A packaging container which includes a synthetic resin container body having a flange part and the cover member heat-sealed to the flange part of the container body. The cover member includes (1) an upper member in which inner surfaces of resin films are positioned opposite to each other to form an abutted part, an unsealed part communicating with the inside of the container body is formed by heat-sealing a peripheral edge part of the abutted part excluding one side of the abutted part forming a base part, and the steam releasing seal part is formed at the abutted part and (2) a lower member which covers a lower surface of the upper member and in which a steam guide part communicating with the inside of the container body is formed at or near the base part of the abutted part.

An improved bag-shaped container with a straw insert hole formed thereon is disclosed. The straw insert hole extends through the body of the container and two sealing pieces are adhered to the inner surface of the body to fully close the straw insert hole. Further, a tab is disposed on the outer surface of the body to fully cover the straw insert hole. When an user wants to take the content out of the container, he first peels the tab and then causes a straw to pierce through the second sealing piece until its foremost end part is inserted into the interior of the container. Thus, he is ready to suck the content in the container. To facilitate piercing of the foremost end part of the straw the sealing piece is formed with a small hole or a weakened portion in the form of score. A method of producing bag-shaped containers with a straw insert hole formed thereon respectively is carried out by way of the steps of punching a straw insert hole on the sheet material, temporarily adhering a first sealing piece to the inner surface of the sheet material to cover the straw insert hole, temporarily adhering a tab to the outer surface of the sheet material, finally adhering the tab to the first sealing piece and adhering a second sealing piece to the inner surface of the sheet material or to the first sealing piece to cover the latter.
