Description

The invention relates to a dispenser for single-portion dispensing of tablets, with a housing, a stroke-limited displaceable slide and a tablet storage room with a subsequent discharge shaft, end faces and profiled flanks being formed in a proportionally fixed manner on the housing and proportionally formed on the slide, and further in the Movable flank a compartment chamber is formed and a compartment finger assigned to the compartment chamber in the flank fixed to the housing.

A donor of this type is known from DE-OS 34 16 681. There the tablet standing in the compartment chamber, that is to say immediately ready for dispensing, is flush with the underside of the dispenser. To this extent there is contamination with the footprint. Also, touching the dispenser cannot be excluded with certainty.

Another general problem with such donors is the achievement of safe isolation. The coincidence of several unfavorable factors such as mechanical stress on the tablets due to a longer dispensing period, splinter splinters, manufacturing tolerances of both the separating mechanism and the tablets can limit the reliability of dispensing, although a certain pre-order of the tablet portion immediately ready for dispensing is practiced. Self-locking also occurs, for example Bridge constellation of these dispensable tablets, so that the user repeatedly shakes the dispenser, which in turn significantly increases the risk of breakage, particularly in the case of tablets which are only weakly bound.

It is therefore an object of the present invention to provide a generic dispenser which is simple in terms of production technology and reliable in use in such a way that, on the one hand, the undesired free state of the tablet which is ready to be dispensed is avoided, but on the other hand an extremely gentle separation without the risk of pressing is ensured.

This object is achieved by the invention specified in claim 1.

The subclaims are advantageous developments of the dispenser according to the invention.

As a result of such a configuration, a generic dispenser of increased utility value is achieved: the result is a flawless, practically free-standing single delivery of the tablets. The user no longer needs to loosen the tablets by shaking them. Accordingly, the risk of breakage is significantly reduced. The hygienically questionable, partial release of the tablet ready to be dispensed with is also eliminated. The structural means are simple and expedient: for this purpose, the compartment finger is formed by a bottom tip of a first inclined surface, which is located on the top opposite the upper end of the compartment chamber, and that a second inclined surface is formed on the movable flank, which, starting at the upper end of the compartment chamber, extends upwards, continuously increasing the cross section of the delivery shaft. The realization of a first inclined surface not only brings about a gentle surface-tangent support for the tablet that is ready to be dispensed, but also holds this tablet in a larger size Distance to the stand area of the donor. The inadequate coverage explained thus ceases to exist. For this reason, the acceptance of such a donor is already increasing. But also the other elements of the solution combination explained create a gentle delivery and loosening transport of the tablets, whereby there are predominantly surface-tangent touch and guide systems in the output shaft profile. This makes the mechanical stress on the tablets bearable. Above all, the additional inclined surface in the area of the movable flank causes the penultimate tablet to be retained in a superimposed manner to dispense the tablet that is ready to be dispensed, on which the penultimate tablet is supported until the end, that is, until the first and second inclined surfaces make the lock-like slippage so narrow that the penultimate tablet is held back safely and, above all, from the use of non-press. The return movement, that is to say the closing of the compartment chamber, causes a slight, again gentle, upward displacement of the row of tablets extending in front of the compartment chamber. This and the fact that the cross section of the delivery chute increases continuously upwards (approximately to the size of one and a half times the tablet diameter), eliminates any possible bridge constellation of the tablets. The hygienic bottom closure is optimized in that the drainage slope of the compartment chamber and the first inclined surface in the basic position of the dispenser form a funnel which is almost closed at the bottom in cross section. The funnel contour conveys an even greater distance from the stand area of the dispenser. It also proves to be advantageous that the second inclined surface and the first inclined surface, when actuated, form in cross section a funnel that is closed to the diameter of a tablet. However, this surface orientation converging downwards also has the advantage of greater independence from the tablet size, that is to say, for example, tablets reduced in size by abrasion are subject to the exact same exact separation as freshly filled tablets. Removed tablets are lying only a little deeper, i.e. closer to the funnel base than a larger diameter. An advantageous, practically a zigzag-like row of tablets creates configuration with simple means in that the housing-fixed outlet shaft boundary surface adjoining the first inclined surface upwards and opposite in the unactuated state of the second inclined surface then runs vertically (perpendicular to the standing surface of the donor). The following details have proven to be favorable design relationships with regard to the profiled flanks of the output shaft: The first inclined surface and the second inclined surface each include an acute angle alpha or beta with a shaft center plane, the angle beta being smaller than alpha. In addition, the outlet slope forms an acute angle with the shaft center plane, which is larger than the angle alpha. The latter encourages the roll-out movement when the row of tablets is already falling, even with a certain tendency to eject. Furthermore, it is proposed to a dispenser, whose slider floor on the storage space side fills up about two thirds of the storage space cross section, that the slider is connected to the actuation button via a central actuating shaft and that the side wall of the storage space is formed by the housing. This leads to the fact that the majority of the stock is included in the lowering and return movement of the slide, which leads to an additional advantageous loosening effect, which is particularly welcome with slightly sticky tablets. In this respect, the storage space consists of wall sections which are movable relative to one another, the side wall being the resting part. The central position of the actuating shaft leads to a favorable introduction of force when actuating the dispenser. From a stabilization point of view, it proves advantageous that the actuating shaft has a cross-shaped cross section. Without increasing the amount of material, projections project radially into the filling material. It also proves to be stabilizing view as expedient to let two cross legs merge into a strip dividing the slider floor on the storage room side. This also results in an advantageous network or transition area between the rather narrow actuation shaft and the area-wide floor of the dispenser. The corresponding configuration is further optimized by means of a structural measure in such a way that the slide bottom is valley-shaped, that the bar in the valley bottom runs downward, in alignment with the delivery shaft. This creates two inlet areas, that is, a good distribution of the supply to the collecting shaft extending underneath, which lies between the delivery shaft and the storage room. Furthermore, it is advantageous that the slide below the slide bottom, aligned with the bar, carries a vertical wall which leads with its peripheral longitudinal edge to the corresponding inner surface of the housing. Finally, it is advantageous that the housing is closed on the bottom side, with the exception of an opening for the slide head, by a transverse wall, which forms the support for a return spring formed as a leaf spring and formed on the slide. In order to take the problem of safety in use into account despite high reliability of use, especially towards those in need of protection, we continue to work on a dispenser for single-portion dispensing of tablets, with a housing, a stroke-limited relocatable slide and a tablet storage room with subsequent dispensing shaft, with end faces and profiled flanks are formed in a manner fixed to the housing and formed in part on the slide to form a compartment chamber, it is proposed that locking elements which can be disengaged against the spring preload essentially perpendicularly to its direction of displacement are designed for engagement in securing recesses in the housing in the unactuated state. The portioning can only be carried out with emphasis on the actuation combination of shifting the spring projections and then moving the slide. Complicating and not without for children or older people The fact that pressure operations in two different planes and three directions are required is also understandable. Structurally, the procedure is advantageously such that the latching elements are formed by cut-out tabs of a pot-shaped slide actuating button. The slide head designed in this way practically has a triple function: the pot shape can be used to achieve a top end of the dispenser; there is also the intended use as an actuation button; in addition, there is the function of the parts which form the child lock. In order to further differentiate the actuation, the invention also proposes that the locking elements are formed at diametrically opposite points. In this way, for example, the thumb and middle finger are required to displace the locking elements, the actuation in the direction of dislocation being carried out with the index finger. Furthermore, it proves to be advantageous that concave actuating grooves are formed on the tabs in the convex transition region from the pot bottom to the pot wall of the actuating button. These parts prove to be particularly resilient, so that correspondingly higher actuation forces have to be applied. The selected concave shape also ensures that the fingers of the actuating hand are protected against slipping. Finally, it is also proposed that the actuating throat end of the actuating button on the cup wall side protrude into a protruding bead which projects into the area of the imaginary extension of the housing wall. In this way, a limit stop or an additional limit stop can be realized with appropriate stroke coordination, so that the stop forces do not exclusively go into the slide.

The housing 1 of the dispenser shown, which forms a storage space V with its larger volume fraction, has a circular cylindrical cross section. It is taller than it is wide. The storage room V holds a number of tablets 2. This content is issued individually via a slide 3, which can be moved vertically and incorporated in a stroke-limited manner.

The slider 3 forms with a slider bottom 4 the lower end of the storage space V, together with a bottom section 5 on the housing side. Both run downwards inclined in the direction of a flat V-shaped collecting shaft 6, which is followed by a downward-extending discharge shaft 7.

The upper end of the storage space V forms an easily accessible actuating button 8. The latter is connected to an actuating shaft 9 which extends from the top of the slide bottom 4 and passes through the housing 1 centrally.

The slide bottom 4 takes up about two thirds, in the illustrated embodiment even three quarters of the storage space cross section. The corresponding adaptation to the circular cross-section with the cross-sectional dimension going beyond the diametral leads to a favorable guidance of the slide 3 in this area. On the upper side, the axial guidance takes over the pot-shaped actuation button 8. The latter forms a connecting piece 10 for the corresponding end of the actuation shaft 9 on the inside of its upwardly convex ceiling. A snap connection can be selected. The locking projections 11 sit on the actuating shaft 9. The counter-locking means in the form of an annular groove 12 are located on the inside of the connecting piece 10.

The slide 3 is in the direction of its basic position (Fig. 1) under spring loading. The corresponding spring force is applied by a leaf spring 13 which is molded onto the underside of the slide, the latter being, as can be seen in the drawing, arched slightly sagging. It can have a pretension, for example by being formed in the extended position in an approximately extended position parallel to the actuating shaft 9. On the slide bottom side, it is rooted (13) in the vicinity of the collecting shaft 6. Its free end is supported on a transverse floor 15 slightly drawn in from the stand edge 14. The latter forms the bottom end of the dispenser mechanism. As a result, the slide 3 is mounted from above.

As can be seen in FIG. 4, the actuating shaft has a cross-shaped cross section. Two cruciform legs, designated 9 ', are rooted in an upwardly facing strip 16 which divides the sliding floor 4 on the storage compartment side 4. This leads to a stable technical connection between the actuating shaft 9 and the sliding base 4. In stabilizing terms, it also proves advantageous that On the underside, a vertical wall 17 which is congruent with the strip 16 is formed, which slides with its peripheral longitudinal edge over the inner surface of the housing 1 or is supported on it, and possibly also projects into a U-guide 30 below.

Fig. 5 can be seen particularly clearly that the slide bottom 4 is valley-shaped. The flank angle of the upwardly diverging floor halves is 30 °. The bar 16 runs in the valley bottom, that is, in the diametral. Your protruding height above the valley floor corresponds approximately to the radially measured depth of the cross leg 9 '. In addition to the valley-like shape, the slide bottom 4 is also aligned in a downward direction, that is to say the valley bottom slopes downward in the direction of the collecting shaft 6 lying transversely in front of it and the output shaft 7 adjoining it.

The basic position of the slide 3 is defined by a lateral projection 19, which has the spring-side edge 20 of an opening 21 in the transverse base 15.

The individual portioning of the tablets 2 is based on a special profile of the dispenser mechanism, that is to say of the dispensing shaft 7. In this, the disk-shaped tablets enter in an upright arrangement, one above the other. They take the zigzag course shown, for example, in FIGS. 8-11. The output shaft 7 is formed by an end face a of the housing 1 and a parallel end face b of the slider 3, on which end faces the circular broad surfaces of the tablets 2 are supported, as well as profiled flanks c and d that are fixed to the housing and partially formed by the slider. The edge c is fixed to the housing, the other is realized on the slide side; the profiled flanks face the cylindrical outer surface of the tablets. The movable profiled flank d, that is, that of the slide 3 below, forms a compartment chamber A, which is closed in the basic position of the dispenser mechanism and which compartment chamber A is assigned a compartment finger F formed on the flank c fixed to the housing.

With regard to the profiling of the flank-forming flanks, the procedure is such that the compartment finger F is formed by a bottom-side tip 22 of a first inclined surface I, which starts on the upper side approximately on a horizontal line opposite the upper end 23 of the compartment chamber A. In contrast, on the movable flank d there is a second inclined surface II, which, starting at the height of the upper end 23 of the compartment chamber A, extends upwards, and there continuously enlarges the entrance of the output shaft 7.

The compartment chamber A, which is recessed like a throat in the upper part, merges via a corner enclosing 90 °, that is to say in the manner of a nose-shaped projection 24, into the adjoining, obliquely arranged second inclined surface II. The throat bears the reference numeral 25. Its curvature corresponds at least to the circular shape of the wall of the tablet 2. Downward, a progressive slope III attaches to the throat 25 in a stepless transition.

The run-off slope III of the compartment chamber A and the first inclined surface I in the basic position of the dispenser (FIGS. 1 and 8), seen in cross section, form a funnel T1 which is almost closed at the bottom. Because of the flank support, the tablet has a sufficient vertical distance from it, avoiding any contact with the stand area St of the dispenser.

The second inclined surface II and the first inclined surface I then form a funnel T2 closed below the diameter dimension D of a tablet when the dispenser is actuated, as seen in cross section. This leads to a gentle restraint of the penultimate tablet. The immediately dispensable tablet 2 'is released. It rolls on the slope III (see FIG. 11).

The upper end region of the output shaft 7 is, as far as the profiled flank c is concerned, designed in such a way that the housing-fixed output shaft delimitation surface 26, which adjoins the first inclined surface I upwards and is opposite to the second inclined surface II in the unactuated state, perpendicular to the installation surface ST of the Spenders runs. At most, for reasons of injection technology, it can be slanted to open slightly. Both the boundary surface 26 and the first inclined surface I and the second inclined surface II and basically also the run-off slope III are all of the same length, the length fraction of III still being obtained from part of the throat 25. Each of the lengths corresponds approximately to the clear distance of the entrance of the output chute 7. The clear distance corresponds approximately to one and a half times the tablet diameter.

As far as the bevels of the inclined surfaces are concerned, it is advantageous to align them (cf. FIG. 8) in such a way that the first bevel I with a shaft center plane E-E encloses an acute angle Alpha of approximately 25 °. In contrast, the second inclined surface II of the inclined surfaces I, II converging downward includes an acute angle Beta of 20 °. The elongated flank line intersects the tip 27 of the bottom of the compartment chamber A. By contrast, this bottom or the run-off slope III defining it forms an angle gamma of approximately 50 ° with the vertical shaft center plane E-E.

The end face a is part of a vertical wall 28 lying in the form of a segment of a circle, which merges on the upper side into the above-mentioned sloping bottom section 5, which itself, like the two end sections of the vertical wall 28, is rooted in the wall of the housing 1, that is to say by injection molding with it Stand together. The movable vertical wall 29 of the slider 3 opposite the stationary vertical wall 28 represents the end face b on the slider side and the profiled flank d on the slider side.

The function of the dispenser is, briefly summarized, as follows: By exerting a force in the direction of the arrow P, the slide 3 is lowered against the spring force in a stop-limited manner. As a result, the head 3 'of the slide 3 increasingly enters a free-standing position of the compartment chamber A on the bottom side. The individual phases can be seen particularly clearly from FIG. 8. The tablet 2 'supported in the funnel T1 and immediately ready for dispensing is first displaced transversely by means of the first inclined surface I in the direction of the throat 25 of the compartment chamber A forming a rear free space. This relative displacement leads to a displacement of the tablets 2 extending over it, which are supported on the flank side and in a zigzag sequence, and thus to a loosening. Along with the downward displacement of the slider 3, the nose-like corner 24 of the second inclined surface II increasingly comes in the direction of the tip 22 of the compartment finger F (cf. FIG. 9). Further lowering increases the distance between the tip 27 of the slide head 3 'and the tip 22 of the compartment finger F and overlapping to a narrowing of the clear width between the corner 24 of the slide head and the opposite inclined surface I. Even before the dispensing opening is so wide open that the immediately ready-to-dispense tablet 2 'can leave the ramp-like slope III, the second funnel T2 has formed in a tablet-friendly manner, which holds back the penultimate tablet 2 without any tendency to be pressed. Rather, the downwardly converging inclined surfaces I and II enable the retained penultimate tablet to retreat due to the shape of the funnel in the event of a horizontal component. When the slide is released, the second inclined surface II moves upward, enlarging the funnel opening, so that the penultimate tablet can now fall into the compartment chamber A when the diameter-corresponding free space is reached.

The upward or backward displacement of the slide 3 also leads to a further loosening effect, which extends into the Collection shaft 6 continues, etc. The selected bevels lead to a complete output of the contents of the donor.

All parts can be made of polystyrene; the length of the leaf spring 13 favors this, so that the relatively expensive POM material can be dispensed with.

The exemplary embodiments according to FIGS. 12 to 15 and 16 to 20 are basically of the same structure. The reference numbers are therefore transferred analogously, but without extensive textual repetitions.

With regard to the second exemplary embodiment (FIGS. 12 to 15), there is a slight change in the compartment geometry. As far as the bevels of the inclined surfaces are concerned, it is now advantageous, taking into account the tablet size shown (FIG. 13), that the first inclined surface I with the shaft center plane E-E includes an acute angle alpha of approximately 40 °. The second inclined surface II of the downwardly converging inclined surfaces I, II, on the other hand, includes an acute angle Beta of approximately 18 ° to said reference plane. The extended flank line also intersects the tip 27 of the floor of the compartment chamber A. This floor or the run-off slope III defining it, on the other hand, encloses an angle gamma of approximately 75 ° with the vertical shaft center plane E-E.

In the third exemplary embodiment (FIGS. 16 to 20), the angle gamma is also approximately 75 °, beta is 18 ° and alpha is approximately 25 °.

As far as the further structural modifications are concerned, according to the second exemplary embodiment the housing 1 or its wall continues downward beyond the transverse floor 15. The corresponding projection dimension corresponds to the stroke dimension of the slide 3. This means that in the actuating position the projection 19 is no longer in a visible front position occurs. The space 31 which is created by the protrusion and is open at the bottom could accommodate a pot part, for example, so that the tablet falls into such a pot part. The tablet can be brought to the destination without any contamination.

In addition, in the second exemplary embodiment, the vertical wall 17 of the slide is only realized rudimentarily, in particular is no longer used to guide the slide 3. It only has a stabilizing function with respect to the slide bottom 4.

At about the point at which the guide 30 is realized in the first embodiment, there is now a pair of parallel spaced vertical strips 32 in the two additional embodiments added.The latter are molded onto the housing 1 and, with their upward-facing end face 33, form a height stop for the Slider 3, to limit the movement for the delivery stroke. The limitation in the opposite direction also occurs here through the projection 19 of the slide 3. The latter occurs in the spring-loaded basic position of the slide against the underside of the transverse base 15. In contrast, the underside of the slide base 4 interacts with the end face 33.

Childproofing is then implemented in the third exemplary embodiment. For this purpose, the slide 3 forms latch elements 34 that can be disengaged essentially perpendicular to its direction of displacement against spring preload. These are protrusions 35 which are oval in cross section and which engage in safety recesses 36 of the housing 1 from the inside in the disengaged position, that is to say in the unactuated state (cf. FIG. 16).

The locking elements 34 are formed by cut-out tabs 37 of the cup-shaped slider head, that is, actuation button 8. Two tabs 37 are realized in the cylindrical pot wall. These are such that the Locking elements 34 are positioned at diametrically opposite points. The vertically aligned, parallel separating cuts which divide the tabs 37 from the remaining wall part of the pot have the reference symbol 38. They are spaced approximately a finger's width apart and extend into the bottom, or rather the ceiling, of the pot-shaped structure.

The transition area between the ceiling or pot bottom and the pot wall of the actuation button 8 is rounded convexly and designated by 39. As far as into this convex transition region 39, the ends of the separating cuts 38 there and even a little further extend into the slightly curved ceiling.

In the root region of the tabs 37, the locking elements 34 each form an actuating groove 40 on the outside. These concave actuation grooves 40 thus lie in the convex transition area 39. It is not merely a matter of indentations of the wall zone of the transition area facing inward in the pot; rather, the actuating throats 40 still extend into a protruding limiting bead 41 on the cup wall side, so that there is a full finger insert and the fingers cannot slide off the actuating key 8 forming the slide head, taking into account the main direction of actuation of the push button. As can be seen in FIG. 16, the protruding limiting bead 41 protrudes significantly beyond the general outer diameter of the actuation button 8, namely into the region of the imaginary, upward extension of the housing 1. The axial distance between the upper, horizontal end face of the housing 1 and the lower flank of the limiting bead 41 corresponds to the stroke-limited actuation stroke of the slide 3, so that the limiting bead 41 can also perform the function of an additional limiting stop or can also act alone.

As can be seen in FIG. 17, the actuating throat 40 has an elliptical outline with the longer ellipse axis located in the horizontal.

The securing recess 36 is also elliptical, likewise with the longer ellipse axis aligned horizontally. The recess can, for example, also be made exclusively from the inside of the housing 1, ie it cannot be designed as an opening. The size of the securing recess 36 takes into account the space required for the protrusions to be angled in and out, so that no jamming occurs.

The release actuation of the childproof lock takes place by exerting a pressure in the direction of the bottom of the actuating throats 40. Since the latter are located more in the root region of the flaps 37 cut free at the end, the actuation must be carried out in a manner that is quite intentional. The projections 35 lift out of the locking recesses 36 holding them in a blocking manner. Then the slide 3 can be moved in the direction of the arrow P, which leads to the dispensing of a tablet, in the manner explained in detail above.

When the actuation button 8 is released, the slide 3, which is under spring loading, moves back into its basic position. For this purpose, the force of the leaf spring 13 is dimensioned greater than the friction values of the latching elements 34 which are frictionally connected to the inner wall of the housing. In the basic position, they snap, ie their projections 35, back into the securing recess 36. The out-of-round shape of the guided slide 3 ensures that the latching is always exactly again. A slight bias of the tongues 37 over the outer diameter of the actuation button 8 can be selected, but is not necessary. The simple restoring force in the original pot shape of the actuating button 8 leading in the housing 1 is sufficient.

As can also be seen in the two further exemplary embodiments, the upper side of at least the sloping sliding bottom 4 is provided with teeth 42 which promote the entry of the tablets into the V-shaped collecting shaft 6. The tooth gaps wedge in the direction of the rise of the sliding floor 4. The greatest gap depth results in the plane of the vertical wall 29 of the slide 3.

A similar toothing can, as can be seen from FIG. 18, also be located on the upper side of the bottom section 5 on the housing side.

The actuating throat 40 is roughened. The roughening can be realized by horizontal grooving.

21 and 22 show an alternative embodiment of the slide. This embodiment of the slide 3 is characterized by a return spring 13, which is designed as a circular closed profile. The return spring 13 in the form of a closed circle is formed directly behind the end wall b. This return spring of the special design has the effect of a double spring. A strong spring effect can be achieved with a small space requirement.

In the embodiments according to FIGS. 12 and 15 it can be seen that 8 stiffening ribs 50 are formed below the actuation button. These stiffening ribs 50 have a bevel 51 which widens with respect to the housing 1. This bevel is of particular importance with regard to the assembly of the dispenser, which is to be carried out at least in part as a blind assembly.

All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
