Definitions

• End cap for a dispensing container
• the invention relates to a closure cap for a dispensing container, the closure cap having a closure slide which can be displaced between a closure position and an opening position, a valve membrane being effective in the opening position.
• DE 4343031 AI shows a closure cap that can be assigned to a dispensing container, the closure slide of which is moved via a driver of a rotary handle.
• the turning handle runs in a transverse slot of the slide valve, which can be moved linearly between the closed position and the open position.
• valve membrane With regard to the design and assignment of a valve membrane, reference is made to a German patent application, registered under the official file number: 102 18363.5. It is curved in the manner of a spherical section, flexible and consists of elastic, sealing material. A slit, for example in the diametral, results in a lip-like valve function.
• the invention has set itself the task of constructing a generic closure cap structurally simple and reliable.
• the user will prefer to reach into the area of the free end in a sliding manner. It also proves to be advantageous that in the closed position of the slide valve, the valve membrane lies in overlap with an assigned depression of the cap. This not only avoids unnecessary deformation or flexing of the Ventumem- bran, but also opens up a rest technical aspect.
• the slide gate becomes a snap.
• the invention then relates to a closure cap for a dispensing container, the closure cap having a closure slide which can be displaced between a closed position and an open position, a valve membrane being effective in the open position, and further suggests that a closure membrane be held in the closure slide is and can be shifted with this between the closed position and the open position.
• the valve membrane is stationed in the cap and is opened or overflowed by the closing membrane, which acts practically as a stopper.
• the flexibility of the membranes mentioned can be used operationally.
• valve membrane in any case has a support on the underside in the open position of the closure slide, assigned to its central region. Said support also emerges from the German patent application (file number 102 18363.5). Their subject matter is included in full, also for the purpose of including features of this application in claims of the present application.
• the support which is connected via webs, also acts as impact protection, so that the liquid substance to be dispensed cannot break through in an uncontrolled manner.
• the support is arranged in a stationary manner in the cap receiving the slide.
• the sealing membrane be completely closed, in the sense that, for example, there is no air compensation.
• the top of the closure membrane is covered by a cover part of the closure slide.
• the latter acts as a protective shield for the sensitive closure organ.
• the ceiling part is one Additional function given that the ceiling part has a finger recess on the outside. This suggests proper actuation of the cap in the sense of opening and closing.
• the finger recess roughly corresponds to the size of a fingertip of the human hand.
• the locking slide is preferably displaced linearly. Of course, it can also be based on a genuinely linear relocability. Either way, it is also advantageous that in the open position of the closure slide, a free end of the closure slide projects cantilevered from the associated edge of the cap. This can be used as an indication of the open position that has occurred. A protrusion that is more visually and visually perceived is more of a nuisance with regard to the exterior.
• the locking slide is guided on one or both longitudinal edges in a setting of the cap.
• a further means of a defined stop limitation can be achieved in this way.
• the part of such a slide guide on the slide valve side is provided by the measure that the slide slide has individual, separate slide block projections for interaction with the slide.
• the corresponding spacing of the sliding block projections opens up sufficient mobility.
• the further embodiment is made such that the closing slide is lowered by means of the link in the opening and / or closing position compared to a position outside the opening or closing position.
• the locking slide When changing the position, the locking slide is raised, moved and lowered again in a gate-controlled manner. This protects the sealing body in the form of the domes, which are curved like a cap towards the sealing seat surface, the valve membrane and the sealing membrane. Finally, it should be noted that in the open position of the slide the closure membrane lies in overlap with an assigned depression of the cap. There is also the advantage here that the sealing membrane is not exposed to any deforming or walking forces in the rest position. Rather, there is a suitable alternative space. Finally, it is suggested that one or both troughs be closed.

• the control element is a locking slide 3.
• the locking slide 3 can be shifted between a locking position and an opening position, hi FIG. 1 shows the locking position, FIG. 6 shows the opening position.
• the closure slide 3 is guided on the end face in a cap 4 of the closure cap 2 in a linearly displaceable manner.
• the direction of displacement is in the longer axis of the cap 4, which is oval in cross section.
• the dispensing container 1, which is realized as a squeeze bottle, has a corresponding cross-sectional shape.
• the dispensing container is at least partially collapsible.
• the cap 4 of the closure cap 2 is assigned to a neck 5 by means of a sealing plug connection.
• a projection 6 is used for this purpose. The latter goes from a ceiling section 7 of the cap 4 which is lowered relative to the front end of the closure cap 2.
• the lowered ceiling section 7 forms the top 8 of the bottom of a guide shaft 9 for the locking slide 3.
• the dome is composed of domed, convexly rounded tabs 11.
• the cap 4 is tied up via a latching ring 12 which also extends from the ceiling section 7 and is held on support arms with carried latching ring 12. The latter overflows - widening - and engages under - resetting - finally a latching bead 13 on the outer wall of the neck 5.
• a latching ring 12 which also extends from the ceiling section 7 and is held on support arms with carried latching ring 12. The latter overflows - widening - and engages under - resetting - finally a latching bead 13 on the outer wall of the neck 5.
• the side area or the area surrounding the neck 5, that is to say a shoulder 14 of the dispensing container 1, is held closed by a jacket wall 15 of the cap 4.
• the front edge of the cap 4 is plug-in on a shoulder-forming wall projection 16 of the dispensing container 1.
• the jacket wall 15 is realized as a double wall; the inner wall includes a non-circular, step-shaped base of the neck towards the shoulder 14.
• the outer wall conforms to the contours.
• a self-closing valve membrane 17 is effective (cf. FIG. 11). The valve membrane 17 is held in the slide valve 3 and can be moved with it between the closed position (FIG. 9) and the open position (FIG. 11).
• closure slide 3 assigned to the closure position, has a closure membrane 18.
• valve membrane 17 is shown in an isolated representation from FIG. 7, and the closure membrane 18 is shown in FIG. 8.
• both membranes are geometrically identical pieces. As already mentioned above, they are curved in the form of spherical sections and consist of rubber-elastic material. Accordingly, they exert a sealing effect and have flexibility that fully resets after deformation.
• valve membrane 17 While the closure membrane 18 is designed to be completely closed in accordance with its intended use, the valve membrane 17 has an opening. It is a slot 19 exerted in the diametral. The lip opens in the pending substance at appropriate pressure conditions and closes again when the pressure ceases.
• valve membrane 17 and the closure membrane 18 are arranged next to one another in the displacement direction of the closure slide 3 in the closure slide 3. Your fixation can be exerted under the edge of the circular membrane-shaped membrane body. On the other hand, an adhesive connection can also be carried out, even an assignment in the two-component spraying process. Even locking over a ring frame is conceivable.
• the slide 3 runs in the guide shaft 9, which is open on the right side in the drawing.
• the valve membrane 17 is thus arranged on the side of the closure membrane 18 facing away from the free end 3 ′ of the closure slide 3.
• Said guide shaft 9 is of greater length in the direction of displacement than the slide 3 accommodated therein.
• valve membrane 17 In the closed position of the closure slide 3, the valve membrane 17 is in overlap with an associated depression 20 of the cap 4, more precisely the lowered ceiling section 7.
• the curvature of the valve membrane 17 is aligned with the dispensing container 1, that is to say pointing downward.
• Said trough 20 takes a curvature course in the same direction, so that the free curvature section of the valve membrane 17 is accommodated in the space-giving trough 20 without deformation.
• the valve membrane 17 lies in the region of a dent 21 on the top of the closing slide 3.
• the center of this dented section of the closing slide 3 has a passage opening 22.
• this is in flow connection to the slot 19 and further to the passage 10, which is connected to the contents of the dispensing container 1. She puts the mouthpiece.
• the downwardly curved valve membrane 17 is under an effective central support.
• the correspondingly positioned support in the center area it is a correspondingly curved disc 23.
• This disc 23 or plate is seated on radially oriented webs 24.
• Figure 2 provides closer insight into the related design.
• the procedure is accordingly such that the support or disk 23 is arranged in a stationary manner in the cap 4 receiving the slide 3.
• the disk 23 circumscribes the inner edge of the passage 10.
• the spaces between the webs 24, that is to say the area surrounding the pane 23 up to the outer edge of the passage 10, are capable of flowing through in the open position and are kept closed in the closed position, and furthermore are useful for air balance.

• the ceiling part 25 has an upper side corrugation. It is of such a size that a finger recess 26 is achieved on the outside of the locking slide 3.
• the closure membrane 18, which keeps the flow path in the closed position, is accommodated in a kind of parking area in the open position of the closure cap 2, formed on the bottom 8 of the cap 4.
• the closure slide 3 is in fact covered by the closure membrane 18 in relation to a trough 27 of the cap 4 which is spatially assigned to it. It is made in a configuration as it exists with respect to the trough 20, that is to say in a curvature in the same direction as the closure membrane 18. Thus, even in the open position there is no deforming load on the closure membrane 18. A certain amount of play can be provided.
• a type of detent defining the end position can also be used here.
• the locking slide 3 is guided on one of its longitudinal edges or on both longitudinal edges 28 in a link 29 of the cap 4.
• a guide on both sides is preferably used.
• the leading length of the links 29 takes into account the linear stroke requirement of the slide 3.
• the filling counterpart on the closing slide 3 is provided by sliding block projections 30. These are spaced apart from one another in the direction of displacement. They extend spatially a little bit on a diametral of the dent 21 and the finger recess 26 lying transversely to the direction of displacement, more precisely outwards towards the free end 3 'and slightly offset in the opposite direction to the diametral.
• the sliding block projections 30, which interact with the backdrop 29, are circular in cross-section and on the underside, as can be seen from the drawing, approximately at an angle of 45 °, for the purpose of assigning the slide slide 3 in the guide shaft 9 by means of clips.
• two successive, separated sections of the link 29 are realized in the parallel longitudinal walls of the guide shaft 9. Their course is practically made in a trapezoidal contour.
• a strip 33 formed longitudinally on the base 8 also determines the trapezoidal course of the sections.
• Only one sliding block projection 30 is assigned to each section.
• the trapezoidal flanks form lowering control sections with horizontal pockets 34 at the ends. The whole has the effect that the closing slide 3 is lowered by means of the links 29 in the open and / or closed position compared to a position outside of said open or closed position.
• the switching, raised intermediate position results from FIG. 10.
• the sliding block projections 30 pass through the head side of the sections of the trapezoidal connecting link 29.
• the function is, briefly summarized, as follows: By moving the slide valve 3 in the direction of the edge 4 ', the valve membrane 17 is moved to the passage 10 in a congruent position. The exit route is free.
• the dispenser designed as a standing device, is transferred to a falling position. By exerting pressure on the dispensing container 1, substance identified by the dashed structure emerges.
• the closure membrane 18 previously sealing the passage 10 has been moved into a parking position, that is to say it has been fed to the trough 27.
• a configuration can also be made such that a closure membrane 18 is held in the closure slide 3 and can be displaced with it between the closed position and the open position.
• the valve membrane 17 is then firmly arranged in the area of the passage 10 in the bottom 8 of the cap 4.
