Abstract
A cotton applicator is disclosed as including a support rod and a cotton pledget disposed on an end thereof with the pledget having forward and rearward sections; the rearward section is about twice the diameter of the forward section with an annular shoulder therebetween whereby the forward section is limited in its penetration into an ear canal by the annular shoulder and the rearward section. The support rod axially extends through the rearward section and partially into the forward section whereby adequate support is provided for each section.
Claims1
A cotton applicator for use in a cavity defined by an ear and the like comprising
- a unitary rod being disposed on a longitudinal axis so as to be linear along its entire length,
- a pledget of cotton on said supporting end adapted for unitary rotation therewith,
- said pledget of cotton including a forward generally cylindrical section of uniform diameter throughout its length, a generally bulbous rearward section having a major diameter approximately twice as large as the diameter of the cylindrical section and an annular wall extending transversely between the cylindrical and bulbous sections
- said supporting end of said rod extending axially through the bulbous section and terminating at the approximate mid-point of the cylindrical section to enhance support for the cylindrical section during rotary use of the applicator about said longitudinal axis and thereby avoid separation of the cynlindrical section from the bulbous section,
- said bulbous section tapering decreasingly from the major diameter of said annular wall to the diameter of said cylindrical section rearwardly thereof,
- said annular wall having inner and outer diameters the same as the diameter of said cylindrical section and the major diameter of said bulbous section, respectively,
- said annular wall engagable with an outside perimeter of the cavity and thereby limit penetration of the cylindrical section into the cavity.
