Abstract: A method for forming a container having container side walls and a lid. The container side walls have end edges. The lid has a central panel, side panels attached to the central panel by score lines, and an annular crushed area conterminous with the score lines in the central panel. The liners and the corrugated material are crushed together in the crushed area. In the method the container walls are opened, the lid blank and the container walls are moved relative to each other until the end edges of the container side walls are aligned with the crushed area, the container side walls and the lid are moved relatively toward each other until the container side walls are seated in the crushed area, the lid side panels are folded onto the container side walls and fastened to the container side walls. In one embodiment the lid is of fiberboard material and the side walls of the container are aligned with the score lines of the lid.

An unfolding preventing guide member 73 is disposed in the rail clearance C so as to come into contact with a required part of the bottom forming portion 14 during movement through the clearance.

Abstract: A apparatus for manufacturing an object of a folded sheet material has improved slitting, scoring/crushing, gathering, and folding sections or devices. Qualifying means, slitting means, and scoring/crushing means are adjustable with respect to a flat, planer, path of movement so that sheet material moves through the machine without causing the paper to assume an "S" shape, or otherwise suffer loss of paper control. Qualifying means bring within tolerance, sheet which is over thickness. Identifying rollers identify and slightly pre-fold a blank before it enters a gathering and pre-folding section. Novel slitting and scoring heads are easily changed in number or configuration, and have easily replaceable split blades.

Abstract: A method of forming a paper container uses a three ply corrugated material having at least one inner or outer sheet of paper that may be stretched or compressed circumferentially to permit subsequent rolling of the corrugated material about a mandrel. A flattening of the upper and lower edges of the corrugated material permit rolling and seaming operations to be used to assemble the bottom to the cup and to form a lip in the upper edge.

Abstract: A modular cushioning conversion machine for converting a sheet-like stock material into a cushioning dunnage product characterized by first and second modular units. The first unit includes a housing and a forming assembly within the housing which forms the sheet-like stock material into a three-dimensional strip. The second unit includes a housing and a feed mechanism within the housing which feeds the sheet-like stock material through the forming assembly. The housings of the first and second units respectively have an outlet opening and an inlet opening positionable with respect to one another to provide a pathway for the transfer of the strip from the first unit to the second unit.

Abstract: A container having a number of walls of cardboard, fiberboard, plastic or other relatively stiff sheet material, joined along corner edges is made collapsible by providing one or more accordion folds transverse to the corner edges. Each accordion fold includes parallel crease lines on a common side of the walls, an intermediate crease line on an opposite side of the walls, and diagonally opposed areas of locally weakened stiffness in the wall material adjacent each intersection of the intermediate crease with the corner edges, such that portions of each accordion fold tend to overlap at the corner edges to facilitate bellowing action of the accordion fold.

Abstract: A device for bending down and sealing triangular lugs that are formed on the top of a cardboard carton includes a conveyor for moving cartons in a running direction with the cartons having outstretched lugs. A plurality of clamp sets are connected to the conveyor which each include a base plate to which is connected a vertically downwardly extending pushing plate that pushes the cartons. Two or more spaced apart clamp members are movable on the base plate for movement toward each other and away from each other. A driver on the base plate has a cam follower and cooperates with a clamping cam to move the clamp members together and apart. A hot air blower is provided for blowing hot air against the undersurfaces of the lugs and side surfaces of the carton which are partially fused. A push up bed is used to push a carton up between the clamp members to bend the lugs down to sides of the carton.

Abstract: An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material. The carton preferably includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carton may be consumed by a user. The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carton blank upon a rotating heat sealing and alignment drum.

Abstract: An improved multi-station machine is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs. The machine employs a rotatable dial plate, carrying eight mandrels and an improved ring clamping system, which dial plate is incrementally rotated by an automatic indexer assembly relative to the various operating stations which consist of a ring feed station, a disc feed station, an adhesive dispensing station, a curling station, a grooving station and a closure ejecting station. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate. The improved disc feed station automatically feeds the lowermost disc from a stack of discs to a position over a ring on the dial plate and simultaneously forms a peripheral skirt on the disc and positions it in an open end of the ring.
