In some examples, an apparatus can include a syringe body including an electrical interface at a side surface of the syringe body, an interface at an end of the syringe body including an output at a distal surface of the syringe body, a print material particles reservoir located in the syringe body, and a structure to adapt a volume of the print material particles reservoir to move print material particles out of the print material particles reservoir through the output, where in response to the volume adapting structure moving from a first position to a second position, a signal is transmitted by the electrical interface.

An incremental advance dispenser includes a barrel which has a longitudinal axis, a muzzle end, and an opposite breach end. A shuttle is slidably connected to the barrel and movable with respect to the barrel along the longitudinal axis. A cup which carries a product is movable within the barrel along the longitudinal axis. The shuttle is positionable to an extended position toward the muzzle end of the barrel, and to a retracted position toward the breach end of the barrel. Movement of the shuttle to the extended position from the retracted position causes the cup to move an incremental distance toward the muzzle end of the barrel.

A container assembly to facilitate liquid transfer from a donor container to a recipient container that includes utilizing a first container and a second container, whereby the second container has a piston coupled to a sidewall thereon in a watertight configuration and that is operably configured to linearly translate within a second container cavity. The assembly includes a container linking structure selectively removably couplable to the second container in a watertight and male-female coupling configuration, a stem member selectively removably couplable to the piston in a male-female coupling configuration and having a grasping portion thereon, and a straw member attached to the linking structure, wherein the stem member is configured to apply a force on the piston to linearly translate the piston to generate a negative pressure within the enclosed conduit for transportation of liquid configured to be housed in the first container cavity to the second container.

The invention relates to a metering device (1) for the metered application of a highly viscous product onto a substrate (2), comprising a housing (3) with an inner side (7) and an outer side (6), a cartridge (10) forming a receiving space (14) for the highly viscous product to be metered, a piston (20) and a spring element (17), wherein at least one engaging element (22) is formed on the inner side (7) of the housing (3) and a row of neighboring engaging recesses (21) is formed on the piston (20), wherein both the engaging element (22) and the engaging recesses (21) are arranged outside of the receiving space (14), and wherein the engaging element (22) engages into an engaging recess (21) on the piston (20) with an actuation of the metering device (1), and wherein, after an actuation of the metering device (1), a returning movement of the housing (3) into the starting position thereof brings about a transition of the engaging element (22) from the engaging recess (21) into a neighboring engaging recess (21).

A dosing dispenser for a flowable composition includes a housing, a traveler, a plunger, and a driver. The housing defines a chamber, and the plunger is movable within the chamber. The traveler is at least partially within the chamber and configured to selectively position the plunger. The driver is at least partially within the chamber and configured to movably position the traveler relative to the driver. The driver is engaged with the traveler within the chamber.

A Propellant-Free continuous dispenser for dispensing liquid or viscous materials under pressure. The container comprises a tension surface, and a bag containing the liquid to be dispensed, which is in contact with the tension surface. An actuatable valve to which the bag is open serves to controllably release the liquid from the bag, and a diaphragm forms a floor to the tension surface underneath the bag. The diaphragm is elasticated and presses the bag against the tension surface to flatten the bag, thus to expel the contents under pressure.

An injection device able to evacuate air bubbles trapped with injectable liquid includes a needle tube, a push rod slidable installed in the needle tube and a piston secured on one end of the push rod. The piston includes a main body and a cover, the main body defines a through hole and an exhaust passage in air communication with the through hole. The cover is secured on the main body to shield the through hole and the exhaust passage, and the cover defines an exhaust hole in air communication with one end of the exhaust passage to allow gas but not the liquid to escape from under the piston.

A volume cream vessel is provided, which includes a cream vessel configured to contain a cosmetic content, a rim member mounted on the upper part of the cream vessel, a pumping device seated on the rim member and configured to upwardly pump the cosmetic content inside the cream vessel, a pressing member disposed on an upper part of the pumping device, and a cover member configured to cover an upper part of the pressing member. One edge of the pressing member is coupled to the rim member so as to operate the pumping device by a pressing operation.

A sealed device (1) for protecting and dispensing pasty or creamy products (7), includes a reservoir (2) containing the product (7) and suitable for receiving, at the bottom end thereof, a longitudinally movable sealing plug (3). The reservoir (2) is longitudinally movable like a piston in a pump body (4) and it is forced into the closed position by a spring element (5) that cooperates in compression with a lateral outer projection (2e) of the reservoir (2) and with the top of the side wall (6b) of the base (6) attached to the pump body (4). The pump body (4) includes an elastically deformable upper membrane (4a) providing a pump function and also includes, on an upper lateral wall thereof (4c), a lateral opening (4e) for dispensing the product (7). The assembled reservoir (2) and pump body (4) form a system suitable for circulating the product (7) via a compression chamber (C) supplied from the reservoir (2) by at least one upper inlet orifice (2b). The device is particularly suitable for the hygiene, pharmacy and cosmetics fields.

A container assembly to facilitate liquid transfer from a donor container to a recipient container that includes utilizing a first container and a second container, whereby the second container has a piston coupled to a sidewall thereon in a watertight configuration and that is operably configured to linearly translate within a second container cavity.
