A bottom heater for use in assembling a container bottom and a sleeve includes a body having a peripheral wall and a heated air passage terminating in an outlet in the peripheral wall. A shape of at least a portion of the peripheral wall defining the outlet is such that heated air exiting the outlet is fluidly attached to an adjacent portion of the peripheral wall after exit because of the Coanda effect.

A method for embossing a barrier paper, wherein the barrier paper comprises paper and a protective layer on at least one of its sides. The method comprises providing a first embossing system with a first embossing tool and a second embossing tool cooperating with the first embossing tool to emboss the barrier paper: providing a patrix structure on the first embossing tool: providing a matrix structure on the second embossing tool: whereby the matrix structure corresponds to the patrix structure in such a manner that when embossing the barrier paper, a functionality of the protective layer is preserved. The method further comprises embossing the barrier paper by inserting the barrier paper between the first and the second embossing tools, applying pressure between the patrix and the matrix structures to press the patrix structure on a paper side which is a side of the barrier paper opposite to the side with the protective layer of the barrier paper, and push the barrier paper in the matrix structure, whereby the protective layer faces the matrix structure, thereby modifying a fiber structure of the paper in the barrier paper by at least one of the following effects: breaking of paper fibers, compressing of the paper fibers, densifying of the paper fibers; resulting in a modified folding behavior of the barrier paper and in maintaining a substantially unchanged shape of the barrier paper over its lifetime.

A collapsible bulk material container apparatus, kit and method of assembly employ a forming member having a plurality of interconnected sidewalls, a locking mechanism that fixedly orients the sidewalls continuously about an internal bulk material receiving cavity, and a tubular open-ended woven fabric sleeve that supportively overlies the sidewalls. A connector system rapidly engageable during container assembly, fixedly secures the support sleeve of an unloaded container against subsequent upward movement along the sidewalls. Strategically located friction reducing surfaces of the forming member facilitates sliding assembly of the sleeve over the forming member sidewalls.

A method of making a container having a separable inner lining and outer shell comprises the steps of: forming an outer shell having a base, a sidewall and a rim surrounding an opening of the shell; preforming a flexible lining, at least a part of the lining conforming to a complete internal shape of the shell; inserting the pre-formed lining into the shell so that a first part of the lining is within the shell and a second part of the lining protrudes from the opening of the shell; adhering the first part to an internal surface of the shell; conforming the second part to an external surface of the shell; and attaching to the lining around said rim a sealing layer covering the opening, the sealing layer being peelable from the lining such that the lining remains intact, and the adhesion between the lining and the internal surface of the shell being such that the lining is peelable from the shell while remaining intact.

A blank of sheet material for forming a container is provided. The blank of sheet material includes at least one major bottom panel, two opposing side panels, and two opposing end panels. Each end panel includes a plurality of fold lines that define two opposing side edges, a first minor end panel, a second minor end panel, and at least two reinforcement panels positioned between the two side edges. The at least two reinforcement panels are configured to move inwardly towards an interior cavity of the container forming a reinforcement structure when the container is formed.

A method of making a container (2, 30) having a separable inner lining (6) and outer shell (4) comprises the steps of: forming an outer shell; pre-forming a flexible lining, at least a part of the lining conforming to a complete internal shape of the shell; inserting the preformed lining into the shell so that a first part of the lining is within the shell and a second part of the lining protrudes from the opening of the shell; adhering the first part to an internal surface (8) of the shell; conforming the second part to an external surface of the shell; and attaching to the lining around said rim a sealing layer covering the opening, and the adhesion between the lining and the internal surface of the shell being such that the lining is peelable from the shell while remaining intact.

A new package or box type having an internal core or frame structure comprising of plastic or other polymer material sandwiched between two cardboard sheets an all sides of the box forming the outer walls of the box. The walls of the box containing the frame structure are more resistant to bursting or crushing than conventional corrugated cardboard used in the industry for transporting goods. Use of plastic or polymers applied to the core frame results in less material consumption than conventional corrugated cardboard. This invention yields higher package strength throughout the package structure and not just the edge of the package in order to negate the use of the double corrugated walls design as widely used in corrugated card board to achieve similar package strength quality while minimizing package weight and preserving exterior package composition of cardboard for handling purposes.

An apparatus to create corrugated cardboard on the site of a system for automatically forming packaging boxes for packaging an arrangement of one or more item(s) to be shipped, said corrugated cardboard having at least one corrugated layer between two flat layers, comprising at least two supply stations for supplying two different single-faced corrugated cardboards, each single-faced corrugated cardboard comprising a corrugated layer (having a closed side with an attached flat layer and an open side opposite to said closed side, a supply station for supplying a closing layer, a microprocessor communicatively coupled to obtain information on the arrangement to be shipped, the information relating to at least one of overall dimensions, weight, shape, shipping conditions, fragility, sensitivity to moisture, value, shipping destination, and the obtained information allowing selection, based on the obtained information, of at least one of said at least two different single-faced corrugated cardboards, and an attaching station that attaches the closing layer to the selected first single-faced cardboard to sandwich the corrugated layer between the flat layer and the closing layer.

A reinforced package comprising a carton comprising a plurality of panels that can comprise a first side panel connected to a front panel along a first fold line, a back panel connected to the first side panel along a second fold line, and a second side panel connected to the front and/or back panels. The reinforced package further can comprise a bag that can have an at least partially open end, an at least partially closed end, and an interior space. The carton can be positionable in non-erect and erect positions, and the carton can be configured to support the bag in the erect position. The first and second side panels can comprise retention features for at least partially retaining the carton in the erect position, and the retention features can comprise at least a V-shaped fold line extending in the first side panel from the first fold line.

A container for holding at least one article includes a body extending at least partially around an interior of the container, a closed top engaged with the body, a closed bottom engaged with the body, and a barrier member positioned in the interior of the container, the barrier member comprising a laminate structure that includes at least one polymeric layer with an uninterrupted lower portion.
