The invention relates to a pump of very simple low-cost structure comprising a hollow stem slidable within a cup-shaped body and acting as a compression piston, and a valving element consisting of an elongate rod movable in the cavity within the stem and provided with a conical collar which is urged by a spring to engage and seal against a conical seat within the stem, so that liquid delivery occurs snapwise when the conical collar disengages said conical seat within the stem.

The device comprises a distributor provided with an operating member (8) for a counting means of doses of fluid associated with a mouth (31) of a container (1), a ring nut (4) for fastening the distributor means (2) onto the nouth (31) and elastic means (16) suitable for transforming the translatory motion of said operating member (8) with respect to the ring nut (4) in a rotatory and axially reciprocating motion of a rotating and axially translatable element (9) to cause the appearance of a different numerical index provided on the rotating element (9) at an observation position (19) obtained in the operating member (8).

The invention relates to a nasal dispenser for atomizing pharmaceutical substances which is of elongate form and is traversed by a longitudinal channel having an open end for housing the free end of the stem (4) of a pump or dispensing valve, its other end being intercepted by a wall (7) provided with a hole (8) through which the substance is dispensed. The channel has a stepped cross-section which is a minimum in proximity to said wall. The channel houses an elongate (9) element the cross-sections of which are smaller than their surrounding cross-sections of the channel into which said element is inserted. The length of the portion of smaller cross-section of the profiled element is greater than the length of the minimum cross-section portion of said channel to define an expansion chamber (13) within it. In the free end of the elongate element in proximity to said wall there is provided a circular central recess, from which there extend channels opening into the periphery of the element itself and substantially tangential to the recess, from the centre of which there projects a peg (15) which extends through the hole in said wall to leave a free space for the emergence of the atomized substance.

摘要:
A nasal dispenser for atomized pharmaceutical substances of the type comprising a passage channel of the substance, in such channel it is housed a lengthened shaped element (6) made of plastics, having, along its external surface at least an appendix (15) cooperating with the internal wall of the discharge channel for detaining the shaped element itself.
摘要:
The invention relates to a manually actuated nasal dispenser, suitable for dispensing a liquid single dose in atomized form retained in a chamber (2) which is part of said dispenser: said liquid consisting of or containing a substance having pharmaceutical activity, for instance calcitonin. Said nasal dispenser has a very simple structure, it assures a perfect seal and insulation of the liquid retained in it till the moment of its use, and it is made in such a way that the dispensing of the liquid in atomized form occurs only after that at least a minimum pressure having a predetermined value has been given, thus avoiding droppings of said liquid outside of the dispenser discharging nozzle (12).
