Description

1. Title of the invention

[0001] Flushable, sectionally resting on the inner toilet ceramic, floating sanitary hygiene insert to prevent splashing, contamination and aerosol reduction through optimized ventilation geometry and the formation of a slippery separating layer to reduce adhesion to the toilet ceramic. 2. Technical field

[0002] The invention relates to a disposable hygiene product for the sanitary sector, in particular a flushable insert for use in water-filled toilet bowls.

[0003] The invention is suitable for flat flush toilets, deep flush toilets and other toilet designs in the private, public, medical and care sectors. 3. State of the art / Background of the invention

[0004] When using toilets, the impact of excrement on the water's surface often causes splashing. This is not only unhygienic, but also leads to contamination of the toilet bowl and the formation of aerosols that can spread germs into the surrounding air.

[0005] Known solutions for reducing backsplash include: * loosely inserted toilet paper * simple, mostly circular or rectangular paper inserts made of cellulose.

[0006] However, these well-known solutions have disadvantages. In particular, flat, closed pads tend to trap air underneath them when placed on the water's surface. This creates buoyancy, causing the pad to bulge or float uncontrollably (the so-called "trampoline effect"). As a result, the pad does not reliably fulfill its protective function. Furthermore, with these well-known solutions, there is often direct contact between the excrement and the ceramic surface of the toilet bowl, leading to adhesion, soiling, and increased cleaning effort. Object of the invention

[0007] The object of the invention is to provide a flushable sanitary hygiene insert that: * controlled venting when placed on the water surface, * a flat, stable contact with the water surface and, in sections, with the inner toilet ceramic allows, * Reliably reduces backsplash water * easy to manufacture and dispose of, * can be used without affecting the wastewater infrastructure. 5. Solution of the invention

[0008] The task is solved by a floating, flushable sanitary hygiene insert that rests in sections on the toilet ceramic and has a multi-lobed basic structure with radial incisions.

[0009] The multi-lobed design of the toilet seat liner allows trapped air to escape when placed on the water's surface. This reduces buoyancy and ensures the liner lies flat and flat against the water's surface, effectively suppressing splashing and aerosol formation. Furthermore, the liner is designed so that its central area rests on the water's surface, while the outer edges are at least partially supported by the inner ceramic surface of the toilet bowl. This further stabilizes the liner and reduces slippage or floating. Simultaneously, the flat liner creates a smooth, lubricating layer between waste and the toilet bowl, minimizing adhesion and soiling to the bowl walls and facilitating flushing.

[0010] In a preferred embodiment, the insert has a cloverleaf-like multi-leaf structure. 6. Detailed description of preferred embodiments

[0011] The insert consists of a water-soluble, biodegradable fibrous material, in particular cellulose, recycled paper, airlaid material or a combination of these materials.

[0012] In a preferred embodiment, the insert is composed of multiple layers, wherein: * two outer layers made of tear-resistant, washable paper, * an inner layer of softer cellulose or toilet paper is provided for stabilization. * The choice of material and surface finish creates a slippery surface when wet, reducing contact between excrement and toilet ceramics and preventing adhesion. * In the position of use, the insert rests with its central area on the water surface, while the outer edges of the sheet rest at least partially on the toilet ceramic and support the insert laterally.

[0013] The individual layers are connected to each other by: * mechanical embossing or pressing, * Spot bonding with water-soluble adhesive, * or other water-soluble and environmentally friendly binding techniques.

[0014] The insert is designed so that upon contact with water, its structural strength is gradually lost and completely removed during the rinsing process.

[0015] The dimensions of the insert are chosen so that the water surface of standard toilet bowls is largely covered, with typical diameters ranging from about 20-24cm.

[0016] Optionally, the insert can have a handle tab or an extended flap area, enabling hygienic, low-touch placement. 7. Commercial Applicability

[0017] The invention is industrially producible and commercially applicable. It is particularly suitable for use in: * Private households, * public toilet facilities, * Nursing homes and hospitals, * Hotels, restaurants and transport, * Mobile sanitary systems and camping toilets.
