Fire extinguisher unit

A collapsible holder for supporting on a vertical surface a fire extinguisher having a generally cylindrical construction with a diameter DC, comprising:

• a) an elongate, generally-planar holder base having an upper end and a lower end, and a tongue fixed to and extending from each end;
• b) means for mounting said holder base on the vertical surface;
• c) a first clamp removably fixed to and extending transverse to said holder base, said first clamp including:
• i) a clamp base;
• ii) a groove formed in said clamp base, said groove constructed and arranged to cooperatively engage the top tongue of said holder base;
• and,
• iii) a pair of arcuate arms fixed to and extending outwardly transverse to said clamp base, said arcuate arms defining a first socket formed in between said arms, said first socket having a diameter D1 less than DC, an open bottom, an open top, and a peripheral slit having a width W1 that is smaller than D1;
• d) a second clamp removably fixed to and extending transverse to said holder base, said second clamp including:
• i) a clamp base;
• ii) a groove formed in said clamp base, said groove constructed and arranged to cooperatively engage the bottom tongue of said holder base;
• and,
• iii) a second pair of arcuate arms fixed to and extending outwardly transverse to said clamp base, said arcuate arms defining a second socket formed in between said arms, said second socket having a diameter D2 that is less than DC and an open top, and;
• iv) a flange fixed to at least one of said arms and extending radially inwardly, said flange defining at least a partial bottom of said second socket;
• wherein said holder releasably supports the fire-extinguisher on the vertical surface.

A fire extinguisher, comprising:

• a) a housing comprising a cylindrical canister having a diameter DC, a closed bottom end, and a reduced-diameter neck at the top end;
• b) a flexible internal pouch containing fire suppressant;
• c) means for pressurizing said pouch;
• d) a valve connected to said pouch, said valve being operable between open and closed positions for regulating the flow of fire suppressant from said pouch;
• e) a spray head connected to said valve, said spray head actuating said valve between the closed and open positions and directing the flow of fire suppressant from said pouch;
• f) a transparent cap covering said spray head and releasably connected to the neck of said canister;
• and,
• g) a layer of film enveloping said cap and at least a portion of said canister;
• wherein said canister can be grasped with one hand, and said spray head can be linearly depressed with the index finger of the same hand grasping said canister;
• and,
• wherein said cap can not be removed from said canister without permanently damaging said film layer.
