Abstract

Abstract This invention consists of a mat which is designed to absorb a maximum amount of oil, keep the oil from seeping onto floors or work areas, be laid flat on floors or work areas, be unfolded during removal from containers, and folded to be repackaged in the original container. This is accomplished by a mat structure which internally incorporates mineral based absorbents, is pleated, and which has an underside composed of a material that is oil and abrasion resistant. Furthermore, the receipt/storage package is designed to keep the oil soaked mats from fouling areas external to this package. Such isolation of oil contaminated materials from other refuse constitutes sound environmental policy.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 190 words
An oil drip handling kit for containing oil drippings from automotive equipment, comprising a spreadable mat and a container for storage of said mat before use and for disposal of said mat after use, said mat is constructed of combinations of oil and petroleum absorbent materials, said materials are incorporated into said mat thus increasing said mats resistance to crushing, said mat has an underside sealing structure of a non-oil degradable material which is also abrasion resistant, flexible and oil impermeable, said mat is pleated so as to be adapted for folding and placement in said container, said container is provided with a liner, said liner extends around the entire interior of said container, said liner is non-oil degradable, abrasion resistant and oil impermeable, whereby in use the mat is withdrawn from said container and spread under automotive equipment so that said absorbent materials will receive any drippings, with said sealing structure preventing the oil drippings from flowing through the mat, when said mat is saturated, said mat is folded along said pleats and deposited into said container for disposal wherein said liner contains any oil drippings in said container.
