Abstract
Abstract A vaporizer for insecticides and other volatile active substances comprising a housing provided with openings and within which housing the active substances are hermetically enclosed. The vaporizer is preferably made of a plastic or other flexible material and may be carried out in various specific embodiments wherein the active substances, which may be toxic, are kept safely out of contact with humans and can be made available for their intended use in controlled and variable amounts. The active substances may be in a spherical or lenticular casing or housing and can be released from outside in a manner to be volatilized for insecticidal or other activity. There is a holder provided for absorption of the volatiles emerging from the casing after the latter is opened by a member actuable externally thereof for cutting the same.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A vaporizer for volatile active substances comprising a casing containing volatile active substances therein, a housing preferably of plastic for the casing and having an upper portion and a lower portion, an absorptive holder in the lower portion of the housing and arranged to absorb volatiles released from the casing, an opener projecting from the holder and supporting the casing, a hollow shaft formed in and as a part of the housing and enclosing the casing, a pushing member above and resting on the casing and attached to the shaft and which, when pushed down into the shaft breaks away from the shaft and acts to depress the casing and causes the opener to pierce the casing, thereby releasing the contents of the casing for absorption by the holder.
