## Abstract

Cartridge for volatile substances in the liquid state, such as insecticides or fragrances, of the type including a tray-shaped container closed on one side with a multilayer film, said multilayer film consisting of at least one internal vapour permeable membrane and one external vapour barrier layer. Directing/assisting means are provided, adapted to direct/assist the removal of just a first portion of the external vapour barrier layer—in the form of notches, weakening lines or strengthening lines—along a desired partition line, for cartridge activation.

## Claims

### Claim 1

A cartridge for liquid volatile substances, the cartridge comprising:
a tray-shaped container defining a cavity configured to contain the liquid volatile substances, the tray-shaped container being closed by a multilayer film consisting of at least one internal vapor permeable membrane and an external vapor barrier layer; and
a directing system and an assisting system configured to respectively direct and assist removal of only a first portion of the external vapor barrier layer, according to a desired partition line, for cartridge activation, said directing system comprising an opening starter of said desired partition line, said assisting system comprising weakening lines positioned at two sides of the desired partition line to assist a tearing action triggered by said opening starter between the weakening lines and along the desired partition line.

### Claim 2 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein said opening starter comprises
a notch formed at one end of said partition line, and
one gripping tab extending outside said first portion in the proximity of said notch.

### Claim 3 (depends on 2)

The cartridge for liquid volatile substances as claimed in claim 2, wherein said notch is a V-notch, and
said opening starter further comprises a straight-notch formed in said vapor barrier layer starting from the V-notch and in the direction of said partition line.

### Claim 4 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein said opening starter comprises
two notches formed at two opposite ends of said partition line, and
two gripping tabs extending outside said first portion in the proximity of said two notches.

### Claim 5 (depends on 4)

The cartridge for liquid volatile substances as claimed in claim 4, wherein said two notches are V-notches, and
said opening starter further comprises a straight-notch formed in said vapor barrier layer starting from at least one of said V-notches and in the direction of said partition line.

### Claim 6 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein said weakening lines consist of two continuous laser-cut lines arranged parallel to the two sides of said partition line and through the entire width of said first portion of the vapor barrier layer.

### Claim 7 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein said weakening lines are obtained by applying additional plastic protective layers, arranged parallel to the two sides of said partition line and through the entire width of said first portion of the vapor barrier layer.

### Claim 8 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein said tray-shaped container comprises two different depth areas, a lesser-depth area of the two different depth areas facing said first portion of the vapor barrier layer.

### Claim 9 (depends on 2)

The cartridge for liquid volatile substances as claimed in claim 2, wherein said tray-shaped container comprises two different depth areas, a lesser-depth area of the two different depth areas facing said first portion of the vapor barrier layer.

### Claim 10 (depends on 3)

The cartridge for liquid volatile substances as claimed in claim 3, wherein said tray-shaped container comprises two different depth areas, a lesser-depth area of the two different depth areas facing said first portion of the vapor barrier layer.

### Claim 11 (depends on 6)

The cartridge for liquid volatile substances as claimed in claim 6, wherein said tray-shaped container comprises two different depth areas, a lesser-depth area of the two different depth areas facing said first portion of the vapor barrier layer.

### Claim 12 (depends on 7)

The cartridge for liquid volatile substances as claimed in claim 7, wherein said tray-shaped container comprises two different depth areas, a lesser-depth area of the two different depth areas facing said first portion of the vapor barrier layer.

### Claim 13 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein, in a normal position of use of the cartridge in which said multilayer film lies in a vertical plane, a portion of said at least one vapor permeable membrane, corresponding to said first portion of the vapor barrier layer, is permanently soaked by said liquid volatile substances for a time of a useful life of said cartridge.

### Claim 14 (depends on 13)

The cartridge for liquid volatile substances as in claim 13, wherein, in said normal position of use of the cartridge, said first portion of the external vapor barrier layer corresponds to a lower portion of said multilayer film.

### Claim 15 (depends on 2)

The cartridge for liquid volatile substances as claimed in claim 2, wherein, in a normal position of use of the cartridge in which said multilayer film lies in a vertical plane, a portion of said at least one vapor permeable membrane, corresponding to said first portion of the vapor barrier layer, is permanently soaked by said liquid volatile substances for a time of a useful life of said cartridge.

### Claim 16 (depends on 3)

The cartridge for liquid volatile substances as claimed in claim 3, wherein, in a normal position of use of the cartridge in which said multilayer film lies in a vertical plane, a portion of said at least one vapor permeable membrane, corresponding to said first portion of the vapor barrier layer, is permanently soaked by said liquid volatile substances for a time of a useful life of said cartridge.

### Claim 17 (depends on 7)

The cartridge for liquid volatile substances as claimed in claim 7, wherein, in a normal position of use of the cartridge in which said multilayer film lies in a vertical plane, a portion of said at least one vapor permeable membrane, corresponding to said first portion of the vapor barrier layer, is permanently soaked by said liquid volatile substances for a time of a useful life of said cartridge.

### Claim 18 (depends on 8)

The cartridge for liquid volatile substances as claimed in claim 8, wherein, in a normal position of use of the cartridge in which said multilayer film lies in a vertical plane, a portion of said at least one vapor permeable membrane, corresponding to said first portion of the vapor barrier layer, is permanently soaked by said liquid volatile substances for a time of a useful life of said cartridge.

### Claim 19 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein the weakening lines are continuous.

### Claim 20 (depends on 1)

The cartridge for liquid volatile substances as claimed in claim 1, wherein the liquid volatile substances are in a liquid state.
