Description

Dispenser

The invention relate to dispensers, comprising a beverage container and a dispensing device with a spigot.

Such dispensers are known in prior art. They serve the purpose of making it possible to pour a beverage from a keg or a can, whereby the keg or the can in the known way are provided with openings for inserting the dispensing device. With these dispensers, an internal pressure is build up by help of additional means in the form of external, auxiliary pressure means. It will thus be possible to fresh-pour beer as so called draught beer or other beverages

The invention in question concerns another type of dispensers, which do not have such auxiliary pressure means for admission of pressure for dispensing beverage, wherefore it is necessary to turn these dispensers in an overhead position to pour the beverage. However, it should be observed, that the inventive dispensers surprisingly may comprise any type of beverage containers.

Such beverage containers may comprise known containers, such as all kinds of bottles made of different plastics, or any kind of cans or kegs made of metal such as aluminium or steel. The beverage content could be anything, such as for example 0,33, 1 ,0, 1 ,5, 3,0 or 5,0 litres available in standardised containers. The beverage type itself could be any drinkable liquid, though the inventive dispenser is especially expedient for carbonised beverage.

During dispensing of the beverage from the container, air access is necessary to prevent build-up of vacuum in the container. For providing air access a ventilating conduit is arranged from the opening of the container to the bottom.

However, a quantity of beverage may be accumulated in the ventilating conduit, for example, when the ventilating conduit is lowered into the beverage, when the container and the dispensing device are brought together, when the container is shaked, when the container is exposed for temperature variations, or when the container is inverted. Consequently, the beverage will run out of the ventilating con- duit and will contaminate it's surroundings. The dispenser of the present invention comprises a beverage container and a dispensing device with a spigot, wherein a connecting part may be connected to the opening of the container, with which connecting part the dispensing device is arranged so relatively to the container, that a dispensing procedure with the dispensing device requires an overhead position of the container, and wherein a ventilating conduit has been provided at the connecting part extending therefrom to the bottom of the container, and means are arranged for avoiding dispensing of beverage through the ventilating conduit

The advantage of the inventive solution is, that unintended dispensing of beverage through the ventilating conduit is prevented in a secure manner Furthermore the inventive solution is a low-cost solution, which is especially simple and easy to manufacture

Surprisingly, build up of an internal pressure in the container may be provided without the use of any auxiliary pressure means as well

An advantageous embodiment provides, that the connecting part has been fitted with a seat for a connecting branch of the dispensing device, which seat is arranged excentπcally to the center line of the opening, thus allowing the dispensing device, for instance also for kegs and cans, to be formed in a conventional way, and only be insertable in the connecting part with the connecting branch and thus to provide more space for further provision of the ventilating conduit

The connecting part may be secured at the opening by frictional engagement, externally encompassing the opening or internally engaging into it

A solution being especially advantageous in respect of feasibility and producability provides, that the connecting part includes a plug, which is insertable into the opening and which plug with a circumferential outer mantle section sealingly rests at surfaces of the opening Due to its simplicity and favourable producability this solution offers big advantages, especially a screw cap could be avoided The ventilating conduit may extend through the connecting part, in order to provide access of air to the ventilating conduit in a simple manner

In a particularly expedient manner the ventilating conduit may extend from the connection part further through the dispensing device In this regard the ventilating conduit may extend from the connecting part, and further through an essentially, horizontal tubular housing at least to the spigot housing

The means for avoiding dispensing of beverage through the ventilating conduit may comprise a detachable plug to be inserted in the ventilating aperture or in the end of the spigot housing, whereby the ventilating conduit is sealed off for air access

In another expedient embodiment the means for avoiding dispensing of beverage through the ventilating conduit may comprise a floating device arranged at the end of the ventilating conduit at the bottom of the container, so the end of the ventilating conduit in ail positions of the container is kept securely above the surface of the beverage

In a particularly expedient manner the means for avoiding dispensing of beverage through the ventilating conduit may comprise valve means

The valve means may comprise a non-return valve, and the non-return valve may be arranged in the connection part

In a particularly expedient manner may the activating element of the spigot comprise closing surfaces, which seal off for air access to the ventilating conduit Hereby is obtained, that during operation of the activating element the air access for the ventilating conduit is sealed off at the same time, as the outlet tube for dispens- ing beverage is being sealed off Consequently, the activating element opens for air access at the same time, as the outlet tube for dispensing beverage is being opened as well

In an expedient manner the closing surfaces may coextend within the tubular hous- ing Finally, the closing surfaces may extend transversely to the tubular housing

The connecting part itself may be provided in the most variable sort and way. By way of example it might be possible to provide only for one aperture for the connecting branch and to make a tight end with an aperture edge at the connecting branch However, it is especially advantageous, when the seat has a seat sleeve for receiving the connecting part of the dispensing device to be inserted therein, thus in an especially advantageous way allowing to make a tight end in the area of the connecting branch, and besides by means of the seat portion also ensuring the dispensing device against tilting compared to the center line of the connecting part

In respect of the joining of the connecting part there will be a variety of possibilities Thus an advantageous solution provides, that the seat has been fitted concentrically to the connecting part itself, and thus concentrically to the center line of the opening as well

An especially favourable solution provides, that the ventilating aperture has been positioned next to the seat, thus to make access of air to the ventilating conduit re- alisable irrespective of the shape of the dispensing device

Any location of the ventilating aperture can be chosen So, an advantageous example of an embodiment provides, that the ventilating aperture has been provided in a bottom of the connecting part, and preferably in an external forepart of the connect- ing part

Furthermore, in order not only to ensure a tight closure of the plug in the opening, however, also an essentially tilt resisting support of the latter and the dispensing device, provision has been made to fit the plug with guiding elements, engaging into the opening and resting on the inner surface, resulting in stabilising the plug against tilting

Preferably thus the plug has been provided with guiding ribs, extending parallel to the centerlme of the opening, resting on the inner side of the opening. Especially suitable for formfittingly fixation is the external locking thread of the opening, which will primarily serve the purpose of fixing a screw lock to the opening This external locking screw thread may also be provided for the formfittingly fixation of the connecting part, whereby for instance the connecting part may engage with claws in the thread, in order to achieve an interlocking fixation A solution being especially favourable, however, provides that the connecting part is a nut being provided with external threads to be screwed onto the thread

Preferably bottles of plastics, being made of Polyolefin, have been used, especially Polyethylene and -propylene, and their derivatives or combinations, like for instance

PET or PEN

In respect of further construction of the dispensing device the most variable possibilities will be thinkable So, for instance, it might be thinkable to secure the over head position by ensuring that it is maintained hanging

Another preferred solution provides that the dispensing device includes a base, on which the container rests in over head position Such a base has the advantage on the one hand of being relatively compactly mountable and on the other hand, for instance for hanging up the container, provides the possibility of avoiding an expensive, constructive solution

The support could also be a rectangular box comprising the container

Further inventive characteristics and advantages will be object of the subsequent description and the graphical presentation of some examples of execution

An embodiment of an inventive dispenser, presented in Fig. 1 , comprises a traditional dispensing device 10 with a central, tubular housing 12, forming a connection conduit 14 between a connecting branch, provided at one first end of the housing 12, and a connection branch 16, and a spigot 18 placed at a second end of the housing 12, from where an outlet tube 20 extends radially to the longitudinal direction of the housing 12.

The spigot 18 comprises a spigot housing 22, in which a pouring plug 24 has been inserted, which comprises a stopping element 26 and an activating element 28, manually operable to turn the stopping element 26, being pivotally arranged in the spigot housing 22.

With the dispensing device 10 it is possible to pour a beverage, contained in a bottle 30 of plastics, being placed in over head position For this purpose the dispensing device 10 is secured to a bottleneck 44 by means of a connecting part 40 at the bottleneck 44, its shape being adjusted to the body of the bottle 43, preferably at an end area 46, which connects to an aperture 42 of the bottleneck 44 of the bottle 30 The connecting part 40 on the one hand makes a leak proof end between the con- necting branch 16 and the bottleneck 44, and on the other hand fixes the dispensing device 10 relatively to the bottle

By way of example the connecting part 40 has been formed as a plug 50, as presented in Fig 2-5, comprising a body of a plug 52, shaped as a cylindrical seat sleeve, holding at one end a sealing section 54 with a coaxial, circular cylindrical sealing area in relation to the center line of the plug Starting from this sealing section 54, extending still further parallel to the axis 56 are straightened ribs 60, having an external rib surface 62. being provided approximately in the same radial distance from the axis 56 as the circular cylindrical surface area of the sealing section 54, and having a sloping 64 at the end facing away from the sealing section 54, simplifying the insertion of the plug into the aperture 43 of the bottleneck 44

Between these ribs 60 recesses have been provided, serving the purpose of allowing elastic deforming of the ribs 60 in azimuthal direction to the axis 56

Furthermore the plug 50 comprise a flange 70 close to the sealing section 54, projecting in radial direction under the sealing section 54, and forming a flange area 72, being vertical to the axis 56, placeable at a front side 44 in the area of the aperture 42, thus forming a limit stop for pushing in the plug 50 into the end area 46 of the bottleneck 44

Further, the plug element 52 has an inner cylindrical area 76 serving the purpose of taking up the connecting branch, at an aperture 80 with a seat. By inserting the connecting branch 16 it is enclosed sealingly and leak proof A stopper bottom 78 is provided at the level of the flange 70 Between the sealing section 54 and an annular wall 82, which surrounds the seat aperture 80 circumferentially, and forms the connecting area of the cylindrical area 76, and a wall 82, which forming the circular cylindrical surface area 58 of the body of a plug 52, is provided a slit 86, allowing an elastic deformation of the wall 82, independent of the wail 84 The sealing end between the sealing section 54 and the end area 46 of the bottleneck 44, and the sealing end between the wall 82 in the area of the seat aperture 80 and the connecting branch 16, does thereby not influence one another mutually

Further in the plug base 78, next to the seat aperture 80, a ventilating aperture 90 is provided, from which a ventilating bore 92 leads through the plug base 78 and preferably into an extended recess 94 of the recess 66, parallel to the axis 56 A ventilating conduit is insertable into the ventilating bore 92, providing a liquid tight con- nection in the plug 50

Starting from the plug 50 the ventilating conduit 96 will now be extending into the inner 34 of the bottle 30, in fact preferably to the area of the bottom 36 of the bottle 30 The end 98 of the ventilating conduit 96 thereby being close to the bottom of the bottle

Preferably, the ventilating aperture 90 has been provided so that the housing part 2 will protect the ventilating aperture 90 against penetration of dirt, avoiding a directed lacking out of a beverage jet (Fig 1 ,7)

This position of the housing part 12 will be obtainable by ensuring, that the connecting branch 16 is inserted in one defined position of rotation in the seat of the connecting part 40

Via the sealing section 54 the plug will effect a liquid tight provision, connecting with the area of an inner wall 48 of the bottleneck 44, and furthermore the ribs 60 will serve the purpose of keeping the connecting branch 16 of the dispensing device 10 essentially tilting free and coaxial to a center axis 38 of the bottle 30 The plug 50 thus not only effects a sealing between the connecting branch 16 and the end area 46 of the bottleneck 44, however, at the same time a tilt resisting seat is provided for the connecting branch 16 at the end area 46 of the bottleneck 44.

In a second embodiment of the connecting part 40, as presented in Fig. 6, 7, 8, 9 and 10, the plug 50' is provided with a cylindrical area 76', excent cally displaced in relation to a center line 56 of the plug and serving as seat. The seat aperture 80 has been provided in the plug bottom 78 excenthcally to the axis 56. This will provide more room for the provision of the ventilating aperture in the area of the wall 78, comprising the cylindrical area 76 and the ribs 60.

Further the slit 86 between the wall 82 and the wall 84 does not anymore extend annularly, except for the ventilating bore 92, however, in form of two sickles 86', engaging laterally with the ventilating aperture 90 and the ventilating bore 92.

Besides, as shown in Fig. 8, the heights of the ribs 60' are different, no ribs have been provided at a rib free area 61 opposite the ventilating bore 92. At both sides the ribs 60' has a rib height increasing up to the ventilating bore 92.

Contrary to the first embodiment of the plug 52', the second embodiment of the in- ventive dispensing device with the plug 50' will be further advantageous, being modified compared to the first embodiment, which in respect of its elastic function, caused by the weakening in the area of the ventilating bore 92 providing a strong flexibility in this area.

Besides by this second embodiment, all those parts, being identical with those of the first embodiment, will be provided with the same marks of reference.

At a third embodiment of an inventive dispensing device, presented in Fig. 1 1 to 13, the connecting part 40 has been developed in form of a coupling ring 100, compris- ing in the area of a nut body 102 an inner thread 104, which engages with an outer locking thread 106 at the end area 46 of the bottleneck 44.

The bottom of the nut 106 extends into the body of the nut 102, overlapping the aperture 42 of the end area 46, and having an inner area of a sealing flange 108. A ring surface 110 which seals of with the bottleneck 44. From the bottom of the nut 106 rises a seat sleeve 116, the central axis 118 of which is arranged eccentrically to the central axis 38 of the bottleneck 44.

The seat sleeve 1 16 has an inner surface 120, which functions as a guiding surface for the connecting branch 16 and keeps this firmly against tilting.

The inner surface comprises further two radially beads 122 and 124, which rests at an inner sleeve surface of the connecting branch 16 with an increased sealing pres- sure, and thereby provides a liquid proof closure without a separate elastic sealing has to be arranged.

By the embodiments shown in Fig. 1 1 to 13, the seat sleeve 116 is arranged so that it extends at the same height as the body of the nut, seen in the direction of the central axis 38 of the bottleneck 44, and it is also possible, that the seat sleeve 1 16 is arranged so, that it rests at a side of the bottom 106 of the nut being opposite to the body of the nut 102, or rests in any position in between.

Further is the venting aperture 130 formed in the bottom 106 of the nut, from where the venting bore 132 extends through the bottom 106 of the nut, so that the venting tube 96 is sealingly insertable into the venting bore 132.

Due to the fact, that the seat sleeve 116 has been provided eccentrically to the center line 38 of the bottleneck 44, next to it sufficient space will be provided for the ventilating bore 132, allowing without problems to position the ventilating tube 96 next to the seat sleeve at the end area 46 of the bottleneck 44.

In the previously mentioned embodiments it was not being discussed in details, how the bottle 30 must be held in over head position. Here any possibilities will be thinkable within the scope of the present invention.

By a fourth embodiment, presented in Fig. 14, the difference in comparison to the first embodiment is, that the bottle 30' has a strongly expanded body 43' to which a shorter neck of the bottle 44' extends to the end area 46. Fig 15 shows the bottle 30 and the dispensing device 10 in a overhead position The ventilating conduit 96 is provided at the connecting part 40 extending therefrom to the bottom of the bottle The ventilating aperture 90 is provided in the connecting part 40 A piug 140 is detachably mounted in the ventilating aperture 90

As the detachable plug 140 is mounted in the ventilating conduit 96, the access of air to the ventilating conduit is sealed of Consequently, the beverage will not accumulate in the ventilating conduit as it is introduced into the bottle 30

When the beverage are to be dispensed from the bottle 30, the plug 140 is detached from the ventilating aperture 90 and the access of air to the ventilating conduit 96 is re-established Thereafter may the activating element 28 be operated Fig 16 shows the piug 140 detached from the ventilating aperture 90

Fig 17 shows another embodiment, by which the ventilating conduit 96, extends further from the connecting part 40 through the tubular housing 12 and to the end 141 of the spigot housing 22 A plug 140' is detachably mounted in the ventilating aperture 90 Fig 18 shows the plug 140' being easily removed from the ventilating aperture 90, as access to the plug is conveniently at the spigot housing

Fig 19 shows an embodiment of the ventilating conduit 96 which extends from the connecting part 40 further through the tubular housing 12 to within a separate central duct 148 of the activating element 28 A plug 140" is detachably mounted at the end 141 of the activating element 28 thereby closing of that duct 148 Fig 20 shows the plug 140" detached from the end 141 of the spigot housing 22 By this embodiment, access to the ventilating aperture 90 is provided through the duct 148 of the activating element 28

Fig 21 shows a particularly expedient embodiment, where the ventilating conduit 96 also extends further through the tubular housing 12 and terminates with its aperture

90 at an inner compartment 149 of the activating element 28 The compartment 149 is closed of by a transverse element 142. An aperture 143 for providing air access to the compartment 149 is arranged in the wall of the tubular housing 12 and an other aperture 150 is arranged in an inner, coaxially extending part of the activating element 28 having closing surfaces within the tubular housing 12, which are coex- tending within the tubular housing 12.

At the position of the activating element 28 shown in Fig.21 , the apertures 143, 150 are in a position where they are placed over each other, and where access of air is provided through the apertures to the compartment 149 and further through the ventilating conduit 96 to the bottom of the bottle 30. The result of this is, that the beverage will be dispensed from the bottle 30 through the tubular housing 12 to outlet tube 20, and the air will replace the dispensed beverage in the bottle.

At the closed position of the activating element 28 shown in Fig. 22, the apertures 143, 150 are displaced 180° in relation to each other. The access of air to the compartment 149 is thereby closed off. At the same time there is closed for dispensing beverage.

Hereby is obtained, that during operation of the activating element 28 the air access for the ventilating conduit 96 is sealed off at the same time, as the outlet tube 22 for dispensing beverage is being sealed off. Consequently, the activating element 28 opens for air access at the same time, as the outlet tube 22 for dispensing beverage is being opened as well.

In another embodiment the closing surfaces are extending transversely to the tubular housing 12.

Fig. 23 shows an embodiment in which the ventilating conduit 96 is provided at the connecting part 40. A non-return valve 144 is arranged in the ventilating aperture 90.

When the outlet tube 20 is open and the beverage is dispensed from the bottle 30, a ball 145 is lifted, as shown in Fig. 24, due to the vacuum in the bottle 30. As the ball

145 is lifted, air access to the ventilating conduit 96 is established and air is lead into the bottom of the bottle 30. A stop element 146 prevents the ball 145 to continue further up in the ventilating conduit 96 and thereby permanently closing for air access. Fig. 25 shows the position of the ball 145 when beverage is not dispensed from the bottle 30. In this position of the ball 145, air is prevented for being lead into the bottle 30.

Surprisingly, it was found that, by the above explained embodiments, build up of an internal pressure in the container may be provided without the use of any auxiliary pressure means as well. The means for avoiding dispensing of beverage through the ventilating conduit 96 will simply close off to the inner of the bottle, so that by shaking or heating an internal pressure may be build-up in the bottle. At the above embodiment, i.e. Fig. 23-25 the internal pressure is secured by the non-return valve

144 automatically closing off for any possible entry of air. Thereby the beverage will be fully pressurised during dispensing.

Fig. 26 shows the bottle 30 and dispensing device 10 in a overhead position. The ventilating conduit 96 is provided at the connecting part 40. A floating device 147 is arranged at the end 98 of the ventilating conduit 96. The floating device 147 have the necessary buoyancy, so the end 98 of the ventilating conduit 96 in all positions of the bottle 30 is kept securely above the surface of the beverage. Fig. 27 shows the bottle 30 in a position, which is not overhead, and the position of the floating device 147 in this position of the bottle 30.

The floating device 147 is by this embodiment shown as a plastic buoy with air provided as buoyancy means. Such buoyancy means could comprise several other types of materials, such as foam or other lightweight materials.

The ventilating conduit 96 is by this embodiment made of a flexible material.

The dispenser device 10 are in the shown embodiments essentially horizontal, but can have all kinds of directions in relation to the vertical axis of the bottle, such as vertical, horizontal or inclined.

It should be noted, that the ventilating conduit could be made of a stiff material, or could be fastened to the inside of the container, i.e. close to the bottom of the container for securing, that the end of the conduit is always free of the beverage in the overhead position of the container.
