A plastic film fluid storage bag and dispensing spike assembly and method wherein the spike punctures the film and forms a fluid tight seal with the film surrounding a hole formed by the puncture. The film has no separate port structure for dispensing its contents. The spike may include a bulbous body with a sharpened tip at one end, an enlarged central portion, and a reduced diameter portion at its opposite end, adjacent a radially extending skirt. When seated, a seal is created around the smaller diameter portion of the body and against the skirt. The spike may alternatively include a cylindrical body with a slightly rounded point at one end and a radially extending skirt intermediate its ends. Finally, the cylindrical body spike may be used without a skirt. In all cases, a fluid passage extends through the body.
