9 Claims.

This invention relates to cartons of thevariety commonly made of paper, cardboard or other sheet material, for holding substances such as ice cream or other food products, an object of the invention being the provision of a simple and inexpensive carton of the above character of sumciently tight construction to hold fluid or semifiuid contents, such as ice cream, and yet capable of being quickly and readily torn apart by the consumer for convenient access to the contents.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

. This invention isin the nature of an improvement upon the carton disclosed in the patent to Inman and Bloomer No. 1,908,251, dated May 9, 193.3, and is capable of various embodiments.

elevation of a somewhat modifrom which the carton on the line i'4a--i4a in Fig.

One of the embodiments herein disclosed by way of illustration is an ice cream pail illustrated in Figs. 1 to 6, inclusive, and 10 of the drawings. Referring first to Fig. 10, the blank is cut and scored, as shown, for folding to form a bottom 20 5 and a pair of opposite side walls 2| and 22. These side walls are provided with inwardly folding flaps 23, 24, and 26, the opposite ones of which are overlapped-and gluedtogether to form a second pair of opposite side walls indicated gen- 1.0 erally at 21 and 28 (Fig. 4).

The bottom has upwardly folding flaps 29 and 30, preferably of the substantially triangular shape shown, for cooperation with the flaps 23 and 24 to form the second pair of side walls, .these 15 flaps being cut away as shown so that in the erected carton they lie in the same plane. as shown in Figs. 3, 4, and 5. It will be noted that the edges 3| and 32 of flaps 23 and 24, respectively, are so shaped as to extend (Fig. 3) sub- 20" stantially diagonally endwise or from top to bottom and also across the carton fromside to side. The side walls 2| and22 carry flaps 32 and 34 for folding across the top of the carton. The other side walls carry over flaps 33 and 34 and provided with tongue and slot means 31 and 38. of any known or suitable variety, to be'manually engaged or interlocked to secure the end flaps together to form aclosure for the top or filling opening of the carton.

In the erected carton of Fig. 1, side wall flaps 25 and 26 are preferably supplied with glue, as conventionally indicated in Fig. 10, and folded exteriorly to overlap side flaps 23 and 24 and bottom flaps 29 and V 26 are formed with weakened tear lines 29 and 40, by scoring or other equivalent means, as well understoodin the art, located to extend along and substantially coincide with the edges of the flaps 23, 24, 29 and 30. In Fig. 6, there is shown gen- 40 erally at 4| a known form of such scoring, while Fig. 7 shows similar lines of scoring 42 and 43 from opposite sides of the sheet and slightly spaced apart on opposite sides of the edges of the inner flaps to confine the tearing. Where 4 desired, flaps 25 and 25 may be glued to fiaps 23 and 24 only and not to the bottom flaps 29 and 30.

Figs, 8, 9 and 11 show a pail of similar construction, except that the bottom flaps 44 and 45 are more nearly rectangular in shape and the weakened tear lines 46 and 41 are formed by spaced indentations or perforationsin the sheet material as understood in the art, as distinguished from the substantially continuous cut or indentation shown in the modification of Fig. 1.

flaps 35 and 36 which are folded 25' 30, and these fiaps 25 and 35 In this modification also the glue is discontinued adjacent the tops of the flaps 44 and 45 which are located between the flaps on the side walls but are free to slide out as the side wall flaps are torn to open the carton.

Both of the modifications of Figs. 1 to 11, inclusive, in erected condition, are filled through the top opening and closed by folding in and securing the described flaps 33, 34, 35, and 36. To remove the contents, these fiaps are opened and flaps 35 and 36, with the fiaps 23, 24, and portions of flaps 25 and outwardly and downwardly so as to tear the flaps 25 and 26 along the weakened lines 39 and 40. It has been found that such tearing is greatly facilitated by the reenforcing and strengthening of fiaps 25 and 26 by the flaps 23, 24, 23 and 30. Also that the underlying substantially coincident edges of the flaps 23, 24, 29 and 30 act as sharp straight edges which guide and confine the tearing action against extending into and stripping other portions, with the result that the tearing is quickly, readily and cleanly efiected and confined to the desired line which preferably extends, as shown, from top to bottom and side to side so as to fully expose the contents of the carton for removal. This embodiment thus affords the convenient tapered and nesting type of pail in a simple, tight, and inexpensive consiguction without cumbersome projections, but capable of being quickly and easily torn apart along the desired lines for exposing the contents.

Figs. 12 to 16, inclusive, illustrate the application of the principles of the invention to the socalled linerless or rectangular type of carton. The blank is cut and scored, asshown in Fig. 15, .to form pairs of opposing side walls 48, 49, and 5|. Side wall 5| overlaps externally and is glued to a flap 52 on wall 48, preferably of the shape shown. Each of the side walls 48 to 5| is provided at both ends with inwardly folding end closure flaps, of any known or suitable construction, and the opposite outer pair of these flaps at each end are formed with tongue and slot means, 53 and 54, of any known or suitable type, for securing these flaps in closed position. The inner side wall flap 52 is also preferably provided at one end with a closure flap 55 as shown, which is preferably glued to the under side of an end flap 56 at the other extremity of the blank to reenforce the same and assist in the opening of the carton, as further described hereafter. The glue may be applied to flaps 52 and 55 in various ways, and is here shown applied in spaced lines 51 fallingon opposite sides of the locking slot 54 so as not to interfere with the entrance of the tongue 53.

The provision for tearing down this modification of Figs. 12 to 16 comprises the inclined edge 58 on the inner side wall flap 52 arranged to extend from end to end and side to side of the carton as shown in Fig. 15. In addition the overlying outer side wall 5| is scored and weakened in any known and suitable manner indicated generally at 59 substantially along or coincident with the edge 58 ofthe inner fiap. This scoring of wall 5| is preferably from both surfaces in slightly spaced lines, as indicated at 60 and 6| in Fig. 16, these lines being on opposite sides of the edge 58 of the underlying flap which cooperates with such scoring in wall 5| to produce a highly efficient form of weakening by which the tearing action is facilitated and confined to the desired line, in accordance with thiaprinciples 26 glued to them are pulled described above in connection with theembodiment of Fig. 1.

The carton of Figs. 12 to 16, inclusive, is closed at one end, filled and closed at the opposite end, and when it is desired to remove the contents it 5 is opened at the end which comprises the double flap formed by the gluing together of the end flaps 55 and 56. This end of the carton may be identified by any suitable designation, and this reenforced flap-means is grasped and pulled outwardly, thus affording a strong means for tearing the carton along the weakened line. Such action forces outwardly the edge 58 of the inner fiap 52 to act as a straight edge along the lines of scoring, and this action, under the outward pull on the adjacent reenforced portion of the wall, quckly and easily tears the wall alon the weakened line. This severs the carton from end to end and side to side and effectively opens it up for full access to the contents.

The invention in thus accomplishing its objects, contributes to the convenience and efficiency of the pail and linerless" types of cartons by providing them in a form affording convenient access to their contents in a construction which is economical of materials, free from cumbersome" projections, and readily operated by the user.

While certain embodiments of the invention have been disclosed, it is to be understood that the inventive idea may be carried out in a number of ways. This application is therefore not to be limited to the precise details described, but is intended to cover all variations and modifications thereof falling within the spirit of the invention or the scope of the appended claims.
