ABSTRACT:
A collapsible apparatus (10) recovers and dispenses packaging material. The collapsible apparatus (10) includes a receptacle (20) that is permeable to air. A disc (30) defines a lower end of the receptacle (20). A collection tube (36) is slideably received in a hole (34) of the disc (30) and has an inlet (38) outside the receptacle (20) and an outlet (40) inside the receptacle (20). A fan (60) is mounted to the disc (30) and communicated with the collection tube (36) to form a vacuum in the collection tube (36). The vacuum pulls the packaging material through the collection tube (36) and deposits the packaging material in the receptacle (20). A discharge valve (81) is a scissors valve that extends through the disc (30) for discharging packaging material from the receptacle (20). The receptacle (20) is collapsible and the collection tube (36) is positionable parallel a surface (32) of the disc (30) while the disc (30) carries the fan (60), the collection tube (36) and the discharge valve (81) to enhance compactibility.
