Abstract:
A closure cap for mounting on a liquid container includes a preferably reclosable pouring opening and a receiving element which, with the closure cap, forms a common receiving volume for receiving at least one dispensing body, e.g. a tablet. The closure cap can be opened to create an access to the receiving volume and to be able to introduce the at least one dispensing body into the receiving volume or remove it from the latter, wherein the receiving element is permeable to a liquid in order to allow the dispensing body received therein to come into contact with the liquid. The access can be closed in a leaktight manner or opened by a closure element, which is connected to the closure cap and is movable by pivoting or sliding.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates to 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 comprises a spout opening, preferably a reclosable spout opening, and a receiving element, which together with the closure cap forms a common receiving volume for receiving at least one dispensing body, preferably at least one tablet, and the closure cap can be opened, thus forming an entrance to the receiving volume in order to enable the introduction of the at least one dispensing body into the receiving volume or the removal of said body from the receiving volume, 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. 
         [0002]    The present invention also relates to a dispensing body, preferably a tablet, for admixing to a liquid disposed in a liquid container having a closure cap in accordance with the invention. 
         [0003]    The present invention finally relates to a system, comprising a closure cap in accordance with the invention and at least one dispensing body in accordance with the invention. 
       DESCRIPTION OF THE PRIOR ART 
       [0004]    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. 
         [0005]    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. 
         [0006]    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. 
         [0007]    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. 
         [0008]    Incomplete dissolution of the tablet can be caused by sub-optimal dosing, especially an excessive concentration of the effervescent powder or tablets. Strictly speaking, 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. 
         [0009]    These disadvantages can be remedied at least in part according to US2010/0012193A1. 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 cart be dropped or lost. 
       OBJECT OF THE INVENTION 
       [0010]    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. One closure cap shall be provided for each of the few differently standardized types of threads, so that any number of different types of bottles can be used with few closure caps. It shall be ensured that during the insertion of a tablet no part of the closure cap or the closure cap itself can be dropped or lost. 
         [0011]    In particular, simple handling shall be guaranteed, which allows a simple exchange of the flavors and/or nutrients and/or dietary supplements. 
         [0012]    Furthermore, it shall be easy to remove partly dissolved dispensing bodies from the bottle with the closure cap for example. 
         [0013]    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 
       [0014]    These objects are 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 comprises a spout opening, preferably a reclosable spout opening, and a receiving element, which together with the closure cap forms a common receiving volume for receiving at least one dispensing body, preferably at least one tablet, and the closure cap can be opened, thus forming an entrance to the receiving volume in order to enable the introduction of at least one dispensing body into the receiving volume or the removal of said body from the receiving volume, 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. It is provided in accordance with the invention that a closure element connected to the closure cap is provided, by means of which the entrance can be sealed in a liquid-tight manner or released. 
         [0015]    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, the 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. 
         [0016]    It has been recognized that the closure element represents a simple and quick possibility to position a receiving body in the receiving volume or to remove it therefrom. The connection ensures that the closure element is unable to drop inadvertently. The user therefore will not have to worry where to place the closure element while the closure cap is open. Furthermore, the unpleasant situation that the closure element will drop on the floor and will thus become dirty can thus be prevented. The closure element can be arranged as the upper part of the closure cap for example which is simply folded away, or also as a door which is folded laterally. The various possibilities for configuration have in common that they offer simple and rapid access to the receiving volume and the dispensing body can thus be changed, introduced or removed in a rapid and simple way. 
         [0017]    The opening and especially the closing of the closure element can be provided in a simple and rapid manner without having to concentrate on the process. 
         [0018]    The receiving element is preferably formed as a flat surface. This represents an especially simple and thus inexpensive embodiment. 
         [0019]    In order to prevent that parts of the dispensing body seal the spout opening, the closure cap comprises a retention element which is arranged between the receiving element and the spout opening, wherein the retention element is permeable to a liquid in order to prevent the dispensing body from reaching the spout opening. The retention element can be arranged integrally with the closure cap, or it can be connected as a separate element to the closure cap. Permeability to liquids is provided in this case, which can be realized by small openings, so that the dispensing body or still unresolved parts thereof are prevented from blocking the spout opening. It is accordingly provided in a variant of the embodiment of the closure cap in accordance with the invention that the closure cap comprises a retention element which is arranged between the receiving element and the spout opening, wherein the retention element is permeable to a liquid in order to prevent the dispensing body from reaching the spout opening. 
         [0020]    A cost-effective production of the closure cap is achieved in a further preferred embodiment of the closure cap in accordance with the invention in that the receiving element is made of plastic. It can also be considered that the retention element is also made of plastic. 
         [0021]    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. 
         [0022]    The permeability of the retention element to the liquid is realized in a preferred embodiment of the closure cap in accordance with the invention such a way that the retention element comprises through-openings which are preferably formed 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. 
         [0023]    Potential contact of the dispensing body with the liquid already prior to drinking principally depends on the precise 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 twisting of the bottle, as performed by the user during the drinking process. It is thus accordingly provided in a preferred embodiment of the closure cap in accordance with the invention that the receiving element is arranged in the operating position in a volume formed by the closure cap. 
         [0024]    In order to enable the optional e-change of the receiving element, it is provided in a further preferred embodiment of the closure cap in accordance with the invention that the receiving element is releasably fastened in the closure cap. 
         [0025]    It is provided in a further embodiment of the closure cap in accordance with the invention that the retention element is releasably fastened in the closure cap. 
         [0026]    Slippage of the dispensing body can be prevented in that a circular boundary element which protrudes in the direction of the spout opening is arranged on the receiving element in order to prevent lateral slippage of the dispensing body in the operating state. Liquid thus flows evenly around the dispensing body from all sides. 
         [0027]    The closure element is pivotable in a further embodiment of the closure cap in accordance with the invention. It has been recognized that the pivotable closure element represents a simple and rapid possibility to position a tablet in the receiving volume or to remove it therefrom. The term pivotable shall be understood in such a way that the closure element can be detached from the closure cap and can thus can be removed at least in part to such an extent that the resulting opening allows access to the receiving volume in order to place a tablet in the receiving volume or to remove it therefrom. Pivotable therefore means that the closure element can be deflected from the position closing the entrance in order to introduce a dispensing body for example without the closure element dropping off, and can subsequently be brought back to the position closing the entrance in a simple way. 
         [0028]    In a further embodiment of the closure cap in accordance with the invention, the closure element is connected by means of a hinge-like connecting element. The hinge-like connecting element can be a thin web or one or several fixed hinges or a flexible plastic piece or any other suitable element. A hinge not only allows simple opening of the entrance to the receiving volume for example, but also offers a guide during closing which allows the user to avoid having to concentrate on the process of closing because the movement is guided by the hinges and it is merely necessary to apply an externally acting force in order to properly close the entrance. The user therefore need not take particular care how the entrance is closed, or that the user needs to position the closure element in a specific manner on the other part of the closure cap. 
         [0029]    In an embodiment of the closure cap in accordance with the invention, the closure element is formed as a part of the jacket surface of the closure cap, wherein it seals the entrance in the operating position. The closure element can be formed as a flap, which can be folded laterally, upwardly or downwardly. This represents a simple and elegant solution because it prevents the liquid from flowing out at the position of the closure element in the closed state of the closure element and offers access to the receiving volume in the open state in order to enable the rapid and simple positioning of a dispensing body, wherein unintended opening by specific situations is prevented. The closure cap can thus be provided with a reclosable mouthpiece, which is transferred from the closed state to the open state by a tensile force on the mouthpiece away from the closure cap. The force required for this purpose is calculated in such a way that the mouthpiece is not inadvertently opened by rubbing of other objects on the closure cap in a bag for example. This fact leads to the consequence however that closure elements opening in the upward direction can inadvertently be opened by said strong tensile force on the mouthpiece, which is prevented in the embodiment of the closure element as a part of the jacket surface. 
         [0030]    In a further embodiment of the closure cap in accordance with the invention, the closure cap comprises two parts, wherein the first part comprises the thread for fastening to a liquid container and the second part comprises the spout opening, and the second part forms the closure element. As a result of the two-part configuration, it is especially simple to position a dispensing body on the receiving element. 
         [0031]    It is possible that the transition from the first part to the second part represents a horizontal division of the closure cap. 
         [0032]    In an especially simple embodiment of the closure cap, the closure cap is formed cylindrically in the region of the transition. This represents a simple and thus also inexpensive embodiment. 
         [0033]    An especially simple and comfortable filling of the receiving volume can be realized in that the closure cap comprises an extractable storage element for the dispensing body, which storage element corresponds to the entrance and the receiving volume and which can be introduced through the open entrance into the receiving volume and can be positioned on the receiving element, which means the storage element is pulled from the open entrance for filling the receiving volume, at least one dispensing body is placed in the receiving element, and the storage element is thus pushed into the receiving volume again via the open entrance. It is further advantageous with respect to this embodiment that tablets which have already partly been dissolved in the receiving volume can be removed more easily again for example. 
         [0034]    In a further embodiment of the closure cap in accordance with the invention, the second part comprises on its jacket surface a local deformation facing inwardly in the radial direction of the closure cap, as a result of which a pressure is exerted in the operating position by the local deformation on the first part and the two parts are mutually clamped against each other. The deformation faces inwardly in the radial direction of the cylindrical receiving volume. It is thus prevented that the closure part is not additionally opened inadvertently in the case of closure caps with a mouthpiece which release the opening on the mouthpiece for drinking through a strong pull on the mouthpiece. 
         [0035]    A further embodiment of the closure element is that it is formed as a slide, which is displaceable along the jacket surface of the closure cap. The slide can be displaceable for example in the direction parallel to the longitudinal axis of the closure cap or normally to the longitudinal axis in the circumferential direction of the closure cap. The slide can substantially correspond to a rectangular section from the jacket surface of the closure cap. 
         [0036]    It can be provided in the configuration of the closure element as a slide that the slide is displaceable in relation to the closure cap by using a profile rail. One or several profile rails can thus be provided in the slide on opposite sides (e.g. on or close to longitudinal edges or transverse edges, per side, which profile rails extend in parallel with respect to each other and are guided in depressions of the closure cap with a respective profile. It can conversely be provided that the closure cap comprises at least two profile rails which are parallel with respect to each other outside of the entrance, which profile rails engage in the respective depressions of the closure element. The profile of the profile rail comprises a taper for example in both cases, so that the profile rail cannot be pulled out of the depression normally to its longitudinal extension. 
         [0037]    A dispensing body, preferably a tablet, is provided in accordance with the invention for accommodation 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. 
         [0038]    Accordingly, the use of a dispensing body, preferably a tablet, in a receiving volume of a closure cap in accordance with the invention is provided according to the invention. 
         [0039]    In order to ensure that the dispensing body can be accommodated in a receiving volume, it is provided in a preferred embodiment of the dispensing body in accordance with the invention that the dispensing body has a dispensing body volume which is not greater than the receiving volume. 
         [0040]    In order to enable producing a beverage when making contact with liquid or to release flavors and/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 comprises 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. 
         [0041]    If at least one dispensing body is arranged in the receiving volume, the liquid flows around said body during the drinking process and it is able to release substances, especially flavors and/or nutrients and/or dietary supplements and/or medical compounds to the liquid, which means mixing with the liquid occurs directly before the user actually drinks the mixture. An excessive concentration of the desired substances in the liquid can thus principally be avoided. 
         [0042]    Notice must be taken in this respect that after removing the bottle after the drinking process a specific portion of the liquid will generally flow back into the bottle from the receiving volume. A specific proportion of the aforementioned substances can be transferred to the remaining liquid situated in the bottle, which needs to be considered in the configuration of the dispensing body or its dispensing characteristics. 
         [0043]    In order to ensure a spatially stable arrangement of the water-soluble elements, which additionally contributes to ensuring that no water-soluble elements can pass through the passage openings of the closure cap, they are arranged in a sponge for example which fills the dispensing body volume at least in part. It is therefore accordingly provided in a preferred embodiment of the dispensing body in accordance with the invention that the dispensing body therefore comprises a sponge, preferably a plastic sponge. Said plastic sponge can be formed in an especially preferred manner 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. 
         [0044]    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 gauze, which retains the dispensing body in a dispensing body shape which fits into a receiving volume. The thus stabilized dispensing body shape especially also allows simple and convenient changing of the dispensing body even after the drinking process, once the water-soluble elements have already been dissolved entirely or at least partly. 
         [0045]    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. 
         [0046]    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. 
         [0047]    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. 
         [0048]    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. 
         [0049]    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 comprise different layer thicknesses, especially in order to enable continuous delivery of the substance or substances. 
         [0050]    Finally, the closure cap in accordance with the invention and the liquid container shall be regarded as a system which allows simple production of beverages or the admixture of flavors and/or nutrients and/or dietary supplements and/or medical compounds to a liquid.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0075]      FIG. 1  shows a liquid container in form of a bottle  5 , having a base body  36  and a closure cap  7  in accordance with the invention. The closure cap  7  is shown in an operating position  8 , in which the closure cap  7  seals a spout opening  9 . The closure cap  7  is screwed onto the base body  36  by means of a thread  34  (see  FIG. 2 ). 
         [0076]    The closure cap  7  is provided with a mouthpiece  33 , which is shown in  FIG. 1  in the closed position  11 . In the closed position  11 , the closure cap  7  is impermeable to a liquid  37 , which is accommodated in the bottle  5  or in the base body  36  of the bottle and has a liquid level  38 . The mouthpiece  33  can be brought from the closed position  11  to a release position (not shown) by displacing the mouthpiece  33  along a longitudinal axis  10 . 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 . 
         [0077]    The base body  36  of the bottle comprises inner walls  6  which together with the closure cap  7  delimit a volume  4  in the operating position  8 . A receiving element  1  of the closure cap is arranged in accordance with the invention in said volume  4 , which receiving element forms a joint receiving volume  20  together with the closure cap  7  for accommodating at least one dispensing body  2 , preferably at least one tablet.  FIG. 2  illustrates such an embodiment on the basis of an axonometric view of a closure cap shown with an exposed section. 
         [0078]    The receiving element  1  is fastened to the closure cap  7 , preferably releasably attached thereto, and is formed as a flat surface. The receiving element  1  is thus arranged in a volume formed by the closure cap  7  in the operating position  8 . The receiving element  1  makes contact with the inner wall of the closure cap  7  at least in all points of a circular orbit. The tablets  2  (see  FIG. 14 ) can be positioned on the receiving element  1 . A circular boundary element  16  ( FIG. 2 ) prevents lateral slippage of the tablet, which is contacted by the liquid  37  accommodated by 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 dispensed to the liquid. 
         [0079]    The closure cap comprises an entrance  12  in order to enable the insertion of the at least one tablet  2  into the receiving volume  20  or the removal of said tablet from the receiving volume  20 . In the embodiment shown in  FIGS. 1 and 2 , the closure cap  7  comprises a first bottom part  13  which comprises the receiving element  1 , and a second upper part  14  which comprises the spout opening  9  and a retention element  41 , wherein a transition  46  of the second part  14  to the first part  13  is representative of a horizontal division.  FIG. 3  shows this embodiment in the open state. 
         [0080]    The transition  46  divides the closure cap  7  into the first part  13  and the second part  14  in  FIG. 1 . The retention element  41  is situated in the second part  14 . It is arranged as a flat surface in the illustrated embodiment, as also the receiving element  1 . 
         [0081]    A bulge  18  is arranged in the region of an edge  39  of the first part of the closure cap, which bulge extends along the full circumference of the closure cap  7 . A notch  19  is arranged in the region of an edge  40  of the second part of the closure cap, which notch also extends in a closed circular manner along the second part  14  of the closure cap on its inner side. The innermost measured circumference of the notch  19  is greater by one-tenth of a millimeter than the outermost circumference of the bulge  18 , so that the two parts  13  and  14  tightly seal the closure cap in the operating position  8 . 
         [0082]    A hinge-like connecting element  43  also connects the two parts  13  and  14  of the closure cap  7  in the open state. The connecting element  43  allows the second part  14  to be folded up from the rest. 
         [0083]    The second part  14  has a local deformation  47  on its jacket surface. The deformation  47  is under tension in the closed state (comparison between deformation in the relaxed state/tensioned state shown in  FIGS. 4 and 5 ), thus preventing the inadvertent opening of the two parts  13  and  14 . Furthermore, the bulge  18  prevents the inadvertent opening in that the deformation  47  needs to be pushed over the bulge  18  during the opening of the closure element  42 , thus producing a resistance. 
         [0084]    Both the receiving element  1  and also the retention element  41  comprise through-openings  15 , through which the liquid  37  enters into or exits from the receiving volume  20  at least during the drinking process and thus comes into contact with the tablets  2  situated in the receiving volume  20 . As can be recognized in  FIG. 2 , the through-openings are arranged in regular intervals, thus producing a grid or lattice shape. The through-openings  15  allow the production of a beverage or the dispensing of substances, especially flavors and/nutrients and/or dietary supplements and/or medical compounds, from the tablets  2  to the liquid  37 . 
         [0085]      FIGS. 10 to 13  show alternative embodiments of the closure cap  7  in accordance with the invention, which can be screwed onto all standardized water bottles, especially PET bottles, by means of the thread  34 . A closure cap according to the prior art is shown in  FIG. 9  for comparison purposes. In order to help the user to unscrew and remove the closure cap  7 , the closure caps  7  shown in  FIGS. 10 to 13  have a surface structure  35  which is arranged in this case as fluting. Furthermore, the closure cap  7  comprises a cover  3  which is removable or can be folded away, by means of which the mouthpiece  33  (as shown in the drawings) can be covered. 
         [0086]      FIG. 12  shows an axonometric view of the closure cap  7  of  FIG. 10  with a partly exposed section and with a receiving element  1  in accordance with the invention and a retention element  41 . The receiving volume  20  has a cylindrical shape. 
         [0087]    An alternative embodiment is shown in  FIGS. 6 to 8 . The closure cap  7  comprises a closure element  42 . In the closed state, which is shown in  FIG. 6 , it entirely seals the entrance  12 , so that no liquid  37  can escape. In the open state  17  (shown in  FIG. 7 ), the closure element  42  releases the entrance  12  and thus allows inserting a tablet  2  into the receiving volume  20  or removing said tablet from said volume. In this process (see  FIG. 8 ), the receiving element  1  is situated on the side of the closure element  42  facing the thread  34 , while the retention element  41  is situated on the side of the closure element  42  which faces the mouthpiece  33 . 
         [0088]      FIG. 14  shows an axonometric view of a schematically shown tablet  2  which is shown with a partly exposed section and which can be arranged in a receiving volume  20 . In the case of the embodiment of tablet  2  which is shown in  FIG. 14 , it comprises a dispensing body shape  22  which fits into 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 . 
         [0089]    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. 
         [0090]      FIG. 14  further shows that the dispensing body volume  24  is filled in sections by a plastic sponge  25 . Balls  27  are also arranged in the dispensing body volume  24 . 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 . 
         [0091]    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 of  FIG. 15 . This means that each ball  27  has a surface  29  which is formed by a water-soluble icing layer  28 , 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. 15 , the interior  30  of the ball is filled with syrup  32 . 
         [0092]    The release of the syrup  32  or its mixing with/addition to the liquid  37  only occurs when the icing layer  28  with the icing layer thickness  31  has been dissolved. 
         [0093]    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 . 
         [0094]    Furthermore, the balls  27  can be provided with different sizes themselves, i.e. they can have differently large diameters as indicated in  FIG. 14 . 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 . 
         [0095]    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. 
         [0096]      FIG. 16  shows a further embodiment of a closure cap in accordance with the invention, where the closure cap  42  is formed as a slide which is displaceable along the jacket surface of the closure cap, namely downwardly from the closing position (away from the cover  3 ) to the open position. For this purpose, straight profile rails are provided on the inner side of the closure elements  42  close to the longitudinal edges, which profile rails engage in respective straight depressions  48  of the closure cap  7  which extend in parallel to the longitudinal axis  10 . In all other respects, the configuration of the closure cap  7  is substantially identical to that of  FIG. 13 , namely with respect to the receiving element  1 , the cover  3 , the retention element  41  (not shown in  FIG. 16 ), the thread  34  and the surface structure  35 . 
         [0097]    Mutually corresponding seals (not shown here) are provided on the transverse edges (extension in the circumferential direction of the closure cap  7 ) of the closure element  42  and on the transverse edges of the entrance  12 , e.g. by means of sealing bulges on one part and respective depressions on the other part. 
         [0098]    The embodiment according to  FIG. 17  substantially corresponds to that of  FIG. 16 , but in this case the closure element  42  which is arranged as a slide is not displaceable along the longitudinal axis  10 , but along the circumference of the closure cap  7 . Annular profile rails are accordingly provided on the inner side of the closure element  42  close to the two transverse edges, which profile rails engage in respective annular depressions  48  of the closure cap  7 , which depressions extend normally to the longitudinal axis  10 , namely in the circumferential direction. 
         [0099]    The embodiment according to  FIG. 18  is very similar to that of  FIG. 16 , but the closure element  42  which is arranged in  FIG. 18  as a slide is only upwardly displaceable from the closing position. The closure element rests on a stop of the closure cap  7  on the bottom side. The closure element  42  can thus not be pushed downwardly out of the depression  48  as a result of gravity or incorrect actuation and be separated from the closure cap  7 . In order to prevent the closure element  42  from being pushed out in the upward direction, a protrusion could be provided on the bottom side of the closure element  42  which upon reaching the uppermost (open) position of the closure element  42  is retained by a respective element of the closure cap  7 . 
         [0100]    The closure cap  42  comprises on its inner side (=the side facing the closure cap) a respective profile rail  44  on the two longitudinal edges, which are guided in respective depressions  48  (grooves) of the closure cap  7 . The profile of the profile rail  44  has a respective tapering portion in this case, which is engaged around by the profile rail  44 , especially in an interlocking manner, so that the profile rail  44  cannot be pulled out of the depression  48  in the normal direction to its longitudinal extension. The longitudinal edges of the closure element  42  in  FIG. 16  and the transverse edges of the closure element  42  in  FIG. 17  could be guided and sealed similarly. 
         [0101]    Since the depressions  48  are inwardly offset away from the jacket surface of the closure cap  7 , the outside surface of the closure element  42  can be flush with the jacket surface. 
         [0102]    The profile rails  44  and the depressions  48  seal the entrance  12  in a liquid-tight manner on the longitudinal edges of the closure element  42 . It is shown in  FIG. 22  that the upper transverse edge of the closure element  42  is sealed by means of a sealing bulge  49  which is arranged on the closure cap  7 , extends in the circumferential direction and engages (especially in an interlocking manner) in a respective recess on the upper transverse edge of the closure element  42 . The bottom transverse edge of the closure element  42  is sealed in the same way. The transverse edges of the closure element  42  in  FIG. 16  and the longitudinal edges of the closure element  42  in  FIG. 17  could be sealed in a similar way. 
         [0103]    Limit stops or the like can be provided in all embodiments of  FIGS. 16 to 23  in order to prevent the downward sliding off the closure element  42  from the closure cap. 
         [0104]    In the embodiment according to  FIGS. 18 to 23 , the receiving element  1  and the retention element  41  are formed in an integral manner with the closure cap  7  and are made of plastic. 
         [0105]    It would principally be possible in all embodiments of  FIGS. 1 to 13 and 16 to 23  that the dispensing body is not placed directly through the entrance  12  in the receiving volume  20 , but is placed in a removable (e.g. extractable, similar to a drawer) storage element which is introduced through the entrance  12  into the receiving volume  20  and can also be removed therefrom again. The storage element can come to lie in the receiving element  1  or can also replace said element.
