Abstract
An apparatus for air and liquid-tight packing of objects for disposal, such as sanitary towels, disposable nappies, hypodermic needles and other hospital wastes comprises a pair of supply rolls of mutually adhesive foil strips. The side edge of the foil strips are urged towards each other to seal the respective side edges together while a transport system engages the side edges and moves the foil strips through the apparatus. A pressing system includes a pair of substantially flat elements, at least one of which is rotatable, which extend substantially over the width of the foil strips and guide the strips together capturing and sealing an object to be packed therebetween, and sealing the foil strips together across their width after passage of the object.

Apparatus for air and liquid-tight packing of objects, comprising:
- first and second supply rolls of mutually adhesive foil strips;
- adhering means for urging side edges of the foil strips toward each other;
- drive means engaging the foil strips for transporting both foil strips;
- and
- non-motorized pressing means for continuously urging the foil strips toward each other over substantially an entire width thereof after insertion of an object, for the mutual adherence of the strips, wherein the pressing means comprise a pair of substantially flat elements which extend over at least a substantial portion of the width of the foil strips and at least one of which pivots toward the other element, the flat elements forming an insertion funnel along an inner side of which the foil strips are guided and spring means connecting said flat elements to provide sole pressing force between said elements.
