Abstract
The invention concerns a container for packaging a liquid () to be dispensed in drops. The container is reversibly deformable by air input and is equipped with a head () for dispensing liquid through a nozzle (). The dispensing head () comprises a recessed body () which is nested inside a neck () of the container and which holds a hydrophobic microporous pad () arranged upstream of a chamber (). Chamber () is provided with an air reservoir for preventing the liquid from passing through the microporous pad () between two liquid dispensing operations, when the nozzle () is sealingly obstructed with a cap (), and for drying a partly hydrophilic and hydrophobic filtering membrane () arranged in the dispensing head ().
