Filed Nov. 7, 1955', Ser. No. 545,326

1 Claim. (Cl..206,--62) This invention appertains. to shipping cartons for the curved rear windows and Windshields of automobiles of the so-called Panoramic or wrap-around type.

As brought out in my co-pending applications Serial Numbers 411,991 and 515,394, filed respectively on May 8, 1954, and June 14', 1955, and now Patent Nos. 2,771,091 and 2,812,855, much difliculty is experienced in the proper packaging of the curved rear windows and Windshields of automobiles, so as to prevent breakage thereof during shipping and handling.

One of the primary objects of my present invention is the provision of novel means forming a. direct part of the carton for encircling the glass as the same is placed in the carton to provide an effective protection for the central part of the glass and,,for preventing lateral shifting of the glass in the, carton. and thus prevent undue strains on the curved terminals. of the glass.

Another salient, object of, my invention is to provide means carried by the body portion of the carton for encircling the central portion of the glass being shipped and for snugly engaging the longitudinal edges of the packaging strip placed about the edge of the glass, whereby the strip will be held in proper position at all times relative to the glass irrespective of the position of the carton during handling and shipping.

A further important object of my invention is the provision of portions cut out from the top and bottom of the sealing flaps of the carton for interconnection when said portions are folded about the windshield with the portions disposed an exact distance from one of the side walls of the carton, so that the portions in conjunction with the side wall will effectively hold the glass in place and the packaging strip extending about the glass.

With these and other objects in "view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described and claimed and illustrated in the accompanying drawings, in which drawings,

Figure 1 is a top plan View of my improved carton with the top flaps in their open position to expose to view the curved glass with the packaging strip thereabout and the inwardly folded wings encircling the central portion of the glass, parts of the top flaps being shown broken away;

Figure 2 is a fragmentary longitudinal sectional view through the carton taken on the line 22 of Figure 1, looking in the direction of the arrows, the view showing the wings encircling the glass, a part of one of the wings being shown broken away;

Figure 3 is a fragmentary transverse sectional view through the carton taken on the line 33 of Figure 2, looking in the direction of the arrows;

Figure 4 is a perspective view of the carton showing the same in its open condition;

Figure 5 is a perspective View of the carton showing the same in its partially opened position;

Figure 6 is a perspective view of the carton showing the same in its completely closed, sealed position, and

Figure 7 is a plan view of the blank from which the carton can be made.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter C generally indicates my improved carton and B (see Fig. 7) a blank from which the carton can be formed.

The carton C includes

like side walls

10 and 11 connected by an end wall 12. As shown in Figure 7 the blank is scored transversely, as at 13 and 14, to define the end wall 12. One transverse edge of the side wall 10 has formed thereon the opposite end wall 15 and this end wall is defined by a transverse score line 16-.

Referring more particularly to the blank B it can be seen that the blank is folded on the

lines

13 and 14 and then on the line 16 and this will provide the body portion of the carton of an oblong shape. At this time, the free edge of the end wall 15 can be secured to the free edge of the side wall 11 by heavy adhesive tape. Formed on the longitudinal edges of the side wall 10 and defined by longitudinal score lines 17 are inner top and

bottom closure flaps

18 and 19. These

flaps

18 and 19 are treated in a particular fashion, as will be later brought out so as to give my desired means for protecting the windshield. Obviously, these

flaps

18 and 19 are folded at right angles on the score lines 17 to the side wall 119 to form the desired inner top and bottom flaps. Formed on the longitudinal edges of the side wall 11 are top and

bottom closure flaps

29 and 21. It can be seen that the score lines 17 are continued the entire length of the blank B and hence the

outer flaps

20 and 21 are also bent at right angles to their side wall 11, on the score lines 17. The outer transverse edges of the end Wall 12 have formed thereon top and bottom

end closure flaps

22 and 23, and these flaps are also folded at right angles on the score lines 17. Formed on the transverse edges of the end wall 15 are top and

bottom end flaps

24 and 25 and these end flaps are also folded at right angles to the end Wall 15 on the longitudinal score lines 17. The top and

bottom end flaps

22, 23, 24 and 25 are also defined by transversely extending slits 26 which extend from the longitudinal edges of the blank B to the score lines 17 and these slits 26 separate the end flaps from the top and bottom flaps '18, 19, 20 and 21.

Now referring more particularly to the present in vention, the inner top and

bottom side flaps

18 and 19 are provided with transverse slits 27, and these slits 27 also extend from the longitudinal edges of the blank to the score lines 17 and these slits 27 define therebetween foldable top and

bottom wings

28 and 29. These

wings

28 and 29 are located centrally of the carton when the blank is folded into proper form, as will now appear. It is to be noted that the

wings

28 and 29 are scored on longitudinally extending lines '30 in close but spaced parallel relation to the score lines 17 and this will now be referred to. The

wings

28 and 29 are folded, in setting up the carton from the blank B, first at right angles to the wall 10 on the score lines 17, after which the wings are again folded at right angles on the score line 30 and this defines a spacer wall 31. As previously stated, the blank B is folded on the

score lines

13, 14 and 16 so as to bring the

side walls

10 and 1 1 in spaced parallel relation to one another and the

end walls

14 and 15 in spaced parallel relation to one another, and after which side wall flap 21 is folded over and secured in place. This completes the bottom wall of the carton and the curved rear window W or windshield, as the case may be, is placed in the carton with a packaging strip 32 placed around the edges thereof. This packaging strip can be of the type shown in my pending applications and this strip forms no part of the present invention. With the windshield W in place, as best shown in Figures 1, 2 and 3, the

wings

28 and 29 are folded inwardly toward one another around the windshield and are secured togeth r in any desired way, such as by an adhesive or by wire staples. The

end top flaps

22 and 24 are now folded down over the windshield and rest upon the upper spacer wall 31 of the Wing 28 and this spacer wall forms an eflicient support for these end flaps. The remaining portions of the inner side flaps 13 are now folded down over the

end flaps

22 and 24 and when this is accomplished, the outer side flap 29 is folded down and sealed in place, as best shown in Figure 6.

Now referring back to Figures 1, 2 and 3 the spacer walls 31 of the

wings

23 and 29 are of an exact width so that the packaging strip 32 will be confined between the

wings

28 and 29 and the side wall and thus the packaging strip throughout a good portion of its length will be held in place against lateral shifting movement and consequently the windshield or rear window W will also be held in place against lateral shifting movement. Not only do the

wings

28 and 29 form means for supporting the

end flaps

22, 23, 24 and 25, but they also form means for holding the packaging strip 32 in place and a general protection for the central part of the windshield. As the glass is held against lateral movement, stress is also prevented on the end terminals of the glass which would be caused by shifting of the glass in the carton.

From the foregoing description, it can be seen that I have provided a novel and efficient means for packaging and preventing breakage of curved automobile glass and that the protecting means is formed from a direct part of the carton, thereby eliminating the expense of fabrieating extraneous protecting members.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

A package for shipping curved glass of the panoramic windshield type comprising a carton, a curved windshield in the carton including a main curved body portion and curved back terminals, the carton including side, end, top and bottom walls, a part of the body portion of the windshield lying adjacent to and substantially parallel with one side wall, said top and bottom walls each including inner and outer foldable overlapping side flaps, said inner side flaps having spaced transversely extending slits intermediate their ends and centrally disposed folding wings defined by the slits bent at right angles to the major portion of the inner side flaps and parallel to the mentioned side wall and over the part of the body portion of the glass .lying adjacent to the mentioned side wall to confine the body portion of the glass between the mentioned side Wall and the wings, and said foldable wings having top and bottom spacer walls uniting the same with the mentioned side wall whereby to space the major portions of the wings an exact distance from said side wall.
