公开了一种用于形成具有矩形横截面的液密容器的设备和方法，该容器由单件T形纸板材料坯料形成。纸箱优选地在其一侧包括存取盖板和吸管元件，当手动提起时，该吸管元件暴露吸管元件的端部，用户可以从该端部消耗纸箱的内容物。该设备本质上是紧凑的，具有相对较少的将T形纸箱坯件推进通过多个工作站的传送机构。公开了一种用于将吸管元件和检修面板连续施加至纸箱坯件的新颖方法和装置，其中吸管元件和一段聚乙烯涂覆的聚酯薄膜带在旋转的热封和对准滚筒上自动粘合至纸箱坯件。还提供了用于围绕成形心轴整理多个纸箱坯料的输送机，并且该输送机横向于设备的其余部分定位，从而显着减小设备的总体尺寸。超声波焊接机将容器的侧缝和端盖面板粘合在旋转横杆心轴上，从而消除了密封过程中的任何未对准。基本刚性的传送带传送器运送多个纸箱坯件通过预成型、填充和端部封闭工作站，并且包括用于超声波焊接工艺的多个砧座。另外还提供了弹出机构，其将已填充的纸箱坯件沿着双向路径从刚性输送机弹出，从而消除了使已填充且密封的容器起皱或刺穿的可能性。另外，本发明的设备只需进行微小的调整即可生产不同尺寸的容器。
An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material. The carton preferably includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carton may be consumed by a user. The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carton blank upon a rotating heat sealing and alignment drum. A conveyor for collating a plural number of the carton blanks about a forming mandrel is also provided, and is positioned transversely to the remainder of the apparatus thereby significantly reducing the overall size of the apparatus. An ultrasonic welder bonds the side seams and end closure panels of the container upon a rotating crossbar mandrel which eliminates any misalignment during the sealing process. A substantially rigid conveyor transport carries a plurality of the carton blanks through pre-form, filler, and end closure work stations, and includes plural anvils for the ultrasonic welding process. An ejector mechanism is additionally provided which ejects the filled carton blanks from the rigid conveyor along a dual direction path, thereby eliminating the possibility of creasing or puncturing the filled and sealed container. The apparatus of the present invention additionally accommodates the production of differing size containers with only minor adjustments.
