Disposable packaging, comprising a container (1) that defines a main
compartment (2) and at least an additional compartment (3). The container
(1) is bowl-shaped and is closed on the upper side by a film, or by a
cover, in order to prevent the main food component contained inside the
main compartment (2)--from coming out. Moreover, the additional
compartment (3) is closed by a slidable sealing system of the
cylinder-piston type. In the closure position of the piston, which is
formed by a plug (14), the food component contained in the additional
compartment (3) cannot mix with the food component located in the main
compartment (2), whereas in the opening position of the plug (14), the
dressing/seasoning may leak from the additional compartment (3) through
lateral apertures of the plug (14), at the time the user turns over and
shakes the packaging.
