摘要:
The cap (1') has a shell (2) and a multilayer joint (3) with a metal layer forming a barrier against gas diffusion. A malleable support layer provides, adjacent set of layers, a malleable global mechanical behavior permitting, in association with a resilient layer, the joint to be subjected to deformation imposed by shaping the joint without formation of folds. An external layer in plastic material has an external surface to be indented under an axial compression effect of the cap and the joint against a neck such that the external surface mates with a widemouthed surface of the neck. The joint is free from a layer in a cellulosic material or in paper e.g. kraft paper. Independent claims are also included for the following: (1) a method for manufacturing a sealing cap (2) a method for capping a neck of a bottle.

The seal (1, 1',1''), which is made of a multilayered material (2), is used as a capsule for sealing a bottle of wine and comprises a layer C which can be subjected to resilient axial compression, and a layer B forming a barrier to oxygen. In said seal, layer B forms or comprises a deposit of organic material. The seal (1, 1', 1'') comprises a layer S forming a support for layer B, wherein said support S is or not in contact with layer C such that it is possible to have a structure comprising either a series of layers C, B and S, said structure being represented symbolically by C/ B/ S in the case of adjacent layers C, B and S, wherein layer S enters into contact with wine, or a series of layers C, S and B, said structure being represented symbolically by C/ S/ B in the case of adjacent layers C, S and B, wherein layer B enters into contact with wine. Advantages: possibility of forming screwed sealing capsules provided with a large variety of seals adapted to the specific requirements of each type of wine, in order to replace tradition corks.

The invention relates to a closure (1), embodied to cooperate with a neck (5) of a container, said neck (5), having a wide mouth (50) on the upper part thereof and an external thread (52) and a tapering piece (53) on the lateral wall, for sealing said closure (1) which comprises a) an external body (2), typically comprising an external head and an external skirt, b) an insert (3), typically made from plastic, said insert (3) enclosed within said body (2) and fixed to said body (2), comprising an internal head (30) and an internal skirt (31), provided with an internal thread (33), for cooperation with the external thread (52) of said neck (5) and c) a sealing joint (4), typically forming an inset piece, fixed to the insert. Said joint (4) comprises a central piece (40) and a peripheral or border piece (41), characterised in that said insert (3) comprises a radial compression means (6), for said sealing joint (4) against the neck (5), such that when said bottle closure (1) is screwed to the neck (5), said border (41) is compressed radially between said insert (3) and said neck (5). The above has advantageous sealing and the opening torque for said closure (1) is little dependent on the temperature and axial position of the closure (1) with relation to the neck (5).

The method comprises a) an extrusion stage wherein a extruded tube made of a thermoplastic material (20) is formed by extrusion with the aid of an extrusion die having a diameter D0, a slit width E0 and a section S0; b) a stage wherein the extruded tube (20) is radially expanded in order to form a radially expanded tube (23) having a diameter D2, a thickness E2 and corresponding section of area S1; c) a truncating stage wherein the expanded tube (23) is broken down into tube portions (24); d) a stage in which the tube portions (24) are formed in such a way that a heat-shrinkable cap or capsule is obtained (1) and in which an axial drawing stage is incorporated, between extrusion stage a) and expansion stage b), at the output of the extrusion die (31), in order to obtain an axially drawn tube (22) having a diameter D1 which is typically smaller than D0 and D2, and a thickness El which is typically lower than E0, such that S0/S1 typically ranges between 2 and 10. The advantages of the invention are as follows: it is possible to obtain capsules (1, lb, lc) or caps (la) which are economic, easily heat-shrinkable and which have a stable axial dimension, thereby avoiding any axial distortion, i.e. any axial distortion of said impression (13).
摘要:
The invention concerns a method comprising: a) providing sheet or format metal; b) swaging said metal by means of a swaging lubricant, so as to form a swaged blank (1); c) degreasing said swaged blank (1), so as to typically remove the remains of the swaging lubricant, to form a degreased blank (2) capable of being lacquer coated; d) lacquer coating said degreased blank (2), said resulting lacquer coated blank (3) being then optionally decorated; e) an optional finishing step. The method is characterized in that during the degreasing at step c), said swaged blank (1) is subjected to an energetic radiation emission treatment of selected intensity and duration to eliminate or decompose said remains of lubricant, said treatment being wholly carried out at a metal temperature less than 150 DEG C, and for a duration typically less than 1 second, so as to obtain, following said treatment, a surface tension not less than 34 dynes/cm. The invention also concerns a device for implementing said method. The invention provides the advantage that the low temperature degreasing preserves the mechanical properties of the metal of the swaged blank (1).
