Attack-repellent device

In an attack repellent device including a housing for attachment to a user's body or article carried by the user, a dispensing nozzle in said housing for dispensing an attack-repellent chemical, a storage section for holding a supply of an attack-repellent chemical and propellant fluid therefor which can force said chemical under pressure through said dispensing nozzle means, and user operable trigger mechanism operable between dormant and active conditions, the improvement comprising:

• at least one of said nozzle and storage section being mounted for movement relative to the other between a first position where they are relatively spaced apart and a second position where they are in close relation;
• a first spring for urging one of said nozzle and storage sections toward and into said second position;
• a latch for establishing latching engagement with said nozzle and storage sections in said first relatively spaced apart positions against the urging force of said spring;
• and said latch releasing from said latching engagement in response to operation of said trigger to said active condition to permit said spring to position said nozzle and storage section in said close relation and for causing said propellant fluid and attack-repellent chemical to be directed through said nozzle;

• said nozzle means being at least two spaced nozzles having a passageway extending therethrough between a chemical inlet orifice at the inner end thereof and a discharge orifice at the outer end thereof;
• said container-receiving means in said housing holding either one large container or at least smaller containers to contain pressurized fluid and the repellent chemical;
• each container having an attack chemical discharge portion to receive the inner end of one of said nozzles to make communication with the interior thereof when the nozzle and container are brought together;
• said housing having a container insertion recess and a removable cover for the recess for permitting the insertion into or removal from said recess of a selected one or more of said containers from the housing;
• and
• means responsive to the operation of said user operable release means to said active condition for bringing the inner end of one of said nozzles into communication with the interior of said large containers or the interior of each of said smaller containers at the location of said discharge portion thereof for discharging said propellent fluid and attack-repellent chemical through the associated nozzle.

In an attack-repellent device including a hosing for attachment to a user's body or article carried by the user, a dispensing nozzle in said housing for dispensing an attack-repellent chemical, a storage section for holding a supply of an attack-repellent chemical and propellant fluid therefor which on force said chemical under pressure through said dispensing nozzle means, and user operable rigger mechanism operable between dormant and active conditions, the improvement comprising at least one of said nozzle and storage section being mounted for movement relative to the other between a first position where they are relatively spaced apart and a second position where they are in close relation;

• spring means for urging one of said nozzle and storage sections toward and into said second position;
• a latch for establishing latching engagement with said nozzle and storage sections in said first relatively spaced apart positions against the urging force of said spring;
• and said latch releasing from said latching engagement in response to operation of said trigger to said active condition to permit said spring to position said nozzle and storage section in said close relation and for causing said propellant fluid and attack-repellent chemical to be directed through said nozzle;
• and both of said nozzle and storage section being mounted for movement, one toward the other, said spring means including separate springs for respectively urging said nozzle and storage sections together.

In an attack-repellent device including a housing for attachment to a user's body or article carried by the user, a dispensing nozzle in said housing for dispensing an attack-repellent chemical, a storage section for holding a supply of an attack-repellent chemical and propellant fluid therefor which can force said chemical under pressure through said dispensing nozzle means, and user operable trigger mechanism operable between dormant and active conditions, the improvement comprising:
