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.
