Problems solved by technology

[0006] In addition, semi-permeable barriers have a smaller absorption capacity, which results in a lower diffusion rate of volatile substances during the activation phase of the semi-permeable barrier

Embodiment Construction

[0027] Such as figure 1 As shown, the device for diffusing volatile substances (for example, volatile aromatic substances or insecticides) includes a container 1, a porous diffuser 2, and a protective sheet 3, the container holds the material with the volatile substances, the the porous diffuser is impregnated with said material having volatile substances, and this protective sheet is removed before first use of the diffuser device,

[0028] Furthermore, the diffusion device according to the invention also comprises a barrier layer 4 equipped with windows 41 , wherein said barrier layer 4 is bonded to the container 1 and placed between the porous diffuser 2 and the protective sheet 3 .

[0029] The window 41 is cut into the barrier layer 4 and defines a frame 42 in the barrier layer 4 . That is, before removing the protective sheet 3, the barrier layer 4 has a cut line separating the window 41 from the frame 42, wherein the window 41 is covered by a part of the barrier layer ...

Abstract

The invention discloses a device for diffusing volatile substances, which comprises a container (1) which contains a material with said volatile substances, a porous diffuser (2) which is impregnated with said material with the volatile substances, and a protective sheet (3) which is removed before the first use of the diffusion device, wherein the device also comprises a barrier layer (4) equipped with a window (41), with said barrier layer (4) joined to the container (1) and placed between the porous diffuser (2) and the protective sheet (3). Thanks to the presence of the window, the volatile substances are diffused at a high diffusion rate from the moment the protective sheet is removed.

Description

[0001] The invention relates to a device for diffusing a volatile substance comprising a container and a protective sheet removed from the container to enable the diffusion of said volatile substance. Background technique [0002] Devices for diffusing volatile substances, such as insecticides or fragrances, into the air, consisting of containers with active ingredients in solid, liquid or gel form, are well known in the prior art. [0003] The active ingredient is typically separated from the exterior of the container by a semi-permeable membrane barrier or porous diffuser, allowing the active ingredient to diffuse into the air in a gaseous state through the semi-permeable membrane. [0004] One of the disadvantages of currently known solutions is that, since semi-permeable barriers only allow the passage of the active ingredient in the gaseous state, thereby controlling the rate of release of the active ingredient, they do not allow sufficient quantities of Volatile substanc...
