current technology

In order to be able to remove liquids on the road or while exercising, drinking bottles are known, in particular drinking bottles with locking caps. Drinking bottles usually have a thread onto which the locking cap is screwed. Here, the threads are standardized and the number of different standardized threads of the drinking bottle is small. On the one hand these bottles can be prefilled, for example, with mineral water, which can also be mixed with flavored or isotonic beverages. On the other hand, it can be a bottle which is intended to contain liquids which are mixed together by the user at will. In this case, in addition to fruit syrups, in particular effervescents in powder or tablet form are used.

The disadvantage in both cases is that the user is unable to act on the specific beverage mixture over the entire duration of consumption of the beverage, that is to say between the beginning and the end of consumption of the beverage. That is to say, the user can no longer change the flavor during the consumption of the beverage, since the liquid still present in the bottle only has the once selected flavor.

It's not just taste desires that may change between the start and end of beverage consumption. If the user, for example, has decided to use a non-isotonic drink and wants to drink an isotonic drink after he has been exercising for a certain period of time, for example, this is likewise no longer possible with the liquid still present in the bottle.

Furthermore, the use of chemicals for dissolving the effervescent tablet is required when preparing beverages by means of the effervescent tablet. That is to say, here it is not possible to use purely natural substances for the preparation of beverages, which can be seen as a disadvantage.

Furthermore, it can happen not only in effervescent powders but also in effervescent tablets: the powder or tablet does not dissolve completely and parts of the powder or tablet reach the user's mouth, which can be uncomfortable.

Incomplete dissolution may also be associated with a sub-optimal choice of dosing, especially with high concentrations of powders or tablets. However maintaining the correct dosing is usually not always easy to do, since strictly speaking when the powder or tablet is mixed with a liquid (normally water) the specific amount of liquid present must be taken into account.

These disadvantages can be overcome at least in part according to US2010/0012193A1. This patent document describes a liquid container comprising a closure cap which is implemented in three parts: a tablet container, a container cap and a closure cap closure. In order to insert the tablet into the tablet container, the container cap must be unscrewed and then screwed on again. A disadvantage is the fact that the container lid can fall off or get lost here.

Purpose of the invention

The object of the present invention is to provide a closure cap for a liquid container which allows flavors and/or nutrients and/or food additives and/or medically active Liquid mixing in liquid container. In particular, a simple operation is to be ensured, which allows easy replacement of flavorings and/or nutritional ingredients and/or food additives. Furthermore, dosing problems, in particular excessively high concentrations of flavors and/or nutritional ingredients and/or food additives in the liquid, should be avoided. Here, too, the possibility of avoiding chemicals should be provided, so that it can be used to mix purely natural substances.

Description of the invention

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

- a preferably reclosable outlet opening,

- a receiving element for accommodating at least one feeding body, preferably at least one tablet, wherein the receiving element is permeable for a liquid, so that the at least one feeding body can be brought into contact with the liquid,

- an opening so that the at least one feed body can be introduced into or removed from the receiving volume by means of the receiving element.

It is provided here that the receiving element is actuatable in the operating position of the closure cover and can pass through the opening both from the receiving volume into the loading position for changing the feed body and into the receiving volume into the feeding position.

This makes it possible to replace the feeding body without having to separate the closure cap from the liquid container. The receiving element is thus actuatable laterally of the closure cover, for example in a direction perpendicular to the longitudinal axis of the closure cover. The opening is likewise on the side of the closure cover. In the loading position, the opening for introducing the feed body is open, the receiving element is at least partially separated from the holding volume, so that the feed body on or in the receiving element can be removed and/or the feed body can be placed on or into an empty receiving element (or generally replace the receiving element). In the feed position, the opening for introducing the feed body is blocked, and the liquid flowing from the liquid container into the fastened locking cap can then only exit through the discharge opening or through the fastened mouth. The latch cap is ejected. Thus, the opening for introducing or removing the feed body is then closed liquid-tight.

A liquid container, particularly preferably embodied as a PET bottle, which is closed with the closure cap according to the invention has a conventional outlet opening or bottle opening which is closed by the closure cap in the operating position. The closure cap is preferably a screw closure cap which fits all standardized water bottles, or a small number of different standardized bottle thread types with a small number of different closure caps can be used. The closure cap is usually provided with a mouth which closes the outlet opening of the closure cap and which can be transferred from the closure position into the release position, preferably by moving the mouth. In the closed position, no liquid can escape through the closed cap through the mouth. Thus, in the working position, with the locking lid according to the invention, a secure storage of the liquid in the liquid container can be achieved, even if the liquid container is transported or carried by the user during movement. In the release position, liquid can be passed through the closure cap via the mouth and drinking by the user can be achieved.

The receiving element is arranged and detachably fastened in the feeding position within a receiving volume which is delimited in addition to the walls of the receiving element by the inner wall of the closure cover. This arrangement allows the liquid to flow through the receiving element primarily during drinking when the liquid container is delivered to the user's mouth. If at least one feed body is provided in the receiving element, the feed body is circulated by the liquid when drinking and can dispense materials or substances, in particular flavors and/or nutritional ingredients and/or food additives and/or medicinal The active ingredient is fed into the liquid. That is, direct mixing with the liquid occurs before the user actually drinks the mixture. In principle, too high a concentration of the desired material in the liquid can thus be avoided.

To this end, it should be noted that when the liquid container (bottle) is set down after the drinking process, usually a certain part of the liquid flows back from the receiving element into the liquid container. In this case, a certain proportion of the aforementioned materials or substances may be transferred to the remaining liquid in the liquid container, which must be taken into account when designing the feed body or its feed properties.

In order to prevent the feed body from falling out of the holding volume, the holding volume is preferably surrounded on all sides, regardless of the specific shape of the holding volume. A permeability for liquids is proposed here, which can be achieved, for example, by means of small openings, whereby however an all-round enclosure of the receiving volume is present. This complete enclosing of the receiving volume can be provided by the receiving element itself or by the interaction of the receiving element with another part of the closure cover.

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 liquids is achieved in a preferred embodiment of the liquid container according to the invention in that the receiving element has passage openings which are preferably arranged in a grid-like or grid-like manner. . In this way, it is also reliably avoided that the feed body or parts of the feed body get into the liquid container after drinking.

The possible contact of the feeding body with the liquid already before drinking is in principle dependent on the arrangement of the receiving element in the closure cap. Contacts can be avoided in vertically placed liquid containers if the receiving element is located entirely in the volume formed by the closure lid. This refers to a volume which is delimited on one side by the closure cover and on the other side by an imaginary surface which is itself delimited by the edge of the closure cover. This imaginary surface is practically free of material so that the closure cap can be connected, preferably screwed, to the liquid container. This means that contact in this case is only achieved when the bottle is turned over, eg by the user while drinking. Accordingly, in a preferred embodiment of the liquid container according to the invention it is provided that the entire receiving element is arranged in the feeding position in the volume formed by the closure lid.

In order that the receiving element does not fall out of the closure cap in the filling position and is not lost or soiled, in another preferred embodiment of the liquid container according to the invention it is provided that the receiving element is fastened, preferably releasably fastened. Fastened to the latching cover. If the receiving element can be pulled out of the closure lid, for example like a drawer, a safety device can be provided which prevents it from being pulled out completely during normal use and which can be removed by certain measures, for example for cleaning the receiving element. One embodiment of the invention provides that the opening (so that the at least one feed body can be introduced into or removed from the receiving volume) can be closed liquid-tight by the receiving element in the operating position of the closing cover. In this case, therefore, no separate closure is required for the opening, the receiving element itself serves as a closure for the opening. In the feeding position of the receiving element, in particular the liquid-tight region of the receiving element can form part of the peripheral surface of the closure cover, so that the closure cover and the externally visible surfaces of the receiving element merge seamlessly into one another. As a result, the receiving element and the closure cover form a common outer surface, without protrusions or recesses where dirt can collect.

However, it is of course also possible for the opening to be closed by a cover or slide fastened on the locking cover as soon as the receiving element has been brought into the feeding position.

The actuation of the receiving element can advantageously be designed in such a way that the receiving element is displaceable, in particular linearly displaceable, relative to the closure cover. As a result, the receiving element can be pulled out of or pushed into the closure cover similar to a drawer. The direction of movement can in particular be perpendicular to the longitudinal axis of the closure cap (=axis of rotation in substantially rotationally symmetrical closure caps or equivalent to the axis of rotation of the bottle on which the closure cap is fastened or the direction of liquid entry into the closure cap). Corresponding guides for the translational movement, such as recesses (grooves) or projections, can be provided on the inner side of the closure cover.

As an alternative thereto, the receiving element can be rotatable relative to the closure cover, in particular about an axis parallel to the longitudinal axis of the closure cover.

A combination of translational and rotational movements of the receiving element is also conceivable when it is pushed into or pulled out of the closure cover.

A particularly simple and convenient filling of the receiving element can be achieved in that the receiving element is designed like a drawer, which can be pushed from the outside into a corresponding opening of the closure cover and can also be pulled out of the corresponding opening again. That is to say, to fill the receiving element, the receiving element is pulled out of the corresponding opening, at least one feeding body is inserted into the receiving element, and the receiving element is then pushed back into the corresponding opening. A receiving element is therefore preferably provided which has a bottom surface and a peripheral surface (however without a covering surface which closes off the receiving element), wherein a passage opening is provided on the bottom surface. A further element comprising a passage opening for the liquid is then provided between the receiving element and the outlet opening of the locking cap, so that the feed body or parts thereof do not reach the mouth. In order to facilitate the handling (pull out and push in; and/or pivot) of the receiving element, corresponding auxiliary devices can also be provided on the peripheral surface of the receiving element.

In order to achieve a simple and thus cost-effective production of the container in this case, provision is made in another preferred embodiment for the auxiliary device to comprise recesses and/or protrusions on the peripheral surface. The recess or protrusion enables the container to be easily grasped by the user.

The receiving element can be produced and sold as a unit with the feed body contained therein if the receiving element has a cover surface with a passage opening so that the receiving volume is completely surrounded by the peripheral surface, the cover surface and the bottom surface. In this case, the peripheral surface, the cover surface and the bottom surface can be non-detachably connected to one another, so that the unit forms a disposable product which is replaced after use by a new unit consisting of the receiving element and the feed body.

In order to ensure simple handling and optimized dosing possibilities when using the closure cap according to the invention, a feed body, preferably a tablet, is provided according to the invention for being accommodated in the receiving element of the closure cap according to the invention middle.

Accordingly, the invention provides for the use of a feed body, preferably a tablet, in the receiving element of the closure cap according to the invention.

In order to be able to produce a drink or to release flavors and/or nutritional ingredients and/or food additives and/or medicinally active ingredients on contact with a liquid and thereby to be able to mix it with a liquid, a preferred embodiment of the feed body according to the invention One embodiment provides that the feed body has at least one water-soluble element for producing a beverage and/or for releasing flavor and/or nutritional and/or food additives and/or medicinally active ingredients. Nutrients here include hydrocarbons, minerals and vitamins. If many hydrocarbons, minerals and vitamins are released, isotonic drinks can thus be produced.

In order to accommodate the feed body in the accommodation volume of the accommodation element, the volume of the feed body is not greater than the accommodation volume of the accommodation element. In particular, the feed body has dimensions that enable pushing through the opening for the receiving element. In other words, it must be provided that the maximum cross section of the feed body is smaller than the cross section of the opening of the closure cover through which the receiving element can enter the filling or feeding position.

In order to ensure a spatially stable arrangement of the water-soluble element (which additionally contributes to the fact that no water-soluble element can pass through the passage opening of the receiving element), the water-soluble element is arranged in the sponge, so The sponge at least partially fills the feed volume. Accordingly, provision is made in a preferred embodiment of the feed body according to the invention that the feed body comprises a sponge, preferably a plastic sponge. The plastic sponge is particularly preferably designed such that liquid can reach the water-soluble element without problems, which can be achieved, for example, by a sponge fabric made of coarsely knitted fibers.

In order to further improve handling, it is provided in a preferred embodiment of the feed body according to the invention that the feed body has a liquid-permeable net-like fabric, in particular a mesh, which holds the feed body in the In the shape of the feed body, the shape of the feed body preferably corresponds to the shape of the containment volume of the containment element. The thus stabilized shape of the feed body also allows, in particular, a simple and convenient replacement of the feed body after drinking, since the water-soluble element has been completely or at least partially dissolved. An embodiment in which the shape of the feed body corresponds to the shape of the receiving volume of the receiving element also ensures a particularly stable arrangement of the feeding body in the receiving element or its receiving volume.

A particularly good stability of the shape of the feed body can be achieved at the same time as simple manufacturability in that the net-like fabric is arranged on the outside of the feed body.

In order to avoid the use of chemicals and to use only natural substances for beverage preparation, it is provided in a preferred embodiment of the feed body according to the invention that the at least one water-soluble element is a spherical body, the surface of which is formed by a water-soluble layer and the inside of which is filled with a substance, such as syrup or tea, which contains flavorings and/or nutritional ingredients and/or food additives and/or medicinal Active ingredients. The water-soluble layer is preferably formed here from a water-soluble glaze, especially a sugar coating, which helps to avoid chemicals.

The time course of the feed of the substances, in particular flavors and/or nutritional ingredients and/or food additives and/or medicinally active ingredients, can be achieved by a plurality of spheres with different glaze layer thicknesses. The spheroids with the thinnest glaze thickness released the substance first, while the spheroids with the thicker glaze thickness did not release the substance yet. Only at a later moment, for example, when the substance of those spheres with an initially thin enamel thickness is consumed, the spheres with an initially thicker enamel thickness release the substance stored therein.

Here, for example, the same substances as before can be involved, so that a time-invariant concentration of these substances in the liquid is achieved. However, it is also possible for different substances to be present in the spheroid, so that, for example, a fruity beverage is provided first and an isotonic beverage is provided at a later time. The athlete can drink different beverages over time while carrying a single liquid container, wherein isotonic beverages are also included here.

Therefore, in a particularly preferred embodiment of the feed body according to the invention it is provided that a plurality of spherical bodies with the same substance or different substances are arranged in the feed body volume, wherein the water-soluble layer of the spherical bodies There are different layer thicknesses, in particular in order to enable a continuous feed of the substance or substances.

Finally, the liquid container according to the invention and the feed body according to the invention can be regarded as a system which enables the simple production of beverages or the addition of flavors and/or nutritional ingredients and/or food additives and/or medicinally active ingredients Mix into liquid.

Modes of Carrying Out the Invention

FIG. 1 shows a liquid container in the form of a bottle 5 comprising a latching cap 7 . The closing cap 7 is shown in an operating position 8 in which it closes the outlet opening 9 of the bottle 5 . The closure cap 7 is here screwed onto the bottle 5 by means of a thread 34 (see FIG. 2 ). A surface structure 35 in the form of indentations (see FIG. 4 ), which is not shown here, makes it easier for the user to fasten the closure cap 7 on the bottle 5 .

The closure cover 7 is provided with a mouth 33 , which is shown in the closed position 11 in FIG. 1 . In the closed position 11 , the closed cap 7 is impervious to the liquid 37 contained in the bottle 5 and having a liquid level 38 . By displacing the mouth 33 along the longitudinal axis 10 (see FIG. 2 ), it is possible to move the mouth 33 from the blocking position 11 into a release position (not shown). In this release position, the closure cap 7 is permeable for liquid 37 to enable the user to drink from the bottle 5 .

The bottle 5 has a bottle inner wall 6 which, together with the closure cap 7 , delimits the volume 4 in the operating position 8 . According to the invention, a receiving element 1 is provided in this volume 4 , which can be pushed into a closure cover 7 . FIG. 2 illustrates such an embodiment with the aid of a cutaway three-dimensional view of the closure cover 7 , and FIG. 3 shows the associated receiving element 1 pulled out of the closure cover 7 . The receiving element 1 here has a receiving volume 20 , wherein the receiving volume has an approximately cylindrical shape. The receiving element 1 is shown here only schematically and is described in more detail below.

The receiving volume 20 enables receiving at least one feed body, preferably at least one tablet 2 (cf. FIG. 18 ), which feed body/tablet can be contacted by the liquid 37 contained in the bottle 5 especially during the drinking process. A beverage can thereby be produced or substances such as flavorings and/or nutritional ingredients and/or food additives and/or medicinally active ingredients can be fed to the liquid.

In the case shown, the receiving element 1 comprises a bottom surface 16 and a peripheral surface 17 which surrounds the bottom surface 16 . The bottom surface 16 has passage openings 15 which can be formed, for example, by a grid. The receiving element 1 has no covering surface, ie is open upwards, so that the tablets 2 can be easily inserted from above. In order that the tablet 2 or parts thereof cannot leave the receiving volume 20 upwards to the mouth 33, in the closure cover 7 between the receiving element 1 (in the closed filling position) and the discharge opening 9 (or the mouth 33) a A further element 13 towards the bottom 16 has a passage opening 15 for liquid. The further element 13 is arranged here directly above the receiving element 1 , so that the receiving volume 20 is completely enclosed and corresponds to the free volume in the receiving element 1 .

The bottom element 16 and the further element 13 are here planar and arranged parallel to each other.

Via the bottom surface 16 and the passage opening 15 of the element 13 , liquid 37 can enter the receiving volume 20 at least during drinking and thus come into contact with the tablet 2 present in the receiving volume 20 . As can be seen in FIGS. 2 and 3 , the openings 15 are arranged regularly, thereby forming a grid or grid. The production of a beverage or the feeding of substances of the tablet 2 , in particular flavors and/or nutritional and/or food additives and/or medicinally active ingredients, to the liquid 37 can be achieved via the opening 15 .

In order that the receiving element 1 can assume the feeding position precisely, guides, such as grooves 14 in this case, are provided on the housing inner side of the closure cover 7 . Auxiliary means 18 , ie protrusions 19 , are used for manipulating the receiving element 1 .

FIG. 4 shows an alternative embodiment of a closure cap 7 which can be screwed onto all standardized water bottles, in particular PET bottles, by means of a thread 34 . In order to make it easier for the user to screw on and off the closure cap 7 , the closure cap 7 shown in FIG. 4 has a surface structure 35 which in this case is embodied as a corrugation. Furthermore, the closure lid 7 of FIG. 4 has a removable or foldable cover 3 , by means of which the mouth 33 can be covered as shown in FIG. 5 .

FIG. 5 shows a cutaway triaxial view of the closure cover 7 from FIG. 4 with the associated receiving element 1 pulled out and shown in FIG. 6 .

Compared to the variant shown in FIGS. 1 to 3 , the closure cover 7 in FIGS. 4 to 6 has a greater extension along the longitudinal axis 10 . This provides more space for the opening 12 , which is embodied in its dimensions and in its shape corresponding to the receiving element 1 or the receiving volume 20 shown in FIG. 6 .

In both embodiments, the receiving element 1 is entirely contained in a volume formed solely by the closure cover 7 . This is the volume that is delimited on one side by the closure cover 7 and on the other side by an imaginary surface that is in turn delimited by the edge 40 of the closure cover 7 . This imaginary surface is practically free of material, so that the closure cap 7 can be connected to the bottle 5 (see FIG. 1 ), preferably by screwing it on with the thread 34 .

The receiving element 1 of FIG. 6 has an approximately cylindrical design and again has a bottom surface 16 and a peripheral surface 17 . The receiving element 1 can thus again be pushed like a drawer into the corresponding opening 12 of the closure cover 7 or pulled out of the opening 12 even when the closure cover 7 is in the working position. If the closing cover 7 is in the operating position 8 , the receiving element 1 is introduced in this way into or out of the closing cover 7 through the corresponding opening 12 . Accordingly, the user does not have to unscrew the closure cap 7 from the bottle 5 in order to fill the receiving element 1 with the tablets 2 . When the receiving element 1 is pushed into the corresponding opening 12 of the closure cover 7 , the bottom surface 16 faces away from the mouth 33 . The receiving element 1 is shown here only schematically and is described in more detail below.

A here circular element 13 with a passage opening 15 , which closes the receiving volume 20 , is arranged directly above the inserted receiving element 1 .

The receiving element 1 in FIG. 6 can also have a removable (for example foldable) cover surface provided with the opening 15 , so that the receiving volume 20 is completely surrounded by the receiving element 1 itself. The element 13 can then be dispensed with.

The receiving element 1 for the embodiments according to FIGS. 4 to 6 can also be embodied as in FIG. 17 , where the receiving volume 20 is completely surrounded by the receiving element 1 itself, ie by a cylindrical peripheral surface impermeable to liquids. 17. Surrounded by a liquid-permeable bottom surface 16 and a cover surface 21 . Here again, the element 13 in the closure cover 7 can be dispensed with on the basis of the cover surface 21 . During production, the feed body 2 can be inserted into the receiving element 1 according to FIG. 17 before locking and the receiving element 1 can then be locked in a non-detachable manner. When a feed body 2 is consumed or another feed body is required, another feed body 1 with another (eg unconsumed) feed body 2 is inserted.

In order to be able to easily push the receiving element 1 into the opening 12 or pull it out of the opening 12, the receiving element shown in FIG. The receiving element 1 acts on the protrusion. Of course, the auxiliary device 18 can also have further elements, for example recesses (not shown) in the peripheral surface 17 .

In order not to impair the tightness of the closure cap 7 when inserting the receiving element 1 , no passage opening 15 is provided in the peripheral surface 17 , but only in the bottom surface 16 .

FIG. 7 again shows a closure cover 7 of the same type as in FIG. 4 . In the region of the receiving element 1 , the closure cover 7 is of cylindrical design. However, in FIG. 7 there is a receiving element 1 which closes the opening 12 liquid-tight in the feed position with its peripheral surface 17, which is here a part of the cylindrical jacket, as can be seen in FIG. as seen. The peripheral surface 17 thus forms part of the peripheral surface 36 of the closure cover 7 .

The receiving element 1 corresponding to FIG. 7 can comprise, as in FIG. 9 , a semicylindrical peripheral surface 17 , a liquid-permeable bottom surface 16 and a liquid-permeable cover surface 21 , wherein the bottom surface 16 and the cover surface 21 are connected. To the peripheral surface 17 of the receiving element 1 and to the peripheral surface 36 in the feeding position when the receiving element 1 has been pushed completely into the closure cover 7 . By this, the feed body (tablet) 2 in the receiving volume 20 is completely contained in this receiving element, the entire feed body 2 or parts thereof cannot reach the mouth 33, which is covered here by the cover. 3 cover.

As an alternative to FIG. 9 , the receiving element 1 in FIG. 7 can also be formed without cover surface 21 , as shown in FIG. 10 . However, a further element 13 with a passage opening must be arranged in the closure cover 7 between the receiving element 1 and the outlet opening 9 or the mouth 33 , as shown in FIG. 5 .

FIGS. 11 and 12 again show a closure cover 7 of the same type as in FIG. 4 or 7 , wherein here a receiving element 1 which does not occupy the entire width of the closure cover 7 is shown (cf. FIG. 13 ). The receiving element 1 here has an essentially rectangular shape, wherein a part (here the narrow side) of the peripheral surface 17 forms a liquid-tight closure of the opening 12 in the peripheral surface 36 of the closure cap. The rest of the peripheral surface 17 lies within the peripheral surface 36 in the feeding position of the receiving element 1 .

The receiving element 1 has a flat, liquid-permeable cover surface 21 and a bottom surface 16 . In order that liquid cannot flow sideways through the receiving element 1 , a stop (insert) 39 is provided in the interior of the closing cover 7 in the region extending over the height of the receiving element 1 , which closes the closing cover 7 on the receiving element. 1 (in the feeding position) and the peripheral surface 36 of the locking cover 7, see FIG. 14 . Guides (protrusions, grooves) that cooperate with corresponding guides on the receiving element 1 can be mounted on the stop (insert) 39 and/or at other points on the inner side of the closure cover 7 The receiving element 1 can be pushed into and pulled out of the closure cover 7 along the guide.

In general, for all embodiments with a movable receiving element 1 , guides can be provided on the receiving element 1 and/or on the inner side of the closure cover 7 .

The receiving element 1 in FIG. 13 can have a cover surface 21 that can be folded up so that the feeding body 2 can be replaced. However, the receiving element 1 can also be produced as a disposable product, in which case the receiving volume 12 is inaccessible, that is to say the feed body 2 cannot be removed (the bottom surface 16 and the cover surface 21 are non-detachably connected to the peripheral surface 17), and for placing Inserting another feed body 2 has to replace the entire receiving element 1.

However, the receiving element 1 in FIG. 13 can be formed without the cover surface 21 , wherein the receiving volume 20 is then lockable with the further element 13 similarly to FIG. 2 .

FIGS. 15 and 16 also again show a closure cover 7 of the same type as in FIGS. 4 , 7 or 11 . The receiving element 1 is now fastened torsionably on the closure cover 7 by means of a hinge 41 arranged here parallel to the longitudinal axis 10 of the closure cover 7 . In this case, the hinge 41 can be fastened to the closure cover 7 , for example at a vertical web arranged outside the peripheral surface 36 . The receiving element 1 can be manipulated (turned horizontally or swiveled out) by means of the projection 19 .

The receiving element 1 can now be constructed in such a way that the peripheral surface 17 of the receiving element surrounds the receiving element (that is, here has the shape of a cylindrical jacket) and in the feeding position ( FIG. 15 ) puts the peripheral surface 17 on top. The closure cover 7 is closed with the peripheral surface 36 in a liquid-tight manner from below. The opening 12 of the closure cap is in this case in the shape of a cylindrical jacket, against which the entire casing 17 of the receiving element 1 can be closed in a liquid-tight manner in the operating position 8 of the closure cap 7 .

Here again, the receiving element 1 itself can surround the receiving volume 20 by means of the cover surface 21 and the bottom surface 16 . It is then also conceivable that the receiving element 1 is already equipped in production with the feed body 2 and that the peripheral surface 17 , the cover surface 21 and the bottom surface 16 are non-detachably connected to one another. The receiving element 1 can be a disposable product, then in order to replace the feeding body 2 the receiving element must be removed from the hinge 41 and a new receiving element 1 with the feeding body 2 contained therein must be hung on the hinge.

The receiving element 1 can also be formed without the cover surface 21 , but in this case a further element 13 must be arranged between the receiving element 1 and the outlet opening 9 , similar to FIG. 2 .

However, the receiving element 1 (and the housing 36 of the closure cover 7 ) can also be designed as in FIGS. 9 and 10 . In the case of FIG. 9 , the hinge 41 acts on the vertical end of the peripheral surface 17 . In the filling position, feed body 2 can be inserted between bottom surface 16 and cover surface 21 where no peripheral surface 17 is present. In the case of FIG. 10 , since the feed body 2 can be easily inserted from above into the bottom surface 16 due to the absence of the cover surface 21 , a further element 13 in the closure cover 7 closes the receiving volume 20 upwards. In both the embodiments according to FIGS. 9 and 10 , the peripheral surface 17 can close the opening 12 in a liquid-tight manner.

The receiving elements in FIGS. 4 to 16 can of course also be used for other types of closures with a corresponding adaptation of the closure cover and the receiving element. Thus, for example, a receiving element 1 that can be unscrewed from the closing cover as in FIGS. 15 and 16 or a narrower receiving element 1 as in FIG. 13 can also be used for the closing cover 7 in FIG. 1 .

In general, all twistable or displaceable embodiments of the receiving element can also be embodied in such a way that they do not form part of the peripheral surface 36 of the closure cover 7 in the feeding position. For this purpose, the receiving element must be dimensioned to be smaller perpendicularly to the longitudinal axis. Thus, for example, the opening 12 in FIG. 16 is partially blocked by the peripheral surface 36 of the blocking element 7 (as in FIG. 8 ), and the remaining opening 12 can be closed liquid-tightly by a cover (slide, etc.), in order to avoid cover wear, The cover can be hinged on the outside of the locking cover 7 . The cover can here form part of the peripheral surface 36 of the closure element.

In all embodiments in which the opening 12 is liquid-tightly closed by the receiving element 1 or a part of the receiving element 1 (for example by a part of the peripheral surface 17), a locking device is provided on (a part of) the receiving element 1, which locking device When the receiving element 1 is pushed into the locking cover 7 , it is closed with the locking cover 7 . In this case, the locking device can overlap and lock the locking cover 7 at both ends. The same principle of latching can be used when the opening 12 (as explained above) is latched by its own cover.

In order to create a tight seal between the cover or receiving element 1 on the one hand and the closure cover 7 or its peripheral surface 36 on the other hand, a sealing device can additionally be provided.

FIG. 18 shows a schematically shown cutaway triaxial view of a tablet 2 which can be arranged in a receiving element 1 according to the invention. In the case of the embodiment of tablet 2 shown in Figure 18, said tablet has a cylindrical shape. This shape again belongs to the embodiment of the receiving element 1 shown in FIG. 6 . However, it is of course also conceivable to arrange the tablet 2 from FIG. 18 in the receiving element 1 from FIG. 3 or that the shape of the tablet 2 does not have to correspond in principle to the receiving volume 20 .

However, the condition that must be met in any case is that the feed body volume 24 of the tablet 2 must not be larger than the receiving volume 20 .

In order to permanently hold the tablet 2 in the infeed body shape 22 , the tablet 2 has a mesh 23 which is arranged on the infeed body outer side 26 .

FIG. 18 also shows that the feed body volume 24 is partially filled with a plastic sponge 25 . Furthermore, spherical bodies 27 are provided in the feed body volume 24 . Here, liquid 37 can be squeezed through plastic sponge 25 to bulb 27 . The mesh fabric of the scrim 23 is likewise permeable for liquid 37 .

The spherical body 27 functions as a water-soluble element in order to produce a drink or to release flavors and/or nutritional and/or food additives and/or medicinal active ingredients so that it can be mixed with the liquid 37 . For this purpose, the spherical body 27 is configured according to the cross-sectional view in FIG. 19 . That is, each spherical body 27 has a surface 29 made of a water-soluble glaze layer 28 , preferably sugar. The glaze layer 28 delimits the spherical interior 30 and has a certain glaze layer thickness 31 . The substance to be mixed with the liquid 37 , in particular flavoring and/or nutritional and/or food additives and/or medicinally active ingredients, is provided in the spherical interior 30 . In the embodiment of FIG. 19 , the spherical interior 30 is filled with syrup 32 .

Only when the glaze layer 28 with the glaze layer thickness 31 dissolves does the release of the syrup 32 or its mixing/incorporation with the liquid 37 take place.

The glaze layer thickness 31 can be of different sizes in different spherical bodies 27 , so that the dissolution duration of the glaze layer 28 is different. Accordingly, the time course of mixing the syrup 32 can be designed. Furthermore, different spheroids 27 may contain different substances within their respective spheroid interiors 30 . Thus, some spheres 27 may contain syrup 32 and other spheres 27 may contain other substances in order to provide an isotonic drink, for example after a certain time, ie after the spheres 27 have been in contact with the liquid 37 for a certain duration.

Furthermore, the spherical bodies 27 themselves can be of different sizes, ie have different diameters, as shown in FIG. 18 . Thus, in interaction with different glaze layer thicknesses 31 , depending on the duration of contact of the sphere 27 with the liquid 37 , different amounts of the substance present in the sphere interior 30 , eg syrup 32 , can be released.

Finally, it is of course also possible to arrange different substances (not necessarily syrup 32 as explained above) in differently sized balls 27 with different glaze layer thicknesses 31 . Thus, it is possible to determine the temporal course of the mixing of different quantities of different substances with the liquid 37 .
