Definitions
- This invention relates to a water treatment cartridge for use in domestic water treatment apparatus such as a water filter jug, to apparatus for carrying such a water treatment cartridge in a receptacle and to domestic water 0 treatment apparatus, in particular, a water filter jug for fitting with such a water treatment cartridge.
- Water filter jugs usually comprise a removable hopper which is supported on the brim of the deep vessel that is formed by the jug.
- the hopper is adapted to carry a water 5 filter cartridge which typically comprises a moulded container having inlet and outlet slots formed therein to allow water to enter and exit an internal cavity which contains water treatment medium.
- the cartridge In use, the cartridge is located in the hopper so that 0 the inlet slots open into a chamber formed by the interior of the hopper and the outlet slots open into the vessel below the hopper. Hence when unfiltered water is poured into the hopper, it flows through the cartridge where it is purified and then out from the cartridge into the vessel. 5
- the cartridge and the water treatment medium are such as to ensure that the dwell time of water in the cartridge is sufficient to provide adequate purification.
- the water treatment medium used in such cartridges typically comprises a particulate filter and may also
- a water treatment cartridge for use m domestic water treatment apparatus such as a water filter jug, the cartridge being as claimed m claim 1.
- Preferred features of the water filter cartridge are claimed in claims 2 to 7.
- domestic water treatment apparatus in particular, a water filter jug, fitted with a water treatment cartridge according to said one aspect of this invention wherein the removable covering means of the cartridge have been removed.
- a reticulated screen typically a mesh
- the mesh may be made from filaments of metal or a suitable plastic material and may have an interstice size in the ranqe 50 micrometers - 300 micrometers, preferably 80 micrometers to 200 micrometers.
- An advantage of the water filter cartridge of the present invention is that the water treatment medium is maintained in a moist condition until required for use, without the need for costly and bulky packaging.
- Figure 1 is a transverse cross section of a water filter jug with a hopper fitted therein and supporting a water filter cartridge, the hopper and the cartridge being shown in elevation apart from the part of the hopper that supports the cartridge which is cut away to reveal the lid of the cartridge and which is shown in section;
- Figure 2 is a view of the lid of the cartridge and of the surrounding portion of the hopper as seen on arrow A on Figure 1;
- Figure 3 is a section on line III-III in Figure 2;
- Figure 4 is a view similar to Figure 3 showing the opening at the base of a hopper adapted to receive another form of water filter cartridge;
- Figure 5 is a partly section side elevation of the water filter cartridge to be fitted into the hopper opening shown in Figure 4 in condition for storage.
- FIG. 1 shows a water filter jug 10 which has a hopper 11 fitted into it.
- the hopper 11 is generally cup-shaped, having a cylindrical side wall 12, a base 13 and an outwardly-extending peripheral flange 14 formed around its brim.
- the hopper 11 is supported within the interior of the deep vessel formed by the water jug 10 by having its peripheral flange 14 seated upon the brim of that vessel.
- the base 13 of the hopper 11 slopes radially- inwardly, away from the flange 14 and to an opening 15 at its center.
- the opening 15 is formed by a tubular portion 16 which is integral with and which extends from the base portion 13 away from the flange 14.
- the end of the tubular portion 16 remote from the flange 14 forms a radially- inwardly directed flange 17.
- a spiral groove 18 is formed in the bore of the tubular portion 16 between the base portion 13 and the inwardly directed flange 17.
- the flange 17 provides an annular seat for a radially- outwardly extended peripheral flange 19 which is formed around the brim of a cup-shaped receptacle 21.
- the receptacle 21 has a side-wall 22 which tapers to a base 23.
- Figure 3 shows the base 23 has an opening 24 formed in it and the opening 24 is covered by a reticulated screen 25, such as a mesh.
- the receptacle 21 contains water treatment medium 26.
- the upper end of the receptacle 21 is open and serves as the inlet of the receptacle 21.
- the opening 24 serves as the outlet of receptacle 21.
- the receptacle 21 with water treatment medium 26 contained therein serves as a water filter cartridge but its open mouth, or inlet, is covered by a screen member 27 which is screwed into the bore of the tubular portion 16 and which traps the peripheral flange 19 of the receptacle 21 on its annular seat formed by the flange 17.
- the screen member 27 has the form of an upturned cup, comprising a crown portion 28 and a depending skirt portion 29. Each of the crown and skirt portions and 28 and 29 has a series of slots 30 through it. The slots 30 are covered by mesh 31.
- a radially-outwardly projecting annular flange 32 is formed integrally with the skirt portion 29 and is spaced from the brim of the cup-shaped screen member 27 by an appropriate distance such that it is seats in a corresponding annular shoulder 33 formed at the upper end of the tubular portion 16 of the hopper 11 when that brim seats upon the peripheral flange 19 as shown in Figure 3.
- the external screw thread that engages with the spiral groove 18 is formed on the external surface of the skirt portion 29 between the annular flange 32 and brim of the cup shaped screen member 27.
- Prongs 34 depend from the structure of the screen member 27 and project into the interior of the receptacle 21 through the open mouth that forms its inlet.
- each removable cover 35, 36 has a portion by which it can be readily grasped by fingers so as to facilitate its removable when the cartridge is required for use.
- provision of the prongs 34 in the screen member 27 avoids the need to remove the cover 35 from the mouth of the receptacle 21 before installation. This is because, as is illustrated in Figure 3, the prongs 34 pierce the membrane 35 in the act of screwing the screen member 27 into position to trap the peripheral flange 19 on its annular seat.
- the membrane 36 is shown chain dotted in Figure 3 in the position in which it covers the outlet opening 24.
- cover can be used provided that when it is fitted over the inlet and/or outlet of the receptacle 21 of the cartridge, it is able to prevent moisture from escaping from the water treatment medium contained in the cartridge and that it can be selectively opened for use when required.
- the cover may be a "clip on” member.
- Such a "clip on” member could be adapted to be refitted to the cartridge after use. This is particularly advantageous when the water treatment medium is to be recycled as such refitting of the "clip on” member facilitate storage of the used water treatment medium in the cartridge until recycling thereof.
- a further advantage is that, when the cartridge is extracted with the "clip on” member refitted thereto, spillage of the water treatment is avoided.
- the means of installing a cartridge which embodies the present invention is not limited to fitting into a removable hopper of a water filter jug as described above with reference to Figures 1 to 3.
- a form of water filter jug m which the interior of the deep vessel formed by the jug is divided into two compartments by a wall extending across that interior, part way down has been proposed, and the form of installation described above with reference to Figures 1 to 3 would be for suitable use in such an arrangement because the replacement cartridge is installed from above .
- FIG. 4 illustrates such an installation
- Figure 5 illustrates a replacement cartridge for fitting therein.
- Parts of the installation shown in Figure 4 and of the cartridge shown m Figure 5 that are similar to corresponding parts of the installation described above with reference to and illustrated m Figures 1 to 3 are given the same reference characters but with suffix A.
- the peripheral flange 19A of the receptacle 21A is formed at a location in the side wall 22A that is spaced from the brim of the cup shaped receptacle 21A.
- a spiral groove 37 is formed in the outer surface of that portion of the side wall 22A that forms a neck portion 38 and that extends between the brim of the receptacle 21A and the peripheral flange 19A.
- FIG. 5 shows the receptacle 21A fitted with removable covering membranes 35A and 36A.
- the covering membranes 35A and 36A are peeled off by engagement with fingers of the portions for that purpose and the neck portion 38 is screwed into the bore of the tubular portion 16A until the peripheral flange 19A engages the lower end thereof to make a water tight seal.
- An inverted cup-shaped screen member 27A extends over the inlet of the cartridge that is formed by the open mouth at the upper end of the receptacle 21A.
- This screen member 27A is similar to that described above with reference to Figures 1 to 3 but does not include that part of the skirt portion 29 that depends below the annular flange 32.
- the annular flange 32A of the screen member 27A seats in the respective annular shoulder 33A to form a water tight seal.
- the aperture size of the meshes 25 and 31 is sufficient to allow water to flow therethrough whilst at the same time being smaller than the particles of the water treatment medium 26 so that, in use, escape of those particles from within the receptacle 21, 21A is inhibited.
- an intersticial diameter of about 50 micrometers - 300 micrometers is selected, preferably in the range of 80 micrometers - 200 micrometers.
- narrow slots could be used, the width of the slots being less than the size of the particles so that the slots inhibit passage of the particles through them.
- the receptacles are screwed into the opening formed by the tubular portion of the hopper, it should be understood that any suitable means of connecting the cartridge to the hopper could be used.
- the cartridge could be adapted to be pushed or snap fitted into engagement within the opening of the base hopper.
- unfiltered water is poured into the compartment of the hopper 11, 11A. That water flows through the mesh covered slots 30, 30A in the screen member 27, 27A and then through the water treatment medium 26, 26A in the receptacle 21, 21A.
- the receptacle 21, 21A and/or the hopper 11, 11A described above may be formed by molding.
- the meshes 25, 25A, 31, 31A may be incorporated into the receptacle 21, 21A or the screen member 27, 27A during molding thereof in accordance with the teachings of International Application No. PCT/GB97/02120.
- An advantage of using a water filter cartridge with a removable cover in accordance with this invention in a hopper fitted with an outlet member, or in a similar installation in a water filter jug, is that the cost of replacement of a water filter cartridge is reduced, as each such cartridge need only be provided with its removable seal and not additionally with a permanent closure or inlet portion.
