摘要： A collapsible liner for a bulk container made of a flexible material and having seamless top and bottom walls is provided. The liners are formed from a tubular blank folded to form two gusset panels received inwardly of two overlying flat panels. The blank is severed to form triangular portions adjacent opposed ends of the blank and adjacent sides of adjacent triangular portions are connected together to form a pair of generally opposed and generally rectilinear side walls of the liner. The seamless top and bottom walls are stronger than those portions of the liner with seams and are less likely to rupture or leak.
摘要翻译：提供了一种用于由柔性材料制成并具有无缝的顶壁和底壁的散装容器的可折叠衬垫。衬里由折叠的管状坯料形成，以形成从两个上覆的平板内部收容的两个角撑板。坯料被切断以形成邻近坯料的相对端的三角形部分，并且相邻三角形部分的相邻侧面连接在一起以形成衬套的一对大致相对且大致直线的侧壁。无缝的顶壁和底壁比具有接缝的衬垫的那些部分更坚固，并且不太可能破裂或泄漏。

摘要： A method of making flexible and collapsible bulk bags or liners for bulk bags or containers from individual flat panels of material, or tubes of material folded flat, is disclosed. The bags or liners have one or more sidewalls interconnected by at least a bottom wall and preferably also a top wall generally opposed to the bottom wall. The bags are preferably formed by disposing a pair of inner blanks of material with one on top of the other and then heat sealing along a straight line generally bisecting the blanks and thereafter severing the heat seal along its entire length. Next, a pair of outer blanks of material are disposed adjacent the inner blanks with the inner blanks received between the outer blanks. The outer blanks are each heat sealed about their side edges to an adjacent side edge of an inner blank. Once so formed, the inner blanks form a pair of gusseted panels received between the outer and overlying panels. When expanded, this configuration provides four generally rectilinear sidewalls of the bulk bag. To form the bottom wall of the bulk bag, the outer blanks are heat sealed to the adjacent gusseted, inner blanks along canted lines forming a triangular portion integral with each sidewall. When heat sealed in this manner, a generally rectangular bottom wall, integral with the sidewalls, is formed. A top wall may be formed in a similar manner or separately attached to the bag.
摘要翻译：公开了一种从单独的材料平板或折叠平坦的材料管制造用于散装袋或容器的柔性和可折叠散装袋或衬垫的方法。袋或衬里具有通过至少底壁和优选地也与底壁大致相对的顶壁互连的一个或多个侧壁。袋优选通过将一对材料的内部坯料放置在另一个的顶部上，然后沿着通常将坯料平分的直线热封，然后沿着其整个长度切断热封而形成。接下来，一对材料的外部坯件设置成与内部坯件相邻，而内部坯料被容纳在外部坯件之间。外部坯料各自围绕它们的侧边缘热密封到内部坯件的相邻侧边缘。一旦这样形成，内部坯件形成一对接收在外部和上部面板之间的角撑板。当扩展时，该配置提供了散装袋的四个大致直线的侧壁。为了形成散装袋的底壁，外部坯料沿着斜线热封到相邻的角撑板的内部坯料上，形成与每个侧壁成一体的三角形部分。当以这种方式热密封时，形成与侧壁成一体的大致矩形的底壁。顶壁可以以类似的方式形成或者分开地附接到袋子上。

摘要： A generally cubical collapsible bag with six generally rectangular walls of a flexible plastic material. A spout with an enclosed end is attached to the bag by a continuous heat seal. The spout communicates with the interior of the bag through an opening encircled by the heat seal. Preferably the spout is attached to the inside of the bag and passes through the opening and extends exteriorly of the bag.

摘要： A collapsible bulk bag which when filled with material has a generally cubical configuration with a pair of end walls and rectangular sidewalls extending between them with all of the walls being of a flexible material. Bowing and bulging of the sidewalls from a planar configuration is retarded and restrained by loops of cord operably connected with the sidewalls. Preferably the loops of cord having portions inside the bag extending obliquely between adjacent sidewalls when the bag is filled. Methods of making the bag with the loops of cord are also disclosed.

摘要： A reinforced collapsible bag and method of making it from blanks of a flexible woven material which are cut from an elongate web substantially without wasting any material between adjacent blanks with pairs of reinforced strips extending along the side edges and through the central portion of the sides and top and bottom of the bag, thereby reinforcing the bottom, top, sides and corners of the bag. Each blank has a circumferentially continuous central portion and four isosceles triangular portions at each end of the blank. Adjacent sides of adjacent triangular portions are connected together to provide, when the bag is expanded or filled, generally square ends which are interconnected by generally rectangular side walls. Lifting straps can be attached to the reinforced strips along the side edges of the bag. An access opening is provided in an end of the bag by terminating the connections of its triangular portions short of their apexes. Preferably, a spout is received in the access opening and connected to the triangular portions.
