Patent number: 6328204Abstract: An over-folded, sealed bottom carton defining an interior storage region includes a plurality of side panels defining upstanding walls. The panels include first, second, third and fourth panels that are separated from adjacent side panels by longitudinal crease lines. A plurality of top panels define a sealed top. A plurality of bottom panels define a sealed bottom. The bottom panels extend from respective, adjacent side panels and separated from their respective side panels by a transverse crease line. Each bottom panel has a length relative to the transverse crease line. The bottom panels are contiguous with adjacent bottom panels and are separated from adjacent panels by the longitudinal crease lines. The bottom panels include rectangular major and minor panels opposing each other and each having a length. The length of the minor panel is less than the length of the major panel. The minor panel has a tab extending from an end thereof and separated from the minor panel by a tab crease line.Type: GrantFiled: July 26, 2000Date of Patent: December 11, 2001Assignee: Tetra Laval Holdings & Finance, SAInventor: Russell Stacy-Ryan

Patent number: 6182887Abstract: A package with an extended top panel has a front wall, a rear wall and a pair of parallel side walls. The package includes at least one top panel that seals to the package at a sealing region. A plane through the sealing region is spaced from a central vertical plane through the package. The extended top panel can extend to the rear wall at the sealing region. A second lesser top panel can extend from the rear wall and can seal with the extended front panel at an off-center top fin. A closure is accommodated on the top panel that has a cap having a diameter greater than the diameter of an aperture disposed through the extended top panel. A blank for the package is also disclosed herein. The package can include a handle attached to its top fin for carrying and displaying the package.Type: GrantFiled: April 16, 1999Date of Patent: February 6, 2001Assignee: Tetra Laval Holdings & Finance, SAInventors: Tommy Ljunström, Sheila Moss

Patent number: 6182888Abstract: The present invention is a carton having a forty-five degree off-set seal from its bottom and a blank therefor. The carton may have a square cross-section or an octagonal cross-section. The forty-five degree off-set seal allows for a stiffer package and material savings of up to seven percent over a traditional gable top carton. A method and apparatus for fabricating the forty-five degree off-set seal are also disclosed herein.Type: GrantFiled: September 11, 1998Date of Patent: February 6, 2001Assignee: Tetra Laval Holdings & Finance, SAInventor: Tommy Bo-Goran Ljungström

Patent number: 6024280Abstract: A gable-top vessel made from sheet material having a heat-sealable surface is disclosed. The closure has at least one abhesive layer disposed between and joining the inner surfaces of the first and second outer rib panels to define a pair of joined panels. In one embodiment, the abhesive is applied at least adjacent to the top edges of the outer rib panels which are joined. The abhesive layer can be a copolymer of ethylene and acrylic acid or vinyl alcohol. The abhesive layer substantially hermetically seals the joined panels together whicle reducing the force required to part the joined panels, compared to the force which would be required to part the joined panels if the same panels were heat-sealed directly together in the same sealing regions without the abhesive. A method of assembling a filled and sealed gable-top container is also disclosed.Type: GrantFiled: December 9, 1996Date of Patent: February 15, 2000Assignee: Tetra Laval Holdings & Finance, S AInventor: Harry Marovskis

Patent number: 6019279Abstract: A bottom end closure of a carton to be heat- and pressure-sealed has four substantially rectangular panels (P6, P7-P9, P12 and P14-P16) of which the panels (P7-P9 and P14-P16) are divided by score lines (S3, S7 and S13, S17) into inner, triangular sub-panels (P8 and P15) and outer triangular sub-panels (P7, P9 and P14, P16) and have central lugs formed by pairs of small, rectangular sub-panels (P10, P11 and P17, P18) providing for gas-tightness at the apices (A1 and A2) in the sealed closure. Score lines (S4, S6 and S14, S16) provide lines of weakness across the whole widths of the roots of the central lugs, so that the lugs, when each folded upon itself, can adjust to the orientation of an outwardly folded panel (P13) during tucking of the panel (P13) inwards of the lugs, which are sandwiched between the panels (6 and P13). In the blank, the lugs and the panels (P6 and P13) are so dimensioned that they can interdigitate with the corresponding lugs and panels of the bottoms of a row of identical blanks.Type: GrantFiled: August 25, 1997Date of Patent: February 1, 2000Assignee: Elopak Systems AgInventor: Andrzej Wieslaw Tywoniuk

Patent number: 6006984Abstract: A single generally rectangular blank which can be formed into a paperboard package. The four corners of the blank are trihedral. The blank is center folded. The width of a first portion of the blank, measured parallel to the centerfold, is greater than a second portion of the blank. The blank is sealed on the two sides adjacent the centerfold to form an open package, which is then filled. The side opposite the centerfold is then sealed to close the package, forming a parallelepiped container. The seals are fin seals. The fin seal opposite the centerfold of the blank overlaps the two seals adjacent the centerfold. The three fin seals are folded flat against the sides of the package. The package may be provided with an opening through the blank. A tab may be provided to completely cover and seal around the opening in the package. The tab includes a grip portion which, when pulled upwardly, lifts the tab away from around the opening in the package.Type: GrantFiled: December 9, 1997Date of Patent: December 28, 1999Inventors: Yun H.
