Abstract: A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.

Abstract: The metal packaging includes a tubular part (1) defining a longitudinal axis (1?), which tubular part (1) includes a one-piece annular structure (10) made up of one moulding (11) or of several mouldings (11) which are formed on a plane (13) running perpendicular to the longitudinal axis (1?) and on the circumference of the tubular part (1) to form an annular lower surface (12) against which a handling member is intended to rest.

Abstract: The present invention relates to an apparatus for processing a sealing lip of a metallic can, and a metallic can processed by the apparatus. The present invention provides an apparatus for processing a sealing lip of a metallic can comprising: a pressurization block which is lifted and lowered by a lifting means to elastically provide pressure downward; an interlocking means which moves downward step by step by the pressure of the pressurization block and has a coupling relation in which the means stops at stages in the level difference structure of a base so as to be held; and a lip processing member which presses the sealing lip to the inside and outside of a bottle neck of the metallic can while interlocking due to the movement of the interlocking means, and provides a metallic can wherein a notch groove is processed at a beading part by the apparatus for processing a sealing lip of a metallic can.

Abstract: An effective thread number in the thread section which is disposed on the mouth section of the bottle is formed to be 2.2. That is, the thread section is formed such that the thread section 13 should serve effectively in the mouth section such that an interval between a start position and an end position should be 2.0 to 2.5. In the bottle can member 11 which has such a thread section, an outer diameter of the thread section which is formed on the mouth section is 28 to 38 mm. Also, the thickness of the mouth section is 0.25 to 0.4 mm. The thread section which has the effective thread number 2.0 to 2.5 is formed by eight-thread per inch pitch. By doing this, it is possible to put the cap desirably.

Abstract: A threading turret assembly includes a plurality of threading heads. The threading heads comprise first and second threading rollers. The threading head is configured to impart a thread onto a metallic can such that a threaded cap may be screwed onto the can to seal an opening in the can. The turret assembly is configured to rotate such that the plurality of threading heads orbit the centerline of rotation about which the turret rotates. The turret is configured to impart a rotation onto the plurality of threading heads as the threading heads orbit the center of rotation.

Abstract: An embodiment of the present invention is a vessel forming station comprising a plurality of operation wheels, the plurality of operation wheels are configured in opposing facing pairs, a plurality of linear drives are interconnected with the plurality of operation wheels, the plurality of linear drives push opposing facing pairs of the plurality of operations to a closed position causing opposing facing pairs of the operation wheels to engage the vessel and perform operations on the vessel, the linear drives pull the plurality of operation wheels to an open position allowing the vessel to be indexed to other operation positions, and a conveyor system positioned between opposing facing pairs of the plurality of operation wheels engages the vessel and indexes the vessel through the plurality of operations.

Abstract: A method and apparatus for forming container ends includes tooling which forms dome members for can ends, which dome members include an open neck thereon. Thread lugs are formed as integral spaced apart shaped protrusions from the neck exterior. A system is also disclosed for forming quantities of a specific form of dome members, capable of later attachment to container bodies. A thin metal strip is fed through an array of progressive tooling to form blanks, from which such specific form of dome members are formed. The blanks are produced in the metal strip and connected thereto by multiple carrying strips which allow sufficient mobility of the blanks with respect to the strip to achieve precise alignment with the tooling at different stations in the progression. At the final station, completed dome members are separated from the remaining metal skeleton and moved rapidly out of the system, and the skeleton may be chopped up for recycling.

Abstract: An easy-open, reseable closure assembly for a beverage can (10) comprises a metal lid (12) and two threadedly connected molded plastic closure elements (40, 60) with engageable annular reseal surfaces (46, 76). The lid is scored (30) to define a circular tear panel (28) and a hinge (32). The spout element (40) is attached to the lid (12) with the bottom surface of the cap element (60) directly above and aligned with the periphery of the tear panel (28). Rotation of the cap element (60) by a user ruptures the tear panel and pivots the tear panel (28) downward about the hinge (32), providing a passage through the spout element (40) for pouring and driking. Initial rupture and rupture propagation of the tear panel (28) is controlled by the spacing of the cap element (60) from the tear panel (28) and their configurations. When the cap element (60) is replaced on the spout (40), reseal surfaces (46, 76) engage.

Abstract: An apparatus for threading a closure having cylindrical walls which includes securing the closure in a stationary nest, inserting a threading tool having indentions on the outside thereof into the interior of the closure, moving the closure into a ring having projecting threads on the inside thereof around the outside walls of said closure, moving the threading tool into contact with the interior portion of the closure upon which threads are to be formed, and moving the threading tool around the interior portion of the stationary closure in an orbital path to form threads in the closure without rotating the threading tool about the threading tool axis.
