Abstract

Abstract A disposable trap for small animals, such as mice or similar rodents, in which a pair of co-axially slideable, interfitting plastic members, namely a hollow plunger and an outer housing therefor, are biased axially towards one another by means of an axially imposed external force supplied by an elastic band, or the like, operational to move the two members toward each other. The plunger is substantially enclosed on all sides except for an animal entrance to its hollow interior and the outer housing is fully enclosed except for one end into which the plunger co-extensively fits. When the two members are axially collapsed so that the outer housing surrounds the plunger, the animal entrance is closed off to entrap an animal within the interior of the plunger. A flexible cantilever type trigger plate extends from one end of the outer housing into the trapping chamber of the plunger and suitable detent means are provided to maintain such members in their separated or extended condition. When the animal enters the trapping chamber and releases the detent means by depressing the trigger plate, the plunger is moved rapidly into the outer housing which thereupon blocks off the animal entrance, preventing escape. One end wall of the plunger optionally is removable to afford reuse of the trap, if desired.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 224 words
A trap for the live entrapment of small animals, such as mice, comprising: a pair of co-axially interfitting hollow members, namely, a hollow plunger member and a hollow housing member; said plunger member being walled on all sides to provide an internal entrapment chamber substantially enclosed except for an animal entrance opening through one side thereof; said housing member being enclosed on all sides except for one open end through which said plunger member is removably received; said members having mating cross-sectional configurations whereby said plunger member fits closely within the interior of said housing member for co-axial sliding movement therealong and whereby said animal entrance is closed by an opposing wall of said housing member as said plunger member moves into said housing member; thrust imposing means engaging the exterior of said two members and operable to move said plunger member rapidly into said housing member, one-piece trigger means comprising an elongated member mounted to extend between the closed end of said housing member and the interior of said entrapment chamber; and detent means cooperating with said trigger means and plunger member to releasably hold the latter in position for thrust imposed movement into said housing member when released from said detent means, said plunger member when in said position having said animal entrance opening therein accessibly located outwardly of said housing member.
Claim 2
Dependent Claim 224 words
A trap for the live entrapment of small animals, such as mice, comprising: a pair of co-axially interfitting hollow members, namely, a hollow plunger member and a hollow housing member; said plunger member being walled on all sides to provide an internal entrapment chamber substantially enclosed except for an animal entrance opening through one side thereof; said housing member being enclosed on all sides except for one open end through which said plunger member is removably received; said members having mating cross-sectional configurations whereby said plunger member fits closely within the interior of said housing member for co-axial sliding movement therealong and whereby said animal entrance is closed by an opposing wall of said housing member as said plunger member moves into said housing member; thrust imposing means engaging the exterior of said two members and operable to move said plunger member rapidly into said housing member, one-piece trigger means comprising an elongated member mounted to extend between the closed end of said housing member and the interior of said entrapment chamber; and detent means cooperating with said trigger means and plunger member to releasably hold the latter in position for thrust imposed movement into said housing member when released from said detent means, said plunger member when in said position having said animal entrance opening therein accessibly located outwardly of said housing member.
Claim 3
Dependent Claim 42 words
The combination of claim 1, wherein said plunger member is formed with one open end, and cap means removably mounted over said open end and held in place thereat by said thrust imposing means to provide selected access to said entrapment chamber.
Claim 4
Dependent Claim 62 words
The combination of claim 1, wherein said trigger means comprises a flexible, cantilever mounted blade, and means connecting said blade to an interior end wall of said housing member in position to extend through an opening formed in an opposing end wall of said plunger member whereby the free end of said blade is accessible to an animal within said entrapment chamber.
Claim 5
Dependent Claim 53 words
The combination of claim 3, wherein said detent means operatively engages said opposing end wall of said plunger member within the interior of said housing member, said detent means being formed to slideably disengage said opposing end wall and pass through said opening therein when said blade is depressed within said entrapment chamber.
Claim 6
Dependent Claim 22 words
The combination of claim 1, wherein said thrust imposing means comprises an elastic member tensioned about the exterior of said two members.
