发明名称 Disposable cap with straps
摘要 A disposable cap is formed by sealing together two sheets of thermoplastic film in such a manner as to form an enclosure having an access opening with respect thereto. Adjacent the access opening in one of the sheets of film is cut a T-shaped arrangement of slits which form two straps or ties in the resulting product. These straps or ties are located adjacent the opening and are attended to adapt the construction to the various head sizes of various users. The excess film material is trimmed off. A relatively large seal is effected adjacent the roots of the ties or straps in order to provide an anchorage for the same.
