Abstract: An envelope is disclosed which includes a front panel and a rear panel. Each of the front and rear panels are made from an outer layer and an inner cushioning layer formed from a plastic air-cellular material. The front panel is connected to the rear panel along a bottom edge and a pair of side edges. A folding flap is connected to a top edge of the rear panel. The flap includes a number of separable portions. Each of the separable portions has an adhesive layer on an adjacent surface thereof. The flap is movable between a closed position where a selected separable portion is adhered to the front panel, and an open position where the flap is separated from the selected separable portion. The flap may be repeatedly closed and opened by sequentially adhering and separating the separable portions in a proximal direction.

Abstract: A conveyor device for conveying a chain of air-filled packing pillows to a selected position includes a generally upstanding duct, a support for supporting the device on a surface, and a pump positioned adjacent to the surface for supplying air to the device. The duct has an air inlet end connected in fluid communication with the pump, an outlet end, and an entrance aperture positioned downstream from the pump and the air inlet end for receiving the chain of air-filled packing pillows. When the pump is activated and the chain of air-filled packing pillows is inserted through the entrance aperture, the chain of air-filled packing pillows is conveyed upwardly through the duct in a longitudinal direction relative to the chain, and directed to arrive at the selected position.
