Description

Technical Field

[0001] This utility model relates to the field of hair dye storage and transportation technology, specifically to a leak-proof cotton core sleeve assembly. Background Technology

[0002] In current hair dyeing techniques, a common method is to use specific hair dyeing tools to achieve the desired effect. These tools mainly consist of a water-dispensing nylon wand, an absorbent cotton core, and a nylon nozzle.

[0003] The absorbent cotton wick, a key component for storing hair dye liquid, is typically pre-soaked in the prepared hair dye solution to fully absorb and store a large amount of the liquid. When the hair dyeing process is needed, a specially designed water-dispensing nylon stick is inserted into the absorbent cotton wick, which is already saturated with hair dye liquid. Due to the excellent water absorption and conductivity of the nylon stick, the hair dye liquid in the wick gradually permeates along the pore structure of the nylon stick and is absorbed onto its surface through capillary action.

[0004] Then, the nylon wand, soaked in hair dye, is extended through the nylon tip of the tool. In actual use, the consumer simply holds the tool and brings the nylon wand into contact with the section of hair to be dyed. Upon contact, the hair dye absorbed by the nylon wand is transferred to the hair surface. By continuously moving the nylon wand, it is ensured that each strand of hair is fully exposed to the dye, thus achieving the goal of evenly coating the hair surface and completing the hair dyeing process.

[0005] However, the following problems exist when the hair dye is soaked in the prepared solution during transportation:

[0006] Leakage issue: During transport, if the container is dropped or shaken, the liquid inside the cotton wick may be flung out due to inertia and leak through the large-diameter vent (usually ≥1.5mm), contaminating the outside of the bottle.

[0007] Insufficient sealing: The gap between the nylon rod and the mounting hole is too large (>0.5mm), and the components of the container are only connected by a single-stage snap-fit, making it easy for liquid to seep out along the gap.

[0008] Liquid retention: Leaked liquid accumulates in the cap or shoulder cover and cannot flow back, resulting in permanent contamination.

[0009] These issues severely limit the e-commerce application of hair dye products. Utility Model Content

[0010] Therefore, this utility model provides a leak-proof cotton core sleeve assembly to solve the above-mentioned problems in the prior art.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] According to a first aspect of the present invention, a leak-proof cotton core sleeve assembly includes a cotton core sleeve body, a shoulder sleeve, and a bottle body.

[0013] The cotton core sleeve body is provided with at least one set of water guiding units. The water guiding unit includes a water guiding hole and a set of venting holes. The water guiding hole is axially through the cotton core sleeve body. The diameter of the water guiding hole is adapted to the outer diameter of the water guiding component. The water guiding component passes through the water guiding hole. The venting hole sets are symmetrically distributed on both sides of the water guiding hole. Each venting hole set contains at least two micropores with a diameter of 0.8-1.2 mm.

[0014] The cotton core sleeve body fits into the shoulder sleeve to form a first sealed chamber, and the shoulder sleeve fits into the bottle body to form a second sealed chamber, together forming a multi-level leak-proof structure.

[0015] Furthermore, the water guide holes are arranged in a linear array on the cotton core sleeve body, with four holes respectively positioned between the two sets of air vent groups.

[0016] Furthermore, each of the vent hole groups comprises three circular holes with a diameter of 1±0.05mm, and the ratio of their total cross-sectional area to the cross-sectional area of ​​the corresponding water guide hole is 1:15-1:20.

[0017] Furthermore, the first sealed chamber adopts an interference fit structure, the upper end of the cotton core sleeve body is provided with an annular flange, and the lower end of the shoulder sleeve is provided with a matching annular groove.

[0018] Furthermore, the second sealed chamber adopts a threaded connection structure, the inner wall of the shoulder sleeve is provided with internal threads, and the bottle opening is provided with a matching external thread.

[0019] Furthermore, the water guiding component is a nylon rod with a microgroove structure on its surface, and its lower end extends into the absorbent cotton core inside the bottle body.

[0020] Furthermore, the shoulder sleeve has at least one positioning hole, the diameter of which is the same as that of the water guide hole, and the positioning hole and the water guide hole are coaxially arranged. The end of the water guide component away from the water guide hole passes through the positioning hole.

[0021] Furthermore, the shoulder sleeve is provided with a partition plate, and the partition plate is fixedly disposed on the side of the positioning hole.

[0022] Furthermore, it also includes a bottle cap, the bottom of which has a snap-fit ​​groove, and the outer wall of the shoulder sleeve has a matching snap-fit ​​protrusion, which is detachably snapped into the snap-fit ​​groove.

[0023] Furthermore, two snap-fit ​​grooves are symmetrically arranged at the bottom of the bottle cap, and two snap-fit ​​protrusions are symmetrically arranged on both sides of the outer wall of the shoulder sleeve, with each snap-fit ​​groove and each snap-fit ​​protrusion corresponding to one another.

[0024] This utility model has the following advantages:

[0025] In this invention, the water-guiding unit of the cotton core sleeve body features water-guiding holes that are compatible with the water-guiding components, ensuring stable installation of the components and allowing liquid to flow smoothly through them, meeting the liquid transfer requirements during normal use. Vent holes are symmetrically distributed on both sides of the water-guiding holes, and each vent hole group contains micropores of a specific diameter. During liquid discharge, these micropores balance internal and external air pressure, preventing abnormal liquid outflow due to pressure differences. Simultaneously, the small pore size of the micropores prevents liquid from flowing directly out of the vent holes, reducing the risk of leakage.

[0026] The cotton wick sleeve and shoulder sleeve fit together to form a first sealed chamber, while the shoulder sleeve fits together with the bottle body to form a second sealed chamber, creating a multi-level leak-proof structure. During transportation, even if subjected to external forces such as vibration, bumps, or drops, the first sealed chamber can block some of the liquid that may leak; if liquid still breaks through the first sealed chamber, the second sealed chamber can further intercept it. This multi-level protection significantly reduces the probability of liquid leaking from the container to the outside.

[0027] By combining a water-guiding unit and a multi-stage sealing structure, this leak-proof cotton core sleeve assembly ensures stable and smooth liquid drainage during normal use, meeting practical functional requirements, while also providing reliable leak-proof protection during non-use stages such as transportation. This not only enhances product reliability and stability but also improves the user experience, reduces inconvenience caused by liquid leaks, and helps improve the product's market competitiveness.

[0040] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] like Figures 1 to 8As shown, a leak-proof cotton core sleeve assembly in the first aspect embodiment of this utility model includes a cotton core sleeve body 1, a shoulder sleeve 2, a bottle body 3, a water guiding component 4, an absorbent cotton core 5, and a bottle cap 6.

[0042] The cotton core sleeve body 1 is provided with four sets of water guiding units. Each set of water guiding units includes a water guiding hole 11 and a set of vent holes 12. The water guiding hole 11 is axially through the cotton core sleeve body 1, and the diameter of the water guiding hole 11 is adapted to the outer diameter of the water guiding component 4. The water guiding component 4 passes through the water guiding hole 11. The vent holes 12 are symmetrically distributed on both sides of the water guiding hole 11. Each vent hole set 12 contains at least two micropores with a diameter of 1.0±0.02mm, preferably 1mm. The cotton core sleeve body 1 fits with the shoulder sleeve 2 to form a first sealed chamber, and the shoulder sleeve 2 fits with the bottle body 3 to form a second sealed chamber, together constituting a multi-level leak-proof structure.

[0043] To use, first pour the prepared hair dye solution into the bottle, then soak the absorbent cotton core in the solution to fully absorb and store a large amount of dye. Pass the water-guiding component through the water-guiding hole in the cotton core sleeve, ensuring the lower end of the component contacts the absorbent cotton core inside the bottle. Then, assemble the cotton core sleeve with the shoulder cover, and finally, assemble the shoulder cover with the bottle to complete the assembly.

[0044] This invention, by setting up a water guiding unit, ensures a reasonable layout of the liquid transmission channel and the air pressure balance channel. The multi-level anti-leakage structure design can effectively prevent liquid from leaking from the container during transportation or use, thereby improving the product's sealing performance and reliability.

[0045] Adjacent water guide holes 11 are evenly arranged in a linear array with a spacing of 5mm on the cotton core sleeve body 1. There are four of them, which are respectively set between the two groups of vent holes 12. The water guide holes are evenly arranged in a linear array and the number is fixed, which makes the distribution of water guide components more reasonable. Each water guide component can discharge liquid from the bottle body 3, which improves the stability and uniformity of liquid discharge.

[0046] Each vent assembly 12 contains three circular holes with a diameter of 1±0.05mm. The ratio of their total cross-sectional area to the cross-sectional area of ​​the corresponding water guide hole 11 is 1:15-1:20. The determined specifications of the circular holes in the vent assembly and their ratio to the cross-sectional area of ​​the water guide hole can more accurately balance the air pressure, ensuring smooth liquid discharge and effectively preventing liquid leakage from the vent holes, thus further improving the leak-proof performance.

[0047] The first sealing chamber adopts an interference fit structure. The upper end of the cotton core sleeve body 1 is provided with an annular flange 13, and the lower end of the shoulder sleeve 2 is provided with a matching annular groove 21. The interference fit structure of the first sealing chamber is easy to install and provides good sealing performance. In the multi-stage leak-proof structure, it plays a preliminary role in blocking liquid leakage and enhances the overall leak-proof capability. The second sealing chamber adopts a threaded connection structure. The inner wall of the shoulder sleeve 2 is provided with an internal thread 22, and the opening of the bottle body 3 is provided with a matching external thread 31. The threaded connection structure of the second sealing chamber is firmly connected and has a good sealing effect, which can effectively prevent liquid from leaking from the connection between the bottle body and the shoulder sleeve, further strengthening the protective effect of the multi-stage leak-proof structure.

[0048] The water guiding component 4 is a nylon rod with a microgroove structure on its surface (not shown in the figure). Its lower end extends into the absorbent cotton core 5 inside the bottle body 3. The microgroove structure on the surface of the nylon rod increases the contact area with the liquid, which is conducive to the adsorption and transmission of the liquid. It can more smoothly guide the liquid out of the absorbent cotton core inside the bottle body, improving the convenience of use.

[0049] The shoulder sleeve 2 has at least one positioning hole 23. The diameter of the positioning hole 23 is the same as that of the water guide hole 11, and the positioning hole 23 and the water guide hole 11 are coaxially arranged. The end of the water guide component 4 away from the water guide hole 11 passes through the positioning hole 23. The positioning hole provides further positioning and support for the water guide component, preventing it from shaking or shifting during use, ensuring the stability of liquid transmission, and also helping to improve the reliability of the overall structure. At the same time, the shoulder sleeve 2 is provided with a partition plate 24, which is fixedly set on the side of the positioning hole 23, and can separate the water guide components on different water guide holes 11.

[0050] The bottle cap 6 has a snap-fit ​​groove 601 at its bottom, and the outer wall of the shoulder sleeve 2 has a matching snap-fit ​​protrusion 25. The snap-fit ​​protrusion 25 is detachably engaged in the snap-fit ​​groove 601. Align the snap-fit ​​groove on the bottom of the bottle cap with the snap-fit ​​protrusion on the outer wall of the shoulder sleeve, and press down to engage the snap-fit ​​protrusion in the snap-fit ​​groove. The snap-fit ​​structure facilitates the installation and removal of the bottle cap. When not in use, it can effectively seal the components, preventing dust and other impurities from entering, and also helps to prevent leakage to a certain extent, protecting the internal liquid. Two snap-fit ​​grooves 601 are symmetrically arranged at the bottom of the bottle cap 6, and two snap-fit ​​protrusions 25 are symmetrically arranged on both sides of the outer wall of the shoulder sleeve 2. Each snap-fit ​​groove 601 and each snap-fit ​​protrusion 25 are arranged one-to-one. When installing the bottle cap, ensure that the two snap-fit ​​grooves on the bottom of the bottle cap are engaged one-to-one with the two snap-fit ​​protrusions on both sides of the outer wall of the shoulder sleeve. The symmetrically arranged snap-fit ​​grooves and snap-fit ​​protrusions make the connection between the bottle cap and the shoulder sleeve more stable and balanced, avoiding problems such as poor sealing caused by uneven connection, and improving the overall sealing performance and appearance symmetry.

[0051] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
