2 Claims.

This invention relates broadly to cartons, and more particularly to cartons of cardboard or light material which are collapsible.

An object of the present invention is to providey a carton that is especially adapted for use in shipping articles of furniture and more particularly to articles of furniture known in the trade as studio couches.

A further object of the invention is to provide a collapsible carton wherein the same defines a ypair of complemental telescoping sections, each of which is identically constructed; and wherein the structure of each is such as to provide reinforcements therefor at the places where the tying cord or the like will contact the carton structure as to cause wear thereon and the weakening thereof.

The invention, together with its objects and advantages will be thus understood from a study of the following description taken in connection with the accompanying drawings, wherein:

` Figure l is a perspective View of a complete carton, embodying the features of the present invention.

Fig. 2 is a sectional View of Fig. 1.

Fig. 3 is a blank from which each section of the carton is formed. y

Fig. 4 is an edge elevational viewof the blank.

Fig. 5 is a perspective View of one of the sections of the carton in set-up position.

Referring to the drawings by reference numerals, it will be seen that the improved carton comprises a pair of complemental telescoping sections 5. Each of the sections 5 is formed from a single blank of cardboard or other suitable material which is preferably rectangular and is I foldable on lines 6 6 to provide side walls l and bottom or central wall 8. It is also foldable on transverse lines 9 9 to provide end walls Ill. It will be seen that the side walls and the end walls I are hingedly connected to the bottom 8.

Also the blank is slit on angular lines II to provide tongues or projections E2 for each of the wings or corner aps I3 provided with the end walls IU. The wings I3 are formed by folding the blank on lines M constituting extensions of the fold lines 6. f

taken on the line 2-2 Also the blank inwardly from the fold lines S and immediately adjacent the respective opposite end of the fold lines 6 is slotted as at l5 to receive the tongues l2 when the walls I and ID are folded into right angular relationship to the bottom 8, as will be seen from a study of Fig. 5.

It will be seen thatv when the blank is folded to the position shown in Fig. 5, tongues I2 pass through the slots to the outer face of the bottom 8 and are then folded inwardly into overlapping engagement with the outer face of the bottom 8.

Thus the tongues I2 and slots I5 serve to hold the wings I3 of the ends I2 in right angular relationship to the ends HJ, and to hold the ends I l at right angles to the bottom 8.

When each of the sections are set up as shown in Fig. 5, the carton is ready for use. The contents of the carton are placed in one of the sections 5 whereupon the other section 5 is telescoped onto the first mentioned section to provide a lid therefor as clearly suggested in Fig. l.

When the sections are thus assembled in the telescoped relation, the tying cord I6 is then ap' plied thereto and in this connection it will be seen that the portions of the cord are trained across the respective oppositey ends of the carton, said parts of ythe cord are trained over the tabs l2 which latter then serve as a reinforcing means for the sections of the carton Acarton embodying the features of the presentinvention will be found to have many features of advantage over the present type of cardboard cartons, which latter are generally provided with slots in the side walls thereof, While the wings of the said walls which fold into overlapping engagement with the respective opposite ends of the side walls are usually provided -with tongues and engage the slots in the side walls, so that these tongues in no wise serve as a reinforcing means and wear surface for the carton as do the tongues I2 of the present invention.

It is thought that a clear understanding of the construction of a carton of this character will be had without a more detailed description.

Having thus described the invention what claimed is:

l. A carton formed from a blank of flexible material out and scored to provide a bottom and four side walls hingedly connected to the bottom, one pair of opposite side walls having integral corner flaps at opposite ends thereof lying against the inner surfaces of the other side walls, said corner flaps having downwardly extending prcjections inserted through slots provided at the juncture of the second named side walls and the bottom, said projections being of such length that they extend beyond said slots and have their outer end portions folded to overlie the outer face of said bottom.
