4 Claims. (Cl. 229-40) This application relates to cartons for packaging and displaying a plurality of articles, particularly articles of like dimension which are somewhat fragile.

The carton provided by this invention is particularly suited for forming a package which may be used for displaying the packaged articles without the necessity of a set-up operation or the like, and in which relatively fragile articles such as gass jars or the like may be packaged with safety. The blank for packaging the articles is of generally rectangular outline and is devoid of knockout portions or the like, thereby being relatively inexpensive to manufacture. The blank may be easilyformed into a sleeve-like container or carton which surrounds the articles and retains them securely within the carton, while openings are provided in at least one wall of the carton through which portions of the packaged articles may protrude to display their contents. The carton is, therefore, particularly suited to the packaging and displaying of a plurality of glass jars or the like containing various grocery items such as jellies, pickles, olives or the like which may be offered in groups or combinations of difierent types of the same item.

When packaging such relatively fragile articles it is necessary to separate adjacent articles from each other to avoid breakage. In fact, in some cases requirements are set forth by governmental agencies regulating the manner in which such articles must be separated during shipment. Since a number of the articles are enclosed within the carton it is necessary to provide suitable buffers between them to guard against breakage during ship ment and to comply with such regulations. In accordance with this invention these buffers are provided as parts of the carton which are folded into position between the packaged articles, thereby performing the additional function of defining the display openings in the walls of the cartons.

Accordingly, a primary object of this invention is to provide a packaging and display carton for a plurality of articles having like dimensions wherein display openings are provided in the walls of the carton extending a major portion of the height thereof, and of less width than the diameter of the articles, providing for extension of a part of each article outwardly of the carton and also providing bufiers between adjacent articles to guard against breakage.

Another object of the invention is to provide a blank for forming such a carton which is of simple and economical construction.

A further object of the invention is to provide a packaging and display carton for a plurality of cylindrical articles of like dimensions wherein display openings are formed in the walls of the carton for each of the packaged articles, and wherein the display openings are defined by flaps which fold inwardly of the carton between adjacent articles, and including extension pieces on each of those flaps extending between articles, to provide buffers of double thickness material extending a major portion of the width of the carton between adjacent articles.

2,974,851 Patented Mar. 14, 1961 a carton according to the invention;

Fig. 2 is a horizontal section through a carton formed from the blank of Fig. 1; and

Fig. 3 is a top view of the carton of Fig. 2, partially in plan and partially insection, showing the arrangement of buffers between adjacent articles.

Referring to the drawing, shown in Figs. 13 is a carton blank divided by

score lines

310, 311, 312 and 313 into foldably connected wide and narrow panels, including the top panel 315, the rear panel shown generally as 316, the bottom panel 317, a front panel indicated generally at 318, and the glue flap 319.

Both the front and rear panels are provided with openings through which jars or similar articles to be packaged may protrude, and these openings are each of lesser width than the major diameter of .the jars. The sides of the first set of such openings are defined by

score lines

320 and 321 which are connected at opposite ends by

curved slits

322, 322 and 323. The

slits

322 and 323 are intersected by a slit 325 through the rear panel 316 which defines the

complementary flaps

326 and 327, while slits 322' and 323 are intersected by a slit 330 extending generally across front panel 318 and having a curved lower edge 331'where it intersects with slit 323. This slit thus defines flaps of unequal size, the narrow flap 332 being at the end of the carton, and the other flap including the main flap portion 334 and 'a buffer portion 335 connected along a score or fold line 336.

The next set of flaps defining an opening in rear panel 316 is formed complementary to those just described in panel 318, and thus the small curved slit 340 interrupting hinge line 310, and the larger curved slit 342 interrupting hinge line 311, are joined by a longer transverse slit 343 having a curved end 344 where it intersects slit 342, providing a narrow flap 345 connected along hinge line 346 with panel 316, and a wider flap including the main flap portion 348 hinged to panel 316 along score line 349 together with a buffer 350 having a folding connection along line 351 with flap 348.

The opposed opening in front panel 318 is provided by further curved slits 342' and 340 connected by the transverse slit 343' including a curved end 344', defining the flap 345' which is hinged to the remainder of panel 318 along score line 346. It will be noted that score lines 349 and 346' are directly opposite each other. The remainder of the material is connected along score line 349' (opposite score line 346) to panel 318, and includes the main flap 348' and buffer 350' connected along score line 351'.

It will be obvious from inspection of the drawings that flaps 345', .348 and 350' correspond to

flaps

332, 334 and 335, respectively, and it will be further noted that the arrangement of

flaps

345, 348 and 350 in rear panel 316 is complementary to the opposite flaps 345', 348' and 350' in panel 318. Thus, when the carton is assembled into flaps and buffers folded to the interior of the carton between the adjacent articles, the

buffers

335 and 350 each will extend beyond a vertical plane through the center of the carton, as shown in Fig. 3, providing a double thickness of material between the adjacent articles. Obviously, the construction in each subsequent pair of opposed openings will be the same, and thus a further description is unnecessary. The final opening in panel 318 will include symmetrical panels 326' and 327' of the same type shown in the first opening in panel 316.

As will be observed particularly from the illustrations of the carton in Figs. 2 and 3, the curved or arcuate slits a such as 322, 323, 340 and .342 provide small horizontally extending tabs or platforms 360 at the top and 362 at the bottom which cover the top and bottom protruding portions of the packaged articles. Furthermore, referring particularly to Fig. 3, at leasttwo of the flaps which extend between adjacent articles will include bullies flaps or portions which extend beyond the center of the carton so as to provide a double thickness of material between adjacent articles. I

While the form of the article 'herein described constitutes the preferred embodiment of the invention, it is to be understood that the invention is not limited to the precise form of the article, and that changes may be vmade therein without departing from the scope of the fragile articles in a row with portions protruding from the carton, comprising a generally rectangular sheet of foldable material including upper and lower edges and opposed side edges, four parallel transverse score lines extending between said opposed side edges and defining between the upper and lower edges a top, first side, bottom, second side, and glue-flap panel in the order set forth, transverse cut lines extending in the direction of and along said vfour parallel score lines, said cut lines being disposed in opposed pairs at opposed marginal portions of the first and second side panels, longitudinally disposed cut lines in said side ,panels and extending diagonally between and intersecting each pair of said opposed transverse cut lines, pairs of transversely spaced and longitudinally extending score lines extending from terminal ends of said opposed pairs of transverse cut lines, said opposed pairs of transverse cut lines, diagonal cut lines, and pairs of transversely spaced score lines defining longitudinally extending adjacent pairs of foldable flaps, said diagonal cut lines in the side panels being oii-set with respect to each other and said adjacent flaps of a pair in each of said side panels including one fiap having a larger area than the other and generally tapering from end to end, the flap in one of said side panels having the larger area being disposed in opposed relation to the flap having a lesser area in the other side panel whereby in an erected blank forming the container,

the lesser area flap will be overlapped by a larger area flap when said overlapping flaps are disposed transversely of said top and bottom panels and inwardly of said side panels. a

2. The blank of claim 1; said transverse cut lines of each pair having a diiierent length, said longitudinal score lines being disposed in angular relation with respect to said four parallel score lines for defining with said adjacent pair of flaps tapering openings in said blank when the container is erected.

3. The blank of claim 2; said transversecut lines being arcuate.

4. The blank of claim 3; said arcuate cut lines ex-- tending into said side panels, the .cut lines adjacent said bottom panel having a larger radius than the arcuate cut lines adjacent said top and glue-flap panels and forming sector-shaped sections integral and coplanar with said top, bottom, and glue-flap panels.
