Abstract: A pressing mechanism for miscellaneous packs dispensing fluidic products comprising a capsular body in which a hollow actuator stem is slidably mounted to perform downward and upward movements with the outflow and backflow provided by a bellows with an elastic memory. An upper end of the bellows is coupled to a corresponding part of the actuator stem by a locking ring, and is also coupled to a button/nozzle, while the lower end of the bellows is supported on the capsular body. The actuator stem is slidably guided by an annular cap, below which the lower end of the actuator stem is coupled to a piston and a first check valve, which, together with a second check valve, allows the actuation of the actuator stem.

Abstract: A dispenser for discharging pharmaceutical liquids in the form of individual drops, having a liquid store, a pump device with a pump chamber with a variable volume, and a dispensing opening. The dispenser additionally has a membrane part which delimits the pump chamber on one side and which changes the volume of the pump chamber by moving and/or deforming. The dispenser has a housing, within which the pump device is provided, and an actuation button movable relative to the housing between a non-actuated starting position and an actuated end position to move or deform the membrane part and to decrease the size of the pump chamber to discharge the liquid. The membrane part is secured to the housing and to the actuation button. The pump chamber achieves a high degree of compression and a toggle switch is used as the actuation button.

Abstract: A biasing member for use in reciprocating dispenser pumps is contemplated. The member is made completely of polymeric materials and is suitable as a direct replacement for metallic coil springs. The biasing member includes spiral shape defined by inner and outer helix traces, with a series of perforations provided along one or both of those traces. These perforations, in conjunction with thinned channels, the size and shape of holes, and the size and shape of apertures, all cooperate to allow for a spring with sufficient resilience and greater spring force in comparison conventional, all-polymer biasing members.

Abstract: A microstructured passage module for aerosolizer is disclosed. The module includes a plate overlaid by a cover, an entrance, an exit, a plurality of protrusions and a plurality of pillars. The protrusions and pillars project from and are integral parts of the plate. Further, the plate can be divided into a first zone proximate to the entrance and a second zone proximate to the exit. The protrusions are arranged into parallel rows in a direction from the entrance to the exit and form parallel passages therebetween in the first zone for the liquid to flow along. The protrusions in each column are spaced from one another by tunnels. The pillars are interposingly disposed in the second zone and define certain channels therebetween. Moreover, a plurality of pillars further disposed in the passages increase a flow resistance for the liquid flowing through the passages.

Abstract: The disclosure discloses a dual-spring all-plastic vacuum pump which includes a base and a pressing head. A feeding hole is formed in a bottom of the base, an accommodating cavity is defined by assembly of the pressing head and the base, the feeding hole is in communication with the accommodating cavity, and a limiting cover, a plastic one-way spring, a discharging member and a plastic reset spring are disposed in the accommodating cavity. The limiting cover surrounds the feeding hole, a guide hole in a top of the limiting cover is in communication with an interior of the limiting cover, the plastic one-way spring is clamped between the base and the limiting cover, a fixed end of the plastic one-way spring is in connection and communication with the feeding hole, a stressed end of the plastic one-way spring is in communication with the guide hole, and the fixed end and the stress are opposite. The discharging member is disposed between the pressing head and the limiting cover, the discharging member penetrates through the guide hole and is in communication with the stressed end, and the discharging member is configured to receive materials to the pressing head for output. The plastic reset spring is clamped between the discharging member and the limiting cover. Pressing of the pressing head is configured to push the discharging member to compress the plastic one-way spring. By means of the solution, a metal spring is replaced with a plastic spring, and the problem that an existing pump head is inconvenient to directly recycle is practically solved.
