A bottom 6 is disposed on a lower end portion of a body 2 made of a film having barrier properties against gases. The bottom 6 is composed of a shield 7 and a reinforcement 8. The shield 7 is formed from a film having barrier properties against gases. A lower end opening of the body 2 is closed by welding an outer circumferential surface of a short cylindrical part 7A of the shield 7 to an inner circumferential surface of the body 2. An outer circumferential surface of the reinforcement 8 is welded to an inner circumferential surface of the short cylindrical part 7A. The lower end portion of the body 2 is maintained in a predetermined shape by the reinforcement 8.

It is aimed to smoothly perform engagement and disengagement of a fastener of a packaging bag and easily take out an inner content by a desired amount. For these purposes, in a packaging bag 1 with a fastener 20 in which a male fastener element and a female fastener element are attached to inner surfaces of opposing flat surface portions 2a and an opening is opened or closed by engaging or disengaging both the fastener elements, pick-up tabs 40 are provided so as to project outward at a portion corresponding to a mounting portion of the fastener 20, or near the portion. The fastener is formed to be asymmetric with respect to the center thereof so that one side largely protruded is attached so as to be directed inward of the packaging bag.

A bag includes a bag body having first and second sides (11c, 11d) to meet each other, and a third side (11e) extending obliquely to the first and second sides (11c, 11d) and defining an opening; a spout unit (13) having an apex (13a) projecting from the third side and defining a corner, and a zipper (15); and a recessed portion (17A, 17B, 18A, 18B) positioned away from the zipper (15) and formed on at least one of the first and second sides (11c, 11d).

A ring-like reinforcement part 2 is secured to an upper end face of a bottomed cylindrical container main body 1. The container main body 1 is formed of a flexible film-like member which is composed of polyethylene, polypropylene or the like. The reinforcement part 2 has strength enough to prevent the container main body 1 from greatly deformed and to prevent liquid, such as adhesive agent, coating material or the like stored in the container main body 1 from overflowing when the container main body 1 is lifted up through the reinforcement part 2.

A bottom 8 of a container 1 is elastically deformable between a downwardly convex state and an upwardly convex state. The bottom 8 has strength enough not to be deformed from the upwardly convex state to the downwardly convex state by a weight of granular materials filled in the container 1 and vibrations acting on the granular materials.

A storing container has a container body having a storage part and a bottom, the storage part having an opening in a distal end of the storage part, the bottom closing a basal end portion of the storage part, and a lid closing the opening in the distal end of the storage part. The storage part is made of a plastic film. The bottom is deformable between a first state and a second state. The bottom is convex in a direction from the distal end of the storage part to a basal end of the storage part in the first state.

The method for attacking a thin cylindrical element to a mold core is a method for attaching a film-like thin cylindrical element, which is formed in a cylindrical shape having a constant cross-sectional shape, to an outer surface of a mold core in a manner so as to cover the mold core. The method includes pressing the thin cylindrical element onto a tip portion of the mold core; guiding the thin cylindrical element to the base end side of the mold core while ejecting gas into between the mold core and the thin cylindrical element; and attaching the thin cylindrical element to the outer surface of the mold core in a manner so as to cover the mold core.
