1. A container for storing and dispensing products, said container comprising:
a flexible body for dispensing a single dose of said product, said body having a first end and a second end and a first side wall and a second side wall, and defining an interior cavity sealable at the first end by joining a first inner side of the first side wall, said first inner side being the inner surface of said body, to an opposite inner side of the second side wall, said opposite inner side being the inner surface of said body; said second end of the body being neckless and threadless and having a shoulder, a lip and a protuberance, said lip formed by an overlap of each of the first side wall and the second side wall at the shoulder, resulting in the lip forming a rounded edge; said protuberance defining a dispensing orifice and having a generally flat sealing edge, wherein said sealing edge defines an outer ring of the dispensing orifice; a seal membrane shaped to overlie the sealing edge and to cover said dispensing orifice; a tab portion extending from said seal membrane and extending radially downwardly away from the protuberance and along the shoulder; wherein said seal membrane is removably affixed to said sealing edge; wherein a cap is not provided at said second end to cover seal membrane; wherein the protuberance is of insufficient height to accommodate threads; wherein said dispensing orifice has a diameter between 5% and 65% of the total diameter of the surface of the shoulder, and said dispensing orifice has a diameter less than half a radius of said sealing edge, thereby providing with the sealing edge and seal membrane, a surface upon which said container can stand, upright; and wherein said container is single use.
