Claim 1
Independent Claim
246 words
A contact lens disinfector unit of the type designated to receive a lens case having a pair of contact lenses immersed within a disinfecting solution disposed within said case, wherein said disinfector unit is adapted to heat said disinfecting solution to an elevated temperature thereby to asepticize said lenses, said disinfector unit comprising: a housing having an open end wall and track means disposed internally of said housing; electrical resistent heating means carried within said housing and including an electrically heated heating block having a generally planar upper surface; and drawer means slidably mounted with respect to the track means on the interior of said housing and received within said open end wall, said drawer means including a generally planar section having through aperture formed therein and an upstanding panel on the free end of said drawer means said drawer means being movable between an extended position wherein said aperture generally planar section projects from said housing and said through aperture is disposed for receiving a lens case, and a retracted position, wherein said planar section is received within said housing with said through aperture being superposed of said planar upper surface of the heating block, a lens case disposed in said aperture with the base portion of said lens case exposed for engagement with said heater block upper surface, and said up-standing panel being sized such that when drawer means is in the retracted position, said panel will close the end wall of said housing.

A contact lens disinfector unit of the type designated to receive a lens case having a pair of contact lenses immersed within a disinfecting solution disposed within said case, wherein said disinfector unit is adapted to heat said disinfecting solution to an elevated temperature thereby to asepticize said lenses, said disinfector unit comprising: a housing having an open end wall and track means disposed internally of said housing; electrical resistent heating means carried within said housing and including an electrically heated heating block having a generally planar upper surface; and drawer means slidably mounted with respect to the track means on the interior of said housing and received within said open end wall, said drawer means including a generally planar section having through aperture formed therein and an upstanding panel on the free end of said drawer means said drawer means being movable between an extended position wherein said aperture generally planar section projects from said housing and said through aperture is disposed for receiving a lens case, and a retracted position, wherein said planar section is received within said housing with said through aperture being superposed of said planar upper surface of the heating block, a lens case disposed in said aperture with the base portion of said lens case exposed for engagement with said heater block upper surface, and said up-standing panel being sized such that when drawer means is in the retracted position, said panel will close the end wall of said housing.
Claim 3
Dependent Claim
108 words
A contact lens disinfector unit according to claim 1, wherein said drawer means further includes a second up-standing panel disposed on the opposite side of said lens case receiving through aperture from said first mentioned panel, said second panel being disposed within said housing and of a larger dimension than the opening in said open end wall, thereby providing an abutment stop against said end wall when said drawer means is in the extended position, said panel also being of sufficient size to preclude contact with said electrical resistance heater means through the open end wall of said housing when said drawer means is in the extended position.
Claim 4
Dependent Claim
66 words
A contact lens disinfector unit as defined in claim 1 wherein said housing includes a pair of spaced apart side walls, one of said side walls including a pair of spaced apart detents, and wherein said drawer means includes a spring member arranged to engage said detents for releasably locking said drawer means when fully displaced from said housing and when fully disposed within said housing.
