Definitions

• the present invention relates to a filling spout for connection to the outlet of a container for liquids, the spout including a connection means for the connection and a discharge tube with inlet and outlet openings.
• a filling spout of the kind mentioned is used to avoid unnecessary splashing when filling different objects from a reserve can or the like.
• the jet of liquid can be more easily guided and the tube can also optionally be inserted in existing inlet openings.
• Known devices of this type are available as accessories to reserve petrol cans, for example, the connection means usually consisting of a screwed sleeve for screwed connection to the outlet of the can.
• the filling operation itself can most usually be carried out without leakage, but on the other hand, the risk is still very great that spillage will occur at the start and finish of the operation.
• a filling spout in accordance with the invention is arranged so that the outlet opening can be easily opened or closed by manually displacing a sealing tube placed round the discharge tube.
• the outlet opening is made radially in the wall of the discharge tube, which means that this valve arrangement can be made very simple without risking leakage.
• the manual displacement of the sealing tube is facilitated by an abutment arranged to engage against some inlet or the like on the object to be filled.
• Seals are suitably arranged between the discharge tube and sealing tube as well as on the connection means to provide an air and liquid tight space between the liquid container and the outlet opening. This embodiment gives the possibility of automatically stopping filling when the level of liquid has reached the outlet opening, although with the condition that the container is completely closed.
• Figure 1 is a longitudinal section through a filling spout in accordance with the invention.
• Figure 2 is a cross section on the line 2-2 in Figure 1.
• the illustrated filling spout includes a discharge tube 11 with an inlet 12 and with an outlet opening 13 made radially in the tube wall.
• the tube end is formed as a flange 14 for facilitating connection to a connection means 15 in the form of an internally threaded muff.
• the flange 14 is here urged against an annular shoulder 16 in the middle portion of the muff, and with the aid of a sealing member 17 and internal circlip 18 carefully sealed against the muff.
• the outer 19 and inner 20 parts of the muff have a thread 21 and 22, respectively, which mates with the thread on the outlet of .an unillustrated closed container, resulting in that the spout, when it is not used, can be turned 180o in a conventional manner and directed inwards into the container.
• a sealing ring 23
• the discharge tube 11 is surrounded by a seal ⁇ ing tube 25, which is axially displaceable along the discharge tube between a first closed position illustrated in Figure 1 and a second unillustrated open position.
• the inner end 26 of the sealing tube nearest the connection means 15 is sealed against the discharge tube by a sealing ring 27, and engages against a spring means 28 in the form of a helical spring mounted around the discharge tube.
• the outer end 30 of the sealing tube which shall uncover the outlet 13 in the opening position, engages against a flange part 31 on the discharge tube in the closed position.
• the flange part 31 is formed as a part of an end plug 32 closing the outer end 33 of the discharge tube, and also forms a support for sealing ring 34.
• the end plug 32 suitably has a rounded-off inner surface to facilitate flow.
• An abutment 35 is arranged on the sealing tube 25, and is movable in some simple way along the tube so that the distance between the abutment 35 and the outer end 33 can be freely selected.
• the abutment 35 is implemented as a disc with an eccentrically made bore 36 for the sealing tube. Holes 37 for the passage of air can optionally be made in the disc.
• the latter is first unscrewed from its storage position in the associated container, turned 180 and screwed onto the outlet of the container with the aid of the connection muff 15. The container and spout then form an air and liquid tight closed space.
• the spout can be taken in an optional direction towards the inlet of the tank, without risking spillage or leakage.
• the sealed state remains until the abutment 35 reaches the inlet opening, after which a continued inward pressure of the spout results in that the abutment pulls up the discharge tube 25 towards the connection muff 15.
• the outlet opening 13 is thus uncovered and filling starts.
• the sealing tube is suitably displaceable into a given final position which can be decided by the spring 28 not being able to be compressed further than a given distance or by a special abutment being made on the discharge tube.
• the filling level in the tank can be adjusted to a suitable height.
• the spout is drawn backwards out of the tank, the spring 28 simultaneously urging the sealing tube against the flange part 31 so that the opening 13 is closed off.
• the described filling operation can thus be carried out completely without spillage or other draw- backs. Since the spout in itself is completely sealed off, it can optionally remain in the position of use, which is advantageous if the container is often used, e.g. as a petrol can in forestry work with a chain saw.
• the eccentric implementation of the abutment results in that it can thrust further in one direction to form a good abutment, while sufficient air passage is left in the opposite direction.
