TITLE OF INVENTION: [A FLIP-TOP FOUNDATION BOTTLE]REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the priority to Chinese patent application No. 202421 1 17951 .2, titled “A FLIP-TOP FOUNDATION BOTTLE", filed on 22 May 2024, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD
[0002] The present disclosure generally relates to the field of cosmetics and specifically relates to cosmetic containers, and more particularly to a flip-top foundation bottle.BACKGROUND
[0003] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge of the person skilled in the art in any jurisdiction as at the priority date of the invention.
[0004] In the cosmetics field, foundation bottles are among the essential containers used in everyday makeup routines. Conventional foundation bottles typically adopt a squeeze-type packaging structure, most of which are sealed by a screw-on outer cap. For example, Chinese Patent Publication No. CN209582353U discloses a squeeze-type foundation bottle with an applicator, which includes a bottle body, an inner sleeve arranged at the opening of the bottle body, and an applicator head snap-fitted to the inner sleeve. An inner plug is provided inside the bottle opening and installed within the inner sleeve, and a return plug is mounted inside the inner plug. The inner plug is configured to comprise a liquid outlet head disposed at its top center, and a valve plate is provided at the center bottom of the return plug. The applicator head is configured to have a central channel that is connected to the liquid outlet head.
[0005] However, in such conventional foundation bottles, the split configuration between the bottle container and the outer cap often makes it difficult to achieve timelyresealing during use, resulting in inadequate sealing performance upon closure. Additionally, in these designs, the inner plug and the return plug are typically secured via an inner sleeve threaded onto the bottle container. If the inner sleeve becomes loosened, the stability of both the inner plug and the return plug is compromised, which can lead to drying, degradation, or leakage of the foundation product. Moreover, the sealing process is generally complex, and the opening and closing operations lack user-friendliness, thereby affecting the overall user experience. Accordingly, a technical problem to be addressed is how to improve the ease of use, sealing reliability, and structural durability of the foundation bottle.
[0006] Thus, there exists a need to develop an improved foundation bottle, addressing at least one of the problems associated with the conventional foundation bottles.SUMMARY
[0007] Specifically, to address the above-mentioned technical problems, the present invention specifically uses the following technical solutions:
[0008] Accordingly, an aspect of the invention refers to a flip-top foundation bottle, comprising: a container body configured to contain foundation; an intermediate cover fixedly mounted to a top of the container body, the intermediate cover having a second opening concentric with a first opening of the container body, the first opening and the second opening being of equal height; a powder outlet nozzle having a lower insertion portion and a middle sealing ring portion, wherein when the insertion portion is inserted into the first opening, the sealing ring portion snugly engages both the first opening and the second opening; a first outer cap hingedly connected to the intermediate cover, the powder outlet nozzle further having an upper tapered powder-dispensing portion; and a sealing post disposed at a center of the first outer cap, wherein when the first outer cap is closed onto the intermediate cover, the sealing post is snugly inserted into a center of the powder-dispensing portion.
[0009] In some embodiments, a surface of the insertion portion comprises a plurality of protruding rings that snugly engage an inner wall of the first opening.
[0010] In some embodiments, an outer diameter of the sealing ring portion is substantially equal to an outer diameter of the second opening.
[0011] In some embodiments, a bottom surface of the first outer cap comprises a recessed region configured to accommodate the second opening and the powder outlet nozzle, and wherein the sealing post is disposed at a center of the recessed region.
[0012] In some embodiments, the flip-top foundation bottle further comprises a hook portion formed on one side of the first outer cap and configured to engage an edge of the intermediate cover so as to retain the first outer cap in a closed position over the intermediate cover.
[0013] In some embodiments, a boss is formed between a top of the container body and the first opening, a side of the boss having a locking groove, and a bottom surface of the intermediate cover comprising a cavity shaped to match the boss, an edge of the cavity having a locking member configured to engage the locking groove.
[0014] In some embodiments, the flip-top foundation bottle further comprises a second outer cap, wherein the first outer cap is fixedly disposed within the second outer cap, and an edge of an opening of the second outer cap is rotatably connected to the intermediate cover via a hinge shaft.
[0015] In some embodiments, an edge of the second outer cap abuts against an outer edge of a top surface of the intermediate cover.
[0016] In some embodiments, the powder-dispensing portion comprises a contact portion configured to cooperate with a bottom surface of the first outer cap, such that when the first outer cap is closed onto the intermediate cover, the sealing post is snugly inserted into the powder-dispensing portion and the bottom surface of the first outer cap abuts the contact portion.
[0017] In some embodiments, a top of the powder-dispensing portion comprises a powder outlet, and an inner diameter of the powder outlet gradually decreases from top to bottom to form a guiding slope, and wherein the contact portion is circumferentially disposed along a top edge of the powder outlet.
[0018] In some embodiments, the flip-top foundation bottle further comprises a spacer disposed between the hook portion and a bottom of the first outer cap, such that when the hook portion is engaged in a first locking position, a first clearance is formed between the bottom of the first outer cap and the intermediate cover.
[0019] In some embodiments, an inner diameter of the powder outlet nozzle is smaller than an inner diameter of the recessed region, such that a second clearance is formed between the powder outlet nozzle and the recessed region.
[0020] Other aspects and features of the present invention will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Unless defined otherwise, all other technical and scientific terms used herein have the same meaning as is commonly understood by a skilled person to which the subject matter herein belongs.EMBODIMENT 1
[0032] Referring to FIGS. 1 to 3, the present invention provides a flip-top foundation bottle, comprising a container body 1 , an intermediate cover 2, a powder outlet nozzle 3, a first outer cap 4, and a second outer cap 5. The container body 1 is configured to contain foundation. In the present embodiment, the container body 1 , the first outer cap 4, and the second outer cap 5 are all configured in an overall square shape, which facilitates squeezing out the foundation. Of course, in other embodiments, other shapes may be selected. In certain embodiments, the foundation bottle of the present application may omit the second outer cap.
[0033] A first opening 1 1 is formed at the center of the top of the container body 1 fordispensing foundation. A boss 12 is disposed between the first opening 1 1 and the main body of the container body 1 , and a locking groove 13 is provided on a side surface of the boss 12 for connection with the intermediate cover 2.
[0034] In some embodiments, the intermediate cover 2 is configured to have an external shape matching that of the boss 12. A cavity 21 is formed on the bottom surface of the intermediate cover 2, which matches the shape of the boss 12 and whose outer edges conform to the profile of the container body 1 . Four locking members 22 are formed along the edge of the cavity 21 for fixed engagement with the locking groove 13. During assembly, the intermediate cover 2 can be fixedly mounted onto the container body 1 by applying external pressure to engage the locking members 22 with the locking groove 13.
[0035] In some embodiments, the boss is configured as a raised annular ring or cylindrical protrusion that helps align or secure the intermediate cover 2 onto the container body. Its locking groove interacts with a corresponding locking member on the intermediate cover 2 to ensure stable attachment and prevent loosening.
[0036] Once the intermediate cover 2 is assembled to the container body 1 , a second opening 23 formed at the center of the top of the intermediate cover 2 has an inner diameter substantially equal to the outer diameter of the first opening 1 1. The second opening 23 is of the same height as the first opening 1 1 and covers the outer side of the first opening 11 , with their top surfaces flush.
[0037] The powder outlet nozzle 3 is made of silicone or rubber and includes a lower insertion portion 31 , a middle sealing ring portion 32, and an upper powder-dispensing portion 33. The surface of the insertion portion 31 is provided with a plurality of protruding rings 311 that snugly engage the inner wall of the first opening 11 to fix and seal the nozzle. The outer diameter of the sealing ring portion 32 is approximately equal to the outer diameter of the second opening 23 and is configured to seal the gap between the first opening 1 1 and the second opening 23. The sealing ring portion 32 simultaneously seals both the first and second openings to prevent foundation from adhering to the interstitial space during extrusion. The powder-dispensing portion 33 is formed as a tapered structure. When the first outer cap 4 is flipped closed over the intermediate cover 2, a sealing post 41 disposed at the center of the first outer cap 4 is snugly inserted into the center of the powder-dispensing portion, i.e., the powder-dispensing channel.
[0038] In other words, the sealing ring portion 32 cooperates with both the first opening 1 1 and the second opening 23 to form a double-sealing structure. Specifically, the sealing ring portion 32 tightly abuts the first opening 1 1 to seal its edge. Even if a small amount of foundation inadvertently seeps from the first opening 1 1 , it will preferentially enter the gap between the first and second openings rather than flowing directly down the outer wall of the second opening 23.
[0039] A recessed region 42 is formed on the bottom surface of the first outer cap 4 and is configured to accommodate the second opening 23 and the powder outlet nozzle 3. The sealing post 41 is disposed at the center of the recessed region 42.
[0040] One side of the intermediate cover 2 is provided with a locking position 24, and the other side is formed with a mounting seat 25 for rotatable connection with the second outer cap 5. A hook portion 43 is formed on one side of the first outer cap 4 to engage the locking position 24 at the edge of the intermediate cover 2, thereby securing the first outer cap 4 in a closed position over the intermediate cover 2.
[0041] The first outer cap 4 is fixedly retained within the second outer cap 5 via a second locking position 44. The edge of an opening of the second outer cap 5 is formed with a notch portion 51 that corresponds in shape to the mounting seat 25. The notch portion 51 and the mounting seat 25 are each provided with a hinge hole 52, and the two components are flip-connected by inserting a hinge shaft 53.
[0042] In the present disclosure, the locking position 24 is also referred to as the first locking position 24, and the locking position 44 is also referred to as the second locking position 44.
[0043] In some embodiments, at least one limiting protrusion 54 is disposed inside the second outer cap 5. When the first outer cap 4 is fixed within the second outer cap 5, a top portion of the first outer cap 4 abuts against the limiting protrusion 54.
[0044] In certain embodiments, a plurality of reinforcement ribs 55 are circumferentially disposed along a sidewall of the first outer cap 4. When the first outer cap 4 is fixed within the second outer cap 5, the reinforcement ribs 55 press against an inner wall of the second outer cap 5 to enhance the connection strength between the two components and prevent unintended detachment of the first outer cap 4 from the second outer cap 5 during the opening and closing operations.
[0045] In other embodiments, the first outer cap 4 may be integrally formed with the second outer cap 5 or fixedly connected thereto by other means.
[0046] In some embodiments, an edge of the opening of the second outer cap 5 abuts against an outer edge of the top surface of the intermediate cover 2, thereby ensuring structural stability of the capping assembly formed by the first outer cap 4 and the second outer cap 5, while maintaining an integrated appearance. Through the combined configuration of the inner and outer first and second outer caps (4 and 5), the overall flip- top structure is made more robust, less prone to damaging the sealing structure, and capable of achieving a longer structural service life and more reliable sealing.
[0047] Furthermore, as the edge of the second outer cap 5 abuts against the outer edge of the top of the intermediate cover 2, an enclosed space is formed inside the first outer cap 4. This helps prevent air from entering the recessed region inside the first outer cap 4, thereby avoiding accidental overflow from the powder-dispensing portion 33, as well as oxidation or drying of foundation residue remaining on the top of the powderdispensing portion 33 due to air exposure.EMBODIMENT 2
[0048] Different from Embodiment 1 , the foundation bottle of the present embodiment further comprises the following structural features:
[0049] In some embodiments, the powder-dispensing portion 33 is provided with a contact portion 331 configured to cooperate with a bottom surface of the first outer cap 4. When the first outer cap 4 is closed onto the intermediate cover 2, the sealing post 41 is snugly inserted into the powder-dispensing portion 33, and the bottom surface of the first outer cap 4 abuts the contact portion 331 . When a user presses downward on the flip-top (i.e., the first outer cap 4 or the combination of the first outer cap 4 and the second outer cap 5), the applied force is transmitted through the contact portion 331 , thereby pressing the powder outlet nozzle 3 downward. As a result, the sealing ring portion 32 is tightly compressed against both the first opening 11 and the second opening 23 to enhance sealing performance.
[0050] Even if loosening occurs between the intermediate cover 2 and the container body (e.g., in households with young children or toddlers who may repeatedly open and close the flip-top cap by imitating adult behaviour, or who may apply excessive force,such as by striking or pressing on the flip-top cap beyond its designed load capacity, such actions may result in deformation of the sealing post 41 , the flip-top action can still reestablish a tight connection between the intermediate cover 2 and the container body upon reclosing. In some embodiments, the flip-top cap may comprise the first outer cap, or both the first and second outer caps.
[0051] In some embodiments, a powder outlet 332 is formed at a top of the powderdispensing portion 33, and the inner diameter of the powder outlet 332 gradually decreases from top to bottom to form a guiding slope 333. The contact portion 331 is arranged circumferentially along the top of the powder outlet 332. When the flip-top is closed onto the intermediate cover 2, the sealing post 41 is guided into the powderdispensing portion 33 by the guiding slope 333. Even if the sealing post 41 becomes worn or deformed during long-term use, it can still be smoothly inserted into the center of the powder-dispensing portion 33 to achieve sealing.
[0052] Additionally, after dispensing foundation, any residual foundation may flow back into the container body along the guiding slope 333, thereby reducing residue buildup at the top of the powder-dispensing portion. The contact portion 331 forms a peripheral barrier around the powder outlet 332 to seal the outlet and further enhance sealing performance.
[0053] In some embodiments, a spacer 45 is disposed between the hook portion 43 and the bottom of the first outer cap 4. When the hook portion 43 is engaged with the first locking position 24, a first clearance 61 is formed between the bottom of the first outer cap 4 and the intermediate cover2. The first clearance 61 essentially refers to a functional spacing or gap intentionally formed between the first outer cap 4 and the intermediate cover 2 to permit or accommodate motion, such as compression, resealing. The first clearance 61 is configured to allow relative movement during the flip-top opening and closing process, especially when the hook portion 43 engages or disengages from the locking position 24: it provides structural flexibility to accommodate slight shifts, pressing force, or deformation that may occur during use. Moreover, the first clearance 61 is operable to enable the first outer cap 4 to apply downward pressure on the powder outlet nozzle 3 through the contact portion when closing, thereby enhancing sealing reliability at both the first opening 11 and second opening 23.
[0054] The inner diameter of the powder outlet nozzle 3 is smaller than the innerdiameter of the recessed region 42, such that a second clearance 62 is formed between the powder outlet nozzle 3 and the recessed region 42. The second clearance 62 essentially refers to a functional spacing or gap intentionally formed between the powder outlet nozzle 3 and the recessed region 42 of the first outer cap 4. The second clearance 62 is configured to accommodate relative movement between the two components during the opening and closing of the first outer cap 4: it allows the powder outlet nozzle 3 to be pressed downward when the first outer cap 4 is closed, thereby enhancing the sealing pressure applied by the sealing ring portion. Additionally, the second clearance 62 is configured to provide tolerance compensation, enabling adaptive alignment even if minor deformation or wear occurs over time, such as from repeated use or external force.
[0055] In other words, contact between the first outer cap 4 and the powder outlet nozzle 3 occurs only at the contact portion 331 , and contact between the first outer cap 4 and the intermediate cover 2 occurs only at the hook portion 43. During the process of opening the flip-top, the hook portion 43 first disengages from the first locking position 24. The first outer cap 4 detaches from part of the powder outlet nozzle 3, while the other part (on the side near the hinge hole 52) of the powder outlet nozzle 3 is compressed, allowing the flip-top to rotate smoothly about the hinge shaft 53 without obstruction.
[0056] In summary, the present application provides a flip-top foundation bottle with clearance-based adaptiveness and guided anti-leakage features. This design improves user convenience while effectively maintaining sealing performance. Specifically, the dual-clearance structure (first clearance + second clearance) and the guiding slope enable dynamic adaptiveness of the flip-top (i.e., the first outer cap, or the first and second outer caps) during the opening and closing process. At the same time, the force transmission mechanism via the contact portion ensures long-term reliable sealing between the sealing post and the powder-dispensing portion.
[0057] In details, the present invention achieves the following technical effects and advantages: with the structural improvements described above, the present application enables the foundation bottle to be opened and closed in a flip-top manner. The opening and closing operations can be performed through simple user actions, thereby significantly improving the user experience. At the same time, the sealing structure between the flip-top cap and the bottle body is optimized to ensure the stability and safety of the foundation during storage and use. Moreover, the present application also takesinto account the durability of the flip-top cap and extends its service life through a well- considered structural design.
[0058] In other words, the present application provides an adaptive flip-top foundation bottle featuring anti-leakage guidance and functional clearance. It not only enhances the convenience of use but also effectively ensures sealing performance. Specifically, through the use of dual clearance structures (a first clearance and a second clearance) and a guiding slope configuration, the flip-top cap (which may comprise the first outer cap, or the first and second outer caps) achieves dynamic adaptiveness during the opening and closing process, thereby improving operational ease. Simultaneously, a force transmission mechanism via a contact portion ensures long-term reliable sealing between the sealing post and the powder-dispensing portion, and between the intermediate cover and the container body.
[0059] In a foundation bottle having the above structure, when the flip-top cap is opened, a hook portion first disengages from a first locking position, causing part of the powder outlet nozzle to detach from the first outer cap, while the other portion (on the side near the hinge hole) of the nozzle is compressed, allowing the flip-top cap to rotate smoothly about the hinge axis. When the flip-top cap is closed, the sealing post is guided into the powder-dispensing portion by the guiding slope and is constrained therein, enabling an “adaptive" adjustment of the sealing post. Even if the sealing post becomes worn or deformed after prolonged use (for instance, in households with children in an exploratory stage, where the flip-top may be forcefully struck or sat on beyond the designed load, leading to deformation of the sealing post), the sealing post can still be reliably inserted into the center of the powder-dispensing portion to achieve sealing. Furthermore, the force applied to the flip-top cap is transmitted via the contact portion to compress the powder outlet nozzle downward, thereby ensuring that the sealing ring portion is tightly pressed against both the first and second openings for improved sealing.
[0060] Additionally, even if loosening occurs between the intermediate cover and the container body (such as in households with young children who may repeatedly open and close the cap by imitating adult behaviors, causing looseness), the process of reclosing the flip-top cap can re-tighten the connection between the intermediate cover and the container body. This achieves an “adaptive” adjustment between the flip-top cap and the container body.
[0061] It should be further appreciated by the person skilled in the art that variations and combinations of features described above, not being alternatives or substitutes, may be combined to form yet further embodiments falling within the intended scope of the invention. As would be understood by a person skilled in the art, each embodiment, may be used in combination with other embodiment or several embodiments.
