The invention relates to an individual package containing a pasty food product and equipped with an organ of start-up, as well as a manufacturing process of said container.

Currently, there are different types of packaging individual containing a pasty food product, by example based on melted cheese or cocoa. I understand by product to cocoa paste base a product made from seeds of cocoa that is harvested, fermented to remove the pulp that surround, dry, roast and grind before transforming them into fluid paste by crushing.

Said containers, also called individual rations, generally have, once filled with pasty foodstuff, a square, rectangular or triangular volume, and are provided with a start-up member with a projecting tongue called "zip" to open the container and access to the product it contains. Such portions are especially described in documents FR-A-2 597 436 and FR-A-2 808 782. GB-A-929141 further describes a manufacturing process, by means of a mold, of a shape portion
square.

However, from a technical point of view, the realization of the final form from a thin flat sheet, by example of heat-sealable aluminum, and the starter, with the subsequent filling of said form by the product before of the definitive sealing of the walls, requires multiple operations complex and, therefore, expensive in time and machinery. Further, from an aesthetic, commercial and practical point of view, the way of the packaging of these packages is less and less attractive for the consumer, always looking for novelty.

An object of the invention is to solve these problems proposing an easy procedure to put in practical, which allows to obtain a container that is at the same time easy to use and visually appealing to the consumer.

More specifically, the invention aims at an individual package for pasty food product, for example based on melted cheese or cocoa, characterized in that it has a pyramidal shape and is provided with at least one organ of tearing arranged along at least two sides of a triangle that forms a side face of the pyramid to allow access the product by breaking substantially of said face.

Figure 1 shows a perspective view of an individual container 1 of pyramidal shape, provided with an organ of start 45, which encloses, at the end of a procedure of manufacture object of the present invention, a product pasty food based on melted cheese.

Melted cheese means the product obtained by hot melting, in the presence or not of melting salts, of cheese curds,
cheese (s) only or mixed with other dairy raw materials such as butter, milk powder or whey, fat, anhydrous, protein concentrates, etc. The term melted cheese also includes those products in which the raw materials of cheese or milk are replaced in whole or in part by plant materials, such as fat or protein.

At first, part of the container 100, as is shown in figure 5, it is done by means of a flat sheet 10, for example made of heat-sealable aluminum.

According to a first embodiment illustrated in Figure 2, the initial flat sheet 10 includes four triangles identical equilaterals, with references 15, 16, 17 and 18, which present, two by two, a common side to form jointly a motif that is wrapped around itself same.

Thus, the end triangle 15 it has a base 15a, a first side 15b and a second side 15c; he contiguous triangle 16 has a base 16a, a first side 16b that it is confused with side 15c, and a second side 16c; triangle 17 next it presents a base 17a, a first side 17b that is confused with side 16c, and a second side 17c; and the first triangle of end 18 has a base 18a, a first side 18b that is confuses with side 17c, and a second side 18c.

The four triangles are joined at their vertex common at a crossing point OR opposite to bases 15th, 16th, 17th and 18. They are also provided around said triangles bands that form flaps 19.

Two starter bodies 25 and 35 are provided in two triangles of sheet 10, for example the opposite triangles 15 and 17. Said starter bodies 15 and 35 are presented in the form of starter segments 26 and 36 in petal shape whose tip coincides substantially with vertex O and that evade towards the base of the corresponding triangle. Every starter segment 26 and 36 is extended by means of a tongue starter 28 and 38 protruding from the side of the triangle considered facing the vertex O, that is to say that it stands out respectively of bases 15a and 17a. In this way, the organs of plucking 25 and 35 cover almost all of the triangles in those who are welded and sensitively adopt the shape of a shovel of cake.

According to a second embodiment illustrated in figure 3, sheet 10 is provided with a single organ of Y-shaped start 45 that comes in the form of two starter bands 46a and 46b welded for example along of the sides 17b and 17c of triangle 17, and that join at the vertex Or to be extended by a starter tongue 48 which protrudes from said triangle 17.

According to a third embodiment illustrated in Figure 4, the initial flat sheet 10 includes three triangles identical equilateral references 15, 16 and 17 arranged at Tresbolillo, and they present a common side two by two. An organ of start-up 55 in the form of Y is provided in said sheet e includes two starter bands 46a and 46b welded for example along the sides 16b and 16c of triangle 16. The bands of start 46a and 46b join towards vertex O and extend by a single starter tongue 58 protruding from said vertex O.

According to the other four embodiments of the invention derived from figure 2 and illustrated in the figures 14 to 18, the two starter bodies 25 and 35 are joined between yes near vertex O, for a sequential start of several faces in a single stage.

In figure 14, the first organ of starting 25 is identical to that of figure 2, while the second starter member 35 is devoid of tongue plucking Thus, the sequential start-up of the two faces 15 and 17 are done by pulling only on tongue 28 of the starter segment 26 in the form of a petal.

In Fig. 15, the starter tongue 28 of the first starter segment 26 is offset to one of the sides of the triangle 15, for example the side 15b, while the second starter segment 36 does not occupy the whole of the triangle 17 and is devoid of of the tongue of
plucking

In Figure 16, the first organ of starting 25 is identical to that of figure 2, that is to say in the form of  Petal with a central tongue and tear 28, and the second starter organ 35 occupies only a part of triangle 17 and It is devoid of starter tongue.

In Figure 17, the two organs of starting 25 and 35 are identical to those in figure 2, with the difference that they are linked together at the vertex level O of the triangles Through this configuration, it will be possible to open the container by pulling one or the other of the tabs 28 and 38.

As you can see, in each of the solutions illustrated in figures 2 to 4 and 14 to 17, at least a starter organ extends along at least two sides of the same triangle of the base sheet 10, that is to say along at least two sides of a face of the pyramidal container, for example adopting the shape of a petal or a "Y".

The pyramid-shaped container part 100 represented in figure 5 is made by folding sheet 10 of Figure 2 on itself, so as to approximate the triangles of end 15 and 18. Once these triangles 15 and 18 are approximated, heat their flaps 19.

Then, said container part is placed 100 with the vertex O facing down, in a filling mold M which It has substantially the same hollow shape. Free edges peripherals 19 of the container part 100 advantageously protrude of the filling mold M.

Once positioned, the container part 100 is filled with a pasty food product P based on cheese molten. The filling is carried out to a height less than that of the pyramid, that is to say substantially at the level of the upper surface M mold or slightly below, to be able to perform the Next stage of closing the pyramid. Said filling stage is illustrated in figures 6 and 7.

Once the pasty product is a little less fluid and less hot, a film 115 of heat-sealable aluminum and, for example, square section, whose shape is substantially identical to that of the part section upper part of the hollow part of the mold M, on said product P for form the bottom, that is the base of the pyramid. This stage is illustrated in figure 8.

After placing the background film 115 on the pasty product P, the peripheral free edges are folded  19 of the pyramid, and heat sealed on the bottom 115, as illustrated in figure 9. The edges 19 can be folded successively by pairs of opposite edges, as illustrated in Figures 10 and eleven.

According to the embodiment variant of Figure 4, in which the base sheet 10 includes three triangles instead of four, the differences with the procedure thus described affect mainly to the shape of the mold M, in pyramid with base triangular, the shape of the bottom sheet 115, which is a triangle equilateral, and the flaps 19 that fold one after another consecutively in triangle.

To have access to the pasty product based on processed cheese, the user uses the organ (s) of tearing by pulling its starter tab in order to open the individual pyramidal container 1 manufactured by means of procedure described above. In this way, the opening of the individual pyramidal container with square base of figure 12 and individual triangular base pyramid container of figure 13 se effect by breaking substantially a full face of said pyramid, even two when there are two organs of tearing, as illustrated in figure 2. In this mode particular embodiment, the opening is called the type "butterfly", since two faces open from its base towards the vertex O. In the embodiments illustrated in Figures 14 at 17, the opening is called sequential, since it goes from one side to another in a single start-up stage.

However, it should be understood that such examples are included by way of illustration of the object only of the invention, of which they do not constitute in any way a limitation. Therefore, it is possible to combine different types of plucking organs with each other. Especially it is possible combine a solution in which the pyramid is endowed with a petal-shaped starter on a first face, and of a Y-shaped starter in a second face.

It is also possible to provide a multitude of molds mounted on a stand for mass production by middle of an automated chain.
