发明名称 Method of making, opening, filling and sealing a two-compartment pouch
摘要 An envelope-type pouch is divided into two compartments by a divider panel which is disposed between and is sealed to the two side panels of the pouch. The top margin of the divider panel and the top margin of one of the side panels are disposed above the top margin of the other side panel to facilitate opening of the pouch by an automatic packaging machine. Sealing of the upper end of the pouch is effected by first sealing the top margin of the divider panel to the top margin of the one side panel and then by sealing the top margin of the other side panel to the divider.
