SHIPPING CONTAINERS Filed Aug. 7, 1953 ZmMHa d. DEEREN United States Patent O SHIPPING CONTAINERS Thomas J. Deeren, Toledo, Ohio, assignor to Owens- Illinois Glass Company, a corporation of Ohio Application August 7, 1953, Serial No. 372,925

1 Claim. (Cl. 229-14) The present invention is a shipping container and more particularly a container formed of paperboard or other suitable material and intended for use in shipping glass bottles, jlars, and like fragile articles which require cush i'oning against shock arising from rough handling etc.

An object of my invention is the provision of a shipping container composed of inner and outer paperboard carltons of non-circular tubular form so relatively prosition'ed that the side walls of a packaged Iarticle, a bottle for example, will be spaced a substantial distance inwardly from the outer wall of the shipping container and therefore less subject to breakage incident to any rough handling and even crushing, to a limited degree, lof the sides of the outer carton.

A further object is the provision of a shipping container, as just stated, wherein both cartons are generally rectangular in form `and the inner carton is placed and securely held in a diagonal position within the outer carton.

Another object is the provision of a shipping container of the above character in which selected ilaps at the ends of the outer carton function to hold the two cartons Iagainst -relative shifting about their common longitudinal aims.

Other objects will be in part apparent and in part pointed out hereinafter.

In the drawings:

Fig. 1 is a plan view of `the blank `from which the outer carton is formed;

Fig. 2 is a perspective view partly in section showing the inner and outer cartons at an intermediate stage of assembly;

Fig. 3 is a top plan view of my shipping container prior to closing of the cover aps of the outer carton; and

Fig. 4 is a sectional View taken along the line 4 4 of Fig. 3.

In the illustrated embodiment of my invention the shipping ycontainer comprises inner and outer cartons and 11 respectively, each being of rectangular form and the inner carton being securely held in a diagonal position (Figs. 2 and 3) such that the bottle B or similar cylindrical article, throughout its circumference, is spaced inwardly from the exterior wIall of the shipping container a substantial extent. Thus breakage of the bottle or such article, even if the sides of the container are somewhat crushed, is highly improbable.

The inner carton 10 as shown is a tube of rectangular cross section having end closing flaps 10a.

The outer carton 11 is formed from a paperboard blank (Fig. 1) comprising an elongated rectangular sheet 13 having three longitudinally spaced transverse score lines 14 and a pair of longitudinal score lines 15. These score lines 14 and 15 define the side and end margins of side 2,790,588 Patented Apr. 30, 1957 Wall panels 16 which when the carton is set up, las shown in Fig. 2, produce the body of the outer carton 11. The longitudinal score lines 15, together with slots 17 extending transversely outward from said score lines 15, to the longitudinal margins of the blank, dene a pair of opposed closure aps 18 at each end of the outer carton and two plairs of locking llaps 19 at each end of said carton. In the blank (Fig. l) the pairs of locking aps 19 and the closure aps 18 are alternately arranged along each longitudinal margin. Eachy of the locking flaps is composed of a flap proper 20 of generally triangular form and a tab 21 also of generally triangular form, such resulting from the presence of the diagonal score line 22 as shown.

In assembling, or setting up the container, the cartons are telescoped one Within the other as indicated in Figs. 2 and 4, the bottle B or such Iarticle being placed in the inner carton prior to or after partial setting up, as desired. The inner carton is diagonally positioned so that the longitudinal corners are in contact with the wall panels of the outer carton substantially medially of the corners of the latter. Thus the longitudinal axes of the inner and outer cartons coincide.

The locking flaps 20 are then pressed slightly into the triangular spaces at the corners of the outer carton with the depending tabs 21 lying against the Wiall panels of the inner carton. The opposed cover flaps 1S are then glued in closing position and assist in retaining the locking flaps against accidental retraction. Thus, the container is readied for shipment tand the inner carton firmly and reliably held against shifting about its axes relative to the outer carton.

Modifications may be resorted to within the spirit and scope of the appended claim.

l claim:

A shipping container comprising 'nested inner and outer non-circular tubular cartons having a common longitudinal axis, each carton Ihaving interconnected side wall panels providing a series of parallel longitudinal corners, the inner carton having each of its longitudinal corners positioned substantially midway between and parallel to a pair of corners of the outer carton and therewith providing an 'open longitudinal space of triangular cross-sectional contour between and defined by one of the side wall panels of @the inner carton and one longitudinal half of cach of a pair of contiguous panels of the louter carton, a pair of rectangular locking flaps at each end of each lof a pair of opposed side wall panels of the outer carton, each locking ap being formed integral with and as a longitudinal extension of one-half the width of the side Wall panel of the outer carton and scored diagonally to provide a ltriangular portion of substantially the s'ame area and dimensions as the cross-sectional area and dimensions of one of the open longitudinal spaces, to close one end fof the latter and in part secure the inner carton against lateral movement and a lgenerally triangular tab portion on the lap projecting into the longitudinal space and lying snugly against the adjacent side wall panel 'of the inner carton, and closure flaps carried by the other opposed pair of side wall panels of the outer carton and adapted to overlie the locking tlaps and the adjacent end of the inner carton.
