Said document discloses a solution for the problem of the traction of the strip of multiple portions that is based upon providing a plurality of holes disposed along the side edges of the strip and adapted to be engaged by corresponding engagement saliences provided in an actuation mechanism. This solution presents several constrains, including in terms of greater construction complexity of said machine.
Document WO 2013/169134 A2 filed by the applicant of the present invention, discloses a machine for preparing beverages of the same type and adapted for processing a conduction support that provides a substantially hermetic envelope to a plurality of single doses. However, said document also does not disclose a solution that guarantees the transfer of movement by means of traction between the surfaces of the actuation element and the last single doses disposed furthest upstream in the support of single portions.
None of the documents in prior art disclose a solution for the efficient and reliable displacement of the end part of said support of single portions out of the respective packaging.
Moreover, none of the documents disclose a solution for fixating said package in simple manner in ergonomic terms and in reliable manner in operational terms, in a respective beverage preparation machine, so that the latter resists to the traction force exerted upon said support of single portions.
The objective of the present invention is to provide a supply cartridge comprising a package casing adapted to house a support of single portions provided in a flexible and elongated support, of the strip-type or similar, and adapted so that provides an efficient and reliable displacement of respective support of single portions out of said package casing, in particular so that the furthest upstream part of said support of single portions can be removed in efficient and reliable manner from the inside of said package casing when driven from outside thereof.
Said supply cartridge is preferentially adapted for use in a machine for preparing beverages, such as for example of the espresso type coffee, tea and similar, notably by means of extraction of aromatic substances packaged in said single dose portions.
This objective is solved according to the present invention by means of a supply cartridge according to claim 1.
Another objective of the present invention is to provide a machine for preparing beverages adapted for using a cartridge comprising a support of single portions in a strip form presenting a plurality of single portions, and that provides simple and reliable means for fixating of said cartridge, so as to contribute to an efficient movement of traction of said support of single portions out of said cartridge.
This objective is solved according to the present invention by means of a machine for preparing beverages according to claim 9.
Another objective of the present invention is to provide a process for preparing beverages by means of a machine for preparing beverages adapted for using a cartridge comprising a support of single portions, and that provides a more ergonomic and reliable of using said cartridge.
This objective is solved according to the present invention by means of a process according to claim 14.
The invention shall now be explained in greater detail based upon preferred embodiments thereof and the Figures attached.
The Figures show, in simplified schematic representations:
As referred above, there are known several solutions in the prior art of supply cartridges (1) adapted for use in a machine (10) for preparing beverages and collecting a strip-like, or similar, support (2) of single portions inside thereof, and presenting a plurality of single dose portions (22) provided successively along a respective extension (E).
In particular, as one can better observe in detail P01 of
As one can better observe in
According to a first inventive aspect, said support (2) of single portions presents a second upstream edge (23) provided without single dose portions (21) along an extension that corresponds to at least one length (C)—drawing on the left-side —, preferentially at least two times the length (C) —drawing on the right-side.
This way, when a last single dose portion (21) presenting a length (C) and disposed in said upstream edge (23), arrives to an actuation device (4)—provided for example as detailed further below—there is still an upstream portion of material of said support (2) of single portions, notably in an extension corresponding to at least one length (C), that provides a counterweight and that way improves the transfer of movement from said actuation device (4) to the support (2) of single portions.
According to a preferred embodiment, said second edge (23) is provided in the same format and material as the remanding support (2) of single portions. Only one single dose portion (21) is not provided, and therefore also its respective weight.
In dimensional terms, according to a preferred embodiment, said support (2) of single portions presents a plurality of single dose portions (21) with a length (C) between 40 and 70 mm, preferentially between 50 and 60 mm. Moreover, said support (2) of single portions presents between 10 and 120 single dose portions (21), preferentially between 20 and 80 single dose portions along the respective extension (E).
As one can observe, the support (2) of single portions further presents an extension of length (C) without single dose portions (21) in the respective upstream edge (23), whereby in this case this extension represents a structural reinforcement part (24) that presents a bigger linear density than the remanding support (2) of single portions and that develops along at least part of said length (C).
As one can observe, said support (2) of single portions in this case presents holes (25) in the dividing region between successive single dose portions (21), whereby said holes (25) are adapted so as to engage with corresponding engagement elements, in particular with traction pins (51) provided in the actuation device (5)—as it shall be presented in greater detail further below —, so as to provide a more efficient transfer of the traction force to said support (2) of single portions.
According to a preferred embodiment, said support (2) of single portions presents a plurality of holes (25) uniformly distributed along at least the central region of the dividing regions between successive single dose portions (21). Given the width of the support (2) of single portions, a greater number of holes (25) thus advantageously increases the efficiency and reliability of the transfer of movement to the support (2) of single portions, so that it is preferred when there are provided at least three holes (25) for engagement.
According to a preferred embodiment, a first type of supply cartridge (1) can be completely housed inside of said collection disposition (3) and temporarily closed in its front and top faces. In particular, said collection disposition (3) presents front (32) and top parts (33) adapted so that can be fixated in removable manner, or can be rotated around an axis, thereby facilitating the introduction of at least one type of cartridge, preferentially of at least two types of supply cartridges (1, 1′).
As one can also observe, said supply cartridge (1) further presents an information device (6), provided for example in the form of a RFID or similar, and disposed in the front face thereof, so that said information device (6) can be read by a device adapted correspondingly and disposed in said front part.
Moreover, according to another inventive aspect, said collection disposition (3) presents fixation means (31) disposed inside and adapted so that exert an elastic pressure upon at least part of the side faces of said supply cartridges (1, 1′). In the case of the represented embodiment, said fixation means (31) are provided in a U-like form with the opening oriented to the front zone and adapted so that they exert an elastic pressure upon the side faces of the supply cartridge (1). This type of fixation advantageously provides a rapid placement of the supply cartridge (1) in position, without requiring a particular intervention by a user. Moreover, this type of solution provides a sufficient fixation of the supply cartridge (1) relative to the traction force exerted in the front zone of the respective package casing (11) upon a support (2) of single portions, so that the movement of the latter results more efficient and reliable.
According to this preferred embodiment, said fixation means (31) are provided as at least one pair of fixation means (31) disposed in opposition, at least one distal region of said collection disposition (3) relative to the front part of the machine (10). Said fixation means (31) are provided as elastic means adapted so that can be elastically deformed when the supply cartridge (1) in placed in position, thereby exerting an elastic pressure force upon the side faces of said supply cartridge (1). According to a preferred embodiment, said fixation means (31) present an extension of at least 1 cm, preferentially at least 2 cm, along the depth direction (D) of said machine (10) for preparing beverages.
As one can observe, according to a preferred embodiment, said fixation means (31) are provided so that can be rotated on a respective edge, between a substantially horizontal orientation and a substantially vertical orientation and vice-versa, so as to better adjust to different types of supply cartridge (1, 1′) presenting different heights (H).
As represented, said actuation device (5) is provided as a driving wheel element disposed in a horizontal axis so that can rotate around thereof and thus transfer a force of traction to the support (2) of single portions, so as to move it out of the package casing (11) upstream and in the direction of the extraction device (4) downstream. According to a preferred embodiment, said actuation device (5) presents traction pins (51) in the respective perimeter surface adapted so that can engage in corresponding holes (25) provided in the region between successive single dose portions (21), as presented above.
According to a preferred embodiment, there are provided at least four traction pins (51) preferentially presenting at least two different dimensions, so that the taller and thinner initially guide the side alignment of the support (2) of single portions and the shorter and thicker then exert a particular transfer of traction force to said support (2) of single portions along the displacement direction thereof.
