Description

Technical Field

[0001] This invention relates to the field of cosmetics technology, and in particular to a novel press-type stirring lip gloss packaging material. Background Technology

[0002] Lip gloss, a popular cosmetic, typically falls between lipstick and lip shimmer in texture, offering both color payoff and shine. However, lip gloss formulas generally contain pigments, oils, and powders. Due to differences in density, these components are prone to separation of the oil and pigment phases, as well as pigment sedimentation, during storage. This results in product layering and uneven color, often referred to as the "glutinous rice ball color" problem. This not only affects the product's appearance but also compromises the user experience and makeup effect. Currently, several packaging solutions exist to address these issues, such as traditional spatula-type lip gloss packaging and packaging with built-in individual stirring balls. The existing technologies suffer from the following problems: Traditional scraper-style lip gloss packaging is the most common type. It uses a scraper attached to the brush handle to scrape off excess product from the nozzle when the brush is pulled out. However, this design is completely incapable of handling the issue of internal layering within the bottle. Consumers need to manually mix the product by shaking the bottle vigorously before use. However, this method has limited mixing effect and easily shakes the product into the bottle opening and inside the cap, causing contamination and waste. In addition, vigorous shaking can introduce air bubbles, affecting the smoothness of subsequent makeup application and the final makeup effect. Some products have adopted a solution similar to nail polish, placing a metal or glass stirring ball inside the bottle. Users mix the product by shaking the bottle and using the impact of the stirring ball. While this solution has some effect, its mixing efficiency depends on the user's shaking force and frequency, making the effect inconsistent. In addition, the noise and impact generated by the stirring ball inside the bottle reduce the user experience, and long-term impact may cause wear and tear on the inner wall of the packaging material.

[0003] In summary, existing lip gloss packaging materials either fail to effectively and conveniently solve the problem of lip gloss layering, or are difficult to popularize due to their complex structure and high cost. Therefore, there is an urgent need in this field for a novel packaging solution that is simple in structure, easy to operate, low in cost, and can efficiently and persistently maintain the uniformity of lip gloss. Summary of the Invention

[0004] The main objective of this invention is to provide a novel press-type stirring lip gloss packaging material, which can effectively solve the problems of existing lip gloss packaging materials that cannot conveniently and efficiently prevent and improve the separation of the paste, and that are inconvenient to use, easy to contaminate, noisy, or have complex structures and high costs.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A novel press-type stirring lip gloss packaging material includes a bottle with an outer cap on top. A button cap extending through the top of the outer cap is located within the inner cavity of the bottle. A rubber spring is located within the inner cavity of the bottle, and a snap-fit ​​sleeve is fixedly installed on the top of the rubber spring. A cross-shaped through hole extending to the inner side of the rubber spring is formed at the bottom of the inner cavity of the snap-fit ​​sleeve. A brush rod is fixedly installed within the inner cavity of the button cap, and an iron spring is fitted onto the outer wall of the brush rod. An inner cap is fixedly installed at the bottom of the inner ring of the outer cap, with the bottom of the iron spring fitting against the top of the inner cap. A rubber pad is snapped onto the top of the inner cavity of the inner cap. An inner plug is fixedly fitted onto the outer wall of the brush rod, located below the rubber pad. When the brush rod is pressed down, the inner plug engages with the inner cavity of the snap-fit ​​sleeve and compresses the rubber spring.

[0006] Preferably, the bottom end of the brush rod passes through the rubber pad and the inner cover to the bottom of the outer cover and is fixedly installed with a brush head.

[0007] Preferably, the bottle has a threaded wall on its side wall, and the inner cap is threadedly connected to the threaded wall of the bottle. After the threaded connection, the brush head passes through the cross-shaped through hole to the inside of the rubber spring.

[0008] Preferably, the bottom of the rubber spring is fixedly connected to the bottom of the inner cavity of the bottle, and the rubber spring is made of elastic rubber or silicone material.

[0009] Preferably, the diameter of the cross-shaped through hole is smaller than the outer diameter of the inner plug, thereby preventing the inner plug from passing through the cross-shaped through hole and allowing only the brush rod and brush head to pass through.

[0010] Preferably, the inner plug is made of a flexible sealing material that deforms to form a seal when the inner plug is inserted into the snap-fit ​​sleeve.

[0011] Preferably, the iron spring is always in a compressed state, thereby applying an upward restoring force to the brush rod, and the upper end of the iron spring contacts the top of the inner cavity of the button cap.

[0012] Preferably, the outer cap completely covers the threaded connection between the inner cap and the bottle, forming a dustproof and leak-proof seal.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a novel press-type stirring lip gloss packaging material, which can achieve instant stirring of the lip gloss through a simple pressing operation, effectively solving the problems of layering and pigment sedimentation caused by the static setting of traditional lip glosses, and improving the user experience and makeup effect. This invention provides a novel press-type stirring lip gloss packaging material. Through the sealing fit between the inner plug and the snap-fit ​​sleeve, the elastic deformation of the rubber spring, and the restoring action of the iron spring, efficient stirring is achieved while ensuring the sealing and leak-proof performance of the packaging material, avoiding contamination and waste of the paste. Moreover, the structure is stable and reliable, low in cost, and easy to promote. This invention provides a novel press-type stirring lip gloss packaging material that uses a flexible rubber spring to replace the traditional metal stirring ball. While achieving efficient and gentle stirring, it completely eliminates the noise and wear on the inner wall caused by the impact of the stirring ball, thereby improving the product's durability and quiet operation.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5As shown, this invention provides a novel press-type stirring lip gloss packaging material, including a bottle 9. An outer cap 2 is disposed on the top of the bottle 9. A button cap 1, penetrating the top of the outer cap 2, is disposed within the inner cavity of the outer cap 2. A brush rod 3 is fixedly installed within the inner cavity of the button cap 1. An iron spring 4 is sleeved on the outer wall of the brush rod 3. The iron spring 4 is pre-compressed between the inner cap 6 and the button cap 1 during assembly. The pre-compression amount is 30% to 50% of the spring's free length, ensuring that the brush rod 3 and the inner plug 7 are always in the upper limit position when not pressed, preventing accidental contact and leakage of the lip gloss. An inner cap 6 is fixedly installed at the bottom of the inner ring of the outer cap 2. The bottom of the iron spring 4 fits against the top of the inner cap 6. A rubber gasket 5 is snapped into the top of the inner cavity of the inner cap 6. An inner plug 7 is fixedly sleeved on the outer wall of the brush rod 3. The inner plug 7 is located... Below the rubber pad 5, a rubber spring 8 is provided in the inner cavity of the bottle 9. A snap-fit ​​sleeve 81 is fixedly installed on the top of the rubber spring 8. A cross-shaped through hole 82 is opened at the bottom of the inner cavity of the snap-fit ​​sleeve 81, which extends to the inner side of the rubber spring 8. The bottom end of the brush rod 3 passes through the rubber pad 5 and the inner cover 6 to the bottom of the outer cover 2 and is fixedly installed with a brush head 31. A threaded wall is opened on the upper side wall of the bottle 9. The inner cover 6 is threadedly connected to the threaded wall of the bottle 9. After the threaded connection, the brush head 31 passes through the cross-shaped through hole 82 to the inner side of the rubber spring 8. When the brush head 31 is not in use, it is located at the bottom of the inner cavity of the rubber spring 8 and does not contact the inner wall of the rubber spring 8. When the user presses the button cap 1 to release it, the brush head 31 rises with the brush rod 3 and brings out an appropriate amount of evenly mixed paste for direct use. The total diameter of the cross-shaped through hole 82 is slightly larger than the diameter of the brush rod 3 but much smaller than the outer diameter of the inner plug 7. Its function is not only to restrict the passage of the inner plug 7, but also to guide the paste to form multiple fine streams during the pressing process, thereby enhancing the shearing and mixing effect. The bottom of the rubber spring 8 is fixedly connected to the bottom of the inner cavity of the bottle 9. The rubber spring 8 is made of elastic rubber or silicone material, which has excellent elasticity and corrosion resistance. The diameter of the cross-shaped through hole 82 is smaller than the outer diameter of the inner plug 7, thereby preventing the inner plug 7 from passing through the cross-shaped through hole 82, and only allowing the brush rod 3 and brush head 31 to pass through. The inner plug 7 is made of flexible sealing material (such as silicone or rubber) and has a conical or frustum-shaped structure. Its outer diameter is slightly larger than the inner diameter of the snap sleeve 81, forming an interference fit. When the inner plug 7 is snapped into the snap sleeve 81, it is squeezed and expands radially, tightly fitting against the inner wall of the snap sleeve 81 to form a one-way seal and prevent the paste from flowing back. The iron spring 4 is always in a compressed state, thereby applying an upward restoring force to the brush rod 3. The upper end of the iron spring 4 contacts the top of the inner cavity of the button cap 1. The outer cover 2 completely covers the threaded connection between the inner cover 6 and the bottle 9, forming a dustproof and leak-proof seal. The rubber spring 8 has a corrugated tubular structure with multiple axially expandable pleats on its sidewalls. The pleats contract when compressed and return to their original shape when released, thereby forming a reciprocating flow channel for the paste inside the rubber spring 8. The rubber spring 8 is made of food-grade silicone to ensure that it has good elastic recovery ability and resistance to cosmetic corrosion. During assembly, first, fix the rubber spring 8 to the bottom of the inner cavity of the bottle 9. Then, install the brush head 31 at the bottom of the brush rod 3. Next, put the iron spring 4 on the brush rod 3 and fix the inner plug 7 on the brush rod 3. Then, fix the top of the brush rod 3 to the inner cavity of the button cap 1, so that the upper end of the iron spring 4 contacts the top of the inner cavity of the button cap 1. Then, snap the rubber pad 5 into the top of the inner cavity of the inner cover 6 and pass the brush rod 3 through the rubber pad 5 and the inner cover 6, so that the bottom of the iron spring 4 fits with the top of the inner cover 6. Finally, thread the inner cover 6 to the threaded wall of the bottle 9 to ensure that the brush head 31 passes through the cross-shaped through hole 82 and enters the inner side of the rubber spring 8. Then, put on the outer cover 2 to complete the assembly.

[0018] The working principle of this new press-type stirring lip gloss packaging material will be explained in detail below.

[0019] like Figure 1-5 As shown, when the user presses the button cap 1, the button cap 1 moves the brush rod 3 downwards, and the inner plug 7 on the brush rod 3 descends and engages with the inner cavity of the snap-fit ​​sleeve 81. During engagement, the inner plug 7 deforms, forming a tight seal with the inner wall of the snap-fit ​​sleeve 81. Simultaneously, it compresses the rubber spring 8, causing it to deform. The lip gloss inside is forced through the gap between the cross-shaped through-hole 82 and the side wall of the rubber spring 8, generating turbulence and shear force, thus achieving efficient mixing and preventing the separation of pigment and oil phases. After releasing the button cap 1, the restoring force of the iron spring 4 pushes the brush rod 3 upwards, causing the inner plug 7 to exit from the snap-fit ​​sleeve 81. The rubber spring 8 returns to its original shape. During this process, the inner plug 7 and the rubber pad 5 cooperate to form a seal, preventing lip gloss leakage. The brush head 31 remains inside the rubber spring 8, making it convenient for the user to take the evenly mixed paste. This invention achieves instant mixing of lip gloss through a simple pressing operation. It has a simple structure, is easy to operate, effectively solves the layering problem, and improves the user experience.
