NON-BUCKLING FOLDING BOX.

Specification of Letters Patent.

Patented Aug. 2'51, 191 8.

Application filed January 22, 1915. Serial No. 3,718.

Philadelphia,- in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Non-Buckling Folding Box, of which the following is a specification.

My invention relates to improvements in folding boxes and cartons, particularly such as are formed of a single blank of doublefaced corrugated board, which is scored along definite lines and creased to forin the hinges which join the walls.

A box of the above construction is foldable and collapsible and is, therefore, not suitable for packing and shipping breakables, such as bottles and the like. It was, therefore, customary to reinforce the box with an inner shell or cuff of the same character as that of the outer shell. Such a reinforcing shell or cuff adds some strength and rigidity to the box, butis not sufficient to prevent its yielding and buckling under pressure, and cannot be safely used for packing and shipping breakables. I

The chief object of my invention is to overcome the above defects by a novel form of hinge, adapted to brace and support the walls in such a. manner as to make the box non-buckling, so that it will withstand considerable pressure without crushing or damaging the contents.

With the above and related objects in view,

my invention comprises the construction, combination and the arrangement here1n after described, a preferred and modified. form of which are lllustrated 1n the accompanying drawings, and embraced within the scope of the appended claims.

. In the accompanying drawings, Figure 1 is a perspective view of an open box exposing its contents and partly broken away to show its improved interior; Fig. 2 is aplan view thereof without the covers; Fig. 3 is an elevation of a fragment of a blank adapted to be formed into a end with novel hinges; Fig. 1 is a plan view of the blank when folded and stitched along the lines of Fig. 3; Fig.5 is a-plan view of a box without its'covers and provided with an inner cuff constructed in accordance with my invention in a modified form; Fig. 6 is a view similar to Fig. 3, of a blank adapted to be formed into the cuff shown in Fig. Fig. 7 is a view similar to Fig. 4, of the blank folded along the lines of Fig. 6; Fig. 8 is a plan view f a box Without its outer cover and with a fragment of the inner cover. and provided with my novel hinges; Fig. 9 is a fragmentary elevation of the box of Fig. 3 partly broken away, and Fig. 10 is a perspective view of a hinge portion of the boxes shown in Figs. 1 and 8.

Referring now more particularly to Figs. 3, 4 and 10 of the drawing for a detail description of my invention, 1 represents a blank 'of double-faced corrugated board, 2 represents the lines along which it is scored,

3 represents stripsor tapes, preferably of a fiber having considerable tensile strength,

which strips are mounted on the blank with its edges 6 equidistant from the scored lines 2. The blank is then folded along the scored lines 2, as at 4 Fig. 4, and stitched by means of clips 5, and unfolded along the edges 6.

Referring now to Figs. 1 and 2, 7. represents the walls of the outer cuff, formed of a blank of double-faced corrugated board which is creased to form the hinges 8 joining the walls, the ends of the blank being joined by a strip or tape. 9, 10 represents the flaps which are integral with the walls, and 11 represents the hinges between said flaps and walls. As shown, the box is provided with an inner cuff comprising the hinges 1:2 diagonally across the hinges 8, and the walls 13 parallel with the walls 7. This inner cuff is formed of a blank of proper length of double-faced corrugated board, scored, creased, stitched and folded as shown in Figs. 3, 4 and 10, the ends of the blank being adapted to meet at 11 Fig. 2. An inner cover 15 is supported by the hinges 12 so as to be clear of the contents 16, and over said cover 15, the flaps 10 are folded to form an outer cover.

Mia

Fig. 5 represents a box similar in every respect to that shown in Figs. land 2, except that the hinges of its inner cuff are provided with sides'17, adapted to support the contents clear of the walls.

Referring now to Figs. 6 and 7 for a detail description of the inner cuff in connection with Fig. 5, 1 represents a blank of double-faced corrugated board, 2 represents double lines along which it is scored, and 3 represents the strips or tapes. The blank is creased along the lines 2 folded and stitched by means of the clips 5 and unfolded along the edges 6.

In Figs. 8 and 9 is illustrated a large box or packer comprising an outer shell 18, an

inner culf 19, compartments 20,,an inner cover 21, and flaps 22 adapted to foldover the inner cover to form an outer cover. The nner cuff 1s lnevery respect similar to that shown in connectionwith Figs. 1 and 2, ex-

cept that it isformed of alarger blank. The

outer shell is, as shown, provided with my novel hinges, which project oppositely to those of the inner cuff. The outer shell is formed of ablank of double-faced corru-- gated board, whichis first scored .as shown in Fig. 3, then horizontally and portions each equal in width to a strip 3 are cut out to form theflaps 22, and the central portion is then creased, stitched and foldedas shown inFigL A box or carton having an inner cuff provided with my novel hinges possesses great strength and rigidity and will not buckle, and such abox, with comparatively fragile articles, such as bottles, may be transported or shipped and subjected to usage and abuse without permitting articles therewithin to be damaged or broken. Each side wall is braced by the leaves of the adjacent hinges, the boxes are prevented from spreading or closing at the angles between the walls by the stitches joining the leaves, the hinges themselves form substantially rigid posts which will prevent the box from buckling.

For single articles it is sufficient to have the inner cufi only of mv improved construction.

as the inwardly projected hinges act as cushions forthe contents. A large packer with compartments for a number of articles should, preferably, be provided with my novel hinges on theoutside as well as on the inside, as in addition to the added strength andrigidity they act as cushions and protect the outer shell Having thus described my invention, it

.will be readily understood that variousv modifications thereof may be resorted to, withinthe scope of the appended'claim, without departing from the spirit or sacrificing any of its advantages.

What I claim as new and desire to protect by Letters Patent, is-

As an :improi'ement in boxes, a cuff of flexible material having radial inwardly projecting reinforcing joints or ribs, the same being formed of terminals of the longitudinal portions of the sides of the cuff infolded upon each other, said infolde-d portions being connected and positioned at the corners of the box.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

DAVID WEBER.
