Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
170 words
A dispensing container for dispensing a viscous cosmetic product such as toothpaste comprising a container body provided with a resiliently compressible portion including a mouthpiece at one end of said container body, a piston member arranged in said container body at the other end to define a boundary of the interior space of the container, the piston member being movable towards and restrained from movement away from said compressible portion, and valve means comprising a flap having an area of at most 0.8 square centimeters, which is mounted in the mouthpiece by resilient hinge means and which in a closed position substantially fills out the interior cross-section of the mouthpiece, the flap being slightly spaced from the wall defining the interior cross section of the mouthpiece except at the area of mounting and openable by pressure on said resiliently compressible portion of the container and being closable by the resilience of the hinge means, and an abutment protruding into such interior cross-section to support the flap in its closed position.
Claim 2
Dependent Claim
170 words
A dispensing container for dispensing a viscous cosmetic product such as toothpaste comprising a container body provided with a resiliently compressible portion including a mouthpiece at one end of said container body, a piston member arranged in said container body at the other end to define a boundary of the interior space of the container, the piston member being movable towards and restrained from movement away from said compressible portion, and valve means comprising a flap having an area of at most 0.8 square centimeters, which is mounted in the mouthpiece by resilient hinge means and which in a closed position substantially fills out the interior cross-section of the mouthpiece, the flap being slightly spaced from the wall defining the interior cross section of the mouthpiece except at the area of mounting and openable by pressure on said resiliently compressible portion of the container and being closable by the resilience of the hinge means, and an abutment protruding into such interior cross-section to support the flap in its closed position.
