Airtight magnetic applicator system

A container comprising:

• (A) a longitudinally extending reservoir for a flowable material, said reservoir having a closed end, an open end and a magnetically-transmissive sidewall;
• (B) a removable cover for closing said reservoir open end, said reservoir and said cover cooperatively defining an airtight enclosure for the flowable material;
• (C) an exterior magnet;
• (D) means for maintaining said exterior magnet on the exterior of said reservoir sidewall and for moving said exterior magnet between a first position adjacent said reservoir closed end and a second position adjacent said reservoir open end;
• (E) a longitudinally extending applicator defining
• (i) a head for transferring the flowable material from the reservoir interior through said reservoir open end,
• (ii) a base carrying an interior magnet responsive to said exterior magnet for longitudinal movement therewith, and
• (iii) a stem connecting said head and said base in an offset relationship such that, when said head is substantially aligned with a central longitudinal axis of said reservoir, said interior magnet is closely adjacent the interior of said reservoir sidewall and magnetically coupled with said exterior magnet for longitudinal movement therewith as a unit;
• and
• (F) means for maintaining said applicator head in substantial alignment with the central longitudinal axis of said reservoir.

A cosmetic container comprising:

• (A) a longitudinally extending reservoir for a flowable cosmetic, said reservoir having a closed end, an open end and a magnetically-transmissive sidewall;
• (B) a removable cover for closing said reservoir open end, said reservoir and said cover cooperatively defining an airtight enclosure for the cosmetic;
• (C) an exterior magnet;
• (D) means for maintaining said exterior magnet on the exterior of said reservoir sidewall and for moving said exterior magnet between a first position adjacent said reservoir closed end and a second position adjacent said reservoir open end;
• (E) a longitudinally extending applicator defining:
• (i) a head for transferring the cosmetic from the reservoir interior through said reservoir open end,
• (ii) a base carrying an interior magnet responsive to said exterior magnet for longitudinal movement therewith, and
• (iii) a stem connecting said head and said base such that, when said head is substantially aligned with a central longitudinal axis of said reservoir, said interior magnet is closely adjacent the interior of said reservoir sidewall and magnetically coupled with said exterior magnet for longitudinal movement therewith as a unit;
• (F) means for maintaining said applicator head in substantial alignment with the central longitudinal axis of said reservoir;
• and
• (G) a stationary flow controller extending through said reservoir open end in fluidtight relationship.

A cosmetic container comprising:

• (A) a longitudinally extending reservoir for a flowable cosmetic, said reservoir having a closed end, an open end and a magnetically-transmissive sidewall;
• (B) a removable cover for closing said reservoir open end, said reservoir and said cover cooperatively defining an airtight enclosure for the cosmetic;
• (C) an exterior magnet;
• (D) means for maintaining said exterior magnet on the exterior of said reservoir sidewall and for moving said exterior magnet between a first position adjacent said reservoir closed end and a second position adjacent said reservoir open end;
• (E) a longitudinally extending applicator defining:
• (i) a head for transferring the cosmetic from the reservoir interior through said reservoir open end,
• (ii) a base carrying an interior magnet responsive to said exterior magnet for longitudinal movement therewith, and
• (iii) a stem connecting said head and said base such that, when said head is substantially aligned with a central longitudinal axis of said reservoir, said interior magnet is closely adjacent the interior of said reservoir sidewall and magnetically coupled with said exterior magnet for longitudinal movement therewith as a unit;
• and
• (F) means for maintaining said applicator head in substantial alignment with the central longitudinal axis of said reservoir;
• said container being characterized in that
• said reservoir is a hollow cylinder of extruded glass having a closed bottom and an open top, and said reservoir sidewall is of constant thickness below said open top;
• said alignment maintaining means is substantially disposed within said reservoir open top and maintains said applicator head in gaseous communication with a volatile solvent in the cosmetic;
• and
• said container additionally includes:
• (i) means for applying the cosmetic to said applicator head as said applicator head moves upwardly through said reservoir open top,
• (ii) means for sealing said reservoir open top about said applicator while said applicator head is outside of said reservoir, thereby to preclude atmospheric exposure of the cosmetic within said reservoir, said sealing means sealing said reservoir open top about said applicator head, and
• (iii) means for maintaining said applicator head in fluid communication with the cosmetic while said cover closes said reservoir open top.

A cosmetic container comprising:

• (A) a longitudinally extending reservoir for a flowable cosmetic, said reservoir having a closed end, an open end and a magnetically-transmissive sidewall;
• (B) a removable cover for closing said reservoir open end, said reservoir and said cover cooperatively defining an airtight enclosure for the cosmetic;
• (C) an exterior magnet;
• (D) means for maintaining said exterior magnet on the exterior of said reservoir sidewall and for moving said exterior magnet between a first position adjacent said reservoir closed end and a second position adjacent said reservoir open end;
• (E) a longitudinally extending applicator defining:
• (i) a head for transferring the cosmetic from the reservoir interior through said reservoir open end,
• (ii) a base carrying an interior magnet responsive to said exterior magnet for longitudinal movement therewith, and
• (iii) a stem connecting said head and said base such that, when said head is substantially aligned with a central longitudinal axis of said reservoir, said interior magnet is closely adjacent the interior of said reservoir sidewall and magnetically coupled with said exterior magnet for longitudinal movement therewith as a unit;
• (F) means for maintaining said applicator head in substantial alignment with the central longitudinal axis of said reservoir;
• (G) a stationary flow controller, the exterior of said flow controller extending through said reservoir open end in fluidtight relationship therewith, the interior of said flow controller defining a central flow channel having a fluidtight sidewall and including flow restricting means to limit the flow of cosmetic from said reservoir into said central flow channel;
• and
• (H) a ferrule on said applicator intermediate said stem and head thereof, said ferrule being configured and dimensioned to fit snugly into said central flow channel for reciprocating sliding movement relative thereto, said ferrule being operative, cooperatively with said central flow channel, (i) to preclude cosmetic flow from said reservoir into said central flow channel when said applicator head extends outwardly from said central flow channel, (ii) to limit cosmetic flow from said reservoir into said central flow channel when said applicator head is totally within said central flow channel, and (iii) to pump cosmetic from said reservoir into said central flow channel and onto said applicator head as said applicator head is being extended outwardly from said central flow channel.
