CLOSURE COVER FOR DOSING CONTAINER DESCRIPTION OF THE INVENTION
The invention relates to a closure cap for a dispensing container, wherein the closure cap comprises a slide that can be moved between a closed position and an open position, wherein a valve membrane is active in the open position. From DE 43 43 031 Al a closure cap can be detached which can be associated with a dispensing container whose closing slide is moved by a dragging of a rotary handle. The rotary handle slides in a transverse slit of the closing slide which can move in a linear direction between the closed position and the open position. With regard to the configuration and association of a valve membrane, reference is made to the German patent application under the procedure with the official reference: 102 18 363.5. It is bulged in the form of a spherical, flexible section and consists of elastic sealing material. A sectioning performed, for example, diametrically, produces a valve function in the manner of lips. In consideration of these specifications, the invention aims to form a closure cap of this kind of simple construction and reliable operation. The objective is achieved primarily and essentially with a closure cap having the features of claim 1, it being intended that the valve membrane is held in the closure slide and that it can be moved along with it between the position closed and open position. By means of such a configuration a closure cap of simple construction and offering an advantageous use is achieved. The closing slide places the valve membrane in the mouth of the dosing container and removes it in the opposite direction, this position then having the closing function effect. The whole set works like a sliding diaphragm. The valve membrane is easy to join with the closing slide respectively until it can be joined by injection molding. With regard to the means of the union, reference is made to the aforementioned German patent application. The objects of further claims are explained below in relation to the object of claim 1, but may also be significant in their independent wording. Thus, for example, the constructive improvement, in relation to producing a reliable closed position, consists in that the closing slide which is associated with the closed position comprises a closing membrane. This can be the basic body described in the foregoing, but without slit. Its elasticity and flexibility offer ideal conditions for the tried closure. A compact construction is achieved if. further proceeds in such a way that the valve membrane and the closing membrane are arranged next to one another in the direction of displacement of the closing slide, the valve membrane being disposed at the free end of the closing slide which is opposite the side of the closing membrane. The closing slide thus becomes a vehicle for two functional components. This also allows a 'logical operation which makes it unlikely that the valve membrane will be covered. The user will preferably grasp the region of the free end to slide it. It is further advantageous that the valve membrane is received in the closed position of the closing slide so as to cover an associated cavity of the cover. This avoids, in the rest position, not only unnecessary deformation in the sense of a flattening of the valve membrane, but also opens up the possibility of an attachment aspect. The closing slide acts, so to speak, as a ratchet. The invention also relates to a closure cap for a dispensing container, wherein the closure cap comprises a closing slide that can be moved between a closed position and an open position., since a valve diaphragm is active in the open position and it is proposed as an improvement that a closing diaphragm is held in the closing slide and can be moved together with it between the closed position and the open position. In this case, the valve membrane is located in the cover and the closing membrane passes over it in such a way that it acts practically as a stopper. In this it is possible to take advantage of the aforementioned flexibility for the operation. In both embodiments, it turns out to be useful, then, that the valve membrane, in any case in the open position of the closing slide, has a support on the lower face disposed in the middle region. The referred support can also be derived from the German patent application (reference 102 18 363.5). The object of this is incorporated in full content also for the purpose of including features of this application in claims of the present application. The support, joined by ribs, also functions as shock protection, so that an uncontrolled outflow of the liquid substance to be dosed can not occur. The support is arranged stationary in the cover that houses the closing slide. It is further proposed that the closure membrane be formed completely closed, in the sense that, for example, no pressure compensation is made therethrough. In addition, the closing membrane is covered on the upper face by a cover component of the closing slide. The latter functions as a protective shield for the sensitive closure organ. The cover component has an additional function, the cover component having a finger print on the outside. This suggests a correct operation of the closing cover in the direction of opening and closing. The finger print corresponds approximately to the size of a finger tip of the human hand. Preferably, the closing slide is displaced in the linear direction. Of course it is also possible that it can also be moved in the form of an arch. In one way or another, it is advantageous if a free end of the closing slide in the open position of the closing slide protrudes from the associated edge of the lid. This can be used to indicate that the open position has been presented. Such an overhang is certainly perceived as a distraction in terms of external appearance. It can also catch with other accompanying objects. In any case, the user is more likely to be inclined to eliminate the obstacle and, therefore, to close the closure cover correctly. Furthermore, it is provided that the closing slide is guided in a slide of the cover on one or both longitudinal edges. Thus it is possible to achieve an additional means of a defined stop. The part in the closing slide of such a guide guided by a collision is produced by the measure that the closing slide has individual lug studs separated from each other for reciprocal action with the sill. The corresponding distance of the lug studs allows an appropriate displacement mobility. For this, the other shaping is carried out in such a way that the closing slide is at a lower level relative to a position outside the open or closed position. In other words: the closing slide is lifted, displaced and again lowered guided by the slide. This protects the seal body made by the membranes, the valve membrane as well as the closing valve, bulging in the form of a cap towards the seal settling surface. Finally, it should still be noted that in the open position of the closing slide, the closing membrane is housed, covering it, in an associated print of the cover. In this way, the advantage is also presented here that the closing membrane is not exposed in the rest position to the deformation stresses, respectively, of beating. Rather, an appropriate space of diversion is offered. Finally, it is still proposed that one or both impressions be formed in a closed manner. The object of the invention is explained below in more detail by means of an exemplary embodiment also illustrated by drawing. In the following they show: Fig. 1 the closing lid associated with a dosing container, adopting the closed position, in perspective,

Closing seen from below, Fig. 5 this same in side view, Fig. 6 the dispensing container with sliding slide displaced in open position, again in perspective, Fig. 7 the valve membrane, in the same way of representation, Fig. 8 the closing diaphragm Fig. 9 a vertical section by the closure cap with dispensing container, showing the closing position, Fig. 10 a corresponding section, representing an intermediate position and Fig. 11 the open position of the closure cap in FIG. vertical section. The dosing container 1 has a closure lid 2 at the top. The latter serves for the controlled delivery of a content in the form of a liquid substance. The control member is a closing slide 3. The closing slide 3 can be moved between a closed position and an open position. Figure 1 shows the open position. The closing slide 3 is guided displaceably linearly in the front part in a cover 4 of the closing lid 2. The direction of travel lies on the longest axis of the lid 4, oval in cross section. The dosing container 1, which is embodied as a deformable bottle, has a corresponding cross-sectional contour. The dosing container may collapse at least in part. The cover 4 of the closure lid 2 is associated with a neck 5 in the manner of a plug connection with a sealing function. For this, a projection 6 is used. The latter starts in a cover section 7 of the cover 4 that is opposite the front end of the closure cover 2. The recessed cover section 7 forms on the upper face the floor 8 of a guide cube 9 for the closing slide 3. The shoulder 6 is a type of hollow pivot. This leaves a step 10 free for the liquid substance. The projection 6 that forms a single piece together with the cover section 7 ends in its domed free end region, the foregoing with a view to a centering alignment of the cover 4 during assembly. The dome is composed of flaps 11 bulged inwards, rounded in convex form. The fastening of the cover 4 is also carried out by means of a retaining ring 12 which also takes its start in the covering section 7 and which is supported by clamping arms. The latter passes through. on top - stretching out - and passing underneath - returning to its original size - finally a retaining bulge 13 in the wall surrounding the neck 5. With reference to additional details of this type of fastening, reference is made to DE 198 24 714 A1. lateral region, respectively the proximity of the neck 5, that is to say the step 14 of the dosing container 1, is kept closed by a covering wall 15 of the cover 4. The front edge of the cover 4 is seated in a wall projection 16 of the container 1 dispenser that forms a step as a stop. The enclosing wall 15 is constructed as a double wall; the inner wall comprises a non-round base, forming steps, from the neck to the step 14. The outer wall follows the contour. In the open position of the closing slide 3, a membrane 17 of automatic closing valve acts (Cf. figure 11). The valve diaphragm 17 is fastened to the closing slide 3 and can be moved together with it between the closed position (FIG. 9) and the open position (FIG. 11). It is further appreciated that the closing slide 3 has a closing membrane 18 which is associated with the closed position. The valve membrane 17 can be seen in an isolated representation in figure 7, the closing membrane 18 is thus shown in figure 18. Both membranes are components with the same geometrical shape. They are bulged, as mentioned in the preceding, in the form of a sphere section and consist of a material with rubber elasticity. They act, therefore, as seals and have a full recovery flexibility after deformation. While the closure membrane 18 is - according to its application purpose - completely closed, the valve membrane 17 has an opening. It is a slit 19 practiced diametrically. This is opened in the manner of lips, by governing appropriate pressure conditions in the adjacent substance and closes when the pressure disappears. The valve diaphragm 17 and the closing diaphragm 18 are arranged next to one another in the closing slide 3 in the direction of displacement of the closing slide 3. Its fixation can be practiced by tightening the edge of the membrane body having a circular contour. On the other hand it is also possible to make a bond with glue technique, also an association by means of two component injection method. Even a hooked by a circular frame is imaginable. The closing slide 3 slides in the guide cube 9 which, in the drawing, is open to the right. The valve membrane 17 is therefore arranged on the opposite side of the closing membrane 18 to the free end 3 'of the closing slide 3. The guide cube 9 referred to is of greater length in the direction of displacement than the slide 3 housed therein. In the closed position of the closing lid 2, the referred free end 3 'of the closing slide 3 abruptly retracts relative to the edge 4' beyond the lid 4 towards the inside of the hub. In the open position (FIG. 6) of the closing slide 3, in contrast, the free end 3 'of the closing slide 3 protrudes from the associated edge 4' of the cover 4. The final position, although it protrudes only moderately, it can serve as an optical indication that the open position has been reached. The corresponding protruding part is designated with the reference symbol Ü. In the closed position of the closing slide 3, the valve membrane 17 covers an associated impression 20 of the cover 4, more precisely of the recessed cover section 7. The convexity of the valve membrane 17 is oriented towards the dosing container 1, that is to say, it shows downwards. The aforementioned impression 20 has a convexity in the same direction, so that the free convexity section of the valve membrane 17 is received without deformation in the impression 20, giving it free space. The valve membrane 17 is located in the re of a groove 21 in the upper face of the closing slide 3. The center of this notch-shaped section of the closing slide 3 has a passage aperture 22. This is connected, in the open position of the closing lid 2, so as to allow the passage of liquid with the slit 19 and also with the passage 10 which is connected to the contents of the dosing container 1. She forms the mouthpiece. When displaced towards the open position of the closing slide 3, the downwardly convex valve membrane 17 has an active central support. In relation to the support positioned correspondingly in the middle re, this is a disk 23 bulged correspondingly to the membrane. This disc 23 or plate is seated on ribs 24 having radial orientation. These can be extended by directional displacement and are elastic, that is, they can be lifted together with the disc 23 of the lower face of the valve membrane 17 when appropriate pressure conditions prevail. In the opposite direction, the disk 23 functions as a stop wall in front of the slit 19. • FIG. 2 offers a more detailed view of the configuration of the above explained. As for the construction, the procedure has been carried out in such a way that the support respectively the disc 23 is stationary disposed in the cover 4 which houses the closing slide 3. Disk 23 circumscribes the inner edge of step 10. The interstices of the nerves 24, that is to say, the surroundings of the disk 23 up to the outer edge of the passage 10 allow the passage of the liquid in the open position and plug it in the closed position, and also serve for the compensation of atmospheric pressure. Referring to the closed position, figure 9, it can be seen that the closing membrane 18 is covered on its upper face by a cover element 25 of the closing slide 3. The cover element 25 has a notch on its upper face. This has a size such that a finger print 26 is obtained on the external part of the closing slide 3. The closure membrane 18 which covers the flow passage in the closed position is accommodated, in the open position of the closure lid 2, in a type of parking region, formed in the floor 8 of the lid 4. In the open position of the closing slide 3, the closure membrane 18 is housed, incidentally, covering an impression 27 of the cover 4 which is associated with it in a spatial sense. It is made in the form of an identical configuration as it exists in relation to the printing 20, that is to say; with a bulge in the same direction as the closing membrane 18. Thus, a load that deforms the closing membrane 18 is prevented from forming, even in the open position. You can foresee a certain game. In this way, a way to define the final position by retention can also be exploited. In this context it should also be noted that the aforementioned disc 23, together with the. nerves 24 that support it, have alignment according to a corresponding printing contour, as seen in the drawing.
The closing slide 3 is guided in a slide 29 of the cover 4 on one of its longitudinal edges or on both longitudinal edges 28. Preferably, a guide is used on both sides. The length on which the guide 29 guides takes into account the linear path required by the closing slide 3. The counterpart for the guiding technique in the closing slide 3 is provided by projections 30 of the wall studs. These are located at a distance from one another in the direction of travel. They extend spatially approximately in a diametrical line of the groove 21 and the finger impression 26 which is located in the transverse direction relative to the direction of travel, more precisely, slightly offset relative to the diametral line outwardly in the direction from the free 3 'end as well as in the opposite direction. The projections 30 of wall studs, acting reciprocally with the wall 29, have a circular cross section and, on their lower face as shown in the drawing, beveled at an angle of approximately 45 ° with respect to the association of clamping technique of the slide 3 of closure in the guide cube 9. On the side opposite to the free end 3 'of the closing slide 3 is located in the longitudinal central plane of the closing slide 3 a pivot 31 formed in the form of a projection, also bevelled, which penetrates into the closed position of the cover 2 of closing in an appropriate opening 32 of the guide hub 9. This produces an insurance against lifting. These latter means can be designed in the manner of a ratchet. The ratchet force can be overcome intentionally. As shown in Figure 2, two separate sections of the collets 29, which are located one behind the other, have been made in the parallel longitudinal walls of the guide cube 9. Its trace is made practically with a "trapezoidal" contour On the underside, a rib 33 formed on the 8th floor longitudinally participates in the determination of the trapezoidal trace of the sections Each section is associated with respectively only one 30 of the wall studs protrude The trapezoidal sides form guide sections with horizontal bags 34 in the end part that act towards, below, all this has the effect that the closing slide 3 is recessed, by means of the collar 29, in the open and / or closed position relative to a position outside the said open or closed position, the intermediate position, in transition situation, is detached from figure 10. In this, the projections 30 of wall studs pass through the upper side of the sections of the trapezoid collision 29. This has the effect of a limited elevation in the vertical direction of the guided slide 3, so that the convex part both of the valve membrane 17 and of the closing membrane 18 are passed over carefully so that they can be accommodated in the next one, respectively the other functional position. A rough path is not presented, even in the case, as seen in FIG. 2, that the notch 21 and the outer edge of the step 10 are additionally surrounded by an annular elevation 35 that forms a peak upwards and that it functions as a shutter nerve with rotational symmetry in relation to soft elastic membranes 17, 18. Summarized shortly, the function is as follows: By moving the closing slide 3 in the direction towards the edge 4 ', the valve membrane 17 is displaced to assume a position congruent with step 10. The delivery route, by therefore, it is free. The dispenser, configured as a flat bottom device, is moved to an inclined position. By exerting pressure on the dosing container 1, a substance marked by a striped weft emerges. Simultaneously, the closing membrane 18, which has the function of sealing in a sealed manner, has been moved to a parking position, that is to say, to the impression 27. Applying the technical circumstances explained, a mode can also be realized in the sense that a closing membrane 18 is fastened on the closing slide 3 and can be moved together with it between the closed position and the open position. The valve membrane 17 is then seated in the region of the passage 10 arranged in a stationary manner on the floor 8 of the cover 4. All the characteristics shown are essential (each one of them) for the invention. The content expressed in the associated / attached priority documents (copy of the previous application) is included in the manifestation of the application, also with the purpose of including characteristics of these documents in the claims of the present application.
