Self-drilling sealed capsule for projecting product to incapacitate attacker and for hypodermic injection, has deformable part, where pressure on part effects increase in pressure in chamber for sliding piston and needle to output side
摘要
<p>The capsule has a piston (4) that is traversed by a hollow needle (5). The hollow needle protrudes from the piston and is provided with a sharp or pointed end (6). A pressure on a deformable part (1) effects an increase in pressure in a chamber for sliding the piston and the needle to an output side of a product until the needle pierces the wall of the capsule for allowing the product to be projected from exterior of the capsule through a conduit provided inside the needle.</p>
