Description

PLASTIC SINK, TOILET BOWL, URINAL,

BATH TUB, DRINKING FOUNTAIN MODULES

BACKGROUND OF THE INVENTION

1. TECHNICAL FIELD

[0001] The present invention relates to sinks, toilet bowls, urinals, bath tubs, and drinking fountains. In particular, the present invention relates to sinks, toilet bowls, urinals, bath tubs, and drinking fountains made of plastic.

2. BACKGROUND ART

[0002] Many sinks, and other fixtures including toilet bowls, urinals, bath tubs, and drinking fountains, are made of ceramic. Typically, these ceramic articles are composed of feldspar and quartz ground and combined with China clay, ball clay and talc, which have been combined in requisite proportions to form a slip. To construct these articles, the slip is cast in a mold of the desired shape, dried, bisque fired, coated with glaze, and fired again.

[0003] There are several drawbacks to constructing sinks and other fixtures of ceramic materials. Ceramic fixtures are very heavy, due to the density of ceramic and to the heavy wall required to manufacture it. Ceramic fixtures are manufactured in only a single color. Ceramic fixtures are brittle. During handling or installation if a fixture falls to the floor or hits a hard surface, it can shatter and potentially cause injury to a person or worker. The design freedom of ceramic fixtures is very limited due to the manufacturing process used. Ceramic fixtures cannot be manufactured with integrated components such as quick connectors for a water drain. Therefore, there is a need for sinks, toilet bowls, urinals, bath tubs, and drinking fountains that can overcome each of the above disadvantages.

SUMMARY OF THE INVENTION

[0004] The present invention provides for a sink including a plastic basin, at least one water faucet opening along a rim, and a drainage opening at a bottom portion of said plastic basin.

[0005] The present invention provides for a method of making a plastic sink by injection molding at least one plastic layer, and forming a plastic sink.

DETAILED DESCRIPTION OF THE INVENTION

[00046] The present invention provides a sink 10 of plastic construction including a basin 18. The basin 18 is bordered at least partially by a rim 14 including at least one water faucet opening 12. A drain opening 16 is provided at the bottom of the basin 18 as shown in FIGURES 1A-1 D.

[00047] The sink 10 can be made to be of any size desired. Any suitable plastic can be used that can be molded to the required form, such as a polymer or elastomeric material. Preferably, the plastic is the thermoplastic polybutylene teraphthalate (PBT), but other polymers can be used, including, but not limited to, polyethylene, polypropylene, polycarbonate, and polyacetal.

[00048] The sink 10 includes one or more layers 100. A single-layered sink is preferably constructed of PBT. Preferably, the sink 10 is multilayered, that is, it includes a plurality of plastic sublayers. For example, a three-layered sink can include an inner sublayer 102, an intermediate sublayer 104, and an outer sublayer 106, as shown in FIGURES 2A and 2B.

[00049] In an exemplary configuration of a three-layered sink, the inner sublayer 102 is composed of polybutylene terephthalate (PBT), most preferably high density PBT formulated to resemble a ceramic in appearance and textu e. The outer sublayer 106 is preferably composed of a thermoplastic elastomer (TPE). The intermediate sublayer 104 is preferably composed of medium to low density PBT, including recycled PBT.

[00050] High density PBT is preferred for the inner sublayer because of its ceramic appearance, high surface gloss, scratch resistance, chemical resistance, including resistance to acids, bases, and solvent, and resistance to discoloration by common food and cosmetic products. High density PBT can be injection molded into many shapes, has good dimensional stability, and can accept color and decoration.

[00051] A TPE is preferred for the outer sublayer 106 because of its known shock resistance. The outer sublayer 106 is the layer most likely to be subjected to shock, especially during the processes of transport and installation.

[00052] The intermediate subayer 104 is optionally foamed, as shown in FIGURE 2B. Foaming of the intermediate sublayer 104 provides insulation, reducing heat loss from water contained in the basin 18 and preventing user discomfort from contact with a hot basin 18. Foaming also reduces the overall weight of the sink 10. The foaming agent can include an exothermic or endothermic blowing agent. Alternatively, an inert gas such as nitrogen can be incorporated. In addition, any or all of the sublayers 102, 104, and 106, and any additional sublayers (not shown), can be foamed, or all of the sublayers can be unfoamed,

[00053] The plastic composition of any or all of the sublayers 102, 104, and 106, and any additional sublayers (not shown) can include a filled plastic. The filler can include, but is not limited to, glass fibers, carbon fibers, metal fibers, aramide fibers, nanoclays, talc, CaCOs, or any combination thereof. The plastic composition of any or all of the layers 102, 104, and 106, and any additional sublayers (not shown) can include recycled plastic.

[00054] In a sink 10 including a plurality of sublayers, at least one adhesive layer (not shown) can be included to improve bonding between adjacent sublayers. In the example shown in FIGURE 2B, for instance, the intermediate layer 104 can be replaced with an adhesive layer (not shown). Alternatively, bonding between sublayers can be accomplished without adhesive, by overmolding sublayers of appropriate composition, and under appropriate conditions, to achieve a chemical or physical bond between layers. For examples, two adjacent layers of PBT are known to self-bond under appropriate conditions.

[00055] Preferably, the sink 10 is manufactured by injection molding, and a sink including more than one plastic layer is manufactured by progressive insert injection overmolding. A sink 10 including a plurality of plastic sublayers can for example be manufactured by injection molding an inner sublayer 102, placing the inner sublayer 102 into a larger injection mold of suitable size and shape, and casting an additional sublayer about the inner plastic sublayer. Additional sublayers can be added by performing similar steps. In addition, additional sublayers can be cast separately and bonded together.

[00056] The sink 10 or any sublayer thereof can include at least one additive to enhance the functionality of the sink 10. For example, any or all sublayers can include a UV stabilizer to improve the durability of the sink 10, in locations exposed to UV light. Any or all sublayers can include a flame retard ant. Any surface exposed to physical contact, such as the inner layer 102, can include a scratch resistant coating. Any or all of the sublayers can include one or more antimicrobial compounds, such as an antibacterial compound, an antifungal compound, an antialgal compound, or any combination thereof. For example, a silver based antimicrobial can be incorporated, but such compounds tend to cause discoloration. More preferable is a silane-based antimicrobial such as Biosafe®, for example at a concentration of 0.5 - 1 .0% in the final product. Silane-based antimicrobials have the advantage of being non-toxic and non-volatile. They do not encourage resistance, since they act by physical disruption of microbes. Silane-based antimicrobials are compatible with many types of plastic and tend not to cause discoloration. The foregoing does not constitute an exhaustive list of additives, and any additive which enhances the functionality of the sink 10 is within the scope of the present invention.

[00057] The sink 10 includes at least one faucet opening 12 sized to accommodate various faucet designs. For example, multiple faucet openings 12 can accommodate separate hot and cold water handles and/or a sprayer as well as faucet. A single faucet opening 12 can be used when the faucet includes a hot/cold water knob or lever. The faucet openings can include an integrated seal (not shown).

[00058] The rim 14 can surround the entire basin 18. This configuration is desirable for a sink 10 intended to rest on a countertop when installed. The rim 14 can be of any size desired. The drain opening 16 allows for quick connection to pipes and can be threaded. The drain opening 16 can be of any size [00059] The sink 10 also preferably includes a water overflow opening 20 near a top portion of the basin 18 to allow water to drain out of the basin 18 before overflowing. A water overflow channel 22 can be attached to the sink 10, extending from the water overflow opening 20 to the drain opening 16, as shown in FIGURES 1 D, 3A and 3B. The water overflow channel 22 includes a channel drain opening 24 that aligns with the drain opening 16 on the sink 10 when attached to the sink 10. Essentially, the water overflow channel 22 conforms to the shape of the sink 10 while allowing water to flow from the water overflow opening 20 down the channel 22 into the channel drain opening 24 and out through a pipe. When the water overflow channel 22 is in place, water flowing out of a faucet enters the basin 18, drains through the drain opening 16, through the channel drain opening 24 of the water overflow channel 22, and then out through a pipe. The water overflow channel 22 includes edges 26 that abut the basin 18 to ensure that water does not leak out of the water overflow channel 22.

[00060] The water overflow channel 22 is preferably of plastic construction. It can, for example, be made of a single layer of PBT, but it can alternatively include multiple layers of various filled and unfilled, foamed or unfoamed plastic, with or without functional additives, as previously described in connection with the sink 10. The water overflow channel 22 can be manufactured by molding, such as injection molding and lost core molding, it can be attached to the sink 10 by ultrasonic or vibration welding, by any suitable adhesive known in the art, or by any combination thereof. [00061] In an alternative embodiment, the water overflow opening 20 includes a connector opening 28 and the drain opening 16 extends slightly below the sink 10 and includes another connector opening 28 to which a hose (or tube) 30 can be connected thereto. In other words, overflowing water flows into the water overflow opening 20, down the hose 30, and into the drain opening 16 of the sink 10. This embodiment is shown in FIGURES 4A-3D and 5A-4C. The connector openings 28 receive connection fittings 32 to hold the hose 30 in place. Alternatively, the connector openings 28 can have integrated connection fittings or barbs 33 so that a separate connection fitting 32 is not required, as shown in FIGURES 6A-6B.

[00062] The sink 10 of the present invention can accommodate any type of water faucet handle and faucet known in the art. Preferably, the water faucet handle and faucet are the innovative plastic faucet handle 108 and faucet 1 10 also provided by the present invention. The faucet handle 108 includes a handle core 1 12 surrounded by an outer handle layer 1 4, examples of which are shown in FIGURE 7B. The surface of the outer handle layer 1 14 optionally includes metal plating 1 16, preferably chrome plating Alternatively, the outer handle layer 1 14 is painted or is less preferably left unfinished (not shown). The handle core 1 12 is preferably composed of polyphthalamide (PPA) or polyphenylene sulfide (PPS). Both plastics possess excellent heat resistance, which is advantageous for components exposed to hot water. The outer handle layer 1 14 is preferably composed of an acrylonitrile- butadiene-styrene (ABS) plastic, a type which is heat stable and which accommodates metal plating. Prefera ly, the inner handle core 1 12 is chemically bonded to the outer handle layer 1 4, but bonding can be alternatively achieved with a suitable adhesive. Under appropriate conditions, PPA or PPS form a chemical bond with ABS. Alternatively the handle core 1 12 and outer handle layer 1 14 can be composed of any suitable plastic. Preferably the plastic compositions of both the handle core 1 12 and the outer handle layer 1 14 are foamed, to insulate a user from high temperature and to reduce the overall weight of the assembly of the sink 10 and its associated components. Alternatively, either or both the handle core 1 12 and the outer handle layer 1 14 can be unfoamed. The plastic compositions of the handle core 1 12 and the outer handle layer 1 14 can be either filled or unfilled, as described previously in connection with the sublayers of the sink 10.

[00063] The faucet 1 10 is preferably of a construction similar to that described for the faucet handle. That is, the faucet 1 10 preferably includes a faucet core (not shown), preferably of PPA or PPS which can be either foamed or unfoamed and filled or unfilled; an outer faucet layer (not shown), preferably composed of ABS, which can be foamed or unfoamed and filled or unfilled; and an optional metal plating (not shown), preferably of chrome.

[00064] The faucet handle 1 10 is preferably manufactured by injection molding the handle core 1 12, placing the handle core into a larger injection mold of suitable size and shape, insert injection overmolding the outer handle layer 1 14, and chrome plating or painting the surface of the outer handle layer 1 14. The faucet 1 10 is preferably manufactured by injection molding the faucet core (not shown), placing the faucet core (not shown) into a larger injection mold of suitable size and shape, insert Injection overmolding the outer faucet layer (not shown) and finally chrome plating or painting the surface of the outer faucet layer (not shown). [00065] Although an integrated faucet-faucet handle assembly is disclosed in the previous example, a faucet 1 10 and two or more separate faucet handles 108 can alternatively be provided as separate units.

[00066] The sink 10 of the present invention can accommodate any type of spray attachment known in the art. The spray attachment is preferably the innovative plastic spray attachment 118 also provided by the present invention. An exemplary spray attachment is shown in FIGURE 8A and 8B. The spray attachment 1 18 includes a tubular spray handle core 120, a spray head core 122 in fluid communication with one end of the spray handle core 120, and a tubular outer spray handle 124 enclosing at least the spray handle core 120 and preferably also enclosing at least a proximal portion of the spray head core 122. The surface of the outer spray handle 124 optionally includes metal plating 1 16. The spray head core 122 can be an integral component of the spray handle core 120, or alternatively it can be a separate component attached to the spray handle core 120. One or more sprayer components 126 such as an aerator can be attached to the spray head core 122 by any means known in the art. A hose stem 128 can be included at the end of the spray handle core 120 opposite to the spray head core 122. The hose stem 128 can either be included as an integral component of the spray handle core 120, or alternatively can be included as a separate component attached to the spray handle core 120.

[00067] The spray handle core 120 and spray head core 122 are preferably composed of polyphthalamide (PPA) or polyphenylene sulfide (PPS). Both plastics possess excellent heat resistance, which is advantageous for components exposed to hot water. The outer spray handle 124 is preferably composed of an acrylonitrile- butadiene-styrene (ABS) plastic, a type which is heat stable and which accommodates metal plating. Alternatively the spray handle core 120 and outer spray handle 124 can be composed of any suitable plastic. Preferably the plastic compositions of the spray handle core 120, the spray head core 122, and the outer spray handle 124, are foamed, both to insulate a user from high temperature and to reduce the overall weight of the assembly of the sink 10 and its associated components. Alternatively, any or all of the plastic compositions of the spray handle core 120, the spray head core 122, and the outer spray handle 124, can be left unfoamed. The plastic compositions of spray handle core 120, the spray head core 122, and the outer spray handle 124 can be either filled or unfilled, as described previously in connection with the sublayers of the sink 10. Preferably, the spray handle core 120 and spray head core 122 are chemically bonded to the outer spray handle 124, but bonding can be alternatively achieved with a suitable adhesive. The spray handle core 120 and outer spray handle 124 can also be mechanically interlocked, for example by means of hardware associated with the hose stem 128.

[00068] The spray attachment 1 18 is preferably manufactured by injection molding the spray handle core 120 and the spray head core 122 as a single unit, placing the spray handle core 120 and spray head core 122 into a larger mold of suitable size and shape, insert injection overmolding the outer spray handle 124, and finally chrome plating or painting the surface of the outer spray handle 124. Alternatively, the spray head core 122 can be injection molded separately and attached to the spray handle core 120 prior to overmolding of the outer spray handle 124. In another alternative, the outer spray handle 124 can be separately injection molded and mechanically attached to the spray handle core 120 and the spray head core 122.

[00069] The sink 10 can be made in various colors and it can include various designs or logos 130, as shown in FIGURES 9, 10A-10B, and 11A-1 1 C. A company logo or a design, for example, can be incorporated anywhere desired on the sink 10, such as the basin 18 or the rim 14. The water overflow channel 22 can also be made in colors and designs to match the sink 10. Because the sink 10 is made of plastic, many more design options are available for customization than are currently available for other types of sinks. As one example, the plastic can be colored to resemble porcelain or granite (not shown). As another example, portions of the sink can be colored before or after molding, to create a patterned color effect, an example of which is shown in FIGURES 1 1 A-C. As another example, phosphorescent compounds can be incorporated or applied to the sink 10 to produce a "glow in the dark" effect. The phosphorescent compounds can be added to the plastic composition of one or more sublayers o the sink 10 before or after molding, so that an entire sublayer or a designated portion thereof glows in the dark. Alternatively, phosphorescent compounds can be incorporated into the logos and designs 130 that are incorporated into the sink 10 (not shown). The faucet 110, faucet handle 108, and spray attachment 1 18 of the present invention can also include colored and phosphorescent plastic compositions, logos, and designs. The preferred phosphorescent compounds include phosphorescent pigments based on strontium oxide aluminate chemistry, which can produce a visible glow for up to 12 hours after exposure to visible light. The LumiNova® lines of pigments are exemplary strontium oxide aluminate phosphorescent compounds (Tavco Chemicals, Laguna Hills, CA).

[00070] The sink 10 of the present invention overcomes many of the limitations of ceramic sinks besides design options. The plastic sink 10 is lightweight, easy to manufacture, it can withstand being dropped during installation, and it can be manufactured with various components already integrated, such as the connection fittings 32 described above.

[00071] Also provided by the present invention are toilet bowls, urinals, bath tubs, and drinking fountains of plastic construction. The design of each of these modules includes a single plastic layer or a plurality of sublayers similar or identical to those previously described in connection with the sink 10, in terms of composition, arrangement, functional additives, coloration, ornamentation, and method of manufacture. Each of these modules can also include water overflow openings 20 and water overflow channels 22 and/or connector openings 28 and hoses 30 as described for the sink 10, to remove overflowing water from the modules.

[00072] The present invention provides a plastic toilet bow! 50 (shown in FIGURE 12). The plastic toilet bowl 50 includes any necessary drainage openings that can be threaded for quick connection, and generally includes a base 52 including a seat 54 and lid 56 pivotably connected thereto.

[00073] The present invention provides a plastic urinal 60 that can include an integrated splash guard 62 (FIGURES 13A-13C). The integrated splash guard 62 can be made of the same material and color as the plastic urinal 60, or of different materials and in different colors. The splash guard 62 can be snap-in replaceable, with or without a seal. The plastic urinal 60 also includes any necessary drainage openings or inlets 64 and can include threading for quick connection.

[00074] The present invention provides a plastic tub 70 including openings for water faucets or drainage, which can be threaded as necessary. The plastic tub 70 can include integrated water faucets 72 as shown in FIGURE 14. Alternatively or in addition, the plastic tub 70 can include a faucet 1 10 faucet handles 108, and a spray attachment 118 as previously described in connection with the sink 10. The plastic tub 70 can also include an integrated slip guard 74 that is made of the same material and color as the plastic tub 70, or of different materials and in different colors, and can be snap-in replaceable with or without a seal.

[00075] The present invention also provides for a plastic drinking fountain 80, which can be wall-mounted, stand-mounted, or floor-mounted as a fountain for pets, as shown in FIGURES 15A-15C. The plastic drinking fountain 80 includes openings for water faucets/inlets or drainage, which can be threaded as necessary. The plastic drinking fountain 80 can also include a faucet 110 and faucet handles 108 as previously described in connection with the sink 10. The plastic drinking fountain 80 can include an integrated splash guard 82 that is made of the same material and color as the plastic drinking fountain 80, or of different materials and in different colors, and can be snap-in replaceable with or without a seal.

[00076] Each of the plastic modules of the sink 10, plastic toilet bowl 50, plastic urinal 60, plastic tub 70, and plastic drinking fountain 80 of the present invention are easy to install due to their light weight, and are more resistant to shock than ceramic toilet bowls, urinals, tubs, and drinking fountains. Each module can be molded to include one or more non-phosphorescent or phosphorescent colors, various logos and designs can be molded directly in the plastic, and the plastic can be colored to resemble porcelain or granite.

[00077] The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.

[00078] Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that the invention may be practiced otherwise than as specifically described.
