A fluid applicator designed for liquid, cream, or lotion products is easily adaptable for oval shaped containers and other shaped heads, including circular containers. An inner housing is inserted into an outer housing with covering material, such as fabric and/or foam, located between the two housings. The covering material is tightly secured by the two housings. The two housings are permanently attached, preferably by sonic welding to form a subassembly. The inner housing may be formed with or without a domed top surface. A foam pad may be placed over the container's orifice, held in place by a covering material that is placed over the foam pad. Alternatively, depending upon the product dispensed, the foam and fabric covering material elements may be eliminated and replaced by a domed plastic insert with an array of multiple apertures to deliver high viscosity products.

Thus, having described the invention, what is claimed is: 1. A dispensing head comprising: an inner housing including: an inner housing top end; an inner housing bottom open end; a central passageway within said inner housing top end having a predetermined diameter to regulate product flow therefrom, said central passageway opening to an applicator pad; and an inner housing peripheral lip at said inner housing top end having a peripheral ridge or groove; an outer housing including; an outer housing top open end; an outer housing bottom open end; and an outer housing peripheral annular lip at said outer housing top open end inwardly facing toward the center of said outer housing and having a peripheral land area for receiving a peripheral energy director of said inner housing, said outer housing peripheral annular lip in direction of said outer housing bottom open end, said outer housing including an annular ridge or groove at said outer housing bottom open end for attachment to a receiving annular groove or ridge on a product-filled container; said applicator covering fixed between said inner housing and said outer housing, and placed over said central passageway; wherein said inner housing is slideably fixed within said outer housing such that said applicator covering is held between said housings when said inner housing peripheral lip is mated with and secured to said outer housing receiving peripheral lip. 2. The dispensing head of claim 1 including said inner housing and said outer housing having a non-circular shape. 3. The dispensing head of claim 2 including said inner housing and said outer housing having an oval shape. 4. The dispensing head of claim 1 further comprising a foam pad secured underneath said applicator covering. 5. The dispensing head of claim 1 wherein said inner housing includes a top surface having said central passageway located approximately at said top surface center. 6. The dispensing head of claim 5 including splines or ridges located along said top surface of said inner housing for directing fluid flow, said splines or ridges extending outward from said central passageway. 7. The dispensing head of claim 1 including said outer housing having a dome shaped top surface comprising a plurality of apertures. 8. The dispensing head of claim 7 wherein said inner housing top surface is dome shaped having said dome face outward through said outer housing top open end. 9. The dispensing head of claim 1 including attachment between said inner housing peripheral lip and said outer housing peripheral annular lip, wherein said attachment comprises teeth and groove mating, sonic welding, thermal bonding, or adhesive. 10. The dispensing head of claim 1 further comprising: a hollow cylindrical receptacle having an axial length and a bottom ridge, centered about said central passageway, and attached to said inner housing top end; a spring valve disposed within said receptacle, securably fixed in position by said receptacle bottom ridge, having a closed end or cap to seal said central passageway, said spring valve including vertically winding spring coils, yieldable or compressible in a longitudinal direction about said receptacle's central axis, such that a relaxed length of said spring valve is greater than the axial length of said cylindrical receptacle, said spring valve forming an annular ring orifice with said central passageway for product flow when compressed during application. 11. An applicator for dispensing fluid to a surface comprising: an oval shaped container having a top orifice with a first annular ridge or groove and a shoulder with at least one annular ridge or groove, for mating with a dispensing head; said dispensing head including: an oval shaped outer housing having a corresponding outer housing annular groove or ridge for mating with said at least one annular ridge or groove on said shoulder of said container, said outer housing having an inwardly facing top lip; an oval shaped inner housing slideably inserted within said outer housing and having contact with said inwardly facing top lip, said inner housing having an inner housing annular groove or ridge for locking into and securing to said container top orifice for sealing said inner housing to a neck portion of said container, said inner housing having a central passageway of predetermined diameter to regulate product flow therethrough; a covering material adapted to serve as a reservoir for the product and promote product flow during application, said covering material wedged and held securely between said inner and outer housings when said housings are fixably attached; securing said housings together with said covering material wedged therebetween; wherein said housings include at least one mating ridge and groove to form an attachment when said inner housing is slidably inserted within said outer housing. 12. The applicator of claim 11 including a foam pad for occluding product, located underneath said covering material. 13. The applicator of claim 12 comprising said inner housing having a dome shaped top surface, said dome outwardly facing through said outer housing when said housings are fixably attached. 14. The applicator of claim 13 including a plurality of apertures located throughout said dome shaped top surface for promoting product flow. 15. The applicator of claim 11 wherein said top orifice is located on said neck portion of said container, centered about and protruding from said shoulder. 16. The applicator of claim 11 wherein said inner housing further includes: a hollow cylindrical receptacle having an axial length and a bottom ridge, centered about said central passageway, and attached to a top end of said inner housing; a spring valve disposed within said receptacle, securably fixed in position by said receptacle bottom ridge, having a closed end or cap to seal said central passageway, said spring valve including vertically winding spring coils, yieldable or compressible in a longitudinal direction about said receptacle's central axis, such that a relaxed length of said spring valve is greater than the axial length of said cylindrical receptacle, said spring valve forming an annular ring orifice with said central passageway for product flow when compressed during application. 17. A dispensing head comprising: an inner housing including: an inner housing top end; an inner housing bottom open end; at least one aperture within said inner housing top end, having a predetermined diameter to regulate product flow therefrom; and an inner housing peripheral lip at said inner housing top end having a peripheral ridge or groove; an outer housing including: an outer housing top end; an outer housing bottom open end; a plurality of apertures within said outer housing top end, each having predetermined diameters to regulate product flow therefrom; and an outer housing peripheral annular lip at said outer housing top open end inwardly facing toward the center of said outer housing and having a peripheral land area for receiving said inner housing peripheral energy director, said outer housing peripheral annular lip in direction of said outer housing bottom open end, said outer housing including an annular ridge or groove at said outer housing bottom open end for attachment to a receiving annular groove or ridge on a product-filled container; wherein said inner housing is slideably fixed within, and secured to, said outer housing.
