Definitions

  • the invention relates to a closure device according to the features of the preamble of claim 1.
  • Closure devices of the aforementioned type are known in the prior art. These are used to seal a container, for example a beverage bottle, and at the same time to provide a chamber for the separate storage of liquid or powdered ingredients, for example tea essences, so that they cannot immediately be filled with the contents of the container, i.e. water for example , come into contact and/or be mixed, but only at the moment when the closure device is removed from the container. This is regularly the moment when a user wants to consume the beverage in the container.
  • a container for example a beverage bottle
  • liquid or powdered ingredients for example tea essences
  • the closure devices known in the prior art regularly consist of a cover element, on which the chamber is arranged, and an inner housing.
  • the closure device is generally screwed onto the container as a whole, ie completely preassembled.
  • the inner housing has a thread that corresponds in a form-fitting manner to the thread of the container.
  • the cover element and inner housing are connected to one another via corresponding threads with a positive fit.
  • the chamber and the inner housing have mutually corresponding closing means and opening means for closing or opening the discharge opening.
  • These corresponding closing and opening means can be designed, for example, in the form of a single plug element arranged on the inner housing, with a first end area forming the closing means and a second end area forming the opening means.
  • the plug element prevents or allows the medium to escape into the container.
  • the corresponding closing and opening means can also be separate elements, such as a membrane closing the outlet opening of the chamber and a spike arranged on the inner housing.
  • the pamphlet WO 2007/129116 A1 relates, for example, to a prior art closure device for attachment to a container.
  • the closure device includes a lid member defining a chamber and an inner housing having a plug member sealingly engageable with a vent opening in a bottom wall of the chamber.
  • the lid member is threaded for engagement with corresponding threads of the inner housing to allow the lid member to be moved relative to the inner housing from a closed position in which the plug member closes the vent opening of the chamber to a drain position in which the Plug element is at least partially withdrawn from the discharge opening, is displaced in order to release a discharge channel arranged between the chamber and the container.
  • closure devices of this type known in the prior art have proven themselves for closing plastic containers, they are not suitable for closing glass containers.
  • the known closure devices require an optimal fit and Tightness requires precise dimensioning of the container in the area of the container opening.
  • these requirements cannot be met in the manufacture of glass bottles.
  • a closure device according to the preamble of claim 1 is known, in which a plug part is provided with different O-rings at different points of the axial extension. These O-rings are in sealing engagement with an inner wall of the chamber in the sealed state as well as in the completely unscrewed state of the closure means.
  • a stopper to be handled individually for closing a bottle is known.
  • a core part is inserted here in a force-fitting manner into an enveloping part.
  • the invention is concerned with the task of specifying a closure device which has advantageous closure means.
  • the outer soft plastic assumes sealing properties, which means that a separate use of a seal in the sealing plane is no longer necessary.
  • the closure means can have a soft plastic completely or only partially, radially on the outside, optionally correspondingly partially interrupted by hard plastic areas.
  • a design can also be provided in which the chamber has a first area above the first thread means and a second area above and/or horizontally overlapping the first thread means and/or below the first thread means, with the first area is configured radially larger than the second area.
  • the second area can be limited in terms of its radial extent by restrictive dimensions of the container, in particular the container opening.
  • the second area can thus extend within a container neck in the allocation and use position.
  • the first area which extends vertically upwards at this second area, can be assigned to the container in such a way that there is no restriction with regard to the radial extent of the first area, so that it can be selected to be larger than the second area viewed transversely to a thread axis of rotation can.
  • the first area can have a radial dimension which corresponds to that of an associated container section, for example a container neck having the container opening. Furthermore, the radial dimension of the first region of the chamber can correspond to 1.2 times or more up to 5 times, preferably about 2 times, the corresponding radial dimension of the second region.
  • the chamber relative to a usage position—has a horizontal division on top of the first thread means.
  • a chamber upper part can be designed as a chamber cover by means of a horizontal division on top of the first thread means, for preferably sealing assignment to the chamber lower part after the chamber has been filled with the liquid to be stored.
  • the connection between the upper part of the chamber and the lower part of the chamber can be realized by means of a threaded screw connection or also by means of a clip or snap connection. Welding or (food-safe) gluing is also possible.
  • the horizontal division preferably relates to a usage position of the closure device or of the container, in which a longitudinal axis of the device or a longitudinal axis of the container extends in a vertical direction.
  • the parting plane can also extend transversely to a container neck axis.
  • the chamber can be composed of several parts and, with respect to a position of use of the container, continue vertically above the first thread means, a first part having an extension starting from a connection area with the second part vertically upwards and at least partially above the first thread means is arranged.
  • the chamber extends laterally above the first thread means beyond the first thread means.
  • a radial chamber expansion can be achieved above the first thread means, which overall results in a favorable increase in volume of the chamber with the same container opening or the same container neck diameter.
  • the lateral expansion of the chamber or, with reference to a device axis, the radial expansion above the first thread means can be dimensionally based on a cover element that interacts with the container neck, preferably via a thread.
  • the radial widening of the chamber above the first thread means can be oriented to the outer diameter of the container in the area of the container opening.
  • the chamber is only positively connected to the cover element. Due to the form-fitting connection, the chamber can also be displaced via the cover element when the same is rotated.
  • the chamber with the cover element can also be moved linearly along a longitudinal axis of the device or a longitudinal axis of the container opening when the cover element is rotated and/or rotated about the longitudinal axis as a result of the non-rotatable connection.
  • the chamber can have projections or ribs that protrude radially with respect to a longitudinal axis of the device, which interact with correspondingly positioned counter-form-fitting means of the cover element.
  • Such counter-positive locking means on the cover element can be molded or shaped during the production of the cover element or also formed during the course of the arrangement of the cover element on the closure device associated with the container opening, for example by rolling on when the cover element is made of aluminum.
  • an end face of the closure means facing towards the interior of the chamber is made entirely or partially of a soft plastic.
  • a material that is matched to the liquid to be stored in the chamber can also be used as a result, possibly taking into account sufficient (core) stability, which can be provided by the radially inner (harder) material.
  • the second area can have an expansion area required for adaptation to the first area, which is preferably formed integrally from the same material.
  • the expansion area extends vertically above the container opening when the container is in the usual position of use.
  • the expansion area can be designed in a step-like manner in relation to a vertical section.
  • the expansion area can also have a cone area with respect to a vertical section, in particular a cone area that slopes down radially inwards in the position of use. This achieves improved emptying of residues from the chamber, in particular from the first region of the chamber.
  • the two chamber parts can, as is also preferred, consist of plastics that can be welded to one another.
  • the two chamber parts are preferably made of identical thermoplastics.
  • the widening area of the chamber can have a radial extent which corresponds to 0.8 to 1.2 times the diameter at the root of a second thread for cooperation with the container. This is a favorable handling given to the locking device.
  • the diameter of the cover element cooperating with the second thread of the container in the area of the chamber extensions is not or not significantly increased compared to the thread area.
  • the contact surface of the cover element wall which extends essentially concentrically to the axis of rotation of the thread, is enlarged by the chamber area extending vertically beyond the container opening, which can result in reduced effort when opening the closure device.
  • the chamber may be surrounded by an outer metallic sleeve. This is more preferably non-rotatably connected to the chamber parts. This can be an aluminum sleeve.
  • the radial expansion area of the chamber is held on the sleeve even after the chamber has been removed from the container.
  • a radially drawn-in section of the sleeve can be used for this purpose in the usual position of use, vertically below the expansion area. This can be formed with a conventional rolling of the sleeve wall onto the second thread on the container side.
  • the total enclosed volume of the chamber can be 40% or more, e.g. 60% or even 80% up to 95% of the total volume above a level, which is formed by sealing means formed on the closure device for sealing on an end face a container are provided results.
  • the first thread means can also be arranged on the chamber pointing radially outwards as seen from the axis of thread rotation. Relative movement of the chamber to the inner housing may be facilitated by corresponding threads located on the chamber and inner housing.
  • the formation of the first threading means on the chamber, viewed from the axis of rotation of the thread, pointing radially outwards, makes it possible to arrange the chamber, including the thread, inside the container. Stick to it
  • the chamber and inner housing are also engaged with each other in the discharge position, so that the inner housing with the chamber arranged on the lid element can be removed from the container.
  • the fit of the closure device on the container no longer depends on precise dimensioning of the container in the area of the container opening. Rather, the tightness of the container closed with the closure device can also be ensured if the container, in particular a glass bottle, has dimensional deviations.
  • a preferably elastic seal can be arranged particularly easily between the inner housing of the closure device and the inner wall of the container in the area of the container opening.
  • This press seal can be particularly advantageously welded to the inner housing. Due to the elasticity of the press seal, dimensional fluctuations during the manufacture of the glass bottle can be compensated for so that the closure device optimally seals the container opening.
  • the cover element can furthermore be made for the cover element to be an aluminum element rolled onto the container in order to form a second thread, with the second thread formed on the cover element corresponding to a second thread of the container.
  • the aluminum element serving as the cover element is rolled onto the outer wall of the container in the area of the container opening, as a result of which the thread is stamped into the cover element.
  • Cover element and container are thus form-fitting corresponding elements that the tightness of the Ensure locking device closed container. It is also advantageous that in the production of the cover element a technology can be used which is already regularly used for closing glass bottles with aluminum lids.
  • the chamber is welded to the cover element. It is also possible here that the cover element simultaneously closes an opening formed in the chamber.
  • the cover element can thus serve both as a closure element for the opening of the chamber and as a closure element for the container itself.
  • the welding can take place in different ways, for example by means of ultrasound, induction or resistance heating.
  • the chamber thus advantageously has a type of connecting flange which is aligned essentially parallel to an adjacent surface of the cover element.
  • the collar-shaped beveled edge area can in particular be an area of the wall of the chamber that is beveled by 90°.
  • an area is created in a particularly simple manner, which is aligned parallel to the surface of the cover element.
  • the chamber can be connected to the cover element along this—preferably ring-shaped—area, ie along the opening. This area is advantageously used during the welding process in order to weld the cover element to the chamber.
  • the cover element In order to increase the adhesion between the aluminum cover element and the chamber, it is also recommended that the cover element be coated with a lacquer in the area of the weld. The composition of the lacquer must be matched to the respective material of the chamber.
  • the invention proposes that the cover element be a plastic element which has a second thread that corresponds to a second thread of the container.
  • the second thread of the cover element is not only formed when it is connected to the container, but rather already during the production of the cover element itself, ie. H. before final assembly on the container.
  • the inner housing has a press seal on the side facing away from the chamber for contact with the container in the area of the container opening. In this respect, the necessary tightness of the container screwed to the closure device is ensured.
  • the chamber has an opening with a collar-shaped edge area, to which edge area a film element is welded to close the opening, which film element is connected to the cover element.
  • the chamber is designed as a container open on one side, the opening of which points in the direction of the cover element when the closure device is in the assembled state. This opening can be used to easily close the chamber with, for example, the closure means and to equip opening means so that before the connection of chamber and cover element - as also previously possible in relation to the aluminum cover - a completely pre-assembled "chamber unit" is created, which then only has to be connected to the cover element.
  • the necessary tightness of the closure device can also be ensured by a foil element between the chamber and the cover element that additionally closes the opening of the chamber in a fluid-tight manner.
  • the foil element can be welded to at least a partial area of the chamber and at least a partial area of the cover element.
  • the connection between the foil element and the cover element can also be made by other technologies, for example by gluing or the like.
  • a welding process it can be provided that either all three parts—chamber, film element, cover element—are welded together essentially at the same welding points, in particular simultaneously, or alternatively that the welding points differ locally. The latter is particularly useful when the melting points of the materials of the cover element and the chamber are so different that there is a risk that one of the materials will be heated above its melting point. In this case, it is advisable to locally separate the spot welds.
  • the cover element and foil element can be welded to one another in the area of the opening of the chamber, while the chamber and foil element are welded to one another in the area of the collar-shaped edge area of the chamber.
  • the material of the cover element is regularly PP (polypropylene). PP has a melting point of approx. 210°C.
  • the material of the chamber PBT (polybutylene terephthalate), has a melting point of approx. 320°C.
  • the chamber and the film element should therefore advantageously be welded to one another independently of the cover element, so that the material of the cover element is not impaired.
  • the cover element and the film element can then be welded to one another separately in terms of time and location.
  • the location of the welded connection of the cover element and foil element is then not defined in the area of the collar-shaped edge area, but can in principle lie in the entire contact area of cover element and foil element, for example also in the area of the opening of the chamber.

  • the inner housing 5 together with a press seal 11 arranged on the inner housing 5 is pressed into the container opening 3 .
  • the chamber 6 with the cover element 4 arranged thereon is introduced into the inner housing 5 , the chamber 6 and inner housing 5 being screwed together by means of the corresponding first thread means 10 .
  • the cover element 4 is simultaneously also rolled onto the second thread 12 of the container 2 , a second thread 12 also being formed in the cover element 4 .
  • the welding of the chamber 6 and the cover element 4 can only take place when the cover element 4 has been screwed to the container 2 .
  • FIG 7 shows an alternative embodiment of a closure device 1 according to the invention.
  • the cover element 4 of this closure device 1 is preferably made of a plastic, for example PP (polypropylene) or PE (polyethylene).
  • the basic structure of the closure device 1 is similar to that in figure 5 shown.
  • the cover element 4 is not made of aluminum but rather of a plastic, it is not possible for the cover element 4 to roll onto the container 2 .
  • the chamber 6 is closed in the area of its opening 13 with a foil element 15 .
  • This foil element 15 is advantageously an aluminum foil, but can also consist of a plastic material, for example EVOH (ethylene vinyl alcohol copolymer), PET (polyethylene terephthalate) or the like.
  • the film element 15 consists of aluminum, it is preferably coated on the side pointing in the direction of the chamber 6 with a lacquer for the material of the chamber 6, in particular PBT.
  • a lacquer is advantageously applied, which is suitable for connection to the cover element 4 .
  • the cover element 4 consists of PP, for example, a lacquer for PP is recommended.
  • the film element 15 is welded to the chamber 6 or the cover element 4 .
  • the welding can be done either in a common process step, or in successive steps, the film element 15, for example, first to the Chamber 6 is welded, and only in a subsequent step to the cover element 4.
  • closure device 1 already has a second thread 12 formed on the cover element 4 for connection to the container 2 .
  • closure devices 1 according to figures 6 and 7 are shown in a closed position.
  • the container 2 is connected to the closure device 1 in a fluid-tight manner, i.e. the closure means 7 is located within the outlet opening 8 of the chamber 6 in such a way that the medium stored in the chamber 6 cannot flow out through the outlet channel 16, but rather is enclosed in the chamber 6 is.
  • figure 8 shows, for example, the closure device 1 according to FIG figure 6 in a release position. Although the drain position here in relation to figure 6 is shown, this can just as in a closure device 1 according to figure 7 be executed.
  • the closure device 1 according to figure 8 thus serves only as an example of the discharge position and is in no way limiting.
  • the cover element 4 and the container 2 are to be removed from one another in order to realize a discharge position.
  • This longitudinal displacement of the cover element 4 and container 2 simultaneously also causes the chamber 6 arranged on the cover element 4 and the inner housing 5 arranged on the container 2 to be displaced relative to one another. Since the closing means 7 or the opening means 9 on the inner housing 5 are arranged, the displacement of the chamber 6 relative to the inner housing 5 also causes a displacement of the closing means 7 or the opening means 9 within the discharge opening 8 of the chamber 6. This results in the release of the discharge opening 8, so that the Medium stored in chamber 6 can flow through the outlet opening 8 and the outlet channel 16 formed within the opening means 9 into the container 2 .
  • the corresponding second threads 12 formed on the lid element 4 and the container 2 are rotated in relation to one another. At the same time, this rotation causes the chamber 6 to rotate within the inner housing 5 . This rotation is made possible by the first thread means 10 formed on the chamber 6 and the inner housing 5 . Because the inner housing 5 is firmly pressed into the container 2 by means of the press seal 11, the inner housing 5 remains firmly connected to the container 2 while the cover element 4 is being unscrewed from the container 2 or during the rotation of the chamber 6 within the inner housing 5.
  • the chamber 6 is first moved relative to the inner housing 5 so that the chamber 6 simultaneously moves past the closing means 7 or opening means 9 connected to the inner housing 5 .
  • a portion of the discharge opening 8 is opened between the closure means 7 and the inner housing 5, so that in the Chamber 6 stored medium can flow through the outlet channel 16 of the opening means 9 into the container 2.
  • figure 9 shows a subsequent position: As the chamber 6 is progressively raised, the upper end region of the closure means 7 can move into a position relative to the discharge opening 8, in which position the discharge opening 8 is closed again, so that medium is prevented from dripping out of the chamber 6.
  • the upper end area of the closure means 7 is regularly expanded radially in relation to the adjacent areas of the closure means 7 . This position is optional.
  • the second threads 12 of the lid element 4 and the container 2 separate from each other, while the first thread means 10 of the chamber 6 and the inner housing 5 are in an end position. Chamber 6 and inner housing 5 cannot rotate any further in relation to one another in this end position.
  • FIG 10 shows the closure device 1 completely removed from the container 2.
  • the closure means 7 secures the discharge opening 8 of the chamber 6 against dripping of the medium from the chamber 6.
  • figure 11 shows an embodiment based on the in figure 1 illustrated embodiment, the volume of the expansion area (first chamber area A) being increased compared to this. This is achieved according to a compared to the version in 1 in the vertical direction, i.e. along the axis of rotation of the thread 18, in particular the wall of the chamber upper part 6".
  • a volume fraction of about 60% in the first area A compared to the total volume results in the embodiment according to FIG figure 11 a partial volume in the first area A of about 80%, preferably with the same outer diameter in the expansion area.
  • the second area B transitions into a cone area 25 (expansion area 28) approximately at the height of the flange 22 on the inner housing side, with reference also to the valve closed position shown.
  • the cone area 25 widens radially outwards and, in the normal state of use, vertically upwards.
  • the chamber upper part 6" is fixed.
  • the cone area 25 is supported via one or more struts 26 either directly on the flange 22, which also extends over the end face of the container 2, and/or on a flange section 27 of the chamber 6 or the chamber lower part 6′, which is in the basic position according to figure 11 on the flange 22 is supported.
  • FIG 12 shows a further alternative embodiment of a closure device 1 according to the invention.
  • the cover element 4 of this closure device 1 is preferably made of a plastic, for example polypropylene or polyethylene.
  • the basic structure of the closure device 1 is similar to that in figure 11 shown.
  • the cover element 4 is not made of aluminum but rather of a plastic, it is not possible for the cover element 4 to roll onto the container 2 . Rather, a counter-thread designed for the second thread 12 is provided directly on the cover element 4 .
  • the non-rotatable connection between the cover element 4 and the chamber wall, in particular the upper part 6" of the chamber, can be achieved by gluing or welding.
  • the wall of the chamber area B merges into the wall of the chamber area A of the same material and in one piece, with a chamber ceiling of area A being closed by a foil element 15, for example aluminum foil.
