Patent number: 5383835Abstract: A gas barrier folding carton formed from a unitary paperboard blank (10) having a gas impermeable polymer layer (52) such as EVOH, nylon, or foil extruded on or laminated to one surface of the blank, except for certain adhesive (56, 58) coated areas. Two opposite side edges of the blank are seamed to form a flattened tube (13) having top and bottom closure flaps (30, 34, 36, 38, 40). One of the major closure flaps (36) at each top and bottom container end is provided with spaced abhesive areas (58), with areas of the two minor closure flaps (34, 38) also provided with abhesive (56).

Patent number: 5081820Abstract: A method for applying an end plate to a container body includes applying a heated end blank made of deformable material to one end of the container body and creating a pressure difference between the two sides of the end blank to seal the edges of the end blank to the edges of the container body. The apparatus for applying an end plate to a container body includes a jacket having a chamber into which the container body can be fitted. A vacuum source is provided at one end of the jacket and a lid or clamping device is located at the opposite end of the jacket. The chamber into which the container body is fitted is not as deep as the container body so that when the container body is fitted into the chamber, the upper edges of the container body extend above the surface of the jacket. In that, the end blank can be applied to the container body and thereafter, the clamping device is used to clamp the end blank between the upper edge of the jacket and the clamping device.Type: GrantFiled: December 1, 1989Date of Patent: January 21, 1992Assignee: Aktiebolaget ProforInventor: Ulf Nedstedt

Patent number: 5024709Abstract: A method of forming a sift-proof seal for closure of a box having a plurality of folded flaps, the seal being formed by an adhesive strip pattern. The flaps are moved linearly toward a plurality of nozzles which extrude adhesive in a pattern of closely spaced adhesive strips. A flap having such an adhesive pattern is brought into contact with a second flap to compress the pattern of adhesive therebetween. The spacing between adjacent strips of adhesive is such that the folding of the flap causes merging of the adhesive to form a continuous strip of adhesive, thereby forming a box closure. The adhesive pattern is limited to a first outside edge of the first flap, with each remaining outside edges receiving a sift-proof continuous line of adhesive.Type: GrantFiled: January 22, 1990Date of Patent: June 18, 1991Assignee: Slautterback CorporationInventors: W.

Patent number: 4313899Abstract: Tearing, blistering, delamination and other defects in deep drawn plastic laminated paperboard containers are eliminated by adding controlled amounts of warmed moisture to the paperboard immediately prior to forming thereof. Water is heated to a desired temperature and is applied by in-line processing equipment to the unlaminated side of the paperboard which functions to both soften and paperboard and preheat the laminate. By heating both the male and female parts of a die press employed for forming the preheated, softened laminate into the container, preheating the laminate using warm water prior to forming and, continuously controlling the moisture added to the paperboard, the degree of stress imposed on the plastic layer of the laminate and the resulting defects in the formed container are significantly reduced.Type: GrantFiled: February 7, 1980Date of Patent: February 2, 1982Assignee: Champion International CorporationInventor: Paul Hain
