Abstract: The invention concerns a device comprising a flask (1) with variable internal volume having a rigid neck (5) wherein is arranged the body (3) of a dispensing head (2) ending in a conduit (41) discharging the liquid and containing a microporous pad (6) for generating a head loss regulating the liquid flow pushed therethrough into a distribution chamber (31) communicating with said conduit. The pad is advantageously made of a material inert with respect to the liquid and combined with an antibacterial filtering element (9) preventing outside air from entering the flask. It evenly occupies the body (3) over the whole cross-section of the liquid passage.

Abstract: Liquid is enclosed in a resiliently deformable container, the neck of which has a microfiltering membrane which is permeable to the liquid but impermeable to air when wet. Since the container resiliently recovers its shape after it is deformed, the liquid remaining in contact with the outside of the membrane after use is sucked back in and the membrane is kept moist until the next time the container is used.

Abstract: A package for a liquid which is purified includes a neck with a lock-chamber slidable therein. The lock-chamber includes a purifying substance through which the liquid passes when dispensed. At one end of the lock chamber, a plug is positioned to block passage of the liquid through the lock-chamber when the lock-chamber is projected from the neck and to allow passage of the liquid when the lock-chamber is pushed down into the neck.

Abstract: Pharmaceutical preparations with anti-allergic activity for local administration, which contains, a pharmaceutically acceptable salt of N-acetyl-(alpha, beta)-aspartyl glutamic acid in the form of ophthalmic preparations, nasal solutions, bronchial aerosols, and skin ointments.

Abstract: A chromone derivative has the formula: ##STR1## in which one of the radicals R, R' is a hydrogen atom or a lower alkyl radical and the other of the radicals is an aminoalkyl oxy benzoyl group having the formula: ##STR2## The derivative can be of use in the pharmaceutical industry in drugs for treating heart disorders.
