HERBERT B. BLISS, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO BLISS CON IAINERS,

INCL, OF NIAGARA FALLS, NEW YORK, A CORPORATION OF NEW YOR SHIPPING CASE.

Application filed June 13,

This invention relates to shipping cases constructed offibre board or equivalent material. It is the object of the present invention to afford a shipping case which is especially adapted for the transportation of heavy articles, such as automobile bumpers, etc. Articles of this kind present a very heavy endthrust on the end panels of the case. The ordinary fibre shipping case is ill adapted for shipping hardware of this kind, for while it has been possible to construct ends of plural thickness the seams have but one thickness and are easily broken.

It has been proposed to provide a shipping provide a shipping case that can be constructed of a single blank of fibre board or equivalent material and which results in no waste of material, and which further pro vides plural seams and plural joints to withstand the heavy end thrust of bumpers or other heavy hardware.

Referring to the drawings:

Fig, 1 is a plan View of the blank.

Fig. 2 shows the completed case.

Fig. 3 shows the blank partly folded up. Fig. 4 shows the same blank further folded u Fig. 5 is a section onthe line 5-5 of Fi 2.

Fi 6 is a section on the line 6-:6 of Fig. "Fig. 7 is asection on the line 77 of Fig. 6.

Figs. 8 and 9 are detail perspective showing how the seams are taken.

Fig. 10 is a fragmentary perspective showing how the case is sealed. Fig. 11 is a section on the line 1111 of Fig. 10. Referring to Fig. 1, the blank for a the ends of the blank.

therefrom by slots. Each of the supplemental end panels is provided with a corner flap each of the cover flaps is provided with a reinforcing flap 2", while these corner and reinforcing flaps j and i all line up along The end panels f' have sufiicient length preferably to extend out to the end edges of the blank.

The way the various elements are laid out V in the blank as shown in Fig. ,1, the width of the side walls is of course equal to the depth of the end wall when these dimensions are the same, and the layout is nicely balanced as in Fig. 1, so that the width of the sup- 7 plemental end panels 9 plus the corner flaps j is just equal to the depth of the main end panels 1; consequently there is no waste of material whatever. However as the vertical seams in the assembled case are the main ones necessary to be reinforced the length of the end panels are necessarily the width of the case so that the corner flaps will come into the desired position on the vertical seams.

Referring to Fig. 3, it will be seen how the parts are folded up. The side wall 0 is folded up with respect to the bottom wall a and the supplemental end panels 9 carried by the side wall 0 are turned in, as are also the corner flaps 7', attached to such supplemental end panels. The cover flap h, together with its reinforcing flap i can be turned in at the top.

' Next referring to Fig. 4, the other side wall 6 may be folded up and the supplemental end panel 9 folded in on the inside of the main end panel f or on the outside this is optional. As shown in Figs. 4 and 2, the main end panel is on the outside. The 100 against end thrust.

' the three end panels at each end stitched to gether on the ends of the case, as shown in Fig. 8.

The above arrangement provides three fibre end panels at each end of the case and provides two vertical wire-stitched seams at each vertical corner of the case. This obviously makes the case of extreme durability The cover flaps h which are folded in at the top under the cover Wings provide a double reinforcing structure at the top of the case near the ends. Each one of these flaps is provided with areinforcing flap 2' that is tucked in the inside ofthe case to further reinforce it whenever the dimensions permit; otherwise they lie flush. The cover wings are then folded over and are shown. in the drawings ofsuch width as to form a complete overlap, but this overlap can be reduced to save material. 4 The result is that the top of the case has two thicknesses of fibre board running the entire length, while at the ends where the strain is greatestfthere are three thicknesses of fibre board. These two cover wings may be stitched together by the insertion of the blade anvil, as shown in Fig. 10. The cover flaps themselves may be stitched together before the case is sealed, as shown in Fig. 4. However, this is simply optional with the shipper. Where they are stitched together as shown in Fig. 4, this adds two more seams which tend to resist any end thrust which is calculated to tear the three-end panels apart.

As stated the main end panel f may be on the outside. However, it may also be on the inside or in the middle. However, this main end panel may be long or short according to the dimensions of the box, in which event it is better to have it in the middle.

What I claim is: 1

1. In a shipping case for the purpose specified, a blank which is scored and slotted to provide bottom, side walls, cover wings and end panels provided with perpendicularly folded corner flaps, the same being arranged to be folded up and fastened togetheralong the entire flap to provide two Vertical seams at each vertical end corner.

2. A shipping ease for the purpose specified, having a single blank scored and slotted to provide a bottom wall, two side walls anda cover wing, a plurality of end panels with corner flaps, the same arranged to be folded up and fastened together to provide a plural ply end structure with the corner flaps folded perpendicularly and stitched to theside walls to form a reinforcing seam for the vertical end corners of the box. 1

3. A shipping case for the purpose specified, having a single blank scored and slotted to provide a bottom wall, two side walls, a cover wing and a plurality of end panels,

some of the end panels being provided with corner at the end of the. case.

4. In a shipping case for bumpers or other heavy hardware, a rectangular blank of relatively long and narrow proportions with substantially straight ends creased longitudinally and creased cross-wise near the ends, and slotted from such cross crease to the end in continuation of two of the center creases, whereby two side walls, a bottom wall, and cover wings, and at each end of the blank three end panels, two with one corner fiap each-are afforded, the said end panels arranged to overlap when the blank is folded up to provide a three ply end, the said three end panels being each united to the other to resist the breaking down of the box when thesame has been built up.

5. A fibre shipping case for the purpose specified, comprising a single blank slotted and scored to form two side walls, bottom wall, and a cover wing, each of the side and bottom walls provided with end extensions in the blank forming end panels and the blank adjacent the cover wing provided with end adjacent portions forming cover flaps, and both the cover flaps and some of the end pane ls provided with extended and scored portions forming respectively reinforcing flaps and corner flaps, the same all arranged to fold u and be fastened together to give a three- 'p y end structure with overlapping cover flaps at the top of the case near the ends, having tucked-in reinforcing flaps and to provide corner flaps which may be stitched to the adjoining side walls to provide additional reinforcement for the vertical corners at the ends of the case.

6. A fibre shipping case for the purpose specified, constructed of'a single blank comprising a blank structure slotted and scored 'to provide a bottom wall, two side walls and two cover wings, each of which is in the blank provided at each end with an adjacent" portion forming in the aggregate at each end three end panels, two of which are provided with corner flapsand two cover flaps, each of the latter being provided with a reinforcing I flap, the said elements arranged to be folded and fastened together to form a box having a three-ply end structure which may be fastened together, and the corner flaps turned in at right angles and engaging the side walls to provide double seams at each vertical cornor at each end of the case, and the cover the same arranged to be folded up to provide flaps turned in in overlapped relation while a plural ply end structure with the corners 10 the reinforcing flaps are tucked in. folded up perpendicularly and stitched to 7.
