Fig. 10 is a perspective transverse sectional view through a box similar to that shown in Figs. 7 to 9, but being provided on its interior bottom faces with sheets of veneer, or the like, instead of elongated strips shown in Fig. '1.

Referring more particularly to Figs. 1 to 6 of the drawings, my improved container, as there s hown, comprises primarily four integral sides foldably connected together, the fourth' or top side being preferably constructed in the form of two cover flaps, each being integral and foldably connected to its adjacent side wall.

The sheet of material from which the integral flaps are made is shown secured to the inner face spaced distances, are the strips 2. Sheet I at predetermined positions vis transversely scored, as along

lines

3, 4, 5 and 6, these scorings being such as to permit sheet I to be folded along these lines to form the container sides 1 and 8, bottom 9, and top aps I0 and II. In assembling the container sheet I is folded around the end wall members I2, which are formed of suitable sheet material', which is reinforced by the marginal cleats I3. Cleats I3 are provided with notches I4 to receive the ends of reinforcing strips 2 when the sheet I1. is folded around these end wall members, as will be readily understood in Fig.- 1.

As noted in Fig. 2, the reinforcing strips 2 may be spaced from each other as desired, but at the

folding lines

3, 4, 5 and 6 the strips are preferably spaced only a slight distance apart, so that when at I in Fig. 2. Rigidly of sheet I, at suitably elongated reinforcing sheet the reinforcing strip 2 extends a slight distance (as indicated at I6) beyond the edge of sheet I. At its middle portion (or other location bined width of two reinforcing strips.'

condition from the factory to the consumer.

'Ihe purpose of this is seen in Fig. 4 to be the provision of overlapping surfaces along the meeting edges of the cover flaps, which greatly strengthens the cover of the container, and also leaves the top of the same flat, which is advantageous both from the standpoint of printing, writing or stenciling on the container cover as well as stacking the containers in piles.

To improve the reuse value of my containers I have provided means to facilitate the removal of lnails from the cover flaps, which nails if not removed would be a hazard to anyone Working with or around the container. This feature is shown in Fig. 6, in which a notch I8 is provided in each end of each of the strips 2, whichA are secured to the cover flaps I 0 and II. In nailing the'cover flaps to the panel I3 of the ends walls (or solid wood end walls if desired), the nails are driven rst through the' sheet of wall material of the cover flaps and then through the slots I8 and into the wood of cleats I3 or other end material. As will be readily understood, the head of the nail will straddle slot I8 so that it will bear against the material of the strip on each side of the slot, but will permit easy removal of the nail after the cover ap has been pried open, which would not be true if the nail were forced to form its own hole through strips 2 when being driven.

As shown in Fig. 1, the reinforcing strips 2 are so positioned on sheet I that in the finished box these strips will prevent the cans, cartons, or other packaged goods packed in the container from coming in contact with1 the outer sheet material, thereby avoiding the danger of same damaging the sheet material and at the 'same time adding rigidity and strength to the container. The integral foldable joints between the bottom,

sides and cover flaps eliminate the necessity of as four sides of the container may be made in one strip (see Fig. 2), and shipped in knocked down All the consumer has to do is assemble the end Wall members in position and fold the sheet' vI therearound, `and nail the side walls and bottom to the end wall members by nailing machinery now in common use. After the container is packed the top aps may also be nailed shut in nailing machines or by hand, as desired.

It is thusseen that I have provided acontainer that may be easily and quickly manufactured and not only pleasing in appearance but is readily adapted for reuse eitherv as a shipping container or as a grocers delivery box or the like.

'I'he modified form of container shown in Figs. 7, 8 and 9 comprises the two

side members

2,0 and 2|, to the former of which is integrally and foldably connected the Abottom flap 22 and top flap 23, While to said member 2| is integrally and foldably connected the bottom flap 24 and the top flap 25. Each of

bottom flaps

22 and 24 have elongated reinforcing strips 2 rigidly secured thereto, the'arrangement of the adjacent stripsat the meeting edges of the

bottom flaps

22 and 24, in the preferred form, being similar to that described above and shown in Fig. 4.

'Ihe end wall members 26 are each provided with an integral foldably connected upstanding iiap 21, which, in the preferred construction, are of a height suicient to enable them to meet at the center of the box when folded downwardly,

as suggested in Fig. 8. Suitable scoring lines 28 are provided between flaps 21 and end wall members 26 to facilitate their being folded inwardly during the operation of closing the container. Scorings along

lines

29 and 30 are also provided in each oi the side wall members and 2| with their integral flaps, to permit said flaps to be folded around the end wall members after the latter have been placed in proper position between the

side walls

20 and 2|. Notches I4 and I1 similar to those shown in Figs. I to 5 are also formed in the bottom of the bottom cleat of each of end wallsy 26 to receive reinforcing strips 2 of the bottom flaps.

End walls 26 in position between the side walls, and with the bottom flaps folded against the bottom of the end walls, are shown in Fig. 8, except that the near side wall is shown a slight distance away from the edge of the end walls for the sake of clearness. members 26 in the form of box shown inFlgs. '1 and 8 stand higher after assembly than do the top aps 23,- in order that the flaps 21 in an elongated box may meet at the middley without such waste of material as would be occasioned'in the so-called regular slotted type'bre or corrugated boardA boxes. As will be 4understood, in closing a container of the typeshown `in Figs. 7 to 9, the end aps 21, after the box is filled, will be pushed inwardly, as shown in Fig. 8, after which the

top flaps

23 and 25 may be pushed downwardly and attached to the end flaps 21 in the same manner and with the same standard and efficient equipment now used in closing the present slotted type -of shipping carton which is in general use, or they may be fastened into position by nailing into the cleats I3 of the end walls as desired.

A container similar to that shown in Figs. '7 to 9 is shown in Fig. 10, except that sheets viiila and 3l are substituted for the reinforcing strips 2 by being glued, stapled, or otherwise rigidly secured to the inner faces of the

bottom iiaps

22 and 24, in such manner that they in conjunction with the bottom flaps will produce an overlapping joint of the type shown in Fig. .4. `These reinforcing sheets 36a and 3l may be made of rotaryv cut lumber, fibre-board, corrugated fibre-board or other suitable reinforcing material as desired. It is thus seen that I have Vprovided a shipping container of unusually light weight but still of 5 great strength, and one which'is cheap to manufacture, pleasing in appearance, Y,canine shipped in knocked down condition, and may be easily and readily reused either for shipping purposes or for delivering or storing any material desired.
