Abstract

The invention refers to a device for evaporating volatile substances comprising: a container of a liquid volatile substance, and a vapour permeable membrane (1) and a thermoplastic porous or fibrous laminate (2) bonded together. Said container is closed at its opening by said vapour permeable membrane (1) and the fibrous laminate (2), wherein the fibrous laminate (2) is welded to the thermoformed part of the container.

Description

technical field [0001] The present invention generally relates to devices for vaporizing volatile substances, in particular volatile substances of complex chemical composition, such as certain types of fragrances and / or pesticides. [0002] More specifically, the present invention relates to a reinforced membrane structure in which a semipermeable membrane is laminated with a fiber laminate or a capillary laminate. Background technique [0003] Volatile material vaporizer devices for diffusing air fresheners, pesticides or similar chemicals are well known. [0004] It is well known in the market that containers containing volatile substances such as pesticides or fragrances are closed by semi-permeable membranes. Most of these products consist of polyolefin monolithic films. Due to the high selectivity of polyolefins, and the complexity of some volatiles (very complex fragrance compositions), these products usually have rather low evaporation rates and accept a limited num...
