10 Claims.

This invention relates to cartons or boxes, and more particularly to such containers as are made from unitary blanks of foldable material.

` One of the objects of the present invention is to provide a novel carton which may be formed from aunitary piece of foldable material, the carton blank being readily formed by a suitable die and its elements being easily foldable into proper relation to form the complete carton.

Another object is to provide a cartonof hexagonal cross-section which may be easily and economically formed from a unitary blank of foldable material.

A still further object of this invention is to provide improved means for fastening the end closure flaps against displacement.

Another object of this invention resides in'the improved construction. of the ends of such a container, which will eectively seal the container against leakage and at the same time permit easy operation of the opening and closing of the same. A further object is to provide a container of the character aforesaid which may be shipped in at knocked-down condition by the manufacturer to the user and set up bythe latter preparatory to placing the goods in it Without the use of special equipment, adhesives or the like. Y

A still further object is to provide an integral carton blank of novel shape which may be quickly and easily folded to form a carton of hexagonal cross-section.

These and other objects will appear morefu'lly from a consideration of the detailed description of the invention which follows. Although only one embodiment of the invention has been de-fr scribed and illustrated in the accompanying drawings, it is to be expressly understood that these drawings are for the purpose of illustration only and are not to be construed as a. limitation of the scope vof the invention, reference being had for this purpose to the appendedclaims.

In the drawingsz v Figure 1 is a plan view of one form of blank from which a carton maygbe constructed in accordance with the present invention,

' Figure 2 is a fragmental View of the blank shown in Figure 1 having one panel folded over and glued, v

Figure 3 is a plan view of the completed carton folded Hat for shipment,

Figure 4 is a fragmental perspective view of the carton with the closure flaps in extended open position,

Figure 5 is a fragmental perspective View of the carton showing the inner closure flap in closed position,

Figure 6 is a fragmental perspective view showing the outer closure flap in partially locked conreference characters indicate like parts throughout the several views, there is disclosed therein a carton or box which isrmade from a unitary blank of novel shape, the various elements of the blank being readily foldable to form the complete carton and suitable means being provided for quickly and easily sealing said elements in assembled relationship. As shown, the carton is preferably formed from a unitary blank of any suitable foldable material such as cardboard, having a substantially rectangular body portion suitably scored transversely along the lines I, 2, 3, 4, 5, 6 and 1 in order to form a plurality of panels I0, I I, I2, I3 and I4 which form the sides of the carton when it is assembled, and panels I 6 and I1, constituting a. securing or pasting ap. Panel I1 of the pasting flap is adapted to be folded back on itself on score line I inthe position shown in Figure 2 having one face thereof glued to panelA I6 by adhesive 40. The outer face of panel Ilqis adapted to be coated with a suitable adhesive and secured to the outer surface of the opposite end panel I0 as shown in Figure 3 to form the completed carton. If desired, the pasting flap may be formed of a single panel instead of being folded back on itself.y In the preferred form shown, the body portion pf the blank includes six rectangular panels of equal size for forming a carton having a hexagonal cross-section, but it will be understood that the invention is not limited to cartons having rectangular sides, or even to sides all of the same size.

In addition to the body portion comprising the panels forming the sides of the carton, the blank is also provided with suitable appendages which are adapted to form the end closures of the carton and which include suitable means for easily and quickly sealing said closures in place. In the form shown, one of the panels intermediate end panels such as panel I3 is scored at its extremi- 55 ties as indicated at 26, beyond which score lines the panel is provided with a pair of end flaps 20.

In the embodiment shown, end iiaps 2D are hexag- Y onal in shape and substantially equal inarea to the cross-section of the assembled carton, and are adapted to form the outer end closures therefor. In order that these end closures may be easily and quickly locked in place, end iaps are provided with slits 30 and 3I which are adapted to receive

locking tongues

22 and 24 provided, respectively, at the ends of panels II and I5 hinged thereto on

score lines

9 and 28, respectively.

Tongues

22 and 24 are provided, respectively, Withscore

lines

33 and 32 to facilitate exing of the tongues for insertion in slits 30 and 3l of the end closures.

In addition to the louter end closure iiaps, just described, suitable means have also been provided for furnishing the carton with inner end closure iiaps in order to insure a thoroughly tight,

leak-proof container especially well adapted for containing ice cream or other comestibles which may be placed in the carton in liquid or semifrozen condition and then hardened therein so as to assume the contour of the carton. In the embodiment shown end panel I0 is scored at its extremities as indicated at 8, beyond which score lines said panel is provided with a pair of inner closure flaps I8. These inner aps are also hexagonal inl shape and of the same size and area as end flaps 20, and equal in area to the crosssection of the assembled carton.

In order to retain the inner' flaps in position when the carton is set up, panels I2 and I4 are provided with score lines 25 and 21' respectively, beyond which are

polygonal iiaps

23 and 38, respectively. The said flaps are also free from end closures 20 owing to slits 38 and 31.

In forming the carton for shipping in at condition to the user, panel I1 is folded back on score line 'I and glued to panel I8 by adhesive 4U, as shown in Figure 2. Panel II is then folded on score line 2, as shown in Figure 3, carrying with it end panel I0. The outer exposed face of the folded-over panel I'I is then glued by adhesive 40 to the marginal portion of end panel I0 as shown in Figure 3. The outer and inner flaps 20 and I8 will then be in superimposed position as shown in Figure 3 and

tongues

22 and 24 will be superimposed upon

tetragonal iiaps

23 and 38, respectively. 'Ihe carton is shipped to the user in this flat condition.

In using the carton for packaging ice cream or other comestibles therein, the body of the carton is folded along score lines I, 2, 3, 4, 5 and 8 to form a hexagonal body portion, as shown in Figure 4, with the end flaps in extended position. An inner iiap IB at one end of the carton is then folded on score line 8 to close the end of the carton, as shown in Figure 5.

Tetragonal flaps

23 and 38 are then folded over the inner flap. 'I'he end closure iiap 20 is then folded over on score line 26 to overlie the inner closure flap, as shown in Figure 6.

Tongues

22 and 24 are then inserted in

slits

30 and 3|, respectively, thereby locking one end of the carton. 'I'he carton is then placed on its closed end and filled at its open end with liquid or semi-liquid ice cream or other comestible. II'he inner and outer closure flaps at the open end of the carton are then locked into position in the same order as previously described and the carton with its contents is then placed in a freezing chamber to harden the contents therein, causing the contents to assume the hexagonal contour of the carton.

The construction of the carton is such as to provide a smooth continuous interior surface throughout. The ends of the carton are also smooth internally as shown in Figure 8. During the lling operation no leakage will occur at the edges A, B, C, D and E at the inner flaps owing to the manner in which the closure fiaps are constructed and retained in position.

When the consumer desires to use the contents in the carton, theexposed edge of panel I6 is seized and pulled back with the fingers, as shown in Figure 9, thereby breaking the adhesive bond of the folded-back panel I'I to the margin of panel I Il. Owing to the bent panel I1, the carton is readily opened Without tearing or peeling the iibres on the inner face of the carton. The carton willy open up in substantially flat condition as shown in Figure 10, and will support the ice cream or other comestible thereon which can be sliced into slices of hexagonal contour for individual servings.

'Ihere is thus provided by the present invention a novel form of box or carton made from a unitary blank of foldable material which is provided with both inner and outer end closures and novel sealing means for providing a tight, leak-proof container especially well adapted for containing frozen comestibles. 'I'he blank from which the carton is formed comprises a single piece of foldable material of novel shape suitably scored for quick and easy folding into the desired form. Both inner and outer end closures are provided, the inner end closures forming 'a smooth interior. When folded to assembled form, every external edge of the carton isprovided with a complete, ,continuous covering so as to effectively prevent leakage. 'I'he carton thus formed is simple in structure, and inexpensive of manufacture both as to material and the labor of assembly.

It will be obvious that the invention is not limited to the specific form described andv illustrated in the accompanying drawings, but is capable of a variety of mechanical embodiments. For example, the panels forming the sides of the carton may be of any desired shape and size instead of rectangular and equal as shown, and the closure 'flaps may be secured to any of the panels in any desired arrangement other than that illustrated. Also, it will be understood that the carton may be constructed in accordance with the present invention with a different number of sides than six, and that the closure flaps may accordingly vary in cross-section from the hexagonal form shown. Various other changes, which will now appear to those skilled in the art, may be made in the form, details of construction and arrangement of the parts without departing from the spirit of the invention, and reference is therefore to be had to the appended claims for a deiinitlon of the limits of the invention.
