TAP AND CONTAINER OR BEER KEG HAVING A TAP

Abstract

A tap for the removal of liquid from a container, such as a 5L party beer keg, comprises a sleeve, a piston which can be drawn at least partially out of the sleeve, an outlet head which adjoins the piston and can be pivoted, typically in relation to the longitudinal axis of the piston, and has an outlet, and an actuator which is generally assigned to the outlet or arranged downstream of the same. The actuator serves to draw the piston out of the sleeve and thereby activate the tap, and to pivot the outlet head and thereby open a flow path extending at least partially through the sleeve and the piston to the outlet for tapping purposes. The actuator comprises a handle for drawing the piston out of the sleeve (for activation) and an actuating lever which is connected to the handle for pivoting the outlet head (for tapping).

DETAILED DESCRIPTION

[0033] FIGS. 1 and 2 show a container 1, namely a 5L party beer keg. The beer keg 1 is equipped with a special receiving or insertion region 2 for inserting and fastening a tap 3. Due to the asymmetrical design of the receiving region 2, the receiving region 2 and a correspondingly equipped flange of the tap 3 act in the sense of an anti-rotation lock.

[0034] FIGS. 2a, 2b, and 2c show the beer keg 1 with the receiving region 2, wherein a sleeve 4 of the tap 3 is inserted.

[0035] FIG. 3 shows the beer keg 1 with an overall inserted tap 3, whose components are shown in the following figures and are discussed in the corresponding figure description.

[0036] FIG. 4 shows an exemplary embodiment of a tap 3 with its components. This includes the sleeve 4, which is equipped with stabilizing structures 5. At its free end, the sleeve 4 has a flange 6, with which it comes to rest at the outer side of the beer keg 1 in the receiving region 2 thereof. Due to the asymmetrical design of both the flange 6 and the receiving region 2, an anti-rotation lock is created when the sleeve 4 is in the inserted state.

[0037] FIG. 4 also shows a joint 7, via which an outlet head 8 is pivotably articulated on the piston 9.

[0038] The piston 9 is provided with a marking 10 which indicates to the user that or whether the piston 9, and especially the outlet head 8, has been properly drawn out of the sleeve 4 so that the tap 3 is ready for operation.

[0039] The outlet head 8 is equipped with an actuator 11 which comprises a handle 12 for drawing the piston 9 together with the outlet head 8 out of the sleeve 4. The actuator 11 furthermore comprises an actuating lever 13, which serves to pivot the outlet head 8 forward or downward.

[0040] FIG. 4 also shows the components of the freshness seal 14, wherein the mechanical elements thereof are disengaged by breaking after the piston 9 has been drawn out. The connection of the mechanical elements 14 of the freshness seal is destroyed via a predetermined breaking point and can in this respect be seen by the user.

[0041] FIGS. 5a to 5c show, seen individually and enlarged, the outlet head 8 with the actuator 11, which comprises the forward bendable handle 12 and the actuating lever 13. In addition, it can be seen in FIGS. 5a to 5c that the outlet head 8 has a joint 15 with which the outlet head 8 is mechanically and also fluidically connected to the piston (not shown in FIGS. 5a to 5c).

[0042] FIGS. 5a to 5c also show the outlet 16, which can be pivoted relative to the longitudinal axis of the piston (not shown) by means of the actuating lever 13, whereby tapping is initiated, depending on the degree of pivoting.

[0043] Furthermore, the mechanical element 14 of the freshness seal assigned to the outlet head 8 can be seen in FIGS. 5a to 5c.

[0044] FIG. 6 shows a further exemplary embodiment of a tap 3 according to the disclosure, in which the actuator 11 has a special handle 12, namely in the form of shoulders 17 formed on both sides of the main body of the actuator 11, which shoulders can be engaged behind by two fingers in order to draw out the piston 9. An actuating lever 13 is arranged above the shoulders 17, in a similar way to the exemplary embodiment of FIGS. 4 and 5.

[0045] FIGS. 7a to 7c show the outlet head 8 together with the actuator 11, corresponding to the design of the tap 3 of FIG. 6. Special explanations are superfluous with reference made to the exemplary embodiment of FIGS. 4 and 5.

[0046] FIGS. 8a to 8c show an exemplary embodiment of a sleeve 4, as is used in the exemplary embodiments of the taps of FIGS. 4 and 5 and also 6 and 7.

[0047] The sleeve 4 has a sleeve body 18, which has reinforcing structures 19. These structures are formed on the surface of the sleeve body 18.

[0048] At the free end, the sleeve body 18 is provided with a flange 20, which is designed as an asymmetrical circular ring. It comes into contact with the outer surface of the beer keg 1 in the likewise asymmetrically formed receiving region 2 thereof and acts together with the receiving region 2 as an anti-rotation lock.

[0049] In the lower region of the flange 20, mechanical elements 14 formed as part of a freshness seal are provided and interact with a corresponding receptacle 21 in the outlet head 8. When the piston 9 together with the outlet head 8 is drawn out into the working position, the mechanical elements 14, 21 are recognizably separated from one another so that the user sees that the freshness seal created by the mechanical elements 14, 21 has been broken open. This is irreversible, which speaks for the quality of the freshness seal.

[0050] FIGS. 9a and 9b show pivot axes 22 formed at the head-side end of the piston 9 in the sense of pivoting bodies which are used for receiving or attaching corresponding recesses or passages in the outlet head 8. As a result, a pivotable mechanical and fluidic connection between the piston 9 and the outlet head 8 can be created.

[0051] In addition, the piston 9 is equipped with mechanical pivot limits 23 which effectively limit the pivoting movement of the outlet head 8.

[0052] Furthermore, the piston 9 has a latching feature which interacts with complementary elements on the inside of the sleeve 4 and limits the draw-out movement of the piston 9 relative to the sleeve 4. An internal anti-rotation lock prevents rotation of the piston 9 within the sleeve 4. A sealing surface of the piston 9 is indicated by reference sign 24 and seals the piston 9 against the sleeve 4. FIG. 9a furthermore shows a longitudinal groove at reference sign 9. In the assembled state, a stud which is formed on the sleeve 4 projects into this groove. When the piston 9 is drawn, it moves along the stud. If attempts were made to rotate the piston 9, the stud would block the rotation of the piston 9 within the sleeve 4.

[0053] On the surface, the piston 9 is also equipped with reinforcing structures 25.

[0054] It should be noted at this point that, according to various embodiments, all elements of the tap are preferably made of plastic and are preferably produced by injection molding.

[0055] With regard to further advantageous embodiments of the device according to the disclosure, reference is made to the general part of the description and to the appended claims in order to avoid repetitions.

[0056] Finally, it should be expressly pointed out that the exemplary embodiments of the tap according to the disclosure described above serve only to explain the claimed teaching but do not limit the teaching to the exemplary embodiments.
