A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.

The invention relates to a bag contour welding tool for welding a foil to form an open bag, where the bag contour welding tool has a recess between two head lines, to a device for filling this bag with this bag contour welding unit, to a welding tool for airtight sealing of an opening of a bag for medical purposes with a bag contour welding unit, to a method of filling a bag with a device that has a filling needle, the bag being manufactured with a bag contour welding tool, to a method of manufacturing a bag with a bag contour welding tool, to a plant for manufacturing and filling a bag, the bag being manufactured with a bag contour welding unit, and to a bag which is manufactured and filled with this plant. The invention allows a filling of a bag, in particular a bag for medical purposes, without the necessity of providing a filling port on the bag. In this way, resources and costs can be saved, preventing damage to the environment.

A package for use with a beneficial agent delivery device. The package includes at least one filling chamber having a sealed penetrable access region, at least one compartment configured to hold a content, wherein the content includes at least one of a beneficial agent or a constituent of a beneficial agent, and at least one channel connecting the at least one filling chamber in fluid communication with the at least one compartment. At least a portion of the package is resealable to contain the content.

Dispensing devices can include buffers. This obviates the need for continually pumping the device to dispense spray or foam. A buffer can be spring loaded, spring loaded combination, elastomeric or gas, and can be in line or adjacent to a piston chamber. Such sprayers and foamers can be mounted upside down. With a buffer, a piston chamber can deliver a greater amount of liquid per unit time than can be dispensed through the nozzle(s). The fraction of liquid that cannot be dispensed can be sent to the buffer for dispensing after the piston downstroke has completed. Volume of the piston chamber and buffer, pressure response of the buffer, throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

Device for fixing a connection to an OPW airbag, with an expansion sleeve (2), with a plurality of expansion shells (4), and a mandrel (6) extending longitudinally through the expansion sleeve (2) having a stretching piece (8) arranged in the vicinity of the expansion shells (4), the outer diameter of which stretching piece is greater than the inner diameter of the expansion shells (4).

The invention relates to a plastic-processing joining system and to a method for operating a plastics-processing joining system. It is known to feed plastics components by means of transport systems for processing purposes to a main material transport means, for example moving film path, in order to produce bags for medical purposes. Individually controlled movable workpiece carriers for the components are provided, or in addition to a work conveyor path for the workpiece carriers, a path for temporary parking is provided for a separate multitude of workpiece carriers.

A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface. Each sealing station is configured to perform an integrated impulse sealing and cooling cycle.

A package for use with a beneficial agent delivery device. The package includes at least one filling chamber having a sealed penetrable access region, at least one compartment configured to hold a content, wherein the content includes at least one of a beneficial agent or a constituent of a beneficial agent, and at least one channel connecting the at least one filling chamber in fluid communication with the at least one compartment. At least a portion of the package is resealable to contain the content.

A system and method for producing a medical bag with an HF welder that uses upper and lower dies each having a plurality of electrode lamellae arranged such that they are alternatingly polarized relative to adjacent lamellae and opposing lamellae. Interspersed dielectric materials may be used to impart contours onto the film material to produce a patterned bag.
