Abstract:
A container can comprise a sidewall extending at least partially around an interior of the container, and the sidewall can have at least a first end margin and a second end margin. The sidewall can comprise at least a sidewall substrate layer, a sidewall base coat extending along the interior of the container, and a secondary layer extending in register along at least the first end margin of the sidewall. The container further can comprise a sidewall seam comprising the first end margin and the second end margin in an at least partially overlapping relationship. The secondary layer and the sidewall base coat extending along the first end margin can cooperate to form a heat seal along the sidewall seam.
Abstract:
A package (1) for a powdered nutritional product. The package (1) includes a sidewall (36) of tubular shape having an upper end (31) and a lower end (30), made from a sheet of paperboard laminate. The laminate sheet has opposed edges (39A, 39B) brought together and butt-jointed at a vertical seam (40) and comprises at least innermost layer of heat-sealable polymer, an oxygen barrier layer(46) and a core layer (44) of paperboard, the sidewall (36) further comprising an outermost detection layer (50). A base (38) is joined to and closes the lower end (30) of the sidewall (36) to form a container (3) defining a product containing space in which a quantity of the powdered nutritional product is located. The product containing space is hermetically closed prior to use by a membrane seal (4) which is at least partially removable to gain access to the product. The package (1) also includes a closure (2). The closure (2) has a circumferential rim (20) connected to the upper end (31) of the sidewall (36) defining an access opening (27) and a lid (21), pivotably attached to the rim (20), for selectively closing the access opening (27).

Abstract:
A multi-layer sheet for forming an expanded foam container, the multi-layer sheet comprising a first layer of an expanded foam material comprising a first polyolefin-based material comprising at least one polypropylene-based polymer and a second layer of an unexpanded material comprising a second polyolefin-based material comprising at least one polypropylene-based polymer that is co-extruded, extrusion coated, or laminated on a first side of the first layer, wherein an exterior surface of the second layer has a low gloss level.
Abstract:
A double wall paperboard container (100) is disclosed that includes: a container body (102) with a first sealing structure (160) on an upper end portion (110) and a second sealing structure (162) on a lower end portion (112); a lid (104) sealingly connected to the first sealing structure; and a bottom (106) sealingly connected to the second sealing structure. The container body includes: an inner wall (116) having a first edge and a second edge and an outer wall (118) having a first edge and a second edge, wherein the first edge of the inner wall is connected to the first edge of the outer wall along a longitudinal fold (146). The inner and outer walls extend about a longitudinal axis such that the second edges of the inner and outer walls overlap the longitudinal fold to form a longitudinal seam (152). The double wall structure may provide enhanced strength and gas barrier performance to the paperboard container.
Abstract:
The method for forming a container that comprises the following stages: the forming of the sidewall blank (O) from a blank by wrapping it into a form that is closed in its horizontal section and by seaming its opposite edges together; the sealing of the sidewall blank at one end with a lid member (P), which is equipped with a discharge hole (P1); the sealing of the sidewall blank at the other end with a bottom member (R); and the filling of the container. At first the lid member (P), the discharge hole (P1) of which is completely sealed with an openable closing member (P2), is inserted into the end of the sidewall blank (O). Thereafter the container is filled through the end of the sidewall blank (O) that was left open, and the container is sealed to form a tight container by sealing the end that was left open with the bottom member (R).

Abstract:
Fluidbehälter bestehend aus mindestens zwei Lagen von zu einem Hohlzylinder gewickeltem Kartonverbund-Material aus Kraftpapier, dessen Ränder sich in Wickelrichtung überlappen. Die Überlappungsbereiche der mindestens zwei Lagen liegen Bezug auf den Umfang der Wicklung an versetzten Stellen. Eine Seite des so gebildeten offenen Hohlzylinders ist mit einem Bodenelement (4) verschlossen. Die andere, noch offene Seite des Hohlzylinders wird nach Befüllung mit einem Deckelelement (5) mit Verschluss in gleicher Weise verschlossen ist. Für die bedarfsweise, zeitgerechte Herstellung eines solchen Fluidbehälters wird der Dosenkörper (2) durch mindestens zwei Lagen von Umwicklungen aus Kartonverbund-Material bzw. Kraftpapier erzeugt. Die Überlappungen der Umwicklungen werden an unterschiedlichen Stellen des Dosenumfanges angeordnet und die überlappenden Randbereiche der Umwicklungen des Kartonverbund-Materials werden in eine Stufe geschnitten, sodass sich diese Randbereiche formschlüssig überlappen und ihre Dicke der Dicke des Kartonverbund-Materials entspricht. Die mehrlagigen verleimten Umwicklungen werden hernach rechtwinklig zur Achse der Umwicklungen in gewünschte Rohrabschnitte geschnitten. Eine Seite der Rohrabschnitte wird mit einem einsetzbaren Bodenelement (4) ausgerüstet, dessen axial auslaufender Rand dichtend um den Rand des Rohrabschnittes gekrempelt wird. Danach wird die Dose befüllt und hernach wird ein Deckelelement (5) in gleicher Weise wie das Bodenelement eingekrempelt.
