  • Patent number: 4112942
    Abstract: A device for introducing aqueous compositions, especially those containing medicaments, in the form of a foam to a body cavity such as the colon or vagina, comprising a plastic container having a resilient deformable body portion, a dispensing end adapted to engage with the opening of the body cavity and a second end adapted to engage with a one-way valve assembly. When the container is partially filled with a foamable composition and a one-way valve assembly is attached foam may be expelled from the dispensing end into the body opening by squeezing the container body and on releasing the squeezing action air enters through the one-way valve assembly so that the container resumes its original shape ready for a further cycle of squeezing and reinflation.
