Abstract
Abstract A box-board carton for containing a pack of sheets to be fed to a copying machine or the like is adapted to be applied to a feeding cassette for insertion into the intake of such machine. The carton is provided with a tear strip and certain easy tear lines for stripping away certain forward portions thereof for access to the sheets during feeding. Tongues are struck from the bottom panel of the carton to provide openings for interlocking with projections on such a cassette, whereby the carton cannot be withdrawn from the caseette without destroying the carton.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
A cartOn for containing and dispensing a pack of sheets to be fed into a handling or treating machine, said carton being of the shape of a rectangular parallelopiped and having a top panel and a bottom panel, and opposite side wall panels, and front and rear end closures, a tear strip extending across the top panel nearer the forward end thereof, and easy tear lines extending from the ends of said tear strip forwardly of the carton along the upper forward edges of the side panels all the way to the forward ends of the said side panels and an easy tear line along the junction of the bottom panel and the front end closure, so that the forward end portion of the top panel and the attached elements of the front closure may be readily torn away to give free access to the front portions of a pack for feeding the sheets therefrom leaving practically the entire length of the side wall panels intact, for example, for cooperation with guide means for the fed sheets.
Claim 2
Dependent Claim
177 words
A cartOn for containing and dispensing a pack of sheets to be fed into a handling or treating machine, said carton being of the shape of a rectangular parallelopiped and having a top panel and a bottom panel, and opposite side wall panels, and front and rear end closures, a tear strip extending across the top panel nearer the forward end thereof, and easy tear lines extending from the ends of said tear strip forwardly of the carton along the upper forward edges of the side panels all the way to the forward ends of the said side panels and an easy tear line along the junction of the bottom panel and the front end closure, so that the forward end portion of the top panel and the attached elements of the front closure may be readily torn away to give free access to the front portions of a pack for feeding the sheets therefrom leaving practically the entire length of the side wall panels intact, for example, for cooperation with guide means for the fed sheets.
Claim 3
Dependent Claim
103 words
The carton as set forth in claim 1, in which a forward portion of the bottom panel is connected with the main portion thereof by a hinge line, but with its side margins free, and is initially connected with said front end closure by means of at least a portion of the said second mentioned easy tear line between the bottom panel and the said closure, whereby said forward portion of the bottom panel can be freed to be inclined upwardly with respect to the main part of the bottom panel to elevate the forward end of the back to facilitate sheet feeding.
Claim 4
Dependent Claim
158 words
A carton for containing and dispensing a pack of sheets to be fed into a handling or treating machine, said carton being of the shape of a rectangular parallelopiped and having a top panel and a bottom panel, and opposite side wall panels, and front and rear end closures, easy tear lines extending transversely across the top panel isolating a forward portion thereof, extending along the junction of said forward portion and the upper forward edges of the side panels, and extending along the junction of the bottom wall and the forward end closure, at least one cut made in said bottom panel for interlocking engagement with a cooperating sheet-fed facilitating device, and tear lines extending from said cut transversely across said bottom panel and said side wall panels, whereby attempted withdrawal of the carton from said device will result in ripping the forward portions of these panels from the remainder of the carton thus preventing reuse thereof.
