  • Patent number: 4209096
    Abstract: A blister type container of the type generally intended for a single dispensing use, the container having a reclosable, securable lid which reinforces the container against accidental dispensing of the contents both before and after an initial use. The invention comprises a blister container including a nozzle portion having a frangible segment for forming a nozzle opening and a lid, wherein the nozzle portion is surrounded by an integrally formed flange member sealingly engaged to a flexible backing strip and having (1) a transverse weakened segment aligned with the frangible segment of the nozzle portion for forming a finger tab for facilitating the breaking of the frangible nozzle segment; and (2) an arcuate cross section in the vicinity of the transverse, weakened segment which cooperates with the flexible backing strip to exert a sealing force on the lid when the lid is placed over the nozzle opening.
