Abstract
Abstract An insecticide apparatus comprising a substantially tubular housing having an open end and including a chemical exterminating means such as lead arsenate and a resilient flexible guard which must be squeezed to permit insertion into the open end of the tubular housing, and which is positioned over the chemical exterminating means to prevent the chemical exterminating means from being easily removed or improperly accessible either accidentally or intentionally by other than insects. A guardholding lip is also positioned and projects across the portion of the open end to retain the guard in place after release. The guard may be made of any suitable plastic or other material which is flexible and resilient.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
An insecticide apparatus comprising a substantially tubular housing having an open end, a chemical exterminating means positioned adjacent the inner surface of and within said housing, a resilient guard positioned over and covering said chemical exterminating means and within said housing, said guard having an enclosure means including a plurality of openings therein containing said chemical exterminating means and providing insect access to said chemical exterminating means through said guard opening, said guard being of flexible, resilient material and in expanded unstressed condition before insertion into said housing being of a cross-sectional width greater than the diameter of said open end whereby said guard must be contracted to a stressed condition to pass through said open end and be positioned over said chemical exterminating means to protect said chemical exterminating means from being removed from said housing or against animal access.
Claim 2
Dependent Claim
