Background-Field of Invention

This invention relates to a container device for the collection of pet waste and other noxous materials.

Background-Description of Prior Art

A primary application of this invention is the collection of dog waste which is a major problem in many parts of the world. For Example, it is estimated that in the United States there are more than 50 million dogs, that produce more than 5 thousand tons of waste per day. Most major municipalities have pet waste laws ("scooper laws") in an attempt to aleviate the some of this problem. Unfortunately, no product exists that allows pet owners to conveniently, effectively, and efficiently clean-up after their pet (e.g., their dog). All devices designed heretofore to address this problem are ineffective and inconvenient to use.

Collecting devices such as Almog U.S. Patent 5,000,500 (1991) require two hands to operate. Since the opening must be big enough to envelop the waste, the device will be too large to conveniently carry in a pocket. It is also not very functional if the waste is deposited in more than one mass or the stool is loose.

The scooping device of Wetzler U.S. Patent 3,767,247 (1973) has a tubular type of sleeve that requires the whole hand to operate. Since the collected waste will not slide

SUBSTITUTE SHEET

across the surface of the sleeve, collection requires that the device be periodically tilted to a vertical position to allow the waste to fall to the container. The length of the sleeve is used to trap the waste in the container but it also can cause collected waste to fall back out during the operation. The size of this device make it inconvenient to carry and expensive to make.

Objectives and Advantages

The objectives and advantages of my invention are:

1) It is a small, light-weight container device that will easily fit into clothing pockets, making it easy and convenient to carry.

2) It is a container device with the means of quickly and efficiently scooping or picking-up waste.

3) It is a container device capable of collecting almost any reasonable volume of waste.

Summary of the Invention

The present invention is a container device. It is comprised of a flexible container with a firm flexible collar around the opening. The collar is used to scoop the waste into the container. The collar is small and requires only two fingers to hold and operate it. The collar can open, close and manipulate the opening to the container. The device also has a protective skirt of flexible material that surrounds it and protects the user and the container from contamination. The skirt contains a closing means, such as a draw string or adhesive tape. After use, the skirt is pulled back over the container and closed. The device is folded and inserted in a packagingg tool. The packaging tool is of sufficient strength to hold the waste in place when scooping and assist in it's collection.

FIGS. 1 and 2. In a simple embodiment, as shown in FIGS

SUBSTITUTE SHEET

1 and 2, the container device consists of a container 20A and a collar 25A and a packaging tool 40A. The container 20A consists of two equal rectangular pieces of flexible material closed or sealed together at the edges on three sides 11A, 12A, 13A. It is open on the fourth side 14A to create a pocket into which waste is collected. The collar 25A is comprised of two flat rectangular strips of a firm, flexible material which are respectively bonded or affixed to opposite sides, at the edge of the open side 14A of the container 20A. The strips form a collar-like band at the opening of the container 20A through which the waste passes. The length of the collar 25A is parrallel and the width is perpendicular to the open end 14A of the container 20A. The length of the collar 25A is significantly greater than the width. The collar 25A has opposite ends with recessed finger areas 15A at each end for gripping. The length and width of the collar 25A are such that the recessed finger areas 15A can be gripped between a thumb and a finger and the collar 25A can be held and operated with one hand. The opposite sides may be bonded or affixed to the inside or outside of the container 20A. The collar 25A may be made of any firm flexible material capable of scooping up waste and flexible enough to repeatedly bend without cracking or breaking. The container 20A is folded around the collar 25A and inserted into the packaging tool 40A. The packaging tool 40A is a rigid chipboard sleeve which surrounds the container device and is open at the ends. It contains

SUBSTITUTE SHEET

recessed cut-out areas at the ends to facilitate the removing of the device.

FIGS. 3,4,and 5. In a preferred embodiment, the container device comprised of a container 20, a collar 25, a skirt 30 _r a closing means 35 and a packaging tool 40. In this preferred embodiment, as shown in FIGS. 3,4, and 5, the container device is constructed from two rectangular sheets of flexible material, closed or sealed ^" together on three sides 16,17,18 and open on the fourth side 19. The material is folded part way inside out to form a container 20 and a outer skirt 30. A collar 25 is constructed from a single strip of a firm flexible material which is folded in half to form two elongated sides. It is connected at the ends and is bonded to the material at the fold to form the opening to the container. The collar 25 transverses the opening to the container 20 and forms a collar-like band through which waste passes into the container 20. The length of the collar 25 is parallel and the width is perpendicular to the opening to the container 20. The collar 25 has opposite ends with recessed areas 15 for gripping. The length and width of the collar 25 are such that the opposite ends can be gripped between a thumb and finger of the users hand. The collar 25 is bonded or affixed in the vertical center and below the horizontal center of the material (away from the open end). This placement causes the skirt 30 to be longer than the container 20. A draw-string closing means 35 is added to the end of the open side 19 of the material.

SUBSTITUTE SHEET

In this embodiment, the material is wider than the collar 25. This allows space between the outer edges of the collar 25 and the sealed edges 16,18 of the material for the user to insert his hand and increases the load capacity of the container. The material is folded around the collar 30 and inserted into the packaging tool 40. The packaging tool 40 is an rigid chipboard sleeve which surrounds the device and is open at the ends. It contains recessed cut-out areas at the ends to make it easier to remove the device.

FIGS. 7 and 8. These figures show additional features which may be incorporated in the collar of the container device. The two elongated sides that form the collar will at times have a tendancy to bend togeather instead of away from each other when inward pressure is applied to the ends of the collar. This will necessitate separating the sides slightly before applying inward pressure. To facilitate this process the collar may incorporate a depression 22 (Fig. 7) or a protrusion 22 (Fig. 8). Either of these configurations will offset the edges of the collar and make it easier for the user to grip and separate the sides.

There are a variety of ways to manufacture this invention. It may be made of a wide variety of materials (e.g., paper, plastic, latex, elastomeric materials, etc.). It may be constructed from a single piece of marterial which is folded and or connected on three sides and open on the fourth side. It may also be constructed from two separate

SUBSTITUTE SHE

pieces of material which are connected on three sides and open on the fourth. The collar 25 may be affixed to the inside or the outside of the material. The material may be wider than, narrower than or the same width as the collar 25. The material may be bonded or affixed to the collar 25 flat or gathered. The material may be gusseted. The collar 25 may be affixed before or after the material has been folded to form the container 20 and the skirt 30, when both are constructed from the same material. The collar 25 may be made from a single piece of material which is folded and which may or may not be connected at its open ends or two seperate pieces which are generally affixed adjacent to each other" and which may or may not be connected at the ends. The collar 25 may incorporate a variety of designs to make grasping and using easier (e.g., recesses, protrusions and depressions, etc.). The collar 25 may be made from any number of materials that will function as described (e.g., chipboard, plastic, latex, metal, elastomeric materials, etc.). This invention may be constructed with or with out a outer skirt 30. The skirt 30 may be constructed from the same material as the container 20 or from a separate material. The skirt 30 may be constructed to be shorter, longer, or the same size as the container 20. This invention may or may not contain a closing means 35. The closing means 35 may be any of a wide variety of means (e.g., draw-string, draw-tape, adhesive, wire tie, etc.). The packaging tool 40 may be any one of

SUBSTITUTESHEET

many types of packaging means that will function as described (e.g., sleeve, box, wrapper, etc.). It may be constructed from any of a variety of materials (plastic, chipboard, elastomeric materials, etc.). The container device may only contain a tool of sufficient strength to stop the movement of waste without having packaging capability. The packaging and the scoop assist tool may be seperate items. The invention and all the parts may be constructed in a variety of sizes.

These examples illustrate some of the varying embodiments of this invention. From this description, a number of advantages of the present container device become evident:

1) The collar makes the device able to be made small, light-weight, and easy to carry.

2) The collar allows the user to quickly open, close and manipulate the opening of the container to facilitate collection.

3) The collar allows the user to collect the waste without actually touching it.

4) The skirt effectively protects the user and the outside of the container from accidental comtamination when in use.

5) The packaging tool provides an effective means to stop or compensate for the movement of the waste.

6) The draw-tape or draw-string closure provides a quick, effective way to enclose the waste in the container and transport it for disposal.
