Description

Technical Field

[0001] The utility model relates to the field of cosmetics, and particularly relates to a cosmetic bottle. Background Art

[0002] Cosmetics are a kind of cosmetic products similar to lip gloss and lipstick, usually in liquid or semi-solid form and having a certain gloss. Cosmetics are usually a mixture of various ingredients. If left standing for a long time, the different ingredients in the cosmetics may separate. Using them directly without stirring may result in uneven color when applied to the lips, affecting the overall makeup effect.

[0003] However, most current cosmetics are composed of a cap with an applicator stick and a bottle body containing the cosmetics. However, the length of the applicator stick is limited and cannot fully stir the cosmetics. If a stirring tool is inserted from the outside to stir, it is very likely that impurities and bacteria will be introduced into the cosmetics, contaminating the cosmetics. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0012] In the above design, first, by providing a driving sleeve and a bottle body sleeved in the tube body, which is rotatably connected to the driving sleeve, a double-layer bottle body structure is formed. The relative rotation of the double-layer bottle body can stir the cosmetics without opening the bottle cap, preventing impurities and bacteria from entering the inner cavity of the driving sleeve to contaminate the cosmetics during stirring. Secondly, a central shaft tube and a movable sleeve are provided. The central shaft tube has a spiral protrusion, and the arc-shaped groove is provided in the hole where the movable sleeve cooperates with the driving rod, so that the arc-shaped groove and the spiral protrusion adopt a matching meshing structure, and then the movable sleeve is in spiral cooperation with the central shaft tube. The upper part of the central shaft tube is connected to the tube body, and a strip-shaped protrusion is provided on the outer side of the movable sleeve, and the strip-shaped protrusion cooperates with the strip-shaped groove of the sleeve, so that when the double-layer bottle body rotates relatively to stir, the movable sleeve can slide up and down in the first gap to stir the cosmetics; finally, there is a channel for the cosmetics to flow between the inner cavity of the central shaft tube and the space outside the central shaft tube. The fluid cosmetics flow and turn over through the channel in the first gap and the inner cavity of the central shaft tube to achieve the stirring effect and prevent the cosmetics from being stratified up and down, which affects the makeup effect.

[0016] Preferably, the through holes are evenly distributed throughout the entire central shaft tube, and the spiral protrusions are evenly arranged throughout the entire central shaft tube. The through holes are sandwiched between two adjacent threads of the spiral protrusions. The through holes are evenly distributed throughout the entire central shaft tube, so that when the movable sleeve moves in the first gap, the fluid cosmetic passes through the through holes and flips up and down between the first gap and the inner cavity of the central shaft tube, achieving a stirring effect and preventing the cosmetic from stratifying.

[0017] Preferably, the bottom surface of the central shaft tube abuts against the bottom of the driving sleeve, and a bottom protrusion inserted into the central shaft tube is provided on the bottom of the driving sleeve. By providing a bottom protrusion inserted into the central shaft tube at the bottom of the driving sleeve, it is convenient to align the position of the central shaft tube and make its rotation smooth.

[0018] Preferably, the bottom of the central shaft tube is provided with a first flanging extending outward. The outer diameter of the first flanging is larger than the inner diameter of the movable sleeve but smaller than the inner diameter of the driving sleeve.

[0020] Preferably, the inner diameter of the bottle body changes suddenly in the upper part, so that a first step structure is formed at the mutation. The annular protrusion is located below the first step structure, so that a receiving space is formed between the first step structure and the annular protrusion. The top of the central shaft tube is provided with a second flanging extending outward. The second flanging is inserted into the receiving space, and the outer side wall of the second flanging abuts against the inner side wall of the bottle body. The second flanging is used as the second sealing structure. The first step structure abuts against the second flanging from above to ensure that the central shaft tube will not fall off either.

[0021] Preferably, the top surface of the second flanging abuts against the step structure, and the top surface of the driving sleeve abuts against the bottom surface of the second flanging.

[0038] Embodiment 1

[0039] Referring to Figures 1 to 3 , this embodiment provides a cosmetic bottle with a rotatable bottle body, including a bottle body 1 and a bottle cap 2.

[0040] The bottle body 1 is tubular, and a lower opening is provided below the bottle body 1;

[0041] It further includes a driving sleeve 3 which is tubular, with its lower part closed and upper part open; the bottle body 1 is sleeved outside the driving sleeve 3, and a rotatable first sealing structure is provided between the bottle body 1 and the driving sleeve 3, and the bottom of the driving sleeve 3 is exposed outside the bottle body 1;

[0042] It further includes a central shaft tube 4 which is tubular. The upper end of the central shaft tube 4 is connected inside the bottle body 1 through a non-rotatable second sealing structure. The lower part of the central shaft tube 4 is inserted into the driving sleeve 3, and a first gap is provided between the central shaft tube 4 and the driving sleeve 3. An activity sleeve 5 is arranged in the first gap. A channel for the flow of cosmetics is provided on the central shaft tube to connect the inner cavity of the central shaft tube 4 with the space outside the central shaft tube 4;

[0043] It further includes an activity sleeve 5 which is tubular. An arc-shaped groove is provided on the inner side wall of the sleeve, and a spiral protrusion 41 matching the arc-shaped groove is provided on the outer side wall of the central shaft tube 4. The spiral protrusion 41 is inserted into the arc-shaped groove, and the spiral protrusion 41 spirals around the central axis of the central shaft tube 4; a strip-shaped protrusion 51 is provided on the outer side wall of the activity sleeve 5, and a strip-shaped groove 31 matching the strip-shaped protrusion 51 is provided on the inner side wall of the driving sleeve 3. The strip-shaped protrusion 51 is inserted into the strip-shaped groove 31, and the extending direction of the strip-shaped protrusion 51 is parallel to the central axis of the activity sleeve 5.

[0044] By providing the driving sleeve 3 and the bottle body 1 sleeved in the tube body, which is rotatably connected to the driving sleeve 3, a double-layer bottle body 1 structure is formed. The double-layer bottle body 1 can stir the cosmetics without opening the bottle cap 2 during relative rotation, preventing impurities and bacteria from entering the inner cavity of the driving sleeve 3 to contaminate the cosmetics during stirring. Secondly, the central shaft tube 4 and the activity sleeve 5 are provided. The central shaft tube 4 has a spiral protrusion 41, and the hole of the activity sleeve 5 cooperating with the driving rod has an arc-shaped groove, so that the arc-shaped groove and the spiral protrusion 41 adopt a matching meshing structure, and further the activity sleeve 5 is in spiral cooperation with the central shaft tube 4. The upper part of the central shaft tube 4 is connected to the tube body, and a strip-shaped protrusion 51 is arranged on the outside of the activity sleeve 5. The strip-shaped protrusion 51 cooperates with the strip-shaped groove 31 of the sleeve, so that when the double-layer bottle body 1 rotates relatively to stir, the activity sleeve 5 can slide up and down in the first gap to stir the cosmetics; finally, a channel for the flow of cosmetics is provided between the inner cavity of the central shaft tube 4 and the space outside the central shaft tube 4. The fluid cosmetics are turned over through the channel between the first gap and the inner cavity of the central shaft tube 4 to achieve the stirring effect and prevent the cosmetics from being stratified up and down, affecting the makeup effect.

[0045] A second gap is provided between the bottom surface of the central shaft tube 4 and the bottom surface of the driving sleeve 3, and the second gap is used as a channel; by providing the second gap, the relative rotation of the central shaft tube 4 and the driving sleeve 3 is facilitated.

[0046] A through hole 42 is formed in the side wall of the central shaft tube 4 and serves as a passage. By providing the through hole 42, it is convenient for the fluid cosmetic to fill the first gap between the central shaft tube 4 and the driving sleeve 3 through the inner cavity passage of the central shaft tube 4.

[0047] The through hole 42 is strip-shaped and is located above the spiral protrusion 41. A first limiting ring 43 that is annular and protrudes outward is provided between the through hole 42 and the spiral protrusion 41. The outer diameter of the first limiting ring 43 is greater than the inner diameter of the movable sleeve 5. By providing the first limiting ring 43, when the movable sleeve 5 moves to the upper end of the spiral protrusion 41, the first limiting ring 43 catches the movable sleeve 5, and the movable sleeve 5 will not move to the upper part of the spiral protrusion 41 and separate, ensuring that the movable sleeve 5 always rotates with the driving sleeve 3 and moves up and down.

[0048] The through holes 42 are evenly distributed throughout the central shaft tube 4, and the spiral protrusions 41 are evenly arranged throughout the central shaft tube 4. The through holes 42 are sandwiched between two adjacent threads of the spiral protrusion 41. The through holes 42 are evenly distributed throughout the central shaft tube 4, so that when the movable sleeve 5 moves in the first gap, the fluid cosmetic flows and turns in the first gap and the inner cavity of the central shaft tube 4 through the through holes 42, achieving a stirring effect and preventing the cosmetic from stratifying.

[0049] The bottom surface of the central shaft tube 4 abuts against the bottom of the driving sleeve 3, and a bottom protrusion inserted into the central shaft tube 4 is provided on the bottom of the driving sleeve 3. By providing the bottom protrusion inserted into the central shaft tube 4 at the bottom of the driving sleeve 3, it is convenient to align the position of the central shaft tube 4 and make its rotation smooth.

[0050] The bottom of the central shaft tube 4 is provided with a first flanging extending outward. The outer diameter of the first flanging is greater than the inner diameter of the movable sleeve 5 but less than the inner diameter of the driving sleeve 3. By providing the first flanging, when the movable sleeve 5 moves to the lower end of the central shaft tube 4, the first flanging catches the movable sleeve 5, and the movable sleeve 5 will not move to the lower end of the central shaft tube 4 and separate, ensuring that the movable sleeve 5 always rotates with the driving sleeve 3 and moves up and down.

[0051] In use, to prevent the cosmetics from stratifying during daily use, rotate the drive sleeve 3. The drive sleeve 3 drives the movable sleeve 5 to rotate. The movable sleeve 5 and the central shaft tube 4 are helically engaged through an annular groove and an annular protrusion. The strip-shaped protrusion 51 on the movable sleeve 5 linearly slides in the strip-shaped groove 31, and the drive sleeve 3 can drive the movable sleeve 5 to rotate through the strip-shaped groove 31. The upper part of the central shaft tube 4 is connected to the bottle body 1. Therefore, the bottle body 1 and the drive sleeve 3 rotate relative to each other, and the movable sleeve 5 and the central shaft tube 4 also rotate relative to each other. The arc-shaped groove and the spiral protrusion 41 are helically engaged. When the movable sleeve 5 and the central shaft tube 4 rotate relative to each other, the movable sleeve 5 slides up and down along the strip-shaped groove 31 to stir the cosmetics. The fluid cosmetics are turned up and down through the through holes 42 in the first gap and the inner cavity of the central shaft tube 4. Stirring prevents the cosmetics from stratifying. Without opening the bottle cap 2, the cosmetics in the bottle cavity are stirred. Without contaminating the whole cosmetics, the cosmetics are stirred, so that the texture of the cosmetics always remains uniform, without stratifying and without being contaminated by stirring, achieving a better makeup effect.
