COLLAPSIBLE OR KNOCKDOWN BOX.

Application filed May 31, 1913.

To all whom it may concern.

Be it known that I, Josnrn IV. Weiss, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Collapsible or Knockdown Boxes, of which the following is a specification.

This invention relates to collapsible boxes or cartons, more particularly to the type known as the slotted carton. A collapsible carton of this character is usually formed of an integral sheet of fibrous material having quadrilateral sides and end flaps which form closures for the ends of the box. The material of which the box is made is necessarily light in weight, and, therefore, is not sufliciently strong to resist shocks and wear incidental to its transportation from place to place while containing goods packed therein having any considerable weight. To overcome this difficulty due to the inherent flimsiness of construction of the collapsible slotted carton, I attach a cushioning rib, formed preferably of resilient material, to the sides adjacent to the junction of the sides and end flaps. This rib bears the brunt of the knocks, and owing to its resiliency, cushions the blow transmitted to the body of the box and thus prevents injury to the latter due to the sudden shock or blow. The rib may be formed of any suitable material calculated to produce the cushioning effect. I prefer, however, to form the same of fibrous material having the various portions thereof so disposed as to produce the necessary resiliency.

Referring to the drawing illustrating the preferred embodiments of this invention, Figure 1 is a perspective view of a slotted carton with my improved cushioning ribs applied thereto. Figs. 2, 3 and 1 are detail views of sections of various forms of ribs which may be used. Figs. 5, 6 and 7 illustrate in perspective fragments of other forms of ribs which may be used. Fig. 8 is a section showing a modified form of carton in which the end flaps may form continuations of said cushioning ribs. Fig. 9 is a fragmental perspective view of a modification in which cushioning ribs are also attached adjacent to the longitudinal edges as well as adjacent to the end edges of the box.

Referring particularly to Fig. 1, the carton or box may be formed of a single integral sheet of material having sides 10 and Specification of Letters Patent.

end flaps 11 forming closures for the ends of the box. -Adjacent to the junction of the sides and end flaps may be attached in any suitable manner as by staplin sewing or pasting, a resilient rib 12 preferably made of fibrous material so disposed as to obtain such resiliency or cushioning effect.

In Fig. 2,'I have illustrated a section of rib consisting of two walls 13 and 1 1 between which is disposed a sinuous or corrugated spacing member 15, the corrugations running lengthwise of the rib. To protect the raw edges, I have preferably pasted or otherwise attached, suitable finishing strips 16 'over the edges. These strips are preferably formed of tape, canvas or some other suitable strong, flexible material.

In the form of rib which is illustrated in cross section in Fig. 3, the same type of corrugated cushion is used as illustrated in Fig. 2. However, in this construction, the cushioning effect is increased by doubling the corrugated strip lengthwise upon itself,

thus the walls 17 and 18 corresponding to the walls 13 and 14 of Fig. 2 are made of greater width and together with the corrugated spacing member 19, are folded over at substantially their mid width as at point 20.

In the form illustrated in Fig. 4, the

outer walls 21 and 22- together with the corrugated spacing strip 23 are folded over at two points 23 and 24, thus bringing the edges 25closely toward each other. hen the rib is attached to the sides of the box, these edges 25 are entirely concealed.

In the modified construction illustrated in Fig. 5, the rib may be formed of a strip of material 26, having a sinuous section and attached to the sides of the box preferably at mid Width of the strip as by staples 27. By reason of a certain amount of resiliency in the material, resilient loops 28 and 29 are formed at the opposite edges which produce the cushioning effect.

In the form illustrated in Fig. 6, the re- I be composed of two walls and an intermediate corrugated spacing member as in the form illustrated in Fig. 2, may be suitably attached adjacent to the end edges of the sides of the box and have the flaps 36 formed therewith and extending therefrom. In this way, the end walls of the box forming the closure therefor are also resilient and further add to the strength of the box.

In the further modified form illustrated in Fig. 9, an added resilient rib 87 may be attached to the sides 10 adjacent to their meeting edges. This may be used as an added precaution in connection with boxes in which a large weight is to be carried located close to the mid-length of the box, in which case, when the box is thrown on its sides, the ribs 87 will support and cushion the intermediate portion of the box bearing the most weight.

It will be seen from the various forms of my invention above described, that I have provided a collapsible box which can receive considerable rough handling and jar without injuring the box itself and without disturbing the contents. Thus comparatively fragile matter may be sent in these boxes without breakage. Also, a heavy load can be carried by the boxes without danger of bursting the same as the edges are cushioned and when any blow or jar is sustained by the box, it will be taken up by the cushioning ribs without imparting the whole force to the body of the box. It will be noted also that these cushioning ribs have the added function of actually strengthening and bracing the box itself.

Having thus described my invention, I claim 1. A collapsible box formed of fibrous material having sides and end flaps extending therefrom forming closures for the ends of the box and a. flexible resilient cushioning rib formed entirely of fibrous material separate from the sides and disposed adjacent tothe unction of the sides and flaps, and means for attaching the cushioning ribs to the sides, all the members of the box continuing in attached relation to each other both when the box is set up or collapsed.

2. A collapsible box of fibrous material having sides and end flaps and a wave formed flexible resilient cushioning rib located adjacent the junction of the sides and flaps, said rib being separate from the sides and having a substantially fiat outer protecting surface, and means for attaching said cushioning rib to the sides, all the members of the box continuing in attached relation to each other both when the box is set up or collapsed.

3. A collapsible box of fibrous material comprising sides and end flaps, a resilient cushioning rib comprising a Wave formed member located at the exterior surface of the box adjacent to the junction of the sides and flaps, said rib being separate from the sides and having a substantially flat outer protecting surface, and means for attaching said cushioning rib to the sides, all the members of the box continuing in attached relation to each other when the box is set up or collapsed.

at. A collapsible box formed of fibrous material having side and end flaps extending therefrom forming closures for the ends of the box, and a wave formed flexible resilient cushioning rib located adjacent the edge of the box forming the junction of the sides and flaps, the waves of said rib extending lengthwise in the direction of said edge, and means for attaching said cushioning rib to the sides, all the members of the box continuing in attached relation to each other both when the box is set up or collapsed.

5. A collapsible box formed of fibrous material having side and end flaps extending therefrom forming closures for the ends of tie box, a wave formed flexible resilient cushioning rib located adjacent the edge of the box forming the junction of the sides and flaps and formed continuous thereabout, the waves of said rib extending in the dircction of said edge, and means for attaching said cushioning rib to the sides, all the members of the box continuing in attached relation to each other both when the box is set up or collapsed.

Signed at New York city, in the county of New York, and State of New York, this 29th day of May, A. D. 1913.
