CARTON AND METHOD OF PACKING THE SAME.

Application filed December 3, 1923.

To all whom it may concern:

Be it known that I, CEsARE BARBLERI, a

' subject of the King of Italy, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Carton and Method of Packing the Same; and I do hereby declare that the following is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, and to the numerals of reference marked thereon, which form apart of this specification.

This invention relates to cartons and methods of packing the same adapted more particularly to the packing of articles or other cartons of non-rectangular form in such a way that the latter cannot shake loose or become displaced in their containing carton during transportation.

While not restricted to such use, the invention is especially applicable to cartons adapted to hold smaller cartons of general triangular cross-section such as are employed for packing fiat triangular drinking cu s.

Ilne of. the principal objects of the invention is the provision of a carton and method of packing the same adapted "for articles or other cartons of non-rectangular form.

Another object is the provision of a carton adapted to receive and hold securely smaller cartons of general triangular crosssection.

Other and further important objects of this inventionwill be apparent from the disclosures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter I more fully described.

On the drawings:

Figure 1 is a perspective View of a carton embodying the present improvements.

Figure 2 is a plan view of the same after opemng.

Figure 3 is Fi re 1.

igure 4 is a perspective view of the upper end of one of the triangular cartons partially opened.

Figure 5 is a vertical section through one of the triangular cartons.

.As shown on the drawings:

The carton 1 is of common construction having sides 2, ends 3, flaps 4 from the top a section on the line 2-2 of Serial No. 678,119.

each end of the carton 1. If these are not filled the cartons 6 would be apt to shake loose or become displaced. Consequently, triangular fillers are provided, such as 7,

which may conveniently be formed by folding a sheet of paste or corrugated board into the desired shape.

It will be observed that the corners of the cartons 6 are'fiattened and as a result they can be packed in smaller compass than they could be otherwise.

Further the spaces left at the corners of the cartons 6 when they are packed in the large carton 1 aid in the withdrawal of the cartons 6 as the fingers may be inserted in such spaces.

This hexagonal or flattened corner form has several additional advantages over a truly triangular shape. In the first place the angle through which the pasteboard must be folded or bent is halved thereby giving .a stronger construction for the reason that the greater the angle of fold, the deeper the material must be scored to enable it to bend the required amount. Thus, while the wide sides of the carton 6'. make an angle of 60 with each other, the angles between the wide and narrow sides are 120. Then where. the articles to be packed, although of general triangular form,'do not require a carton of exact triangular shape, considerable carton material is saved by flattening the corners.

A further advantage obtained by forming the sides of the cartons 6- of equal size is that the same may be inserted into the outer carton 1 without regard to the lateral disposition of said sides, as said cartons 6 will interfit under any condition.

The ends of the cartons 6 are closed by overlapping flaps 8 and 9 as shown more particularly in Figure 4.

The cartons 6 are designed more particularly for holdin flat triangular paper cups havin a folde bottom of greater thickness 51311 the top. Such cups will, therefore, not stack evenly within the cartons 6. To provide uniform pressure upon the cups in spite of the inequality in thickness, fillers are arranged in the carton, preferably, as shown in Figure 5, both at top and bottom. These fillers may conveniently be formed of a single piece of bent paste board, the body part 11 being of similar configuration to the cross-section of the carton and extending thereacross while the flange portion 12 is arranged to engage the top or bottom flap of the carton and thereby hold the body portion at an angle to such end of the carton.

I am aware that numerous details of con? struction may be varied through a Wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In combination, a rectangular exterior carton, and a plurality of interior cartons, each of the latter being of hexagonal crosssection with alternate sides of smaller width than the intervening sides, said larger and smaller sides being respectively 01 equal dimensions, whereby said cartons will interfit in the exterior carton under any manner of lateral disposition therein.

2. In combination, a rectangular exterior carton, and a plurality of interior cartons, each of the latter having a. cross-section of general triangular form with the apices of the triangle out 01f, said triangle being equilateral and its cut'otl' apiees being of equal width, whereby said cartons will interfit in the exterior carton under any manner of lateral disposition therein.

In testimony whereof I have hereunto subscribed my name.

CESARE BARBIERI.
