用于套在杯子上隔热防烫。
专利摘要
本文提供了一种用于隔热饮料和食品容器的可折叠空气隔热套。更具体地，可折叠空气隔热套以在杯子周围留下空气袋的方式固定杯子。这提供了改进的温度调节和足够的热绝缘，以帮助用户在杯子内容物的温度引起过热或冷凝的情况下牢固地抓握和处理杯子。因为大多数一次性杯子的底部比其相应的边缘窄，所以在由可折叠空气隔热套固定的杯子的底部朝向更多的空气并因此更大的绝缘。更宽的底部也赋予此类杯子更大的稳定性。支撑环可放置在套内侧的中部，以加强套并防止其在用户握持时塌陷。套也可以短，以便隔热杯子的中间部分。可打印材料也可附着在可折叠空气隔热套的外表面上，用于广告或其他目的。可折叠空气隔热套的一些实施例包括盖子，以进一步改进热绝缘。
Original abstractA foldable air insulating sleeve for insulating beverage and food containers is herein provided. More particularly, the foldable air insulating sleeve secures a cup in a manner that leaves a pocket of air surrounding the cup. This provides for improved temperature regulation and sufficient thermal insulation to assist the user in firmly grasping and handling the cup despite excess heat or condensation caused by the temperature of the cup's contents. Because the bases of most disposable cups are narrower than their respective rims, more air and thus greater insulation is found towards the bottom of cups secured by foldable air insulating sleeves. The wider base also gives such cups more stability. Support rings may be placed medially in on the inside of the sleeve to strengthen the sleeve and prevent it from collapsing when held by a user. The sleeve may also be short so as to insulate a medial portion of a cup. Printable material can also be affixed on the foldable air insulating sleeve's outer surface for advertising or other purposes. Some embodiments of the foldable air insulating sleeve include a lid to further improve thermal insulation.
