This invention relates, in general, to devices and methods for collecting solid pet waste and, in particular, to devices which may be manually manipulated to pick up and dispose of animal waste in a container and to a method of utilizing such devices with no or minimal manual contact with the waste-holding container.
Even though the collection of animal and pet waste material, including excrement and vomit, is mandatory and required by municipal ordinance in many cities and towns, the vast majority of pet owners collect pet waste as a matter of general courtesy and environmental respect. This is true despite the fact that the collection of pet waste is an undesirable practice due, in part, to the warm pliable nature of pet waste. Currently, the most common method for collecting pet waste material is placing a plastic bag over the hand to fashion a free-form glove.
The pet waste material is then scooped up in the hand and, once collected, the bag is removed from the hand in an inside-out fashion to capture the pet waste in the plastic bag for proper disposal.
A collection device for pet waste material and method for use of the same. In one embodiment, a pair of opposing shells extend from a base at which there is pivotally attachment of the opposing shells. The pair of opposing shells are pivotally movable between a closed shell state with the respective shell ends proximate each other and an open shell state wherein the shell ends are spaced from each other. A bag when folded upon itself may have its pouch inserted into the collection device and held therein between the pair of opposing shells. A pair of pockets are respectively coupled to each of the outer surfaces of the shells and configured to accept fingers for grasping and manipulating the collection device between the closed shell state and the open shell state.
For a more complete understanding of the features and advantages of the present invention, reference is now made to the detailed description of the invention along with the accompanying figures in which corresponding numerals in the different figures refer to corresponding parts and in which:
While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts which can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the present invention.
Referring to
The pair of opposing shells 12, 14 are pivotally affixed at the base 16, which may include a living hinge which permits the opposing shells 12, 14 to flex preferentially at the living hinge in response to a bending force or urging from a human hand. In particular, in one embodiment, the opposing shells are pivotally affixed at the base 16 in a non-biasing relationship by the living hinge. A pair of pockets 22, 24 are respectively coupled to each of the outer surfaces. Each of the pair of pockets 22, 24 is configured to accept fingers or a thumb, depending on how the collection device 10 is held in the hand.
The pair of opposing shells 12, 14 are pivotally movable between a closed shell state with the respective shell ends proximate each other and an open shell state wherein the jaw ends are spaced from each other. In the open shell state, the opposing shells 12, 14 are adapted to accept a pouch of a bag liner. As will be discussed in further detail below, by way of manipulation of the fingers and thumb, the opposing shells 12, 14 may transition between the open shell state and the closed shell state.
Referring to
Support members 30, 32, 34, and 36 support respective foldable flaps 26 and 28 in the first and second positions. Support members 30, 32, 34, and 36 also limit a distance 54 that proximal ends of the foldable flaps can travel away from the outer surfaces of respective shells 12 and 14. Support members 30, 32, 34, and 36 are affixed to an edge of respective foldable flaps 26 and 28 and to its respective shells 12 and 14. Alternative embodiments may have a support member affixed to one of an edge of a foldable flap and its respective shell.
Additionally, support members 30, 32, 34, and 36 may be affixed to respective shells 12 and 14 via a tabs 38, 40, 42, and 44 at one end of each of support members 30, 32, 34, and 36. Tabs 38, 40, 42, and 44 fit into respective slots 46, 48, 50, and 52 of shells 12 and 14. After tabs 38, 40, 42, and 44 are passed through slots 46, 48, 50, and 52, support members 30, 32, 34, and 36 may slide freely through slots 46, 48, 50, and 52.
The tabs 38, 40, 42, 44 may be sized and designed to facilitate passing the tabs through the slots 46, 48, 50, and 52 easily in one direction but not on the other. In doing so, the distance 54 that the proximal ends of the foldable flaps 26 and 28 can travel is limited. As illustrated, tab 42 comprises a leading edge with rounded portion 62 and a trailing edge with flat portion 64. Rounded portion 62 allows the support member 34 to pass through the outer surface of shell 14 via slot 50 so that foldable flap 28 may be closed into the first position. When foldable flap 28 is subsequently opened, the flat portion 64 contacts the inner surface of shell 14 and prevents the foldable flap 28 from opening past the distance 54, thereby supporting the second position.
Additionally, embodiments of the collection device 10 may be formed via a single mold as a single piece of thermoplastic material. In doing so, the molding and assembly costs of the collection device 10 are reduced.
Referring to
In one embodiment generally illustrating liner bag installation, the pouch of a liner bag is inserted into the collection device 10 which is positioned in the open state. A bag mouth of the liner bag is thereby formed at the intersection of the liner bag and the respective lips of the pair of opposing shells 12, 14. The liner bag may then be folded upon itself and the collection device 10 such that the bag mouth is removably inserted into the collection device and held therein between the pair of opposing shells 12, 14. The respective opposing lips extend from an edge of each of the opposing shells and in a tapered form. The opposing lips move in a mandibular motion toward and away from each other to releasably grip the liner bag and its contents.
Referring to
The user may then unfold the portion of the liner bag 66 that was previously folded upon itself and over the collection device 10. A twist or knot created with the liner bag or other fastener may then be used to seal liner bag and close the pet waste material into the pouch 68 of the liner bag 66. The collection device 10 may then be returned to the open shell state through manipulation by the hand (not shown). With the liner bag 66 released and waster material securely captured, disposal may then be made.
As previously mentioned, the collection of pet waste material is an undesirable practice due, in part, to the warm pliable nature of pet waste, as shown in part by the heat H emanating from the pet waste illustrated in
It should be appreciated that variations on the general operation are within the teachings presented herein. For example, the collection device 10 may be operated in a scoop-like manner in the event that waste material is not deposited in a single location. In this case, the collection device 10 may be used in a scoop-like manner to gather all waste in a single location before the collection device 10 is used in a manner to that previously described.
While this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications and combinations of the illustrative embodiments as well as other embodiments of the invention, will be apparent to persons skilled in the art upon reference to the description. It is, therefore, intended that the appended claims encompass any such modifications or embodiments.
This application claims priority from U.S. Patent Application No. 61/325,997, entitled “Collection Device for Pet Waste Material” and filed on Apr. 20, 2010, in the name of Craig A. Hoffman; which is hereby incorporated by reference for all purposes.
