Abstract
A method of simultaneously vacuum forming a plastic article and integrally joining a device thereto is disclosed wherein a lock defining surface is formed on an anchoring end of the device, a heat activated adhesive is applied to the lock defining surface, and air is drawn through vacuum holes in the mold surface that defines the shape of the article and is also drawn through vacuum holes in the lock defining surface to draw a heated sheet of thermoplastic material onto the mold surface and also into interlocking relationship with the lock defining surface to form the article and to mechanically interlock and adhere the device to the formed article.
