Abstract
An article packaging device for packaging articles within a tubular sheet. The article to be packaged is inserted into and enclosed within a length of tubular sheet, and separated from the remaining length of tubular sheet and the device to form the closed individually packaged article. The packaging device is designed to be portable, convenient, lightweight and easily maintained. A thermoplastic, vapor-impermeable tubular sheet having adhesive on one surface can provide an airtight seal that is especially effective when the device is used to package waste-containing disposable adsorbent articles, such as soiled diapers, for disposal. An apparatus for forming the tubular sheet into a layered pack of pleats having an adhesive material positioned on at least one surface.

10. A method for manually forming a packaged article, comprising the steps of:
-
providing a packaging device including an inlet end, an outlet end, a passageway and a tubular sheet having a leading portion;
dispensing the leading portion into the passageway, gathering and closing the leading portion to form a receiving pouch within the passageway, inserting an article to be packaged into the receiving pouch through the inlet end, then in any sequence, gathering the trailing portion behind the article, thereby forming an individually packaged article, closing the gathered trailing portion, and separating the packaged article from the tubular sheet at the closed gathered trailing portion.

19. An apparatus for forming a pleated layered pack of a tubular sheet with an outer surface, and adhesive on a tubular sheet inner surface, the apparatus comprising:
-
a central mandrel having a mandrel base end, and a central mandrel axis, a plunger capable of movement along the central mandrel axis between a forward position and a base position, the plunger having a tubular sheet receiving end, a plunger forward end, a plunger base end, the forward end having an outer ring having a diameter, the outer ring conformed to engage the outer surface of the tubular sheet when the plunger moves from a forward position toward a base position, whereby the tubular sheet is engaged by the outer ring and pulled toward the base position and formed into a pleat, a reciprocating means having a connector affixed to the plunger, for reciprocating the plunger along the axis of the central mandrel between the forward position and the base position, and a pleat retaining means to restrain movement of a pleat, whereby the outer ring does not engage the tubular sheet when the plunger moves from the back position to the forward position.
