Abstract
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.
