Definitions
- Dispenser for pasty substances in particular
- the invention relates to a dispenser for in particular pasty substances with an exchangeable storage container, the storage container preferably being designed as a storage bag with a thin, foldable wall, furthermore having an opening end and a bottom end, the bottom end being reinforced.
- a donor is known, for example, from EP-A2 219 750.
- a storage bag is emptied in the dispenser by an axial pressure actuation.
- Such a dispenser is still perceived as relatively complex in terms of its emptying mechanism.
- the invention is based on the object of specifying a dispenser for pasty substances in particular which, with a simply constructed storage bag, enables the storage bag to be emptied with little construction. A very extensive emptying of the storage bag should also be possible as far as possible.
- a holding part is formed in the dispenser, which can be rotated about a longitudinal axis of the storage container or storage bag passing through the mouth end and the bottom end, and that the holding part with the reinforcement of the bottom end of the storage bag for twisting the Storage bag cooperates, the storage bag in the area of the mouth end is rotatably held in the dispenser.
- a dispenser is specified with a storage bag which, by twisting from bottom to top, expels the contents, in particular a pasty substance such as toothpaste, mayonnaise, ketchup or the like, but also solid substances such as a deodorant stick from the mouth end of the storage bag
- the bottom end of the storage bag is positively received in the holding part.
- the simple positive connection which for example allows insertion from above, is only necessary with regard to a twisting of the bottom end relative to the mouth end of the storage bag.
- the form fit can be designed as desired.
- the bottom end of the storage bag is axially movable in the holding part of the dispenser housing. With increasing twisting, the length of the storage bag generally shortens depending on the material. Due to the fact that the bottom end can be moved axially in the holding part, the positive connection with the holding part is not lost, but the storage bag is made possible to shorten axially.
- a suitable configuration of the bottom end of the storage bag is seen, for example, in that the bottom end is designed in the form of a polygonal rod.
- the rod can be solid or - preferably - hollow in terms of weight reduction and material savings.
- the holder part of the dispenser is designed to match the bottom end of the storage bag with an internal polygon, for example in a configuration as is known from polygonal wrenches.
- the mouth end of the storage bag is further preferably provided with a mouth cap which is formed with - outer - form-locking means, which form-locking means enable a non-rotatable mounting in the dispenser housing. Alternatively or additionally, there can be a non-positive connection.
- the bottom end can be twisted relative to the mouth end of the storage bag without turning the muzzle end.
- the storage container essentially consists of an extruded plastic film, for example a cylinder-shaped one. Very thin plastic films are preferred here. However, it is also possible to use multilayer plastic films. Alternatively, the storage container can consist of several plastic film parts, which are preferably welded together. It is further preferred that the bottom end of the storage container is molded onto the plastic film. In particular, reference is made to the German patent application P 43 21 275.1, the disclosure content of which is hereby incorporated in full in the present application. It is furthermore also possible to connect the mouth cap to the extruded plastic film by injection molding, for example in the form of a hinged closure. In particular, reference is also made to the aforementioned patent application.
- the storage container has a taper in the region of the bottom end, for fixing an initial cross section when twisting.
- FIG. 1 is a side view of the dispenser;
- FIG. 2 shows a top view of the dispenser according to FIG. 1;
- FIG. 3 shows a cross section through the dispenser according to FIG. 1, cut along the line III-III in FIG. 2;
- 4 shows a further cross section through the dispenser according to FIG. 1, cut along the line IV-IV in FIG.
- FIG. 5 shows a cross section through the dispenser according to FIG. 1, cut along the line V-v in FIG. 3;
- FIG. 6 shows a cross section through the dispenser corresponding to FIG. 3, with a partially twisted storage bag
- FIG. 7 shows a cross section through the dispenser according to FIG. 1 cut along the line VII-VII in FIG. 6;
- FIG. 8 shows an alternative embodiment of the dispenser according to FIG. 1 in a representation according to FIG. 3, with a helical spring for transmitting the torque;
- FIG. 9 shows a representation according to FIG. 8, with an extended helical spring, and a partially twisted storage bag
- FIG. 11 shows the embodiment according to the invention according to FIG. 10 without a storage bag and lid
- FIG. 12 shows the embodiment according to the invention according to FIG. 10 in the dispensing position
- FIG. 13 shows a detail of the embodiment according to the invention according to FIG. 12 immediately after returning to the idle state
- FIG. 16 shows the embodiment according to the invention according to FIG. 14 with a twisted storage bag.
- a dispenser 1 is shown and described first with reference to FIG. 1, for example for dispensing a pasty substance such as toothpaste.
- the dispenser 1 has - now with reference to FIG. 3 - a storage bag 2 which is interchangeably received in the dispenser housing 3.
- the storage bag is designed in a sack-like manner with a thin, foldable wall 2a.
- the storage bag 2 has a mouth end 4 and a bottom end 5.
- the bottom end 5 is in cross section - cf. Fig. 5 - rectangular.
- the bottom end 5 consists of a rod section 6 and a transition area 7.
- the transition area 7 represents a connection with the film wall 2a of the storage bag.
- the transition area 7 is tapered like a waist compared to a central cross section. for example in the area of line IV-IV in Fig. 3 - the storage bag.
- the rod section 6 is received in a holding part 8 of the dispenser 1.
- the holding part 8 is rotatable transversely to a longitudinal axis a of the storage bag passing through the mouth end 4 and the bottom end 5. Due to the positive reception of the rod section 6 in the holding part 8, when the holding part 8 is rotated, the storage bag is twisted, as indicated in FIG. 6.
- the mouth end 4 has outer latching cams 10 which engage in recesses 22 (cf. FIG. 4) in the dispenser wall 3, they prevent the mouth end 4 from rotating relative to the dispenser housing 3.
- the retaining part 8 of the dispenser 1 is rotated the desired twisting of the storage container is thus achieved.
- the mouth end 4 consists of a conical section 11 which is integrally connected to a cylindrical section 12 is formed.
- the cylindrical section 12 is connected to the extruded plastic film 2a.
- An outlet opening 13 adjoins the conical section 11 on the mouth side.
- the holding part 8 is connected in a rotational test (for example by gluing) to a handle 14 which is cup-shaped in cross section and which interacts with the dispenser wall 3 via a ratchet mechanism.
- the ratchet mechanism is shown in detail in FIGS. 5 and 6.
- Two spring fingers 15 are formed in the handle 14, which engage in recesses 16 oriented axially on the dispenser.
- the spring fingers 15 overlap due to a bevel 17 cams 18 (cf. rotation against the direction of the arrow). With a rotation in the direction of the arrow, a blockage occurs accordingly and the desired emptying of the storage bag 2 can be achieved.
- the handle 14 is knurled on the outside in order to enable better handling.
- the handle 14 is also axially secured in the dispenser wall 3 by means of a circumferential projection 19.
- the handle 14 simply interacts with the dispenser wall 3 via a frictional connection. If the frictional engagement is selected to be sufficiently strong, a turning back of the handle 14 is not possible due to the restoring forces of the storage container during twisting, so that this embodiment is also sufficient.
- FIGS. 8 and 9 relate to an alternative embodiment of the holding part 8.
- the holding part 8 here consists of a helical spring 20, which is still substantially perpendicular to the transmission of a torque extending transverse elements 21 are formed which are provided such that they engage in a zipper-like manner with respect to windings of the helical spring running one above the other.
- This helical spring can thus follow the bottom end axially in height with increasing twisting of the storage container without losing the ability to transmit the required torque. Accordingly, it is not necessary to design the bottom end 5 of the storage container with an adapted length (rod section 6).
- FIG. 9 shows a state in which the supply ratio already has a certain shortening. An upper end of the coil spring 20 lies in the bottom of the storage bag 2 against a rotary stop, and a lower end is firmly connected to the handle 14. This is not shown in detail.
- FIG. 10 shows a further embodiment of a dispenser according to the invention, wherein the storage bag 2 is twisted by axially pressing the housing 3 onto a base part 29 against a compression spring 30.
- a screw 32 runs into a nut 31 on the bottom 29.
- the screw 32 is fixedly connected at the point 24c to a rotating sleeve 24, in which a driver 26, which is fastened to the storage bag 2, is arranged to be axially displaceable is.
- the rotation of the screw 32 causes the storage bag 2 to be twisted via the rotation of the rotating sleeve 24 and the driver 26.
- the driver 26 is moved upward in the rotating sleeve 24.
- a cover 22 On the upper part of the storage bag 2, a flange 27 is formed with an oblique side outlet tube 13.
- the outlet pipe 13 is held in corresponding passages of the cover 22 and the dispenser housing 3 and thus prevents the bag flange 27 from rotating in the dispenser.
- the opening of the outlet pipe 13 is closed by a flap 23. sen.
- the flap 23 is articulated to a fixed ring 25 in the interior of the dispenser housing 3 and is guided through an opening 3b of the dispenser housing 3.
- FIG. 11 shows the embodiment according to the invention according to FIG. 10 without a storage bag 2 and without a lid 22.
- the ring 22 is preferably fixedly connected to the bottom 29 via 3 webs 28.
- the webs 28 are arranged at an angular distance of 120 °. They preferably have a width of 12 mm.
- Lugs 34 are formed on the webs 28, which hold the dispenser housing 3 under pressure from the spring 30 on the base 29 in the idle state.
- the rotary housing 24 is also shown. It has slots 24a into which the ends of a rod-shaped driver 26 are inserted via insertion bevels 24b.
- FIG. 12 shows the embodiment according to FIG. 10, wherein the dispenser housing 3 is pressed against the force of the spring 30 until it stops on the bottom 29.
- the screw 32 turned into the nut 31 and caused the bag 2 to twist (not shown here).
- the thread of the screw and nut has a steep pitch, preferably 100 mm height per revolution.
- the dosing quantity results from the stroke height, so that the stroke height is adapted to the substance to be dispensed.
- Pressing down the dispenser housing 3 causes a relative movement to the mounting ring 25 for the flap 23, which is fixed on the bottom 29.
- the opening 3b moves downward, the flap 23 lifts off the opening of the outlet pipe 13 and substance is released from the Storage bag 2 issued.
- FIG. 13 shows the embodiment according to FIG. 12 immediately after the spring 30 has been released.
- the nut 31 is connected to the base 29 in a form-fitting manner only in the horizontal direction. Therefore, while it was still screwed on the screw 32, it was lifted upwards by the spring 30. Due to its own weight, the nut 31 then unscrews again from the screw 32 and falls back onto the bottom 29, where it comes into positive engagement again with projections 31a in corresponding recesses 29a on the bottom.
- the rest state according to FIG. 10 is thus reached again, and the twisting can be continued by a further pressure actuation and further substance can be removed from the dispenser.
- FIGS. 14 to 16 show a further embodiment according to the invention, which is particularly suitable for a stick-shaped product of relatively firm consistency, such as a deodorant stick, glue stick or crayon.
- the storage bag 2 is connected to a rotatable handle 14 with a lid 14a via a telescopic holder 35, 36, which allows the lower end of the storage bag 2 to perform a vertical movement that occurs during the twisting.
- FIG. 14 shows the further embodiment of the dispenser 3 according to the invention in the idle state with a closure cap 39 on the dispenser housing 3 and a seal 40.
- the storage bag 2 is positively held in the dispenser by the flange 27, which preferably has an oval cross section.
- the driver 26 which is snapped into a driver sleeve 36 with hooks 26a.
- the hooks 26a protrude somewhat deeper into the carrier sleeve in order to compensate for tolerances that occur in the bag dimensions or filling.
- the driver 26 is welded to the bag 2 and projects into the storage bag 2 with a stabilizing part 26b, whereby it comes into contact with the substance 41 and thus stabilizes the position of the driver.
- the handle 14 is with a nose 14b rotatable behind a projection 3a of the dispenser housing 3 and preferably snapped into place in a slightly resilient manner. This prevents the storage bag 2 from being untwisted automatically. A certain stiffness of the handling 14 can also be achieved by slight corrugation in the transition area between the handling 14 and the dispenser housing 3.
- FIG. 15 shows the embodiment according to the invention according to FIG. 14 without a cap, the bag 2 not yet being fastened in its holder.
- the bag 2 Before insertion, the bag 2 is preferably covered with a tamper-evident device 42 (film) which is torn off when it is inserted.
- the driver 26 is inserted with the hooks 26a into a star-shaped toothing 36a in the driving sleeve 36, the hooks 26a, as already described and shown in FIG. 14, projecting beyond the toothing 36a.
- Fig. 16 shows the embodiment according to the invention according to Fig. 14 in the end position of the twisting of the bag 2, i.e. when substance 41 is almost completely dispensed.
- the driver 26 is raised and the hooks 26a engage under the star-shaped toothing 36a.
- the telescopic sleeve 35 and the driving sleeve 36 gradually slide up to the stops 38 in the grooves 37.
- FIGS. 1 to 16 have storage bags 2 with tapering on their lower part in order to determine a preferred location for the start of the twisting.
- the dispensers are essentially made of plastic.
