Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
198 words
A disposable container and lid, having both a releasable seal and a non-releasable seal, comprising (a) a container having a filling opening at one end and a sealing ring about its outer periphery proximate said one end, said container further having an outer surface extending away from said one end; a container locking projection extending from said outer surface; and an outwardly increasing ramp face extending from said outer surface, said ramp face terminating in a retaining projection; and (b) a lid sized for closure of said filling opening, said lid having a downwardly projecting inner edge surface, said inner edge surface having an inner encircling counter face engageable against said sealing ring; said inner edge surface also having a lid locking projection extending inwardly from said surface and engageable in releasable locking engagement against said container locking projection; said inner edge surface terminating in an inwardly directed detent engageable in non-releasing locking engagement against said retaining projection, whereby said sealing ring is partially compressed when said lid locking projection is in locking engagement with said container locking projection, and said sealing ring is further partially compressed when said detent is in locking engagement against said retaining projection.
Claim 2
Dependent Claim
198 words
A disposable container and lid, having both a releasable seal and a non-releasable seal, comprising (a) a container having a filling opening at one end and a sealing ring about its outer periphery proximate said one end, said container further having an outer surface extending away from said one end; a container locking projection extending from said outer surface; and an outwardly increasing ramp face extending from said outer surface, said ramp face terminating in a retaining projection; and (b) a lid sized for closure of said filling opening, said lid having a downwardly projecting inner edge surface, said inner edge surface having an inner encircling counter face engageable against said sealing ring; said inner edge surface also having a lid locking projection extending inwardly from said surface and engageable in releasable locking engagement against said container locking projection; said inner edge surface terminating in an inwardly directed detent engageable in non-releasing locking engagement against said retaining projection, whereby said sealing ring is partially compressed when said lid locking projection is in locking engagement with said container locking projection, and said sealing ring is further partially compressed when said detent is in locking engagement against said retaining projection.
