Definitions
- Dispenser for pasty or flowable media
- the invention relates to a dispenser according to the preamble of claim 1.
- dispensers are used in particular for pasty media, such as toothpaste, body care products and also for foods, such as mayonnaise, mustard, etc.
- Dispensers are known in which the piston moves upwards into the container due to overpressure or underpressure by means of a kind of pumping movement on an externally accessible pressure piece and pushes the filling material in front of it.
- the filling material is always dispensed in portions.
- these dispensers require valves at the discharge opening in order to be able to generate a negative pressure or to maintain an excess pressure.
- These dispensers therefore consist of a large number of components which must be closely tolerated, so that overall there is a complex and functionally sensitive construction. (e.g. DE-OS'en 29 01 717, 31 05 859).
- dispensers are known (DE-OS'en 29 41 416, 30 07 480), in which the piston is additionally secured against slipping back after the lifting movement, for example by being designed as a type of climbing piston, which is either attached to a guide rod and / or is blocked on the inner wall of the container by expansion parts, catches or the like.
- These constructions are also complex and cause problems with the sealing.
- constructions are known (DE-AS 16 07 905, EP-OS 0 053 329) in which the piston is secured against falling with spring support.
- dispensers according to the preamble of claim 1 are known, in which the piston is moved mechanically by means of an external actuation, the lifting movement being generated directly by hand (DE-GM 79 08 402, 82 29 055) or via mechanical transmission means.
- the first embodiment mentioned has the disadvantage that the container is increasingly shortened when emptied.
- a toothed rack is connected to the underside of the piston. This sits in a guide part adjoining the container.
- a gearwheel cooperates with the rack, which is mounted in the guide part and can be rotated from the outside.
- the problem here is the guidance of the rack and the bearing of the handwheel. It is always an advantage that the contents can be dispensed in any portion.
- operation is practically only possible with two hands, so that the dispenser for many applications, for example toothpaste, not at all and for many other applications, e.g. B. body care tel etc., is at best conditionally suitable.
- the object of the invention is to provide a simple and functionally reliable dispenser from a minimum of components, which enables both a portioned and a continuous dispensing of the filling material.
- the fiction, contemporary dispenser consists of only two components, namely the container on the one hand and the piston with the attached double andi gene slide, on the other hand, the piston and slide on the Container wall are guided » where there is a preferred type of guidance with the features of claim 2.
- the assembly of the two parts is very easy by, that is, the plunger is inserted after filling of the container in herkömm ⁇ Licher manner from the open bottom thereof, wherein the double-walled slider is slid onto the bounding the slit edges of the container wall.
- the piston By pushing the outer handle, the piston is moved in the direction of the discharge opening, pushes the filling material in front of it and allows it to exit through the discharge opening.
- the amount of the emerging filling material is determined exclusively by the pushing movement with the hand or the finger, so that an individual por ionization is possible. Since there is no need for any internals in the area of the discharge opening, the piston can be moved to the discharge opening and the container can thus be completely emptied.
- the dispenser can also be operated with one hand without difficulty by reaching around in the area of its lower guide part and pushing the slide forward, for example with the thumb. The position of the slide gives a direct indication of the level in the container. A separate securing of the piston against slipping back is not necessary, even if this will not usually happen. Namely, it can easily be pushed back towards the filling material or moved to compress the filling material.
- the discharge opening can be in the axis of the container or laterally, for. B. in the manner of a spout.
- a preferred embodiment is characterized in claim 3. It ensures that the double-walled slide, the two walls of which are connected to one another only in the area of the lower end, is given an absolutely stable position in any position by the additional guide which extends over the outer wall. In particular, this prevents spreading of the outer wall of the slide.
- the guide can also deviate from the features of claim 3 to the lower end of the guide part of the container, so that the outer wall of the slide over its entire length and is also ' guided on the entire path.
- this additional guide helps to stabilize the container wall and thus also to the proper guidance of the piston in the container.
- the overall guidance can be favored in that the inner and outer wall of the slide, which are designed according to the cross-sectional shape of the container, for example partially cylindrical, fit over a larger area of the container wall.
- the feature of claim 4 results in a configuration which is favorable for handling, in that the entire container can be encompassed in the region of the guide part and at the same time there is sufficient scope for pressing the slide.
- additional stiffening of the container and improved guidance of the piston is achieved, as is also possible with the embodiment of claim 6.
- the additional bottom connected to the screen also forms the lower end of the guide part of the container, so that a particularly satisfactory design is provided.
- defined portions of certain face or volume can be delivered.
- the design according to the invention can be used in containers with a circular, oval, rectangular cross section with rounded corners or the like in an equally advantageous manner. Double-walled containers are also possible, corresponding guides only have to be provided in the jacket of both container walls.
- the dispensing opening can also be designed in the form of a nozzle for squeezing the emerging filling material. Furthermore, it can have inserts or cross sections that form the emerging strand.
- a plurality of channels can also be provided in the area of the discharge openings in order to dispense different or differently colored filling goods side by side in one strand.
- FIG. 2 shows a section II-II according to FIG. 1;
- FIG. 3 shows a section III-III according to FIG. 1;
- Fig. 4 shows a longitudinal section through another
- FIG. 5 shows a view of the dispenser according to FIG. 6 shows a section VI-VI according to FIG. 4.
- the dispenser shown in the drawing consists essentially of a container 1, of z. B. cylindrical shape, a displaceably guided piston 2 and a connected to this Sch eber 3 with a handle 4 in the form of a push button.
- the piston 2, which is optionally also provided with sealing lips 5, is in its initial position e wa in the central region of the container 1.
- the upper region between the piston 5 and the discharge opening 6 is in the form of a paste-like or liquid medium filled, while the container 1 beyond the piston 2 forms a guide member 7 of substantially hollow cylindrical shape.
- the guide point 7 can be provided with an edge reinforcement 8 on its lower edge.
- the container 1 has in its lower guide part 7 an axially parallel longitudinal section 9 which extends to the lower end and is open there. The length of the slot 9 corresponds to the total stroke of the piston 2 between the position shown in FIG. 1 and a position in the region of the neck 10 of the container 1.
- the slide 3 is double-walled and has an outer wall 11 and an inner wall 12, which are connected to one another at their lower end via a web 13 and in this way form a type of slim "U".
- the inner wall 12 is connected to the piston 2 at its upper end.
- Both walls 11, 12 of the slide 3 lie, as shown in particular in FIG. 3, on the wall of the container 1 on both sides of the longitudinal slot 9. The slide 3 is thus guided on both sides of the container wall.
- a further guide 14 is also provided on the outer wall of the container 1, which overlaps the outer wall 11 of the slide 3 on the outside in the manner of a tongue and groove guide.
- This guide 14 should be present at least in the upper region of the container 1 and should extend to the upper end of the slide 3, so that it is also guided on the outside in the initial position of the piston 2. It can of course also be extended to the lower edge 8 of the container 1.
- the piston 2 is arched upwards to a vertex 15, the contour of the top of the piston corresponding to the contour on the inside of the container 1 in the region of its neck 10 in order to enable the container to be completely emptied. Additional ribs 16 are formed on the underside of the piston 2, which abut the inside of the wall of the container 1. They give the piston 2 an additional guide and the container a stiffener.
- the dispensing opening 6 is narrowed like a nozzle and closed by a guarantee closure 17, after the separation of which the dispenser is functional.
- the embodiment according to FIGS. 4 to 6 for example in the form of a paste tube, has a bottom part 19 which closes off the container at the bottom and which is formed on the slide 3 and guided inside the container 1. ' This bottom part 19 is connected to the piston 2 by means of ribs 18, which in turn results in better guidance and stabilization and, above all, prevents the piston from tilting, similar to the way in which the guide ribs 16 according to FIGS. 1 and 3 are used.
- a scale 20 is arranged in the area of the guide 14, which overlaps the slide 3 on the outside, and the push button 4 is used to read it directly.
- the container 1 can be seen on the outside with a circumferential corrugation 21 which favors the operation.
- the push button 4 can also have a corrugation 22 on its underside.
