip gloss cap is fitted into the snap-lock cap to close the upper end of the snap-lock cap. Rotating the lip gloss cap can separate it from the tube body for easy use of the lip gloss. The special structural design of the lip gloss tip can more accurately control the amount of lip gloss applied, avoiding lip gloss waste. The snap-lock cap design can also effectively prevent the lip gloss from spilling during carrying, ensuring the hygiene and safety of the product.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the parts of this utility model are made by one-time injection molding, which shortens the production cycle and saves production costs; the structure is reasonably designed, the tube body adopts a thick bottom and thick wall design, and the opening is equipped with a sealing sleeve to prevent waste, which is not easy to be damaged and has a long service life; the installation structure is simple, the lip gloss cap and the lip gloss rod are connected by a connecting buckle, the cap is snapped into the top of the lip gloss cap, and the lip gloss cap and the tube body are connected by threads, which improves production efficiency.

[0014] 1. The one-time injection molded thick-walled lip gloss tube has also been optimized in terms of material selection, using high-strength and corrosion-resistant plastic material to ensure that the lip gloss tube will not be damaged by corrosion of lip gloss during long-term use, while also improving the overall texture of the product.

[0015] 2. Furthermore, the design of the structural material has good processing performance, which facilitates one-time injection molding, further reducing production costs. In addition, during the production process, it is convenient to ensure the pass rate of production by precisely controlling the injection molding process parameters.

[0016] 3. Furthermore, the lip gloss cap can be rotated to separate it from the tube, making it easy to dispense the lip gloss. The special structure of the lip gloss applicator allows for more precise control of the amount of lip gloss applied, avoiding waste. The snap-lock cap design also effectively prevents the lip gloss from spilling during transport, ensuring the hygiene and safety of the product. Attached Figure Description

[0025] In a specific embodiment, this utility model provides the following technical solution: a one-time injection molded thick-walled lip gloss tube, such as... Figures 1-6 As shown;

[0026] The tube body 1, lip gloss head 2, and lip gloss cap 3 are provided. The tube body 1 has an opening at the upper end, and a sealing sleeve 101 is installed at the opening. The outer wall of the opening has an external threaded protrusion 102. The lip gloss head 2 is inserted into the inner wall of the tube body 1 through the opening. The lip gloss head 2 is installed at the front end of the lip gloss rod 201. The lip gloss rod 201 is the connecting rod between the lip gloss head 2 and the lip gloss cap 3. The rear end of the lip gloss rod 201 is connected to the lip gloss cap 3 with a snap-fit. The lower end of the lip gloss cap 3 has an internal thread 301, which is sleeved with the internal thread 301 of the external threaded protrusion 102 at the upper end of the tube body 1.

[0027] Furthermore, the tube body 1 is a thick-walled tube with a bottom thickness of 10mm and a wall thickness of 4mm. It is injection molded in one piece, making it sturdy and durable. The bottom is also provided with a recessed groove 104 with a depth of 1mm, which can slightly cope with uneven tabletops or floors and facilitates placement.

[0028] Furthermore, a sealing sleeve 101 is installed at the opening at the upper end of the tube body 1. The sealing sleeve 101 has through holes at the top and bottom, with a larger upper opening and a smaller lower opening to prevent the lip gloss from flowing out of the inner wall. Below the sealing sleeve 101 is a lip gloss capacity groove 103 to store the lip gloss. When the front end of the lip gloss head 2 passes through the sealing sleeve 101, the excess lip gloss will be scraped off by the lower opening of the sealing sleeve 101.

[0029] Furthermore, the inner wall of the lip gloss cap 3 is provided with a groove 302, which matches the connecting buckle 202 at the rear end of the lip gloss rod 201 and forms a connecting buckle connection.

[0030] Furthermore, the lip gloss cap 3 is a sleeve with upper and lower through holes and a wall thickness of 1.5mm. It is injection molded in one piece. The inner wall of its lower end is provided with an internal thread 301 for threaded connection to the tube body 1. The upper part of the internal thread 301 is connected to the lip gloss rod 201 with a buckle. The upper end of the lip gloss cap 3 is fitted into the snap-lock cap 303 to close.

[0031] Working principle: By rotating the lip gloss cap 3 to separate it from the tube body 1, the lip gloss tip 2 is exposed. The user can lightly touch the lip gloss tip 2 to the lips for application. Since the lip gloss tip passes through the sealing sleeve 101, the lower opening of the sealing sleeve 101 will automatically scrape off the excess lip gloss, so the amount of lip gloss taken out each time is more accurate, which can effectively avoid waste. After application, align the lip gloss cap 3 with the external threaded protrusion 102 of the tube body, rotate the lip gloss cap 3 to make it tightly connected to the tube body 1 through the threaded structure, and finally put the locking cap 303 into the upper port of the lip gloss cap 3 to close it. This can effectively prevent the lip gloss from spilling during carrying, ensuring the hygiene and safety of the product, thus completing the use of the lip gloss tube, effectively improving the convenience of use of the lip gloss tube and increasing its overall practicality.
