'5 Claims. ((51. 206-62).

This invention relates to packaging device for vehicle Windshields.

It is common today to have large vehicle Windshields at the front and' rear of passenger. vehicles and'these Windshields have a compound curvature in many cases which makes them difiicult to package and ship. The present invention contemplates a packaging device especially useful for rear window shields. These rear windows are formed of an extremely hard glass which has a great deal of structural strength. It is important, however, that the edges of this glass be protected against any chipping or abrasion.

The present packaging device contemplates a complete surrounding of the glass in an enclosure which, in itself, has no particular structural strength but which protects the glass from edge damage.

Other objects and features of the invention relating to the various details and structure of the device will be apparent in the following description and claims.

Drawings accompany the invention and the various views thereof may be briefly described as:

Figure 1, a perspective view of the completed package.

Figure 2, a perspective view of a rear window glass ready for packaging.

Figure 3, a view of a one-piece packaging unit.

Figure 4, a sectional view on line 44 of Figure 2.

Figure 5, a sectional view on line 5-5 of Figure 1.

Figure 6, a sectional view on line 66 of Figure 1.

Figure 7, a view of a two-piece packaging shield.

Referring to the drawings:

In Figure 2, a glass is shown provided with small hard formed paper cylindrical units 20, shown in cross section in Figure 4, taped onto the glass by strips 22. The packaging device shown in Figure 3 comprises a single sheet of corrugated paper material or its equivalent which has fold creases or scoring 24 formed in the ends to permit the ends to be folded around, as will later be described. In the top and bottom edges are handle openings 26, at one side, and 27 at the other, the openings 27 having flaps 28 which are not removed. Also at one longitudinal edge are parallel slits which form tabs 30. At the other edge are openings 32 to receive tabs 30. Centrally of the device a crease 34 is provided terminating in a notch 36 at each end, and slits 38 create tabs 40 centrally of the device. Cut outs 42 below tabs 40 serve in co-operation with tabs 40.

When the device is applied to the glass, as shown in Figure 1, the handle of flaps 28 are passed through the handleholes 26 and stapled in place, thus locking this edge of the package. At the bottom of the glass the tabs 40 are folded through openings 42 to be snug with the bottom edge of the glass. Tabs 30, which are longer, are folded through openings 32 around the top edge of the glass, as shown in Figures 1 and 5.

Thus, if the glass is varying in vertical height, the bottom tabs can be folded snug with the bottom edge of the glass, the tab 40 folding at its base. It is preferred itself fto. the particular size of the. glass being wrapped.

gagement with. the sidesof the package,.willtransmit the- 2 load to-a large area.

The ends of the-package are completed by folding the twoendflaps 56- and. 58 in tight association with the ends of theglass on the nearestcrease 24 which adapts End. tab 56 is narrower than tab 58 due to cut-out..36 and a corner cut-out60. The end tabs may then. be stapled so that the glass'will' not shift in the package. The

end tabs

56 and 58 may be folded together or alternately lapped over the ends of the glass. It is preferred that the wider tab 58 be stapled against itself. This alternate folding is shown in Figure 6.

In Figure 7, a slightly modified version of the construction is shown in which the front and back or top and bottom portions are split into separate units. The main panel 70 has a handle opening 72 and top and

bottom fiaps

74 and 76. The ends of this panel are creased at 78. The supplementing panel has a top tab 82 with a handle opening and tab 84 and a bottom tab 86 which registers with the inner cuts forming tabs 76. The narrower ends of panel 80 are also creased at 88.

In assembly, this device would operate in very much the same way as the device shown in Figure 3. The glass is sandwiched between the two panels 70 and 80. The handle tab 84 is then passed through the opening 72 and stapled. First, the tabs 76 would be passed over the bottom edge of the panel 80 to the full extent of their length, and then the longer tabs 74 are passed over the top edge. of the panel 80 to such extent as will accommodate the glass; then the device is taped as previously. The ends are closed and stapled as in the previous modification.

It will thus be seen that there is provided a complete enclosure for the edges of the tempered glass panel which can be shipped now without further packaging.v

The panel itself furnishes adequate strength for the unit and the protective cover prevents edge damage to the panel. The panel is positively spaced from the load bearing edges of the package so that the panels, which are usually shipped on edge, will be cushioned against direct contact with a track floor or other conveyance.

What is claimed is as follows:

1. A protective shipping closure for frangible plates of varying lengths and widths such as vehicle rear windows which comprises a frangible plate of tempered glass, a panel overlying each face of said plate, each panel having projecting edges beyond the plate in all directions, means engaging and clamping said portions of projecting edges together where they overlie each other, tab means and notches on said panels registering with each other wherein a tab on one panel is folded through a notch on, and over the outer face of, the other to effect registration of said panels, and means holding said folded tab means in position wherein said plate is confined always safely within the projecting edges of said panels, said panels forming the complete protective closure in combination with said plate.

2. A closure as defined in claim 1 in which folded tabs and notches on one edge of said panels register transversely of said plate with folded tabs and notches on another parallel edge of said panels, and said means for holding said tabs in position comprises strap-like material encircling the panels at said registering notches.

3. A closure as defined in claim 1 in which one of said panels has end portions narrower than the other, both end portions being'folded over said plate and the wider end being fastened to itself outside said narrower end.

4. A protective shipping device for frangible plates of varying lengths and widths such as vehicle rear windows which comprises a frangible plate of tempered glass, a panel overlying each face of said plate, each panel being longer than the plate to be protected, one of said panels being narrowed at the ends relative to the other whereby said ends are each folded around the plate,

and means fastening each wider end to itself outside the narrower ends, central tabs extending from each side of one of said panels, and flanking tabs on the other of said panels positioned to register with edges of said central tabs, said flanking tabs being folded around and in contact with the outer face of said one panel adjacent the central'tabs to locate said panels relative to each other, and strap means to hold said flanking tabs in position around said one panel, said panels forming the of which project beyond all the boundaries of a plate to be protected, and means to interlock said panels against relative displacement to each other and to the plate which comprise intergaging tabs and notches in edge to edge contact with each other, said tabs being folded over the plate and the outer surface of the adjacent panel at the edges of the panel, and strap means to hold .said tabs in folded position, said panels forming the complete protective closure in combination with said plate.
