Abstract: A flat sealed sachet includes two sheets sealed along their edges to define a cavity therebetween. The cavity encloses one of a liquid, a pasty and a powder product. A sealing strip is defined by the sealed edges of the two sheets. A nose portion extends between the cavity and the sealing strip. A loop-shaped slit is disposed in the sealing strip and extends through the two sheets. The loop-shaped cut surrounds the nose portion and defines a horse hoof-shaped portion. The horse hoof-shaped portion is selectively separable from the sealing strip to define an orifice.
