Abstract
A fluid substance container including a collar featuring a passage and a pair of laminated film sheets heat-welded along perimetral welding lines so as to form a bag, the pair of sheets also being heat-welded to the collar so that the passage in the collar provides access to interior of the bag; the collar features a cup-shaped part in which the passage is formed, there being a sealing lip extending from a bottom of the cup-shaped part, the sealing lip being formed integrally with the collar and intended to cooperate in an air-tight manner with an outer surface of the body of a hermetic pump which may be housed, at least partially, in the collar.

A container of a fluid, comprising:
- a collar having a passage, and
- a pair of laminated film sheets thermally bonded along perimetral welding lines so as to form a bag, the pair of sheets being also thermally welded to the collar at a welding zone so that the passage of the collar defines an access inside the bag;
- wherein the collar includes a cup-shaped part having a bottom through which said passage extends, the bottom of the cup-shaped part being arranged proximate an upper end of the welding zone;
- a sealing lip extending from the bottom of said cup-shaped part, the sealing lip being integrally formed with the collar, the sealing lip cooperating in an air-tight manner with an outer surface of the pump body of an airless pump that may be housed at least partially in the cup-shaped part;
- wherein the outer surface of the collar, in the welding zone with each of the sheets having, in section, an oblong conformation with two tapered ends aligned along at least one welding axis where the pair of sheets are welded together.
