A dispensing device, comprising: a container maintaining a material to be dispensed; and a two piece pump mechanism constructed of: a first piece having a dome button and a top portion of an exit pathway integrally formed with said dome button , said dome button being received by said container; a second piece having a base plate and a bottom portion of the exit pathway integrally formed with said base plate , said base plate having an aperture therethrough allowing communication between said dome button and an interior of said container ; and a first valve comprising a flap of material integrally connected to the first piece and selectively positionable over said aperture ; wherein depression of said dome button activates said first valve so that said flap of material closes said aperture to cause passage of material from said dome button and through said exit pathway formed by the top portion and the bottom portion mated together, characterized in that : said flap of material is spring biased in such a fashion to be slightly open when at rest so that material may return to said container and not exit through said exit pathway , in the form of leakage, when pressure is accidentally placed on said dome button in an amount less than that necessary to close the aperture . a container maintaining a material to be dispensed; and a two piece pump mechanism constructed of: a first piece having a dome button and a top portion of an exit pathway integrally formed with said dome button , said dome button being received by said container; a second piece having a base plate and a bottom portion of the exit pathway integrally formed with said base plate , said base plate having an aperture therethrough allowing communication between said dome button and an interior of said container ; and a first valve comprising a flap of material integrally connected to the first piece and selectively positionable over said aperture ; wherein depression of said dome button activates said first valve so that said flap of material closes said aperture to cause passage of material from said dome button and through said exit pathway formed by the top portion and the bottom portion mated together, characterized in that : said flap of material is spring biased in such a fashion to be slightly open when at rest so that material may return to said container and not exit through said exit pathway , in the form of leakage, when pressure is accidentally placed on said dome button in an amount less than that necessary to close the aperture . a first piece having a dome button and a top portion of an exit pathway integrally formed with said dome button , said dome button being received by said container; a second piece having a base plate and a bottom portion of the exit pathway integrally formed with said base plate , said base plate having an aperture therethrough allowing communication between said dome button and an interior of said container ; and a first valve comprising a flap of material integrally connected to the first piece and selectively positionable over said aperture ; wherein depression of said dome button activates said first valve so that said flap of material closes said aperture to cause passage of material from said dome button and through said exit pathway formed by the top portion and the bottom portion mated together, characterized in that : said flap of material is spring biased in such a fashion to be slightly open when at rest so that material may return to said container and not exit through said exit pathway , in the form of leakage, when pressure is accidentally placed on said dome button in an amount less than that necessary to close the aperture . <EOS>
