发明名称 Easily feedable envelope construction
摘要 An envelope construction including a pair of superimposed sheets 10, 12 having aligned opposed side edges 14, 16, a third edge 18 of one of the sheets 10 extending between the side edges 14, 16 being enlarged in comparison to the third edge 20 of the other sheet 12 and carrying an adhesive 24 to define a sealable flap 22 for the envelope. A U-shaped glue pattern 28 secures the sheets 10 and 12 together and the bight 32 of the U-shaped pattern is spaced from the third edges 18 and 20 as well as from a fourth edge 34 to define an envelope pocket as well as an envelope extension 36 between the bight 32 and the fourth edge 34. The extension 36 aids in the prevention of hang-up when the envelope is being fed, bottom first, into a stack of envelopes.
