摘要： A liquid tight rectangular paperboard container (10) is provided with a separate opening tab (17) secured to the top panel (15) thereof which enables the package to be opened to provide a fully open top. In particular, an elongate plastic window (18c) is formed along the front fold line (15a) connecting the top and front panels (15 and 11) of the package, and has ends (18d, 18e) connected to spaced apart arcuate shaped perforated lines (18a, 18b) extending to the rear corners of the top panel. In the construction of the package, the opening tab (17) is first ultrasonically welded to the outside surface of the package blank, and then the window section (18c) is pressed against and welded to the inside surface of the tab. A slit (40) which is formed in the window enables any air trapped between the window and the tab to escape during the welding operation. The package also includes a unique side sealing flap structure, while the particular paper supply roll from which the package is constructed has a unique structure. Also, a unique method of forming the package is disclosed.
摘要翻译：液密的矩形纸板容器（10）设置有固定到其顶板（15）的单独的开口突片（17），其使得包装件能够打开以提供完全敞开的顶部。特别地，沿着连接包装的顶板和前面板（15和11）的前折叠线（15a）形成细长的塑料窗（18c），并且具有连接到间隔开的弧形穿孔的端部（18d，18e）线（18a，18b）延伸到顶板的后角。在包装的构造中，首先将开口接头（17）超声波焊接到包装坯料的外表面，然后将窗部（18c）压靠并焊接到突片的内表面。形成在窗口中的狭缝（40）使得在焊接操作期间能够在窗口和突片之间捕获的任何空气逸出。该包装还包括独特的侧密封翼片结构，而构造包装的特定供纸辊具有独特的结构。另外，公开了形成封装的独特方法。

摘要： The present invention relates to a cardboard notching machine which mainly consists of a body, a transmission group, a roller group, an adjustment group, and a forming group. The roller group is driven by the transmission group so as to feed in cardboards for notching and the forming group has forming cutters for notching cardboards, allowing the notching of cardboard to be performed and completed in one step on the notching machine according to the present invention. Due to the adjustment of gaps between the rollers of the roller group by means of the adjustment group, the forming cutters form notches in a vibrating manner which gives the notches more accurate depth and more smooth surfaces.
摘要翻译：本发明涉及一种主要由主体，传动组，辊组，调节组和成形组成的纸板切割机。辊组由传动组驱动，以便进给纸板以进行切口，成型组具有用于开槽纸板的成形切割器，允许在根据本发明的开槽机上一次执行并完成纸板的切口。由于通过调节组调整辊组之间的间隙，成形切割器以振动的方式形成凹口，这使切口更加精确的深度和更光滑的表面。

摘要： A strip of paperboard material having a thickness of 170 to 600 .mu.m and a multiplicity of fold lines formed widthwise thereof at a predetermined spacing and U-shaped in cross section is caused to travel as reeved around two prefolding rolls, 5 to 30 mm in diameter, from different directions at a contact angle of 40 to 270 degrees to bring the projecting side of the fold lines into contact with the peripheral suface of one of the rolls and the indented side of the fold lines with the peripheral surface of the other roll. This method imparts increased foldability to the fold lines.
摘要翻译：将厚度为170〜600μm的纸板材料条以宽度方向形成有多个预定间隔的折叠线，并且横截面为U形，使其围绕两个预折叠辊进行移动，该折叠辊以5至30mm 直径，从接触角为40〜270度的不同方向，使折线的突出侧与其中一个辊的周边表面和折线的凹入侧与另一个辊的外周表面接触。该方法赋予折叠线增加的折叠性。
