Definitions
- the present invention relates to prepackaged charges for the preparation of beverages, intended for use in suitable machines; in particular, the invention relates to a self-protected prepackaged charge for the preparation of beverages, and which is capable of directly dispensing the prepared beverage.
- This type of solution designed typically for coffee, provides a system that forces the charge to reach a given pressure before dispensing the beverage, but does not provide the means that constitute a barrier to oxygen, and therefore to the degradation of edible materials. within the charge itself.
- An object of the present invention is therefore a prepackaged charge of edible material for the preparation of beverages, comprising a vessel-shaped container body, provided at the open end of a closing wall made of an air impermeable material, and provided on the bottom wall of means for dispensing the prepared beverage, a second wall made of material impermeable to air being provided near the bottom wall; said second wall impermeable to air, being made with at least one layer of thermoplastic material facing inwardly of the container body, a support made of thermoplastic material being provided inside said container body, intended to be coupled by welding to said layer of thermoplastic material of said second wall, said welding being performed on a polygonal path, with at least two angles of less than 90°.
- said support made of thermoplastic material is a wall made of a filter material of polymeric yarn based on a thermoplastic polymer.
- said support is a disk-shaped element, which can be provided in the central portion with a polygonal relief projecting towards the said second impermeable wall.
- the dispensing means comprise a dispensing nozzle made in one piece with the bottom wall of said container body, and formed with a poly-lobed profile by thermo-mechanical deformation.
- FIG. 1 illustrates a first embodiment of the prepacked charge according to the present invention, in a phase of its production.
- the vessel-shaped container body is designated with the numeral 1, and provided with the lateral frustoconical wall 101 which has, at the open end, a radial flange 111 projecting outwards, while the other end has a bottom wall 201, provided with a funnel-shaped portion 211, at the center of which the nozzle 221 is positioned.
- At the funnel-shaped portion 211 there is a wall of air-impermeable material 231, provided with a layer of thermoplastic material facing the inside of the container body 1.
- the wall 231 there is a wall of filter material 241 made of a thermoplastic material fiber; the wall 231 and the wall 241 are coupled together thanks to the punch 30, with a triangular section, as it appears from the top plan view in figure 1A , overheated and brought into contact with the wall 231, while the wall 241 is contact with the contrast pin 40, cold.
- Figure 2 shows the container body 1 of the prepacked charge of Figure 1 , at the end of the processing illustrated therein.
- equal parts correspond to equal numerals; in the center of the wall 241 and of the wall 231, coaxial and concentric to each other, the triangular welding zone 251 has been formed, placed directly above the dispensing nozzle 221.
- FIG 2A shows an enlarged detail in longitudinal section of the container body of Figure 2 ; as can be seen, following the combined action of the punch 30 and of the pin 40, the welding zone 251 is given by the interpenetration of the materials which make up the filtering wall 241, in particular a non-woven fabric made of polymeric fiber, such as for example polyester, and the layer 2321 in thermoplastic polymer, for example polypropylene, which is included in the wall 231 impermeable to air; said layer 2321 is coupled with an aluminum layer 2311, which at the impact zone of the punch 30 shows a thinning 2331.
- the materials which make up the filtering wall 241 in particular a non-woven fabric made of polymeric fiber, such as for example polyester, and the layer 2321 in thermoplastic polymer, for example polypropylene, which is included in the wall 231 impermeable to air; said layer 2321 is coupled with an aluminum layer 2311, which at the impact zone of the punch 30 shows a thinning 2331.
- Figure 3 illustrates a second embodiment of the prepackaged charge according to the present invention, in a processing step thereof, similar to that illustrated in Figure 1 ; to the equal parts correspond equal numerals; in the figure, it is noted that on the end wall 201, an annular support body 301 of thermoplastic material is positioned and suitably coupled, provided with the arms 311 which centrally support the portion 321, coaxial with the dispensing nozzle 221, and provided with the axial polygonal protrusion 331, facing the impermeable wall 231, in its turn provided with a layer of thermoplastic material which interacts with the relief 331 of the central portion 321 of the annular body 301.
- Figure 3A is proposed a view similar to that of Figure 2A , referred in this case to a longitudinal section of the body of the prepackaged charge at the end of the processing step shown in Figure 3 .
- a portion of the relief 331 protruding from the portion 321 coaxial with the dispensing nozzle, not shown in this figure, of the supporting annular body made of thermoplastic material is welded with a part of the layer 231 of thermoplastic material 2321 of the wall 231, impermeable to air thanks to the aluminum layer 2311; also in this case the action of the punch 50 resulted in a thinning 2331 of the wall 231.
- Figure 4 shows the supporting member301 of the container body of Figure 3 , in plan bottom view, so as to make the triangular shape of the relief 331 protruding from the central portion 321 of the body 301 shown better.
- Figure 5 is shown, in an enlarged detail, an executive variant of the supporting member, in which the relief 351 is in the shape of a star.
- Figure 6 shows a plan view from below of a further variant of the container body 1 of the prepackaged charge according to the present invention; even in this case the numeral equals correspond to the same parts.
- the figure highlights the fact that the dispensing nozzle 221 comprises an outlet edge 2211 with a three-lobed tapered profile, thus being able to provide the nozzle 221 of a means for diffusing the flow of the beverage to be dispensed.
- the container body 1 comprises an air-impermeable wall 231 which, in the manner best illustrated in Figure 2A , consists of a layer of thermoplastic polymeric material and an aluminum layer.
- the welding which Is carried out with the punch 30 between the wall 231 and the wall 241, has the object of creating a constraint zone which, by tearing or pulling, causes the fracture of the wall 231 which, due to the presence of aluminum, is relatively more fragile than wall 241 in filter material.
- the welding path is made in such a way as to create a welding zone in which there are points where the structural stress is accentuated, as evidenced by the graph of the simulation attached in Figure 7 , in which the lighter areas are those subjected to the greatest stress.
- the vertexes of the welding area appear to be the points where the stress of the wall with respect to the pressure load appears worse absorbed, and therefore in those points, with the increase of pressure inside the container body, it will be reasonable to expect the wall 231 to break.
- the aluminum layer 2311 of the wall 231 is affected by the pressure of the punch, and this thinning, which in the figure has been exaggerated but which in any case occurs, accentuates the fragility of the wall in correspondence of the welding area 251, also in consideration of the changed mechanical properties of the same welding zone, which are affected by the features of both components.
- the executive variant of Figure 5 allows the introduction of a polygonal relief of a different shape; the number of acute angles is increased, and therefore that of the stress points in which the break more simply occurs.
- the choice of a polygonal welding path with angles smaller than 90° derives from the evaluations based also on the simulation of Figure 7 ; the equilateral triangle welding path is the simplest and most balanced one, but the star also has undoubted advantages with a minimum structural complication of the support body, i.e. the welding punch.
- the openings which will form on the wall 231 at the corners of the welding area will be substantially triangles with a vertex facing the dispensing nozzle, but arranged on inclined planes with respect to the plane of the wall 231 before the infusion. Consequently, the flows of the resulting beverage will be directed towards the funnel wall 211 of the bottom wall 201, rather than directly towards the nozzle 221.
- the flow should therefore be sufficiently widespread even in the absence of specific devices inserted inside the container body.
- the prepackaged charge according to the present invention is therefore capable of directly dispensing the beverage prepared therein upon the achievement of a given pressure value, without there being complex means of drilling therein, and with decidedly very reduced procedural and structural constraints.
