Abstract
Abstract The present invention concerns a container such as that used to enclose beer bottles which container is made of cardboard in the usual manner. The carton may be sealed manually by the provision of carton side panels with tabs which are adapted to enter associated slots in underlying end panels and thereby secure said side panels to said end panels thus sealing the carton. The carton may also be sealed using an adhesive and presently used high-speed equipment and consequently the user need only maintain an inventory of one type of carton to cover both applications.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
253 words
A container comprising a base, end and side walls connected by hinge lines to one another; opposing pairs of end and side panels connected by hinge lines to the upper edges of respective end and side walls and extending substantially the length thereof, each end and side panel being adapted to fold toward its opposing respective end or side panel, said side panels being further adapted to overlie said end panels and co-act therewith to form the top wall with the longitudinal edges of said side panels substantially abutting; one of said end panels being provided with a pair of inwardly convergent slots closely straddling the centerline of said end panel, each said slot being oriented at an angle to the hinge line between said end panel and respective end wall; said end panel being further provided with a slit joined to the inner extremity of said slot and extending a very short distance toward the closest side wall and substantially parallel to said end wall hinge line; a pair of tabs, each tab disposed in the area of its respective side panel adapted to overlie said end panel containing said slots, said tabs being adapted to bend out of the plane of its respective side panel and enter said slots such that the tabs extend partially under a portion of the end panel between said slots thereby providing a strong frictional engagement at least a portion of an edge of said slits, whereby said side and end panels are mechanically secured together.
Claim 2
Dependent Claim
253 words
A container comprising a base, end and side walls connected by hinge lines to one another; opposing pairs of end and side panels connected by hinge lines to the upper edges of respective end and side walls and extending substantially the length thereof, each end and side panel being adapted to fold toward its opposing respective end or side panel, said side panels being further adapted to overlie said end panels and co-act therewith to form the top wall with the longitudinal edges of said side panels substantially abutting; one of said end panels being provided with a pair of inwardly convergent slots closely straddling the centerline of said end panel, each said slot being oriented at an angle to the hinge line between said end panel and respective end wall; said end panel being further provided with a slit joined to the inner extremity of said slot and extending a very short distance toward the closest side wall and substantially parallel to said end wall hinge line; a pair of tabs, each tab disposed in the area of its respective side panel adapted to overlie said end panel containing said slots, said tabs being adapted to bend out of the plane of its respective side panel and enter said slots such that the tabs extend partially under a portion of the end panel between said slots thereby providing a strong frictional engagement at least a portion of an edge of said slits, whereby said side and end panels are mechanically secured together.
Claim 3
Dependent Claim
100 words
A container as claimed in claim 1 wherein a pair of tabs is disposed on each side panel, each tab disposed in the area of its respective side panel adapted to overlie said end panels, said tabs being adapted to bend out of the plane of its respective side panel and enter said slots such that the tabs extend partially under a portion of the end panel adjacent the join of said slots and slits thereby engaging at least a portion of an edge of said slits, whereby said side and end panels are adapted to be mechanically secured together.
Claim 4
Dependent Claim
28 words
A container as claimed in claim 2 wherein at least one said end wall, associated with an end panel provided with said slots, is provided with a handhole.
Claim 5
Dependent Claim
41 words
A container as claimed in claim 1, 2 or 3 wherein each slot is oriented at an angle of from about 45° to about 135° to the hinge line between the end panel containing said slot and its associated end wall.
Claim 6
Dependent Claim
46 words
A container as claimed in claim 1, 2 or 3 wherein a line defining the base of the tab is oriented at an angle of from about 45° and 135° to a line including the hinge line between the side panel and its associated side wall.
Claim 7
Dependent Claim
32 words
A container as claimed in claim 1, 2 or 3 wherein each tab is defined in part by adjacent portions of the lateral and longitudinal free edges of the associated side panel.
Claim 8
Dependent Claim
71 words
A container as claimed in claim 1, 2 or 3 wherein the tab is generally rectangular in shape, two sides of which are defined by adjacent portions of the lateral and longitudinal free edges of the associated end panel, the base of the tab having a width marginally less than the length of the slot, the free end of the tab being tapered to assist the tab's insertion in the slot.
Claim 9
Dependent Claim
19 words
A container as claimed in claim 7 wherein the tab includes a third free side which side is arcuate.
Claim 10
Dependent Claim
33 words
A container as claimed in claim 1, 2 or 3 wherein said slit extends away from said slot such that the angle defined by the slot and the slit is an acute angle.
