A container erecting apparatus and methods are provided which advantageously increase the efficiency and production speed of erecting and sealing containers. The apparatus preferably includes a dispenser positioned to dispense one of a plurality of collapsed containers to be transported along a first predetermined path of travel and collapsed container erecting means positioned downstream from the dispenser for erecting the collapsed container. The apparatus also includes a first bottom panel folder and a container advancer positioned downstream from the container erecting means along the first predetermined path of travel. A second panel folder is positioned downstream and on a second predetermined path of travel which is transverse to the first predetermined path of travel. The apparatus also includes a container conveyor which is positioned along the second predetermined path of travel on which the apparatus has a third panel folder, an adhesive applicator for applying adhesive to selected portions of the folded panels, and a container compressor positioned downstream from the adhesive applicator along the second predetermined path of travel for compressing and sealing the bottom panels in a closed position.

[ That claimed is:] [1.]1. A container erecting and sealing apparatus for enhancing the production speed of container erecting and sealing, the apparatus comprising:collapsed container erecting means for erecting each of a plurality of collapsed containers during travel along a first predetermined path, the plurality of collapsed containers each having a plurality of non-folded bottom panels;first bottom panel folding means positioned in the first predetermined path of travel for folding a pair of the plurality of non-folded bottom panels, said bottom panel folding means including bottom panel positioning and container advancing means positioned to move the pair of the plurality of non-folded bottom panels of each erected container inwardly toward each other and advance the erected container downstream along the first predetermined path of travel;second bottom panel folding means positioned to overlie at least one of the non-folded bottom panels of an erected container and downstream from the first bottom panel folding means along the first predetermined path of travel for inwardly folding the at least one of the non-folded bottom panels downwardly to thereby contact the folded bottom panels;conveying means positioned along a second predetermined path of travel transverse to the first predetermined path of travel for receiving and conveying the plurality of erected containers along the second predetermined path of travel;third bottom panel folding means positioned adjacent said conveying means along the second predetermined path of travel for folding a remaining non-folded bottom panel inwardly to a position closely adjacent the previously folded bottom panels;adhesive applying means positioned downstream from the third bottom panel folding means along the second predetermined path of travel for applying adhesive only to selected portions of the bottom panels; andcompressing means positioned downstream from adhesive applying means along the second predetermined path of travel for compressing the outer surfaces of the bottom panels to thereby seal the bottom panels in a closed position, the compressing means having portions thereof extending into the erected containers to abuttingly contact portions of the bottom panels and retracting out of the erected containers after compressing the outer surfaces of the bottom panels so as to allow another erected container to receive portions of the compressing means.
