DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0030] 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).

[0031] FIG. 1 represents views of a support (2) of single portions according to the prior art, whereby said single dose portions (21) present a length (C) along the direction of said extension (E), and a width (L) along a cross direction.

[0032] FIG. 2 represents a machine (10) for preparing beverages according to the prior art, adapted so as to use a supply cartridge (1) that comprises a support (2) of single portions of the type represented in FIG. 1. As one can observe, said machine (10) presents at least one collection disposition (3) adapted to fixate said supply cartridge (1), at least one extraction device (4) adapted so that can collect said single dose portion (21) inside thereof, and at least one actuation device (5) disposed downstream of said supply cartridge (1) and upstream of said extraction device (4) and provided so that can move said support (2) of single doses by means of rotation and thereby supply respective single dose portions (21) successively to said extraction device (4).

[0033] In particular, as one can better observe in detail P01 of FIG. 2, said actuation device (5) is adapted so that can rotate and that way exert a traction force upon a downstream edge of said support (2) of single portions, thereby moving the furthest downstream single dose portion (21) from a substantially horizontal displacement direction to a substantially vertical displacement direction, to a position where it is separated from the remanding support (2) of single portions and falls under the action of the gravity force inside of said extraction device (4).

[0034] FIG. 3 represents a first embodiment of a supply cartridge (1) according to the present invention. In particular, according to a preferred embodiment, said supply cartridge (1) comprises a package casing (11) that presents a substantially parallelepiped form presenting a height (H) and a depth (D), and adapted to collect a support (2) of single portions inside thereof, as well as presenting a weakening line provided in a exit corner (12) and adapted so that can be manually ruptured.

[0035] As one can better observe in FIG. 4, in the case of a first type of supply cartridge (1), said support (2) of single portion is disposed in zigzag so that its extension (E) is collected along the length (D) of the package casing (11), so that a first downstream edge results in the proximity of an exit opening (12).

[0036] FIG. 5 represents a first set of embodiments of a support (2) of single portions contained in a supply cartridge (1) according to the present invention.

[0037] 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.

[0038] 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 belowthere 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.

[0039] 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.

[0040] 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).

[0041] FIG. 6 represents a second set of embodiments of support (2) single portions contained in a supply cartridge (1) according to the present invention.

[0042] 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).

[0043] FIG. 7 represents a third set of embodiments of support (2) of single portions contained in a supply cartridge (1) according to the present invention.

[0044] 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.

[0045] 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.

[0046] FIG. 8 represents a fourth set of embodiments of a support (2) contained in a supply cartridge (1) according to the present invention. As one can observe, said support (2) of single portions in this case presents a plurality of holes (25, 26), in particular at least four holes (25, 26) disposed along the cross direction and presenting at least two different dimensions. This configuration advantageously enables a better transfer of movement from an actuation device (5) provided in a machine (10) for preparing beverages.

[0047] FIG. 9 represents a first embodiment of a machine (10) for preparing beverages adapted for using a supply cartridge (1) of the type of the present invention. In particular, the machine (10) presents a collection disposition (3) configured with a form that substantially corresponds to the form of the base zone of said types of supply cartridges (1, 1), in particular to respective width (W) and depth (D). In this case, said collection disposition (3) is configured in form a substantially parallelepiped box.

[0048] 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).

[0049] 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.

[0050] 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.

[0051] FIG. 10 represents a second embodiment of the collection disposition (3).

[0052] 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.

[0053] FIG. 11 represents the same embodiment of the collection disposition (3) as represented in FIG. 10, but in this case with a supply cartridge (1) of a different type, in particular a supply cartridge (1) presenting similar width (W) and depth (D) dimensions and a different height (H).

[0054] 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).

[0055] FIG. 12 represents a detail view of the actuation device (5) provided in a machine (10) for preparing beverages according to the present invention.

[0056] 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.

[0057] 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.
