`(54) Combination packaging
`(57) Combination package (1) for packaging a first and a second flowable material (2,
`3), which are kept separate until their use and which are mixed together for their use,
`wherein the mixture (4) is removed from a closable removal opening (5). The first
`material (2) is held by a first package part (6) and the second material (3) is held by a
`second package part (7), wherein the first package part (6) is configured to be screwed
`onto the second package part (7). The first package part (6) is configured as an
`essentially rotationally symmetrical screw cap (8) and has at an upper outer side (9)
`the removal opening (5) and at the inner side a downwardly open cuplike container
`(10), which contains the first material (2) and is closed liquid-tight by means of a
`separation film (11) at the container rim (12). The second package part (7) is closed
`liquid-tight by a plug (13), which is provided with a device (15) arranged at the plug
`base (14) for opening the separation film (11).
`The plug (13) is configured as a cup and it closes the second package part (7) firmly
`against axial displacement. The plug base (14) has an inclined base (16), which is
`provided in the edge region (17) with a predetermined breaking zone (18), which is
`torn off from the container rim (12) when the two package parts (6, 7) are screwed
`together, while between an outer side wall (19) of the ...

`27/external thread 29), while between an outer
`Specification
`side wall 19 of the cuplike container 10 and an
`inner side wall 20 of the plug 13 there is a liquid-
`tight connection 21 (Fig. 4 and 5).
`The inclined base 16 has an angle of inclination of
`around 8 degrees, so that there is a relatively short
`path for the separation of the plug base 14.
`Because
`
`the piercing element 22 is not taller than an upper
`edge height 28 of the plug 13, it is ensured that the
`piercing element 22 only comes into contact with
`liquid-tight
`the separation film 11 after
`the
`connection 21 is produced. Until the time of
`removal of the mixture 4, the opening 5 remains
`closed by a cap 30. The first and the second
`package part 6, 7 are separated until use, for
`example, arranged alongside each other in a folded
`box (not shown). The two package parts 6, 7
`economically consist of plastic. The first material
`2 is a powderlike product 25 and the second
`material 3 is a liquid product 26, while the mixture
`4 is a cosmetic product, especially a cosmetic hair
`product such as a two-component permanent wave
`cosmetic. The screw cap 8 is provided with an
`internal thread 27 of larger diameter than the
`diameter of the container rim 12 of the cuplike
`container 10, while the separation film 11 has a
`diameter such that it is centrally guided by the
`internal thread 27 when placed on the cuplike
`container 10 for the closing (sealing). The removal
`opening 5 is closed by means of a cap 30 until the
`the mixed materials 2, 3. The
`removal of
`separation film 11 is weldable composite material
`of plastic and metal (e.g., aluminum), with the
`metal side arranged toward the piercing element
`22 and it is welded to the container rim 12 by a
`(such as ultrasound
`usual welding method
`welding). This produces a better piercing behavior
`of the separation film 11. When the user brings the
`parts together, a distinct opening or activation
`noise can be heard and thus the activation can be
`determined. This noise is adjustable in its loudness
`by the toughness or brittleness of the plastic
`material. The producing of a predetermined
`breaking zone 18 is a tool-dependent and defined
`situation, while a plug 13 in a locking position is
`dependent on many tolerances. The plug 13 is
`easier to position by its inclined base 14 with
`predetermined breaking zone 18 than a plug which
`has to be placed in a locking position. The plug 13
`with the predetermined breaking zone 18 is a tool-
`related piece as well as a defined use in the bottle
`neck, which is easy to install and has the least
`tolerance dependencies.
`Fig. 2 and 3 show more clearly the cross-shaped
`piercing element 22. Preferably, the piercing
`element 22 is joined to the plug 13 as a single
`piece and is provided as an injection molded
`plastic part.
`In order to bring the two package parts 6, 7
`together to produce a mixture 4 of the two
`materials 2, 3, the first package part 6 is screwed
`onto the second package part 7, so that in the
`course of the screwing on at first a liquid-tight
`connection 21 occurs between the outer side wall
`19 of the cuplike container 10 and the inner side
`wall 20 of the plug 13. Next, the separation film
`11 is pierced by the piercing element 22, which is
`shown in Fig. 4. After this, the container rim 12 of
`the container 10 reaches the upper region 31 of the
`
`combination
`a
`concerns
`invention
`The
`packaging according
`to
`the category of
`the
`preamble of claim 1.
`Such a combination packaging is known from
`DE 198 12 153 Al of the applicant. It has been
`found that the plug 12 according to Fig. 1 cannot
`be placed without problem in its closure position,
`since this is only in a frictional locking position,
`which requires a precise packaging process.
`Nevertheless, during a mass production unwanted
`leakage can occur due to an imprecise fit in the
`locking position.
`It is therefore the problem to be solved by the
`invention to create a combination packaging of
`this category in which the plug during a mass
`production can be easily placed in its closure
`position and unwanted leakage can be prevented
`with certainty. Furthermore, the manual mixing
`process should be possible with a relatively slight
`expenditure of force.
`This problem is solved by the characterizing
`features of claim 1. Further advantageous
`embodiments of the invention will emerge from
`the subclaims.
`The invention is explained more closely by
`means of two sample embodiments. There are
`shown:
`representation a
`sectional
`in a
`Fig. 1
`combination package with a first and a second
`package part as a first sample embodiment;
`Fig. 2 in a perspective view the second package
`part;
`Fig. 3 in a top view a plug with piercing
`element;
`Fig. 4 the combination package of Fig. 1, but in
`a phase of bringing together the two package parts;
`Fig. 5 the combination package of Fig. 4, but in
`a fully assembled condition, and
`Fig. 6
`in a side view a second sample
`embodiment of an assembled combination
`package.
`Fig. 1 shows a combination package 1 for
`packaging a first and a second flowable material 2,
`3, which are kept separate until their use and
`which are mixed together for their use, wherein the
`mixture 4 is removed from a closable removal
`opening 5. The first material 2 is held by a first
`separate package part 6 and the second material 3
`is held by a second separate package part 7. The
`first package part 6 is configured to be screwed
`onto the second package part 7, wherein the first
`package part 6 is configured as an essentially
`rotationally symmetrical screw cap 8 and has at an
`upper outer side 9 the removal opening 5 and at
`the
`inner side a downwardly open cuplike
`container 10, which contains the first material 2
`and is closed liquid-tight by means of a separation
`film 11 at the container rim 12. The second
`package part 7 is closed liquid-tight by a plug 13,
`which is provided with a device 15 arranged at the
`plug base 14 for opening the separation film 11.
`The plug 13 is configured with a sealing collar 32
`so that it closes the second package part 7 firmly
`against axial displacement. The plug base 14 is
`recessed and it has an inclined base 16, which is
`provided
`in
`the edge
`region 17 with a
`predetermined breaking zone 18, which is torn off
`from the container rim 12 when the two package
`parts 6, 7 are screwed together (internal thread

`

`
`
`inclined plug base 14, so that initially the annular
`predetermined breaking zone 18 in this place is
`separated downward from the container rim 14 by
`action of force and then is completely separated
`from the container rim 14, which is shown by Fig.
`5, whereupon the plug base 14 drops downward
`and the separation film 11 is opened entirely on
`top, so that the material 2 from the container 10
`flows onto the material 3 and by manual shaking
`of the combination package 1 a ready to use
`mixture 4 is produced, which can be removed
`through the opening 5 by taking of the cap 30.
`A second sample embodiment of a combination
`container 1.1 is shown in Fig. 6, where the two
`package parts 6, 7 are also joined together as a
`package unit 23 prior to use, and a familiar tear-
`off safety device 24 prevents an unintentional
`mixing of the two materials 2, 3.
