Description

BRIEF DESCRIPTION OF THE DRAWING

(1) Further features and advantages will become obvious from the description hereinafter of two preferred embodiments on the basis of the attached drawings, wherein:

(2) FIG. 1 shows a side view of an inventive assembly with a partly emptied film bag;

(3) FIG. 2 shows a side view of the assembly from FIG. 1 with completely emptied film bag; and

(4) FIG. 3 shows a side view of a film package inserted in a discharge device according to a further embodiment of the invention with partly emptied film bag.

DETAILED DESCRIPTION

(5) FIGS. 1 and 2 show an inventive assembly 10, which is provided with a film package 12 for storing a chemical mass, such as, for example, a sealing mass, a mortar, a coating mass, a dye, a foam precursor, an adhesive or a lubricant. Furthermore, assembly 10 comprises a discharge device 14 for film package 12.

(6) Film package 12 is provided with a filled film bag 16, which is used for storage of one or more components of the said mass. Film bag 16 is elongated and (without contents) is designed to be inherently non-rigid. Furthermore, film package 12 comprises an inherently rigid carrier part 18, on which one axial end, here the outlet end 20, of film bag 16 is fixed. Carrier part 18 is provided with an outlet opening 22 for the mass stored in film bag 16, wherein outlet opening 22 is disposed centrally in carrier part 18 and extends over its entire height. A mixer attachment, which is not shown in the figures, may be coupled with outlet opening 22.

(7) Via a circumferential joint 24 disposed on the outside of carrier part 18, carrier part 18 is joined to tubular film bag 16 and projects at least partly into film bag 16.

(8) Moreover, carrier part 18 is provided in a rim region 26 facing film bag 16 with a receiving groove 28, which is formed as a circumferential annular groove. This receiving groove 28 starts from the end face 30 of carrier part 18 facing the inside of film bag 16 and extends over approximately two thirds of its height.

(9) For the purpose of emptying, film package 12 is inserted in a receptacle 32 of discharge device 14, and a piston 34 is disposed displaceably in receptacle 32.

(10) Piston 34 is likewise provided with a circumferential groove 36, which starts from an end face 38 of piston 34 that bounds receptacle 32 and faces film bag 16, and which is disposed in a shell region 40 of piston 34 that faces an inner circumferential wall 42 of receptacle 32. Receiving groove 36 is also formed as a circumferential annular groove.

(11) Both receiving grooves 28, 36 are used for receiving accumulated film sections 44, which are formed during discharging of film bag 16 by displacement of piston 34 in receptacle 32 while film bag 16 is still being emptied. FIG. 1 shows the partly emptied state of film bag 16.

(12) Therein the two receiving grooves 36 and 28 of piston 34 and of carrier part 18 respectively are constructed to be almost equally broad and, just as the respective heights of receiving grooves 28, 36, are selected and matched to one another in such a way that they are able to receive the accumulated film sections 44 of the completely emptied film bag 16, so that complete emptying of film bag 16 is achieved in the end position of piston 34 shown in FIG. 2.

(13) Alternatively to the shown configuration, in which both discharge device 14 and film package 12 are provided with a receiving groove 36 and 28 respectively for accumulated film sections 44, discharge device 14 naturally can also be used with a conventional film package, just as film package 12 may also be used in a conventional discharge device. The decisive aspect is then merely that the width or height of what is then the single receiving groove is selected such that it is able to receive the accumulated film sections of the entire completely emptied film bag.

(14) FIG. 3 shows an alternative configuration of an inventive film package 12, wherein, hereinafter, like parts are denoted by like reference symbols and only the differences relative to the embodiment described in the foregoing are discussed.

(15) Film package 12 according to FIG. 3 is used in a conventional discharge device 14, which is provided with a simple dish-like piston 34 without receiving groove. This discharge device 14 is known in itself, and so it will not be discussed further here.

(16) Film package 12 corresponds in its upper region in FIG. 3 to that of FIGS. 1 and 2 and is additionally provided at end 46 of film bag 16 facing piston 34 with a further carrier part 48. This also has available a receiving groove 50, which is provided in a rim region 52 of the carrier part facing film bag 16 and starts from an end face 54 of carrier part 48 facing the inside of film bag 16. Carrier part 48 also projects partly into film bag 16 and is joined thereto via a joint 56 disposed on the outside of carrier part 48.

(17) In film package 12 according to FIG. 3, therefore, a carrier part 18 or 48 is provided at the two axial ends 20, 46 of elongated film bag 16 with a receiving groove 28 or 50 respectively. Therein especially the heights of the two receiving grooves 28, 50 are matched to one another in such a way that they are able to receive the accumulated film sections 44 of the completely emptied film bag 16 (not shown), so that once again complete emptying of the film bag 16 is achieved in an end position of piston 34.
