Definitions

  • the invention relates to a dispenser according to the preamble of claim 1.
  • dispensers are used in particular for pasty media, such as toothpaste, personal care products, and also for foods, such as mayonnaise, mustard, etc.
  • Dispensers are known in which the piston moves upward into the container by a kind of pumping movement on an externally accessible pressure piece due to overpressure or underpressure and pushes the filling material in front of it.
  • the contents are 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 the overall result is a complex and functionally sensitive construction. (e.g. DE-OS'en 2901717,3105859).
  • dispensers are known (DE-OS'en 2 941 416, 3 007 480), 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 on 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-1 607 905, EP-OS-0 053 329) in which the piston is secured against falling with spring support.
  • dispensers are known according to the preamble of claim 1, in which the piston is moved mechanically by means of an external actuation, the stroke movement being generated directly by hand (DE-GM-7 908 402, 8 229 055) or via mechanical transmission means.
  • the first-mentioned embodiment has the disadvantage that the container is increasingly shortened when emptied.
  • a rack is connected to the underside of the piston. This sits in a guide part adjoining the container.
  • a gearwheel cooperates with the toothed 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.
  • operation is practically only possible with two hands, so that the dispenser for many applications, such as toothpaste, not at all and for many other applications, e.g. B. personal care products, 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 allows both a portioned and a continuous dispensing of the filling material.
  • the dispenser according to the invention consists of only two components, namely the container on the one hand and the piston with the double-walled slide connected to it, the piston and slide being guided on the container wall, a preferred type of guidance having the features of claim 2 .
  • the assembly of the two parts is very simple, after filling the container in a conventional manner, i. H. the piston is inserted from the open bottom, the double-walled slide being pushed onto the edges of the container wall which delimit the slot. By pushing the outside handle, the piston is moved in the direction of the dispensing opening, pushing the filling material in front of it and allowing it to exit through the dispensing opening.
  • the quantity of the filling material escaping is determined exclusively by the pushing movement with the hand or the finger, so that individual portioning is possible. Since there are no built-in components in the area of the dispensing opening, the piston can be moved to the dispensing opening and the container can be completely emptied.
  • the dispenser can also be operated without difficulty with one hand, by gripping it in the area of its lower guide part and pushing the slider 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. This is because 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. be arranged 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 each other only in the area of the lower end, is given an absolutely stable position in any position by the additional guide that extends over the outer wall. In particular, this will spread the outer wall of the slide avoided.
  • 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 is guided on the outside over its entire length and over the entire stroke.
  • 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, rest over a larger area of the container wall.
  • 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, with corresponding guides only having to be provided in the jacket of both container walls.
  • the discharge 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.
  • the dispenser shown in the drawing consists essentially of a container 1, of z. B. cylindrical shape, a piston 2 slidably guided therein and a slider 3 connected to it with a handle 4 in the form of a push button.
  • the piston 2 which is optionally additionally provided with sealing lips 5, is located in its starting position approximately in the central region of the container 1.
  • the upper region between the piston 5 and the discharge opening 6 is filled with a pasty or liquid medium, while the container 1 beyond the piston 2 forms a guide member 7 of substantially hollow cylindrical shape.
  • the guide part 7 can be provided with an edge reinforcement 8 at 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 engages over 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 extend to the upper end of the slide 3, so that it is already 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.
  • At the bottom of the piston 2 there are additional ribs 16 molded onto the inside of the wall of the container 1. They give the piston 2 an additional guide and the container a stiffener.
  • the discharge 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 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 provided on the outside with a circumferential corrugation 21 which favors the operation.
  • the push button 4 can have a corrugation 22 on its underside.
