CARTON.

Application filed December a, 1923. Serial No. 678,122.

This invention relates to cartons more particularly those adapted to contain articles of irregular shape.

While not restricted to such use the invention is especially applicable to cartons for packing fiat triangular drinking cups. The packing of such cups involves two problems, first, the provision of a carton whose sides will conform to the general triangular contour of such cups, and, second, the provision of means for allowing for the fact that such cups are thicker at the small end than they are at the large end and consequently will not stack evenly.

One of The objects of the present invention is to provide a carton adapted to pack articles of non-rectangular contour.

Another object of the invention is to provide a carton adapted to pack securely articles of uneven thickness.

Other and further important objects of this invention will be apparent from the disclosures inlthe drawings and specification. The invention '(in a preferred form) s illustrated'in the drawings and hereinafter more fully described.

I On the drawings:

Figure 1 is a perspective viewof a car ton constructed in accordance with the pres-' ent invention.

Figure 2 is a section on the line 22 of Figure 1 with the top of the carton open.

Figure 3 is a perspective view of the upper part of the carton partly opened.

Figure 4 is a plan view of the carton collapsed flat for shipment or storage.

Fi ure 5 is a plan view of the blank from whic the carton is made.

As shown on the drawings:

The carton is formed from a blank 10 composed of three broad strips 11 and three narrow strips 12 alternately arranged with lines of fold therebetween adapted to form the six vertical sides of the carton. While the carton is actually hexagonal since every other side is much narrower than the intervening sides the cross-section is of general triangular form. The hexagonal or flattened corner form has several advan tages over a truly triangular shape. In the the cartons will nest in a smaller space than they would otherwise.

The body of the carton also includes a pasting strip 13 for attachment to opposite edges of the blank.

Two of the strips or side portions 11 are provided at each end with

extensions

14 and 15. Each of these extensions includes a.

main portion of similar configuration to the cross-section of the carton and, therefore, adapted to close the bottom and top of the latter. To the main portion of the

extensions flaps

16 and 17 are connected with intervening lines of fold.

These flaps are adapted to be tucked inside the wall of the carton between the latter and the contents thereof to aid in holding the main portions of the extensions in position.

If desired glue or other adhesive may be employed for cementing together the

flaps

14 and 15, particularly at the bottom of the carton.

It will be observed that the

extensions

14 and 15 and their attached

flaps

16 and 17 are not identical in form. The extensions 15 and attached flaps 16 are out 01f in line with the line of fold 18 so that, after the pasting strip 13 has been secured to the opposite ed e of the blank to form an openended tu the latter may be collapsed about the line of fold 18 to give a fiat article having two straight edges as \,shown in Figure 4.

While one of the lines of fold required in making the carton, such as 18, may be utilized in collapsing the carton, it is also necessary to provide an additional line of told 19 as shown in Figure 5.

As shown in Figure 2 the carton is designed to hold a stack of flat paper cups 20 arranged with their thickened bottoms to the right-hand side of this figure. To provide uniform pressure upon the cups at both top and bottom in spite of the inequality in thickness, fillers-are arranged in the carton preferably, as shown, both at top and bottom. These fillers may conveniently be formed of a single piece of bent pasteboard, the body part 21 being of similar configuration to the cross-section of the carton and extending thereaeross While the flange portion 22 is arranged to engage the top or bottom member of the carton and thereby hold the body portion at an angle to such end of the carton.

My improved carton preferably is formed of commercial pasteboard, but may be made of any comparatively thick paper capable of being bent angularly, as by scoring, and in using the term thickened paper in the claims, I wish to define a paper stiff enough to maintain its shape, but which if bent to too acute an angle is liable to iupture along the line of bend. i

I am aware that many changes may be made, and numerous details of construction 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 hereon, otherwise than necessitated by the prior art.

I claim as my invention 1. A carton of thickened paper, bent angularly to the desired cross sectional configuration, two lines of bend being formed at each angle. thereby providing obtuse angles at these points.

2. A carton of thickened paper, bent angularly to substantially triangular cross sectional configuration, the apices of the triangle being formed with a double bend, thereby forming angles double the obtuseness of the normal angle.

3. A carton, and a filler for one end of the same composed of a bent sheet of material having one portion extending along and in contact with one side of the interior of the carton and another portion extending obliquely across the entire carton.

4. A carton, and a filler for one end of the same composed of a sheet of pasteboard having a body portion of substantially the same configuration as the interior of the car ton and a flange portion along one side adapted to engage the end of the carton and thereby hold the body portion at an angle to such end of the carton.

5. A blank for making cartons comprising a sheet of material including three narrow and three wide strips alternately arranged with lines of fold therebetween, and extensions on the ends of certain of the Wide strips, said extensions each including a portion of similar configuration to the cross section of the carton and a flap adapted to extend inwardly between the side of the carton and its contents.

6. YA carton comprising a tube of hexagonal cross-section, every other side being of smaller width than the intervening sides. and extensions at each end from t o of the wide sides, said extensions including a portion of a configuration similar to the crosssection of the carton and a flap adapted to extend inwardly between the side of the car-- ton and its contents.

7. A carton comprising a tube having a cross-section of general triangular form, and extensions at each end from two of the sides, the third side having a line of fold therein to allow the carton to be collapsed, said extensions including a portion of similar configuration to the cross-section of the carton and a flap adapted to extend inward- 1y between the side of the carton and its contents.

In testimony whereof I have hereunto sub scribed my name.
