Definitions
- the present invention relates to a device for slow delivery of a liquid.
- the adsorbent materials in particular certain polymer gels, have the property of slowly diffusing a liquid which they have previously adsorbed. Such materials are thus the subject of various applications in the fields of olfaction, cosmetics and pharmacy (patches), to slowly diffuse perfumes or liquids containing active ingredients. However, such materials do not allow to control precisely the regularity with which the liquid is diffused. In addition, the liquid trapped in the microstructure of the adsorbent material remains exposed to air and gradually loses its original characteristics, the most volatile components evaporating first and others degrading by oxidation. Finally, the total volume of the adsorbent material to be used is a function of the amount of liquid to be adsorbed, and the ratio between the bulk of the material and the volume of adsorbed liquid is generally not very advantageous.
