DETAILED DESCRIPTION OF THE INVENTION

[0015] Without intending to limit the scope of the invention, the preferred embodiments and features are hereinafter set forth. All United States patents cited in the specification are incorporated herein by reference. Unless otherwise indicated, conditions are 25 C., 1 atmosphere of pressure and 50% relative humidity, concentrations are by weight, molecular weight is based on weight average molecular weight and aliphatic hydrocarbons and radicals thereof are from one to four carbon atoms in length.

[0016] Referring to FIG. 1, a stand-alone enclosure incorporating the grooming apparatus of the present invention is shown. Enclosure 1 is a cylindrical container having floor 2, side wall 3 and lid 4. Corresponding hook and loop fasteners 5 are spaced around the upper edge of wall 3 and lid 4, to allow access to the interior of enclosure 1 by a pet owner. An opening 6 is provided in wall 3 and sized to be accessible by a pet and is the sole means for a pet to enter the interior of enclosure 1. While enclosure 1 is illustrated as having a cylindrical shape, the enclosure may be a rectangular prism, triangular prism, pyramid or cone. Alternatively, the enclosure may be a house, garage, room, pen or other space that cannot be accessed by the pet, without passing though the opening provided in one of the walls forming the enclosure.

[0017] Referring to FIG. 2, sheet 7 is a flexible, resilient, planar structure positioned in opening 6. In an undeflected position, sheet 7 obstructs opening 6, that is, the pet must deflect sheet 7 to gain access to the interior of enclosure 1. Sheet 7 may be formed of individual elements held together to create a planar structure, or, as in the example illustrated, sheet 7 may be cut from flat stock to create a plurality of flaps 8. The flaps may be triangular shaped, with the apex aligned towards the center of opening 6 and the base aligned around the periphery of opening 6. By way of example, sheet 7 may be made up of from 4 to 12 triangular shaped flaps.

[0018] Sheet 7 may be solid. For example, sheet 7 may be constructed from flat stock formed from a thermoplastic or thermoset polymer, such as by extrusion, molding, or other manufacturing techniques known to those skilled in the art. Alternatively, sheet 7 may be constructed from a textile material, wherein fibers and/or yarns may be formed into a woven, knitted or nonwoven planar structure, such as a fabric or felt. Examples of suitable materials of construction include natural fibers, such as cotton, wool and silk, synthetic fibers, such as polyamide, polyester, polyolefin and acrylic fibers, and combinations thereof. The fibers may be staple or filaments, and the yarns may be spun from staple fibers, or consist of monofilament or multifilament fibers. Stiffening agents, such as starches, may be applied to the sheet material, especially textile sheets, to obtain the desired stiffness and resilience.

[0019] By way of example, sheet 7 may be a nonwoven fabric or felt, which may be made by needle punching staple fibers or in situ extrusion of a thermoplastic fiber. The nonwoven fabric may incorporate low melt temperature and high melt temperature fibers that can be fused together by heating the material. The fibers may be sheath and core fibers, with a low melt temperature thermoplastic sheath. The nonwoven material may incorporate binders to maintain the shape and integrity of the sheet.

[0020] In one embodiment of the invention, flaps are cut in a nonwoven textile sheet made from a mixture of 50% polyester and 50% acrylic fibers, which has been treated with starch to increase stiffness.

[0021] The thickness of sheet 7 will depend upon the nature of the material of construction and is selected to achieve the desired deflection to allow the pet to enter the enclosure and resilience to press against the pet's torso as it passes through the opening and return to its position obstructing the opening to the enclosure. By way of example, the thickness of sheet 7 may range from 0.04 (40 mil) to 0.08 (80 mil), in particular, from 0.06 (60 mil) to 0.07 (70 mil).

[0022] Sheet 7 has a surface application of a pressure sensitive adhesive to create sufficient tack, to remove and retain pet hair. Preferably, the pressure sensitive does not transfer or leave a residue on the pet's fur. By way of example, the adhesive may be applied to sheet 7 by surface spraying, immersion, kiss roll, extrusion coating, or film lamination. The adhesive may be dried or cured to achieve the desired tack characteristics. Suitable adhesives include those made from polymers of acrylic acid and/or acrylic acid alkyl esters, butyl rubber, ethylene-vinyl acetate, natural rubbers, nitriles, such as nitrile butadiene rubber, silicone rubber and styrene block copolymers.

[0023] The pressure sensitive adhesive may be applied to one or both sides of sheet 7. Preferably, the pressure sensitive adhesive is applied to both sides of the sheet, so that the pet rubs against sheet 7 upon entering and leaving enclosure 1.

[0024] In one embodiment of the invention, the sheet having the pressure sensitive adhesive applied thereto has a tack force ranging from 5 to 60 grams per 25 mm25 mm of surface area, in particular from 10 to 40 grams per 25 mm25 mm of surface area, as measured by ASTM D 6195-03 Standard Test Methods for Loop Tack, Test Method BLoop Tack Tester and based on a numerical average of three measurements.

[0025] Referring to FIG. 2, sheet 7 is supported by frame 9, which together form cartridge 10. Cartridge 10 slides into receiver 11, positioned at the front of groomer tower 12, so that sheet 7 is centered in opening 6. The grooming apparatus of the present invention may include a second sheet 13 supported by frame 14, which together form cartridge 15. Cartridge 15 slides into receiver 16 positioned in the rear of groomer tower 12, so that sheet 13 is centered in opening 6. A pet entering or leaving enclosure 1 must pass both sheet 7 and sheet 13. The distance between sheet 7 and sheet 13 is selected to allow sufficient room for the sheets to be deflected without interfering with each other and to maximize the contact between the torso of the pet and the sheet. By way of example, for a domestic cat, the two sheets may be spaced a distance of from 2 inches to 8 inches apart, in particular, from 3 to 6 inches apart, more particularly from 4 to 5 inches apart.

[0026] Cartridges 10 and 15 may be manufactured inexpensively, relative to prior art grooming devices having bristles and molded protuberances for collecting pet hair. Accordingly, when the cartridges of the present invention become covered with pet hair, they can be disposed of, and replacement cartridges can be inserted in the receivers in groomer tower 12. Another advantage of the cartridges of the present invention is that any external parasites, such as fleas, ticks, lice and mites, that may collect on the cartridges are removed and do not reestablish themselves on the pet, when the cartridge is disposed of.

[0027] In one embodiment of the invention, the sheets forming the grooming cartridges are treated with a natural or synthetic composition capable or repelling or killing one or more of fleas, ticks, lice and mites. The composition can affect parasites collected on the sheet, or when traces of the composition transfer to the pet's fur, repel and kill parasites on the pet itself. Examples of suitable compositions include oil of eucalyptus, lavender, rosemary, rose geranium and citronella, organophosphates, carbamates, pyrethrins, and other pesticides and insecticides, such as are used on flea collars, known to those skilled in the art.

[0028] Groomer tower 12 incorporates a means to direct food and water from the upper portion of enclosure 1 to receptacles positioned on the upper surface 17 of floor 2. Food supply port 18 located in the top of groomer tower 12 and directs food down chute 19 to food dish 20. Water supply port 21 located in the top of groomer tower 12, on the opposite side from food supply port 18, and directs water down chute 22 to water dish 23. Referring to FIG. 3, slot 24 in lid 4 allows access to food supply port 18 and water supply port 21, without having to lift lid 4. Separator 25 between food supply port 18 and water supply port 21 directs food and water into the appropriate dish.

[0029] Referring to FIG. 3, dishes 20 and 23 may be secured to floor 2 by corresponding interlocking components, such as hook-and-loop fasteners, e.g. Velcro attached to the respective parts. Groomer tower 12 may be secured to floor 2 by interlocking components such as tabs 26 extending from the bottom of groomer tower 12 that engage slots 27 in floor 2.

[0030] Wall 3 of enclosure 1 may be constructed from multiple interlocking sections. Accordingly, wall sections 3(a), 3(b), 3(c), 3(d), 3(e), 3(f), and 3(g) may interlock with each other and door frame 3(h) to form wall 3. Wall sections 3(a)-(h) can be provided with tabs to engage slots in floor 2, to form enclosure 1. In the embodiment of the invention shown in FIG. 3, wall sections 3(b), 3(d) and 3(f) are inserted first into floor 2, and wall sections 3(a), 3(c), 3(e) and 3(g) are slid down the adjacent wall section and inserted into floor 2. Referring to FIG. 4, ridge 28 along the side edge of wall section 3(a) is inserted into groove 29 in wall section 3(b).

[0031] The parts that make up the floor, walls, groomer tower, door frame, dishes and lid of the grooming apparatus may be formed from thermoplastic resin, such as by injection molding or other manufacturing process known to those skilled in the art. By way of example, the floor, walls, groomer tower, door frame, and dishes may be polypropylene or acrylonitrile butadiene styrene (ABS), whereas the lid may be a transparent material, such as polycarbonate or acrylic resin, including polymethyl methacrylate.

[0032] The grooming apparatus may be sold unassembled, with the parts being provided loose in a flat box. The interlocking components can be designed to create a snap-fit connection, and the apparatus can be assembled without tools.

[0033] In an alternative embodiment of the invention, a litter box may be placed on floor 2, instead of or in addition to the food and water dishes. As with the food and water dishes, the litter box incentivizes the pet to regularly enter the enclosure, at which time the pet is groomed and loose hair is collected on sheets 7 and 13.

EXAMPLES

[0034] A nonwoven textile sheet was made from a mixture of 50% polyester staple fibers and 50% acrylic staple fibers, by weight, was formed by needle punching. The sheet had a thickness of 0.060 inches (60 mils). The sheet was treated with starch and dried to increase stiffness. The sheet was lightly coated with a 100% acrylic based, pressure sensitive adhesive. Side 1 and side 2 of the sheet were provided with an add-on of adhesive (solids) of approximately 3 oz per square yard and 1.5 oz per square yard of sheet, respectively. The sheet was cut into 3 inch by 3 inch squares and submitted for testing.
