1. A plastic canister for sprayers, said canister having a closed bottom end, and an open top end, and radially opposed cover engaging means integral with the outer surface of the canister adjacent the open top end, said cover engaging means each comprising a rib projecting outwardly from the canister and having an opening therethrough for receiving an engagement element of a sprayer, means for reinforcing that portion of the rib at the uppermost portion of the opening to withstand the clamping forces applied to the rib by the attachment of a sprayer cover apparatus to the canister. 2. The canister of claim 1 wherein the cover engaging means is fashioned from the flashing of the molding process for the canister. 3. The canister of claim 1 wherein the cover engaging means is positioned for universal use with the most widely available sprayer apparatus, wherein the opening comprises: a rectangular hole for receiving a sprayer cover apparatus; and wherein the reinforcing means comprises: an angled projection of plastic extending from the top of the rectangular hole for strengthening and reinforcing the upper portion of the rectangular hole to enable it to withstand the force applied when the cover apparatus is secured in place. 4. The canister of claim 1 wherein said rib extends substantially from the bottom to the top of said canister along the side thereof. 5. A canister for substantially universal use with sprayers of the type having a canister closure and canister engaging elements for securing a canister to the closure, said canister being plastic molded and having a closed bottom end, an open top end, and radially opposed engaging means on the outer surface of the canister adjacent the open top end thereof, said engaging means each comprising an elongated rib extending outwardly from the canister to be received by a respective one of the canister engaging elements of the sprayer, each of the ribs being fashioned from flashing molded integrally with the canister during molding of the canister, the rib extending elongatedly from an upper end located most proximal to the top open end of the canister at least generally towards the closed bottom end of the canister, the rib including a lower surface defined by an upper margin of an opening through the rib, the lower surface being positioned to be engaged by the respective canister engaging element for securing the canister to the closure. 6. The canister of claim 5, wherein said lower surface of each said rib is spaced in the order of about 0.529 inch below the open top end of the canister. 7. The canister of claim 5, wherein each canister engaging element comprises an arm having an opening therein facing in a given direction of relative rotation between the arm and the canister and a topmost portion of each said rib above the lower surface is angled from an axial direction of the canister in said given direction toward one of said arm openings. 8. The canister of claim 7, wherein each said rib comprises a lower portion extending from the topmost portion towards the closed bottom end in a direction generally parallel to the axial direction of the canister. 9. The canister of claim 8, wherein each said rib extends from the upper end downwardly to substantially the closed bottom end of the canister. 10. An integrally molded plastic canister for use with sprayers of the type having a canister closure and a pair of canister engaging arms for securing a canister to the closure, each engaging arm having an opening therein facing in a given direction of rotation of the canister engaging arms for rotationally receiving the canister, said canister having a closed bottom end, and open top end, and a pair of radially opposed ribs extending outwardly from the surface of the canister and formed from flashing of the molded canister, each said rib including an angled projection at the upper end thereof and a hole through the rib immediately below said angled projection for reception of a respective one of the canister engaging arms, each angled projection being angled away from an upwardly axial direction of the canister extending toward the open top end of the canister in said given rotational direction to be received within the opening in the engaging arm when the canister is engaged with the arms, each angled projection having a lower surface positioned to be engaged by the respective engaging arm for securing the canister to the closure, each said rib extending from the top of the respective angled projection downwardly along the canister for reinforcing the canister to withstand the force applied when the canister is secured to the closure. 11. A disposable molded plastic canister for substantially universal use with sprayers of the type having a canister closure and canister engaging elements for securing a canister to the closure, said disposable canister having a closed bottom end, an open top end, radially opposed outwardly projecting ribs molded integrally with the canister, said ribs defining radially opposed engaging means on the outer surface of the canister adjacent the open top end thereof, said engaging means each comprising an angled projection extending outwardly from the canister, said angled projection including a lower portion extending generally parallel to the axis of the canister, the lower edge of which comprises a lower surface of the projection and an upper portion angled upwardly from said lower portion in a given rotational direction with respect to the canister to be received by a respective one of the canister engaging elements of a sprayer, each lower surface being positioned to be engaged by the respective canister engaging element for securing the canister to the closure, said angled projection being angled for accommodating its reception by the canister engaging element and for strengthening and reinforcing the projection to withstand the force applied when the canister is secured to the closure, and said projecting ribs having a hole therethrough, the upper margin of which is defined by said lower surface of the respective angled projection, the angled projection comprising the uppermost portion of the respective rib. 12. A canister for substantially universal use with sprayers of the type having a canister closure and canister engaging elements for securing a canister to the closure, said canister having a closed bottom end, an open top end, and radially opposed engaging means on the outer surface of the canister adjacent the top end thereof, said engaging means each comprising an elongated projection extending outwardly from the canister to be received by a respective one of the canister engaging elements of the sprayer, the elongated projection having an upper end located most proximal to the top end of the canister and the projection extending elongatedly from the upper end towards the closed bottom end of the canister, the elongated projection including a lower surface provided by an opening extending through the elongated projection, the lower surface being positioned to be engaged by the respective canister engaging element for securing the canister to the closure. 13. The canister of claim 12, wherein a first portion of each projection located between the lower surface and the open top end is angled along the canister in a direction between an axial direction and a circumferential direction of the canister. 14. The canister of claim 13 wherein each projection further comprises a second portion extending down along the canister at an axial direction between the first portion and the lower surface. 15.
