Definitions

  • the present invention relates to a spring-loaded pusher made of plastic, which is longitudinally displaceable against the spring force and is automatically returned to its initial position thanks to the spring system forming an integral part of the pusher, and to the use of the pusher in a tablet dispenser device.
  • Dispenser devices for the individual dosing of tablets are known and are used in particular for sweetener tablets. These dispenser devices are usually made of plastic.
  • the single dispensing of a tablet is triggered in a known manner by operating a pusher.
  • An elastic spring forming an integral part of the handle ensures that the handle is returned to the starting position.
  • this handle is therefore manufactured with a spring system in the form of a simple leaf spring made of a plastic with known good permanent elastic properties, e.g. Polyacetal (polyoxymethylene, POM).
  • the packing body i.e. the container itself, however, is usually made of much cheaper and more environmentally friendly plastics, such as polystyrene (PS), polyethylene (PE) or polypropylene (PP).
  • PS polystyrene
  • PE polyethylene
  • PP polypropylene
  • EP-A-100275 (priority CH 2300/98) describes a pusher with a spring system designed in this way, which, in addition to the usual materials, can alternatively also be produced using the less expensive and more environmentally friendly plastics which are used to produce the package body without the desired permanent elasticity of the spring system is questioned.
  • Such a pusher according to the preamble of claim 1 is particularly suitable for known dispenser devices for single tablets.
  • the spring system used consists of two intersecting spring arms which slide against one another at the crossing point and which, as integrating parts of the lever, essentially extend freely in the direction of the longitudinal axis of the lever, the free ends of which are intended to slide against a fixed stop , such that when the handle is actuated, the arm sections between the free arm ends and the crossing point and the arm sections between the crossing point and their attachment point on the handle each bend under load as separate spring systems.
  • This now known spring system made of plastic preferably made of PP, PS or PE, is optimized in its shape in such a way that under the required operating conditions the material-specific limit values of the elastic load capacity are not exceeded, with a similar elastic behavior (pressure build-up and restoring force, functional reliability) as with a Spring system made of common materials (e.g. POM).
  • the object of the present invention was to provide a pusher with a novel spring system, which also consists of inexpensive and environmentally friendly plastic that can be disposed of, but is designed in such a way that it is also suitable for shorter spring travel, such as with smaller tablet dispensers, without the to lose or deteriorate functional properties.
  • Figure 1 of the drawing shows purely schematically a tablet dispenser 1 in four different positions of the spring-loaded pusher 2.
  • the function and structure of such tablet dispensers are known and are not described in more detail here.
  • the pusher 2 of sole interest here consists of a pusher body 3 (pusher head) with two leaf spring units 4, 5 integrated, ie molded on, and is made of plastic, preferably on polystyrene (PS), polyethylene (PE). or polypropylene (PP).
  • PS polystyrene
  • PE polyethylene
  • PP polypropylene
  • this material is much cheaper and is more environmentally friendly to dispose of, but has poorer permanent elastic properties.
  • the spring system was designed in accordance with the invention.
  • the pusher construction according to the invention with the two integrated leaf spring units 4, 5, each of which consists of two leaf springs 4 ', 4 "or 5', 5" lying at a short distance above one another (see in particular FIGS. 2-4), the front sections of which are located in Cross operation freely (see Figures 1, 3 and 4) is optimized in such a way that the material-specific limit values of the elastic load capacity are not exceeded under the required operating conditions.
  • the handle is made of the preferred materials (PS, PP, PE)
  • its spring system has a similar elastic behavior (pressure build-up and restoring force) as a spring system made of common materials (e.g. POM). The problem of spring fatigue or spring breaks does not arise.
  • the design of the handle or its spring system according to the invention is particularly suitable where only short spring travel is available, such as for smaller tablet dispensers.
  • Figure 1 illustrates various positions of the pusher 2 and its spring system 4, 5 in the example use in a sweetener tablet dispenser with only a small spring travel.

Claims (6)

  1. Bouton pressoir (2) sous l'action d'un ressort, en matière plastique, qui peut être déplacé contre la force du ressort dans une direction longitudinale et qui est automatiquement ramené dans sa position initiale grâce au système ressort formant partie intégrante du bouton pressoir, ledit système ressort comprenant deux unités séparées de ressorts à lames (4,5) formant parties intégrantes du bouton pressoir et s'étendant librement à partir du corps (3) du bouton pressoir essentiellement en direction de l'axe longitudinale du bouton pressoir, les extrémités libres desdites unités de ressorts à lames étant prévues pour s'appuyer essentiellement simultanément et de manière à pouvoir glisser contre une butée stationnaire et de manière à pouvoir se croiser dans la zone terminale suite à leur actionnement et déformation élastique, caractérisé en ce que chacune des deux unités de ressorts à lames (4,5) comprend deux lames de ressort séparées (4',4'';5',5'') ayant essentiellement même longueur et se superposant à faible distance, lesdites lames de ressort individuelles étant façonnées de telle manière respectivement connectées au corps (3) du bouton pressoir de telle manière qu'en opération les deux unités de ressorts à lames (4,5) puissent se croiser librement.
  2. Bouton pressoir (2) selon la revendication 1, caractérisé en ce que les deux lames de ressort (4',4'',5',5'') de chaque unité de ressorts à lames s'étendent vers l'avant à partir de zones marginales opposées de la face frontale du corps (3) du bouton pressoir.
  3. Bouton pressoir (2) selon les revendications 1 et 2, caractérisé en ce que les deux unités de ressorts à lames (4,5) opposées sont décalées l'une par rapport à l'autre de telle manière qu'en opération elles puissent se croiser librement.
  4. Bouton pressoir (2) selon les revendications 1 et 2, caractérisé en ce que les lames de ressort (4',4'';5',5'') des deux unités de ressorts à lames opposées (4,5) sont encochées au moins dans leur partie frontale, réduisant ainsi leur largeur de telle manière qu'en opération les deux unités de ressorts à lames puissent se croiser librement.
  5. Bouton pressoir (2) selon l'une des revendications 1 à 4, caractérisé en ce que le bouton pressoir (2) et par conséquent le système ressort est en polystyrène, polypropylène ou polyéthylène.
  6. Utilisation du bouton pressoir (2) selon l'une des revendications 1 à 5 dans un dispositif de distribution pour le dosage individuel de tablettes, notamment de tablettes sucrantes.
