Abstract: A quick-opening closure device for sealed bags is described. The device can be opened and used by one hand, as the mouth of the bag is torn by the compression made by two fingers of a user by bending two juxtaposed sheets.

Abstract: Bows and crossbows having two limbs, of which at least one limb (4a, 4c or 36a) can elastically deform by deflection or simultaneous deflection and bending thanks to the synergy of the draw on the string (10) and on auxiliary cables (7) secured at the ends (4ad, 4cd or 36ad) of the limbs (4a, 4c or 36a) and to anchors (8, 41) on the heads of the riser (1) or the stock (33).

Abstract: An anti-tampering beverage container (1) made of plastic material such as PE, PET, PVC or the like intended to contain liquids and composed of a thin casing stretched and provided with a watertight closure cap (3), wherein it is made such to be with a containment volume that changes depending on the pressure difference between inner pressure (Pr) and external pressure (Pa), particularly the atmospheric one and it has a reference (Lo) for measuring the liquid level, so that with pressure changing inside the container changes of the liquid level are indicated due to the change of the containment volume so tampering actions being shown causing the container to be opened and so causing the inner pressure to change with respect to the original one under sealed condition.

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.

Abstract: A composite capsule and variants thereof for closing and sealing bottles and similar containers, which is essentially composed of two elements: a rigid capsule (2) and an extensible plastic diaphragm (2), integral therewith. Various processes for making the composite capsule and variants thereof. Said composite capsule and the variants thereof may be fitted in a single step on to bottles (1) and similar containers, by using conventional sealing apparatus. The capsule may also have an axial extension in the shape of a drinking-glass (30) whose specific function is supplemented by a tamperproof seal function.

Abstract: Various processes and relevant devices for causing polymer films, which are extensible with the help of the devices disclosed in Patent Application WO No. 98/32668 of Jan. 23, 1998 and in its applications, 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. P.S.

Abstract: A device for sealing container openings which uniformly applies a stretch plastic film onto the openings to be sealed. The device comprises a support, preferably flat-shaped, having at least one hole, on which is placed the stretch plastic film, the film is held taut and adherent to the support by means of gluing, magnetic force, pressure, or a counter-pattern. The device can bear a mark or a recognition message, as well as a warning or an advertisement and can also be used for temporary sealing of containers.
