thus trained, in particular made of PET containers or bubbles are often with a sack or introduced therein provided the same bag for receiving the drinks. This unfolds when filling and prevents Air enters the drink or carbon dioxide escapes.

The containers or bubbles are preferably used in beverage dispensing facilities for CO ₂ -gas operated serving of tempered to drink temperature drinks such as beer, soft drinks and wine. When a dispensing lever is actuated, the beverage is expelled to the beverage outlet via a riser tube projecting from above into the interior of the bladder or inner bag.

Such a beverage dispensing device is, for example, by the EP 1 293 476 B1 known. The beverage can be removed or the bladder can be filled via a safety fitting arranged on top of the container or the bladder, which has a beverage valve and a gas valve, can be placed on a dispensing head or an attachable connection piece.

By the DE 10 2005 025 561 A1 is a trained for the removal of liquid closure for a beverage container has become known, which has a closure body with a cylindrical inner part in which a valve actuator is mounted. The closure body has a cylindrical outer sleeve with an internal thread with which the outer sleeve can be screwed onto an external thread of the container neck.

Of Further, it is known in the art that the tap head receiving safety fitting when installed in the container top is pressed with the container wall, whereby a not again releasable connection arises. These so-called disposable threads are pressed together with the pressed after the beverage withdrawal Safety fitting disposed of.

Of the Invention is based on the object for a generic Beverage containers a safe and replaceable To provide connectivity with the safety fitting.

These Object is achieved by a connecting means the bubble with a locking groove of the fitting from the outside connecting, according to an advantageous embodiment of the invention immediately formed on the connection means and thus an integrated, non-loseable component of the bubble performing adapter ring solved. In these the fitting only needs to be inserted to become a locking projection of the adapter ring in the locking groove engages the fitting. Such an adapter ring allows it, a conventional one-way fitting for a Use PET bubble.

A another embodiment of the invention provides a one-piece, with the locking groove of the fitting and the collar-like connection means the bubble lockable adapter ring in front. The separate, made of a plastic material manufactured adapter ring is before connecting the fitting with the Bubble pushed from below onto the fitting. After the fitting under Interposition of a radial seal on one within the Collar-like connection means of the bubble circumferential, smooth-surfaced Projection was put on, the adapter ring is on the fitting in the vertical direction shifted so far down, on the one hand its upper connection end with the circumferential groove of the fitting and On the other hand, its lower terminal end with the collar-like or annular protruding connecting means of the bubble locked.

To the Locking of the adapter ring with the fitting and the bladder is proposed according to the invention, that the upper and lower terminal end of the adapter ring with locking projections is formed, of which the upper locking projection in the locking groove engages the fitting and the lower locking projection the collar-like Connecting means engages. Both the upper and the lower Detent projection is in one piece and circumferentially on the inner circumference formed of the upper and the lower terminal end of the adapter ring. The upper diameter matched to the outer diameter of the fitting Connecting end points opposite to the outer diameter of the collar-like connection means adapted lower connection end a smaller diameter, so in the transition the adapter between the upper and the lower terminal end one tapering oblique surface results. This inclined surface or step of the adapter ring is biased after latching the fitting with the bladder flush on a complementary nose-shaped trained outer contour of the collar-like connection means on, whereby a stabilization of the adapter ring is achieved.

A preferred embodiment of the inven It provides that the connection ends are connected radially resiliently to the middle part of the adapter ring. As a result, the terminal ends on the inner, upper and lower locking projections during the connection process on the one hand on the fitting and on the other hand on the oblique outer contour of the collar-like connection means are expanded to the outside. As soon as the upper locking projection is in covering position with the circumferential groove in the fitting and the lower locking projection has passed the collar-like connection means, the connecting ends spring back or snap back into their starting position, wherein the upper locking projection securely and firmly engages in the groove of the fitting and the lower latching projection engages the collar-like connection means positively.

A Another preferred embodiment of the invention provides that the upper locking projection with a downwardly tapered Insertion bevel is formed. This centered the fitting and facilitates the sliding of the adapter ring. moreover slides the locking projection thus formed with a small contact surface over the fitting, as well as the immersion of the upper locking projection in the groove of Fittings is favored.

In contrast, is the lower locking projection according to the invention with an upwardly tapered run-up slope educated. This allows when slipping the lower terminal end of the adapter ring on the collar-shaped Connecting means of the bubble a centered, easy slide down on the nose-shaped outer contour of the collar. Furthermore, by the run-up slope, the radial spread of the lower terminal end when passing the collar-shaped Supported connection means.

Further Features and details of the invention will become apparent from the claims and the following description of illustrated in the figures Embodiments of the invention. Show it:

1 in a longitudinally sectioned partial view of a connected with a collar-like connection means of a container bladder by an inserted from the outside adapter ring or latched fitting; and

2 a longitudinally sectioned section as before, wherein here the adapter ring is formed as an integral part of the container bubble immediately at the collar-like connection means.

In 1 is a bladder made of thermoplastic material, especially PET 1 shown for receiving or for pressure-gas-driven dispensing of beverage liquids such as beer, soft drinks and wine.

At the top is the bubble 1 with a bladder neck 2 formed, which a safety fitting 3 the one in the bladder 1 protruding fitting or riser 4 has, over which the liquid rises. Furthermore, the safety fitting 3 with closable openings 5 . 6 on the one hand a compressed gas and on the other hand provided the liquid. To the openings 5 . 6 can be used to fill with a beverage liquid in, for example, a brewery a connection piece or for tapping by the consumer a tap head.

The safety fitting 3 has an annular outer housing 7 that with a circumferential locking groove 8th is provided. The outer housing 7 goes down in a double-walled, stationary support member 9 over, between its inner ring wall 10a and outer ring wall 10b Flow channels are formed, wherein the inner ring wall 10a at the same time a guide for the embodiment adjustable in the longitudinal direction of the fitting tube 4 ready.

The outer ring wall 10b has a circumferentially projecting web section 11 on, on the one hand, the annular outer housing 7 on the other hand, with the interposition of a seal 12 on one inside the bladder neck 2 trained ring surface 13 supported.

At its outer periphery is the bladder neck 2 with a collar-like connection 14 provided, which serves as a counter-latching for a connecting means. The connecting means is a one-piece adapter ring 15 formed at its upper terminal end 15a and its lower terminal end 15b inside with locking projections 16 . 17 is provided, of which the upper locking projection 16 in the locking groove 8th engages the fitting and the lower locking projection 17 the collar-like connection means 14 engages below.

For non-positive and positive connection of the fitting 3 with the bubble 1 is made of a resilient material adapter ring 15 favored by an insertion bevel 20 of the upper connection end 15a from below over the annular outer housing 7 of the fitting 3 slipped, wherein the upper, circumferential locking projection 16 expanded radially outward and thus biased. Subsequently, the fitting 3 with the supporting part 9 in the bladder neck 2 inserted and the adapter ring 15 moved down. Along with it slides the lower locking projection 17 over the nose-shaped outer contour 18 the collar-like connection means 14 , whereby it is also radially expanded and biased. One at the locking projection 17 having formed te, upwardly tapered run-up slope 19 facilitates the assembly and the radial spread.

As soon as the upper locking projection 16 in covering position with the locking groove 8th located and the locking projection 17 the collar-shaped connection means 14 has completely happened, locked the upper locking projection 16 supported by the insertion bevel 20 with the locking groove 8th , and the lower locking projection 17 engages under the collar-like connection means 14 form-fitting.

The 2 shows a variant in which the adapter ring 115 immediately to the bladder neck 2 or its end-side, upper connection means 14 is formed. The resilient adapter ring 115 owns, as a catch with the bladder neck 2 or connection means 14 not applicable, here only one with an insertion bevel 20 provided, circumferential locking projection 116 when pushing the fitting 3 in its locking groove 8th engages and the bubble 1 safe with the fitting 3 combines.
