Abstract: A composite laminar tape for mass-sealing bottles or similar containers consists, according to the invention, of at least one extensible laminar tape, made of an extensible plastomeric film, which is possibly provided with closed lines for a predetermined separation of areas being meant to act as sealing membranes. The invention also relates to an apparatus for mass-sealing containers with said tape, and to an apparatus for mass-unsealing the containers sealed with said tape.

Abstract: A composite laminar tape (1) for mass-sealing bottles (15) or similar containers consists, according to the invention, of at least one extensible laminar tape (16), made of an extensible plastomeric film, which is possibly provided with closed lines for a predetermined separation of areas being meant to act as sealing membranes. The invention also relates to an apparatus for mass-sealing containers with said tape, and to an apparatus for mass-unsealing the containers sealed with said tape.

Abstract: A cap for the hygienic sealing of bottles for drinkable liquids, which in one embodiment includes a closed bottom cylindrical, i.e. cup-shaped, aluminum sleeve, an insert composed of a lower hollow cylindrical base, a truncated cone also having a hollow shape, and a tapered wall having two or more elongate and vertical apertures formed therein. Said cap is further characterized by a stretchable plastic membrane that is stretched to externally cover the truncated cone-shaped section of said insert as well as its top opening, by an elastic plastic ring for clamping said membrane against the insert, and by an additional plastic structure concentric with the sleeve that sealingly occupies at least its closed bottom and acts as a seal.

Abstract: An apparatus for removing extensible plastic elastomer seals from openings of bottles or other glass containers is provided. Aerodynamic pressure drop in a compressed air jet is used. Due to constriction of the air stream caused, either by the incidence of the net on the edge of the openings of said bottles or containers, or by the presence of an appropriate convex surface before of the seal, the containers are removed.

Abstract: Various processes and relevant devices for causing polymer films, which are extensible to adhere to the edges of openings of plastic or PET or even metal containers, by releasing electrostatic charges opposite in sign to those of containers and/or the polymer films to be applied thereto. The processes derive from a single general inventive concept.
