Abstract

Abstract To provide a sheet feeding container device, a carton containing a pack of copy paper or similar sheet material is thrust into a tray-like metal cassette which is adapted to be fitted to the intake of a copying machine or the like. The cassette is provided with two blades which project into the carton and embrace the pack to maintain its lateral dimensional stability during feeding. The cassette and carton have interengaging projections which interlock the two members so that attempts to withdraw the carton from the cassette will destroy the carton.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 179 words
A self-contained, portable, unitary package, of generally rectangular parallelopiped configuration, for the introduction into a handling or treating machine of a flat pack of sheets, said package comprising a rigid shallow tray-like cassette having a bottom panel, a front wall, and oppositely disposed side walls with its rear end and top open, and receiving a flat non-rigid box-board carton of parallelopiped configuration having opposed top and bottom panels, and a rear end wall only, said carton containing said flat pack of sheets which are aligned longitudinally of said flat carton to be fed lengthwise therefrom, the side walls of said tray-like cassette embracing the side panels of said carton, and a flat blade projecting from said cassette interiorly of each side wall, occupying a vertical plane, and extending into the open forward end of the carton between a side panel of said carton and the adjacent side of said pack; the pair of blades closely but yieldingly embracing the side edges of the rectangular pack of sheets for insuring lateral dimensional stability during the longitudinal feeding of the sheets.
Claim 2
Dependent Claim 179 words
A self-contained, portable, unitary package, of generally rectangular parallelopiped configuration, for the introduction into a handling or treating machine of a flat pack of sheets, said package comprising a rigid shallow tray-like cassette having a bottom panel, a front wall, and oppositely disposed side walls with its rear end and top open, and receiving a flat non-rigid box-board carton of parallelopiped configuration having opposed top and bottom panels, and a rear end wall only, said carton containing said flat pack of sheets which are aligned longitudinally of said flat carton to be fed lengthwise therefrom, the side walls of said tray-like cassette embracing the side panels of said carton, and a flat blade projecting from said cassette interiorly of each side wall, occupying a vertical plane, and extending into the open forward end of the carton between a side panel of said carton and the adjacent side of said pack; the pair of blades closely but yieldingly embracing the side edges of the rectangular pack of sheets for insuring lateral dimensional stability during the longitudinal feeding of the sheets.
Claim 3
Dependent Claim 45 words
The device as set forth in claim 1 in which mutually interlocking means are provided in the cassette and the carton, whereby any attempt to pull the carton and the cassette apart will result in the mutilation or destruction of the carton, preventing reuse thereof.
Claim 4
Dependent Claim 154 words
A self-contained, portable, unitary package, of generally rectangular parallelopiped configuration, for the introduction into a handling or treating machine of a flat pack of sheets, said package comprising a rigid shallow tray-like cassette having its rear end and top open and receiving a flat non-rigid box-board carton containing said flat pack of sheets which are aligned longitudinally of said flat carton to be fed lengthwise therefrom, and mutually interlocking means on the cassette and the carton, whereby any attempt to pull the carton and the cassette apart will result in the mutilation or destruction of the carton, preventing reuse thereof, said interlocking means comprising a rigid tongue extending at a slight angle from the bottom of said cassette toward the surface of the bottom sheet of the pack, rather than across a side or an end of said pack, whereby upon such disruption of the carton, any remaining sheets therein will not be damaged.
Claim 5
Dependent Claim 154 words
A self-contained, portable, unitary package, of generally rectangular parallelopiped configuration, for the introduction into a handling or treating machine of a flat pack of sheets, said package comprising a rigid shallow tray-like cassette having its rear end and top open and receiving a flat non-rigid box-board carton containing said flat pack of sheets which are aligned longitudinally of said flat carton to be fed lengthwise therefrom, and mutually interlocking means on the cassette and the carton, whereby any attempt to pull the carton and the cassette apart will result in the mutilation or destruction of the carton, preventing reuse thereof, said interlocking means comprising a rigid tongue extending at a slight angle from the bottom of said cassette toward the surface of the bottom sheet of the pack, rather than across a side or an end of said pack, whereby upon such disruption of the carton, any remaining sheets therein will not be damaged.
Claim 6
Dependent Claim 142 words
As a subcombination, an article of manufacture comprising a rigid shallow, tray-like cassette for receiving and holding a flat carton of parallelopiped configuration, having opposed side panels, and containing a pack of sheets, which are aligned longitudinally of the flat carton, said cassette having a bottom panel, a front wall, and oppositely disposed side walls with its rear end and top open, the side walls of said tray-like cassette adapted to embrace the side panels of said carton, and a flat blade projecting from said cassette interiorly of each side wall, occupying a vertical plane, and adapted to extend into a carton between a side panel thereof and the adjacent side of a pack of sheets; the pair of blades thus adapted to closely embrace the side edges of the pack for insuring lateral dimensional stability during sequential removal of such sheets.
Claim 7
Dependent Claim 142 words
As a subcombination, an article of manufacture comprising a rigid shallow, tray-like cassette for receiving and holding a flat carton of parallelopiped configuration, having opposed side panels, and containing a pack of sheets, which are aligned longitudinally of the flat carton, said cassette having a bottom panel, a front wall, and oppositely disposed side walls with its rear end and top open, the side walls of said tray-like cassette adapted to embrace the side panels of said carton, and a flat blade projecting from said cassette interiorly of each side wall, occupying a vertical plane, and adapted to extend into a carton between a side panel thereof and the adjacent side of a pack of sheets; the pair of blades thus adapted to closely embrace the side edges of the pack for insuring lateral dimensional stability during sequential removal of such sheets.
Claim 8
Dependent Claim 56 words
The article as set forth in claim 4 in which each of said blades comprises an inverted U-shaped shank straddling one of the side walls of the cassette, the outer one of its arms rigidly secured to said side wall and the inner one spaced slightly from said side wall and terminating in the blade proper.
Claim 9
Dependent Claim 95 words
The article as set forth in claim 4, in which the front wall and those portions of the bottom and side walls adjacent the front or feed end of the pack of sheets are imperforate and thus impervious to air, and in which there is provided a small thin plate secured to the central portion of the rear surface of the froNt wall, against which the front end of the pack of sheets can abut, to leave a thin air space between the pack and said wall surface upon either side of said small plate.
