    • An easy-open composite container has a membrane-type closure and includes a laminated tubular body member of composite materials having a predetermined laminated strength. The body member includes a bodywall portion and a liner portion positioned inside the bodywall portion and forming an inside surface of the body member. An outwardly-rolled rim portion is formed at the upper area of an open upper end of the tubular body member and the liner portion forms a top surface of the body member open upper end and an outside surface of the outwardly rolled rim portion. A cut extends circumferentially around a segment of the outside surface of the rim portion and extends radially-inwardly through at least a part of the liner portion. A membrane closure covers the open upper end of the body member and has an outwardly extending tab portion positioned over the cut in the rim portion of the body member. A bond is formed between the top surface of the body member open upper end and the membrane member for hermetically closing such open upper end. This bond has a predetermined strength greater than the laminated strength of the tubular body member and sufficient to prevent leakage caused by internal pressure within the container. With the above construction, the composite container can be easily opened by pulling the pull tab portion of the membrane closure member which causes radial delamination of a segment of the body member rim portion at the cut in the rim portion to provide an easy start for removing the membrane member with the delaminated rim portion segment from the remainder of the body member rim portion of the container.
    • 容易开放的复合容器具有膜型封闭件,并且包括具有预定层压强度的复合材料的层压管状体部件。 主体构件包括主体部分和位于主体壁部内的衬垫部分,并形成主体部件的内表面。 在筒状体部件的敞开的上端的上部区域形成向外卷边的边缘部分,并且衬套部分形成主体部件打开的上端的上表面和外卷边缘部分的外表面。 切口围绕边缘部分的外表面的部分周向延伸并且径向向内延伸穿过衬套部分的至少一部分。 膜封闭件覆盖本体构件的敞开的上端,并且具有定位在主体构件的边缘部分中的切口上方的向外延伸的突片部分。 在主体部件打开的上端的顶表面和用于气密地关闭这样的敞开的上端的膜部件之间形成结合。 该键具有大于管状体部件的层压强度的预定强度,并且足以防止容器内的内部压力引起的泄漏。 通过上述结构,可以通过拉动膜关闭构件的拉片部分来容易地打开复合容器,该部分在边缘部分的切口处引起主体构件边缘部分的段的径向分层,以提供容易的开始以移除 该膜构件具有与容器的主体构件边缘部分的其余部分分离的边缘部分。

    • A multi-ply tubular container for products is provided having a first ply wrapped into a tubular shape and having an inner surface and a second ply wrapped into a tubular shape and having an outer surface positioned in face-to-face contact with the inner surface of the first ply. At least one of the first and second plies is a body ply formed of fibrous paperboard. A foamed adhesive is placed between the inner surface of the first ply and the outer surface of the second ply. The foamed adhesive reduces moisture contact with the paperboard body ply and results in increased container strength and lower manufacturing costs. The foamed adhesive is preferably a foamed aqueous adhesive. The foamed adhesive may be a substantially pure resin adhesive or a mixture of a resin and at least one filler. The two plies may comprise a paperboard body ply and a liner ply adhered together using a foamed adhesive placed therebetween. Additional layers, such as additional paperboard plies or label plies, may also be added to the tubular container and adhered using a foamed adhesive. An apparatus and method for constructing tubular containers is also provided.
    • 提供了一种用于产品的多层管状容器,其具有包裹成管状形状的第一层,并具有内表面和第二层,其包裹成管状,并且具有与内表面面对面地定位的外表面 的第一层。 第一和第二层中的至少一个是由纤维纸板形成的主体层。 泡沫粘合剂被放置在第一层的内表面和第二层的外表面之间。 泡沫粘合剂减少与纸板体层的水分接触,并且导致增加的容器强度和较低的制造成本。 发泡粘合剂优选为发泡水性粘合剂。 发泡粘合剂可以是基本上纯的树脂粘合剂或树脂和至少一种填料的混合物。 两层可以包括布置在其间的泡沫粘合剂的纸板主体层和衬垫层粘合在一起。 另外的层,例如附加的纸板层或标签层,也可以加入到管状容器中并使用泡沫粘合剂粘合。 还提供了一种用于构造管状容器的装置和方法。
