DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a pouring device and in particular to a pouring device for use with a liquid container.
It is well known that it is difficult to obtain a smooth flow of liquid from a container having a single outlet. The outflow of liquid from the container creates a low pressure zone within the container. As a consequence of this, air is forced into the container through the liquid passing through the outlet and in so doing creates a surging or gulping effect. This surging effect disrupts the outflow producing an unstable jet of liquid.
In normal circumstances, such an unstable jet of liquid is merely inconvenient. However, when corrosive, toxic or flammable liquids are being poured from a container such an unstable flow can be dangerous.
In my earlier European Patent Specification No. 0047757 there is disclosed a pouring device which is provided with a pair of opposed legs which generally conform to the shape of the container outlet and are deformed inwardly when the device is fitted into a container outlet. The device also comprises a body portion having an aperture therethrough and an air flow tube in communication with the aperture. In use, a free end of the air flow tube is disposed within the container.
The present invention aims to provide an improved pouring device.
Accordingly, the present invention provides a pouring device for positioning in an outlet of a container, the pouring device comprising a tubular body which is arranged to be locatable in the container outlet and a series of breather tubes which are mounted around an end of the tubular body and extend away from the tubular body, the breather tubes being movable from a first position, at which the breather tubes are substantially axially aligned with the tubular body to a second position, at which the breather tubes are inclined to the axis of the tubular body.
Embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings, in which:
FIG. 1 is a plan view of a pouring device in accordance with a first embodiment of the present invention;
FIG. 2 is a sectional side view of the pouring device of FIG. 1 when inserted into a container outlet and with the breather tubes being aligned with the tubular body;
FIG. 3 is a sectional side view, similar to FIG. 2, wherein the annular wall of the pouring device has been flexed so as to dispose the breather tubes against the upper wall of the container;
FIG. 4 is a sectional side view, similar to FIG. 3, showing the pouring device in operation when liquid is being poured from a container;
FIG. 5 is a sectional side view of a pouring device in accordance with a second embodiment of the present invention, the pouring device being mounted in a closure for a container, the pouring device being partly inserted into a container outlet;
FIG. 6 is a sectional side view of the pouring device of FIG. 5 when fully inserted into a container outlet;
FIG. 7 is a sectional side view of a pouring device in accordance with a third embodiment of the present invention;
FIG. 8 is a sectional side view of a pouring device in accordance with a fourth embodiment of the present invention, the pouring device being partially inserted into a container outlet;
FIG. 9 is a sectional side view, similar to FIG. 8, wherein the pouring device has been fully inserted into a container outlet;
FIG. 10 is a sectional side view of a pouring device in accordance with a fifth embodiment of the present invention, the pouring device being fully inserted into a container outlet;
FIG. 11 is a sectional side view of a pouring device in accordance with a sixth embodiment of the present invention, the pouring device being inserted into a container outlet and with the breather tubes being aligned with the tubular body;
FIG. 12 is a sectional side view, similar to FIG. 11, wherein the annular wall of the pouring device has been flipped so as to incline the breather tubes relative to the axis of the tubular body;
FIG. 13 is a sectional side view of a pouring device in ac
