ABSTRACT:
An outlet stopper includes a cap part made of a resin and having a cylinder which has a screw thread on a side face thereof, and an outlet part made of a resin and having a disk flange which has a bottom face thereof coated with an adhesive. The disk flange has a hole at a center portion thereof. The outlet part has another cylinder which is placed on top of the disk flange and has a screw thread on a side face thereof which fits the screw thread on the cylinder in the cap part. An opening blade is fixed to the inside of the cap part, and a stopping ring which has a protrusion projected outward therefrom has a break therein for opening the ring and for stopping the insertion of the cap part and the outlet part into each other before reaching a fully screwed-in position. The outlet stopper can be easily attached with the adhesive to a package commercially available in a pouch form. By attaching the outlet stopper, packages made of soft plastic bags can be handled in the same manner as rigid packages having an outlet stopper, such as hard bottles. Thus, a major drawback of packages of a pouch form can be eliminated.
