Abstract
ABSTRACT OF THE DISCLOSURE
An accordian fold molded packaging tray is disclosed having article engaging surfaces thereon which change orientation relative to articles stored in the tray such that when articles are placed in the tray such surfaces help to channel the stored articles into position within the tray and then the surfaces are rotated into engagement or proximity to such stored articles to hold the articles during subsequent shipment and storage. This change in orientation of the article engaging surfaces is accomplished by reduction of the overall dimension of the tray which causes the article engaging surfaces to rotate about fold lines formed in the tray.

ACCORDIAI~ FOLD PACKAGING TRAY
SUMMARY OF THE INVENTI0~3 .
The inv~ntion pr~vides an inexpensive molded packa~ing tray for snugly holding bottles or other stored articles. The overall dimensiGn of the tray can be changed by bending along fold lines formed in the tray to acilitate placement of articles in the tray and subsequent safe shipment of such articles. The tray is preferably molded in a configuration wherein the overall dimension of the tray is at its maxim~m, or expanded position, which results in ease of molding and insertion of stored articles. Thereafter ~he dimension of the tray is reduced causing portions of the tray to engage and securely hold the ar~icles stored in the tray in place.

DETAILED DESCRIPTI01~
FIGS. 1-6 illustrate a tray 10 in accordance with one embodiment of this invention. As indicated therein tr y 10 includes a bottom or base 12 and multiple article engaging areas 14 extending from the base 12 to an upper surface 16.
As best illustrated in FIGS. 1 and 2, the tray 10 as molded, for example from molded pulp, contains parallel fold lines 1~, 20 in base 12 and 22, 24 in ~he upper surface 16. These fold lines 18, 20, 22 and 24 are formed in the molding process, for example, by reducing the thickness of the tray 10 along these lines. This reduction of thickness can be accomplished by standard molding techniques well-~nown to those skilled in the art.
The tray 10 as molded is best illustra~ed in FIG. 2. As shown in this Figure the article engaging areas 14 form an angle "A"
with a plane perpendicu~ to base 12 of 20-30 which facilitates molding and nesting of the tray 10 itself and, more importan~ly, provides a "lead-in" for the centering of articles 26 to be stored in the tray 10. This "lead-in" is achieved by the angulation of the article engaging areas 14 wi~h the base which permi~s wide latitude in placing articles 26 into the tray 10.
Typically such articles 26 ~re placed in packing ~rays by mechanical packing devices which are diffirult to adjust and keep in adjustment. Thus, the tr~y lO of this in~ention which permits wide latitude in placement of the articles 26 in the ~ray 10 requires less adjustment of packing machinery and therefore less maintenance.
After placement of the articles 26 in the tray 10 one overall dimension of the tray 10 is reduced to bring the article engaging areas into engagement with or close proximity to the stored articles 26. This is achieved by pushing the two ends 28 and 30 of the tray 10 towards each other, for example, by placing the tray 10 on a conveyor belt which passes through an area having sidewalls which taper inward as the tray 10 passes through that area (not illus~rated). The sidewalls straddling the conveyor would push the ends ~8 and 30 of tray lO together which in turn would cause the tray lO to bend along fold lines 18, 20, 22 and 24 in accordian-like fashion.
As this occurs, angle A decreases and the ar~icle engaging areas 14 become steeper relative to the base 12. The angle A
is preEerably decreased and one overall dimension of the tray 10 decreased until the article engaging areas 14 are in engagement with or close proximity to the stored articles 26. (See FIGS. 3-6).
At this point in the packaging process the tray lO acts to secure the stored articles 26 in place within the tray lO
and isolate the stored articles 26 from each other and external forces. The latter feature is particularly important where the stored articles are made of glass or other breakable material. After the tray 10 is suitably compressed to hold the stored articles 26 in place the compressed tray may then be placed in a suitable carton 32 (see FIG. 7) or other overwrap for shipment to the consumer.
~ ~ 5 The article engaging areas 14 shown inthe embodiment of this invention illustrated in FIGS. l-S are essentially L-shaped surfaces 34 extending between fold line5 18 and 20 in the base 12 and fold lines 22 and 24 in the upper surfaee 16 (or ends 28 and 30) with projections 36 extending from ~his surface 34 into the areas betw~en adjoining articles 26 stored - in tray 10. As illustrated in FIGS. 1-6 these projections 36 are triangular shaped when viewed from the top of the tray 10, however, these projections 36 may be of any shape which will best conform to ~he shape of the stored ar~icles 26.
FIGS. 1-6 are directed ~o the practice of the invention wherein the ar~icle engaging areas 14 have projections 36 which extend into areas between adjacent stored articles 26 on two sides of such ~rticles 26. The inven~ion, however, may also be practiced in other manners. For example, FIGS. 7-9 illustrate the practice of the invention where article engaging areas 14A contain no projections but rather a cu~out 38 in one of such areas 14A which cutout generally corresponds to the configuration of the stored article 26. This cutout 38 is formed in the area between adjacent fold lines 22A and 24A in the upper surface 16A of the tray lOA of this embodiment or between one of these fold lines and end skirt 44~ In this embodiment when the overall dimension of the tray lOA is reduced the stored articles 26A are held from moving lengthwise along the tray lOA by the multipoint engagement of the cutout 38 with the stored article 26A and are restrained in the other direction by the vertical surfaces 40 and 42 of the complemen~ary article engaging area 14A (see FIG. 7). In this embodiment a single thickness of the article engagin~ area 14A separates adjoining articles stored in the tray lOA thereby maximizing the number of articles 26A which may be stored in a given tray area.
The remaining structure and f~mction of this alternate embodiment of the invention is generally similar to the prior embodiment and accordingly like reference numerals have been used f~r like parts but designated by th~ suffix l'A".
As is apparent the invention may be practieed in various manners including the particularly illustrated embodiments.
For example, v~rious configurations of article engaging areas may be utiliæed depending upon the shapes and siz~ of articles being stored and shipped in the tray.
While the above embodiments canstitute the presently preferred mode of practicing thls invention, other embodiments and equivalents are within the scope of the actual invention, which is set forth in the claims which follow.
