Description

Technical Field

[0001] This utility model relates to the field of lip gloss bottle technology, and in particular to a replaceable lip gloss bottle. Background Technology

[0002] A lip gloss bottle is a small container used for storing and applying lip gloss; it is a common item in cosmetics. In existing patents, the applicant filed a Chinese patent application with application number 201810974470.6, disclosing a piston-type lip gloss bottle, including a bottle body, a cap, and a lip gloss assembly, as well as a middle sleeve and a piston. The two ends of the middle sleeve are respectively connected to the bottle body and the cap. The middle sleeve is rotatably connected to the bottle body and fixedly connected to the lip gloss assembly. The lip gloss assembly includes a lip tip and a hollow tube connected to the lip tip. The piston is screwed to the hollow tube and moves along the length of the hollow tube. The piston is used to extrude the lip gloss from the bottle body. The hollow tube is detachably connected to the middle sleeve. A gap is set between the end of the hollow tube and the bottle body. The outer diameter of the piston is larger than the inner diameter of the bottle body. The piston is made of soft rubber. The bottle body, hollow tube, and piston form a first cavity. By setting the piston and hollow tube inside the bottle body, and screwing the piston to the hollow tube, the relative rotation of the hollow tube and the piston causes the lip gloss inside the bottle to flow out through the hollow tube. The outflow amount is controlled by the number of rotations of the hollow tube, thereby controlling the amount of lip gloss used and avoiding unnecessary waste of lip gloss. While the patent document describes controlling the amount of lip gloss dispensed by rotating the hollow tube, this relies solely on the user's sense of touch or visual estimation. This lack of precise control leads to waste, and all stops are simultaneously compressed. If the ribs are not fully rotated, they continue to press downwards, causing damage or failure. Damage to the stops further restricts rotation, preventing the sleeve from rotating in one direction and hindering stable and accurate application of the lip gloss. Therefore, the patent exhibits significant drawbacks and urgently requires a solution. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a replaceable lip gloss bottle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A replaceable lip gloss bottle includes a bottle body, a piston, a screw, a lip tip assembly, and a rotating sleeve. The bottle body has two sets of one-way stopping structures symmetrically arranged at the bottle opening. Each set of one-way stopping structures includes a notch recessed into the bottle opening, two elastic cantilever arms extending from opposite side walls of the notch, and a one-way stopping block on the top surface of the elastic cantilever arms. An elastic deformation space exists between the bottom surface of the elastic cantilever arm and the bottom wall of the notch. A guide slope and a stopping surface are respectively provided on both sides of the one-way stopping block. The piston is slidably connected to the inner wall of the bottle body, and the piston is threaded onto the outside of the screw, which extends into... Inside the bottle body, a snap-fit ​​ring is provided on the top side wall of the screw. The bottom of the rotating sleeve is rotatably fitted outside the bottle mouth. Multiple snap-fit ​​strips are arranged in a ring array on the middle inner wall of the rotating sleeve. The snap-fit ​​ring is installed inside the rotating sleeve and snapped between the multiple snap-fit ​​strips. The snap-fit ​​ring is located above the bottle mouth. The lip assembly is located on the top of the rotating sleeve. A through hole is opened axially on the screw. The lip assembly communicates with the top of the through hole. In the same set of one-way stop structures, when the stopping face of one one-way stop block stops one snap-fit ​​strip, the guide slope of another one-way stop block abuts against the bottom end of another snap-fit ​​strip.

[0005] Furthermore, a slot is formed between two adjacent card strips, and multiple card blocks are provided on the periphery of the card ring, with the card blocks being inserted into the slot.

[0006] Furthermore, an inner ring is provided on the top inner wall of the rotating sleeve, and a convex ring is provided on the middle inner wall of the rotating sleeve, with a snap ring positioned between the inner ring and the convex ring.

[0007] Furthermore, the lip assembly includes a liquid inlet nozzle, a mounting base installed on the top surface of the rotating sleeve, and a lip gloss head installed on the mounting base. The bottom surface of the mounting base is provided with an external threaded cylinder, and the inner hole of the inner ring is provided with an internal thread. The external threaded cylinder is screwed to the internal thread. The liquid inlet nozzle passes through the center of the external threaded cylinder and the mounting base and is inserted into the lip gloss head. The bottom end of the liquid inlet nozzle extends into the rotating sleeve and communicates with the through hole.

[0008] Furthermore, the liquid nozzle includes a sleeve and a connecting tube disposed on the top surface of the sleeve. The bottom end of the connecting tube is connected to the inner cavity of the sleeve. The connecting tube passes through the center of the external threaded cylinder and the mounting base and is inserted into the lip gloss head. The top surface of the snap ring is recessed with a cavity. The bottom wall of the cavity is surrounded by a protruding insert cylinder. The sleeve is fitted over the insert cylinder and is housed in the cavity.

[0009] Furthermore, the lip tip assembly also includes a cover fitted onto the top of the mounting base, the cover being used to limit the top of the lip gloss tip on the mounting base, the top of the lip gloss tip extending beyond the cover.

[0010] Furthermore, the top surface of the mounting base is provided with multiple pointed blocks, which can be inserted into the lip gloss tip; the inner wall of the outer sleeve is provided with multiple inner positioning strips in a circular array, and the periphery of the mounting base is provided with several outer positioning strips in a circular array, with one outer positioning strip located between two adjacent inner positioning strips; the bottom periphery of the mounting base is provided with a snap-fit ​​edge, and the inner wall of the outer sleeve is recessed with a snap-fit ​​groove, with the snap-fit ​​edge snapping into the snap-fit ​​groove.

[0011] Furthermore, the bottom surface of the mounting base is provided with at least two snap-fit ​​blocks, and the top surface of the rotating sleeve is provided with at least two elastic hooks, with one snap-fit ​​block corresponding to one elastic hook; the snap-fit ​​block can be screwed into the elastic hook and snap-fit ​​with the elastic hook.

[0012] Furthermore, the bottom end of the card strip is provided with a guide surface, which is used to slide against the guide slope.

[0013] Furthermore, the inner wall of the rotating sleeve is provided with an annular groove, which is located below all the locking strips, and an annular protrusion is provided around the bottle mouth, which is adapted to the annular groove.

[0014] The beneficial effects of this invention are as follows: In practical application, the bottle contains lip gloss liquid. A unidirectional rotating sleeve drives the locking ring and screw to rotate synchronously. The rotating screw is threadedly connected to the piston and drives the piston to move downward along the inner cavity of the bottle. The downward movement of the piston depends on the angle of the rotating sleeve. The downward-moving piston presses down on the lip gloss liquid in the bottle. The pressurized lip gloss liquid enters the lip tip assembly through the through hole. When the lip tip assembly contains the lip gloss liquid required by the user, it can be applied to the desired location (e.g., the lips). Since the lip gloss liquid in the bottle will only decrease with use, a unidirectional stop structure is used in conjunction with the locking strip to control the rotation of the rotating sleeve to only rotate in one direction, so as to facilitate the squeezing of lip gloss liquid onto the lip tip assembly. Specifically, when the rotating sleeve is rotated, at each certain angle, the retaining strip of the rotating sleeve will first slide against the guide slope to compress the elastic cantilever, causing the elastic cantilever to undergo recoverable elastic deformation inward into the notch. This continues until the retaining strip rotates past the one-way stop block of the elastic cantilever, at which point the elastic cantilever will elastically recover and produce a rebound sound and / or a tactile feedback indicating that the rotating sleeve has reached its rotation position. At this point, the stopping surface of the one-way stop block will prevent the retaining strip from rotating in the opposite direction, thus preventing the rotating sleeve from rotating in the opposite direction. Because multiple retaining strips are arranged in a ring array, a fixed amount of lip gloss is squeezed onto the lip tip assembly each time the rotating sleeve is rotated. In addition, two sets of one-way stopping structures are provided on the bottle mouth. Each set of one-way stopping structures has two one-way stopping blocks. The two one-way stopping blocks of the same set work in a staggered manner, that is, when one one-way stopping block is in the compression stopping action, the other one-way stopping block is in a waiting state. This allows the two one-way stopping blocks to work alternately, avoiding the damage / failure of a single one-way stopping block due to frequent operation. If one of the elastic cantilever arms fails / damages, the one-way stopping block on the other elastic cantilever arm will still perform the one-way stopping function, extending the lifespan of this utility model. This invention extends the lifespan of the rotating sleeve. In the same set of one-way stop structures and two adjacent locking strips of the rotating sleeve, one locking strip is blocked by the stopping surface of a one-way stop block and cannot rotate in the reverse direction. At this time, the bottom end of the other locking strip is located at the guide slope of another one-way stop block and abuts against it. That is, the two adjacent locking strips of the rotating sleeve are located between the two one-way stop blocks of the same set of one-way stop structures, limiting the rotation of the rotating sleeve. This ensures that the angle of each rotation of the rotating sleeve is fixed, thus enabling the quantitative squeezing of lip gloss onto the lip tip assembly. This invention, by setting two sets of one-way stop structures and two one-way stop blocks in each set, ensures the stability of the rotating sleeve's rotation relative to the bottle opening, extends its lifespan, and enables a fixed angle of rotation for each rotation, achieving quantitative squeezing of lip gloss. This helps users control the amount of lip gloss needed and prevents unnecessary waste due to excessive squeezing. Attached Figure Description

[0024] like Figures 1 to 8As shown, this utility model provides a replaceable lip gloss bottle, which includes a bottle body 1, a piston 2, a screw 3, a lip tip assembly 4, and a rotating sleeve 5. The bottle body 1 has two sets of one-way stopping structures 6 symmetrically arranged at its bottle opening 40. Each set of one-way stopping structures 6 includes a notch 7 recessed into the bottle opening 40 of the bottle body 1, two elastic cantilever arms 8 extending from the two opposite side walls of the notch 7, and a one-way stopping block 9 disposed on the top surface of the elastic cantilever arm 8. There is an elastic deformation space between the bottom surface of the elastic cantilever arm 8 and the bottom wall of the notch 7. The one-way stopping block 9 has a guide slope 10 and a stopping surface 11 respectively disposed on both sides. The piston 2 is slidably connected to the inner wall of the bottle body 1, and the piston 2 is threaded onto the screw 3. The screw 3 extends into... Inside the inner cavity of the bottle body 1, a snap ring 12 is provided on the top side wall of the screw 3. The bottom of the rotating sleeve 5 is rotatably fitted outside the bottle mouth 40 of the bottle body 1. Multiple snap bars 13 are arranged in a ring array on the middle inner wall of the rotating sleeve 5. The snap ring 12 is installed inside the rotating sleeve 5 and snapped between the multiple snap bars 13. The snap ring 12 is located above the bottle mouth 40 of the bottle body 1. The lip assembly 4 is provided on the top of the rotating sleeve 5. The screw 3 has an axial through hole 14. The top of the lip assembly 4 is connected to the through hole 14. In the same set of one-way stop structures 6, when the stop surface 11 of one one-way stop block 9 stops one snap bar 13, the guide slope surface 10 of another one-way stop block 9 abuts against the bottom end of another snap bar 13.

[0025] In practical applications, the bottle 1 contains lip gloss liquid. A one-way rotating sleeve 5 rotates, causing the locking ring 12 and screw 3 to rotate synchronously. The rotating screw 3 is threadedly connected to the piston 2 and drives the piston 2 to move downwards along the inner cavity of the bottle 1. The downward movement of the piston 2 depends on the angle of the rotating sleeve 5. The downward movement of the piston 2 will press down the lip gloss liquid in the bottle 1. The pressed lip gloss liquid will enter the lip tip assembly 4 through the through hole 14. When the lip tip assembly 4 contains the lip gloss liquid required by the user, the lip gloss liquid can be applied to the desired location (such as the lips) through the lip tip assembly 4. Since the lip gloss liquid in the bottle 1 will only decrease with use, in order to facilitate the squeezing of the lip gloss liquid onto the lip tip assembly 4, a one-way stop structure 6 cooperates with the locking strip 13 to control the rotating sleeve 5 to rotate only in one direction. Specifically, when rotating the rotating sleeve 5, at each certain angle of rotation, the retaining strip 13 of the rotating sleeve 5 will first slide against the guide slope 10 to compress the elastic cantilever 8, causing the elastic cantilever 8 to undergo recoverable elastic deformation into the notch 7. This continues until the retaining strip 13 rotates beyond the one-way stop block 9 of the elastic cantilever 8. At this point, the elastic cantilever 8 will elastically recover and produce a rebound sound and / or a tactile sensation indicating that the rotating sleeve 5 has reached the correct rotation position. Then, the stop surface 11 of the one-way stop block 9 will prevent the retaining strip 13 from rotating in the opposite direction, thus preventing the rotating sleeve 5 from rotating in the opposite direction. Because the multiple retaining strips 13 are arranged in a ring array, each rotation of the rotating sleeve 5 will squeeze a specific amount of lip gloss onto the lip tip assembly 4. In addition, two sets of one-way stopping structures 6 are provided on the bottle mouth 40 of the bottle body 1. Each set of one-way stopping structures 6 has two one-way stopping blocks 9. The two one-way stopping blocks 9 of the same set of one-way stopping structures 6 work in a staggered manner. That is, when one one-way stopping block 9 is in the compression stopping operation, the other one-way stopping block 9 is in a waiting state. This allows the two one-way stopping blocks 9 to work alternately, avoiding the damage / failure of a single one-way stopping block 9 due to frequent operation. If one of the elastic cantilever arms 8 fails / damages, the one-way stopping block 9 on the other elastic cantilever arm 8 will still play the one-way stopping role, thus extending the service life of this utility model. In the same set of one-way stop structures 6 and two adjacent retaining strips 13 of rotating sleeve 5, one retaining strip 13 of rotating sleeve 5 is blocked by the stop surface 11 of one-way stop block 9 and cannot rotate in the reverse direction. At this time, the bottom end of the other retaining strip 13 is located at the guide slope 10 of another one-way stop block 9 and abuts against the guide slope 10. That is, the two adjacent retaining strips 13 of rotating sleeve 5 are located between the two one-way stop blocks 9 of the same set of one-way stop structures 6 and limit the rotation sleeve 5, so that the angle of rotating sleeve 5 is fixed every time it rotates, and thus the lip gloss liquid can be quantitatively squeezed onto the lip tip assembly 4.This invention, by setting two sets of one-way stop structures 6 and each set of one-way stop structures 6 having two one-way stop blocks 9, ensures the stability of the rotation of the rotating sleeve 5 relative to the bottle mouth 40 of the bottle body 1, extends its service life, and can achieve a fixed angle of rotation of the rotating sleeve 5 each time, so as to achieve quantitative squeezing of lip gloss liquid, which helps users control the amount of lip gloss liquid needed and prevents unnecessary waste caused by squeezing out too much lip gloss liquid.

[0026] In this embodiment, a slot 16 is formed between two adjacent locking strips 13, and multiple locking blocks 15 are provided on the periphery of the locking ring 12, with the locking blocks 15 locking into the slot 16. This structural design ensures that the locking ring 12 can rotate synchronously with the rotating sleeve 5.

[0027] In this embodiment, an inner ring 17 is provided on the top inner wall of the rotating sleeve 5, and a protruding ring 18 is provided on the middle inner wall of the rotating sleeve 5. A snap-fit ​​ring 12 is snapped between the inner ring 17 and the protruding ring 18. This structural design can prevent the snap-fit ​​ring 12 from detaching from the rotating sleeve 5.

[0028] In this embodiment, the lip tip assembly 4 includes a liquid inlet nozzle 19, a mounting base 20 mounted on the top surface of the rotating sleeve 5, and a lip gloss tip 21 mounted on the mounting base 20. The bottom surface of the mounting base 20 is provided with an external threaded cylinder 22, and the inner hole of the inner ring 17 is provided with an internal thread 23. The external threaded cylinder 22 is screwed to the internal thread 23. The liquid inlet nozzle 19 passes through the center of the external threaded cylinder 22 and the mounting base 20 and is inserted into the lip gloss tip 21. The bottom end of the liquid inlet nozzle 19 extends into the rotating sleeve 5 and communicates with the through hole 14.

[0029] In practical applications, the lip gloss liquid inside the through hole 14 is squeezed into the liquid inlet 19, and the lip gloss liquid inside the liquid inlet 19 flows onto the lip gloss head 21 to achieve the supply of lip gloss liquid. In addition, because the mounting base 20 is threadedly connected to the inner thread 23 of the inner ring 17 of the rotating sleeve 5 through the external threaded cylinder 22, the lip head assembly 4 and the rotating sleeve 5 can be disassembled and assembled. When the lip head assembly 4 is damaged or a different model of lip head assembly 4 is required, the lip head assembly 4 can be replaced separately.

[0030] In this embodiment, the liquid inlet 19 includes a sleeve 24 and a connecting pipe 25 disposed on the top surface of the sleeve 24. The bottom end of the connecting pipe 25 communicates with the inner cavity of the sleeve 24. The connecting pipe 25 passes through the center of the external threaded cylinder 22 and the mounting base 20 and is inserted into the lip gloss head 21. The top surface of the snap ring 12 is recessed with a cavity 26. The bottom wall of the cavity 26 is surrounded by a protruding insert cylinder 27 around the through hole 14. The sleeve 24 is fitted over the insert cylinder 27 and is housed within the cavity 26. This structural design not only facilitates the assembly of the snap ring 12, the lip assembly 4, and the rotating sleeve 5, making the three components compact, but also ensures a sealed connection between the lip assembly 4 and the through hole 14 of the screw 3.

[0031] In this embodiment, the lip tip assembly 4 further includes an outer sleeve 28 fitted onto the top of the mounting base 20. The outer sleeve 28 is used to limit the top of the lip gloss tip 21 onto the mounting base 20, with the top of the lip gloss tip 21 extending beyond the outer sleeve 28. This structural design, by limiting the lip gloss tip 21 onto the mounting base 20 through the outer sleeve 28, prevents the lip gloss tip 21 from detaching from the mounting base 20, thus improving the stability of use.

[0032] In this embodiment, the top surface of the mounting base 20 is provided with a plurality of pointed blocks 29, which can be inserted into the lip gloss head 21, so that the lip gloss head 21 can be firmly installed on the mounting base 20.

[0033] In this embodiment, the inner wall of the outer sleeve 28 is arranged in a circular array with multiple inner positioning strips 30, and the periphery of the mounting base 20 is arranged in a circular array with several outer positioning strips 31, with one outer positioning strip 31 located between two adjacent inner positioning strips 30; the bottom periphery of the mounting base 20 is provided with a snap-fit ​​edge 32, and the inner wall of the outer sleeve 28 is recessed with a snap-fit ​​groove 33, with the snap-fit ​​edge 32 snapping into the snap-fit ​​groove 33. This structural design makes the assembly of the outer sleeve 28 and the mounting base 20 convenient and secure.

[0034] In this embodiment, the bottom surface of the mounting base 20 is also provided with at least two snap-fit ​​blocks 34, the external threaded cylinder 22 is located between all the snap-fit ​​blocks 34, and the top surface of the rotating sleeve 5 is provided with at least two elastic hooks 35. One snap-fit ​​block 34 and one elastic hook 35 are correspondingly engaged; the snap-fit ​​block 34 can be screwed into the elastic hook 35 and snap-fit ​​with the elastic hook 35.

[0035] During the process of screwing the external threaded cylinder 22 and the inner ring 17 of the rotating sleeve 5 into the internal thread 23, when the snap-fit ​​block 34 is screwed into the elastic snap hook 35 and snaps into the elastic snap hook 35, it proves that the lip assembly 4 and the rotating sleeve 5 are installed in place, preventing the external threaded cylinder 22 and the internal thread 23 from being over-threaded and damaging the threads, and improving the assembly firmness of the lip assembly 4 and the rotating sleeve 5.

[0036] In this embodiment, the bottom end of the locking strip 13 is provided with a guide surface 36, which is used to slide against the guide ramp 10. The guide surface 36 facilitates the locking strip 13 to slide along the guide ramp 10 and press against the elastic cantilever 8 until the locking strip 13 slides past the one-way stop block 9.

[0037] In this embodiment, the inner wall of the rotating sleeve 5 is provided with an annular groove 37, which is located below all the retaining strips 13. An annular protrusion 38 is provided around the bottle mouth 40 of the bottle body 1, and the annular protrusion 38 is adapted to the annular groove 37. Through the cooperation of the annular groove 37 and the annular protrusion 38, the rotating sleeve 5 and the bottle mouth 40 of the bottle body 1 are firmly assembled and not easily separated.

[0038] Specifically, the replaceable lip gloss bottle also includes a cap 39, which is used to cover the lip tip assembly 4. The cap 39 protects the lip gloss tip 21 of the lip tip assembly 4.

[0039] Specifically, a guide block is provided on the periphery of the piston 2, and a guide groove is provided vertically on the inner wall of the bottle body 1. The guide block is slidably disposed in the guide groove. Through the sliding cooperation between the guide block and the guide groove, it is ensured that the piston 2 can only move downward in a straight line along the inner wall of the bottle body 1.

[0040] Alternatively, the friction between the peripheral wall of piston 2 and the inner wall of bottle 1 may be greater than the torque on piston 2, so when screw 3 rotates, piston 2 can only move straight down along the inner wall of bottle 1.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
