Patent number: 4723699Abstract: This relates to a clasp lock for interlocking two overlapping closure panels of a carton. The clasp lock is made adjustable to compensate for different sizes of articles being packaged in the same carton. In order to effect the adjustment of the lock between the closure panels, the primary locking tab is of a stepped height and the closure panel carrying the primary locking shoulders is cut so that the primary locking shoulders are also stepped with respect to the free edge of the associated closure panel. In the interlocking of the closure panel portions, the primary locking tab will automatically engage the proper primary locking shoulder in accordance with the objects which are being packaged within the carton.Type: GrantFiled: May 16, 1986Date of Patent: February 9, 1988Assignee: Federal Paper Board Co., Inc.Inventors: William M.

Patent number: 4702375Abstract: A wrap-around bottle carrier wherein the bottle heel cutouts at the ends of the carrier are spaced from the ends a greater distance than normal to increase the strength of the carrier at this area of stress. To permit this arrangement to be used, the shape of the outer or end cutouts is altered by connecting the top of the cutout to the vertical inner side portion of the cutout by a straight cut rather than by the usual curved cut. This allows the edges of the end cutouts to contact the bottles when the carrier is lifted even though, due to the change in dimensions of the end cutouts, the end cutouts are not symmetrically arranged with respect to the centerline of their associated bottles.Type: GrantFiled: November 1, 1985Date of Patent: October 27, 1987Assignee: Manville CorporationInventor: Jerry F. Wilson

Patent number: 4304329Abstract: An improved crown support carrier production blank and erected carrier for use with a plurality of beverage bottles. The production blank and the erected carrier are formed with a plurality of inclined upper side and end panels hingedly attached to a central panel and hingedly attached to a plurality of vertical lower side and end panels. A plurality of T-shaped corner glue tabs are formed in the corners of the production blank and are adhesively secured to the lower side and end panels when the production blank is erected to a completed carrier. The T-shaped glue tabs act as an exceptional reinforcing strip on the corners while their shape and placement are designed to round out or soften the corners rather than have sharp piercing corners typical in prior art carriers. Sunburst bottle receiving openings are positioned in the central panel along with at least one opening for use in carrying the package.Type: GrantFiled: September 2, 1980Date of Patent: December 8, 1981Assignee: Johns-Manville CorporationInventor: Earl J.
