Patent number: 5201412Abstract: A paperboard clip-type carrier especially suited for carrying beverage cans. The top panel comprises overlapped inner and outer top panel flaps which provide double thickness in the handle area. Support edges in reinforcement sections connected to the bottom panel and the side panels engage the underside of the can chimes to support them, and stress relief score lines are provided to distribute stresses from the support edges through the reinforcement sections. The side panel has cutouts through which the can chimes can protrude, allowing the side panels to be positioned tightly against the cans to increase the strength of the carrier.Type: GrantFiled: April 30, 1992Date of Patent: April 13, 1993Assignee: Riverwood Natural Resources CorporationInventors: Richard L. Schuster, Leonard M. Cooper

Patent number: 5107986Abstract: Integral retaining means in an open-ended wrap-around carrier for preventing the spaced bottom portions of articles such as tapered tubs from engaging each other and escaping the carrier through the open end. The bottom panel is comprised of inner and outer mechanically connected flaps. The outer bottom panel flap contains a retainer flap at each end connected along a fold line overlying the inner edge of an opening in the inner bottom panel flap. The retainer flaps extend up into the interior of the carrier through the openings in the inner bottom panel flap, and include spaced converging fold lines which create angled side walls for engaging the bottom portions of the articles.Type: GrantFiled: November 12, 1991Date of Patent: April 28, 1992Assignee: Riverwood International CorporationInventor: Leonard M. Cooper

Patent number: 5002186Abstract: A paperboard carrier for beverage cans the bottom of which tend to be deformed when subjected to sharp blows. The panel adjacent the can bottoms is formed of two sheets in face-to-face engagement. The interior face of the inner sheet contains a number of raised embossed portions against which the can bottoms abut. The embossed portions, which may be comprised of spaced embossed protrusions of circular or other shape, effectively increase the cushioning effect of the sheet and, in conjunction with the other sheet of the panel, protect the can bottom against damage. The embossed portions are arranged so as to contact the circumferential rims normally provided at the bottom of beverage cans.Type: GrantFiled: April 16, 1990Date of Patent: March 26, 1991Assignee: Manville CorporationInventor: Leonard M. Cooper

Patent number: 4860943Abstract: A carton having a bottom panel comprised of two overlapping flaps. The outer flap has a primary male tab engaging a primary female locking edge in the inner flap, while the inner flap has a secondary male locking tab engaging a secondary female locking opening in the outer flap. The secondary locking tab is connected to the carbon along a fold line coinciding with the fold line connecting the inner flap to the adjacent side panel, allowing a large secondary locking tab to be used even though the bottom panel is narrow. The outer and inner flaps are able to overlap across substantially the full width of the flaps to form a bottom panel of double thickness.Type: GrantFiled: April 29, 1988Date of Patent: August 29, 1989Assignee: Manville CorporationInventor: Leonard M. Cooper

Patent number: 4852731Abstract: A sling-bottom carrier adapted to carry long-necked beverage bottles. The carrier has an upper panel and a center partition with transverse cell-forming partitions. The center partition has a handle opening near the top and the top panel has a handle access opening overlying the center partition. A flap covering the access opening is folded down in use to allow a user to reach the handle opening. The front, back, bottom and top panels are formed from a continuous integral sheet, and the center partition sections of the carrier blank are on the same side of the sheet, thereby minimizing the amount of material needed. A reinforcing section makes the handle area in the center partition of triple thickness.Type: GrantFiled: October 13, 1988Date of Patent: August 1, 1989Assignee: Manville CorporationInventor: Leonard M. Cooper

Patent number: 4449633Abstract: A new and improved ovenable paperboard carton for use in a microwave and conventional oven is disclosed. The improved carton comprises a bottom tray having a plurality of side panels with gusset panels attached thereto and combines the bottom tray with a new and improved upper lid which has a central top panel and a plurality of side panels hingedly attached thereto. The upper lid contains a pair of strategically placed reverse cuts which form a tear-off portion for the carton. The tear-off portion is designed to provide corner reinforcement to the package. When the tear-off portion is removed from the upper lid, a pair of structurally supporting channels are formed along opposite edges of the carton to add stability, with the corner reinforcement, to the package upon removal of the lid. The upper lid is adhesively secured to the bottom tray to further enhance the rigidity of the package.Type: GrantFiled: December 17, 1979Date of Patent: May 22, 1984Assignee: Manville Service CorporationInventors: Harold D.
