Abstract

The invention relates to a container closure (1) comprising a cap (2) that can be applied to a container opening, a pouring element (20) arranged on the cap (2), an outlet tube (21), and a closing device that can close the outlet channel (22) of the outlet tube (21). Said closing device comprises a closing element (40) that is positioned on a sealing surface (8) arranged on the inlet (23) of the outlet channel (22) in the closing position, and can be displaced in the axial direction of the outlet tube (21), from a closing position to an opening position and vice versa, by means of an actuating element. The aim of the invention is to ensure a tight closure even when the pressure inside the container is high, and to be able to easily open the container closure. To this end, the actuating element is a pintail (30) that is arranged at a right angle to the longitudinal axis of the outlet tube (21) and is mounted in such a way that it can rotate therein (20).

Description

The invention relates to a container closure, in particular a closure for drinking bottles, with a mountable on a container opening cap, a cap disposed on the spout with an outlet and with a outlet of the outlet tube closable closure device having a closure element, which in the closed position at a formed in the axial direction of the outlet tube by means of an actuating element, which is arranged as a right angle to the longitudinal axis of the outlet, rotatably mounted in the spout pivot pin, which has within the outlet tube to its axis of rotation eccentric portion formed from a closing in an open position and vice versa is movable.

In the case of container closures, which are generally used for drinking bottles in the sports sector, the closure device can be actuated by hand and, in the closed position, ensures a liquid-tight closure of the container contents.

If necessary, the closure device can be moved in by hand Open position can be brought, so that without the container closure must be removed, the liquid contained in the container can be removed.

A widely used container closure has an outlet tube, at the upper end of which a smaller diameter disc is arranged, leaving an annular gap. A cap provided with an opening corresponding to the diameter of the disc is arranged via the outlet tube. This closure cap is displaceable in the axial direction of the outlet tube,
wherein the cap in the open position releases the annular gap between the outlet tube and the smaller-diameter disc and covers this annular gap in the closed position. However, this per se practical one-hand condition of the closure has the disadvantage that these container closures can only be used for drinking bottles that contain carbonated drinks. With an increase in the internal pressure in the container, the cap is inevitably pressed in the open position with the result that the container contents may leak unintentionally.

From the JP 2003 144 338 is a generic container closure known. The pivot pin in this case has an eccentric portion which rolls on actuation on the shaft end of the plunger-like closure element, whereby this is inserted axially into the container. This creates a gap between the valve plate of the closure element and the corresponding sealing surface at the inlet opening of the outlet channel. A disadvantage of this container closure is that the closure element can only be transferred back into its closed position by support by a spring or due to a gas pressure in the container interior. The former option is mechanically complex and therefore expensive; the latter, especially in the case of low-carbon or low-residue content of the container, is slow and unreliable.

From the JP 09 188 352 a similar container closure is known in which, however, the pivot pin and the closure element are operatively connected via a further, movable contact member on which the eccentric part of the pivot pin rolls and which in turn rolls on the shaft end of the closure element.

From the DE 199 38 220 A1 a valve head for placement on beverage bottles is known, which has a foldable actuating lever, which is supported at one of its two ends in the wall of the valve head and is pivotally mounted there. On the actuating lever, a rod is attached with a valve plug which presses against a valve seat during upward movement. Above the valve seat opens an obliquely downwardly extending outlet pipe in the valve head, from which, however, is not possible because of its inclination a liquid removal, especially in the overhead position of the bottle. In order to keep the valve plug in the closed position, a pressure-elastic means is provided, which is formed by a set of elongated elements. Arrangement and design of these elastic elements can not ensure a consistent closing force in the long run, so that leaks occur at this point. Also, the operating lever can be inadvertently pressed in the open position when the filled bottle is transported together with other items, eg in a sports bag. Another leaking point may be the sliding guide for the valve stem, in particular when, when opening, a pressurized carbonated liquid shoots upwards and strikes the sliding guide before it is deflected into the outlet tube. In the case of the smallest dimensional errors of the individual components or dimensional changes due to thermal effects, leaks may occur. The known valve head is therefore not suitable for the production of mass products.

The WO 03/05758 A1 describes a closable dispenser with a spout and a closure device. The spout has at the bottom of a transverse to the neck of the bottle recess into which a rotatable pin is inserted, which is provided with an actuating lever. The bolt has a passage opening, which can be brought by opening the bolt in the open and closed positions. It is shown to be advantageous if the between the closure device and the lying inside the bottle part of the spout, so the lower portion of the closure device receiving recess of the spout is at least partially elastic and can be pressed by a pressure present in the container elastically against the closure device , It is further noted that the rotation of the closure device can be accomplished even if in the bottle Overpressure or negative pressure prevails. The force exerted on the closure device by a positive or negative pressure prevailing in the bottle does not act in the direction in which the closure device has to be moved in order to bring it from the closed position into the open position and vice versa. A disadvantage of this closure device, however, is that the pivot pin must be precisely fitted and must rest without play in the spout to avoid leakage of high pressure fluid.

The WO 03/057588 A1 describes a dispensing device with a sealing plate, which is arranged in the interior of a screw cap and presses in the closed position from below against the inlet opening of the outlet channel, so that an overpressure in the container interior automatically contributes to a tight seal. The sealing plate is actuated by a cap which extends across the outlet channel and which has a cup-shaped connecting part extending into the outlet channel. The sealing plate is fixed by means of a pin-like plug at the bottom of the connecting part. By axial displacement of the cap, the sealing plate is moved from opening to closed position and vice versa. Although a pressure equalization channel is provided, can be reduced by the overpressure when opening, large forces are required to open against the pressure prevailing in the container, which could cause the user to eventually hit the cap, so that the pressure can explode explosively ,

In the WO document 03/057588 A1 will be another one Embodiment described, which has a screw cap, so that the power transmission to the sealing plate can be done continuously. The sealing plate is attached by means of a separate pin to the cap, which has the disadvantage that the sealing plate must have an opening through which the pin is inserted. As a result, leaks can occur, especially if incorrect operations occur. The closure takes some getting used to and may be misused in that further screwing the cap against the usual functions of screw caps "opening" and unscrewing the cap means "closing". An opened lock can be inadvertently opened by further unscrewing.

Starting from the JP 2003 144 338 It is the object of the invention to provide a container closure, which ensures a tight seal regardless of an internal pressure prevailing in the container and can be opened and closed in a simple manner.

This object is achieved in conjunction with the features of the preamble of claim 1, characterized in that the closure element comprises an annular connecting element which engages around the eccentric portion of the pivot pin, so that the pivot pin is articulated to the connecting element.

The closure element is articulated via a connecting rod or crankshaft-like connection to the pivot pin, so that the rotational movement of the pivot pin in a lifting movement the closure element can be implemented. It is thus possible in a simple manner and with comparatively little effort, by turning the actuating element to move the closure element to open against the internal pressure inwards. On the other hand, when closing, the closure element is also actively brought to the sealing surface, independently of the internal pressure, by turning the pivot pin.

The pintle does not have to be fitted exactly because it does not perform any sealing function itself.

The cap and pivot preferably have a common longitudinal axis, i. the spout part with the outlet pipe extends vertically upwards, so that liquid can be removed from the container in the overhead position of the container when the container closure is screwed on. The pintle is located in the outlet of the outlet pipe and is in the open position during the removal of liquid from this lapped.

The annular connecting element preferably has an opening that is elongated perpendicular to the longitudinal axis of the outlet tube. In contrast to a circular opening, the advantage is that, when the pivot pin is turned, the eccentric part can freely rotate without the latching element making a rocking motion, which would lead to leaks in the closure element. It is thereby ensured a controlled vertical movement of the closure element.

In order to operate the pintle by hand, this extends at least on one side through the wall of the outlet tube to the outside and there has a corresponding grip element. The handle member and / or the pivot pin may have suitable locking elements to indicate the user closing and opening position during actuation.

The gripping element may have at its free end a plate-shaped element which, in the closed position, covers the outlet opening in order to provide protection against contamination of the outlet tube. This arranged perpendicular to the handle element cover plate may be formed, for example. The handle element and / or the cover plate can have additional ribs on their outer sides, on the one hand to facilitate the operation and on the other hand to prevent the user from opening the closure with his mouth.

In the outlet pipe, an intermediate bottom with an opening is preferably arranged above the pivot pin. In the closed position, the annular connecting element engages in this opening and closes it. As a result, an additional seal is achieved, which prevents an explosive discharge of the optionally pressurized container liquid during the opening process.

In this context, it is advantageous if the spout part preferably has at least one pressure relief opening, which is preferably in the Wall of the spout between pivot pin and closure element is arranged.

At the beginning of the opening process, when the opening in the false bottom is still closed, the overpressure can first escape through the pressure relief opening (s) without allowing gas or liquid to enter the outlet pipe.

Preferably, the pressure relief opening has a conically widening outward shape.

In an alternative embodiment, a container closure is provided, which is characterized in that the actuating element is a rotary cap mounted on the outer tube, which has a threaded tube in the interior of the outlet tube, and in that the closure element has a threaded pin extending into the spout part, which engages in the threaded tube ,

Also in this variant, a rotational movement of the actuating element in a lifting movement of the Closure element implemented. The effort is also correspondingly low when the closure element is to be opened against a high internal pressure.

The rotary cap is preferably fixed in the axial direction, so that the rotational movement is completely converted into a lifting movement of the closure element. The container closure has the advantage that the container closure is closed by "turning to the right" and is opened by "turning to the left".

The threaded tube has at least one opening in order to allow in the open position of the closure element, an outlet of the liquid from the container from the inner tube into the threaded tube and thus a pouring.

In this embodiment, the threaded pin can be designed such that it closes this opening upon reaching the closed position of the closure element. This embodiment may also have at least one pressure relief opening.

The closure element, which is used in both embodiments, preferably has a first conical surface with the cone angle α ₁ , which merges in the direction of outlet tube in a second conical surface with the cone angle α ₂ , wherein for the cone angle α ₁ ≥ α ₂ applies.

Preferably, the cap has a bottom wall with an inlet opening for the closure element.

These conical surfaces cooperate with a corresponding sealing surface, which is integrally formed on the screw cap. Preferably, the cap has on the bottom wall a projecting into the interior annular sealing lip with a conical sealing surface whose cone angle β = α ₂ . Since α ₁ ≥ α ₂ , an abutment of the closure element is achieved at the sealing surface early during the closing process and exerted in the course of further closing a large pressing pressure on the part of the sealing surface, which bears against the first conical surface.

Conversely, during the opening process, first the second conical surface will detach from the sealing surface and only at the end of the opening process will the second conical surface also be removed from the sealing surface. This allows a continuous opening, which is particularly advantageous at high internal pressures and prevents explosive discharge of the liquid in the outlet pipe.

Furthermore, manufacturing tolerances with respect to the actuating element and the closure element are effectively compensated by this arrangement of conical surfaces. By an additional widening of the sealing lip is a Maßreserve available, so that pivot pin and closure element can tolerate a certain amount of play, which reduces the cost.

According to a further embodiment, the inlet opening in the bottom wall has a return formed as a valve seat. This makes it possible to sink the valve disc in the closed position largely in the inlet opening, so that in the screw cap a largely closed flat bottom is created, which makes it possible to unscrew the container closure sealed with sealing film containers, without the sealing film protrusions in the interior of the Cap is damaged.

Preferably, the cap and thus also the annular sealing lip of a flexible or elastic plastic material. The closure element is preferably made of a stiff, non-deformable plastic material. The closure element may be dish-shaped and have stiffening ribs.

In principle, it is also possible to manufacture the cap from a rigid plastic material and to produce the closure element from a flexible elastic material.

According to a further embodiment of the sealing plate, this can be provided with a coating of an elastic polymer, preferably of a thermoplastic elastomer.

The material in the sealing area of the closure should have the so-called memory effect, d. H. have a resilience, so that due to pressure, time and temperature deformation after the opening process is possible quickly canceled.

Overall, the container closures represent a stable arrangement, so that an internal pressure of up to 6.5 bar at the container closure does not lead to any leaks.

Preferably, in the open position of the closure element, the free cross section between the valve disk and the sealing seat is smaller than the free cross section in the opening of the intermediate bottom. This embodiment has the advantage that foaming in the outlet channel is significantly reduced in the case of intumescent, in particular sugary liquids. In particular, at the beginning of the liquid removal is thereby ensured that the liquid content compared to the foam portion is significantly greater than is the case with conventional container closures.

An additional measure is to install a reflector plate in the outlet channel. For this purpose, the closure element preferably has a reflector plate in the outlet channel of the outlet tube, so that when flowing out through the opening of the intermediate bottom, a deflection of the liquid and thus a reassurance of a gas-liquid mixture occurs before the liquid enters the mouth of the user.

Preferably, the closure element has a stiffening rib extending through the opening of the intermediate bottom, on which the reflector plate is formed.

The reflector plate is preferably arranged perpendicular to the longitudinal axis of the container closure. For a complete deflection of the liquid flow takes place, the surface of the reflector plate ≥ the surface of the opening of the false floor. This means that the reflector plate preferably covers at least the opening of the intermediate bottom.

The inventive design of the container closure makes it possible to produce the components required for the closure with relatively large manufacturing tolerances, since in each case a seal is ensured due to the design of the sealing plate either as a conical sealing plate or as a sealing plate with elastic coating. Only then is it possible to manufacture the container closure inexpensively as a mass product.

The container closure is also characterized in that all components and surfaces that come into contact with the container contents during the liquid extraction, are smooth and have no hidden corners, so that easy cleaning is possible.

Because of these advantages, this container closure is particularly suitable for containers, in particular drinking bottles, with a carbonated liquid.

Exemplary embodiments of the invention are explained below with reference to the drawings.

In the figure 1a, a container closure 1 is shown in perspective. The container closure 1 has a screw cap 2, which has a corrugation 3 on the outer surface. At the bottom, the screw cap 2 has a tamper-evident ring 70.

Upwards, the screw cap 2 continues in a pouring part 20, which comprises an outlet tube 21 with an outlet channel 22 and with an outlet opening 24 (see FIG. 1b). In the pouring part 20, a pivot pin 30 is mounted perpendicular to the longitudinal axis 200 of the outlet channel 22, on which a lever 36 is integrally formed with a handle 37 (see Figure 1b). The spout 20 is covered by a protective cap 12 Originality ring 12 'covered, which is fastened on the screw cap 2 by means of the locking lugs 38. After removing the protective cap 12, the closure device 40, which has a closure element 40 and is arranged in the interior of the container closure, is opened by folding over the lever 36 and the container contents can be removed.

FIG. 2 shows a vertical section through the container closure 1 shown in FIG. The screw cap 2 has a peripheral wall 5, on the inside of which an internal thread 4 is arranged, with which the screw cap can be screwed onto a container opening, for example onto a drinking bottle. The peripheral wall 5 merges into a bottom wall 6, on whose underside a sealing ring 9 is provided, which cooperates with the opening edge of the container. Radially inwardly in the region of the inlet opening 23, a sealing lip 7 extending into the interior 10 of the cap 2 adjoins the sealing surface 8, which cooperates with the sealing plate 41 of the closure element 40, and forms a sealing seat 7a as in the following figures is explained. The closure element 40 has a bell-shaped form and extends through the inlet opening 23 of the outlet channel 22 upwards. The sealing plate 41 is provided with two conical sealing surfaces 42 and 43 and is articulated by means of an annular connecting element 47 on the pivot pin 30.

The pivot pin 30 is mounted in the spout part 20 in a bearing portion 25 a with its first central portion 31. This central section 31 merges into an eccentric section 33, on which the annular connecting element 47 engages.

The eccentric portion 33 merges into a second central portion 34, which is followed by a bearing plate 35. These Bearing disk 35 is rotatably mounted in the wall of the spout part 20 in bearing portion 25 b. Outwardly, the pivot pin 30 continues in a lever 36 which has a handle 37 at the free end.

In FIG. 2, the closure element 40 is shown shortly before the closed position. Accordingly, the eccentric portion 33 is turned upwards and the lever 36 also faces upward. For the operator it can be seen that this will soon be the closed position. When the closed position is reached, the annular connecting element 47 engages in the opening 29 in the intermediate bottom 28 and closes the opening 29th

By turning the lever 36, which can be done by a rotary movement to the right or left, the opening position of the closure element 40 is adjusted by pivoting the eccentric portion 33 down.

At the beginning of the opening process, the opening 29 is still closed. In the wall of the spout 20 pressure relief openings 27 are provided below the pivot pin 30, which expand conically outward. An overpressure first builds up through these pressure relief openings 27.

In the figure 3, the pivot pin 30 is shown enlarged. The first central section, which is mounted in the spout part 20, merges via a transition region 32 into the eccentric section 33, which extends into the second central section 34. This extension of the eccentric portion has the advantage that the annular connecting element of the closure element can not slip sideways, in particular in the closed position.

At the second central portion 34, the bearing plate 35 connects, which has a circumferential bead. The actuating lever 36 runs upwards wedge-shaped and has at the free end the trapezoidally shaped handle 37th

In the figure 4, the closure element 40 is shown in perspective. The closure element has a bell shape with a sealing plate 41, which has the two conical surfaces 42 and 43. At the top, a cup-shaped section 45 connects, which is reinforced by means of stiffening ribs 44. Above the cup-shaped portion 45, a vertical web 46 is arranged, which merges into the annular connecting element 47, which surrounds the eccentric portion 33 of the pivot pin 30. The opening 48 of the annular connecting element 47 has the shape of a slot. This configuration of the opening 48 has the advantage that the eccentric portion 33 can move in the horizontal direction, as can be seen in Figure 5a.

The annular connecting element 47 is reinforced with a reinforcing rib 49.

A schematic representation can be seen in FIG. 5a in order to explain the two conical surfaces 42 and 43 of the sealing plate 41 of the closure element 40 opposite the inlet opening 23 of the outlet channel 22. The detail X is also shown enlarged. The first conical surface 42 has a cone angle α1, which is greater than the cone angle α2 of the second conical surface 43, which adjoins the first conical surface 42 upwards. The sealing lip 7 has a sealing surface 8, which is also conical and has the angle β. In the illustration shown here, the angles α2 and β are chosen to be the same size.

In the figure 5b, the closed position is shown. It can be clearly seen that due to the larger cone angle α1, the first sealing surface 42 slightly presses the sealing lip made of elastic material with the sealing surface 8 to the outside. It is thus ensured early during the closing process a seal. Conversely, the opening 23 is fully released during the opening process only at the end. The configuration by means of two conical sealing surfaces 42, 43 different cone angle has the advantage that the seal can be done continuously, which is particularly advantageous for contents that are under high pressure.

FIG. 6 shows a further embodiment of the container closure. This embodiment differs from the preceding embodiment by a modified closure element 40. The closure element 40 has a sealing plate 41, which is provided with a coating 41 a of a soft plastic, in particular a thermoplastic elastomer. This coating 41 a is clamped in the edge region of the sealing plate 41 and extends over the entire underside. Radially outward, the coating 41 a is present, so that it can cooperate with the sealing surface 8 of the sealing lip 7 during the closing process. The sealing lip 7 is like the other components of the cap 2 made of a solid plastic and is therefore only partially compliant. Due to the elasticity of the coating 41 a is reversibly deformed when the sealing plate 41 is moved in the closed position. Any component tolerances are thus compensated by the coating 41 a, d. H. in existing manufacturing tolerances, a tight closure of the inlet opening 23 is achieved in each case.

Above the annular connecting element 47, a stiffening rib 49 extends upwards, which at its upper end a Reflector plate 400 carries. This reflector plate 400 extends perpendicular to the longitudinal axis 200 to both sides of the stiffening rib 49, wherein the surface of the reflector plate 400 is greater than the surface of the opening 29. When opening the container closure flows under pressure liquid from the opening 29 initially against the underside of the reflector plate 400 and is thereby deflected radially. This leads to a calming of the outflowing liquid. With carbonaceous liquid, the gas pressure initially discharges, entraining the liquid particle. This leads depending on the type of liquid also to a foaming. By the reflector plate 400, these liquid particles are deflected and significantly reduces the foaming.

Since the reflector plate 400 is preferably integrally connected to the reinforcing rib 49, as shown in FIG. 7, the latter is preferably designed to be able to be folded in such a way that it can be inserted from below through the opening 29 when the closure element 40 is inserted. After passing through the opening 29, the reflector plate 40 spans itself like a screen and assumes the position shown in FIG.

In FIG. 8, the closure element 40 can be seen in a perspective view. The sealing plate 41 has a substantially rectangular shape, which is adapted to the rectangular contour of the inlet opening 23. The coating 41 is fixed in the edge region of the sealing plate 41 and encloses the lower region of the sealing plate 41. On the sealing plate 41, a web 46 are formed vertically upwards, the stiffening ribs 44 has. Overall, a cross-shaped arrangement is created, which merges into the annular connecting element with the elongated opening 48. Upwards, the stiffening rib 49 connects, in the edge region Ribs 49a, 49b, so that a double-T-structure is created. At the upper end of the reflector plate 40 is formed.

FIG. 9 shows a further embodiment in which the bottom wall 6 in the region of the inlet opening 23 has a sealing seat 7a in the form of a recess. The sealing seat 7a is thus displaced into the inlet opening 23, so that in the closed position of the sealing plate 41 almost completely engages in the inlet opening, so that not or only slightly projects into the interior 10 at the bottom of the sealing plate. This makes it possible to screw the container closure onto a bottle neck 80 whose bottle opening 81 is closed at the end face with a sealing film 82. The sealing film is not or only slightly pushed inwards, but in any case not damaged, so that the sealing of the contents is retained.

FIGS. 10 and 11 show a second alternative in vertical section in the closed and open positions. The closure element 40 is formed identically with respect to the sealing plate 41. The sealing lip 7 also corresponds to the sealing lip of the previously described embodiment.

The closure element 40 has in the embodiment shown here a threaded pin 50 which is screwed into a threaded tube 65. This threaded tube 65 extends in the outlet tube 21 and is part of a rotary cap 60, which engages over the outlet tube 21 by means of a bottom wall 64 and a peripheral wall 62 with external corrugation 61. Furthermore, the rotary cap 60 has a mouthpiece 68. The peripheral wall 62 has on its inner surface a locking bead 63, which engages in a corresponding outer groove 26 of the outlet tube 21. The rotary cap is thereby rotatably mounted, but fixed in the axial direction of the outlet pipe 21. By turning the rotary cap 60 is about the thread 51, 67 of threaded tube 65 and threaded pin 50 causes a lifting movement of the sealing plate 41.

In order to prevent the sealing plate from rotating, a securing pin 52 can be formed on the sealing plate 41, which engages in a corresponding groove in the outlet tube 21.

In the figure 11, the open position is shown, in which the container contents can penetrate through the gap between the sealing plate 41 and sealing lip 7 in the outlet channel 22 of the outlet tube 21. From there, the liquid passes through the openings 66 into the interior of the threaded tube and can thus flow away.

Both alternatives of the container closure are particularly suitable for drinking bottles, the contents of which can be under high pressure, such. B. carbonated liquids.

The container closures can also be used for other liquid media.
