Definitions

  • the present invention relates to an apparatus for making foam, such as a toy for making foam from a foaming agent such as soap or detergent.
  • foaming agent such as bath foam
  • foam aerosols are available in which foam is dispensed from a nozzle on a pressurised container, but the container does not form part of a toy.
  • foam making apparatus comprising a housing having a foam outlet; a gas permeable store mounted in the housing for storing a supply of foaming agent; and an activator for causing gas to pass through the store so as to generate a supply of foam in the housing which can be expelled through the foam outlet.
  • the invention seeks to provide a toy which self-generates foam by the action a child playing with the toy whereby amusement is had with both playing with the toy and playing with the foam.
  • the invention provides a very simple form of apparatus which is particularly suited for use by children as a toy such as a bath toy.
  • the gas will comprise air allowing the foam very safely to be generated.
  • the apparatus may further comprise a liquid inlet to enable liquid to enter the housing and mix with the foam so as to dilute the foam.
  • the store could be fixed in the housing, the activator causing gas to pass through the store.
  • the store is movable within the housing under control of the activator to cause gas to pass through the store.
  • the store and housing may form a piston/cylinder arrangement.
  • the store in the form of a piston reciprocates in and out of the cylinder, reciprocation of said piston forcing gas, e.g. air, through the store as said piston reciprocates out of the cylinder.
  • the activator is also adapted to cause foam to be expelled through the foam outlet.
  • the piston can expel foam out of the housing.
  • a one-way valve is provided in one or both of the foam outlet and liquid inlet (where provided) to ensure correct operation of the apparatus.
  • the store is preferably a porous membrane which may be an open foam structure such as a sponge or sponge-like structure.
  • the diluting liquid may be water and the gas may be air.
  • the foaming agent may be a soap or detergent or similar agent, such as commercial foam bath liquid.
  • the foam outlet may have a non-circular cross-section so as to form a mould to shape the foam expelled therethrough.
  • an apparatus 1 having a housing 2 in the form of a cylindrical tube having an open end 3 and a closed end 4. Closed end 4 has a one-way valve 5 in the form of a hinged flap 6 hinged to the inside of the end 3, and an aperture 7 covered by the flap 6 in its closed position.
  • a housing or foam outlet is provided by a spout 8 extending from the housing wall.
  • a spout 8 Inside spout 8 is a one-way valve 9 in the form of a hinged flap 10 hinged to the inside of the spout, which flap 10 seals against a seat formed by an annular rib 11.
  • a piston arrangement 12 is formed by a hollow tubular shaft or actuator 13 having a handle 14 at one end thereof, and a gas-permeable sponge membrane 15 at the end of the shaft 13 remote from the handle 14.
  • the piston 12 can be made to reciprocate into and out of the housing 2.
  • the closed end 4 of the apparatus can be immersed in water as shown.
  • the one-way valve 9 closes, and the air pressure in the housing 2 reduces, and thus air is forced through membrane 15. Withdrawal of the piston arrangement 12 thus provides a gas generating means.
  • a small amount of water enters the housing through the one-way valve 5, so that the water level in the housing is the same as the level outside the housing.
  • a foaming agent such as soap or detergent is applied to and stored in the membrane 15 in either a concentrate or diluted form.
  • the membrane 15 is in contact with and absorbs the water which has entered the cylinder through the one-way valve 5.
  • the water mixes with the foaming agent.
  • the one-way valve 5 thus provides a means for applying diluting liquid to the foaming agent.
  • the piston arrangement 12 is drawn towards the end 3 of the housing 2, air is forced through the membrane 15 containing foaming agent and water and creates a plurality of foam or "bubbles" 16.
  • the apparatus may be used as a toy.
  • Suckers (not shown) may be provided to attach the apparatus to the wall of a bath with the end of the housing immersed in the bath water.
  • the apparatus could be shaped into the form of a character or other object such as a pump. It could be of any suitable colour and made of any suitable material such as moulded plastics.
  • the outlet 8 may form a mould to shape the foam expelled therethrough.
  • dies could be attached to the end of spout 8, such as triangular, square or other shaped dies.
  • the outlet 8 may be designed to expel balls of foam and the apparatus may be designed to imitate a gun which shoots such foam balls.
  • a spring such as a coil spring, could bias the piston out of the housing 2. The user would then only be required to push the piston into the housing and the spring would return the piston out of the housing.
  • the membrane 15 may be a push fit in the cylinder 2 thus allowing it to be completely withdrawn for recharging with foaming agent. Alternatively, it may be retained in the housing via a flange (not shown) or other retaining member at the end 3.
  • the invention extends to any apparatus in which gas is forced through a membrane containing a foaming agent.
  • gas such as air could be provided by an electric pump.
