11 Claims, 7 Drawing Figures PATENTEU AUG 1 9 I975 SliCiT 2 UF 2 TRAPEZOIDAL CONTAINER HAVING END-FLAPS THAT WEDGINGLY ENTRAP A TRAY This invention relates in general to new and useful improvements in containers or cartons, and more particularly to a container or carton particularly adapted for packaging a tray having packed therein a plurality of articles in a manner wherein the tray will remain stationary within the carton.

Normally, containers or cartons are rectangular in cross section. However, when an article other than an rectangular article is to be shipped within such a container, it is necessary to provide suitable spacers within the container in order to prevent shifting of the article therein.

The present invention relates primarily to the problem of packing a tray which has packed therein a plurality of articles, in a manner wherein the tray and packed articles will not shift relative to the container. This is necessary in that when individual packages are shipped, especially by parcel post, the packages are relatively roughly handled and frequently inverted.

In accordance with this invention, the foregoing problem has been solved by providing a container which in one transverse cross section is trapezoidal and thus has sloping ends. The net result is that after the packed tray is slid into the carton through one open end thereof, and that end is closed, the tray is wedged against the bottom wall of the carton by the trapezoidal configuration thereof.

Another feature of the invention is that the open end of the carton is closed by a plurality of flaps which sequentially overlap one another with certain of the flaps being dismensioned to be disposed above the upper surface of the tray and thus form a stationary abutment against which the tray is engaged so as to firmly hold the tray against the bottom wall of the carton.

Another feature of the invention is the fact that the carton blank may be formed from the same size stock as a regular rectangular carton of the size necessary to package the packed tray.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings:

In the drawing:

FIG. I is a plan view ofa carton blank for forming the carton or container of this invention.

FIG. 2 is a fragmentary perspective view of the erected carton with one end thereof open ready for the reception of a packed tray.

FIG. 3 is a view similar to FIG. 2 and shows a tray being moved into the open carton.

FIG. 4 is a view similar to FIG. 2 showing the first step in closing the open end of the carton.

FIG. 5 is a view similar to FIG. 4 showing the second step in closing the open end of the carton.

FIG. 6 is a perspective view of the completed package.

FIG. 7 is an exaggerated enlarged transverse sectional view taken along the line 7--7 of FIG. 6 and shows the specific relationship of the carton with respect to the packed tray and the manner in which the tray is retained in a fixed position within the carton.

Referring now to the drawings in detail, it will be seen that there is illustrated in FIG. 1 the blank for forming the carton of this invention, the carton blank being generally identified by the numeral 10. The carton blank 10 is of a one piece construction and is preferably die cut from corrugated board. I

In the preferred embodiment of the carton blank 10, a rectangular bottom panel 11 is disposed adjacent one end of the carton blank 10 and is connected by means of a transverse fold line 12 to a trapezoidal outline side panel 13. A rectangular bottom panel 14 is connected to the side panel 13 along a transverse fold line 15. The bottom panel 14 is of a lesser transverse dimension than the bottom panel 11 but is of the same length. A second trapezoidal side panel 16 is connected to the top panel 14 along a transverse fold line 17.

The carton blank 10 also includes a securing flap 18 which in the illustrated form of the invention is connected to the bottom panel 11 along a transverse fold line 20, but in certain instances, could be connected to the side panel 16.

The carton blank 10 also includes a pair of closure 3 flaps 21 which extend transversely from the side panel 13. The longitudinal dimension of the flaps 21 is less than that of the side panel 13 and the flaps 21 are connected to the side panel 13 adjacent the fold line 15 remote from the bottom panel 11. The flaps 21 are connected to the side panel 13 along fold lines 22.

A similar pair of flaps 23 extend transversely from the side panel 16 and like the flaps 21 are of a lesser longitudinal dimension than the side panel 16. The flaps 23 are connected to the side panel 16 along fold lines 24 and are positioned closely adjacent the fold line 17.

A second set of end closure flaps 25 extend transversely from the top panel 14 and are connected thereto along fold lines 26. It is to be noted that the transverse dimension of the flaps 25 is substantially equal to the longitudinal dimension of the flaps 21, 23.

Finally, the carton blank 10 includes a pair of end panels 27 which extend transversely from opposite sides of the bottom panel 11 and are connected thereto along fold lines 28. It is to be noted that the transverse dimension of the end panels 27 is greater than that of the flaps 25 so that the end panels 27 extend substantially the fully height of the resultant carton.

Referring now to FIG. 2, it is to be understood that a carton 30, which is formed from the carton blank 10 is formed by a folding of the blank generally at right angles along the fold lines 20, 12, 15 and 17 and by suitably securing the flap 18 against the outer surface of the side panel 16 such as by an adhesive (not shown). If desired, one end of the carton 30 may be closed in advance of the packaging of a product therein.

The carton 30 is particularly configurated for the packaging therein of a tray 31 in which there is securely packed articles 32 (FIG. 7) securely fixed relative to the tray 31. The tray 31 is of a rigid construction and includes a bottom wall 33 which has upstanding from opposite sides thereof side walls 34. The ends of the tray 30 are of a folded double thickness construction and are identified by the numeral 35.

Referring now to FIG. 3, it will be seen that the packed tray 31 is slid into the partially closed carton 30 through one thereof, and that the width of the tray 31 is such that the side walls 34 thereof closely contact the inner surfaces of the side panels 13 and 16 of the carton 30. Thus, the tray 31 is prevented from shifting transversely within the carton 30.

After the packed tray 31 has been fully inserted within the carton 30, the flaps 21 are swung into a planar condition with the lower edges of the flaps 21 directly overlaying the upper edge of the associated end wall 35 of the tray 31. At this time it is pointed out that inasmuch as the carton 30 is formed of corrugated board, there is a certain give in the material which enables the flaps 21 to be generally twisted to the position shown in FIG. 4 although the natural hinging thereof along the fold lines 22 would require a slightly different position.

Referring now to FIG. 5, it will be seen that after the flaps 21 have been folded into place, the flap 25 is swung down about its fold line 26 with the lower edge of the flap 25 being disposed immediately above the upper edge of the end wall 35 of the tray to further lock the tray down against the bottom panel 11 of the carton. If desired, the flap 25 may be suitably adhesively secured to the flaps 21.

Thereafter, the end panel 27 is folded up into overlapping relation with respect to the flap 25. The flap 27 engages the outer surface of the end wall 35 of the tray, as is shown in FIG. 7, and prevents the longitudinal shifting of the tray within the carton 30. If desired, the end panel 27 may be suitably secured to the flap 25 such as by way of a suitable adhesive.

Reference is now made to FIG. 6 wherein the completed package, which is identified by the numeral 40, is shown. It is to be noted that the package 40 is completed by wrapping a suitable binding tape 41 longitudinally about the carton 30 and thus assuring the securing in place of the flaps and panel at each end of the carton 30. The tape 41 if desired, may be the only securing means for retaining the carton 30 in its closed condition.

Referring now to the exaggerated showing of FIG. 7, it will be seen that the tray 31 is wedgingly retained within the carton 30 by the end panels 27 so that the tray 31 cannot shift towards the ends of the carton and further to retain the tray seated on the bottom panel 11 of the carton. Further, the flaps 21 and 25 overlie the double thickness end walls 35 of the tray 31 and further retain the tray 31 seated against the bottom panel 11 of the carton. Thus, even though the package may be turned upside down during handling, the relative position of the tray and the articles packaged therein with respect to the carton will remain the same..Accordingly, the package 40 may be subjected to rather severe handling without damage to the articles packaged in the tray.

Although only a preferred embodiment of the invention has been specifically illustrated and described herein, it is to be understood that minor variations may be made in the carton construction and the relationship thereof with respect to the tray without departing from the spirit and scope of the invention, as defined by the appended claims.
