Provided Is a technology whereby defects can be suppressed when blanks are rolled and end sections bonded, during molding of paper containers including paper cups and paper sleeves. The blank is embossed, one end of the blank is folded in towards the center of the container, a fold line L is formed, the blank is curled around to make a curved surface, one end 2 of the blank is arranged on the lower side and the other end 1 of the blank on the upper side, the one end 2 and the other end 1 of the blank are bonded, and an inverted cone or cylindrical shape is formed.

A container forming apparatus for forming a container from a blank includes a blank transfer station including an adhesive assembly having a plurality of adhesive applicators, and a compression station downstream of the blank transfer station, the compression station including a vertically movable mandrel and a forming tool below the mandrel. The forming tool defines a cavity therein and has an inner profile complementary in shape to an outer profile of the mandrel. Hot-melt adhesive is applied to a surface of the blank as the blank is transferred through the adhesive assembly. The blank is positioned beneath the mandrel, and the mandrel drives the blank downward into the cavity of forming tool. Compression plates fold panels of the blank, and the formed container includes a fully formed top flange.

A method for forming an overwrap container includes the steps of a) providing a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom secured to the side wall; b) providing the side wall of the base container with connecting elements on an outer periphery of the side wall; c) providing an overwrap having a second side seam over the side wall of the base container such that the overwrap is joined in spaced apart relationship by the connecting elements to the side wall of the base container; d) clamping the overwrap to the base container along the second side seam to form a first compressed area; e) clamping the overwrap to the base container in an area 180° removed from the second side seam to form a second compressed area: and f) reforming the second compressed area to define an overwrap container having a substantially uniform spacing and air gap between the base container and the overwrap except in the first compressed area.

A method of forming a tray includes obtaining a blank, positioning the blank in a blank feeder assembly of a system for forming a tray, moving the blank from the blank feeder assembly to a nipping assembly, and moving the blank to a tray forming assembly, the tray forming assembly including a tray forming apparatus. The method further includes positioning the blank between a first tray forming portion of the tray forming apparatus and a second tray forming portion of the tray forming apparatus, the first tray forming portion includes a forming block that defines an interior, and the second tray forming portion includes a tray forming member, and driving the forming block into engagement with the blank and the tray forming member such that the blank and the tray forming member are at least partially received in the interior of the forming block to form a tray.

The technology described herein generally relates to particular form of folded package. The package packages loose particles into a conical container and secures the filling with a folded distal end. More specifically, loose plant matter, such as crumbled dried leaves, are supplied as filling and the package may further be provided with a fluid core.

A method for manufacturing an object, such as a tray includes providing an unfolded sheet; providing a straight score line in the unfolded sheet for providing a division between a wall part and a flange part; folding the flange part of the sheet relative to the wall part along the score line to provide an angle larger than 45° between the flange part and the wall part; providing a plastic foil; heating the plastic foil; pressing the heated foil on the sheet at the side provided with the score line and covering at least part of the wall part and the flange part; the sheet having at least one U-shaped cut interrupting the score line. The free ends of the U-shaped cut are positioned on the score line. The bridging part of the U-shaped cut is positioned in the flange part.

A horizontal high-speed paper cup/paper bowl forming machine is provided. Specifically, the seven-station main rotation tower forming mechanism has a stamping die station, a paper feeding connection station, a first cup bottom preheating station, a second cup bottom preheating station, a bottom crimping station, a rolling station, and a main and auxiliary tower connection station. The seven-station auxiliary rotation tower forming mechanism has the main and auxiliary tower connection station, a cup rim lubrication station, a pre-crimping station, a first final crimping station, a second final crimping station, a cup outlet station, and a reserved vacant station. The stations arranged in sequence along the circumferential direction of the seven-station main rotation tower forming mechanism is in an opposite order to the stations arranged in sequence along the circumferential direction of the seven-station auxiliary rotation tower forming mechanism.

Methods for securing a shrinkable film to a paperboard substrate and methods for making paperboard containers therefrom. In one or more embodiments, a band of adhesive may be applied about a perimeter of a paperboard substrate having a first edge and a second edge opposed to one another and a third edge and a fourth edge opposed to one another. The band of adhesive may surround a first area that is substantially free from the adhesive. A second area that may be substantially free from the adhesive may be located along a portion of the third edge, between the first and second edges. The first area and the second area may be separated by the band of adhesive. A shrinkable film may be secured to the paperboard substrate with the adhesive to produce a paperboard blank. The third edge and the fourth edge may be overlapped to form a sidewall. A bottom panel may be secured to the sidewall at or adjacent the second edge. The first edge may be curled to form a brim.

A double-walled cup and a process for production of the cup are described. The cup includes an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by joining the ends of the blank before being slid on, whereby the ends of the blank are joined by an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.
