Kitty litter box The invention relates to a kitty litter box, comprising an assembly of a housing and a lining co-operating with the housing, wherein the housing is formed as a first box comprising a bottom and upright side walls, and is designed for permanent use, and in that the lining is removable and that it is formed as a disposable second box of a size such that the second box can be accommodated in the first box substantially without play between the first and the second box.
Such a litter box is known from WO 96/36217. Both the housing and the lining for the housing of this known kitty litter box are rectangular in shape. The disposable second box comes as a bottom plate with substantially upright intermediate portions adjacent to the bottom plate and side walls that are movably coupled to the intermediate portions, whereby two opposite side walls can be moved toward the bottom plate between the upright intermediate portions, and the other two side walls can be placed upon the upright intermediate portions as lid, albeit that the lid does not seal this half-product entirely.
Also from US-A-4,348,982 a kitty litter box according to the preamble of the main claim is known. Both the housing and the disposable box to be placed inside the housing according to this citation are as well rectangular in shape.
Furthermore, from US-A-4,788,935 a cat litter box is known which is formed as a completely disposable assembly of a housing and contents for the housing. The contents of the housing comprise a half-product serving as packaging, which by unfolding becomes a box comprising a bottom plate and upright side walls. In one of the side walls an opening is provided for the cat. After the box has been folded out, a sleeve supplied therewith can be used to complete the cat litter box. The sleeve then AMENDED SHEET
04-',2-2000 functions as housing. After the cat litter box has been used, the box enveloped by the sleeve is returned to its original half-product condition, for which purpose the side walls are pushed from outside the sleeve, into the folded condition.
The cat litter box according to US-A-4,788,935 has several drawbacks. Firstly, manipulating the box in order to insert it into the sleeve when using the cat litter box for the first time as well as pushing back the walls of the box through the sleeve after it has been used, is rather akward. Secondly, there is a large amount of waste, since every time the box containing the excrements of the cat is discarded, the sleeve thus serving as waste disposal bag, also has to be discarded.
Thirdly, the assembled known cat litter box consisting of a cardboard box and an enveloping flexible sleeve, does not stand very firmly when in use so that it can easily become a play ball for the cat. This has negative consequences with respect to the hygiene of the cat litter box.
The object of the invention is to improve the ease of handling and the sanitary features of the cat litter box according to WO 96/36217, and to arrive at further advantages that will be explained below. To this end, the cat litter box according to the invention is characterized in that the housing is open at its tap and optionally includes a lid, and that the side walls of the second box are slightly tapered from the bottom upward.
This facilitates easy placing and simple removal of the second box from the housing of the cat litter box.
Desirably also, the second box is formed from a sheet of plastic or cardboard comprising a bottom plate coupled to which are the side walls. This makes it possible on the one hand to manufacture the second box conveniently and at low cost from, for example, recyclable or recycled cardboard, and on the other hand it makes it possible to bring the second box on the market in a manageable size. This latter aspect will be explained below.
AMENDED SHEET
r , A preferred embodiment is characterized in that each of the side walls of the second box is firmly connected with its bottom plate via an intermediate portion and in that each of the intermediate portions extends substantially perpendicularly in relation to the bottom plate and is firmly connected with its adjacent intermediate portions. The upright intermediate portions together with the bottom plate form a receptacle for moisture that collects in the second box, without being able to seep through.
It is further preferred that there are four side walls, of which two opposite side walls are substantially in straight alignment with first fold lines surrounding the bottom plate, and of which the other two side walls are somewhat wider in relation to the first fold line surrounding the bottom plate, and that at some distance from their side edges the said wider side walls have a second fold line, providing the wider side walls with flaps that can be directed toward the straight side walls.
This embodiment makes it possible to form the box, when the same is unfolded such as to taper from the bottom plate upward, in conformity with the housing.
The simple placing of the second box then allows the flaps to fulfil the function of seal between the adjacent side walls, which seal comes into action because due to the tapering of the housing said side walls and flaps are pushed toward each other.
Advantageously the flaps are provided with lips that can project outward to clampingly couple the wider side walls to the straight side walls. To further promote a close fit between the side walls, the straight side walls are provided with notches in their side edges suitable for receiving the lips. To ensure that the transition between the adjacent side walls is sealed properly, it is favourable to have the lips substantially extending diagonally in the flaps. This makes the tapering shape of the second box more stable.

AMENDED SHEET
r , A preferred embodiment is characterized in that each of the side walls of the second box is firmly connected with its bottom plate via an intermediate portion and in that each of the intermediate portions extends substantially perpendicularly in relation to the bottom plate and is firmly connected with its adjacent intermediate portions. The upright intermediate portions together with the bottom plate form a receptacle for moisture that collects in the second box, without being able to seep through.
It is further preferred that there are four side walls, of which two opposite side walls are substantially in straight alignment with first fold lines surrounding the bottom plate, and of which the other two side walls are somewhat wider in relation to the first fold line surrounding the bottom plate, and that at some distance from their side edges the said wider side walls have a second fold line, providing the wider side walls with flaps that can be directed toward the straight side walls.
This embodiment makes it possible to form the box, when the same is unfolded such as to taper from the bottom plate upward, in conformity with the housing.
The simple placing of the second box then allows the flaps to fulfil the function of seal between the adjacent side walls, which seal comes into action because due to the tapering of the housing said side walls and flaps are pushed toward each other.
Advantageously the flaps are provided with lips that can project outward to clampingly couple the wider side walls to the straight side walls. To further promote a close fit between the side walls, the straight side walls are provided with notches in their side edges suitable for receiving the lips. To ensure that the transition between the adjacent side walls is sealed properly, it is favourable to have the lips substantially extending diagonally in the flaps. This makes the tapering shape of the second box more stable.
A further desirable preferred embodiment is characterized in that the straight side walls are coupled AMENDED SHEET
with the long sides of the bottom plate and that approximately halfway up, they are provided with a third fold line extending parallel to said long sides; it being further desirable that the straight side walls near the edge furthest away from the bottom plate, are provided with a cut-out in the shape of the handgrip. Amongst others this makes the second box in the cat litter box according to the invention much more manageable both before and after it has been used.
It is further desirable that the interior of the second box be provided with a moisture-proof lining. This particularly serves the hygiene of the cat litter box according to the invention, since all the cat's moist excrements can be safely collected in the second box. In addition it is desirable that said second box be provided with cat-box litter such as granules or the like.
The invention is also embodied in a sheet, suitable for forming a box as described above, and in a half-product formed from such a sheet, which half-product is also suitable for forming such a box that serves as part of the cat litter box according to the invention.
The sheet of the invention comprises a substantially rectangular bottom plate as well as intermediate portions which are adjacent to the bottom plate and separated from the bottom plate by first fold lines and side walls which are adjacent to the intermediate portions and separated by fourth fold lines, two opposite side walls extending in straight alignment with the first fold lines, and the other two side walls being wider in relation to the first fold lines.
The invention is also embodied in a further development of the half-product known from WO 96/36217.
According to the invention, the known half-product comprising a bottom plate and adjacent to the bottom plate substantially upright intermediate portions, and side walls movably coupled to the intermediate portions, of which two opposite side walls can be moved toward the bottom plate between the upright intermediate portions, and the other two side walls can be placed upon the AMENDED SHEET
upright intermediate portions as lid, is characterized in that approximately at the halfway point, the side walls usable as lid are provided with third folding lines extending parallel to the bottom plate, and in that the 5 portions of said side walls bordering to the third fold line and facing away from the bottom plate abut and extend parallel to the bottom plate.
The advantage of this half-product forming the basis for a finished second box for placing into the housing of the cat litter box is that after its use, it provides a sealed wrapping for the fowled contents of the second box by folding the same after removal from the housing to obtain the original half-product. Desirably, the adjacent portions of the side walls are provided with a cut-out near the edge that is farthest removed from the third fold lines.
This provides a hand grip to facilitate easy handling of the half-product.
The invention is further embodied in an assembly of two such half-products, which assembly is formed by abutting two such half-products in mirror image. Such an assembly provides two half-products which, from a consumer s point of view may be conveniently applied in a standard shopping pattern, which is characterized in that the shopping is done once a week. In such a pattern, two half-products will meet the weekly requirement of two boxes to be used in the housing of the cat litter box.

1 the cat litter box is shown without a second box inserted therein, but with the lid 2, lifted of the housing 1. In the right-hand part of Fig. 1 is shown that a finished second box 3, made from a sheet or half-product 5 is inserted in the housing 1. One of the side walls 11 of the second box 3 is provided with an opening 5 which corresponds to the opening 4 provided in the housing 1. As can be clearly seen in Fig. 1, the housing 1 is formed like a box with a bottom and upright side walls and is 10 also provided with a lid 2. This housing 1 with lid 2 is designed for permanent use. The second box 3 is made to be removable from the housing 1 and is formed as a box of a size such that it can be inserted into the housing 1, avoiding any play between the housing 1 (the first box) 15 and the second box 3. Fig. 1 also clearly shows that the side walls 8,11 of the second box 3 taper slightly from the bottom plate upward, to correspond with the side walls of the housing 1.
With reference to Fig. 2 it is noted that the 20 second box 3 is formed from a sheet shown in this figure and made, for example, of plastic or cardboard, comprising the bottom plate 6 and side walls 8,11 coupled to the bottom plate 6. Each of the side walls 8,11 of the second box 3 is connected with the bottom plate 6 via an 25 intermediate portion 7. When the sheet has been brought into the form of the half-product or into the form of the finished box 3, each of the intermediate portions 7 stand substantially perpendicular in relation to the bottom plate 6, and all intermediate portions 7 are firmly inter-30 connected.
Fig. 2 further clearly shows that there are four side walls 8,11, of which two side walls 8 are positioned opposite each other and which are substantially in straight alignment with first fold line 14 surrounding the 35 bottom plate 6. In relation to the first fold lines 14 the surrounding the bottom plate 6, the other two side walls 11 are slightly wider, and at some distance from the side rims of said wider side walls 11, a second fold line 16 is provided in order to provide flaps 12 that can be directed toward the straight side walls 8. Said flaps 12 are further provided with outward projectable lips 13 for clampingly coupling the wider side walls 11 to the straight side walls 8.
5 Fig. 2 further clearly shows that the edges of the straight side walls 8 have been provided with a notch 17, suitable to accommodate the lips 13, and that the lips 13 extend in the flaps 12 substantially diagonally.
Especially this latter measure contributes to the desired 10 tapering shape of the second box, when it is finished just before insertion into the housing 1.
In the preferred embodiment shown in Fig. 2, the straight side walls 8 are coupled with the long sides of the bottom plate 6 and are provided approximately half-way 15 up with a third fold line 18 extending parallel to said long side.
At the side facing away from bottom plate 6, the straight side walls 8 are provided with cut-outs 19 shaped as handgrip 19. The function of the handgrip is 20 particularly clearly shown in Fig. 3, representing the assembly of two half-products formed from the sheet according to Fig 2. The half-product formed from the sheet according to Fig. 2 is not further shown in the figures since for a person skilled in the art that shape is 25 sufficiently clearly shown in Fig. 3. The half-product can be formed from the sheet according to Fig. 2 by bending the intermediate portions 7 more or less perpendicularly two the bottom 6 along the first fold line 14 and by bonding these by means of adhesive or the like. The side 30 walls 8,11 are coupled to these intermediate portions 7, which together with the bottom plate 6, form a shallow tray. The wider side walls 11 are then bent toward the inside of the shallow tray after the flaps 12 have first been bent inward along the second fold lines 16. The side 35 walls 11 then fit into the shallow tray formed by the bottom plate 6 and the upright portions 7. Said shallow tray can then the closed off by means of the side walls 8, by folding them toward each other until they practically abut to the third fold lines 18. The portions 10 of the side walls 8 fartherst removed from the bottom plate 6 then abut and can then together be folded toward one and the same side parallel to the bottom plate 6, as is clearly shown in Fig. 3.

Various modifications to the exemplary embodiment discussed are possible, all within the scope of the appended claims.
With reference to Fig. 2 it is noted that the 20 second box 3 is formed from a sheet shown in this figure and made, for example, of plastic or cardboard, comprising the bottom plate 6 and side walls 8,11 coupled to the bottom plate 6. Each of the side walls 8,11 of the second box 3 is connected with the bottom plate 6 via an 25 intermediate portion 7. When the sheet has been brought into the form of the half-product or into the form of the finished box 3, each of the intermediate portions 7 stand substantially perpendicular in relation to the bottom plate 6, and all intermediate portions 7 are firmly inter-30 connected.
Fig. 2 further clearly shows that there are four side walls 8,11, of which two side walls 8 are positioned opposite each other and which are substantially in straight alignment with first fold line 14 surrounding the 35 bottom plate 6. In relation to the first fold lines 14 the surrounding the bottom plate 6, the other two side walls 11 are slightly wider, and at some distance from the side rims of said wider side walls 11, a second fold line 16 is provided in order to provide flaps 12 that can be directed toward the straight side walls 8. Said flaps 12 are further provided with outward projectable lips 13 for clampingly coupling the wider side walls 11 to the straight side walls 8.
5 Fig. 2 further clearly shows that the edges of the straight side walls 8 have been provided with a notch 17, suitable to accommodate the lips 13, and that the lips 13 extend in the flaps 12 substantially diagonally.
Especially this latter measure contributes to the desired 10 tapering shape of the second box, when it is finished just before insertion into the housing 1.
In the preferred embodiment shown in Fig. 2, the straight side walls 8 are coupled with the long sides of the bottom plate 6 and are provided approximately half-way 15 up with a third fold line 18 extending parallel to said long side.
At the side facing away from bottom plate 6, the straight side walls 8 are provided with cut-outs 19 shaped as handgrip 19. The function of the handgrip is 20 particularly clearly shown in Fig. 3, representing the assembly of two half-products formed from the sheet according to Fig 2. The half-product formed from the sheet according to Fig. 2 is not further shown in the figures since for a person skilled in the art that shape is 25 sufficiently clearly shown in Fig. 3. The half-product can be formed from the sheet according to Fig. 2 by bending the intermediate portions 7 more or less perpendicularly two the bottom 6 along the first fold line 14 and by bonding these by means of adhesive or the like. The side 30 walls 8,11 are coupled to these intermediate portions 7, which together with the bottom plate 6, form a shallow tray. The wider side walls 11 are then bent toward the inside of the shallow tray after the flaps 12 have first been bent inward along the second fold lines 16. The side 35 walls 11 then fit into the shallow tray formed by the bottom plate 6 and the upright portions 7. Said shallow tray can then the closed off by means of the side walls 8, by folding them toward each other until they practically abut to the third fold lines 18.
