The packette is formed of thin flexible plastic material and includes a container portion in which the douche concentrate is stored and a dispenser portion integral with the container portion and which is constituted by an elongated, small diameter tubular stem which has a constant transverse cross-section throughout its length and a separable terminal tip portion. The packette is openable through separation of the terminal tip portion from the dispenser portion whereupon the dispenser portion is inserted through an opening of a bottle containing a diluent so as to extend to a significant extent into the interior thereof. The concentrate is dispensed into the diluent by squeezing the container portion of the packette. An elongate nozzle is then connected to the bottle for subsequent administration of the douche solution. ## Claims ### Claim 1 Disposable apparatus for storing and dispensing the constituents of a medicated douche solution, comprising: a sealed bottle containing a predetermined amount of diluent, said bottle including a main axially extending portion and an integral substantially cylindrical connecting portion angularly extending from said main portion, said connecting portion being formed with a closure wall having means associated therewith for defining an opening therein having a diameter which is substantially equal to or less than a certain maximum value and which is substantially equal to or greater than a certain minimum value; a sealed unitary packette formed of a vinylidene chloride copolymer material containing a unit dose of liquid douche concentrate, said packette including a container portion defining an interior volume in which said unit dose of liquid douche concentrate is contained and a dispenser portion integral with said container portion and being constituted by an elongated substantially tubular stem having a substantially constant transverse cross-section throughout its length whose major dimension equals said minimum value of said bottle opening diameter, said tubular stem communicating at one end thereof with the interior of said container portion and having a separable integral terminal tip portion, said packette being openable through separation of said terminal tip portion from said dispenser portion, said tubular stem having a length greater than a certain value and an inner diameter smaller than a certain value such that upon opening said packette and inverting the same so that its open end faces downwardly, said tubular stem constitutes means for preventing the douche concentrate from freely flowing out of said packette under the effect of surface tension forces created between said stem and douche concentrate, said dispenser portion being insertable through said bottle opening so as to extend to a significant extent into the interior thereof so that the concentrate can be dispensed without spillage into the diluent by squeezing said container portion; and an elongate nozzle having a connecting portion adapted to be connected to said connecting portion of said bottle after said concentrate has been dispensed into the diluent. ### Claim 2 (depends on 1) The combination of claim 1 wherein said maximum value of said opening diameter is about 3/16 inch. ### Claim 3 (depends on 2) The combination of claim 2 wherein said minimum value is about 1/8 inch. ### Claim 4 (depends on 2) The combination of claim 2 wherein said elongated tubular stem constituting said dispenser portion has a length of at least about 0.5 inches. ### Claim 5 (depends on 4) The combination of claim 4 wherein said elongated tubular stem has an inner diameter of about 1/16 inch. ### Claim 6 Apparatus for both storing and dispensing a liquid douche concentrate into a diluent bottle through an opening therein, comprising: a sealed unitary packette formed of a vinylidene chloride copolymer material, said packette including a container portion defining an interior volume in which a unit dose of liquid douche concentrate is contained and a dispenser portion integral with said container portion and being constituted by an elongated substantially tubular stem having a substantially constant transverse cross-section throughout its length, said dispenser portion communicating at one end thereof with the interior of said container portion and having a separable terminal tip portion, said vinylidene chloride copolymer material being air impermeable and both chemically and physically stable with respect to the liquid douche concentrate, said packette being normally sealed in an air-tight manner with the concentrate stored therein and openable through separation of said terminal tip portion, said tubular stem having a length greater than a certain value and an inner diameter smaller than a certain value such that upon opening said packette and inverting the same so that its open end faces downwardly, said tubular stem constitutes means for preventing the douche concentrate from freely flowing out of said packette under the effect of surface tension forces created between said stem and douche concentrate, whereupon said dispenser portion is insertable through the opening of a diluent bottle into the interior thereof so that the concentrate can be dispensed into the diluent by squeezing said container portion without spillage. ### Claim 7 (depends on 6) The combination of claim 6 wherein said elongated tubular stem constituting said dispenser portion has a length of at least about 0.5 inches. ### Claim 8 (depends on 7) The combination of claim 7 wherein said elongated tubular stem has an inner diameter of about 1/16 inches. ### Claim 9 (depends on 6) The combination of claim 6 wherein said container portion defines an interior adapted to store about 0.18 fluid ounces of said liquid douche concentrate. ### Claim 10 (depends on 6) The combination of claim 6 wherein said plastic material comprises transparent Saran material. ### Claim 11 (depends on 10) The combination of claim 10 wherein said Saran material has a thickness of about 0.006 inches. ### Claim 12 (depends on 6) The combination of claim 6 wherein said packette is formed of extruded tubular flexible plastic material having a bottom edge band and at least one side edge band.
