Definitions

• the invention is directed to a tablet dispenser for dispensing tablets individually, comprising a housing and an insertable into the housing and displaceable therein under stroke limitation inner part consisting of a tablet storage space and a tablet discharge shaft and a return spring, which is supported against the housing, for example against the bottom surface of the housing.
• a discharge opening In tablet dispensers simplest construction, the opening and closing of a discharge opening is done by a flap or a slider that are operated, for example, by hand. A separation of tablets is not provided here. Furthermore, dispensers with a arranged in the dispenser housing mechanically actuated device are known, released by the stroke-limited displacement within the dispenser housing a dispensing opening in the dispenser housing and a tablet per stroke is discharged from the dispenser housing.
• a tablet dispenser is described in which a single tablet is dispensed from a housing by pushing an actuating button, which is connected via a centrally arranged operating shaft with a slider, through a bottom-side opening.
• a tablet dispenser which consists of a prismatic housing with an open end face and a laterally offset opening in the bottom surface.
• an inner part is inserted from above, consisting of a slide and an actuating button, connected by a connecting element, which together form a structural unit in the sense of an inner housing, in the upper part of the tablet reservoir is located.
• This inner part is displaced by finger pressure on the upper part of the actuating button, the lower part being displaced by the bottom opening.
• the housing is moved and releases a tablet.
• the displacement of the inner part is stroke-limited by a web which abuts the housing bottom during the downward movement of the inner part, whereby a further downward movement is blocked.
• EP 0 831 035 B1 describes a tablet dispenser with a leaf-shaped return spring arranged on the bottom of the inner part. This return spring is at the tablet output, d. H. at the then taking place within the housing displacement of the inner part, pushed against the bottom surface of the housing and thereby stretched. By relaxation, the return spring presses after completion of the dispensing operation, the inner part back to its original position.
• the inner part with the return spring of this tablet dispenser is currently made of POM (polyoxymethylene to DIN 7728 T1) and is relatively expensive. Corresponding attempts to replace the expensive POM by the cheaper PP (polypropylene according to DIN 7728 T1 and DIN 600001 T1), failed so far because the return spring loses its spring force during prolonged use and thus the reliability of the tablet dispenser is significantly reduced.
• the stated object is achieved with the characterizing features of claim 1, characterized in that the inner part of a respect to the material POM (Polyoxymethylene) less elastic material, for example made of PP (polypropylene) is made, and the return spring prevented by a certain combination of spring shape, spring material and mounting location on the inner part early release of the spring force.
• the return spring can in this case be made of the original material of the inner part and attached directly to the inner part (molded) or it can be made of a material deviating from the inner part material.
• the free end is supported against the bottom surface of the housing. Due to the lateral arrangement of the return spring of the spring travel or its deflection and thus the spring load over known spring arrangements is significantly reduced.
• it may have at least at one end two mutually connected angularly arranged legs, so that at this end two spring elements are effective.
• such spring elements are arranged between a lower step surface of the inner part and the bottom surface of the housing, wherein case by case can be completely dispensed with an attachment.
• Possible spring elements which can be used here for resetting the inner part are, for example: cylinder springs made of POM (polyoxymethylene), steel springs, foam elements, elements made of a thermoplastic elastomer (TPE), but also other elastic materials not mentioned here Spring shapes are selectable as long as they are usable for resetting the inner part and can be used inside the tablet dispenser.

Since the distance between the step surface 17 and the bottom surface 22 and thus the length of the return spring 14 is large, there may be the disadvantages described when using PP as spring material.
• FIGS. 2 and 3 the attachment location for the return springs 14a, 14b made of PP is arranged significantly closer to the bottom surface 22.

This spring is secured with two legs 14g 'on the lower step surface 17 of the inner part 10, while its lower end, formed by a circular portion, is punctiformly supported against the bottom surface 22. Due to its geometry, this return spring 14g is a highly elastic alternative to the previously described rod or leaf-shaped return springs.
