RECHARGEABLE CONTAINER FOR THE ASSIGNMENT OF AN EXTENSIVE MASS. SPECIFICALLY ADHESIVE MASS Technical Field The invention relates to a container for the transfer of an extensible mass, especially adhesive mass, with an inner socket containing the extensible mass, disposed removably in an outer sleeve and open at least on one side, which has a piston that can be crossed by a threaded spindle and fixing means for its mooring in the outer sleeve. The threaded spindle and the piston form cooperation means for the transfer of the extensible mass. By the rotary activation of the threaded spindle that impinges on the internal thread of the piston by means of the activation element disposed outside the outer sleeve, especially of a knurled nut operable by hand, the extensible mass is movable in the axial longitudinal direction in the container when there is a relative stationary position of the outer bushing and the inner bushing with each other. STATE OF THE ART A refillable container is known as a refillable cartridge for glue pencils in DE 41 16 581. The reusable outer sleeve contains a threaded spindle, which also rotates when a knurled nut disposed at the closed end of the container is rotated. A replacement part, that is to say, the inner bushing, contains the piston with the internal thread, in which the pink spindle engages, to move the piston in the direction of the open end, opposite the knurled nut of the container in the shape of tube and in this way press the adhesive mass outwardly from the open end. The known container is provided as a rechargeable container for a sticking pencil provided for sticking paper. To fill the container, proceed as follows. The knurled nut is turned until it does not engage in the internal thread of the piston. The empty inner bushing is then removed together with the piston out of the outer bushing. A new inner bushing filled with adhesive is then inserted and contains a piston with central threaded hole inside the open end of the outer bushing until the threaded spindle securely connected to the outer bushing strikes its open end on the internal thread of the piston. By turning the knurled nut, the threaded spindle is screwed into the internal thread of the piston and into the adhesive. In this case, the inner sleeve moves further inside the outer sleeve until a final position is reached. Projections in the form of dots placed on the inner wall of the outer bushing fit there in cavities in the form of corresponding points in the outer wall of the inner bushing. This retaining connection fixes the inner bushing inside the outer bushing, so that the inner bushing can neither move in the longitudinal direction nor rotate with respect to the outer bushing. For the removal of the adhesive mass, the knurled nut is then rotated in the opposite direction, so that the piston moves towards the open end of the inner sleeve and the adhesive is pressed outwards. In the known container, the costly helical movement of time when a new cartridge is used is a drawback. Therefore, the user is often not prepared to equip the empty container with a new rechargeable cartridge, but the container as a whole is discarded and a complete new container is used. Therefore, the intended purpose with the known container of waste reduction is often not achieved. SUHARIO Therefore, the invention has the task of considerably facilitating the replacement of the inner sleeve in a container of the type mentioned at the beginning. This task is solved according to the invention in that the threaded spindle is fixed in a position that passes through the piston rotatably in the inner sleeve and has a connection part., which is projected especially from the inner sleeve, which can be coupled-releasably secured in a corresponding connection part of the activation means. Therefore, in opposition to the aforementioned state of the art, the threaded spindle is not a part of the outer sleeve, but a part of the inner sleeve and, consequently, the part to be replaced. Therefore, when replacing an empty inner bushing by means of an inner bushing filled with the extendable mass, a helical movement is not necessary. After removing the empty inner sleeve, simply insert the new inner sleeve easily into the outer sleeve until the connection parts of the outer sleeve and the inner sleeve are connected to each other. This very rapid and simple replacement of the inner sleeve leads to an essentially reduced amount of waste, although the part to be replaced and, therefore, the part that is used only once contains more material than in the state of the art . Then the consumer, due to the simplified replacement of the inner sleeve, will no longer discard the entire container with outer sleeve and inner sleeve as a whole. In order to reduce the amount of waste, it is advantageous if the inner sleeve has a thin wall. For this purpose it is proposed that the inner sleeve have a wall thickness of 0.1 to 1 mm, especially 0.3 to 0.8 mm. The reduced thickness of the wall of the inner sleeve has the additional advantage that the useful space that remains inside the inner sleeve, intended to be recharged with the extensible mass, is especially large. The fixed connection against releasable rotation of the inner sleeve with the outer sleeve can be made in a different manner. In an advantageous embodiment of the invention, the connection part located in the inner sleeve projects from the inner sleeve and has a variable cross-sectional area in the longitudinal direction of the inner sleeve. A configuration of this type is found in the second embodiment of the invention described below with the aid of FIGS. 3 to 5. In another preferred embodiment of the invention, the fixing means are configured as at least one elastically flexible lip. , directed out of the open side. The lip placed on the inner sleeve, which can be designated as a flange, serves for the fixed connection against releasably turning the inner sleeve with the outer casing. An embodiment of this type is described in detail later in the example according to FIGS. 10 and 11. When several such lips projecting from the bushing are provided, these lips can serve as fixed legs for the inner bushing. , so that the filling of the inner sleeve with the mass extendable by the manufacturer is facilitated. In another preferred embodiment of the invention, the piston has an inner part with the internal thread for the threaded spindle and an outer part movable relative to it on the longitudinal axis of the inner sleeve, arranged in a ring around the part inside. In addition, means are provided for limiting the longitudinal movement of the outer part on the outer wall of the outer part and on the inner wall of the inner sleeve in the region of its open end. When almost all the extensible mass is consumed, the piston collides with its outer part in the limiting means in the inner wall of the inner sleeve. In the case of additional rotation of the threaded spindle, the inner part of the piston is pressed beyond the edge of the outer part and thus also presses the rest of the extendable mass out of the inner sleeve. A corresponding exemplary embodiment is explained in more detail below with the aid of FIGS. 7 to 9. Furthermore, it is proposed that the connecting parts of the inner sleeve and the actuating element are designed axially displaceable relative to each other., but in fixed union against each other. One of the joining parts can be, for example, a square mandrel and the other joining part can be an orifice with a corresponding square cross-section. Finally, a movable pusher is still proposed in the longitudinal direction, which acts on the inner sleeve, which is guided through the activation element towards the outside. The pusher facilitates the extraction of the spent bushing. For this purpose, the part of the pusher directed outwards is pressed, so that the inner sleeve is released from the outer sleeve and moves in the direction of the open end of the outer sleeve. A corresponding embodiment of the invention is described in detail below with the aid of FIGS. 10 to 12. Exemplary embodiments of the invention are explained in detail below with the aid of drawings. In the respective figures, the corresponding parts are provided with the same reference signs. In this case: S5I.! -_ 5 - §l-5 ----? Í2 --_ 2§ - l: * 5 --- I-; --- i * -?

Figure 7 shows a section along the line VII-VII in figure 6. Figure 8 shows a detailed view of the piston according to figure 7 when its first final position is reached. Figure 9 shows a view of the piston corresponding to figure 8 when its second final position is reached. Figures 10 and 11 show a fourth exemplary embodiment essentially in the longitudinal section before and after joint joining and Figure 12 shows a partially fragmentary perspective view in the direction of arrow XII in Figure 11. The container generally designated with l in the drawing 2 comprises an inner bushing 3 open on one side with extensible mass 4, especially adhesive mass, and an outer bushing 5, which at least partially surrounds the inner sleeve 3. The inner sleeve 3 is fixed to the outer sleeve 5 with the aid of fixing means 6 arranged therein, which cooperate in the assembled state of the container 1 with retaining means 7 of the outer sleeve 5. In the exemplary embodiment according to FIGS. 1 and 2, the fastening means 6 comprise eye-shaped recesses 9 of the lock in the lower edge of the wall of the inner sleeve 8 and the means of The retention elements 7 consist of pins 10 on the inner wall of the outer sleeve 5. The pins 10 form a releasable retaining snap connection with the recesses 9 as soon as the inner sleeve 3 has been fully inserted into the outer sleeve 5. Movable means 11 are arranged in the axial longitudinal direction for the dosable transfer of the mass 4 to the inner sleeve 3. These means 11 are configured as a piston 12 tightly fitted in the inner sleeve 3, movable sliding along the inner wall of the inner sleeve 3 in the axial longitudinal direction, which has in the center a through hole 13 with a screw thread. The inner sleeve 3 provided as a rechargeable container also has an actuating means 14 connected to the means 11, which is embodied as a threaded spindle 15 in the examples shown, which is mounted rotatably on the bottom 16 of the inner sleeve 3 around the its longitudinal axis. The actuating means 14 or the threaded spindle 15 has a connecting part 17 projecting from the bottom 16 and which is accessible from the outer side of the inner sleeve 3. The connecting part 17 has its periphery parallel to the longitudinal axis of the threaded spindle 15 at least one angular edge. In the example according to FIGS. 1 and 2, the connecting part 17 is configured as a square in the form of a bar. The outer sleeve 5 consists of a housing 18, which surrounds the inner sleeve 3. On the bottom 19 of the outer sleeve 5, in an orifice configured coaxially with the threaded spindle 15, an activation means 21 is cooperatively mounted which cooperates with the part connection 17 of the inner sleeve 3 or of the threaded spindle 15. The actuation means 21 is configured as knurled nut 20 operable by hand. The wall thickness of the housing 18 is chosen in such a way that it has a rigidity significantly greater than the wall 8 of the inner sleeve 3 provided as a rechargeable container. Therefore, the housing 18 can assume the activating forces exerted on the container 1. The knurled nut 20 operable by hand presents in the center of its side facing the outer sleeve 5 and the inner sleeve 3 a part Enhanced connection, coaxial to the threaded spindle 15, which is provided with a recess 22, which is complementary to the connection part 17 of the inner sleeve 3 or of the threaded spindle 15. The connection part of the knurled nut 20 is guided through the hole in the bottom 19 of the outer sleeve 5 and engages behind the bottom 19 on the inner side of the sleeve, so that the knurled nut 20 operable by hand is fixed rotatably in the bottom 19. When the inner sleeve 3 is inserted in the sleeve 5, the connecting part 17 of the threaded spindle then engages in the recess 22 or in the hole of the connecting part of the knurled nut 20, so that in this way the threaded spindle 15 is engaged or can be engaged in the nut knurled 20. By means of corresponding geometric configurations of the recess 22 and of the connection piece 17, which prevent a slippage of the connecting piece 17 in the recess 22 with the rotation of the knurled nut 20 ensures that in the rotary activation the knurled nut 20 rotates the threaded spindle 15 and in this way the piston 12 moves towards the open side 2 of the inner sleeve 3. The inner sleeve 3 is fixed with the fixing means 6 and 7 help in the outer sleeve, so that they do not perform relative movements with each other in the case of activation of the knurled nut 20. Only the piston 12 moves with respect to the bushings 3 and 5 According to the direction of rotation of the knurled nut 20, the piston moves up and down in the inner sleeve. The extensible mass 4 is moved with the piston and dispensed from the container 1 in the case of the corresponding activation of the knurled nut 20. For the protection of the extensible mass so that it does not dry, a cover can be placed on the outer sleeve 5. 6. The closure cap 23 has fastening means 24 configured on the inside of the wall of the closure cap (see FIGS. 7 and 11), which provide a retaining connection when the closure cap is engaged. on the outer sleeve 5 with fastening means 25 of the outer sleeve 5 configured correspondingly complementary. The use of the first exemplary embodiment of the container according to the invention is described below. The container 5 delivered to a user normally has an inner sleeve 3 filled with the extendable mass 4. After removing the closing lid 23, the extendable mass 4 can be removed, the user turning the knurled nut 20 with respect to the container 1, whereby the piston 12 presses the expandable mass outwards from the container 1, so that the extensible mass 4, for example adhesive mass, lip cream or the like, can be spread on a surface to be treated. When the extensible mass 4 has been consumed, that is to say, when the inner sleeve 3 is empty, the inner sleeve 3 can easily be removed from the container 1 or from the outer sleeve 5, by extracting it. The retaining connection between the pins 10 and the keyhole eye cutouts 9 is adjusted so that the inner sleeve 3 can be easily removed outside the outer sleeve 5. The part to be replaced consists of the inner sleeve 3, the piston 12, the threaded spindle 15 and the connecting part 17. After removing the inner sleeve 3 with the adjacent parts, a rechargeable container can be inserted in the container 1 or in the outer sleeve 5 as a new inner sleeve 3, retain and in this way reuse the container 1. The relatively simple replacement of the inner sleeve 3, which requires only a short time, facilitates the use of the container 1 with the inner caps 3 as a rechargeable container. The repeated use of the container 1 consisting of the outer sleeve 5 and the knurled nut 20 operable by hand reduces the consumption of raw material and the amount of waste resulting therefrom. For additional reduction of the material of the substitution part, the inner sleeve 3 provided as a rechargeable container is made of very thin wall. It has wall thicknesses of 0.1 to 1 mm, preferably 0.3 to 0.8 mm. Also the threaded spindle 15 can be made relatively thin, so that the amount of material used in the rechargeable container 3 is relatively small. In this case, the reduced dimensions of the wall
8 of the inner sleeve 3 and the threaded spindle 15 have the additional advantage that the useful space that remains inside the inner sleeve 3 or the outer sleeve 5, provided for filling with the extendable mass 4, is especially large. Since the user, due to the simpler recharge than in the rechargeable system described in the introduction of the description, is more inclined to use the container 1 several times, the consumption of material in general is reduced compared to the rechargeable system known, although in the rechargeable system according to the invention the threaded spindle is also replaced. In the second embodiment of the container
1 according to FIGS. 3 to 5, the fixing means 6 and the connecting part 17 of the sleeve 3 are configured as a unit, that is to say grouped in one element. The connecting part 17 has a non-constant cross-sectional shape in the direction of the longitudinal axis of the threaded spindle 15 with a narrowed part 26 and a handle 27 which is connected to it. The recess 22 has a configuration complementary to this shape of the connection part 17. The recess 22 is provided in the vicinity of the hole 28 with a recess-shaped narrowing, which engages in the area 26 of the connection part 17. This narrowing is formed in the connection part configured in the knurled nut 20 of elastically movable lips 30, directed towards each other. The inner sleeve 3 is fixed in this embodiment in the inner sleeve 5, by inserting the inner sleeve 3 into the housing 18 of the outer sleeve 5 until the connection part 17 elastically snaps into the recess 22 of the piece connection of the knurled nut 20. Therefore, the inner sleeve 3 is fixed on the outer sleeve 5, the lips 30 movably locking elastically behind the handle 27 of the connecting piece 17. To secure the inner sleeve 3 against rotation in the outer sleeve 5, the inner sleeve 3 is equipped with a number of longitudinal ribs 29, which cooperate with cams or strips disposed on the inner side of the outer sleeve 5 (not shown here). These elements shown in FIG. 4 are also present in the embodiment according to FIGS. 1 and 2.
In addition, in Figure 4, the bushing 3 is provided with a closure cap 23a. A unit of this type made up of the inner sleeve 3 and the closing cap 23a can be operated without problems as a rechargeable unit separately from the container constituted by the outer sleeve 5 with knurled nut 20. Furthermore, from FIG. 4 it is also deduced that the wall 8 of the inner container 3 extends beyond the connection part 17 projecting from the bottom 16, so that the sleeve 3 can be adjusted vertically in a very stable position. In this way the filling of the inner sleeve 3 with the extensible mass 4 during manufacture is considerably facilitated. In figures 6 to 9 a third embodiment of the container is shown, in which the outer sleeve 5 has a partially fragmented wall 18. Through the holes 31 formed in this way, the filling level of the inner sleeve 3 can be seen when the inner sleeve 3 is made of transparent plastic. The outer sleeve 5 differs in addition to the previous embodiments because it is open on two sides. The dimensions of the outlet orifice 32 are, in fact, smaller than the diameter of the inner container 3, so that for the introduction of the inner sleeve 3 into the outer sleeve 5 an intake hole 33 is provided, which is on the opposite side to the outlet orifice 32. Therefore, the actuating means 21 or the knurled nut are arranged in this exemplary embodiment detachably in the outer sleeve 5. The fixing means 6 and the retaining means 7 of the inner sleeve 3 and the outer sleeve 5 are designed as a bead and groove or as ribs that mesh with each other. The inner sleeve 3 is inserted downwards into the outer sleeve 5 until the fixing means 6 and the retaining means 7 establish a snap connection. Then, the knurled nut 20 or the activation means 21 is coupled., which has the recess 22 cooperating with the connection piece 17, on the connection piece 17, so that the container 1 is ready to operate. For removal of the inner sleeve 3 from the outer sleeve 5, the knurled nut 20 is withdrawn from the connection piece 17 and the retaining connection of the fixing means 6 and the retaining means 7 is loosened by lightly compressing the wall 18 of the outer sleeve 5 in a direction parallel to the fixing means, so that the inner sleeve 3 can be extracted outside the outer sleeve 5. In the example shown in FIGS. 6 to 9, the piston 12 is formed from two parts 34. and 35 arranged concentrically to each other, releasable from each other.
The inner part 34 has the hole 13 with the inner screw thread and is firmly fixed in its starting position behind an edge 36 of the outer part 35 projecting inwards. In this relative position of the two parts 34 and 35 relative to one another, the piston 12 moves to the final position shown in FIG. 8. The inner sleeve 3 has in the vicinity of its open end 2 means 37 for limiting the displacement of the piston 12 beyond the position shown in figure 8. The means 37 are configured in the form of a surrounding cord disposed on the inner side at the upper outer edge of the inner sleeve 3. When the extendable mass 4 is consumed except the rest that it is deduced from FIG. 8, the piston 12 pushes with the outer part 35 with its edge 38 into the limiting means 37 of the inner sleeve 3. If the knurled nut 20 is now activated further and, therefore, the threaded spindle 15 , then the inner part 34 of the piston 12 is pushed beyond the edge 36 of the outer part 35, so that also the last rest of the extendable mass 4 is pushed out of the piston 12. The ex Terior 35 is equipped on its upper side with means 39 for limiting the movement of the inner part 34 in the form of a cord projecting inwardly. The inner part 34 is provided with a recess 40 or with a notch surrounding it on the edge side, which cooperates with this edge. When the final position shown in Fig. 9 of the inner part 34 is reached, the inner part 34 and the outer part 35 of the piston 12 form a flat upper surface, so that the piston 12 is emptied without debris outside the extendable mass.
4. The means shown 37 for limiting the movement of the piston 12 can obviously also be provided in the first and second embodiments of the object of the invention. In this case, the additional activation of the threaded spindle 15 - as soon as the piston has reached the final position shown in figure 9 - leads to the inner sleeve 3 being pressed out of the outer sleeve 5 under the release of the retaining connection with the outer sleeve 5 and the knurled nut 20. A similar action also has the limiting means 39 of the piston 12 composed of the parts 34 and 35, when these are present in a container according to the first or second embodiments. In the examples shown hitherto, a connecting part 17 is shown in projection of the drive means 14 and a recess 22 for receiving the actuating means 20. Obviously, also the connecting part 17 of the actuating means 14 can be equipped with a recess, therefore it can serve as a housing part, while in the upper part of the actuating means 21 or of the knurled nut 20 a correspondingly shaped connecting part is formed, which positively engages in the connecting part 17 of the inner sleeve 3. An embodiment of this type is represented as a fourth exemplary embodiment of the invention in FIGS. 10 to 12. There, the connecting part 41 in projection of the knurled nut 20 engages in connection positive in the connection part 17 of the threaded spindle 15. In the embodiment according to FIGS. 10 to 12, the connection piece 41 in FIG. The knurled nut 20 has a cross-section in the form of a star with a plurality of ribs 56, while the connection piece 17 has a star-shaped recess. In this fourth embodiment, some flexible lips 42 arranged in the lower part of the inner sleeve 3 are provided as fixing means 6. The lips 42 are evenly distributed over the periphery of the lower edge of the inner sleeve 3, on which they are projected to an insignificant extent. In this way it is possible that the inner sleeve 3 can be during the filling with extendable mass 4 aligned vertically on the lips 42. The lips 42 are provided with a shoulder 45 whichwhen the inner bushing 3 is inserted in the outer bushing 5 it grips frictionally in a surrounding strip formed in the lower area on the inner side on the inner wall of the outer bushing 5 under the formation of a retaining connection. The outer sleeve 5 connected to the knurled nut 20 by means of a connecting piece 41 through a hole in its bottom 19 further has a guided ejection element 43 movable in the longitudinal direction in a hole 50 of the knurled nut 20. The ejection element 43 comprises a push button 46, a plurality of elastic arms 47 arranged in a circumferential direction in the push button 46, and a pushing member 49. The push button 46 and the arms 47 are displaceable in the longitudinal direction axially in an inner space 57 of the knurled nut 20. The pushing member 49 extends through the hole 50 of the knurled nut 20 and through the connecting piece 41 in projection. The threaded spindle 15 has at its lower end, following the space of the connecting means 17 receiving the connection piece 41, a space 51 that receives the pushing element 49. This receiving space 51 is provided on the end side with an abutment shoulder 53 circumscribing in the form of a ring, against which it abuts - as can be seen from FIGS. 10 and 11 - the end surface 52 of the thrust element 49. In the insertion of the inner bushing 3 in the outer bushing 5 , the stop shoulder 53 abuts the end surface 52 of the thrust element, so that after the complete insertion of the inner bushing 3 in its final position inside the outer bushing 5, the pressing element 43 is brought into position starting point shown in figure 11. Shortly before the lips 42 of the inner sleeve 3 engage behind the strip 44 of the outer sleeve 5, the arms 47 of the ejection element 43 collide on the strip 48 The inner sleeve of the inner space 57 of the knurled nut 20. The inner sleeve 3 moves inside the outer sleeve 5 until the flange 42 engages with its respective shoulder 45 behind the lath or cord 44, thereby the arms 47 of the ejection element 43 resting on the slat 48 are slightly bent, so that a pressing force on the stop shoulder 53 of the threaded spindle 15 is exerted on the stop surface 52 of the pushing element 49. The inner bushing 3 is thus fixed under pretension in the outer bushing 5, so as not to provide possible relative movements of the inner bushing 3 and the outer bushing 5 which are possibly produced by virtue of manufacturing inaccuracies in the case of movements of vibration of the container 1. To ensure in the conditions of this pre-tension a perfect rotary movement of the knurled nut 20 can be activated by hand with respect to the or to the housing 18 or to the outer sleeve 5, a support ring or sliding ring is provided between the knurled nut 20 and the bottom 19 of the outer sleeve 5. This ring 54 is fixed in the radial direction by means of a cord 55 in the form of ring projecting from the bottom 19 of the casing 18. After consumption of the extendable mass 4 which is in the inner sleeve 3, the piston 12 is located on the upper edge of the inner sleeve 3 on the open side 2. If a pressing force is exerted on the push button 46 in this position, the threaded spindle 15 mounted on the bottom 16 of the inner sleeve 3 is pressed in this way in the direction of the open side 2, the lips 42 being released outside their joint and the inner sleeve 3 projecting slightly out of the outer sleeve 5. This can now be easily grasped and can be removed outside the outer sleeve 5. Then the outer sleeve 5 It can be recharged again by introducing a new 3 inner bushing. In all the embodiments shown, the inner sleeve 3 has a wall 8, which extends over the entire axial longitudinal extension of extensible mass 4. But it is also possible that the inner sleeve 3 has only a bottom 16 and walls extending thereon over a length or height short, where the height or depth of an inner bushing 3 of this type need not be greater than the piston 12 received therein, whereby it is offered to the molded body of extendable mass, which extends over the length of the outer bushing 5, sufficient anchoring and support when moving up and down inside the container 1.

NOVELTY OF THE INVENTION
Having described the foregoing invention, it is considered as novelty, and therefore, the content of the following is claimed as property:
