Balloon

A toy balloon comprising two plastic films that are stacked and sealed at a peripheral edge,

• the toy balloon including a first part, a second part, and a bending part that is situated between the first part and the second part,
• the bending part including a gas passage through which an interior of the first part and an interior of the second part communicate with each other, and a bending sealed part that is formed by sealing the two plastic films situated opposite to each other in an inward area relative to the peripheral edge, and
• an outer edge of the bending sealed part extending beyond the bending part so as to be situated within the first part and the second part, an entire inner surface of the outer edge being sealed,
• the bending part bending due to tension applied to the bending sealed part by filling the toy balloon with a gas and inflating the toy balloon so that the second part is spontaneously turned relative to the first part and a bent state of the toy balloon is maintained.

• the bending part bending due to tension applied to the bending sealed part by filling the toy balloon with a gas and inflating the toy balloon so that the second part is turned at approximately a right angle relative to the first part and a bent state of the toy balloon is maintained.
