Cat fecal crate and procedure for shaping it

The invention relates to a fecal box for cats and the method of forming such a box.

Cats are often kept in apartments and houses without being able to go outside to see them to do normal daily business. To overcome this difficulty the owner usually uses one Box or pan with a filling like sand

409830/0696

Sawdust or a loose material specially made for
prepared for this purpose and which has a deodorant and absorbent effect _{0 is} a simple box or pan
usually unsuitable for this purpose as the cat
usually scratches and digs in the filler before and after using the box and consequently throws and
she scrapes the filler past the sides of the box onto the floor. Furthermore, when using the box, the cat will occasionally sit in such a position near the sides of the box that the debris is not drained or deposited in the filling material or not at all in the box, so that it is impossible for the cat to Covering rubbish in the normal way.

The only known conventional excrement box for
Cats, which is different from an ordinary pan, has a two-part structure that accommodates the filling material
a lid which is arranged immediately on top of the pan and which has substantially the same size and the
has grooved edges which engage a U-shaped groove made on the top edges of the sides and ends of the pan and extending completely around the periphery thereof. The outer edges of the groove in the
Pan extend slightly above the top of the side inner edges to make it easier to put the lid on the pan, and the top edge is rolled over to make a soft one

409830/0696

Provide entry surface. A fundamental problem with this conventional faeces box is that faeces that come out of the box tend to settle in the U-shaped groove for holding the lid and soiling it, so that the lid does not fit properly when it is on the pan is placed. The two-part C _o nstruktion multiplied the number of molded parts that need to be handled in lyiassenproduktionsbasis and increase costs.

There is therefore no question of a need for a one-piece To provide a fecal box for use by the cat in its normal daily needs, which it allows the Cat pits and scratches the filling material before and after using the box in the normal and customary manner, without scraping or throwing the material out of the box, the box being constructed to contain the rubbish is drained on or into the filling material and away from the sides or ends of the box and the top edges of the To provide a pan and a seal as a seat for the cover to prevent faeces from flowing out of the body to emerge.

The essence of this invention comprises a fecal box for cats, which has a deep pan entry cover with an opening in the top large enough that

409830/0696

the cat can get inside the box to help her to build v / daily business. The side walls of the Cover converge upwards to form a flat, inwardly extending flange bent around the ring, which borders the opening to a fecal area enclosed below. The side walls of the cover run down into flat sealing edges that surround the faecal area. These edges lie on the upper peripheral edges the pan on when the cover is on the box and they have a bridge extending downwards, which extends below the top of the pan. The cover forms a real protection that prevents the spillage of filling material and cat debris that normally lies on the Bottom of the box is located when the cat is in normal fashion scratches and digs in it.

The cover and pan are on the rear joints articulated to one another on a common hinge axis. Snap fasteners connect the front of the Cover and pan together along their front in the closed position. A replaceable liner for the socket, which has a circumferential overlap, which extending outwardly beyond the pan border is in position against the upper peripheral edges of the pan secured to the cover by the flat sealing edges when the cover is closed on the pan.

409830/0696

■ In a version, the joint axis lies along the cutting line of two levels formed by the top and bottom edges of the pan and the cover of the box, if this is in the partially open position. The pan and cover this waste box for cats including the joint on the binding of their backs can then be used as a A common parting plane for the mold runs along the top of the pan and across over the flat sealing surface of the cover if this is lifted from the socket and extends through the midline of the joint located in between.
