This disclosure is generally directed to toilets and more particularly to a toilet lid and seat that are formed of a laminar composite material.
Toilet seats and lids have existed in various forms for many decades. A toilet seat; provides a surface for an occupant to comfortably sit and a toilet lid provides a protective cover for the toilet facility. Generally, toilet seats and lids are made of wood or plastic materials. These materials can degrade, discolor, and/or become damaged over time. Thus, many toilet seats and lids may become unattractive, structurally unsound, or both.
Additionally, most toilet seats and lids have plain, unadorned surfaces that do not include any type of decoration or permit any artistic expression. Some conventional toilet seats have surfaces that are adorned with silk-screen printing, hand painting, water-transfer printing, heat transfer printing, and the like. However, the surfaces of these seats, like plain toilet seats, can wear, chip off, degrade, or otherwise become damaged over time. There are also polyresin toilet seats that are made from resin compounds and are typically clear with optional decorative inserts. However, polyresin toilet seats are typically heavy and expensive to manufacture.
According to one embodiment of the present disclosure, a composite laminar material includes a core structural layer. The composite laminar material also includes a first decorative graphic layer disposed on a first surface of the core structural layer. The composite laminar material further includes a plurality of exterior layers disposed on exterior surfaces of the core structural layer and the first decorative graphic layer.
In another embodiment, a toilet lid includes a core structural layer having a shape and size associated with the toilet lid. The toilet lid also includes a first decorative graphic layer disposed on a first surface of the core structural layer. The toilet lid further includes a plurality of exterior layers disposed on exterior surfaces of the core structural layer and the first decorative graphic layer, the exterior layers configured to envelop the toilet lid.
In still another embodiment a method of manufacturing a toilet lid includes preparing a core structural layer of the toilet lid. The method also includes applying a first decorative graphic layer to a first surface of the core structural layer. The method further includes applying a plurality of exterior layers to exterior surfaces of the core structural layer and the first decorative graphic layer.
Other technical features may be readily apparent to one skilled in the art from the following figures, descriptions and claims.
For a more complete understanding of this disclosure and its features, reference is now made to the following description, taken in conjunction with the accompanying drawings, in which:
The present disclosure provides a laminar composite toilet lid and seat configured to include decorative or aesthetic elements. The composite toilet lid and seat according to this disclosure offers many advantages. The toilet lid and seat may be customized with one or more images to convey a message or impression that may be of interest to a user. In addition, the toilet lid and seat according to this disclosure is constructed to be more durable and retain its original appearance for a longer period than conventional toilet lids and seats.
The laminar composite toilet lid and seat according to embodiments of this disclosure is constructed with five (5) layers of material: a core structural layer, two decorative graphic layers disposed on top and bottom surfaces of the core structural layer, and two exterior finish layers disposed on outside surfaces of the core structural layer and decorative graphic layers. All of the layers are integrated together to form a durable, attractive product.

The toilet lid 202 comprises five layers 302-310. For clarity of illustration, the thickness of each layer 302-310 may not be drawn to scale. Layer 302 is an exterior finish or coating layer. Layer 304 is decorative graphic layer. Layer 306 is a core structural layer. Layer 308 is a second decorative layer. In certain embodiments, the layer 308 may be composed of the same material as the layer 304. In other embodiments, the layer 308 may be composed of a different material than layer 304. Layer 310 is a second exterior finish or coating layer.
In accordance with the present disclosure, the exterior finish layers 302, 310 may be formed of polymethyl-methacrylate (PMMA). PMMA is a transparent, thermoplastic material that is very durable and exhibits excellent optical properties. PMMA is also scratch resistant, can be CNC (computer numerical control) machined, and is more impact resistant than ordinary glass. PMMA is also known by its trade names Plexiglas™ and Lucite. The thickness of each finish layer 302, 310 may be selected according to the requirements of the application. In one embodiment, the thickness of each finish layer 302, 310 is approximately two millimeters (2 mm). While the exterior finish layers 302, 310 are described as PMMA, the layers 302, 310 may be formed of another special function glass or any other suitable material that exhibits the advantageous properties of PMMA.
In some embodiments, each exterior finish layer 302, 310 is clear and colorless. However, the exterior finish layers 302, 310 are not limited thereto. For example, either one or both of the exterior finish layers 302, 310 may be colored, tinted and/or mirrored. Either one or both of the exterior finish layers 302, 310 may be smooth or textured, and have a glossy or matte finish.
The core layer 306 may be formed of a medium density fiberboard (MDF). As is known in the art, MDF is formed of wood fibers that are held together with one or more waxes or resins such as epoxies, formaldehyde resins, or phenolic resins. The fiber content and thickness of the MDF core layer 306 may vary based on application requirements. The core layer 306 accounts for the majority of the thickness of the toilet lid 202 and provides most of the rigidity of the toilet lid 202. In one embodiment, the thickness of the core layer 306 is approximately nine millimeters (9 mm). In an embodiment, one or both sides of the core layer 306 are painted to hide or protect the finish of the MDF material.
Although the core layer 306 is described as being formed of MDF, other materials may be used. For example, the core layer 306 may be formed of another composite wood, such as hardwood plywood (HWPW), particleboard (PB), high density fiber board (HDF), molded wood, or any other suitable material. In an embodiment, the core layer 306 may be formed of two or more sub-layers, each sub-layer comprising one of the materials described above.
Each of the decorative graphic layers 304, 308 is formed of a paper or thin plastic material or film onto which an image has been printed, painted, or otherwise formed. Each decorative graphic layer 304, 308 may be sized to cover all, or only a portion, of a surface of the toilet lid 202. In an embodiment, each decorative graphic layer 304, 308 may be completely opaque, thus hiding the underlying surface of the toilet lid 202. In another embodiment, each decorative graphic layer 304, 308, or some portion thereof, may be partially or completely transparent, thus exposing at least part of the underlying surface of the toilet lid 202.
Although the decorative graphic layers 304, 308 have been described as including a particular image, the decorative graphic layers 304, 308 are not limited thereto. For example, in lieu of a displaying a decorative or graphic image, one or both layers 304, 308 may be a plain colored paper or film in any suitable color. Thus, a solid white paper could be used to make a white toilet seats. A solid blue paper could be used to make a blue toilet seat.
Although
First, a core structural layer (e.g., layer 306) is prepared having a size and shape suitable for its application (step 410). Preparation of the core structural layer may include painting one or more surfaces of the core structural layer. Next, a decorative graphic layer (e.g., layers 304, 308) is bonded to the top side, bottom side, or both top and bottom sides of the core structural layer (step 420). Each decorative graphic layer is bonded to the core structural layer using an adhesive or heat bonding process. If an adhesive is used, the adhesive may be sprayed on, brushed on, or applied in any other suitable manner.
Next, exterior finish layers (e.g., layers 302, 310) are applied to the externally visible surfaces of the core structural layer and decorative graphic layers (step 430). The exterior finish layers may be configured to come together along one or more edges, thus forming one or more seams. The seams may be finished according to known techniques in order to create a smooth transition. Once the exterior finish layers are completely applied, the exterior finish layers envelop the toilet lid or seat and provide a protective layer that resists wear and damage, but allows the decorative image or images to be seen.
