The present invention relates to the field of equipment and methods for sanitary handling and disposal of biological wastes, and more particularly to equipment and methods for the sanitary handling and disposal of pet wastes.
A perennial problem facing pet owners is the sanitary handling and disposal of their pets' excrement. Public health regulations now universally require pet owners to thoroughly clean up and safely dispose of their animals' droppings, but the methods commonly employed are often extremely unsanitary. Even when disposal bags are used to collect and store the waste, the manual handling of such bags exposes the pet owner, as well as those they come into contact with, to biological hazards. Moreover, such pet waste disposal bags are typically mixed with household refuse for disposal without any treatment of their pathogen content whatsoever, thereby endangering public health.
Consequently, there is a great unfulfilled need for a standardized sanitary procedure for handling and disposing of pet waste and for a complete kit to implement that procedure. Providing such a kit and the method of its use is the principal objective of the present invention.
The present invention is directed to the following objectives:
Therefore, the pet waste disposal kit of the present invention includes the following items:
The kit is employed using the following method:
Alternately, the disinfecting-deodorizing mixture can be kept in a separate container and added to the waste collection bag after the pet waste and the gloves have been inserted therein. Another alternative is to have the disinfecting-deodorizing mixture constitute a coating on the interior of the waste collection bags.
Since high alkalinity (pH>11) and low moisture content are known to be effective in inhibiting bacterial growth, the disinfecting-deodorizing mixture contains one or more highly alkaline compounds, such as lime (calcium hydroxide, also known as hydrated lime). Lime can create pH levels greater than 12, which is sufficient to destroy the cell membranes of most pathogens. The high alkalinity of compounds such as lime also repels insects from infesting the treated waste. Lime also produces free calcium ions, which are effective in destroying odorous sulfur compounds. To reduce the moisture content of the treated waste, the disinfecting-deodorizing mixture also contains a desiccant, such as silica, activated charcoal or calcium chloride. The third component of the mixture is a deodorizer, such as baking soda (sodium bicarbonate).
The foregoing summarizes the general design features of the present invention. In the following sections, specific embodiments of the present invention will be described in some detail. These specific embodiments are intended to demonstrate the feasibility of implementing the present invention in accordance with the general design features discussed above. Therefore, the detailed descriptions of these embodiments are offered for illustrative and exemplary purposes only, and they are not intended to limit the scope either of the foregoing summary description or of the claims which follow.
As illustrated in
The supplies stored in the supplies compartment comprise: (1) a supply of lightweight, impermeable, biodegradable plastic gloves 17, (2) a supply of sealable waste collection bags 18 made of lightweight, impermeable, biodegradable plastic, with the interior of the bags coated with a disinfecting-deodorizing mixture 19, and (3) a supply of a liquid hand sanitizer 20.
The disinfecting-deodorizing mixture 19 comprises three components: a disinfectant, a desiccant and a deodorizer. In the preferred embodiment 10, the disinfectant is lime, the desiccant is silica, and the deodorizer is baking soda. The preferred composition by weight is approximately 50% lime, 25% silica and 25% baking soda.
The kit is employed by the pet handler first removing a pair of gloves 17 from the kit bag 10 and wearing them on his/her hands. A waste collection bag 18 is then removed from the kit bag 10 and opened. The pet waste is then picked up with the gloved hand(s) and put into the opened waste collection bag 18. Next the pet handler removes the gloves 17 and puts them into the waste collection bag 18. Then the waste collection bag 18 is sealed, and the sealed waste collection bag 21, containing the soiled gloves 17 and the pet waste, is shaken to coat the waste and gloves with the disinfecting-deodorizing mixture 19. Finally, the sealed waste collection bag 21 is put into the disposal compartment 16 of the kit bag 11, and the pet handler applies the hand sanitizer to disinfect his/her hands.
After following this procedure, the pet handler can now return home and safely dispose of the sealed waste collection bag 21 with his/her regular household waste, since the pet waste and soiled gloves 17 have been disinfected and deodorized, and since the waste collection bag 21 and all of its contents are biodegradable.
Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that many additions, modifications and substitutions are possible, without departing from the scope and spirit of the present invention as defined by the accompanying claims.
