CLOSURE DEVICE FOR STORAGE BAG

摘要

A closure element is used for closing an opening disposed through the flexible sidewall of a storage bag such as those used to store food items. The storage bags provide an internal volume accessible via the opening. The closure element includes a first fastening strip and an interlocking second closure strip. The first and second fastening strips include complementary, engagable first and second closure profiles. To hermetically seal the internal volume, at least a portion of the first or second fastening strip can include a sealant. The sealant can be a displaceable fluid, fluid-like substance, semi-rigid substance, or wax-like substance such as an oil or a gel. When the closure profiles are engaged, the sealant provides an air tight barrier sealing the internal volume.
