Description

Technical Field

[0001] This application relates to the field of cosmetics, and particularly to a cosmetic container. Background Art

[0002] Cosmetic containers are widely used items in daily life for storing various cosmetics such as lotions, foundations, etc. However, traditional cosmetic containers have relatively single functions and usually only have a storage function, unable to meet other needs of users during use.

[0003] Especially when users need to stir the cosmetics evenly, the traditional method usually requires pouring the cosmetics into another container and using external tools for stirring. This operation method is not only cumbersome but also easily leads to waste of cosmetics and contamination of the container, bringing a lot of inconvenience to users.

[0004] Therefore, how to design a cosmetic container that can both store cosmetics and facilitate stirring has become an urgent problem to be solved in the current field of cosmetic packaging technology. Content of the Utility Model

[0005] In order to improve the convenience of using cosmetics, this application provides a cosmetic container.

[0006] The cosmetic container provided by this application adopts the following technical solution:

[0007] A cosmetic container includes a bottle body and a cap body. The cap body is used to cover the bottle body. A cylinder is arranged inside the bottle body. The diameter of the cylinder is smaller than the inner diameter of the bottle body, and a reflux channel is formed between the cylinder and the bottle body. Both ends of the cylinder are open. A first isolation part and a second isolation part are arranged inside the cylinder, and a cavity is formed between the first isolation part and the second isolation part. Reflux holes are formed on the cylinder, and both reflux holes communicate with the cavity. A ventilation hole is formed on the first isolation part. A plug rod is fixedly arranged on the cap body. A first insertion hole is formed on the first isolation part, and a second insertion hole is formed on the second isolation part. When the cap body covers the bottle body, the plug rod sequentially passes through the reflux holes and the ventilation hole, and the plug rod has a sliding fit with the reflux holes and a sliding fit with the ventilation hole.

[0008] By adopting the above technical solution, inside the cosmetic bottle, the cylinder and the reflux channel are filled with cosmetics, while the cavity is connected to the atmosphere through the air holes, allowing gas to flow freely; when the cover begins to close, the insertion rod first enters the first insertion hole, and then continues to penetrate into the second insertion hole; in this process, the insertion rod is slidably matched with the reflux hole and the air hole, gradually compressing the space inside the cylinder, pushing the cosmetics to flow in the cylinder and the reflux channel, and realizing automatic stirring of the cosmetics; at the same time, the gas in the cavity flows back to the atmosphere smoothly through the air holes, ensuring internal pressure balance; the stirred cosmetics flow into the cavity through the reflux hole, at which time the insertion rod has been fully inserted, forming an effective blockage for the cavity, ensuring that the evenly stirred cosmetics are safely stored in the cavity; this design not only improves the uniformity of the cosmetics, but also facilitates subsequent use; when applying makeup, removing the cover will drive the insertion rod to be pulled out of the second insertion hole. When the end of the plug rod is pulled out, the cosmetic pieces stored in the cavity are taken out and used directly for makeup, which significantly improves the convenience of use and the makeup effect; at the same time, the liquid cosmetics that may remain in the cavity naturally flow back into the bottle through the second plug hole, which also promotes further mixing of the cosmetics and maintains its uniform texture. This design not only simplifies the process of mixing and taking cosmetics, but also avoids the possible external pollution caused by traditional methods, and improves the hygiene and convenience of use.

[0009] Optionally, the cylinder body includes a first mounting cylinder and a second mounting cylinder, both ends of the first mounting cylinder are open, and both ends of the second mounting cylinder are open; one end of the first mounting cylinder is detachably connected to the bottle mouth of the bottle body, and the other end of the first mounting cylinder is detachably connected to one end of the second mounting cylinder; the first isolation portion is arranged in the first mounting cylinder, and the second isolation portion is arranged in the second mounting cylinder.

[0010] By adopting the above technical solution, since the first mounting cylinder and the second mounting cylinder are detachably connected, the convenience of users in installing and disassembling the cylinder is increased, making the assembly and disassembly of the entire cylinder more convenient and also convenient for cleaning the interior.

[0011] Optionally, a plurality of protrusions are provided at one end of the second mounting tube close to the bottom of the bottle body, and a reflux groove is formed between two adjacent protrusions.

[0012] By adopting the above technical solution, the reflux channel can be interconnected with the interior of the second mounting tube through these reflux grooves, so that the cosmetics can smoothly flow from the second mounting tube into the reflux channel, and then flow back into the cavity through the reflux hole, thereby improving the stirring efficiency.

[0013] Optionally, an installation hole is formed at the end of the first installation cylinder, and an annular groove is formed on the inner side wall of the installation hole; an annular flange is provided on the outer side wall of the end of the second installation cylinder; when the end of the second installation cylinder is inserted into the installation hole, the annular flange is located in the annular groove.

[0014] By adopting the above technical solution, the installation hole positions the second installation cylinder, improving the efficiency of the user in installing and disassembling the cylinder body; when the end of the second installation cylinder is inserted into the installation hole, the annular flange will be exactly located in the annular groove, thus forming a stable plug-in fit relationship.

[0015] Optionally, the first isolation part and the second isolation part are in the shape of a hemispherical shell or an inferior spherical shell or a superior spherical shell.

[0016] By adopting the above technical solution, such a shape is not only beautiful and generous, but also has the functions of storing and stirring liquid cosmetics, making them more uniform.

[0017] Optionally, a plurality of bumps are provided at the end of the second installation cylinder, and a return flow groove is formed between adjacent bumps, and the return flow channel is communicated with the inside of the second installation cylinder through the return flow groove.

[0018] By adopting the above technical solution, the return flow channel can be communicated with the inside of the second installation cylinder through these return flow grooves, enabling the cosmetics to flow smoothly from the second installation cylinder into the return flow channel and then back to the cavity through the return flow holes, thereby improving the stirring efficiency.

[0019] Optionally, an elastic applicator head is detachably connected to the end of the insertion rod. The elastic applicator head can undergo elastic deformation. The elastic applicator head is in sliding fit with the first insertion hole and in sliding fit with the second insertion hole.

[0020] By adopting the above technical solution, when the cover body is closed, the insertion rod and the elastic applicator head at its end enter the first insertion hole and the second insertion hole in turn. The elastic applicator head undergoes elastic deformation during this process, which helps the insertion rod to pass through the holes more smoothly while reducing friction resistance. As the insertion rod goes deeper, the cosmetics are pushed to flow in the barrel and the reflux channel, achieving automatic stirring. When the elastic applicator head contacts the liquid cosmetics, it further promotes the uniform mixing of the cosmetics by using its adsorption property; the uniformly stirred cosmetics flow into the cavity through the reflux hole, and after the insertion of the rod and the elastic applicator head, the cavity is sealed to ensure the safe and hygienic storage of the cosmetics; before applying makeup, the rod and its elastic applicator head are pulled out from the second insertion hole while the cover is opened; the elastic applicator head uses its adsorption property to not only bring out the cosmetic sheets stored in the cavity, but also ensure that these cosmetic sheets maintain a certain degree of moisture and uniformity when they are taken out, directly improving the makeup effect; if a small amount of liquid cosmetics remains in the cavity, it will also be brought out together with the rod when it is pulled out through the adsorption effect of the elastic applicator head, or naturally flow back to the inside of the bottle through the air vent, further maintaining the uniform state of the cosmetics; the design of the elastic applicator head not only optimizes the insertion process of the rod, but also enhances the stirring, storage and use effects of the cosmetics; it not only improves the uniformity and ease of use of the cosmetics, but also reduces the risk of external contamination, bringing users a more efficient and hygienic makeup experience.

[0021] Optionally, the diameter of the elastic application head is greater than the diameter of the insertion rod.

[0022] By adopting the above technical solution, the sealing between the insertion rod and the insertion hole can be further increased, effectively preventing the cosmetics from leaking out of the insertion hole.

[0023] Optionally, a mounting rod is fixedly provided at the end of the elastic applicator head, a mounting hole is opened at the end of the insertion rod, and the mounting rod is plugged into and matched with the mounting hole.

[0024] By adopting the above technical solution, not only the convenience of users in installing and removing the installation rod is increased, but also the connection stability between the elastic applicator head and the insertion rod is enhanced.

[0025] A cosmetic container also includes an outer cover, which is detachably connected to the bottle body; when the outer cover is covered on the bottle body, the cover body is located inside the outer cover.

[0026] By adopting the above technical solution, the outer cover has a protective effect on the cover body, thereby increasing the cleanliness of the cover body surface.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. In the cosmetic bottle, the cylinder and the reflux channel are filled with cosmetics, and the cavity is connected to the atmosphere through the air holes, allowing gas to flow freely; when the cover begins to close, the insertion rod first enters the first insertion hole, and then continues to penetrate into the second insertion hole; in this process, the insertion rod is slidably matched with the reflux hole and the air hole, gradually compressing the space in the cylinder, pushing the cosmetics to flow in the cylinder and the reflux channel, and realizing automatic stirring of the cosmetics; at the same time, the gas in the cavity flows back to the atmosphere smoothly through the air holes to ensure internal pressure balance; the stirred cosmetics flow into the cavity through the reflux hole, and the insertion rod has been fully inserted at this time, forming an effective blockage for the cavity, ensuring that the evenly stirred cosmetics are safely stored in the cavity; this design not only improves the uniformity of the cosmetics, but also facilitates subsequent use; when applying makeup, removing the cover will drive the insertion rod to be pulled out of the second insertion hole. When the end of the plug rod is pulled out, the cosmetic pieces stored in the cavity will be taken out and used directly for makeup, which significantly improves the convenience of use and the makeup effect; at the same time, the liquid cosmetics that may remain in the cavity will naturally flow back into the bottle through the second plug hole, which also promotes further mixing of the cosmetics and maintains its uniform texture. This design not only simplifies the process of mixing and taking cosmetics, but also avoids the possible external pollution caused by traditional methods, and improves the hygiene and convenience of use;

[0029] 2. Since the first installation cylinder and the second installation cylinder are detachably connected, it is more convenient for the user to install and disassemble the cylinder, making the assembly and disassembly of the entire cylinder more convenient and also convenient for cleaning the inside;

[0030] 3.

[0038] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0039] The terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. Unless otherwise defined, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this application pertains. The "first", "second" and similar terms used in this application do not denote any order, quantity or importance, but are only used to distinguish different components.

[0040] A cosmetic container provided by an embodiment of this application, referring to Figure 1 , the cosmetic container includes a bottle body 1 and a cap body 2, and the cap body 2 is used to cover the bottle body 1.

[0041] Referring to Figure 2 and Figure 3 , a cylinder is provided inside the bottle body 1, and the diameter of the cylinder is smaller than the inner diameter of the bottle body 1, so that a return channel 5 is formed between the cylinder and the bottle body 1. Both ends of the cylinder are open, and a first isolation part 31 and a second isolation part 42 are provided inside the cylinder, and a cavity 7 is formed between the first isolation part 31 and the second isolation part 42. Two through return holes 41 are also opened on opposite sides of the cylinder, and both return holes 41 communicate with the cavity 7. At the same time, a vent hole 32 is also opened on the first isolation part 31, and the cavity 7 communicates with the outside of the bottle body 1 through the vent hole 32.

[0042] Continue to refer to Figure 2 and Figure 3The cover body 2 has an insert rod 21 integrally formed on the side facing the bottle body 1, and a first insertion hole 33 is provided on the first isolation portion 31, and a second insertion hole 43 is provided on the second isolation portion 42. When the cover body 2 is covered on the bottle body 1, the insert rod 21 will pass through the reflux hole 41 and the air hole 32 in sequence, and the insert rod 21 is slidably matched with these two holes. The diameter of the insert rod 21 is equal to the diameter of the reflux hole 41, and the diameter of the insert rod 21 is equal to the diameter of the air hole 32. When the insert rod 21 is inserted into the reflux hole 41 and the air hole 32 in sequence, the insert rod 21 has a blocking effect on the reflux hole 41 and the air hole 32.

[0043] Continue to refer to Figure 2 and Figure 3 In the process of closing the cover body 2, the insertion rod 21 is inserted into the first insertion hole 33 and the second insertion hole 43 in sequence. Since the insertion rod 21 slides with the reflux hole 41 and the insertion rod 21 slides with the vent hole 32, the insertion rod 21 gradually compresses the space in the cylinder, first causing the gas in the cylinder to flow into the reflux channel 5 from the end of the cylinder, and the gas in the reflux channel 5 flows back into the cavity 7 through the reflux hole 41, and the gas in the cavity 7 flows back into the atmosphere through the vent hole 32. During the reflux process, the gas causes the liquid cosmetics in the bottle body 1 to reflux into the cavity 7 through the reflux channel 5; when the depth of the cosmetics in the cavity 7 is higher than the depth of the reflux hole 41, the cosmetics in the cavity 7 can reflux into the bottle body 1 through the reflux hole 41; when the cover body 2 is removed, the cover body 2 drives the insertion rod 21 to be removed from the second insertion hole 43, releasing the blocking effect of the insertion rod 21 on the second insertion hole 43, and at this time, the liquid cosmetics remaining in the cavity 7 can reflux into the interior of the bottle body 1 through the second insertion hole 43, thereby having a stirring function for the liquid cosmetics.

[0044] Continue to refer to Figure 2 and Figure 3 Specifically, the barrel includes a first mounting barrel 3 and a second mounting barrel 4, both ends of which are open. One end of the first mounting barrel 3 is detachably connected to the bottle mouth of the bottle body 1, and the other end is detachably connected to one end of the second mounting barrel 4. The first isolation portion 31 is disposed inside the first mounting barrel 3, and the second isolation portion 42 is disposed inside the second mounting barrel 4. Such a design makes the assembly and disassembly of the entire barrel more convenient.

[0045] Reference Figure 3 and Figure 4, in order to further enhance the connection stability between the first mounting cylinder 3 and the second mounting cylinder 4, we opened a mounting hole 34 at the end of the first mounting cylinder 3, and also opened an annular groove 35 on the inner side wall of this groove. Correspondingly, an annular flange 46 is provided on the outer side wall at the end of the second mounting cylinder 4. In this way, when the end of the second mounting cylinder 4 is inserted into the mounting hole 34, the annular flange 46 will exactly be located inside the annular groove 35, thus forming a stable plug-in fit relationship, and at the same time increasing the convenience for the staff to install and disassemble the cylinder body.

[0046] Continue to refer to Figure 2 and Figure 3 , in the shape design of the first isolation part 31 and the second isolation part 42, we adopted a hemispherical shell shape. Such a shape is not only beautiful and generous, but also has the functions of storing and stirring liquid cosmetics, making them more uniform. Of course, according to actual needs, they can also be designed into other shapes, such as an inferior spherical shell shape or a superior spherical shell shape, etc.

[0047] Continue to refer to Figure 2 and Figure 3 , multiple bumps 44 are added at the end of the second mounting cylinder 4, and the multiple bumps 44 are evenly arranged in the circumferential direction. A return groove 45 is naturally formed between two adjacent bumps 44. In this way, the return channel 5 can be interconnected with the inside of the second mounting cylinder 4 through these return grooves 45, enabling the cosmetics to smoothly flow from the inside of the second mounting cylinder 4 into the return channel 5, and then flow back into the cavity 7 through the return holes 41, thereby improving the stirring efficiency.

[0048] Refer to Figure 2 , in addition, at the end of the insertion rod 21, we also added an elastic applicator head 22, and this elastic applicator head 22 can undergo elastic deformation. When the insertion rod 21 is inserted into the first jack 33 and the second jack 43, the elastic applicator head 22 will form a sliding fit relationship with these two jacks. Due to the elastic deformation characteristic of the elastic applicator head 22, it can better adapt to the shape and size changes of the jacks, thus ensuring that the insertion rod 21 can be inserted into the jacks more stably and reliably.

[0049] Continue to refer to Figure 2, when the lid 2 is closed, the insertion rod 21 and the elastic applicator head 22 at its end sequentially enter the first insertion hole 33 and the second insertion hole 43. During this process, the elastic applicator head 22 undergoes elastic deformation, helping the insertion rod 21 to pass through the holes more smoothly and reducing the frictional resistance at the same time. As the insertion rod 21 goes deeper, the cosmetics are pushed and flow within the cylinder and the reflux channel 5, achieving automatic stirring. When the elastic applicator head 22 contacts the liquid cosmetics, it further promotes the uniform mixing of the cosmetics by virtue of its adsorptivity. The evenly stirred cosmetics flow into the cavity 7 through the reflux holes 41. After the insertion rod 21 and the elastic applicator head 22 are fully inserted, they form a seal for the cavity 7, ensuring the storage safety and hygiene of the cosmetics. Before makeup application, when the lid 2 is opened, the insertion rod 21 and its elastic applicator head 22 are withdrawn from the second insertion hole 43. The elastic applicator head 22, by virtue of its adsorptivity, not only brings out the cosmetic pieces stored in the cavity 7 but also ensures that these cosmetic pieces remain at a certain level of humidity and uniformity when taken out, directly enhancing the makeup effect. If there is a small amount of liquid cosmetics remaining in the cavity 7, it will also be brought out together with the insertion rod 21 by the adsorption of the elastic applicator head 22, or naturally flow back into the bottle body 1 through the ventilation holes 32, further maintaining the uniform state of the cosmetics. The design of the elastic applicator head 22 not only optimizes the insertion process of the insertion rod 21 but also enhances the stirring, storage, and dispensing effects of the cosmetics. It not only improves the uniformity and usability of the cosmetics, reduces the risk of external contamination, but also brings a more efficient and hygienic makeup experience for users.

[0050] Continue to refer to Figure 2 , the diameter of the elastic applicator head 22 is also designed to be larger than that of the insertion rod 21, which can further increase the sealing performance between the insertion rod 21 and the insertion hole, effectively preventing the leakage of cosmetics from the insertion hole.

[0051] Continue to refer to Figure 2 , in order to further enhance the connection stability between the elastic applicator head 22 and the insertion rod 21, a mounting rod 23 is fixedly arranged at the end of the elastic applicator head 22, and a mounting hole 34 is correspondingly opened at the end of the insertion rod 21. In this way, the mounting rod 23 can form a plug-in fit with the mounting hole 34, thereby ensuring that the elastic applicator head 22 can be firmly connected to the insertion rod 21 and will not fall off or become loose during use.

[0052] Refer to Figure 5 , the cosmetic container further includes an outer lid 6, and the outer lid 6 is detachably connected to the bottle body 1. When the outer lid 6 covers the bottle body 1, the lid 2 is located inside the outer lid 6. The outer lid 6 has a protective effect on the lid 2 and increases the cleanliness of the surface of the lid 2.

[0053] The implementation principle of this embodiment is as follows: in the cosmetic bottle body 1, the barrel and the reflux channel 5 are both filled with cosmetics, while the cavity 7 is connected to the atmosphere through the air vent 32, allowing the gas to flow freely; when the cover body 2 begins to close, the insertion rod 21 first enters the first insertion hole 33, and then continues to penetrate into the second insertion hole 43; in this process, the insertion rod 21 is slidably matched with the reflux hole 41 and the air vent 32, gradually compressing the space in the barrel, pushing the cosmetics to flow in the barrel and the reflux channel 5, and realizing automatic stirring of the cosmetics; at the same time, the gas in the cavity 7 flows smoothly back to the atmosphere through the air vent 32 to ensure the internal pressure balance; the stirred cosmetics flow into the cavity 7 through the reflux hole 41, at which time the insertion rod 21 has been fully inserted, forming an effective blockage for the cavity 7, ensuring that the stirred cosmetics are safely stored in the cavity 7; this design not only improves the uniformity of the cosmetics, but also facilitates subsequent use; when applying makeup, removing the cover body 2 will drive the insertion rod 21 to be pulled out of the second insertion hole 43. When the end of the plug rod 21 is pulled out, the cosmetic sheet stored in the cavity 7 is taken out and used directly for makeup, which significantly improves the convenience of use and the makeup effect; at the same time, the liquid cosmetics that may remain in the cavity 7 naturally flow back to the inside of the bottle body 1 through the second plug hole 43, which also promotes the further mixing of the cosmetics and keeps its texture uniform. This design not only simplifies the mixing and taking process of cosmetics, but also avoids the possible external pollution caused by the traditional method, and improves the hygiene and convenience of use.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
