Patent number: 10815025Abstract: A gable top carton and a carton blank for forming a gable top carton are provided having patterns of score lines positioned beneath a closure aperture that relieve stress during a folding operation to better allow the carton blank to be formed into a suitable gable top container. The score pattern is particularly useful for cartons where the closure assembly has a flange which may touch or overlap with one of the walls of the front face panel of the assembled carton and respective portion of the carton blank.Type: GrantFiled: February 17, 2017Date of Patent: October 27, 2020Assignee: EVERGREEN PACKAGING LLCInventors: Roderick W. Kalberer, Norsen Steen

Publication number: 20080105736Abstract: The present invention is for a divider for use with a food package, wherein the divider is manufactured from inexpensive coated paperboard and is of a simple one-piece construction. More particularly, a divider according to a preferred embodiment of the present invention is formed from a one-piece, foldable blank of paperboard material, which is folded in half and secured onto itself so as to form a two-ply, reasonably stiff construction. The divider is shaped and dimensioned to fit within a food container, which may preferably have a circular cylindrical shape, so as to bisect same and define two separate interior regions thereof. In addition, the divider includes a center portion wherein the paperboard material is not adhered onto itself, so as to allow the formation of a ring-shaped, cup-holding portion suitable for positioning and retaining a separate container within the package.Type: ApplicationFiled: November 5, 2007Publication date: May 8, 2008Inventor: Roderick W. Kalberer

Patent number: 6881180Abstract: A method and apparatus for forming a bottom closure of a container employing multiple assembly lines and including a universally foldable seal fin as a part of the bottom closure. A novel blank for the container is disclosed.Type: GrantFiled: May 23, 2003Date of Patent: April 19, 2005Assignee: International Paper CompanyInventors: Kimberly D. Ammons, Roderick W. Kalberer

Publication number: 20040104513Abstract: A coated paperboard blank is placed in the mold and formed into the desired shape of the container. Polymers injection-molded into specific areas about the carton blank to hold the blank together and prevent liquid leaks. Polymer is also injection-molded to form a handle providing easy carrying and pouring. A pouring opening can be injection-molded onto the container top. The bottom of the package has an injection-molded lip to receive a container bottom at a later time.Type: ApplicationFiled: November 26, 2003Publication date: June 3, 2004Inventors: Paul Allen Canino, Karl Whitney Davenport, Roderick W. Kalberer

Publication number: 20030132274Abstract: A container is formed by a single side wall wrapped around to complete an enclosed space. The package is produced with a barrier board including co-extruded polymers, mono-extruded polymers and/or films. The package may or may not have raw edge protection. The container uses a paperboard cup technology to create a bottom. The packages will be able to easily hold 64 and 96 fluid ounces and use a design very different from the conventional gable top container. The paper packages produced will cost less than plastic packages made with barrier materials.Type: ApplicationFiled: January 15, 2002Publication date: July 17, 2003Inventors: Roderick W. Kalberer, Paul A. Canino

Patent number: 5636771Abstract: A frangible pour spout construction is improved by the addition of reinforcing webs at the upper plug portion. These webs function to localize the upward pulling force to thereby concentrate the rupture force at the frangible connection between the upper plug and lower pour spout portions. This insures that the pulling force is concentrated so that the frangible connection will rupture prior to the entire fitment being pulled off of the container to which the fitment is secured. The upper plug, later to function as a cap or stopper for the lower spout portion, is provided with a pull ring. The entire construction is die molded, as for example of polyethylene, with the pull ring being molded substantially at 90.degree. from its flat or storage position. A pair of lugs carried by the upper plug holds the pull ring down in its storage position.Type: GrantFiled: June 6, 1995Date of Patent: June 10, 1997Assignee: International Paper CompanyInventors: Robert L. Gordon, Roderick W. Kalberer

Patent number: 5636785Abstract: A gable top type paperboard carton for juices and other pourable product which may attack the integrity of seals is formed with a pour spout fitment attached to one of the two sloping roof panels. The carton is formed so as to exhibit a rectangular cross section transverse to its longitudinal (vertical) axis, to thereby yield a gable top whose sloping roof panels extend upwardly from the narrower carton side walls. In use, the consumer grasps the two widest side walls of the carton by the thumb and one or more other fingers. This is in distinction to grasping the narrower carton sides, which would entail a wider finger grasp or span. The carton includes a V pocket forming panel in a first gusset, the V pocket receiving a V forming point or wedge on the second gusset. A similar V forming pocket and V point may be located on opposite bottom closure panels. Either V forming pocket may be of paperboard or of barrier film.Type: GrantFiled: April 24, 1996Date of Patent: June 10, 1997Assignee: International PaperInventors: Roderick W. Kalberer, Clarence R. Thompson, Patrick J. Smith

Patent number: 5244520Abstract: A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A first barrier layer lines the carton interior and and a second lines the carton exterior surface. A dispensing opening is formed, as by die cutting, in a panel of the carton. The two barrier layers span the dispensing opening, except for a concentric dispensing hole through them, with the two barrier layers sonically sealed together along an annular zone radially intermediate the dispensing opening and the dispensing hole. The pour spout carries a flange extending from the edge of the dispensing hole to a location radically beyond the dispensing opening, the flange sonically bonded to the outer barrier layer at three radially spaced, concentric zones. The spout screw cap is of a different polymer than the spout, to prevent bonding between the cap and spout.Type: GrantFiled: September 11, 1991Date of Patent: September 14, 1993Assignee: International Paper CompanyInventors: Robert L. Gordon, Roderick W. Kalberer
