Abstract
Abstract This invention relates to a package of containers which are secured together by means of a plastic sleeve which is wrapped around the containers with the containers being normally arranged in two rows. The sleeve is open at its opposite ends. The package is provided with a cover, formed of paperboard, which overlies the upper ends of the containers and has finger openings therein alignable between four adjacent containers. The plastic sleeve also has finger openings aligned with the cover openings and the package is opened by tearing both the plastic sleeve and the cover toward the open ends of the sleeve. The cover is provided with diverging weakening lines extending from each of the openings to an adjacent end with the weakening lines defining a tear strip extending from each opening and which, when pulled toward the end of the package, functions as a lever and a guide with respect to the plastic material of the sleeve so as to rip away a portion of the sleeve and expose the containers of the package for easy removal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
333 words
A package comprising at least four containers arranged in at least two rows to define at least one opening between containers with each opening being defined by four adjacent containers, a cover overlying said containers, said cover having sides disposed parallel to said rows and ends disposed transverse to said rows, at least one finger receiving opening in said cover, said finger receiving opening being disposed between said cover sides and adjacent one of said cover ends in alignment with the opening between adjacent containers, a plastic wrapper encircling said containers and said cover in that direction generally defined by a line extending transversely of said container rows and generally parallel to said cover ends, said wrapper being in the form of a sleeve shrunk in place about the containers with the plastic of said wrapper having an orientation generally in the direction of said line and a tendency to tear only in a peripheral direction generally parallel to said line, said wrapper having remote edges generally at the ends of said rows, a finger receiving opening in said cover in alignment with said cover finger receiving opening, and said cover having easy opening means formed therein for tearing said wrapper generally longitudinally of said rows from the wrapper opening through an adjacent one of said wrapper edges to open said package, said easy opening means being in the form of diverging weakening lines formed in said cover and extending between said cover opening and an adjacent cover end and defining a combination lever and tear strip extending from said cover opening through said adjacent cover end in spaced relation to said cover sides with said tear strip being automatically operable as a lever and a guide to effect the tearing away of an end portion of that part of said wrapper overlying said cover from the associated wrapper opening generally transversely of said direction of plastic orientation to and through the adjacent wrapper edge to open said package and free containers therefrom.
Claim 2
Dependent Claim
333 words
A package comprising at least four containers arranged in at least two rows to define at least one opening between containers with each opening being defined by four adjacent containers, a cover overlying said containers, said cover having sides disposed parallel to said rows and ends disposed transverse to said rows, at least one finger receiving opening in said cover, said finger receiving opening being disposed between said cover sides and adjacent one of said cover ends in alignment with the opening between adjacent containers, a plastic wrapper encircling said containers and said cover in that direction generally defined by a line extending transversely of said container rows and generally parallel to said cover ends, said wrapper being in the form of a sleeve shrunk in place about the containers with the plastic of said wrapper having an orientation generally in the direction of said line and a tendency to tear only in a peripheral direction generally parallel to said line, said wrapper having remote edges generally at the ends of said rows, a finger receiving opening in said cover in alignment with said cover finger receiving opening, and said cover having easy opening means formed therein for tearing said wrapper generally longitudinally of said rows from the wrapper opening through an adjacent one of said wrapper edges to open said package, said easy opening means being in the form of diverging weakening lines formed in said cover and extending between said cover opening and an adjacent cover end and defining a combination lever and tear strip extending from said cover opening through said adjacent cover end in spaced relation to said cover sides with said tear strip being automatically operable as a lever and a guide to effect the tearing away of an end portion of that part of said wrapper overlying said cover from the associated wrapper opening generally transversely of said direction of plastic orientation to and through the adjacent wrapper edge to open said package and free containers therefrom.
Claim 3
Dependent Claim
12 words
The cover of claim 1 wherein said package is formed of paperboard.
Claim 4
Dependent Claim
37 words
The package of claim 1 wherein said weakening lines intersect said cover opening in transversely spaced relation to facilitate the removal of the tear strip in a tearing action with one''s finger placed in said cover opening.
