DETAILED DESCRIPTION

The present invention discloses an exemplary litter box kit 5. The litter box kit 5 includes a litter box with a curved floor. The curved floor is further discussed below.

The litter box 10 is now discussed with respect to FIG. 1. FIG. 1 is a perspective view of the litter box 10. In one embodiment, the litter box 10 may include a housing 12 and a hood or cover 14. The hood 14 is coupled to the housing 12.

As best shown in FIGS. 2-3, the housing 12 has a semi-cylindrical or curved floor 16 and two end walls 18 extending therefrom to create a litter box setting. The curved floor 16 extends in an upward direction to form two arched or curved sidewalls 20, terminating in a peripheral edge 22. The curved floor and the side walls may be configured such that their formation produces no interior corners in the exemplary embodiment. The end walls 18 join the curved sidewalls in forming the peripheral edge. The end walls may also be curved or arched. The end walls and the curved floor may be configured such that their formation include no interior corners in the exemplary embodiment.

The housing 12 may be made of a polymeric material. For example, the housing 12 may be formed of a styrene material or a polypropylene material, among other materials.

As shown in FIGS. 2-3, the housing 12 includes a stand assembly 24. The stand assembly 24 is coupled to an outer surface 26 of the curved floor 16. The stand assembly 24 may be molded or affixed to the curved floor 16. The stand assembly 24 supports the curved floor 16 and stabilizes the housing when resting on a generally flat support surface. The stand assembly 24 may include a first stand member 28 and a second stand member 30. Each stand member 28, 30 includes a first surface 32 and a second surface 34. The first surface 32 is concave to contour to the outer surface of the curved floor 16. The second surface 34 is typically flat to rest stability on the support surface. Alternatively, the housing may include a plurality of legs to support and stabilize the housing when resting on a generally flat support surface. Either the stand assembly or legs may include frictional surfaces to minimize slippage when the litter box is placed on a surface. Exemplary frictional surfaces include rubber or roughened feet, or feet formed from another suitable material such as a soft plastic, thermoplastic or suitable resin.

The stand assembly 24 may be made of a polymeric material, such as a styrene material or a polypropylene material. Alternatively, the stand assembly 24 may be made of a metal or a wood material among other materials.

Referring to FIG. 1, the hood 14 covers the housing 12. The hood 14 includes a curved or semi-cylindrical ceiling 36 and end walls 38 extending therefrom. The curved ceiling 36 extends in a downward direction forming curved or arched sidewalls 40 that terminate in a peripheral edge 42. The end walls 38 form a portion of the peripheral edge 42. An opening or doorway 43 may be formed in at least one of the end walls 38.

The hood 14 is rotatable to allow opening and manipulation thereof. The hood 14 includes a handle 44. The handle 44 allows a user to manipulate the hood 14 for easy installation and removal.

The hood 14 may be made of a polymeric material. For example, the hood 14 may be made of a styrene material or a polypropylene material among other materials. In addition, the hood 14 (or another portion of the litter box 10, such as a wall) may include a filter opening or chamber (not shown). The filter chamber may be formed in the hood and accept a filter for reducing or eliminating odors from used litter or animal waste. One exemplary filter is made of charcoal.

The litter box kit 5 may also include a litter scoop (not shown). A portion of the litter scoop may be curved to match contours of the floor 16 and arched walls. As the scoop neatly matches the floor 16, the scoop allows for clean and easy sifting of the litter and gathering of waste material.

As shown in FIG. 4, another embodiment of the present invention may take the form of a method 100 of manufacturing a litter box. The method 100 includes forming a container having a curved floor and a plurality of walls that extend in a generally upward direction from the curved floor at operation 110. The operation 110 of forming the plurality of walls further includes forming the plurality of walls such that at least one of the plurality of walls includes an arched wall. Alternatively, the arched wall may be formed separately, as in operation 112, and affixed or attached to the curved floor. The plurality of walls terminates in an edge that is spaced apart from the floor.

The method 100 may also include forming a cover having a curved ceiling wall extending in a generally downward direction at operation 114. The curved ceiling wall terminates in a second edge that is spaced apart from the ceiling. The covering is also adapted to couple to the container.

The method 100 may include forming an aperture in at least one of the ceiling walls to allow an animal to enter the container at operation 116. As an alternative, a wall may be molded in such a manner that the aperture is formed therein and no separate operation is necessary to form the aperture. Additionally, the method 100 may include coupling a handle to the cover 118. The method may further include coupling a stand assembly to the container at operation 120.

Generally, the various forming operations discussed herein may take the form of molding the litter box elements from a plastic, resin, or other suitable material.

Although the present invention has been described with reference to preferred embodiments, persons skilled in the art may recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
