A BLOCK OR SHAPED BODY OF A MATERIAL CONTAINING AT LEAST ONE ACTIVE, FOR INSTANCE AN INSECTICIDAL, SUBSTANCE WHICH IT GRADUALLY RELEASES, E.G. IN VAPOR FORM, TO THE MEDIUM SURROUNDING THE BODY, E.G. INTO THE SURROUNDING AIR, WHICH BLOCK HAS AT LEAST ONE, PREFERABLY CENTRAL, BORE; AND 2. THE HOLDER DEVICE FOR THE BODY, HAVING TWO CENTERING MEANS WHICH PROJECT FROM BOTH ENDS INTO THE BORE OF THE BODY, AND WHEREIN PASSAGES ARE PROVIDED IN THE HOLDER DEVICE AND ASSOCIATED WITH THE SAID CENTERING MEANS, WHEREBY FRESH SUPPLIES OF THE SURROUNDING MEDIUM CAN ENTER THE CENTRAL BORE AT ONE AND CAN LEAVE THE BORE AT THE OTHER END LADEN WITH FLUID, E.G. GASEOUS PARTICLES OF THE ACTIVE SUBSTANCE ESCAPING FROM THE WALLS OF THE BORE, WHILE ALL THE TIME FLUID PARTICLES OF THE ACTIVE SUBSTANCE ARE ALSO RELEASED FROM THE OUTER SURFACE OF THE BLOCK DIRECTLY INTO THE MEDIUM, E.G.

Total Claims: 16
Claim 1
Independent Claim
179 words
A holder device comprising: a. a carrier disc; b. mandrel-shaped centering means mounted on said carrier disc; said mandrel-shaped centering means being provided with ribs extending parallel to the control axis of said disc, and leaving spaces between them; c. a plurality of spacing means above said carrier disc, and of less height than said mandrel-shaped centering means and associated with the letter in such a way as to leave spaces therebetween, said spaces being in free communication with each other and with the spaces between said ribs as well as with the space surrounding said holder device; d. second centering means substantially aligned with said mandrel-shaped centering means, and being at a greater distance than the far end of the latter centering means from said carrier disc, said second centering means being provided with passage means for placing the space surrounding said holder device in free communication with the spaces between said ribs; and e. fastening means for holding said second centering means in a permanent manner at a determined distance in alignment with said mandrel-shaped centering means.
Claim 2
Dependent Claim
179 words
A holder device comprising: a. a carrier disc; b. mandrel-shaped centering means mounted on said carrier disc; said mandrel-shaped centering means being provided with ribs extending parallel to the control axis of said disc, and leaving spaces between them; c. a plurality of spacing means above said carrier disc, and of less height than said mandrel-shaped centering means and associated with the letter in such a way as to leave spaces therebetween, said spaces being in free communication with each other and with the spaces between said ribs as well as with the space surrounding said holder device; d. second centering means substantially aligned with said mandrel-shaped centering means, and being at a greater distance than the far end of the latter centering means from said carrier disc, said second centering means being provided with passage means for placing the space surrounding said holder device in free communication with the spaces between said ribs; and e. fastening means for holding said second centering means in a permanent manner at a determined distance in alignment with said mandrel-shaped centering means.
Claim 3
Dependent Claim
