The packing (1) has a stopper (20) closing a passage opening in a closing position in a fluid-tight manner and releasing the opening in a release position. The opening connects chambers (2, 17) storing components of an adhesive agent. A seal (23) blocks access to a locking unit in a storage position and releases access to a locking element (10) in a stand-by position. The seal is actuated from the storage position to the stand-by position and the stopper is actuated from the closing position to the release position for stirring the components of the agent. An independent claim is also included for a package comprising a multi-component packing and a two-component adhesive agent mixture.

Description

Technical background

The present invention relates to a multi-component packaging for adhesion promoters.

Technical field / state of the art

Although to any multi-component packaging, the present invention and the underlying problem will be explained in more detail below with reference to a two-component packaging for bonding agents.

Adhesion promoters have been used for some time to improve the adhesion, in particular of adhesives and sealants, to surfaces to be bonded or sealed. Adhesion promoters are used in particular where adhesives adhere insufficiently to a substrate. Adhesion promoters are mostly reactive substances and typically form a film on the surface of a substrate to be bonded or sealed and bond to the substrate to develop a sufficiently high adhesive force to act as a primer, i. that they can transmit forces which act on a bonded or sealed substrate to the adhesive or sealant, as well as the joining partner, without the adhesive or sealing compound is destroyed.

In connection with adhesion promoters, a distinction is made between one- and two- or multi-component systems for their storage and application.

In one-component systems, a moisture-reactive compound is mixed with a volatile solvent (VOC) and stored in suitable packaging. When the mixture is applied to a surface to be treated, the volatile solvent evaporates and the humidity causes crosslinking.

A disadvantage of one-component systems, however, the fact has been found that on the one hand, the reaction with the humidity, due to the small amount of water in the air, is relatively slow and is very temperature and humidity-dependent. Therefore, especially in dry winter climates, applications of such adhesion promoters often lead to adhesion problems and adhesive failure. On the other hand, volatile organic solvents (VOC) are coming under increasing pressure and there is a strong desire to eliminate or reduce them.

Two- or multi-component adhesion promoters are characterized in particular by the fact that the components are separated from each other and therefore can be stored for a long time. However, when mixing the components, these two or more components react with each other or one component causes a crosslinking reaction of the other component. It is thus intrinsic to the system that such two- or multi-component adhesion promoters can only be stored for a very short time after mixing the components before application, without losing the adhesion-promoting function with them. When mixing two or more components, it is also important that they are mixed in the correct mixing ratio.
If the two or more components are mixed during the application, there is a risk that the mixture will not occur at certain points or in a wrong mixing ratio, which entails the risk that adhesion of components to the treated surface will be insufficient given is. However, this is not tolerable, especially in the area of safety-relevant components, for example in windshields of vehicles.

An example of a two-component packaging is in the EP 0 536 841 B1 described.

Presentation of the invention

It is therefore an object of the present invention to provide an improved multi-component packaging for adhesion promoters in which an application of a component on the surface to be treated without prior mixing with at least one of the further component is excluded and in which an unwanted mixing of the two or more components is excluded.

According to the invention, this object is achieved by a multi-component packaging having the features of patent claim 1 and / or by a pack having the features of patent claim 15.

Accordingly, a multi-component package for a primer, consisting of at least a first and second component. The multi-component packaging in this case has a first chamber for receiving the first component of the adhesion promoter, wherein the first chamber has a removal opening for removal of the adhesion promoter. Furthermore, the multi-component packaging has a closure means which closes the removal opening in a fluid-tight manner. The multi-component package is further formed with a second chamber for receiving the second component of the adhesion promoter. In addition, the multi-component packaging is provided with a shut-off means, which closes fluid-tightly in a closed position connecting the first and second chamber passage opening and releases in a release position. A seal of the multi-component packaging obstructs access to the closure means in a storage position and releases the access to the closure element in a standby position, wherein actuation of the seal from the storage position to the ready position at the same time the shut-off from the closed position to the release position for mixing the first and second component actuated.

Furthermore, a pack with the multicomponent packaging according to the invention and with a first and second component, the components being suitable for combination to form a coupling agent.

The idea underlying the present invention is that for applying the adhesive, the closure means must be removed from the removal opening, the access to the closure means to remove this, however, is blocked by the seal as long as this is in the storage position located. Accordingly, in particular a user, the seal must first spend from the storage position in the ready position to get to the closure element. The seal is in this case coupled to the blocking means that actuation of the seal from the storage position into the standby position simultaneously requires actuation of the blocking means from the closed position into the release position. If the blocking means is now in the release position, the through opening connecting the first and second chambers is at least partially open, so that the first and second components at least partially, if possible completely, mix and the two components can react with each other in the correct mixing ratio. This ensures that the first and second components are applied only in the mixed state on a surface to be treated. This ensures adequate adhesion between the surface to be treated and adhesives or sealants applied to it. Thus, the inventive multi-component packaging, especially in the field of manufacturing safety-related components is well usable.

In the dependent claims are advantageous embodiments, improvements and developments of the specified in claim 1 multi-component packaging and the package specified in claim 15.

In the present case, a "chamber" is understood to mean a volume together with a wall, wherein the wall encloses the volume almost completely or completely.

The term "release" of the passage opening in the present case is also understood to mean only a partial release.

According to a preferred refinement, an upsetting section is provided between the passage opening and the second chamber and the closing means is inserted as a stopper which is inserted into the passage opening in its closed position, a counter surface arranged towards the second chamber pushing the stopper out of the passage opening during upsetting of the upsetting section and thus spends this in the release position, wherein the upsetting of the compression portion associated with the actuation of the seal from the storage position in the standby position. Such a mechanism for actuating the shut-off from the closed position to the release position for releasing the passage opening can be produced easily and comparatively reliable.

According to a further preferred embodiment of the invention, the seal is substantially envelope-shaped, wherein the seal from the storage position in which it surrounds the closure element inaccessible, in particular for a user's hand, in the standby position in which it is the closure element in particular for the hand of the User accessible, movably provided. By means of such a shell-shaped seal can be ensured in a simple manner that the user does not get to the closure element with his hand in the storage position of the seal.

According to a further preferred embodiment of the invention presses when moving the seal from the storage position to the standby position the same for upsetting the upsetting portion on the closure element or the first chamber. Thus, the movement of the seal from the storage position into the ready position with the actuation of the shut-off means from its closed position in its release position can be coupled in a mechanically simple manner.

According to a further preferred embodiment of the invention, the closure means, the removal opening, the first chamber, the passage opening, the compression portion and / or the second chamber in the compression direction substantially successively - and preferably in this order - lying on an axis and / or substantially formed symmetrically or rotationally symmetrical with respect to the axis. Thus, it is easily ensured that pressing the seal on the closure element or the first chamber when moving it from the closed position to the standby position also leads to a compression of the swaged portion, wherein the applied compressive force acts substantially along the axis.

According to a further preferred development of the invention, the seal is provided movably substantially along the axis. Thus, the seal can be easily moved from the storage position to the standby position along the axis.

Alternatively, the seal could also be accordion-like, wherein it is then set at one end, in particular at the second chamber and is provided to be movable at its other end along the axis, wherein a concertina-shaped portion connects the one and the other end.

According to a further preferred embodiment of the invention, the seal is provided on the outside of the second chamber guided guided. In this way, the mobility of the seal along the axis can be easily provided.

Both in the case that the seal has a concertina-shaped portion, as well as in the case that the seal is provided outwardly guided guided on the second chamber, the user is denied, the multi-component packaging in the region of the swage portion or seen from this further towards the closure element with its grab a hand and press the seal with the other hand from the storage position to the standby position, whereby a simultaneous actuation of the blocking means would be avoided from its closed position to the release position.

According to a further preferred development of the invention, the seal has a substantially hollow cylindrical portion and an at least partially closing end face portion, wherein the hollow cylindrical portion in the storage position of the seal at least the closure means, the removal opening, the first chamber, the through hole and the compression portion accommodates in itself and the front-side portion having an opening for a passage of the closure element when moving the seal from the storage position to the standby position. By "hollow cylindrical" is meant in particular hollow circular cylindrical. The hollow cylindrical portion and the frontal portion together prevent access in the storage position of the seal to the closure element for a user's hand.

According to a further preferred development of the invention, the opening in the end-side section has a diameter which is smaller than that of the closure element, wherein the seal has an elastic material at least in the region of the opening, wherein the pressure required for expanding the elastic material on the closure element exceeds the necessary pressure for upsetting the compression portion. Thus, it is ensured that an upsetting of the swaged portion occurs before the opening in the frontal section is pushed over the closure element and thus releases access to the closure element. The pressure required to expand the elastic material and the pressure required to compress the swaged portion act against each other (vector view of the compressive forces). The upsetting of the upsetting portion occurs when the pressure on the closure member, the pressure for compressing the Upset portion, so the resistance of the compression portion against a compression of the same exceeds.

According to a further preferred development of the invention, the removal opening on the outside has a projection which is arranged on the side facing the first chamber of the closure element and has approximately the diameter of the closure element, wherein the frontal portion engages behind the projection with respect to the closure element in the standby position. Thus, it is advantageously ensured that the seal remains in the ready position and is not accidentally moved back into the storage position, which could adversely affect a handle of the multi-component packaging.

According to a further preferred embodiment of the invention, the opening in the frontal section is closed by means of a sticker in the storage position, wherein the necessary pressure for releasing the sticker on the closure element exceeds the pressure for upsetting the compression section. Again, the above applies to the respective necessary pressures accordingly. Such a sticker is very easy to apply. In addition, the sticker may also contain information about the contents of the multi-component packaging. The sticker would thus advantageously have a dual function.

According to a further preferred embodiment of the invention, the opening in the frontal section is closed by an insert in the storage position, which is coupled to the edge of the opening by means of a predetermined breaking point, wherein the necessary for a breaking of the predetermined breaking point pressure on the closure element the necessary pressure for Upsetting of the upsetting section exceeds. Again, the above applies in each case to the necessary pressures. Such an insert can be advantageous in one piece, in particular in an injection molding process, produce with the seal.

According to a further preferred embodiment of the invention, in the storage position, a ring of an elastic material between the front-side portion and the first chamber is provided, which has a diameter which is smaller than that of the first chamber, wherein the pressure necessary for an expansion of the ring on the first chamber exceeds the necessary pressure for upsetting the compression portion. Again, the above applies to the respective pressures said accordingly.

According to a further preferred development of the invention, the multi-component packaging has a mechanism for preventing an automatic movement of the seal from the ready position to the storage position. Thus, it can be ensured that the seal remains in the standby position during handling of the multi-component packaging.

According to a further aspect, the present invention relates to a pack which consists of a multicomponent packaging according to the invention and a two-component adhesion promoter composition. The first component K1 contains at least one reactive compound RV1. The second component K2 contains at least one compound VB which is able to react with the reactive compound RV1 of the first component or causes crosslinking of the reactive compound RV1 of the first component. The two components K1, K2 of the two-component adhesion promoter composition are stored separately in different chambers of the multi-component packaging.

As a two-component adhesion promoter or adhesion promoter compositions can be implemented very chemically diverse.
In a first variant, the compound VB is a compound with which the reactive compound RV1 of the first component can govern.
For example, the reactive compound RV1 of the first component K1 is an epoxy resin having at least two epoxide groups, in particular a bisphenol A digylcidyl ether or a bisphenol F digylcidyl ether, and the compound VB of the second component K2 represents a polyamine or a polymer kaptan. The epoxy-chemistry expert is well aware of possible epoxy resins, polyamines and polymercaptans as well as the details of the formulation of the respective components.
Substance names beginning with "poly", such as polyol, polymercaptan, polyamine or polyisocyanate, refer in the present document to substances which formally contain two or more of the functional groups occurring in their name per molecule.

Furthermore, the reactive compound RV1 of the first component K1 may be a polyisocyanate or an isocyanate group-terminated polyurethane prepolymer and the compound VB of the second component K2 may be a polyamine or a polymercaptan or a polyol. The polyurethane specialist is well-known for possible polyisocyanate, isocyanate-terminated polyurethane prepolymers, polyamines, polymercaptans and polyols, as well as the details of the formulation of the respective components.

In a second variant, the compound VB is a catalyst or initiator. For example, the compound is a radical generator, for example an organic peroxide, a peracid or a perester, while the reactive compound RV1 is a free-radically polymerizable mono- or oligomer, for example a (meth) acrylic acid or (meth) acrylic acid ester or styrene.

In particular, the reactive compound RV1 of the first component K1 is a silane or a titanate.
In the present document, "silane" refers to an organosilicon compound which has at least one, in particular at least two, alkoxy group or acyloxy group which is or are bonded directly to a silicon atom via an oxygen-silicon bond and which carries at least one substituent, which is bonded via a silicon-carbon bond to the silicon atom, and which optionally has a functional group which is selected from the group comprising oxirane, hydroxy, (meth) acryloxy, amino, mercapto and vinyl group. A silane can also contain several silicon atoms.

Way to carry out the invention

Fig. 1A shows a cross-sectional view of a multi-component package 1 according to an embodiment of the present invention.

The multicomponent packaging 1 has a first chamber 2 for receiving a first component K1 of a bonding agent, for example a silane or a titanate. The first chamber 2 is composed of a wall 3 and a volume 4, which is circumferentially enclosed by the wall 3. In the volume 4, the first component of the adhesion promoter is added.

At one end of the chamber 2, a collar 5 adjoins, which is composed of a wall 6 and a discharge opening 7, which is circumferentially enclosed by the wall 6. The collar 5 has a thread 8 which engages with a mating thread 9 of a closing element 10 designed as a closure cap, which is screwed onto the collar 5. The closure element 10 closes the removal opening 7 in a fluid-tight manner.

Alternatively, the closure element 10 could also be formed, for example, as a tear-off sticker, which closes off the removal opening 7 in a fluid-tight manner.

Furthermore, the multi-component packaging 1 has a passage region 11, which is composed of a wall 12 and a passage opening 13, the wall 12 surrounding the passage opening 13 circumferentially.

A compression section 14, which according to the present exemplary embodiment consists of a foldable wall 15 and a volume 16, preferably adjoins the passage region 11, wherein the volume 16 is surrounded circumferentially by the wall 15. At the compression portion 14 is followed by a second chamber 17, which is composed of a wall 18 and a volume 19, which is circumferentially surrounded by the wall 18. The volume 19 receives a second component K2 of the adhesion promoter, for example water or an aqueous acid. In this case, the swaging section 14 is connected to the second chamber 17 via a further passage region 16a. The further passage region 16a is composed of a wall 16b and a volume 16c, which is circumferentially surrounded by the wall 16b.

The passage opening 13, which connects the volume 4 of the first chamber 3 with the volume 16 of the compression portion 14 or with the volume 19 of the second chamber 17, is in Fig. 1A sealed fluid-tight with a shut-off device 20 designed as a stopper. The plug 20 has a first portion 21, which is resiliently pressed into the through-hole 13, and a second portion 22, which extends from the first portion 21 in the direction of the second chamber 17.

The multi-component packaging 1 also has a seal 23, which is composed of a hollow cylindrical section 24 and an end-side section 25 closing this at its one end 24a. The end-side section 25 has an opening 26, which faces the closure element 10. The hollow cylindrical portion 24 encloses together with the front-side portion 24 in the in Fig. 1A illustrated storage position of the seal 23 the following parts: the closure element 10, the removal opening 7, the first chamber 2, the passage area 11, the upsetting portion 14, the further passage area 16a and the second chamber 17 in sections. The parts 10, 7, 2, 11, 14, 16a, 17 are successively arranged in the above order on the axis 27 and preferably formed rotationally symmetrical with respect to this.

According to the present embodiment, the hollow cylindrical portion 24 of the seal 23 is movably supported on the second chamber 17, preferably on its wall 18, along the axis 27.

The wall 18 is formed with a hook-shaped portion 28 and the hollow cylindrical portion 24 of the seal 23 with a corresponding hook-shaped counter portion 29, so that a detachment of the seal 1 in the direction indicated by the arrow 30 is prevented.

Alternatively, the hollow cylindrical portion 24 of the seal 23 in the region of the hook-shaped portions 28, 29 fixedly connected to the wall 18 of the chamber 17, in which case the hollow cylindrical portion 24 should be at least partially accordion-shaped, to a mobility of the frontal portion 25 with respect to ensure the closure element 10.

Preferably, the multi-component packaging 1 also has an opening inspection 30a. This may, for example, comprise a ring 30b, which is fastened to the wall 18 of the chamber 17 behind the other end 30c of the hollow cylindrical section 24, opposite the end-face section 25, by means of a predetermined breaking point, in particular legs 30d. In Fig. 1A the ring 30d prevents movement of the seal 23 in the direction 31.

A tab 30e is preferably attached to the ring 30b, by means of which the user can only irreversibly tear off the ring 30b from the wall 18, so that it is evident in later use that the first opening of the multi-component packaging 1 has already taken place. A movement of the seal 23 in the direction 31 is now released.

The above in connection with Fig. 1A described construction of multi-component packaging also applies to the embodiments according to the Fig. 2A to 4B to and therefore will not be explained for this.

In the embodiment according to the Fig. 1A and 1B is now the opening 26 in the frontal portion 25 of the seal 23 with respect to the axis 27 in the radial direction elastic and formed with a diameter D1 smaller than the diameter D2 of the cap 10.

Now brings a user in the direction of arrow 31, a force on the seal 23, so the edge portion 32 of the opening 26 presses the upper side on the closure element 10. If the pressure is correspondingly large, then there is a compression of the swaged portion 14, wherein fold the walls 15 of the swaging portion 14 as shown in FIG Fig. 1B shown. The compression movement causes the portion 22 of the plug 20 comes into contact with a mating surface 33, which is formed according to the present embodiment by the wall 16a, which has a smaller diameter than the portion 22 of the plug 20. This mating surface 33 now presses the plug 20 from its closed position, see Fig. 1A , in its release position, see Fig. 1B , If the plug 20 is now in its release position, the first component in the chamber 4 mixes with the second component in the chamber 19. The two components can now react with each other.

If the upset section 14 is completely compressed, ie further movement of the closure element 10 in the direction of the arrow 31 is no longer possible, the user still has to slightly increase the pressure in the direction of the arrow 31, whereupon the edge region 32 of the opening 26 then elastically expands and slips over the closure element 10 and a projection 34 of the wall 6 of the collar 5 and the projection 34 engages behind, as in Fig. 1B shown. The projection 34 is preferably provided adjacent to the closure element 10 and between this and the first chamber 2.

By engaging behind the projection 34 by the edge portion 32 of the seal 23 in the standby position, see Fig. 1B , it is prevented that this automatically again, for example, during the handling of the multi-component package 1 by the user in an application of the bonding agent, for example, on a windshield, moved in the direction 30 and thus hindering application of the bonding agent. Preferably, the edge region 32 of the opening 26 is provided with a slope 35 which cooperates with a bevel 36 which is provided at the opening 26 facing the end of the closure element 10. The bevels 35, 36 have, for example, an angle of approximately 30 to 70 degrees to the longitudinal direction. Thus, it is possible to form the edge region 32 with a comparatively low elasticity, which advantageously counteracts a widening of the edge region 32 necessary for a return movement of the seal 23 in the direction 30 over the projection 34, at the same time requiring the user to move the seal 23 remains relatively low in the direction 31 from the storage position to the ready position.

Only now is it possible for the user to grip the closure element 10 in order to unscrew it. At this time, however, a good mixing of the first and second components (and thus the start of the reaction of the two components) has already taken place. After unscrewing the closure element 10, the user can now apply the adhesion promoter, for example on a windshield of a vehicle.

Fig. 2A and 2 B show a multi-component package 40 according to another embodiment of the present invention.

There are only the differences from the embodiment according to the following Fig. 1A and 1B explained because there is a fundamental agreement between the two embodiments.

In the embodiment according to the Fig. 2A and 2 B the opening 26 is formed with a diameter D1 which is greater than the diameter D2 of the closure element 10.

Furthermore, a sticker 41 is glued to the end face 25 of the seal 23, which covers the opening 26. The adhesive effect of the adhesive 42, which connects the sticker 41 with the end face 25, is provided such that the sticker 41 only dissolves when the pressure on the sticker 41, which when moving the seal 23 from the storage position, see Fig. 2A , in the ready position, see Fig. 2B is exerted on the latter by means of the closure element 10, the pressure required for upsetting the compression portion 14 exceeds.

Consequently, therefore, first a compression of the upsetting portion 14 takes place, whereupon, if the pressure is still slightly increased to the seal 23, the sticker 41, as in Fig. 2B shown detached from the end face 25, whereupon the seal 24 is pushed over the closure element 10, and the latter is thus accessible for the user's hand to unscrew.

Preferably, the hollow cylindrical portion 24 of the seal 23 on the inside a further hook-shaped counter portion 43, which is arranged such that it in the standby position, see Fig. 2B , the hook-shaped portion 28 engages behind and thus prevents an automatic release of the seal 23 in the direction 30, as already explained above in connection with the projection 34.

Preferably, the label 41 may also be printed on the outside at the same time as information relevant for the multi-component packaging, for example information about the chemical composition of the content.

In Fig. 3A and 3B a multi-component package 50 according to yet another embodiment of the present invention is shown.

Again, only the differences from the embodiment according to the Fig. 1A and 1B explained because there is a fundamental agreement between the two embodiments.

In the embodiment according to the Fig. 3A and 3B , in the storage position of the multi-component packaging 50, the opening 26 is closed with an insert 51. The opening 26 has a diameter D1, which is larger than the diameter D2 of the closure element 10 is formed. The insert 51 is connected by means of a predetermined breaking point 52 around with the edge region 32 of the end face 25.

Preferably, the seal 23 together with the insert 51 and the predetermined breaking point 52 is produced as one piece, in particular by injection molding.

The predetermined breaking point 52 is designed in such a way that it only breaks when the pressure which is exerted on the insert 51 on the inside by means of the closure element 10 exceeds the pressure required to compress the compression portion 14. Accordingly, therefore, the compression portion 14 is initially compressed when moving the seal 23 in the direction 31. If then the pressure on the seal 23 is increased even further, the predetermined breaking point 52 breaks and the insert 51 comes off the opening 26 and thus releases it, so that the seal 23 can be guided over the closure element 10, so that the latter for a user's hand becomes unscrewable.

Preferably, the wall 18 of the chamber 17 has a further hook-shaped portion 53, see Fig. 3A on the outside on which such is arranged that the hook-shaped counter portion 29 engages behind the hook-shaped portion 53 in the standby position and thus prevents an automatic release of the seal 23 in the direction 30, as already explained above in connection with the projection 34 (in Fig. 3B not shown).

In the Fig. 4A and 4B a multi-component package 60 according to yet another embodiment of the present invention is shown.

Again, only the differences from the embodiment according to the Fig. 1A and 1B explained in more detail.

In the embodiment according to the Fig. 4A and 4B the opening 26 in the end face 25 of the seal 23 is formed with a diameter D1 greater than the diameter D2 of the closure element 10.

A ring 61 made of elastic material, in particular plastic, is integrally formed on the edge region 32 of the front side 25 on the inside. This ring 61 extends in the storage position of the seal 23, see Fig. 4A , from the edge region 32 along the axis 27 and abuts against the first chamber 2. For this purpose, the first chamber 2 has a greater extent in the radial direction relative to the axis 27 than the inner diameter D3 of the ring 61.

The rigidity of the ring 61 is dimensioned such that the pressure necessary for expanding the ring, which by means of the second chamber 17 to the end of the ring 61 facing it when the seal 23 is actuated from the storage position, see Fig. 4A , in the ready position, see Fig. 4B is applied, the pressure necessary for upsetting the compression portion 14 exceeds.

Thus, if a suitable pressure is exerted on the seal 23 in the direction 31, the upsetting portion 14 is initially compressed. If the pressure is then increased further, the ring 61 slips over the second chamber 17 and thus allows the seal 23 to move past the closure element 10, so that this, as in FIG Fig. 4B shown, is exposed and thus accessible for a user's hand to unscrew.

Preferably, the ring 61 in the ready position of the seal 23, see Fig. 4B , a protruding portion 62, which tapers behind the first chamber 2 and thus counteracts an automatic release of the seal 23 in the direction 30. Incidentally, the frictional resistance acting between the ring 61 and the wall 3 of the first chamber 2 also prevents the seal 23 from automatically loosening in the direction 30, so that the effect of the protruding portion 62 is an improvement, which may or may not be dispensed with ,

Of course, the embodiments according to the Fig. 1A to 4B be combined with each other as desired. In particular, the illustrated mechanisms for preventing self-loosening of the seal 23 in the direction 30 can be arbitrarily combined with each other. Furthermore, it is clear to those skilled in the art that the embodiments in which the first component K1 in the first chamber 2 and the second component K2 in the second chamber 17 are equivalent to those embodiments in which the first component K1 in the second chamber 17 and the second component K2 are arranged in the first chamber 2.
The invention is not limited to the specific structure of a multi-component package illustrated in the preceding figures.

For example, more than two chambers, for example, three or four chambers may be provided, each containing different solid, liquid and / or gaseous components.
