Abstract
A covered balloon for use as a toy or in a display, which includes a cover formed of a plastic film and a rubber balloon inside the cover. More specifically, the cover is formed of two superposed sheets of substantially gas impervious plastic film whose peripheral edges are welded to form a seam. In a one embodiment, the cover and the rubber balloon each have a nozzle and the rubber balloon is inflated so as to fill the entire space within the cover and eliminate any wrinkles in the cover and adhere to an interior surface of said cover with the nozzle of the rubber balloon protruding from the cover through the nozzle of the cover. A welding flap formed along the seam when the cover is formed by welding together the plastic sheets, may be substantially reduced in size by cutting the flap along the seam. The cover may be formed of a transparent film such as a film of ethylene-vinyl alcohol copolymers so that the rubber balloon inside is visible. According to another embodiment, the rubber balloon fills only a portion of the space within the cover, the remainder being inflated with a gas.
