Abstract
Abstract The packaging is particularly suitable for containing hair coloring components, namely the hair color itself and a second fluid, usually peroxide, which must be stored separately and well mixed immediately before being applied to the hair. The two fluids, for storage purposes, are housed in two different concentrically disposed containers (1,6). Immediately before hair treatment in the inner container (6), the base of which is adjacent the base member (2) of the outer container (1), is displaced outwardly as far as a stop (8) and thus simultaneously a good mixing of the two fluids is effected. A sealing lip (17), which releases possible overpressure, a deformable base member (2), and a groove (21) prevent the occurrence of overpressure inside the two containers.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
309 words
A two-component packaging for pourable media, having a storage position and an operating position, comprising: an outer container, having an inner side, and containing during the storage position, a first component of the media; an elongated inner container, containing during the storage position, a second component of the media, said inner container being partially disposed within said outer container and being longitudinally displaceable from the storage position to the operating position, said outer container having a neck portion containing a sealing lip made of resiliently flexible material and having a free end disposed substantially parallel to the longitudinal axis of said inner container and being rigidly connected to said inner side of said outer container, said sealing lip lying closely against said inner container in a contact region and extending in said contact region outwardly from the interior of said outer container in the direction towards said free end of said lip, so as to release into the ambient possible overpressure in said outer container, said inner container also having a lateral wall with at least one projection extending radially outwardly and said outer container having a recessed stop for said projection in the vicinity of said sealing lip, so that said projection limits the longitudinal displacement of said inner container during the transfer from the storage position to the operating position, said outer container having a lateral wall and a base member having a central zone surrounded by annularly disposed projections and lying closely against said lateral wall of said inner container in the storage position, said base member being more flexible and more easily deformable than said laterial wall of said outer container, so that an overpressure in said inner container can be reduced by the deformation of said base member allowing an amount of a media to pass from said inner container to said outer container.

A two-component packaging for pourable media, having a storage position and an operating position, comprising: an outer container, having an inner side, and containing during the storage position, a first component of the media; an elongated inner container, containing during the storage position, a second component of the media, said inner container being partially disposed within said outer container and being longitudinally displaceable from the storage position to the operating position, said outer container having a neck portion containing a sealing lip made of resiliently flexible material and having a free end disposed substantially parallel to the longitudinal axis of said inner container and being rigidly connected to said inner side of said outer container, said sealing lip lying closely against said inner container in a contact region and extending in said contact region outwardly from the interior of said outer container in the direction towards said free end of said lip, so as to release into the ambient possible overpressure in said outer container, said inner container also having a lateral wall with at least one projection extending radially outwardly and said outer container having a recessed stop for said projection in the vicinity of said sealing lip, so that said projection limits the longitudinal displacement of said inner container during the transfer from the storage position to the operating position, said outer container having a lateral wall and a base member having a central zone surrounded by annularly disposed projections and lying closely against said lateral wall of said inner container in the storage position, said base member being more flexible and more easily deformable than said laterial wall of said outer container, so that an overpressure in said inner container can be reduced by the deformation of said base member allowing an amount of a media to pass from said inner container to said outer container.
Claim 3
Dependent Claim
44 words
A packaging as claimed in claim 1, in which the projections disposed in an annular manner are formed as an annular elevation (2B) which lies closely against the inner side of the lateral wall (7) of the inner container (6) in the storage position.
Claim 4
Dependent Claim
24 words
A packaging as claimed in claim 1 or 2, in which the base member (2) has a central zone (2A) which is inwardly retracted.
Claim 5
Dependent Claim
72 words
A packaging as claimed in claim 1, in which in the region of the sealing lip (17) on the side thereof facing the interior of the outer container (1) a chamber (19) is provided and the projection (8) on the outer side of the inner container (6) is formed in such a way that during the transfer into the operating position it can be pushed into the interior of the chamber (19).
Claim 6
Dependent Claim
77 words
A packaging as claimed in claim 1, in which the outer container (1) has an internal thread (15) on its inner side and the inner container (6) has an external thread (16) on its outer side, and the two threads are disposed in relation to the longitudinal dimension of the two containers such that, in the storage position, the thread (16) of the inner container (6) is screwed into the thread (15) of the outer container (1).
Claim 7
Dependent Claim
46 words
