Abstract: An injection device incorporating a dose setting mechanism is presented where the dose setting mechanism contains a fail safe feature that activates during an interrupted dose delivery event. A dose selector having a projecting rib engages a protrusion on a snap element to prevent the dose knob from moving distally if a user removes an axial force in the proximal direction during dose delivery. The dose setting mechanism can further include a reuse prevention feature.

Abstract: An injection device incorporating a dose setting mechanism is presented where the dose setting mechanism contains a dose selector having one or more dose stops corresponding to a finite set of predetermined fixed doses, where the set of finite predetermined fixed doses includes a lowest fixed dose and one or more higher fixed doses, and where at least one of the one or more higher fixed doses is equal to the lowest fixed dose plus a fractional amount of the lowest fixed dose. The dose setting mechanism can further include a floating spline that is rotationally engaged with a snap element such that the snap element can rotate relative to the floating spline during both dose setting and dose delivery.

The housing, the blocking element and the biasing member being obtainable by substantially simultaneously 3D printing, so as to be formed from one or more 3D printable materials.

Abstract: A cartridge for an adhesive or a coating, the cartridge including a head part having an outlet, the head part being integrally formed with a cartridge wall. The outlet has one, two or more outlet passages formed therein. A valve is disposed in each one of the one, two or more outlet passages, with the valve being axially and radially fixed in position relative to the head part at a peripheral portion of the valve.

Abstract: A cartridge assembly includes a cartridge and a sleeve, the cartridge having a solid head part and a cartridge wall formed by a film integrally formed with the head part, the cartridge being received in the sleeve.

Abstract: A drug delivery device with a housing configured to connect to a dispensing unit including a compartment containing a fluid, a piston rod configured to move in a proximal direction for ejecting the fluid, and a dosing mechanism including an actuation member to be actuated by a user. The device includes a conversion mechanism configured to convert a movement of the actuation member to a movement of the piston rod. The conversion mechanism includes a dose selector member, which is rotationally fixed to the housing and axially movable with respect to the housing, and a dosing member, which is rotationally movable with respect to the dose selector member. The drug delivery device includes a friction reduction mechanism provided between the dose selector member and the dosing member to reduce friction between the dose selector member and the dosing member.

Abstract: A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

Abstract: A distributor head for a distributor apparatus for distributing fluids onto a surface includes an elongate base element having a fluid volume to receive the fluid, a filling opening connected in a fluid-communicating manner to the fluid volume to fill the fluid into the fluid volume, and a plurality of distributor openings connected in a fluid-communicating manner to the fluid volume to distribute the fluid from the fluid volume. The filling opening arranged at a first longitudinal side of the distributor head and the plurality of distributor openings arranged at a second longitudinal side of the distributor head, the first longitudinal side arranged opposite the second longitudinal side, and the plurality of distributor openings continuously formed in a wall of the base element.

Abstract: A cartridge for a material to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall, with the flexible film bounding a cartridge chamber for the material to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has an outer circumferential surface, and an inner surface of the front end of the flexible film is sealingly and non-releasably connected to the outer circumferential surface of the head part.

Abstract: A piston for a collapsible cartridge for dispensing a material, the piston includes a rigid portion and a flexible portion. The rigid portion has a first diameter, a first end and a second end. The first end is configured to be disposed in a material dispensing direction. The flexible portion has a second diameter less than the first diameter, a first end disposed in the material dispensing direction and a second end disposed in an opposite direction. The flexible portion is disposed on the first end of the rigid portion such that the second end of the flexible portion is disposed to face the first end of the rigid portion. The flexible portion is configured to radially expand and longitudinally compress upon a force applied to the first end of the flexible portion to compress the collapsible cartridge between the flexible portion and an interior surface of a support cartridge.

Abstract: A cap for an applicator includes an inlet, a base having a connection portion embodied for connecting the cap to the applicator or a container formed therein, a head that receives an application part of the applicator within the head, and a projection formed at a top part of the cap. The top part formed at an opposite end to the inlet, and the projection cooperating with an outlet of the applicator. The head includes a cylindrical or conical inner or outer shape and the connection portion has a round inner or outer shape, that is an oval, round or square shape.

Abstract: A dynamic mixer for mixing a multi-component material includes a mixing rotor capable of being rotated about an axis of rotation, the mixing rotor having a coupling socket configured at an end thereof. The coupling socket has a reception space configured to receive at least a part of a polygonal shaped coupling plug of a drive shaft to transfer torque from the drive shaft to the mixing rotor.
