Abstract
A beverage dispensing device includes a container for a liquid beverage to be dispensed, a beverage dispensing line, and a gas line. A keg connector connects the keg interior with the dispensing and gas lines by coupling the keg connector to a container closure. A storing compartment has means for receiving at least two containers. An elongated tapping column is fixed to the top plate and provided with a tapping valve element. The means for receiving at least two containers permits container storage in a dispensing position with its longitudinal axis forming a storing angle of ±30° with respect to the top plane. The keg connector has a height measured along the longitudinal axis between the container's bottom end, and the furthest point of the keg connector coupled to the closure of the connector is not more than 5% greater than the height of the container without keg connector.

[0033] For a fuller understanding of the nature of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings in which:

DETAILED DESCRIPTION OF THE INVENTION
[0042] As shown in
[0043] Typically, 50 litre kegs (8) generally made of metal are used in such conventional dispensing units. Such kegs cannot be lifted or otherwise handled easily; and they are usually rolled over the rim of their bottom base to bring them in front of the storing compartment (11) and positioned vertically. A keg connector is used to couple both gas line (6) and dispensing line (4). With the wide-spreading use of containers of smaller capacity, it is clear that the volume of the storing compartment (11) is not efficiently taken advantage of if such smaller kegs are arranged vertically like the larger 50 litre kegs. The containers used in a dispensing device according to the present invention typically have a capacity of 8 to 25 l and are generally made of polymers such as PET as discussed in the introduction. As illustrated in
[0049] The shoulder region (8s) can be in the shape of a circularly symmetric ellipsoidal cap (i.e., having an axis of revolution or, in other words, having a circular open edge), preferably a spherical cap. With blow-moulded, polymeric containers, the bottom end (8e) can also have a similarly circularly symmetric ellipsoidal cap, the shoulder ellipsoidal cap and the bottom end ellipsoidal cap sandwiching the cylindrical body portion (8b).
[0050] According to the present invention, the storing compartment is designed for storing more than one such keg in a more or less horizontal dispensing position, corresponding to a position wherein the longitudinal axis, X1, of each container forms a storing angle of ±30° (i.e., comprised between −30° and +30° with respect to the top plane, π, preferably comprised between ±10°, more preferably ±5°, most preferably substantially parallel to the plane, π.
[0051] As illustrated in
[0056]
[0057] Because of the substantial weight of the liquid beverage, the force F2=F2, 1 when the container is full is substantially larger than the force F2=F2, 0 when the container is nearly empty. Consequently, a container (81) can be stable when full, because F1±d1<F2, 1×d2, but will tilt and fall down when nearly empty because F1±d1>F2, 0×d2. Such tilting is more pronounced with polymeric containers (81) which are very lightweight compared with the usually metal keg connectors traditionally used in pubs and restaurants. To stabilize the containers when stored substantially horizontally, the left hand side member, F1×d1, of the tilting moment balance must be reduced, by reducing the value of F1 and/or d1. To this effect, it is essential for the present invention that the keg connector (1) does not extend too far beyond the level of the closure. As illustrated in
[0058] As discussed above, the container comprises: [0059] (i) a closure (10) sealing an opening of the container, adjacent to [0060] (ii) a neck region (8n) broadening into [0061] (iii) a shoulder region (8s) until reaching [0062] (iv) a substantially cylindrical body portion (8b) adjacent to [0063] (v) a bottom end (8e).
[0064] With such geometry, the tilting axis of a container is generally located at the level where the cylindrical body meets the shoulder region, as shown in
[0065] In order to further reduce the value of the distance, d1, it is preferred that the height, H2, includes at least 20 cm of the upstream portion (4u) of the dispensing line (4) and of the downstream portion (6d) of the gas line (6). This can be achieved by orienting the upstream portion (4u) of the dispensing line and the downstream portion (6d) of the gas line (6) are each independently coupled to the keg connector with an angle comprised between 45 and 135° preferably, between 80 and 100°, with respect to the longitudinal axis, X1, when the keg connector is coupled to the container. For example, the keg connectors illustrated in
[0066] In order to further decrease the value of the left hand side member, F1×d1, of the tilting moment balance, the weight of the keg connector (1) can be reduced by replacing metal, which is traditionally used in conventional keg connectors, by polymers for part or the whole of the keg connector. In a preferred embodiment, the keg connector is made of at least 60 wt. % of polymer, preferably at least 80 wt. %, more preferably at least 95 wt. % of polymer. Polymers such as polyethylene, polypropylene, polyamide, polyethylene terephthalate, polyurethane, and the like can be used pure, blended, and/or reinforced with fibres.
[0067] Referring to
[0072] Examples of keg connectors suitable for the present invention are disclosed e.g., in WO2014057099 (cf. present
[0073] The keg connectors of
[0074] Closures (10) suitable for the present invention are described e.g., in WO2009/090225, WO2009/090224, WO2009/090223, WO2012004223, the contents of which are included herein in their entirety by reference. The closure (10) generally comprises a skirt provided with coupling means for reversibly coupling to the neck region (8n) of the container by means of a thread, bayonet or snap features. The skirt defines a lower rim below which the protrusions (13p) can engage to clamp the keg connector to the closure. As discussed supra, it is, however, preferred to clamp the clamping legs below an annular flange (8f) integrally part of the container (cf.

[0079] The dispensing device of the present invention is adapted to the new evolution of smaller, lightweight containers used to dispense fermented beverages such as beer and other carbonated beverages. Handling of the containers is greatly facilitated and capacity of storage of the containers is optimized with the present invention.
