Package for liquid or solid materials

Claim 1

A pack for containing liquid or solid filling materials, comprising a flexible bag impervious to the filling material and accommodated, with its upper end folded over, within a supporting covering of parallelepipedal form which is flexible but sufficiently rigid to support the bag and formed of side walls, a base and a top, the top and one of the side walls each having two angular folding lines, the top being made in one piece and having an outwardly directed peripheral rim for attachment to the adjacent exterior portions of the side walls of the covering so as to act as a reinforcement for the upper edges of the side walls and a portion of the rim and the adjacent wall to which this portion is attached each having mutually facing lines of weakness defining a tear-off strip between which the extremity of a folded tab of the bag is gripped, the arrangement being such that said tab can be worn away simulteneously with the tearing away of the strip formed by the lines of weakness to obtain an opening in the covering at the junction of the top and said one side wall and a double pouring spout can then be formed by urging the other two opposite side walls toward each other.
