    • A lightweight container having a readily removable corrugated sidewall. The inner ply of the sidewall is a corrugated sheet having a selected length and width. A bottom wall member is positioned adjacent the lower axial edge of the inner sheet. A flat outer sheet, of selected length and a width greater than the width of the corrugated inner sheet, is joined to the inner sheet to define the outer ply of the sidewall. The outer sheet projects beyond the lower edge of the inner sheet and is folded against and secured to the bottom wall member, to thereby restrain movement of the bottom wall member. A frangible joint is defined along which the sidewall can be severed from the bottom wall without severing the corrugated inner wall, so that the inner wall adds rigidity without interfering with the ready removal of the sidewall. In the preferred arrangement, the adjacent ends of the inner sheet are in a substantially abutting and unsealed relationship to assist in the opening of the container. A portion of the outer sheet also forms pull-tab means which facilitates the removal of the sidewall from the bottom wall. Further, in the preferred embodiment, the engaged portions of the sheets and bottom wall member are coated with a heat sensitive coating which is self-adhering upon the application of heat in a selected temperature.
    • 具有容易拆卸的瓦楞侧壁的轻质容器。 侧壁的内层是具有选定长度和宽度的波纹片。 底壁构件邻近内片的下轴向边缘定位。 所选长度和宽度大于波纹状内片的宽度的扁平外片与内片接合以限定侧壁的外层。 外片突出超过内片的下边缘并被折叠并固定到底壁构件,从而抑制底壁构件的移动。 限定了一个易碎接头,通过该接头可以将侧壁从底壁切断,而不会破坏波纹内壁,从而内壁增加了刚度,而不会干扰侧壁的准备。 在优选的布置中,内片的相邻端部处于基本上邻接和未密封的关系,以帮助开启容器。 外片的一部分还形成拉片装置,其有助于从底壁移除侧壁。 此外,在优选实施例中,片材和底壁构件的接合部分涂覆有热敏涂层,其在选定温度下施加热量时自粘结。

    • Apparatus for lubricating and curling a rim of a paperboard container includes a housing block defining a central recess sized and configured to accept therein a rim of a paperboard container to be curled. An annular curling channel is disposed in the recess for curling the rim of the paperboard container in response to relative advancing movement between the paperboard container and the housing block. The housing block also defines an annular liquid channel concentrically disposed in surrounding relationship to the annular curling channel for distributing lubricating liquid. A porous liquid transfer ring is attached to the housing block in covering relationship to the annular liquid channel so that lubricating liquid supplied to the liquid channel comes into contact with the liquid transfer ring. The liquid transfer ring includes a circular edge surface which defines a central opening such that the liquid transfer ring extends at least partially over the curling channel. In use, the rim of the paperboard container comes into wiping contact with the central opening of the liquid transfer ring so that lubricating liquid is transferred thereto prior to the rim being curled in the curling channel.
    • 用于润滑和卷曲纸板容器的边缘的装置包括限定中心凹部的壳体块,该中心凹部的尺寸和构造适于在其中容纳卷曲的纸板容器的边缘。 环形卷曲通道设置在凹槽中,用于响应于纸板容器和壳体块之间的相对前进的运动而卷曲纸板容器的边缘。 壳体块还限定了环形液体通道,同心地设置成与环形卷曲通道的环绕关系,用于分配润滑液体。 多孔液体传递环以与环形液体通道相关的方式附接到壳体块,使得供应到液体通道的润滑液体与液体传递环接触。 液体转移环包括限定中心开口的圆形边缘表面,使得液体转移环至少部分地延伸到卷曲通道上方。 在使用中,纸板容器的边缘与液体传送环的中心开口擦拭接触,使得在边缘卷曲在卷曲通道中之前将润滑液转移到其上。
