Bag body with fitting tool

A bag body with a fitting tool comprising:

• a bag main body which includes a storage portion for storing contents, a first film material including a first edge portion adjacent an opening of the bag main body and a second film material including a second edge portion adjacent the opening of the bag main body;
• and
• the fitting tool attached to an inner surface of the bag main body in a vicinity of the opening portion of the bag main body,
• wherein the fitting tool comprises:
• a first base material and a second base material which have a strip-shape;
• a first fitting part provided on the first base material in a longitudinal direction of a first fitting member;
• a second fitting part provided on the second base material in a longitudinal direction of a second fitting member, the second fitting part being detachably fitted to the first fitting part;
• a first extension part that extends from a first end part in a width direction of the first base material toward an outer surface side opposite to a first facing surface, on which the first fitting part is provided, the first extension part facing to the outer surface of the first base material;
• a second extension part that extends from a first end part in a width direction of the second base material toward an outer surface side opposite to a second facing surface, on which the second fitting part is provided, the second extension part facing to the outer surface of the second base material;
• a first folded portion folded at a boundary part between the first extension part and the first base material;
• a second folded portion folded at a boundary part between the second extension part and the second base material,
• wherein in each of the first base material and the second base material, a second end part is located on a side opposite to the first end part and is separated from each of the first extension part and the second extension part,
• wherein at least a part of the first extension part and at least a part of the second extension part are fixed to the inner surface of the bag main body,
• wherein each of the second end part is provided on an opening portion side of the bag main body with respect to the first end part,
• wherein, in a first state, the first fitting part and the second fitting part are detachably fitted, a first extension end of the first extension part and a second extension end of the second extension part are spaced apart a first distance, and a first angle is formed by the first base material and the first extension part at the first folded portion and a first angle is formed by the second base material and the second extension part at the second folded portion, and
• wherein, in a second state, the first fitting part and the second fitting part are detachably fitted, the first extension end of the first extension part and the second extension end of the second extension part are spaced apart a second distance greater than the first distance, and a second angle is formed by the first base material and the first extension part at the first folded portion that is greater than the first angle formed in the first state by the first base material and the first extension part at the first folded portion and a second angle is formed by the second base material and the second extension part at the second folded portion that is greater than the first angle formed by the second base material and the second extension part at the second folded portion in the first state;
• and
• in the first state and in the second state, the second end parts in the first and second base materials are positioned between the first and second fitting parts and the opening portion of the bag main body in the width direction of the first base material and the second base material.
