Abstract

Abstract A container having a nozzle for dispensing eyedrops is provided with means defining an annular surface surrounding the nozzle and extending at least such distance that an extremity of said surface is approximately coplanar with the free end of the nozzle in a plane perpendicular to the axis of the nozzle. An annular space is left between the means defining the annular surface and the nozzle. In this manner, the container is provided with an appearance which is that of a blunt object from the perspective of a user during use of the container to dispense the eyedrops, while the provision of an annular space prevents interference with the drop dispensing function of the nozzle and may also permit use of a standard cap over the nozzle.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 219 words
A receptacle for containing and dispensing drop-wise a liquid composition for application to the eye of the user, comprising a hollow body for containing the liquid, means extending from and communicating directly with the uppermost portion of said hollow body for dispensing the liquid drop-wise from the container in the inverted position thereof, and bumper means defining inner cylindrical surface means surrounding said dispensing means and extending at least such distance that an extremity of said surrounding means is approximately coplanar with the outer end of said dispensing means in a plane perpendicular to the axis thereof, the upper portion of said bumper means being rounded in elevational cross-section and further defining an outer domeshaped surface extending from the outer end of said dispensing means and diverging away from the eye of the uSer when said receptacle is in the inverted position with said dispensing means above the eye of the user, said bumper means being dimensioned for preventing insertion thereof past the outermost portions of the users eyelids so as to constitute said bumper means during use of the receptacle to dispense the liquid composition dropwise into an eye of the user as a blunt object before the eye of the user and as means for preventing contact between the eye of the user and said dispensing means.
Claim 2
Dependent Claim 219 words
A receptacle for containing and dispensing drop-wise a liquid composition for application to the eye of the user, comprising a hollow body for containing the liquid, means extending from and communicating directly with the uppermost portion of said hollow body for dispensing the liquid drop-wise from the container in the inverted position thereof, and bumper means defining inner cylindrical surface means surrounding said dispensing means and extending at least such distance that an extremity of said surrounding means is approximately coplanar with the outer end of said dispensing means in a plane perpendicular to the axis thereof, the upper portion of said bumper means being rounded in elevational cross-section and further defining an outer domeshaped surface extending from the outer end of said dispensing means and diverging away from the eye of the uSer when said receptacle is in the inverted position with said dispensing means above the eye of the user, said bumper means being dimensioned for preventing insertion thereof past the outermost portions of the users eyelids so as to constitute said bumper means during use of the receptacle to dispense the liquid composition dropwise into an eye of the user as a blunt object before the eye of the user and as means for preventing contact between the eye of the user and said dispensing means.
Claim 3
Dependent Claim 86 words
A receptacle according to claim 1, further comprising said bumper means defining an annular space surrounding said dispensing means, the upper portion of said bumper means being rounded in elevational cross section a hollow neck joining said dispensing means to the hollow body, a screw thread on the external surface of the neck and a cap having an internal screw thread to mate with the thread on the neck, the cap being dimensioned to fit in the annular space and being screwed down onto the neck.
