The invention further relates to a packaging.
Abstract:
Method for arranging a foil in a tray, comprising: providing a tray (1) having a bottom, an upright wall, a tray opening and a circumferential outwardly extending flange composed out of at least two abutting portions; providing a foil (7) having at least dimensions corresponding with the outer dimensions of the flange; heating a central zone (15) of the foil; urging the heated central zone of the foil against the bottom, the upright wall and at least partially over the flange, wherein the edge of the heated central zone runs over the interfaces of abutting portions. Intermediate product with a foil lying loose over a flange of the tray. Device comprising a mould (5) for receiving a tray (1), means for arranging a foil (7) over the mould, heating means comprising a plate which is arranged over the mould for heating the foil and means for urging the foil in the mould.
Abstract:
Dispensing assembly for a carton having a liner. A pour spout or flap is mounted to a dispensing opening to pivot between an open and closed positions. The unfilled liner is bonded with a mandrel and clamp to the pour spout or flap in a way that when the spout or flap is initially opened, that portion of the liner bonded thereto separates from the rest of the liner, providing access to the contents thereof.
Abstract:
A packaging container which can be readily recycled after use and is high in thermal insulation. The food in the container can be heated by induction heating. The packaging container comprises a sleeve (12) folded inwardly at upper and lower ends thereof, a film (16) covering the sleeve (12), an inner container (11) molded in the sleeve (12), and a cover for closing the inner container (11) tightly. The film (16) and the inner container (11) are integrally fused to each other at the folded portions of the upper and lower ends of the sleeve (12). Since there is no need of providing a heat-activated adhesive and the like between the sleeve (12) and the inner container (11), and coating the inner surface of the sleeve (12) with a heat-activated adhesive and the like, the sleeve (12) is made easy to keep and handle.
Abstract:
A method for folding a liner for packaging and/or insertion into an overpack. The method may include providing a liner comprising a substantially tubular body portion and a closed top and bottom, and a fitment formed in or affixed to the top of the liner, forming a gusset in the bottom panel of the liner, forming a gusset in the body portion of the liner, and fan-folding the liner. In some embodiments, the top of the liner may be a substantially circular top panel and the bottom of the liner may be a substantially circular bottom panel, with the top panel being attached to one end of the tubular body portion and the bottom panel being attached to an opposite end of the tubular body portion. In other embodiments, the liner may be a flexible, blow molded liner, thereby having no weld seams.
Abstract:
The invention relates to an airtight, preferably oxygen-tight food packaging comprising a peripheral edge flange. The edge flange is lined with a plastic film, especially with a plastic composite film, which engages with the same inside. The inner space of the packaging is closed or sealed in an airtight, especially oxygen-tight manner over the edge flange by means of a covering film. In order to improve the producibility while ensuring a lasting air-tightness of the packaging, a shell part (40) is provided which at least partially forms the packaging base (41) and the side walls (43; 443). An uninterrupted collar which forms the edge flange (52) is placed on said shell part.

Abstract:
A method of assembling an intermediate bulk container from an outer envelope (76) comprising a prefabricated base from which extends a substantially tubular side wall structure of woven fabric and from a prefabricated, substantially tubular liner (70) of substantially impervious material. The material comprises fitting the liner over a former having support sections (37) that engage the liner along at least three circumferentially spaced axially extending regions of the interior thereof, reducing pressure in the space within the liner to cause parts of the liner each to take up an inwardly convex form between adjacent support sections, applying adhesive to at least part of the outer surface of at least one inwardly convex part of the liner, fitting the outer envelope over the liner with the inner surface of the side wall structure in contact with the outer surface of the liner in areas corresponding to the support sections and out of contact with the outer surface of the liner in those parts to which adhesive has been applied, expanding the liner outwardly into contact with the side wall structure and maintaining such contact until the adhesive maintains adhesion between the liner and the side wall structure. Apparatus for carrying out the method is also disclosed.
Abstract:
A method for manufacturing a sealable container including providing a container blank (126), wherein the container blank (126) is marked with indicia, shaping the container blank into a container structure (10), the container structure including an internal side and an external side, and laminating a film material (44) onto the internal side of the container structure, wherein the laminating step includes the step of drawing a vacuum through the container structure to urge the film material toward the container structure.
Abstract:
A container (10) comprises an outer shell (18) made from a paperboard or plastics material, the shell having a base (24), a side wall (26) and an opening (34); an inner lining (20) comprising a thin sheet (36) of plastics material, a first part of the lining being adhered to an internal surface (22) of the base and side wall of the shell by a suitable adhesive, and a second part of the lining conforming to a part of an external surface of the shell around the opening; and a handle assembly comprising an elongate handle (16) and an attachment plate (64) secured to each end of the handle, wherein at least a part of each attachment plate is secured to the second part of the lining on opposing sides of the opening and, in use, the lining and handle assembly are fully separable from the shell by peeling the lining away from the external and internal surfaces of the shell.
