发明名称 RECLOSABLE BAG WITH EXPANSION GUSSET
摘要 A reclosable bag (10) for packaging bulk items for retail sale has a body having opposing broad face panels (12, 16) defining a volume therebetween for holding a quantity of contents, an end of the body forming an expandable gusset (20, 62, 82) between the broad face panels, and a reclosable bag closure (30, 150) between the expandable gusset and corresponding edge region of one of the broad face panels. When the closure is opened a bag opening (42) is formed between the expandable gusset and said one of the broad face panels of the bag, to access the bag contents. In one example, the bag has upper and lower expandable gussets (18, 20), while in another the bag has expandable side gussets (62). The closure is readily closed without precise alignment and despite the adjacent gusset.
