Abstract
A cardboard carton is constructed that is particularly useful for holding a stack of paper so that individual cut sheets from the stack may be readily removed. The carton bottom has an open top and substantially open ends and closed sides, while the carton top has a Z-fold top panel, and one or more tear strips between adhesive connecting the carton top to the carton bottom and the main part of the carton top. The carton bottom, with its open top facing downwardly, is either moved over a stack of paper, or formed over the stack of paper. Then it is rotated 180.degree. about a horizontal axis (as by pivoting a U-shaped continuous conveyor about a horizontal axis), and conveyed to a station where it is moved with respect to a carton top so that the open bottom of the carton top goes over the carton bottom, and then is glued in place. Two opposite flaps on the carton lid may be glued to the bottom surface of the carton bottom panel to provide a lifting space beneath the carton. The side and end flaps of the carton bottom may be connected to the bottom panel by perforations to allow ready detachment.

6094890 - Thermoforming, filling, and capping receptacles - Owned by Erca S.A. (Les Ulis Cedex,FR)

An apparatus and method for making a receptacle from a generally flat thermoplastic blank has an upstream conveyor extending along a path in a transport direction through a loading station, a heating station downstream of the loading station, and a forming station downstream from the heating station. The conveyor has a plurality of supports forming a plurality of respective throughgoing apertures spaced apart in the direction. A supply at the loading station positions a respective blank atop each of the apertures of the conveyor with a central region of each blank exposed through the respective aperture and a periphery of each blank engaging and supported by the respective support A drive connected to the conveyor advances it and the blanks carried on it step-wise through the heating and forming stations. At the heating station at least the central region of each blank is heated to a softening point. A die forming a cavity open transversely toward the path at the heating station coacts with a piston at the heating station displaceable transversely across the path into and out of the die. Displacement of the piston into the die at the forming station presses the heated central region of the blank therein into the die cavity and thereby forms the blank at the forming station into a receptacle.
