Abstract
Description
Technical Field
[0001] This application relates to the field of lip gloss bottles, and more particularly to a double-bottle lip gloss bottle. Background Art
[0002] A lip gloss bottle is a container for holding lip gloss, usually featuring small size and portability. The design of lip gloss bottles emphasizes practicality and aesthetics to meet consumers' high-quality requirements for cosmetic packaging.
[0003] Generally speaking, lip gloss bottles are an important part of the cosmetics industry. Their design, manufacturing, and application involve multiple technical fields, aiming to provide consumers with a better and more convenient cosmetic use experience.
[0004] Currently, in related technologies, a lip gloss bottle includes: an inner bottle, a bottle shoulder, an outer bottle, and an end cap. The inner bottle and the bottle shoulder are connected by ultrasonic welding, the outer bottle and the inner bottle are connected by gluing, and the end cap and the bottle shoulder are connected by threading. During installation, first, the bottle shoulder and the inner bottle are connected by ultrasonic welding; then, the outer bottle and the inner bottle are fixed by gluing, thus completing the installation of the inner bottle, the bottle shoulder, and the outer bottle.
[0005] However, first, although ultrasonic welding can ensure the stability of the connection, since the inner bottle and the bottle shoulder are made of PETG material, once the temperature is too high, the connection between the inner bottle and the bottle shoulder is likely to become brittle, resulting in a decrease in connection stability; once the temperature is too low, the airtightness between the inner bottle and the bottle shoulder is poor. Second, during the gluing process, it is easy to affect the connection between the bottle shoulder and the inner bottle; and during the secondary clamping process, secondary contamination is likely to occur, resulting in a low overall yield of the lip gloss bottle. Summary of the Utility Model
[0006] In order to improve the problems existing in the above technologies, this application provides a double-bottle lip gloss bottle.
[0007] This application provides a double-bottle lip gloss bottle, adopting the following technical solution:
[0008] A double-bottle lip gloss bottle includes: an outer bottle, an inner bottle, and a bottle shoulder. The inner bottle is disposed inside the outer bottle, and the inner bottle is fixedly connected to the outer bottle. The inner bottle and the bottle shoulder are integrally injection-molded.
[0009] A demolding hole is penetrated through the inner bottom wall of the inner bottle, and a bottom cover is disposed inside the demolding hole.
[0010] By adopting the above technical solution, the injection molding method is used to replace the ultrasonic welding method, so that the problems of unstable connection and poor airtightness are not likely to occur. Then, ultrasonic welding between the inner bottle and the bottle shoulder is no longer required. At this time, only ultrasonic welding between the inner bottle and the outer bottle is needed, thus reducing the possibility of secondary pollution when the outer bottle and the inner bottle are connected, and improving the overall yield of the lip gloss bottle. After the demolding hole is set, the mold can be demolded from the demolding hole at the bottom of the inner bottle, so that the wall thickness of the inner bottle can be reduced to increase the capacity of the inner bottle to meet the requirements. Finally, the bottom cover is inserted into the inner bottle for shielding.
[0011] Optionally, a first protrusion is provided on the inner wall of the demolding hole, a second protrusion is provided on the bottom cover, and the first protrusion abuts against the second protrusion.
[0012] By adopting the above technical solution, the clamping connection between the first protrusion and the second protrusion not only realizes the positioning between the bottom cover and the inner bottle, but also improves the stability after the bottom cover is inserted.
[0013] Optionally, a third protrusion is provided on the bottom cover, a groove is formed on the inner wall of the demolding hole, and the third protrusion is arranged in the groove.
[0014] By adopting the above technical solution, the third protrusion improves the stability after the bottom cover is inserted on the one hand and plays a sealing role on the other hand, so that the lip gloss is not likely to leak between the bottom cover and the inner bottle.
[0015] Optionally, it further includes: an end cap outer shell, an end cap inner shell and a brush rod. The end cap inner shell is arranged in the end cap outer shell, and the end cap inner shell is threadedly sleeved on the bottle shoulder. One end of the brush rod is fixed in the end cap inner shell and the other end extends into the inner bottle.
[0016] By adopting the above technical solution, by using the method of threadedly connecting the end cap inner shell and the bottle shoulder, the end cap inner shell and the bottle shoulder can be quickly separated, so that it is convenient for users to apply lip gloss with the brush bristles.
[0017] Optionally, it further includes: a pressing cap, and the pressing cap is arranged on the end cap inner shell.
[0018] By adopting the above technical solution, the pressing cap can improve the overall aesthetics of the lip gloss bottle.
[0019] Optionally, a second buckle is provided on the end cap inner shell, a second clamping groove is formed on the pressing cap, and the second buckle is arranged in the second clamping groove.
[0020] By adopting the above technical solution, the second buckle can quickly install and connect or disassemble and separate the pressing cap and the end cap inner shell, so that it is convenient to replace the pressing cap.
[0021] In summary, the present application includes at least one of the following beneficial effects:
[0022] 1. By using the injection molding method to replace the ultrasonic welding method, it is not easy to have unstable connections and poor airtightness. Then, ultrasonic welding is no longer required between the inner bottle and the bottle shoulder. At this time, only ultrasonic welding of the inner bottle and the outer bottle is needed, thereby reducing the possibility of secondary pollution when connecting the outer bottle and the inner bottle, and improving the overall yield of the lip gloss bottle.
[0023] 2. After setting the demolding hole, the mold can be demolded from the demolding hole at the bottom of the inner bottle, which can reduce the wall thickness of the inner bottle to increase the capacity of the inner bottle to meet the requirements. Finally, the bottom cover is inserted into the inner bottle for shielding.
[0024] 3. By using the snap connection of the first protrusion and the second protrusion, not only the positioning between the bottom cover and the inner bottle is realized, but also the stability after the bottom cover is inserted is improved. Description of the Drawings

[0031] The embodiment of the present application provides a double-bottle lip gloss bottle.
[0032] See Figure 1 , Figure 2 and Figure 3, A double-bottle lip gloss bottle includes: an outer bottle 1, an inner bottle 2, a bottle shoulder 9, an end cap outer shell 5, an end cap inner shell 4, a brush rod 6, and a replaceable press cap 8. The inner bottle 2 is disposed inside the outer bottle 1, and the inner bottle 2 and the outer bottle 1 are fixed by ultrasonic welding. The bottle shoulder 9 is integrally injection-molded at the top of the inner bottle 2. The bottle shoulder 9 is hollow and has openings at both ends. The inner diameter of the bottle shoulder 9 gradually decreases from bottom to top, that is, it is in a necked shape. By using the injection-molding method to replace the ultrasonic welding method, it is not easy to have unstable connections and poor airtightness. Then, ultrasonic welding is no longer required between the inner bottle 2 and the bottle shoulder 9. At this time, only the inner bottle 2 and the outer bottle 1 need to be ultrasonically welded, thereby reducing the possibility of secondary pollution when the outer bottle 1 and the inner bottle 2 are connected, and improving the overall yield of the lip gloss bottle.
[0033] See Figure 3 , Further, a demolding hole 21 is penetrated and opened on the inner bottom wall of the inner bottle 2, and a bottom cover 3 is inserted into the demolding hole 21. The original mold demolding method is to eject from the top opening of the bottle shoulder 9. Since the bottle shoulder 9 is in a necked shape, the inner diameter of the inner bottle 2 needs to be consistent with the minimum inner diameter of the bottle shoulder 9 to be demolded, thus affecting the capacity of the inner bottle 2. After the demolding hole 21 is provided, the mold can be demolded from the demolding hole 21 at the bottom of the inner bottle 2, so that the wall thickness of the inner bottle 2 can be reduced to increase the capacity of the inner bottle 2 to meet the requirements. Finally, the bottom cover 3 is inserted into the inner bottle 2 for shielding.
[0034] See Figure 4 , Further, a ring-shaped first protrusion 211 is integrally formed on the inner wall of the demolding hole 21, and a ring-shaped second protrusion 31 is integrally formed on the side wall of the bottom cover 3. The first protrusion 211 and the second protrusion 31 are in mutual contact, and the first protrusion 211 is located below the second protrusion 31. By using the clamping connection between the first protrusion 211 and the second protrusion 31, not only the positioning between the bottom cover 3 and the inner bottle 2 is realized, but also the stability after the bottom cover 3 is inserted is improved.
[0035] See Figure 4 , Further, a ring-shaped third protrusion 32 is integrally formed on the side wall of the bottom cover 3, and the third protrusion 32 is located below the second protrusion 31. A ring-shaped groove 212 is opened on the inner wall of the demolding hole 21, and the third protrusion 32 is disposed in the groove 212. The third protrusion 32 improves the stability after the bottom cover 3 is inserted on the one hand and plays a sealing effect on the other hand, so that the lip gloss is not easy to leak between the bottom cover 3 and the inner bottle 2.
[0036] See Figure 3, the inner end cap 4 is disposed within the outer end cap 5, and the inner end cap 4 is threadedly sleeved on the bottle shoulder 9. One end of the brush rod 6 is fixed within the inner end cap 4, and the other end extends into the inner bottle 2 and is provided with bristles 61. By threading the inner end cap 4 onto the bottle shoulder 9, the inner end cap 4 can be quickly separated from the bottle shoulder 9, facilitating the user to apply lip gloss with the bristles 61.
[0037] See Figure 3 , the pressing cap 8 is sleeved on the top end of the inner end cap 4. In the embodiment of the present application, the pressing cap 8 can be processed into a diamond shape, thereby enhancing the overall aesthetic appearance of the lip gloss bottle.
[0038] See Figure 5 , further, a ring-shaped second buckle 42 is integrally formed on the side wall of the pressing cap 8, and a ring-shaped second slot 81 is formed on the inner side wall of the pressing cap 8. The second buckle 42 is disposed within the second slot 81. The second buckle 42 enables quick installation and connection or disassembly and separation of the pressing cap 8 and the inner end cap 4, facilitating the replacement of pressing caps 8 of different shapes to display different aesthetic appearances and thus attracting customers to purchase the product. In the embodiment of the present application, the materials involved in the snap connection are all flexible, capable of deforming and then quickly recovering.
[0039] The working principle of a double-bottle lip gloss bottle of the present application during use is as follows: After setting the demolding hole 21, the mold can be demolded from the demolding hole 21 at the bottom of the inner bottle 2, thereby reducing the wall thickness of the inner bottle 2 to increase the capacity of the inner bottle 2 to meet the requirements; finally, the bottom cover 3 is inserted into the inner bottle 2 for shielding.
[0040] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
