Abstract
A syringe and method for use in propelling an effervescing liquid mixture for purposes of hygienic irrigation. A pre-charged liquid mixture is stored in a container having a sealable cap. When the container is shaken, gas is released from the mixture so as to pressurize the container. The mixture can then be propelled in an effervescing state to a fountain nozzle when the container cap is moved to release the cap seal.
Claims11
A hygienic syringe for dispensing a hygienic liquid mixture in an effervescing state comprising a container having a neck portion extending therefrom, a hygienic liquid mixture within said container having a gas dissolved therein when said hygienic liquid mixture is stored within said container in a pre-charged condition, said hygienic liquid mixture reaching an effervescing state when said dissolved gas is released therefrom by sufficient disturbance of said precharged condition of said hygienic liquid mixture within said container, a cap constructed and arranged to movably engage said neck portion and having a cap opening therein to communicate the hygienic liquid mixture in said container to a dispensing location, and sealing means on said neck portion and responsive to movement of said cap for preventing said hygienic liquid mixture in said pre-charged condition from entering said cap opening when said cap is in a first position and for enabling said hygienic liquid mixture when in said effervescing state to be propelled out of said container through said cap opening in response to pressure developed within said container by said released gases when said cap is in a second position.
A sealable cap for dispensing liquid contents within a container having a neck portion extending therefrom, said neck portion having an outlet opening for passage of said liquid contents at one end thereof, said cap being constructed and arranged to movably engage said neck portion and including a conduit projecting downwardly therein, said conduit having an opening extending therein from the outside of said cap and terminating adjacent said outlet opening at an end wall at the bottom of said conduit, said end wall sealingly engaging said outlet opening in said neck portion when said cap is in a first position relative to said neck portion, said conduit also having at least one aperture extending therethrough in the vicinity of said end wall for communicating said liquid contents from said outlet opening to said conduit opening when said cap is in a second position relative to said neck portion.
A method for dispensing a hygienic liquid mixture in an effervescing state to cleanse a predetermined body area comprising the steps of forming a hygienic liquid mixture in a pre-charged condition by placing a hygienic liquid inside of a container and dissolving a predetermined quantity of gas therein, sealing said container while retaining said hygienic liquid and said gas dissolved therein in said pre-charged condition, thereafter shaking said container to sufficiently disturb said pre-charged condition such that a portion of said dissolved gas is released therefrom to develop a sufficient pressure within said container to provide said hygienic liquid mixture in an effervescing state, promptly opening said container proximate said predetermined body area, thereby propelling said hygienic liquid mixture through said opening and out of said container in said effervescing state in response to the pressure developed by said released gas, to cleanse said predetermined body area.
