TH44487A - Equipment for the diffusion of volatile materials. - Google Patents

Abstract

DC60 (07/10/42) What is revealed here is a device for the diffusion of vapors, such as pesticides. A platform-like element provides a cavity for the volatile material. A leg structure of one or more platforms extends downwards from the top of the platform to support the cavity in the top of the platform at a certain distance above the heating element. This results in more moderate and uniform heating, i.e., allowing for a longer release period of the volatile material.

Claims (15)

1. A suitable platform for vapor diffusion when heated consists of: an upper platform with a cavity in its upper surface, the vaporizing material placed in the cavity, and supports extending below the upper platform. These supports are constructed and manipulated to fit snugly onto the heating surface while leaving an air gap between the lower part of the cavity and the heating surface of the heater. The supports extend radially outwards, at least partially, over the cavity. 2. The basis of claim 1, whereby the volatile material is selected from a group comprising pesticides, insect repellents, aromatic materials and deodorants. 3. The basis of claim 1 is such that a porous, solid base layer is positioned within the void, and the volatile material saturates the base. 4. The basis of claim 3, whereby the gel mixed with the volatile material is positioned within the cavity. 5. The basis of claim 4 is further comprised of a permeable membrane that extends over the cavity. 6. A stand for claim number 1, the top of which shall be made of heat-resistant metal, plastic, or ceramic. 7. A stand for claim number 1, where the support structure is made of plastic. 8. The vapor diffusion device consists of: a heater with a heating surface and a platform for claim 1, positioned adjacent to the heating surface. 9. Equipment of claim number 8, where the heater is an electrical resistance heater. 10. The stand for claim 1, where the support is constructed from heat-resistant, thermally insulating material. 11. The basis of claim 9 is that the heat-resistant, thermally insulating material is selected from a group comprising cellulose, heat-resistant plastics, and ceramics. 12. The basis of claim 1, whereby the support consists of at least two lateral openings to allow air to flow from the outside of the support into the air gap. 13. The stand of claim 1, where the top of the stand and the supports shall be arranged in two separate sets. 14. The stand of claim 1, where at least one gripping part extends from the stand at the edge a distance sufficient to extend beyond the surface of the heater when the stand is placed on that part in order to dissipate excess heat from the stand into the surrounding air. 15. A platform for claim 5, whereby a permeable membrane shall be selected to limit the release of volatile substances to the desired expansion, thereby slowing the release of volatile substances from the platform.
