readily removed from the frozen mass by the Consumer.

Another object of this invention is to provide a paper receptacle of the self-extended type adapted to receive ice cream or the like with a tear tab whereby the paper cup may be readily removed from the frozen ice cream mass by the consumer.

In accordance with the general features of this invention, there is provided a paper cup having a straight edge transverse fold-up and a naturally open self-extended body, which body has projecting from it a tear tab by means of which the cup may be pulled off of a frozen mass of ice cream therein.

In accordance with still other features of the invention, there is provided a blank for a cup adapted to receive a frozen confection comprisconverging side edges extending from said outer edge toward the lower end of the cup to be formed from the blank and having disposed adjacent their 1 inner extremities portions adapted to be folded about a transverse line of fold to define abottom closure for the cup; one of the side edges of the cup having projecting from it a stripping tab by means of which the cup may be removed from the frozen confection therein.

Other objects and features of this invention will more fully appear from the following detailed description, taken in connection with the accompanying drawings which illustrate an embodiment and a modified form thereof, and in which Figure 1 is a view of a blank embodying features of this invention.

Figure 2 is a side view of a cup made from the blank shown in Figure 1.

Figure 3 is another side view of the same cup shown in Figure 2.

Figure 4 is still another side view of the same cup.

Figure 5 is a top View of the 'cup.

Figure 6 is a view of a blank somewhat different in form and embodying features of this invention.

Figure 7 is a side view of a cup made from the blank shown in Figure 6.

,Figure 8 is another side view of thesame cup shown in Figure 7.

The reference character I0 designates generally a cup body blank which may be made of paper or any other suitable material. This blank comprises a sector of a circle and. includes a curved outer edge H, and inwardly converging side edges I2 and I3. The sidejedge 12 has associated with it a tear or stripping tab M by means of which the cup fabricated from the blank may be stripped from a frozen confectionin the cup.

The margin of the blank adjacent the side edge l3may have spaced dabs of adhesive l5 disposed thereon, or, if preferred,.in lieu thereof a crystallizing glue may be spread in strip fashion over the area defined by the dabs I5, either method permitting ready separation of the cup seam and the stripping of the cup from the frozen confection. The adhesive should be of such amount and character as to merely holdthe cup in shape, but atthe same time being insufficient to preclude ready separation of the glue'dsurfaces when the blank is stripped from a confection therein by the tear tab Id.

The inner extremities of the side edges I2 and I3 terminate in a transverse fold-up adapted to define a bottom closurelfor the cup. More specifically, this fold-up includes spacedtabs l8 and I9 separated byacentrally disposed opening These tabs are adapted to be folded,- upe wardly upon the body of the blank proper and more specifically about transverse linesof fold indicated by dotted lines 2|, 22 and 23. It will also be noted that betweenthe line of fold 23 and the opening there is a narrowstrip of .to each other so that when the blank is folded intoth shape of a cup these lines will be superimposed whereby the tabs or layers l8, l9 and 25 may thereafter be folded upwardly alongone side of the body of the cup as best shown in Figures 3 and 4.

Attentionis also directed to the fact that the tab I8 is provided with a dab of adhesive 26 by means of which it may be secured to the tab l9 which is disposed .under the tab. 18 when the blank is folded into the shape of the desired cup.

The blank illustrated in Figure 1 may be formed or folded into the cup illustrated in Figures 2 to 5 inclusive by any suitable cup manufacturing machinery. I This cup is so formed that it is creaseless except at its lower or bottom '55 closure. The curved edge ll serves to define a self-extended substantially rounded mouth for the cup. Also the line of fold-up is of sufficient length to throw substantially the entire body portion into an elliptical section. Furthermore, the cup thus formed from the blank tapers downwardly from itsmouth in wedge-like form to the previously described bottom closure which provides a base for resting the: cup against the finger of the user. This construction of the cup is- .desirable for the reason that it enables'ready removal of the cup from a container having a plurality of these cups in nested relationship.

In Figures 6 to 8 inclusive, I have shown the present invention in a slightly different form than that exemplified by Figures 1 to 5 inclusive.

The blank 21 shown in Figure 6 embodies many of the features and details of the blank l0 illustrated by Figure 1, these similarities including the curved outer. edge II, the inwardly converg ing side edges I2 and I3, thetear tab I4 associated with the side edge I2, and the adhesive dabs I5 on the blank marginadjacent the side edge I3. As stated hereinabove, if so desired, a crystallizing glue may be applied in strip manner to the blank margin adjacent the edge 13 in lieu of the spaced dabs of adhesive l5, either method permitting ready separation of the adhesively held surfaces by pulling the tear tab I4 when the blank is in finished cup shape.

As is the case with the blank H1, in the blank 21 the side edges l2 and I3 terminate in a transverse fol'd up to form a bottom for the cup, the

lines of fold being of the same character and indicated by the dotted lines 2|, 22 and 23. It

will be noted that between the opening 28 and the lines of fold, there are in effect three narrow strips of material 29, 30 and 3! opposite the lines of fold 2|, 22 and 23 respectively.

It is apparent, therefore, that the blank 21 affords a saving of material over the blank ID,

in that the tabs l8 and IS on the blank in are fold 2|, 22 and 23 will be superimposed whereby the strips 29, 30 and'3l may be thereafter folded upwardly along one side of the body asbest seen in Figures 7 and '8, providing a substantially straight bottom edge 32 for the cup.

As stated above, the only adhesive necessary for the retaining of the blank in its'cup shape is adhesive that is applied on the margin of the blank adjacent the side edge I3.

The cup shown in Figures '7 and 8 is substantially of the same general shape and contour as the cup shown in Figures 2 to 5 inclusive, having the tapering body terminating in a substaninvention is not to be thus limited but only insofar as defined by the appended claims. The confection such as ice cream mix may be disposed in the such character and amount as to facilitate this stripping operation.

Now I desire it understood that while I have illustrated and described in detail the preferred form of this invention, the invention is not to be thus. limited, but only insofar as defined by the scope and spirit of the appended claims.

I claim as my invention:

1. As an article of manufacture, a container formed from a blank comprising substantially a sector of a circle having a curved outer edge for defining the mouth of the container and side edges converging towards the bottom of said container from said outer edge, said blank being notched substantially centrally adjacent the inner end of the sector to provide a pair of spaced tabs, one being located at the inner end of each of saidconverging side edges, with said notch extending centrally outward between said tabs, said tabs together with a relatively narrow central strip 'therebetween being folded along a transverse line of fold to close the bottom of the container leaving the sides creaseless and the container selfextended,'one of said tabs overlapping only a portion of the other of said tabs.

2. As an article of manufacture, a container formedfrom a blank comprisingsubstantially a sector of a circle having a curved outer edge for defining the mouth of the container and side edges converging towards the bottom of said container, said blank being centrally notched adjacentthe inner end of the sector to provide a substantially symmetrical recess, said, side edges being overlapped and a relatively uniform strip around said notch being folded upwardly along, a transverse line of fold in the finished container, one side edge portion of the fold-up overlapping only a part of the'other side edge portion ofthe fold-up the other and outer side edges of said fold-up being inclined upwardly and inwardly away from converging sides of the container.

3. As an article of manufacture, a paper container having its' body portion in self-extended substantially rounded form, said body from its open mouth tapering in wedge-like form to' a bottom closure made by a straight edge transverse fold-up of the container material, the line of fold of said fold-up being of sufficient length i to provide a base for resting the container against a finger of the user when held in filling position in the hand, said fold-up comprising a pair of outer tabs of container material, one of which overlaps onlya portion of the other which latter portion has a section thereof cut away to reduce the amount of material in the fold-up.

4. As an article of manufacture, a self-extending paper cup including a turned-up bottom closure, said bottom closure being formed by folding up the cup material along a transverse line of fold, and said closure including an external multitab overlap, each tab of which is in overlapping relationship with only a part of the adjacent tab one of said tabs being notched to reduce the 7 amount of material in said turned-up closure.

5. As an article of manufacture, a container formed from a blank comprising substantially a sector of a circlehaving a curved outer edge for defining the mouth of the container, and side edges converging towards the bottom of said container. said blank being centrally notched adjacent the inner end oi thesector to provide a recess disposed inwardly of but directly facing. the center point of said circle, said side edges being overlapped and a marginal strip about said notch being folded upwardly along a transverse line oi the other side'edge portion of the fold up, the

other and outer side edges of said fold up beingi inclined upwardly and inwardly away from con- 5 verging side edges of the container.
