Description
- The present application claims priority to Italian patent application GE2010A000009 filed on Jan. 26, 2010 and incorporated herein by reference in its entirety.
- The present disclosure relates to devices for preparing alimentary beverages, and particularly to a pre-charged ground coffee capsule.
- For many years now the preparation of coffee, both for domestic use and for professional use, both in machines requiring manual preparation and in automatic and semi-automatic machines, involves the use of pre-charged capsules or pods of varying shape and design which normally have a dual function, the primary function being that of allowing preparation of the coffee infusion without using coffee powder in loose form, so that the working process is “cleaner” and general maintenance is simpler.
- A major problem with regard to the choice of materials and the structure to be given to the pre-charged capsule or pod, consists in achieving a suitable compromise between robustness and efficient use; in other words, if, on the one hand, the water-permeable materials such as filter paper, non-woven fabric and the like ensure an effective use of the capsule or pod, on the other hand they give rise to notable defects both from the point of view of storage and as regards positioning inside the filter holder.
- Document EP1997748, in the name of the same Applicant, describes a pre-charged ground coffee capsule comprising a container body with a polygonal cross-section, and preferably a circular cross-section, which is made of a liquid-impermeable material, open at one end and provided on the bottom wall with a large axial opening, two walls of liquid-permeable material being arranged, respectively, above said open end and along said bottom wall; said impermeable material comprises a support layer made of metallic material and a layer of thermoplastic material facing the inside of said container body, said permeable walls being joined to said container body by means of said layer of thermoplastic material, an outwardly projecting radial flange being provided at said open end of said container body.
- This type of pre-charged capsule solves many of the problems associated with the prior art, but nevertheless has a number of drawbacks. In particular, the structure so designed, although being effectively configured, is somewhat weak and therefore poses problems from the point of view of packaging and use by the end user. Comparing this type of pre-charged capsule with those made entirely of thermoplastic resin, it is entirely clear that the latter have better handling properties and are easier to use both in espresso coffee machines and in traditional “moka” or similar coffee machines, but have the problem that they require further packaging, preferably in an inert atmosphere, in order to preserve the aroma of the coffee powder.
- In accordance with several embodiments of the present disclosure, a pre-charged ground coffee capsule is provided which, on the one hand, is able to preserve the quality of the product contained therein and, on the other hand, has a structural strength which allows it to be managed easily both during storage and during use.
- According to an aspect of the present disclosure, a pre-charged ground coffee capsule is provided, comprising a preferably cylindrical or frustoconical container body made of a metal foil material combined with a film of thermoplastic material, said container body comprising a structural stiffening member provided with a plurality of through-openings and arranged in a plane which is substantially perpendicular to the longitudinal axis of said container body. Said stiffening member has arranged thereon a water-permeable layer of filter material facing the inside of the container body.
- According to a further aspect, said stiffening member includes a substantially disc-shaped element comprising a peripheral ring and a plurality of radial elements converging toward the center and equally spaced from each other. A recess communicating with the aforementioned openings is preferably formed in the center of said member.
- Alternatively, said stiffening member can be provided with a peripheral wall which is perpendicular to the plane of said stiffening member, said wall being continuous or discontinuous. Furthermore, such a wall can be provided with an outwardly projecting radial flange.
- In a further embodiment, the bottom wall of said stiffening member can be made so as to be deformable and it is provided with means adapted to perforate the wall of said container body at the outwardly-facing side thereof.
- Alternatively, said stiffening member is positioned externally of said container body and it is provided with means adapted to perforate the wall of said container body at the outwardly-facing side of its bottom wall. In a preferred embodiment, said stiffening member is provided with a plurality of channels formed at the internal side-wall thereof and communicating with the bottom wall.
- Other advantages and features will be apparent from the following detailed description of certain embodiments of the same which are provided by way of illustration, and not by way of limitation, with reference to the accompanying drawings in which:

FIG. 1 shows a first embodiment of the pre-charged capsule according to the present disclosure; 1 denotes the container body of the pre-charged capsule according to the disclosure. Saidcontainer body 1 is provided with abottom wall 101, acontinuous side wall 111 and aclosing surface 201; both thecontainer body 1 and theclosing surface 201 are made of a metal foil material, such as aluminium or the like, combined with a layer of a thermoplastic resin, such as polyethylene or the like, which allows them to be joined together. Thestiffening member 2, which has acentral cavity 102 and on which a layer offilter material 202 is placed, is arranged along thebottom wall 101 of thecontainer body 1. As can be seen more clearly fromFIG. 2 , which shows a cut-away perspective view of the pre-charged capsule, themember 2 comprises anannular element 302, which has the same cross-section as thebottom wall 101 of thecontainer body 1, and a plurality ofradial elements 312 converging towards thecavity 102 and forming theopenings 322 directed towards thebottom wall 101 of thecontainer body 1. -
FIG. 3 shows a second embodiment of the capsule according to the disclosure; the same parts are indicated by the same numbers. In this case, thestiffening member 3, in addition to comprising anannular element 303 and the radial elements 313 (seeFIG. 4 ) in a similar manner to that described for the embodiment inFIGS. 1 and 2 , also has a continuousaxial wall 403 which is arranged so as to actually contact with theside wall 111 of thecontainer body 1. Thelayer 203 of filter material is placed on the surface of themember 3. - Entirely similar in nature is the embodiment shown in
FIGS. 5 and 6 , where theaxial wall 404 of thestiffening member 4 has an outwardly projectingradial flange 414 onto which theclosing surface 201 of the pre-charged capsule is joined. Otherwise, thestiffening member 4 has theannular element 304 and theradial elements 314 converging towards thecavity 104 and forming theopenings 324 on which thelayer 204 of filtering material is positioned. - In the variant embodiment shown in
FIGS. 7 and 8 , thestiffening member 5 hasaxial webs 405 which are joined at one end to theannular element 305, placed in contact with thebottom wall 101 of thecontainer body 1, while at the opposite end they are connected to theflange 415 projecting radially outwards. In this case also, thestiffening member 5 has theannular element 305 and theradial elements 315 converging towards thecavity 105 and forming theopenings 325 on which thelayer 205 of filtering material is positioned. - The embodiment in
FIGS. 9 and 10 shows the stiffening member 6 arranged in contact with theclosing surface 201 instead of with thebottom wall 101. As can be noted fromFIG. 10 , although the arrangement is shown as being completely overturned with respect to that of the devices of the embodiments previously shown and described, the characteristic features of the member 6 are in fact entirely the same. Said member 6 has theannular element 306 and theradial elements 316 converging towards thecavity 106 and forming theopenings 326 on which thelayer 206 of filtering material is positioned. As a particular feature, the member 6 has the outwardly projecting radial flange 406 which practically acts as a support for theclosing surface 201 on the one hand, and for the outgoing edge of theside walls 111 of thecontainer body 1 on the other hand. -
FIG. 11 shows a further embodiment of the pre-charged capsule according to the disclosure. In this embodiment, thestiffening member 7 is provided with acontinuous side wall 107 similar to that of the embodiment according toFIGS. 5 and 6 ; thebottom wall 207 is formed with acentral portion 217 substantially shaped as a dome and in the manner of an undulating membrane. The more rigidaxial portion 227 has formed therein thenibs 237 which project axially outwards. Thecontainer body 1 encloses themember 7, and theclosing surface 201 is mounted onto the edges of the radial flange 117 projecting from theside wall 107.FIG. 12 shows, with reference to the same numbers, the structure of thedome portion 217 and the more rigidcentral portion 227 of thebottom wall 207, as well as the series ofholes 247 formed in thedome portion 217. -
FIG. 13 shows a further alternative embodiment of the present disclosure. In this case, thecontainer body 1 is inserted inside themember 8 which in this case imparts rigidity to the container body itself, supporting it externally. Thebottom wall 101 of thecontainer body 1 faces thebottom wall 208 of themember 8, which is provided with a plurality of through-holes 218 andpyramidal reliefs 228. InFIG. 14 it is possible to note the arrangement of thebottom wall 101 of thecontainer body 1 very close to thepyramidal reliefs 228. -
FIG. 15 shows a further embodiment of the present disclosure, and particularly a variant of the embodiment shown inFIGS. 13 and 14 . In this case also, the stiffening member 9 is located outside of thecontainer body 1, and thebottom wall 209 of the stiffening member also haspyramidal reliefs 219 in a similar way to that envisaged in thewall 208 of the stiffeningmember 8 as shown in the embodiment according toFIGS. 13 and 14 . In this case, however, theside wall 109 and theflange 119 connected thereto have grooves 129 which connect thebottom wall 209 to the environment outside of the pre-charged capsule. As can be noted from the exploded perspective view inFIG. 16 , thecontainer body 1 is arranged inside the stiffening member 9 so that its outer walls create, in cooperation with the grooves 129, channels communicating with the bottom of the member 9. - The operating principle of the pre-charged capsule according to the present disclosure will become clear from the description below. As already mentioned, a pre-charged capsule totally made of a metal foil material such as aluminium or the like, internally lined with a plastic material, provides a light and impermeable packaging, but on the other hand is an object which is not very strong from a structural point of view and which may give rise to problems both during storage handling operations and during final use. The insertion of a stiffening member inside the capsule enhances the management thereof as regards these two different aspects; if in the embodiment according to
FIGS. 1 and 2 , the stiffening member has a certain prominence in the structure of the pre-charged capsule, in the embodiments according toFIGS. 3 , 5 and 7, thecontainer body 1 and the closing surface constitute in fact the sealing casing of a pre-charged capsule which has a structure made mainly of plastic, but which takes advantage from the fact of being completely lined by a container which isolates it from the external environment. Practically, thecontainer body 1 in the embodiments according toFIGS. 3 and 5 ceases to be a container body in the full sense, while it is still partly so in the embodiment according toFIG. 7 , and becomes instead a lining which allows the pre-charged capsules to be configured without the need for further packaging which is normally added in order to preserve the integrity of the coffee aroma. In fact, thecontainer body 1 and theclosing surface 201 may be sealed together in a controlled atmosphere, for example an inert-gas atmosphere, so that the contents of the capsule are preserved without further measures. - The embodiment according to
FIGS. 11 and 12 has, in addition to the features of the embodiments shown in the other figures and described above, also provides a characteristic feature relating to the system for preparing the coffee infusion. In fact, thecentral portion 217 of thebottom wall 207 is designed so as to be sensitive to variations in pressure caused by the entry of hot water under pressure inside thecontainer body 1 and, therefore, its expansion causes the centralrigid portion 227 to come into contact with thebottom wall 101 of thecontainer body 1 and, in particular, openings are formed in the bottom wall itself via thenibs 237. At this point, once the coffee infusion has passed through theholes 237 in thewall 207 of the stiffeningmember 7, it can percolate outside through the opening(s) formed in thecontainer body 1 by the action of thenibs 237 projecting from theportion 217 of thebottom wall 207. - The embodiments in
FIGS. 13 , 14 and 15, 16 are based on a functional concept slightly different from that described hitherto. In fact, in both cases, the stiffening member is positioned outside of thecontainer body 1. As a result of this choice, it has also proved appropriate to design the bottom wall of the said stiffening member with a plurality of holes, and the said stiffening member has been provided with means which allow fluid communication between said bottom wall and the external environment. The aim is to cause the collapse, upon entry of hot water under pressure inside thecontainer body 1, of thebottom wall 101 of the container body itself against the reliefs on the bottom wall of the stiffening member; then, the infusion may be discharged towards the dispensing and/or collection means via the holes formed in the bottom wall or via channels formed in the side walls.
