摘要： PURPOSE:To protect bagged contents from external shocks by forming an opening portion of a double walled bag with the inner and outer walls adhered together at one end thereof, providing a liquid pouring opening between joint faces of the inner and outer walls, inserting the content from the opening portion, and pouring liquid into between the inner and outer walls from the liquid pouring opening to wrap and retain the content by the inner wall. CONSTITUTION:A double walled tubular bag is formed of a gas impermeable, flexible outer tubular wall 1 and an inner tubular wall 2 of the material identical to the former material inserted therein. One end of the bag is adhered together to form a seal portion 3 and, at the other end, the inner tubular wall 2 and the outer tubular wall 1 in adjacent relationship are adhered together to form seal portions 3', 3' and an opening portion 4. A liquid pouring opening 5 is provided between joint faces of the inner tubular wall 2 and the outer tubular wall 1 to pour liquid into between these walls. Content B is inserted into a double walled bag A from the opening portion 4. On liquid feed from the liquid pouring opening 5, the outer tubular wall 1 becomes swollen and the inner tubular wall 2 holds the content B in a sandwiched condition, as if retaining the content B in floating position in relation to the outer tubular wall 1. The content B can be easily removed from the opening portion 4 of the bag by pouring liquid out of the liquid pouring opening 5.
