Abstract
Description
- The present invention relates to a capsule for preparing beverages as defined in the preamble of
claim 1. - In particular, according to the present invention, the capsule is suitable for use in machines that are conveniently designed to prepare coffee, namely espresso, as well as tea, infusions and else.
- The use of beverage preparation capsules is known in the art. These capsules are filled with an ingredient for beverage preparation, e.g. coffee grounds or tea. In operation, the capsule is introduced into a special machine, which breaks its seal. A fluid, typically water, is forced to flow under pressure into the capsule. The ingredient or a part thereof are soluble in the fluid, and will be dispensed from the capsule as a beverage, for example coffee or tea.
- One example of a beverage preparation capsule is disclosed in
EP 2 892 824 B1WO 2013/167434 A1 - This patent discloses a capsule equipped with a pressure-sensitive membrane, which comprises at least one weakened or precut line defining a non-reclosable opening. This opening has a width of not more than 1 mm once pressure returns to atmospheric pressure. According to the teachings of the patent, this feature provides an anti-dripping effect due to the capillarity of the opening.
- A further example of a beverage preparation capsule is disclosed in
EP 1472156 . - This patent discloses a capsule having with a pressure-sensitive membrane located proximate to the bottom of the capsule. In addition, opening means are provided between the bottom of the capsule and the membrane, which are embodied as tips that face the membrane. According to the teachings of patent '156, the membrane is pushed by the pressure of the fluid that flows into the capsule against the opening means, and is torn thereby, to allow the mixture to flow out of it. More in detail, the membrane is configured to move relative to the opening means to ensure that the membrane will be torn on said opening means.
- One drawback of these types of capsules is that they do not always ensure optimal dispensing of the beverage. Pressure variations in the extraction fluid caused by irregular calibration or loss of the original calibration of the pump of the apparatus may cause a less than optimal dispensing of the beverage. This may affect the quality of the beverage, particularly coffee.
- Therefore, the technical purpose of the present invention is to provide a beverage preparation capsule that can obviate the above-mentioned prior art drawbacks.
- In particular, the object of the present invention is to provide a capsule for beverage preparation that can optimize dispensing as well as the quality of the beverage so prepared.
- The aforementioned technical purpose and objects are substantially fulfilled by a beverage preparation capsule that comprises the technical features as disclosed in one or more of the accompanying claims.
- In particular, one embodiment of a capsule for beverage preparation of the present invention comprises a capsule body. This capsule body comprises a side wall and a bottom wall connected to the side wall. The bottom wall is configured to be permeable to a liquid. The capsule body has an opening opposite to the bottom wall. This opening is designed to be sealed by a closure element.
- A cover element is provided at the bottom wall. The cover element is rupturable, so that it may be torn open by a predetermined pressure of a fluid introduced into the capsule body.
- The capsule comprises a spacer element between the bottom wall and the cover element. Such spacer element comprises a plurality of projections that jut out of the bottom wall and an edge that defines a perimeter. The cover element is stably attached to the spacer element at adhesion zones, via attachment means. This cover element is torn by the pressure exerted by the fluid introduced into the capsule body to thereby define one or more slits for the passage of the fluid. The slit has a width of more than 1 mm.
- The device solves the technical problem, because the wider slit facilitates the flow of the fluid through the capsule and, as a result, allows the beverage to be dispensed more uniformly without undesired dripping. The beverage so obtained will always have an optimal quality, even when minor pressure variations occur.
- Further features and advantages of the present invention will result more clearly from the illustrative, non-limiting description of a preferred, non-exclusive embodiment of a beverage preparation capsule as shown in the annexed drawings, in which:

- Referring to the annexed figures,
numeral 1 designates a beverage preparation capsule according to the present invention. - The
capsule 1 comprises acapsule body 2. Thiscapsule body 2 has a substantially frustoconical shape. - The
capsule body 2 comprises aside wall 3. - The
capsule body 2 further comprises abottom wall 4, which is connected to theside wall 3. - As shown for example in
figure 2 , thebottom wall 4 has a concavity that faces the interior of thecapsule body 2. - In alternative embodiments, not shown, the
bottom wall 4 may have a concavity that faces the exterior of thecapsule body 2 or may be substantially flat. - More in detail, as shown in
Figure 2 , thebottom wall 4 has a substantially flatperipheral zone 4a and a concavecentral zone 4b. - It shall be noted that the
bottom wall 4 is designed to permeable to a liquid, which means that it has at least onehole 5. - Furthermore, the
capsule body 2 has an opening 6 opposite to thebottom wall 4. This opening 6 is designed to be able to be sealed by aclosure element 16. Thisclosure element 16 may be, for example, a film (or a membrane or a lid), which is designed to be punctured by a beverage-making machine. - A
flange 14 is provided at theopening 6. - This
flange 14 projects out of theside wall 3 toward the exterior of thecapsule body 2. - The
aforementioned closure element 16 of thecapsule 1 is generally fixed to theflange 14, particularly by heat sealing. - The
capsule 1 further comprises acover element 7, located at thebottom wall 4. - This
cover element 7 is advantageously impermeable to both liquids and gases, to thereby protect the organoleptic qualities of the ingredient that will fill thecapsule 2. - The
cover element 7 is rupturable, so that it may be torn open by a predetermined pressure of a fluid introduced into thecapsule body 2. - This predetermined pressure has a value indicatively ranging from 3 bar to 15 bar, preferably of 9 bar.
- In particular, the
cover element 7 has one or moreweakened lines 7a that are defined, for example, by a pre-cut in a pre-cut formed by laser perforation. - Also referring to
Figure 3 , thecapsule 1 comprises aspacer element 8. -
Such spacer element 8 is placed between thebottom wall 4 of thecapsule body 3 and thecover element 7. - The
spacer element 8 particularly contacts thebottom wall 4 of thecapsule 3, namely theperipheral zone 4a. - The
spacer element 8 also contacts thecover element 7. For this purpose, thespacer element 8 has a plurality ofcontact zones 9 that face thecover element 7, whereat thecover element 7 contacts thespacer element 8. - In particular, proximate to the
contact zones 9, thecapsule 1 comprises attachment means 18 that stably attach thecover element 7 to thespacer element 8. By this arrangement, the attachment means 18 rigidly join thecover element 7 and thespacer element 8 together to prevent any relative movement between thecover element 7 and thespacer element 8. - In other words, the
cover element 7 is stationary relative to thespacer element 8 and therefore cannot move relative to thespacer element 8 even when the pressurized fluid flows into the capsule body. - More in detail, also referring to
Figure 2a , these attachment means 18 comprise a layer of adhesive material configured to rigidly join thecover element 7 and thespacer element 8 together. - The attachment means 18 may be biodegradable adhesives, heat sealing or other types known to the skilled person.
- The
cover element 7 also contacts thecapsule body 4 at thezones 12. The use of attachment means is not provided in these zones. - As shown in
Figure 4 , thespacer element 8 has the shape of a disk and, in particular, has a diameter that is substantially the same as the inside diameter of thecapsule body 2 in the vicinity of thebottom wall 4. - More in detail, the
spacer element 8 comprises abase wall 11. Thisbase wall 11 particularly has a disc shape and has a center axis "A". - The
spacer element 8 comprises anedge 12a and a plurality ofprojections 9a. - In particular, the
edge 12a defines an outside perimeter of thebase wall 11. Theedge 12a extends away from thebase wall 11 of thespacer element 8 and from thebottom wall 4 of thecapsule body 2. - More in detail, the
base wall 11 has acentral zone 11b at the center axis "A". Anouter zone 11c is defined at theedge 12a. Anintermediate zone 11d is located between thecentral zone 11b and theouter zone 11c - It shall be noted that the
outer zone 11c and theintermediate zone 11d have a substantially annular shape. Thecentral zone 11b has a substantially circular shape. Furthermore, as shown inFigure 5 , thecentral zone 11b has a concavity that faces toward thecover element 7. - The
outer zone 11c has a plurality ofholes 13 for the passage of the fluid, as theintermediate zone 11d acts as a sort of fluid-supplying channel. - These
holes 11 are at equal distances from the center axis "A". Furthermore, theholes 13 are equally angularly spaced relative to the center axis X'-X'. - In particular, the plurality of
projections 9a juts out of thebase wall 11 of thespacer element 8 toward the interior of thecapsule 1. In one aspect, the projections substantially extend parallel to theedge 12a. - In particular, the
aforementioned projections 9a are formed at theintermediate zone 11d. The number ofprojections 9a ranges from four to eight, and is particularly six. - More in detail, it shall be noted that the
projections 9a have a height that ranges from 1.6 to 2 mm, and is preferably 1.8 mm. The term "height" is intended to designate the extent of theadhesion zones 9 with respect to thebase wall 11 of thespacer element 8. - The
edge 12a also has a height that ranges from 1.6 to 2 mm, particularly of 1.8 mm. - Thus the
projections 9a define portions of a plane at which thecover element 7 is rigidly joined to theintermediate element 8 via the attachment means 18. - Each of the
projections 9a has the shape of a circular sector. - In particular, each projection has an angular width relative to the center axis "A" that ranges from 40° to 60°, and is preferably 50°.
- Each
protrusion 9a is separated from anotherprotrusion 9a adjacent thereto by an angular distance ranging from 5° to 15°, and particularly of 10°. - While the beverage is being dispensed, the
cover element 7 is torn at the zone of the weakenedline 7a by the pressure of the fluid introduced into thecapsule 1, and such tearing defines at least one slit 10. - In particular, when pressurized fluid is introduced into the
capsule 1 thecover element 7 remains stationary in its position, as it is attached to thespacer element 8 via the attachment means 18, proximate to theprojections 9a, thus facilitating tearing at the weakenedline 7a and defining two or more flaps 15. - In other words, since the
cover element 7 is retained proximate to theprojections 9a make, the pressure of the working fluid introduced into thecapsule 1 is concentrated at the weakenedline 7a and facilitates tearing of thecover element 7. - Since the
cover element 7 mainly rests on theprojections 9a and theedge 12a of thespacer element 8, theflaps 15 of thecover element 7 are pushed againstsuch projections 9a, and are bent at thecentral zone 11b of thebase wall 11 thereby further opening out the slit 10. - Advantageously the
adhesion zones 9 between thecover element 7 and thespacer element 8 facilitate tearing of thecover element 7. - Advantageously the
adhesion zones 9 ensure constant tension of thecover element 7. - It shall be noted that the slit 10 created with the introduction of the extraction fluid, during and at the end of the dispensing operation, has a width of more than 1 mm to facilitate the outflow of the fluid in the
capsule 1, without causing undesired dripping. -
Figure 7 shows a typical slit 10 created with the use of thecapsule 1. Thus, the width of the slit 10 is found to range from 1.4 to 1.6 mm after dispensing of the beverage. More in detail, the width of the slit 10 was measured by assessing the distance from the twoflaps 15. In particular, eachflap 15 has amain edge Figure 7 , the width of the slit 10 is measured at multiple points by (ideally) connecting the twoedges flaps 15 with lines parallel to each other and perpendicular to the line that follows thestraighter edge 15a of theflap 15. In other words, the distances are measured between the twoedges flaps 15 at multiple points, to assess an average of the actual width of the slit 10. - Those skilled in the art will obviously appreciate that a number of changes and variants as described above may be made to fulfill particular requirements, without departure from the scope of the invention, as defined in the following claims.
