Description

The present invention relates to a litter box provided

  a sheath, and its method of production.

  Particulate materials, such as crushed clay, are currently sold as cat litter so that they form a device conveniently placed in a dwelling and intended to allow the cat to satisfy its natural instinct for depositing and burying its animals. solid and liquid feces. The litter material is normally sold in bags and is poured into a crate, bowl or other container with walls

  sides, the dimensions of the tank being sufficient

  so that the cat can stand up and scratch it

  the material without dispersing it outside the container.

  The litter boxes used by cats are often

  difficult to clean because urine often seeps through the litter material and settles

  where the litter is permanently moistened or saturated

  nence, so that the extraction of the material from the container is a tedious and unpleasant task. In addition, the litter is normally placed directly in the tray, at a place where the material and cat feces that are deposited in the litter may be in contact with the inner surface of the walls and the bottom of the tray so that these surfaces are contaminated and frequent cleaning of the bin is necessary. Given the difficulty of disposing of litter and cleaning of the cat litter container, attempts have been made to make disposable trays and have been used in a limited way, but most of them have some disadvantages, such as the lack of reliability of the container which does not retain particulate matter and urine, the instability of the container structure and in particular of its side walls, and the excessive cost of using a reliable container to be discarded every time the

  litter is thrown away. In addition, the owner of the pre-cat

  often have a more resistant and more or less permanent container that can be reused during a

  relatively long period without being replaced. We tried

  to use plastic coatings to re-

  However, until now, the known coatings have exhibited orientation defects, positioning defects and / or tears caused by the cat, given its normal scratching habit, if Although the waste and other dirt could come directly into contact with the surfaces of the crate, the unpleasant task of removing the litter and cleaning the bin was necessary. The present invention essentially relates to a cat litter sleeve which fits over the tray and around its inner part and which conveniently plays the role of a

  The invention also relates to the production of a furnace

  by upright lifting and disposal of the litter so

  that it can be transported and evacuated.

  The invention also relates to a litter box provided

  a sheath, intended for cats and in which the oven

  The tub completely surrounds the tub and bears against and along the inner sidewalls so that the probability of tearing and tearing by the cat is reduced to a minimum, the tubing being

  More specifically, according to the invention, a sheath made of a sheet of plastic or a similar material, having substantially the shape of a bag, is used and is preferably slid on the body, from one end to the other, a side of the sleeve being pushed by the open upper side of the cat tray and bearing against the inner walls and the bottom of the tray. This preferably has a relatively rigid structure, able to support the litter and the cat without significant deformation or sagging of the sides or the bottom, the tray being normally formed of plastic or thick cardboard. When the bag-shaped sheath has been slid horizontally on the tray and when the upper face substantially covers the internal space of the tray, the open end portion of the sheath is preferably formed by folding

  and gluing the end under the tray. The part of

  turn of the outer surfaces and on the upper edges of the tray. This arrangement provides a clean appearance and minimizes the risk of scratching or tearing of the sheath by the cat when it enters the litter and comes out or when burrowing in the litter during use of the tray. The sheath is normally made of a sheet of

  relatively thick plastic material, preferably im-

  impregnated with a deodorant product or coated with one or more odor suppressor or masking agents, and it gives effective protection of the tray against the feces of

  cats and at the same time it gives a clean appearance and preferably

  smell pleasant to the whole.

  When the litter in the tray must be changed, the open end of the sleeve is disengaged and the portion of the bag forming the opening is folded on itself and is pulled towards the other end of the tray. During this operation, the sheath surrounds the soiled litter and takes

  the shape of a bag, the litter being contained in the oven

  even. The sheath, which is then in the form of a conventional bag and which contains the used litter, can be used for transporting the litter to an evacuation location, usually a garbage bin, a removal site or a landfill. A new sheath is then placed on the tray as previously described, and a new amount of litter is placed on the sheath disposed on the opening of the litter box so that the tray is filled and used again by the cat. In one variant, several

  to change the sheath and prevent the contact of the

  litter with the bin in case of tearing of the sheath.

  Referring now to the drawings and in particular to Figure 1 in which the reference 10 designates a litter box and reference 12 a sleeve for the tray before mounting the sleeve on the tray. The litter box has four side walls 14, 16, 18 and 20 connected to each other.

  other and to a bottom 22. The upper edge of the side walls

  preferably has a rounding 24 or other configuration.

  forming a regular upper edge of the tray. This is preferably formed of plastic, forming a

virtually rigid structure.

  The sheath 12 normally comprises two layers 30 and 32 connected to each other at their edges 34, 36 and 38, the edges 40 of the end portion 42 not being connected to the respective edges of the sheet facing each other. so that an opening is formed in the sheath. The three edges 34, 36 and 38 may be connected by heat sealing or any other method of connection so that a continuous structure is formed between the two sheets along these three edges. In a variant, the two sheets can be made in one piece and the edges of the sheets

  can be connected to end 38 so that a structure

  The entire bag is made, the access being obtained by the opening 44 delimited between the sheets at the edges 40, because these two edges are not connected to one another. The sheet material from which the sheath is formed is

  a relatively thick and tenacious plastic material,

  able to support scratching by a cat when using

  sation of the litter in the assembly formed by the tray and the sheath. The latter, comprising two layers 30 and 32, preferably has a dimension such that it fits intimately on the tray after the upper face has been pushed into the tray along the side walls and the bottom; however, some additional space is desirable so that bins of different sizes and possibly of different shapes can be accommodated. The sheet material is preferably impregnated with a material for removing or obscuring odors or a material having a

  perfume, giving a pleasant smell in the tray and the li-

  and all around after the sheath has been mounted on the tray and that the litter has been placed in it. The bag may be impregnated with deodorants by mixing the agents with the plastic prior to manufacture or at the time of manufacture of the sheath material, or the deodorant may be applied to the outer surface

  the sheath after the formation of it. The deodorant agent

  may have various compositions giving the odor or

  desired deodorant effect according to the particular criteria.

  When the sheath is to be mounted on the tray, it is put in the position shown in Figure 1 and is

  open at the end portion 42 in a manner sufficient to

  the tray can be slid into the envelope-shaped sheath or so that the envelope can be slid on the tray as shown in Figure 2. The sheath and the tray are moved one

  towards the other until the sheath completely covers

  the tray, the end portion 42 protruding from the tray. The upper layer or sheet 30, as shown in the figure, is disposed on the upper opening of the tray and is pushed down into the tray so that the sleeve, when fully placed in position on the tray, no only covers the inner surface of the four walls and the bottom but is also drawn in close cooperation with the

  corresponding external surfaces of the walls.

  When the sheath is mounted as described so far, the litter 46 is poured, normally from a bag as indicated by reference 48, to the upper face of the sheet 30, the weight of the litter pushing back the sheet in intimate contact with the surface

  internal of the four walls and the bottom. A sufficient amount

  litter 46 is added to the assembly formed by the tray and the sheath so that a suitable bed of litter is formed and allows the cat to behave according to its

  daily habits, satisfying his natural instinct

  rel deposition and burial of his solid excrement

  and liquids. When the bedding material was

  added to the set formed by the tray and the oven

  water as shown in Figure 3, the open end of the sleeve is normally glued under the assembly 50,

  between the sheath and the ground. The sheath, in this position

  tion, forms a hygienic coating for the tray and gives

a nice appearance to the whole.

  When the litter has been used and needs to be changed, the open end of the sheath is removed from below the set formed by the tray and the sheath and is open, and the edges of the sheet material forming the opening are folded peripherally onto themselves and

  the sheath is removed on the tray and the material of li-

  as shown in Figure 5. When the furnace

  the water is pulled to the left, it turns around and simultaneously surrounds and holds the litter when the removed bag is formed in this operation as shown in Figures 5 and 6. The sheath is pulled until it it is completely removed from the tray and contains all the litter material and, when the operation has been performed, the sheath has the shape of a bag containing the litter and it keeps this form while the litter and the bag are evacuated in any suitable manner, for example in a garbage bin, by garbage removal or in a landfill. Thanks to the structure and operation indicated above, the cat tray can be processed without

  contact with the bedding used and the bin may be

  kept in a hygienic state. A new sleeve can then be mounted on the tray in the manner indicated above,

  without washing or cleaning the bin.

  The embodiment shown in FIG. 7 is substantially the same as that of the preceding figures, the only difference being that, after mounting the sleeve as shown in FIG. 2, the open end 42 is connected or closed by a device 52 and the end can remain free instead of being glued under the tray although, if necessary, the end can be glued under the tray as shown in Figure 7. It is usually desirable that the litter is placed on the sheath placed in the tray before knotting

  end 42, because fixation may prevent

  sheath in intimate contact with the walls

  dull and the bottom of the tank. When the sheath is to be removed, the fastener must be removed from the end portion before the sheath

  can be removed as previously described.

  In the embodiment of FIGS. 8 to 10, several sleeves 12, 112, 212 and 312 are placed on each other as shown, the inner sleeve 312 is placed in the manner described above, the litter material being initially poured onto the external sleeve 12. When a change is necessary, only the outer sleeve is removed, by the operation described above, so that the next sleeve, the sleeve 112 in the case in question, appears. The operation is repeated until

  the use of all sleeves 12 to 312.
