Closure device for a container field of technology

The invention relates first to a closure device for a container having a container opening, wherein the closure device comprises a lid member for closing the container opening, a lid member associated with the chamber and an inner housing, further comprising the chamber and the inner housing mutually corresponding closure means and opening means which interact with one another such that a discharge opening associated with the chamber as opening means can be released relative to the inner housing by a rotating movement of the closure element connected to the cover element, so that a medium stored in the chamber can escape into the container.

State of the art

Closure devices of the aforementioned type are known in the art. These serve to close off a container and at the same time to provide a chamber for the separate storage of liquid or powdery media, for example tea essences or the like, so that it does not react immediately upon filling the container with the contents of the container, i. For example, water, come into contact and / or mixed, but only at the moment in which the closure device is removed from the container. This is usually the moment in which the content of the container is to be consumed.

The document WO 2007/129116 AI, for example, relates to a closure device of the aforementioned type which emits an additional liquid located in the chamber in the container when opening a sealed container. The closure device has a cover element, a Chamber and an inner housing. The inner housing has a discharge opening into which a plug element connected to the inner housing sealingly engages. The cover element and the inner housing are connected to one another by screw threads, wherein the cover element can be raised relative to the inner housing from a closed position in which the plug element closes the discharge opening of the chamber into a discharge position in which the plug element is at least partially withdrawn from the discharge opening is to provide a communication path from the chamber into the main liquid space of the container. In this case, the medium stored in the chamber can exit into the container, where it is mixed with the medium in the container.

Summary of the invention

Based on the stated prior art, the invention is concerned with the task of specifying a closure device, which allows for effective producibility effective emptying of the chamber in the course of removal of the cover element.

According to a first solution, the invention proposes for this purpose that the closure means is a closure pin fixedly connected to the chamber, which has a vertical extent given in the direction of rotation and that the closure means has different areas over the vertical extent, a passage area and a closure area, is formed.

The closure means is preferably a closure pin. The closure region can in this case be formed as a cylindrical part with an outer diameter which corresponds to the inner diameter of the opening means, such as the discharge opening, or slightly exceeds this. The latter is particularly useful and possible if the opening means in this area consists of an elastic, flexible material, in particular a thermoplastic elastomer. In contrast, the passage region may be a region which is tapered over the entire circumference or only part of the circumference of the closure means. If the tapered region protrudes upwards out of the opening means by corresponding rotation of the cover element, a free space is created through which mass contained in the chamber, in particular a liquid, can flow out of the discharge opening. In this case, the passage region may also extend completely or partially within the opening means.

This object is further achieved in a closure device, in which is geared to that the closure means is a closure pin and that the closure pin is connected to the chamber by means of a locking part. The formation of the closure means as a verraste- with the chamber locking pin allows a materially different training to the formation of the chamber. The chamber can also initially be formed open on the side of the closure means and thus be better able to be produced, for example, in the plastic injection process. The latching of the closure means with the chamber can also be used at the same time to seal in Verrastungs- area.

Alternatively, the closure means may be formed, in particular with regard to the indicated first solution, as well as firmly connected to the chamber closure pin.

The discharge opening can optionally also be referred to as a closure opening.

The closure means, in particular the closure pin, is arranged on the chamber, while the opening means, ie in particular the closure opening or discharge opening, is preferably formed on the inner housing. In a closed position of the closure device, the closure plug closes the closure opening by placing it either in the shutter opening engages or covers it. By opening the closure device, ie a spacing of the lid member from the container - and thus simultaneously displacement of the chamber relative to the inner housing - the closure pin is removed from the closure opening, so that the medium contained in the chamber can flow through the closure opening into the container , In the manufacture of the closure device, the chamber is advantageously introduced concentrically into the inner housing, wherein the closure pin is displaced simultaneously into a position closing the closure opening. Since the plug is firmly connected to the chamber, it retains its relative position and orientation to the chamber even during assembly of the plug so that it automatically comes into contact with the plug through the position and orientation of the chamber.

According to a further solution of the invention it is provided that the cover member is relatively movable relative to the chamber in a removal direction of the lid member in a first movement portion of the lid member in the course of removing the cover member of the container relative to the container and in a second Motion section with the container is motion coupled. In this way, a certain lift of the cover element can be achieved without the container is moved.

The cover element is in particular in the first movement portion rotatable relative to the chamber.

Further, it is also preferably provided that the cover element in the first movement section is movable vertically to the chamber. Thus, while the lid member is raised, for example by a unscrewing movement, the chamber remains in its originally assumed position with respect to a vertical. According to a further solution, it is provided that the opening means have an opening relative to the movable chamber opening part, which forms two circumferential sealing zones, which are concentric in a direction perpendicular to a given upon opening movement direction of the opening means relative to the chamber are arranged to each other.

The opening means may cooperate with the chamber at the two concentrically formed sealing zones. In this case, there may be an interaction with a closure pin firmly connected to the chamber and a further interaction with a receiving opening surrounding the closure pin on the chamber for the opening means.

Preferably, a medium that can be dispensed from the chamber, under pressure. For this purpose, a corresponding compressed gas region above a liquid level, when the medium is liquid, may be provided during the filling.

In particular, in such under pressure medium, the safe, but also production technology low controllable seal is essential. Characterized in that two concentric sealing zones are formed, suitably two circumferential, more preferably cylindrical regions can be sealingly detected. In particular, it may be a cylindrical inner surface and a cylindrical outer surface of corresponding regions of the chamber which are sealed by the opening means. The invention also relates to a closure device for closing a container opening of a container, in particular a beverage bottle, wherein the closure device has a cover element, one on the cover element. ment arranged chamber and an inner housing, wherein the chamber and the inner housing mutually corresponding closure means and opening means which interact with each other so that a medium contained in the chamber can escape due to a movement of the lid member relative to the inner housing in the container.

In order to further improve a closure device of the type in question, it is provided according to a further solution that the closure means is a closure pin connected to the chamber by means of a detent part, which is formed by movement of the cover element relative to the inner housing a closure opening forming the opening means of the inner housing is removable.

The closure pin is separately produced in this possible embodiment to the chamber, according to the present invention can be present in the course of assembly of the closure device initially as a lot part. This offers advantages in terms of production, and in particular with regard to the choice of material. The closure pin can thus in the simplest way from a different material, in particular plastic material, consist, as the lock pin ultimately haltering chamber.

Preferably, the closure pin is locked to the chamber, for example. Using a detent member or latching portion provided therefor.

In addition, a welding, possibly also an adhesive connection is possible for holding the closure pin to the chamber.

In addition, the invention relates to a closure device for a container, having a container opening, wherein the closure device comprises a lid member for closing the container opening, arranged on the lid member chamber and an inner housing, wherein the chamber and the inner housing to each other corresponding closure means and Having opening means which interact with each other, in that a discharge opening assigned in the chamber can be released by a movement of the cover element relative to the inner housing, so that a medium stored in the chamber can exit into the container, wherein furthermore the cover element has a thread for unscrewing the closure device from the container ,

Such closure devices are known from the cited prior art.

In order to provide an alternative closure device, the invention proposes in a possible solution to the problem that the inner housing has a first Ausgabeausformung that when unscrewing by a single relative rotation between the chamber and the inner housing in a matching alignment with a formed on the chamber second Ausgabeausformung comes.

[0027] According to the invention, the medium stored in the chamber can only be discharged into the container through the discharge opening if the output formations of the inner housing and chamber are brought into a coincident position. This can be achieved only by turning the cover element relative to the inner housing. As a result of this rotation, one of the output formations is brought into the corresponding position with respect to the further output formation. Also, the rotational movement may be superimposed by an axially directed sliding movement.

Preferably, the movement, in particular the rotation of the cover element stop limited.

Only by the displacement of the one output shaping in the coincident orientation to the other Ausgabeausformung an exit path between the chamber and the discharge opening is formed. The closure device acts in a possible embodiment functionally equal to a rotary valve valve.

According to another solution thought is provided in this context that the chamber has a (second) output molding, which opens an output path by an axial relative displacement between the chamber and the inner housing.

The closure device acts here functionally similar to a slide valve. The output formation of the chamber is displaced axially by the relative displacement of the lid member to the inner housing, in particular by a rotational displacement of the lid member into a position which releases a flow path from the chamber into the container interior.

The Ausgabeausformungen may be given by channels in the relevant components, alternatively by groove-like depressions in the region of the interacting surfaces of inner housing and chamber. In a further embodiment, a chamber-side (second) output molding in the region of the chamber-side closure means may be formed and possibly corresponding thereto in the region of the inner housing-side opening means a (first) Ausgabeausformung.

It can be provided that the closure pin is formed integrally with the chamber. In particular, it is advisable to produce the chamber including the closure pin by means of a plastic injection molding process, so that no separate manufacturing step for connecting the closure pin to the chamber is required. Since the chamber is regularly made of a plastic, for example polybutylene terephthalate (PBT) or polypropylene (PP) or polyethylene (PE), an injection molding process is suitable. Due to the one-piece design of the closure pin on the chamber, the position and orientation of the closure pin remains relative to the chamber constant, so that the closure pin when connecting the chamber with the inner housing reliably passes into a position closing the closure opening. In principle, however, it is also possible in addition to the one-piece design to arrange the closure pin in a different manner to the chamber. For example, the plug may be glued or welded to the chamber. Also, the closure pin or a portion carrying this can be entangled with the chamber, so that there is a non-detachable latching connection. It is essential to produce a firm connection between the chamber and the closure pin, so that the closure pin can not be separated from the chamber during use in the closure device.

Furthermore, it is proposed that the closure pin has a cantilevered closure end which can be inserted into the closure opening. For example, the closure pin may be arranged on the chamber wall in the manner of an L-shaped web, so that the free closure end points in the direction of the closure opening of the inner housing. In the case that the chamber is cylindrical, the end portion of the closure pin carrying the closure end is arranged on the longitudinal axis of the chamber. In principle, different embodiments of the locking pin are conceivable. For example, a plurality of radially arranged webs may extend radially from the inner wall of the chamber to the longitudinal axis, wherein the webs carry the end portion having the closure end in a star shape. Advantageously, the closure pin is arranged in a partial region of the chamber, which is tapered in the manner of an outlet region with respect to the remaining region of the chamber, so that the chamber has a smaller diameter in the region of the closure pin.

In addition, the closure end advantageously has a diameter which substantially corresponds to the inner diameter of the closure opening. In this case, the outer diameter of the closure end and the inner diameter of the closure opening are designed so that the Closure end is inserted into the closure opening, optionally with intermediate storage of a sealing element. The closure end is thus inserted into the closure opening in the manner of a stopper. In the alternative case that the closure end is not inserted into the closure opening, but rather closes the closure opening from the outside, a correspondingly larger diameter of the closure end than that of the closure opening is recommended.

It is proposed that the closure opening and / or the closure pin is associated with a sealing element for fluid-tight closure of the closure opening with the closure pin. Both in the case that the closure end of the closure pin is arranged in front of the closure opening, as well as in the case that the closure end protrudes into the closure opening or through this and optionally exits the bottom opening from the closure opening, a sealing element for fluid-tight connection of Closure end or closure pin and closure opening. The sealing element may advantageously be a sealing rubber or the like. This sealing element can be arranged either on an edge region of the inner housing delimiting the closure opening, on the closure end of the closure pin or both on the closure opening and on the closure pin.

Advantageously, the inner wall of the closure opening is associated with a sealing element, wherein the inner wall is coated in particular with the sealing material. It is provided to introduce the closure end of the closure pin with intermediate storage of the sealing element / the coating in the closure opening. By the inside coating of the closure opening with a sealing material, a sealing element can be formed, which always maintains its position at the closure opening and thus contributes to an optimal sealing of the closure opening. Furthermore, it is proposed that the closure opening is part of a flow channel whose length corresponds to at least five times its diameter and a maximum of twenty times its diameter. The medium flowing out of the chamber must therefore flow through the flow channel in order to reach the container. Thus, it is achieved that the medium is not bubbled out of the chamber, but rather over a certain period of time and with a relatively fine jet. This promotes not least the better miscibility of the existing medium in the container with the effluent from the chamber medium. The closure end of the closure pin need not be introduced over the entire length of the flow channel in this, but may for example be introduced into the flow channel only in the region of the closure opening, for example with a length of a few millimeters.

This facilitates the joining of the chamber to the inner housing since the closure end or the closure pin does not have to be introduced into the flow channel over a greater length, in particular not over the entire longitudinal extension of the closure pin and / or the flow channel.

It can also be provided that the chamber has a container-side opening and that the latching part surrounds an opening edge of the opening with a cross-sectionally U-shaped design. The opening edge of the opening is preferably designed for the latching holder of the locking part having the locking part. The locking determination is operationally not reversible.

In addition, the (second) output formation of the chamber can also form an inferior region of the discharge path in an opening state of the closure. Thus, in the open position of the closure with its free end facing away from the chamber, furthermore, the closure means optionally having closure means may preferably freely, ie not directly encompassed by sections of the inner housing, dive into the interior of the container. In a further embodiment, the dispensing opening on the inner housing can form a sealing lip abutting the closing means of the chamber. This sealing lip is preferably provided circumferentially in a circular cylindrical design of the closure means and preferably cooperates both in the closed position and in the open state of the closure with the facing outer surface of the closure means.

When the closure is opened, the medium preferably exits under pressure. The voltage applied to the closure means sealing lip is raised by the exiting medium in an open position. After emptying the chamber and correspondingly decreasing pressure on the sealing lip, the latter, according to the given elastic resilience, restores it to the outer surface of the closure means. An uncontrolled leakage of residual media amounts (dripping) is counteracted by the arrangement and effect of the sealing lip. In a further embodiment, the chamber may have a chamber bottom, wherein the chamber bottom may pass into a channel having a discharge opening. In the case of such an embodiment, the channel bottom is preferably distanced in the axial direction to a region of the chamber bottom. This may result in a gradient between the bottom of the chamber and the channel, in particular the channel bottom, which in one possible configuration may be formed solely by the channel wall delimiting the channel bottom in the transition to the chamber bottom.

The channel may be formed closed like a ring, in particular ring-like with respect to a rotation axis. If necessary, the channel completely surrounds the chamber bottom, possibly bordering it radially outwards at the same time.

The discharge opening may be formed in a channel bottom and / or in a channel side wall. In the case of the arrangement or design of the discharge opening in the channel bottom results in a preferred embodiment a lowest possible arrangement of the discharge opening. An axis that passes centrally through the discharge opening can in this case extend substantially perpendicular to the chamber bottom or to a bottom plane oriented transversely to the axis of rotation. In the case of the arrangement or design of the discharge opening in the region of the gutter side wall, a discharge flow of the medium directed radially outward from the gutter results from the chamber. Such a discharge opening is also preferably formed within the axial height extent of the channel, if necessary at least tangent to the channel bottom.

In addition, the discharge opening can also be formed both in the channel bottom and in the channel side wall, possibly by providing both a discharge opening in the channel bottom and a discharge opening in the channel side wall. In addition, only with respect to a cross-section can a drain opening be provided in a transition region from channel bottom into the channel side wall.

Also, over the circumference of the channel a plurality of discharge openings may be formed, either alone in the region of the gutter bottom or alone in the region of the gutter side wall, but also optionally alternately in the region of the gutter bottom and the gutter side wall.

In particular, for sealing cooperation with the closure means, the chamber bottom may have a soft plastic layer in a possible embodiment. Particularly in the closed position, the closure means preferably interacts with the soft plastic layer. The soft plastic layer extends in a further possible, as well as preferred embodiment into the region of the channel, in this case in particular enclosing the region of the outlet opening. Thus, furthermore, the soft plastic layer can extend over the channel bottom and / or the channel side wall.

The discharge opening may be formed in this case, if necessary, alone in the soft plastic layer. Accordingly, the soft plastic layer extends into the region of the discharge opening, preferably completely forming the wall of the discharge opening.

The closure means may dive in the release opening in the manner of a peg in order to seal it in a sealed manner. In an alternative embodiment, the closure means acts like a slide. To produce the soft plastic layer, for example, a thermoplastic elastomer can be used.

Description of the embodiments

Shown and described is a closure device 1 with a chamber 6, which has a lower opening, relative to which opening means, which allow emptying of the chamber 6 are provided. The opening means consist concretely of an opening part, which is given in a further concretization in the embodiment by a sealing element 10. This opening part has two circumferential sealing zones, namely once a sealing zone, which is preferably formed on an outer peripheral surface of the opening means, which cooperates with an inner surface of the chamber 6 and further a sealing zone, the opposite to the inwardly offset offset. is formed and in the embodiment with a, a closure means V forming closure pin 7 cooperates. Said sealing zones are arranged in a direction perpendicular to one another, relative to the chamber 6, relative to a movement direction R of the opening means given on opening.

2 shows in a first embodiment, an upper portion of a container 2, here a beverage bottle, at the container opening 3, a closure device 1 is arranged. The closure device 1 is located relative to the container 2 in a position which closes the container opening 3 in a fluid-tight manner. The closure device 1 is screwed in the usual way to the container 2, so that the container opening 3 is closed. In this state, the container 2 can be stored for a long time without the contents of the container 2 can escape. To open the container 2, the closure device 1 is unscrewed in a conventional manner from the container 2, so that the container opening 3 finally completely exposed.

The closure device 1 comprises a cover element 4, a chamber 6 arranged on the cover element 4, and an inner housing 5. In the embodiment shown - not limiting - the cover element 4 is a plastic cover, for example made of polypropylene (PP) or polyethylene (PE).

Figures 1 to 5 show an embodiment of the closure device 1, wherein the chamber 6 is made as a separate part, for example. In plastic injection molding. Also, for the production of the chamber, a plastic injection-blow molding Ver stretch Verfhren be used, in which for the production of hollow bodies of a thermoplastic material in addition to the usual injection-blow molding (extrusion blow molding) before or simultaneously with the blow molding an extension of the heated preform is made in the longitudinal direction, for example, using a guided through the preform muzzle stretching rod. An achievable inflation Rate (smallest mouth diameter: to the largest outer diameter), for example, can be up to 1:10.

The chamber 6 thus produced is finally entangled with the cover element 4, according to this rastgehaltert. For this purpose, as also shown, the outer wall of the chamber 6, a circumferential collar 19 may be provided for latching cooperation with a corresponding latching projection 20 of the cover element. 4

Flats 21 can be provided over the circumference of the chamber wall and in the corresponding areas of the cover element wall, for example, to transmit the screw torque when the cover element 4 is screwed in. The chamber 6 is held against rotation on the cover element 4. FIG. 2 shows, by way of example, a longitudinal section through the flattening regions of the closure device 1. This longitudinal section in FIG. 2 is offset from the further longitudinal sections according to FIGS. 1 and 4 by approximately 90 ° about the longitudinal axis.

The result is a one-part of the chamber 6 with respect to the circumferential chamber wall and the chamber ceiling, as well as the adjoining the chamber wall in the longitudinal extension drain port 13 with a container-side opening. At the chamber 6, in particular at the discharge nozzle 13, the closure means V or the closure pin 7 is latched in this embodiment. The latter is viewed in longitudinal section substantially UF örmig formed, with a circumferential, the free end of the drain neck 13 comprehensive locking collar 23. This engages in the Rastfestlegungsstellung a correspondingly adapted radial stage of the drain port 13 along the opening edge. The latching part 22 forms an inner circumferential wall, which is supported on the outlet connection 13 on the inside of the wall. On this wall, the locking pin 7 is formed, for example via a Kreuzsteg- arrangement.

The inner housing 5 has a pot-like shape with a circumferential pot wall and a collar for support on the container rim surrounding the container opening 3.

On the underside of the inner casing collar circumferentially a sealing lip 24 is integrally formed. This acts in the assignment position with the container opening 3 surrounding the container wall. This pylon-shaped, the flow channel 11 having formation can, as not shown in detail, connected via a cross-web-like connection with the channel dome 14, the pot-side be. In particular, the above-described connection region is overmolded in the illustrated embodiment of the material of the sealing element 10, so that the sealing element 10 extends substantially facing the chamber 6, but also at least partially below the cathedral ceiling. The sealing element 10 can, as shown, for example, in FIG. 1, face the chamber 6 in a funnel-shaped manner, tapering in cross-section from radially outward toward the center.

The outer diameter of the sealing element 10 corresponds to that of the channel dome 14 and, moreover, is adapted to the free inner diameter of the locking part 22 carrying the locking pin 7, so that in the position of use a sealing effect between the sealing element 10 and the inner wall of the chamber 6 and the latching part 22 is reached.

Furthermore, the locking part 22 can also be held by a weld on the chamber 6. The inner housing 5 is also connected here via a thread 15 with the chamber wall.

In the closure position according to FIG. 2, the closure pin 7 dips into the closure opening or discharge opening 8 for the sealing closure of the chamber 6. The lid element 4 and the chamber 6 move axially relative to the closure pin 7 Inner housing 5 is reached, wherein the closure pin 7, the closure opening 8 for dispensing the stored medium from the chamber 6 releases into the container interior. The inner housing 5 is (initially) secured against rotation via a frictional engagement between the sealing lip 24 and the container wall.

A further embodiment is shown in FIGS 6 to 9. Here, the chamber 6, in particular the circumferential chamber wall and the chamber ceiling is preferably provided as an insert, which is encapsulated to form the cover element 4. The substantially the discharge nozzle 13 ausformende and in this Embodiment one-piece, the closure pin 7 forming portion of the chamber 6 may, as also preferably, be made separately and ultimately connected to the insert to form the chamber 6 according to preferred welding. The drain neck 13 has a funnel-shaped tapered portion, which merges into a end side of the closure pin 7 bearing cylinder portion 25. The locking pin 7 is also here preferably via a Kreuzsteganordnung on the cylinder portion 25 is supported, wherein the locking pin 7 in the axial extension direction over the free end of the cylinder portion 25 protrudes.

The inner-housing-side sealing element 10 is pot-shaped, with a peripheral sealing wall, the outer side of the wall abuts the cylinder portion of the drain port 13. In the sealing pot bottom, the closure opening 8 is formed. The flow channel 11 is essentially formed by the sealing element 10.

The pot-shaped sealing element 10 is circumferentially outer wall and underside of the sealing pot bottom covered by a corresponding cup-shaped portion of the inner housing 5. It follows in the closed position shown in Figures 6 and 7, a seal substantially in two concentric areas. So on the one hand in the region between the cylindrical wall of the drain port 13 and the peripheral sealing pot wall and further in the region of the flow channel 11, in which the relevant circumferential wall of the sealing element 10 abuts against the corresponding outer wall of the closure pin 7.

The closure pin 7 has a (second) output formation 26. This is formed by a longitudinal groove which opens to the circumferential wall surface of the closure pin 7 and the free end of the same. In the closed position, the closure pin 7 is seated completely in the flow channel 11 in the illustrated embodiment. In this case, the dispensing formation 26 extends over an axial length which is less than the axial length of the sealing region between the closure pin 7 and the sealing element 10. Thus, the dispensing formation 26 extends, for example, over half the axial length of the closure pin 7.

Shown is only a Ausgabeausformung 26 in the form of a groove. It is also possible to arrange a plurality of distributed over the circumference formed grooves or the like. Furthermore, a circumferential radial constriction for forming the output molding 26 is possible.

By the axial displacement of the chamber 6 relative to the inner housing 5, the closure pin 7 is raised in a position shown in Figure 9, in which the sealingly cooperating with the sealing element 10, not affected cross-section area of the closure pin 7 leaves the flow channel 11 and the Output molding 26 is placed in a position in which it releases a flow path between the chamber interior and the flow channel 11. The output molding 26 is raised beyond the plane of the dispensing opening. It is sufficient, as shown in Figure 9, that the closure pin 7 is not completely lifted from the sealing element 10, although, as shown in Figure 10, such a solution is possible.

In addition, with corresponding axial extension of the closure pin 7 downwards beyond the inner housing 5, this discharge molding 26 can also form a lowermost region of the discharge path in the outlet state according to FIG. 9 (see dot-dashed representation in FIG. 9). Shutter pin 7 and inner housing 5 or sealing element 10 act in this embodiment in the manner of a slide valve.

Figures 11 to 14 show an embodiment in which the closure pin 7 and the sealing element 10 cooperate in the manner of a rotary valve.

Based on the essential arrangement and design of the closure device 1 according to the embodiment described above, here the inner housing 5 is not connected via a thread with the chamber 6, but rather via a latching connection, a relative rotation of the chamber 6 to the inner housing 5, preferred over a predetermined angular range, allows.

The closure pin 7 is permanently seated in the sealing element 10 in this embodiment, is accordingly not displaced axially relative to this. There is only a displacement of the closure pin 7 relative to the sealing element 10 in the circumferential direction, this preferably stop limited over an angle of about 180 °.

As in the previously described exemplary embodiment, the closure pin 7 also has a (second) dispensing formation 26 in the form of a groove extending on the side of the wall in the axial direction. This is in the closed position according to Figures 11 and 12 with respect to a cross section perpendicular to the axis extension offset by about 180 ° to a nengehäuseseitigen first Ausgabeausformung 27. This first Ausgabeausformung 27 is preferably formed in the form of a groove, in particular in shape a running in axis extension groove, which is arranged on the wall side of the flow channel formed by the sealing element 11 11. The output molding 27 extends from the closure opening 8 and the to the chamber 6 directed towards the opening plane about half the length of the flow channel eleventh

Accordingly, a circumferentially partial radial expansion of the channel cross-section results in this area. As a result of rotational displacement, the closure pin 7 in the sealing element 10 is inserted in a locking manner into the outlet position, in which, as shown in FIG. 14, the dispensing formations 26 and 27 are brought into a matching orientation. A superimposition of the groove-like output formations results in the axial direction, so that they form the flow path for dispensing the medium located in the chamber 6.

In this embodiment, the inner housing 5 is already raised axially relative to the container opening 3 via the first rotational travel of approximately 180 ° in order to achieve the outlet position. The sealing lip 24 has a sufficient axial length in order to be able to apply a sufficiently high holding torque in spite of this axial displacement in the course of the rotational displacement from the closed position into the outlet position, to prevent rotation of the inner housing 5.

In the region of the dispensing opening 28, a circumferential sealing lip 29 is provided on the inner housing 5 or formed directly from the sealing element 10. This acts against the peripheral surface of the associated region of the closure pin 7, both in the closed position and in the outlet position. In this way, in particular in the outlet position of the closure device 1, which also corresponds to the removed lid position, a seal of the flow channel 11 is provided. A lid removed from the chamber 6 into the container 2 after the medium has been dispensed and deposited on a storage surface can thus not lose any remaining quantity of medium from the chamber 6. Pollution of the work surface or the environment is counteracted. Since in the outlet position after delivery of the medium, no increased pressure in the chamber 6 compared to the environment is present, such a lip-shaped seal against dripping of possible residual amounts is sufficient. The closure device 1 can be filled in the usual way: filling - pre-assembly - pressurization - assembly.

In addition, even after filling the chamber 6, the inner housing 5 are latched to the chamber 6 in the valve open position, after which the chamber 6 is pressurized and locked according to relative rotation of inner housing 5 and chamber 6. It is also possible to latch the inner housing 5 after filling the chamber 6 in the valve closing position.

The sealing element 10 is constructed such that it abuts in the region of the dispensing opening 28 substantially permanently with a bias on the closure pin 7. On the one hand, this prevents that something can be deposited in the first output formation 27 between sealing element 10 and closure pin 7. On the other hand, the sealing lip 29 can offer an effective drip protection.

The sealing lip 29 has in the illustrated embodiment from the outside of a groove 30 in order to increase the flexibility further, so as little resistance is built up when the powerful discharge of the chamber contents.

FIGS. 15 to 19 show a further embodiment, in this case essentially based on the exemplary embodiment according to FIGS. 11 to 14. Again, chamber 6, drain port 13 and locking pin 7 rotatably connected to each other and a total of relatively rotatable relative to the inner housing 5, but firmly connected in the axial direction with this.

As in the embodiment described above, here too, a bead 9 which preferably runs around the outside can engage the outlet nozzle 13 in an associated annular groove 12 of the inner housing 5. As a result, the relative rotational displacement, in particular of the closure pin 7 with respect to the inner housing 5 is given. In the axial direction, however, a relative displacement is prevented. In the previous embodiment, a rotation of the cover element 4 out of the closed position in the direction of a cover removal position (initially) leads to a rotation of the chamber 6 with the closure pin 7 relative to the inner housing 5 and superimposed thereto to an axial displacement of the inner housing 5 and Chamber 6 with closure pin 7 in the direction of the lid removal, so in the embodiment according to Figures 15 to 19 at the beginning of rotation of the lid member 4 from the closed position out according to Figure 15 initially only a rotation of the closure pin 7 via the chamber 6 relative to the inner housing 5 feasible without the above axial displacement. An axial displacement of chamber 6 with closure pin 7 and inner housing 5 in the removal direction is preferably prevented until reaching an outlet position as shown in FIGS. 18 and 19.

This is achieved essentially by a freewheeling direction of the cover element 4 considered in the axial direction relative to the chamber 6. Wandungsaußenseitig the chamber 6 may be provided for this purpose in this one in the longitudinal section of Figure 15 radially outward in the direction of the Wandungsinnenfläche the cover element 4 facing stop rib 15. In the lid closure position according to FIG. 15 with an axial spacing below this stop rib 15, a driving rib 16 projecting radially inwards in the illustrated exemplary embodiment is provided on the inside of the cover element 4. The spacing between the entrainment rib 16 and stop rib 15 in the possibly sealed lid closure position according to FIG. 15 considered in the axial extension direction can, as is preferred, be adapted to the axial displacement path of the lid element 4 during a rotation thereof by approximately 180 degrees. Thus, the axial distance can be about 1 mm to 2.5 mm, further for example about 1.6 mm to 1.8 mm.

The chamber 6 is rotatably supported in the lid member 4, but linearly displaceable over the above-described measure in the lid member 4 in Achserstreckungsrichtung. For this purpose, ribs 31 extending in the axial direction on the outer side of the chamber 6 are provided, which engage with correspondingly fitted ribs 32, likewise extending in the axial direction, on the inside of the cover element 4 (see FIG.

As a result, a vertical displacement of the chamber 6 and connected to the chamber 6 elements relative to the lid member 4 is possible, while simultaneously driving the chamber 6 by the lid member 4. [00115] According to rotary displacement of the lid member 4 from the closed position shown in FIG 15 and corresponding rotational drive of the chamber 6, the closure pin 7 is also in this embodiment in the sealing element einitzend rotated into the outlet position, in which, as shown in Figures 18 and 19, the Ausgabeausformungen 26 and 27 are spent in a matching orientation. This results in the axial direction, a superimposition of the groove-like Ausgabeausformungen so that they form the flow path for dispensing the medium. In the course of this first rotary displacement over an exemplary Verdrehweg of about 180 degrees, no axial displacement of the chamber 6 and the inner housing 5 is given. This axial displacement for removing, in particular, the inner housing 5 from the container opening 3 preferably starts only when the outlet position according to FIGS. 18 and 19 is reached, with further rotation displacement of the cover element 4 and concomitant admission of the chamber-side rib 31 through the cover-side rib 32.

FIGS. 20 to 23 show a further embodiment in which, like essentially also in the embodiments described above, a chamber bottom 33 is formed by the inner housing 5 in the association state. In the embodiment shown, this chamber bottom extends in a plane aligned at an acute angle to the body axis of the closure device 1 with reference to the cross-sectional representation in FIG. The chamber bottom 33 extends peripherally over its entire circumference into a channel 34. This channel is bounded by an inner channel side wall 35 and a radially outer channel side wall 36 and by a channel bottom 37 with reference to the sectional view in FIG.

The radially inner side wall 35 merges into the chamber bottom 33, while the radially outer channel side wall 36 essentially forms the housing wall of the inner housing 5.

In particular, the surface of the channel bottom 37, moreover also the surface of the radially inner channel side wall 35 pointing in the groove space and possibly also, as shown, the surface of the chamber bottom 33 facing the chamber 6 are covered by a soft plastic layer 38 This can, as also preferred, be produced together with the inner housing 5 in the two-component injection molding process. Alternatively, the Soft plastic layer 38 separately produced as a pot-like part and, for example, latching fixed on the inside of the inner housing 5.

At least one drainage or closure opening 8 is formed in the region of the gutter bottom 37, with an opening axis which is preferably rectified to the body axis of the closure device 1, thus correspondingly aligned in a parked state of the container 2 substantially along one vertical.

The discharge opening 8 is provided as a hole, penetrating both the hard plastic material in the region of the chamber bottom 33 and the soft material in the region of the soft plastic layer 38.

As also described and illustrated with respect to the embodiments in Figures 11 to 19, also in the embodiment of Figures 20 to 23, a cooperation of closure means and sealing element in the manner of a rotary valve is given. The sealing element 10 is formed by the soft plastic layer 38. The closure means V is formed in this embodiment substantially plug-like, in particular formed by the wall of the drain neck 13th

The discharge nozzle 13 extends essentially in the manner of a circular cylinder, wherein the free, correspondingly ring-shaped, circumferential end in the usual way in the usual way dips into the groove 34 of the inner housing 5.

The closure means V, here corresponding to the annular end portion of the drain neck 13, is permanently in the sealing element 10, here the groove 34, a seated, is not correspondingly displaced relative to this in the direction of the axis. It is preferably carried out alone a displacement of the closure means V relative to the sealing element 10, in particular to the soft plastic layer 38 in Circumferential direction, this example. Stop limited over an angle of further example. 180 °.

The closure means V in this case has a (second) Ausgabeausformung 26, in the form of a radially inwardly towards the radially inner groove side wall 35 and axially downwards in the direction of the discharge opening 8 open edge groove. In the closed position according to FIGS. 20 and 21, the latter is offset by approximately 180 ° relative to a first dispensing formation 27 formed in the region of the channel side wall 35 in the direction of the channel 34. This is correspondingly formed in the area of the soft plastic layer 38.

This first output molding 27 is preferably formed in the form of a groove, in particular in the form of a groove extending in the axial direction. Further, according to the illustrated embodiment, this first dispensing formation 27 is provided axially spaced from the dispensing opening 8 in the transition from the gutter side wall 35 into the chamber bottom 33.

Correspondingly, a radial widening of the channel 34 results in the region of the first output molding 27.

As a result of rotational displacement, the plug-shaped closure means V in the channel 34 is inserted in a locking manner into the outlet position, in which, as shown in FIG. 23, the dispensing protrusions 26 and 27 are brought into a coincident orientation. A superimposition of the groove-like output formations results in the axial direction, as well as an assignment of the second output formation 26 to the discharge opening 8, so that the output formations form the flow path for dispensing the medium located in the chamber 6.
