Abstract
Abstract A sleeve blank for holding at least one container of the type having a closure portion which protrudes outwardly beyond the external surface of the body thereof. The sleeve blank includes a top panel, two opposing downwardly foldable side panels extending from the top panel, a bottom panel extending from one of the side panels and an inwardly foldable locking panel extending from the other side panel for locking engagement with the bottom panel. According to the present invention, the two side panels are each provided with at least one first die cut arranged adjacent and extending parallel to at least one of the folded edges thereof. The side panels also have at least one second die cut arranged to terminate at and extending perpendicular to the first die cut. The die cuts on the two side panels are arranged in opposing relationship on the sleeve blank so as to permit the panels to expand at the points surrounding the closure portion of a container.

Claim 1
Independent Claim
219 words
In a sleeve blank for forming a sleeve pack, suitable for holding at least one container that has a body portion and a closure portion on at least one end thereof, which closure portion protrudes outwardly beyond the external surface of said body portion, said sleeve blank comprising a top panel; two opposing downwardly foldable side panels extending from said top panel through respective continuous folded edges; a bottom panel extending from one of the side panels and inwardly foldable beneath said container; and an inwardly foldable locking panel extending from the other side panel for locking engagement with the bottom panel, the improvement wherein said two side panels have first and second die cuts only at least one opposing first die cut in each side panel arranged adjacent, and extEnding parallel to, at least one of the continuous folded edges of said side panels and at least one opposing second die cut arranged to terminate at, and extending in the direction away from said adjacent continuous folded edge and perpendicular to, said first die cut, whereby said first and second die cuts permit said two side panels to expand at the points surrounding said closure portion of said container thereby to engage said container and whereby the sleeve pack presents smooth side surfaces to an adjacent sleeve pack.
Claim 2
Dependent Claim
219 words
In a sleeve blank for forming a sleeve pack, suitable for holding at least one container that has a body portion and a closure portion on at least one end thereof, which closure portion protrudes outwardly beyond the external surface of said body portion, said sleeve blank comprising a top panel; two opposing downwardly foldable side panels extending from said top panel through respective continuous folded edges; a bottom panel extending from one of the side panels and inwardly foldable beneath said container; and an inwardly foldable locking panel extending from the other side panel for locking engagement with the bottom panel, the improvement wherein said two side panels have first and second die cuts only at least one opposing first die cut in each side panel arranged adjacent, and extEnding parallel to, at least one of the continuous folded edges of said side panels and at least one opposing second die cut arranged to terminate at, and extending in the direction away from said adjacent continuous folded edge and perpendicular to, said first die cut, whereby said first and second die cuts permit said two side panels to expand at the points surrounding said closure portion of said container thereby to engage said container and whereby the sleeve pack presents smooth side surfaces to an adjacent sleeve pack.
