DETAILED DESCRIPTION OF THE INVENTION

[0035] A self folding box (A) for packing one slice of pizza quarter consists of a lower part (1) and a cover (2) (FIG. 1). The lower part (1) and the cover (2) are formed in a tool (FIG. 13) from previously prepared and formed unfolded blank (B) (FIG. 4) and unfolded blank (C) (FIG. 5) made of cardboard. Prepared cardboard is placed in a die (not shown). In the die are positioned knives both for cutting out contours of the sides and stamping out and making slots 1.7, 1.10 and semicircular vent openings 1.11, and inner knives that enter cardboard only partially making previously planned folding lines 1.21, 1.41, 1.51, 1.71 and 1.81 in cardboard of the unfolded blank B, which is intended for the lower part 1 of the box A. The unfolded blank C for the cover 2 of the box is differing from the unfolded blank B only by dimensions of the bottom 2.1 and the lateral sides 2.2 that are bigger in order to enable superposition of the cover 2 on the lower part 1 of the box. Another difference is that the semicircular openings 1.11 are cut out in the inner sides of the lateral sides 2.2, so when the cover 2 is placed on the lower part 1 of the box, then the semicircular openings 1.11 coincide one with another, thereby providing an opening for ventilation of pizza in order to prevent action of vapour.

[0036] The lower part 1 of the box and the cover 2 of the box are formed in the tool 9 (FIG. 13). The formed unfolded blank B, C is placed above the tool 9 on the sides 9.3, 9.4, 9.5, 9.6 and a part of the formed unfolded blank B, C is being pressed on its bottom 1.1, 2.1 by hand until the bottom 1.1, 2.1 becomes pressed against the bottom 9.2 of the tool 9 among the sides 9.3, 9.4, 9.5, 9.6 of the tool 9. Thereby the sides 1.2, 2.2, 1.8, 2.8 of the formed unfolded blank B, C lean on the sides 9.3, 9.4, 9.5, 9.6 of the tool 9 and they become vertical in relation to the bottom 1.1, 2.1. In this position the folds 1.9 fold around the folding lines 1.91, so that the tongues 1.3 enter the slots 1.10 of the lateral sides 1.1, 2.2 and lock the auxiliary sides 1.8, 2.8 and the sides 1.2, 2.2, 1.8, 2.8 in a vertical position. Then the extensions 1.4, 2.4 fold inwards around the folding line 1.41, 2.41 and the opposite side 1.5, 2.5, which folds around the folding lines 1.51, 2.51, 1.71, encloses the extension 1.4, 2.4 in such way to become locked in the slot 1.7 in the bottom 1.1, 2.1 by means of the tongue 1.6.

[0037] In the bottom 1.1 of the lower part 1 of the box A is placed a carrier 4 for two slices of pizza quarter (FIG. 2). The carrier 4 consists of two pads 3, which are superposed one on another so that the tongues 3.3, 3.4 and a next-to-arc tongue 3.6 of the sides 3.2 of the upper pad 3 enclose from outside the sides 3.2 of the lower pad 3, while the trapezoidal tongues 3.5 of the lower pad 3 enter the openings 3.7 of the upper pad 3 for pizza and mutually secure the connection of the both pads 3, whilst an auxiliary tongue 3.9 of the lower auxiliary carrier 3.8 encloses from the outside the upper auxiliary carrier 3.8.

[0038] The pad 3 (FIG. 3) for one slice of pizza quarter is formed by manual folding the formed unfolded blank F along the folding lines 3.21, 3.81, 3.91 (FIG. 6). The unfolded blank F is made of previously prepared cardboard with one applied layer or without it, which is placed in the die with the knives (not shown). The knives cut out the outer contour of the unfolded blank F together with a groove 3.10, an auxiliary carrier 3.8 on the next-to-arc part of the bottom 3.1 and a pivotable extension 3.11. The other knives cut out both the contoures of the tongues 3.3, 3.4, 3.6, 3.9 and the inner sides of the extensions 3.11, wherein star-shaped slots 3.12 have been cut out. The knives, which partially enter cardboard, form previously planned folding lines 3.21, 3.81, 3.91.

[0039] By folding the both sides 3.2 along the folding lines 3.21 upwards in a vertical position in relation to the bottom of the pad 3.1 the pads 3.3, 3.4 and the next-to-arc tongue 3.6 are moved downwards leaving the openings in the bottom 3.1 intended both for facilitating air flow and decreasing action of vapour on pizza. The auxiliary carrier 3.8 is folded downwards in a vertical position, while the pivotable extensions 3.11 of the auxiliary carrier fold inwards over the folding lines 3.81 in such way that sharp edges of the extensions 3.11 enter the star-shaped slots 3.12 in the bottom 3.1 of the carrier 3 for one slice of pizza quarter thereby securing vertical position of the auxiliary carrier 3.8 and the auxiliary tongue 3.9 that is placed onto it. The auxiliary tongue 3.9 prevents a slice of pizza quarter from falling from arcuate part of the pad 3. In another carrier 4, which is formed by superposition of two pads 3 one on another as previously described, can be placed one slice of pizza half, i.e. two slices of pizza quarter.

[0040] The pad 3 for one slice of pizza quarter has the bottom 3.1, which is formed with preferred angle =90.

[0041] Variant I of the self folding box A1 for packing pizza relates to a packing for one slice of pizza sixth. The box consists of the lower part 5 and the cover 6 (FIG. 7). In the lower part 5 of the box on its bottom 5.1, which has triangular shape, is placed the carrier 8 for one slice of pizza sixth. The carrier 8 consists of three pads 7 that are superposed one on another, same as the carrier 3 for one slice of pizza quarter. The pad 7 for one slice of pizza sixth differs from the pad 3 for one slice of pizza quarter in that the bottom 7.1 is formed with preferred angle 1=60 and does not have an auxiliary carrier 3.8.

[0042] The lower part 5 of the box A1 and the cover 6 are formed in a tool that is same as the tool shown in FIG. 13 differing from it only in that it has a triangular bottom (not shown). The formed unfolded blank D, E is placed above the tool and the bottom of the formed unfolded blank D, E is being pressed on its bottom 5.1, 6.1 by hand until the bottom 5.1, 6.1 becomes pressed against the bottom of the tool for forming among the sides of the tool. Thereby the sides 5.2, 6.2 of the formed unfolded blank D, E lean on the sides of the tool and become vertical in relation to the bottom 5.1, 6.1. In this position the fold 1.9 folds around the folding line 1.91, so that the tongue 1.3 enters the slot 1.10 of the lateral side 5.2, 6.2 and locks the sides 5.2, 6.2 in a vertical position in relation to the bottom 5.1, 6.1. Then the extensions 5.4, 6.4 of the sides 5.2, 6.2 fold inwards around the folding lines 5.41, while the opposite side 5.3, 6.3, which folds around the folding lines 5.31, 5.71, 6.31, 6.71, encloses the extensions 5.4, 6.4 in such way to become locked in the slots 1.7 in the bottom 5.1, 6.1. by means of the tongues 1.6.

[0043] In the lower part 5 of the box on the bottom 5.1 is placed the carrier 8 for three slices of pizza sixth (FIG. 8). The carrier 8 consists of three pads 7 that are superposed one on another so that the tongues 3.3, 3.4, 3.6 of the sides 3.2 of the upper pad 7 enclose from outside the sides 3.2 of the lower pad 7, whilst the trapezoidal tongues 3.5 of the lower pad 7 enter the openings 3.7 of the upper pad 7 for one slice of pizza sixth and mutually secure connection of all three pads 7.

[0044] The pad 7 (FIG. 8) is formed by manual folding the formed unfolded blank G along the folding lines 3.21 (FIG. 12). By means of folding of the both sides 3.2 along the folding lines 3.21 upwards in a vertical position in relation to the bottom 7.1 of the pad 7, the tongues 3.3, 3.4 and the next-to-arc tongue 3.6 move downwards leaving the openings in the bottom 7.1 intended both for facilitating air flow and decreasing action of vapour on pizza. The pad 7 can also serve for smaller slices of pizza such as e.g. pizza eight, wherein it is only changed an angle 1 of the bottom 7.1 and the rest stay unchanged. The pad 7 for one slice of pizza quarter has got the bottom 7.1, which is formed with preferred angle 1, most preferably 1=60.

[0045] Forming the box A is done in a tool 9 for forming (FIG. 13), that is same as previously described.

[0046] The tool consists of a tool holder 9.1, on which is attached a tool bottom 9.2. On the tool bottom 9.2 are made sides 9.3, 9.4, 9.5, 9.6, which are inclined in the upper part in order to enable easier sliding of the sides of the unfolded blank B, C, which is placed above it, next to them.
