HEAVY DUTY CONTAINER WITH INTEGRAL HANDLE United States Patent 3,310,219 HEAVY DUTY CONTAINER WITH INT EGRAL HANDLE Joseph J. Dingopolski, Chicago, Ill., assignor to Container Corporation of America, Chicago, Ill., a corporation of Delaware Filed June 2, 1965, Ser. No. 460,638 7 Claims. (Cl. 22934) This invention relates to paperboard shipping-containers, and more particularly to heavy duty containers having reinformed walls to provide special rigidity for increased stacking strength.

The invention comprehends an improved end wall construction which provides an integral handle arrangement for grasping and carrying the container.

ner posts and a recessed center portion providing a handle.

These and other objects of the invention will be apparent from an examination of the following description anddrawings, wherein:

FIGURE 1 is a perspective view of a container embodying features of the invention, with its cover shown in the closed position;

FIGURE 2 is a view similar to FIGURE 1, but with 'the'cover shown in an open position and with a portion of one of the end walls shown in a partially assembled condition;

FIGURE 3 is a longitudinaLvertical section taken on line 3-3 of FIGURE 1;

FIGURE 4 is a fragmentary, horizontal section'taken on line 44 of FIGURE 2; and

FIGURE 5'is'top plan view of the blank from which the container illustrated in the other views may be formed.

It will be understood that, for purposes of clarity, certain elementshave been intention-ally omitted from certain views where they arebelieved to be illustrated to better advantage in other views.

Referring now to the drawing fora' better understanding of the invention, and particularly to FIGURE 2, it

will be seen that the container includes a tray indicated front and rear side walls 12 and 14 and opposed end walls 16 hinged thereto and upstanding therefrom to form a box-like structure open at the top.

The cover of the container includes a generally rectangular fiat top wall 20, having the same dimensions as the bottom wall 10, which is hinged at its rear edge to the upper edge of the tray rear side wall 14. Hinged at its 'upper edge to the forward edge of cover top wall 20 is a cover front panel 22 which is of substantially the same dimensions as the tray front side wa.ll"12 and which is adapted to overlie the tray front side wall-when the cover is in closed condition. Hingedly attached tot-he opposite end edges of the cover front panel 22 are -a pair of closure flaps 24 which are preferably formed with rounded outer edges to facilitate closure of the cover in a manner hereinafter described.

Still referring to FIGURE 2, it will be seenthat the -front and rear side walls 12 and 14 of the tray are singleply, rectangular fiat walls; whereas, end walls 16 of the tray are multi-ply, reinforced Walls which have the dual pling, if desired (not shown). a great deal of additional rigidity for theend wall of the container and, when the cover is closed, the portions of 3,3 l 0,2 19 Patented Mar. 21, -1 967 ice function of providing addition stacking strength and at the same time providing handle means for grasping and lifting the container.

Each -of'the end walls 16 is divided into aLpair of end sections 30 located on'opposite side'of a recessed center section 32. The end walls of the tray each'include an outer shell having outer, top, and inner panels formed from an extension of the bottom wall of thetray, with the end wall outer panel 34 being hinged to the outer or'end edge of the tray bottom wall and having hinged to its upper edge a relatively narrow elongated top panel 36, which in turn has hinged to its opposite or inner edge the upper edge ofend wall inner panel 38. The end wall inner panel 38 may be formed at its free edge with a downwardly extending projection or locking tab 40 adapted to be received within a complimentary slot 42 formed in the bottom wall of the tray to secure the end wall in position. It will be understood that the outer and-inner panels of the end wall are spaced from each other a distance equal to the width of the en'd wall top panel 36.

The end wall outer panel has a central portion 44 cut wall portion 44 is displaced inwardly whenthe carton is erected so that horizontal section50 lies against that portion of the tray bottom wall which lies outwardly of the end wall inner panel and so that vertical section 52 lies against the outer face of the'end wallinner panel 38. Section 52-may be secured to the outer faceof the end wall inner panel in any manner, suchas by gluing or stapling (not shown), and also horizontal section 50 may be securedto the tray bottom wall 10 by gluing or sta- This construction affords the cover and the end wall top panelwhich overlie the 'recessed center section 32 of the end wall formahandle for grasping and lifting the carton.

The corners of the tray portion of the container are provided with internal corner posts 58 located within the end sections of each end wall'to add'rigidity to the container and provide additional stacking strength. These corner posts 58 are disposed inthe space between the inner and outer panels of the end walls and each are formed by an extension 60 hinged to the end of a side wall panel and divided by a pair-of double score lines 62 and 64 into first (outer), second (inner), and third (center) layers, 64, 66, and 68, respectively, which are folded as best seen in FIGURE 4 to provide a multi-ply corner post construction.

When the carton is erected the extensiond 60 are rolled or folded up in the manner shown, and, as the front and rear side walls are brought to the vertical position, the end walls-are wrapped or folded over the corner posts with the locking tabs 40 inserted in the bottom Wall slot 42 to form a'rigid' end wall construction.

As best seen in FIGURE 2 it will be noticed that there is aspace between the end wall outer panels and the corner posts outer portions which is adapted to receive the cover front closure flaps 24 when the cover is moved tothe closed position.

Thus it will be understood by this novel construction from a unitary blank'of foldable paperboard there is formed a rigid box-like structure with integral cover which has additional strength in the end walls-for stacking and Y which is provided with integral handlemeans by the novel end wall construction.
