A flexible container of the pouch type, made of material in film form, derived from a contoured tubular body formed by a film with longitudinal and transverse heat-seals of the two ends. The longitudinal heat-seal forms the edge of a longitudinal wing that is folded against the corresponding wall. A portion of the wing is joined to a corresponding portion of the wall with low-tack adhesive so as to surround a region preset to form a hole for access to the container, the first lifting of the wing opening the hole and the container, and the low-tack adhesive ensuring successive repeated opening and closure actions.

1. A flexible container derived from a contoured tubular body, formed by a film with a longitudinal heat-seal and with transverse heat-seals at two opposite ends thereof, comprising: a longitudinal wing with an edge thereof formed by the longitudinal heat-seal, that is folded along a folding line against a corresponding wall of said body, a portion of said wing being joined to a corresponding portion of said corresponding wall; a hole for accessing the container; a low-tack adhesive for joining said wing corresponding wall portions to each other and provided so as to surround a region preset to form said hole, and wherein a first lifting of said wing opens said hole and therefore the container, said low-tack adhesive being of a type that provides for successive repeated openings and closures of said wing.2. The container of claim 1, further comprising a prescoring line adapted to form said hole, said portion of said wing being rigidly coupled to said corresponding portion of the wall, said prescoring line forming a contour that surrounds at least partially said corresponding wall portion, and said low-tack adhesive being arranged at said corresponding wall portion, outside of said prescoring line contour, a first lifting of said wing tearing said corresponding wall portion and opening said hole of the container.3. The container of claim 1, wherein said portion of said wing is coupled to said corresponding portion of the wall that surrounds said hole, said low-tack adhesive being placed in a region of said corresponding wall portion that surrounds said hole, a first lifting of said wing opening said hole of the container.4. The container of claim 2, wherein said portion of said wing is coupled to said corresponding wall portion in said region preset to form said hole for accessing the container by sealing means, preferably selected from adhesive, and heat-sealing means.5. The container of claim 2, wherein said prescoring line is a preliminary die-cut.6. The container of claim 1, wherein said longitudinal heat-seal is provided only at an outermost region of said longitudinal wing.7. The container of claim 1, wherein said corresponding wall portion that surrounds said region preset to form the hole for accessing the container has a substantially quadrangular shape and is surrounded on three sides by said low-tack adhesive, a fourth side thereof corresponding to the folding line of said longitudinal wing with respect to the corresponding wall of said body.
