3 Claims. (Cl. 206-62) This invention appertains to the packaging of fragile articles, and more particularly to a novel carton for shipping curved Windshields and like glass of the so-called panoramic or wrap-around type, and is an advancement in the art over the prior Patent No. 2,812,855, issued November 12, 1957, to Lloyd D. Van Antwerpen and assigned to the Vanant Company, Inc., Milwaukee, Wisconsin.

Much difficulty has been experienced in the packaging and shipping of curved automobile glass. Due to the cost of the glass, great care must be taken in the adequate protection thereof against rough handling during the shipping thereof. Owing to the curvature of the glass, cartons of great width as well as length had to be employed. Not only were the cartons costly, but the cartons of necessity occupied great space in shipping and storing.

It is, therefore, one of the primary objects of the invention, to not only provide a carton which will follow the contour of the glass, but one which will adequately protect the glass and one which will permit eifective nesting of a plurality of cartons for the saving of space during shipping and storing.

Another salient object of the invention is to provide a contour carton for curved automobile glass embodying a straight body portion and laterally extending oppositely diverging wings, the construction being such that the body of the curved glass is received in the body of the carton and the wings of the glass are received and effec tively housed within the wings of the carton.

A further object of the invention is to provide novel means for constructing the carton, whereby the inner straight side wall of the body of the carton will be of a length at least equal to or greater than the length of the outer side wall of the body of the carton, whereby one carton will readily and sungly fit into another carton to permit the eifective nesting of a plurality of cartons.

A still further object of the invention is the provision of a novel arrangement of flaps on the wings of the carton so as to permit the effective bracing thereof, at least one of said flaps extending into the body of the carton from the wings to give a desired additional support.

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 perspective view of the improved carton showing one embodiment of the invention;

Figure 2 is a view similar to Figure 1 with the upper end of the carton open ready to receive a curved windshield or like glass;

Figure 3 is a perspective view of one end of the carton showing certain of the closure flaps of the wings in their folded position;

Figure 4 is a top plan view showing a plurality of the cartons in their nested position for shipping or storing;

Figure 5 is a top plan view of one of the cartons, parts of the figure being shown broken away and. in section to illustrate the position of a packed curved windshield or the like therein, the part of the figure in section being taken on the line 5-5 of Figure 6, looking in the direction of the arrows, and

Figure 6 is an inner side elevational view of the carton with a curved glass packed therein, parts of the view being shown broken away and in section to illustrate the means of suspending the curved windshield. or like glass in the carton.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter C generally indi cates the improved carton for the shipping and storing of curved automobile glass, such as a windshield W. The curved glass, such as the windshield W forms no part of the present invention but the same is of the so-called panoramic or wrap-around type, and hence includes an arcuate body portion 10 and laterally extending curved wings 11. With the trend of using more glass in automobiles, the wings of the automobile glass both for the Windshields and rear windows increase in length and curvature.

In order to adequately protect and suspend the glass W in the carton C, the peripheral edge of the glass is received within a packaging strip S, which can be of the type shown in the Vanant Patent No. 2,776,745, issued January 8, 1957, to Lloyd D. Van Antwerpen. It is to be noted that the width of the strip S is equal to the width of the carton so that lateral shifting of the strip S and the windshield in the carton will be eliminated.

Now referring to the carton C the same includes a straight main body portion 12 and laterally extending diverging wings 13 and 14. The wings 13 and 14 are of identical shape and construction.

The body portion 12 of the carton includes straight inner and outer side walls 15 and 16. The inner straight side wall 15 has a length at least equal to the outer straight side wall 16 and preferably of a length slightly greater than the outer side wall 16, for a purpose, which will later appear. These side walls carry closure flaps 17 and 18 and when the box is assembled for shipping the flap 17 completely overlies the flap 18 and is firmly secured thereto by suitable adhesive. The lower edges of the inner and outer side walls 15 and 16' carry similar bottom closure flaps 19 and 20 and these flaps are initially sealed together to form the bottom wall of the box.

Each of the wings 13 and 14 includes inner and outer side walls 21 and 22 which are formed on the transverse edges of the inner and outer walls 15 and 16. The outer side walls 22 of the wings have formed thereon inwardly directed end walls 23. The inner side Walls 21 have formed thereon sealing flanges 24 which extend over the end walls and are firmly secured thereto by a desired type of adhesive.

The tops and bottoms of the wings 13 and 14 are closed by similar closure flaps and in the forming of the box, the closure flaps at the bottoms of the wings are initially sealed together at the same time as the sealing of the bottom flaps 19 and 20 of the body portion 12 of the carton. This permits the setting up of the box for the reception of the windshield or like glass W and its supporting cushioning packaging strip S. In view of the fact that the closure flaps for the Wings both at the tops and bottoms of the wings are identical, the closure flaps for the tops of the wings are set forth in detail only. The end Walls 23 at their top and bottom carry and have formed thereon inwardly bendable closure flaps 25, and these flaps, as best shown in Figure 6, extend over the are firmly secured together by a suitable adhesive.

swung over the flaps 27 and sealed thereto. the main body flap 18 is swung downover the glass and assumes somewhat of a U-shape in plan.

when the flaps 25 are in their folded lowered-position. The; provision of the wings 26 forms meansfor bracing the walls 21 against collapsing. 'T he outer side walls 22 =of the wings have formed on their upper and lower edges 'foldable flaps 27 and theseflaps are adapted to be folded down over the flaps 25. The flaps 27 form an important -'-feature of the invention and the same are of such a size and shape as to extend well into the body portion 12 of the cartonwhen'the flaps-are in their lower closed position, and these flaps also extend over and engage the packaging cushion strip S. By extending these flaps into the body portion of the carton, the sameserve as an ef- -fective bracemeans for the wings and the body portion of the carton. The inner edges of the flaps 27 have formed thereon depending right angularly extending wings 28 which are adatped to be inserted between the wings 26 of the flaps 25 and the inner side walls 21 of the wings.

The inner edges of the flaps 27 have also formed thereon depending tabs 29, which extend at an angle to the -wings 28 and these tabs engage the opposite ends of the inner side wall 15 when said flaps 27 are in their lowered position. Formed on the upper and lower edges of the inner side walls 21 are bendable sealing flaps 30 and these flaps are adapted to be folded over the outer faces of the flaps 27 and it is to be understood that all of the flaps The flaps "30 are ofa trapezoidal shape and their outer edges have formed thereon depending right angularly extending sealing flanges 31 which extend over the outer surfaces of the end walls 23 and these flanges are firmly sealed to the end walls 23 by the adhesive.

Considering that the carton is in its set up condition,

with all of the bottom flaps closed and sealed togetherthe automobile glass is then wrapped with the cushioning and protecting strip S and the glass'is then inserted in the carton through the upper end thereof. Due to the tapering ofthe wings of the glass,-it is desirable to use chucking blocks 32 which can be formed from suitable corrugated board and these blocks engage the upper and 'lower edges of the wings and the blocks engage the end walls of the carton and the top and bottom walls of the carton. With the windshield in place, the flaps 25 are first bent down over the wings of the glass and the cushioning blocks 32, as heretofore stated. After this, the 'fiaps27 are swung down and sealed to the flaps 25. With the flaps 27 in their closed position the flaps 30 are then After this the flaps 27 and the flap 18 are sealed to the outer surface of the flaps 27 by adhesive. Again, at this point,

it is to be noted that the flaps 27 extend into the body portion of the carton and form means for bracing and supporting the body flap 18. With the body flap .18

swung down and sealed at the flaps 27, then the outer 'flap 17-is' swung down-and sealed to the flap 18.

This forms a rugged carton and the windshield or other curved glass is eflectively carried and supported thereby.

As the wings 13 and 14 diverge outwardly, the carton By referring particularly to Figure 5, it can be seen that the inner straight side-wall 15 is of a greater length than the outer side wall 16, and this is brought about by making the outer side walls 22 of the wings of a greater length than the inner side walls 21 of the \m'ngs. With the carton of theshape asset forth above, the samecan be readily .of the inner wall 15 a plurality of the cartons Cean be nested in close compact order, as best shown in Fig. 4. As the outer wall 16 is shorter than the inner wall 15, the same will readily fit into an adjacent carton to bring about the snug intimate nesting. Due to this snug intimate nesting one carton protects the other during shipping and storing, and the likelihood of damage of the glass is lessened.

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

1. A carton for the shipping and storing of curved automobile glass of the type embodying a central portion and curved back diverging terminals, comprising a substantially straight body portion including inner and outer side walls and top and bottom walls including inner and outer overlapping flaps formed on the upper and lower edges of the side walls, and laterally extending diverging wings formed on the body portion of the carton, each of said Wings including inner and outer walls formed on the inner and outer side walls of the body portion of the carton, one side wall of the wings having formed thereon bent back end walls, means connecting the other side walls of the wings to the end walls, end sealing flaps formed on the upper and lower edges of the end walls adapted to be bent inwardly at right angles to said end walls, inwardly bendable flaps formed on the upper and lower edges of the outer side walls of the wings for engagement with the end Wall flaps, said end wall flaps having depending wings engaging the inner surfaces of the inner walls of the wings, said outer side wall flaps extending into the body portion of the carton and under the top and bottom wall flaps thereof, and side wall .sealing'flaps formed on the upper and lower edges of the inner side walls of the wings folda-ble over the flaps of the outer wing side Walls, and depending sealing flanges .carried by the last mentioned flaps for sealing connection with the outer surfaces of the end walls.

2. A carton as defined in claim 1 and said flaps carried by the outer wing side walls having depending flanges engaging the inner faces of the inner side walls of the wings, and a depending tab formed on those portions of the outer side wall flaps extending into the body of the carton engaging the innerside wall of the body of the and curved back diverging terminals, comprising a straight body portion and laterally extending diverging wings defining a carton of a substantially U-shape in plan whereby one carton can be nested within the U of an adjacent carton, each wing including inner and outer side walls, top and bottom walls,-and a flat terminal end wall, the body portion of the carton including inner and outer side walls and top and bottom walls, the inner wall of the body portion being of a greater length than the outer wall of the body portion so that one carton will intimately fit within the .U of an adjacent carton with the outer wall of one carton in substantial engagement with the inner wall of an adjacent carton with the end walls .of the wings disposed in a continuous straight line at right angles to the-inner and outer walls of the body.
