DETAILED DESCRIPTION OF THE INVENTION

(11) This invention may be embodied based on the following elements, wherein the examples presented herein constitute only examples of the embodiment of the invention without, however, excluding other possible and potentially not described herein but are within the scope of this invention.

(12) The parts of said valve described herein may be manufactured from several materials such as polypropylene plastic or other possible as well as the combination thereof.

(13) The principle of functioning of said valve is based on the fact that the handle (1) comprises a flexible hose (6) positioned internally in the form of “L”, wherein such compression occurs at different positions of the handle (1) in a twist of about 60° on the flexible hose (6) generating different inner volumes in the flexible hose (6). For this operation, the upper hole (9au) must be filled with the metallic rod (9d).

(14) When in the vertical position, 90° in relation to the ground, the handle (1) compresses at the maximum the flexible hose (6) in order to prevent the flow of the beverage. In this position the handle hole (9bl) are filled by the second metallic rod (9c) and the valve is locked so that the container containing the gasified liquid may be transported without the danger of leakage.

(15) When the handle (1) is moved forward in relation to the user, the hose (6) will undergo a displacement that enables a minimal opening in its diameter so that the flow of the beverage is turbulent and the beverage is dispensed with enough foam.

(16) When the handle (1) is moved backward in relation to the user, the compression of the flexible hose (6) is smaller and consequently the flow of the pressurized beverage is more laminar, allowing the liquid outlet with less quantity of foam.

(17) In this sense, one of the purposes of this invention consists of the method for dispensing gasified liquid comprising the steps of: i. Unlocking the handle (1); ii. Positioning the cup or container in which the liquid will be dispensed at the end of the tubular extension (2); iii. Moving the handle (1) forward or backward in relation to the user; iv. Waiting for appropriate time; and v. positioning the handle (1) in the 90° position.

(18) The liquid pressurizing procedure involves the steps of: i. placing the liquid to be gasified into a suitable container with the valve of this invention installed; ii. connecting the cylinder hose (20) to the air valve (3) of the valve main body (7); iii. opening the cylinder register (22) allowing the flow of gas from the cylinder (23) to the liquid; iv. waiting for adequate time; v. closing cylinder register (22); and disconnecting the cylinder hose (20) from the air valve (3).

(19) The connection of the cylinder (23) to said valve occurs through a coupling similar to that used in the calibration of automobile tires. A cylinder hose (20) is coupled to the cylinder (23) through a screw system and the opposite end comprises a gas injection nozzle comprising a clamp (19) similar to that used in tire air minicompressors as the commercially available SH-P 00004 model. Said clamp (19) fits into the valve main body (7) according to this invention directly in a Schrader valve (3) which is a valve used in a tubeless automobile tire as the market model 414R.

(20) Since the ends are properly connected, the cylinder register (22) is opened and the pressurization starts. The gasification may be done with carbon dioxide CO.sub.2 (99.9%), nitrogen N.sub.2 (99.9%), or a mixture thereof.

(21) The gasification time and the final pressure reached indicated in the display (21) will depend on the volume of liquid to be gasified, the type of gas used, the temperature, the material of the container comprising the liquid and the user's interest. If the user desires a thick beer head, it may increase the content of the solubilized gas in the beverage.

(22) In one embodiment, for a 2 L container being 70% filled with the beverage and therefore 30% hollow, the gasification was made at the pressure of 3.5 kgf cm.sup.−2 of CO.sub.2 for 2 seconds, so that the gas pressure (in kgf cm.sup.−2)×volume of the hollow bottle (as percent of the total volume) is equal to or greater than 1 kgf cm.sup.−2.

(23) This gasification procedure may be done in both the commercial establishment and the home environment, following the proper safety requirements.

(24) Once this step is finished, the cylinder (23) is closed, the hose clamp (19) is disconnected from the Schrader air valve (3) and the liquid is ready to be dispensed and consumed.

(25) The use of the Schrader valve (3) allows for a high efficiency in the gasification process and the maintenance of the gasification, since it prevents escape of gas during storage and transport of the beverage over time.

(26) Valve Main Body (7)

(27) The valve main body (7) according to this invention is a single piece which may be plastic, metal or other compatible material.

(28) Said valve main body (7) comprises a nozzle (11) whose inner wall comprises a universal thread (10) compatible with the thread of the container which stores the liquid (18). Said nozzle (11) further comprises a concentric cylindrical piece (11a) whose inner wall comprises a thread (11b) compatible with the reductant thread (14). The front portion of the valve main body (7) is provided with a tubular extension (2) for the outlet of the liquid, positioned at an angle of approximately 30° with respect to the valve main body (7).

(29) At the other end of the valve main body (7), there is a projection of cylindrical shape, of diameter 5 mm and length 1 cm, for the insertion of the Schrader air valve (3), used for the pressurization and gasification of the liquid (18).

(30) The valve main body (7) further comprises an inner channel (3a) that allows the passage of the gas of the Schrader air valve (3) into the container where the liquid (18) is stored.

(31) On the right and left sides of the valve main body (7), there are two small overlapping holes (9au, 9al) of diameter 2 mm each, with 2 mm spacing from each other. The upper hole (9au) is used to hold the handle (1) against the valve main body (7) during handling, so as to allow for its movement. When lower hole (9al) is filled with the second metallic rod (9c), with the handle (1) at 90° position, the flexible hose (6) is fully compressed, and the valve is locked so that the beverage may be transported without danger of leakage. Both the grip of the handle (1) to the valve main body (7) of the valve and the full locking thereof are made by passing the second metallic rod (9c), by main body hole (9al) in the valve and handle hole (9bl).

(32) In the core of the upper portion of the valve main body (7) there is a hollow portion of rectangular shape followed by a hollow semi-ball (8). The handle (1) is fitted in this hollow space and a flexible hose (6) is positioned in “L”. One of the ends of said flexible hose (6) is in contact with the upper end of the pipe (5) and the other end open to the environment.

(33) In one embodiment, said valve is compatible with a growler with the nozzle similar to that of a pet bottle.

(34) In one embodiment, the main body (7) of said valve comprises an outer diameter 3.5 cm and height 3.0 cm, tubular extension of length 6 cm, diameter 4.25 mm, at an angle of approximately 30° with respect to the valve main body (7) and projecting from diameter 5 mm and length 1 cm, rectangular shaped hollow portion with 4.25 mm height and 4.96 mm long, hollow semi-ball (8) of 8 mm diameter, inner diameter of thread diameter 7.14 mm, two overlapping main body holes (9au, 9al) of diameter 2 mm with 2 mm spacing from each other.

(35) In one embodiment, the cylindrical piece (11a) of the valve main body (7) comprises means for coupling the reductant (4) other than a thread.

(36) Handle

(37) The handle (1) according to this invention is a movable portion of said valve that enables the egress of the gasified liquid. The formation of the foam occurs according to the movement of the handle (1) which varies 60°.

(38) Said handle (1) comprises a semi-ball (12) at one end through which the fitting is made in the valve main body (7) according to this invention which comprises a hollow semi-ball (8).

(39) Said handle (1) comprises in the semi-ball two small holes (9bu, 9bl) which correspond to other two small holes (9au, 9al) in the valve main body (7). Such holes (9au, 9bu) are passed through a metallic rod (9d) which allows the handle (1) to move in a total opening of about 60° in the vertical direction.

(40) In one embodiment, the handle (1) according to this invention comprises 46 mm long, 11.07 mm thick having 17.15 mm handle semi-ball (12) radius at one end, 2 mm diameter overlapping handle holes (9bu, 9bl) with 2 mm spacing and beveled edges throughout the piece.

(41) Said handle (1) is locked when it is in the vertical position 90° in relation to the ground (FIG. 9A) and with the handle hole (9al) passed through by a second metallic rod (9c). In this way, the container may be shipped without any danger of leakage of the liquid (18).

(42) When said handle (1) is moved forward in relation to the user (FIG. 9B), it allows the flow of the gasified liquid with high turbulence as in this position it has a high compression level of the flexible hose (6) that is with the inner diameter well reduced.

(43) When the handle (1) is moved backward in relation to the user (FIG. 9C), it allows the flow of the gasified liquid (18) with low turbulence as in this position it has a low compression level of the flexible hose (6), which then presents with increased or completely free inner diameter.

(44) Flexible Hose at “L”

(45) The flexible hose (6) according to this invention is a hose positioned at “L” in the main body (7) of the valve. Such “L” position is due to the fact that one of its ends is connected to the upper end of the outlet pipe (5) and the other end fitted to the tubular extension (2) of the valve main body (7) for dispensing the liquid (18).

(46) The folding of said “L” occurs by passage of said flexible hose (6) by the hollow semi-ball (8) of the valve body 7. Said flexible hose (6) is positioned between the hollow semi-ball (8) of the valve main body (7) and the handle semi-ball (12) of the end of the handle (1). Thus, during movement of the handle (1), the inner diameter of said flexible hose (6) is necessarily changed, reflecting directly in the manner as the gasified liquid (18) is dispensed.

(47) In one embodiment, said flexible hose (6) is a silicone hose.

(48) In one embodiment, said valve comprises a long “L” flexible hose (6) that is partially submerged in the liquid (18) and said valve does not comprise the liquid outlet pipe (5).

(49) Liquid Outlet Pipe

(50) The valve according to this invention comprises a liquid outlet pipe (5) that remains partially immersed in the gasified liquid (18).

(51) In particular, such an outlet pipe (5) must be sufficiently stiff to withstand the external pressure of the gas dissolved in the liquid (18) but flexible enough to allow for the engagement of the reductants (4), (41).

(52) In one embodiment, said outlet pipe (5) is of silicone of outer diameter 8 mm, inner diameter 5 mm and length 30 cm.

(53) Reductants

(54) The use of reductants (4), (41) along the liquid outlet pipe (5) allows for a more accurate control of the outflow of the beverage so as to decrease its turbulence during dispensing. Such reductants (4), (41) allow the valve to actuate in more fine and accurate manner in the customization of the creaminess of the beverage, i.e., in the formation of the foam.

(55) The reductants (4, 41) according to this invention are devices that serve as a function to reduce the pressure of the solubilized gas in the liquid (18) as it passes through the pipe at the time the beverage is taken to leave the less turbulent outflow. Such reductants (4), (41) may have various shapes and be made of different materials and may or may not be of the same shape.

(56) The valve according to this invention comprises an upper reductant (4) positioned at the upper end of the liquid outlet pipe (5), so as not only to allow for the reduction of the turbulence of the liquid flow, but also to allow the connection of the liquid outlet pipe (5) to the valve main body (7) according to this invention through an outer reductant thread (14).

(57) Optionally, the valve according to this invention comprises a lower reductant (41) at the lower end of the liquid outlet pipe (5).

(58) The reductant (4) comprises a rubber ring (16) which assists in the fitting of this liquid outlet pipe (5), preventing its movement with the use of the valve according to this invention.

(59) Said reductant (4) comprises an outer thread (14) for fixation to the liquid outlet pipe (5) and the valve main body (7), and said reductant thread (14) comprises grooves (15) which assist in threading the valve main body (7).

(60) The reductant (4) further comprises an upper cylindrical piece (4a) in which is connected the flexible hose (6) and a lower cylindrical piece (4b) in which the liquid outlet pipe (5) is fixed by means of a simple fitting.

(61) In one embodiment, the upper and lower cylindrical piece (4a) (4b) of the reductant (4) has the same diameter.

(62) In one embodiment, the lower and upper cylindrical piece (4a) (4b) has different diameters.

(63) The reductant (4) further comprises a rubber ring (16) for sealing.

(64) In one embodiment, the valve according to this invention comprises two reductants (4) (41), both of inner diameter 1 mm and length 2 cm both made of metallic material, as shown in FIG. 7.

(65) In one embodiment, the valve according to this invention has only one reductant (41) and a long “L” flexible hose (6), wherein such a reductant (41) is positioned at the immersed end in the liquid (18).

EXAMPLE OF EMBODIMENT

(66) The example of use to be described relates to the use of a 2 l capacity bottle which has been filled with 1.3 l of the beverage, for example chopp, at the usual temperature of consumption.

(67) Once the bottle is filled, the valve was threaded, and the preparation is made for the pressurization of the beverage gasifying system. The FIG. 3A illustrates the threaded bottom portion of the valve, the nozzle.

(68) For the gasification and pressurization, it is necessary to connect the cylinder (23), CO.sub.2 or N.sub.2, to the bottle. To this end, a cylinder hose (20) is used, for example polypropylene (5 mm diameter), wherein one of the ends has a thread coupled to the cylinder (23) and the other is a clamp (19) with an air injector nozzle as used in mini-air compressors for tire, commercially available model SH-P 00004.

(69) The nozzle is coupled to the valve main body (7), which comprises a Schrader air valve (3), which is used in a tubeless automobile tire, the market Model 414R, as shown in FIGS. 7 and 8.

(70) Since the ends are properly connected, the cylinder register (22) is opened and the pressurization starts. The gasification may be done with carbon dioxide CO.sub.2 (99.9%), nitrogen N.sub.2 (99.9%) or a mixture thereof. The recommended pressure is 3.5 kgf cm.sup.−2 for 2 seconds. This procedure may be done in both the commercial establishment and the home environment, following the proper safety requirements. Once this step is finished, the cylinder register (22) is closed, the nozzle is disconnected from the bottle and dispensing of the beverage may be initiated.

(71) For dispensing the beverage, the handle (1) of the valve according to this invention is used, in order to customize the quantity of foam of the beverage.

(72) When in the center position, FIG. 9A, the handle (1) is locked since it exerts maximum compression on the flexible hose (6), so that no liquid flows.

(73) When the handle (1) is moved forward in relation to the user, FIG. 9B, the flexible hose (6) undergoes a modification in its compression that enables a minimal opening of the inner diameter thereof, so that the flow of the beverage is turbulent, enabling the output of large quantity of foam.

(74) When the handle (1) is moved backward in relation to the user (FIG. 9C) the compression of the flexible hose (6) will be in its less compressed embodiment, i.e., more open, so that the flow of the pressurized beverage is more laminar, allowing the liquid to exit, with less quantity of foam.
