Abstract

An improved sleeve style beverage carton can be processed at or near peak production rates for carton blanks and without the need for manual removal of scrap from apertures in the carton blank. The increase in production rates and efficiency is principally obtained because the stripper pins on the stripper drum used in producing the carton blank consistently and reliably puncture and remove the scrap from apertures in the die cut carton blank thereby alleviating the need to slow or stop the machine for manual removal of the scrap. Advantageously, gusset holes which are die cut in the carton blank are preferably generally trapezoidal-shaped to provide for increased surface area of the gusset hole relative to prior art configurations. The trapezoidal-shaped larger gusset holes provide for a more consistent and reliable removal of the carton material scrap from the gusset hole during production of the blank.

Dependent claims

A tubular carton sleeve adapted to be formed into a carton for holding a plurality of beverage containers, the carton sleeve comprising:

a top wall;
a bottom wall spaced from the top wall;
a pair of spaced sidewalls foldably joined along respective sides thereof and extending between the top and bottom walls;
a plurality of major end flaps each of which is foldably joined to an end of one of the sidewalls;
wherein the major end flaps are adapted to be folded relative to the respective sidewall and cooperate together to form a pair of spaced end walls of the carton;
a plurality of minor end flaps each of which is foldably coupled to an end of one of the top and bottom walls;
wherein the minor end flaps are adapted to be folded relative to the respective top and bottom walls and juxtaposed to a face of the respective major end flap to form the end walls;
a plurality of gussets each of which is foldably joined to one of the major end flaps and an adjacent one of the minor end flaps;
and
a plurality of gusset holes each of which is defined at a juncture of one of the top and bottom walls, one of the sidewalls, one of the major end flaps, one of the minor end flaps and one of the gussets;
wherein each of the gusset holes is generally trapezoidal shaped to provide for increased surface area of the gusset hole and more reliable removal of carton material from the gusset hole during production of the carton sleeve.
