摘要:
An apparatus for removing extensible plastic elastomer seals from the openings of bottles or other glass containers, which utilizes the aerodynamic pressure drop in a compressed air jet due to the constriction of its stream, caused either by the incidence of the jet on the edge of the openings of said bottles or containers or by the presence of an appropriately convex surface before of the seal. .' -22 -
摘要:
A combination of an apparatus for applying seals on the opening of bottles or similar containers, and a tape of sealing plastic material comprising: at least one applicator head (50), with at least a cavity, or a notch (51) whose shape is complementary to the opening (21) of the bottle (15) to be sealed; means for feeding the tape (16) between said cavity (51) and the opening (21) of a bottle; means for relative motion along the axes of the notch (51) or opening (21) of the applicator head (50) and of the bottle (15), in the two directions wherein the notch is fitted closely on the opening (21) and the applicator head (50) is displaced from said opening (21); means for feeding a succession of bottles (15) and for positioning them one after the other with their opening (21) being coaxial to the notch (51) of the operating head (50) ; the head having at least one face (150) with the opening (51) and being movable along the axis of said cavity (51); the tape (1,16) being unwound from a coil (52) and wound on a second coil (53); said operating head being positioned laterally staggered with respect to the axis connecting the axes of the two coils (52,53).
摘要:
A combination of an apparatus for unsealing a bottle or similar container having a seal formed by a film of extensible plastic material adhering on a certain part of the outer axial wall of the bottle end surrounding the opening (21).The apparatus comprises: an operating head (60), having a cavity (61) whose shape is complementary to that of the outer wall of the bottle (62), in the zone surrounding the mouth (63) of said container (62), said cavity (61) being arranged to receive said zone of said container (62), translation means (66), arranged to set the operating head (60) in a translatory motion, vertical to said container (62); suction means, connected to said cavity (61), in said operating head (60), near said mouth (63) of said container (62), and arranged to remove said seal means from said mouth (63) of said container (62); separating means (67), placed inside said cavity (61) of said operating head (60) and arranged to partially remove said seal means (64) from said outer wall of said container (62), separating the edge (68) of said seal means (64) and lifting it up.

摘要:
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.
摘要:
An apparatus for repeatedly applying seals on the opening of bottles or similar containers comprising: at least one applicator head (2,3), having a cavity, or a notch (4) whose shape is complementary to the opening (21) of the bottle (15) ; the operating head comprises at least two rigid members (2,3) being movable relatively to each other for clamping a segment of tape (1,16) between them whereas said members (2,3) have at least one trough hole (4) having a diameter longer than that of the edges of the openings (21) to be sealed; means for feeding the tape (1,16) between said rigid members (2,3); means for relative motion along the axes of the notch (4) or opening (21) of the applicator head (2,3) and of the bottle or container (15), in the two directions wherein the notch is fitted closely on the opening zone (21) and the applicator head (2,3) is displaced from said opening (21); means for feeding and for positioning a succession of bottles (15), one after the other, with their opening (21) facing the notch (4) of the operating head (2,3); said gripping members (2,3) being slidably movable along guide means (7) and guides (8), in such a way that the two gripping member (2) firstly clamp the tape and then execute a common displacement relative to the bottle (15) for drawing on its opening the tape (1,16).
