ABSTRACT:
A process and a device for holding a flexible plastic liner within a rigid or semi-rigid waste or storage container.
The device or apparatus includes a split or divided shaft 30 which is attached to a ratchet wheel 104, which is controlled by a worm gear 102. Worm gear 102 is capable of moving the ratchet wheel both forwards and backwards and holding the wheel stationary. The worm gear is attached to or is a formed part of the shaft 111 which is further attached to a key or handle 100, that when rotated, turns the shaft 111, the ratchet wheel 104, and the split or divided shaft 30. The worm gear 102, the shaft 111, and the ratchet wheel 104 are housed in a split housing with top part 98 and bottom part 99. The housing 98-99, contains an attachment strap holder 46 through which the attachment strap 44 passes, thereby, attaching the device to the attachment strap 44. The attachment strap 44 is further hooked over the top edge 110 of the container 108, thereby, attaching the device to the container. The process involves placing the flexible plastic liner 112 within the container 108, folding its top uppermost portion 114 over the container edge 110, inserting the folded over liner portion 114 into the split or divided shaft 30 and rotating shaft 30 until the liner portion 114 is securely tightened around the top portion of the container 108.
