Abstract: The subject matter relates to a pilferproof closure for a container in which the closure is threadedly engaged with the thread of the neck of the container and is of the type which includes a locking band at its lower end having its lower edge turned under a shoulder on the container neck, with the locking band being separated from the main body of the closure by a circumferential line of lancing and spaced bridges, with the bridges being the sole means of attachment of the band to the main body of the closure. The locking band is provided with several circumferentially spaced vertical weakening lines, preferably four equally spaced, which rupture on unscrewing of the closure to produce outwardly flared sectors in said locking band, whereby the entire closure, including the locking band, is completely removable from the container neck. The bridges do not fracture for the most part, but instead function to provide bend lines for the outwardly flared sectors.

Abstract: APPARATUS FOR SEQUENTIALLY EFFECTING REGISTERED JOINDER OF SHEETS OF MATERIAL. SHEET TRANSPORTING MEANS FOR SEQUENTIALLY MOVING SHEETS TO A JOINING STATION, REGISTRY MEANS FOR RAISING THE TRAILING END OF A LEADING SHEET AND ENGAGING THE LEADING END OF A TRAILING SHEET. FIRST SHEET CLAMPING MEANS DISPOSED REARWARDLY OF THE REGISTRY MEANS AND SECOND SHEET CLAMPING MEANS DISPOSED FORWARDLY OF THE REGISTRY MEANS. JOINING MEANS FOR ESTABLISHING THE JOINT WHILE THE SHEETS ARE CLAMPED IN REGISTERED POSITION AND CONTROL MEANS FOR COORDINATING OPERATION OF THE CLAMPING MEANS AND THE JOINING MEANS. THE REGISTRY MEANS HAS A VERTICALLY RECIPROCATING REGISTRY BAR PROVIDED WITH SHEET ENGAGING FACES. OPERATING MEANS CONNECTING THE CLAMPING MEANS WITH THE REGISTRY BAR TO ESTABLISH MOVEMENT OF THE REGISTRY BAR RESPONSIVE TO MOVEMENT OF THE CLAMPING MEANS. A METHOD OF EFFECTING REGISTERED JOINDER OF SHEETS OF MATERIAL. AUTOMATICALLY FEEDING A SHEET FORWARDLY INTO CONTACT WITH REGISTRY MEANS. SIMULTANEOUSLY RAISING THE TRAILING END OF A FORWARDLY DISPOSED SHEET AT THE REGISTRY MEANS. CLAMPING THE SHEETS IN REGISTERED POSITION AND SECURING FASTENING MEANS TO THE CLAMPED SHEETS. UNCLAMPING THE JOINED SHEETS AND MOVING THEM FORWARDLY TO A POSITION IN WHICH THE TRAILING SHEET BECOMES THE LEADING SHEET FOR THE NEXT CYCLE OF OPERATION.
