A squeezable, multi-layer, structurally self-supporting container capable of dispensing a controlled amount of a liquid product. The container comprises an external layer of a polyolefin material, an internal layer formed of a polyolefin material, and an intermediate layer positioned between the external layer and the internal layer. The intermediate layer is formed of a barrier material blended with an adhesive resin and a carrier.

1. A squeezable, multi-layer, structurally self-supporting container capable of dispensing a controlled amount of a liquid product, said container comprising: an external layer, said external layer formed from a polyolefin material; an internal layer, said internal layer formed from a polyolefin material; and an intermediate layer positioned between, and in contiguous contact with, the external layer and the internal layer, said intermediate layer formed of a barrier material blended with an adhesive resin and a carrier. 2. The container of claim 1 wherein the external layer is selected from the group consisting of polyethylene, polypropylene, and blends thereof. 3. The container of claim 2 wherein the external layer is low-density polyethylene. 4. The container of claim 1 wherein the internal layer is selected from the group consisting of polyethylene, polypropylene, and blends thereof. 5. The container of claim 4 wherein the internal layer is High-density polyethylene. 6. The container of claim 1 wherein the intermediate layer comprises from about 10% to about 30% by weight barrier material, from about 5% to about 10% by weight adhesive, and from about 60% to about 85% by weight carrier. 7. The container of claim 6 wherein the intermediate layer comprises approximately 30% by weight barrier material, 10% by weight adhesive, and 60% by weight carrier. 8. The container of claim 1 wherein the barrier material is ethylene vinyl alcohol. 9. The container of claim 1 wherein the adhesive resin is an anhydride-modified polyolefin. 10. The container of claim 9 wherein the adhesive resin is selected from the group consisting of anhydride-modified polyethylene, anhydride-modified high-density polyethylene, anhydride-modified linear low-density polyethylene, anhydride-modified low-density polyethylene, and anhydride-modified polypropylene. 11. The container of claim 1 wherein the carrier is low-density polyethylene. 12. The container of claim 1 wherein said liquid product is an adhesive. 13. The container of claim 1 wherein said liquid product is a cyanoacrylate adhesive. 14. A method of forming a squeezable, multi-layer, structurally self-supporting container capable of dispensing a controlled amount of a liquid product, comprising: a) forming a parison including; an external polyolefin layer; an internal polyolefin layer; and an intermediate layer positioned between, and in contiguous contact with, the external layer and the internal layer, said intermediate layer formed of a barrier material blended with an adhesive resin and a carrier; and b) blow-molding the parison into the desired container shape. 15. The method of claim 14 wherein the barrier material, the adhesive resin, and the carrier are blended together in a dry state to form a single mixture. 16. The method of claim 14 wherein the intermediate layer comprises from about 10% to about 30% by weight barrier material, from about 5% to about 10% by weight adhesive, and from about 60% to about 85% by weight carrier. 17. The method of claim 16 wherein the intermediate layer comprises approximately 30% by weight barrier material, 10% by weight adhesive, and 60% by weight carrier. 18. The method of claim 14 wherein said liquid product is an adhesive. 19. The method of claim 14 wherein said liquid product is a cyanoacrylate adhesive.
