tCiairns. (Cl. 40126) The present invention relates generally to cake dummies and to foldable blanks therefor, and in particular to blanks which are foldable into the form of a cylinder with an open base and a closed base, to be used as a cake dummy. Y

It is a practice in bakeries to display frosted cakes in. a window or case, such display being usually dummies in the form of cakes covered with frosting. Also, in catering schools, such dummies are used for cakes in training for the artistry of frosting.

It is the object of the present invention to provide a single piece of foldable flat material as a blank which is readily converted into the form of a cake to be used as a cake dummy.

It is a particular object of the invention to provide a cake dummy in flat blank form which can be folded and united without use of any instrument or additional means or material.

Another object of the invention is to provide a cake dummy with a cylindrical wall and a flat top and with internal vertical supports for the flat top.

Various other and ancillary objects and advantages of the invention will become apparentfrom the following description and explanation of the invention as illustrated in the accompanying drawings in which:

Fig. 1 is a representation of the blank as it is cut and ready for folding.

Fig. 2 is a front view of the cake dummy showing the position of one portion of a wall-former as it is about to be joined with a portion of another wall-former.

Fig. 3 is a view similar to Fig. 2 showing the two wallforming portions joined together.

Fig. 4 is a partial view of the completed dummy taken from the underside, as looking upwardly in Fig. 3.

Fig. 5 is a perspective view of the completed dummy.

In general, the blank includes a substantially circular section or cylinder base on the periphery of which there are narrow hinging score linesintegrally connecting the base with a plurality of tangential strips which are to con-,

of adjacent strips overlap. The overlapping portions ahe.

provided with interlocking means so that they may form a continuous cylindrical wall. The strips may be two or more in number. The more strips there are, the more regions there are of integral connections between cylindrical wall and base. Also, the more strips there are, the shorter the strips may be with appropriate decrease in a dimension of the blank.

It has been found that four wall-forming strips of identical shape and size permit the blank to be made in the general form of a square'with a minimum loss or waste of material. Fig. 1 shows such a form having a base or circular section of which the major extent of the periphery is a cut edge designated 11. The periphery at 90 regions is formed by short straight folding scores illustrated by dotted hinging lines 12 which serve as integral connections of the base it) to the four wall-forming strips designated 13.

Each strip 13 is tangential to the base 10 and all have the same width which becomes the height of the cake dummy. By the .choice of proportions shows, a wingend 14 of each strip 13 is separated from a tongue-end States Patent 0 2,858,630 Patented Nov. 4, 1958 15 ofan adjacent strip 13 by a cut 16. The said wingend 14 is arranged; to. reside inside the cylindrical wall and is foldable to extend inwardly from the wall as a vertical support by the provision of scored. folding line 18 running perpendicular to the extentof the strip.

The tongue-end 15 coacts with a tongue-receiving slot 20 therefor, both tongue and slotformed and positioned to unite adjacent strips with a minimum departure from a trulycylindrical connection. As shown, the interlocking means includes in addition to tongue and slot, mutual interlocking slots. Commonly, such interlocking means results in strain and stress. By locating the regions of the tongue and slot connection in the vicinity of the hinge 12, as by positioningtheslot 20 in line with the hinge 12, the tendency of each tongue-end 1510 move each receiving strip outwardly, is resisted by the tie at the hinge.

The horizontal slot 20 has at one end a vertical extension 20'. Tongue 23 (Fig. 2) slips into the horizontal portion 20 and the peak 22 of the notch adjacent tongue 23 moves to the terminal end of the slot extension 20', as shown in Fig. 3. These parts fit together as indicated in Figs. 2' and 3. That portion of the tongue-end. 15 which would lie directly outside the hinge line 12 is cut off as shown by the line 24.

Fig. 4 shows the completed cake dummy inverted to indicate the position of the'wing-ends 14 of the strips 13 as they are turned inwardly to give vertical support to the base 10, for example, to resist the'weight of frosting applied to the top.

In "the preferred form illustrated, having four integral connections between the completed wall and the base 10 the wall. However, additional connecting means may be provided and are illustrated in Fig. 1, although it is to be understood that they are optional in such form. The four strips designated 26 which extend normally from the periphery 11 ofthe base at locations between each pair of hinges 12, provide tongues which may be entered into slots 27 in each of the strips, thereby to provide additional connections where the top edges of the wall meet with the periphery of the base. These optional tongues and slots mayvary in number and location, any increase in number adding, however, to the operations required in assembling the blank to dummy form.

In' addition to-the connections of tongue and slot between adjacent strips 13, it is to be understood that other means of union may be employed, for example, staples. Where-such means is to be employed, the provision of tongue and slot may be omitted. Likewise, the projecting tabs 26, which are optional-in the illustrated form, may be'stapled to the wall, without the provision of receiving slots therefor. The lines of folding of the material at the periphery of the base, being straight and relatively short, need not bescored for folding, because the structure is such that the action to fold results in a properly located folding line. However, tongues and slots, and scored folding lines are preferred in order to dispense with other instrumentalities for forming the dummy.

From the foregoing, it is to be understood that the invention is not limited to the form illustrated and described. Numerous departures and modifications are contemplated as falling within .thescope of the appended claims.
