Description

Technical Field

[0001] This utility model relates to the field of compressed towel technology, specifically a compressed towel liquid filling packaging box. Background Technology

[0002] Compressed towels, as a portable cleaning product, are manufactured using regular towels as raw materials. While fully preserving the original towel's quality, softness, and cleaning function, they undergo a secondary processing using professional compression technology. After compression, the towel's volume can be reduced by 80% to 90%, forming a compact block or sheet structure. During use, these compressed towels quickly expand back to their original shape and size upon contact with water, without damage or functional loss. Therefore, they greatly simplify the transportation, carrying, and storage of towels in travel, outdoor activities, business trips, and daily portability scenarios, effectively saving space and reducing carrying burden. They have become a widely used product type in modern convenient living.

[0003] As market demands for greater ease of use of compressed towels increase, individually packaged compressed towels with refillable solutions have gradually emerged. These products integrate the compressed towel with a refillable solution (such as purified water or cleaning solution) within the same package. Users no longer need to find an external water source; they simply press a button on the packaging to quickly wet the towel, further optimizing the usage process. This is especially suitable for scenarios where water is unavailable or difficult to access.

[0004] However, the existing single-piece liquid-dispensing compressed towels still have significant structural flaws, limiting their user experience and applicability: First, the liquid-dispensing mechanism in existing products is generally located in the middle or non-edge area of ​​the packaging, and is not designed for users who wear manicures. When users with manicures press the button, the raised shape or thickness of the manicure can interfere with the pressing mechanism, making it difficult to apply effective pressure and potentially causing damage or breakage of the manicure edges, resulting in inconvenience and additional losses for the user. Second, for small-sized single-piece products, due to the overall thinness of the product, the effective pressing area of ​​the existing pressing mechanism is small and insufficient in depth. Users cannot accurately align their fingers with the pressing point and apply sufficient pressure to make the pressing mechanism work properly, thus failing to trigger the release of the liquid and resulting in dispensing failure, affecting normal use. Third, although some existing products claim to achieve separation of the compressed towel and the liquid, the sealing and stability of the isolation structure are insufficient, making it prone to leakage during transportation or storage. This causes the compressed towel to become damp and deteriorate before use, reducing product reliability.

[0005] The problems existing in the above-mentioned prior art mean that the ease of use, applicable user coverage, and product reliability of single-piece liquid-adding compressed towels need to be improved, and they cannot fully meet the needs of different users (especially nail art users) and products of different sizes. Therefore, there is an urgent need for a liquid-adding packaging technology solution for compressed towels that can solve the above-mentioned pressing problem and ensure the dry and wet separation effect. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of existing products and provide a compressed towel liquid filling packaging box. This utility model effectively solves the problems of inconvenient pressing for nail technicians and insufficient pressing for small-sized products by setting the pressing part on the edge of the box and cooperating with the pressing notch, which significantly improves the convenience of use. At the same time, the independent receiving cavity ensures the dry and wet separation effect. The structure is simple and highly practical.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a compressed towel liquid filling packaging box, comprising:

[0008] The box body has a mutually isolated compressed towel receiving chamber and a liquid receiving chamber to achieve dry and wet separation of the compressed towel and the liquid;

[0009] A compressed towel, wherein the compressed towel is sealed in a compressed towel receiving cavity by a packaging film;

[0010] The solution is prepared and stored in the solution preparation container;

[0011] The pressing part is located on the edge area of ​​the box body and corresponds to the liquid dispensing cavity; the pressing notch is formed on the box body and is adapted to the outer edge of the pressing part, allowing the finger to apply force outward;

[0012] A conductive structure is provided between the compressed towel receiving cavity and the liquid receiving cavity, and is linked with the pressing part; when force is applied to the pressing part to make it flat, the conductive structure is opened, and the liquid in the liquid receiving cavity flows into the compressed towel receiving cavity through the conductive structure to add liquid and wet the compressed towel.

[0013] To further optimize this utility model, the following technical solutions may be preferred:

[0014] Preferably, the pressing part is a deformable base structure. The initial state of the base structure is convex, and it becomes flat after being pressed. The deformation process of the base structure drives the conduction structure to open.

[0015] Preferably, the isolation method between the compressed towel receiving cavity and the liquid receiving cavity is as follows: a sealing partition is provided inside the box body, the sealing partition constitutes the isolation boundary between the two chambers, and the conductive structure is provided on the sealing partition.

[0016] Preferably, the conductive structure is a preset break line or a one-way valve; when the pressing part is pressed flat, the preset break line breaks or the one-way valve opens, allowing the liquid to flow unidirectionally into the compressed towel receiving cavity.

[0017] Preferably, the pressing notch is arc-shaped or rectangular, and the depth of the pressing notch is not less than 1 / 2 of the wall thickness of the box, so as to accommodate the angle of finger application.

[0018] Preferably, the packaging film is a food-grade PE film or PET film, and the film is sealed and fitted to the edge of the cavity of the compressed towel receiving cavity to prevent the compressed towel from getting damp before use.

[0019] The beneficial effects of this utility model are mainly reflected in the following aspects:

[0020] (1) Solve the problem of pressing the button for nail technicians and improve the ease of use.

[0021] This invention places the pressing part on the edge of the box and provides a pressing notch. During use, the user can apply pressure outwards with their fingers, effectively preventing interference between the manicure (especially raised or long manicures) and the pressing structure. There's no need to worry about the manicure breaking or falling off due to friction during pressing, and pressure can be easily applied without additional adjustments to the application posture. This significantly improves the user experience for manicure wearers and fills a gap in existing products' suitability for this user group.

[0022] (2) Adaptable to small-sized and thin products, ensuring reliable liquid addition.

[0023] For small, thin single-piece products, the combined design of the edge pressing part and the pressing notch expands the reach of the effective force application area while reducing the dependence on pressing depth. Even if the overall thickness of the product is relatively thin, the user's finger can still accurately align with the pressing point and apply sufficient force to ensure that the pressing part can smoothly deform to trigger the conduction structure. This avoids the problem of "liquid dispensing failure due to insufficient pressing caused by the thinness of the product" in the existing technology, and ensures the reliability of liquid dispensing when using products of different sizes.

[0024] (3) Enhance the effect of dry and wet separation to ensure the stability of product storage and transportation.

[0025] The box features an independently isolated compressed towel compartment and a solution compartment, achieving physical isolation between the compressed towel and the solution. Combined with the sealed packaging film of the compressed towel, this effectively prevents leakage of the solution into the compressed towel compartment during storage and transportation, thus avoiding premature moisture absorption and deterioration of the compressed towel. Compared to some existing products with insufficient isolation and sealing, this invention significantly improves the product's shelf life and resistance to damage during transportation, ensuring the product's quality stability from manufacturing to use.

[0026] (4) The structure is simple and easy to implement, and it is both economical and practical.

[0027] The core optimization of this invention is achieved solely through a structural combination of "edge pressing part + pressing notch + double isolation chambers," eliminating the need for additional complex mechanical components or precision control structures. This simplifies the manufacturing process, keeps costs under control, and facilitates mass production. Furthermore, the overall structural design aligns with user habits, making it easy to operate and quick to learn, whether for everyday family use, travel, or outdoor activities. It combines economic efficiency with high practicality.

[0028] (5) Expand the scope of product application and improve market adaptability.

[0029] By addressing the pain points of nail technicians and the pressing challenges of small-sized products, this invention breaks through the limitations of existing products on user groups (such as beauty-conscious women) and product specifications (such as mini portable models), making it applicable to a wider range of scenarios and users. At the same time, the stable dry and wet separation effect also improves the product's adaptability to different storage environments (such as humid environments) and transportation conditions, further enhancing the product's market competitiveness.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0035] Example 1:

[0036] like Figure 1 , 2 As shown, a compressed towel liquid filling packaging box includes:

[0037] The box body has a mutually isolated compressed towel receiving chamber and a liquid receiving chamber to achieve dry and wet separation of the compressed towel and the liquid;

[0038] Compressed towels are sealed in a compressed towel receiving cavity through a packaging film.

[0039] The prepared solution is stored in the solution preparation container.

[0040] The pressing part is designed on the edge area of ​​the box and corresponds to the liquid receiving cavity; the pressing notch is opened on the box and is adapted to the outer edge of the pressing part, allowing the finger to apply force outward;

[0041] The conductive structure is designed between the compressed towel receiving cavity and the liquid receiving cavity, and is linked with the pressing part. When force is applied to the pressing part to make it flat, the conductive structure opens, and the liquid in the liquid receiving cavity flows into the compressed towel receiving cavity through the conductive structure, thereby adding liquid and wetting the compressed towel.

[0042] As a preferred embodiment, the pressing part is a deformable base structure. The initial state of the base structure is convex, and it becomes flat after being pressed. The deformation process of the base structure drives the conduction structure to open.

[0043] As a preferred embodiment, the isolation method between the compressed towel receiving chamber and the liquid receiving chamber is as follows: a sealing partition is designed inside the box, the sealing partition forms the isolation boundary between the two chambers, and the conductive structure is designed on the sealing partition.

[0044] As a preferred embodiment, the conduction structure is a preset break line or a one-way valve; when the pressing part is pressed flat, the preset break line breaks or the one-way valve opens, allowing the liquid to flow into the compressed towel receiving cavity in one direction.

[0045] As a preferred embodiment, the pressing notch 6 is arc-shaped or rectangular, and the depth of the pressing notch is not less than 1 / 2 of the thickness of the box wall, so as to accommodate the angle of finger application.

[0046] As a preferred embodiment, the packaging film is a food-grade PE film or PET film, and the film is sealed and adhered to the edge of the cavity of the compressed towel receiving cavity to prevent the compressed towel from getting damp before use.

[0047] The following are application examples based on the above technical solution:

[0048] Example 1 (Standard Size Single-Piece Product)

[0049] 1.1 Component Composition and Parameters

[0050] The compressed towel liquid filling packaging box of this embodiment is suitable for single compressed towels of standard size (e.g., 50mm in diameter and 15mm in overall height). The specific design of each component is as follows:

[0051] Box 1: Made of food-grade PP (polypropylene) material, injection molded into a circular, thin-shell structure with uniform wall thickness of 1.2mm, possessing a certain degree of deformation toughness (it can return to its flat state after being pressed, with no risk of breakage). The interior of the box is divided into two independent chambers by an integrally molded annular sealing partition—the inner compressed towel receiving chamber 5 (35mm in diameter, 8mm deep) and the outer liquid receiving chamber 4 (8mm in annular width, 8mm in depth). The height of the sealing partition is the same as the height of the box (15mm), ensuring complete isolation between the two chambers and achieving dry and wet separation. Simultaneously, a pressing notch is provided on the edge of the box (corresponding to the outer wall of the liquid receiving chamber). This notch is arc-shaped, with an arc length of 20mm and a depth of 1.0mm (greater than half the thickness of the box wall, providing sufficient space for finger pressure). The edges of the notch are rounded (0.5mm radius) to prevent scratching fingers or nails.

[0052] Compressed Towel 2: The compressed towel is made of soft cotton material with a weight of 30g. After compression, it forms a cylindrical block structure with a diameter of 32mm and a thickness of 5mm. It is individually sealed and packaged with food-grade PE (polyethylene) film. The film and the edge of the cavity containing the compressed towel are sealed by heat pressing (2mm sealing width) to ensure that the compressed towel is dry before use. The tensile strength of the film is ≥15MPa to avoid damage during transportation.

[0053] Solution 3: Sterilized purified water (meeting the requirements of GB19298-2014 "National Food Safety Standard for Packaged Drinking Water"), with a solution volume of 5mL. After being directly injected into the solution container, it is sealed through the aluminum foil sealing film (0.08mm thick) on the top of the box. The aluminum foil film is bonded to the edge of the solution container opening with hot melt adhesive, with a sealing strength ≥5N / 15mm, to prevent solution leakage.

[0054] Pressing part: Located on the outer bottom of the liquid-containing cavity at the edge of the box, it is a raised base structure integrally formed by the box body. In the initial state, the raised height is 3mm (in a hemispherical shape). The diameter of the raised area matches the arc length of the pressing notch (20mm). The wall thickness of the pressing part is consistent with that of the box body (1.2mm), ensuring that it can be uniformly deformed to a flat state when pressed (the raised height is 0mm after deformation).

[0055] Conductive structure: Located at the bottom of the sealing partition (directly above the pressing part), it is a pre-set fracture line structure—the fracture line is an annular micro-slit (0.8mm deep, 0.1mm wide) opened on the sealing partition. The inside of the micro-slit is covered with a thin PE film (0.05mm thick). In the initial state, the PE film remains intact, isolating the liquid from the compressed towel; when the pressing part is pressed and deformed, the internal pressure of the liquid receiving cavity increases, pushing the PE film to rupture and breaking the pre-set fracture line, forming a 5mm diameter through hole, allowing the liquid to flow into the compressed towel receiving cavity.

[0056] 1.2 Component Assembly Process

[0057] First, place the PE-coated packaging of compressed towel 2 into the compressed towel receiving cavity of box 1, ensuring that the film is aligned with the edge of the cavity opening. Then, use a hot-pressing device to heat-seal the film and the cavity opening (temperature 120℃, pressure 0.3MPa, time 3s). Inject 5mL of sterile purified water (solution 3) into the solution receiving cavity, ensuring that there are no air bubbles. Then, cover the cavity opening of the solution receiving cavity with aluminum foil sealing film and use a hot melt adhesive device to bond and seal it (temperature 80℃, pressure 0.2MPa, time 2s). Check the sealing performance of the box: immerse the assembled packaging box in room temperature clean water (depth 100mm) for 5 minutes and observe whether there is any water leakage in the two chambers. Once it is confirmed that there is no leakage, it is a qualified product.

[0058] 1.3 Work Process and Results

[0059] When using the product, the user inserts their fingers (especially those with manicured nails) into the pressing notch on the edge of the box, with the fingertips pointing outwards and aligned with the pressing part (protruding base). Pressure is applied perpendicular to the bottom of the box to the pressing part (required pressure ≤ 10N, no excessive force required). The pressing part gradually deforms from a protruding state to a flat state. During this process, the internal space of the liquid preparation chamber shrinks and the pressure increases. The pressure pushes the liquid preparation 3 within the liquid preparation chamber to compress the PE film on the sealing partition, causing the PE film to rupture and triggering the preset break line to disconnect, opening the guide hole. The liquid preparation 3 flows uniformly into the compressed towel preparation chamber through the guide hole, contacting the compressed towel 2. After the liquid preparation has completely flowed in (approximately 10 seconds), the compressed towel begins to absorb water and expand. The user then tears off the PE film covering the compressed towel and removes the expanded towel for use. The effects of this embodiment: When users wearing long nail polish (15mm in length) press, the outward application of force by the fingertips avoids interference between the nail polish and the middle of the box, eliminating the risk of nail polish breakage; the pressing force required is small, making it easy for even female users to operate; there is no leakage when dispensing liquid, and the water content is uniform after the compressed towel expands (water content ≥80%), meeting the needs of cleaning use.

[0060] II. Example 2 (Small-sized, thin product)

[0061] 2.1 Component Composition and Parameters

[0062] This embodiment is designed for small, thin products (e.g., 35mm in diameter and 8mm in overall height), suitable for mini-portable scenarios. The components are adjusted based on Embodiment 1 as follows: Box 1: still made of food-grade PP material, wall thickness reduced to 1.0mm, overall height 8mm; compressed towel receiving cavity (25mm in diameter, 5mm in depth), liquid receiving cavity (5mm in annular width, 5mm in depth); pressing notch is rectangular (15mm in length, 5mm in width, 0.8mm in depth), suitable for fingertip pressure;

[0063] Compressed Towel 2: Select a thin, soft cotton towel weighing 20g. After compression, the size is 22mm in diameter and 3mm in thickness, with the PE film thickness reduced to 0.03mm (to ensure portability).

[0064] Solution 3: The volume is reduced to 3mL, and the aluminum foil sealing film thickness is 0.06mm; Press part: The protrusion height is reduced to 2mm (thin design to match the overall height of the product), and the conduction structure is changed to a one-way valve (made of silicone, 3mm in diameter). There is no need to preset the break line - when pressing, the solution pressure pushes the valve core of the one-way valve to open, and the valve core automatically closes after the solution flows in (to prevent backflow).

[0065] 2.2 Work Process and Results

[0066] The user inserts their finger into the rectangular pressing notch, applies pressure (≤8N) to the thin pressing part, and the pressing part deforms until it flattens, increasing the pressure in the liquid receiving chamber. The liquid pushes the one-way valve core to open, and liquid 3 quickly flows into the compressed towel receiving chamber (takes approximately 8 seconds). After the liquid flows in, the one-way valve automatically closes to prevent backflow of water from the compressed towel. The compressed towel is then expanded and can be removed for use. The advantages of this embodiment are: a small, thin product (8mm thick) still ensures effective pressing space, eliminating the problem of "insufficient pressing"; the one-way valve design simplifies the manufacturing process and reduces costs; it is suitable for mini storage scenarios such as pockets and cosmetic bags, significantly improving portability.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
