Hand-held self defense device

A self-defense device for holding in a hand of a user, the self-defense device comprising:

• (a) a chamber including:
• (i) a rigid outer wall, and
• (ii) a flexible outer wall attached to said rigid outer wall, said rigid wall enclosing a portion of said flexible wall, and
• (b) an ejection assembly including:
• (i) a tube extending through said chamber, and having a first end for fluidly communicating therewith, and
• (ii) a nozzle attached to a second end of said tube and communicating with an environment external to the device,
• said chamber being designed and configured such that external pressure exerted upon said flexible outer wall increases an internal pressure of said chamber, such that said fluid is forcefully and directedly ejected from the device through said tube and out said nozzle.

A self-defense device for holding in a hand of a user, the self-defense device comprising:

• (a) a chamber for storing a noxious fluid;
• (b) a handle for holding the device in a firing position by the hand of the user, said handle encompassing said chamber, said handle including:
• (i) a rigid wall, and
• (ii) a flexible wall attached to said rigid wall, and
• (c) an ejection assembly disposed within the device and communicating with an environment through an outer wall of the device, said ejection assembly including:
• (i) a tube extending through said chamber, and having a first end for fluidly communicating therewith;
• (ii) a nozzle attached to a second end of said tube,
• wherein said rigid wall forms a portion of an orthogonally prismatic form rounded to conform to a palm of the hand, and said flexible wall forms an opposing portion of said form, and
• wherein an external pressure exerted upon said flexible wall of said handle increases an internal pressure of said chamber, such that said fluid is forcefully ejected from the device through said tube and out said nozzle.

A self-defense device for holding in a hand of a user, the self-defense device comprising:

• (a) a chamber for storing a noxious fluid;
• (b) a handle for holding the device in a firing position by the hand of the user, said handle encompassing said chamber, said handle including:
• (i) a rigid wall, and
• (ii) a flexible wall attached to said rigid wall, and
• (c) an ejection assembly disposed within the device and communicating with an environment through an outer wall of the device, said ejection assembly including:
• (i) a tube extending through said chamber, and having a first end for fluidly communicating therewith;
• (ii) a nozzle attached to a second end of said tube,
• wherein an external pressure exerted upon said flexible wall of said handle increases an internal pressure within an entirety of said chamber, such that said fluid is forcefully ejected from the device through said tube and out said nozzle.

A method of self defense using a self-defense device held in a hand of a user, the method comprising the following steps:

• (a) providing the self-defense device, the device including:
• (i) a chamber including:
• (1) a rigid outer wall section, and
• (2) a flexible outer wall section attached to said rigid outer wall section;
• (ii) an ejection assembly fixed inside and communicating through said outer wall of said chamber, said ejection assembly including:
• (1) a tube extending through said chamber, and fluidly communicating therewith;
• (2) a nozzle attached to an end of said tube and communicating with an environment, and
• (iii) a fluid for filling said chamber;
• (b) grasping said self-defense device with said rigid chamber section butted against a palm of the hand and a base of a thumb of the hand, and with said flexible chamber section held within at least one finger;
• (c) aiming said device at a target, and
• (d) squeezing said flexible wall section of said device with said at least one finger, thereby increasing an internal pressure within an entirety of said chamber, such that said fluid is forcefully ejected from the device through said tube and out said nozzle.
