Abstract
Disposable liners for basins which can be removably attached to a basin to protect it from germs and other noxious agents in liquids within the basin.
Description
This invention relates to disposable liners for basins and more particularly to a disposable liner which can be removably attached to a basin to protect it from germs and other noxious agents in liquids within the basin.
It is an arduous and tedious job keeping wash basins (on the vanity) or kitchen sinks or laundry tubs, etc., hygienically clean. It is not only important, but can be vital, for wash basins in places like the hospital, laboratory, doctor's office, restaurant, etc.
There is a constant worry about the spread of germs (and, consequently, food poisoning, etc.) from an insufficiently cleaned basin, sink, etc. It is very often a losing battle, not only because of the invisibility (to the naked eye) and ubiquity of the germs, but also due to ignorance and sloppiness of food handlers and health care workers. Hence, "super infection" in hospitals, cross infections in doctors' clinics, and the euphemistic term "stomach flu" (in most cases, food poisoning) are entities that we come to live with as unavoidable nuisances. This present invention provides an important tool to combat, if not eradicate, such dangers.
It is an object of this invention to provide a disposable liner which may be removably attached to a basin to protect the basin from germs and other noxious agents in liquids within the basin.
Another object of the invention is to provide a disposable liner having a funnel through which liquid in the basin discharges, the funnel having a wall which expands to contact the wall of the drain to ensure that impurities in the liquid do not contact the basin.
The invention is described in detail with reference to the accompanying drawings in which:
Diagram A is a simplified plan view of the liner together with a basin;
Diagram B is a simplified section on line B-B of Diagram A;
Diagram C is simplified plan views of rings of various constructions through which liquid discharges from the basin;
Diagrams D and E are simplified perspective views of a funnel-shaped outlet through which liquid discharges and a portion of a sink;
Diagram F are two simplified perspective views of funnel-shaped outlets together with stoppers and portions of sinks; and Diagram G is a simplified perspective view showing the manner in which a funnel-shaped outlet is attached to the disposable liner and the manner in which the outlet is closed by a stopper.
The terms "wash basin" "basin" and "sink" are used in the generic sense to denote such plumbing fixtures as vanity basin, kitchen sink, laundry tub, bath tub, bidet, etc. The term "plastic" is used in a generic sense to denote various man-made/synthetic materials, such as, vinyl, polystyrene, etc.
Sinks and wash basins and such other fixtures are usually made of enameled metals or chinaware or porcelain, and rarely, of stainless steel or even, vinyl and such other materials.
Other than stainless steel, which is becoming quite popular lately, especially in public food and health care facilities, the materials which these sinks, etc. are made of often tend to chip or crack

2 a creating crevices that become the haven for bacteria. Even in stainless steel basins or sinks, bacteria ten to proliferate, in the nooks and corners and joint gaps.
In this present invention, an economical, handy and disposable liner is used on the wash basins, sinks, tubs, etc. This disposable liner is made of plastic or such other materials that are not porous to water and such other liquids used in such basins, etc.
As illustrated in Diagrams A and B, this disposable liner 10, herein called "Disposable Wash Basin Liner" or its acronym "DWBL" is placed on the sink or basin 12 covering the latter from the drain hole 14 in the center to the rim 16 in the periphery. This "DWBL" has a central opening 18 with a ring 20 ("Drainage Pipe of "DWBL"", in the said Diagrams) that sits into the drain hole opening 22 ("Drainage Pipe of the Sink" around the "Drain Hole", in the said diagrams) of the main or fixed sink or basin 12.
This "Drainage Pipe of "DWBL"" 24 is made of some rigid or semi-rigid material, such as plastic that is harder in consistency than the pliable sheet of the "DWBL"
and is molded or glued or attached or joined in any other fashion to the said pliable sheet of the "DWBL" (more or less like plastic carrying handle on a plastic shopping bag commonly available in the market).
This "Drainage Pipe of "DWBL"" may be manufactured in various sizes to fit into various sizes of "Drainage pipe of the Sink" available on the market, thus adding another dimension to the possible varieties (such as different colors or transparencies, different thicknesses, different consistencies or pliabilities, different grades of the material etc.) of the "DWBL". Or, this ring can be constructed in a manner that would give it the possibility of varying size within a certain latitude, as illustrated in Diagram C. Thus the outlet of the disposable liner is reinforced by the rlrlg.

Or, this ring can be constructed in a manner that would give it the possibility of varying size within a certain latitude, as illustrated in Diagram C. Thus the outlet of the disposable liner is reinforced by the rlrlg.
3 Diagrams D and E show other examples of adjustable "Drainage Pipe of "DWBL"", identified by the numeral 26. Here it is constructed in a funnel shape with a flat wide rim 28 of rigid or semi-rigid material, such as plastic, around the upper border 30. The idea behind the funnel shape is that it would fit into any size of openings 32 between the width of the narrow end 34 and the width of the wide end 36 of the funnel. And, the idea behind the above-mentioned "flat wide rim" is that this rim 28 would sit on and cover an opening 32 wider than the wide end of the said funnel so that the washing water would still be able to flow into the "Drainage Pipe of the Sink" 38 freely without coming into contact with the main or fixed sink 40 at all.
Also the lower or any part of the side of this "drainage pipe of DWBL"" 26 may be slit such as at 42 in Diagram C, the sections overlapping or separated etc in order to give the girth flexibility and adjustability in size, These slit or broken areas may also be jointed by some bellows-like device 44 in Diagram C, working like spring and also providing a water-tight barrier.
These are only some examples of the various ways of making the "Drainage Pipe of "DWBL"" of adjustable sizes, all these being within the purview of this present invention.
The "DWBL" 10 is secured on the periphery of the sink or basin 40 with some "Self adhesive" material 46 which is a part of the "DWBL" (and is covered with a layer of plastic or such material to be peeled off at the time of use) either as a continuous encircling line or in bits of small areas sufficient to secure the outer border of the "DWBL" 10 to the periphery of the sink or basin. The latter example with "bits of small areas" is illustrated in Diagram A. The "Adhesive Area of "DWBL"" shown in cross section in Diagram B and indicated 46a may represent either of these two examples. The said "continuous line" of adhesive is to be used in such cases as where it is necessary to prevent any possible leakage of water under the "DWBL" etc.

and the instance
4 of the "bits of small area" is to be used in such cases as where easy and handy application is preferred etc.
Since infectious or noxious agents may rest on the strainer in the drain pipe opening of the main or fixed sink or basin (therefore needing cleaning in ordinary cases) this strainer can be replaced with (or added to by) a strainer in the "Drainage Pipe of the "DWBL""
itself. This strainer is not shown in the Diagrams here.
The "DWBL" has a disposable stopper ~Q ("Disposable Stopper for "DWBL"" in Diagram B) that, when desired, closes the opening of the "Drainage Pipe of "DWBL"".
This disposable stopper may be made of some inexpensive material such as plastic.
Another part of this present invention as illustrated in Diagram F and G is an inexpensive and handy-to-use outlet/ opening nozzle or ring 52, made of plastic or such other material, truncated conical in shape, with rough and/or corrugated and/or sharp beveled edge 54 at the lower and narrower end capable of piercing through a pliable sheet of plastic 56 or such other material laid on the inner surface of a sink or basin or such other plumbing fixtures and thus fixing or anchoring the edge of this pierced hole of the said plastic sheet on to the drainage pipe opening 58 of a sink etc. With this device one can use any ordinary plastic or such other sheet to improvise, so to say, a disposable liner of a sink, etc. This said nozzle or ring may host another coupling nozzle or ring 60 (Diagrams F and G) with one or no open end, and of a just smaller size to act as a stopper for the first nozzle or ring 52. Another improvement on this improvisation is to have the host 52 as well as the coupling nozzles 60 or rings provided with corresponding holes 64, 66 respectively arranged in such a manner that any two of the said corresponding holes may lie against each other allowing liquid (with any small enough solid particles) to pass but when one A
of these nozzles or rings is rotated slightly but sufficiently and just sufficiently as illustrated at 70 in Diagram F all the holes of one nozzle or ring will be covered by the solid part of the plate of the other nozzle or ring thus one of these nozzles or rings acting as a stopper for the other nozzle or ring and consequently allowing no liquid (with any solid particle, of course) to pass.
This allows the said liquid to pass on to the drain when any part of the top part of the nozzles or rings protrudes above the most depended part of the sink etc.
especially around the "Drainage Pipe of the Sink" because of the latter being too small to allow the whole (including the said top part) of the nozzles or rings to be inserted inside it. Like the holes on the plate at the end of the nozzle or ring, these said holes on the sides of the nozzles or rings need to be arranged in such a manner as described above that they, by apposition, allow liquid and small enough solid particles to pass but when overlie the solid parts of the other nozzle or ring do not allow this said liquid etc to pass.
