DESCRIPTION:

BRIEF SUMMARY
FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to a multicomponent package.
Such a multicomponent package is known from EP 0 133 293. The two-component package proposed there provides for an inserted cup which can be inserted into the neck opening of an outer container so that two components of the outer container and the inserted cup can be stored separately. By screwing down the screw cap beyond the basic sales position the annular step of the bottom of the cup is struck by an impact edge so that the predetermined breaking line is broken and the inserted cup drops into the outside container so that the two components are brought together. Such a cup, however, needs improvement since it can receive only two components separately and furthermore, due to the complete breaking off of the bottom of the cup, said bottom may come into a blocking position in front of the discharge opening.


SUMMARY OF THE INVENTION

The object of the present invention therefore is to improve the possibilities of use of a multicomponent package of this type, which is of simple structural shape.
By virtue of the invention, a multicomponent package is obtained which has several inserted cups which can be placed one within the other. A first inserted cup is inserted firmly into the neck opening of the outer container. One or more second inserted cups are inserted into the first inserted cup. By further screwing down the screw cap beyond the basic sales position, a predetermined breaking line of each inserted cup is torn. For this purpose, the annular steps are acted on by the impact edge of an impact collar. The cup wall of a second insert cup is advantageously so continued in axial direction on its bottom side that it forms the impact collar for the tearing of the predetermined breaking line of the inserted cup which receives the second inserted cup.
If there is only one second inserted cup, the impact edge formed by the continuation of the wall of the cup strikes the annular step of the bottom of the first inserted cup. Several second inserted cups are also provided, each of which will form impact edges inserted in one another in order to tear open the bottom of the inserted cup which receives in each case the second inserted cup. The loosening of a bottom from the inserted cup is assured in a simple and reliable manner. Cup wall and cup bottom remain connected by a web of material, so that the bottom of the cup is suspended from the cup wall even when the predetermined breaking line has been torn open and does not drop into the outer container.
When the screw cap is screwed down on the outer container, the inserted cups are pushed together in telescopic manner, the annular steps of the cup bottoms being acted on in succession by the impact collars. The innermost second inserted cup is in this case advantageously acted on by an impact collar formed on the screw cap. The second inserted cups are so inserted one within the other that they are axially displaceable. A drive projection is preferably developed on the outer cup wall of the second inserted cup, said projection being arranged between a drive edge and a stop edge and being acted upon by them. If only one second inserted cup is provided then the stop edge is formed by a rim of the first inserted cup which surrounds the neck opening of the outer container. The drive edge is then formed by the end surface of a drive collar which is associated with the screw cap.
If several second inserted cups placed one within the other are provided in order to receive more than merely three components, then the drive projection of each second inserted cup strikes the stop edge formed by the upper edge of the inserted cup receiving it upon the further screwing on of the screw cap. If the last-mentioned inserted cup is also a second inserted cup, it is displaced axially by the striking on its upper edge. The drive projection is so arranged that after the tearing of the predetermined breaking line of the innermost second inserted cup the drive projection is acted upon by
