Description

Technical Field

[0001] This invention relates to the field of cosmetic packaging container technology, and to a lip gloss packaging container, particularly a press-to-pop lip gloss with an automatically pop-out top cover assembly achieved by pressing a button, and its usage method. Background Technology

[0002] Currently, most lip gloss products on the market use a screw-on structure to connect and seal the cap to the bottle. The cap assembly has internal threads on the inside, and the bottle opening has external threads on the outside. Users need to rotate the cap assembly multiple times to open or close it.

[0003] This type of traditional structure has the following shortcomings: First, the opening operation is cumbersome. Users need to use both hands or rotate the top cover multiple times with one hand to open it, which is extremely inconvenient in situations where makeup needs to be touched up urgently or in one-handed operation scenarios.

[0004] Secondly, the closing operation requires proper thread alignment. During the closing process, the user must ensure that the threads are aligned and rotated into place. If not fully engaged, it may result in an incomplete seal, posing a risk of lip gloss leakage or drying out.

[0005] Furthermore, the threads are prone to wear after prolonged use. After repeated engagement and disengagement, the thread structure may experience wear, stripping, and other problems, affecting sealing performance and service life.

[0006] Furthermore, traditional screw-on structures lack a sense of ritual and convenience. As consumers' demands for cosmetic usage experiences continue to rise, traditional screw-on opening methods can no longer meet users' needs for convenient functions such as "one-click opening" and "quick response."

[0007] There is currently no lip gloss packaging container that can automatically pop out the top cover by pressing a button without the need for rotation. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a press-to-pop lip gloss solution to address the technical problems of cumbersome opening and closing of the lip gloss cap, the need for aligned threads when closing, and easy wear and tear after long-term use. This invention, through the design of a button assembly and an elastic element, enables the cap assembly to automatically pop out with a single press, eliminating the need for rotation and improving ease of use and user experience.

[0009] To solve the above-mentioned technical problems, the technical solution of the present invention is: a press-to-dispense lip gloss, comprising: The bottle body is used to contain liquid lip gloss and has an opening at its upper end; The lower end of the middle sleeve is fixedly disposed on the outer periphery of the upper opening of the bottle body; The base has its lower end fixedly disposed on the inner circumference of the upper opening of the bottle body, and its upper end installed inside the upper end of the middle sleeve. The base has a through hole running vertically through it. The upper cover assembly is capable of covering the upper end of the middle sleeve, or opening upwards from above the middle sleeve; The upper end of the support bone is movably connected to the top cover assembly. The upper end of the support bone can slide up and down a set distance within the top cover assembly. The lower end of the support bone is provided with a brush head that can pass through the hole in the base and extend into the inside of the bottle. A button assembly includes a button and a locking element. The locking element is installed between the middle sleeve and the base. When the upper cover assembly covers the upper end of the middle sleeve, the locking element and the upper cover assembly form a locking connection. The button is located on one side of the middle sleeve and can reciprocate relative to the middle sleeve. The button is connected to the locking element and is used to drive the locking element to separate from the upper cover assembly. An elastic element is installed between the upper end of the support bone and the upper end of the cover assembly. When the locking member is engaged with the cover assembly, the elastic element is in a compressed and energy-storing state. When the button drives the locking member to separate from the cover assembly, the elastic element can release elastic potential energy and provide an upward elastic force, pushing the cover assembly to slide upward relative to the support bone and automatically pop up.

[0010] As a further explanation of the present invention: Preferably, the upper cover assembly includes an upper cover and an inner cover. The inner cover is disposed inside the upper cover. The upper end of the support bone is provided with a sliding head. The upper end of the inner cover is provided with a sliding cavity. The sliding head is disposed inside the sliding cavity and can slide up and down inside the sliding cavity. The lower end of the elastic element is installed inside the sliding head. The upper end of the elastic element abuts against the upper end of the inner cover.

[0011] Preferably, the inner wall of the sliding cavity of the inner cover is provided with a vertical groove, and a stop is provided at the lower end of the groove. The outer wall of the sliding head of the support bone is provided with a slider, which is slidably installed in the groove and can slide up and down along the groove. The stop is used to limit the end position of the slider sliding down.

[0012] Preferably, the inner cover is composed of two half-inner covers spliced ​​together, and the splicing position of the half-inner covers is provided with a splicing groove and a splicing strip, and the splicing strip is inserted into the splicing groove.

[0013] Preferably, the locking component is fixedly connected to the button or integrally formed. The upper end of the locking component is provided with a hook, and the lower end of the inner cover is provided with a locking flange that matches the hook. When the upper cover assembly covers the upper end of the middle sleeve, the hook and the locking flange form a locking connection. When the button is pressed, the hook moves with the locking component, and the hook disengages from the locking flange, thereby unlocking.

[0014] Preferably, the engaging component has two mutually symmetrical "C"-shaped elastic arms, which are mounted on the base. When the button is pressed, the "C"-shaped elastic arms undergo elastic deformation. When the button is released, the "C"-shaped elastic arms elastically reset and drive the button to reset.

[0015] Preferably, the press-to-pop lip gloss further includes an inner rubber stopper, which is disposed on the inner side of the upper end of the base. When the upper cover assembly covers the upper end of the middle sleeve, the lower end of the sliding head of the support bone abuts against the upper end face of the inner rubber stopper, and the contact between the sliding head and the inner rubber stopper forms a seal. The inner rubber stopper is provided with a rubber stopper hole for the support bone to pass through.

[0016] Preferably, the upper end of the opening of the bottle body is provided with a limiting protrusion, and the lower end of the base is provided with a limiting groove, the limiting protrusion and the limiting groove engaging with each other.

[0017] Preferably, the elastic element is a spring.

[0018] The present invention also provides a method for using the above-mentioned press-to-dispense lip gloss, comprising the following steps: S1. In the closed state, the upper cover assembly covers the upper end of the middle sleeve, the locking part of the button assembly forms a locking connection with the upper cover assembly, and the elastic element is in a compressed and energy-storing state. S2. When it is necessary to open, press the button to disengage the locking piece from the top cover assembly. S3. The elastic element releases elastic potential energy, pushing the upper cover assembly to slide upward relative to the support bone and automatically popping upward. The upper end of the support bone slides downward a set distance inside the upper cover assembly and is blocked, preventing the support bone from falling. S4. The user pulls the top cover assembly upwards, removes the top cover assembly along with the support bone, and uses the brush head to apply the lip gloss liquid. After application, the lower end of the support bone is pushed down through the hole in the base and inserted into the bottle. The top cover assembly is then placed over the upper end of the middle sleeve, and the top cover assembly is pressed down until the locking parts and the top cover assembly re-engage and the elastic element returns to its compressed and stored state.

[0019] The beneficial effects of this invention are: Firstly, this invention features one-button opening and convenient operation, abandoning the traditional multi-turn rotating opening method of lip glosses. Unlocking is achieved simply by pressing the side button with one hand, and the top cap automatically pops open. No two hands are needed, and alignment of the threads is required; the entire process can be done with one hand. This significantly reduces operation time in quick makeup application scenarios such as touch-ups on the go, commuting, or driving, solving the pain points of traditional rotating caps being cumbersome, jammed, and difficult to open, thus significantly improving efficiency.

[0020] Secondly, this invention features an automatic pop-up mechanism and a novel user experience. It employs an innovative press-to-unlock and elastic pop-up mechanism, allowing the top cover to smoothly and cleanly pop open upon pressing. This distinctly differs from the monotonous operation of ordinary cosmetics, providing a strong sense of ritual and a novel interactive experience. It caters to young consumers' preference for aesthetically pleasing, fun, and technologically advanced beauty products, enhancing product differentiation and market competitiveness.

[0021] Thirdly, the present invention has good sealing and reliable performance. The lower end of the sliding head of the support bone abuts against the upper end face of the inner rubber stopper, and the contact between the sliding head and the inner rubber stopper forms a seal, which can effectively prevent the lip gloss liquid from leaking, evaporating, drying, and contaminating. It will not leak even when carried for a long time or shaken in the bag, and its storage stability is far superior to that of traditional threaded structures.

[0022] Fourth, this invention features a stable structure and long service life. It replaces easily worn threads with a hook-and-engagement flange mechanical snap-fit, preventing issues such as stripping, loosening, or incomplete engagement even after repeated opening and closing. The structure distributes stress evenly and minimizes material loss. The locking force and sealing performance remain stable throughout normal use, significantly extending the overall product lifespan and reducing the failure rate.

[0023] Fifthly, the present invention features a guiding design and smooth ejection. The sliding head of the support is located within the sliding cavity and can slide up and down within it. The lower end of the elastic element is installed within the sliding head, and the upper end of the elastic element abuts against the upper end of the inner cover. The inner wall of the sliding cavity of the inner cover has a vertical groove, and the lower end of the groove has a stop. The outer wall of the sliding head of the support has a slider, which is slidably installed within the groove and can slide up and down along it. The stop is used to limit the endpoint of the slider's downward sliding. This structure allows the upper cover assembly to rise and fall smoothly along the vertical axis without tilting, shaking, or jamming. The ejection process is smooth and stable, improving the operating feel and structural stability. At the same time, it allows users to easily pull it out for use. The structure is simple and highly reliable. The middle sleeve integrates guiding and installation functions, and has a compact structure. The middle sleeve is fixed to the upper part of the bottle and simultaneously provides installation support for the button assembly, reducing the number of parts, lowering the assembly difficulty, and improving the overall structural stability.

[0024] Sixth, this invention features limiting protection to prevent accidental contact and structural damage. A limiting protrusion is provided at the upper end of the bottle opening, and a limiting groove is provided on one side of the lower end of the base. The limiting protrusion and the limiting groove engage with each other. Seventh, the locking mechanism of the button assembly has two symmetrical "C"-shaped elastic arms that can elastically deform or reset themselves. When released, they automatically spring back to their original position, maintaining the unlocking state for the next time. This reduces the probability of accidental touches and makes the product safer and more durable.

[0025] Eighthly, this invention is simple to assemble and use. Closing it only requires pressing down on the top cover for automatic locking, without the need for rotation or alignment. Even the elderly and beginners can quickly learn how to use it. The overall structure is simple, the opening and closing logic is intuitive, and there are no complicated operating steps, significantly reducing the barrier to entry and improving the user experience for all ages.

[0035] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-9 As shown, this invention relates to a press-to-pop lip gloss, comprising a bottle body 8 for containing liquid lip gloss, with an opening 81 at its upper end; a middle sleeve 17, the lower end of which is fixedly disposed on the outer periphery of the upper opening 81 of the bottle body; a base 15, the lower end of which is fixedly disposed on the inner periphery of the upper opening 81 of the bottle body 8, the upper end of which is installed inside the upper end of the middle sleeve 17, and the base 15 having a through-hole 151; and a top cover assembly that covers the upper end of the middle sleeve 17 (see [reference]). Figure 1 and Figure 8 ), or open it from the middle 17 upwards (see Figure 2 and Figure 9The support 1 has an upper end that is movably connected to the top cover assembly. The upper end of the support 1 can slide up and down a set distance within the top cover assembly. The lower end of the support 1 is provided with a brush head 2, which can pass down through the central hole 151 of the base and extend into the bottle to pick up the lip gloss liquid. The button assembly includes a button 3 and a locking component 4. The locking component 4 is installed between the middle sleeve 17 and the base 15. When the top cover assembly covers the upper end of the middle sleeve 17, the locking component 4 and the top cover assembly form a locking connection. The button 3 is located in the middle sleeve 17. On one side of 7, the button 3 can reciprocate relative to the middle sleeve 17. The button 3 is connected to the locking member 4. The button 3 is used to drive the locking member 4 to separate from the upper cover assembly. The elastic element 13 is installed between the upper end of the support rib 1 and the upper end of the upper cover assembly. When the locking member 4 is engaged with the upper cover assembly, the elastic element 13 is in a compressed energy storage state. When the button 3 drives the locking member 4 to separate from the upper cover assembly, the elastic element 13 can release elastic potential energy and provide an upward elastic force, pushing the upper cover assembly to slide upward relative to the support rib 1 and automatically pop upward.

[0037] like Figures 3-5 , Figure 8 and Figure 9 As shown, the upper cover assembly includes an upper cover 5 and an inner cover 6. The inner cover 6 is disposed inside the upper cover 5. The upper end of the support rib 1 is provided with a sliding head 101. The upper end of the inner cover 6 is provided with a sliding cavity 61. The sliding head 101 is disposed within the sliding cavity 61 and can slide up and down within the sliding cavity 61. The lower end of the elastic element 13 is installed within the sliding head 101, and the upper end of the elastic element 13 abuts against the upper end of the inner cover 6. The inner wall of the sliding cavity 61 of the inner cover 6 is provided with a vertical groove 62. The lower end of the groove 62 is provided with a stop block 63. The outer wall of the sliding head 101 of the support rib 1 is provided with a slider 102. The slider 102 is slidably installed within the groove 62 and can slide up and down along the groove 62. The stop block 63 is used to limit the endpoint of the slider 102 sliding downward. Through the cooperation of the groove 62 and the slider 102, the sliding head 101 of the support rib 1 can be prevented from rotating within the sliding cavity 61 of the inner cover 6. When the top cover assembly is placed outside the upper end of the middle sleeve 17, the slider 102 is located at the upper or middle part of the slide groove 62. When the elastic element 13 pops the top cover assembly upward, the slider 102 slides to the lower part of the slide groove 62 and abuts against the stop block 63, forming a limit to prevent the support rib 1 from sliding downward relative to the inner cover 6. When the user needs to remove the top cover assembly for use, the top cover assembly can be pulled upward, at which time the top cover assembly and the support rib 1 can be pulled out as a whole.

[0038] like Figures 3-5 , Figure 8 and Figure 9As shown, the inner cover 6 is composed of two half-inner covers 60 spliced ​​together. The splicing position of the half-inner covers 60 is provided with a splicing groove 14 and a splicing strip 19, and the splicing strip 19 is inserted into the splicing groove 14. This structure allows for convenient injection molding of the inner wall structure of the inner cover 6, which can then be joined together after molding.

[0039] like Figures 3-5 , Figures 7-9 As shown, the engaging component 4 is fixedly connected to or integrally formed with the button 3. The upper end of the engaging component 4 is provided with a hook 11, and the lower end of the inner cover 6 is provided with an engaging flange 12 that matches the hook 11. The upper surface of the engaging flange 12 is a plane or an inclined plane, and the lower surface of the hook 11 is a corresponding plane or an inclined plane. When the upper cover assembly covers the upper end of the middle sleeve 17, the hook 11 and the engaging flange 12 form an engaging connection. When the button 3 is pressed, the hook 11 moves horizontally with the engaging component 4, and the hook 11 disengages from the engaging flange 12, thereby unlocking the device.

[0040] like Figure 7 As shown, the locking component 4 is provided with two mutually symmetrical "C"-shaped elastic arms 41. The "C"-shaped elastic arms 41 are mounted on the base 15. When the button 3 presses the locking component 4, the "C"-shaped elastic arms 41 undergo elastic deformation. When the button 3 is released, the "C"-shaped elastic arms 41 elastically reset and provide a force to reset the button 3.

[0041] like Figures 3-5 , Figure 8 and Figure 9 As shown, the press-to-pop lip gloss also includes an inner rubber stopper 7. The inner rubber stopper 7 is disposed on the inner side of the upper end of the base 15. When the upper cover assembly covers the upper end of the middle sleeve 17, the lower end of the sliding head 101 of the support bone 1 abuts against the upper end face of the inner rubber stopper 7, and the contact between the sliding head 101 and the inner rubber stopper 7 forms a seal. The inner rubber stopper 7 is provided with a rubber stopper hole 71 for the support bone 1 to pass through.

[0042] like Figure 4 and Figure 7 As shown, in order to further improve the connection stability between the bottle body 8 and the base 15, a limiting protrusion 9 is provided at the upper end of the opening of the bottle body 8, and a limiting groove 10 is provided on one side of the lower end of the base 15. The limiting protrusion 9 and the limiting groove 10 cooperate to engage with each other.

[0043] like Figures 3-5 , Figure 8 and Figure 9 As shown, the elastic element can be implemented in various forms, and the elastic element 13 is one of a spring, a sheet, an elastic rubber body, or a gas spring. In this embodiment, the elastic element 13 is selected as a spring.

[0044] When the user presses button 3, button 3 overcomes the elastic force of the "C"-shaped elastic arm of the locking component 4 and moves inward into the bottle body, causing the hook 11 of the locking component 4 to move synchronously, disengaging the hook 11 from the top cover assembly. The elastic element 13 releases its elastic potential energy, pushing the top cover assembly to slide upward relative to the support rib 1 and automatically popping it upward. After the elastic element 13 pops the top cover assembly upward, the slider slides to the lower part of the slide groove and abuts against the stop block, forming a limit to prevent the support rib 1 from sliding downward relative to the inner cover 6. When the user needs to remove the top cover assembly for use, the top cover assembly can be pulled upward. At this time, the top cover assembly and the support rib 1 can be pulled out as a whole, allowing the user to take out the lip gloss liquid dipped in the brush head 2.

[0045] The method for using the press-to-dispense lip gloss according to the present invention includes the following steps: S1. In the closed state, the upper cover assembly covers the upper end of the middle sleeve 17, the snap-fit ​​part 4 of the button assembly forms a snap-fit ​​connection with the upper cover assembly, and the elastic element 13 is in a compressed and energy-storing state. S2. When it is necessary to open, press button 3, and the locking piece 4 will disengage from the upper cover assembly. S3, the elastic element 13 releases elastic potential energy, pushing the upper cover assembly to slide upward relative to the support 1 and automatically popping upward. The upper end of the support 1 slides downward a set distance inside the upper cover assembly and is blocked, preventing the support 1 from falling. S4. The user pulls the top cover assembly upwards, removes the top cover assembly along with the support 1, and uses the brush head to apply the lip gloss liquid. After application, the lower end of the support 1 is passed down through the central hole 151 of the base and inserted into the bottle body. The top cover assembly is then placed over the upper end of the middle sleeve 17, and the top cover assembly is pressed down until the locking part 4 and the top cover assembly re-engage and the elastic element returns to its compressed and stored state.

[0046] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "upper," "lower," etc., indicating orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.
