The invention relates to a feed tank for use in a high-pressure system, said feed tank having a hollow space (3) for accommodating food items, a wall (1) and a temperature-control device (5). The invention further relates to a method for the simultaneous high-pressure and temperature treatment in a high-pressure tank.

A liquid dispensing apparatus (1) includes a liquid contact member (2) that has measuring bores (11, 11). A first piston (3) slides in the first measuring bore (11) and a second piston (3) sliding in the second measuring bore (11). A supply channel (5) communicates with a storage unit (17). An ejection channel (6) communicates with a nozzle (18). A switching valve (4) is disposed in a space in the liquid contact member (2), and that has a first position and a second position. A valve driving mechanism (8) operates the switching valve (4). A piston driving mechanism (9) operates an arm (19) connected to the first and second pistons. The first and second measuring bores are arranged to oppose to each other on both sides of the switching valve (4), and the supply channel (5) and the ejection channel (6) are arranged adjacent to the switching valve.

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.

A container assembly to facilitate liquid transfer from a donor container to a recipient container that includes recipient container with a main body, a bottom sidewall member couplable to the main body, that has a lower surface to enable the recipient container to be placed in an erect orientation, and has a bottom aperture for receiving a selectively removable disc. The bottom sidewall member may include a flange member projecting from an inner surface thereon and that is configured to stop linear movement of a piston placed inside of the main body and moved with a stem that is insertable through the bottom aperture and attachable to the piston, wherein the user moves the piston with the stem to generate a negative pressure to induce liquid in a donor container to be transported to the recipient container.

An applicator for and method of applying a material, and a piston assembly for the applicator. A piston assembly of the applicator is movably engaged within a housing to form a reservoir that is expandable and contractable to, respectively, draw into and push out from the reservoir the material via an opening during, respectively, suction and pressure phases of the applicator. The piston assembly includes an outer seal to prevent ingress of fluid towards the reservoir from an outer side of the piston assembly during the suction phase and an inner seal disposed between the outer seal and the reservoir to prevent egress of material out of the reservoir into a cavity formed between the housing and the inner and outer seals, during the pressure phase. The outer seal moves freely as the applicator is moved to the pressure phase to open the cavity for pressure equalization to prevent suction.

A device for packaging a lubricant, the device including a hollow capillary tube intended to contain the lubricant, the tube including, on the one hand, a first opening closed by a piston arranged to cooperate with a rod movable longitudinally in the capillary tube, and on the other hand, a second free opening through which the lubricant flows when pressure is exerted on the piston with the movable rod.
