Abstract: An apparatus for making a fracture cut between the cup and the safety ring in plastic caps, which comprises rotary elements provided with at least one mandrel that can be arranged inside the cup and is suitable to produce the rolling, about its own axis of symmetry, of the side wall of the cup along the cutting edge of a blade for making the cut, the blade being associated with an inlet path portion adapted to axially offset the cup with respect to the rotation axis of the mandrel by clamping the side wall against the mandrel; the apparatus also comprises elements for recentering the cup with respect to the rotation axis.

Abstract: An indented portion under the opening ring in a can with a ring pull up and open mechanism to ease the opening process of cans. Option of advertising, lotteries and other marketing methods using the indentation to house such marketing literature.

Abstract: A tamper indicating closure comprising a base wall and a peripheral skirt having an internal thread adapted to engage the threads of a container wherein a tamper indicating band is provided on the skirt by a plurality of circumferentially spaced bridges. The band includes portions adapted to engage an annular bead on the container. The bridges are formed by using a primary knife having an interrupted cutting edge to produce a circumferential score in the side wall of the closure leaving spaced connectors or bridges followed by using a secondary knife having a continuous cutting edge to provide a continuous external score line and an accurately dimensional radial thickness of the bridges. In a preferred method and apparatus, the closures engage the successive primary and secondary knives and are moved such that the closures roll relative to the knives.

Abstract: A method and apparatus for scoring plastic tamper indicating closures to provide the tamper indicating band that is connected to the closure by bridges formed by scoring. The scoring is achieved by successively moving a rotating closure past a stationary primary knife blade having an arcuate concave interrupted cutting edge to form the bridges and then past a secondary knife blade having an arcuate concave uninterrupted cutting edge to accurately dimension the bridges.

Abstract: A fast feeder unit for an automatic machine for machining the cylindrical surface of bottle closure caps, including a feeder carousel, which is provided with devices for supporting and rotationally actuating it coaxially and in step with the carousel of the machine and whereon a plurality of axially slidable stems are mounted; the stems direct, towards the chucks of the machine, respective half-shells for supporting the caps and are connected to respective axial translatory motion devices adapted to move the half-shells from a position that is spaced from the chucks and co-planar to the openings of a fixed guide for feeding the caps to be machined and of a fixed guide for removing the machined caps, to a position for fitting a cap on the chuck and a position for removing the cap from the chuck.

Abstract: A method and apparatus for vertically scoring a tamper-indicating plastic closure includes a rotatably-driven carousel which includes mandrel assemblies at the periphery thereof. Each mandrel assembly includes a rotatable mandrel on which a respective closure is positioned in operative association, so that the mandrel and closure are moved relative to an associated scoring mechanism. The scoring mechanism includes at least one, and preferably a plurality, of rotatably driven scoring blades, with each blade arranged to engage and cut the pilfer band of a respective closure. Significantly, the system can be operated so as to closely approximate the preferred radial movement of the blade with respect to the closure, thus minimizing "digging" of the scoring blade into the plastic of the closure.

Abstract: A rotary slitter for container closures of varying sizes is disclosed. The embodiments include swivel housings to permit rapid changing of internal tools, and a rectilinear knife blade which eliminates adjustment problems normally occurring with curved knife blades.

Abstract: A method and apparatus for manufacturing a plastic closure particularly to facilitate orientation of the closure so that a manufacturing process, such as vertical scoring, can be effected at one of at least one predetermined portion of the closure. Such orientation is achieved by the provision of an orientation mandrel on to which the closure is moved. The closure is initially rotated relative to the orientation mandrel, with a stop mechanism of the mandrel thereafter engaging the closure and stopping such relative rotation. The stop mechanism of the mandrel is configured in a predetermined orientation with respect to an associated component of the apparatus, which in the illustrated embodiment comprises a vertical scoring mechanism. By this manufacturing technique, a closure having a tamper-indicating pilfer band can be scored and cut at a particular portion of the band, such as between container-engaging projections of the pilfer band.

Abstract: A gasketed mounting cup for an aerosol container having at least one annular sealing bead of gasket material in the channel portion of the mounting cup and method for making same.

Abstract: A container system for beer formed of a bottle body, a cap and sealing gasket formed of a blend of butyl rubber and one or more thermoplastic polymers. Preferably, the butyl rubber is present in an amount of from about 20 to about 60% by weight of the composition and the one or more thermoplastic polymers are present in an amount from about 40% to about 80% by weight of the composition. The system provides good sealing properties and prevents oxygen, and chlorinated substances such as chlorinated phenols or anisoles, that may be present in the packaging, from entering the bottle.

Abstract: A package formed of a wooden crate or pallet impregnated with a chlorinated phenol and/or anisole wood preservative, one or more bottles containing a potable material, such as beer, a cap on each bottle and a sealing gasket between the bottle and the cap. The gasket is formed of butyl rubber (20 to 80% by weight) and one or more thermoplastic polymers, preferably polyethylene (40 to 60% by weight).

Abstract: A method of forming either a metal or plastic pilferproof closure is disclosed. The closure has an end wall and an annular sidewall depending therefrom. For a metal closure, an annular ring is rolled in the sidewall so that it protrudes outwardly therefrom. The sidewall is scored adjacent to the annular ring to form a plurality of fracturable bridges which divide the sidewall into upper and lower portions. The annular ring is then compressed so as to form an annular bead which at least partially covers the bridges. The upper portion is susceptible to being deformed about the threaded neck of a container while the lower portion is adapted to be at least partially turned inward and into engagement with an annular shoulder formed on the container below its threaded neck. The annular bead serves to protect the fingers of a person who is removing the closure from coming in contact with the sharp edges of the broken bridges.
