Abstract

The carton (10) for pastry, cakes, sweets in general, in bulk or freshly produced which can be obtained immediately, using a one-piece shaped sheet provided with foldings (13, 22) pre-marked including opposite trapezoid side panels (14, 15) provided with slots (47-48) and hooks (35-38) for the spontaneous stabilization of the closing position of the packet (10) itself and a handle (29) for easy carrying.

Description

ONE-PIECE CARTON FOR SWEETS ETC the invention relates to packets of the facilitated assembling type for carrying in general pastry, cakes and sweets bought in bulk or fresh produced.

As already konwn, in confectionery shops it is poss.υle to by fresh produced sweets of different sizes, such as pastry, cakes, tarts or the like. Pastry are put on trays of different sizes and then the whole thing is wrapped in sheets of dif¬ ferently decorated paper.

The small parcel obtained is then tied up using a string, a ribon or the like for better steadiness and to facilitate the grip with the fingers. Obviously this process takes time and also trained staff since the packaging has to be done rapidly, elegantly and firmly at the same time. Particularly in rush hours or periods all these needs can create many difficulties also keeping in mind the substantially seasonal type of particular sweets. The subject-matter of the invention will eliminate the above mentioned pro- blems as per the following description.

The subject-matter of the invention is a packet for pastry, cakes, sweets in ge^¬ neral, in bulk or fresh produced, obtained by a one-piece shaped sheet, with pre-marked folding, including spontaneous means for stabilization of the closing position of the packet itself and a handle for easy carrying. The one-piece sheet has a bottom area, poligonal in shape, the sides of which are connected by foldings, to regular trapezoid side panels of the same height with outer shorter base.

A first pair of two opposite side panels are connected by a folding, with an ex¬ pansion in shape and surface which is slightly less than half of the surface of the bottom area. Said expansion is itself connected by a folding, to a strip having bent upper side provided at the two ends of two recesses which form two hooks one turned to¬ wards the other.

A second pair of opposite side panels orthogonal to the side panels of the first pair, are connected by a folding to a strip having an axial slot. The axial positions of said slots are such that their outer ends are at a distance from the foldings between the strips and the trapezoid side panels, almost equal to the distance between the bottoms of the recesses predisposed on the bent strips of the first pair of opposite side panels and the ends of the folding between said strips and the expansions which support them. Thus it is possible to close the packet carrying out on the first pair of opposite side panels two consecutive foldings at 90° upwards and then a folding at 90° outwards.

By said last two foldings it is determined the mating of the bent strips in axial position with respect to the packet. Having done this it is determined the passage through the slots of the strips of the second of side panels, of the hooks of the strips of the first pair of opposite side panels. Not acting on said side panels it is obtained as consequence of their tendency to spontaneously turn away beacuse of the elastic reaction, the meshing of the slots inside the hooks and therefore the sponaneous stabilization of the closing of the packet. The bottom area is preferably rectangular in shape whereas the trapezoid side panels are formed by two orthogonal pairs.

The side panels with the expansions on which are the bent strips provided with hooks, start from the shorter sides.

One of the pairs of opposite trapezoid side panels i provided with side tongues. Said side tongues are preferably located on the longer trapezoid side panels.

In the middle of each of the bent strips there are two holes one near the other the sizes of which are such to permit the fingers of the hand passing through them so that it is easy to carry the packet.

Preferably the sheet used for the packet is made of board. The foldings are pre-marked by knurling or similar process by which a hollow is created on the surface of the sheet suitable to facilitate the folding simply using the hands.

The advantages of the invention are manifest.

Using a simple punched board it is possible to obtain istantly a packet for sweets which is at the same time useful, elegant and takes up little room.

The forming of the packet and its closing are very rapid.

The storage of the packets thanks to their flat devepolment, clearly takes up lit¬ tle space.

The hanlde obtained by the pair of axial holes, makes the design more elegante and original and makes possible to suspend easly the packet to the fingers and its easy carrying.

The cost of the packet is very low in respect to the present systems. In short, the invention provides functionality, elegance and a lower cost as well as maximum hygiene and protection for the product.

The features and purposes of the invention will be even more apparent from the following exemple of construction supplied with schematic drawings. Fig. 1) The packet subject-matter of the invention flat developed

The box-shaped packet 10 is obtained from a board sheet 11 including a rec- tangular area 12 connected, by foldings 13 almost at 90°, to four trapezoid side panels 14, 15, 16, 17 substantially of the same shape.

The longitudinal side panels 14 and 16, are laterally connected by foldings 20, to the tongues 21 substantially rectangular in shape.

The fourth side of said side panels 14 and 16 is connected, by the foldings 22 to the rectangular expansions 25 and 26, substantially the same.

Said expantions have an area a little less than the longitudinal half of the rec¬ tangular bottom area 12, their bent shorter sides 55 are themselves connected by the foldings 27 to the strips 28 and 29 which are the same with bent edges

30. At the ends of said edges are located the pairs of hooks 35-36 and 37-38 inwards orientated.

In the middle of the strips 28 e 29 are located the pairs of large holes 40-41 and 42-43.

The traverse side panels 15 and 17 are longitudinally connected by foldings 45, to the triangular strips 46 which are provided with the axial slots 47 and 48.

The sides 49 of the triangle are bent inwards. As it is clear looking at Figs. 2) and 3), by the foldings the board can be tran¬ sformed in an elegant and useful box.

In fact, inside this box it is possible to put a tray 51 for sweets 52 as showed in

Fig. 2). Fitting toghether the bent strips 28 and 29 and then passing the pairs of hooks

35-37 and 36-38 respectively through the slots 47 and 48 and not acting on the packet its stabilisation in the closed position is caused.

In fact, the traverse side panels 15 and 17 bacause of their elasticity get open and move outwards (see the arrow) in the opposite direction with respect to the direction of the hooks 35-37 e 36-38 (see arrow) in this way strengthening and stibilizing the mesh of said hooks against the upper edges 50 of the above mentioned slots.

The pairs of holes (40-41) and (42-43) permit an easy grip using two fingers 53 of the hand.
