具有增强的阻挡性能的气密密封的纸板容器
摘要：
本发明公开了一种具有增强的阻挡和密封性能的气密密封的纸板容器，所述容器可通过对于内部系统较为有效和经济的方法来制备。所述容器包括容器主体组件、底部和与主体组件气密密封的顶盖。所述容器主体由包含纸板(201)的坯料形成，所述纸板(201)的一个表面涂有第一密封剂层(202)，而相对表面涂有阻挡层(203)和在所述阻挡层(203)之上施用的第二密封剂层(204)。对于预定的宽度，将坯料的一个纵向端切削成预定的厚度，折叠于坯料上，并密封以形成折叠的纵向端。接着，将坯料的折叠的纵向端重叠于坯料的另一个纵向端之内，以形成主体接缝，随后将该主体接缝密封，以提供中空的容器主体。
摘要（英）：

A container body component for forming a hermetically sealed paperboard container, the container body component being formed from a blank and including an upper end and a lower end and, the blank comprising: a) paperboard having a first side and a second side, b) a first sealant layer on the first side of the paperboard, c) a barrier layer on the second side of the paperboard, and d) a second sealant layer applied over the barrier layer, i) the blank having a first and a second longitudinal ends, the first end being skived to a predetermined thickness for a predetermined width, the skived portion being folded over onto the blank to form a folded first longitudinal end, the body component having an overlapped seam with the folded first longitudinal end of the blank inside the second longitudinal end; and ii) a bottom component sealed to the lower end of the body component; characterised in that the folded over skived portion is sealed to form an edge.
