Description

The invention relates to a device for receiving and dispensing beverages. Both alcoholic and non-alcoholic beverages are contemplated, with the inclusion and dispensing of beer or other carbonated beverages being preferred.

Generic devices are known from the prior art, each comprising a container for the beverage to be dispensed and a stand connected to the container dispensing device. The container and the dispensing device can be designed and sold separately. The connection of the container and the dispensing device is often complicated because of the necessary tightness. In generic devices in which the container and the dispensing device represent an already interconnected unit, often the storage of the liquid is not optimal.

Out DE 20 2005 016 212 U1 and EP 2 022 751 A2 Party kegs have become known which have a football-shaped hollow body for receiving a drink.

The invention has for its object to provide an improved device for receiving and dispensing drinks. Furthermore, a device is to be provided in which the quality of the beverage is not impaired over an extremely long period of time and a production method for such a device.

This object is achieved by the features specified in the claim 1. Embodiments of the invention are indicated in the dependent claims.

Embodiments of the invention are particularly advantageous because the use of a stretch blow molded container is made possible. The stretch blow molded container has a lower opening through which the outflow channel is formed. This lower opening is used to blow in gas for stretch blow molding a preform from which the container is made. After stretch blow molding, a vent opening is formed at the top of the container by, for example, being cut or punched out. In this vent opening, the coupling body is mounted, by screwing two coupling body elements. Through the coupling body, the container can be coupled to a filling device, for example, a conventional filling system to fill the container with a drink. When the coupling body elements are plastic injection molded parts, the container up close liquid-tight and gas-tight to a pressure of, for example, 10 bar when the closure insert is screwed into the internal thread of the second coupling body member.

It is particularly advantageous that the coupling body elements and preferably also the closure insert can be manufactured as plastic injection molded parts with correspondingly small tolerances so as to compensate for the relatively large tolerances, in particular with regard to the wall thickness of the wall of the stretch blow molded container. By screwing the first and second coupling body elements, the wall located below the bearing surface of the second coupling body element in an edge region of the ventilation opening is pressed between the coupling body elements, so that the wall deforms and thereby the Ventilation opening is liquid-tight and gas-tight through the coupling body elements is completed towards the top.

According to one embodiment of the invention, the first and second coupling body elements are locked screwed together, so as to ensure a particularly reliable seal.

According to one embodiment of the invention, the second coupling body element has recesses on its upper side. A tool may be inserted into the recesses to apply torque to the second clutch body member so that it is bolted to the first clutch body member.

According to one embodiment of the invention, a filling opening is formed by the internal thread of the second coupling body element, through which the container can be filled with the beverage, in particular by a filling machine, as it is also used for filling party kegs. After filling, the closure insert is screwed into the internal thread of the second coupling body element to seal the container gas-tight and liquid-tight for transport and storage until use.

According to one embodiment of the invention, the closure insert is a plastic injection-molded part with a ferromagnetic insert. The ferromagnetic insert simplifies the automatic screwing of the closure insert into the internal thread of the second coupling body part.

For example, embodiments of the device according to the invention and separately with closure inserts to a bottler, such as a brewery. A larger amount of the closure inserts is fed to a bottling plant separate from the devices. After filling one of the devices according to the invention, one of the closure inserts is automatically picked up by the filling system with the aid of a magnetic gripper and screwed into the internal thread of the device which has just been filled. Here, the ferromagnetic inserter can serve as a positioning aid for the gripper.

According to one embodiment of the invention, the closure insert has a circular arc-shaped recess into which the edge of a coin can be inserted. When a user applies torque to the coin inserted in the recess, he or she can unscrew the closure insert from the internal thread a distance, so that a pressure equalization for removal of the beverage can take place from the container.

According to embodiments of the invention, the device comprises a closure element for interrupting a flow connection between the container and the dispensing tap. By an actuating element can be acted on the closure element to open the closure, so that a flow connection between the container and the dispensing tap is released, so that the removal of the beverage is made possible from the container.

According to one embodiment of the invention, the liquid contained in the container originally, d. H. after filling the device with the beverage by the bottler, in its delivery condition to the end user, do not reach the dispensing tap, but only up to the closure element.

According to one embodiment of the invention, the closure element includes one or more seals which release the flow connection after actuation of the actuating element. The seals can be formed by O-rings

According to one embodiment of the invention, the device comprises an impact projection which can interact with the closure element and thereby release or open the flow connection between the container and the tap.

In a further aspect, the invention relates to a method for producing a device according to the invention. According to one embodiment of the invention, the method comprises the steps of: providing a preform of plastic, stretch blow molding the preform to make the container, making the vent opening, providing the first and second coupling body members and the closure insert, wherein at least the first and second coupling body elements are plastic injection molded parts, mounting the first and second coupling body elements in the ventilation opening to form the coupling body.

In the embodiment considered here, the coupling body element is located 60 completely in the liquid storage room 4 whereas the clutch body element 61 has a bearing surface which on the outside of the wall 3 rests. The clutch body elements 60 and 61 are screwed together so that the wall 3 in the area of the bearing surface between the coupling body elements 60 and 61 is pressed. The wall 3 can deform in this area, so that the vent opening is liquid-tight and gas-tight upwards after the closure insert 14 into the internal thread of the coupling body element 61 has been screwed.

Hereinafter, the assembly and the function of the device according to the 1 to 3 described. It is from 2 assumed the originally separate state of the container 1 and the dispensing facility 2 shows.

In the liquid storage room 4 is the liquid to be dispensed. Through the closure element 16 the liquid is trapped there tightly. Also by the ventilation device 12 The liquid can not escape from the liquid storage space 4 get outside.

The dispensing facility 2 is over her stand edge 17 to ensure a flat surface. Then the container 1 to the dispensing facility 2 to join. This is the coupling piece 8th along the central longitudinal axis M from above into the receptacle 18 introduce. The external thread 9 of the coupling piece 8th is in the internal thread in the receptacle 18 screwed in. Other connections between the container 1 and the dispensing facility 2 can also be provided. For example, a bayonet connection can also be used.

After the influence projection 21 from below into the recording 18 sticks out when inserting the coupling piece 8th in the recording 18 from the impact tip 22 the closure element 16 on the container 1 penetrated from below, so that the liquid then via the outflow channel 15 from the liquid storage room 4 can escape. The liquid passes or flows through the destroyed closure element 16 , Through the connection opening 23 can remove the liquid from the container 1 from the top into the extraction pipe 24 up to the tap 27 reach.

In the inserted state of the coupling piece 8th in the recording 18 who in 3 Shown is the jacking bridge 10 of the coupling piece 8th at the top of the bearing body 26 issue. The jacking bridge 10 thus limits the maximum insertion path of the coupling piece 8th in the recording 18 ,

As already mentioned, the tap is located 27 in 2 in his closed position. In the closed position, the liquid can not through the discharge opening 34 the tap cock 27 escape. The sealing coat 40 is namely on the spring-loaded locking body 29 down against a sealing surface 45 of the housing body 28 pressed tightly. The screw-pressure spring 39 holds the barrier body 29 in this position.

To tap the liquid is by manually pivoting the handle 42 around the joint pin and thus also the toggle body 43 the blocking body 29 to move axially upwards. This will make the sealing jacket 40 from the sealing surface 45 lifted. In the opening position of the tap cock 27 as mentioned in 3 is shown, is the discharge opening 34 for the liquid to the outlet open or released. If on the handle 42 no external force is applied, presses the screw-pressure spring 39 the blocking body 29 back to his closing position.

When connecting the container 1 to the dispensing facility 2 There is an automatic opening of the liquid storage space 4 through the influence projection 21 , A separate, manual removal or destruction of the closure element 16 not necessary. In the removal pipe 24 is liquid only when the container 1 to the dispensing facility 2 has been connected. Before that, the liquid is in the liquid storage room 4 locked in.

The following is with reference to the 4 and 5 a second preferred embodiment of the invention described. identical Parts are given the same reference numerals as in the first embodiment, the description of which is hereby incorporated by reference. Structurally identical parts are given the same reference numerals as in the first embodiment, to the description of which reference is hereby made. Structurally different, but functionally similar parts receive the same reference numerals with a subordinate "a".

The device according to this embodiment differs from the previous embodiment by the design of the dispensing device 2a , In particular, the difference lies in the other embodiment of the bearing body 26a , Under the recording 18 is here in the camp body 26a a bushy leadership 47 for storage of the impact projection 21a serves. The leadership 47 is open up and down. It is cylindrical. The central longitudinal axis M passes through its center. The leadership 47 is by an annular wall in cross-section 48 bounded by the ground surface 19a goes down. The removal pipe 24 opens laterally into an upper area of the wall 48 ,

The connection opening 23 becomes essentially sideways through the wall 48 limited. She is back in the ground area 19a educated. An upper inflow section of the conduit wall 25 is also part of the soil surface 19a ,

The influence advantage 21a again has an upper impact tip 22 on. Furthermore, the influence advantage 21a a lower hollow cylindrical guide section 49 , who for the leadership of the influence-projection 21 in the lead 47 provides. In the guide section 49 is a seal ring in a ring groove 50 housed sealingly on the wall 48 is applied. The influence advantage 21a jumps from an upper ground surface 51 forth at the top of the guide section 49 is provided and the guide section 49 lid-like closes. Furthermore, the influence advantage 21a Locking projections 52 in the guide section 49 ,

Hereinafter, the mounting or operation of the device according to the 4 and 5 after the connection of the container 1 with the Zapf device 2 described.

In 4 is the influence projection 21a in his lower resting position. Its impact tip 22 is located below the closure element 16 which is still intact and thus the liquid storage space 4 of the container 1 tightly closes. The influence advantage 21a is in this position by the locking projections 52 fixed in the corresponding, in the wall 48 envisaged latching recordings latching engage.

The closure element 16 is by the manual operation of the impact projection 21a to penetrate or pierce. To transfer the impact projection 21a from the lower resting position according to 4 in the in 5 shown upper position of action is from below a manual, in the direction of the recording 18 directed actuation force on the guide section 49 apply, so that the locking projections 52 be pressed out of the rest-exceptions and the influence-projection 21a up along the central longitudinal axis M in the direction of the closure element 16 is moved. During the displacement, the influence projection penetrates 21a with its impact tip 22 the closure element 16 so that in the container 1 contained liquid over the coupling piece 8th can flow out. This is the result of the influence projection 21a destroyed shutter element 16 happens or flows through.

In the action position of the impact projection 21a Aligns the ground area 51 with the lower part of the pipe wall 25 so that's out of the clutch piece 8th leaking fluid through the connection port 23 in the withdrawal line 24 flows. The seal ring 50 prevents the liquid from passing over the guide 47 the camp body 26a can leave. To discharge the liquid from the withdrawal pipe 24 is the tap tap 27 , as described above, to operate again. Reference is made to this.

The following is with reference to the 6 and 7 A third embodiment of the invention is described. Identical parts are given the same reference numerals as in the second embodiment, the description of which is hereby incorporated by reference. Structurally different, but functionally similar parts receive the same reference numerals with a subordinate "b".

In essence, the device corresponds to the 6 and 7 in the 4 and 5 illustrated device. The dispensing facilities 2a are identical. In contrast to the device according to the 4 and 5 is the container 1b not a closure element 16 on the coupling piece 8th locked.

The container 1b and the dispensing facility 2a form a unity here. So the device is also distributed. Here is the connection opening 23 the dispensing facility 2a through the closure element 16 locked. The closure element 16 is thus at the dispensing facility 2a attached. It's on the wall 48 in the area of the ground surface 19a appropriate.

In terms of installation and function is on the embodiment according to the 4 and 5 directed. Again, the liquid from the container 1 only then in the removal line 24 arrive when on the shutter element 16 has been acted upon. Again, the shutter element 16 again permeated.

The 8th shows an exploded view of another embodiment of a device according to the invention. In the embodiment according to 8th is the closure element 16 not provided. The container 1 is therefore after its installation on the Zapf device 2 with this in flow connection, being a gasket 62 , which is at the bottom of the coupling piece 8th is arranged, ensures the tightness.

The seal 62 can be designed as a sealing ring, ie as so-called. O-ring, as in the 8th shown. As a closure element, which controls the flow connection between the container and the tap 27 originally interrupts, serves in this embodiment, a closure part 66 , At the closure part 66 are in the vertical direction one above the other two O-rings 64 and 65 arranged. The closure part 66 is connected to a connector 63 attached to the dispensing facility. The delivery part contains the closure part 66 in its lower position, in which the O-ring 64 the removal line 24 closes.

By manual operation of the closure part 66 this can be pushed upwards so that the O-ring 64 the discharge line releases, and so that the beverage can flow into the discharge line. The O-ring 65 then serves the tap facility 2 to seal downwards (cf. 13 and 14 ). The lower section 67 of the closure part 66 serves as an actuator, for example, with the palm from below the section 67 and thus the closure part is pushed upwards, thus the closure element, ie the O-ring 64 to move up so that this is the removal pipe 24 releases.

Through the connecting part 63 and the closure part 66 a so-called tamper-evident closure can be formed, ie the push-up of the closure part 66 to release the withdrawal line 24 is not reversible. For example, the closure part 66 in its upper position, in which the removal line is released, lock irreversibly. Alternatively or additionally, during the pushing-up of the closure part 66 break a predetermined breaking point. This makes it obvious to the end user whether the device is still in its delivery condition or whether it has already been put into use.

The coupling body element 60 has an annular bearing surface 70 whose diameter is larger than the diameter of the ventilation opening 11 so that the bearing surface 70 after positioning the coupling body element 60 under the ventilation opening 11 on the inside of the wall 3 is applied.

The 11 shows a perspective view of an embodiment of the coupling body element 61 , The coupling body element 61 has an external thread 71 for screwing into the internal thread 68 of the coupling body element 60 , Towards the top is the clutch body element 61 through a hexagonal ring 72 completed. On the top of the ring 72 there are recesses 73 over which a torque z. B. with a torque wrench 81 (see. 16 and 17 ) on the clutch body element 61 can be exercised to this with the clutch body element 60 to screw.

On the bottom of the ring 72 is a support surface 74 formed after the insertion of the external thread 71 into the ventilation opening 11 rests on the outside of the wall.

The coupling body element 61 also has an internal thread 75 , which is used to hold the lock insert 14 serves. The internal thread 75 forms a filling opening for filling the container.

The 12 shows an embodiment of the closure insert 14 , The shutter insert 14 has an external thread 76 for screwing into the internal thread 75 of the coupling body element 61 , When the shutter insert 14 in the clutch body element 61 is screwed, so this is up liquid and gas tight.

The shutter insert 14 has a circular arc-shaped recess 77 along a diameter of the closure insert 14 runs. The radius of the circular arc-shaped recess is chosen so that it corresponds approximately to a conventional coin, such as a 50-cent, 1-euro or 2-euro coin, which can be inserted with its edge in the recess, so a user on the coin torque on the lock insert 14 can exercise this in the internal thread 75 loszudrehen. This is to remove the drink from the container 1 required to provide pressure equalization.

According to one embodiment of the invention, the closure insert has 14 one or more depositors 78 made of ferromagnetic material. The depositors 78 are used to make the closure insert 14 placed in a plastic injection mold before the plasticized plastic is injected into the plastic injection molding tool. The depositors 78 simplify the mechanical assembly of the lock insert 14 on the coupling body element 61 after filling the container 1 , For example, a gripper of a filling plant can use a single closure insert 14 because of the depositors 78 easily pick up and position with the aid of a magnetic gripper.

The 13 shows a detailed view of the dispensing device 2 according to the embodiments of 8th and 9 , where the closure part 66 is in its original delivery condition, in which no drink from the filled container 1 has been removed. In this position, the O-ring closes 64 an outflow opening 79 that in the bottom surface 19 the recording 18 is trained. So it can not drink from the liquid storage room 4 through the discharge opening 79 via the withdrawal line 24 from the tap 27 be removed.

The 14 shows the device according to 13 after the closure part 66 has been operated by, for example, with the palm of your hand from below the section 67 has been pushed up. This will be the seal 64 moved a little way up, so that the seal 64 the outflow opening 79 releases. This allows the beverage from the liquid storage room 4 in the withdrawal line 24 flow.

The 15 to 17 show various steps of a method according to the invention for the manufacture and assembly of the device.

First, the various elements of the device are manufactured. For example, the container 1 made from a preform by means of a stretch blow molding process, as explained above. In contrast, in particular, the clutch body elements 60 and 61 produced by plastic injection molding. For mounting the coupling body elements 60 . 61 on the container 1 the procedure is as follows:

The support dome 80 Has an upper opening, which holds the underside of the coupling body element 60 with the projections 69 is trained. The support dome 80 with the applied coupling body element 60 is then through the coupling piece 8th introduced from below into the container until the coupling body element with its bearing surface 70 from below in an edge area of the ventilation opening 11 on the wall 3 is applied. From above then becomes the clutch body element 61 through the ventilation opening 11 through with its external thread 71 on the internal thread 68 of the coupling body element 60 placed and with the help of a torque wrench 81 tightened, while the support dome 80 is fixed (cf. 16 and 17 ).

Through this countered screw connection of the coupling body elements 60 and 61 becomes the wall 3 in an edge area of the ventilation opening 11 between the bearing surfaces 70 and 74 the clutch body elements 60 . 61 compressed and deformed so that a liquid-tight and gas-tight arrangement results. It is particularly advantageous that tolerances of the wall thickness of the wall 3 can be compensated by the compression.

After mounting the coupling body 13 becomes the support dome 80 from the container 1 pulled out and the container 1 will then be on the tap facility 2 assembled. Thereafter, the device may be passed from above through from the coupling body member 61 formed inlet opening to be filled. After filling, the lock insert becomes 14 screwed into the internal thread to close the inlet opening liquid-tight and gas-tight for transport and storage.
