A method of sealing a peelable lid to a circumferential and inwardly projecting flange formed in a tubular metal can body, where the flange has a sealing surface having a substantially V-shaped profile. The method comprises pressing the peelable lid against the sealing surface of the flange using a punch, an engagement surface of the punch having a generally V-shaped profile such that the apex of the punch presses the peelable lid into the valley of the engagement surface of the flange.

A method of producing and filling a paperboard packaging container with pulverulent bulk solids includes forming a tubular container body from a paperboard sheet, the body having upper and lower body openings and a container wall extending between the upper and lower body openings and having inner and outer surfaces; closing the upper body opening with a sealing membrane attached to the inner surface; providing an upper reinforcing rim; inserting at least a lower part of the upper reinforcing rim into the tubular container body at the upper body opening; forming a weld seal between the inner surface and the inserted part of the upper reinforcing rim; presenting the body to a filling station with the bottom body opening of the container body directed upward in a vertical direction; filling pulverulent material into the body through the upwardly directed bottom body opening; and closing the bottom body opening.

A metal container body 1 comprises a base and a generally cylindrical side wall 3. The top edge of the cylindrical side wall is rolled over to form a hollow annular bead 5 surrounding the upper open end of the container body and a notch 6 is formed at a circumferential point in the annular bead. The container body is for use with a releasable closure 2 formed with an end wall 7 and a depending skirt 8 and having an annular layer of sealing material 9 provided on the inside of the end wall adjacent the skirt. When the closure is pressed onto the container body, the annular bead engages the annular layer of sealing material and some of that material extends into the notch 6. The closure is held on the container only by the partial vacuum formed therein during processing of a food product in the container. After processing, the user opens the container by rotating the closure. Sealing material in the notch forces the closure to lift off from the container to break the seal and release the closure.

A method of collapsing a collapsible box includes providing the collapsible box, the collapsible box comprising: a plurality of side panels including a first side panel and a second side panel, each of the plurality of side panels defining a side panel top edge; a box bottom; and a box top comprising a plurality of top panels including a first top panel extending from the side panel top edge of the first side panel and a second top panel extending from the side panel top edge of the second side panel, the second top panel comprising an overlapping portion; folding the first side panel towards the second side panel to confront the first side panel with the second side panel; and folding the overlapping portion of the second top panel over a top panel top edge of the first top panel.

A sheet metal lid has a rim portion with a resilient sealant for releasably coupling and sealing the lid to a glass or other container enclosing a vacuum food product. The lid is successively pressed with progressive dies to form an upwardly projecting and thinner dome-shape portion which is progressively formed into annular cavity surrounding a vacuum release vent button. The button has a sloping top wall with an upper edge portion connected to a substantially vertical arcuate wall portion adjacent an arcuate score line located in opposing relation to an arcuate reinforcing bead within the cavity. A sealant material is bonded to the inner surface of the button and overlies the score line. The vent button is preferably located below the rim both before and after the vacuum is released, and the sealant material reseats to cover the score line and protect the food product.

A package includes a container and a lid adapted to mate with a brim of the container. The lid closes a top opening in the container when mounted on the container. In a lid-coupling process, a product is discharged from an interior product-storage region formed in the container. The elastic top wall of the lid is moved along the container brim to establish a radially outwardly moving brim-wiping motion to cause substantially all of any spilled product located on the annular brim to be displaced and wiped off the container brim so that little, if any, spilled product remains on the container brim.

A food container has a temporary rim formed in one-piece structure on the edge thereof. It has as first sealing rim and a second sealing rim as the surface for a sealing film to be heat-sealed thereon. When the outer rim is torn off, an irreversible tear-off structure on the sealed cover would leave the trace, allowing the consumers and the sellers to decide whether to purchase or dispose of the goods simply by visual judgments; in other words, it has a tamper-proof function. In addition, when the outer rim is removed from the container, the sealing film would detach from the first sealing rim but still stick on the second sealing rim, providing a reusable sealed cover for the container that ensures more safety of food hygiene.

Among other things, a container has a chamber and an open end of the chamber. The container is configured at the open end to be surrounded by lips of a user to permit the user to apply suction to the chamber through the open end. A gelled dose of a therapeutic agent in the chamber is in contact with a wall of the chamber and is between the wall of the chamber and the open end. There is at least one hole in the wall for air to reach the gelled dose when the user is applying the suction to the chamber to release the gelled dose into the user's mouth. A mechanism prevents contamination of the gelled dose through the hole in the wall until the user is ready to consume the gelled dose and permits air to reach the gelled dose through the holes when the user is ready to consume the gelled dose.

A tab-less metal can end for seaming onto a metal can body. The can end comprises a substantially circular and planar panel, a chuck wall extending around the periphery of the panel and defining a curl, and a discontinuous score formed in said panel and following a circular path substantially concentric with said chuck wall, the score defining a hinge between first and second ends of the score.

A package made of sheet material with a tear-off foil cover includes a seamless frame (1) produced by deep drawing, which forms a package wall (6) enclosing the interior space of the package. At a first end (T), the frame (1) forms an extraction opening surrounded by a sealing flange (2), which is closed by a tear-off foil cover (3) sealed onto the sealing flange (2). At its other, second end (B), the frame (1) is connected by flanging to a sheet metal cover (4) which forms the package bottom (7). The package can be produced inexpensively with low energy and material consumption from both steel sheet material and aluminum sheet material, has no weld seams, can be tested for leaks before filling, and enables high filling speeds.
