It will be further understood that the terms “comprises”, “comprising,”, “includes” and/or “including”, when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
- The following detailed description includes the best currently contemplated mode or modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention will be best defined by the allowed claims of any resulting patent.
- Referring to the drawing depicted is a perspective view of the disclosed bathtub liner shown in a flat profile. The
bathtub liner 100 includes acushioning layer 110 that may be sufficiently thick to provide comfort to the user sitting or lying over the disclosed bathtub liner. For example, the cushioning layer can be made from suitable foam, such as latex foam, polyurethane layer, and the like foams known to a skilled person. The bathtub liner can be rectangular in shape having an elongated profile and the size of the bathtub liner may be proportional to the size of the bathtub for which the bathtub liner has to be used. The corners of the bathtub liner can be rounded and such modifications in shape and size are within the scope of the present invention. For bathtubs of round and square shapes, bathtub liners of similar shapes i.e., round and square can be designed. - The cushioning layer can be sandwiched between a
bottom layer 120 and anupper layer 130. The bottom layer can be thick, cut-resistant, and impermeable to water. The thick bottom layer may be resistant to damage such as cutting and chipping from the damaged inner surface of the bathtub. For example, the bottom protective layer can be made from thick plastic that may be flexible and waterproof. - The upper layer can be thinner than the bottom layer and must be impermeable to water. Both the bottom layer and the upper layer are of a size larger than the cushioning layer, such that the edge portions of both layers can be bonded together. For example, the upper layer and the bottom layer sandwiching the cushioning layer can be bonded together along the edges thereof to sealably encase the cushioning layer. The edge portions of the bottom layer and the upper layer can be bonded in a variety of ways, such as using adhesive or heat bonding the two layers together. The binding must provide a seal against water to prevent the ingress of water that may wet the cushioning layer.
- The cushioning layer can optionally be covered by an opaque layer on the top side or maybe both sides of the cushioning layer. This opaque layer may hide the cushion structure providing an aesthetic appearance to the bathtub liner. In such a case, the upper layer may be made transparent so that the opaque layer is visible from the outside. Preferably, suitable designs can be disposed on the opaque layer to further add aesthetic appeal to the bathtub liner. For example, the foam layer can be covered in a fabric having a design on at least its upper surface i.e., the surface adjacent to the upper layer of the bathtub liner.
- A drainage hole can also be provided in the bathtub liner through which water in the bathtub lined with the disclosed bathtub liner can be drained. The position of the drain hole in the bathtub liner can correspond to the position of the drain hole in the bathtub.
Bracket 140 can be used to seal the drain hole preventing the ingress of water between the upper layer and the bottom layer. The bracket can be hollow and cylindrical in shape with a top member and a bottom member. The edge portion of the upper layer and the bottom layer along the drain hole can be sealably sandwiched between the top member and the bottom member of the bracket. The bracket also provided rigidity for the water to easily pass through. The bottom member of the bracket can fit into the drain hole of the bathtub so that water can directly flow into the drain and the bathtub may remain dry. The top and bottom members of the bracket can be coupled using a variety of ways such as using an adhesive, heat bonded, or fastening along threads provided in both the top member and bottom member of the bracket. The bracket can be made from rigid and durable plastic or metal. - While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
