## Abstract

A device for evaporating volatile substances including a solid body impregnated with volatile substances and a support for the solid body. The solid body includes a protrusion defining on the inside thereof a housing and the solid body includes a hole, inside of which the protrusion is placed, such that the device further includes a container to house a liquid which impregnates the solid body with volatile substances. The device allows the solid body to be correctly held in the support during the entire useful life thereof. Furthermore, due to the presence of the container with liquid, the user may know if the device is still evaporating the volatile substances correctly or if it must be replaced.

## Claims

### Claim 1

A device for evaporating volatile substances comprising:
a solid body configured to be impregnated with said volatile substances;
a support for said solid body, said support including a protrusion defining on the inside thereof a housing;
said solid body comprising a hole, inside of which said protrusion is placed; and
a container configured to house a liquid which impregnates said solid body with said volatile substances.

### Claim 2 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein the container is placed inside said housing through the hole of the solid body.

### Claim 3 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein said container comprises a flange which is placed on an outer surface of the solid body.

### Claim 4 (depends on 3)

The device for evaporating volatile substances according to claim 3, wherein said flange is placed on the solid body around the hole thereof.

### Claim 5 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein said container contains said liquid and said container comprises a semi-permeable membrane which covers said liquid.

### Claim 6 (depends on 5)

The device for evaporating volatile substances according to claim 5, wherein said semi-permeable membrane is covered by a removable protective film.

### Claim 7 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein said protrusion of the support has a tubular shape.

### Claim 8 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein said solid body is disc-shaped.

### Claim 9 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein said solid body comprises a polyethylene vinyl acetate copolymer impregnated with perfume.

### Claim 10 (depends on 1)

The device for evaporating volatile substances according to claim 1, wherein the support has a concave shape to contain the solid body.
