Ey W. -f/ Y Paul Wasyluka, St. Louis, tainer Corporation, St. Maryland Application Gctober 5, 1954, Serial No. 460,303 11 Claims. (Cl. 206-46) Mo., assiguor to Gaylord Con- Louis, Mo., a corporation of This invention appertains to packaging for fragile articles, such as deeply curved sheets of glass. More particularly it refers to a container and interior packing therefor of the type made of solid fibreboard, corrugated fibreboard or other suitable material.

Prior to the present time, the great majority of frangible sheets, such as automobile windshields, were relatively flat in shape, or at the most, only slightly curved or bent in configuration. With such sheets it was a comparatively simple matter to package them for shipping by merely completely isolating the sheet from the side walls of the exterior container. Since the sheets were essentially in a single plane, there was little or no tendency for bending or exing when subjected to end-to-end or lengthwise impact. This was due to the fact that the end-to-end impact was readily transmitted through the sheet from one end to the other with little or no tendency to ex or bend the frangible article. With substantially co-planar glass or similar articles, it is possible to provide interior packing which firmly grips the end extremities of the glass in isolated relation from the adjacent portions of the exterior container. An example of a container adapted for fragile, relatively slightly curved sheets lying substantially in a single plane is illustrated in Patent No. 2,665,804, issued to M. C. Koester on January l2, 1954.

With the advent of modified designs for automotive vehicles requiring deeply curved windshields, new packaging problems occurred. The deeply bent glass windshields have substantial portions, usually the ends, which are not only positioned outside the plane of the central portion of the glass sheet, but are sometimes even disposed in substantially normal or even right angular relation to the remaining, central portions. Many attempts have been made to package the deeply curved, fragile sheets employing theretofore known means of maintaining the Sheet within an exterior container, for example, by engaging the end edges of the sheet to prevent movement within the container as in the Koester patent. The resulting breakage soon made it apparent that an entirely new method for packaging the deeply curved sheets must be employed, due to the extreme likelihood of the glass or other fragile material flexing or bending when subjected to end-to-end or lengthwise impact. It is therefore an object of this invention to provide a container having interior packing adapted to support a deeply curved, frangible sheet in completely isolated relation from the sides of the exterior container and in which the end edges of the sheet are generally free to move longitudinally within the container.

A further problem confronting packagers of the relatively new, deeply curved glass sheets was that of providing a means for floatably maintaining the contents within the container and at the same time providing means for gradually and firmly decelerating the movement of the contents against transverse or lateral impact. It is, therefore, another object of this invention to provide a container having a cradle adapted to provide a variable amount of support for the end extremities of the frangible contents, the amount and rmness of support depending upon the magnitude and severity of the transverse or lateral impact.

A still further object is to provide a container having central members to engage the upper and lower central portions of the article to completely isolate these portions from the exterior container walls.

Still another object is to provide a container which has a rigid interior member adapted to tit in slidable engagement against the curved portion of a deeply curved frangible sheet to translate end-to-end impact and movement within the container into lateral and transverse movement.

A still further object is to provide a container of the type described wherein a minimum number of interior pieces are required.

These and other objects will be apparent to those skilled in the art upon a full and complete understanding of the construction and operation of the device.

The invention consists in the parts, arrangements and combinations of parts hereinafter described and claimed. The accompanying drawings from a part of this specification and like numerals and symbols therein appearing refer to like parts wherever they occur.

A particular embodiment of an exterior container or carton A is illustrated in blank form in Fig. 1. While any desired'type of exterior container may be employed, the embodiment illustrated is what is commonly known in the industry as a regular slotted carton having side walls 20. and end -walls 21 connected along corner defining scores 22. A top score' 23 defines the inner margin of foldably connected side top fiaps 24 and end top iiaps 2S. Flap slots 26 positionedy in alignment with adjacent corner defining scores 22 define the end edges of the

top flaps

24 and 25. In a similar manner, a bottom score 27 defines the inner margin of bottom side fiaps 28 and bottom end flaps 29. Flap slots 26 also define the end through section 14-14 of edges of the

bottom flaps

28 and 29. In the embodisupporting pads 31 employed in the embodiment of the invention described. The lar in. outline, however, bevaried if desired. A

pad 31 is essentially rectanguthe configuration thereof may plurality of transverse scores 32 define an inclined panel 33, an inner vertical panel 34,

an outer panel 35, a rear panel 36 and an inner panel 37. The transverse scores 32, in addition, define back and front

article engaging panels

38 and 39 respectively which are separated by a bottom article engaging panel 49. A series of front cushioning panels 41 are also foldably connected along transverse scores 32. The function and relationship of the various panels defined by the transverse scores 32 will be described fully later in the specification.

End cradle members 42 are shown in blank form in Figs. 3 and 4. They are substantially identical in appearance, being complementary duplicates. Each cradle member 42 is provided with a top member 43 which is partially deiined by a top cradle score 44, which extends transversely of the blank 42. In the embodiment illustrated, the distance between the top cradle score 44 and the opposing free side edge of the top member 43 is preferably substantially equal to the interior width of the exterior container A. A similar bottom member 45 is defined in part by a bottom cradle score 46. Similarly, the distance between the bottom cradle score 46 and the opposing free edge of the bottom edge 45 is preferably substantially equal to the interior width of the container A. A middle cradle member 47 is provided intermediate the top and

bottom members

43 and 45 respectively. The middle member 47 is preferably rectangular in outline and substantially narrower than the top and

bottom members

43 and 45, thereby defining overhanging side portions 48 on

members

43 and 45. The middle cradle member 47 is, in the embodiment described, provided with a plurality of middle scores 49 extending` transversely of the middle cradle member 47. In addition, auxiliary scores 59 are positioned in intermediate, spaced, parallel relation between the top and`

bottom cradle scores

44 and 46 and the middle scores 49. The location and number of the

scores

49 and 450 may vary within the limits of the invention, the variation being dependent upon the configuration of the article carried.

Right and left handed duplicate die cnt corner pads 51 are shown in Figs. 5 and 6 and are provided with a, straight side edge 52 and curved edges 53. A spaced parallel pair of corner pad scores 54 define end panels 55 and an intermediate panel 56. Each end panel 55 is provided with an end panel slot 57 extending inwardly ata convenient angle, depending upon the specific curvature of the end portion 64 of the windshield, for example, about 45 to the straight side edge 52 of the pads 51.

As illustrated in Figs. 7 and 8, right and left handed corner pad reinforcements S are provided with inclined end edges 59 and straight inner and outer side edges 60 and 61 respectively. The outer side edges 61 are provided with a pair of spaced corner pad receiving slots 62 spaced apart a distance substantially equal to the dis tance between the corner pad scores 54.

In order to assemble the package for use, it is desirable to erectthe exterior container A. One method is to fold the right handed end Wall 2i, shown lin the blank in Fig. l, upwardly and inwardly about its adjacent corner definingy score 22 into flatwise relation with its adjacent side wall 20. The side wall at the left of the blank is then folded upwardly and inwardly about its adjacent corner dening score 22 into iiatwise contacting relation with the adjacent end wall` and the exposed portion of the adjacent side wall 20. In this position, the sealing ilap 30 will be in iiatwise contacting relation with the free edge margin of the previously folded and positioned end wail 2i. The sealing iiap 30 is then secured to the adjacent end wall 21 by means of stitches 63, glue or other suitable securing means. Thev container A may then be erected so that the side and end

walls

20 and 21 are: positioned in rectangular, tubular relation with respectto each other. Thebottom end flaps 29 are then folded inwardly about the adjacent' portion of the bottom score 2T. into substantially right angular relationship with their adjacent end vwalls 21. Next, the bottom side aps are similarly folded inwardly about the adjacent portions of the bottom score 27 into flatwise relationship with the previously positioned bottom end flaps 29. The bottom side aps may be permanently secured into position by adhesive spread on the bottom face of the bottom end flaps 29, stitches 63 or gummed tape 63', or other securing means may be employed if desired. The exterior container A is now ready to receive the fragile, deeply curved sheet.

The end cradle members are made ready to be inserted into the container by folding the top and

bottom members

43 and 45 respectively backwardly about their adjacent top and bottom cradle scores 44 and 46 into substantially right angular relation with the middle cradle member 47. Next, the scores 49 and the auxiliary scores 50 are broken so as to permit the middle cradle member 47 to assume a gradually curved configuration as shown best in Figs. 9 and l2. The exact configuration of the middle cradle member 47 is unimportant at this point, since as will be apparent from a later description, the cradle member will automatically assume the proper curved outline of the article carried. Each end cradle member is then placed into the previously erected exterior carton A with the bottom member panel 45 in liatwise contacting relation against the previously infolded bottom end ilap 29 as shown, for example, in Fig. l2. in the embodiment illustrated, the overhanging side portions 43 and the bottom member 45 extend inwardly toward the center of the container while the opposing side edge of the bottom member is in abutting, contacting relation with the inner face of the adjacent container end wall. The free end edge of the bottom member 45 and the opposing margin defined by the bottom cradle score 46 are in firm contacting relation with the inner faces of the adjacent side walls 2i). In this manner, the bottom member 45 is firmly maintained in position in the exterior container. To facilitate further assembly of the interior components of the container, the top member 43 of each end cradle member 42 is temporarily folded outside the container walls thereby exposing the interior face of the middle cradle member 47 which generally faces the front wall of the exterior container A.

Next, the central supporting pads 31 are erected by folding the components thereof about the transverse scores 32 to provide a supporting pad as illustrated best in Fig. 13. There are two central supporting pads, one adapted to fit into the bottom portion of the container and another adapted to iit into the top of the container. Both the top and bottom pads are identical except they are complementary to each other, i. e., the bottom pad 31 is adapted to receive the lower edge ofthe contents, while the top pad 31 is adapted to receive the upper edge ofthe contents. The inclined panel 33 is adapted to provide additional strength and rigidity to the inner and outer panels 3S and 37 and to prevent accidental movement of the contents toward the rear of the container. As will be apparent from later portions of the descriptions, thek back and fron-t article engaging panels 38 and 3-9 are folded about their adjacent transverse scores 32 into vertical article receiving relation. A plurality of front cushioning panels 41, vertically disposed and in contacting relation, to the inner face of the adjacent side wall 20 of the container act to prevent accidental movement-of thev contents toward the front of the container.

The bottom central supporting pad 31 is inserted into the container with the front portion thereof defined by the front cushioning panels 41 being positioned adjacent the interior face of the front sidewall Ztl of the container as illustrated in Fig. 9. The end margins of the bottom central supporting pad 31 are dimensioned to extend over the overhanging side portions 48 of each of the end' cradle members 42 so as to lirmly retain them in position within the. exterior container. As illustrated in the embodiment, it is desired that the length of the central supporting pad 31 will be such that the end edges thereof will engage the adjacent side edges of the previously formed middle cradle member 47 thereby preventing accidental, horizontal movement of the bottorn central supporting pad 31. The package is now ready to receive a deeply curved, frangible article such as a glass windshield B or the like. The curved windshield B is inserted into the container so that the central portion of its lower front and back surfaces are received between the back and front

article engaging panels

38 and 39. The curved windshield will be further lowered into the container until the central portion of its lower edge is in contact with the bottom article engaging panel 40. In the particular embodiment of the invention illustrated, the central portion of the windshield is relatively straight so that the distance between the back and front

article engaging panels

38 and 39 is substantially equal to the thickness of the windshield B. However, in modified, curved, frangible sheets wherein the central portions are more deeply curved, it may be necessary to vary the width between the back and front

article engaging panels

38 and 39 to accommodate the central portion of the article. As illustrated in Fig. 13, the central portion of the bottom edge of the windshield B is maintained in spaced relation from the bottom of the container.

The particular embodiment of the invention illustrated is designed for a deeply curved windshield having end portions 64 terminating in substantially right angular relation to the center portion of the windshield, the end portions decreasing gradually in width to provide a curved, tapering configuration as illustrated in Fig. 12. The lower edge 65 of the windshield will be received in contacting relation with the adjacent lower scored portion of the middle cradle member 47. At this particular stage of the loading of the container, the middle cradle member 47 will provide little or no support for the end portions 64 of the curved windshield B.

The corner retaining members 51 are erected by folding the end panels 55 upwardly about the corner pad scores 54 into substantially right angular relation with the intermediate panel 56 In this position, the end panel slots 57 will be disposed in spaced parallel relation with each other. The corner pad reinforcement 58 is then inserted into the previously erected die cut corner pad 51 by guiding the corner pad slots 62 into the end panel slots 57. The erected corner retaining member will appear as best illustrated in Fig. 9. The straight side edge 52 will be, in the embodiment described, folded to form substantially a right angle with respect to the intermediate panel 56. The curved edges 53, now disposed in spaced parallel relation to each other, are preferably the precise curvature of the adjacent curved portions of the curved windshield B when the corner member is inserted in place. The corner member is inserted into the container so that the lower inclined end edge of the corner pad reinforcement 58 is in normal, contacting, abutting relationship with the lower portion of the middle cradle member 47. The curved edges 53 are in substantially normal contacting, abutting relation with the curved end portions of the windshield B and the intermediate panel 56 and the adjacent straight side edges 52 are in firm contacting relation with the adjacent interior faces of the corner of the exterior container A. The corner member is rigidly and firmly disposed within the container, and in firm contacting relation against the curved windshield member.

If desired, a reinforcing center rib 66 comprising a pair of foldably connected side fiap members 67 may be placed onto the inner panel 37 of the bottom central supporting pad 31 as best shown in Fig. 14. The purpose of the center rib 66 is to provide a reinforcing support for the upper central supporting pad 31, therefore, it is desirable that the width of the side iiap members 67 be sufficient to engage the inner panel 37 of the upper, central supporting pad 31 when placed into the container, as later described, to maintain it in substantially horizontal, parallel relation with respect .to the lower central supporting pad 31, thereby providing an additional stacking reinforcement.

The top central supporting pad 31 is now placed within the container so that the bottom margins of the inner panel 37 are in contacting, abutting relation with the top edges of the side flap members 67. In this position, the upper side marginal surfaces of the central por tion of the windshield B are firmly received between the back and front

article engaging panels

38 and 39 of the top central supporting pad 31. Also, the center portion of the top edge of the windshield is in contacting relation with the inner face of the top article engaging panel 40. In a manner similar to the bottom central supporting pad, the outermost front cushioning panel 41 of the upper central supporting pad 31 is in firm contacting relation against the adjacent inner face of the front side wall 20 and the rear panel 36 is in similar firm contacting relation against the adjacent face of the rear side wall 20.

The top member panel 43 of each of the end cradle members is then lifted into horizontal position across the top of the container as illustrated in Fig. l2. The positioning of the top member is accomplished by positioning the edge defined by the top cradle score 44 against the upper inner face of the container front side wall 20. As the top member 43 is positioned, the slack is taken out of the middle cradle member 47 so that the end portions 64 of the windshield B are firmly supported throughout the major portion of their upper edges 68 and lower edges 65. In effect, the curved middle cradle member 47 acts to hold the curved windshield B toward the front of the container against the die cut corner members. The middle scores 49 and the auxiliary scores 50 permit the middle cradle member 47 to bend to conform with the shape of the end portions 64 of the windshield and thereby firmly embrace the edges 65 modified shaped end portions, it may be desirable to vary the positioning of the

scores

49 and 50 so as to permit the middle cradle member 47 to more readily conform to the modified shape of the end portions.

As the top member panel 43 is placed horizontally across the top of the container, the overhanging side portions 48 thereof will come to rest in iiatwise contacting relation against the upper face of the adjacent portions of the outer panel 35 of the upper central supporting pad 31. In this manner, the top member 43 is prevented from becoming displaced into the container during shipment. To complete the packing of the container, the end top iiaps 25 are folded inwardly into fiatwise relation against the top member 43 and in a similar manner, the side top flaps 24 are folded inwardly into horizontal, contacting relation against the end top flaps and secured thereto by glue, adhesive, staples 63 or other desirable securing means. In addition, tape 63 may be applied if desired.

The package thus provided embodies entirely new concepts for protecting deeply curved, frangible sheets during transit. As mentioned previously in the speciiication, one of the primary types of impact which commonly causes fracture of the curved sheets or windshields is longitudinal or end-to-end shock or movement. With the present invention, when longitudinal shock or impact occurs, the windshield tends to slide within the container in a lengthwise direction. The lengthwise movement will be arrested by the corner members which are firmly disposed between opposed end corners of the exterior container A and the curved surface of the windshield member. Due to the rigidity of the corner member and the cooperating curved edges 53 thereof, any longitudinal or end-to-end movement of the contents is gently translated into transverse or lateral movement at the end of the container. The lateral movement of the and 68. Of course, with lading havingy curved end portion 64 of the windshield is gently arrested by the curved middle cradle member 47 which, due to its iiexible nature, engages substantially the entire edge portions of the ends 64. Packages employing this invention gently but firmly cushion the deeply curved frangible sheet against longitudinal movement without permitting the curved end portions 64 to l'lex longitudinally inwardly which, in the majority of instances with curved glass sheets of the type described, causes immediate fracture and failure. lt will be noted that in reality the edges 65 and 6,8 of the end portion 64 are entirely free to move longitudinally within the container since the middle cradle member which supports them, restrains movement within a lateral direction only.

The package also effectively cushions the contents against fracture and failure from vertical and lateral shock and impact. That is, the curved middle cradle members equally gently restrain movement when the exterior container is subjected to vertical and lateral impact.

Various modifications of the embodiment described may be employed to modify the package for particular articles and to suit various types of shipping conditions. For example, the central supporting pad may be varied by omitting one or more of the front cushioning panels toprovide a more springable padding effect for the forward portion of the supporting pad.

The particular embodiment described and the variations thereof are intended to be illustrative and not restricted and it is to be understood that the invention herein is susceptible of further modified forms and all such modifications which are similar or equivalent thereto come equally within the claims next appearing.
