ARTICLE CARRIER 7 Filed Jan. '7, 1963 INVENTOR PRENTICE J- WOOD .FIGJ W%% a ATTORNEY United States Patent 3,169,691 ARTICLE CAR Corporation, a corporation of Ohio Filed Jan. 7, 1963, Ser. No. 249,903 4 Claims. (Cl. 229-40) This invention relates to article carriers and more particularly to carriers of the wrap-around type and has to do with the carrier itself, the blank from which the carrier is formed and the method of manufacturing the blank and of forming the wrapper about a group of articles to be packaged.

Article carriers of the type disclosed in US. Patent 2,786,572 issued March 26, 1957, on an application filed by Hermond G. Gentry and owned by the assignee of this invention ordinarily are formed of paperboard blanks which are die cut from a sheet of paperboard. Since the blanks must necessarily be accurately dimensioned in order properly to accommodate various machine operations used to form the package, it is customary to stamp out each individual blank by one cutting operation of the cutting machine. Such a procedure necessarily results in scrap material along the edges of adjacent blanks. This scrap material not only is waste in itself but it poses a problem insofar as its disposition is concerned.

Where cartons of the type disclosed in the aforementioned Gentry patent are provided with a center keel as disclosed in US. Patent 2,933,867 issued April 26, 1960, on an application filed by Hermond G. Gentry and owned by the assignee of this invention, it is sometimes difiicult to form the wrapper about a package group due to the stiffness imparted to the carton lap panels by virtue of the center keel which is disposed in generally perpendicular relation to the lap panels.

A principal object of the invention is to eliect substantial economy in the use of material used in making wrap per blanks by eliminating the scrapping of strips about each blank edge and also by nesting one blank with an adjacent blank and at the same time to configure the nested edges so as to form carton locks and a flexible center keel for the carton.

Another object of the invention is the provision of an improved method for die cutting carton blanks in which certain overall dimensions of the blank are accurately controlled and in which certain other overall dimensions may be allowed to vary thereby to effect economies in the use of material and in production time.

Still anotherobject of the invention is to provide an improved wrapper blank wherein a plurality of keel being formed about a package group.

. The invention in one form as applied to a wrap-around type of blank resides in the method of die cutting the Wrapper blank wherein certain overall dimensions are accurately controlled due to the fact that such dimensions are preserved by a single cutting stroke of the cutting die and wherein'certain other adjacent parts of the blank are not cut until a subsequent operation of the die, such subsequent operations being effective to out parts of the blank the dimensions of which may be allowed to vary within certain predetermined limits. In accordance with a facet of the invention, nested portions of the blank are particularly configured so as to form a multiple tab keel for separating two rows of packaged articles within the wrapper and at the same time are adapted to lend an unusual degree of flexibility to the carrier during the period of its formation about the package group.

a to be packaged itis secured by means of locking tabs 49,-

41, 42 and 43 which are inserted respectively into the For a better understanding of the invention reference may be had to the following detailed description taken in conjunction with the accompanying drawings in which FIG. 1 is a perspective view of a package formed from a wrapper constructed according to the invention; FIG. 2 is a plan view of a blank formed according to the invention and depicted inFIG. 1; and in which FIG. 3 is an enlarged fragmentary view of one end of the blank as depicted in FIG. 2 shown in solid lines in nested relation to the other end of an adjacent blank shown in dotted lines.

With reference to FIGS. 1 and 2, the numeral 1 is used to designate the main panel of the blank. As shown in PEG. 1 main panel 1 is the top of the package although it will be understood that main panel 1 could constitute the bottom or even one of the sides of the package. Main panel 1 is provided with a tear aperture 2 which com-- torn away along the perforated lines 4 and 5 in order to open the package. Also formed in main panel 1 is a pair of finger gripping tabs 6 and 7 which are struck out of the main panel 1 and foldably joined thereto along fold lines-8 and 9, respectively. As is well known these tabs 6 and 7 define finger gripping apertures by which the package may be readily carried. Also formed in the main panel 1 is a plurality of partitioning

tabs

10, 11 and 12 which are struck out of the main panel and foldably joined thereto along the

fold lines

13, 14 and 15. As is well understood in the art these tabs are folded inwardly and serve to separate the packaged articles in one row from adjacent articles in the other row.

1 Foldably joined to one edge of the main panel 1 along fold line 16 is a side panel 17. Disposed along fold line 16 is a plurality of

slits

18, 19 and 20. As is well known the

slits

18, 19 and 20 receive the chimes of cans which may constitute the packaged items. Foldably joined to the opposite edge of the main panel 1 along fold line 21 is the side panel 22. Formed along the fold line 21 is a plurality of

chime receiving slits

23, 24, and 25.

As is best shown in FIG. 1 the bottom of the carton as there depicted is a composite panel formed of a pair of

lap panels

26 and 27. As is clearly shown in FIG. 2, lap panel 26 is foldably joined to the bottom edge of side panel 17 by fold line 28 and a plurality of chime receiving slits 29, 3d and 31 are formed along the fold line 28. In like fashion lap panel 27 is foldably joined to the bottom of side panel 22 along fold line 32 and slits 33, 34 and 35 are formed along fold 1ine32.

, For the purpose of enabling machine elements to tighten the wrapper blank about a group of packaged items, tightening apertures are formed in lap panel 26 and are designated by the

numerals

36 and 37. In like fashion tightening apertures 38 and $9 are formed in lap panel 27. Machine elements enter

apertures

36 and 37 and draw lap panel 26 toward lap panel '27 while machine elements which are disposed within

tighteningapertures

38 and 39 draw lap panel 27 toward lap panel 26 in parallel relation.

After the wrapper is tightened about a group of articles openings defined by retaining

tabs

44, 45, 46 and 47.respectively. The particular cooperation of the locking and retaining tabs is disclosed in the aforementioned Gentry Patent 2,786,572. It will be understood of course that panel 26 is disposed inwardly of panel 27 so that machine packaged therein. r

panel 54 and a similar reinforcing panel 55 is interposed.

between keel tabs 49 and t). Keel tab 48 is separated.

from the main body of lap panel 26 by a slit S5 and fromthe adjacent edge of reinforcing panel 54b slit 57. In

like fashion slits

58 and 59 separate keel tab from reinforcing

panels

54 and 55 while slit es separates reinforcing panel 55 from keel tab 5t? and slit ol'separates keel tab 5i from the main body of lap panel 26'. Thus the

keel tabs

43, 49 and 5t arefreely foldable inwardly along their .fold lines 51, 52-and 53 respectively to form multiple separators for the bottoms of the packaged articles in one row and the articles in the adjacent row.

From the description thus far it is obvious that the

tabs

48, 49 and 5t) condition the lap panel 26 for ready flexibility and thereby greatly facilitate the formation of the wrapper about a group of packaged items.

In accordancewith one facet of the

invention reinforcing panels

54 and 55 are disposed immediately adjacent the openings defined by retaining tabs 45 and 4-5. These reinforcing

panels

54 and 55 lie fiat in the same plane as the main body of lap panel 25 and whenthe locking tabs 41 and 42 are inserted within the openings defined by retaining

tabs

45 and 46 substantial added strength isjaiforded by

thereinforcing panels

54 and 55. The strength added by the

flat panels

54 and 55 is considerably greater than the strength of a common center keel wherein the entire keel is disposed in mal relation to the lap panel 26. V

i In accordance with another facet of the invention, sub stantial economies of material andproduction time are effected by the invention due to the fact that one end of the generally nor- In'FIG. 3 the end of tab n; is shown coinciding with the end 72 of hinge line 53 and with end '73 of hinge line 52. This is an incidental showing and it will be understood that such coincidence is not necessary. Likewise,

the end of tab 451 may but need not coincide with a line connecting points '74 and 7e. 7

From the above description it is'apparent that sub- 7 stantial economy of material and of production time are effected and atthe same time flexibility of the wrapper during the formation of the package is improved and added strength 'is impartedto the finished wrapper when incorporated into .a complete package.

While-I have shown and described a particul'ar'form of the invention, 'Ido not wish to be limited thereto and intendin the appended claims to cover all changes and modifications which fall within the true spirit and scope of the invention.

The embodiments of the invention in which an exelusive property or privilege is claimed'are defined as follows: i i

l. A wrapper blank comprising a main panel, a pair of side panels foldably joined respectively along opposite edges of said main panel, a pair of lap panels foldably joined respectively to said side panels along the edges thereof remote from said main panel, at least one protrusion formed on the edge of one of said lap panels remote from the associated side panel, a locking tab formed at least partially within said protrusion, at least two keel blank as depicted in FIG; 2 can be nested-with an adjacent end of an adjacent blank so as to eliminate material wastage. without impairing the dimensional control of the blank. More specifically it is necessary to niaintain'accurate dimensioning between the outwardly extending edges 62 and i 63 of the

protrusions

64 and 65 formed along one edge of lap panel 27 and the

outer edges

65, 67 and as of the

keel tabs

48, 49 and 50, respectively. For this reason it is necessary to die cut the lines 66-68 and 62 and 63 by a single stroke of the cutting die.
