Baby's bath |
摘要 |
This invention is concerned with inflatable plastic baby baths similar in shape to a rubber tire inner tube having an impervious web across the ring. The web is preferably midway between the top and the bottom of the inflatable tube or annulus, and by inflating the article while hot during manufacture a smooth and wrinkle-free appearance can be produced. Such a plastic bath can be made virtually immovable on a smooth surface by expelling air from under the web and causing a partial vacuum. The diameter of the inflated tube is sufficiently great relative to the width of the web to prevent the web touching the supporting surface in normal use.
