The substantially cylindrical bottle body is adapted depending on the application - either smooth hollow cylindrical body z. For example, 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 mounting area for a rod attachment and a grip - not too soft - for one-handed operation. At the top of the bottle with filling 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 cap 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 drinks storage for school, sport, travel and leisure - especially closures of children's bottles for drinks 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 drinks storage for school, sports, travel and leisure - especially of 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 application US 2009 277 907 / Canadian application CA 2 610 734 / international registration WO2006 / 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 pipe socket and centrally located, outer side valve element, the outer pipe socket a centrally perforated pot-shaped, arranged to be movable in the axial direction 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 cap - before, 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 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. Before the position 'open' there is a rotary position 'venting' in which a vent channel from the cap, the flat gasket, an annular groove of the mouthpiece and a radial bore in the base of the cap is disclosed for the purpose of being under internal pressure Vent the bottles with the lid still open before opening them - 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 duct, which is closed by a mouthpiece molded on, projecting into the ventilation duct dome, allows access from the air to the inside of the bottle and prevents the formation of a negative pressure inside 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 WO1995 / 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 via a film hinge cup-shaped cap, which - folded over the body - with an inner ring jacket the vents and with a - molded in the cap lid plug - closes the funnel-shaped mouthpiece.

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 fastening straps for a carrying 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 lid receives a geometrically adapted rotatably mounted functional plate with an "open" - and "closed" 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 spring pressure cap - with extending in the axial direction drinking tube with Einwärtsschieben exposing inflow and within the drinking tube also extending in the axial direction air tube with radial lateral connection - exists, so that with slight pressure on the cap in the direction of the bottle body, the inflow openings are exposed within the bottle and at the same time the axial outlet of the air tube to the outside world as well. 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 drinking bottle for drinks storage for school, sports, travel and leisure - in particular to provide a closure for a children's bottle for drinks storage 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 drinking 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, which is in a detachable connection with a cylindrical bottle closure with internal thread, 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 one-handed - the bottle with one hand and with the thumb, suitable for right and left-handers - to 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.

The cup-shaped pronounced screw cap has a two-shell running, cylindrical side wall, wherein the outer shell forms the handle surface and by ribs and recessed grips (not shown) is identified, further 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 is a captive mounted sealing / O-ring
• - Bottle external and / or screw cap internal thread have a 2K (component) spray-applied 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 are at least partially brought into coincidence by rotational movement. 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 Rotary closure are diametrically opposed in the axial direction two control units, 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 carbon dioxide - and on the other hand by the use of the bottle in different air pressure altitudes - such as hang gliding, o. Ä. By further rotation of the mouthpiece until it stops - operating units at the stop of Recesses of the outer shell - are brought through the openings of the sealing cylinder of the screw cap and mouthpiece 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 complemented by a pointing into the bottle interior, a Trinkhalmverlängerung 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 cap, 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 of the second - 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 locking hook is outside the locking projection), the openings are in cover, the drinking channel is open - 3 rotation If the apertures are given a rotation angle-dependent geometry, the extraction volume is also dependent on the angle of rotation (not shown); so z. B. viscose-dependent liquids metered from 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).

• - Bottle external and / or screw cap internal thread 63 have a 2K (component) injection molded elastomer sealing lip.

The lid 1 51 the screw cap 5 is characterized by two mirror-symmetrically opposed planar, limited in the radial direction recesses 1, 2nd 53 . 54 out, which later the return springs 27 of the mouthpiece screw cap 2 flush with the surface. The hollow cylindrical side wall of the inner approach - the sealing cylinder 59 - has breakthroughs in a specific position and in selected geometry 60 on that with suitable breakthroughs 29 . 30 a cylindrical approach 28 of the mouthpiece screw cap 2 the drinking channel 30 . 60 form when the openings are at least partially brought into coincidence by rotational movement. At its end directed towards the bottle body, the sealing cylinder tapers 59 the screw cap 5 to a guide cylinder 61 for receiving the sealing cylinder 28 of the mouthpiece screw cap 2 ,

The screw cap 5 forms with the mouthpiece twist lock 2 the water bottle valve 3a) and b) and 4a) and b), which depicts several operating states by rotational positions. For this purpose has the screw cap on its top - the lid surface. 1 51 A tubular two-step approach to the bottle body, sealing 59 and guide cylinder 61 - The inner cylinder wall, the guide for the mouthpiece rotary closure 2 represents and its sealing cylinder 28 receives. The mouthpiece twist lock is as a circular dish 23 pronounced, the top of a trained oval mouthpiece 21 with a through hole extending in the axial direction 22 for the drinking channel 30 and a Beipaß - also in the axial direction - as a venting channel 35 forms, the bottom of which is flush in the screw cap surface 51 . 52 characterized in that the return springs 27 Place in the designated recesses 1, 2 53 . 54 the screw cap surface 51 . 52 find and the sealing cylinder 28 of the mouthpiece screw cap 2 in sealing 59 and guide cylinder 61 the screw cap 5 fits.
