Method and device to evaporate active ingredients from a liquid solution

Abstract

The present invention relates to a method and a device to evaporate low volatility active substances or ingredients from a liquid solution contained in a reservoir (2). The device comprises at least one liquid retaining support and dispensing means (14) arranged in a casing (1) at a distance and in a suitable position for dispensing doses of said liquid solution on said support by means of a push-button (6). The device further has a timer adapted to allow the operation of said dispensing means in selected time periods, said time periods being greater than the time necessary for evaporating most of the solvent and active ingredient from the support.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a method and a device to evaporate low volatility active substances or ingredients from a liquid solution. The invention is preferably used to evaporate an insecticide substance at low temperature or even at room temperature.[0002]More specifically, the invention includes distributing in the air active ingredients in a controlled manner to control the efficacy of the effect of the active ingredient considering the effective time of evaporation of the liquid, such that the beneficial effects of the active ingredients can be offered to the user as long as possible.[0003]The field of application of the present invention is the industrial sector dedicated to the devices that evaporate volatile products such as perfumes, deodorants, odor and smoke neutralizes, bactericides, insect repellents and air fresheners for interiors in general.BRIEF DESCRIPTION OF RELATED ART[0004]In dispensing volatile substances to perfume o...

Benefits of technology

[0018]The invention mainly improves two critical points in the performance of the volatile product: on one hand, it prevents impregnating the porous material with the liquid in the factory, such that the user can use the effects of the in situ transfer of the liquid to the evaporator support, because all the active ingredient dispensed is used since nothing is lost d...

Problems solved by technology

However, these aerosol devices may not be completely effective or inexpensive because the effects of the active ingredients are concentrated in the instant in which the spraying starts and then decrease rapidly.

To date, known evaporators incorporating an absorbent element made of porous material containing the volatile substances are disposable devices having the drawback that said element is impregnated in the factory during the process for manufacturing the product, such that the user receives the element impregnated only with the active ingredients because the solvent spontaneously evaporates beforehand, part of the active ingredient possibly having evaporated during the product stor...
