Definitions

  • This invention relates to a self-emptying plug for a container of liquid which plug is provided with a valve means which, when the hydrostatic pressure increases, depresses to allow emptying of the container when the pressure reaches a certain value.
  • the word "container” is to be construed widely as meaning any vessel which can contain liquid and includes in particular bathtubs, spa baths, washing basins, laundry wash troughs and kitchen sinks.
  • the self-emptying plug according to the invention provides at least a partial solution to this problem in that it allows drainage of liquid once a given pressure is exceeded.
  • This invention provides a self-emptying plug for a container of liquid which comprises:
  • a plug body adapted to fit into a hole in a container, the plug body having a first outlet for liquid therethrough and also being provided with valve guide means;
  • valve means having a head and a stem, the stem being adapted to slide within the guide means and the head being adapted to bear against a valve seat means, as defined below;
  • valve seat means as mentioned under (c) and (d), adapted to be located between the plug body and the cap means, whereby as hydrostatic pressure in the container increases to a selected pressure, the valve head is forced out of contact with the valve seat allowing liquid to flow through the first and second outlets out of the container.
  • Fig I is an exploded view (as viewed down the page) of a first embodiment of a self -emptying plug
  • Fig 2 is a cross-sectional view of the assembled plus of Fig 1 in its "closed" configuration
  • Fig 3 is a cross-sectional view of the plug of Figs I and 2 in its "half-open" configuration

  • the plug seat may be let into the container either from its outside or its inside.
  • the plug body and the plug seat are both preferably substantially round in shape.
  • the plug body is preferably supplied with a grid through which liquid may flow, that is, the first outlet may comprise a number of holes.
  • the grid may be star-shaped having partitions extending from a central structure.
  • the valvue guide means is preferably located in the central structure.
  • the valve guide means is preferably in a hole extending through the central structure referred to above.
  • the plug cap may be of any suitable shape but is preferably provided with a lip which fits down around the plug body
  • the second outlet may take the form of a number of holes of any suitable shape let through the top of the cap, the only requirement being that the holes allow a sufficient volume of liquid to flow therethrough.
  • the spring means may be of any suitable type, for example, a helical or a spiral spring specially adapted to collapse at a selected hydrostatic pressure.
  • a specially adapted flat plate spring is another option.
  • a preferred option is a Belville spring which, in a first operative position, is conically shaped (in cross-section) outwards but can take up a flattened shape (also in cross-section), in a second operative position.
  • the valve seat means is prererably adapted to flex downwardly and follow the direction of travel downwards of the valve head.
  • it may be constructed as a flexible, flat ring which can fit over the top of the plug body, be held within the upper region of the plug cap. or be retained between the plug cap and the plug body
  • me self -emptying plug according to the invention may be provided with an override means which may be adapted to prevent opening of the valve means and/or close the valve means once open.
  • the plug body may be provided with a set of internal ramps arranged around the inside surface of the plug body These ramps are adapted to interact with a set of runner means attached to or forming pan of the valve means, whereby rotation of the valve means causes the runners to travel up the ramps forcing the valve means against the valve seat.
  • the cap may be provided with a pivoting hook or fork means which interacts with the upper end (as viewed in use) of the valve stem which may itself be suitably shaped to receive the pivoting hook or fork means.
