DETAILED DESCRIPTION

[0056] FIG. 1 is a schematic perspective view of a waste receptacle 1. The waste receptacle comprises a housing that is (in this implementation) generally cuboid in form and includes a door panel 3 in which an access port 5 has been provided, so that an animal such as a cat can access an interior void 7 of the waste receptacle.

[0057] As shown in FIG. 2, the door panel 3 can be opened to enable a user to access the void defined by the receptacle 1. A liner 9 fits within the void 7, and can be accessed by an animal via the access port. In use, the liner 9 defines a liner void that will typically contain a measure of litter material. As will later be described in detail, in this particular implementation the liner is self-supporting and comprises a resiliently deformable member that can be deformed to enable the liner to be inserted into and removed from the void. Once the liner has been inserted, the resiliently deformable member returns to its' original shape to hold the liner by means of friction against the internal walls of the receptacle. One such illustrative deformable member comprises a length of spring steel formed into a hoop and located inside an upper peripheral portion (as orientated in use) of the liner.

[0058] FIG. 3 is a perspective view of another waste receptacle 4. This receptacle 4 differs from that of FIGS. 1 and 2 in that the access port 5 is provided in a removable platform 11 that forms a top cover of the receptacle in use. The receptacle 44 of FIG. 2 is a top-entry waste receptacle, whereas the receptacle of FIGS. 1 and 2 is a front- or side-entry waste receptacle.

[0059] The platform 11 comprises a major portion 13 and a minor portion 15 that are, in this arrangement, hingedly coupled to one another so that the major portion can be pivoted—relative to the minor portion—between a closed position depicted in FIG. 3 where a pet owner's access to the liner 9 (other than via the access port 5) is obstructed and an open position depicted in FIG. 4 where access can be had to the liner 9.

[0060] In the particular example depicted in FIGS. 3 and 4, the liner 9 includes a resiliently deformable band inside an upper peripheral portion of the liner. The band is sized so that it bears, in its non-deformed state, against internal walls of the receptacle to keep the peripheral walls of the liner from collapsing.

[0061] FIG. 5 is an illustrative perspective view of another waste receptacle 17. This receptacle 17 includes a platform 11 which is enclosed within the interior void defined by the receptacle 17. The receptacle, in this instance, comprises a door panel 3 in which an access port 5 has been provided. The platform 11 includes a platform access port (not visible) so that an animal entering the receptacle can access a liner (also not visible) provided beneath the platform. The platform 11 could be of the type shown in FIGS. 3 and 4, or could simply comprise a planar body with a platform port provided in it. Access to the liner and platform by an owner is enabled by means of the aforementioned door panel 3, which can be opened.

[0062] FIG. 6 is a schematic view of an illustrative liner 9, and FIG. 7 is a schematic cross-sectional view along the line A-A of FIG. 7. The liner may be manufactured of a variety of different materials, for example of a textile material, a plastics material or a textile/plastics mix, and is preferably waterproofed (either inherently or by application of a waterproof layer or component)). The liner comprises a base 19 (not visible in FIG. 6) and one or more sidewalls 21 that cooperate with the base 19 to form a receptacle for a measure of litter tray material (such as “AmazonBasics Cat Litter Wood Pellets” available from http://www.Amazon.co.uk., or similar). The liner is open at an end remote from the base 19 (which end will be uppermost in use) so that an animal, for example a cat, can enter inside the liner to urinate or void its' bowels.

[0063] As shown in FIG. 7, a peripheral portion 23 of the liner sidewall 21 is folded over to provide a void within which a resiliently deformable retainer 25 is provided. The retainer 25, in this particular embodiment, comprises a hoop of resiliently deformable material (such a sprung steel, for example) that can be deformed to allow the liner to be fitted into a receptacle, whereupon the retainer returns to its non-deformed shape and bears upon internal walls of the receptacle to hold the liner in place in use.

[0064] In the preferred embodiment it is envisaged that the retainer comprises a hoop. It will be apparent, however, that the retainer need not necessarily comprise a hoop. For example, a generally C-shaped length of resiliently deformable material may suffice to hold the liner in place in use. Other equivalent arrangements will be apparent to persons of skill in the art.

[0065] Referring now to FIG. 8 of the drawings, the line 9 further comprises a pocket 27 provided on an external face of the sidewall 21 so that the pocket will lie between the liner sidewall 21 and an internal face of the receptacle when the liner is located in the receptacle. The pocket 27 is sized to accommodate a scoop 29 for removing pet waste and/or soiled litter from the liner.

[0066] As shown in FIG. 9, when the liner 9 is installed in a receptacle 3, the aforementioned pocket 27, and any scoop 29 provided therein, is normally obscured from view and access thereto is obstructed by the liner. By pulling a peripheral edge portion 31 of the liner 9 (which edge portion is in the vicinity of the pocket 27) away from the receptacle the pocket is revealed and access can be had thereto. An advantage of this arrangement is that when the liner is provided within the receptacle with the retainer abutting against the internal walls, the pocket and scoop is obscured from view and access thereto is restricted. This means that users no longer need have soiled scoops on view and easily accessible.

[0067] FIGS. 10 and 11 show another form of liner where the peripheral edge portion 31 in the vicinity of the pocket is provided with a tab 33 that makes it easier for the user to pull the liner sidewall away from the receptacle. In another envisaged implementation, the tab may be configured to couple to the receptacle sidewall to secure the liner in position in use. To enable this, the tab may carry one part of a two-part engagement mechanism, the other part being carried by the receptacle sidewall. Velcro™ or a press-stud (otherwise known as a snap fastener) could be utilised to secure the liner to the receptacle. Alternatively, the tab could be configured as a hook that hooks over the top of the receptacle sidewall to support the liner in use. FIG. 12 is an illustrative representation of the receptacle of FIGS. 1 and 2 showing a pocket 27 provided in a sidewall of the liner 9.

[0068] As aforementioned, utilising a retainer 25 to secure a liner 9 against the sidewalls of a receptacle, as shown in FIG. 13, is merely one illustrative way of securing the liner 9 in place in use. In another illustrative implementation shown schematically in FIG. 14, the liner 9 may be configured to couple with retaining clips 35. In this particular example, the clips 35 are configured to hook over the peripheral wall of the receptacle 3. In other arrangement the clips may be configured to engage with the receptacle wall (for example by means of a suitable coupling) or may be permanently attached thereto. The clips 35, in this particular arrangement, include a peg 37 that can be mated with a complementary eyelet 39 in the liner to secure the liner to the peripheral wall of the receptacle. As will be appreciated, other two-part complementary attachment mechanisms may be employed instead of, or as well as, a peg and eyelet.

[0069] Referring now to FIGS. 15 and 16, there is depicted a schematic representation of a platform and liner support 41. The support 41 is configured for attachment (for example by means of an adhesive or fixings such as screws) to an internal surface of the receptacle sidewalls. In one arrangement, the receptacle is generally rectangular in plan view and a support 41 is affixed to each of the longer sidewalls. In another implementation a support may also or alternatively be affixed to the shorter sidewalls. In addition, whilst it is preferred for the support to extend along substantially the entire length of the sidewalls, this may not be necessary, and the support may instead extend only over a part of the length of the sidewall.

[0070] Referring now to FIG. 16, the support 41 comprises a ledge 43 that functions as a support for the platform 11. As shown the ledge 43 extends inwardly into the receptacle when the support is affixed to the internal walls thereof. A first wall 45 extends generally perpendicularly from an edge of the ledge 43 that is proximate the sidewall of the receptacle when the support is installed, and a second wall 47 extends generally perpendicularly from an edge of the first wall 45 distal of said ledge 43. The ledge and first and second walls cooperate to form a cavity into which the resiliently deformable retainer 25 of a liner 9 can be fitted so that the liner is supported, in use, with its sidewall upstanding by the support 41. This arrangement makes it less likely for the liner sidewall to collapse during use.

[0071] FIGS. 19 and 20 illustrate, and reinforce, the fact—described above—that it is not essential for the platform and liner support 41 to extend along the entirety of a wall of the receptacle. In the particular example illustrated, the receptacle is generally rectangular in plan view and is provided with supports 41 that extend along the entire length of each shorter wall, and partway along the length of each longer wall.

[0072] Referring now to FIGS. 17 and 18, the receptacle may further comprise a platform retainer 49 that cooperates with a complementary formation 51 in—in this particular case—the minor portion 15 of the platform 11, to help retain the platform 11 in place. The complementary formation 51 comprises a generally rectangular recess and the platform retainer comprises a generally rectangular body that can fit within the recess. In the preferred arrangement a recess is provided on either peripheral edge of the minor portion 15 of the platform 11 for cooperation with complementary formations on either side of the receptacle.

[0073] As depicted in FIG. 18, the minor portion 15 of the platform can be slid along the ledge 43 of the platform and liner support 41 until the platform retainer 49 affixed to the sidewall of the receptacle locates in the complementary formation 51 provided in the minor portion 15 of the platform 11. Once so located, the platform is less likely to be dislodged, for example by means of a cat stepping onto it.

[0074] Referring now to FIGS. 21 and 22, there is depicted a scoop 29 that is particularly well suited for use with the liner described herein. FIG. 21 is a plan view of the scoop in which the scoop is substantially planar (and hence can easily be slid into a pocket provided on the outside of a liner). FIG. 22 is a perspective view of the scoop of FIG. 21 after it has been manipulated to form a three dimensional body.

[0075] The scoop comprises a base portion 53 that is, in the preferred arrangement, perforated so that unsoiled litter can fall through the base and back into the liner. Peripheral lateral edges of the base 53 are coupled to respective first and second side panels 57, 59, in this instance by means of living hinges 61.

[0076] First and second handle portions 63, 65 are coupled together, in this instance by a living hinge 67. A first end 69 of the first handle portion 63 is coupled via a living hinge 71 to a first end wall 73 that is coupled by another living hinge 75 to the first side panel 57. Similarly a first end 77 of the second handle portion 65 is coupled via a living hinge 79 to a second end wall 81 that is coupled by another living hinge 83 to the second side panel 59.

[0077] As will be appreciated, bringing the two handle portions 63, 65 together causes the sidewalls 57, 59 to move relative to the base portion 53 towards one another and the two end walls 73, 81 to come together; thereby forming a three-dimensional scoop as shown in FIG. 22.

[0078] Referring now to FIG. 23, a problem with existing liners 100 is that when the liner is lifted out of the receptacle, the base of the liner tends to sag. As a result, unused litter, soiled litter and animal excreta tend to pool in the bottom of the liner, making it difficult for the user to remove excreta and soiled litter with a scoop. It is also the case that the base of the liner can be prone to rucking by the animal in use.

[0079] To address this issue, as shown in FIGS. 24 to 26, it is proposed to provide a liner 102 that includes a housing 104 for a base reinforcing member 112. In this particular example, the housing 104 comprises a base pocket 106 formed by coupling an additional base panel 108 to a primary base portion 110 of the liner 102. As shown in FIG. 24 a reinforcing member 112 can be inserted into the base pocket to reduce the likelihood of the base sagging when the liner is removed from a receptacle. Since the reinforcing member can be removed from the base pocket, users are still able to turn the liner inside-out whilst cleaning it. Another advantage of this arrangement is that the reinforcing member helps to reduce the likelihood of the base 110 rucking whilst the receptacle is being used by an animal.

[0080] In this example the pocket is closed at one end, but it will be appreciated that the pocket could be more akin to a sleeve and open at both ends. Similarly, whilst a tray-like configuration for the reinforcing member is envisaged, the reinforcing member could have a variety of different configurations. The liner 102 may include a pocket for a scoop as in other embodiments described herein, and may—as shown in FIG. 26—include a resiliently deformable retainer of the type that is elsewhere described herein. Alternatively, the liner may be configured to couple to clips, for example as with the liner depicted in FIG. 14.

[0081] Another embodiment of a liner 114 is depicted schematically in FIGS. 27 to 29 of the accompanying drawings. This liner 114 is particularly, but not exclusively, intended for use with waste receptacles 1 of the type shown in FIGS. 1 and 2. As shown in FIGS. 1 and 2, the liner 9 described above has a front wall 10 (as orientated in use) that is lower than a rear wall (not visible) of the liner so that an animal can clamber into the liner via the port 5 in the door 3. Whilst this arrangement functions adequately, the front wall of the liner can sometimes be caught by the animal as it clambers into the waste receptacle and pulled away from the depicted upright position. This raises the possibility of litter falling in between the liner and the door to the receptacle.

[0082] The liner 114 depicted in FIGS. 27 to 29 includes a front wall 116 (as orientated in use) that is substantially the same height as a rear wall 120 and interconnecting sidewalls 122. The front wall 116 includes an access port 124 that aligns with the access port 5 in the door 3 when the liner 114 is installed in a waste receptacle 1.

[0083] The front wall 116 is comprised of an inner wall 126 that extends between respective interconnecting walls 122, and an outer wall 128 that is coupled to the inner wall around the periphery of the access port 124, towards the peripheral edge portion 31, and to the remainder of the liner at opposite lateral peripheries. The inner and outer walls 126, 128 co-operate to provide a housing for a front wall reinforcing member 130. In this particular example, the housing comprises a pocket 131 that opens towards a base wall 134 of the liner 114.

[0084] The reinforcing member 130, in this embodiment, comprises a generally U-shaped outer frame 132 comprised of a head portion 134 and two leg portions 136 extending from respective ends of the head portion 134. A cross-brace 134 extends between the legs 136 of the U-shaped outer frame 132 and is generally parallel to the head portion 134. The cross-brace 134 is spaced from the head portion 134 of the U-shaped outer frame by a distance that is similar to the distance between the base 136 of the liner 114 and a lowermost (as orientated in use) portion of the access port 124.

[0085] When the U-shaped frame is inserted into the pocket 132, the legs of the U-shaped frame 132 extend from a point roughly adjacent the base of the liner 114 along respective lateral edges of the outer wall 128 and help to ensure that the front wall remains generally upright in use. The cross-brace will lie in the vicinity of the lowermost (as orientated in use) portion of the access port 123 and support the access port 124.

[0086] In one envisaged arrangement the liner may include only the aforementioned housing for a front wall reinforcing member 130. In another envisaged implementation, the liner may, as shown in FIGS. 27 to 29, include both a housing for a front wall reinforcing member and a housing for a base reinforcing member 112 of the type shown in FIGS. 24 to 26. In this latter case, the U-shaped frame 132 and the base reinforcing member 112 may be configured so that the U-shaped frame 132 can be positively engaged with the base reinforcing member 112, for example snap-fitted into the base reinforcing member 112 so that the two components are coupled together. This arrangement provides additional support for the walls of the liner.

[0087] As shown in FIG. 28, the liner may also be provided with a pocket 27 for receiving a scoop, for example a pocket of the type described above in connection with FIGS. 8 to 10 of the drawings.

[0088] It will be appreciated that whilst various aspects and embodiments of the present invention have heretofore been described, the scope of the present invention is not limited to the particular arrangements set out herein and instead extends to encompass all arrangements, and modifications and alterations thereto, which fall within the scope of the appended claims For example, the platform and liner support need not necessarily be configured for use with a liner that includes a resiliently deformable member. It could, for example, comprise a plurality of hooks that are o-operable with eyes provided in the liner sidewall to support the liner.

[0089] It should also be noted that whilst the accompanying claims set out particular combinations of features described herein, the scope of the present invention is not limited to the particular combinations hereafter claimed, but instead extends to encompass any combination of features herein disclosed.

[0090] Finally, it should be noted that any element in a claim that does not explicitly state “means for” performing a specified function, or “steps for” performing a specific function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. Sec. 112, par. 6.
