This invention relates to improvements in bonbon crackers or cosaques and to the method of manufacturing the same and the object of the invention is to produce a cracker of pleasing appearance and with a minimum of hand labor.

In producing a bonbon cracker or cosaque in accordance with the present invention a mat is formed of a number of superimposed sheets of paper or other thin flexible material, the sheets being stuck together along spaced and usually parallel lines with the lines on one side of each sheet between the lines on the other side of said sheet. From this mat a blank is cut of a length corresponding to the length of the cracker to be formed, the longitudinal cuts being made across the lines of adhesion between the sheets forming the mat. The blank is formed with recesses cut in the longitudinal sides thereof and the cracker is finally formed by drawing the free edges at 20 one side of the blank around the other side and securing the surfaces of the blank together to form a cylindrical body with one or more substantially closed pockets within the interior within which the usual caps, toys or other articles may be inserted during the forming operation, and encircling recesses on the exterior corresponding to the ties of a cracker of usual form.

Preferably the mat is reinforced by sticking sheets of card, thicker paper or other relatively stiff material to the surfaces thereof before cutting.

The invention is illustrated by way of example in the accompanying drawing in which Figs. 1, 2 and 3 illustrate the method of forming the mat.

Fig. 4 shows the form of the blanks cut from the mat.

Figs. 5 and 6 show a partly folded blank.

Fig. '7 illustrates a finished cracker and Fig. 8 shows a detail.

Referring to the drawing, sheets i of thin paper are gummed, glued or pasted along parallel lines 2 as by passing them over suitable adhesive applying rollers in well known manner, and the sheets superimposed upon one another with the lines 2 of adhesive (shown in full lines in Fig. l) on one sheet lying between the lines 2 of adhesive (shown in dotted lines in Fig. 1) on the adjacent sheet. The process is continued until a mat of required thickness is produced as shown in Fig. 2.

In the embodiment shown sheets 3 and 4 of card or thick paper or other relatively stiff material, are pasted, glued or gummed on the upper and lower surfaces of the mat.

The resulting mat is such that the sheets i of paper can be moved relatively to one another upon parting the re-inforcing sheets 3 and 4 to take up the honeycomb formation shown in Fig. 3.-

The mat is cut by means of suitably formed stamping dies to produce elongated blanks 5 of the shape shown in Fig. 4, the blanks being cut transversely of the lines of adhesion 2.

At the centre on one side of the blank 5 is formed a large recess 6 and on the other side are formed two V shaped pinch forming recesses l suitably spaced from one another.

By parting the edges of the blank on the side containing recesses l and folding about the edge containing recess 5, as shown in Fig. 5, and finally bringing the parts of the backing sheets 3 and i into surface contact, the longitudinal cracker body shown in Fig. '7 may be formed and it will be clearly seen that the recess 6 in the blank forms a substantially closed pocket within the cracker and the recesses 1 form encircling recesses around the cracker corresponding to the ties or pinches of a cracker of usual form.

The usual caps, toys or other articles are in serted in the pocket formed by recess 6 as the blank is folded, and if desired the pocket may be lined with paper or other material, for example so that the nature of the contained articles cannot be observed from the exterior of the formed cracker.

A snap or detonator of the usual type (not shown) may be inserted lengthwise in the cracker during the folding operation. The backing sheets 3 and i are secured together in any convenient manner as for example by gumming, gluing or pasting.

To prevent opening or stretching of the ends of the cracker and to ensure the folding of the mat to a true cylindrica1 form, hinge strips 8 of thin paper, fabric or other flexible sheet'material, may be stuck to the edges of the paper at the side of the blank containing recess 6 (Fig. 6). Alternatively, holes 9 (Fig. 4) may be formed in the blank in positions near the ends thereof and adjacent that edge which finally lies within the cosaque into which metal rings I0 (Fig. 8) may be inserted as shown in Fig. 5.

If desired the paper strips 8 and the holes 9 and rings IE! may be used together.

Instead of folding a blank to form the completed cylindrical body of the cracker it is to be understood that twoor even more blanks may be used to form together a single cracker. For example two blanks may each be folded to semicylindrical formation and the two backing sheet parts on one stuck to the two backing sheet parts on the other.

The edge of the blank containing recesses I and also the ends thereof may of course be varied in contour to produce crackers of different external shapes and-any convenient external decoration or finish may be applied to the cracker.

I claim:

1. A method of forming a bonbon cracker or cosaque consisting in joining together a number of superimposed sheets of thin flexible material with an adhesive along spaced lines with the lines on one side of each interior sheet between the lines on the other side of said sheet to form a mat, cutting a blank from said mat of a length corresponding to the cosaque to be formed the longitudinal edges of the blank lying transversely of the lines of adhesion and having two spaced pinch forming recesses cut in one longitudinal edge thereof and a further pocket forming recess cut in the other longitudinal edge thereof and located between the two pinch forming recesses, applying hinging means to the blank in the region of the edge containing the pocket forming recess, and drawing the free edges at the longitudinal side of the blank containing the pinch forming recesses around the side containing the pocket forming recess so that both the inner and outer free edges generate substantially true cylinders, and securing the surfaces of the blank together to form an elongated cylindrical body with two spaced pinch recesses encircling the exterior and a substantially closed pocket within the interior.

2. A method of forming bonbon crackers or cosaques as claimed in claim 1, wherein a sheet of material relatively stifier than the thin flexible superimposed sheets is stuck to the upper and lower surfaces of the pile of thin flexible sheets before cutting the blank, the parts of said relatively stiffer sheet material after blanking and folding, being connected together face to face.

3. A method of forming bonbon crackers or cosaques as claimed in claim 1, wherein the blanks are apertured and rings inserted in the apertures to hold the ends of the cosaque against opening.

4. A method of forming bonbon crackers or cosaques as claimed in claim 1, wherein before folding, strips of flexible sheet material are stuck over the edges of the blank which lie within the finished cracker when folded.
