TWO-COMPONENT PACKAGE
The invention refers to a two-component package having a cup, arranged in the neck of the package, to receive the one component and a screw cap which is associated with the neck of the package and has a collar which extends into the cup, the front edge of said collar forming an abutment edge for the separating of the cup in the region of an intended-break line upon the screwing of the screw cap beyond the basic sales position.
A two-component package of this type is known from British Patent 1 083 335. The cylindrical collar which is formed centrally on the cover of the screw cap, and the bottom of the cup which extends in front thereof form the actual receiving chamber for the one component. The intended-break line lies in the region of the bottom edge.
In the basic sales position the front edge is located there. In accordance with the embodiment which is described by way of example, the one component is a powder. The sealing conditions between cup and collar take this suitably into account. Such a package is thrower less suitable for liquid components; for instance, due to the capillary action in the seam between cup and neck a substantial portion of the, mixture would be removed. In addition, there are disadvantages also from a structural standpoint, inasmuch as a sea:L~closure adapted to the conditions of fluids makes the attachment of the cover difficult as a result of the compressing of the enclosed air. Finally, there is also a disadvantage with respect to the discharge of the mixture, inasmuch as the bottom, which is developed as a disk, may possibly place itself in blocking fashion in front of the discharge opening. Finally, the require intended-break lZ351[~1~2 line at the height of the bottom can be produced in practice only in a manner which is expensive with respect to tooling.
Even slight deviations in tolerance can lead to the bottom being separated already upon the placing on ox the screw cap, due -to the lack of any perceptible resistance. The content of -the package may in this way become unusable without this being noted. On the other hand, too hard a threshold of response is disadvantageous for use insofar as unusual screwing forces must be applied. In this way, there may result merely a slight bulging out of the bottom rather than the desired separation.
The object of the present invention is to develop a two-component package of this type in such a manner that, while being easy to manufacture, an arrangement is created which is more favorable for use with respect to the separation.
This object is achieved by the invention in the manner that the intended-break line is formed by an annular step (A) arranged on the cylindrical wall (W) of the cup and extending towards the interior of the cup at a distance (y) from the bottom (2') of the cup.
Other features of the invention provide further advantageous embodiments of the two-component package of the invention.
As a result of this development a two-component package of particularly high value in use is obtained: Due to the fact that the intended-break line Snow arranged at a distance from -the bottom of the cup, the collar no longer exerts a piston-liké compressing action; rather, the collar extends only a very short distance within the cup. This has substantial advantages, particularly also for automatic ~235~
filling. Since the place of intended break is formed by an annular step on the cylindrical wall of the container which extends towards the inside of the cup, the best prerequisites for the separating of the cup are obtained.
'the corresponding forces of the collar act directly from above onto the annular step and therefore in the most stable plane of the cup. The abutment-edge of the collar advantageously rests approximately in alignment with the annular step of the wall of the cup. The upper section of larger cross section of the cup serves in this connection as guide surface for the collar. Different loads can therefore not occur in the region of the intended brealc line. It is furthermore advantageous for the cup to be developed in conical shape, at Least below its annular step. With an annular step which lies at about the center of the height of the cup an advantageous telescopability of the cups is obtained. This is favorable in particular, for storage and naturally also for holding in stock and shipment.
furthermore the fact that the cylindrical surface of the collar is sealed off by a bead lying close to the abutment edge of the collar towards the inner surface of the cylindrical wall of the cup in the basic sales position is also favorable for the attachment. In this way the initial region can be easily moved through, and the sealing action occurs only at the last moment. The compression within the inside of the cup which then takes place is only slight.
The cup itself is securely held within the neck. One embodiment which is advantageous in this respect is characterized by the fact that the cylindrical wall of the cup is held in the neck of the paclcage by a clip step which lies near the mouth of the neck of the package and that the ~2350~2 outer surface of the cylindrical wall of the cup below the clip step is spaced from the inner surface of the neck of the package. The space present there results in advantageous radial flexibility, which favors the seal between collar and cup. On the other hand, the location of the clip step as close as possible to the mouth produces, in this case also, the advantageous effect of the sealing closure only during the last moment of the attachment to -the cup. The screw cap itself is also held in clip attachment on the package. In this respect, the screw cap, in its basic sales position, engages behind a clip shoulder on the neck and the bottom-most region ox the screw thread is formed of individual thread projections which lie, with interruption, one behind the other in the circumferential direction. This interrupted rethread makes it possible to simply press the cap on, the thread projections being jumped over by the internal thread of the screw cap until the clip position is reached. The unilateral support of the flank of the thread which is established already by the rethread favors the tilt-free further screwing on of the cap. The projections may advantageously be of lenticular shape and of different height. This measure additionally favors the pressing on of the screw cap. In the basic sales position which is thereby reached, the abutment edge of the collar is still spaced from the annular step. Intentional further screwing, overcoming the frictional Forces at the sealing bead, is thereupon still necessary in order to enter into the intermediate position which permits the tearing off of the lower section of the cup. In particular for reasons of manufacture, it is advantageous for the clip step and the clip shoulder to be arranged approximately on the same cross _ _ ~L23509Z
sectional plane, In particular, upon the forming of the clip step from the material of the wall of the neck the material which is thereby displaced upward can be used to Norm the clip shoulder (simple displacement of material).
Finally, another advantageous feature is that the annular step is formed by a bridge between two sections of the c~lLndrical wall of the cup which are spaced from each other in radial direction. The corresponding offset in the cylindrical wall can easily be produced by molding. In this connection, there is advantageously taken as basis an amount of offset which corresponds approximately to the thickness of the cylindrical wall. The height of the offset edges, one of which represents the annular step lying on the inside of the cup, determines the resistance to tearing of the bridge material.
Further advantages and details of the object of the invention are explained in further detail below, with reference to an embodiment shown in the drawing, in which:

Fig, 7 is an enlarged view of a portion of Fig. 6, showing particularly clearly the clip step and clip shoulder as well as the sealing bead;
Fig, 8 is a sectional view corresponding to Fig, 6 but with the cup section torn off;
Fig, 9 is a developed view of -the thread of the screw cap, The two-component package contains the one component I
within a cup 2 contained with the package neck 1 and the other component II in the package 3 of larger volume, In order to mix the two components, the cup 2 is torn off, As separating tool there is used a screw cap 4 which simultaneously serves as closure.
The cup 2, which consists of plastic, forms an outwardly directed rim 5 in its upper, substantially cylindrically shaped section. This rim extends over the corresponding end edge 1' of the package nook 1. The rim 5 does not protrude towards the outside and it defines the depth of the suspension of the cup 2. The latter, however, is also additionally secured against falling out, For this purpose, the cylindrical wall W of the cup is secured in the neck of the package by a clip step Sty which lies close to the mouth 6 of the nook 1 of the package. This clip step is formed by an annular rib 7 on the outer surface of the cylindrical wall W of the cup, said annular rib engaging in an annular groove 8 of corresponding shape on the inner surface of the nook 1 of the package, he outer surface of the cylindrical wall W of the cup extends, below the clip step Sty at a distance x from the ~L23S[)92 inner surface of the package neck 1 (see Fig. 7). In this way, the cup 2 can be conveniently introduced. The sealing association is obtained only in the final moment of the insertion attachment, friction occurring between the annular rib 7 and the cylindrical inner surface of the package nook 1. Sue to its closeness to the mouth 6, this region of increased friction is considerably reduced; nor is there any substantial compression within the package upon the introduction of the cup. Even slight compression would not be capable of pressing the cup out again. The clipping forces are correspondingly adapted.
The cup 2 which can be separated by means of the screw cap 4 forms an intended-break line. This line is formed by an annular step A on the cylindrical wall W of the cup lies towards the inside of the cup and extends at a distance y from the bottom 2" of the cup. The abutment edge 9' of a collar 9 of the screw cap 4 which is introduced from above into the cup strikes against said annular step A. The collar commences in the screw-cap cover 10 and is developed as a cylindrical annular wall. The abutment edge extends perpendicular to the longitudinal central axis z-z of the two-eomponent package, which is developed with rotational symmetry.
t its top, the collar 9 is extended by a dispensing tube I which tapers continuously to its free end. Its dispensing opening 12 is kept closed by a stopper 13 which is attached by molding. This is an-original closure.
The abutment edge 9' of the collar is substantially on a line with the annular step A of the cylindrical wall W of the cup. The space y corresponds approximately to two-thirds of the height of the cup 2.

In the basic sales position shown in Fig. 6, the abutment edge 9' of the collar 9 is spaced from the annular step A.
Roy cylindrical surface of the collar 9 is sealed towards the inner surface of the cylindrical wall of the cup 1. Due to its closeness to the mouth 6, this region of increased friction is considerably reduced; nor is there any substantial compression within the package upon the introduction of the cup. Even slight compression would not be capable of pressing the cup out again. The clipping forces are correspondingly adapted.
The cup 2 which can be separated by means of the screw cap 4 forms an intended-break line. This line is formed by an annular step A on the cylindrical wall W of the cup lies towards the inside of the cup and extends at a distance y from -the bottom 2" of the cup. The abutment edge 9' of a collar 9 of the screw cap 4 which is introduced from above into the cup strikes against said annular step A. The collar commences in the screw-cap cover 10 and is developed as a cylindrical annular wall. The abutment edge extends perpendicular to the longitudinal central axis 2-Z of the two-component package which is developed with rotational symmetry.
At its -top, the collar 9 is extended by a dispensing tube 11 which tapers continuously to its free end. Its dispensing opening 12 is kept closed by a stopper 13 which is attached by molding. This is an original closure.
The abutment edge 9' of the collar is substantially on a line with the annular step A of the cylindrical wall W of the cup. The space y corresponds approximately to two thirds of the height of the cup 2.

In the basic sales position shown in Fig. 6, the abutment edge 9' of -the collar 9 is spaced from the annular step A.
The cylindrical surface of the collar 9 is sealed towards the inner surface of the cylindrical wall of the cup in the basic sales position by a bead 14 which lies close to the collar abutment edge 9'. The bead 14, which is developed as an annular rib and extends parallel in space to the abutment edge 9', is formed by an annular rib on the cup

~LZ35~9Z
In the basic sales position shown in Fig. 6, the abutment edge 9' of -the collar 9 is spaced from the annular step A.
The cylindrical surface of the collar 9 is sealed towards the inner surface of the cylindrical wall of the cup in the basic sales position by a bead 14 which lies close to the collar abutment edge 9'. The bead 14, which is developed as an annular rib and extends parallel in space to the abutment edge 9', is formed by an annular rib on the cup
2. The bead 14 lies, insofar as possible, at the height of the abutment edge 9' so that here also the rubbing and sealing closure take place only at the last moment upon the ' attachment of the screw cap, so that the screw cap 4 cannot be pushed off by internal pressure which is formed. In addition, a safety measure is also provided. It consists therein that the screw cap 4 engages, in the basic sales position, behind a clip shoulder 15 on the package neck 1.
The clip shoulder 15 extends approximately on the same cross-sectional plane as the clip step St. The shoulder-forming section of the wall consists, substantially or partly, of the material displaced by the annular groove 8. The mating shoulder 16 on the screw-cap side is an annular rib directed towards the inside of the cap.
In the basic sales position defined by the clip shoulder 15 there is already thread engagement between the screw cap 4 and the package neck 1. The screw cap 4 is simply pushed on. As a result thereof, the lowermost region of the screw thread 17 of the cap 4 comes into engagement with the external thread 18 on the neck of the package. The external thread 18 is seated on a somewhat widened lower section of the package neck 1. In order to facilitate the I
3L~35092 attachment, this lowermost region of the thread consists of individual thread projections 17' lying, with interruption, one behind the other in the circumferential direction.
These projections form a sort of auxiliary thread or rethread It extends over a circumferential region of 360. The full thread then starts. The individual thread projections 17' are approximately of lenticular shape. The lenticular shape results in convex rounding both in the direction of rotation of the screw-cap 4 and in the -transverse direction thereof (direction of the pushing-on of the cap). The distance between them corresponds approximately to the length of one projection. A total of eight projections extend over the periphery. They are of different height so that passage over the external thread 18 is facilitated upon the pushing or screwing on. For screwing on there is the advantage of an association of the screw cap 4 which is free of tilt.
The filling of the two component package is effected as follows:
first of all, the package 3 of larger volume is filled with component II. The height of filling takes into account the depth of insertion of the cup 2. The latter is introduced into the neck of the package in the manner described. The cup 2 is filled with component I.
Thereupon, the screw cap 4, which acts as closure element and tool, is applied. The basic sales position results, due to the clip shoulder 15 which is moved over by the mating shoulder 16 of the screw cap. The flank on the mouth side is correspondingly beveled while the lower flank of the clip shoulder 15 is substantially steeper. At this stage the lowermost region formed by the thread projections 17' of the ~L23~ 2 screw thread 17 is in engagement with the external thread 18. Only upon further turning of the screw cap 4 in the direction indicated by the arrow 20 (see Fig. 3) does the abutment edge 9' of the collar approach the annular step A
of the cylindrical wall W of the cup. The thread engagement between screw cap and package neck 1 is of such length that -the lower portion 2" of -the cup 2 is separated upon the further screwing, i.e. the bridge of material 21, which has the nature of a film hinge, is torn between the two sections 2" and 2''' of the cylindrical wall W of the cup which are spaced apart from each other in radial direction. The separated portion 2" of the cup drops into the package 3.
'rho two components can now be mixed my shaking. In this case the container section 2" which has been torn off serves at the same time as shaking/mixing member. The tight seal between the collar 9 and the section Al'', which now only represents a sealing member, is fully maintained during the shaking.
For the dispensing of the mixture it is then merely necessary to remove the stopper 13.
The offset of the wall sections 2" and 2' " with respect to each other corresponds approximately to slightly more than the thickness of the cylindrical wall W of the cup. The two sections of the cylindrical wall overlap in the region of the bridge of material 21. The amount of the overlap corresponds approximately to one-fifth of the thickness of the cylindrical wall. The cup 2 is of frustoconical shape below the annular step I.
All new features mentioned in the specification and shown in the drawing are essential to the invention, even if they are not expressly included in the Claims.
The clip shoulder 15 extends approximately on the same cross-sectional plane as the clip step St. The shoulder-forming section of the wall consists, substantially or partly, of the material displaced by the annular groove 8. The mating shoulder 16 on the screw-cap side is an annular rib directed towards the inside of the cap.
In the basic sales position defined by the clip shoulder 15 there is already thread engagement between the screw cap 4 and the package neck 1. The screw cap 4 is simply pushed on. As a result thereof, the lowermost region of the screw thread 17 of the cap 4 comes into engagement with the external thread 18 on the neck of the package. The external thread 18 is seated on a somewhat widened lower section of the package neck 1. In order to facilitate the I
3L~35092 attachment, this lowermost region of the thread consists of individual thread projections 17' lying, with interruption, one behind the other in the circumferential direction.
These projections form a sort of auxiliary thread or rethread It extends over a circumferential region of 360. The full thread then starts. The individual thread projections 17' are approximately of lenticular shape. The lenticular shape results in convex rounding both in the direction of rotation of the screw-cap 4 and in the -transverse direction thereof (direction of the pushing-on of the cap). The distance between them corresponds approximately to the length of one projection. A total of eight projections extend over the periphery. They are of different height so that passage over the external thread 18 is facilitated upon the pushing or screwing on. For screwing on there is the advantage of an association of the screw cap 4 which is free of tilt.
The filling of the two component package is effected as follows:
first of all, the package 3 of larger volume is filled with component II. The height of filling takes into account the depth of insertion of the cup 2. The latter is introduced into the neck of the package in the manner described. The cup 2 is filled with component I.
Thereupon, the screw cap 4, which acts as closure element and tool, is applied. The basic sales position results, due to the clip shoulder 15 which is moved over by the mating shoulder 16 of the screw cap. The flank on the mouth side is correspondingly beveled while the lower flank of the clip shoulder 15 is substantially steeper. At this stage the lowermost region formed by the thread projections 17' of the ~L23~ 2 screw thread 17 is in engagement with the external thread 18. Only upon further turning of the screw cap 4 in the direction indicated by the arrow 20 (see Fig. 3) does the abutment edge 9' of the collar approach the annular step A
of the cylindrical wall W of the cup. The thread engagement between screw cap and package neck 1 is of such length that -the lower portion 2" of -the cup 2 is separated upon the further screwing, i.e. the bridge of material 21, which has the nature of a film hinge, is torn between the two sections 2" and 2''' of the cylindrical wall W of the cup which are spaced apart from each other in radial direction. The separated portion 2" of the cup drops into the package 3.
'rho two components can now be mixed my shaking. In this case the container section 2" which has been torn off serves at the same time as shaking/mixing member. The tight seal between the collar 9 and the section Al'', which now only represents a sealing member, is fully maintained during the shaking.
For the dispensing of the mixture it is then merely necessary to remove the stopper 13.
The offset of the wall sections 2" and 2' " with respect to each other corresponds approximately to slightly more than the thickness of the cylindrical wall W of the cup. The two sections of the cylindrical wall overlap in the region of the bridge of material 21. The amount of the overlap corresponds approximately to one-fifth of the thickness of the cylindrical wall. The cup 2 is of frustoconical shape below the annular step I.
All new features mentioned in the specification and shown in the drawing are essential to the invention, even if they are not expressly included in the Claims.
