Requirements for drinking bottles are

• In the closed state, absolute tightness is expected, leakage is to be avoided under all circumstances - provided correct handling
• The transport position has no influence on the functionality and the tightness of the bottle
• Overpressure must be kept in the bottle for reasons of taste
• When removing liquids, there must be no overpressure in the bottle - eg due to carbonated drinks or due to a different altitude
• During the emptying of the bottle, no vacuum should build up in the bottle
• The bottle allows the use of a drinking straw and can be emptied through a drinking straw
• The contents of the bottle can contain different viscosity media - from thin to pasty; the outflow / flow should be adjusted accordingly
• The bottle must be easy to handle and safe to use; sometimes a one-handed operation is required
• The drinking bottle must meet various requirements or form a species; a kindergarten application may differ from the cycling application
• The coating of the interior of the bottle must guarantee taste neutrality
• The bottle must meet hygiene requirements; It must be easy to disassemble and clean - especially regarding the bottle cap
• The manufacturing processes used and materials used must meet conditions such as medical device ordinance, food ordinance; Admission restrictions must be observed
• Nevertheless, the production cost must remain manageable, the number of parts must be kept low, reuse parts must be respected.

The substantially cylindrical bottle body is adapted depending on the application - either smooth hollow cylindrical body e.g. made of metal, aluminum, with interior and exterior paint or coating, easy to maintain, or - for competitive sports, especially cycling - here the bottles are also referred to as Bidon, or demanding leisure - made of plastic material, injected or blown, with a Receptacle for a rod attachment and a grip - not too soft - for one-handed operation. At the top of the bottle with filler opening the attachment for the bottle cap is provided, usually an inner or an external thread made of plastic - injection-molded with metal bottles and secured against rotation. For reasons of hygiene, the care of an external thread is more accessible.

The bottle closure must fulfill a number of functions; It must be a shutter operated with one-handed operation of the bottle. Are provided with the mouth opening through a mouthpiece, moving in the axial direction locks, as well as axially moving locks, which are about a screw or worm drive by manual rotation of the cap - usually only two-handed to be driven. Furthermore, closures are known, which are operated by rotation of superimposed sealing discs with eccentric openings or discs with outwardly guided levers - sliders. Taking into account that the bottle closure includes several operating conditions that must be handled and operated - also for children - and also from the viewpoint of ease of care, provides a bottle closure with automatic valve reset function, which ensures a tight bottle closure when not in use in any case , a significant product benefit and competitive advantage.

In the following the state of the art of closures of drinking bottles for beverage storage for school, sports, travel and leisure - especially of closures of children's bottles for beverage storage for school, sports, travel and leisure with automatic valve reset function - appreciated; According to the prior art, depending on the application, a variety of types of closures for bottles for beverage storage for school, sports, travel and leisure - especially from closures of children's bottles for drinks storage for school, sports, travel and leisure - in use.

The European patent application EP 1 890 945 / American registration US 2009 277 907 / Canadian registration CA 2 610 734 / international registration W02006 / 131 002 discloses a closure for a drinking bottle, consisting of a screwed in a drinking bottle neck cap and a shut-off and opening device which has a fixed relative to the cap fixed part and a relative to the cap axially displaceable sliding part which is to move from a closed position to a drinking position , which allows the outlet of the bottle contents from the bottle. The sliding part is so resiliently mounted around the fixed part, that at least one return means with a force in the direction of action of the cap away, outwardly, acts on the sliding part. The sliding part is in the closed position in the outer position and is for the transition to the drinking position on the cap to move inwards, against the resistance of at least one return means. Fixed part and sliding part have the sealing function of the bottle held; if the calotte of the fixed part is mechanically damaged by human bite, the tightness is no longer present. The sliding part with the return spring allows only the closed position in a rest position.

According to the German utility model DE 20 2006 016 173 / Patent DE 10 2007 050 000 a bottle with screw cap and integrated drinking straw is presented such that the straw stem bottoms flush and possibly schraubkappenbündig at least once folded diagonally in the bottle befindlich opening the screw - for the purpose of obtaining its manufacturing state - its container springs.
Bottle contents and drinking straw material must be coordinated. The straw end of the bottle should not contain any bottle contents.

The American patent US 2002/179 616 describes the execution of a 'lip-operated valve closure for a bottle consisting of a cap with internal thread for bottle assembly, with each inside and outside hollow cylindrical Rohransatz and centrally located, outside valve element, the outer tube approach a centrally perforated cup-shaped, axially movably arranged cap leads, between the valve element and a hollow cylindrical elastomer sealing and fitting is clamped as a membrane element. When a force is applied to the cap in the axial direction of the bottle, the membrane element buckles at a predetermined hinge point and opens the sealing closure between its annular lip and the undercut collar of the valve element.
Since the membrane element acts like a spring, there is no more static state than that of the closed valve; the withdrawal flow rate is determined by the pressure on the membrane element. A drinking straw can not be used.

The German patent DE 196 30 579 / European patent specification EP 822 149 presents a drinking bottle - in particular a bottle closure - consisting of a cap with internal thread, connected to this a snap-on, limited to the cap cap rotatably mounted about the axial axis and sealed against this by a flat gasket cap with a hollow cylindrical neck, which receives the mouthpiece , And forms the discharge opening together with the hollow-cylindrical, in-bottle-facing approach of the cap. In addition, the cap has a molded, outwardly facing holder with hinge shaft for receiving the hinge pin of a rotatably mounted and - relative to the joint - latching in the cap, approximately hemispherical lid, the only in the drinking rotational position 'open' of cap and cap can be opened. In front of the 'open' position there is a 'venting' rotational position in which a venting channel is exposed from the closure cap, via the flat gasket, via an annular groove of the mouthpiece and a radial bore in the neck of the cap for the purpose of producing cylinders under internal pressure Vent the opening with the lid still closed - without spraying.
The handling of the bottle or closure does not provide any intermediate positions during opening in addition to the 'up' / 'to' position.

The European patent application EP 461,065 / Swiss registration CH 19 36/90 represents a closure for a bottle before with a mouthpiece, which is arranged axially displaceably in the hollow cylindrical screw member and closed in the inserted state by a pin attached to the screw. A laterally outside the mouthpiece in the screw mounted ventilation channel, which is closed by a mouthpiece molded, projecting into the ventilation duct dome, allows the access of air to the interior of the bottle and prevents the formation of a negative pressure within the bottle.
The axial displacement of the mouthpiece in the screw allows no intermediate positions except 'open' or 'closed'.

The German patent DE 44 95 238 / Swiss registration CH 687 074 / international registration W01995 / 003 227 discloses a cap for a bottle or a bidon, which ensures a secure pressure equalization in the bottle even with continuous liquid withdrawal, without having to accept a leakage. The closure consists of a lid part with a central, axial, stationary guide pin which is formed towards the bottle as a poppet valve, and a coaxially arranged axially displaceable, designed as a mouthpiece at the free end hollow cylindrical plunger, which forms an annular channel with the guide pin the escaping bottle or bidonine content. In the plunger sits a circular seal, which cooperates as a valve seat with the poppet valve. Outside the plunger there is a separate air flow path for pressure equalization in which additional valve means operable by the plunger are arranged.
The valve controls of bottle contents and air are carried out via the same plunger and have only the operating states 'open' and 'closed'.

The Swiss patent CH 686 244 / German utility model DE 93 11 815 is the cap of the bottle from patent CH 684 639 / ..., consisting of a bottle body, a cap screwed onto the bottle neck, a mouthpiece axially movable in the cap by screw rotation and possibly a hinged cover protecting the mouthpiece, complemented by a non-return valve constructed of food grade elastomer such as silicone rubber opens at bottle vacuum and degrades this, but prevents the reduction of a cylinder overpressure by carefully opening the ventilation ducts.
Overpressure can only be reduced by opening the drinking channel; Targeted drinking volumes can not be adjusted.

The German utility model DE 93 10 432 discloses a dispenser for pourable goods - such as tablets, dragees, capsules or the like - consisting of a base plate with a tubular approach - pronounced as Behälterhalspassung - and rotatably mounted on the base plate centrally arranged dial plate, wherein the base plate and dial, each with at least one eccentrically arranged Recess are provided and the recesses have the same distance from the axis of rotation. The recesses may be circular and formed with the same cross-section. The base plate can be formed with one and the dial with a plurality of recesses of different cross sections; the respective removal setting of the base plate and dial is fixed by engaging in corresponding recesses of the base plate locking cam of the dial.
A targeted occasional container removal is not possible with the arrangement.

According to the Swiss patent CH 684 639 / German utility model DE 93 03 734 / French utility model FR 2 689 102 a drinking bottle is presented consisting of a bottle body, a cap screwed onto the neck of the bottle, a mouthpiece which is axially movable in the cap by screw rotation, and possibly a hinged cover protecting the mouthpiece. Is sealed between the bottle neck and cap with a flat gasket, between the ventilation channels of the cap and the mouthpiece also by a flat gasket and between the drinking channel of the cap and the mouthpiece by means of an O-ring. Since structurally open the ventilation ducts earlier than the drinking channel, it should be achieved that an existing differential pressure in the bottle is compensated without damaging the user. A possible leakage through the ventilation ducts is not prevented, a targeted adjustability of the volume flow through the drinking channel is not given.

The German disclosure DE 43 03 668 describes a closure for sports and travel water bottles, which consists of a screwed into the bottle hollow cylindrical body with radially arranged ventilation holes and centrally molded in the axial direction outwardly funnel-shaped opening mouth piece, which is connected to the bottle contents in the interior by a spout and a riser is, exists and has a molded on a film hinge pot-shaped cap, which - folded over the body - with an inner ring jacket the Venting and with a - molded in the cap lid plug - the funnel-shaped mouthpiece closes.
The designed drinking bottle knows only the two states with closed or opened cap.

According to the American patent US 5 509 551 a replacement bottle cap for a standardized beverage packaging is presented. The bottle cap consists of a screw cap with mounting straps for a strap, has an integrated drinking straw or integrated connecting piece for receiving a drinking straw to the outside and inside the bottle and a ventilation device with an adjustable in the axial direction closure element. In a further embodiment, the cover receives a geometrically adapted rotatably mounted functional plate with a 'up' and 'to' position for the tight closure of the removal opening.
Neglecting linguistic and graphic defects, the lid assembly does not provide a metered removal.

The American patent US 5,294,014 presents a closure arrangement for containers - in particular for a drinking cup with a larger capacity - with a rotatable in the horizontal plane shutter disc having a side lever, whereby a one-handed operation is possible. The closure assembly is further characterized by a liquid-tight and airtight closure, but can be easily operated by the user. The locking device consists of a housing with a spout for liquid or flowable material from the container and a centrally mounted on the housing rotary member with a sealing means which seals the spout in the closed position. A pressure medium, which reacts upon rotation of the closure disc, generates a force perpendicular to the sealant and the spout absolutely seals.
The closing arrangement has a lever-operated two-position closure, wherein in the final closing position additionally a locking cam acts on the spout.

With the German disclosure DE 18 16 709 a closure for a particular plastic container is presented, in which initially a first lid with an eccentrically mounted filling / emptying opening with its protruding edge is non-rotatably attached to the container edge by latching the circumferential annular bead latching. Over the first, a second lid is slipped with an eccentrically mounted filling / emptying opening, the protruding edge with its inner side, which has a circumferential rib, a projecting lip of the first cover, and forms a movable bearing with this. By turning the second lid against the first lid, the two eccentric lid openings for container filling or emptying can be contrasted.
About the tightness of the closure device no statement is made.

The German patent DE 65 85 62 / Swiss script CH 19 94 08 represent a flask with a screwed closure, consisting of a closure head and a displaceable in the axial direction and under spring pressure cap - with extending in the axial direction drinking tube with the inward sliding exposing openings and within the drinking tube also extending in the axial direction of the air tube with radial lateral connection - so that with slight pressure on the cap in the direction of the bottle body, the inflow openings exposed within the bottle and at the same time the axial outlet of the air tube to the outside world. For the purpose of more convenient drinking and filling of the bottle, the cap can be rotatably locked in this state by double bayonet closure.
Although the closure made of metallic materials theoretically allows withdrawals controlled by differentiated axial displacement, the double bayonet closure permits only the up and the closed position.

The German patent DE 4 66 92 describes a bottle closure consisting of a bottle head flush terminating centric axially pierced Korkpfropfen, on the side facing away from the bottle arranged on the bore closure means of three superimposed, with the bottle top edge final circular discs wearing, the diameter of the middle shutter disc is slightly larger than that Radius of the other two discs is, the closure disc is eccentrically rotatably arranged via a guide pin of the first inner disc, can be rotated via a further driving pin of the third outer disc and a valve to the effect forms that through the rotation of an asymmetrically arranged flow bore with the center Through holes of the first and the third disc and the plug hole can be reconciled and establishes the open closure state.
By turning the third disc in each case until the driving pin strikes a slot end - the 'open' or 'closed' position is set; a drinking straw function is not provided.

All publications presented are only partially or not at all for the specific use as a bottle cap for a drink bottle for drinks storage for school, sports, travel and leisure - especially not as a closure for a children's bottle for drinks storage for school, sports, travel and leisure with automatic valve reset function.

The invention is therefore based on the object, a device according to the preamble of claim 1, a bottle closure for a bottle for storing drinks for school, sports, travel and leisure - especially a closure for a children's bottle for storing drinks for school, sports, travel and leisure with automatic valve reset function.

This object is achieved by the characterizing features of claim 1; to advantageous embodiments, the dependent claims. The bottle according to the inventive novelty preferably consists of a hollow cylindrical metal bottle body - a plastic bottle is expressly not excluded - with a plastic external thread on the bottle neck, with a cylindrical bottle closure with internal thread is in a detachable connection, which consists of a screw cap which receives a rotatably mounted mouthpiece rotary closure via a further seal, which also has a diametrically opposite molded stopper with operating function, so that the bottle also with one hand - the bottle with one hand and with your thumb, suitable for right and left handed - is open.

A further embodiment of the invention provides that the bottle body of the bottle is preferably made of aluminum with an inwardly curved bottle bottom. Towards the bottleneck, the bottle body tapers in the form of a spherical cap to form a hollow-cylindrical projection which ends with a narrow boundary bent at right angles outwards. The approach is wearer of a molded, rotatably seated plastic ring, provided with an external thread, which ends at the lower stop of the plastic ring. The bottle is coated inside absolutely smooth surface and outside painted (not shown).

A further embodiment of the invention provides that the drinking bottle closure consists of a screw cap, a mouthpiece rotary closure and a pivot cap (optional). The mechanical interface to the bottle body is the external thread on the bottle neck or the internal thread of the screw cap of the bottle cap.

• am Schraubende des Innengewindes befindet sich eine ausgeprägte Nut zur Aufnahme einer Rund- oder Flachdichtung
• am Schraubende des Flaschen-Außengewindes befindet sich ein unverlierbar gelagerter Dicht-/O-Ring
• Flaschen-Außen- und/oder Schraubkappen-Innengewinde besitzen eine im 2K (Komponenten)-Spritzverfahren angebrachte Elastomer-Dichtlippe.

Der Deckel der Schraubkappe zeichnet sich durch zwei spiegelsymmetrisch gegenüberliegende ebene, in radialer Richtung begrenzte Aussparungen aus, die später die Rückstellfedern des Mundstück-Drehverschlusses flächenbündig aufnehmen. Die hohlzylinderförmige Seitenwand des inneren Ansatzes - des Dichtzylinders - weist in bestimmter Lage und in ausgewählter Geometrie Durchbrüche auf, die mit geeigneten Durchbrüchen eines zylinderförmigen Ansatzes des Mundstück-Drehverschlusses den Trinkkanal bilden, wenn die Durchbrüche durch Drehbewegung mindestens teilweise in Deckung gebracht werden. An seinem zum Flaschenkörper hin gerichteten Ende verjüngt sich der Dichtzylinder zu einem Führungszylinder zwecks Aufnahme des Mundstück-Drehverschlusses.The cup-shaped pronounced screw cap has a two-shell running, cylindrical side wall, the outer shell forms the handle surface and by ribs and recessed grips (not shown) is identified, also opposite two recesses - each with recessed grip - in the hollow cylindrical outer shell has, later pick up the operating unit of the mouthpiece screw cap. Towards the center, the screw cap has another hollow-cylindrical, open in the center approach that gives the screw cap overall the appearance of a cake shape open to the bottle body - the sealing cylinder. The outer shell is internally provided with a multi-start thread, which corresponds to the external thread of the bottle body for receiving the screw cap. The production of the tightness of this releasable connection can be done in various ways

• At the screw end of the internal thread is a pronounced groove for receiving a round or flat gasket
• At the screw end of the bottle external thread there is a captive mounted sealing / O-ring
• Bottle external and / or screw cap internal threads have a 2K (component) injection molded elastomer sealing lip.

The lid of the screw cap is characterized by two mirror-symmetrically opposite flat, limited in the radial direction recesses, which later receive the return springs of the mouthpiece screw cap flush. The hollow cylindrical side wall of the inner approach - the sealing cylinder - has breakthroughs in a certain position and in selected geometry, which form the drinking channel with suitable breakthroughs of a cylindrical neck of the mouthpiece screw cap when the openings by rotational movement at least be partially covered. At its end directed towards the bottle body, the sealing cylinder tapers to form a guide cylinder for receiving the mouthpiece rotary closure.

In a further advantageous embodiment of the inventive novelty, the screw cap with the mouthpiece rotary closure forms the water bottle valve, which images several operating states by rotational positions. For this purpose, the screw cap has on its upper side - the lid surface - a tubular bottle-body facing two-stage approach - sealing and guide cylinder - whose inner cylinder wall is the guide for the mouthpiece rotary closure and receives the sealing cylinder. The mouthpiece rotary closure is pronounced as a circular plate whose top forms a trained oval mouthpiece with an axially extending through hole for the drinking channel and a Beipaß - also in the axial direction - as a vent channel, the underside fits flush into the screw cap surface thereby in that the return springs find space in the recesses of the screw cap lid surface provided for this purpose and the sealing cylinder of the mouthpiece screw cap fits into the sealing and guiding cylinders of the screw cap. At the plate-shaped edge of the mouthpiece screw cap are located in the axial direction of two control units diametrically opposite, which engage in lateral recesses of the outer shell of the screw cap. Furthermore, the cup-shaped sealing cylinder of the mouthpiece rotary closure has in the axial direction outwardly facing latching hooks which engage rotatably at the bottom of the guide cylinder of the screw cap. Recesses, operating units, return springs, latching hooks and openings of the screw cap and mouthpiece rotary closure must be matched in their geometry, their sequence of motion and their effects on each other.
By pressing the latching hooks in the direction of the center and by gently pushing up, the screw cap and the mouthpiece twist-lock are disconnected, as for cleaning purposes; the assembly takes place in reverse order, with the assembly on the relaxed position of the return springs in the recesses must be taken (for non-fitted springs there is no flush between mouthpiece and screw cap and the locking hooks do not reach under the edge of the guide cylinder). The possible angle of rotation between mouthpiece and screw cap is about 30 °; it can be done by hand or by mouth. During rotation against the force of the return springs, the small outlet bore for the degassing and overpressure channel is first reached; in this position, the gas / pressure is discharged through the mouthpiece, but it is also possible to provide for a separate channel to the outside (not shown).

Furthermore, the gas / pressure passes uncontrolled from the mouthpiece; In a further advantageous embodiment of the development, the mouthpiece (and / the emerging gas / pressure) is collected by a pivot cap which is pivotally mounted on the mouthpiece and rotatably guided on the opposite side by means of a cap-latching hook under an undercut locking projection of the screw cap is released and only after reaching the gas / overpressure channel for pivoting (not shown). Gas / overpressure arises on the one hand by the filled liquid - as enriched with carbonic acid - and on the other hand by the use of the bottle in different air pressure altitudes - as with hang gliding, or similar. By further rotation of the mouthpiece until it stops - operating units on the stop of the recesses of the Au βenhülle - the openings of the sealing cylinder of the screw cap and mouthpiece are brought to cover, the drinking channel is released for use; while it is being drunk, a vent and pressure equalization channel prevents the formation of negative pressure in the bottle.

The through hole of the mouthpiece is intended for drinking straw operation; the breakthrough of the sealing cylinder of the screw cap is supplemented by a pointing into the bottle interior, a drinking straw extension receiving 90 ° elbow (not shown)

During rotation of the mouthpiece or hinged with the mouthpiece swing cap from the rest position - rotational position 1 - against the screw, the return springs of the mouthpiece in the recesses of the lid of the screw cap, the resistance increases with increasing rotation angle, about the rotational position. 2 - Relieve gas / overpressure, until the stop of the operating unit of the mouthpiece on the recess of the outer shell of the screw cap - the pivot cap can be opened (the latching hook is outside the locking projection), the openings are in cover, the drinking channel is open - rotational position If the apertures are given a rotation angle-dependent geometry, the extraction volume is also dependent on the angle of rotation (not shown); such as e.g. viscose-dependent liquids are dosed out of the bottle. After the drinking process, the mouthpiece springs back into its sealing rest position. When operating with swivel cap, the swivel cap is closed over the mouthpiece after drinking, so that when springing back the locking hook of the swivel cap under the locking projection of the screw rotates and locking engages (not shown). When idle, the drinking and venting channels are tightly closed.

A further embodiment of the invention provides that the pivot cap is designed approximately hemispherical, with a screen as a handle edge, as a receptacle for drinking straws and operating instruction 'open' / 'close', and latched on the cap hinge with the mouthpiece rotary shutter hinged connected. The swivel cap is provided on both sides with recessed grips, which have grip strips for better grip when twisting in a horizontal plane. In addition, a forefinger recess for the ergonomic 3-finger grip is provided. On the rear side of the index finger well, a vertical web is mounted with a latching hook, which is locked in the closed state of the pivot cap by latching projection (not shown).

Starting from a closed bottle - turning position 1, access to the mouthpiece always takes place over the rotation of the pivot cap in the 'open' direction, either until the pivot cap open or twisting until it stops - rotational position 3 - maximum flow, opening for drinking straws. In the transition from the rotational position 1 'closed' in the rotational position 3 'open', the state 'vent pressure / venting' run over; in this rotational position 2, the pivot cap can not be opened. The torsional force exerted on the swivel cap is transmitted via the cap hinge to the mouthpiece swivel lock, which always moves in the same direction as the swivel cap in the direction of rotation - with the screw cap fixed (screwed tight to the bottle body).

Der Deckel 1 51 der Schraubkappe 5 zeichnet sich durch zwei spiegelsymmetrisch gegenüberliegende ebene, in radialer Richtung begrenzte Aussparungen 1 , 2 53 , 54 aus, die später die Rückstellfedern 27 des Mundstück-Drehverschlusses 2 flächenbündig aufnehmen. Die hohlzylinderförmige Seitenwand des inneren Ansatzes - des Dichtzylinders 59 - weist in bestimmter Lage und in ausgewählter Geometrie Durchbrüche 60 auf, die mit geeigneten Durchbrüchen 29 , 30 eines zylinderförmigen Ansatzes 28 des Mundstück-Drehverschlusses 2 den Trinkkanal 30 , 60 bilden, wenn die Durchbrüche durch Drehbewegung mindestens teilweise in Deckung gebracht werden. An seinem zum Flaschenkörper hin gerichteten Ende verjüngt sich der Dichtzylinder 59 der Schraubkappe 5 zu einem Führungszylinder 61 zwecks Aufnahme des Dichtzylinders 28 des Mundstück-Drehverschlusses 2 .The cup-shaped screw cap 5 - Fig. 2 a) and b) has a clamshell running, cylindrical side wall, the outer shell 55 forms the handle surface and by ribs and recessed grips (not shown) is identified, further opposite two recesses 3 57 - each with recessed grip 58 provided - in the hollow cylindrical outer shell has, later receive the operating unit 25 of the mouthpiece screw cap 2. Towards the center, the screw cap 5 has another hollow-cylindrical, open in the center approach that gives the screw cap overall the appearance of a cake shape open to the bottle body - the sealing cylinder 59th The outer shell is internally provided with a multi-start thread 63, which corresponds to the external thread of the bottle body for receiving the screw cap. The production of the tightness of this releasable connection can be varied (not shown)

• at the screw end of the internal thread 63 is a pronounced groove for receiving a round or flat gasket
• At the screw end of the bottle external thread there is a captive mounted sealing / O-ring
• Bottle external and / or screw cap internal threads 63 have a 2K (component) injection molded elastomer sealing lip.

The lid 1 51 of the screw cap 5 is characterized by two mirror-symmetrically opposite planar, limited in the radial direction recesses 1, 2 53, 54, which later receive the return springs 27 of the mouthpiece rotary closure 2 flush. The hollow cylindrical side wall of the inner approach - the sealing cylinder 59 - has openings 60 in a certain position and in selected geometry, which form the drinking channel 30, 60 with suitable openings 29, 30 of a cylindrical projection 28 of the mouthpiece rotary closure 2, when the openings through Rotational motion are at least partially brought into line. At its end directed towards the bottle body, the sealing cylinder 59 of the screw cap 5 tapers to form a guide cylinder 61 for receiving the sealing cylinder 28 of the mouthpiece rotary closure 2.

The screw cap 5 forms with the mouthpiece rotary closure 2, the water bottle valve 3 a) and b) and 4 a) and b) , which depicts several operating states through rotational positions. For this purpose, the screw cap has on its upper side - the lid surface 1 51 - a tubular bottle-body facing two-stage approach - sealing 59 and guide cylinder 61 - whose inner cylinder wall is the guide for the mouthpiece rotary closure 2 and the sealing cylinder 28 receives. The mouthpiece rotary closure is pronounced as a circular plate 23, the top of which is a trained oval mouthpiece 21 with a running in the axial direction through hole 22 for the drinking channel 30 and a Beipaß - also in the axial direction - as a vent channel 35, the underside of which fits flush into the screw cap surface 51, 52 characterized in that the return springs 27 place in the for provided recesses 1, 2 53, 54 of the screw cap cover surface 51, 52 find and the sealing cylinder 28 of the mouthpiece rotary closure 2 fits into sealing 59 and guide cylinder 61 of the screw cap 5. On the plate-shaped edge 24 of the mouthpiece rotary closure 2 are located in the axial direction two control units 25 diametrically opposite, which engage in lateral recesses 3 57 of the outer shell 55 of the screw cap 5. Furthermore, the cup-shaped sealing cylinder 28 of the mouthpiece rotary closure 2 has in the axial direction outwardly facing latching hooks 33 which engage rotatably at the lower edge of the guide cylinder 61 of the screw cap 5. Recesses, operating units, return springs, latching hooks and openings of the screw cap and mouthpiece rotary closure must be matched in their geometry, their sequence of motion and their effects on each other.

By pressing the release lever 34 of the latch hooks 33 in the radial direction to the axis connected with a slight push - Fig. 1 c) , screw cap 5 and mouthpiece twist-lock 2 are separated - as for cleaning purposes -; the assembly takes place in reverse order, with the assembly on the relaxed position of the return springs 27 in the recesses 1, 2 53, 54 must be respected (with non-fitted springs there is no flush between mouthpiece 2 and screw cap 5 and the latching hooks 33 do not fall the edge of the guide cylinder 61). The possible angle of rotation between mouthpiece 2 and screw cap 5 is about 30 °; it can be done by hand or by mouth. During rotation against the force of the return springs 27, the small outlet hole for the gas and pressure channel 29 is reached first; in this position, the gas / pressure is discharged through the mouthpiece 22, but it is also possible to provide for a separate channel to the outside (not shown).

Furthermore, the gas / excess pressure exits uncontrolled from the mouthpiece 22, Fig. 3 a) ; the mouthpiece (and / the escaping gas / pressure) is covered by a pivot cap 8, which is pivotally mounted on the edge 24 of the mouthpiece and on the. opposite side by means of a cap-latching hook under an undercut locking projection of the screw cap 5 is rotatably guided and is released only after reaching the gas / overpressure channel 29 by turning to swing open (not shown). Gas / overpressure arises on the one hand by the filled liquid - as enriched with carbon dioxide - and on the other hand by the use of the bottle in different air pressure altitudes - such as hang gliding, or similar. By further rotation of the mouthpiece until it stops - operating units 25 at the stop of the recesses 3 57 of the Au βenhülle 55 - the openings 30, 60 of the sealing cylinder 28, 59 of mouthpiece 2 and screw cap 5 brought to cover, the drinking channel 22, 30 60 is released for use; while drinking prevents a vent and Pressure equalization channel 35 of the mouthpiece screw cap 2, the formation of negative pressure in the bottle.

The through-bore 22 of the mouthpiece 21 is intended for drinking straw operation - Fig. 2 b) ; the opening 60 of the sealing cylinder 59 of the screw cap 5 is supplemented by a pointing into the bottle interior, a Trinkhalmverlängerung receiving 90 ° elbow (not shown)

During the rotation of the mouthpiece 21 or possibly hinged with the mouthpiece pivot cap 8 from the rest position - rotational position 1 - against the screw cap 5 - Fig. 5 a) and b) , the return springs 27 of the mouthpiece 21 in the recesses 1, 2 53, 54 of the lid 1 51 of the screw on the screw, the resistance increases with increasing rotation angle, on the rotational position 2 - Relieve gas / pressure until it stops the control units 25 of the mouthpiece 21 on the recess 3 57 of the outer shell 55 of the screw cap - the pivot cap 8 can be opened (the latching hook is located outside the latching projection), the openings 30, 60 are in cover, the drinking channel 22, 30, 60 is open - 3. If the apertures 30, 60 are given a rotation angle-dependent geometry, the extraction volume is also dependent on the angle of rotation (not shown); For example, viscose-dependent liquids can be dispensed in doses from the bottle. After the drinking process, the mouthpiece 21 springs back into its sealing rest position. When operating with swivel cap 8, the swivel cap is closed over the mouthpiece 21 after drinking, so that when springing back the locking hook of the swivel cap under the locking projection of the screw cap 5 engages rotating and locking (not shown). At rest, the drinking 22, 30, 60 and the venting channel 35 are tightly closed.
