DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a two-component packaging for pourable media, which comprises an outer container for one component and an elongate inner container for the other component. The inter container, in storage position, is located at least partially inside the outer container and is slidably displaceable outwardly into an operating position.
Packagings of this type have become known in numerous different embodiments but hitherto these have not proved absolutely satisfactory with respect to storage and/or use.
DISCLOSURE OF THE INVENTION
The invention is based on the object of providing a new type of two-component packaging for pourable media by simple constructive measures without particular additional expense, which packaging may be both easily opened and handled by the user and in which the components are well mixed for use and the filling of the packaging can satisfy the requirements of series production.
This object is achieved in the case of a two-component packaging of the type initially described in that in the neck section of the outer container a sealing lip is provided which is rigidly connected to the outer container and sits close to the inner container; at its outer side the inner container bears a radially outwardly extending projection, and the outer container, in the vicinity of the sealing lip, bears a stop for this projection which limits the longitudinal displacement of the inner container during the transition from the storage position to the operating position; and the outer container has a base member whose central zone is surrounded by projections which are disposed in an annular manner and which, in the storage position, lies closely against the lateral wall of the inner container.
Further developments of the invention which in particular eliminate the diffusion of air/oxygen into the interior of the packaging, and measures which, if an inner overpressure builds up, render this inoffensive or vent it, are characterised in the subclaims and will subsequently be described in connection with the accompanying drawings which illustrate preferred embodiments and are partially schematically simplified. In the drawings, parts corresponding to each other are given the same reference numerals and all details which are not necessary for understanding the invention have been omitted.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a longitudinal section through a two-component packaging comprising an outer container and an inner container, the latter being in the storage position;
FIG. 2 shows the upper part of FIG. 1 on an enlarged scale;
FIG. 3 shows the lower part of FIG. 1 on an enlarged scale, indicating in broken line the effect of an overpressure in the inner container;
FIG. 4 is similar to FIG. 1 but with the inner container in the operating position, i.e. drawn out in the longitudinal direction;
FIG. 5 shows the middle part of FIG. 4 on an enlarged scale;
FIG. 6 shows the lower part of the packaging inverted for filling, before fitting the base member;
FIG. 7 is similar to FIG. 6 but on an enlarged scale and with the base member applied and welded to the edge of the outer container;
FIG. 8 shows another embodiment of a two-compartment packaging in longitudinal section;
FIG. 9 is a detail (in longitudinal section) of another embodiment similar to FIG. 7, in which the outer side of the central zone in the base area of the inner container is covered by an aluminum bonding sheet;
FIG. 10 is a longitudinal section through a modified embodiment, similar to FIG. 1;
FIG. 11 is a longitudinal section through a further embodiment, similar to FIG. 10; and
FIG. 12 is a detail of a further embodiment, similar to FIG. 7, with a modified base member.
BEST MODE OF CARRYING OUT THE INVENTION
In FIGS. 1 to 7 a two-component packaging for hair colour is illustrated. The packaging comprises two concentric containers which are connected to each other in a very special manner.
The outer container 1, which has a base member 2, a lateral wall 3, and a neck section 4, contains fluid pe
