Patent ID: 7476220

Claim:
A collecting bag for human body wastes, comprising: a bag member including at least two outer film blanks with joined edges defining the outer contours of the bag member, said outer contours defining a fluid-retaining area of said bag member; an inlet opening provided in one of said film blanks; a discharge portion at a distance from the inlet opening, in a lower portion of the bag member, including a closure device for bringing the bag from a discharge position, in which the bag is open, to a position of use, in which the bag is closed, the discharge portion defining a longitudinal direction; an accommodating element within the outer contours of the bag member for accommodating at least a part of the discharge portion in the position of use of the bag; at least a first substantially tubular inner film element and a second substantially tubular inner film element, each substantially tubular inner film element being within said fluid-retaining area of said bag member and attached to the inner side of each outer film blank by means of at least one joint, said first and second substantially tubular inner film elements being respectively situated on each side of a dividing line substantially parallel with the longitudinal direction defined by the discharge portion, each of said substantially tubular inner film elements having, when the bag is substantially empty, a distal fold and a proximal fold with respect to said dividing line; a first joint between the first substantially tubular inner film element and one outer film blank and a second joint between the second substantially tubular inner film element and said one outer film blank each respectively including at least one proximal joint section at or near the proximal fold and at least one distal joint section at or near the distal fold, for each of said first and second joints a first distance between at least a lower part of the proximal joint section and the proximal fold being smaller than a second distance between at least a lower part of the distal joint section and the distal fold; said accommodating element providing at least one opening for receiving at least a part of the discharge portion in the position of use of the bag, said opening extending substantially transversely between the proximal joint sections of the first and the second substantially tubular inner film elements, respectively; and said proximal joint sections defining a recessed space therebetween that overlies the longitudinal dividing line, said recessed space being in the lower portion of the bag adjacent said discharge portion and fully accommodating said closure device in the in-use position so that said closure device when received within said opening does not protrude outside an arched plane defined by an overall shape of said bag member.
