Abstract: A method for fitting a piping nozzle (1) or a part of a piping nozzle (1) in a piping bag (2) comprises placing the piping nozzle (1) in an initial position (3), which initial position (3) is situated at a substantial distance from a piping position (5) located in the piping bag (2), using a piping nozzle applicator (4), which is movable between the initial position (3) and the piping position (5), to releasably engage with the piping nozzle (1) at the initial position (3), using the piping nozzle applicator (4) to bring the piping nozzle (1) from the initial position (3) substantially to the piping position (5) in the piping bag (2), releasing the piping nozzle (1) from the piping nozzle applicator (4) at the piping position (5), and pulling the piping nozzle applicator (4) back from the piping position (5).

Abstract: A device for opening a piping bag for pre-filling comprises first and second gripping surfaces, adapted for clamping an openable end of the piping bag therebetween, wherein the gripping surfaces, while in clamping engagement with the piping bag, are movable relative to each other in a direction substantially parallel with said gripping surfaces. A method for opening a piping bag for prefilling is also disclosed.

Abstract: A method for preparing a piping bag for pre-filling, the set comprising, a thin walled polymer tube, and at least one severance mark extending across the entire width of the polymer tube, partitioning the set into two separable piping bags having a respective openable portion, said openable portions pointing in substantially opposite directions, as seen in a longitudinal direction of the set. The method comprises gripping the set at or near the respective openable portion, positioning the openable portions to point in substantially the same direction, and separating the piping bags from each other along the severance mark.

Abstract: Example embodiments relate to a disposable piping bag, having a container of polymer film. The piping bag may be made essentially from a thin-walled polymer tube, and an outwardly oriented surface of the piping bag may be provided with a rough surface structure. The rough surface structure may have the form of a pattern of raised dots or grooves presenting a surface friction coefficient which may be higher than that of the polymer film.
