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 observe, in both cases said support (2) of single portions presents holes (25, 26) in the dividing region between successive single dose portions (21). In particular, according to a first inventive aspect, there are provided at least two holes of different form (25, 26) and/or dimensions (25, 25′) (drawing on the left-side), so that can be individually recognized as a result of the variation of a beam of light projected upon them by information apprehension means (7) provided in the machine (10), as shall be described in greater detail further below.
In this respect, at least one of said holes (26) can present a geometric form that varies for example in the case of a given type of beverage, such as coffee, tea, or other edible substance. Moreover, as depicted in the embodiment represented on the left side, said holes (25, 26) present a decreasing dimension along the support extension (E), so that this provides an indication on the part thereof that has already been used and, therefore, the number of single dose portions (21) still remaining.
According to a preferred embodiment, said holes (25, 26) are provided in a single cross alignment in dividing regions between successive single dose portions (21), preferentially at least in the dividing region between a first and a second single dose portion (21). According to another preferred embodiment, said holes (25, 26) are provided in only part of the dividing regions between successive single dose portions (21) along the support extension (E) of said support (2) of single portions.
Alternatively, according to said inventive aspect, the support (2) of single portions presents at least three holes (25, 25′, 26) of different or similar form and/or dimension (drawing on the right side). In this case, in a first region there are provide two holes (25) of similar form and characteristic dimension and one hole (25′) of different dimension, in this case diameter. This variation can serve to identify the total number of single dose portions (21) available in that support (2) of single portions and, therefore, in the respective supply cartridge (1).
According to a preferred embodiment, at least one of said holes (26) can therefore present a different form in at least one upstream disposition of holes (25, 26), so as to convey other type of relevant information to a respective beverage preparation process.
In a first embodiment (drawing on the left), the support (2) of single portions presents a sequence of three holes (25) at given reference positions along a respective extension (E), whereby said sequence can vary for example so that one of said holes (25) is absent in at least one dividing region between successive single dose portions (21).
In the case of a second embodiment (drawing on the right side), there is provided a variation of the number and of the dimension of some of said holes (25). As it shall be readily understood, it is herewith provided a binary code whereby a given information parameter is associated with a given set or sequence of holes (25).
In dimensional terms, according to a preferred embodiment, said support (2) of single portions presents a plurality of single does 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 to 120 single dose portions (21), preferentially between 20 to 80 single dose portions along a respective extension (E).
In this case, both supports (2) of single portions comprise five reference positions presenting holes (25, 25′) in dividing regions between successive single dose portions (21), whereby there is provided a variation of the number and relative position of the holes (25′) of different dimension in each one of said regions (considering the sequence of holes (25, 25′) from the left to the right).
In a first case (drawing on the left-side), the holes (25) that present a smaller characteristic dimension are provided in a second and fourth positions, whereas in a second case (drawing on the right-side) the holes (26) are provided in a first, third and fifth position. As in the previous case, also in this case the supports (2) of single portions can be used for different types of beverages.
Moreover, according to another preferred embodiment, at least some of said holes (25) are adapted so as to engage with corresponding engaging elements, in particular with traction pins (not represented) provided in the actuation device (5), so as to provide a more efficient transfer of the traction force to said support (2) of single portions. Considering the width of the support (2) of single portions, this solutions advantageously increases the efficiency and reliability of transfer of movement to the support (2) of single portions, so that it is preferred when there are provided at least two holes (25) for engagement and the remanding for representation of information in the form of a binary code.
According to a preferred embodiment, a first type of supply cartridge (1) can be completely collected inside of said collection disposition (3) and temporarily closed in the front and top faces thereof. In particular, said collection disposition (3) presents front (32) and top parts (33) adapted so that can be fixated in removable manner or so that can be rotated around an axis, thereby facilitating the placement of at least one type of cartridge, preferentially of at least two types of supply cartridge (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 towards the front zone and adapted so that 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 supply cartridge (1) 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 at a distal region of said collection disposition (3) relative to the front part of the machine (10). Said fixation means (31) are provided as elastic elements adapted so that they are elastically deformed at the time of placing of a supply cartridge (1), 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 direction of depth (D) of said machine (10) for preparing beverages.
In particular, the machine (10) presents information apprehension means (7) adapted so that they can recognize the number and/or dimension and/or form of the holes (25, 25′) provided in said support (2) of single portions, preferentially disposed in the region between at least part of successive single dose portions (21), whereby said information apprehension means (7) are provided in functional connection with a control device (8) of said machine (10).
According to a preferred embodiment, said information apprehension means (7) are disposed in a region downstream of the exit of said supply cartridge (1), preferentially between said collection disposition (3) and an actuation device (5) and comprise lighting means (71) adapted so as to light up said support (2) of single portions and image collection means (72) adapted so as to recognize at least the number of holes (25), preferentially also the form and/or dimension of the holes (25) in each respective position.
According to another preferred embodiment, said lighting means (71) are provided underneath or above of the passage region of said support (2) of single portions and said image collection means (72) are provided in direct opposition to said lighting means (71), on the other side of said passage region.
A process of preparation of beverages based upon said machine (10) thus includes the steps of actuating said information apprehension means (7), provided downstream of the exit of said supply cartridge (1), so as to collect information provided in the form of a binary code, preferentially in the dividing region between successive single dose portions (21), and communicating at least one respective information parameter to a control device (8) of said machine (10).
According to a preferred embodiment, said step of actuation of the information apprehension means (7) is initialized after each actuation of said actuation device (5), so as to apprehend the information that is coded in the holes (25, 26) provided between successive single dose portions (21).
