A cartridge for a dispensing device has at least one inherently non-rigid, elongate film pouch, which has a chamber for receiving a composition. The cartridge also has a head part for interacting with the film pouch. The head part has an inherently rigid insert, which is connected to the film pouch on a side facing the head part. A connecting device is provided, which can connect the insert to the head part in a form-fitting and/or force-fitting manner. The insert has at least one first connecting element of the connecting device and the head part has at least one second connecting element of the connecting device.

Cartridge for a dispensing device

A cartridge for a dispensing device contains at least one elongate film pouch, which is inherently non-rigid and which has a chamber for receiving a composition. The cartridge also contains a head part for interacting with the film pouch. The film pouch has an opening on a side facing the head part which is closed by a cover. The insert is conical on a side facing the head part. A method can be used for producing such a cartridge.

Cartridge and method for producing a cartridge

A head part for a cartridge is provided for interacting with a dispensing device. The head part has a first receiving region for interacting with a first container and a second receiving region for interacting with a second container. The first receiving region is connected to a first channel and the second receiving region is connected to a second channel which is separated from the first channel at least in regions. A control device is arranged in at least one of the channels for controlling a volume flow of a composition guided through the corresponding channel. A cartridge for a dispensing device has such a head part.

A sprue dowel has a radially projecting embeddable portion () and an attachment portion () formed as a hollow cylindrical shaft () provided with a plurality of spaced from each other, furrowed retaining projections () formed on an outer circumference of the shaft and extending parallel to a longitudinal axis () of the sprue dowel ().

Sprue dowel

A tie rod, for insertion into an anchorage where it is secured by at least one of an organic and inorganic mortar composition has an axially extending shaft ( ) with an axially extending connection section ( ) and an axially extending anchoring section ( ). The anchoring section ( ) has at least two conically shaped members, one following the other in the axial direction and with the outside diameter of the members increasing toward a leading end of said anchoring section. The conically shaped members ( ) include a first cone ( ) at the leading end of the shaft, inserted first into the anchorage and secured to the shaft ( ) so that it cannot be shifted axially. At least one second cone ( ) separate from the first cone can be slipped onto the anchoring section ( ) of the shaft so that it can be shifted to a limited axial extent along the anchoring section ( ).
