Description

INFUSION PACK FOR A RESPECTIVE FOOD PRODUCT

The present invention regards an infusion pack for a respective food product.

Said product is, in particular, shaped as a food product for infusion, such as coffee or the like.

Infusion packs have been known for a respective product for infusion, in particular as loose powder coffee and which are able to be used in a suitable apparatus for making a respective drink.

Said known packs have an external wrapping defining a chamber for containing the product and means which are able to define a respective passageway for introducing heated water inside the wrapping and for the going out of the brewed drink from the same wrapping.

In particular, infusion packs are known which are shaped as a capsule, in rigid plastic material, having a wide housing chamber for the infusion product, which is housed therein in powder in loose condition.

Dimensions of such known packs are excessive, with waste of material for the relative realization and of material for realizing the corresponding packages. Furthermore the treatment of such a loose product, during the packing steps, is not particularly easy and produces undesired powders and dirt on the packing machines.

Moreover, infusion packs are known which are defined by opposite film or pellicle sheets that tightly contain and maintain compact the said product for infusion, always in loose condition.

These flexible material packs are, however, difficult to be made, since they need complex and costly apparatuses for treating such a loose product to be hermetically packed and with high risks of loss of product during the preparation steps, besides producing undesired powders and dirt on the same packing machines.

Furthermore, both the above referred packs do not provide, and anyway they would not be suitable, to enable a waste separation of the various components of the pack.

In fact, with these known packs, once used, the coffee cannot be put in the container provided for collecting organic wastes and, similarly, the containment capsule or wafer cannot be binned in the corresponding container, for example in the container provided for collecting plastic material.

In practice, with these known packs, the used product must be binned inside the container for collecting the unseparated fraction of the urban waste, with consequent risk that an ecological damage occurs in the successive disposal step.

With the present invention it is intended to propose a new solution which is alternative to the solutions known till now and/or in particular it is intended to get round one or more drawbacks and/or above referred problems, and/or to satisfy one or more above referred exigencies or anyway which can be derived from what is mentioned above.

Thus, an infusion pack for a respective product is provided, said product being in particular shaped as a food product for infusion, such as coffee or the like, said pack having a wrapping defining a containment chamber of the product and being able to be provided with means suitable to define a respective passageway for introducing inside the wrapping and for the going out from the same wrapping of an infusion fluid or liquid, characterized in that the pack comprises a compact slab of said product for infusion which is housed inside said wrapping, and in that said wrapping defines a housing chamber which has a volume coinciding or substantially coinciding with the one of said compact slab.

In this way, it is possible to realize an infusion pack in a particularly easy way and possibly with saving of packing material.

In fact, having available a compact slab of material its handling and insertion inside the wrapping of the pack is particularly easy. Moreover, the pack can be made with the material strictly necessary for containing a product for infusion which occupies the particularly reduced volume defined by such a compact slab of product.

This and other innovative aspects of the invention are, anyway, exposed in the following claims, the technical characteristics of which can be found, together with corresponding obtained advantages, in the following detailed description , illustrating the purely exemplificative and not limitative embodiments of the invention, and which is made with reference to the united drawings, wherein:

[26] figure 10 and 1 1 illustrate an exploded section view of a third and fourth embodiment of the infusion pack according to the invention, respectively.

[27] In the attached figures from 1 to 7, is illustrated a first preferred embodiment 10 of infusion pack for a respective product 15, in the figures 8 and 9 is illustrated a second preferred embodiment 100 of infusion pack for a respective product 15, in the figures 10 and 1 1 a third embodiment and a fourth embodiment 200, 300 respectively, for a respective product

215, 315.

[28] Such a product is in particular a food product for infusion, such as coffee or other product for infusion, for example tea, cacao, chocolate, camomile tea, tisane, barley, preparation for broth, for making a corresponding drink.

[29] The present infusion pack can be used in a suitable apparatus A, illustrated in figure 6 where the pack 10 is suitably inserted inside a respective profiled housing seat, that is, as illustrated, through a respective profiled split F defining an access to said housing seat.

[30] By effect of the specific operative way of the apparatus, an infusion liquid, preferably as heated water, passes through the pack so that the product infuses itself in the same infusion liquid and it is then transported and discharged in a suitable container, or cup, C, in view of the consumption of the drink by the user.

[31] As illustrated, the respective pack 10, 100, 200, 300 has a respective containment wrapping 1 1 , 1 11 , which defines a respective housing chamber 13 of the product for infusion 15.

[32] The wrapping 1 1 , 11 1 can have means suitable to define a respective passageway of the body of the wrapping for introducing inside the same wrapping a fluid or liquid for infusion and for the going out from the same wrapping of said fluid or liquid for infusion charged of the infused product, as will be, anyway, better described in the following of the present description.

[33] In particular and preferably, said fluid or liquid for infusion is heated water.

[34] Advantageously, the pack 10 comprises a product for infusion which has the shape of a compact slab 15 of said product for infusion and which is housed inside said wrapping 1 1 ,

1 11.

[35] With further advantage, the said wrapping 1 1 , 1 1 1 defines a housing chamber 13 which presents a volume coinciding or substantially coinciding with the one of said compact slab 15.

[36] The present slab of food product to be infused is defined by a plurality of particles or powders reciprocally aggregated of said food prod uct to define a compact and substantially rigid body, which is suitable to maintain its own shape.

The predetermined portion of product in the present slab configuration presents a minimal volume and, therefore, lower than the one it would present in loose condition. Thanks to the present slab, packs having particularly reduced dimensions can be obtained.

The present slab could be made as disclosed in the international patent application

WO2007080492 and in the Italian patent application BO2007A000829, the content of which, through the present reference, is to consider as being integral part of the present description.

In practice the present slab is preferably obtained from a portion of roasted coffee, in powder or in small granules, which is introduced inside a respective mould at which is applied a ultrasonic tool device, which can be of known typology.

The process provides, advantageously, that an aggregating agent is added, in particular a liquid, specially consisting in water, to said powder or granular product, so as to favour the aggregation of the particles of said product.

Then, a predetermined portion of product is arranged in said mould. After that, energy is supplied to said predetermined portion of product in such a way as to aggregate, or let adhere, the particles of said product.

In a particularly advantageous way, said energy is supplied as mechanical vibrations, in a preferred way as ultrasonic mechanical vibrations.

A slab is obtained wherein the particles of product remain rather distinct to each other, adhering, however, to each other, so as to define a compact, or aggregated, configuration of said powder or granular product.

Said agent is, in particular, water and is added in quantity varying from 0, 1 % to 20% in weight of said predetermined portion. Preferably, said agent, in particular water, is added in varying quantity from 3% to 10% in weight of said predetermined portion.

Moreover, it is provided to supply energy as mechanical vibrations, which present a vibration frequency varying from 15.000 to 50.000 Hz, and preferably, in the ultrasonic field, equal to 20.000 Hz.

Furthermore, it is provided to supply to said predetermined portion of product a quantity of energy comprised between 1 00 and 5.000 Joule, preferably a quantity of energy comprised between 700 and 2.000 Joule, and in a particularly preferred way substantially equal to 1.500 Joule.

It has been verified that at least part of the aggregation water evaporates during the step of supplying energy to said predetermined portion of product, in particular during said step of supplying mechanical energy.

As can be deduced from figure 1 , with L is marked for ease of description a longitudinal development axis of the present pack.

In its turn, as illustrated , the respective wrapping 1 1 , 1 1 1 has respective extreme transverse walls or panels 12a, 14a, or 1 12a, 114a.

In particular, advantageously, the respective pack 10, 100, 200, 300 comprises a compact slab 15 of said product for infusion which is housed inside said wrapping 1 1 , 1 1 1 , the which wrapping 1 1 , 1 1 1 has the internal face of the opposed extreme transverse walls 12a, 14a or 1 12a, 1 14a, which engages against the respective extreme transverse face 15a, 15b of the said slab 15. Said internal face of the transverse wall being marked in the first two embodiments by the references 12', 14', and 1 12', 1 14'.

Even if the present embodiment is a particularly preferred embodiment, it would be anyway, also, imaginable a solution wherein at least one extreme transverse wall engages against the respective extreme transverse face of the compact slab 15 of product for infusion.

These respective transverse walls or faces preferably lie on planes substantially perpendicular to said conventional direction L.

As illustrated, the respective transverse wall 12a, 14a, 1 12a, 1 14a of the wrapping presents a shape matching the extreme transverse face 15a, 15b of the slab.

In practice, the respective transverse wall of the wrapping contacts the entire extreme transverse face 15a, 15b of the same slab.

As illustrated, the compact slab 15 comprises respective extreme transverse faces, in particular plan form and circumferential, 15a, 15b and a peripheral face 15c which extends longitudinally between the said extreme faces 15a, 15b and which, in particular presents a cylindrical conformation.

As illustrated, the longitudinally extreme transverse faces 15a, 15b are preferably parallel to each other and lie on planes perpendicular to the longitudinal direction L according which the lateral cylindrical surface 15c of the same slab of powder or granulate product extends.

In its turn, the respective wrapping 1 1 has respective extreme faces 12a, 14a, which are preferably parallel to each other and are suitable to contact the respective preferably plane transverse faces 15a, 15b of the slap of product for infusion 15.

Moreover, advantageously, the respective wrapping 1 1 , 1 1 1 has a lateral peripheral wall

12b, 14b, or 1 12b, 1 14b, the internal face 12", 14", 1 12", 1 14" of which engages at least partly, or completely against the lateral peripheral face 15c of the slab.

As illustrated, in the first preferred embodiment 10, the said containment wrapping 11 is a rigid, or substantially rigid, cover preferably in plastic material, while, in the second preferred embodiment 100, the containment wrapping 1 1 1 is a flexible wrapping realized in a corresponding film or pellicle, or other material such as aluminium pellicle, layered plastic film or other.

Both the said first and second embodiments 10, 100 comprise a first and a second portion 1 2 , 14, respectively, 112, 114, facing each other and containing between them a respective compact slab 15 of said product for infusion.

In particular, in the embodiments disclosed, the respective compact slab 15 extends beyond the extreme edge of a respective portion 12, 14, 1 12, 1 14 of the pack inside the facing portion 14, 12, 1 14, 1 12 of the respective wrapping.

As illustrated, the first preferred embodiment 10 has a wrapping comprising a respective body shaped as a cup 12, in particular a first and a second body shaped as a cup 12, 14, preferably in plastic material, and making in the whole a containment cover for said compact slab 15.

In practice, a first and a second body shaped as a cup 12, 14 define respective half- covers facing each other and containing, or wrapping, the said compact slab 15.

In practice, the respective cup-shaped body 12, 14 for defining the containment cover of the present infusion pack, is made in plastic material, rigid or semi-rigid, which is obtained through moulding or thermo-moulding, injection or blow moulding of a corresponding material or material film.

As illustrated, in particular in figure 3, the respective cup-shaped body 12, 14 presents a respective bottom wall 12a, 14a, having a flat conformation, and a peripheral wall longitudinal or perpendicular to the respective bottom wall, marked with the reference 12b, 14b.

According to the preferred embodiment illustrated here, the bottom faces or walls 12a, 14a of the half-covers, or portions, 12, 14 of the wrapping present a circular peripheral profile and the respective longitudinal or lateral peripheral wall 12b, 14b has a cylindrical general conformation.

Furthermore the said covers 12, 14 preferably have the same longitudinal height and in particular are totally identical to each other and can therefore be obtained from a same mould, or from identical moulds. Alternatively, as shown in figure 10 illustrating the third embodiment, the covers 212, 214 can by substantially identical, but with a curved bottom, so as to contain a correspondingly shaped compact slab 215. Still, as illustrated in figure 1 1 for the fourth embodiment, the covers 312, 314 can be shaped differently, one being provided with a flat bottom, the other one with a curved one. The product slab 315 is in this case shaped accordingly. I n both cases, the quantity of product which can be contained in the wrapping is increased, owing to the curved shape.

In practice, the respective cover 1 1 can be made of a first and a second portion 12, 14, which are preferably extended in a mirror-like way, profiled with respect to the reciprocal union plane. [69] In practice, the respective cup bodies 12, 14 have a longitudinal axis 'U and are, in the pack, positioned coaxially with respect to this axis.

[70] In its turn, the wrapping 1 1 1 of the second preferred embodiment has a respective sheet

1 12, 114 of suitable film or pellicle, which matches and winds around the compact slab 15.

[71] In particular, the wrapping 1 1 1 of the second preferred embodiment comprises a first and a second sheet 1 12, 114, in suitable film or pellicle, facing each other and winding about the interposed compact slab 15.

[72] As illustrated, in all embodiments the wrapping 11 , 11 1 has a transverse peripheral lip 16,

1 16, that radially extends from the lateral peripheral wall 12b, 14b, 1 12b, 1 14b of the respective wrapping, towards the outside of this wall of the wrapping.

[73] In this way, an external profiled surface is supplied, suitable to match the profile of a corresponding seat "F" for introducing or housing in the infusion machine "A".

[74] The said peripheral lip 16 is preferably parallel to the transverse extreme walls 12a, 14a of the respective wrapping and extends perpendicular with respect to the corresponding peripheral wall 12b, 14b of the wrapping.

[75] The respective portion 12, 14, 1 12, 1 14 of the respective wrapping 1 1 , 1 1 1 has a peripheral lip 12d, 14d, 1 12d, 114d protruding radially towards the outside and suitable to define means for associating with the other portion of the pack.

[76] As illustrated, the respective lips 12d, 14d, 1 12d, 1 14d of the respective first and second portion 12, 14, 1 12, 1 14 extend peripherally for the entire circumferential extension of the respective portion.

[77] As is evidenced, in particular in figure 3, the respective profiled cover 12, 14 comprises a lateral peripheral wall 12b, 14b, which extends from the bottom peripheral wall 12a, 14a. The said external peripheral lip 12d, 14d extends from the end of the lateral wall 12b, 14b which is opposite the one wherein is provided the said bottom wall 12a, 14a.

[78] Advantageously, as can be deduced from the figure 7, the wrapping 1 1 , and possibly also the wrapping 1 1 1 , can be opened, after use or infusion, in particular to allow to put advantageously at waste the slab 15 separately with respect to the wrapping 1 1.

[79] Anyway, the wrapping 1 1 can be opened to allow the going out of the said slab 15 from the same wrapping.

[80] In greater detail, the first and the second portion 12, 14 of the wrapping can be separated, at least partially, from each other to define an outlet mouth 21 of the slab 15, as can be deduced from the figure 7.

[81] The respective cup shape body 12, 14 presents, therefore, a respective peripheral lip 12d, 14d protruding radially towards the outside from the extreme longitudinal edge of the lateral peripheral wall 12b, 14b, which is opposed to the one at which extends the bottom wall 12a, 14a of the cup body. Therefore, the first and second portion of the wrapping 12, 14, 1 12, 1 14 have respective peripheral lips 12d, 14d, 1 12d, 1 14d, protruding radially and which, in the pack, are matching each other and between which are provided respective union means.

In practice, union means between the first and the second portion of the wrapping 12, 14, 1 12, 114 are provided between respective peripheral lips 12d, 14d, 1 12d, 1 14d protruding radially and matching said first and second portion.

In practice, union means are provided between the first and the second portion which union means are particularly provided as adhesive means of a corresponding adhesive layer.

The union means between the first and the second portion are in particular provided as releasable union means, for example mechanical coupling means as matching male and female profiles.

In this manner, it is possible to separate, at least partially between them, the first and the second portion of the wrapping, in view of the going out of the slab from the respective cover and of the putting at waste of the components of the pack in different containers, and for example in a container for biologic waste, the slab, and in another container the wrapping of the pack.

Alternatively the slab could be used in the apparatus without the wrapping. Therefore its separation from the wrapping can directly serve for the use of the product in the apparatus A, and not only for its putting at separated waste.

In practice, between the first and the second portion 12, 114 at the respective union lip, is provided a union layer which has a traction resistance lower than the resistance of the material which defines the portion of the wrapping.

Therefore, exerting a traction action, in reciprocal going away of both the portion 12, 14 of the wrapping, one obtains the reciprocal detachment of these portions and the access to the internal chamber 13 for housing the slab, which so can be easily made going out through the mouth 21 which is obtained through this separation operation. In practice, it suffices to use as union layer a union layer which is suitable to allow the ease detachment of the surface which supports it.

In practice, the releasable union means are provided between the facing peripheral lips of the first and of the second portion of the wrapping.

Are, also, advantageously, provided means 18a, 18b for opening the wrapping 1 1.

Analogous opening means can be provided also on the wrapping 1 1 1 of the second preferred embodiment, also if they are not particularly illustrated in the corresponding figures.

The said means for opening the wrapping are provided as grip means, in particular by the fingers of the user, and in particular as first grip means 18a provided on a portion 12 of the wrapping and as second grip means 18b provided on a second portion 14 of the same wrapping.

[94] The said opening means are disguised as a respective tang 18a, 18b, which is provided on the respective portion 12, 14 of the wrapping.

[95] As can be deduced from the figures, the respective tang extends from the peripheral lip

12d, 14d of the respective portion 12, 14 of the wrapping.

[96] Moreover, as can be deduced from figure 1 , the respective grip tangs 18a, 18b of the portions matching each other are at each other, in particular they are longitudinally aligned to each other.

[97] As illustrated, the respective grip tangs 18a, 18b of the portion associated to each other

12, 14 of the wrapping are overlapped to each other.

[98] The said tangs 18a, 18b of the said portion associated to define respective wrappings are lacking of adhesive layer and so are not united during the union step joining the said first and second portion 12, 14 to define the respective wrapping.

[99] Advantageously, the means suitable to define a passageway for introducing a liquid for infusion and the going out of an infused liquid, are provided as holes already realised on the respective transverse wall 12a, 14a of the wrapping or realised through the insertion in the apparatus A. These hole means, or holes, are however not particularly illustrated in the attached drawings.

[100] According to another embodiment the said means suitable to define a passageway for the inlet of the liquid for infusion and for the outlet of the infused liquid from the inside of the wrapping can be provided as a transverse wall 12a, 14a, that is of the entire wrapping, which is in suitably pierceable or lacerable material, through corresponding means, in particular pierceable in the infusion machine, for the direct passage of liquid inside and outside the wrapping and for the passage of means, such as needles for injecting said liquid.

[101] In practice, in the present external wrapping, said first and second portion 12a, 12b are separated portions and united to each other to define the present pack.

[102] An advantageous process for making the present pack 10 can be highlighted in figure 5.

An analogous process could be provided also for making the above referred packs 100, 200, 300. The process provides for prearranging a first portion of the wrapping, positioning a compact slab of material in infusion on the said first portion of the wrapping, positioning a second portion of the wrapping at, or above, the first portion of the wrapping, containing between these latter the compact slab of material for infusion 15, and, at last, to unite to each other the said first and second portion of the wrapping housing the compact slab 15 of material in infusion.

[103] Anyway it must be understood that the present body of the slab could be made of any adapted and desired shape and anyway adapted to be housed inside the pack.

The so conceived invention is susceptible of obvious industrial application. The person skilled in the art will be able to further imagine numerous variants and/or modifications to be made to the invention illustrated in the specified preferred embodiment, at the condition of remaining in the frame of the inventive concept, as widely exposed. In particular, the person skilled in the art will be able to easily imagine further preferred embodiments of the invention which comprise one or more of the above indicated characteristics. Furthermore, it must be understood that every detail can be substituted by technically equivalent elements.
