Beverage enhancer
First Claim
1. A device for generating a head on a beverage in a sealed container when the container is opened, comprising a substantially hollow capsule having a first aperture, a second aperture remote from the first aperture, and ballast means forming part of or carried by the capsule, the capsule being such that it will float in a liquid with the first aperture above the liquid surface and the other immersed, wherein liquid can enter the capsule through the immersed aperture, the mass of liquid entering the capsule acting to cause the capsule to rotate at least to the extent that the respective conditions of the two apertures are reversed and the interior of the capsule forming with the liquid therein a liquid lock when the latter is rotated, to inhibit the further ingress of liquid, and trap a volume of gas therein which is available to jet into the beverage when the can is opened.

Abstract
A device for generating a head on a beverage in a sealed can, when the can is opened, comprising a hollow capsule with first and second compartments communicating via tubes with apertures respective each on the opposite side of the capsule from the side of the chamber with which the tube communicates, and a ballast means for orientating the capsule in a position such that, as one chamber charges with liquid, the capsule is caused to rotate and trap a volume of air therein. The capsule may be cylindrical or more preferably spherical in external shape.

10. A device for enhancing head formation on a beverage in a sealed container, when the container is broached, wherein:
-
(1) the hollow capsule (10) is divided internally into two chambers (14,
16),(2) the first aperture (22) in the capsule wall communicates via the tube (18) with one chamber (14) of the two chambers, (3) the second aperture (26) in the capsule wall communicates with the second chamber (16) of the two chambers, (4) a venting aperture (30) is provided in the capsule wall also communicating with the said second chamber (16), and (5) the buoyancy of the capsule (10) is selected so that it will float in the beverage with a part of its volume submerged below the surface of the beverage and so that the said first aperture (22) and the venting aperture (30) are above the surface of the beverage and the said second aperture (26) is below the surface, whereby the second chamber (16) will fill with beverage and the first chamber (14) will be pressurised with gas at whatever pressure exists above the surface of the beverage, and wherein the position of the second chamber (16) within the capsule is such that as it fills with beverage the capsule (10) is caused to rotate so that the first aperture (22) becomes immersed and the gas in the first chamber (14) is trapped therein. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
