A composite container is provided for holding one or more products (e.g., snack foods, toys, etc.) in separate compartments within the same container. The container includes a tubular body defining a first end and a second end, and the tubular body extends radially inward at a predefined location between the first and second ends to form a ledge. A separator, such as a paperboard or plastic disk, can be placed on the ledge, such that the separator defines a first compartment on one side of the separator and a second compartment on the other side of the separator. In this way, a product can be stored in the first compartment, and a product can be stored in the second compartment, and the user can have access to both in the same container. Associated methods of manufacturing a composite container with multiple compartments are also provided.

An apparatus for coiling a paper strip is disclosed. The apparatus includes a housing, a pin and a plunger. The pin having an end positioned external to the housing and an axis of rotation, the end having a slot elongated along the axis of rotation, the slot being sized to receive the paper strip. Further, the plunger is disposed on the housing and configured to translate away from the pin, the plunger having a plunger head positioned proximate to the slot of the pin, the plunger head having a surface aligned to press the paper strip against the pin.

A can to contain a liquid and/or a gas is closed with a bottom element and a cover element. The innermost layer is a straight-wound barrier layer having a folded seam extending in a longitudinal direction. The barrier layer includes an inner diffusion-tight layer and an outer kraft paper layer. At least two further straight-wound layers made of paper or cardboard are around the barrier layer of the can shell. Adjoining cardboard or paper surfaces of the barrier layer and a next wound layer are adhered directly to each other. Each of the two further wound layers is longitudinally wound and include in the longitudinal direction an overlapping region with itself. The overlapping region of the next wound layer adjoining the barrier layer is offset relative to the folded seam of the barrier layer and the overlapping regions of the two further wound layers are located at different peripheral regions.

A manufacturing machine and a manufacturing method for the production of a filter for a tubular element. There are provided: a folding conveyor, which moves at least one first pocket along a folding path, said first pocket being designed to house a sheet made of card stock and having an inner portion and an outer portion; a feeding station, where the first pocket receives the card stock sheet and engages the sole outer portion of the card stock sheet, leaving the inner portion of the card stock sheet free; a first folding station, where the inner portion of the card stock sheet left free by the first pocket is folded like the bellows of an accordion; and an insertion station, where the first pocket releases the card stock sheet having the inner portion folded like the bellows of an accordion.
