Patent number: 10029811Abstract: The present invention concerns a method of splicing two sealing strips and a sealing strip formed by the method. The sealing strip is placed at longitudinal edges of a packaging material web, used for packaging containers for liquid foods. The sealing strips to be spliced are cut each forming an oblique edge of about 45°, as seen in plan view. The oblique edges are then placed one on top of the other forming an overlapping area. The overlapping area is in the form of an oblique band having a length of about 3 mm. The ends of the sealing strips are then fused together by heating both from one side at the overlapping area.Type: GrantFiled: May 25, 2010Date of Patent: July 24, 2018Assignee: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventor: Ingemar Larsson

Patent number: 8382648Abstract: A method for manufacturing boxes made of paper or cardboard, whereby the boxes have a base or a lid with a glued-on sidewall and the sidewalls are formed from a strip with a beginning, an end, and connecting tabs on a long side. First, the connecting tabs are bent by about 90°. Next, the strip beginning is placed against the lateral surface of a cylindrical matrix, whose cross section corresponds to the cross section of the box, with the aid of a patrix and attached by vacuum. Next, the matrix is rotated. In so doing, the strip is suctioned by vacuum onto the lateral surface and held in place. After application of an adhesive at the beginning or end of the strip, the beginning and end of the strip are glued together. A base along whose periphery an adhesive bead is applied is then pressed onto the connecting tabs. After the adhesive has hardened, the finished box can be removed from the matrix.Type: GrantFiled: February 22, 2010Date of Patent: February 26, 2013Assignee: Mohrbach Verpackungsmachinen GmbHInventor: Lutz Demuss

Patent number: 5599267Abstract: The present invention relates to a method and apparatus for making display boxes having windows made of substantially rigid plastic material. The boxes comprise substantially rigid opaque material, such as paperboard, in combination with substantially rigid plastic material. The substantially rigid plastic material includes at least one fold line or groove which cooperates with a fold line in the opaque material when the box is set up. The present invention provides a method and apparatus for making such boxes from a supply of sheets of the opaque material and a supply of sheets of the plastic material. The method comprises the steps of supplying a sheet of opaque material with an opening, positioning a supplied sheet of plastic material into juxtaposition with the sheet of opaque material to cover the opening, adhering the plastic material to the opaque material, and forming groove lines in the plastic and opaque sheets to permit folding of the sheets along aligned groove lines.Type: GrantFiled: June 7, 1995Date of Patent: February 4, 1997Assignee: Klearfold, Inc.Inventor: Francois Dupuy

Patent number: 5540645Abstract: The present invention relates to a method and apparatus for making display boxes having windows made of substantially rigid plastic material. The boxes comprise substantially rigid opaque material, such as paperboard, in combination with substantially rigid plastic material. The substantially rigid plastic material includes at least one fold line or groove which cooperates with a fold line in the opaque material when the box is set up. The present invention provides a method and means for making such boxes in a single machine from a supply of blanks of the opaque material and a roll of ungrooved plastic material. The machine comprises means for feeding of the opaque blanks, feeding of a length of the plastic material, means for forming at least one groove in the length of plastic material, means for cutting the grooved plastic material into sheets, and means for juxtaposing and joining the blanks of opaque material and the cut plastic sheets of material.Type: GrantFiled: September 13, 1994Date of Patent: July 30, 1996Inventor: Francois Dupuy

Patent number: 4871345Abstract: A shipping carton or container that can be readily opened and converted into a display tray without having to use a knife or other sharp instrument. The carton is formed from a blank having four sidewalls and hingedly connected top and bottom end panels. The sidewalls have a line of severance running circumferentially around the carton that defines a continuous butt joint separating the carton into a top cover section and a bottom tray section. A wide tape having a narrow tear filament or strip attached to its inner surface is adhesively attached to the sidewalls' outer surface such that it bridges the butt joint and holds the carton's top and bottom sections together, the tear strip being substantially superimposed over the butt joint. Pulling the tear filament neatly splits the wide tape and separates the carton's top and bottom sections.Type: GrantFiled: August 1, 1988Date of Patent: October 3, 1989Assignee: The Procter & Gamble CompanyInventors: Charles L. Wosaba, II, Peter W. Hamilton, Robert J. Kissner

Patent number: 4331434Abstract: 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.Type: GrantFiled: July 27, 1979Date of Patent: May 25, 1982Assignee: Pneumatic Scale CorporationInventor: Josef Buschor

Patent number: 4306849Abstract: The present invention is directed to an apparatus and method wherein bottom blanks for containers are severed from a web feed roll and subsequently transferred at a compatible speed and spacing to final forming mandrels on which finished containers are to be formed. The bottom blanks are tangentially transferred from a first transfer turret at a final velocity and spacing most desirable for cutting and minimizing scrap to a second transfer turret at a second velocity and spacing and thereafter tangentially transferred to the final forming mandrels. Subsequently, preprinted rectangular blanks of longitudinally stretch-oriented foam sheet material formed into cylinders are transferred onto the final forming mandrels. Thereafter, the bottom blanks the cylindrical blanks and the final forming mandrels are heated to shrink the cylindrical blanks so that they assume the shape of the final forming mandrels. The top curl on containers such as drinking cups and food tubs is formed after shrink forming.Type: GrantFiled: October 23, 1978Date of Patent: December 22, 1981Assignee: Maryland Cup CorporationInventors: Allan K.
