Description

BACKGROUND OF THE INVENTION

The present invention relates to a closure cap, preferably a screw cap, for mounting cm a liquid container, preferably a bottle, more preferably a PET bottle, wherein the closure cap at least comprises

• • a preferably recloseable spout opening,
  • a receiving element for receiving at least one dispensing body, preferably at least one tablet, wherein the receiving element is permeable to a liquid in order to allow the at least, one dispensing body to come into contact with the liquid,
  • an opening for introducing the at least one dispensing body into a receiving volume or for removing it from the receiving volume.

The present invention also relates to a dispensing body, preferably a tablet for mixing with a liquid which is situated in a liquid container sealed with the closure cap in accordance with the invention.

The invention finally relates to a system containing at least one closure cap in accordance with the invention and at least one dispensing body in accordance with the invention.

DESCRIPTION OF THE PRIOR ART

In order to enable the intake of liquid on the road or during sports, drinking bottles are known, especially drinking bottles with a closure cap. The drinking bottles usually comprise a thread onto which the closure caps are screwed. The threads are standardized and the number of the different standardized threads of said drinking bottles is low. These bottles can be prefilled on the one hand, e.g., with mineral water, which can also be mixed with flavors, or with an isotonic beverage. On the other hand, bottles can be concerned which are designated to receive a liquid mixed by the user as required. In this case, effervescent powders in powder form or tablet form are available in addition to fruit juice syrups.

It is disadvantageous in both cases that the user is fixed to the specific beverage mixture for the entire duration of use of the beverage, i.e. between the start and the end of the consumption of the beverage, which means the user is no longer able to change the flavor during the consumption of the beverage, because the liquid still contained in the bottle only comprises the once selected flavor.

However, not only the desire for a specific flavor can change during the start and the end of the consumption of the beverage. If the user has decided on a non-isotonic beverage for example and wishes to have an isotonic beverage after a specific period of time in which the user has practiced sports, this is also no longer possible with the liquid still present in the bottle.

In the case of preparing the beverage by means of effervescent tablets, the use of chemicals for dissolving the effervescent tablet is required, which means the use of entirely natural substances for preparing the beverage is not possible in this case, which can be regarded as disadvantageous.

It may further occur with respect to effervescent powders and also effervescent tablets that the powder or the tablet is not dissolved completely and portions of the powder or the tablet reach the user's mouth, which is perceived as highly unpleasant.

Incomplete dissolution can also be caused by sub-optimal dosing, especially an excessive concentration of the effervescent powder or tablet. Maintaining the correct dosage is usually not always easy because the specifically existing quantity of liquid needs to be considered in mixing the powder or the tablet with the liquid, which is usually water.

These disadvantages can be remedied at least in part according to U.S. 2010/0012193A1. It describes a liquid container with a closure cap which is formed in three parts, i.e. a tablet container, a container lid and a closure cap closure. The container lid must be screwed off and subsequently screwed on again for the insertion of a tablet into the tablet container. It is disadvantageous that the container lid can be dropped or lost.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a closure cap for liquid containers which allows admixing flavors and/or nutrients and/or dietary supplements and/or medical compounds into a liquid that can be received in the liquid container by avoiding the aforementioned disadvantages. In particular, simple handling shall be guaranteed which allows a simple exchange of the flavors and/or nutrients and/or dietary supplements. Furthermore, dosing problems, especially too high concentrations of flavors and/or nutrients and/or dietary supplements in the liquid, shall be prevented. The possibility for avoiding chemicals shall further be provided in this case, so that natural substances can be used for admixing.

SUMMARY OF THE INVENTION

This object is achieved by a closure cap, preferably a screw cap, for mounting on a liquid container, preferably a bottle, more preferably a PET bottle, wherein the closure cap at least comprises

• • a preferably recloseable spout opening,
  • a receiving element for receiving at least one dispensing body, preferably at least one tablet, wherein the receiving element is permeable to a liquid in order to allow the at least one dispensing body to come into contact with the liquid,
  • an opening for introducing the at least one dispensing body into a receiving volume or for removing it from the receiving volume.

It is provided that the receiving element can be actuated in the operating position of the closure cap and can be brought through the opening both from the receiving volume to a loading position for changing the dispensing body and also to a dispensing position in the receiving volume.

The dispensing body can thus be exchanged without having to separate the closure cap from the liquid container. The receiving element can thus laterally be actuated on the closure cap, e.g. in the direction normally to the longitudinal axis of the closure cap. The opening is also situated laterally on the closure cap. In the loading position, the opening is open for introducing the dispensing body, the receiving element is removed at least partly from the receiving volume, so that a dispensing body situated on or in the receiving element can be removed and/or a dispensing body can be placed on or into the empty receiving element (or she receiving element can be exchanged entirely). In the dispensing position, the opening for introducing the dispensing body is closed. Liquid which flows from a liquid container into the closure cap attached thereto can only exit, then from the closure cap through the spout opening or through a mouthpiece attached thereto. The opening for introducing or removing the dispensing body is then also closed in a liquid-tight manner.

The liquid container, which is sealed with the closure cap in accordance with the invention and is preferably formed as a PET bottle, comprises a conventional spout or bottle opening, which is sealed by the closure cap in the operating position. The closure cap preferably concerns a screw cap which fits all standardized water bottles, or it is possible to use the low number of differently standardized types of bottle threads with the low number of different closure caps. The closure cap is usually provided with a mouthpiece which seals the spout opening of the closure cap and can be transferred from a closure position or closed position to a release position or open position, preferably by displacing the mouthpiece. In the closed position, no liquid can pass through the closure cap via the mouthpiece. In the operating position, secure storage of the liquid in the liquid container is enabled with the closure cap in accordance with the invention, even when it is transported or carried along by the user during sports activities. In the release position, liquid can pass through the closure cap and the user is thus able to drink.

The receiving element is arranged and releasably fixed in the dispensing position within the receiving volume, which in addition to the walls of the receiving element is bounded by the inner walls of the closure cap. This arrangement allows that liquid flows through the receiving element primarily during the drinking process when the liquid container is guided to the mouth of the user. If at least one dispensing body is arranged in the receiving element, liquid flows around the same during drinking and can supply substances, especially flavors and/or nutrients and/or dietary supplements and/or medical compounds, to the liquid, i.e. a mixture occurs with the liquid directly before the user actually drinks the mixture. A too high concentration of the desired substances in the liquid can thus principally be prevented.

Notice must be taken in this respect that after removing the liquid container (the bottle) after the drinking process a specific portion of the liquid will generally flow back into the liquid container from the receiving element. A specific proportion of the aforementioned, substances can be transferred to the remaining liquid situated in the liquid container, which needs to be considered in the configuration of the dispensing body or its dispensing characteristics.

In order to prevent that the dispensing body drops out of the receiving volume, the receiving volume (irrespective of the specific shape of the receiving volume) is preferably enclosed on all sides. Permeability for liquid is provided in this case, which can be realized by small openings for example, so that an enclosure on all sides of the receiving volume is still present. The enclosure of the receiving volume on all sides can be provided by the receiving element itself or by the receiving element in cooperation with another part of the closure cap.

In order to achieve cost-effective production of the closure cap, the receiving element and/or other parts of the closure cap can be made of plastic.

The permeability of the receiving element for the liquid is realized in a preferred embodiment of the liquid container in accordance with the invention in such a way that the receiving element comprises through-openings, which are preferably arranged in a lattice-like or grid-like manner. It is thus further reliably prevented that the dispensing body or parts of the dispensing body reach the liquid container after drinking.

Potential contact of the dispensing body with the liquid already prior to drinking principally depends on the arrangement of the receiving element in the closure cap. Contact can be prevented in the case of a perpendicularly standing liquid container when the receiving element is entirely situated in a volume formed by the closure cap. This means the volume that is bounded on the one hand by the closure cap and on the other hand by an imagined surface area which is bounded on its part by an edge of the closure cap. Said imagined surface area is actually free from material in order to enable the connection of the closure cap with the liquid container, especially in order to enable it to be screwed onto said container. This means that in this case contact of the closure cap only occurs during tilting of the bottle, as performed by the user during the drinking process. It is thus accordingly provided in a preferred embodiment of the liquid container in accordance with the invention that the entire receiving element is arranged in the dispensing position in a volume formed by the closure cap.

In order to ensure that the receiving element does not drop out of the closure cap in the loading position and is lost or soiled, it is provided in a further preferred embodiment of the liquid container in accordance with the invention that the receiving element is fastened to the closure cap, preferably releasably fixed thereto. If the receiving element can be drawn similar to a drawer from the closure cap, a securing means could be provided which during normal use prevents the full extraction and can be overcome by specific measures for the purpose of cleaning the receiving element for example. One embodiment of the invention provides that the opening can be closed in a liquid-tight manner by the receiving element in the operating position of the closure cap (in order to enable the introduction of the at least one dispensing body into a receiving volume or the removal of said body from said receiving volume). In this case, no separate closure is required for this opening; the receiving element itself is used as the closure for the opening. In particular, a liquid-tight region of the receiving element in the dispensing position of the receiving element can form, a portion of the jacket surface of the closure cap, i.e. the externally visible surfaces of the closure cap and the receiving element therefore continuously converge into each other. As a result, the receiving element forms a common outer surface with the closure cap, and there are no projections or depressions where dirt can accumulate.

It is obvious that it would also be possible to close the opening with a flap or a slide fixed to the closure cap once the receiving element has been brought to the dispensing position.

The actuation of the receiving element can advantageously be configured in such a way that the receiving element is displaceable relative to the closure cap, especially along a straight line. The receiving element can thus be pulled out from the closure cap similar to a drawer or it can be pushed into said cap. The direction of displacement can especially be normally to the longitudinal axis of the closure cap rotational axis in the case of substantially rotationally symmetrical closure caps or identical to the rotational axis of the bottle on which the closure cap is fastened, or the direction in which the liquid enters the closure cap). Respective guides for the translatory movement such as depressions (grooves) or bulges can be provided on the inner side of the closure cap.

Alternatively, the receiving element can be twistable relative to the closure cap, especially about an axis parallel to the longitudinal axis of the closure cap.

Combinations of translatory and rotational, movement of the receiving element during insertion into or extraction from the closure cap can also be considered.

An especially simple and convenient filling of the receiving element can be realized in that the receiving element is formed like a drawer, which can be pushed from the outside into the corresponding opening in the closure cap and can also be pulled out again from the corresponding opening. This means that for filling the receiving element it is pulled out of the corresponding opening, at least one dispensing body is placed in the receiving element, and the receiving element is then pushed back into the corresponding opening again. One receiving element is therefore preferably provided, which comprises a bottom surface and a jacket surface (but no top surface which sears the receiving element), wherein through-openings are arranged on the bottom surface. A further element with through-openings for a liquid is arranged between the receiving element and the spout opening of the closure cap, so that the dispensing body or parts thereof cannot reach the mouthpiece. In order to facilitate the actuation (extraction and pushing in, and/or twisting) of the receiving element, a respective auxiliary apparatus can further be provided on a jacket surface of the receiving element.

In order to achieve a simple and thus cost-effective production method for the container in this case, it is provided in a further preferred embodiment that the auxiliary apparatus comprises a depression and/or a projection in the jacket surface. The depression or the projection allows comfortable gripping of the container by the user.

If the receiving element comprises a top surface with through-openings so that the receiving volume is completely surrounded by jacket surface, top surface and bottom surface, the receiving element with the dispensing body situated therein can be produced and sold as a unit. The jacket surface, top surface and bottom surface can be connected to each other in a non-detachable manner, so that the unit represents a disposable product which after use is replaced by a new unit consisting of the receiving element and dispensing body.

A dispensing body, preferably in form of a tablet, is provided for receiving in a receiving volume of a closure cap in accordance with the invention in order to ensure simple handling and an optimal dosing possibility when using the closure cap in accordance with the invention.

Accordingly, the use of a dispensing body, preferably a tablet, is provided in accordance with the invention in a receiving element of a closure cap in accordance with the invention.

In order to enable producing a beverage when making contact with the liquid or to release flavors and/or nutrients and/or dietary supplements and/or medical compounds and thus mix them into liquid, it is provided according to a preferred embodiment of the dispensing body in accordance with the invention that the dispensing body may comprise at least one water-soluble element for producing a beverage and/or for releasing a flavor and/or a nutrient and/or a dietary supplement and/or a medical compound. The nutrients comprise carbohydrates, minerals and vitamins. If several carbohydrates, minerals and vitamins are released, the production of an isotonic, beverage is thus possible.

In order to ensure that the dispensing body can be accommodated in the receiving volume of the receiving element, the dispensing body comprises a dispensing body volume which is not greater than a receiving volume of the receiving element. In particular, the dispensing body will have dimensions which enable the receiving element to be pushed through the opening. In other words, there must be a greatest cross-section of the dispensing body which is smaller than the cross-section of the opening of the closure cap, through which opening the receiving element can be brought to a loading or a dispensing position.

In order to guarantee a spatially stable arrangement of the water-soluble elements, which additionally contributes to ensuring that no water-soluble elements can reach through the passage openings of the closure cap, they can be arranged in a sponge for example which fills the dispensing body volume at least in part. It is accordingly provided in a preferred embodiment of the dispensing body in accordance with the invention that the dispensing body comprises a sponge, preferably a plastic sponge. Said plastic sponge can especially preferably be formed in such a way that the liquid can easily reach the water-soluble elements, which can be achieved for example by a sponge fabric made of coarsely woven fibers.

In order to further improve handling, it is provided in a preferred embodiment of the dispensing body in accordance with the invention that the dispensing body comprises a liquid-permeable net-like fabric, especially game, which retains the dispensing body in a dispensing body shape which preferably corresponds to a receiving volume shape of the receiving element. The thus stabilized dispensing body shape especially allows simple and convenient changing of the dispensing body after the drinking process, once the water-soluable elements have already been dissolved entirely or at least partly. The variant in the embodiment in which the dispensing body shape corresponds to the receiving volume shape of the receiving element further ensures an especially stable arrangement of the dispensing body in the receiving element or its receiving volume.

Especially good stabilization of the dispensing body shape in combination with simultaneously simple producibility can be achieved in that the net-like fabric is arranged on an exterior side of the dispensing body.

In order to avoid the use of chemicals and only use natural substances for the preparation of the beverage, it is provided in a preferred embodiment of the dispensing body in accordance with the invention that the at least one water-soluble element concerns a ball arranged in the dispensing body volume, whose surface is formed by a water-soluble layer and whose interior is filled with a substance such as syrup or tea, which contains a flavor and/or a nutrient and/or a dietary supplement and/or a medical compound. The water-soluble layer is formed in this case from a water-soluble icing, especially sugar icing, which contributes to the avoidance of chemicals.

The time progression of the delivery of the substances, especially the flavors and/or the nutrients and/or the dietary supplements and/or the medical compounds, can be realized by several balls with different icing layer thicknesses. The balls with the thinnest icing layer thicknesses release the substances first, whereas balls with thicker icing layer thicknesses do not release any substances yet. Only at a later point in time when the substances of the balls with the originally thinner icing layer thickness have been consumed will the balls with the originally thicker icing layer thicknesses release the substances stored in them.

They can concern the same substances for example as before, so that a temporarily constant concentration of these substances is achieved in the liquid. It is also possible to provide different substances in the balls, so that a beverage with fruit flavor is provided at first and an isotonic beverage at a later point in time. This allows athletes to drink different beverages over time by carrying along only one single liquid container, wherein an isotonic beverage is also included in this case.

That is why it is provided in an especially preferred embodiment of the dispensing body in accordance with the invention that several balls with the same substance or different substances are arranged in the dispensing body volume, wherein the water-soluble layers of the balls have different layer thicknesses, especially in order to enable continuous dispensing of the substance or substances.

Finally, the closure cap in accordance with the invention and the dispensing body in accordance with the invention shall be regarded as a system which allows simple production of beverages or the adding of flavors and/or nutrients and/or dietary supplements and/or medical compounds to a liquid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows a liquid container in form of a bottle 5 with a closure cap 7. The closure cap 7 is shown in an operating position 8, in which the closure cap 7 seals a spout opening 9 of the bottle 5, The closure cap 7 is screwed onto the bottle 5 by means of a thread 34 (see FIG. 2). Surface structures 35 (not shown) which have the form of indentations (see FIG. 4) can assist a user in fastening the closure cap 7 to the bottle 5.

The closure cap 7 is provided with a mouthpiece 33 which is shown in FIG. 1 in a closure position 11. In the closure position 11, the closure cap 7 is impermeable to a liquid 37, which is accommodated in the bottle 5 and has a liquid level 38. The mouthpiece 33 can be brought from the closure position 11 to a release position (not shown) by displacing the mouthpiece 33 along a longitudinal axis 10 (see FIG. 2). In the release position, the closure cap 7 is permeable to the liquid 37 in order to allow the user to drink from the bottle 5.

The bottle 5 comprises interior walls 6, which jointly delimit a volume 4 with the closure cap 7 in the operating position 8. A receiving element 1 is arranged in accordance with the invention in said volume 4, which receiving element can be pushed into the closure cap 7. FIG. 2 illustrates such an embodiment on the basis of an axonometric view of an exposed section of the closure cap 7. FIG. 3 shows the associated receiving element 1 which is pulled out of the closure cap 7. The receiving element 1 comprises a receiving volume 20 with an approximately cylindrical receiving volume shape. The receiving element 1 is only shown schematically in this case and will be explained below in closer detail.

The receiving volume 20 allows accommodating at least one dispensing body, preferably at least one tablet 2 (see FIG. 18), which can come into contact with the liquid 37 accommodated in the bottle 5, especially during the drinking process. A beverage can thus be produced or substances such as flavors and/or nutrients and/or dietary supplements and/or medical compounds can be supplied to the liquid.

In the illustrated case, the receiving element 1 consists of a bottom surface 16 and a jacket surface 17 which surrounds the bottom surface 16. The bottom surface 16 comprises through-openings 15, which can be formed from a lattice for example. The receiving element 1 does not comprise any top surface, i.e. it is upwardly open so that a tablet 2 can be inserted simply from above. In order to ensure that the tablet 2 or parts thereof cannot leave the receiving volume 20 in the upward direction towards the mouthpiece 33, a further element 13 with through-openings 15 for a liquid is arranged in the closure cap 7 between the receiving element 1 (in the—closed-loading position) and the spout opening 9 (or the mouthpiece 33). The further element 13 is arranged in this case directly above the receiving element 1, so that the receiving volume 20 is enclosed on all sides and corresponds to the free volume within the receiving element 1. The bottom element 16 and the further element 13 are flat in this case and arranged in parallel with respect to each other.

The liquid 37 can pass into the receiving volume 20 through the through-openings 15 of the bottom surface 16 and the element 13 at least during the drinking process and thus come into contact with the tablets 2 situated in the receiving volume 20. As is shown in FIGS. 2 and 3, the through-openings 15 are arranged in regular configuration, thus producing a grid or lattice pattern. The through-openings 15 enable the production of a beverage or the dispensing of substances, especially flavors and/or nutrients and/or dietary supplements and/or medical compounds, from the tablets 2 to the liquid 37.

In order to ensure that the receiving element 1 can precisely assume its dispensing position, guide devices are provided on the inner side of the jacket of the closure cap 7, i.e. a groove 14 in this case. The actuation of the receiving element 1 is supported by an auxiliary apparatus 18, i.e. a projection 19.

FIG. 4 shows an alternative embodiment of the closure cap 7, which can be screwed onto all standardized water bottles, especially PET bottles, by means of the thread 34. In order to help the user to unscrew and screw off the closure cap 7, the closure cap 7 has a surface structure shown in FIG. 4, which in this case is formed as fluting. Furthermore, the closure cap 7 of FIG. 4 comprises a cover 3 which is removable or can be folded away, and by means of which the mouthpiece 33 can be covered, as shown in FIG. 5.

FIG. 5 shows an axonometric view of the exposed section of the closure cap 7 of FIG. 4; the associated receiving element 1 is pulled out and shown in FIG. 6.

In contrast to the variant shown in FIGS. 1 to 3, the closure cap 7 of FIGS. 4 to 6 shows a greater extension along the longitudinal axis 10. This creates more space for the opening 12, which with respect to its dimensions and shape is formed corresponding to the receiving element 1 or its receiving volume 20 shown in FIG. 6.

In both embodiments, the receiving element 1 is entirely situated in a volume which is formed solely by the closure cap 7. This means a volume which on the one hand is bounded by the closure cap 7 and on the other hand by an imaginary surface which is bounded on its part by an edge 40 of the closure cap 7. Said imaginary surface is actually free from material in order to enable the connection of the closure cap 7 with the bottle 5 (see FIG. 1), preferably by a screwed connection by means of the thread 34.

The receiving element 1 of FIG. 6 is formed in an approximately cylindrical, manner and again comprises a bottom surface IS and a jacket surface 17. The receiving element 1 can thus be pushed like a drawer into the corresponding opening 12 of the closure cap 7 or be pulled out from said opening 12, even when the closure cap 7 is in the operating position. If the closure cap 7 is in the operating position 8, the receiving element 1 is Inserted in this manner through the corresponding opening 12 into the closure cap 7 or removed therefrom. Accordingly, the user need not unscrew the closure cap 7 from the bottle 5 for filling the receiving element 1 with tablets 2. The bottom surface 16 faces away from the mouthpiece 33 when the receiving element 1 is pushed into the corresponding opening 12 of the closure cap 7.

The receiving element 1 is only shown schematically in this case and will be explained below in closer detail.

A (circular) element 13 with through-openings 15 which terminates the receiving volume 20 is situated directly above the inserted receiving element 1.

The receiving element 1 in FIG. 6 can also comprise a removable top surface, which can be folded upwardly for example, and is provided with through-openings 15, so that the receiving volume 30 is enclosed on all sides by the receiving element 1 itself. The element 13 can then be omitted in this case.

The receiving element 1 for the embodiment according to FIGS. 4 to 5 could also be arranged as in FIG. 17, where the receiving volume 20 is completely surrounded by the receiving element 1 itself, namely by the cylindrical jacket surface 17 which is impermeable to liquid and by the bottom surface 16 which is permeable to liquid, and by the top surface 21. The element 13 in the closure cap 7 can be omitted again as a result of the top surface 21. A dispensing body 2 could be inserted into the receiving element 1 according to FIG. 17 prior to the closure on the production side and the receiving element 1 can be closed in a non-releasable manner. Once the dispensing body 2 is consumed or a different dispensing body is desired, a different dispensing body 1 with a different (e.g. unconsumed) dispensing body 2 is inserted.

In order to enable the convenient insertion of the receiving element 1 into the opening 12 or the removal thereof from the opening 12, the receiving element shown in FIG. 6 comprises an auxiliary apparatus 18 in form of a projection 19 on the jacket surface 17 on which the user can act on the receiving element 1. It is understood that the auxiliary apparatus 18 can further comprise further elements, e.g. a depression (not shown) in the jacket surface 17.

In order to avoid endangering the tightness of the closure cap 7 when the receiving element 1 is inserted, no through-openings 15 are provided in the jacket surface 17, but only through-openings 15 in the bottom surface 16.

FIG. 7 again shows a closure cap 7 of the same type as that of FIG. 4. The closure cap 7 is formed cylindrically in the region of the receiving element 1. A receiving element 1 is provided in FIG. 7 however, which seals the opening 12 in the dispensing position in a liquid-tight manner by means of its jacket surface 17 which in this case is a part of the cylinder jacket, as shown in FIG. 8. The jacket surface 17 thus forms a part of the jacket surface 36 of the closure cap 7.

The receiving element 1 which fits FIG. 7 can consist, as in FIG. 9, of the semi-cylindrical jacket surface 17, a bottom surface 16 which is permeable to liquid and a top surface 21 which is permeable to liquid, wherein the bottom and top surface 16, 21 adjoin the jacket surface 17 of the receiving element 1, and adjoin the jacket surface 36 in the dispensing position when the receiving element 1 is completely inserted into the closure cap 7. As a result, a dispensing body (tablet) 2, which is situated in the receiving volume 20, is completely enclosed therein. The entire dispensing body 2, or parts thereof, cannot reach the mouthpiece 33, which is covered in this ease by the cover 3.

As an alternative to FIG. 9, the receiving element 1 of FIG. 7 can also be formed without the top surface 21, as shown in FIG. 10. In this case however, a further element 13 with through-openings must be arranged in the closure cap 7 between the receiving element 1 and the spout opening 9 or mouthpiece 33, as shown in FIG. 5.

FIGS. 11 and 12 again show a closure cap 7 of the same type as that of FIG. 4 and FIG. 7, wherein a receiving element 1 is shown here (see FIG. 13) which does not assume the entire width of the closure cap 7. The receiving element 1 has a substantially rectangular shape in this case, wherein a part of the jacket surface 17 (which is a narrow side in this case) forms the liquid-tight termination of the opening 12 in the jacket surface 36 of the closure cap. The remainder of the jacket surface 17 is situated within the jacket surface 36 in the dispensing position of the receiving element 1.

The receiving element 1 comprises a liquid-permeable fiat top surface 21 and a bottom surface 16. In order to ensure that the liquid can not flow past the receiving element 1, a barrier (baffle plate) 33 is provided in the interior of the closure cap 7 in the region of the height extension of the receiving element 1, which barrier closes the cross-section of the closure cap 7 between the receiving element 1 (in the dispensing position) and the jacket surface 36 of the closure cap 7 (see FIG. 14). Guides (bulges, grooves) can be attached to the barrier (baffle plate) 33 and/or at further locations on the inner side of the closure cap 7, which guides interact with respective guides on the receiving element 1 and along which the receiving element 1 can be pushed into the closure cap 7 or be extracted therefrom.

Guides can generally be provided on the receiving element 1 and/or on the inner side of the closure cap 7 for all embodiments with displaceable receiving element 1.

The receiving element 1 in FIG. 13 could comprise an upwardly foldable cover surface 21, so that the dispensing bodies 2 can be changed. It would also be possible to produce receiving elements 1 as disposable products where the receiving volume 12 is not accessible and the dispensing body 2 is thus not removable (bottom surface 16 and top surface 21 are non-releasably connected to the jacket surface 17), and the entire receiving element 1 would have to be exchanged in order to insert a different dispensing body 2.

The receiving element 1 in FIG. 13 could be formed without the top surface 21, wherein the receiving volume 20 would then have to be sealed with a further element 13 similar to FIG. 2.

FIGS. 15 and 16 again show a closure cap 7 of the same type as the one of FIGS. 4, 7 or 11. The receiving element 1 is now twistably fastened by means of a hinge 41 to the closure cap 7, which hinge is arranged in this case parallel to the longitudinal axis 10 of the closure cap 7. The hinge 41 could be fastened to a perpendicular web on the closure cap 7, which web is arranged outside of the jacket surface 36. The receiving element 1 can be actuated by means of the projection 19, i.e. it can be folded out or twisted horizontally.

The receiving element 1 can now be arranged in such a way that its jacket surface 17 surrounds it entirely (i.e. it has the shape of a cylinder jacket in this case), and in the dispensing position (FIG. 15) the jacket surface 17 terminates at the top and bottom in a liquid-tight manner with the jacket surface 36 of the closure cap 7. The opening 12 of the closure cap would be shaped in the manner of a cylinder jacket in this case, and in the operating position 8 of the closure cap 7 the entire jacket 17 of the receiving element 1 would seal it in a liquid-tight manner.

The receiving element 1 itself can surround the receiving volume 20 again, by means of the top surface 21 and the bottom surface 16. It could then also be considered that the receiving element 1 is equipped on the production side already with a dispensing body 2, and the jacket surface 17, the top surface 21 and the bottom surface 16 are connected to each other in a non-releasable manner. The receiving element 1 would then be a disposable product. The receiving element would then have to be disengaged from the hinge 41 for changing the dispensing body 2 and a new receiving element 1 with a dispensing body 2 situated therein would have to be mounted in the hinge.

The receiving element 1 can also be formed without the top surface 21. In this case however it is necessary to arrange a further element 13 again between the receiving element 1 and the spout opening 9, similar to FIG. 2.

The receiving element 1 (and the jacket 36 of the closure cap 7) can also be arranged as shown in FIGS. 9 and 10. In the case of FIG. 9, the hinge 41 would then act on a perpendicular end of the jacket surface 17. A dispensing body 2 could be inserted between the bottom surface 16 and the top surface 21 in the loading position, where no jacket surface 17 is present. In the case of FIG. 10, a dispensing body 2 can be placed conveniently from above on the bottom surface 16 as a result, of the missing top surface 21. A further element 13 in the closure cap 7 would then terminate the receiving volume 20 at the top. The jacket surface 17 would seal the opening 12 in a liquid-tight manner both in the embodiment according to FIG. 9 and also according to FIG. 10.

The receiving elements of FIGS. 4 to 16 can obviously also be used for other types of closures under respective adjustment of the closure cap and the receiving element. A receiving element 1 that can be twisted out of the closure cap as shown in FIGS. 15 and 16 or a narrower receiving element 1 as shown in FIG. 13 could also be used for example for a closure cap of FIG. 1.

Generally, all embodiments of receiving elements, irrespective of whether they are twistable or displaceable, can also be arranged in such a way that they do not form any part of the jacket surface 36 of the closure cap 7 in the dispensing position. For this purpose they would have to be dimensioned in a smaller way normally to the longitudinal axis. In this case, the opening 12 in FIG. 16 would be partly sealed for example by the jacket surface 36 of the closure element 7 (as in FIG. 8). The remaining opening 12 could be sealed in a liquid-tight manner by a flap (a slide, etc) which can be linked to the exterior side of the closure cap 7 in order to prevent loss of the flap. The flap can form a part of the jacket surface 36 of the closure element.

In all embodiments where the opening 12 is sealed in a liquid-tight manner by the receiving element 1 or a part of the receiving element 1 (e.g. by a part of the jacket surface 17), a closure is provided on the (part of the) receiving element 1 which terminates with the closure, cap 7 when the receiving element 1 is pushed into the closure cap 7. The closure can then overlap the closure cap 7 at both ends and latch into the same. The same principle of the closure can be applied when the opening 12, as described above, is sealed by a separate flap.

Additional seals can be provided to produce tightness between the flap or receiving element 1 on the one hand and closure cap 7 or its jacket surface 36 on the other hand.

FIG. 18 shows an axonometric view ox a partly exposed section of a schematically shown tablet 2, which can be arranged in a receiving element 1 in accordance with the invention. In the case of the embodiment of the tablet 2 which is shown in FIG. 18. It has a cylindrical snaps. This shape belongs to the variant of the embodiment of the receiving element 1 which is shown in FIG. 6. It can obviously also be considered to arrange the tablet 2 of FIG. 18 in the receiving element 1 of FIG. 3. On the other hand, the shape of the tablets 2 need not fundamentally correspond to the receiving volume 20.

One condition which needs to be fulfilled in any case is that a dispensing body volume 24 of the tablet 2 must not be greater than the receiving volume 20.

In order to keep the tablet 2 permanently in the dispensing body shape 22, the tablet 2 comprises a gauze 23 which is arranged on an exterior side 26 of the dispensing body.

FIG. 18 further shows that the dispensing body volume 21 is filled in sections by a plastic sponge 25. Balls 27 are also arranged in the dispensing body volume 21. The liquid 37 can advance through the plastic sponge 25 to the balls 27. The net-like fabric of the gauze 23 is also permeable to the liquid 37.

The balls 27 act as water-soluble elements in order to produce a beverage or release flavors and/or nutrients and/or dietary supplements and/or medical compounds, so that admixing to the liquid 37 can occur. For this purpose, the balls 27 are arranged according to the cross-sectional view according to FIG. 19. This means that each ball 27 has a surface 23 which is formed by a water-soluble icing layer 23, which is preferably made of sugar. The icing layer 28 delimits an interior 30 of the ball and has a specific icing layer thickness 31. The substance to be added to the liquid 37 is arranged in the interior 30 of the ball, especially flavors and/or nutrients and/or dietary supplements and/or medical compounds. In the embodiment of FIG. 19, the interior 30 of the ball is filled with syrup 32.

The release of the syrup 32 or its mixing with/addition to the liquid 37 only occurs when the icing layer 23 with the icing layer thickness 31 has been dissolved.

The icing layer thickness 31 can be provided with different thicknesses in different balls 27, so that the dissolution of the icing layer 28 takes different lengths in time. The time progression of the admixing of the syrup 32 can be arranged accordingly. Furthermore, the different balls 27 can contain different substances in their respective interiors 30 of the balls. Some balls 27 can therefore contain syrup 32, whereas other balls 27 provide other substances, e.g. to provide an isotonic beverage after a specific period of contact of the balls 27 with the liquid 37.

Furthermore, the balls 27 can be provided with different sizes, i.e. they can have differently large diameters as indicated in FIG. 18. In interaction with different icing layer thicknesses 31, it is thus possible to release different quantities of the substances situated in the interior 30 of the balls (e.g. syrups 32) depending on the duration of the contact of the balls 27 with the liquid 37.

It is finally also possible to arrange different substances (as explained, above, not necessarily syrups 32) in differently large balls 27 with different icing layer thicknesses 31. As a result, the time progression of the admixing of different quantities of different substances to the liquid 37 can thus be determined.
