The tablet dispenser shown in Figure 1 has a housing 1 and a cover 3 which can be used therein and a base part 20 on. The housing 1 advantageously has an externally smooth, Technically favorable, preferably cylindrical Form of space and suitably consists of plastic.

From the overview of Figures 1 to 4 it can be seen that the housing has a slide 10 passing through it axially has a tablet 41 when actuated the passage opening 21 in the bottom part 20 with the help of the Dispensing end arranged feed organ 15 conveyed out becomes.

The slide 10 has one in at the upper end Connecting element 5 of the cover 3 can be clipped on Actuating rod 11 on. With this is the slider with the Lid 3 non-positively and positively connected, the lid 3 with a curvature 4 upwards soft-elastic plastic as a resilient return element is trained. The slide 10 has at the bottom one tablet 41 each and an adequate one Passage opening 21 penetrable in the bottom part 20 trained allocation member 15, and has the bottom part 20 one formed with a passage opening 21 between a passage position with the release of the Passage opening 21 and a locked position under lock and key of the passage opening adjustable rotary closure 30.

This twist lock 30 can for easy handling on the Outside diameter of the housing 1 above with a handy Knurling 31 be formed and its angle of rotation is through Stopper can be limited. However, these are in the interest of better overview not shown and can by the specialist in can be realized in any known manner.

As can be clearly seen from FIGS. 2 and 4, the Slider 10 at the lower end of the operating rod 11 in one roughly semicircular on the inside wall of the housing in a small amount Distance along, an upper one in the housing Storage space 22 defining, inclined downwards Intermediate floor 23 above, with a vertical apron 24 continues against the bottom part 20 and in cooperation with a spaced from the housing inner wall vertical guide 25, as best shown in FIG. 4 one can see one of lateral guide webs 26 or 27 limited funnel-shaped chute 28 forms, one the webs 26 on the guide 25 and the other web 27 below Formation of the allocation organ 15 arranged on the apron 24 is.

How to see the synopsis of Figures 2 and 4 further leaves, the apron 24 is on both vertical sides and the Intermediate floor 23 with its upper semicircular boundary little clearance is formed from the housing inner wall. In addition, the apron 24 points in the area of the allocation member 15 with formation of shoulders 16 and 17 on both sides next to one middle slider 18 recesses on the shoulders 16, 17 as stop stops for limiting the vertical Axial movement of the slide 10 relative to the outlet opening 21 are trained. From Fig. 2 it can also be seen that the Allotment member 15 the shape of a spoon in vertical Alignment.

Figure 3 shows a view from below and in an enlarged view Representation of the bottom part 20 within the inner wall of the Housing 1. As can be seen from Fig. 4, is the bottom part 20 clipped into the housing 1. It is a twist lock 30 formed and has the passage opening 21. she has the basic shape of a rectangle with a bevelled outer one Edge and sits to the other side in a slot 19 away. These serve for the passage of the apron 24 with it arranged allocation organ 15.

By turning the screw cap 30 by actuating the Knurling 31 are two positions of the twist lock reached, namely the position shown on the left in FIG. 3, in which the passage opening 21 in accordance with the arrangement of the apron 24 and the allocation member 15 is brought, so that these parts when pressed on the lid 3 at vertical Push through movement of the slide 10, then one in Allotment organ 15 contained tablet 41 after passage of the Allotment member 15 falls out through the opening 21 individually. At the Snap back due to restoring force of the cover 3 slips another tablet 41 into the one that is initially returning empty Allotment member 15, and the process can be as described be repeated.

By an expedient structure of the dispenser according to the invention in a preferably rotationally symmetrical design could the lower housing area the bottom part 20 as a twist lock 30 be formed. This makes the donor in the Delivery condition secured by the twist lock 30 so is set that the opening to the position of the slide 10th twisted and thus closed. This is simultaneous the slide 10 in its vertical movement possibility locked. The twist lock must now be used for dosing 30 can be turned back to the stop, creating the opening 21a, Fig. 3 in the outlet area of the allotment member 15 of the Slider 10 comes and the dispensing process can take place. After if desired, the twist lock 30 can be used to complete it turned back again and thus the slide 10 in his Movability locked and the passage opening 21st be closed.

The rotary lock 30 prevents the cover 3 from being pressed on - which is only assembled after filling the dispenser - one Dosing because the slide 10 due to clipping the rod 11 into the connecting element 5 of the cover 3 seeks to deflect the necessary force downwards, whereby an actuation in the sense of a dosing process would be done. In the locked position when the twist lock is installed this is prevented. In addition, the twist lock 30 at the same time a transport lock if the donor is in filled condition is delivered without outer packaging. By a Stacking in the box can then result in an unwanted donation process not be triggered.

FIG. 4 shows at a close distance above the twist lock 30 a cover plate 32, which ensures that the Passage opening 21 in the closed position 21a, Fig. 3 is completely covered from the inside, so that a Hermetic closure of the bottom part 20 results. By the Turning away the passage opening 21 below the metering member 15 results in the penetration of dirt particles or Splash preventing cap. There is still the possibility of opening the donor Passage opening 21 until the first use of the Tablet dispenser with a removable security label keep airtight.

The design of the cover 3 is particularly useful for the dispenser as a flexible spring, whereby after the Push through due to the restoring force of the material Slider 10 is withdrawn and the next Donation process can be carried out. Because of this flexible cover 3 needs in the slide area of the dispenser no additional spring to be attached. This gives the possibility of making the entire device uniform To manufacture plastic, which is disposal and recycling of the emptied donor significantly improved. Farther there is the possibility with the flexible cover 3 upper housing area clean for the entire service life seal and thus the ingress of dust or To prevent splash water and / or moisture absorption to avoid the tablets.

The tablet dispenser is convenient, uncomplicated to manufacture and assemble and is therefore suitable for a Inexpensive, occasionally fully automated mass production. In this respect, the invention optimally solves the problem at the beginning task.
