Abstract: A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device comprises two opposing sealing elements between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first transverse seal of the tube. It further comprises two volume control elements. The forming device is characterized in that it is arranged to displace the first transverse seal off-center in relation a longitudinal axis of the first portion of the tube in a displacement direction essentially perpendicular to the first transverse seal to enable later shaping of a corresponding final package with a wall arranged with a predetermined angle of inclination in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.

Abstract: An opening arrangement includes a bottom piece disposed to be positioned on a packaging material and to define a pouring opening; a lid disposed, in a closed state, to seal the pouring opening; and a tamper evidence intended to be broken the first time the opening arrangement is opened and which is connected to a pull tab connected to the lid and to a fastening surface disposed to be connected to the packaging material. The fastening surface is disposed to extend over a fold line along which the packaging material is intended to be folded for forming a package. A package and a method of providing a package with an opening arrangement are also disclosed.

Abstract: A closure device comprising a plastic lid which is articulated to a skirt that is designed to surround a neck of a container. A majority of the surface of the lid is made up of an external convex surface that is provided with a concave recess which is disposed more or less opposite an area in which the lid is articulated to the skirt. One section of the lid can rest against a heel which is provided close to an upper edge of the skirt so as to lock the lid in a position in which the device is completely open.

Abstract: The present invention relates to an opening arrangement (10) comprising a bottom piece (11) which is arranged so as to be positioned on a packaging material (1) and to delimit a pouring opening, a lid (12) which is arranged so as, in closed position, to seal the pouring opening, tamper evidence (14) which is intended to be broken the first time the opening arrangement (10) is opened and which is connected to on the one hand a pull tab (13) connected to the lid (12) and on the other hand a fastening surface (15) which is arranged so as to be connected to the packaging material (1), the fastening surface (15) being arranged so as to extend over a fold line (1e) along which the packaging material (1) is intended to be folded for formation of a packaging. The present invention also relates to a packaging and a method of providing a packaging with an opening arrangement.

Abstract: The present invention relates to an opening arrangement (10) comprising a bottom piece (11) which is arranged so as to be positioned on a packaging material (1) and to delimit a pouring opening, a lid (12) which is hinged about a folding joint and arranged so as, in closed position, to seal the pouring opening, tamper evidence (14) which is on the one hand connected to a pull tab (13) connected to the lid (12) and on the other hand connected to the bottom piece (11) or arranged so as to be connected to the packaging material by means of a fastening surface (15), and which tamper evidence (14) is intended to be broken the first time the opening arrangement (10) is opened. That portion (13b) of the pull tab to which the tamper evidence (14) is connected, the tamper evidence (14) and that portion of the bottom piece (11) to which the tamper evidence (14) is connected or the fastening surface (15) which is intended to be connected to the packaging material (1) extend essentially along a common plane (16).

Abstract: The tamperproof closing device for a receptacle having a threaded collar comprises a screw cap (1) consisting of a bottom (8) and a cylindrical skirt (9) having inner threading for co-operation with the corresponding threading (5) on the collar (2) and extended by a tamperproof ring (13) which is attached by frangible means (20). The collar has a plurality of outer radial notches arranged at the base thereof. Said notches are circumferentially oriented and the ring comprises a plurality of inner radial reliefs (15) whose profile is complementary to that of the notches (7). The orientations and dimensions of the notches (7) and reliefs (15) are determined in such a way that the second items can pass onto the first items in the direction of screwing as a result of elastic deformation of the constitutive material and can prevent the same from occurring in the opposite direction. The reliefs (15) are formed on an annular lip (14) which is turned back and originates from the tamperproof ring (13).
