Abstract
Abstract The entry of light into the interior of a beer carton through the handholes thereof is prevented by flaps, one of which is hingedly attached to the inner surface of each end panel above the upper margin of the handhole. The flaps are preferably wider than the handholes, extend downwardly below the lower margin of the handholes, and have a free lower edge. The flaps are preferably deflectable inwardly along a fold line opposite the upper margin of the handholes to permit entry of fingers around the upper margin of the handhole and between the inner surface of the end panel and the adjacent surface of the flap. Each end wall panel is preferably made of triple-folded material with the flap being cut out of the inside face of the material and the handhole being cut through the other two thicknesses.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
In a carton for carrying bottles or like articles and having at least one end panel with a handhole therein, a light shield for blocking the entry of light into the interior of said carton through said handhole, said light shield comprising a flap hingedly attached on an upper hinge line to the inner surface of said end panel a distance above the upper margin of said handhole, said flap having a lower free edge projecting downwardly below the lower margin of said handhole a distance sufficient to permit said free edge to be restrained against said inner surface by said articles, and said flap being deflectable inwardly opposite the upper margin of the handhole, and said upper hinge line being located a sufficient distance above the upper margin of the handhole to permit the entry of fingers around the upper margin of the handhole with the bent ends of the fingers projecting above said upper margin of the handhole and accommodated between the inner surface of the end panel and the adjacent surface of said flap, the free lower edge of said flaP being vertically shiftable during deflection.
Claim 2
Dependent Claim
189 words
In a carton for carrying bottles or like articles and having at least one end panel with a handhole therein, a light shield for blocking the entry of light into the interior of said carton through said handhole, said light shield comprising a flap hingedly attached on an upper hinge line to the inner surface of said end panel a distance above the upper margin of said handhole, said flap having a lower free edge projecting downwardly below the lower margin of said handhole a distance sufficient to permit said free edge to be restrained against said inner surface by said articles, and said flap being deflectable inwardly opposite the upper margin of the handhole, and said upper hinge line being located a sufficient distance above the upper margin of the handhole to permit the entry of fingers around the upper margin of the handhole with the bent ends of the fingers projecting above said upper margin of the handhole and accommodated between the inner surface of the end panel and the adjacent surface of said flap, the free lower edge of said flaP being vertically shiftable during deflection.
Claim 3
Dependent Claim
46 words
A carton construction as defined in claim 1 wherein the deflectable flap has a horizontal fold line positioned to facilitate deflection and shiftable during deflection from a position just below the upper margin of the handhole to a slightly elevated position approximately opposite said upper margin.
Claim 4
Dependent Claim
82 words
A carton construction as defined in claim 1 wherein said end panel is made of doubled-over material to provide inner and outer portions, said flap being cut out of the inner portion of said doubled-over material and said handhole being cut out of the outer portion, the upper margin of said flap being integral with the inner portion of said end panel and including a score line along the juncture between said upper margin of the flap and said inner panel portion.
Claim 5
Dependent Claim
129 words
A carton construction as defined in claim 1 wherein said end panel is made of doubled-over material to provide inner and outer portions, said flap being cut out of the inner portion of said doubled-over material leaving a surrounding relatively narrow marginal frame, and said handhole being cut out of the outer portion of said doubled-over material, the carton being a ''''Bliss''''-type carton having stitching flaps projecting from the end edges of the side and bottom walls, and said frame portion of the inner portion of the end panel being stitched to said stitching flaps at each end of the carton to provide an extra thickness, and said cut-out flap having its lower edge slideable within said marginal frame during deflection and substantially filling said marginal frame when undeflected.
