  • Patent number: 7395643
    Abstract: A rigid pack for tobacco products comprises an outer wrapper (3) furnished with a container (4) presenting an open top (5), surmounted by a lid (6) hinged to the container (4) and rotatable between a position in which the open top (5) is exposed and a position, interacting with a frame (20) anchored to the open top (5), in which the open top is closed, the tobacco products being enveloped by an inner wrapper (19). The pack (1) presents four lateral faces (16, 17, 18) arranged in two parallel pairs, also a top end face (15) and a bottom end face (11) disposed transversely to the lateral faces (16, 17, 18), which define a front, a back and two flanks. At least one of the lateral faces (16, 17, 18) presents a deformation referable to at least one bend line (21), coinciding with a crease line (3) impressed previously on the blank from which the pack is fashioned, and obtained by subjecting the flank faces (18) to compression in such a way that the bend line (21) is forced into relief.

  • Patent number: 6939282
    Abstract: A re-sealable container closure label including a base label and a cover label, and a hook-and-loop fastener system and a tamper-evident tear strip is sandwiched therebetween. In a preferred embodiment, the base label is adhered to the front wall of a container, preferably a bag, adjacent an opening in the bag. A flap of the bag is folded downwardly over the opening and adheres to the front wall, the cover label, the two-part hook-and-loop fastener system and the tear strip. In an alternative embodiment, container closure label includes a hook-and-loop fastener system and a tear strip secured only to a base label. This alternative embodiment label is adhered to the front wall of a bag as in the preferred embodiment, except that the flap is adhered directly over the fastener system and tear strip. To open a bag sealed with the re-sealable container closure label, a user pulls the tear strip, which permits the flap to open and form a pour opening.

  • Patent number: 6112505
    Abstract: Rigid packets of the type with a hinged lid are fashioned from diecut blanks presenting a central longitudinal portion flanked by two lateral portions, each consisting in a series of longitudinally disposed flaps. The method of manufacture involves directing the blanks singly and in succession between a pair of contrarotating rollers with dies shaped and positioned to engage each lateral portion; the dies are designed to modify a pair of adjoining flaps on each side, which ultimately will be bent through a right angle to form an internal layer of the relative flank face of the packet, by producing at least one bend in one flap at an end adjacent to the other flap, and forming a projection on the longer flap which in the finished packet will be breasted permanently in contact with an inner reinforcing frame.

  • Patent number: 5983600
    Abstract: A label (e.g., a revenue stamp) for the application to a closed and filled hinged-lid packet for cigarettes or the like has a first part provided with an elongated weakened portion which is to overlie the abutting sloping edges of one lateral wall of the main section and the corresponding lateral panel of the lid in the closed position of the lid, and a second part overlying portions of the rear wall of the main section and of the rear panel of the lid at opposite sides of the elongated transversely extending hinge which pivotally connects the rear panel to the rear wall. The weakened portion is formed by a perforating, scoring, piercing, material removing or other suitable implement which is adjustably mounted on a support adjacent to an arcuate path for a succession of labels at the periphery of a rotary conveyor. One side of each label is coated with an adhesive subsequent to weakening and preparatory to attachment to a hinged-lid packet.

  • Patent number: 5727367
    Abstract: Packaging material, particularly for forming blanks for hinged lid packets, is delivered to a packaging machine in web form and at least one creasing or shaping operation is performed (44; 112) on the web (2) prior to severing individual blanks (50) from the web. Folding or wrapping of a blank around an article to be packed in the machine is monitored and the creasing or shaping operation varied to optimise machine performance: for example, an adjustable creasing tool can be adjusted to compensate for tool wear. Individual blanks are inspected for longitudinal curl, usually caused by the web having been wound on a reel, and where necessary a correction is applied during feeding of the web, e.g. by adjusting the angle of wrap of the web around a decurling roller (38; 108).

  • Patent number: 5316811
    Abstract: In the production of packs, especially hinge-lid packs, from rigid packaging material (thin cardboard), hitherto individual blanks have been supplied in stacks and introduced into the packaging machine in succession. To make the handling of the blanks easier and to increase the storage capacity, the blanks (23) are now connected to one another via residual connections (25) into a continuous web of material (24) wound as a reel (30). Within the packaging machine, the blanks are severed from the web of material (23) in succession, specifically as a result of the elimination of the residual connections, preferably by being torn off. The residual connections (25) are formed in a region of the blanks (23) or in the region of folding tabs of the latter which, in the finished pack (hinge-lid pack), are concealed by other folding tabs, that is to say are on the inside.

  • Patent number: 5113638
    Abstract: In the production of packs made of (thin) cardboard such as cigarette packs, complex folding processes may cause problems when blank portions are moved to the proper pack position, especially when blank portions are "too long" for the folding process. To remove this problem, the respective blank portion is, during the folding process, temporarily deformed in a way which shortens its effective length, i.e. curved in an arched manner. In the production of hinge lid packs having a collar (11) attached to a front wall (12) thereof in a single piece, this blank portion is, while being folded from an upright to a horizontal position, temporarily curved by a folding lever (58) applying pressure until the blank portion reaches the horizontal folding position.

  • Patent number: 4938005
    Abstract: Hinge-lid packs, especially for cigarettes, are equipped with a collar which extends in the region of the front wall and side walls of a pack part of the hinge-lid pack and which projects from this. The collar is formed from a collar blank severed from a material web of thin cardboard, specifically by being laid onto the pack content, especially a cigarette block. On high-performance packaging machines, the hinge-lid packs are produced in two production tracks running next to one another. Two collar blanks (10, 11, 12) therefore have to be fed simultaneously to the cigarette blocks (15, 16) to be packaged simultaneously. For reasons of space, the collar blanks (10, etc.) are severed from a single material web (13), then grouped next to one another in pairs and finally transported into the region of a transfer station (14) by means of a transversely directed feed conveyor (41).
