BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to new and novel improvements in pet food and water bowls. More particularly, the present invention relates to a covered pet food and/or water bowl, such as a stainless steel pet feeder having a cover that is preferably durable and lightweight, and provides an aesthetically pleasing appearance, protection to both the bowl and the surface on which the bowl may be set upon, and possibly some insulating properties to the contents placed therein.
2. Description of the Related Art
In the related art, a few covered bowls and covered container articles are disclosed. For example, U.S. Serial No. 2,731,056, issued in the name of Anson, discloses a unitary molded body that preferably is made of an elastic rubber-like material that can be a plasticol and has an endless series of pronounced pleats extending axially of the body. The body can serve as a coaster for a glass or for other containers having various sizes and shapes, including flower pots, milk bottles, and soda bottles, and can serve as a protective sleeve for various objects. However, such a device as described in Anson cannot be utilized as a pet food and water bowl.
Further, U.S. Pat. No. 5,979,361, issued in the name of Willinger, discloses a non-skid pet bowl comprising a bowl having molded over it a non-skid thermoplastic elastomer that covers the bowl's undersurface and desirably runs midway up the bowl's sidewall. The bowl is first molded from plastic, and then the thermoplastic elastomer is molded as a coating or layer over it. However, such a device cannot be used directly for stainless steel bowls, and does not anticipate a separate cover that is affixed to the stainless steel bowl via an inference fit.
Finally, U.S. Pat. No. 1,922,127, issued in the name of Foley, discloses a pail silencer made of a single piece of resilient material, such as rubber, and including a cup designed to receive and grip the lower end of the pail. Again, however, such a device cannot be utilized as a pet food and water bowl, cannot be used directly for stainless steel bowls, and does not anticipate a separate cover that is affixed to the stainless steel bowl via an inference fit.
Given the particular advantages of providing an anti-microbial growth surface environment when used with stainless steel that are particularly well suited for use in pet food and water bowls, and given the tremendous and immediate commercial success of applicant's DURAPETTM brand pet food and water bowls, it is felt that the improved covered bowl of the present invention provides these advantages while avoiding the shortcoming of the prior art.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved covered pet bowl having an altered external appearance.
It is another object of the present invention to provide a covered for a pet bowl that minimizes and substantially precludes the bowl from slipping and sliding along or across a surface, such as a floor, upon which it is placed.
It is a further feature of the present invention to provide a covered pet bowl that can provide some level of insulation for the contents of the bowl placed therein.
Briefly described according to the preferred embodiment of the present invention, the aforementioned objects of the present invention are attained by a stainless steel pct bowl having a cover secured to the exterior surface of a bowl such as by molding or adhesive attachment. The cover may also be manufactured by various other known means for shaping plastic or rubber type materials. The cover may provide a pleasing aesthetic appearance, as well as providing protection to the bowl's bottom or the surface on which the bowl may be placed. In an alternate embodiment, the cover is not adhered or molded on, but rather has a slight to zero interference fit with the exterior surface of the bowl to normally remain on the exterior surface of the bowl when the bowl is lifted or otherwise moved. The cover's inner surface is then substantially formed to the shape of the bowl to fit over the outer surface of the bowl. In the preferred embodiment the covered bowl is formed as a single unit; in the alternate embodiment, the cover is removable from the bowl or can be provided separately. In either embodiment the cover may be fabricated from various materials such as rubber or plastic based material to provide resistance to substantially prevent the bowl from slipping, sliding or otherwise moving during use by the pet, and further preventing scratching, scarring and annoying noises that may result from sliding on a floor. Finally, if formed of sufficient thickness the cover can provide insulation to the contents placed within the bowl.
Other advantages and novel features of the present invention will become apparent in the following detailed description of the invention when considered in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 8.
1. Detailed Description of the Figures
Referring now to FIG. 1, a covered bowl 10 is shown in accordance with a preferred embodiment of the present invention. It is envisioned that the covered bowl 10 has an aesthetic outer cover 40 placed about the lower exterior of the bowl 50 and can be affixed thereto by a variety of methods, including molding or manual manipulation or adhesive attachment of a separately provided cover 40 onto the outer lower periphery of the bowl 50. Preferably, the cover 40 is attached about the exterior of the bowl 50 via a suitable adhesive or by directly molding the cover 40 onto the bowl 50, whereby the cover 40 remains affixed to the bowl 50 during lifting, moving or repositioning. As shown best in conjunction with FIG. 3, a permanent or semi-permanent adhesive 51 can be placed within the cover 40, onto the bowl 50, or both.
The bowl 50 may be of various designs, such as the one depicted in FIGS. 1-6, comprising an annular sidewall 52 depending from a bottom surface 54, wherein the sidewall 52 terminates at an upper peripheral rim 53 opposite the bottom surface 54 that is coextensive with a bowl opening 56. The sidewall 52 and bottom surface 54 each have an exterior surface, wherein the exterior and interior surfaces of the sidewall 52 are denoted as 60 and 62, respectively, and the exterior and interior surfaces of bottom surface 54 are denoted as 64 and 66, respectively. As shown in conjunction with FIGS. 7-8, other bowl designs can be adapted to use the present invention.
Referring now specifically to FIG. 4 through FIG. 6, an alternate embodiment is shown in which the cover 40 is a separable body comprising a continuous sidewall 12 depending from a base 14, the sidewall 12 being available in various heights and widths, and the base 14 also being available in various widths or thicknesses. The height of the sidewall 12 may vary between de minimis, wherein the sidewall 12 extends upward just beyond the junction of the sidewall 12 and base 14, to a maximum, wherein the sidewall 12 extends upward to cover the height of the sidewall 52 of bowl 50. It should be noted that FIG. 4 through FIG. 6 illustrate a cover 40 that substantially traverses the entire height of sidewall 52 of bowl 50, but traversal of sidewall 52 is not required or necessary. In this embodiment, frictional force and interference fit securely hold cover 40 on bowl 50, it is the circumferential contact between the exterior surfaces 60 and 64 of bowl 50 and the interior surfaces 18 and 22 of cover 40 that provides the frictional interference fit. Thus, the cover 40 only needs to extend upward as is necessary to secure the cover 40 to the bowl 50 by frictional interference fit.
2. Operation of the Preferred Embodiment
To use the present invention, in accordance with a preferred embodiment of the present invention, a cover 40 is placed upon a bowl 50 to provide protection to the bowl 50, reduce slipping and sliding of the bowl 50 during use by a pet, and provide insulating properties to the contents of the bowl 50. The cover 40 may be fabricated onto the bowl 50 during manufacture, or may be manually placed thereon. When a pet eats or drinks from the bowl 50, the cover 40 resists movement by the glutinous properties of the cover 40 adhering and frictionally impinging the cover 40 to a surface.
The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, and enable others skilled in the art to best utilize the invention and various embodiments. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents. Therefore, the scope of the invention is to be limited only by the following claims.
