Abstract
The invention relates to a sealing cap (2) for a dispensing container (1), said sealing cap having a sealing slide (3), which can be displaced between a sealed position and an open position, a valve membrane (17) being employed in the open position. The aim of the invention is to provide a sealing cap with a simple construction that is reliable. To achieve this, the valve membrane (17) is held in the sealing slide (3) and can be displaced with the latter between the sealed position and the open position.
Description
Sealing Cap for a Dispensing Container The invention relates to a closure cap for a discharge container, the closure cap having a closure slide which can be displaced between a closed position and an open position, with a valve diaphragm being active in the open position.
DE 43 43 031 A1 has disclosed a closure cap which can be associated with a discharge container and the closure slide of which is moved by a driver of a rotary handle . The rotary handle runs in a transverse slot of the closure slide, which can move linearly between the closed position and the open position.
For details as to the configuration and association of a valve diaphragm, reference should be made to a German patent application bearing the application number 102 18 363.5. This diaphragm is curved in the shape of part of a sphere and consists of elastic, sealing material.
A slotted arrangement formed, for example, in the diametral, produces a lip-like valve function.
Given knowledge of these details, the invention is i based on the object of forming a structurally simple, operationally reliable closure cap of the generic type.
This object is achieved firstly and substantially by a closure cap having the features of claim 1 in which it is provided that the valve diaphragm is held in the closure slide and can be displaced between the closed position and the open position with the closure slide.
A structurally simple closure cap which is advantageous in use is achieved as a result of a configuration of this nature. The closure slide brings the valve diaphragm to the outlet of the discharge container and moves it away again as part of the opposite movement, in which position the closure function is then active.
The overall assembly functions as a sliding cover. The valve diaphragm can easily be connected to or even formed integrally on the closure slide. For details as to the means of connection, reference should be made to the German patent application cited above.
The subject matters of the further claims are explained below with reference to the subj ect matter of claim 1, but may also be of importance in their independent wording. For example, with a view to satisfying the demand for a reliable closed position, the structural refinement consists in the closure slide having, associated with the closed position; a closure diaphragm. This may be the base body outlined above, but simply in unslotted form. Its elasticity and flexibility represent ideal conditions for the desired sealing closure. A compact overall form is achieved if, furthermore, the procedure involves the valve diaphragm and the closure diaphragm being disposed next to one another in the closure slide in the sliding direction of the closure slide, with the valve membrane being disposed on that side of the closure diaphragm which is remote from the free end of the closure slide. In this way, the closure slide acts as two functional parts.
This moreover opens up the option of logical operation, making it highly unlikely that the valve diaphragm will be held closed. The user will preferably exert a sliding displacement action in the region of the free end. Furthermore, it is proven advantageous if, in the closed position of the closure slide, the valve diaphragm is located congruently with respect to an associated recess in the cap. This not only prevents unnecessary deformation or rolling of the valve diaphragm in the at-rest position, but also opens up the possibility of a latching aspect. The closure slide, as it were, becomes a snap-action means.

For example, with a view to satisfying the demand for a reliable closed position, the structural refinement consists in the closure slide having, associated with the closed position; a closure diaphragm. This may be the base body outlined above, but simply in unslotted form. Its elasticity and flexibility represent ideal conditions for the desired sealing closure.

In this way, the closure slide acts as two functional parts.
This moreover opens up the option of logical operation, making it highly unlikely that the valve diaphragm will be held closed. The user will preferably exert a sliding displacement action in the region of the free end. Furthermore, it is proven advantageous if, in the closed position of the closure slide, the valve diaphragm is located congruently with respect to an associated recess in the cap. This not only prevents unnecessary deformation or rolling of the valve diaphragm in the at-rest position, but also opens up the possibility of a latching aspect. The closure slide, as it were, becomes a snap-action means.
The invention then relates to a closure cap for a discharge container, the closure cap having a closure slide, which can be displaced between a closed position and an open position, with a valve diaphragm being active in the open position, and as a refinement to this closure cap proposes that a closure diaphragm is held in the closure slide and can be displaced between the closed position and the open position with the closure slide. The valve diaphragm is in this case stationed in the cap and the closure diaphragm, which in practice acts as a stopper, moves over it in such a manner as to form an opening or a sealing closure. In this context, it is possible to make operational use of the abovementioned flexibility of the diaphragms.
In both configurations, it has proven useful for the valve diaphragm, at least in the open position of the closure slide, to have, associated with its central region, an underside support. The said support is likewise disclosed by the German patent application (application number 102 18 363.5), the content of disclosure of which is hereby incorporated in its entirety, partly with a view to incorporating features of this application in claims of the present application. The support, which is attached via webs, also functions as an impact protection means, so that the liquid substance which is to be discharged cannot burst through uncontrollably. The support is disposed in a fixed position in the cap which accommodates the closure slide. Furthermore, it is proposed that the closure diaphragm be formed to be completely closed, in the sense that for example no air compensation takes place across it. Furthermore, at the top side a cover part of the closure slide engages over the closure diaphragm. This cover part functions as a protective shield for the sensitive closure member. The cover part has an additional function, in that the cover part has a finger recess on the outer side. This suggests correct actuation of the closure cap in the opening and closing directions. The finger recess approximately corresponds to the size of a fingertip of the human hand. It is preferable for the closure slide to be displaced linearly. It will be apparent that the basis of the movement may also be an arcuately linear displaceability. In either case, it is furthermore advantageous if, in the open position of the closure slide a free end of the closure slide projects freely beyond the associated edge of the cap. This can be used as an indication of the open position having been established. This is because an optically-visually perceptible projection of this nature is considered to interfere with the exterior. It may also become hooked onto other objects being carried. However, the user tends to clear the obstacle out of the way so that the closure cap is correctly closed again. Furthermore, it is provided that the closure slide is guided in a slot guide in the cap at one or both longitudinal edges. In this way, it is possible to achieve a further means of producing a defined stop limitation. The part of a slot guide of this type on 'the closure slide side is provided by the measure whereby the closure slide, to interact with the slot guide, has individual, separate sliding-block projections. The corresponding distance between the sliding-block projections provides l sufficient displaceable movability. For this purpose, the further configuration is such that the closure slide, by means of the slot guide, in the open and/or closed position is recessed with respect to a position outside the open or closed position. In other words:
the closure slide, in the event of a change of position, is, under control of the slot guide, lifted, displaced and lowered again. This protects the sealing bodies in the form of the diaphragms, which are curved in the manner of spherical caps toward the sealing seat surface, the valve diaphragm and the closure diaphragm.
Finally, it should also be noted that in the open position of the closure slide the closure diaphragm is located congruently with an associated recess in the cap. Therefore, in this case too the advantage is achieved that the closure diaphragm, in the at-rest position, is not subject to any deforming or rolling forces. Rather, a suitable yielding space is present.
Finally, it is also proposed that one or both recesses be closed in form.
The subject matter of the invention is explained in more detail below with reference to an exemplary embodiment illustrated in the drawing, in which:

The subject matter of the invention is explained in more detail below with reference to an exemplary embodiment illustrated in the drawing, in which:

Fig. 9 shows a vertical section through the closure cap with discharge container, showing the closed position, Fig. 10 shows a corresponding section, illustrating an intermediate position, and Fig. 11 shows the open position of the closure cap in vertical section.
At its topside, the discharge container 1 illustrated carries a closure cap 2. The Latter is used for the controlled discharge of contents in the form of a liquid substance, The control member is a closure slide 3. The closure slide 3 can be displaced between a closed position and an open position. The closed position is illustrated in Figure 1, and the open position is illustrated in Figure 6.
The closure side 3 is guided in a linearly displaceable fashion, at its side faces, in a cap 4 of the closure cap 2.
The sliding direction ~is in the longer axis of the cap 4, which is oval in cross section. The discharge container l, which is realized as a squeezable bottle, has a corresponding cross-sectional form. The discharge container is at least partially collapsible, The cap 4 of the closure cap 2 is associated with a neck 5 by way of a sealing plug-fit connection. A
projection 6 is used for this purpose. This projection proceeds from a cover portion 7, which is recessed with respect to the end of the closure cap 2, of the cap 4.
.. CA 02534232 2006-O1-30 _ 7 _ The recessed cover portion 7 forms, at the top side, the base 8 of a guide passage 9 for the closure slide 3.
The projection 6 is a type of hollow pin. In the center, it leaves clear an outlet 10 for the liquid substance.
In its free end region, the projection 6, which is integrally joined to the cover portion 7, ends in the form of a dome, with a view to centering the orientation of the cap 4 during assembly. The dome is composed of curved, convexly rounded tabs 11. .
The cap 4 is retained by means of a latching ring 12, which likewise leads from the cover portion 7 and is supported at holding arms. This latching ring 12 ultimately moves over - widening out as it does so -and engages beneath - returning to its original state as it does so - a latching bead 13 on the lateral wall of the neck 5. For further details of this form of retention, reference should be made to DE 198 24 714 A1.
The side region or surrounding area of the neck 5, i.e.
a shoulder 14 of the discharge container 1, is held in place by a peripheral wall 15 of the cap 4. The edge of the cap 4 is fitted, with plug limitation, onto a wall offset 16, forming a shoulder, of the discharge container 1. The peripheral wall 15 is realized as a double walls the inner wall surrounds a non-round, step-like pedestal of the neck toward the shoulder 14.
The outer wall is of matching contour.
In the open position of the closure slide 3, a self-closing valve diaphragm 17 is active (cf. Fig.
11). The valve diaphragm 17 is held in the closure slide 3 and can be displaced therewith between the _ g _ closed position (Figure 9) and the open position (Figure 11).
Furthermore, it can be seen that the closure slide 3 has, associated with the closed position, a closure diaphragm 18.
Figure 7 provides an isolated reproduction of the valve diaphragm 17, and Figure 8 does the same for the closure diaphragm 18. Both diaphragms are pieces which are geometrically identical in form. As has already been mentioned above, they are curved in the shape of segments of spheres and consist of elastomeric material. Accordingly, they provide a sealing action and have a flexibility which is fully restored after deformation.
Whereas the closure diaphragm 18 is completely closed in form, in accordance with its intended use, the valve diaphragm 17 has an aperture. This aperture is a slit 19 made in the diametral. This slit opens up in the event of appropriate pressure conditions' in the substance which is present, in the manner of a lip, and closes again when the pressure ceases.
.l The valve diaphragm 17 and the closure diaphragm 18 are disposed next to one another in the closure slide 3 in the sliding direction of the closure slide 3. They can be fixed by edge clamping of the diaphragm body, which has a circular contour. Alternatively, however, connection by adhesive bonding can also be carried out, or they may even be associated using the two-component injection-molding process. Latching via a ring frame is even conceivable.
The closure slide 3 runs in the guide passage 9, which is open on the right-hand side, as seen in the drawing.
The valve diaphragm 17 is therefore disposed on that side of the closure diaphragm l8 which is remote from the free end 3' of the closure slide 3. The said guide passage 9 is of greater length, as seen in the sliding direction, than the slide 3 accommodated therein.
In the closed position of the closure cap 2, the said free end 3' of the closure slide 3 is recessed toward the inside of the passage with respect to the edge 4' of the cap 4 at that location. In the open position (Figure 6) 'of the closure slide 3, by contrast, the free end 3' of the closure slide 3 projects beyond the associated edge 4' of the cap 4. The (albeit only moderately) freely protruding end position can serve as an optical-visual indicator of the open position having been adopted. The corresponding projection is indicated by reference symbol U.
In the closed position of the closure slide 3, the valve diaphragm 17 is located congruently with respect to an associated dished region 20 in the cap 4, more precisely in the lowered cover portion 7. The curvature of the valve diaphragm 17 is oriented toward the discharge container l, i.e. faces downward. The said dished region 20 adopts a curvature in the same direction, so that the free curvature portion of the valve diaphragm 17 is accommodated without deformation in the recess 20, which provides space for it.
The valve diaphragm 17 is located in the region of a top-side depression 21 in the closure slide 3. The center of this hollow portion of the closure slide 3 has a passage opening 22. In the open position of the closure cap 2, this opening is in flow communication with the slit 19 and also with the outlet 10 which is connected to the contents of the discharge container 1.
This represents the nozzle.
Once it has been displaced into the open position of the valve slide 3, the downwardly curved valve diaphragm 17 is under an active central support.
The support, which is positioned accordingly in the central region, is a disc 23 which is curved so as to , , match the diaphragm. This disc 23 or plate is seated on radially oriented webs 24. These can be lengthened by a directional offset and have spring properties, i.e. can lift off the underside of the valve diaphragm 17, in the event of suitable pressure conditions, together with disc 23. In the opposite direction, the disc 23 functions as an impact wall iri front of the slit 19.
Figure 2 provides a more detailed insight into the i configuration in this respect. In structural terms, accordingly, the procedure is for the support or disc 23 to be disposed in a fixed position in the cap 4 which accommodates the closure slide 3. The disc 23 circumscribes the inner edge of the outlet 10.
The spaces between the webs 24, i.e. the surrounding region of the disc 23 as far as the outer edge of the outlet 10, are available for the flow of medium through them in the open position and are held closed in the closed position, and can also be used for air compensation.
__) Referring now to the closed position, Figure 9, it can be seen that the closure diaphragm 18 has a cover part 25 of the closure slide 3 engaging over it on the top side. The cover part 25 has a top-side hollow, the size of which is such that a finger recess 26 is produced on the outer side of the closure slide 3.
The closure diaphragm 18, which keeps the through-flow path closed in the closed position, moves into a.type of parking region, formed at the base 8 of the cap 4, in the open position of the closure cap 2.
Specifically, in the open position of the closure slide 3, the closure diaphragm 18 is located congruently with respect to a hollow 27 in the cap 4 which is spatially associated with the diaphragm. Tt is of a similar form to the hollow 20, i.e. is curved in the same direction toward the closure diaphragm 18. Therefore, even in the open position there is no deforming load exerted on the closure diaphragm 18. A certain play can be provided.
Here too, it is possible to utilize a type of latching which defines the limit position.
In this context, it should also be noted that the disc 23 which has been explained, together with the webs 24 holding it, are oriented so as to match a corresponding recess contour, as is evident from the drawing.
The closure slide 3 is guided in a slot guide 29 of the cap 4 at one or both of its longitudinal edges 28.
Guidance on both sides is preferably applied. The guiding length of the slot guides 29 takes account of the demand for linear travel of the closure slide 3.
Sliding-block projections 30 constitute the guiding counterpart on the closure slide 3. These projections are located at a distance from one another in the sliding direction. In spatial terms, they extend approximately on a diametral, located transversely with respect to the sliding direction, of the hollow 21 and of the finger recess 26, more specifically outward toward the free end 3' and offset slightly in the opposite direction with respect to the diametral. The sliding-block projections 30, which interact with the slot guide 29, are circular in cross section and on the underside are beveled approximately at an angle of 45°, as can be seen from the drawing, in order to allow a clip association between the closure slide 3 and the guide passage 9.
At the side remote from the free end 3' of the closure slide 3 there is, in the longitudinal center plane of the closure slide 3, a pin 31 which is configured similarly to a projection and is likewise beveled and which, in the closed position of the closure cap 2, enters a matching opening 32 in the guide passage 9.
This provides protection against the arrangement being lifted out. The latter means may be configured with a snap action. The snap-action force can be overcome deliberately if it is desired to do so.
As can be seen from Figure 2, two separate sections of the slot guide 29, located one behind the other, are realized in the parallel longitudinal walls of the guide passage 9. Their profile is practically trapezoidal in contour. On the underside, a strip 33 formed integrally on the base 8 with a longitudinal orientation is partly responsible for determining the trapezoidal profile of the sections. In each case only one sliding-block projection 30 is associated with each section. The trapezoid flanks form drive portions which have a lowering action and have end-side, horizontal pockets 34. The overall assembly acts in such a way that the closure slide 3, in the open and/or closed position, is lowered by means of the slot guides 3 compared to a position outside the said open or closed position. The switching, raised intermediate position is revealed by Figure 10. In that position, the sliding-block projections 30 pass through the top side of the sections of the trapezoidal slot guide 29. This leads to a limited, vertically oriented raising of the guided closure slide 3; so that the convex part of both the valve diaphragm 17 and the closure diaphragm 18 can move into the next or other functional position with a gentle lifting action. This means that there is no grating movement, even if, as can be seen from Figure 2, the hollow 21 and the outer edge of the outlet 10 are still surrounded by an annular wa11.35 which ends in a tip at the top, functioning as a rotationally symmetrical sealing strip with respect to the soft-elastic diaphragms 17, 18.
Functioning is, in summarized form, as follows:
;' CA 02534232 2006-O1-30 Through displacement of the closure slide 3 in the direction of the edge 4', the valve diaphragm 17 is moved into a congruent position with respect to the outlet 10. The discharge passage is clear as a result.
The dispenser, which is configured as a stand-alone unit, is turned upside-down. The application of a pressure to the discharge container 1 causes substance, indicated by the shaded structure, to be discharged. At the same time, the closure diaphragm 18, which previously held the outlet 10 sealed shut, has been moved into a parked position, i.e. has been brought to the recess 27.
By applying the technical details explained above, it is also possible to effect a configuration which is such that a closure diaphragm 18 is held in the closure slide 3 and can be displaced between the closed position and the open position with the closure slide.
The valve diaphragm 17 is then seated in the region of the outlet 10, disposed in a fixed position in the base 8 of the cap 4.

In its free end region, the projection 6, which is integrally joined to the cover portion 7, ends in the form of a dome, with a view to centering the orientation of the cap 4 during assembly. The dome is composed of curved, convexly rounded tabs 11. .
The cap 4 is retained by means of a latching ring 12, which likewise leads from the cover portion 7 and is supported at holding arms. This latching ring 12 ultimately moves over - widening out as it does so -and engages beneath - returning to its original state as it does so - a latching bead 13 on the lateral wall of the neck 5. For further details of this form of retention, reference should be made to DE 198 24 714 A1.
The side region or surrounding area of the neck 5, i.e.
a shoulder 14 of the discharge container 1, is held in place by a peripheral wall 15 of the cap 4. The edge of the cap 4 is fitted, with plug limitation, onto a wall offset 16, forming a shoulder, of the discharge container 1. The peripheral wall 15 is realized as a double walls the inner wall surrounds a non-round, step-like pedestal of the neck toward the shoulder 14.
The outer wall is of matching contour.
In the open position of the closure slide 3, a self-closing valve diaphragm 17 is active (cf. Fig.
11). The valve diaphragm 17 is held in the closure slide 3 and can be displaced therewith between the _ g _ closed position (Figure 9) and the open position (Figure 11).
Furthermore, it can be seen that the closure slide 3 has, associated with the closed position, a closure diaphragm 18.
Figure 7 provides an isolated reproduction of the valve diaphragm 17, and Figure 8 does the same for the closure diaphragm 18. Both diaphragms are pieces which are geometrically identical in form. As has already been mentioned above, they are curved in the shape of segments of spheres and consist of elastomeric material. Accordingly, they provide a sealing action and have a flexibility which is fully restored after deformation.
Whereas the closure diaphragm 18 is completely closed in form, in accordance with its intended use, the valve diaphragm 17 has an aperture. This aperture is a slit 19 made in the diametral. This slit opens up in the event of appropriate pressure conditions' in the substance which is present, in the manner of a lip, and closes again when the pressure ceases.
.l The valve diaphragm 17 and the closure diaphragm 18 are disposed next to one another in the closure slide 3 in the sliding direction of the closure slide 3. They can be fixed by edge clamping of the diaphragm body, which has a circular contour. Alternatively, however, connection by adhesive bonding can also be carried out, or they may even be associated using the two-component injection-molding process. Latching via a ring frame is even conceivable.
The closure slide 3 runs in the guide passage 9, which is open on the right-hand side, as seen in the drawing.
The valve diaphragm 17 is therefore disposed on that side of the closure diaphragm l8 which is remote from the free end 3' of the closure slide 3. The said guide passage 9 is of greater length, as seen in the sliding direction, than the slide 3 accommodated therein.
In the closed position of the closure cap 2, the said free end 3' of the closure slide 3 is recessed toward the inside of the passage with respect to the edge 4' of the cap 4 at that location. In the open position (Figure 6) 'of the closure slide 3, by contrast, the free end 3' of the closure slide 3 projects beyond the associated edge 4' of the cap 4. The (albeit only moderately) freely protruding end position can serve as an optical-visual indicator of the open position having been adopted. The corresponding projection is indicated by reference symbol U.
In the closed position of the closure slide 3, the valve diaphragm 17 is located congruently with respect to an associated dished region 20 in the cap 4, more precisely in the lowered cover portion 7. The curvature of the valve diaphragm 17 is oriented toward the discharge container l, i.e. faces downward. The said dished region 20 adopts a curvature in the same direction, so that the free curvature portion of the valve diaphragm 17 is accommodated without deformation in the recess 20, which provides space for it.
The valve diaphragm 17 is located in the region of a top-side depression 21 in the closure slide 3. The center of this hollow portion of the closure slide 3 has a passage opening 22. In the open position of the closure cap 2, this opening is in flow communication with the slit 19 and also with the outlet 10 which is connected to the contents of the discharge container 1.
This represents the nozzle.
Once it has been displaced into the open position of the valve slide 3, the downwardly curved valve diaphragm 17 is under an active central support.
The support, which is positioned accordingly in the central region, is a disc 23 which is curved so as to , , match the diaphragm. This disc 23 or plate is seated on radially oriented webs 24. These can be lengthened by a directional offset and have spring properties, i.e. can lift off the underside of the valve diaphragm 17, in the event of suitable pressure conditions, together with disc 23. In the opposite direction, the disc 23 functions as an impact wall iri front of the slit 19.
Figure 2 provides a more detailed insight into the i configuration in this respect. In structural terms, accordingly, the procedure is for the support or disc 23 to be disposed in a fixed position in the cap 4 which accommodates the closure slide 3. The disc 23 circumscribes the inner edge of the outlet 10.
The spaces between the webs 24, i.e. the surrounding region of the disc 23 as far as the outer edge of the outlet 10, are available for the flow of medium through them in the open position and are held closed in the closed position, and can also be used for air compensation.
__) Referring now to the closed position, Figure 9, it can be seen that the closure diaphragm 18 has a cover part 25 of the closure slide 3 engaging over it on the top side. The cover part 25 has a top-side hollow, the size of which is such that a finger recess 26 is produced on the outer side of the closure slide 3.
The closure diaphragm 18, which keeps the through-flow path closed in the closed position, moves into a.type of parking region, formed at the base 8 of the cap 4, in the open position of the closure cap 2.
Specifically, in the open position of the closure slide 3, the closure diaphragm 18 is located congruently with respect to a hollow 27 in the cap 4 which is spatially associated with the diaphragm. Tt is of a similar form to the hollow 20, i.e. is curved in the same direction toward the closure diaphragm 18. Therefore, even in the open position there is no deforming load exerted on the closure diaphragm 18. A certain play can be provided.
Here too, it is possible to utilize a type of latching which defines the limit position.
In this context, it should also be noted that the disc 23 which has been explained, together with the webs 24 holding it, are oriented so as to match a corresponding recess contour, as is evident from the drawing.
The closure slide 3 is guided in a slot guide 29 of the cap 4 at one or both of its longitudinal edges 28.
Guidance on both sides is preferably applied. The guiding length of the slot guides 29 takes account of the demand for linear travel of the closure slide 3.
Sliding-block projections 30 constitute the guiding counterpart on the closure slide 3. These projections are located at a distance from one another in the sliding direction. In spatial terms, they extend approximately on a diametral, located transversely with respect to the sliding direction, of the hollow 21 and of the finger recess 26, more specifically outward toward the free end 3' and offset slightly in the opposite direction with respect to the diametral. The sliding-block projections 30, which interact with the slot guide 29, are circular in cross section and on the underside are beveled approximately at an angle of 45°, as can be seen from the drawing, in order to allow a clip association between the closure slide 3 and the guide passage 9.
At the side remote from the free end 3' of the closure slide 3 there is, in the longitudinal center plane of the closure slide 3, a pin 31 which is configured similarly to a projection and is likewise beveled and which, in the closed position of the closure cap 2, enters a matching opening 32 in the guide passage 9.
This provides protection against the arrangement being lifted out. The latter means may be configured with a snap action. The snap-action force can be overcome deliberately if it is desired to do so.
As can be seen from Figure 2, two separate sections of the slot guide 29, located one behind the other, are realized in the parallel longitudinal walls of the guide passage 9. Their profile is practically trapezoidal in contour. On the underside, a strip 33 formed integrally on the base 8 with a longitudinal orientation is partly responsible for determining the trapezoidal profile of the sections. In each case only one sliding-block projection 30 is associated with each section. The trapezoid flanks form drive portions which have a lowering action and have end-side, horizontal pockets 34. The overall assembly acts in such a way that the closure slide 3, in the open and/or closed position, is lowered by means of the slot guides 3 compared to a position outside the said open or closed position. The switching, raised intermediate position is revealed by Figure 10. In that position, the sliding-block projections 30 pass through the top side of the sections of the trapezoidal slot guide 29. This leads to a limited, vertically oriented raising of the guided closure slide 3; so that the convex part of both the valve diaphragm 17 and the closure diaphragm 18 can move into the next or other functional position with a gentle lifting action. This means that there is no grating movement, even if, as can be seen from Figure 2, the hollow 21 and the outer edge of the outlet 10 are still surrounded by an annular wa11.35 which ends in a tip at the top, functioning as a rotationally symmetrical sealing strip with respect to the soft-elastic diaphragms 17, 18.
Functioning is, in summarized form, as follows:
;' CA 02534232 2006-O1-30 Through displacement of the closure slide 3 in the direction of the edge 4', the valve diaphragm 17 is moved into a congruent position with respect to the outlet 10. The discharge passage is clear as a result.
The dispenser, which is configured as a stand-alone unit, is turned upside-down. The application of a pressure to the discharge container 1 causes substance, indicated by the shaded structure, to be discharged. At the same time, the closure diaphragm 18, which previously held the outlet 10 sealed shut, has been moved into a parked position, i.e. has been brought to the recess 27.
By applying the technical details explained above, it is also possible to effect a configuration which is such that a closure diaphragm 18 is held in the closure slide 3 and can be displaced between the closed position and the open position with the closure slide.
The valve diaphragm 17 is then seated in the region of the outlet 10, disposed in a fixed position in the base 8 of the cap 4.
All the features disclosed are (inherently) pertinent to invention. The disclosure content of the 1 associated/appended priority documents (copy of the prior application) is hereby incorporated in its entirety in the disclosure of the present application, partly with a view to incorporating features of these documents in claims of the present application.
