Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
230 words
A container comprising an outer casing having a base-side opening and a front-side opening and not deformable by rail pressure, an inner container fitted in said outer casing for containing liquid therein and having a nozzle at the front end thereof, said inner container having a resilient structure portion that it is depressed inwardly by an external pressure applied to the base-side portion thereof but is restored to its original shape when the pressure is removed, a support member which is in engagement with or fitted in said outer casing at the rear of said inner container to hold the inner container in the outer casing, said support member having a pressure portion for compressing the inner container at the base side thereof when a finger push is applied from behind and said support member further having a resilient structure portion for allowing the inner container to restore its original position, and an inner ring between said outer casing and said inner container, one end of said inner ring abutting a ledge formed on the inner container at a location nearer to the nozzle than from the resilient structure portion and the other end thereof abutting the support member, whereby a single finger-push applied from behind the support member allows the inner container to discharge one drop of liquid out of its content through the front end of the nozzle.
