CROSS REFERENCE TO RELATED APPLICATIONS

This application is a National Stage of International Application No. PCT/PT2019/050023, filed Jul. 30, 2019, claiming priority to Portuguese Patent Application No. 110898, filed Aug. 1, 2018.

FIELD OF THE INVENTION

The present invention refers to the field of beverage distribution systems, in particular systems for preparation of beverages based upon single portions of precursor edible substances, such as for example espresso coffee and similar, presenting beverage discharge means to the interior of a drinking recipient along a direction substantially opposite to the gravity force.

BACKGROUND OF THE INVENTION

It is known to provide a beverage discharge along a direction contrary to the gravity force, and through the wall of a drinking recipient.

The reliable and ergonomic retention of the drinking recipient on a respective beverage discharge disposition, providing a regulation of the beverage discharge flow, suggests several problems to be solved.

In particular, in the case of aromatic beverages, such as for example espresso type coffee, this beverage discharge is a relevant process with potential impact upon the beverage quality obtained in the drinking recipient. In fact, in particular in the case of espresso type coffee, the main characteristics of the discharge flow determines several aspects such as the production of crème and retention thereof in the cup, and the temperature variation as a result of exposition to air during the discharge to the cup.

Document EP 1991094 B1 discloses a drinking recipient adapted so that can be filled from the base and presenting a sealable base wall for such purpose, whereby the beverage is injected with enough pressure to open a valve provided as flow regulation element of beverage discharge flow.

Document EP 2029470 B1 discloses a system of the type of the present invention. In particular, the drinking recipient presents a base region adapted so that can be retained on a beverage discharge disposition, whereby said disposition presents guides configured so as to cooperate with complimentary guides on the base region of drinking recipient so as to guide the displacement of the discharge injector with relation to the recipient, by means of rotation of the recipient on said formation, so that the discharge injector penetrates in the charge opening and the single-way valve of the recipient. In particular, the exterior surface on the base region of beverage recipient, presents two guide formations configured in form of “L” that develops along a direction transversal to the gravity force, whereby said guide formations operate with corresponding projections of tooth type provided on a surface of said beverage discharge disposition. From said disposition results that a glass can be placed at a first angular position and manually rotated afterwards along a given angular direction and by a given angle until a second angular position where it gets retained, and vice-versa for releasing the glass after beverage discharge.

Document EP 2120652 B1 discloses another system of the type of the present invention, whereby the base region of said drinking recipient can be retained by means of a thread on a placement disposition configured as brewing device so that can collect a capsule containing a beverage percussing edible substance, downstream of the fluid discharge and upstream of base portion of drinking recipient. Moreover, the base region of said placement disposition presents three transversal projections developing inwards that, in correspondence with three transversal projections associated with a fluid discharge disposition and developing outwards, provide the placement and retention of said placement disposition on the fluid discharge disposition by means of rotation of said placement disposition around a respective central axis, thereby providing connection in fluid communication of the upstream fluid discharge with the drinking recipient downstream.

Said placement disposition by fitting can be associated with the base region of a drinking recipient, for example a coffee cup, notably by means of a connection of thread type, and be adapted so that provides retention in removable manner on said beverage discharge support, in particular by means of placement and actuation of an element of mechanical engagement with an engagement portion on the base region of said placement disposition.

Said placement disposition by fitting presents a flow regulation disposition that provides flow passageway when the placement disposition is placed on a fluid discharge disposition, so that the flow regulation disposition is mechanically actuated by a corresponding projection in the beverage discharge support to allow flow passageway.

GENERAL DESCRIPTION OF THE INVENTION

Said system comprises at least one type of drinking recipient (1, 1′), such as for example a cup or a glass, that presents a base wall (11) comprising a passageway opening (110) and a flow regulation disposition (12), whereby said drinking recipient (1) is adapted so that can be retained on a beverage discharge disposition (2).

Said system comprises a beverage apparatus (3), for example in the form of a machine for preparing espresso coffee and similar aromatic beverages, that presents at least one brewing device (4) provided as interior or exterior part of the casing of said apparatus (3), and so that can collect a portion (5) of edible substance that is precursor of beverage, for example contained in a capsule or similar, and supplied preferentially through an introduction opening (8) disposed for example in the vicinity of said beverage discharge disposition (2).

Moreover, it is preferred when said beverage apparatus (3) includes a fluid reservoir (not represented), as well as a flow pressurization device (7) and a fluid heating device (not represented), so that can supply a flow (FS) at a temperature comprised between 60 and 100° C. and pressure between 1 and 20 bar, preferentially more than 10 bar, so as to interact with said edible substance.

Said discharge flow (BD) is then conducted to an exit of said brewing device (4) and to a beverage discharge disposition (2) arranged downstream thereof and that includes at least one beverage discharge element (21) adapted so that can retain a drinking recipient (1, 1′), preferentially by means of mechanical engagement with the base region (11) thereof.

The system includes a plurality of types of drinking recipients (1, 1′) presenting different dimensions, in particular different dimensions, for example diameter, of respective base walls (11), but adapted so as to engage in a same type of beverage discharge disposition (2), whereby at least one of said types of drinking recipients (1, 1′) is not a disposable recipient.

As represented in FIG. 2, said types of drinking recipients (1, 1′) can present a flow regulation disposition (12), for example of the type one-way valve (symbolically represented by a triangle), provided retained in an opening of passageway (110) of said base wall (11) and adapted so that only provides passageway to a pressurized flow of beverage discharge (BD) downstream, to said collection space (A), in a direction opposite the gravity force, if impinged with a flow pressure bigger than a previously defined value of flow pressure.

According to a particularly relevant aspect, said sidewall (112) of said drinking recipients (1, 1′) is devoid of exteriorly-oriented projections on the base region, so that all the recipient retention means are provided inside of a cavity formed by the edge portion of the sidewall (112) that projects beyond said base wall (111).

Taking the embodiment represented in FIGS. 3 to 6 as a reference, and according to a first inventive aspect, said drinking recipients (1, 1′) and said beverage discharge disposition (2) are adapted so that said placement position (I) is only provided in one or two previously defined angular extensions of said drinking recipients (1, 1′) with relation to said beverage discharge disposition (2).

Said drinking recipient (1, 1′) can present one or two recipient retention means (17) that develop along a respective angular extension, corresponding to a segment of perimeter in the interior of said cavity formed on the base region of said drinking recipient (1, 1′).

In particular, said recipient retention means (17) can develop outwards, with relation to the longitudinal axis (X), from a first edge wall that surrounds a flow passageway (110), and/or inwards, from a second edge wall that develops along an exterior perimeter of the base region of said drinking recipient (1, 1′).

The retention of the drinking recipient (1, 1′) is thus provided by a first engagement that acts mostly along the direction of the longitudinal axis (x), retaining the drinking recipient (1, 1′) against the force exerted by the beverage discharge flow (BD), and a second engagement of pressurized fitting type that acts substantially along the angular direction, preventing the drinking recipient (1, 1′) from vibrating or that may rotate during the injection of said beverage discharge flow (BD). Moreover, this second engagement conveys a haptic perception to the user as to the sufficient retention of the drinking recipient in a retention position (II) and, preferentially, also as to a preferential direction, of less resistance, of rotation of the drinking recipient (1, 1′) towards the retention position (II).

FIGS. 11 and 12 show another embodiment of the present invention.

In this case, at least one of said first and second parts (11, 12) presents a recipient reference (18) provided so that is perceptible by a user at least visually, preferentially also in tactile manner, and that references at least one angular position of the drinking recipient (1, 1′) that provides a placement position (I) on said beverage discharge disposition (2), in particular with relation hereto, whereby it is preferred when said recipient reference (18) is provided as at least one of: an indicia and a constructive portion associated with said drinking recipient (1, 1′).

It is herewith advantageously provided that a user can readily recognize in which position to place the drinking recipient (1, 1′) in a beverage discharge disposition (2), despite the retention means not being visible.

It is further preferred when said beverage discharge disposition (2) presents at least one placement reference (26, 26′) provided so that is perceptible by a user at least visually, preferentially also in tactile manner, whereby at least one first placement reference (26) references an angular position that provides a placement position (I) of said drinking recipient (1, 1′) on said beverage discharge disposition (2), and preferentially a second placement reference (26′) that references at least an angular position that provides a retention position (II) of said drinking recipient (1, 1′) on said beverage discharge disposition (2), whereby it is preferred when said placement reference (26, 26′) is provided as at least one of: an indicia, an information display and a constructive portion associated with said beverage discharge disposition (2).

In this particular, by means of said placement references (26, 26′) an apprehensible indication can be provided to the user that the drinking recipient (1, 1′) has been placed in the support on a first instant, and that has been then correctly retained on a second instant.

It has been further proven as advantageous, when said first and second recipient parts (11, 12) present respective parts and recipient retention means (16, 17) provided so that can be manually actuated in similar manner, including preferentially by means of a rotation movement around the longitudinal axis (X) along an extension smaller than 110°, preferentially smaller than 80°.

FIGS. 13 and 14 show a first, and 15 and 16 show a second of two preferred embodiments of the beverage discharge disposition (2) so as to provide operative retention of drinking recipients (1, 1′) of different dimension. In particular, in the case of a first embodiment, said discharge element (21) including at least part of the injection device and retention means, is provided with relation to the recipient placement support (22) so that results at least partially, preferentially completely, inside of a cavity of relatively proximal dimensions, whereas in the case of a second embodiment such does not take place, so that the recipient placement support (22) can coincide with an exterior surface of said beverage discharge disposition (2).
