8899281
The present invention relates to drinking vessels and, in particular, to glasses for beer.
Conventionally, beverages are dispensed into drinking vessels simply by pouring the beverage into the mouth of the vessel. Draught beer, for example, is generally dispensed from a beer tap directly into the mouth of a beer glass.
Most beers are carbonated with carbon dioxide. The carbon dioxide dissolved in the beer is what makes the beer fizzy. When beer is poured into a glass from a beer tap, the agitation of pouring and the turbulence created by the stream of beer hitting the bottom of the glass as it falls from the tap causes some of the carbon dioxide to bubble out of solution, forming a head of foam on the glass of beer. However, if the beer is dispensed by someone who is not particularly skilled in the art of beer pouring, an excessive head of foam may be formed on the upper surface of the beer. This may also occur when pouring carbonated soft drinks.
Other beers, such as stouts, are less fizzy than carbonated lager beers, as they contain less dissolved carbon dioxide. However, these beers, once poured, require “settling time” to allow the turbulence created in the beer during pouring to subside and to allow a creamy head to form on the beer. The time involved in correctly pouring a glass of stout can be up to three minutes, including settling time.
It is therefore desirable to allow beverages such as beer to be dispensed in a such a way that the turbulence and agitation created in the beverage during dispensing is reduced, thereby making correct dispensing of the beverage easier and reducing settling time required. A number of techniques have been proposed.
British Patent No. GB2353785 describes a nozzle for a beer dispenser, which is inserted into a beer glass to dispense beer near the bottom of the glass. The nozzle is operated by pressing the bottom of the glass upwards against a spring bias to open apertures in the nozzle.
British Patent No. GB2178003 relates to a method of dispensing beer at the bottom of a glass and describes a dispensing nozzle is adapted to reach the bottom of the glass.
British Patent No. GB2322691 relates to a beverage dispenser with a long outlet spout, which in use extends to the bottom of a glass into which the beverage is to be dispensed. Beverage is dispensed when the end of the spout is pressed against the bottom of the glass.
One problem associated with these arrangements is that a nozzle must be inserted into the glass so that it extends to the bottom thereof. The nozzle is thus immersed in the beer in the glass. When the next glass of beer is dispensed, the nozzle, along with its coating of stale beer, is inserted into the new glass, which could be unhygienic.
An object of the invention is to provide an alternative method for filling a drinking vessel at the bottom, and a drinking vessel suitable for use therein. Another object of the invention is to provide an arrangement which overcomes the problems associated with the prior art.
According to the present invention, there is provided a drinking vessel comprising a base and at least one wall extending therefrom, wherein the base and the wall together define a chamber for receiving a beverage; characterised in that the vessel further comprises a sealable aperture provided adjacent the base for filling the chamber with a beverage.
Preferably, the sealable aperture is provided in the base of the vessel. Alternatively, the aperture may be provided in the wall of the vessel close to the base.
An advantage of this arrangement is that the vessel can be filled through the aperture in the base, rather than by pouring the beverage through the mouth of the vessel in the conventional manner. Filling the vessel at the bottom in this way reduces the turbulence induced in the beverage as it is dispensed into the vessel. This is particularly advantageous when dispensing carbonated beverages such as beer and “fizzy” soft drinks, as it prevents an excessive head of foam from being produced at the top of the beverage. The beverage can thus be dispensed more quickly than is possible with conventional arrangements. It also reduces the risk over overflowing the vessel due to a large amount of foam being formed in the beverage as it is poured. When used for beers which require settling time, such as stouts, the drinking vessel of the present invention reduces the settling time required. For a pint of stout dispensed into an appropriately sized drinking vessel according to the present invention, the total time taken to prepare the beverage is reduced to approximately one minute, including settling time. The beverage is consumed by a user through the mouth of the vessel in the usual manner.
In a preferred embodiment of the invention, the drinking vessel further comprises a non-return or directional valve disposed in said aperture, wherein the valve allows a beverage to be dispensed into the vessel through the aperture but prevents the beverage from escaping from the vessel through the aperture.
Preferably, the non-return valve is of the type comprising a silicone membrane.
The strength of the valve may be selected to ensure that it can withstand the pressure exerted on it by liquid in the vessel when the vessel is full. For example, where the vessel is a pint glass, the valve is ideally capable of withstanding at least the pressure exerted on it by one pint (0.568 liters) of liquid. Preferably, the valve is capable of withstanding pressure in excess of that exerted by liquid in the vessel when the vessel is full.
One advantage of this arrangement is that that the aperture is automatically or self sealed once the beverage has been dispensed through the aperture and the non-return valve. The valve allows flow of liquid in one direction only, that is, into the vessel, thereby preventing leakage from the vessel while the beverage is being consumed.
A further advantage of the arrangement is improved hygiene over previously suggested arrangements which require a long spout or nozzle to be inserted into the vessel, through beverage already dispensed. Where a nozzle is used to dispense beverage into the vessel, the membrane has the effect of wiping the nozzle as it inserted into the base of the vessel. The present invention also allows the beverage to be dispensed into the vessel without requiring a nozzle to be inserted therein. An upwardly directed, pressurized stream of beverage, in the manner of a drinking fountain, may be provided. The pressure of the stream alone is sufficient to open the valve and allow beverage to be dispensed into the vessel, without any spout or nozzle entering the vessel.
In one embodiment, the drinking vessel is a beer glass. The vessel may be made from a plastic material.
Preferably, the at least one wall of the vessel is substantially rigid. The base of the vessel may also be rigid. This prevents liquid being expelled from the vessel through the valve by squeezing the walls of the vessel. This allows the user to grip the vessel as he would a regular glass without fear of accidentally forcing liquid out of the vessel through the valve in the base.
According to a second aspect of the invention, there is provided apparatus for dispensing a beverage, comprising an inlet portion connectable to a pressurised beverage supply; at least one outlet portion arranged to dispense the beverage; and conduit means provided between said inlet portion and said outlet portion to provide a fluid path for said beverage therebetween; characterised in that the apparatus is operable to allow the beverage to pass from the inlet portion to the outlet portion under pressure through said conduit means such that the beverage is dispensed at said outlet portion in a substantially upward direction.
The apparatus described above may be used with the drinking vessel of the present invention. The drinking vessel is placed over an outlet portion such that the beverage is dispensed into the vessel through the sealable aperture in the base thereof.
In one embodiment, the apparatus comprises a plurality of outlet portions to allow several drinking vessels to be filled simultaneously.
In one embodiment, the or each outlet portion is engageable with an aperture provided in the base of a drinking vessel. The apparatus may include a nozzle associated with the or each outlet portion for insertion into the drinking vessel through a sealable aperture in the base to dispense beverage into the vessel. Each nozzle may be provided with at least one dispensing aperture. Preferably, each nozzle is provided with a plurality of dispensing apertures arranged around the circumference thereof, such that the beverage is dispensed in a substantially upward and outward direction from the nozzle.
Alternatively, an upwardly directed, pressurized stream of beverage may be dispensed at the or each outlet portion, similar to a drinking fountain. Where the drinking vessel is provided with a non-return valve disposed in the aperture, the pressure of the stream of beverage is sufficient to open the valve and allow beverage to be dispensed into the vessel.
The apparatus may be operable to allow the beverage to be dispensed at a relatively slow rate initially when the vessel into which the beverage is to be dispensed is empty. The apparatus may also be operable to allow the dispense rate to be increased once the beverage has reached a predetermined level in the vessel.
The apparatus may further comprise automatic activation means to allow a beverage to be dispensed automatically. The automatic activation means may comprise a card reader arranged to read a swipe card and to dispense a beverage in accordance with information contained on the swipe card. Alternatively, the automatic activation means may comprise a receiver arranged to receive a signal from a remote control device and to dispense a beverage in accordance with the received signal.
The present invention also relates to a method for dispensing a beverage, comprising the steps of providing a drinking vessel having a sealable aperture in a base thereof and dispensing a beverage into the vessel through the sealable aperture in the base.
In one embodiment, the method further comprises the step of sealing the aperture in the base of the vessel. However, in the preferred embodiment, the drinking vessel comprises a non-return valve disposed in the aperture as described above, and the aperture is, therefore, automatically sealed by the valve after the beverage has been dispensed.
The method may further comprise the steps of positioning the drinking vessel at an outlet portion of the apparatus described above, and operating the apparatus to dispense the beverage into the vessel in a substantially upward direction. The step of positioning the drinking vessel may include engaging the aperture in the base of the drinking vessel with the outlet portion of the apparatus, for example, by inserting the nozzle into the aperture.
