Claim 5

The packaging device of claim 3 wherein said T-shaped tab members include fold lines to facilitate inserting said tab members into said corresponding slots.

Claim 6

The packaging device of claim 4 wherein said second panel includes a fold line dividing the same into said upper portion and the portion thereof which is fastened to said first panel.

Claim 7

The packaging device of claim 4 wherein said first and second panels are flat and wherein said packaging device is adapted for packaging planar articles.

Claim 8

The packaging device of claim 6 including a planar, sheet-like glass article packaged therein.

Claim 9

The packaging device of claim 4 wherein said first and second panels are curvilinear and wherein said packaging device is adapted for packaging curvilinear articles.

Claim 10

The packaging device of claim 8 including a curvilinear sheet-like glass article packaged therein.

Claim 11

A packaging device for a fragile plate-like article, which comprises: a generally rectangular body having a first longitudinal fold line dividing said body into first and second panels, and a second longitudinal fold line dividing said second panel into a lower portion and an upper portion, said first panel having substantially the same dimensions as the lower portion of said second panel, said body being folded along said first fold line such that said first panel and said lower portion of said second panel are disposed in face-to-face relationship with the longitudinally disposed edge of said first panel being adjacent said second fold line; means fastening said first and second panels along their side marginal edges such that the space bEtween the respective panels defines an envelope-like receptacle; said first panel having at least one foldable T-shaped tab member formed therefrom and attached thereto adjacent said longitudinal edge thereof; said upper portion of said second panel including slot means for receiving said T-shaped tab members when said T-shaped tab members are folded in the direction away from said receptacle and when said upper portion of said second panel is folded over said longitudinally disposed edge of said first panel and downwardly between the T-shaped tab members and the surface of said first panel which faces away from said receptacle.

Claim 12

A packaging device for a fragile plate-like article, which comprises: a generally rectangular body having a first longitudinal fold line dividing said body into first and second panels, and a second longitudinal fold line dividing said second panel into a lower portion and an upper portion, said first panel having substantially the same dimensions as the lower portion of said second panel, said body being folded along said first fold line such that said first panel and said lower portion of said second panel are disposed in face-to-face relationship with the longitudinally disposed edge of said first panel being adjacent said second fold line; means fastening said first and second panels along their side marginal edges such that the space bEtween the respective panels defines an envelope-like receptacle; said first panel having at least one foldable T-shaped tab member formed therefrom and attached thereto adjacent said longitudinal edge thereof; said upper portion of said second panel including slot means for receiving said T-shaped tab members when said T-shaped tab members are folded in the direction away from said receptacle and when said upper portion of said second panel is folded over said longitudinally disposed edge of said first panel and downwardly between the T-shaped tab members and the surface of said first panel which faces away from said receptacle.

Claim 13

The packaging device of claim 10 wherein said first and second panels are stitched along their side marginal edges.

Claim 14

The packaging device of claim 11, wherein said T-shaped tab members include fold lines to facilitate inserting the same into said corresponding slots.

Claim 15

The packaging device of claim 12 including a sheet-like glass article packaged therein.

Claim 16

A packaging device for sheets of frangible material such as vehicle windshields and the like, which comprises: a frangible sheet having forward and rearward surfaces; a first generally rectangular panel member overlying said forward surface of said sheet and having dimensions greater than said sheet, said first panel member having at least one foldable T-shaped tab member formed therein and attached thereto adjacent the top edge thereof; a second generally rectangular panel member overlying said rearward surface of said sheet and having side and bottom marginal edges which coincide substantially with the corresponding side and bottom marginal edges of said first panel member, the vertical dimension of said second panel member being greater than the vertical dimension of said first panel member such that said second panel member includes a generally rectangular upper flap portion which extends above the top edge of said first panel; said upper flap portion being foldable in the forward direction over said first panel and including slots corresponding to said T-shaped members and adapted to lockingly receive said T-shaped members when said T-shaped members are folded in the forward direction and the flap portion is folded over the top edge of said first panel and between said T-shaped members and the forward surface of said first panel member.

Claim 17

A packaging device for sheets of frangible material such as vehicle windshields and the like, which comprises: a frangible sheet having forward and rearward surfaces; a first generally rectangular panel member overlying said forward surface of said sheet and having dimensions greater than said sheet, said first panel member having at least one foldable T-shaped tab member formed therein and attached thereto adjacent the top edge thereof; a second generally rectangular panel member overlying said rearward surface of said sheet and having side and bottom marginal edges which coincide substantially with the corresponding side and bottom marginal edges of said first panel member, the vertical dimension of said second panel member being greater than the vertical dimension of said first panel member such that said second panel member includes a generally rectangular upper flap portion which extends above the top edge of said first panel; said upper flap portion being foldable in the forward direction over said first panel and including slots corresponding to said T-shaped members and adapted to lockingly receive said T-shaped members when said T-shaped members are folded in the forward direction and the flap portion is folded over the top edge of said first panel and between said T-shaped members and the forward surface of said first panel member.

Claim 18
