<p>A drinking tube having (10, 70) either a polygonal cross section of constant transverse cross-sectional area, or having an enlarged portion (75) which generally has a part of constantly varying transverse cross-sectional area. In this way, when the drinking tube (10, 70) is inserted into a beverage container, a gap (25, 85) is always formed around the outside of the tube which allows the container (30, 90) to vent. A suitable container may typically include a metal container end (110) having a separate panel which is fixed to a central member, the panel (150) being rupturable by a drinking tube (10, 70, 170). In use, when attached to the container may be consumed in a hygienic manner, without risk of contamination of the beverage by any part of the panel which is pushed into the container on rupturing.</p> |
