A method of manufacturing a pouch container, includes: forming a pouch bag having one open end, by fusion-bonding a resin layer on an inner side of an end of a first film, with a resin layer on an inner side of an end of one or more second films; molding a mouth part member made of a resin, including a brim portion and a standing portion; attaching a lower surface of the brim portion of the mouth part member made of the resin to an outer resin layer of the first film of the pouch bag, by integrating the resins, using one of ultrasonic, heat, or high-frequency welding; filling the pouch bag with contents from the one open end of the pouch bag; and sealing an inside by fusion-bonding the one open end of the pouch bag to seal the pouch bag.

The invention relates to a dispensing device (2) for dispensing a fluid. The dispensing device (2) comprises a pump device (4) for conveying the fluid from a container (3). The pump device (4) can be actuated preferably by means of an actuating lever (21) of the dispensing device (2) and/or is formed by a flexible bellows (5). Furthermore, a dispenser (1) for dispensing a fluid with a container (3) and a dispensing device (2) is disclosed.

The present invention concerns a system (1; 501; 601; 701; 801) for dispensing a fluid (L), comprising a container (C; C′) for the fluid (L) and a device (10; 210; 210′; 310; 410; 410′) for dispensing the fluid (L). The device (10; 210; 210′; 310; 410; 410′) comprises a collapsible chamber (20) which defines a volume (V) suited to receive a quantity of said fluid (L) to be dispensed. The chamber (20) is defined by a first portion (30) and a second portion (130) mutually coupled with each other, wherein the first portion (30) comprises an area connected to the container (C; C′) and wherein the second portion (130) comprises an area connected to the container (C; C′).

A device for delivering a predetermined amount of at least one substance to a body orifice of a subject includes a) a container for containing said at least one substance; b) a delivery end for placement in proximity to the orifice, the delivery end being in fluid communication with the container; c) a valve mechanically connectable to said container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end; and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice; d) a trigger mechanism adapted to reconfigure said valve from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, and vice versa; and e) a fluid tight chamber.

A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

A dispenser system for dispensing a fluid product comprises: an elongated container containing the fluid product to be dispensed, a pump assembly coupled with the elongate container from the distal end, a piston which is slidably positioned in the container at the closed proximal end and contacting with the fluid product, and a standing cap. The standing cap has an opening for engaging the pump assembly, and has a supporting structure opposite to the opening, wherein the supporting structure comprises one or more supporting sections that define a supporting plane, wherein the dispenser system, when in a main standing position, stands upon the supporting structure of the standing cap, with the closed proximal end of the elongated container is on the topmost. Further the supporting structure of the standing cap has a projected area on the supporting plane which is larger than the largest cross-sectional area of the elongated container.

A pump dispenser for providing and withdrawing liquids including a bottle (1), having a bottle opening (3) for storing and providing the liquid, and a pump lid (2) on and/or in the bottle opening for metered withdrawal of the liquid. The pump lid has a metering pump (4) with a manually operated actuation element, and further includes a lid (6) for closing the bottle and an output device (7). The bottle has a replenishment opening (9) provided in addition to the bottle opening. A replenishment system includes a pump dispenser (33) per usage location (30) and a transportable storage tank (19) for liquids for replenishing the pump dispensers. A filling apparatus (13) withdraws the liquid from the storage tank (19) and introduces the liquid into the pump dispensers (33), the filling apparatus (13) being provided with a filling nozzle (14) or spike for the replenishment openings (9) of the bottles.

An aerosol assembly for a medicament delivery device is provided having a nozzle chip assembly including a carrier and a nozzle chip provided on the carrier, a holding structure having a fluid channel extending through the holding structure, wherein the nozzle chip assembly is configured to be mounted into the fluid channel such that fluid flowing through the fluid channel passes through the nozzle chip, and an elastic sealing member configured to be arranged with a tight fit in the fluid channel, the sealing member having a central through-opening configured to receive the nozzle chip to seal the nozzle chip towards the carrier.
