although the present invention guard device can be applied to many different types of feeding bowls and containers , the present invention guard device is especially well suited for use with a simple round dog feeding bowl . accordingly , in the exemplary embodiments of the invention that are shown , the present invention guard device is shown with a traditional round dog bowl . referring to fig1 an exemplary embodiment of the present invention guard device 10 is shown with a conventional round dog feeding bowl 12 . the dog feeding bowl 12 is a bowl that has a circular open top of a first internal diameter d 1 . the top internal diameter d 1 of the dog feeding bowl 12 is typically between six inches and ten inches , if used to feed or water an average dog . smaller diameter bowls are for smaller dogs and other smaller pets , such as cats . many people utilize heavy ceramic or metal bowls to feed or water their pets . still other people use old kitchen bowls . any such bowl can be used in conjunction with the present invention guard device 10 . when a person feeds or give water to their pet , they typically fill the feeding bowl at least half full with food or water . any food or water that is displaced from the feeding bowl by the pet spills over the edge of the bowl and falls to the floor . this dirties the floor , thereby requiring that the floor around the dog bowl be cleaned often . furthermore , food or water often adheres to the hair of the pet on its snout . when the pet pauses from feeding or drinking and lifts its head from the feeding bowl , it is not uncommon for food or water to drip from the pet &# 39 ; s snout and fall to the floor . this is particularly prevalent with larger dogs that have large jowls . these spots of food and water not only dirty or wet the floor , they present potential slipping hazards if inadvertently stepped upon . the present invention guard device 10 is a guard that attaches to the top of the dog bowl 12 and dramatically increases the area of that bowl . this increase in area prevents a dog from displacing food or water from the dog bowl 12 and catches drippings that may fall from the pet &# 39 ; s snout or jowls . the guard device 10 is an annular structure having a circular bottom edge 14 of a first diameter d 2 and a circular top edge 16 of a larger second diameter d 3 . the guard device 10 is formed into two separate sections between the bottom edge 14 and the top edge 16 . the two sections include a bowl engagement section 18 and an expanding section 20 . the bowl engagement section 18 is a cylindrically shaped section . the exterior of the bowl engagement section 18 has the same external diameter d 2 as does the bottom edge 14 of the guard device 10 . this diameter d 2 is preferably selected to be only slightly smaller than the inside diameter d 1 of the dog bowl 12 . the bowl engagement section 18 has a vertical length of between 14 inch and three inches . accordingly , when the guard device 10 is placed onto the dog bowl 12 , the bowl engagement section 18 passes into the dog bowl until either the bottom edge 14 of the guard device 10 contacts the bottom of the dog bowl 12 or the top edge of the dog bowl 12 contacts the expanding section 20 of the guard device 10 . preferably , the vertical length of the engagement section of the guard device equals the depth of the dog bowl 12 . likewise , the diameter d 2 of the exterior of the engagement section 18 of the guard device 10 matches the interior diameter of the dog bowl 12 . although a mismatched guard device 10 and bowl 12 can be used , match sets are preferable . for this reason a guard device 10 can be sold in sets with a matching dog bowl 12 . if the dimensions of the engagement section 18 of the guard device 10 closely match the dimensions on the interior of the dog bowl 12 , the guard device 10 firmly engages the dog bowl 12 and is not easily knocked away from the dog bowl 12 . the closeness in dimensions creates a friction fit that serves to retain the guard device 10 in attachment with the dog bowl 12 . if matched sets are used , the dog bowl can be created with a rim of a certain standard thickness . the guard device 10 can be manufactured with a groove that accepts the rim of the dog bowl , thereby interconnecting the dog bowl and the guard device with a mechanical attachment . once the guard device 10 is attached to the dog bowl 12 , the top edge 16 of the guard device 10 becomes the new open top to the combined bowl / guard assembly . this increases the area of the opening of the dog bowl 12 from between 25 % to 300 %. as an animal eats or drinks from the combined bowl / guard assembly , the presence of the guard device 10 prevents the dog from displacing food or water from the dog bowl 12 with its snout . furthermore , as the dog pauses from eating or drinking and lifts its head from the bowl , drippings from the dog &# 39 ; s snout and jowls will fall onto the guard device 10 and will flow back into the dog bowl 12 . as such , the guard device 10 greatly decreases the amount of food and water spillage that contacts the floor without restricting access of the dog bowl 12 to the dog . referring to fig2 an alternate embodiment of the present invention guard device 30 is shown . in this embodiment , the engagement section 32 of the guard device 30 is stepped in its configuration . the stepped configuration consists of a plurality of cylindrical sections 34 , wherein each successive cylindrical section 34 increases in diameter as they progress from the bottom edge 36 of the engagement section 32 toward the expanding section 38 . by providing a stepped engagement section 32 , the engagement section 32 is capable of engaging a plurality of different diameter bowls 12 with a friction fit . consequently , the guard device 30 can engage a plurality of different diameter bowls 12 provided one of the cylindrical sections 34 on the stepped configuration has a diameter that corresponds to the diameter of one of the bowls 12 . referring to fig3 yet another embodiment of the present invention guard device 40 is provided . in this embodiment , it can be seen that the guard device 40 has a cylindrical engagement section 42 and a curved expanding section 44 , as does the embodiment previously shown in fig1 . however , in this embodiment , at least one support structure 46 extends downwardly from the bottom of the curved expanding section 44 and supports the guard device 40 on the ground . the support structure 46 can be one continuous wall that surrounds the engagement section 44 or can be a plurality or legs that are symmetrically disposed around the engagement section 42 . the support structure 46 supports the remainder of the guard device 40 a predetermined distance above the ground . a dog bowl 12 can be placed under the guard device 40 within the space defined by the support structure 46 . as such , the support structure 46 supports the remainder of the guard device 40 over the dog bowl 12 . this enables the guard device 40 to be used with a dog bowl 12 , even though the diameter of the dog bowl 12 is much larger than that of the bottom edge of the guard device 40 . it will be understood that the embodiments of the present invention device described and illustrated are merely exemplary and a person skilled in the art can make many variations to the shown embodiment . for example , in the embodiment of fig3 it will be understood that the support structure 46 can be made as a structure that is part of the overall guard device , as shown , or it can be made as a separate detachable element . in all embodiments , the diameters , depth and slope of the expanding region of the guard device can be altered as desired . lastly , the diameters and number of cylindrical sections 34 used in the embodiment of fig2 can also be altered as desired . all such alternate embodiments and modifications are intended to be included within the scope of the present invention as defined below in the claims .
a device and method for creating an improved feeding bowl assembly by attaching a guard device to a pet feeding bowl . the guard device is a bowl shaped guard that is positioned on top of a traditional pet feeding bowl . the guard device prevents food or water from being splashed out of the feeding bowl by the pet . furthermore , the guard has a diameter that is larger than that of the feeding bowl . as such , the guard device catches drippings from the animal that would not otherwise be caught by the feeding bowl .
