Description

Drinking device with a conveyor

The invention relates to a drinking device with a cap having a drinking opening for closing a drinking container, which has a receiving chamber for liquid ^¬ , and a conveyor for conveying liquid from the receiving chamber, wherein the conveyor has an inner wall element, which in an outer wall element below Forming a gap is added, the

Interspace between the wall elements defines a conveyor channel which is connected via an inlet opening with the receiving chamber.

From US 7,210,596 Bl a drinking container for children is known, which has a substantially cylindrical outer vessel into which a corresponding insert is inserted. The insert has spacer elements on its outer wall, so that a cavity is formed between the insert and the outer vessel. In addition, the use of foot elements from the bottom of the

Remote vessel placed so that liquid can flow into the cavity. At the open end of the outer vessel is a

cup-shaped lid attached at the bottom of a plurality of openings for discharging the flowing through the cavity between the outer vessel and the insert liquid is provided. This design is designed to make it easier for children to learn to drink from a cup. However, the use of the container is relatively complicated because the cup-shaped lid for liquid removal over a comparatively large

Angle must be pivoted. Another disadvantage of this embodiment is that the liquid flows after entering the cup-shaped lid substantially uncontrolled to the top discharge opening, so that a targeted

Liquid removal is difficult.

In US 4,442,948 A a drinking container is disclosed, which consists of two nested cases. Between the outer and inner sheath, a spiral liquid channel is defined which leads to an outlet at the cup rim.

The US 4,016,998 A relates to a drinking container, in which a Drinking straw is integrated. The drinking straw connects an upper ^¬ side drinking opening via two separate channels with a bottom-side inlet opening.

Furthermore, in the US 2006/0006 182 AI a drinking bottle for children with a drinking process is shown, which is connected via a channel with an opening in the bottom area of the bottle.

From US 6,755,318 B2 a different type of drinking container for dispensing a metered amount of liquid when pivoting in a drinking position is known. The drinking receptacle has a ^¬ In nenteil with a drinking spout, which is inserted into a center part, which is in turn received in an outer part. The space between the bottom and side walls of the inner and middle part defines a chamber for receiving the metered liquid ^¬ keitsmenge. The chamber is connected to the liquid ^reservoir in the outer ^¬ part via a narrow opening which is arranged with sufficient pivoting above the liquid level, so that a subsequent flow of liquid is prevented in the chamber. In most cases, however, a dosage of liquid delivery when drinking is not desirable; Moreover, it is also necessary in this device to pivot the container according to the drinking from a cup in a drinking position.

In contrast, the object of the present invention is to provide a structurally simple, inexpensive to produce drinking device of the initially mentioned kind, which is improved in terms of the above disadvantages known drinking container. Accordingly, the user of the drinking device should in particular be enabled to precisely control the liquid transport between the receiving chamber and the drinking opening while drinking.

This is achieved in the drinking device of the initially defined kind characterized in that the feed channel is connected in the Ver ^¬ closure cap adjacent region with an annular distribution channel with the drinking opening in

Connection stands. In use of the drinking device, the liquid flows from the receiving chamber into the conveying channel between the wall elements and subsequently into the annular distribution channel, which defines a circumferential cavity for distributing the inflowing liquid, which is connected to the drinking opening. The annular distribution channel is advantageously connected over its entire circumference with the delivery channel, so that a uniform inflow of liquid can be achieved. The drinking device enables precise, well kon ^¬ grained steering of the fluid flow between the on ^¬ receiving chamber and the drinking opening, in which the desired amount of liquid is reliably provided. The annular distribution channel ensures that the drinking opening when

Drink evenly with liquid. In addition, for a variety of drinking positions a liquid removal take place, so that the ease of use of the drinking device

is significantly increased. For this purpose, it is particularly advantageous if the gap between the outer wall element and the inner wall element is designed as a gap such that when creating a suction pressure at the drinking opening liquid against gravity through the conveyor channel in the annular

Distribution channel flows. Thus, the drinking device can be used like a conventional drinking straw. This embodiment has the advantage that the drinking device regardless of the

Position of the drinking container, so even in a vertical or unverschwenkten position, can be used. Thus, a variable usable drinking device is created with great user comfort, which is also characterized by a well-controlled fluid removal. By the drinking opening is arranged in the cap, further unwanted spilling of liquid is largely avoided.

For uniform distribution of the liquid in the annular distribution channel, it is advantageous if the extension plane of the distribution channel is arranged substantially parallel to a lower contact surface of the drinking container. This results in a uniform distribution of the liquid flow

ensured when the drinking container is arranged in a substantially upright or unverschwenkten position. In order to form the annular distribution channel in the area adjacent to the closing ^¬ cap area, it is advantageous if the annular distribution channel is formed by a circumferential From ^¬ recess or depression, which is bounded at least by snap-side end portions of the wall elements of the conveyor; In addition, the distribution channel may be delimited at the top by a seal, in particular a silicone seal, provided on the inner surface of the closure cap.

In order to connect the annular distribution channel in a structurally simple manner to the delivery channel of the conveyor, it is advantageous if the outer wall element of the Fördereinrich ^¬ tion in the closure end portion has a peripheral flange with a particular open to the inner surface of the closure cap recess. The circumferential flange thus extends radially outward from the outer wall element of the conveyor. The annular distribution channel therefore expediently has a greater width or radial extent than the delivery channel between the outer and the inner wall element. To limit the annular distribution channel radially outward, a ^{circumferential,} running in the longitudinal direction projection of the flange is preferably provided. To limit the annular distribution channel radially inward, a continuation of the inner wall element in the axial direction is preferably provided.

For uniform delivery of liquid from the receiving chamber, it is advantageous if the wall elements with respect to their

Longitudinal axes are rotationally symmetrical. In a preferred embodiment, the longitudinal axis of the outer wall element substantially coincides with the longitudinal axis of the inner wall ^¬ elements. In this way, a conveying channel with a constant in Wesent ^¬ union width is achieved in the circumferential direction of the conveying channel; Preferably, the conveyor channel also has a substantially constant width over its entire length between the inlet opening and the annular distribution channel.

It has also been found to be advantageous if the inner wall element at least three, preferably six, in Circumferentially spaced locations on the outer wall element is present, which points are preferably formed by formed on the outer wall element support lugs. Consequently, a

Contact between the inner and outer wall element between the abutment points can be avoided and the cross section of a transition from the conveying channel to the distribution channel can in

Substantially be maintained according to the cross section of the conveying channel, so that a passage of a liquid from the conveying channel or from the intermediate space between the wall elements is facilitated in the distribution channel.

In a preferred embodiment, it is provided that the wall elements are substantially conical, distinct from

have closure-side end portions to bottom end portions tapered shape. Alternatively, a substantially cylindrical shape of the wall elements may be provided.

In order to ^¬ reliably in an arbitrarily inclined position of the drinking container to promote liquid in the conveying channel between the wall ^¬ elements, it is advantageous if the inlet ^¬ opening between the bottom end portions of the wall elements of the conveyor is arranged circumferentially. By the inlet opening ^¬ runs between the bottom end portions of the wall elements, a nearly complete emptying of the receiving ^¬ chamber is made possible by means of the conveyor; the circumferential inlet opening also ensures that liquid can flow into the conveying channel regardless of the position of the drinking container during the drinking process.

In order to substantially completely empty the receiving chamber of the drinking container with the drinking device, it is advantageous if the inlet opening into the conveying channel adjoins a bottom of the drinking container.

In order to prevent the leakage of liquid from the drinking container, it is advantageous if the drinking opening has a valve, in particular a slit membrane opening under a suction pressure.

To reliably a liquid-tight connection between the To achieve drinking container and the flap, it is advantageous if a sealing element is arranged in the attached to the drinking container state of the cap between the drinking container and the cap.

In this context, it has proven to be advantageous if the closure cap has a recess, so that an air gap between the closure cap and the sealing element remains in the region of the recess. Where appropriate, the air gap, in conjunction with an air inlet opening, as described below, allows pressure equalization in the air gap

A drinking vessel. If the recess is provided only at one, preferably the drinking opening opposite, body, the tightness of the container is hardly affected.

For example, the recess in the manner of a groove in a wall otherwise close to the sealing element

Be provided cap.

In order to avoid the formation of unwanted high underpressure in the drinking container ^¬, it is advantageous if the closure has ^¬ cap an air inlet opening. In order to allow only an air inlet through the air inlet opening, however, to avoid an unwanted liquid leakage, it is advantageous if the formation of a ventilation valve of the

Air inlet opening is associated with a sealing flap. The sealing flap can in this case be provided in particular only in the region of the air inlet opening, so that a material-saving, cost-effective design is achieved. Alternatively, instead of the only locally formed sealing flap, a circumferential sealing lip may also be provided.

When using a sealing element as stated above, the sealing flap may advantageously be integral with the

Be formed sealing element, wherein the sealing flap

preferably rests under pretension on the cap.

Accordingly, the sealing element at least section ^¬ forms a one-way valve, which - according to a sealing ^¬ function - on the one hand prevents the liquid leakage and at the same time - according to a ventilation function - the pressure equalization by air supply from the outside into the drinking container allows. By means of the already circumferential sealing element can easily a circumferential sealing lip through the

Be formed sealing element which bears under pretension on the cap. In addition, a, preferably circulating, air channel between the sealing element and cap can be provided so that largely independent of the position of the drinking device in the room or their inclination to a

arbitrary position along the sealing lip pressure compensation can be performed.

Another preferred variant of the sealing of the

Air inlet is that for training e

Ventilation valve of the air inlet opening is associated with a Schirmvent. The umbrella valve allows a still white

Material savings and also increases the reliability

Ventilation valve, as it is less sensitive to

Fatigue is as a flap valve.

Furthermore, it is favorable for an easy-to-use liquid removal, if with the cap a preferably

connected to the neck-shaped mouthpiece, which has the drinking opening. It is further advantageous if the mouthpiece made of an elastic material, preferably silicone. With regard to a small number and thus cost-effective configuration, it is advantageous if the mouthpiece is formed integrally with the sealing element.

If a rotatably mounted, at least one recess having, with the mouthpiece cooperating cover is connected to the cap, the cover can be positioned in a drinking position such that the elastic mouthpiece protrudes through the recess. On the other hand ^¬ rotate the cover the mouthpiece and in a storage position between the cover and the closure cap at Ver

to be ordered.

In a particularly preferred disclosed embodiment of the invention it is provided that an outer wall of the drinking container is provided as an outer wall member of the conveyor Rich ^¬ processing. Accordingly, the drinking device is in this embodiment in the drinking integrated. The inner wall element is advantageously thin-walled, so that the arrangement of the conveying Rich ^¬ tung only slightly reducing the receiving volume of the receiving chamber in the drinking container. The space between the outer wall and the inner wall element is at least partly filled, in use, with air, so that a very good thermoinsulating ^¬ for the pre-preserved in the liquid receiving chamber is achieved. Therefor, it is favorable when the intermediate space between the outer wall and the inner wall element as a narrow gap being formed ^¬ is such that the liquid stored the Trinkbe ^¬ hälters only slightly penetrates into the conveyor channel. According to ^¬ the delivery channel is at least partially filled with air in view of a good insulating effect of the drinking device; For liquid removal from the receiving chamber, a suction pressure can be applied to the drinking opening, which causes an inflow of liquid into the conveying channel while displacing the air contained therein.

For filling or refilling the drinking container, it is advantageous if the outer wall of the drinking container connecting ^¬ medium, in particular a thread or a part of a

Ba onettverschlusses, for releasable connection with corresponding connection means of the closure cap. If the annular distribution channel is formed on closure-side end regions of the wall elements integrated in the drinking container, this embodiment can also provide the advantage that the liquid-conducting connection between the drinking opening and the annular distribution channel is independent of the relative position of the releasable connection means.

In an alternative preferred embodiment, the form is

provided that the closure cap and the conveyor form an insert for a separate drinking container. In a use position the drinking device is on the

Drinking container attached; the drinking container thus forms no part of the drinking device in this embodiment. Of the

Drinking container therefore has at least one of the wall elements of the drinking device separate outer wall, which includes the receiving chamber with a bottom portion. In order to attach the drinking device to the separate drinking container, it is favorable if the insert has connecting means for detachable connection to the separate drinking container. The closure cap of the insert preferably has a hood-shaped connecting element in the form of a cap which fits to the closure-side end region of the separate drinking container and expediently carries a thread.

To achieve a conveyor m the type of drinking straw, it is advantageous if the insert has an elongated, half-like conveyor, which projects in use before preferably centrally in the receiving chamber of the separate Trinkbe container. To also inside the conveyor

To be able to absorb liquid, it is advantageous if the inner wall element encloses a cavity.

The invention will be explained below with reference to preferred embodiments illustrated in the figures, to which, however, it should not be restricted.

FIGS. 13 and 14 are each a perspective view of the drinking device shown in FIGS. 10 and 12.

In Fig. 1, a first imple mentation of a drinking device 1 for a drinking container 2 is shown, which includes a receiving chamber 3 for liquid. The drinking device 1 has a removable closure cap 4 with a mouth piece 5, which has a drinking opening 6. In addition, a conveyor 7 is provided, which is adapted to convey liquid from the receiving chamber 3 into the drinking opening 6. The

Conveyor 7 has an inner wall element 8, the is disposed within an outer wall member 9. In the embodiment shown in Figs. 1 to 3 is the outer

Wall element 9 formed by an outer wall 9 'of the drinking container 2, which defines the receiving chamber 3 with an integrally with the outer wall 9' running bottom 9 ''. The inner wall element 8 is held over the closure cap 4 in the outer wall element 9. The conveyor 7 and the

Cap 4 are suitably made of a hard

Made of plastic material.

1, the wall elements 8, 9 are essentially rotationally symmetrical with respect to a common longitudinal axis 10, which simultaneously represents the longitudinal axis of the drinking container 2. When shown

Embodiment, the wall elements 8, 9 a in

Essentially conical, tapered from the closure-side end portions to bottom end portions shape.

As further seen in Fig. 1, the wall elements 8, 9 of the conveyor 7 enclose a gap defining a conveyor channel 11 for transporting liquid. The delivery channel 11 extends with a constant width over the entire length of the wall elements 8, 9, so that a uniform flow with liquid is ensured. The conveying channel 11 is connected to the bottom 9 "of the drinking container 2

adjacent inlet opening 12 with the receiving chamber. 3

connected. The conveying channel 11 between the wall elements 8, 9 is designed as a narrow gap with a width of about 0.3 to 0.5 mm, which is normally filled with air, so that the liquid contained in the receiving chamber 3 thermally

is isolated. Thus, a drinking container 2 is provided, which is particularly well suited to preserve the temperature of a beverage contained in the receiving chamber 3, ie, in particular a hot or cold drink. Upon application of a negative pressure on the mouthpiece 5 liquid flows from the receiving chamber 3 via the inlet opening 12 into the conveying channel 11, wherein the air normally contained in the conveying channel 11 is displaced. Thus, in the drinking container 2 by means of the conveyor 7 liquid sucked in the manner of a drinking straw from the receiving chamber 3 to the drinking opening 6 of the mouthpiece 5 become. In order to avoid unwanted liquid leakage, the drinking opening 6, a valve 6 'on. Conveniently, a flexible slit membrane is provided as the valve 6 ', which closes the drinking opening 6 at atmospheric pressure, but forms an opening with the application of a suction pressure, so that liquid can flow through.

As can further be seen from FIG. 1, the delivery channel 11 is connected in a region adjoining the closure cap 4 with an annular distribution channel 13, which communicates with the drinking opening 6 formed in the mouthpiece 5. When creating a suction pressure on the mouthpiece 5 flows in

Longitudinally guided by the conveying channel 11 liquid over a circumferential passage opening in the annular distribution channel 13, which is thus supplied over its entire circumference from the conveying channel 11 with liquid. The plane of extension of the distribution channel 13 is parallel to a lower support surface 2 'of the drinking container is substantially arranged ^¬ 2 so that takes place in a horizontal position of the drinking container 2, a uniform annular distribution channel in the Flüssigkeitseinströmung. 13 In order to form the annular distribution channel 13, in the closure-side end regions of the wall elements 8, 9 there is provided a circumferential projecting flange 13 'with a depression or recess 14 through which the distribution channel 13 is formed. The distribution channel 13 is bounded radially outwardly by the circumferential, arranged in the longitudinal direction of the drinking container 2 projection or flange 15; for limiting the distribution channel 13 radially inward is a continuation of the inner wall element eighth

intended .

As is further apparent from FIG. 1, the closure cap 4 is detachably fastened to the drinking container 2 by means of a threaded connection 16. The outer wall 9 'of the drinking container 2 has a

Threaded on with an appropriate thread of the

Cap 4 is engaged. Of course, the cap 4 can also be connected via a snap connection or the like with the drinking container 2.

Between the cap 4 and the drinking container 2 is a Seal 17 arranged so that an unwanted ^{Flüssigkeitsaus ¬} occurs on the thread 16 is prevented. With the seal 17, a circumferential sealing lip 18 is also integrally formed, which bears against the cap 4 under prestress; By this means, a ventilation valve 19 is formed, via which a controlled air inlet in the direction of the arrow 20 'can take place via an air inlet opening 20 provided in the closure cap 4 into the receiving chamber 3. The vent valve 19 is in this case designed with respect to the drinking valve 6 'such that after discontinuation of a suction pressure for drinking a slight negative pressure remains, so that liquid is sucked back into the drinking container 2.

With the seal 17 further the mouthpiece 5 is integrally formed, which is therefore elastically deformable. With the help of a cover 21 rotatably mounted on the cover 21, which has a recess 22, the mouthpiece 5 can therefore be positioned either in the drinking position shown in Fig. 1 or - if the cover 21 is arranged such that the recess 22 is not is arranged in the region of the mouthpiece 5 - in a depressed Verwahrstellung between the cap 4 and the cover 21st

In Fig. 2, an alternative embodiment of the vent valve 19 is shown. Here, a circumferential sealing lip 18 is not provided as in the embodiment of FIG. 1. The cap 4 is connected via the seal 17 is substantially airtight with the drinking container 2. In the region of the mouthpiece 5, however, the closure cap 4 has an air inlet opening 20, so that air can enter the receiving chamber 3 in the direction of the arrow 20 '. The air inlet is controlled by a - provided only in the air inlet opening 20 - sealing flap 18 ', which is integrally formed with the seal 17 and the mouthpiece 5 and biased against the cap 4 and thus the air inlet opening 20 at the same

Pressure level inside and outside the receiving chamber 3

closes. If a certain negative pressure in the

Receiving chamber 3 due to the installation of a suction pressure on

Mouthpiece 5 occurs, lifts the sealing flap 18 'of the

Cap 4 and thus gives an air inlet over the Air inlet opening 20 for the purpose of pressure equalization free.

It is advantageous in this embodiment of the vent valve 19 in particular that due to the only in the field of

Air inlet opening 20 provided sealing flap 18 'a significant material savings compared to the circumferential sealing lip 18 shown in Fig. 1 can be achieved.

In Figs. 4 to 6 is a basically similar

From guide form of the drinking device 1 shown in FIG. 1 or FIG. 2, wherein the ventilation valve 19 is formed by an umbrella valve. The umbrella valve comprises an inner screen part 23 which seals a valve space 24 formed in the cap 4. The shield part 23 is integrally formed with the seal 17 and the mouthpiece 5 and therefore elastic

deformable. The valve space 24 has the shape of a stepped cylinder, wherein a lower part of the valve space 24 is adapted to receive the screen part 23 and the cross section of an upper part is tapered relative to the lower part so that an outer edge 25 of the screen part (see FIG ., 7) bears tightly against the step formed in the valve space 24. The upper part of the valve chamber is connected to an air inlet opening 20, so that the air pressure in this part corresponds to the ambient pressure. The lower part of the valve chamber 24 is connected by a recess 26 in the screen part or in the seal 17 with the receiving chamber 3. As soon as the pressure in the receiving chamber 3 falls below a certain level, the screen part 23 deforms in such a way that its outer edge 25 deforms from the step in FIG

Valve space 24 lifts and air from the upper part in the lower part of the valve chamber 24 is transmitted. Conversely, the tight closure of the shield member 23 with the valve chamber 24 prevents, for example, contained in the receiving chamber 3

Liquid passes through the valve chamber 24 to the outside.

In addition to the different types of vent valve 19, the seal 17 of the embodiment shown in Fig. 4 to 6 leadership form a

prestressed collar 27, which closes tightly with the inner wall element 8. The collar 27 extends over the entire circumference of the seal and is biased against the inside of the inner wall member 8 by having a substantially flared conical shape, which is elastically deformed by the arrangement in the inner wall element 8.

As can be seen from the comparison of FIGS. 5 and 6 and shown in detail in FIG. 8, the inner wall element 8 is suspended in the outer wall element 9 in at least three, preferably six sections. The suspension can be formed by, for example, on the inside of the outer wall element 9

Supporting lugs 28 (see Fig. 8) can be achieved, on which a reverse projecting flange 29 of the inner wall element 8 rests in sections. The projecting flange 29 is rotationally symmetrical over the entire circumference of the inner

Wall element 8 is formed, while the support lugs 28 are arranged at a distance, so that the conveying channel 11 between the wall elements 8, 9 in the areas between the support lugs 28 substantially unhindered in the distribution channel thirteenth

extends, as can be seen in particular in Fig. 6.

In the embodiment shown m Fig. 5, the inner wall element 8 at least two inlet openings 12 which connect the conveyor channel 11 with the receiving chamber 3. The inlet openings 12 are provided at the lowest points of the na inwardly curved bottom 9 '' to allow complete emptying of the receiving chamber 3.

As shown in Fig. 8 but also Fig. 5 and 6, seen in the illustrated embodiment, the closure cap 4 by means of ei ^¬ ner rotary latching connection, preferably by means of a bayonet fitting, removably attached to the drinking container 2 and the outer wall element 9. The outer wall element 9 of the drinking container 2 has latching grooves 30, into which the corresponding connecting elements 31 of the closure cap 4 can be inserted.

In the embodiment shown in Figs. 9a, 9b and 9c, the seal 17 also has a collar 27 which extends from a sealing plane defined by the upper edge of the inner wall member 8 down to the bottom 9 '' (not shown) ). In addition, the seal 17 forms a sealing groove 31 which extends concentrically from the sealing plane upwards to the closure cap 4 Sealing rings 32 is formed. The sealing rings 32 are integrally mitgeformt with the seal 17. An inner,

vertical wall 33 of the cap 4 is tightly received in the sealing groove 31, so that a liquid leakage from the receiving chamber 3 between the inner wall member 8 and the cap 4 is prevented by the seal 17. Accordingly, a radially outer sealing ring 34 of the seal 17 relative to that shown in FIG

Embodiment be reduced. The radially outer

Seal member 35 is shown in Figs. 9b and 9c

Seal mainly for sealing the gap between the inner wall member 8 and the outer wall member. 9

set up and is for this purpose with a groove 36 formed by the outer wall member 9 in engagement.

In the embodiment shown in Fig. 9b is the

Pressure equalization preferably provided by the seal 17 formed screen valve of FIG. 7 is provided. This can be arranged, in particular, on a side opposite the mouthpiece 5, so that it is not shown in the angled sectional view shown on the basis of the selected angle (compare Fig. 9a).

Unlike FIG. 9b, FIG. 9c shows a planar longitudinal section. In contrast to FIG. 9 b, the radially inner sealing ring 32 of the seal 17 is shaped in the manner of a circumferential sealing lip and thus forms a sealing flap 32 ', which under

Preload inside abuts the vertical wall 33 of the cap 4. So that an air inlet between the wall 33 and the sealing flap 32 'is made possible, a region-wise recess 33' is provided on the closure cap 4, in particular on the radial outside and on the lower edge of the vertical wall 33. The recess 33 'is preferably provided at a location opposite the mouthpiece 5 in the cap 4. It may be formed in particular in the manner of a perpendicular and / or radially extending groove or notch in a wall of the closure cap 4. Due to the due

Recess 33 'achieved distance between the wall 33 and the seal 17 and the outer sealing ring 32, an air gap between the two elements is formed, which with one of the sealing flap 32 'limited, provided in the seal groove 31 circumferential air passage 31' communicates. Of the

Air duct 31 'extends within the bulbous shaped

Sealing groove 31, which is thus not completely filled by the annular wall 33 in plan.

In order to avoid the formation of a negative pressure in the interior of the closure cap 4, an air inlet opening 20 is provided in the region of the recess 33 'in the closure cap 4. During pressure equalization, the air flows from the outside through the air inlet opening 20, through the air gap formed by the recess 33 'into the air duct 31' and the sealing flap 32 'is lifted from the wall 33 at least at one point along the circumference due to the pressure difference the air from the air duct 31 'enters the drinking container 3. In this way, the seal 17 forms with the cap

Ventilation valve 19.

In Figs. 10 to 14 is an alternative embodiment of

Drinking device 1 shown, which is designed as an insert part 1 'for a separate drinking container 2. The insert 1 'has an elongated conveyor 7 in the manner of a drinking straw positioned in a manner shown in Fig. 11 use ^¬ position centrally located in the receiving chamber 3 to the separate drinking container 2. In this embodiment, separate from the outer wall 9 'of the container 2 wall elements 8, 9 seen ^¬ , which of an attached to the cap 4 end portion to an opposite free end portion

are formed funnel-shaped tapered. The insert 1 'is suitably dimensioned so that the wall elements 8, 9 protrude in the use position to a bottom 9' 'of the matching drinking container 2. In the embodiment shown, an inwardly curved bottom 9 '' is provided. The inner

Wall element 8 encloses a central cavity 37, so that fluid 37 can be accommodated in this cavity as well.

As can be seen from Fig. 10, 11, the conveying channel 11 between the wall elements 8, 9 and in the region of

Cap 4 to the conveyor channel 11 subsequent

annular distribution channel 13 substantially corresponding to the With reference to FIGS. 1 to 3 explained embodiment formed, so that the above explanations

can be referenced. Here, an angled end portion of the outer wall element 9 is provided, which surrounds the

Flange 13 'and the projection 15 for limiting the

annular, in the form of a recess 14 formed
