Description

Technical Field

[0001] This utility model belongs to the field of packaging bottle technology, specifically a bottle cap assembly for preventing exposure and dispensing quantitative materials. Background Technology

[0002] Cosmetic packaging containers are not only the carriers of product contents, but also a crucial element in ensuring product efficacy, user experience, and brand value. In recent years, with the popularization of functional cosmetics and the concept of precision skincare, the shortcomings of traditional packaging caps in terms of sealing and quantitative dispensing have become increasingly prominent, becoming a significant bottleneck restricting product quality and user satisfaction.

[0003] The existing technology mainly suffers from the following core problems: I. Oxidation and Contamination Issues Caused by Content Exposure: Traditional screw-on or push-button caps expose the contents directly to the air after opening, leading to two major risks: 1. Oxidation and Deactivation of Active Ingredients: Contact between oxygen in the air and the contents accelerates their decomposition, significantly reducing product efficacy. 2. Microbial and Dust Contamination: During repeated opening and closing, bacteria and dust from the environment can easily enter the bottle, contaminating the remaining contents, causing spoilage, and even triggering skin allergies.

[0004] Existing improvements such as pump heads or duckbill valves can partially isolate air, but their structures still have gas backflow channels, which cannot completely block the oxidation path. Furthermore, the complex structure increases costs and failure rates.

[0005] Second, the pain point of insufficient quantitative dispensing accuracy: functional cosmetics need to strictly follow the single dosage, but traditional bottle caps are difficult to control precisely. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing an anti-exposure quantitative dispensing bottle cap assembly. This bottle cap assembly can prevent the contents from being exposed to the air and can accurately dispense the contents.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an anti-exposure quantitative dispensing bottle cap assembly, comprising a fixing component that can be fixed to the bottle mouth and a rotating component rotatably connected to the fixing component. The fixing component is provided with a volume-fixing cavity, which has a first opening communicating with the inside of the bottle and a second opening communicating with the outside. The rotating component includes a first baffle for closing the first opening and a second baffle for closing the second opening. The first baffle has a first flow port that can rotate with the rotating component relative to the fixing component to align with the first opening. The second baffle has a second flow port that can rotate with the rotating component relative to the fixing component to align with the second opening. The rotating component is positioned such that both the first opening and the second opening of the volume-fixing cavity are closed. With the rotation of the rotating component, at most one of the first opening and the second opening is opened. When using this anti-exposure quantitative dispensing bottle cap assembly, rotating the rotating assembly aligns the first flow port with the first opening. Inverting the bottle allows the contents to be loaded into the volumetric cavity. Rotating the rotating assembly then seals both the first and second openings, storing the contents quantitatively within the volumetric cavity. Continuing to rotate the rotating assembly aligns the second flow port with the second opening allows the contents to be poured out from the second opening, thus preventing the contents from being exposed to air and enabling precise quantitative dispensing.

[0008] In the above technical solution, preferably, the fixing component includes an outer sleeve, and a partition is disposed inside the outer sleeve. The partition has a raised wall surrounding the cavity forming the fixed volume cavity. This structure facilitates the formation of the fixed volume cavity.

[0009] In the above technical solution, preferably, the inner wall of the outer component is provided with a limiting rib, and the outer wall of the partition is provided with a limiting groove. The limiting rib engages with the limiting groove to position the partition. This structure facilitates the production and assembly of the fixing components.

[0010] In the above technical solution, preferably, the partition plate is provided with a connecting hole, and the first baffle and the second baffle are connected by a connecting structure passing through the connecting hole. This structure facilitates the connection of the first baffle and the second baffle, and allows the first baffle and the second baffle to rotate as a whole.

[0011] In the above technical solution, preferably, the connection structure includes an insertion portion disposed on the first baffle and an insertion groove disposed on the second baffle. The sidewall of the insertion groove is provided with a limiting hole, and the sidewall of the insertion portion is provided with a limiting protrusion for insertion into the limiting hole. This connection structure further facilitates the connection between the first baffle and the second baffle.

[0012] In the above technical solution, preferably, the limiting protrusion is wedge-shaped. This structure further facilitates the insertion and positioning of the connector into the connector slot.

[0013] In the above technical solution, preferably, a cylindrical sealing body is fitted and matched to the inner wall of the volume-fixing cavity, and one end of the cylindrical sealing body abuts against the first baffle. This structure can prevent liquid or air leakage through the gap between the first baffle and the volume-fixing cavity, thereby affecting the accuracy of quantitative measurement and preventing the contents from being exposed.

[0014] In the above technical solution, preferably, the other end of the cylindrical sealing body abuts against the second baffle. This structure can prevent leakage from the gap between the second baffle and the fixed-volume cavity.

[0015] In the above technical solution, preferably, an annular sealing body is provided on the outer side of the connecting structure, and the annular sealing body is sandwiched between the first baffle and the outer edge of the connecting hole. This structure avoids liquid or air leakage at the connecting hole, thereby preventing the contents from being exposed.

[0016] In the above technical solution, preferably, the fixed component is provided with a plurality of fixed-volume cavities around the rotation center of the rotating component, the first baffle is provided with a plurality of first openings corresponding to the plurality of fixed-volume cavities, the second baffle is provided with a plurality of second openings corresponding to the plurality of fixed-volume cavities, and the bottom of the second baffle is provided with a positioning protrusion located outside the fixed-volume cavity. When the positioning protrusion contacts the outer wall of the fixed-volume cavity on one side, the first flow port is aligned with the first opening, and when the positioning protrusion contacts the outer wall of the fixed-volume cavity on the other side, the first flow port is offset from the first opening.

[0017] Compared with the prior art, this utility model has the following advantages: When using this anti-exposure quantitative dispensing bottle cap assembly, by rotating the rotating assembly to align the first flow port with the first opening, the bottle body can be inverted to load the contents into the fixed volume chamber. Then, by rotating the rotating assembly to close both the first and second openings, the contents are quantitatively stored in the fixed volume chamber. Afterward, by continuing to rotate the rotating assembly to align the second flow port with the second opening, the contents can be poured out from the second opening for use, thereby avoiding the contents being exposed to the air and enabling precise quantitative dispensing.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 4 An anti-exposure dispensing bottle cap assembly includes a fixing component 1 that can be fixed to the bottle mouth of a bottle body 100 and a rotating component 2 that is rotatably connected to the fixing component 1. In this embodiment, the fixing component 1 and the bottle mouth are locked together. Of course, in other embodiments, other existing fitting and installation methods such as threaded fitting can also be used. Both the inner wall of the fixing component 1 and the outer wall of the rotating component 2 are provided with annular protrusions. The two annular protrusions are engaged to prevent the fixing component 1 and the rotating component 2 from separating and to achieve relative rotation. The fixing component 1 is provided with a volume-fixing cavity 3, which has a first opening 4 communicating with the interior of the bottle body 100. The rotating assembly 2 includes a first baffle 6 for closing the first opening 4 and a second baffle 7 for closing the second opening 5. The first baffle 6 has a first flow port 8 that can rotate with the rotating assembly 2 relative to the fixed assembly 1 to align with the first opening 4. The second baffle 7 has a second flow port 9 that can rotate with the rotating assembly 2 relative to the fixed assembly 1 to align with the second opening 5. The rotating assembly 2 has a position where both the first opening 4 and the second opening 5 of the fixed cavity 3 are closed. As the rotating assembly 2 rotates, at most one of the first opening 4 and the second opening 5 is opened. When using this anti-exposure quantitative dispensing bottle cap assembly, rotating the rotating component 2 aligns the first flow port 8 with the first opening 4. Inverting the bottle body 100 allows the contents of the bottle body 100 to be loaded into the volume-fixing cavity 3. Then, rotating the rotating component 2 closes both the first opening 4 and the second opening 5, at which point the contents are quantitatively stored in the volume-fixing cavity 3. Afterward, rotating the rotating component 2 again aligns the second flow port 9 with the second opening 5, allowing the contents to be poured out from the second opening 5 for use. This avoids the contents being exposed to the air and enables precise quantitative dispensing.

[0023] In this embodiment, the fixing component 1 includes an outer sleeve 10, and a partition 11 is disposed inside the outer sleeve 10. The partition 11 is provided with a protruding wall 12 surrounding the cavity 3. This structure facilitates the formation of the cavity 3.

[0024] In this embodiment, the inner wall of the outer sleeve 10 is provided with a limiting rib 13, and the outer wall of the partition 11 is provided with a limiting groove 14. The limiting rib 13 engages with the limiting groove 14 to position the partition 11. This structure facilitates the production and assembly of the fixing component 1. Of course, in other embodiments, the outer sleeve 10 and the partition 11 can also be integrally formed.

[0025] In this embodiment, the partition 11 is provided with a connecting hole 15, and the first baffle 6 and the second baffle 7 are connected by a connecting structure 16 passing through the connecting hole 15. This structure facilitates the connection of the first baffle 6 and the second baffle 7, and allows the first baffle 6 and the second baffle 7 to rotate as a whole. In this embodiment, the connecting hole 15 is located at the center of the partition 11, and there is only one hole. The first baffle 6 and the second baffle 7 are connected by a single connecting structure 16.

[0026] It will be readily understood by those skilled in the art that in other embodiments, in order to achieve the connection and rotation of the first baffle 6 and the second baffle 7, the connecting hole may also be one or more arc-shaped holes provided on the partition 11 around the rotation center. The first baffle 6 and the second baffle 7 are still connected by the connecting structure 16 passing through the connecting hole, which can also achieve the purpose of the first baffle 6 and the second baffle 7 rotating relative to the fixed component 1 at the same time.

[0027] In this embodiment, the connecting structure 16 includes a plug-in portion 17 disposed on the first baffle 6 and a plug-in groove 18 disposed on the second baffle 7. The side wall of the plug-in groove 18 is provided with a limiting hole 19, and the side wall of the plug-in portion 17 is provided with a limiting protrusion 20 for inserting into the limiting hole 19. This connecting structure 16 further facilitates the connection between the first baffle 6 and the second baffle 7.

[0028] In this embodiment, the limiting protrusion 20 is wedge-shaped. This structure further facilitates the insertion and positioning of the connector 17 into the connector slot 18.

[0029] In this embodiment, a cylindrical sealing body 21 is fitted and matched to the inner wall of the volume-fixing cavity 3, with one end of the cylindrical sealing body 21 abutting against the first baffle 6. This structure can prevent liquid or air leakage from the gap between the first baffle 6 and the volume-fixing cavity 3, thereby affecting the accuracy of quantitative measurement and preventing the contents from being exposed.

[0030] In this embodiment, the other end of the cylindrical sealing body 21 abuts against the second baffle 7. This structure can prevent leakage from the gap between the second baffle 7 and the fixed-volume cavity 3.

[0031] In this embodiment, an annular sealing body 22 is provided on the outer side of the connecting structure 16, and the annular sealing body 22 is sandwiched between the first baffle 6 and the outer edge of the connecting hole 15. This structure avoids liquid or air leakage at the connecting hole 15, thereby preventing the contents from being exposed.

[0032] In this embodiment, the cylindrical sealing body 21 and the annular sealing body 22 are connected as one unit. This facilitates assembly and also makes it easier to position the annular sealing body 22, preventing displacement.

[0033] The fixed component 1 has a plurality of fixed-volume cavities 3 arranged around the rotation center of the rotating component 2. The first baffle 6 has a plurality of first openings 4 that correspond one-to-one with the plurality of fixed-volume cavities 3, and the second baffle 7 has a plurality of second openings 5 ​​that correspond one-to-one with the plurality of fixed-volume cavities 3. In this embodiment, the fixed component 1 has two evenly distributed fixed-volume cavities 3 arranged around the rotation center of the rotating component 2. The first baffle 6 has two first openings 4 that correspond one-to-one with the two fixed-volume cavities 3, and the second baffle 7 has two second openings 5 ​​that correspond one-to-one with the two fixed-volume cavities 3.

[0034] It will be readily understood by those skilled in the art that, in other embodiments, the fixed component 1 may have more fixed-volume cavities 3 around the rotation center of the rotating component 2.

[0035] In this embodiment, since the position of the first flow port 8 is not visible, it is impossible to confirm whether the first flow port 8 is aligned with the first opening 4. To facilitate the positioning of the first flow port 8, the bottom of the second baffle 7 is also provided with a positioning protrusion 23. The positioning protrusion 23 is located on the outside of the fixed volume cavity 3 and can contact the outer wall of the fixed volume cavity 3 during the rotation of the second baffle 7 to position the rotational position of the first opening 4. When the positioning protrusion 23 contacts the outer wall of the fixed volume cavity 3 on one side, the first flow port 8 is aligned with the first opening 4. When the positioning protrusion 23 contacts the outer wall of the fixed volume cavity 3 on the other side, the first flow port 8 is misaligned with the first opening 4.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
