Description

Technical Field

[0001] The utility model relates to a cosmetic container, in particular to a rod-shaped container with a leak-proof structure. Background Art

[0002] Nowadays, makeup has become an essential beauty ritual for women. Wearing makeup is not only a way to show respect for one's appearance but also a way to show respect for others. Paste-based products, such as lipstick, sunscreen sticks, shadow sticks, and concealer sticks, are a crucial part of beauty makeup, allowing for easy application and touch-ups. However, with the advancement of existing stick materials, these materials contain water. During filling or use, this water often leaks out, resulting in leakage and a negative user experience. Summary of the Invention

[0003] The utility model provides a rod-shaped container with a leak-proof structure that can effectively prevent leakage, has a good user experience, and does not affect the use of the cosmetic container due to moisture released from the rod material during filling and use; it solves the technical problem in the prior art that the newly emerged rod material easily releases moisture from the rod container, thus affecting the use effect.

[0004] The above-mentioned technical problem of the present invention is solved by the following technical solution: a rod-shaped container with a leak-proof structure, comprising a base and a cover, a middle ring and a spiral seat provided in the base, a material cup installed in the middle ring, the spiral seat driving the material cup to move axially in the middle ring, at least one layer of annular retaining ring provided on the annular outer surface where the middle ring meets the base, a feed port provided in the center of the material cup, a water absorption tray provided at the bottom end of the feed port, and the water absorption tray located at the bottom of the base. When filling a material with a high water content, filling is performed upward from the feed port in the center of the material cup. After filling, the precipitated water falls from the feed port into the water absorption tray below, thereby completing the water absorption and leakage prevention during filling. During use, if the stick-shaped container is tilted or inverted, the moisture that usually accumulates in the center of the material cup will leak between the middle ring and the base due to the inversion or tilt. After the annular retaining ring is formed outside the middle ring, the retaining ring effectively prevents the leakage of moisture, ensuring that the stick-shaped container can lock the material that overflows the edge even under non-airtight conditions, thereby increasing the sealing stability of the product and the cleanliness of user use.

[0005] Preferably, the spiral seat includes a spiral fixing base, the spiral fixing base is connected to the base, a spiral body is provided above the spiral fixing base, the inner wall of the spiral body is provided with threads, the inner wall of the spiral body is connected to the material cup, and the outer wall of the spiral body is connected to the middle ring. Rotating the spiral seat drives the material cup to move axially within the middle ring.

[0006] Preferably, a sealing ring is provided between the outer wall of the spiral body and the middle ring. The sealing ring is embedded to further seal the leaked water and prevent it from leaking outwards and affecting the user experience.

[0007] Preferably, the cover comprises an inner cover and an outer cover, wherein the inner cover is connected to the cup body and the outer cover is connected to the base. During potting, the inner cover limits the material in the material cup and determines the filling amount in the material cup.

[0008] Preferably, the lower end of the middle ring abuts against the spiral seat, and two layers of retaining rings are provided between the middle ring and the base.

[0009] Preferably, the inner wall of the middle ring is provided with a stop protrusion, the bottom surface of the material cup is located above the stop protrusion, and the bottom end of the material cup is provided with a protruding column protruding outward, which abuts against the bottom of the stop protrusion as the material cup moves, thereby facilitating the axial movement of the material cup.

[0010] Therefore, the rod-shaped container with a leak-proof structure of the utility model has the following advantages: through the design of the retaining ring on the outer wall of the middle ring, the water absorption plate under the material cup, and the design of the sealing ring between the middle ring and the spiral seat, the triple design has a good anti-leakage effect, effectively protects against the water analysis of the new material rod, enhances the product sealing stability and the cleanliness of user use, and improves the overall use experience.

[0016] The technical solution of the utility model is further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example 1:

[0018] like Figure 1 and 2As shown in Figure 3, a rod-shaped container with a leak-proof structure includes a cylindrical base 8, a coaxial spiral seat 6 is installed at the bottom of the base 8, and a thread is formed on the inner wall of the spiral seat 6. A middle ring 4 is also installed in the base 8, and the middle ring 4 is located above the spiral seat 6. The middle ring 4 is annular. A material cup 3 is installed in the middle ring 4, and a water absorption disk 7 is installed below the material cup 3. The water absorption disk 7 is made of a polymer PE sheet. The material cup 3 is fastened with an inner cover 2 above, and an outer cover 1 is provided above the inner cover 2. The outer cover 1 covers the middle ring 4 and is connected to the base 8. The spiral seat 6 includes a spiral fixing base, which is connected to the base 8. A spiral body is provided above the spiral fixing base, and the inner wall of the spiral body is provided with a thread. The inner wall of the spiral body is connected to the material cup 3, and the outer wall of the spiral body is connected to the middle ring 4. A sealing ring 5 is provided between the outer wall of the spiral body and the middle ring 4.

[0019] like Figure 4 As shown, a positioning ring 10 is formed at the bottom and center of the center ring 4, each with an interference fit against the inner wall of the base. Two parallel annular retaining rings 12 are formed between the two positioning rings 10. Two inwardly projecting stop protrusions 11 are formed in the center of the inner wall of the center ring. These stop protrusions 11 are located on the same diameter, and the bottom of the cup 3 is located above these stop protrusions 11.

[0020] like Figure 5 As shown, the material cup 3 includes a material cup body 13, the lower end surface of which abuts against the upper stop protrusion 11 of the middle ring. The material cup body 13 contains a material body 9 with a high water content. Below the material cup body 13 is an integrally formed rotating body 14, the outer circumferential surface of which is provided with a thread, which is connected to the spiral body of the spiral seat 6. A feed port 15 is provided in the center of the rotating body 14, and the filling is performed at the bottom of the feed port 15. A protruding column 16 is formed at the bottom of the feed port 15. When the material cup rises to a certain height, the protruding column 16 abuts against the lower side of the stop protrusion 11 to prevent the material cup 3 from falling out of the middle ring 4.

[0021] During use, the material is filled from the bottom of the feed port. The inner cover is located above the material cup. Once the material cup is filled, the leaking water drips from the feed port into the water absorption tray and is absorbed by the water absorption tray. During use, if the stick-shaped container is inverted or tilted, causing the water to flow back from the feed port, the sealing ring and the retaining ring on the middle ring can prevent leakage, ensuring product cleanliness and improving the user experience.

[0022] The specific embodiments described herein are merely illustrative of the concepts of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
