Definitions
- the invention relates to improvements in containers such as a keg for housing pressurised fluids like beer.
- the invention relates to improvements in fittings for such kegs which fittings house a valve which facilitates ingress and egress of pressurised fluid into and out of the keg.
- fitting for pressurised kegs comprising an upper flange for attachment of a connector to a feed or outlet pipe.
- the fitting further comprises a valve consisting of a movable seal urged by a coiled spring against a valve seat provided on the under side of the upper flange.
- the flange is disposed away from the top wall of a keg to enable attachment of the connector.
- known kegs and keg fittings require a multiple stage filling process in order to reduce frothing and to attempt to facilitate complete filling of the keg to required volumes of fluid such as beer.
- a multiple stage filling process wherein the fitting is below the rest of the keg, it is known to begin filling the keg at a first (low) flow rate or pressure for a short period of time say 5 seconds, followed by a second stage of filling at a slightly higher speed or pressure for say a further 5 to 10 seconds, followed finally by filling of the rest of the keg at a third higher speed or pressure for say a further 35 seconds.
- This multiple stage filling process is done to achieve relatively quick filling without excessive frothing of a liquid such as beer.
- One objective of the invention is to provide a fitting for a container such as a pressurised keg which enables a single stage filling process and/or enables a reduction in the filling time of a keg.
- Another object of the invention is to provide a relatively simple to manufacture and cost effective fitting for kegs.
- a further object of the invention is to provide a keg which is easier to manufacture, and or has a valve fitting that is less likely to cause problematical frothing during filling.
- a container such as a keg for housing pressurised fluid like beer, comprising a fitting for attachment to an aperture in a container wall, which fitting comprises a valve assembly for enabling ingress and egress of fluid into and out of the container via the aperture, and a housing attachable to the wall and operably surrounding the valve assembly in use, wherein the container further comprises a fluid deflector operably located proximal the valve for deflecting fluid radially away from the aperture.
- the term keg and container are used interchangeably to denote any kind of fluid container.
- the deflector is attached to the inside of the keg wall having the aperture, for example by welding.
- the deflector comprises a substantially flat central region preferably approximately the same size as the aperture.
- the deflector preferably has outer legs extending towards the inside wall of the keg and preferably being adapted for attachment thereto for example by welding.
- the deflector can comprise a central aperture for a downtube, and a seat for the upper part (or centre-piece) of the downtube in order to locate and maintain the position of the downtube.
- the downtube can comprise suitable lugs to sit on the seat forming part of the deflector.
- an aperture is defined by the deflector between the deflector and keg wall which aperture (possibly comprising two or more sections between legs) is substantially equal if not greater in size than the cross sectional area of the inlet aperture in the fitting (ie. through the valve).
- the housing comprises a neck and flange above the apertured wall of the keg, which together with the deflector define a chamber about the valve assembly which chamber has a radial cross-sectional area at any axial position which is substantially equal to or preferably greater than the cross-sectional area of a fluid inlet aperture (12) in the flange thereby to prevent or at least mitigate retardation in the flow or velocity of fluid into the keg.
- a further aspect of the invention provides a deflector adapted to be welded to the inside of a keg.
- a further aspect of the invention comprises a keg having a neck defining an aperture for the ingress and egress of fluid into and out of the keg which neck is integrally formed with a wall of the keg.
- the neck is formed by deep drawing the keg wall about the aperture.
- FIGURE 1 is a schematic sectional side elevation view of a keg K according to the invention.
- FIGURE 2 is a schematic side elevation view of a fitting at the top of a keg substantially shown in Figure 1 ;
- FIGURE 3 is a plan elevation view from below of the fitting shown in Figure 2 in an assembled form
- FIGURE 4 is a sectional side elevation view of the fitting shown in Figures 2 and 3 in an assembled form
- FIGURE 5 is a schematic plan elevation view from below of a second embodiment of a fitting according to the invention as shown in Figure 6;
- FIGURE 6 is a sectional side elevation view of a second embodiment of a fitting and keg according to the invention.
- a keg K according to the invention comprising a top wall T having a central aperture about which is formed a neck N for a fitting F to which a connector is attached in use for filling or emptying keg K.
- Fitting F further comprises a spring S for resiliently urging a seal against a valve seat on the under side of the top flange of fitting F.
- Spring S co-operates in this regard with part (shoulder 20 described later) of a centrepiece or downtube C which facilitates removal of fluid from the keg in use.
- Keg K further comprises a deflector D for deflecting movement of fluid sideways or radially into the barrel during filling as will become apparent in relation to Figures 2 to 4.
- fitting F which comprises an upper flange 10 connected for example by welding to the upper perimeter or shoulder of a neck N formed in top wall T of keg K.
- neck N can be formed by deep drawing the top wall T about the substantially centrally disposed aperture.
- Flange 10 further comprises an aperture 12 and an outer rim 14 for attachment to a connector having feed or outlet pipes for a fluid.
- Fitting F further comprises a seal 16 which fits into a cup 18 at the upper end of spring S.
- Spring S is located against the shoulder 20 provided on centrepiece C from which project upper and lower lugs 22a and 22b respectively.
- This shoulder region 20 of centrepiece C further comprises a groove 24 for receiving a locating pin 26 at the bottom of spring S.
- Keg K further comprises a deflector D consisting principally of a plate 30 having a substantially centrally located aperture 32 about which extends a central flat region 34 having a series of slots 35 for receiving lower lugs 22b.
- An angled region 36 extends away from central region 34 to a series, in this case three, legs which extend between the deflector plate and the inside surface of top wall T, whereat the deflector and top wall can be welded together for example.
- regions 34 and 36 of deflector D provide a sealed plate of substantially equal cross sectional area to the radial cross-section of the chamber CH below flange 10. Additionally, the diameter of neck N and distance between flange 10 and deflector D enable a relatively large chamber CH to be provided thereby enabling smooth transfer of fluid between an inlet pipe (not shown) and the main body of the keg.
- the apertures A provided between the legs 38 of deflector D assist together with regions 34 and 36 of the deflector plate to deflect incoming fluid in the direction of arrows L, that is radially away from the fitting.
- the fitting F shown in Figures 2 to 4 enables a single speed or pressurised transfer to take place thus avoiding the need for stepped speed of transfer.
- the filling time can be reduced for a 50 litre keg by up to 30% if full speed is used instead of filling in stages. Accordingly, full flow of fluid can be achieved at all times in the filling of keg K according to the invention.
- FIG. 5 and 6 A further embodiment of the invention is shown in Figures 5 and 6 wherein in this embodiment the keg and fitting comprise substantially similar components to those shown in Figures 2 to 4 and accordingly like components are labelled using the same two digit reference number prefixed with the number 1.
- an open ended cylindrical neck N is provided having a rebated lower end 113 for attachment to the rim of the aperture formed in top wall T of the keg, for example attachment can be by welding. Further, the upper rim 111 of neck N is adapted for attachment to the under side of flange 110 again for example by welding into a rebated shoulder for example.
