A bag for containing pills or medication for example, is made of a heat-weldable sheet material. The sheet material may suitably be a compound sheet material which provides a rear face, a front face and a bottom. Disposed at an upper portion of the bag is a threaded closure comprising a screw-threaded socket and a screw cap. The socket penetrates the top of the bag and is bonded to the interior surface of the bag. The threaded closure permits the bag to be repeatedly opened and closed for piecemeal dispensing its contents.
