Abstract
An open-end cushioned eyeglass case and method of manufacture wherein the case comprises an outer cover of heat-sealable material and a protective inner cushioning layer, the inner layer having a width and length which are each smaller than the width and length, respectively, of the outer cover. The cover and cushioning layer are assembled in overlying relationship with their top edges flush and are sealed together along those edges. The composite sheet is then folded along its longitudinal axis so that the opposed inner peripheral side and bottom edges of the outer cover are in direct contact and these edges are heat sealed together.
Claims9
An open-end cushioned eyeglass case comprising an outer cover of heat-sealable polyvinyl chloride and an eyeglass protecting inner cushioning layer having a width and length which are each smaller than the width and length, respectively, of the outer cover, said cover and said cushioning layer being assembled in overlying relationship with the longitudinal axes thereof being in at least substantial alignment with each other, and at least the upper edge of the cushioning layer being sealed to the inner surface of the cover in proximity to the upper edge thereof forming a composite sheet assembly, said assembly being folded over upon itself along the at least substantially aligned longitudinal axes such that the opposed inner peripheral side edges of the heat sealable polyvinyl chloride outer cover are in direct contact with each other and the folded over inner peripheral bottom edge of the outer cover is also in direct contact, said opposed inner contacting peripheral side edges and contacting bottom edge being electronically heat sealed and form a fused side edge opposite the folded over side edge and a fused bottom edge opposite the upper edge which defines the open end of said eyeglass case, and wherein the cushioning layer does not interfere with the electronically heat sealed and fused bottom and side edges.
