An apparatus for depositing an extrudable substance comprises a bracket and a sleeve, comprising an inner tubular sleeve wall and an outer tubular sleeve wall. The sleeve is coupled to the bracket and is rotatable relative to the bracket. The apparatus also comprises a cartridge, comprising an inner tubular cartridge wall and an outer tubular cartridge wall. The cartridge is configured to be positioned between the inner tubular sleeve wall and the outer tubular sleeve wall. The apparatus also comprises a valve, configured to be communicatively coupled with the cartridge, a nozzle, configured to be communicatively coupled with the valve, a linear actuator to control flow of the extrudable substance from the valve to the nozzle, an annular plunger, positioned between the inner tubular cartridge wall and the outer tubular cartridge wall, and a push-lock pressure cap, configured to be hermetically coupled with the cartridge.

In one aspect, the invention is directed to a portable paste dispenser having a container for storing paste, the container having a cylindrical part and a conical part, a nozzle at the end of the conical part, a piston, disposed inside the cylindrical part of the container, and a shaft connected to the piston, the shaft having a limited foldability so that when the shaft is pushed towards the piston, it still is able to move the piston along the cylindrical part, where the piston includes foldable bellows walls, thereby upon applying force on the piston, the piston straightens up, resulting in a conical form correspondingly to the conical part, thereby allowing fully emptying the container.

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 portable liquid dispensing device which includes a liquid cartridge containing a prefilled desired liquid supported within the dispensing device. A dispensing mechanism is positioned within the device for engagement with the liquid cartridge for dispensing a desired amount of liquid from the liquid cartridge to an outlet exiting the device. An actuator button is also provided for actuating the dispensing mechanism and dispensing the desired amount of liquid through the outlet of the dispensing device. The dispensing mechanism includes a central shaft with a first end engaged with the actuator button, a second end is positioned adjacent the outlet, and a plunger assembly is supported on the central shaft intermediate the first and second ends for substantially sealed engagement with an internal surface of the liquid cartridge and central shaft to move the plunger assembly and liquid toward the outlet upon actuation of the actuator button. Upon deactivation of the actuator button, the central shaft slidably moves or retracts through the plunger assembly, without moving the plunger assembly.

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 dispensing container for viscous products comprising: a cream pot having an inner cylinder that defines a storage volume configured to store a viscous product; a cap configured to close the cream pot and having a dispensing outlet; a screw rod rotatably connected to the cream pot; a piston having an inner thread and being coupled to the screw rod such that rotation of the screw rod leads to movement of the piston in the inner cylinder along a longitudinal axis of the screw rod to reduce the storage volume of the inner cylinder and to dispense the product through the dispensing outlet; wherein an indexing mechanism is provided that is configured to lock the screw rod in a plurality of rotational positions with respect to the cream pot, wherein the indexing mechanism comprises indexing spring elements located at the screw rod and indexing sections located at a bottom of the cream pot, wherein the indexing spring elements of the screw rod are configured to interact with the indexing sections of the cream pot in order to lock the screw rod with respect to the cream pot.

A container assembly comprising a container with a container neck, a syringe, and a closure with a cap portion having an end wall, wherein the syringe plunger of the syringe is connected to the end wall. The syringe is enclosed by the container body and the cap portion when the cap portion is aligned in a closed position on the container. The syringe is removable from the container when the cap portion is in the open position.

This invention relates to an apparatus for dispensing a viscous fluid whether in combination, disassembly or assembly. The apparatus comprising a cartridge, reservoir or tube containing the fluid and having an openable or opened outlet structure which, when opened, allows the expression of the fluid from a created outlet aperture. A nozzle is engaged or engageable to the outlet structure and/or cartridge, reservoir or tube whereby fluid expressed from the outlet aperture can subsequently move to and be expressed from the nozzle outlet. The openable or opened outlet structure is adapted to provide on opening at least one outlet aperture having a size of area A; and wherein the nozzle has or is adapted to be cut to provide a nozzle outlet of area B, area B being greater than or equal to area A.

A container assembly comprising a container with a container neck, a syringe, and a closure with a cap portion having an end wall, wherein the syringe plunger of the syringe is connected to the end wall. The syringe is enclosed by the container body and the cap portion when the cap portion is aligned in a closed position on the container. The syringe is removable from the container when the cap portion is in the open position.
