Definitions
- the present invention relates generally to filters for use in conjunction with valves of the faucet or spigot type, and particularly to filters for use in devices for withdrawing liquids from beverage containers at relatively low pressures, such as water coolers, wine barrels and the like.
- An object of the invention is to provide a novel means for filtering beverages as they are dispensed for consumption.
- a further object of the invention is to provide an improved filter mechanism and filter element for use in dispensers of bottled water whereby the filter element is easily insertable in and detached from the remainder of the assembly for quick replacement.
- Another object is to provide a filter mechanism which also functions as a fastener for mounting a dispensing valve or spigot to a reservoir.
- Yet another object is to provide a novel filter element.
- a valve and filter for filtering and dispensing a beverage from a reservoir comprises a spigot adapted to be mounted to the reservoir to dispense liquid therefrom, a filter receiving means adapted to receive a filter element to filter the beverage passing through the spigot, said filter receiving means being mounted to said valve and constructed and arranged so that liquid to be dispensed from said valve passes through a filter element mounted in said filter receiving means, and a filter element having a complementary configuration to that of the opening of the filter receiving means, said filter receiving means and filter element being constructed and arranged so that the filter element can be push-fitted into the filter receiving means.
- the filter element comprises a hollow shell having a complementary configuration to that of filter receiving means and constructed and arranged to be push-fitted into said filter receiving means, apertured end plates enclosing said hollow shell, and filter material carried within the enclosure defined by said apertured end plates and hollow shell.
- Fig. 1 is a side elevational view of a water bottle and reservoir assembly partially broken away to show the filter mechanism and valve assembly of the present invention
- Fig. 2 is a sectional view of the filter mechanism of the invention taken along line 2-2 in Fig. 1;
- Fig. 3 is a partially sectional view of the filter element end plate in accordance with the invention taken along line 3-3 of Fig. 2;
- Fig. 4 is an exploded view of the elements of the filter mechanism.
- inverted water bottle 10 is mounted on reservoir 12 to deposit the water carried by bottle 10 in reservoir or cooler 12, from whence it is dispensed through a valve 14 of the spigot or faucet type.
- a filter mechanism in accordance with the invention indicated generally at 16 is provided at the inlet of spigot 14 (in the manner to be described below) so that all water dispensed from the reservoir 12 through spigot 14 passes through the filter mechanism 16.
- the filter mechanism 16 is shown in greater detail in Figures 2 and 4 as comprising generally a filter receiving means 18 and filter element 20.
- the filter receiving means 18 desirably is an open-ended, cup-shaped member and the filter element 20 can be "push fitted" into the filter receiving means 18.
- the filter element 20 has a cylindrical configuration which complements the contours of the cupshaped member 18, but it should be appreciated that a wide variety of complementary configurations will suffice.
- the dimensional size of the opening of filter receiving means 18 is preferably almost identical to the size of the exterior of filter element 20.
- Means are preferably provided for holding the elements 18 and 20 snugly together in response to insertion of the filter element 20 into the receiving 18.
- this is ac hieved by tapering at least one of the two mating surfaces, the periphery of the filter element 20 and the inner complementary cylindrical (as shown) surface of the receiving means 18.
- a taper that has been found to be effective is a taper on the order of 1° to the peripheral surface 20a of filter element 20 so that the small diameter end of the filter element 20 enters the receiving means 18 easily while the portion of peripheral surface 20a last entering the receiving means 18 fits snugly against the inner surface 18a of the receiving means 18 to hold the filter 20 in place.
- the filter 20 can be "push-fitted” into the receiver by merely pushing it longitudinally into the complementary portion of the receiving means.
- the filter mechanism is preferably constructed and arranged (as shown) so that the water flow through it tends to urge the elements 18 and 20 together in the direction of the push fit.
- the filter mechanism 16 mounted to the inlet of the water spigot 14 in the following manner.
- the inlet of the water spigot 14 is defined by the interior of an externally threaded pipe member 22 which passes through hole 24 formed in the reservoir wall.
- Enlarged shoulder 26 positions the spigot 14 against the exterior wall of the reservoir and the filter receiving means 18 also serves to mount the spigot 14 by virtue of the threaded hole 28 formed in the closed end of cup-shaped member 18 which is adapted to engage the threads on pipe 22.
- a washer 30 is placed between the filter receiving means 18 and the interior wall of the reservoir 12. The filter mechanism and water spigot assembly may thus be quickly mounted to the reservoir by inserting the pipe 22 through a hole in reservoir 12, the washer 30 placed on the stem of pipe 22, the member 18 screwed onto the pipe 22 to act as a nut to mount the spigot, and the filter element 20 is "push-fitted" into receiving means 18.
- the filter element 20 preferably comprises a cup-shaped member 32, desirably of plastic material, which forms the peripheral wall 20a and one end wall of the element 20.
- the open end of the member 32 is closed by end plate 34 which is pressed into the element 32 and held in place by bead 36.
- End walls 34 and 32' are apertured preferably with a plurality of relatively small apertures arrayed in a regular mesh pattern (see Fig. 3).
- the filter element preferably includes filter paper 38 and 38' adjacent the inside surfaces of apertured end plates 34 and 32', respectively, and the intreior of the filter element preferably contains activated charcoal indicated at 40.
- the dispenses water passes (generally in the direction of the arrows 42 in Fig.2) through apertured plate 34, filter paper 38, activated charcoal 40, filter paper 38' and apertured plate 32' before it is to be consumed.
- This direction of flow also urges the filter element 20 and receiving means 18 into a press fit relationship.

Abstract
Element filtrant monte sur l'orifice d'admission d'un robinet (14) de distribution de boissons d'un reservoir ou d'un refrigerateur (12). Les filtres des distributeurs de boissons anterieurs etaient difficiles a remplacer. Le mecanisme de filtre decrit comprend de preference un organe ouvert (18), en forme de cuvette, qui est visse convenablement autour de l'arbre de l'orifice de sortie (22) du robinet pour servir de fixation pour le montage du robinet sur le reservoir. L'element filtrant (20) peut etre introduit et extrait rapidement du moyen de retention du filtre (18) par un calage a la presse. L'element filtrant prefere comprend deux parois exterieures pourvues d'ouvertures (34 et 32'), du papier filtre (38) positionne immediatement adjacent a la face interne de chaque paroi exterieure pourvue d'ouvertures, et du charbon actif (40) entre le papier filtre.
