Abstract
Abstract A blank for a disposable sleeve for a beer case packaging structure having a reusable tray includes scoring outlining an openable closure for the packaging structure. The scoring may be provided by two closely spaced score lines, one formed through part of the thickness of the blank from one side and the other formed through the remainder of the thickness from the other side. The openable closure in the sleeve configuration is hinged about one lateral side edge of the top panel thereof and includes a tab at its free end positioned to coincide with a handhole in the tray so that the packaging structure may be temporarily reclosed.

Claim 1
Independent Claim
381 words
An integrally formed blank for a disposable cardboard sleeve comprising a rectangular center panel having first and second longitudinal side edges and first and second lateral side edges, a first rectangular side panel having a longitudinal side edge coextensive with one of said longitudinal side edges of said center panel and joined thereto by a first crease line, a scond rectangular side panel having a longitudinal side edge coextensive with the Other of said longitudinal side edges of said center panel and joined thereto by a second crease line, said first and second rectangular side panels each having first and second lateral side edges and a free longitudinal side edge, a first rectangular end panel having a longitudinal side edge coextensive with one of said lateral side edges of said center panel and joined thereto by a third crease line, a second rectangular end panel having a longitudinal side edge coextensive with the other of said lateral side edges of said center panel and joined thereto by a fourth crease line, each of said rectangular end panels having a free longitudinal side edge and free lateral side edges, a first pair of flaps each of which has a side edge coextensive with one lateral side edge of said first rectangular side panel and joined thereto through a fifth crease line, a second pair of flaps each of which has a side edge coextensive with one lateral side edge of said second rectangular side panel and joined thereto through a sixth crease line, the lateral width of said side panels and the lateral width of said end panels being substantially equal, and first and second laterally spaced apart scorings in said center panel and one of said end panels, each of said scorings extending from one lateral side edge of said center panel to the other, at least a substantial length of one of said scorings extending adjacent and substantially parallel to one longitudinal side edge of said center panel and at least a substantial length of the other of said scorings extending adjacent and substantially parallel to the other longitudinal side edge of said center panel, the scorings terminating in said one of said end panels and being joined together by a third scoring in said one of said end panels.
Claim 2
Dependent Claim
381 words
An integrally formed blank for a disposable cardboard sleeve comprising a rectangular center panel having first and second longitudinal side edges and first and second lateral side edges, a first rectangular side panel having a longitudinal side edge coextensive with one of said longitudinal side edges of said center panel and joined thereto by a first crease line, a scond rectangular side panel having a longitudinal side edge coextensive with the Other of said longitudinal side edges of said center panel and joined thereto by a second crease line, said first and second rectangular side panels each having first and second lateral side edges and a free longitudinal side edge, a first rectangular end panel having a longitudinal side edge coextensive with one of said lateral side edges of said center panel and joined thereto by a third crease line, a second rectangular end panel having a longitudinal side edge coextensive with the other of said lateral side edges of said center panel and joined thereto by a fourth crease line, each of said rectangular end panels having a free longitudinal side edge and free lateral side edges, a first pair of flaps each of which has a side edge coextensive with one lateral side edge of said first rectangular side panel and joined thereto through a fifth crease line, a second pair of flaps each of which has a side edge coextensive with one lateral side edge of said second rectangular side panel and joined thereto through a sixth crease line, the lateral width of said side panels and the lateral width of said end panels being substantially equal, and first and second laterally spaced apart scorings in said center panel and one of said end panels, each of said scorings extending from one lateral side edge of said center panel to the other, at least a substantial length of one of said scorings extending adjacent and substantially parallel to one longitudinal side edge of said center panel and at least a substantial length of the other of said scorings extending adjacent and substantially parallel to the other longitudinal side edge of said center panel, the scorings terminating in said one of said end panels and being joined together by a third scoring in said one of said end panels.
Claim 3
Dependent Claim
330 words
The blank of claim 1 wherein said first scoring is constituted by a first pair of score lines in said center panel extending in closely spaced-apart relation from said one lateral side edge of said center panel substantially parallel and adjacent to but spaced from one of said longitudinal side edges of said center panel to a first position spaced longitudinally inwardly from said other lateral side edge of said center panel, and said second scoring is constituted by a second pair of score lines in said center panel extending in closely spaced-apart relation from said one lateral side edge of said center panel substantially parallel and adjacent to but spaced from the other of said longitudinal side edges of said center panel to a second position spaced longitudinally inwardly from said other lateral side edge of said center panel, said first and second longitudinally inwardly spaced positions being substantially the same longitudinal distance from said other lateral side edge, said first pair of score lines continuing from said first position in spaced-apart parallel relation angularly away from said one longitudinal side edge, of said center panel, across the crease at the join of said center panel and said one end panel at said other lateral side edge of said center panel, and terminating in one end of a third score line constituting said third scoring, said second pair of score lines continuing from said second position in spaced-apart parallel relation angularly away from said other longitudinal side edge of said center panel, across the crease at the join of said center panel and said one end panel at said other lateral side edge of said center panel, and terminating in the other end of said third score line, each of said first and second pairs of score lines being provided with one score line of the pair being formed from above said center panel and the other score line of the pair being formed from below said center panel.
Claim 4
Dependent Claim
70 words
The blank of claim 2 wherein said third score line includes a portion substantially parallel to said one longitudinal edge of said one end panel spaced from the ends of said first and second pair of score lines towards the free longitudinal edge of said one end paneL and portions joining the ends of said parallel portion thereof and the ends of said first and second pairs of score lines.
Claim 5
Dependent Claim
94 words
The blank of claim 2 formed of a laminate of at least two layers of thin cardboard and wherein each of said first and second pairs of score lines is provided with one score line of the pair being formed from above said center panel through the thickness of at least one but not all of said layers and the other score line of the pair is formed from below said center panel through the thickness of the remainder of said layers, whereby the score lines terminate at the interface of two adjacent layers.
Claim 6
Dependent Claim
46 words
The blank of claim 2 wherein the members of said pairs of score lines in the portion extending angularly away from said longitudinal side edges are spaced apart a distance less than the distance between the remainder of the length of each pair of score lines.
Claim 7
Dependent Claim
