A. Impermeable sheet.
The base material for the invention is a sheet of impermeable material, similar to the average plastic grocery bag or trash bag, strong enough to contain the animal waste without being damaged. While impermeability is not imperative, and there are many materials capable of performing adequately, it is this inventors opinion that a leak proof barrier is preferable for containment and disposal with regard to toxicity.
B. Draw strings.
The draw strings are the primary element of the invention. When tugged against each other the sheet assumes the shape and function of a bag to contain the contents securely. How the strings are incorporated is less relevant than the result of enclosing the waste for proper disposal. While many manner of threading was explored, the end result is simply to close the package.
C. Folds to form string pockets.
The initial material is cut in such a way as to allow flaps to be folded over the draw strings (
D. Sealed pocket folds.
The seals to form the pockets are achievable in a number of ways. There are glues and processes a plenty to stick materials to materials. What manner used to constrain the material is less relevant than the function that the guide performs.
E. Draw string anchor points.
This inventor experimented with many ways to insert the draw strings. There were loops and double loops, tied, glued, crossed, and woven. It was the decision of this inventor to use the manner presented in figure one, but how the string is incorporated into the design is less relevant than its function of closing the package.
G. Flap.
H. Area of bond or seal.
J. Fold line.
