Abstract
An aim of the invention is to provide a simple and effective one-piece tap which can be readily and economically manufactured. A tap for a liquid container is made from natural or synthetic rubber or a resilient plastics material. It has a base portion 10 having an orifice 12 which serves as a liquid inlet therein, the base portion embodying a liquid exit means 14. It also has a resilient deformable closure portion 20, the closure portion being constructed to make a resilient snap-on connection with the periphery of the base portion, the closure portion being manipulatable and having a centrally located plug 22 extending towards the base portion. This plug can obturate orifice 12 thereby closing the liquid inlet.
The closure portion 20 also has a projecting portion 23 extending generally perpendicularly away from the base portion, the projecting portion being constructed so that it can be pushed towards the base portion in order to remove the plug from the orifice and so permit liquid to pass to the liquid exit means 14.
The closure portion 20 also has a projecting portion 23 extending generally perpendicularly away from the base portion, the projecting portion being constructed so that it can be pushed towards the base portion in order to remove the plug from the orifice and so permit liquid to pass to the liquid exit means 14.
Description
A TAP OR VALVE
This invention relates to a tap or valve and particularly although not exclusively to a tap for a urostomy pouch.
Various designs of taps or dispensing spigots have been proposed. See for examaple Fattori et al U.S. Patents Nos. 3,400,866 and 4,787,538, Welsh U.S.
Patent No. 3,972,452, European Patent Application No. 95861A and Scholle U.S.
Patent No. 4,211,348. These designs, in the Applicants' opinion, fall short in that tliey are lacking in simplicity. Most are completely unsuitable for employment in a urostomv pouch.
It is an aim of the invention to provide a simple and effective easily-assembled tap which can be readily and economically manufactured.
AccordinQ to tlie invention there is provided a tap for a liquid container, -nade trom natural or synthetic rubber or a resilient plastics material, which is comprises a base portion having an orifice wilich serves as a liquid inlet therein, the base portion embodying a liquid exit meails. and a resilient deformable closure portion. the closure portion being constructed to -nake a resilient snap-on connection witli the periphery of the base portion, the closure portion being manipulatable and having a centrally located plug extending towards the base portion which can obturate said orifice thereby closing the liquid inlet, the closure portion also having a projecting portion extending generally perpendicularly away from the base portion, the projecting portion being constructed so that it can be pushed towards the base portion in order to remove the plug from the orifice and so permit liquid to pass to the liquid exit means.
In a preferred embodiment of the invention, the closure portion is a wall which is generally oval in shape as seen in front elevation and has an external thickened sloping portion upon wliich the said plug is internally mounted. The sloping portion is located generally centrally of the closure portion. In the embodiment of the invention which consists of a urostomy pouch, the base portion including the liquid exit means thereof is constructed for attachment, e.g. by heat or R.F. welding, to one wall of the pouch, the pouch having an aperture in one of its walls, the aperture being in registry with the liquid inlet orifice.
In an advantageous embodiment of the invention, a night drainage adapter may be used with, and temporarily incorporated in, the tap described and illustrated herein. This adapter device comprises a tube extension of a particular shape which when inserted into the liquid exit means, holds the closure portion away from the liquid entry hole in the base portion. This permits intermittent night drainage to occur, with no manipulation to open the tap being necessary.
The invention will be better understood from the following description of an io illustrative embodiment, in which like parts are represented by like reference numerals, and in which:-Figure 1 is a front view of one example of tap according to the invention;
Figure 2 is a cross-section on the plane II-II in Figure 1 showing the tap in its open condition and diagrammatically illustrating part of a wall of a urostomy pouch;
Figure 3 is a view identical to Figure 2 but showing the tap in its normally closed condition;
Figure 4 is a cross-sectional view of a tap having a night drainage adapter in place; and Figure 5 illustrates an optional refinement in the form of a peripheral groove on the drain tube, which allows attachment of a known type of tube connector (see UK Patent 2,092,690;\EP 57057B ).
Referring to Figures 1-3, the illustrated tap comprises a base portion 10 and a closure portion 20. The wall of a urostomy pouch which is the currently preferred example of product in which the tap may be employed, is shown at 30 in Figures 2 and 3.
The base portion 10 comprises a central orifice 12 and embodies a liquid exit means 14. The base portion has a peripheral wall 16, and carried by this wall is an outwardly extending rim 17 provided to enable snap-on engagement between itself and a connection means 21 on the periphery of the closure portion 20. The base portion 10 lias a flat surface l0A which may be plastics welded or adhesively secured or fastened in any other convenient way to the wall 30 of the liquid container.
The peripheral snap-on connection means 21 of the closure portion is designed to co-operate with the peripheral wall 16 of the base portion. The closure portion is made of a resilient deformable material, preferably a thermoplastics elastomer. The closure portion has a centrally located plug 22, which extends towards the base portion 10 and is shaped to make a complementary mating engagement with the wall 12A of the orifice 12. The closure portion has a peripheral slot 18, in which is received the wall 16.
The left-hand end as seen in Figure 2 or Figure 3 of the base and closure portions will be uppermost in use of the tap, with the liquid exit means 14 being lowermost.
The closure portion 20 is a plastics moulding, and has a thickened portion which in the closed position of the tap is at an angle to the'vertical and in the tap's open position occupies an approxiinately vertical position. This may be achieved by manipulating the closure portion 20 witli a finger as illustrated in Figure 2. This manipulation is faciliated by the fact that the thickness of the closure portion is substantially reduced at the zones 24 and 25 and is reduced but to a lesser extent at the zone 26. The zones 24 and 25 readily deform to enable the closure portion to take up its open position as illustrated in Figure 2.
One desirable advantage of this design of tap is that its overall thickness is small. Hence, a pouch having this design of tap is unobtrusive when worn.
Another advantage is that the closure portion 20 immediately reverts to the closed position as seen in Figure 3 when the finger pressure is removed from the portion 23 thereof. The complementary shaping of the plug 22 and the wall 12A, and the interfit between the parts 16, 17, 18, assist in achieving a durable and leakproof fit.
The tap as illustrated in Figures 1-3 has no detachable parts which might become misplaced or lost.
A night drainage adapter 40 is illustrated in Figure 4 in position within the tap. The adapter 40 comprises a tapered tube having a ribbed end 42, a flange 44, a taper 46 at its upper end in use, and a hole 48 of a size slightly greater than the holle 12 in the base portion 10. The ribbed end 42 facilitates connection to a drain tube 50. As will be seen in Figure 4, the adapter 40 when inserted upwardly into the tap, forces the closure portion away from the base portion 10. The resilience of the closure portion holds the adaptor 40 into close engagement with the surface of the base portion. Liquid entering via hole 12 is then guided by adapter 40 directly to the train tube 50.
Referring now to Figure 5, at the lower end of the drain tube 50 a peripheral io groove 52 is provided, to receive hook members 54 of a known connector, provided to convey liquid, e.g. to a night drainage bag or reservoir.
This invention relates to a tap or valve and particularly although not exclusively to a tap for a urostomy pouch.
