Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 232 words
A container and closure therefor comprising a body part, said body part forming a material holding reservoir closed at one end, open at the other end and bounded peripherally by a wall to provide the reservoir with a substantially uniform cross-section throughout its length, said closure including a piston, peripheral sealing means on said piston engaging said reservoir wall in sealing relationship thereto, said sealing means including a resilient lip extending angularly downwardly and outwardly towards the closed end of said reservoir, the outer dimensions of said lip being, when in an uncompressed state, slightly greater than the internal dimensions of said container, said closure having an air bleed hole therethrough and provided with means for closing said hole, said reservoir wall having a pair of diametrically opposed holes therethrough adjacent the upper limit thereof, a handle having a pair of ends detachably secured within said wall holes for carrying said reservoir, said closure including an upstanding peripheral rim provided with diametrically opposed slots alignable with said wall holes to permit attachment of said handle ends without interference from said closure rim, said closure rim provided with a pair of diametrically opposed holes angularly offset substantially 90* from said closure rim slots and engageable with said handle ends when detached from said wall holes to facilitate upward and downward movement of said closure within the container without angular displacement of said closure.
Claim 2
Dependent Claim 232 words
