Description
~ ~3 BAÇ~ÇRQ~D QF ~E I~ IQ~
The present invention relates to a device for manually inserting and removing interchangeab~e flow-rate control orifice discs into or from a syrup supply tube of a post-mix beverage dispenser.
~` 5 As disclosed in U.S. Patent 4,306r667 to Sedam, et al., issued December 22, 1981, it is desirable to utilize interchangeable flow-rate control orifice discs of selected orifice sizes in the syrup supply tubes of post-mix beverage dispensers. The orifice sizes are selected in relation to the brix of the syrup or flavor concentrate and the relative flow rate of the water (still or carbonated) with which the syrup is to be mixed to form the post-mix beverage.
' `~
The use of interchangeable orifice discs in syrup supply tubes is also disclosed in U~S. Patent 4,270,673 to Rodth.
Heretofore, when the orifice discs were to be located within the syrup tubes near the output end of the tube in the mixing chamber region of the dispensing valve assembly, it was common practice to use stainless steel Ziscs with slightly beveled edges to preclude damage to the syrup tubes at least during the insertion process... These discs were then press fit into the syrup tubes by a special tool and then removed from the tubes by a hook-shaped portion of that tool. Because the discs are very thin and the syrup tube walls are plastic, da~age to the tube walls could result during removal thereof, and in most instances the disc would be destroyed, precluding reuse thereof.
This problem is avoided to a certain extent by the invention described in the aforementioned U.S.
Patent 4,270,673 to Rodth which discloses a cylindrical plastic adaptor 98 with interchangeable orifice discs lO0 seated on an inside shoulder thereof. This adaptor fits onto the outside end of syrup tube 82, the orifice discs lO0 seating ~ .
,' .,.~. i against the tube end. Therefore, with the adaptor of Rodth it is not necessary to insert the orifice discs into the tube or to remove them therefrom.
However) the adaptor of Rodth, mounted on the outside of the syrup tube, takes up space in the valve assembly and may interfere with surrounding parts, making it difficult to retrofit the adaptor to valve assemblies of various manufacturers.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring in detail to Figure 1, there is illustrated in diagrammatic form the combination of a gravity flow syrup container 10; a valving assembly including a socket 16 for receiving the discharge end 14 of the container 10, a mixing chamber 22, and a dispensing nozzle 24; and an orifice disc adaptor 30 of the present invention inserted within a syrup supply tube ST which extends into the interior of the mixing chambers 22. The generic combination of Figure 2, with the exception of the adaptor 30, is illustrated in the aforementioned U.S. Patent 4,306,667 to Sedam, et al.
The valve assembly, including the socket, mixing chamber, nozzle and syrup tube, is best illustrated in lS the cross-sectional view of Figure 13B thereof and the gravity ~low syrup container is illustrated in Figure 1 ; thereof.
In the illustration of Figure 1 of the present invention, the gravity-flow syrup container 10 is of the type illustrated in copending Canadian Patent Application Serial No. 484,627, filed June 20, 1985, and assigned to the same assignee as the present invention. Container 10 is provided with a flow rate control tube 12 integrally molded with the sidewalls of the container, having an openable end 12A with a removable cap thereon~ When the cap is removed, atmospheric pressure is communicated through open end 12A, and tube 1~ to a point 12B
inside of the container 10 just above the neck portion thereof. That is, tube 12 opens into container 10 at point 12B to provide atmospheric pressure to the liquid in the container at that point. Point 12B is positioned at a predeterminecl distance X above the bottom of syrup tube ST, and a distance Y above any orifice disc 40 which is inserted into the syrup tube ST. It is important that the orifice disc 40 always be positioned at a distance Y from point 12B so that the liquid pressure head is a constant for determining the proper orifice sizes for the brix of syrup being dispensed. Accurate positioning of the orifice disc 40 is provided by the bottom flange 36 of the cylindrical adaptor 30, to be described in more detail hereinafter ~7ith reference to Figures 2 and 3.
As further illustrated in Figure 1, and as ~ further described in the Sedam Patent 4,306,667, - the valve assembly further includes appropriate syrup valves SP and carbonated water valve CP.
These valves are simultaneously actuated to provide syrup and carbonated water to the mixing chamber 22, the syrup flowing from the discharge opening 14 of container 10 through syrup valve SP, syrup tube ST, and any orifice disc 40 disposed therein.
10Referring to Figures 2 and 3, which illustrate ; the adaptor 30 ~ , it can be seen that the adaptor 30 has a main cylindrical body portion 32 with distal ends 32A and 32B. The diameter of body portion 32 is slightly greater than the inslde diameter of syrup tube ST, providing a force fit therein. End 32A is counterbored in the provision of an annular shoulder 34 for supporting an orifice disc 40 of stainless steel or the like with a central aperture 40A of a selected size related to the brix value of syrup being dispensed and the .~
:
~' s~
flow rate of carbonated water with which it is to be mixed. End 32B is provided with a flange 36, which acts as a stop when cylindrical body 32 is fully inserted within the end of syrup tube ST of ; 5 Figure l. Thus, flange 36 acts as a stop for accurately positioning the orifice disc 40 at a distance Y below the atmospheric pressure head within container lO.
Adaptor 30 is fabricated from plastic and is not only used for inserting an orifice disc 40 into syrup tube ST, but for positioning the orifice disc 40 therein during a dispensing operation. In order to facilitate easy removal of orifice disc 40 and adaptor 30 from within the syrup tube ST, there is provided a pull-tab 38 which is ring-shaped with a central aperture to facilitate the insertion or gripping by an operator's fingers to readily remove the adaptor 30 from the syrup tube~ In a preferred embodiment, pull-tab 30 is integrally molded with adaptor 30 as an extension of flange 36, and substantially coplanar therewith. Therefore, when adaptor 30 is fully inserted within the syrup tube ~ ST, ring-shaped pull-tab 38 lies in a position ;~ which is coplanar with flange 36 and does not ,~ 9 . ~-' .
3~
interfere with any other surrounding parts of the valve assembly. When it is desired to remove adaptor 30 from the syrup tube ST, ring-shaped pull-tab 38 is grasped by the fingers of an operator and flexed as the entire adaptor 30 is pulled out of the syrup tube in a direction longitudinally of its central axis.
Use of the orifice disc insertion and removal device of the present invention may be more readily understood by the following example. Let us assume that the syrup container 10 contains Coca-Cola ~3 ' syrup (a registered trademark of The Coca-Cola Cornpany) having a brix of 10.8 + .4~. An operator would then test the carbonated water (soda) flow rate in the absence of syrup flow out of nozzle 24.
The operator would then use the following chart to determine the proper orifice size of an orifice disc 40 to be utilized with the soda flow rate measured over a period of ten seconds.

The operator would then select a disc 40 of this orifice size, place it in end 32A of adaptor 30 so that it is snuggly seated on shoulder 3~, and insert the adaptor 30 into the syrup tube ST. The dispenser would then be ready , .~.
., :, ~ -to dispense a Coca-Cola beverage containing a proper mi~ture of Coca-Cola syrup and carbonated water.
If it is desired at some subsequent time to adjust the same valve mechanism and associated syrup tube for dispensino a syrup of a different brix value, one would simply grab the ring-shaped pull-tab 38 with their fingers; remove adaptor 30 from the syrup tube ST; and select an orifice disc 40 with an appropriate orifice size with respect to the brix of the new syrup selected. As stated hereinbefore, with the adaptor structure of the present invention this can be readily achieved without damage to either the interior of the syrup 1~ tube ST orthe orifice disc 40which was previously used.
In an alternative embodiment of the present invention, the orifice disc 40 could be integrally molded from plastic with the end portion 32A of ~ adaptor 30, instead of using separate stainless steel orifice discs.
The invention being thus described, it will be obvious that the same may be varied in many ways.
Such variations are not to be regarded as a :3L3d:~3~1L
departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
