发明名称 SELF-CLOSING SEALABLE VALVE BAG
摘要 A valve bag (80, 80') is provided having a self-closing valve (92, 92') extending exteriorly outward from a front side panel (82, 82'). The valve (92, 92') includes a valve sleeve (96, 96') and valve tube support members (94, 94', 95, 95'). The valve sleeve (96, 96') and the valve tube support members (94', 95') extend exteriorly from and internally of the valve bag (80, 80'). The internal portion (106, 106') of the valve sleeve seals the valve (92, 92') of the bag subsequent to filling of the bag with material. The valve (92, 92') is then further sealed at the portion of the valve sleeve (96, 96') that extends exteriorly of the front side panel (82, 82').
