A sprayer is provided for preferably permanent attachment to a container containing a chemical product to be diluted by a carrier stream. The sprayer comprises a nozzle member having a mechanism for attachment of the nozzle member to a source of the carrier stream. The nozzle member also includes a control mechanism for controlling flow of the carrier stream. The sprayer also includes a control member having a product aperture and an inlet or vent port disposed therein. The sprayer further comprises a cap member, including a means for attaching the cap member to the container. The cap member is slideably attached to the control member and includes a corresponding product channel and an inlet or vent channel. Preferably, the control member and the control mechanism for controlling the flow of the carrier fluid are operatively connected such that a single motion can simultaneously open or close both the flow of carrier fluid and the chemical product.

1. An aspiration type sprayer for attachment to a container encompassing a chemical to be diluted by a carrier stream, comprising: a. a nozzle member, said nozzle member comprising a means for attachment of said nozzle member to a source of the carrier stream and a means for controlling flow of the carrier stream; b. a cap member in operative connection with said nozzle member, said cap member including a means for attaching said cap member to the container, said cap member having disposed therein a product channel and a vent channel; and c. a control member, said control member including a product aperture and a vent means disposed therein, said control member being slideably connected to said cap member such that said control member can be longitudinally slid to a first position in which said product aperture and said vent means are in substantially linear communicative connection with said product channel and said vent channel, respectfully, thereby allowing the chemical to enter the carrier stream for dilution when the carrier stream passes over the product aperture, said control member also longitudinally slideable to a second position in which said product aperture and said vent means are not in communicative connection with said product channel and said vent channel, thereby substantially sealing the chemical within the container. 2. The sprayer of claim 1 wherein said means for attaching said cap member to the container permanently attaches said cap member to the container. 3. The sprayer of claim 1 further comprising a means for operatively connecting said control member and said carrier stream flow control means to allow simultaneous control of carrier stream flow and product flow. 4. The sprayer of claim 3 wherein said control member is slideable to a third position in which said product aperture and said vent means are not in communicative connection with said product channel and said vent channel, and said carrier stream flow control means is in an open position to allow spraying of substantially pure carrier fluid. 5. The sprayer of claim 1 further comprising means for providing a substantially sealed connection between said control member and said cap member. 6. The sprayer of claim 5 wherein said seal means comprises at least one elastomeric ring. 7. The sprayer of claim 1 wherein a length between a beginning of said product channel and said product aperture is less than 1/2 inch. 8. The sprayer of claim 7 wherein said length is less than 3/8 inch. 9. The sprayer of claim 8 wherein said length is approximately 1/4 inch. 10. The sprayer of claim 3 wherein said means for operatively connecting said control member and said carrier stream flow control means comprises a gear means disposed upon said carrier stream flow control means which operates connectively with another gear means disposed upon said control member.
