Assembly comprising a foil pack and a dispensing device and foil pack

Abstract

An assembly can be used for packaging chemical compounds. The assembly includes a foil pack for storage of a one-component or multicomponent compound, and a dispensing device for the foil pack. The foil pack has at least one elongated foil bag designed to be non-rigid, and one rigid head part having at least one fastening portion for one end of the foil bag and an outlet opening for discharge of the compound, where the dispensing device has at least one receptacle for pushing in the at least one film bag. The at least one elongated foil bag has, in a filled condition, the form of a truncated cone, the diameter of which narrows in the direction of a longitudinal axis, starting from the respective fastening portion.

Description

(1) Further features and advantages will become apparent from the description hereinafter of a preferred embodiment on the basis of the attached drawings, wherein:

(2) FIG. 1 shows a sectional view of an inventive assembly before the foil pack is pushed into the dispensing device;

(3) FIG. 2 shows a sectional view of the assembly from FIG. 1, wherein the foil pack is partly pushed into the dispensing device, and

(4) FIG. 3 shows a sectional view of the inventive assembly in an end position, in which the foil pack has been pushed completely into the dispensing device.

(5) FIGS. 1 to 3 show an inventive assembly 10, which is provided with a foil pack 12 for storage of in this case a two-component compound and with a dispensing device 14 for foil pack 12.

(6) Foil pack 12 comprises a first filled foil bag 16 as well as a second, filled foil bag 18 disposed laterally alongside first foil bag 16, which bags are used to retain the components of the two-component compound in storage separately from one another. Foil bags 16, 18 themselves are elongated and (without contents) are designed to be intrinsically non-rigid.

(7) Furthermore, foil pack 12 comprises an intrinsically rigid head part 20, which has a first fastening portion 22, on which one end 24 of first foil bag 16 is fixed. A second fastening portion 26 for one end 28 of second foil bag 18 is provided laterally alongside first fastening portion 22. Both foil bags 16, 18 are undetachably fixed on head part 20. Beyond this, two straight-through ducts 30, 32 are formed in head part 20, each of which joins one of the foil bags 16, 18 with a common outlet opening 34. A mixer attachment (not shown) is usually screwed onto this.

(8) Both foil bags 16, 18 have the form of a truncated cone, the diameter of which narrows in the direction of a longitudinal axis L of the foil bags 16, 18, starting from the respective fastening portion 22 or 26. In this connection, both the cone angle .sub.1 of first foil bag 16 and the cone angle .sub.2 of second foil bag 18 lie in the range of 0.1 to 10, especially of 2 to 6. In the shown embodiment, both cone angles .sub.1 and .sub.2 are approximately 4, as is evident in FIG. 1, in which, for space reasons, the angles of inclination .sub.1/2 and .sub.2/2, which indeed correspond exactly to the respective half cone angle, are indicated instead of the actual cone angles .sub.1 and .sub.2.

(9) First foil bag 16 has a greater diameter along its entire length than does second foil bag 18, as can be inferred from the figures. Consequently, first foil bag 16 has a larger volume of the two-component compound, whereby this component predominates in the finish-mixed compound. In principle, the mixing ratio of the two-component compound is adjustable via the volume or diameter ratio of foil bags 16, 18.

(10) Dispensing device 14, which is shown only partly in the figures (without illustration of the actual dispensing mechanism, for example in the form of one or more plungers), has a first receptacle 36 for first foil bag 16 as well as a second receptacle 38, disposed laterally alongside it, for second foil bag 18. Both receptacles 36, 38 have a frustoconical inner circumferential wall 40 and 42 shaped to be complementary to the associated foil bag 16, 18 and respectively tapering conically in the direction of longitudinal axis L. The cone angles .sub.1, .sub.2 of these internal circumferential walls 40, 42 correspond to those of the respectively associated foil bags 16, 18.

(11) FIG. 2 shows a middle position, in which foil pack 12 is partly pushed approximately halfway into dispensing device 14. By virtue of the frustoconical shape both of foil bags 16, 18 and of receptacles 36, 38, there is no need here to provide a joint gap, as is known for conventional plain cylindrical foil bags. In addition, pushing in is simpler because of the inclination of the participating walls.

(12) Finally, FIG. 3 illustrates the end position 16, 18, in which both foil bags are completely pushed into the respective associated receptacle 36, 38. In this completely pushed-in condition, both foil bags 16, 18 bear with full surface contact on the respective internal circumferential wall 40 or 42 of the associated receptacle 36, 38.

(13) By virtue of this complete support or full surface contact in the end position, no matching of the mechanical properties is needed in the inventive embodiment, and so the two foil bags 16, 18 may be made from foils with different mechanical properties.
