The invention relates to a stopper capsule, having an axial direction, including a shell, with a head, a skirt, and a joint, where a) the joint is a form joint, b) the form joint has b1) a resilient layer, a set of adjacent layers, b2.1) a barrier layer, b2.2) a malleable support layer with the function of providing the set of adjacent layers a global malleable property such that the joint can be shaped without creation of folds, b2.3) an outer layer having an outer surface which can be compressed by the axial compression resulting from stoppering such as to match the form of the mouth of the neck. The invention further relates to a method of production of the capsule and a method of stoppering.

Anti-filling device to be attached to the neck of a bottle to be closed by a sealing cap, including attachment means for attachment to the bottleneck, a chamber including a lower lip surrounding a lower orifice and confining a moveable part which forms a valve in conjunction with the lower lip, and an axial distribution duct. The device further includes a moveable axial rod, secured to the anti-filling device, the axial movement of which relative to the device is limited between a low position and a high position, and at least one stopper which is in engagement with the moveable axial rod such that, when the moveable axial rod is located in the low position, the stopper shuts an orifice which is arranged in the chamber. The low position is imposed by a projection attached to the cap, which comes into contact with the moveable axial rod when the cap is attached to the bottleneck.

The method comprises a) an extrusion stage wherein a extruded tube made of a thermoplastic material is formed by extrusion with the aid of an extrusion die having a diameter D, a slit width Eand a section S; b) a stage wherein the extruded tube is radially expanded in order to form a radially expanded tube having a diameter D, a thickness Eand corresponding section of area S; c) a truncating stage wherein the expanded tube is broken down into tube portions; d) a stage in which the tube portions are formed in such a way that a heat-shrinkable cap is obtained and in which an axial drawing stage is incorporated, between extrusion stage a) and expansion stage b), at the output of the extrusion die, in order to obtain an axially drawn tube having a diameter Dwhich is typically smaller than Dand D, and a thickness Ewhich is typically lower than E, such that S/Stypically ranges between 2 and 10. The advantages of the invention are as follows: it is possible to obtain caps which are economic, easily heat-shrinkable and which have a stable axial dimension, thereby avoiding any axial distortion, i.e. any axial distortion of the impression.

Method for the production of caps with a heat shrinkable skirt and caps obtained according to the method

A closure, embodied to cooperate with a neck of a container, the neck, having a wide mouth on the upper part thereof, an external thread and a tapering piece on the lateral wall, for sealing the closure which includes a) an external body having an external head and skirt, b) an insert, enclosed within the body and fixed thereto, including an internal head and skirt, provided with an internal thread, for cooperation with the external thread of the neck and c) a sealing joint, forming an inset piece, fixed to the insert. The joint has a central piece and a border piece. The insert includes a radial compression element, for the sealing joint against the neck, such that when the bottle closure is screwed to the neck, the border is compressed radially between the insert and the neck.

The screw capsule includes two parts, a) an insert with a so-called internal head and an internally-threaded skirt a metallic shell, including an external head and an external skirt, the capsule being typically provided with a sealing element, a tamper-protection element and a member for first opening, characterised in that the external skirt includes at least one piece, typically cylindrical, of height, diameter corresponding to the neck for sealing and at least one radially-expanded section, of height, within a circle of diameter D&#x3e;D, such as to form an annular radial cavity. The above offers the advantage that the expanded section particularly facilitates the manipulation of the capsule () and the rotation thereof with relation to the neck for opening/closing the container by unscrewing/screwing up the capsule on the neck.

Stopper capsules and method for production thereof

A functional insert including a body which is provided with at least one flexible flange on the outer surface thereof, for creating a tight connection with the neck, and a functional element. The functional insert is characterised in that: a) it includes an adhesive which is typically carried by the flange and is selected in such a way that it adheres to the neck of the recipient, and b) the adhesive is typically a permanent adhesive selected in terms of its consistency or viscosity such that it only squeezes out under stress. In this way, any axial displacement towards the top of the functional insert is prevented by fixing the body to the neck of the recipient by means of an adhesive contact region.

The cap () comprises a head and skirt and is characterised in that it comprises two assembled parts:

Composite sealing cap

The invention concerns a cap () comprising as assembly consisting of: a) a plastic insert () comprising a head () with closure means () and a threaded skirt (), and b) a metal wall. The invention is characterised in that: 1) said metal wall () covers all or part of the outer surface of said insert () and includes at least a metal skirt () for receiving said skirt () of said insert (); said metal skirt () includes an edge () crimped to said insert () so as to assemble together said metal wall () and said insert (); 3) said cap comprises means designed to provide weight and/or volume to the part of said cap located above said sealing closure means ().

Composite closure cap

A spill-proof pouring device for fixing inside the neck of a bottle includes a skirt sealing to the inside of the neck on its outer surface and having an internal channel. An upper flared portion of the skirt protrudes beyond the lip of the neck, and is formed of a flexible material. The flared portion joins the skirt at a point of union of reduced thickness to permit flexing action by the protruding portion.

Process for manufacturing a metal can with a threaded neck on which a removable head can be fitted, includes the steps of forming a can with a closed bottom end, a cylindrical wall and an open top end, forming a neck at the open top end, obtaining a ring with a spindle hole of known diameter and a threaded external surface, sleeve fitting the ring by driving the spindle hole over the neck, and plastically expanding the neck by an amount sufficient that its outer diameter exceeds the diameter of the spindle hole when unstressed.

Sealing cap for closing screw top receptacles includes a metal cap having inner and outer surfaces, a threaded insert formed of a plastic material disposed within the metal cap and rigidly fixed to the inner surface thereof, and a coating bonded to at least a portion of the inner surface of the metal cap. The coating contains plastic material in a divided state and is heat sealed to the insert.

Sealing metal cap with plastic insert

An overcap for a container including a head portion and a skirt portion, and a method for its production. The skirt portion has a metal wall and an opening area constructed and arranged to be broken during removal of the overcap. A sleeve of plastic material adheres to the metal wall over an area limited to the opening area.
