[0001] The present invention relates to an adapter device in taps for delivery of beverages
and the like, and, in particular, an adapter device that allows a pre-mix type tap
to be connected to a post-mix type of attachment.
[0002] The definitions pre-mix and post-mix are well known to those skilled in the art.
The term pre-mix identifies those beverages that reach the delivery tap already mixed
with a gas under pressure, while beverages of the post-mix type are composed of two
liquids, soda and syrup, that are mixed at the delivery stage in suitable taps.
[0003] Consequently, the taps are different. A pre-mix type tap is equipped with a connector
that receives a single fluid for delivery.
[0004] A post-mix type tap is more complex and comprises a pair of separated connectors,
one for soda or water delivery, and the other for syrup delivery, with the liquids
from the two connectors being mixed as they outlet from the tap.
[0005] The systems for delivery of the beverages, generally incorporated into dispenser
columns, are often dedicated to the delivery of a single type of beverage, e.g. only
beverages of the post-mix type, or often are predisposed to allow the delivery of
a pre-established number of post-mix beverages and a pre-established number of pre-mix
beverages.
[0006] The need is therefore felt for being able to vary the delivery taps associated with
every unit for the delivery of beverages according to demand, without having necessarily
to change an already installed dispensing unit or without having necessarily to install
additional dispensing units.
[0007] The object of the present invention is therefore to provide a fast, efficient and
limited-cost solution in order to overcome the limits of the known type of beverage
delivery units.
[0008] This object is achieved by the present invention, which relates to an adapter device
in taps for delivering beverages or the like, of the type comprising at least one
inlet port and at least one outlet port placed in mutual fluid communication with
at least one channel, characterised by comprising an inlet section in which the inlet
port is arranged and which serves for being coupled to a post-mix type attachment,
at least a first one of the two connectors of the post-mix type attachment being connectable
to the inlet port, and an outlet section, in which the outlet port is arranged, which
comprises means for connecting the outlet port in fluid communication with a pre-mix
type delivery tap.
[0009] The adapter device preferably comprises also a blind seat which serves to receive
the second of the two connectors of the post-mix attachment and to obstruct the outflow
from it.
[0010] The connection in fluid communication is preferably carried out to the syrup delivery
connector of the post-mix attachment.
[0011] The outlet port of the connector is aligned axially with the connection portion of
the pre-mix tap, thus adapting to the majority of existing taps on the market, with
interposition of a short length of connecting pipe where necessary.
[0012] The adapter device according to the invention can therefore easily be used to modify
the configuration of the taps in every dispensing unit in a particularly simple and
economic way.
[0013] Further features and advantages of the present invention will become clearer from
the description that follows, which is given by way of example and not for limiting
purpose, with reference the attached drawings, in which:
- Figure 1 is a cross-section of an adapter device according to the present invention;
- Figure 2 is a partial cross-section which shows a pre-mix type tap mounted on a post-mix
attachment by means of an adapter device according to the invention;
- Figure 3 is a partial cross-section which shows another pre-mix type tap mounted on
a post-mix attachment by means of an adapter device according to the invention; and
- Figures 4A and 4B are cross-sections of some auxiliary members of the adapter device
according to the present invention.
[0014] Figure 1 shows an adapter device 10 that is preferably made in plastic material suitable
to be in contact with foodstuffs, by means of moulding.
[0015] The device comprises in particular an inlet section 20 comprising an inlet port 21
destined to receive the connector 1 (Figures 2 and 3) of an attachment of the post-mix
type, as well as an outlet section 30 comprising an outlet port 31. The inlet port
21 is placed in fluid communication with the outlet port 31 by means of a channel
40.
[0016] In the inlet section 20 of the device 10 there is a blind seat 22 which serves to
receive the connector 2 (Figures 2 and 3) of the post-mix attachment in order to obstruct
the outlet flow from the same.
[0017] With reference to the views of Figures 2 and 3, connector 1 of the post-mix attachment
effectively used is preferably that of the syrup, while obstructed connector 2 is
that of the soda. The delivery port of the syrup is therefore used in order to carry
the pre-mix beverage already prepared to a delivery tap 200 (Figure 2) or the delivery
tap 300 (Figure 3).
[0018] Both delivery taps 200 and 300 in Figures 2 and 3 are some examples of taps of the
pre-mix type. Tap 200 in Figure 2 is as an example of a model destined mostly for
the delivery of beer, while tap 300 in Figure 3 is an example of a model used for
other beverages of pre-mix type.
[0019] The connection of a tap of the pre-mix type to the adapter device can be carried
out directly in an internally threaded seat 35 of the outlet section 30.
[0020] Outlet port 31 is axially aligned with the entrance portion of the pre-mix type tap
destined to being connected to the adapter device. That allows in particular the use
of the most varied models of the pre-mix type taps currently available on the market
without creating problems for the flow of the beverage being delivered.
[0021] In order to allow the connection of pre-mix taps of varied type or in order to increase
the distance of the tap from the delivery unit to which it is connected, short pipe
fittings like those shown in Figures 4A and 4B can be provided.
[0022] Pipe fitting 60 shown in Figure 4 serves as an example of the adaptation of threads
of different diameters between adapter device 10 and tap 200 of Figure 2, while pipe
fitting 70 of Figure 4B is an example of a pipe used as an extension for tap 300 of
Figure 3.
[0023] As is very clear from the above, the adapter device according to the invention is
very simple and economical to produce as well as to install.
[0024] That advantageously allows to considerably increase the flexibility of the system
already installed and originally dedicated mostly or exclusively to delivery of post-mix
beverages, with great advantage of the habitual users of the delivery units of this
type.
