Pet food package and dispenser

Abstract: A pet or animal food package and dispenser includes a food container (12) having a bottom portion (68) which defines a discharge opening (90). A removably closure or seal (94) is secured to the container (12) for retaining a pet food product therein. A dispensing tray (14) includes a forward portion defining a feeding area (26) and a rear portion (28) defining a container mounting area. The portions are joined by a sloping ramp (38). A cooperating track (52,54) and groove (56,58) arrangement on the container and tray removably mount the container to the dispensing tray.

Description: The present invention relates to pet or animal food packaging and more particularly to a device for storing and dispensing pet foods. Heretofore, a wide variety of methods have been proposed for packaging and/or dispensing pet or animal foods. Typically, foods such as those for cats, dogs and other small pets are packaged by the producer in boxes or bags. A pet owner will dispense the food into a dish or bowl each time the pet is fed. Feeding the pet, therefore, becomes a daily chore. Attempts have been made to provide pet food feeders which store an extended supply of food and dispense the food into a tray upon demand. Such feeders eliminate the daily feeding chore. Such devices typically include a food container and a tray. If the container is made separable from the tray to facilitate filling, provision must be made to interconnect the container and tray to avoid inadvertent spilling. The attachment method must be sufficiently secure to prevent the pet from separating the container and tray while still permitting easy separation by the pet owner. An example of one such pet food dispenser may be found in U.S. Patent No. 4,034,715 entitled "Convertible Pet Feeder and Method". The feeder disclosed therein includes a separable feeding tray and a container. The container is adaptable to hold and deliver dry pet foods or liquids. An example of another such device may be found in U.S. Patent No. 4,840,143 entitled "Pet Food Dispenser". A further example of a pet food dispenser is given in U.S. Patent No. 3, 763, 826. This dispenser is similar to that of the present invention in that it includes a separable container and feeder tray. However, this device differs from that of the present invention particularly in the means for attaching these two components. U.S. Patent No. 4, 281, 624 also discloses a pet food dispenser in which a one-piece container and feeder tray has a single opening for both filling with and dispensing food. The dispensing devices or feeders heretofore provided have been sold separately from the pet or animal food. The pet owner is required to fill the food supply container each time the device is used. A need exists for a pet food dispenser and packaging system which may be filled by the food producer and purchased by the pet owner. A need exists for a pet food dispenser which is easily useable, relatively inexpensively manufactured and which is reliable in use. In accordance with the present invention, the aforementioned needs are substantially fulfilled. Essentially, an animal or pet food container is provided which includes joined walls and defines a discharge opening. A removable closure closes and seals the discharge opening so that the container may be used as the sales packaging for the animal food. In addition, a dispensing tray is provided which defines a forward, feeding area and a rear mounting or container support area. Provision is made for removably interconnecting the dispensing tray and the food container via a pair of spaced, generally parallel, elongated guide tracks which cooperate with correspondingly configured grooves formed in the side of the container to mount the container on the tray. In accordance with the present invention, the food container is filled by the producer and sold to the pet owner. The closure means is readily removed and the container is joined to the dispensing or self feeder tray or base. It is presently preferred that the container and tray be molded plastic items and that the container define an integral carrying handle. The invention is further illustrated with reference to the accompanying drawings, in which: Figure 1 is a side elevational view of a pet or animal food dispenser including a container and feeding tray in accordance with the present invention; Figure 2 is a perspective view of a feeding tray in accordance with the present invention; Figure 3 is a top plan view of the feeding or dispensing tray of Figure 2; Figure 4 is a cross sectional view taken generally along line IV-IV of Figure 3; Figure 5 is a front elevational view of a pet food container in accordance with the present invention; Figure 6 is a side elevational view of the container; Figure 7 is a rear elevational view of the container; Figure 8 is a bottom plan view of the container; and Figure 9 is a top plan view of the container. A preferred embodiment of an animal or pet food dispenser in accordance with the present invention is illustrated in Figure 1 and is generally designated by the numeral 10. Dispenser 10 includes a container or food package 12 and a base, or dispensing or feeding tray, 14. Container 12 and base 14 are selectively interconnectable, as discussed in more detail below, to form a self feeder. As seen in Figures 2, 3 and 4, the base or dispensing tray 14 has a tiered shape and includes a peripheral wall 16. Wall 16 includes an outer wall 18 and a joined inner wall or surface 20. A forward portion 22 of tray 14 includes a bottom 24 which, in conjunction with wall surface 20, defines a forward feeding area 26. A rear portion 28 of tray 14 defines a container mounting area. Portion 28 includes a generally planar support surface 30 joined with ledges 32. Ledges 32 extend outwardly towards portion 22 along lateral edges 34 and 36 of portion 28. As best seen in Figures 2 and 4, bottom 24 and surface 30 are joined by a curved or sloping ramp 38. Wall 16 extends upwardly above surface 30 and ledges 32. Wall 16, therefore, includes a rear wall portion 42 and side wall portions 44 and 46. A container mounting structure is formed integral with side wall portions 44 and 46 of tray 14. As shown, the mounting structure includes a pair of elongated, laterally spaced, parallel guide tracks or flanges 52 and 54. Tracks 52 and 54 extend generally parallel to and spaced above ledges 32 and 34 respectively. Flange or guide track 52 extends rearwardly along a substantial portion of the lateral edge of support surface 30. An upper surface 56 of track 52 defines a slot or notch 58. Guide track 54 is identical in configuration to track 52. The tracks and their corresponding notches 58 cooperate with the container 12. It is presently preferred that tray 14 be moulded as a one-piece member from a suitable plastics material. As seen in Figures 5 - 9, container 12 includes spaced side walls 60 and 62, a front wall 64, a rear wall 66, a base portion 68 and a top portion 70. In the preferred form, front and rear walls 64 and 66 diverge outwardly with respect to one another from base 68 upwardly towards the top portion 70. Side walls 60 and 62 extend in spaced, parallel relationship to each other. Upper portion 70 includes a handle 74 defined by upwardly extending container portions 76 and 78 which are joined by a flat surface 80. A handle defining member 82 extends in spaced relationship to surface 80. Member 82 and surface 80 define an aperture 84. Handle member 82 and aperture 84 are dimensioned so that a purchaser may readily grasp container 12 at the handle portion for transport. Bottom portion 68 of container 12 is formed with a discharge opening 90 (Figure 8). In the presently preferred form, opening 90 is a circular aperture formed in a generally planar surface 92 of base portion 68. In accordance with the present invention, container 12 is filled with a suitable pet food of the dry, flowable variety at a food producers' facility. A closure or seal means 94 is then applied to planar portion 92 to close and seal the discharge aperture 90. It is presently preferred that the closure 94 be a flexible foil sheet 96 cut and secured to portion 92 by a suitable peelable adhesive 98. Bottom portion 68 of container 12 further includes spaced side walls 102 and 104 and a rear wall 106. As seen in Figures 7 and 8, walls 102 and 104 and rear wall 106 are offset or spaced inwardly slightly from side walls 60 and 62 and rear wall 66 of container 12. The walls are dimensioned to be received within dispensing tray rear portion 28. The walls define a peripheral ledge 110 which will rest on an upper surface of walls 42, 44 and 46 of the dispensing tray. Side walls 102 and 104 of bottom portion 68 define elongated, generally parallel grooves 114 and 116. Grooves 114 and 116 open rearwardly through wall portion 106. In addition, downwardly extending tabs or detents 118 are defined by side walls 102 and 104. Detents 118 extend into the grooves of the side portions. The detents are positioned to cooperate with and be received within detent notches 58 formed in the guide tracks 52 and 54 of the dispensing tray and retain the container on the tray. Container 12 is also preferably moulded as an integral one-piece member from a suitable plastics material. In view of the above description, the operation of the present invention should now be readily apparent. A pet food producer or supplier will fill container 12 with a suitable quantity of pet food. Subsequent to the filling operation, closure means 94 is applied to seal the food. The pet owner may purchase the containers individually to use with a single feeding tray. In use, the removable closure means or foil seal is peeled off of the bottom portion of the container. When held in an inverted position, the container 12 may be slipped onto dispensing tray 14 by inserting guide tracks 52 and 54 into grooves 114 and 116. The tabs or detents 118 will snap into notches 58 formed in the guide tracks. The rounded forward ends of the tracks will cam the detents into the notches. Since container 12 is moulded as in integral unit from a plastics material, it has sufficient flexibility to permit the tray and container to be interconnected. Bottom portion 68 of the container at surface 92 is supported by ledger 32 and rear support surface 30. The container abuts rear wall 42 and the tabs or detents are received within the notches. As a result, the container is securely retained. The container may not be moved backwardly and separated from the tray. Forward movement is resisted by the detents. The flowable food will exit discharge aperture 90 and slide down ramp 38 into feeding area 26. As food is consumed by the pet, the tray is automatically filled. The configuration of the container including the diverging front and rear walls 64 and 66 ensures that food flows to the discharge opening. The package, container and tray in accordance with the present invention permit the efficient packaging, transport and sale of pet food. Separate filling of a dispensing container is eliminated at the pet owner level. A multiple day supply of food is provided. The container is securely mounted on the tray yet easily removable by the pet owner. The mounting arrangement prevents inadvertent or accidental separation by the pet of the tray and the container. The tray is dimensioned to provide a stable platform or base so that the combination will not tip during normal use. The container may be reused after it is emptied or a new container and food package can be purchased by the owner. In view of the foregoing description, those of ordinary skill in the art may envision various modifications. For example, the handle could be fabricated as a separate item and attached to the container.
