BEVERAGE PACKAGE AND A METHOD OF FORMING SUCH A PACKAGE |
摘要 |
A sealed beverage package has a bottle 1, a neck 4 of which provides a narrow mouth 5. A hollow insert 7 is submerged in beverage 13 in the bottle. A headspace 14 in the bottle is at a pressure greater than atmospheric and when the package is opened to de-pressurise the headspace 14, gas and/or liquid under pressure in the insert 7 is ejected through an aperture 8 into the beverage to cause a head of froth to develop on the beverage 13. The insert 7 is retained in position by an open framework 9 of struts which extend between the insert and a retaining ring 11 that frictionally engages in a bore 6 adjacent to the mouth 5 of the bottle. The insert 7 can be attached to the framework 9 or formed integral therewith.
