Definitions

• the invention relates to a tablet dispenser with a tubular protective housing, in which longitudinal guides for tablets which can be inserted in the form of a column-like stack and a spring-loaded pressure stamp for one end of the stack of tablets are provided in a guide shaft, which pressure stamp the tablets along the longitudinal guides to one in the area of the other end of the stack supports ejectors, by means of which the tablets guided in its area between side guides can be individually pushed out transversely to the longitudinal direction of the stack.
• Such tablet dispensers are preferably used for tablets that can be easily assembled into a columnar stack, for example tablets with a prismatic or cylindrical casing.
• a main area of application for the tablet dispenser is for refreshment tablets and pastilles of rectangular, prismatic basic shape which lie flat against one another in the stack.
• the longitudinal guides for the tablet stack are formed in a separate drawer, which carries the ejector at its end protruding from the protective housing, the drawer being open only after the tablets are pushed out, so that the tablet stack is pulled out of the tablet Side can be inserted.
• pressure is accommodated even inside the tablet guide shaft. which supports the pressure plunger, which is guided longitudinally in the drawer and in the housing.
• the compression spring has no matter whether the drawer is filled or not the endeavor to pull the drawer into the protective housing up to a stop and therefore fulfills a double function, since when the drawer is pushed in it pushes the pressure stamp and thus the stack of tablets after the removal of each tablet by the tablet height to the ejector end.
• the known tablet dispenser has several disadvantages. Above all, relatively expensive, complicatedly shaped springs must be used, in the case of tablet dispensers for rectangular-prismatic tablets, for example coil springs with screw threads lying on the jacket of a prism, and during assembly it is necessary to precisely define the three parts of the protective housing, loading and spring Lay the layers together and insert the pressure stamp under the catches of the protective housing. A part of this assembly takes place under at least in part between the spring and the loading of the spring, so that this spring forces the previously folded parts apart when inattentive.
• the assembly can only from
• Tablet dispensers of the type in question are predominantly pronounced mass articles in which the assembly costs have so far made up a large part of the total costs.
• the spring provided is not only complex to manufacture, but also has other decisive disadvantages. When the drawer is pulled out, the spring is given a relatively large preload. Due to manufacturing errors in the tablet dispenser, normal wear and tear during use, or also due to willful damage, it can happen that the ejector stamps are no longer properly at the tube end of the protective housing due to the catches is held, but jumps out when the drawer is pulled out, the stamp then being thrown out and the spring also jumping out in an uncontrollable path. Such a protruding spring can cause injury to the face or eyes, so that the previous tablet dispensers are also of concern with regard to this risk and product liability.
• the object of the invention is to provide a tablet dispenser of the type mentioned at the outset, which is easier to manufacture and assemble than the known tablet dispensers, has a high level of operational reliability and, in particular, reliably prevents the pressure stamp and spring from jumping out uncontrollably.
• a part of the invention is to create a tablet dispenser that can be quickly and hygienically loaded with the tablets.
• the main task is solved in that the spring loading the pressure stamp is accommodated in the housing in a spring shaft arranged next to the guiding and receiving shaft for the tablets, and loads a guide piece guided in the spring shaft, which is connected to one of the two shafts connecting one of the two shafts Longitudinal slot led arm, a support rib or bracket carries the pressure stamp. - t -
• the spring is housed protected in the embodiment according to the invention and can have a simple, easily producible shape. It becomes possible to mount the spring with the guide piece and the pressure stamp separately with the spring largely relaxed, so that this installation is not difficult and can also be carried out in automatic machines. In contrast to the known design, the pressure stamp does not have to fill out the entire guide cross-section for the tablets, so that there is also no danger that abrasion and other tablet residues impair the proper functioning of the pressure stamp and the spring.
• the spring shaft is closed at the ejection end of the housing and has a closable insertion opening for the guide piece and the spring at its opposite end, the guide slot preferably being open into this insertion opening, so that the stamp with the arm and the guide piece formed in one piece and can be used together with the spring.
• a permanent, secure closure can be provided for the insertion opening, grafting, sealing or pressing of the opening edges after the assembly or combinations of these measures, among other things, being introduced inseparably.
• a magazine is preferably provided for the tablet stack, which magazine is formed at the same time as part of a tablet pack and has the tablet guides, can be inserted interchangeably into the tablet guide shaft of the housing and has an opening for the pressure stamp on at least one longitudinal end , at least at the other longitudinal end has lateral openings for the ejector engagement and the tablet ejection and in the use position directed towards the spring shaft
• the same openings are preferably provided at both ends of the magazine, so that the magazine can optionally be inserted with one end or the other pointing towards the ejector end.
• the magazine can be a plastic molded part or made of stronger metal foil, hard paper or the like. be formed, resulting in low manufacturing costs in mass production. If the magazine also forms part of the packaging, then further packaging costs are reduced compared to the previous type of packaging.
• the insertion of a magazine is much easier than the insertion of a stack of tablets, the tablets themselves not having to be touched during insertion and other handling, so that handling is much more hygienic than before. is going.
• the tablet guides of the magazine consist of longitudinal cutting edges or combs which project outwards on the inside of the magazine walls.
• the inside edges of the combs or cutters projecting into the interior of the magazine can be provided at least on two opposite magazine sides within the contour of the tablets, so that these combs or cutters at least when they are moved to the ejector into the tablets of the tablet Form the inserted tablet stack of guide grooves or grooves, which also contributes to the safe guidance.
• the tablets in the stack are prevented from tipping over, even if the pressure stamp acts only on the bottom tablet with a small contact surface.
• the magazine When the tablets are inserted, the magazine preferably has between the channels lying within the tablet outline. ten or cutting resiliently deformable walls.
• This embodiment makes it possible to fill the magazine with the stack of tablets via a side opening replacing a longitudinal wall, the combs or cutting edges resiliently resting against the tablets, holding the tablets in place and securing them against changes in position and against falling out through the insertion opening during transport .
• the magazine can be inserted into the protective housing from the ejector-side housing end, and the ejector attached to the housing itself can be pivoted away from the corresponding opening for the insertion process on the housing, for. B. hinged, the ejector is secured in the working position by latching.
• Another possibility is to provide a lateral insertion opening for the magazine in the housing and to retract the pressure stamp by manipulating the guide piece or the spring when the magazine is inserted so far that the pressure stamp with the stack end pointing away from the ejector in Intervention can be brought. It can be provided that a back part of the magazine closes the side housing opening and, for example, supplements the housing to form a handle.
• a further development of the tablet dispenser according to the invention provides that, as is known per se, a tray which can be pulled out from the end of the protective housing and which has a pull-out limit is used for receiving the stack of tablets and which carries the ejector on its end protruding from the housing when the drawer is inserted the drawer has a lateral insertion opening for the tablet stack or the magazine and a guide slot for the plunger arm and that the drawer can be locked in the insertion position via a releasable brake lock.
• the input bring the tablets or the stack of tablets or the magazine in the usual way with the drawer pulled out of the protective housing.
• the brake lock consists of a resilient brake tongue which is or is formed in the area of the store end which can be inserted into the housing, in particular as part of a store provided there, and which has its free end with arching of the tongue against the presses the through-slot opposite the wall area of the housing provided and, similarly to an over-center lock, emerges from the bending position protruding into the drawer when the drawer is inserted into the housing when the drawer is pulled out
• This design of the brake lock is particularly simple, and according to the preferred embodiment, the tongue can be shaped together with the drawer when the drawer is made from the corresponding material.
• a further design simplification can be achieved in that the pressure stamp or support arm in its fully extended position protrudes from the housing with its underside by at least the spring play of the spring tongue formed from the end wall of the shop and having only a limited ability to bend, so that the store front wall and the spring pulls protruding downwards over the drawer (which assumes this position when the drawer is pulled out of the housing) form pull-out locks for the drawer.
