发明名称 Bulk container with glued bottom
摘要 A flexible bulk container having a glued bottom portion manufactured by a process comprising the following steps: A sidewall blank having a hollow tubular configuration is suspended in the shape of the desired container and is positioned over a bottom wall located on a raised work area. Adhesive or glue is applied to either the bottom wall and/or the sidewall in areas where the sidewall blank will be permanently in contact with the bottom wall. The sidewall blank is lowered into contact with the bottom wall such that a lower portion of the sidewall blank is located below the work area and an upper portion is located above the work area. The sidewall blank is secured to the bottom wall by folding the upper portion of the sidewall blank over the bottom wall thereby containing the adhesive or glue.
