ONE-PIECE CONTAINER Filed June 11, 1934 awvcmbon f/o wm'd l7. Zfmida/l Patented Nov. 12, 1935 UNITEDSTATES I ONE-PIECE comma Howard D. Randall, Cincinnati, Ohio, assignmto The Randall Company Duration Ohio Cincinnatii Ohio, acor- Application June 11, 1034, Serial No. 130,009 3 Claims. (01. 229-51) This invention relates to a one-piece container such as may be used for packaging a group of sheets, for example sheets of copy paper or the like for use upon typewriters and similar machines.

An object of the invention is to provide a one piece container of the above stated character, which may conveniently and easily be opened in such a manner as to provide for easy removal of the sheets contained therein while at the same tim preserving the sheet-protective function or character of the container.

A further object of the. invention is to reduce the cost of packaging various kinds of sheets which are sold or delivered as relativelysmall groups, and which, in many caste, the sheets ace removed periodically until the container is empty.

The foregoing and other objects are attained by the means cicscriheti'herein and disclosed in the accompanying drawing, in which:

to, a completely closed ation, to render the sheets in the container easily accessible by complete removal of the front end wall, its associated flap 6, and part of the top member 5, which elements form the end closure means of the container. The treatment re- 5 Ierred to comprises striking or cutting through the material of the top member 5, at a distance from the adjacent score lines S, to provide a pull tab IS in the plane of the top wall member and extending in a direction rearwardly of said top 10 wall member, the length of the tab being determined. by the dead ends I l of the out which forms the tab. Said dead ends it are spaced considerably irom'the adacent scores S, for a reason to be explained later. From the points I t; and 15 09, which are the comers of thefront end of the top member 5, the material of the top is iiitermittentlv punched or otherwise weeireneol along lines it and Ziyvzhich lines converge toward the rear of the container and which; ii exttended, would meet at a point, such as P, noon the tale it. The convergent lines, however, ehoi approximately antheoieocl critic ll of the too out upon the top member With the construction alcove described, the user upon eclesirhio, to open the container and coining access to the contehts'thereoi, merely grasps the tab it and pulls it forwardly sum cicntlt to tear the material oi the top member. along the weakened portions iii and it, where upon the entire enol closime constituted of the removable top section 22, talc it, end well ii, anti flap ii, become disassocieterl completely item the container. The removal oi. the top section 2%] provides a convenient upper recess in the top member whereby the users fingers wiii have easy access to the iorwarcl cools oi the sheets within the container. The opening time provided at the front end of the container ce ample and unohstrocteol for removal of she i therefrom, and the opened cohtwmer will not mio'iitiv or marred in. the end thereoi. rte-Will reooiiiv be evloloiit, Wail ii, ii, i5) and. it may to height to become which case the of he cont rili be reduced to a minimmm, out the treat eio= more will ctili periorm on above set forth. it is to he understood that various tions and changes in the streetiirai oietoiic oi device may he made, within the scope of the are oencleol claims, without departing from the oi the invention,

What is claimed is:

I walls, a front wall, and a rear wall, and a front end closure means for the container comprising the front wall and. a flap which are constituted of an extension of the forward end of the top wall member, the line of juncture of the front wall and the top wall member forming opposed forward corners of the container, a tab struck from the material oi the top wall member at a distance from said line of juncture and providing a cut with'dead ends terminating at a distance from said line of juncture but forwardly of the center of the tab, each of the dead ends of the out being connected with the aforesaid opposed forward corners of the container by a materialweakening cut, whereby a forward manual pulling of the tab results in complete removal of the tab, the front wall, the flap connected to said front wall, and that portion of the top wall member which is forwardlt of the material-weakening cuts, so as to provide an unobstructed access opening at both the top and'the adjacent front ends of the container, said material-weakening cuts being inwardly convergent toward the rear of the container but falling short of actual meeting at the dead ends of the tab cut.

2. As a new article of manufacture, a onepiece container blank comprising a top wall member having front, rear, and side limits determined by score lines arranged in rectangular forfro mation, front, rear, and side wall members extending outwardly from the corresponding limits of said large top member, and flaps extending outwardly of each of said front, rear, and side wall members, the flaps which extend from the side wall members being of such width as to provide a bottom for the container when folded inwardly and toward the top wall member, and a front end closure means including the front wall member and its associated flap, a tab struck from the material of the top wall member at 9.

distance from the score line which determines the front fiapand providing a cut with dead ends terminating at a lesser distance from the last i mentioned score line, each of the dead ends of the out being connected with the forward corners of the rectangular top wall member by a material-weakening cut, whereby a forward manual pulling of the tab results in complete removal of the tab, the front wall, the flap, and that portion of the top wall member which is forwardly of the material-weakening cuts, as and for the purposes described.

piece container blank comprising a top wall member having front, rear, and side limits determined by score lines applied to the material of the blank in a substantially rectangular formation, front, rear, and side walls extending outwardly from the corresponding score lines which determine the limits of the top wall member as stated above, flaps extending outwardly of each of said walls, the flaps which extend from the side walls of the container blank being of such width as to provide a bottom for the container when folded inwardly and toward the top wall member, and a front end closure means including the front wall, the front flap, and a tab struck from the material of the top wall member at a distance from the score line which determines the front wall, sald tab being formed by a cut with dead ends terminating at a lesser distance from the last mentioned score line, each of the dead ends of the out being connected, by a material-weakening cut, with the score lines which distinguish the side walls from theside edges of the top wall member, whereby a forward manual pulling of the tab results incomplete HOWARD n.
