    摘要： An insulating container comprising a container body having at least one side wall and a bottom wall with the side wall including a base layer, an insulating layer on at least a portion of the base layer and a printed pattern, mineral oil application or combination thereof on at least a portion of the surface of the insulating layer is disclosed wherein a thickness of the insulating layer is controlled by the printed pattern and/or mineral oil on the selected portion of the insulating layer. Similarly, stock material incorporating the present invention includes a base layer, an insulating layer formed on at least a portion of the base layer and a printed pattern printed on and or mineral oil applied to the insulating layer is disclosed wherein the thickness of the insulating layer is again controlled by the printed pattern and/or mineral oil on the portion of the insulating layer. The container may be formed of pre-manufactured stock material, by unexpanded stock material or by forming a container body from a paper or paperboard material including a bottom wall and at least one side wall, coating at least the side wall portion of the container body with a thermoplastic synthetic resin film and subsequently printing a pattern on the surface of the thermoplastic synthetic resin film. Once formed, the container is heated at a predetermined temperature for a predetermined time period sufficient to form a heat-insulating layer on the outer surface of the container by expanding the thermoplastic synthetic resin film. The expansion of the thermoplastic synthetic resin is controlled by a thickness of the printed pattern placed thereon, the mineral oil coating or a combination thereof.

    摘要翻译： 一种绝缘容器，包括容器主体，其具有至少一个侧壁和底壁，侧壁包括基底层，基底层的至少一部分上的绝缘层和印刷图案，矿物油应用或其组合 公开了绝缘层表面的至少一部分，其中绝缘层的厚度由绝缘层选定部分上的印刷图案和/或矿物油控制。 类似地，结合本发明的原材料包括基底层，形成在基底层的至少一部分上的绝缘层和印刷在其上的印刷图案或施加到绝缘层上的矿物油，其中绝缘层的厚度 再次由绝缘层部分上的印刷图案和/或矿物油控制。 容器可以由预先制造的原料，未膨胀的原料或由包括底壁和至少一个侧壁的纸或纸板材料形成容器主体，至少涂覆容器主体的侧壁部分 然后在热塑性合成树脂膜的表面上印刷图案。 一旦形成，将容器在预定温度下加热预定时间，足以通过膨胀热塑性合成树脂膜在容器的外表面上形成绝热层。 热塑性合成树脂的膨胀由其上放置的印刷图案的厚度，矿物油涂层或其组合来控制。
