Definitions
- the invention relates to a closure device for containers with flowable media, in particular for cleaning agents, cosmetics or the like, consisting of a housing which can be fastened in a media-tight manner with a container opening and has an outlet connection which is connected to an outlet opening which releases the medium, a closure element, by means of which the outlet connection can be closed and released in a media-tight manner, and an actuating element, by means of which the closure element can be moved into its desired positions.
- a generic closure device in which the actuating element is designed as a tilting cover.
- a closure element designed as a sealing ring is arranged on the underside of the tilting cover and engages sealingly in the outlet opening of the outlet nozzle.
- a sealing cap is arranged on the underside of the tilting cover, which in the closed position and in the open position sealingly surrounds the outlet connection on the outside.
- closure devices are therefore desired which optionally release at least two different opening cross sections, so that the opening cross section can be adapted to the medium in question or its dosage.
- the releasable opening cross-section should be as large as possible Range can be varied so that the closure device can be used as universally as possible.
- the closure device described in EP 0 411 311 A1 it proves disadvantageous here that the closure element can only be moved into an open and a closed position, so that different opening cross sections cannot be released depending on the viscosity of the media.
- the opening cross section is limited to a comparatively small size due to the limited pivoting range of the closure element, since otherwise a sealing contact of the sealing cap on the outlet nozzle cannot be guaranteed.
- the present invention is therefore based on the object of providing a closure device in which different opening cross sections can be released over a wide range, and which can be produced simply and inexpensively.
- the closure element is designed so that the medium can flow through it, one end region of which has an inlet opening that can be received in a media-tight manner from a seat, and another end region is connected to the outlet opening that clears the medium, in that the closure element and sealing seat are relative are spaced from one another and, depending on the spacing, the inlet opening of the closure element can be opened in at least two different opening cross-sections, and that the component moved when the closure element and sealing seat are spaced is guided in a media-tight guide over its entire travel path.
- the spacing of the closure element through which media can flow Due to the extent of the spacing of the closure element through which media can flow, relative to the sealing seat, different opening cross sections of the inlet opening can be released. Since the component traversed during the spacing is guided in a media-tight guide over its entire traversing path, the spacing can be dimensioned such that, in the end position of the traversing path, the part that is released from the inlet opening A cross section corresponds to the cross section of the closure element through which media can flow. This creates a maximum opening cross-section so that even highly viscous media can easily pass through the closure device.
- the closure element can be adjusted continuously or stepwise to different target positions, as long as it is ensured that a media-tight guidance is ensured when the component is adjusted in height.
- the travel path can be linear or along a circular arc, so that the actuating element can be designed as a thrust element or as a tilt or twist lock.
- the spacing of the closure element and sealing seat, the closure element or the sealing seat or both can be moved by means of the actuating element.
- the closure element can be designed as a vertically arranged, height-adjustable tube.
- the media-tight guide can be designed as a cylinder that completely surrounds the tube or can only extend over a partial area of the circumference.
- the tubular closure element is designed to be open on its lower end face and can be applied sealingly to the sealing seat. As a result, the entire inner cross section of the tube can be released with appropriate spacing, for example by means of a vertical stroke.
- the sealing seat can be arranged in a stationary manner on the housing, for example by being integrally formed thereon. If the closure element is designed as a tube, its upper end face can be provided with an opening which is connected to the outlet opening of the closure device via an outlet channel. The outlet channel can - starting from the end face - also extend over a partial area of the lateral tube wall.
- a structurally particularly simple embodiment is present when the closure element is integrally formed on the actuating element with the end facing the outlet opening.
- the outlet channel is arranged in the actuating element and emerges laterally therefrom, the actuating element in the closed position of the closure element in the region of the outlet channel sealingly abutting the inner wall of the housing and the outlet opening completely in the first of the open positions releases.
- the outlet channel is completely exposed in each opening position and can be flushed completely through the emerging medium, so that no incrustations of the medium can become lodged in the outlet channel.
- the closure element and the guide surrounding the closure element in a media-tight manner can be shaped like an arc, so that there is a tube-in-tube guide.
- a structurally particularly simple embodiment is, however, present in the case of an actuating element designed as a rocker arm if the closure element is connected to the rocker arm eccentrically to the pivot axis and is designed as a flexible tube. If, for example, a cylindrical guide sleeve is provided, the rocker arm arranged in the guide sleeve is lifted by pivoting the rocker arm. Neten flexible tube and the region of the flexible tube protruding from the cylindrical guide sleeve is deformed in an arcuate manner. As a result, the comparatively complex formation of arc-shaped components which move relative to one another and which abut one another in a sealing manner is unnecessary and a particularly simple, very well-sealing tube-in-tube guide is created.
- the locking element is designed as a flexible tube, which is deformed in an arc when a rocker arm is actuated, then elastic restoring forces act on the rocker arm located in an open position due to the elastic deformation of the locking element. It is then particularly advantageous to provide a detent with different detent positions which engages the rocker arm and locks it in its different open positions. Such a detent is advantageous for simple adjustment of the dosage if the actuating element is designed as a slide.
- rocker arm is supported by means of pins
- circular segments formed on the rocker arm below the pins can be provided, which are supported in front of and behind the axis of rotation by supports and prevent inadvertent axial movement of the rocker arm while exerting a vertically downward pressure.
- the circle segments can be provided with undercuts into which a locking cam can be inserted in a latching manner.
- the latching connection is thus arranged in each of the opening positions of the rocker arm within the locking device and is protected, for example, from contamination.
- the latching cam can be arranged on a leaf spring arranged between the supports or can itself be designed as a spring element.
- FIG. 1 shows a section through a closure device according to the invention in the closed state
- FIG. 2 shows the closure device according to FIG. 1 in a first opened state
- FIG. 3 shows the closure device according to FIG. 1 in a further opened state
- Fig. 4 is a plan view of the closure device of Figure 1 without a rocker arm.
- Fig. 5 shows a section through the closure device of FIG. 4 along the line V-V.
- the closure device according to the invention shown in FIGS. 1 to 5 is designed as a tilt lock.
- the closure device 1 has a cup-shaped housing 2 which is arranged coaxially with the outlet connection 3 of the container and is screwed to the latter by means of the threaded connection 4.
- the housing 2 has a cylindrical outlet connection 5, which is arranged coaxially in the housing 2 and is provided with a lateral opening 6.
- a sealing lip 7 is arranged concentrically between the outlet connector 5 and the threaded connector 4, which sealingly rests on the outlet connector 3 of the container.
- the lateral opening 6 of the outlet nozzle 5 can be closed in a media-tight manner by the vertically arranged tube section 8, which acts as a closure element, and can be opened in various opening positions.
- the cylindrical tube section 8 is sealingly guided in a longitudinally displaceable manner in a guide sleeve 9 over its entire circumference and is integrally formed at its upper end on the rocker arm 10 pivotally mounted about the horizontally arranged central axis of the viewing housing 2.
- the lower, frontally open end of the closure tube 8 can be arranged in a media-tight manner in a sealing seat 11, the middle one Area is supported by the threaded connector 4 and which is integrally formed on the housing 2. This results in a particularly stable and space-saving arrangement of the sealing seat 11.
- the upper end of the closure tube 8 merges into an outlet channel 12 which is angled at right angles to this and which is arranged in the rocker arm 10 and can be pivoted therewith.
- the outlet channel has a smaller cross section than the sealing tube, so that a flow-technically favorable embodiment is given.
- the outlet opening 13 which releases the medium is arranged behind a partial region of the housing 2, the outlet-side end of the outlet channel 12 sealingly abutting the inner wall of the partial region of the housing 2.
- the lower end of the tube 8 which is open at the end lies sealingly against the sealing seat 11. This provides a double seal for the closure device, so that a secure storage of the medium in the container is ensured.
- the closure device If the closure device is moved from the closure position shown in FIG. 1 into a first opening position, as illustrated by way of example in FIG. 2, by actuating the rocker arm 10, the lower end face of the tubular closure element 8 is spaced from the sealing seat 11 and the outlet channel 12 is pivoted upward with its end facing the inner wall of the housing 2, and so the outlet opening 13 arranged on the end side of the outlet channel 12 is arranged completely above the edge of the housing.
- the region of the elastic closure element 8 arranged above the guide sleeve 9 is deformed in an arc shape.
- the pivoting movement of the rocker arm can be converted into a lifting movement of the closure tube 8, with the tube 8 and the latter being sealed at the same time.
- the sealing seat 10 can be made planar, while the area of the inner wall of the housing 2 that seals the outlet opening 13 and the area of the outlet channel 12 in contact with it Spherical spheres are shaped. Due to the planar design of the sealing seat 11, it can be produced with particular dimensions.
- FIG. 3 shows the locking device in a further opening position, in which the rocker arm 10 is pivoted further out of its locking position and the lower end of the locking element 8 is further apart from the sealing seat 11.
- This opens up a larger cross-sectional area of the opening 6 arranged laterally on the outlet connection 5.
- a medium of higher viscosity can easily pass through the closure element 8 and ultimately through the outlet opening 13.
- the closure device can thus be transferred into different opening positions, in which media with clearly different viscosities can be removed from the container with precise doses.
- the cross section of the opening 6 can be dimensioned such that it coincides with the flow through the cross section of the closure element 9, the closure element 9 completely opening the opening 6 with the greatest stroke.
- the closure element 8 consists of the same material as the rocker arm 10 and is integrally formed thereon.
- the flexibility of the closure element 8 is achieved by a suitable dimensioning of the same wall thickness.
- the closure element 8 can also be made of a different material than the rocker arm 10 and can be attached to it, for example, by gluing or be held by a press fit.
- the actuating element can also be designed as a thrust element displaceable axially relative to the housing 2.
- the closure element 8 could also be formed as a rigid tube and the end of the outlet channel 12 facing the outlet opening 13 and the region of the housing wall sealingly adjoining it could be formed as cylindrical outer surfaces.
- both the housing 2 and the outlet connection 5 of the closure device each have a circular cross section.
- the closure element 8 and the guide sleeve 9 surrounding it sealingly also have a circular cross-section, the closure tube 8 being arranged on the circumference of the outlet connector 5, the longitudinal axis of the closure tube 8 being arranged radially outwardly offset to the circumference of the outlet connector 5 is and the sealing tube 8 overlaps in a partial area with the connecting piece 5. This ensures exact guidance in the sealing area of the tube 8, since the guide sleeve 9 encompasses the closure element 8 by more than half its circumference.
- rocker arm 10 is pivotally mounted by means of the pin 14, the pivot axis running in the central plane of the locking device.
- flat circular segments 15 are integrally formed on the rocker arm 10, which serve to hold the rocker arm 10 under the action of a vertically downward pressure.
- the circular segments 15 in front of and behind the axis of rotation of the rocker arm 10 are supported by supports 16 which are formed in one piece in a bar-shaped manner on the inner wall of the housing 2.
- the supports 16 point an arc-shaped support surface corresponding to the circular segments 15.
- a plurality of undercuts 17 are arranged at a distance from one another on the circumferential surface of the circular segments 15.
- a leaf spring 18 is provided, at the apex of which a detent cam 19 is integrally formed, which can be inserted into one of the undercuts 17 by pivoting the rocker arm 10.
- each of the desired positions into which the locking device can be transferred is assigned a defined pivoting position of the rocker arm and a corresponding arrangement of the locking cam 19 in one of the undercuts 17.
- the arrangement of the detent cam 19 on the leaf spring 18 means that the detent lock can be actuated easily in both tilting directions of the tilting lever and, since it is arranged on the inner wall of the housing 2, is protected against external interference.
- the actuating element of the closure device is designed as a push element
- the actuating element can also be equipped with guide grooves and the housing with corresponding guide webs, the push element having a laterally arranged recessed grip and undercuts arranged on its circumference, which also have on the Corresponding locking cams arranged on the inner wall of the housing 2 can optionally be brought into engagement. With axial displacement, the actuating element can then be converted into different latching positions, each of which releases a different stroke of the closure element 8 and thus correspondingly a different area of the cross section of the opening 6.
- closure device can also be designed as a rotary closure, the actuating element arranged concentrically with respect to the housing 2 being rotated relative to the latter along its longitudinal axis and thus the closure element 8 being spaced from a correspondingly shaped sealing seat.
