Abstract: The invention relates to an inert gas flow which is directed through a channel. The channel includes walls (19,21) which limit the flow. A container having a charging inlet is fed through a recess (10) which is arranged in the first wall (21) adjacent to the flow. According to the invention, the channel includes limiting structures for the flow which are arranged in the area opposite the recess and the first wall can be displaced in a parallel manner in relation to the limiting structures. The channel, together with the container, forms a closed inert gas rinsing chamber.

Abstract: A can includes a membrane seal (5), which has a continuous bead (3) in the can casing (1), the bead facing inwards in the vicinity of the can edge (8), preferably at a distance of between 1 and 10 mm from the edge. The bead is connected in a sealed manner to a sealing membrane (5), for example a foil membrane, in particular a tear-open foil. The upper part (3a) of the bead facing the can edge and the lower part (3b) of the bead facing the interior of the can, viewed when the can is upright, extend inwards either horizontally or obliquely in a uniform or alternating manner. The bead (3) can have an approximately semi-circular or triangular cross-section and preferably has an oblique lower part (3b) in order to completely empty the can. In one embodiment, a lid (7) engages in a positive fit with the bead (3) by an edge thickening (6).

Abstract: A can formed from an unfolded foldable cylinder having at least two folding edges. The folding edges are formed and arranged such that the foldable cylinder can be flattened for transport prior to the insertion of a closure member. The foldable cylinder is preferably unfolded and tightly sealed with at least one closure member at a first cylinder end region immediately before filling. By connecting the closure member to the foldable cylinder, the cylinder is given a desired shape or cross-section, at least in the region of the closure member. After the cylinder is filled, a further closure member is sealed to a second cylinder end region to seal the can and to impart the desired shape to the cylinder in the second end region, too.

Abstract: A can is closed with a membrane by heat-sealing, using a packaging apparatus with an inner, heat-sealing die and an outer sealing ring displaceably located around the heat-sealing die, wherein an outer surface of the heat-sealing die and an inner surface of the sealing ring are beveled slightly, preferably by approximately two degrees, in mating fashion.

Abstract: An inserted lid (1) for a box (2) is formed so that a contact region (5) can be pressed against the inside of the side wall of the box. In the non-inserted state, said side wall is slightly larger than the box opening (4). On insertion of the lid (1) into the box (2), the largest circumferential line of the contact region (5) must fit the inside of the side wall of the box as a result of an elastic deformation of the closure surface (3). To prevent the forces emanating on insertion from the side wall of the box from leading to irreversible deformations, the closure surface (3) has spring properties which are radial with respect to the contact region (5) and permit an elastic deformation of the contact region (5) in the radial direction. To ensure these spring properties, the closure surface (3) has a shape differing from a flat surface, in particular two concentric waves (7) formed constant distances away from the contact region (5) and/or a central vault (8).

Abstract: The can is closed on at least one end face with a membrane (2) of paper or plastic or metal foil in such a way that the outside of the foil edge region raised toward the can axis (3) is tightly connected to the essentially cylindrical inside can wall (1). An inverted lid (9) is mounted over the membrane (5), at the end face of the can. The membrane surface (5) comprises at least one contact region (7a, 7b) which projects toward the end face and, when the inverted lid (9) is mounted, can be placed at least partly on a support region (12a, 12b) of the inside of the lid surface (10). Consequently, the outward-directed forces acting on the closure membrane (5) are absorbed by the lid (9) and the danger of leaking membranes (5) is essentially eliminated. The cans according to the invention can be filled at high speed and with materials of high density, can be transported without precautions and can be exposed to large vacuums.

Abstract: In can production, a press apparatus is provided for tightly connecting a first contact surface of the can wall running around an axis to a second contact surface of a base, a lid or a closure membrane. If the press parts (16) are arranged essentially fixed in the axial direction or are held in a radial guide and can be moved radially by an actuating element (8) displaceable in the axial direction, the can need not also be moved during pressing. The contact regions of the can wall and of the separation element are guided in the region with the press surfaces. The end face of the can rests against a stop which is connected to the radial guide for the press parts and is immobile at least during the pressing process. Owing to the conical abutting region (18) between the actuating element (8) and the press parts (16), these can be pressed outward by means of an axial movement of the actuating element (8).

Abstract: The dispensing box comprises a cylinder (2, 11a) around a box axis (A), essentially comprising cardboard or paper, which is closed at the end by a closure element which is formed as a dispensing membrane (4a, 12) and essentially comprises cardboard or paper. Only a collar-like contact surface of the closure element is connected to a contact surface of the cylinder (2, 11a). The inside of the closure surface of the lid (3, 13) can be placed against the outer surface of the dispensing membrane (4a, 12). In a preferred embodiment, the lid (13) is connected to the dispensing box by means of a snap connection, rotatably about the box axis (A). For this purpose, a first projection (12b) overlapping the box cylinder (11a) on the outside is provided at the upper box edge and a second projection (13b) projecting inward is provided on the inside of the collar (13a) of the lid (13).

Abstract: Can-like containers are frequently closed or sealed with a diaphragm, the wall of which is provided with severance points, or the part of which that is U-shaped in cross section (3) covering the cut edge (15) of the can wall (17) is already located at least partially at a distance (a) from the nearly dish-shaped closure part (14). The diaphragm (14) according to the present invention has severance points that are formed by narrow ligaments (4) interrupted by cut-outs (5), said ligaments being arranged alternatingly along a circumferential line in the rim (2) of the diaphragm. A diaphragm for the closing of can-like containers is e.g. fabricated in that the foil is deep-drawn, and in the end phase of the closing movement cut-outs (5) are formed in its rim (2) by shearing edges (8 and 11). At least one shearing edge (8) is interrupted by notches (9), in the area of which ligaments (4) remain.
