Description

Technical Field

[0001] This application relates to the technical field of sanitary products, and particularly to a sticking type toilet isolation pants that can adhere to the human skin when using a public or household sitting toilet.

Background Art

[0002] With the improvement of the public's health awareness, the number of users who are concerned about contamination by contact when using the sitting toilet in public toilets is increasing. Conventional disposable toilet seat cushions generally adopt paper or non-woven fabric materials, which are directly laid on the surface of the toilet seat and can only cover the upper area of the toilet seat, and cannot completely block the direct contact between the human skin (especially the inner thighs, perineum and buttocks) and the toilet seat. In addition, such cushions are prone to displacement, warping and falling off due to changes in the sitting posture during use, and the protection effect is significantly reduced.

[0003] Furthermore, most of the conventional toilet seat cushions have a passive covering structure and do not have the function of adhering to the human body, and cannot cope with the differences in the physiological structures of users of different genders. For example, when a woman urinates, when using a normal toilet seat cushion, if the cushion is displaced, it will contact the contaminated toilet seat and is prone to infection by bacteria, and there is a health risk. Currently, there is no solution in the market that can reliably adhere to the human body while appropriately avoiding the excretion area and can be discarded or flushed into the sewer.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, it is necessary to provide a new type of sticking type toilet isolation pants that can directly and stably adhere to the skin areas such as the roots of the user's thighs and the waist and hips through a peelable adhesive layer, ensure a constant isolation state by following the movement of the human body during toilet use, and at the same time, provide reasonable excretion ports and auxiliary openings suitable for the physiological structures of men and women respectively, and adopt water-soluble and water-disintegrable materials to simplify the post-use treatment and achieve both hygiene, comfort and environmental friendliness. [Means for solving the problem]

[0005] The present invention aims to provide adhesive toilet isolation pants that, by providing a fixing part with an adhesive layer on the isolation cushion body and configuring the fixing part to be removably adhered to the skin of the human body, allow the isolation cushion to displace in accordance with the movement of the human body, effectively cover the contact area between the human body and the toilet seat, prevent the user's skin from directly contacting the surface of the toilet bowl, significantly improve hygiene and safety when using the toilet, and prevent loss of protective function due to shifting or displacement of the cushion.

[0006] To achieve the above objective, the present invention provides the following technical solution: Adhesive toilet isolation pants, comprising an isolation cushion body, the isolation cushion body having a contour shape in an unfolded state that conforms to the area of ​​the buttocks and thighs that come into contact with the toilet seat when a person is seated, used to cover the area of ​​the person's body that comes into contact with the toilet, and having an excretory opening at a position corresponding to the excretory area of ​​the person's body, the isolation cushion body having a first surface facing the person's body and a second surface facing the toilet seat, and at least two fixing parts, each provided on the first surface of the isolation cushion body, and each fixing part having an adhesive layer on its surface for removably adhering the isolation cushion body to the skin of the person's body.

[0007] In some embodiments, a removable release paper is covered on the outside of the adhesive layer.

[0008] In some embodiments, an auxiliary opening is further provided in the region of the isolation cushion body corresponding to the perineum of the human body, the excretory opening is connected to the auxiliary opening, and the auxiliary opening is used to accommodate the urination needs of female users.

[0009] In some embodiments, the at least two fixing parts include two first fixing parts, the two first fixing parts corresponding to areas of skin on the left and right posterior thighs of the human body.

[0010] In some embodiments, the at least two fixing parts include two second fixing parts, which, when in use, correspond to areas of skin on the outer left and right thighs of the human body.

[0011] In some embodiments, the at least two fixing parts include two third fixing parts, and when in use, the two third fixing parts correspond to areas of skin on the left and right hips of the human body.

[0012] In some embodiments, several tear-resistant structures are provided on the edge of the isolation cushion body, and some of these tear-resistant structures are one or a combination of perforated holes, laser-cut micro-cuts, or pre-weakened tear lines.

[0013] In some embodiments, the adhesive layer is a medical-grade pressure-sensitive adhesive layer.

[0014] In some embodiments, the material of the isolation cushion body is a water-soluble material.

[0015] In some embodiments, the isolation cushion body has a U-shaped, Ω-shaped, or saddle-shaped contour when unfolded, so as to fit the area of ​​the front of the toilet seat and the base of the thighs on both sides. [Effects of the Invention]

[0016] As can be seen from the analysis, the adhesive toilet isolation pants according to this invention are designed with an isolation cushion body that conforms to the area where the base of the thighs make contact when the person is seated, and have multiple fixing parts (including the back of the thighs, the outside, and the waist and buttocks) equipped with a medical-grade pressure-sensitive adhesive layer on the first surface, thereby enabling the isolation cushion to be removably and stably adhered to the skin of the human body. When in use, the isolation cushion displaces in accordance with the movement of the human body, effectively covering the important contact area between the human body and the toilet seat, fundamentally preventing the skin from directly contacting the surface of public or private toilets, greatly improving hygiene and safety when using the toilet, and effectively reducing the risk of cross-infection.

[0017] At the same time, the isolation cushion itself is equipped with an excretory opening and an auxiliary opening specifically designed for female users. The connection between the two creates an open structure that accommodates the needs of female urination, ensuring privacy and functionality while accommodating the physiological characteristics of both men and women and enhancing comfort and convenience of use.

[0018] Furthermore, the isolation cushion is made of water-soluble material and can be flushed down the toilet after use. It dissolves quickly in water, preventing pipe blockages and achieving both environmental friendliness and ease of disposal. The easily tearable structure at the edges allows users to easily cut and adjust parts of the cushion to suit their body shape and usage habits, improving the product's versatility. The adhesive layer is covered with release paper to prevent contamination before use, and the medical-grade pressure-sensitive adhesive is gentle on the skin and has appropriate adhesive strength, ensuring reliable fixation while avoiding skin discomfort when removed.

[0019] In summary, this invention offers multiple advantages, including dynamic adhesion, precise protection, gender-specific specifications, environmental friendliness, water solubility, and ease of use. It overcomes the technical shortcomings of conventional toilet seat cushions, such as their tendency to shift, insufficient coverage, inability to adhere closely to the body, and inconvenient disposal. This provides a highly safe, hygienic, considerate, and environmentally friendly disposable toilet seat isolation solution. [Brief explanation of the drawing]

[0024] As shown in Figures 1 to 7, the present invention provides adhesive toilet isolation pants according to its embodiments. The overall structure is designed to improve hygiene, safety, comfort, environmental friendliness, and convenience when using the toilet. The isolation cushion for the toilet seat includes an isolation cushion body 1, which, when unfolded, has a contour shape that conforms to the area of ​​the buttocks and thighs that come into contact with the toilet seat when a person is seated. This contour is not a simple flat sheet-like structure, but a three-dimensional, close-fitting form formed with ergonomics in mind. Specifically, one of a U-shape, Ω-shape (omega-shape), or saddle shape can be adopted. In the case of a U-shaped structure, the opening at the front edge is relatively large, and the wings on both sides extend backward, making it compatible with most general-purpose standard toilet seats, and is particularly convenient for women to urinate forward. In the case of an omega-shaped structure, the entire structure forms a closed ring shape, but the front has a relatively large opening and the rear is formed to be slightly wider, allowing it to wrap around both sides of the buttocks well and improve stability. In the case of a saddle-shaped structure, the central part is concave and the sides are raised, and the design follows the distribution of the ischial tuberosities of the human body, so that the cushion can maintain its structural integrity even when a load is applied and prevent the accumulation of wrinkles. In either of the above structures, it is possible to accurately cover important areas that come into direct contact with the toilet seat when the user is seated (front of the back of the thighs, around the perineum, and the front edge of the buttocks) while avoiding the excretory route, thus achieving both functionality and protection.

[0025] In some embodiments, the material of the isolation cushion body 1 is a water-soluble or water-disintegrating material, and is generally a thin sheet with a basis weight (g) of 15 g / m² in a dry state. 2 ~80g / m 2The sheet has a thickness of 15-80 gsm and disintegrates, dissolves, or disperses within 15-600 seconds upon contact with room temperature water. The sheet may be selected from one of the following: wood pulp paper, polyvinyl alcohol (PVA) water-soluble nonwoven fabric or water-soluble film, carboxymethylcellulose (CMC), polyethylene glycol (PEG), modified starch-based materials, or a composite system of the above materials. Here, the composite system of the above materials includes, but is not limited to, a laminated structure of a multilayer water-soluble film and a composite material of wood pulp fibers and natural fibers. The natural fibers are selected from cotton fibers, hemp fibers, bamboo fibers, or mixtures thereof. The above material has sufficient mechanical strength and flexibility in a room temperature dry state and does not break even when subjected to the seating load of a human body. When in contact with water (especially toilet flushing water), it rapidly disintegrates and dissolves completely within 15 seconds to 5 minutes, and does not cause pipe blockage. The material itself is non-toxic and non-irritating and meets the national biocompatibility standards for disposable sanitary products.

[0026] To ensure that the excretory function is not obstructed, an excretory opening 10 is provided in the isolation cushion body 1 at a position corresponding to the anus of the human body. The excretory opening 10 is a through-hole that penetrates the isolation cushion body 1 in the thickness direction, and its shape may be circular, oval, or teardrop-shaped, and its dimensions are set based on average physiological data of adults (for example, a diameter of approximately 30-50 mm), so that excrement can be effectively circulated while avoiding discomfort during use due to sharp edges.

[0027] In particular, to accommodate the physiological characteristics and urination habits of female users, this invention adds an auxiliary opening 20 in front of the excretion opening 10 (i.e., closer to the front of the human body). The auxiliary opening 20 is located in the area directly below the perineum of the human body and communicates with the excretion opening 10 to form a composite opening structure. With this design, female users do not need to completely lift their bodies or change their sitting posture when urinating, and urine can be smoothly discharged from the front auxiliary opening 20 without adhering to the surface of the isolation cushion body 1. This effectively prevents urine backflow, residual odor, and discomfort during use due to local dampness.

[0028] In some embodiments, flexible flange structures may be further provided on the edges of the excretion opening 10 and the auxiliary opening 20, the flanges being formed by hot pressing or die cutting of the same material and slightly curled in the direction of the first surface 1a. These allow for close contact with the contour of the skin to reduce friction and guide the liquid to flow in a predetermined direction, preventing contamination of other areas of the isolation cushion due to leakage.

[0029] The isolation cushion body 1 has a clearly defined menu surface. The first surface 1a facing the human body is in direct contact with the skin. Preferably, the first surface 1a has excellent affinity to the skin, low sensitization properties, and is treated with a micro-breathability finish. Comfort during contact is improved by applying or compounding a single layer of ultrafine fiber nonwoven fabric. The second surface 1b facing the toilet seat functions as an isolation barrier layer. By applying a hydrophobic or anti-fouling coating to the second surface 1b, even if it comes into contact with moisture or dirt remaining in the toilet bowl, it will not penetrate to the first surface 1a. This achieves "one-way isolation".

[0030] To address the shortcomings of conventional toilet seat cushions, such as their tendency to shift, warp, and fall off, this invention provides multiple pairs of fixing parts on the first surface 1a, and a medical-grade pressure-sensitive adhesive layer 3 is placed on each pair of fixing parts. This layer is used to removably adhere the isolation cushion body 1 to the skin of the human body, achieving a protective effect that "adapts to movement while adhering closely to the human body."

[0031] Specifically, the fixing portion includes two first fixing portions 2a and 2b, each provided on the inner side of both front wings of the isolation cushion body 1, and precisely corresponds to the upper skin area on the back of the left and right thighs of the human body (i.e., approximately 2-5 cm below the groin). The skin in this area is relatively flat, has relatively few sweat glands, has high adhesive stability, and is an appropriate adhesion site.

[0032] In some embodiments, the fixing portion further includes two second fixing portions 2c, 2d, each located on the outer side of the front wings of the isolation cushion body 1 and corresponding to the mid-skin on the outer side of the thigh. When the user sits with their legs naturally spread, these portions can also provide auxiliary fixing force, preventing lateral movement of the cushion due to leg movements.

[0033] In some embodiments, the fixing portion further includes two third fixing portions 2e, 2f, located on both sides of the rear end of the isolation cushion body 1, corresponding to the skin areas of the left and right lumbar and gluteal regions of the human body (i.e., below the iliac crest and above the gluteus maximus). These regions have a small load applied when seated but offer excellent support stability, effectively suppressing rearward slippage and rotation of the cushion.

[0034] The adhesive layers 3 in the first fixing parts 2a, 2b, the second fixing parts 2c, 2d, and the third fixing parts 2e, 2f are configured to be used to fix and adhere the isolation pants to a part of the human body. The adhesive layer 3 employs a water-soluble pressure-sensitive adhesive as the adhesive material, and by having appropriate initial tackiness and sufficient sustained tackiness in a dry state, it is possible to ensure that the product adheres stably to the human body when used. On the other hand, when it comes into contact with toilet flushing water after use, it dissolves quickly in a few seconds to a few minutes, without leaving any adhesive residue or clogging pipes, thus achieving simple disposal and environmental consideration.

[0035] In some embodiments, the adhesive material may be selected from any one of the following: a water-soluble pressure-sensitive adhesive, a water-soluble pressure-sensitive adhesive, a hot-melt adhesive, or a biodegradable pressure-sensitive adhesive. However, it is preferable to use a water-soluble pressure-sensitive adhesive that dissolves completely in water and leaves no non-degradable residue. This ensures that the water-soluble and water-disintegrating properties of the isolation cushion body are matched, and that the entire product has good dispersibility and environmental compatibility.

[0036] In some embodiments, a peelable release paper 4 (shown in Figure 7) is applied to any of its outer surfaces to prevent contamination of the adhesive layer 3 during storage and transportation. The release paper 4 may be a single, integrated sheet or divided into individual sections, and is easy to handle as the adhesive surface can be exposed simply by peeling it along the edge when in use.

[0037] Considering individual differences in the user's physique (thigh circumference, ischial distance), this invention provides a tear-resistant structure 5 on at least one or more edge regions of the isolation cushion body 1. The tear-resistant structure 5 may typically be one or a combination of the following forms: a perforated hole line with a series of spaced-apart micro-holes that are easy to tear along a predetermined path; laser-cut micro-cracks on the material surface with controllable depth using a laser, achieving both aesthetic appeal and accurate tear-guiding functionality; or a pre-weakened tear line, where the strength of a portion of the material is reduced by mechanical indentation or chemical treatment to form a tear-resistant guide line. Users can personally design the size to suit their needs by cutting off excess wing portions or adjusting the opening width along the tear-resistant structure 5, thereby improving the fit and usability.

[0038] This invention ensures that the isolation cushion adheres firmly to the user's body by rationally arranging multiple fixing parts, and that it displaces in accordance with the body's movements. This eliminates the problem of conventional toilet seat cushions being prone to shifting. At the same time, the auxiliary opening 20, which is specifically designed for women, improves the convenience and comfort of use. By adopting a water-soluble material and a tear-resistant structure, the invention achieves easy disposal after use and flexibility to accommodate a variety of users.

[0039] As described above, the adhesive toilet isolation pants according to the embodiment of the present invention solve the shortcomings of conventional toilet seat cushions, such as their tendency to shift, insufficient coverage, lack of gender-specific features, and difficulty in disposal, through multiple technical means including an ergonomically designed contour, gender-specific openings, adhesive fixation to the skin in multiple locations, water-soluble and environmentally friendly materials, and an adjustable edge structure. It achieves high hygiene, strong stability, good comfort, and sustainable environmental friendliness, possessing remarkable inventiveness and broad market applicability.

[0040] As can be seen from the above description, the above embodiment of the present invention achieves the following technical effects.

[0041] Firstly, it dynamically adheres to the body, preventing slippage and providing excellent stability. Multiple pairs of fixing points (including the back and outside of the thighs and the lower back and buttocks) are provided on the first surface of the isolation cushion body, and the cushion is directly adhered to the skin of the human body with a medical-grade pressure-sensitive adhesive layer. As a result, the isolation cushion can displace in accordance with the user's sitting posture, fundamentally avoiding the problems of conventional toilet seat cushions such as slippage, bending, displacement, and detachment due to sitting pressure, posture adjustment, or standing up movements, and ensuring effective isolation during toilet use.

[0042] Secondly, it provides precise protection and covers critical contact areas. The isolation cushion itself adopts an ergonomically designed contour such as a U-shape, omega-shape, or saddle shape to cover areas with a high risk of contact with the toilet seat, such as the groin, perineum, and anterior edge of the buttocks when seated, while avoiding the excretory route. This achieves rational area-specific protection, "protecting necessary areas while leaving the excretory area open," and significantly reduces the risk of cross-infection.

[0043] Third, the gender-conscious design meets the needs of female urination. An auxiliary opening that communicates with the urinary opening is designed for female users, allowing for smooth urination without changing posture. This prevents urine from sticking to the cushion or backflow, improving hygiene and user comfort, and while it is intended for unisex use, it achieves optimization for female users.

[0044] Fourth, it offers excellent usability and operability. Each fixing part is covered with a removable release paper to prevent contamination before use, and the edges are provided with an easy-to-tear structure (e.g., perforated holes, laser-cut micro-slits, etc.), allowing users to flexibly adjust the dimensions to their own size, improving the versatility and individual suitability of the product.

[0045] Fifth, it is environmentally friendly, dissolves in water, and is easy to dispose of. The isolation cushion itself is made of water-soluble material (e.g., PVA, CMC, etc.) and can be flushed directly down the toilet after use. It dissolves quickly in the water flow, does not cause pipe blockages or generate dried waste, and is suitable for both the convenience and sustainability demanded by modern urban life.

[0046] Sixth, it is gentle on the skin, highly safe, and meets medical standards. The adhesive layer used is a medical-grade pressure-sensitive adhesive that has passed biocompatibility tests, ensuring reliable adhesion while minimizing skin irritation during removal, preventing skin damage, leaving no adhesive residue, and having low allergenicity. The first surface is treated with a skin-friendly finish to further enhance contact comfort, making it suitable for users with sensitive skin.

[0047] Seventh, the structure is simple, costs can be controlled, and it is easy to mass-produce. The entire structure is a single-layer or multi-layer composite integral molded structure, does not require complex assembly processes, and can be manufactured by common processes such as die cutting, drilling, and paste coating, making it suitable for large-scale mass production and giving it excellent industrialization prospects.

[0048] The foregoing describes only a few embodiments of the present application and does not limit it. Those skilled in the art may have various modifications and changes to the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be within the scope of protection. [Explanation of Symbols]
