Abstract
Abstract A laundry sling bag and roll about cart therefor, the cart having a front and top open frame with upstanding tabs for holding the bag therein in a top open position for easy loading and for permitting vertically forward power liftoff of the loaded bag from the cart, the bag having two straps to receive the power liftoff conveyor and a cart retaining device being employed to hold the cart down during the power liftoff, the bag being tapered from a large top opening to a smaller but contoured bottom opening and having adjacent bottom flaps formed from one bag half to close the open bottom and overlap with a relieved opposite bag half, whereupon quick release of the flaps is effective to dump the articles of laundry therein without binding or jamming and into a small loading opening in an underlying washer. In industrial or institutional laundries, it is common to segregate the dirty or soiled articles or goods in sling bags according to the specific types of article or color. For example, different type hospital goods might include uniforms, operating garments, patient garments, bed sheets, etc., where all like goods would be sorted into separate sling bags each of sufficient size to hold maybe 100 pounds of goods. The bags with like goods then can be accumulated and as required dumped into large industrial washers of maybe 400 pound capacity for laundering. By having all like type goods together, the proper washing temperature or washing solution can be used.
