CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 739,495, filed Dec. 28, 2024, and is incorporated by reference in its entirety herein for all purposes.FIELD OF INVENTION
[0002] The present invention relates generally to child toileting aids, and more particularly to disposable devices for reducing the toilet seat opening size of a toilet seat to accommodate toddlers and young children. The present invention is directed to sanitary, single-use toilet seat adapters that adhere to the seat surface, thereby providing a smaller opening suitable for toddlers or young children, during toilet use including, routine use, potty training or use in public restrooms.BACKGROUND OF THE INVENTION
[0003] Adult toilet seats are designed with openings sized for full-grown users, which presents difficulties for toddlers or young children who are learning to use the toilet due to the physical size differences between an adult's body and a toddler's or child's body. Conventional solutions include reusable toilet seat reducers, portable potty seats, and disposable covers. While these devices address certain aspects of hygiene or aperture reduction, they suffer from limitations in convenience, portability, sanitation, and compatibility with public toilets. Additionally, many prior art devices are mechanically complex presenting challenges in manufacturing with attendant higher production expense.
[0004] One of the earliest attempts to address this problem is U.S. Pat. No. 3,316,560 A (“Disposable Toilet Seat Cover”), which discloses a compact, foldable cover that installs over a toilet seat to make the seat smaller and more comfortable for children. This design lacks adhesive bonding, does not include a hygienic pull tab for removal, and does not ensure secure placement when a child moves or wiggles. In addition, the dual sheet design will allow bodily fluids to collect between the layers. And, as depicted, the 560 device is mechanically complex having many components requiring expensive complex manufacturing processes.
[0005] Another approach is U.S. Patent Application Publication No. 2009 / 0070921 A1 (“Disposable Toilet Seat Cover for Use in Potty Training”), which describes a collapsible, portable disposable potty-training device designed to fit on a conventional toilet seat. While single-use and child-sized, it relies on a mechanical fit rather than adhesive bonding, is structurally complex, and does not provide compact portability or hygienic removal. And, as previously noted, the 921 device is mechanically complex having many components requiring expensive complex manufacturing processes.
[0006] Commercial products marketed as disposable toilet seat covers, sold on Amazon and in many retail outlets, are marketed for toddlers and young children and employ adhesives to attach material to the toilet seat while reducing the aperture size. However, such products present several limitations. The adhesive on such products must be picked off the toilet seat after use, which is inconvenient and requires users to touch the toilet surface, which after all effectively negates the use of the toilet seat cover. The covers do not hold securely when a child wiggles, leading to instability during use. They are incompatible with non-standard toilet surfaces such as portable toilets (Porta Potties), and their bulk prevents easy storage in a small purse.
[0007] Accordingly, there remains a need for a mechanically simple, disposable, hygienic, compact, and portable toilet seat reducer that can be applied quickly, securely, and removed without direct contact with the toilet seat surface. The present invention addresses these deficiencies by providing a disposable adhesive equipped toilet seat adapter sheet with a hygienic pull tab and optional integrated handles formed from the adapter sheet material itself. The adhesive equipped toilet seat adapter sheet ensures secure placement, easy removal, and compatibility across a wide range of toilet types, including public and portable toilets, while maintaining a compact form suitable for on-the-go use.SUMMARY OF THE INVENTION
[0008] The present invention provides a disposable waterproof toilet seat adapter with adhesive on one side, configured to removably adhere to the upper surface of a toilet seat. The toilet seat adapter reduces the effective opening size of the seat, enabling toddlers or young children to sit securely. The toilet seat adapter may be formed as a full-cover annular overlay or as a transverse strip spanning the seat opening. A sanitary pull tab is integrated to allow removal without direct contact with toilet seat surfaces. Optional gripping handles may be incorporated into the toilet seat adapter to provide stability for the child. Additionally, the toilet seat adapter may be manufactured from a hypoallergenic material and may further possess antimicrobial properties. The present invention offers a disposable, sanitary, portable, and cost-effective solution for toddlers or young children toileting in both home and public environments, while overcoming the adhesive residue, instability, and limited compatibility issues found in existing disposable covers.BRIEF DESCRIPTION OF FIGURES
