Abstract
A box with an integral hinged lid is formed from a blank, typically by folding the blank about an open-ended inner wrapper containing the article to be packaged. Prior to opening of the package the lid is joined to the front of the package by integral connecting member which are easily broken. The lid is defined, in part, by lateral tabs of triangular shape and a narrow tab of trapezoidal shape which, during folding of the blank, serve to fold the open end of the inner wrapper.
Claims15
In a box having a generally cuboid shape and a hinged lid, being articulated to the rear side of the box and having a wall which covers a first end of the box in the closed condition of the lid, said covering wall being adhesively secured to a pair of underlying and oppositely disposed lateral end tabs, said lid further having a pair of oppositely disposed side walls which are connected to said end tabs, said lid also including a front wall and a rear wall, the lid front wall being connected to said covering wall and the lid rear wall being connected to the rear side of the box, the box further including an inner wrapper received in the box and folded about the contents of the box, the inner wrapper generally conforming to the shape of the box interior and having a pair of oppositely disposed lateral side edge portions which are folded inwardly toward one another, the improvement comprising:
- a tab extending from said lid rear wall, said tab extension having three exposed edges and extending generally transversely with respect to said lid rear wall in the direction of said lid front wall;
- said lateral end tabs generally having a triangular shape;
- said lid front and side walls being respectively connected to the box front and side walls by narrow strips of material which bridge shear lines between adjacent edges of said connected walls;
- said inner wrapper having a first end flap which is folded over said lateral side edge portions and a second end flap which is folded inwardly toward and over said inner wrapper first end flap, said second end flap having a width in the direction of the fold line of the first end flap which is less than the width of the box between the front and rear sides thereof, said tab extension of said lid rear wall extending toward the fold line of the inner wrapper second end flap and in part overlapping the inner wrapper first end flap, the width of said tab extension being selected such that said inner wrapper second end flap does not overlie said tab extension;
- whereby the inner wrapper when completely folded is free relative to the box lid.
A flat blank for use in the formation of a cigarette package having a generally cuboid shape, the cigarettes being enclosed within an inner wrapper having an open upper end extending above the cigarettes, said blank adapted to be folded about the inner wrapper to close said upper end and to form a lid thereover without capturing the inner wrapper in folds of the lid, said blank comprising:
- a container defining first section and lid defining second sections, said first section comprising rectangularly shaped portions which define package front, bottom and rear panels which are respectively interconnected by fold lines, said rectangularly shaped portions each having side wall defining tabs extending therefrom, said side wall defining tabs being connected to their associated portions by means of further fold lines, a first of said lid defining sections comprising a lid rear wall defining portion which is connected to said portion of said first section which defines the package rear panel by means of a hinge line, a pair of oppositely disposed lid inner side wall defining portions being connected to said rear wall defining portion by fold lines and being separated from adjacent side wall defining tab extensions of said package rear panel defining portion, another of said blank second sections comprising a lid front wall defining portion having a pair of oppositely disposed lid outer side wall defining portions extending therefrom, a lid cover wall defining portion extending from said lid front wall defining portion and being connected thereto by a fold line, a triangularly shaped lateral end tab extending from each of said lid outer side wall defining portions in the same direction as said lid cover wall defining portion, a cut defining the ends of said first section front panel defining portion and the side wall defining tabs connected thereto which are disposed oppositely with respect to said bottom panel defining portion, said cut being bridged by narrow connecting regions between respective of said front panel defining portion and said lid front wall defining portion and between said lid outer side wall defining portions and respective adjacent package side wall defining tabs, and a further tab of narrow width extending from said lid rear wall defining portion, said further tab having three free sides and being connected to said lid rear wall defining portion by a fold line, the width of said further tab being selected such that said inner wrapper when folded does not overlie said further tab.
