Abstract: A blow molding method for molding tube containers by introducing blow air into a parison having been extruded by an extruder is disclosed, which comprises introducing blow air into the parison to shape a tube container and form a discharge outlet in part of the wall of an unnecessary portion of the tube container located lower than the cutting position of the tube container, and further continuing the introduction of blow air. The blow air may be introduced horizontally by piercing the wall of a parison having been extruded from an extruder with a nozzle for introducing blow air or vertically by introducing blow air in the axial direction of the parison. The discharge outlet is formed in part of the side wall or bottom wall of the container below a cutting position preferably as low as possible.

Abstract: A blow molding method by horizontal blow molding of piercing the wall of a parison having been extruded by an extruder with a blow nozzle is disclosed, which comprises moving forward the blow nozzle to pierce the parison, introducing blow air at least in the direction toward the bottom, i.e., opposite to the bottle neck and, after shaping of a hollow container by the blow air, forming an opening in the parison at a position in the vicinity of or above the blow nozzle-pierced portion to discharge the blow air having circulated inside the hollow container.

Abstract: An inert gas substitution method comprising blowing an inert gas into a container in the state wherein an opening of a container is covered with an inert gas substitution apparatus (5, 20) having an inert gas blow opening (7, 30), thereby substituting the inert gas within the container, and after substitution, covering the opening of the container with a cover material film (15). An inert gas substitution apparatus (5) formed with an inert gas blow opening (7) and having a plate of which bottom surface is flat. An inert gas substitution apparatus (20) having a chamber (21) of which bottom surface is open, the chamber (21) covering an opening of a container to blow an inert gas into the container.

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.

Abstract: The apparatus comprises a sealed chamber including a sterilizing section, a cooling section and a conveyor including carrier receivers and circulated through the sterilizing and cooling sections. The flat flexible packages containing substances to be sterilized are contained in rotatable carriers. With one side of the sealed chamber is provided a sealing means through which the carriers are charged and discharged into and out of the sealed chamber.
