摘要： A multi-ply tubular container (10) for products is provided having a first ply (13) wrapped into a tubular shape and having an inner surface and a second ply (14) wrapped into a tubular shape and having an outer surface positioned in face-to-face contact with the inner surface of the first ply (13). At least one of the first and second plies is a body ply formed of fibrous paperboard. A foamed adhesive (21) is placed between the inner surface of the first ply (13) and the outer surface of the second ply (14). The foamed adhesive (21) reduces moisture contact with the paperboard body ply and results in increased container strength and lower manufacturing costs. The foamed adhesive (21) is preferably a foamed aqueous adhesive.

摘要： A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky. The body ply and a polymeric liner ply having a moisture barrier layer are then passed through a nip to adhere the liner ply to the body ply and are wrapped around a shaping mandrel to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface. The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape. A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped. Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply.
摘要翻译：提供一种制造用于食品的多层管状容器的方法，包括以下步骤：将水性粘合剂施加到纸板体层的表面，然后加热水性粘合剂以蒸发部分含水量并使粘合剂基本上发粘。然后将身体帘布层和具有防潮层的聚合物衬垫层通过辊隙以将衬垫层粘合到身体帘布层上，并缠绕成形心轴以形成管状容器。因此，可以制造有利的管状容器，其具有由纸板形成的主体层，其被包裹成管状形状以限定内表面。在被包裹之前，身体帘布层限定了预定的圆周长度，其对应于当被包裹成管状形状时对应于身体帘布层的一圈。聚合物衬垫层被粘附到主体帘布层的内表面，并且在包裹之前限定与身体帘布层相同的圆周长度。因此，当主体帘布层被包裹成管状时，衬垫层被周向地压缩，并且由于衬垫层的周向压缩而在包裹之后有利地具有起皱的表面光洁度。

摘要： Spirally wound easy-open containers (10) comprise a spirally wound body wall (30) having overlapped edges (34, 36) and have capabilities and benefits associated with conventional butt jointed containers. The overlapped edges (34, 36) of the body wall (30) define an easy-open seam (20) extending helically between the ends of the container. A temporary adhesive between the overlapped edges (34, 36) of the body wall (30) releasably adheres the overlapped edges (34, 36) of the body wall (30) together and allows for opening of the container along the helical easy-open seam (20). Such easy-open containers (10) can be readily manufactured with only slight modifications to the conventional manufacturing process. Nevertheless, these easy-open containers (10) can provide for material savings in container label construction and can allow for vacuum packaging of food products such as dough.

摘要： An easy-open container (10) for products such as dough has an easy-open seam (18) extending helically between the ends (14, 16) of the container body. A helically wound outer label (12) of flexible sheet material in strip form has at least one longitudinal edge (26) folded onto and bonded to the main body (28) of the label to thereby provide a reinforced longitudinal edge portion (20) of the outer label comprising at least two layers of the flexible sheet material. The reinforced longitudinal edge portion (20) of the outer label (12) is positioned in bridging relation to the easy-open seam (18) of the body wall (38) to thereby maintain the easy-open seam closed and provide a peel strip for exposing the easy-open seam for opening of the container body.
