After canine feces is collected on the surface of the bag blank; the bag is formed by operating the scooper device; and, then is securely closed to form a disposable bag.

## Background
1. Field of the Invention

This invention relates to a device to aid dog owners in the collection, handling and disposal of canine fecal matter, and, more particularly, to a waste disposal apparatus and a disposable bag for use in conjunction therewith. In the disposal apparatus disclosed, the bag is formed from a blank which is manipulated during use to a partially closed position.

2. Information Disclosure Statement

Numerous municipal corporations have enacted ordinances to safeguard residents from the health hazards and nuisances stemming from uncollected canine fecal matter. As such fecal material is capable of transmitting diseases, the ordinances have generally been upheld as being within the police power of the municipalities. More commonly, the press has referred to these provisions as "pooper scooper" laws and various devices ranging from specially designed shovels to elaborate gloves have been devised to aid the dog owner in the discharge of his responsibility. As will be seen in the brief background discussion which follows, the devices entail numerous technical and sanitary considerations.

The inventor is familiar with some technological developments found in the following field: CLASS/SUBCLASS ______________________________________ 294/49, 1.3, 1.5 ______________________________________

Germany DE3807221 A1 and DE 3809286 A1 to M. Bock--Mar. 5, 1988 and Mar. 19, 1988. Respectively

Disclose a dog excrement receiver mounted on the end of an extension rod to maintain the collection of canine fecal matter at arm's length from the dog owner. Bock '221 shows a catchment device and Bock '286 shows a catchment device with a handle-operated bag closure.

No patent or combination thereof shows a dog excrement catcher with a disposable bag, a drawstring or other closure, and a holder having a mechanism which forms the disposable bag from a bag blank. Also, as will be seen from the disclosure which follows, the bag blank is mounted to protect the mechanism and drawstring or other closure from being soiled. During operation, the mechanism holds the bag blank in a substantially flat position.

In general terms, the invention disclosed hereby is a canine fecal matter collection and disposal apparatus. In the mode of the invention, a bag frame is attached to one end of a handle, and the handle has a handgrip at the other end. An actuating rod extends from the frame to the handgrip and connects, adjacent to the handgrip, to a trigger mechanism. By squeezing the trigger mechanism, the frame is actuatable from a substantially flat or open position to a substantially erect or partially closed position. A bag blank for a disposable bag is provided that is adapted to mount onto the frame and has a closure means thereon. In the within invention, the closure means is a drawstring. In operation, a bag blank for a disposable bag is mounted on the frame and protects the frame from being soiled by canine fecal matter. In the open position, the device is operated so that the bag blank is substantially flat. The opened device is then used to catch the fecal matter falling from a dog. With the excrement on the flattened bag blank the actuator is released enclosing the waste in a partially closed bag. The operator completes the closure of the disposable pouch by drawing the drawstring closed, or in the case of another closure device completing the closure thereof, and pulls the disposable pouch off the frame. Because this mechanical closure is on the underside of the bag during the catchment phase, the procedure is one of enhanced sanitation which minimizes possible contact by the operator with canine fecal matter. The closed pouch is then discarded and an empty pouch is placed on the frame.

It is an object of the present invention to provide an economical device for collection and disposal of canine fecal matter.

It is a further object of the present invention to provide a device having a disposable bag portion which, in operation, is arrayed in a manner which promotes sanitary handling.

It is yet another object of the present invention to provide a device which minimizes equipment cleaning after use.

It is still yet another object of the present invention to provide a secured disposal container which container is biodegradable.

It is a feature of the present invention that the apparatus forms a disposable bag from a bag blank.

It is another feature of the present invention that the disposable bag is operable by the holding device portion between a flat, substantially open and a partially closed position.

It is another feature of the present invention to have a drawstring or closure means facilitating the removal of the used bag from the frame and completing the closure of the partially closed bag.

It is yet another feature of the present invention to have a bag which when mounted on the holding device protects the holding device from becoming soiled by canine fecal matter.

Other objects and features of the invention will become apparent upon review of the drawings and the detailed description which follow.

In the following drawings, the same parts in the various views are afforded the same reference designators.

FIG. 1 is a perspective view of the canine waste apparatus and disposable bag therefor of the present invention, said apparatus shown in the open position;

FIG. 2 is a perspective view of the invention shown in FIG. 1, but shown with the apparatus in the closed position;

FIG. 3 is a perspective view of the invention shown in FIG. 2, but shown for illustrative purposes with the disposable bag removed;

FIG. 4 is a bottom plan view of the disposable bag showing the pockets and drawstring thereof; and,

FIG. 5 is a perspective view of an inverted stack of disposable bags with the topmost bag being loaded onto the frame device.

The apparatus described hereinbelow is one which follows closely canine behavior and provides a distinct improvement in sanitary collection and disposal of canine fetal matter. The apparatus includes two basic units--the frame device and the bag blank for the disposable bag. It has been observed that a dog generally stops in a single location for defecation and that sliding a flat collection device underneath will not disturb this function. In the case at hand and in the best mode of practicing the invention, the frame device has an array of fingers upon which the disposable bag is emplaced. It is understood that alternate frame devices for bag forming can be envisioned without departing from the spirit of this invention. Many of the prior art devices have frame portions which are left uncovered by the bag placement or which expose the dog owner to hazards during handling of canine fecal matter.

Referring now to FIGS. 1 through 4, the frame device and disposable bag are shown and the sanitary device for collecting and disposing of canine fecal matter is referred to by the numeral 10. The frame device 12 is constructed with a base 14 which base is a substantially planar body. To the base, a number of finger-like elongated members 16 are hingedly attached at one end thereof at hinge 18. While finger-like elements cooperating with pockets are taught hereby, any of numerous means can be used to attach the bag blank to the frame device, including inter alia adhesive strips (such as is used for personal hygiene products for lining clothing); catchment devices that pinch part of the blank without penetrating the same; and, extra folds rather that form an origami-like drape around the frame device. The finger-like attachments 16 are constructed to be operable from an open position wherein which the fingers are substantially coplanar with the base 14 to a closed position wherein which the fingers are normal or within 15 degrees of normal to the base. While any number of finger-like projections may be used, typically three or four are chosen. Also, while many different arrangements can be employed to swing the fingers from one position to the other and back again, in the best mode, a retractable and extendable guide 20 is shown. However, it is intended that the descriptive language hereof, to wit, "guide means", apply equally to a cam-operated mechanism which would be configured differently, but function similarly. In the invention at hand, the extendable guide 20 is attached to each elongated member 16 proximate to the hinge 18 at guide aperture 22. When extended the guide 20 is substantially concentric to or encircling the base 14. When retracted the guide 20 is substantially coaxial with base 14. A shaft 24 extends from the base 14 and guides 20 and at the free end a handgrip 26 is mounted thereupon. A trigger or actuator mechanism 28 is constructed with a trigger 30 attached to the shaft 24 and adjacent the handgrip 26. A control rod or actuator linkage 32 is cooperatively functional with the trigger 30 and guide 20 and enables the retraction and extension of the guide 20. A detent or lock 34 latches the actuator 32 in the retracted position, and, upon release, the spring return [not shown] urges the actuator 32 to the extended or open position. Mechanically, it would be obvious to provide a mechanism the reverse of that just described and have the spring return urge the actuator to the retracted or closed position.

The disposable bag or pouch 38 of the device is next discussed. The bag 38 is formed from a web or blank 40 of one or more layers of a biodegradable paper or fibrous material and can be either a woven or non-woven product. The central portion 42 of the blank 40 is dimensioned to coincide with base 14 of frame device 12. The outer portion 44 is adjacent central portion 42 and is prefolded to form pleats or gussets 46 upon the frame device 12 being operated to the closed position. Although in the best mode, the bag blank 40 is used with a bag forming device, the disposable bag 38 is also useable with a flat ring-like holder. The blank 40 has an upper surface 48 which, upon the frame device 12 being operated to the closed position, forms the inner wall of the disposable bag. Further, the blank 40 has a lower surface 50 which, upon the frame device being operated to the closed position, forms the outer wall of the disposable bag. Consistent with the number of finger-like elongated members 16 of the frame device 12, a plurality of pockets 52 are attached to the lower surface 50 of the web or blank 40 in a manner radiating outward from the central portion 42. Each pocket 52 has an opening 54 adjacent the central portion. While the pockets of the best mode are shaped similar to the shape of the elongated members 16, any of a number of shapes could be adopted that would function satisfactorily. Further, a closure device or drawstring 56 is attached to the peripheral margin 58 of the lower surface 50. The drawstring 56 is retained within a drawstring holder 60 attached to the peripheral margin 58.

In operation, the disposable bag 38 is first assembled to the frame device 12. Referring now to FIG. 5, an inverted stack 62 of disposable bags 38 is shown. The stack 62 permits entry of the fingers 16 of a closed frame device 12 into pockets 52 of the topmost bag. With the fingers 16 inserted and base 12 resting atop central portion 42 of the lower surface 50, the trigger 30 is squeezed permitting the extension of guide 20 and the actuation of the frame device 12 to the open position. This "picks off" the uppermost bag 38 from stack 62. Next canine fecal matter is collected on the upper surface 48 and the trigger 30 is again operated, retracting guide 20 and moving the fingers 16 to the closed position. At this point, the disposable bag 38 is partially closed and is formed into a cup-like vessel. The closure of the disposable bag 38 is completed by removing the used bag 38 from the frame device 12 and tying off the opening thereof using drawstring 56. It is noted that throughout the operation of the device, fecal matter only touches the upper surface 48 and no fecal matter is in contact with the frame device 12. Similarly, the operator touches only the drawstring 56 which is mounted away from the canine activity by being mounted on lower surface 50. By maintaining strict separation, sanitary handling is achieved and device clean up is minimized. Further, an environmentally sound practice of using a biodegradable material for packaging canine waste is utilized.

Because many varying and different embodiments may be made within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive requirement of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
