Description
DISPOSABLE TOILET-SEAT COVER AND METHOD OF USING SAME
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of US Provisional Patent Application Serial No. 62/844,414, filed May 07, 2019.
FIELD OF THE DISCLOSURE
The present disclosure relates generally to a sanitary apparatus, and in particular to a disposable toilet seat and a disposable toilet-seat cover.
BACKGROUND
Toilets and in particular public toilets face various sanitary issues.
Generally, a sitting toilet comprises a toilet seat for a user to sit thereon. While the toilet seat may be periodically sanitized, sanitizing toilet seats may only be practically applicable for private toilets such as home-use toilets or toilets in hotel guest-rooms. Public toilets such as those in public areas (e.g., coffee shops, stores, malls, public areas of hotels, and the like) are generally used in high frequencies and it is usually difficult or even impossible to sanitize toilet seats of public toilets before every use.
Date Recue/Date Received 2020-05-07 Sanitarily protective toilet-seat covers are known. For example, US Patent No. 4,979,237 teaches a disposable protector for toilet seats having a cover of paper or similar material with a center cut-out generally conforming to the opening in the seat. The cover has a retainer member which may be in the form of a flange or tab which engage the inner edge of the seat to temporarily secure the protector in place during use. The underside of the cover may also have a frictional material such as latex or a low-tack adhesive. The cover may be treated with a suitable anti-bacterial agent and may be provided to the consumer in a dispenser or in individualized packages that may be conveniently carried by the user.
However, such a cover has issues such as the burden to the user to manually put the cover onto the toilet seat before each use, and the need of sufficient alignment between the cover and the toilet seat. Any misalignment between the cover and the toilet seat may lead to direct contact between the user's skin and the toilet seat thereby causing health risks to the user.
US Patent Publication No. 2005/0144710 teaches a toilet-seat cover device for automatically laying toilet-seat cover. In particular, US 2005/0144710 teaches a clean toilet seat capable of covering the toilet seat with a toilet-seat cover sheet automatically, securely and quickly, with such a cover sheet being replaced at each time of use so that people can always avoid contact with skin of others. In a thing having a toilet seat body placed on a surface of a toilet stool body, and an opening and closing lid pivotally mounted to the toilet seat body and covering a surface of the toilet seat, a plurality of cover sheets are housed in the above-described opening and closing lid, and on an occasion of movement to close the opening and closing lid, the cover sheet covers the surface of the toilet seat body.

2 Date Recue/Date Received 2020-05-07 However, such a toilet-seat cover device has issues such as the burden to the user to manually put down the toilet lid and press it against the toilet seat to stick a toilet-seat cover sheet onto the toilet seat. As the unused toilet-seat cover sheets are stored in the toilet lid and the sticky surface of the front-most sheet is exposed to the air, any contamination of the sticky surface of the front-most sheet may cause the front-most sheet unable to stick to the toilet seat.
Moreover, such a toilet-seat cover device may not allow the toilet-seat cover sheet to sufficiently align with the toilet seat if the toilet lid is loose. Any misalignment between the cover and the toilet seat may lead to direct contact between the user's skin and the toilet seat thereby causing health risks to the user.

As shown in FIG. 3, the shape of the substrate 104 is similar to that of the seat-cover sheet 102 except that the substrate 104 may not comprise a tab 110 extending rearwardly from the rear portion 108 thereof.
FIGs. 4A to 4C are cross-sectional views of the disposable toilet-seat cover 100 along cross-sectional lines A-A, B-B, and C-C, respectively. As can be seen, each of the seat-cover sheets 102 and the substrate 104 has a slightly curved cross-section such that the seat-cover stack formed by the seat-cover sheets 102 has a cross-section with slightly curved upper and lower sides for adapting to the profile of the top surface of the toilet seat.
In these embodiments, the substrate 104 is made of a material with a sufficient strength for maintaining the shape thereof during handling and for supporting the seat-cover sheets 102 stacked thereabove under pressure when use. For example, the substrate 104 may be made of a paperboard, a plastic board, a metal board, and/or the like. The bottom surface of the substrate 104 is coated with a layer of a first adhesive such as a pressure-sensitive adhesive, a low-tack adhesive, and/or the like, for separably or demountably attaching to a toilet seat.
Each seat-cover sheet 102 is a thin layer of a disposable material such as paper. The bottom surface of each seat-cover sheet 102 (except the tab 110 thereof) is coated with a layer of a second adhesive such as a pressure-sensitive adhesive, a low-tack adhesive, and/or the like, for separably or demountably attaching to the seat-cover sheet 102 thereunder or to the substrate 104. In various embodiments, the first and second adhesives may be different
As shown in FIG. 3, the shape of the substrate 104 is similar to that of the seat-cover sheet 102 except that the substrate 104 may not comprise a tab 110 extending rearwardly from the rear portion 108 thereof.
FIGs. 4A to 4C are cross-sectional views of the disposable toilet-seat cover 100 along cross-sectional lines A-A, B-B, and C-C, respectively. As can be seen, each of the seat-cover sheets 102 and the substrate 104 has a slightly curved cross-section such that the seat-cover stack formed by the seat-cover sheets 102 has a cross-section with slightly curved upper and lower sides for adapting to the profile of the top surface of the toilet seat.

In these embodiments, the tab 110 of each seat-cover sheet 102 is not coated with any adhesive to allow a user to hold and peel the seat-cover sheet 102 off from the stack.
In some embodiments, the top surface of each seat-cover sheet 102 is coated with a suitable waterproof, water-repellent, impermeable, and/or water-resistant material for preventing water-based liquid (such as urine) from seeping or penetrating through the topmost seat-cover sheet 102 to the seat-cover sheet 102 thereunder when the water-based liquid is spilled onto the disposable toilet-seat cover 100.
FIGs. 5A and 5B illustrate a process of installing the disposable toilet-seat cover 100 onto a toilet seat 202.
As shown in FIG. 5A, to install the disposable toilet-seat cover 100, the toilet seat 206 of the toilet 202 is first lowered onto the toilet bowl 204. Then, the disposable toilet-seat cover 100 is put onto the toilet seat 206 as indicated by the arrow 208 with the substrate 104 facing the top surface of the toilet seat 206.
As shown in FIG. 5B, a downward pressure 210 is applied to the disposable toilet-seat cover 100 at multiple positions thereof against the toilet seat 206 to demountably attach the disposable toilet-seat cover 100 to the toilet seat 206. The disposable toilet-seat cover 100 is then installed onto the toilet seat 206. After installation, the toilet seat 206 and the disposable toilet-seat cover 100 attached thereto may be turned to an upright position or may be lowered onto the toilet bowl 204 as needed.
Date Recue/Date Received 2020-05-07 FIGs. 6A and 6B illustrate a process of preparing the disposable toilet-seat cover 100 before a use of the toilet 202.
As shown in FIG. 6A, a user (not shown) may grab the tab 110 of the topmost seat-cover sheet 102-1 and pull it upward as indicated by the arrow 242 to overcome the adhesion of the adhesive between the topmost seat-cover sheet 102-1 and the seat-cover sheet 102 thereunder.
As shown in FIG. 6B, the topmost seat-cover sheet 102 is then peeled off from the disposable toilet-seat cover 100 and may be disposed.
As shown in FIG. 6C, the next seat-cover sheet 102-2 is then at the topmost and the toilet 202 is ready for use.
As the top surface of each seat-cover sheet 102 is coated with a suitable waterproof, water-repellent, impermeable, and/or water-resistant material, contamination to the topmost seat-cover sheet 102 would not seep or penetrate therethrough to the seat-cover sheet 102 thereunder. Therefore, if the topmost seat-cover sheet 102 is contaminated, the user may simply peel off the contaminated seat-cover sheet 102 and use the uncontaminated one thereunder.
