| 摘要 |
<p>The invention concerns a heat-insulated container (1), preferably a bottle, flask, can or the like, designed to receive directly a product, preferably a food product such as a beverage, introduced or extracted, through an opening (5) closed with a cap (6), in a chamber (4) delimited by an inner wall (2), said container further comprising an outer wall (3) which, with the inner wall, defines a closed volume (24), the major part of said inner wall (2) having a first high heat conductivity and second low heat conductivity. Said container is characterised in that it comprises intrinsic transformation means and mechanical control means (R) for shifting from said first state to said second state. The invention is applicable to heat insulation of beverages to be consumed hot or cold.</p> |
