A rebound lipstick tube

Abstract

The present invention discloses a rebound lipstick tube, comprising a first tube body, a middle tube cover, a limiting mechanism, and a base. A guide block provided on the cover body is mounted within a guide groove of the first tube body. The guide block and the spring between the cover body and the base enable axial movement of the cover body. The middle tube body is nested within the cover body. A clamping mechanism provided at the lower end of the cover body clamps the limiting mechanism. A second, inverted conical limiting block, mounted on the middle section of the limiting mechanism, is larger than the first, conical limiting block of the limiting mechanism. When the lipstick tube is pressed, the second limiting block is larger than the first, causing the clamping mechanism to disengage from the first limiting block and become restrained by the second limiting block. When the lipstick tube is released, the middle tube body rises with the cover body, ejecting from the first tube body for removal and use. After use, the middle tube body is placed in the lipstick tube and pressed down again to return it to its original position. The present invention utilizes a press-and-rebound mechanism to remove the lipstick tube body, resulting in a novel structure and greater convenience than conventional snap-on lipstick tubes.

Description

Technical Field

[0001] The invention belongs to the technical field of cosmetic packaging bottles, in particular to a rebound lipstick tube. Background Art

[0002] Lipstick, a type of cosmetic, primarily adds color to the lips, accentuates their contours, and enhances their appearance. Prior art lipstick tubes typically consist of a cap and a base. Using either a snap-on or magnetic connection, both of which have been established for years, the cap removably snaps onto the base. The cap is first pulled off the base and then rotated relative to it to release the lipstick. However, this lacks new appeal to consumers, necessitating innovative structural innovations in lipstick tubes, offering a different way to open the lipstick and a new form factor to attract consumers. Summary of the Invention

[0003] Aiming at the universality of existing lipstick tube structures, the present invention provides a rebound lipstick tube, which can be used to take out lipstick by pressing the rebound tube.

[0004] In order to achieve innovation in the structure of lipstick tubes to attract more consumers, the present invention solves the problem through the following technical solutions: a rebound lipstick tube, comprising a first tube body and a middle bundle tube body, the middle bundle tube body is nested in a cover body, the rebound lipstick tube comprises a cover body, a limit mechanism, and a base, a clamping mechanism is provided at the lower end of the cover body, a plurality of limit hooks are provided at the lower end of the clamping mechanism, a guide block is provided on the cover body, the first tube body is provided with a guide groove, the guide block is movably provided in the guide groove of the first tube body, a conical first limit block is provided at the upper end of the limit mechanism, an inverted conical second limit block is provided in the middle section of the limit mechanism, the second limit block is sleeved on the middle shaft of the limit mechanism, and the second limit platform at the top of the second limit block is larger than the first limit platform at the bottom of the first limit block of the limit mechanism, the limit hook is limited to the first limit platform of the first limit block, the limit hook is provided with an inclined surface against the second limit block, the limit mechanism is fixedly connected to the base, and a spring is provided between the cover body and the base. When the cam is in the closed position, the cam is released and the cam is in the closed position, so that the cam is in the closed position and the cam is in the closed position, and the cam is in the closed position, so that the cam is in the closed position and the cam is in the closed position. The lipstick tube of the present invention is taken out by pressing and rebounding, and has a novel structure. Compared with the common snap-on lipstick tube, it is more convenient to use.

[0005] In the above technical solution, the cover preferably includes a stopper and a housing. The stopper is mounted on the housing, and the center beam tube is inserted into the housing cavity and secured thereto via the stopper. The clamping mechanism includes a stopper hook connected to the bottom of the housing via a connecting strip. This structure secures the center beam tube within the cover cavity through an interference fit between the upper stopper and the center beam tube. The position of the stopper hook ensures that the clamping mechanism can be smoothly disengaged from the stopper, allowing the cover to rise smoothly.

[0006] In the above technical solution, preferably, a fixing groove is provided at the bottom of the limiting mechanism, and a limiting step is provided at the base. The fixing groove of the limiting mechanism is inserted into the limiting step of the base to fix the limiting mechanism. The use of this structure to fix the limiting mechanism to the base through the fixing groove ensures that the limiting mechanism will not rise with the cover body.

[0007] In the above technical solution, preferably, guide grooves are provided on both sides of the first tube body, and a mounting notch is provided at the upper end of the guide groove on one side of the first tube body. This structure ensures the accuracy of the lipstick's axial movement through the guide grooves, and the provision of the mounting notch facilitates the installation of the cover body into the first tube body.

[0008] Compared with the prior art, the present invention has the following advantageous effects: by pressing the upper end of the lipstick tube, the cover body moves axially under the cooperation of the guide block and the guide groove on the first tube body. During the downward movement of the clamping mechanism, the limit hook separates from the first limit platform. Since the second limit platform at the top of the second limit block is larger than the first limit platform at the bottom of the first limit block of the limit mechanism, the clamping mechanism expands along the inclined surface against the second limit block until it is limited on the second conical surface of the second limit block. At this time, the lipstick tube is released and the middle bundle tube body rises with the cover body under the action of the spring. At the same time, the second limit block cannot rise again after rising to contact with the first limit block. At this time, the limit hook continues to rise under the action of the spring and separates from the second limit block until it rises to the highest point. The middle bundle tube body pops out of the first tube body and is pulled out for use. Since the second limit block has fallen back to its original position freely after separating from the limit hook, after use, the middle bundle tube body is placed in the lipstick tube and pressed down again. The limit hook is again limited on the first limit platform of the first limit block, thereby achieving reset. The lipstick tube of the present invention is taken out by pressing and rebounding, and has a novel structure. Compared with the common snap-on lipstick tube, it is more convenient to use.

[0015] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Figures 1 to 6A rebound lipstick tube includes a first tube body 1 and a middle bundle tube body 2, the middle bundle tube body 2 is nested in the cover body 3, the rebound lipstick tube includes a cover body 3, a limiting mechanism 5, and a base 7. The lower end of the cover body 3 is provided with a clamping mechanism 21, and the lower end of the clamping mechanism 21 is provided with multiple limiting hooks 9. The cover body 3 is provided with a guide block 8, the first tube body 1 is provided with a guide groove 19, and the guide block 8 is movably provided in the guide groove 19 of the first tube body 1. The upper end of the limiting mechanism 5 is provided with a conical first limiting block 12, and the limiting mechanism A second inverted conical limit block 6 is provided in the middle section of the structure 5. The second limit block 6 is sleeved on the intermediate shaft 13 of the limit mechanism 5, and the second limit platform 15 on the top of the second limit block 6 is larger than the first limit platform 17 at the bottom of the first limit block 12 of the limit mechanism 5. The limit hook 9 is limited on the first limit platform 17 of the first limit block 12. The limit hook 9 is provided with an inclined surface 20 that abuts against the second limit block 6. The limit mechanism 5 is fixedly connected to the base 7, and a spring 4 is provided between the cover body 3 and the base 7. With this structure, by pressing the upper end of the lipstick tube, the cover body 3 moves axially under the cooperation of the guide block 8 and the guide groove 19 on the first tube body 1. During the downward movement of the clamping mechanism 21, the limit hook 9 separates from the first limit platform 17. Since the second limit platform 15 at the top of the second limit block 6 is larger than the first limit platform 17 at the bottom of the first limit block 12 of the limit mechanism 5, the clamping mechanism 21 expands along the inclined surface 20 against the second limit block 6 until it is limited to the second conical surface 23 of the second limit block 6. At this time, the lipstick tube is released on the spring. 4, the middle tube body 2 rises along with the cover body 3. Meanwhile, the second stopper 6 rises to contact the first stopper 12 and cannot rise further. At this time, the stopper hook 9, under the action of the spring 4, continues to rise and disengages from the second stopper 6 until it reaches its highest point. The middle tube body 2 pops out of the first tube body 1 and can be removed for use. Since the second stopper 12 has freely fallen back to its original position after disengaging from the stopper hook 9, after use, the middle tube body 2 is placed in the lipstick tube and pressed down again. The stopper hook 9 is again restrained on the first stopper platform 17 of the first stopper 12, thus returning to its original position. The present invention uses a press-and-rebound mechanism to remove the lipstick tube, which has a novel structure and is more convenient to use than ordinary snap-on lipstick tubes.

[0016] In this embodiment, the cover 3 includes a stopper 10 and a housing 11. The stopper 10 is mounted on the housing 11. The center beam tube 2 is inserted into the interior of the housing 11 and secured thereto by the stopper 10. The clamping mechanism 21 includes a stopper hook 9, which is connected to the bottom of the housing 11 via a connecting bar 22. This structure secures the center beam tube 2 to the interior of the cover 3 through an interference fit between the stopper 10 on the cover 3 and the center beam tube 2. The position of the stopper hook 9 ensures that the clamping mechanism 21 can smoothly disengage from the stopper 5, allowing the cover 3 to ascend smoothly.

[0017] In this embodiment, the bottom of the limiting mechanism 5 is provided with a fixing groove 14, and the base 7 is provided with a limiting step 16. The fixing groove 14 of the limiting mechanism 5 is inserted into the limiting step 16 of the base 7 to fix the limiting mechanism 5. The use of this structure ensures that the limiting mechanism 5 is fixed to the base 7 via the fixing groove 14 and does not rise with the cover 3.

[0018] In this embodiment, guide grooves 19 are provided on both sides of the first tube body, and a mounting notch 18 is provided at the upper end of the guide grooves 19 on one side of the first tube body. This structure ensures the accuracy of the lipstick's axial movement through the guide grooves 19, and the provision of the mounting notch 18 facilitates the installation of the cover body 3 into the first tube body 1.

[0019] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
