Abstract

A portable dispenser is described to apply to a conventional carbonated beverage container and provide the convenient dispensing of contents while maintaining the gas of the beverage until it is fully consumed. The dispenser is composed of an assembly body for screwing onto a conventional carbonated beverage container such as one, two or three liter PET containers and sealingly attached to each other. The assembly body contains a tubular assembly extending from the bottom of the beverage in the container to the outlet of the dispenser, with a spring-loaded valve mechanism responsible for compressing the tube into the closed position and manually operable to allow control of the flow of the drink. The assembly body includes a single pressure regulator and a CO2 cartridge in a cartridge holder to provide a pressure regulated source of CO2 to the beverage container.

Description

The present invention relates to the field

  soft drink distributors and more particularly

  mainly pre-mixed soft drink dispensers. In recent years, increasing amounts of non-alcoholic soft drinks have been sold for domestic consumption in increasingly large containers, as opposed to smaller canisters and bottles containing individual rations. Currently, a large amount of non-alcoholic beverage is sold in PET bottles (polyethylene terephthalate) of two

  liters for domestic consumption. Such bottles--

  they are light and disposable and do not present a problem

  safety problem if they are dropped, etc. However,

  the repeated opening of such bottles for

  from time to time, allows more carbon dioxide to escape, resulting in a significant portion of the non-alcoholic drink becoming

gaseous before being consumed.

  To avoid this problem on these containers and other containers of gaseous beverages, various devices have been proposed to be mounted on the top of the bottle to maintain the carbon dioxide pressure on the soft drink at any time, and to distribute the same. when you wish. For example, the Belgian patent

  No. 743485 discloses a device which has a dispensing valve

  bution at the outlet of the soft drink and a separate valve for carbon dioxide to add more carbon dioxide to the container when the press! on inside drops more than desired. In Austrian breve No. 144111, a pressure regulator is used to control the carbon dioxide pressure on the non-alcoholic beverage. See also United States Patent No. 3,976,221 for another form

pressure regulator.

  In the distribution of highly carbonated non-alcoholic beverages, foaming is frequently a very serious problem. The amount of foam that will be obtained will vary with the circumstances and the dispensing devices used, although in all cases foam is an undesirable effect, since foam makes it difficult to fill a glass, and of course, foam represents the release of the dioxide

  previously dissolved carbon from the non-alcoholic beverage

  This gives a non-carbonated beverage remaining after the fall of the foam. Thus, most non-alcoholic beverage dispensing equipment is designed with this problem in mind. In this regard, see for example, the two beads in the soft drink distribution line in U.S. Patent No. 3,976,221. In some cases, the foam is caused

  by spraying the non-alcoholic soft drink through

  towards small, high-speed openings such as a small mechanical valve of a certain type and / or with thin edges. Techniques to avoid this include such things as the use of two small balls, where normal viscosity effects will at least somewhat limit the speed of the non-alcoholic soft drink through the small space between the balls and

  the tubular element in which they are mounted.

  In other examples however, such as

  in the case of excess gas, at least for the temperature

  current erasure of the moment in the non-alcoholic soft drink, a significant release of carbon dioxide is inevitable, when the pressure on the drink

  non-alcoholic gas is reduced to atmospheric pressure

  phérique, no matter how slowly this is achieved.

  As a specific example, if you open a new bottle of carbonated soft drink at room temperature

  without the slightest jolt, the non-alcoholic beverage

  will release bubbles from the very beginning violently

  because the non-alcoholic beverage contains consid-

  significantly more dissolved carbon dioxide than the liquid can hold under atmospheric pressure. Trying to dispense a soft drink on carbonate for its current temperature will result in a large foam formation and the use of some form of flow reducer, even for the purpose of accumulating losses by viscosity, only strengthens the problem

  foam, since the formation of foam in the pas-

  distribution serves only to tend to mitigate the effect, resulting in the giclage of liquid non-alcoholic beverage to achieve a more complete action even of

separation of carbon dioxide.

  The object of the present invention is to provide a pressure-controlled, particularly low-cost, non-alcoholic beverage dispenser having a particularly low pressure regulator therein.

  simple and one of a kind, and having a system of dis-

  which will minimize the foam under essentially all conditions, which will open again in the case of excess pressure to prevent the explosion of the soft drink container due to a failure of the pressure regulator to completely interrupt in all case and / or failure of the first valve

  pressure safety for any reason.

  A portable dispenser is disclosed for adapting to a conventional gaseous drink container and for providing for convenient dispensing of such contents while maintaining the gas of the beverage until fully consumed. The dispenser is composed of an assembly body for screwing onto a conventional soft drink container such as one, two or three liter PET containers and sealingly attached

  to one another. The assembly body contains an assem-

  tubular wort extending from the bottom of the beverage into the container at the outlet of the dispenser, with a mechanism

  spring loaded valve to compress the tube into

  closed and manually operable to allow

  to control the flow of the beverage. The assembly corps

  The present invention includes a single pressure regulator and a CO cartridge in a cartridge holder for providing a controlled pressure CO 2 source to the beverage container. Other features, objects and advantages of the present invention will become apparent upon reading the

  detailed description which will follow and with regard to

  annexed examples given by way of non-limiting examples and in which: Figure 1 is a perspective view of the

present invention.

  along line 2-2 of Figure 1.

  Figure 6 is a partial section taken on

  along line 6-6 of Figure 5.

  Referring first to Figure 1, a perspective view of the present invention may be observed as mounted on a two liter PET soft drink bottle. The dispenser of the present invention is generally characterized by an assembly body 22 having a lower portion 24 which

  screw on the top of the non-alcoholic beverage bottle

  a lower portion 26 of the front side forming a dispensing spout, a portion of the rear side 28 containing a small carbon dioxide cartridge and a dispensing lever 30 for controlled dispensing of the

  non-alcoholic drink through a tube in the spout 26.

  Also coupled to the body of the assembly 22, a flexible tube 32 descends into the bottle 20 to a position close to the bottom so as to allow the operation

  of the dispenser with the bottle upright.

  Figure 2 is a partial sectional view of the distributor taken along the line 2-2 of Figure 1. The assembly body of Figure 1 is composed of a body member 34 which provides the distributor

  its basic structure. As shown in Figure 2, the

  body 34 includes a forward 36, integrating

  threaded internally, for screwing on the bottle, with a sealing element 38 housed in a groove at

  top of the projection providing the final seal of

  with the top of the PET bottle. The tube 32 (see also Figure 1), a polyethylene tube in the preferred embodiment, passes through a hole in the body member at the top of the bottle 20 to continue upward and curl toward the before, to the region of the spout 26 in a slideway 42 located in the body member. The end 44 of the tube 32 is extended in a silicone rubber member 46 (see also FIG. 4) lying in the extension of the slideway 42 and extending downwards to a position situated approximately at the level of the advanced 26 spout-shaped body member, the advanced 46 silicone rubber having a flange 48 resting in a complementary slide 50 in the body member to locate it. In the preferred embodiment, the polyethylene tube 32 has an inside diameter of 0.078 inches (1.98 mm), with the silicone rubber member 46 dropping the end to define a continuous pathway extension defined by the diameter. the inside of the polyethylene tube 32 via a flaring or increasing cross-sectional passage towards the farthest end 52, having the inner diameter of 0.156 at the end of the outlet. While the flare can vary from the given value provided that the rate of change of the surface is progressive and in fact a satisfactory operation is obtained without flaring, the inner diameter of the tube 32 is more critical. In particular, if the inner diameter of the tube is much larger, the flow velocity will be too high and unnecessary foam will form in the

  container concerned. Also, the volumetric flow rate

  will be too high to cause a user to throttle the outlet with the valve, causing the drink

  non-alcoholic to squirt and trigger an excess foam

  sive o the dispensing tube is partially pinched.

  On the other hand, if the diameter of the tube 32 is much smaller, not only will the volumetric flow rate be laboriously slow, but the transit time of the non-alcoholic beverage in the dispensing tube will be so long as the unavoidable foam due to an excess of gas will develop more fully inside, which, at

  because of the restricted flow area, can trigger

  expensive extra useless foam. Therefore, while the diameter of 0.0078 is preferred, a diameter varying approximately 10% around this value is generally acceptable, with a diameter of more than about 20% of this value exceeding the normal range.

acceptable.

  This configuration, as will be seen in the following, includes an important aspect of the present invention since it provides a very simple, yet effective, solution to the foam problem, and at the same time provides a very low distribution valve. cost that can also act as a safety valve in case of failure of both the pressure regulator

  and the primary safety valve, yet to be described.

  In particular, the distribution lever 30, supported by rotation axes 54 integral with the body member 34 on one side and the cover plate 56 (see FIG. 1) on the other side, is actuated by the spring pressing member 58 against the silicone rubber member 46 to exert pressure thereon to prevent passage of all the soft drink therethrough and out of the outlet at normal operating pressures within the container. non-alcoholic beverage, although essentially open at once to evacuate the system in the case where the pressure greatly exceeds the normal pressure of the

system operation.

The flow rate in the tube 32 is still sufficiently fast, so that, if there is an excess of gas in the non-alcoholic soft drink in the container 20, the non-alkaline soft drink will pass through the tube 32 and the exit section 46 before a significant separation of the

  carbon dioxide with the non-alcoholic soft drink

  can not take place because of the reduction in

  pressure. Although such an excess of gas necessarily leads to

  As a result of foam or muffler formation on the non-alcoholic carbonated beverage in the glass, this amount of foam or false-collar would occur even if the non-alcoholic soft drink had been poured from a freshly opened bottle. . Finally, the flow rate of the non-alcoholic soft drink during dispensing is also low enough to avoid

  some details are visible only in certain figures, a specific attention will be directed towards the

  specific figures in the following description. As

  it can best be seen in Figures 2, 5 and 6, a

  second valve element 94 is located in the green opening

  Ticale 78, while being displaceable although impervious as compared to the opening tor intic 96. The secnd valve element 94 whose body is located above the first valve element 82 (Figures 2 and 5), includes, solidaire from it, a pair of arms 93 (Figures 3 and 6) extending beyond the side of the portion of the first valve member 82, extending to the cross-openings 76 and 78 to support a closure member valve 100 under the valve seat 90 (Figures 2, and 6). The upper part of the element 94 is hollow, having an opening 102 through its center with a ball 104 being pressed against the opening to seal by the compression spring 106 held in position by an element cap 108 fixed by pressure in the element 94, the hat element in turn
