1 1 claim (Cl. ass-u) This invention relates to containers, particularly shipping cartons of the type shown in Beaman Patent NO. 2,214,220, dated September 10,

1940, wherein the end closures of the carton are secured to the'ends of the tubular body thereofbyjan interlocking flap construction and a retaining hoop therefor, and access is had to the.

contents of the carton by removing the hoop 'end closure at one end of said carton. The prin-' cipal object of the present invention is to provide an end closure construction of the above .type that will give ready access to the contents of the carton without removing the locking hoop or end closure from the carton. Other objects are to provide for closing the carton after accase is had thereto and to increase the strength and rigidity of the end closure construction. The invention consists in the improved carton bodyA,atopendclosureBandabottomend closure 0, all preferably made of corrugated board, fiberboard or other bendable sheet material. The tubular body A is divided intovside wall panels I by means of creases or scores 2 extending longitudinally thereof and is made from a flat blank whose ends are overlapped and permanently secured together by staples I or otherwise. Eachpanel I ofthetubularbodyhhas at each end a projecting flap 4 and a score or crease line 5 facilitating folding of said flap into and in the parts and combinations and arrange ments of parts hereinafter described and claimed. In the accompanying, drawings, which form part of this specification and wherein like' symbols refer to like parts wherever they occur,

Fig. 2 is a side elevational view of said carton, Fig. 3 is a top plan view of the carton, showbetween the latter and the body panels i.

proximity with the outside face of the said panel. Each of the end closures B and C comprises a closure member 8 of polygonal shape to fit the ends of the tubular body member A; and each side of said closure member has aprojecting flap 1 with a score or crease line a for facilitating bending of said flap, said flap having a continuation that is marked off by means of a score or crease line I and constitutes a tuck or looking-flap la. Each end closure member 8 is placed opposite one end of the tubular body A, its flaps I arebent over the folded body panel flaps l and the locking flaps Ia. are tucked beneathl said folded body panel flaps so as to lie- The flaps I of each end closure member 8 have ing the outside section orply ofthe end closure cut away and folded back to expose the access opening in the inside section or plyof said end closure and the plug cap for said opening.

The top end closure construction B also comprises an inside end closure member I3, preferably of corrugated board, fiberboard or other bendable sheet material. The inside end closure member I! is. located directly beneath, and in flatwise contact with the outside end closure member 6 of the top end closure construction B. The inside end closure member II is of po y onal shape to fit the end of the paneled tubular body I and extends between said end and the outside end closure i therefor. The sides of the insideend closure member .II have projecting flaps I 4- and score lines I! for facilitating bending of said flaps. The flaps are bent over the folded panel flaps] of the tubular body A and are interposed between said folded panel flaps and the folded flapsv'lyla of the outside end closure member I and are thus held against lateral movement relative to the latter and to said The inside'closure section or ply II of the top end closure construction B has a central circular hole It extending vertically therethrough hole by means of an annular member ll of fiberboard or like material which is stapled or otherwise permanently secured as at I, flatwise to the under side of said 'inside closure section.

The annular reinforcing member I! is disposed 7 provide a partially concentric to the opening It in the inside end closure member I35 and the opening in said annular reinforcing member is of smaller diameter than'the'opening in said inside closure .member, thereby forming an inwardly extendwise permanently secured together flatwise. The

upper disk ll of the plug cap D corresponding substantially to the diameter of the opening I in theinside closure member II, and the lower disk II is-of smaller diameter than the upper disk, whereby said upper disk fits in said opening and seats on the ledge ll therein and said lower disk fits within the annular reinforcing member II for said inside closure member.

The outside end closure member 6 of the top end closure construction B completely covers the inside end closure member If thereof and the removable plug cap Dfor the access opening it in the latter: and access is had to the contents of the container through said opening by partially cutting away the portion of said outside end closure member around said opening. Such line of cutting or separation is indicated on the outer face of the outside end closure member 6 of the top end closure construction B by a dotted, scored, or perforated arcuate line 22 disposed concentric to and of larger diameter than the access opening it in the inside end closure member II the extremities of such are being connected by line creases or scores 28 in said face of said outside end closure member. By this arrangement, access is had to the contents of the container by cutting through the outside end clos- V ure member 8 of the top end closure construcarcuate or horsehose line 22 and tion-B along the then swinging the along the score lines 28 which form a hinged connection between said'iiap and said member. Access may then be had to the container through the opening I in the inside end closure ll thereof by removing t P cap B, from said openthe outside 8,857,098 and is strengthened and stiifened around said ing, the 'marginal edge of said cap being nuns mm lifting m is msaid plug cap.

The hereinbefore described W has several important advantages, the double or, two- 7 ply top end closure construction B. together with the annular reinforcing member l'l, servu to increase strengthen the rigidity of. the aid ofjthe Access may be had to the contents of the carton without disturbing the interlocking flapconnections between the inside and outside closure members of the top end closure construction and the body A or the flap clamping hoop ll. merely by partially cutting away closuremember along the arcuate line 22 thereon, folding back the hinged cover flap 24 thus'fonned and then removing the plug cap D from the opening ll closed The desired quantity of material may be re- .moved from the carton, after which the plug cap D may be replaced and the hinged cover flap 24 folded down upon the latter.

Obviously, the inside closure member I I may bemade of metal or other hard material to pro-' vent cutting thereof whenthe outside closure member 8 is out along the arcuate line 22 and changes may be made in the connections be-' tween said closure members and the tubular two spaced parallel straight f flap "thus formed upwardly body without departing from the invention.

What we, claim is:

A shipping carton comprising a body and a' closure construction therefor, said closure construction comprising separate load sustaining inside and outside closure members; each having a rigid marginal connection with said body, said inside closure member having an opening therethrough, an annular member fixed to the inner face of said inside closure member around the opening therethrough and forming a reinforcement therefor and an inwardly projecting ledge at the lower end of said opening, and a separate detachable plug cap having a head portion mting in the opening in said'inside closure member substantially flush with the outer face there'- of and seating on said ledge and a plug portion fitting the opening in said annular member, said ing said plug cap from said opening through 5 the cut-away portion of said outside closure member.
