## Abstract

Device for applying at least one active principle, consisting of a material wherein one or several capsules or microcapsules containing the active principle(s) are distributed in a binder having a sponge-like consistency so that the active principle(s) is/are released when pressure is exerted on the material. The device consists of a first part (10) and a second part (12), separated by a tear-off portion (14), the capsule or most of the capsules or microcapsules being located in the first part close to the tear-off portion, the first part being detached from the second part by tearing the tear-off portion so as to obtain, at the breakage interface, a surface for applying the active principle(s) contained in the first part when pressure is exerted thereon.

## Claims

### Claim 1

A device for applying at least one active principle, comprising a material wherein one or several capsules containing the active principle(s) are distributed in a binder having a sponge-like consistency so that the active principle(s) is/are released when pressure is exerted on the said material,
said device comprising a first part and a second part, separated by a tearoff portion, the capsule or most of the capsules being located in said first part close to said tear-off portion, said first part being detached from said second part by tearing said tear-off portion so as to obtain, at the breakage interface, a first surface for applying the active principle(s) contained in the first part when pressure is exerted thereon and a second surface for applying the active principle(s) contained in the second part when pressure is exerted thereon, wherein said tear-off portion is formed by two truncated cones which meet at a tapered joint where breakage results in separation of said first part from said second part.

### Claim 2 (depends on 1)

The device according to claim 1, wherein said tapered joint generates, after breakage, said first and second surfaces for applying the active principle(s).

### Claim 3 (depends on 1)

The device according to claim 1 wherein said first part and said second part are symmetrical about the tapered joint.

### Claim 4 (depends on 1)

The device of claim 1, wherein said tear-off portion contains microcapsules with a diameter of between 50 μm and 1.5 mm.

### Claim 5 (depends on 4)

The device according to claim 4, wherein said microcapsules contain different products which react with one another to form active principle(s) when pressure is exerted on said material.

### Claim 6 (depends on 1)

A method for dispensing a fragrance, comprising
providing the device of claim 1 wherein a fragrance is contained in the capsule(s);
tearing the tear-off portion of the device to obtain a breakage interface having two surfaces for applying the fragrance when a pressure is applied to said microparticles.
