Description

Cat toilet, especially a foil pack that can be used for this purpose, and processes for their manufacture

The invention relates to a cat toilet, with a lower part in the form of an open-topped bowl, an interchangeable bag filled with cat litter, which can be inserted into the lower part, the closing area of which, after being inserted into the lower part, opens the bag over the upper peripheral edge of the lower part can be pulled out and after the cat litter has ended, for at least partially temporarily closing the cat litter

Pouch is collapsible, and an upper part removably attachable to the lower part after pulling out the sealing area of the bag for covering the upper edge area of the lower part and securing the protruding sealing area of the bag on the upper peripheral edge of the lower part, a foil pack with a bag for holding pourable material , such as cat litter or the like, in particular for use in such a cat toilet, and a method for producing such a foil pack.

As is well known, cats are easily accustomed to putting urine and faeces in a special container. Such containers, known as cat toilets, which used to be filled with sand in the past, are now increasingly covered with a special porous, absorbent and odor-inhibiting material, so-called cat litter, as described, for example, in a preferred embodiment in DE-OS 2902079.9-43 is.

The problem with such cat toilets is that the cat litter has to be replaced at regular intervals. Simply tipping the cat toilet into the trash can or the like is unsanitary, with dust and odor nuisances being unavoidable. It is therefore desirable to be able to replace the cat litter in a hygienic and non-dusty manner in such cat toilets provided with cat litter. From US-PS 37 71 493 a cat toilet of the type described above is already known, in which an annular upper part is placed in the cup-shaped lower part. A revenge part of this known cat toilet is that the bag itself is without any dimensional stability, so it is necessary to insert it with relatively great care into the lower part in order to achieve a reliable fit, since there is otherwise a risk that the Pulling out the upper bag area over the circumferential edge of the lower part cat litter falls out of the bag. Similar litter boxes are known from DE-OS 26 13 659 and from US-PS 39 90 396, while DE-OS 31 17 900 a double bag for the disposal of faeces in the pet keeping of small animals is known, which is closed again after use and then is thrown away, resulting from the relatively complicated structure, in addition to the considerable manufacturing costs, a high cost of materials and the associated considerable costs.

The object of the invention is to create a cat toilet of the type mentioned at the outset, which, while being inexpensive to produce, ensures hygienic handling both during use and during disposal, in particular a bag which can be used and can be filled with cat litter , inexpensively as far as possible automatically manufactured and - if necessary. for other applications also with other pourable material - should be fillable; further intended by the invention, a film pack and a method of genus be created in a manner that ensures the solution of the aforementioned task.

According to the invention, a cat toilet of the generic type is proposed for this purpose, which is characterized in that the lower part has essentially the shape of an open rectangular box; that the upper part is designed as a substantially rectangular frame; and that the bag has the shape of a flat cuboid, the outer dimensions of which essentially correspond to the inner dimensions of the lower part.

As an alternative to this, it can be provided according to the invention that when the lower part is cup-shaped, the upper part has the shape of a ring; that the bottom of the bag is made of a semi-rigid material shaped according to the bottom of the lower part; and that the bottom of the bag is provided with a stabilizing collar strip.

It can further be provided according to the invention that the bag is sealed by means of a film or the like placed over the collar strips.

The invention also provides, if necessary, that the upper end region of the bag is folded over and provided with a closure fastened by the envelope.

Furthermore, the invention proposes a film pack of the generic type to achieve the object stated above, which in the inventive Further development is characterized in that the bag has an outer envelope in the form of a flat film tube, which is sealed at two opposite longitudinal ends on the one hand and along a narrow connection area extending over its underside from one end to the other by heat sealing or the like; that on the upper side of the outer shell opposite the connection area there is a longitudinal perforation which extends essentially from one longitudinal end to the other longitudinal end parallel to the connection area, but ends at a distance in front of the respective transverse sealing seam, and two transverse perforations running parallel to and near the transverse sealing seams, with the longitudinal perforation T-shaped connection are provided; and that a flat inner tube made of film material or the like connected at its ends to the longitudinal ends of the outer shell in the transverse sealing seams is arranged on the top layer of the outer shell, which has the longitudinal perforation and the transverse perforations, and which is joined by a butt line parallel to the longitudinal perforation of the top layer of the outer shell, along which line the inner tube material is connected to the outer casing, in the material layer adjacent to the outer casing provided with the butt line, two cross-perforation lines corresponding essentially to the transverse perforations of the outer casing and in the material layer facing away from the outer casing has a central perforation lying parallel to the transverse perforation lines.

It can be provided that the two layers of the inner tube are connected to one another essentially flat by means of a "peel-off" adhesive connection. Finally, the invention proposes a method of the generic type, which in a further development according to the invention is characterized in that a film web provided on one side with the inner tube and like this having the corresponding perforations is pulled off from a supply roll, provided with the corresponding sealing seams, forming a bag, with the pourable Material filled and then processed to separate the respective bag with separation and sealing of the last, closing sealing seam.

The cat toilet according to the invention is not only inexpensive to manufacture, namely that the bags used, preferably completely made of plastic, can be easily filled with cat litter and brought to the consumer without any dust nuisance, but also ensures perfect, hygienic after use Disposal by provisionally resealing the pouch in question, optionally using a closure thread, and then easily putting it in the trash can or the like. For the user, the hassle of handling loose cat litter is completely eliminated.

Of course, the bag proposed according to the invention is suitable only when used for a cat toilet according to the invention, rather the idea of the invention encompasses the use of such a bag for foil packs, in particular for free-flowing goods, with other types of animal stalls, animal feed etc. also to be considered is. Further features and advantages of the invention result from the description below, in which exemplary embodiments are explained in detail with reference to the schematic drawing. It shows:

Inserting a bag in the exemplary embodiment of the cat toilet, as is the subject of FIGS. 4 to 6, in the lower part and placing the upper part after opening the bag in various, successive application steps.

As shown in FIG. 1, the cat toilet has a lower part 10 in the exemplary embodiment described there Lower part 12 and a bag 16 receiving a cat litter 14. In order to make the cat toilet usable, the bag 16, the bottom of which consists of a semi-rigid material shaped according to the shape of the bottom of the lower part 10, is first inserted into the lower part 10, which is designed here in the form of a circular bowl. An upper end region 18 of the bag 16 is turned around the upper edge of the lower part 10 in the catfish so that the inner wall of the cup-shaped lower part 10 is completely covered with the bag material, preferably plastic film. Then the ring-shaped upper part 12 is placed on the upper edge of the lower part 10 which is covered with the upper end region 18 of the bag 16, whereby the upper end region 18 of the bag 16 is covered and secured.

To replace the cat litter soiled after repeated use by the cat, the upper part 12 is removed upwards from the lower part 10, on which it has a snug fit, with the interposition of the material of the bag 16. The upper end region 18 of the bag 16 is detached from the upper edge of the lower part 10 and closed by pulling on a closing thread guided in a top lay of the upper end region 18 of the bag 16. Then, the bag 16 shown in Fig. 2 containing the dirty Xatzenstreu 14 can be easily removed.

Then a new bag is prepared for use in the cat toilet. Fig. 3 shows one of the like, still packaged bag 16, which is enclosed with an annular collar strip 20, which gives it the strength necessary for handling purposes, in particular also for distribution. This collar strip 20, which contains the bag with fresh cat litter 14 therein, is surrounded on all sides by a plastic roll, as a result of which the contents of the bag are protected against the ingress of moisture in particular if the bag 16 should not consist of plastic film, but of paper or the like. Before inserting the bag 16 with the fresh cat litter 14, the film and collar straps 20 are removed, the bag 16 is erected (FIG. 1) and the cat toilet is assembled in the manner described above.

The above-described advantage that when using the cat toilet according to the invention in the embodiment shown in FIGS. 1 to 3 and described above, a simple and hygienic

It is possible to replace the soiled cat litter 14, the individual bags 16 being easy to handle in packaging suitable for distribution, can be achieved to an increasing extent in the exemplary embodiment described in FIGS. 4 to 7. 4 shows a two-part film web which rolls off a supply roll 22 and is designated as a whole by 24 and which - of course in this "web state" in the flat unfolded position - carries material for an outer casing 26 and for an inner tube 28. Both the outer shell 26 and the inner tube 28 are made of plastic film, preferably of different colors. The outer shell 26 is provided with longitudinal perforations 30 and transverse perforations connected to them in a T-shape NEN 32, 34 in the arrangement shown in the drawing, the bags 16 to be produced corresponding arrangement. The inner tube 28 has a central perforation 36 on its side facing away from the outer casing 26 and a stofillin 38 on its side abutting the outer casing 26. The regions of the inner tube 36 which are adjacent to the Stofillnie 38 and 28 abut against one another are adhesively bonded to the outer shell 26. This material layer of the inner tube 28, which is in contact with the outer sleeve 26, is provided with transverse perforation lines 40, 42 corresponding to the transverse perforations 32, 34 of the outer sleeve 26; There is a peel-off adhesive connection between the position of the inner tube 28 against the outer sleeve 26 and the position of the inner tube 28 with the butt line 38 and the transverse perforation lines 40, 42.

As can be seen in FIGS. 5 and 6, the film web 24 is formed by appropriate guidance to form a tube with a connection region 44 formed by heat sealing and lying in the pull-off direction of the film web 24. A transverse sealing seam 46 is then already formed, whereupon the resulting bag 16, which is still open on one side, is filled with the cat litter and then also provided with the further transverse sealing seam 48 and closed in this way, the transverse sealing seams 46, 48 of course also the longitudinal ends of the Connect inner tube 28 to each other. The finished, closed bag thus formed is then shown on the left in FIGS. 5 and 6, with FIG. 6 showing the side with the longitudinal perforation 30 and the transverse perforations 32, 34 on the top in the use position of the bag. Fig. 7 then leaves the use of the bag 1 6 according to the invention, as it is the subject of Fig. 4 to 7 is recognizable: In a) it can be seen how the bag 16 filled with the cat litter 14 is first opened in such a way that the outer casing 26 on the top of the bag is opened along the longitudinal perforation 30 and the transverse perforations 32, 34 is, due to the adhesive connection, the corresponding position of the inner tube 28 is also folded out, so that finally the configuration shown in Fig. 7b) results, in which the outer shell 26 is folded out with the adjacent position of the inner tube 28. Then, using the central perforation 32, the other layer of the inner tube 28 is folded out, so that the cat litter 14 is finally exposed in FIG. 7c). Fig. 7d) shows that the bag can be easily inserted into a box-shaped lower part 10 in this way, the outer casing 26 or the inner tube 28 completely covering the upper peripheral edge of the box 10. A frame-like upper part 12, similar to the exemplary embodiment according to FIGS. 1 to 3, serves to clamp the part of the bag 16 that has been pushed out onto the upper peripheral edge of the lower part 10. The upper part 12 is pulled off after use, whereupon the bag can be at least provisionally closed at least provisionally by appropriately turning up the parts of the bag 16 which were originally folded out. This enables hygienic disposal.

4 to 7 can be treated particularly inexpensively and simply in continuous processes by means of a suitably designed pollen pack manufacture machines and, in addition to its rational production, offers optimum simplicity in its use.

The features of the invention disclosed in the above description, in the drawing and in the claims can be essential both individually and in any combination for realizing the invention in its various embodiments.
