signor to Continental Can Company, New York, N. a corporation of New York Filed Oct. 12, 1960, Ser. No. 62,288' 13 Claims. (Cl. 20665) This invention relates in general to new and useful improvements in can holders, and more particularly to a novel can holder for holding cans of different heights.

In the past, there have been devised various types of can holders, many of which are formed of a paperboard product. However, these prior can holders have all dealt with cans of the same size. While in most instances, a number of cans of the same product are packaged together for multiple purchase distribution, there are instances where it is desired to package different products in a single package and wherein the products are packaged in containers of difierent sizes, for example, different heights, the package being intended for the purpose of introducing a product in conjunction with other known products, or for the purpose of making an attractive offer of related products. It is to this end that it is a primary object of the invention to provide a novel can holder which will engage cans and like beaded containers and hold the cans assembled in a package form for the distribution as a unit of a plurality of cans and wherein at least one of the cans is of a different height from the others of the cans being distributed.

Another object of the invention is to provide a novel holder for holding a plurality of beaded containers in a row for handling as a single package, the holder being formed from suitable paperboard material and serving not only as a package forming member, but also as an attractive display device for displaying the individual containers of the package.

Still another object of the invention is to provide a novel can holder which is particularly adapted for holding cans of different heights, the can holder having a unitary base on which all of the cans of the package rest, an upstanding rear wall, and individual top walls, which top walls are engaged over the upper ends of the respective ones of the cans, and the rear wall tyign together the base and the top walls to securely hold the cans together as a unit in a single package.

A further object of the invention is to provide a novel package formed of three cans or other similarly beaded containers, one of which is of a different height from the others and is disposed intermediate the others, and a can holder partially wrapped around the cans and securing the cans together in a row as a single unit, the cans being interlocked with a base portion of the can holder and with individual top walls thereof wherein any twisting movement of the cans relative to each other or to the holder is resisted by the can holder and the interlock between the individual can and the can holder is increased, and the cans are removable from the can holder only through a tearing of the can holder.

Still another object of the invention is to provide a novel blank for forming a can holder for the holding of three cans, one of which cans is of a different height from the others, the blank being in the form of a paperboard product and generally rectangular in outline, the blank also being provided with suitable score lines and cuts so as to define generally a unitary base, an upstanding Wall and individual top walls, the construction of the base and top walls being of a nature to provide an interlock with beaded ends of cans when the blank is shaped into a can holder and is partially wrapped around the cans to form a package.

These together with the other objects and advantages Patented Sept. 1, 1964 which will become apparent as the following description proceeds reside in the construction and arrangement of parts as more fully set forthin the following description and appended claims and illustrated in the accompanying drawings:

In the drawings:

FIGURE 1 is a perspective view showing a package in accordance with the invention, wherein the package is formed of three cans, the central one of the cans being of a different height from the others and the cans being assembled together in a rigid unit through the use of the can holder.

FIGURE 2 is a rear perspective view of the can holder of FIGURE 1 with an endmost one of the cans being omitted and the top wall normally overlying the removed can being swung to a rearwardlydisposed position in order to further illustrate the details of the can holder.

FIGURE 3 is an enlarged vertical sectional view taken along the line 33 of FIGURE 1, and shows the specific relationship of the can holder with respect to one of the cans, including the interlock between the beaded ends of the can and the can holder.

FIGURE 4 is an enlarged horizontal sectional view taken along the line 4-4 of FIGURE 1, and shows the alignment of the cans within the can holder and the interlocking of the flanges and rear wall of the can holder with the beads of the cans.

FIGURE 5 is a plan view on a reduced scale showing the specificdetails of the blank from which the can holder is formed.

Reference is now made to the drawings in detail, wherein there is illustrated in FIGURE 1 a package formed in accordance with the invention, the package being generally referred to by the numeral 10. The package 10 is formed of three

cans

11', 12 and 13, and a can holder, generally referred to-by the numeral 14. The

cans

11, 12, and 13 are disposed in a row, with the

cans

11 and 13 being disposed outermost andof the same size. The central can 12 is of the same diameter as the

cans

11, 13, but is of a different height. As illustrated, the can 12' is taller than the

cans

11, 13, although it is feasible in accordance with the invention that the can 12 could be shorter than the

cans

11, 13.

At this time,,it is pointed outthat the

cans

11, 12 and 13 are conventional cans, and have beaded end portions formed by the usual double seams connecting; the can ends to the can body. Each can 11, 12 and 13' has a lower bead 15 and an upper bead 16, which beads are identical, and with which beads the can holder 14 interlocks in the formation of the package 10, in a manner to be described in detail hereinafter.

The specific details of the can holder 14 may be best described by first making reference to the blank of FIG- URE 5, the blank being generally referred to by the numeral 17. The blank 17, for economy purposes, is a paperboard product. So, when the can holder 14 is intended to function solely for the purpose of holding the cans together in a package, it may be plain. However, normally the surface of the blank which is to be disposed outermost when the can holder 14 is formed therefrom will be provided with suitable ornamentation thereon for descriptive and/ or sales appeal purposes.

The blank 17'is generally rectangular in outline and has

side edges

18, 19 and a straight end 20. A first set of

score lines

21, 22 extend across the blank 17 between the

side edges

18,19 adjacent to and in parallel relation to the end 20. The

score lines

21, 22 are interrupted by generally C-shaped cuts 23 which are equally spaced and which correspond in position generally to the positions of the

cans

11, 12 and 13 when disposed in a row. A major portion of each of the 'C-shaped cuts 23 lies along the line of the score line 21, and together with 3 the score line 21 defines a flange 24 which is relatively narrow. The free corners of the flange 24 are rounded, as at 25. The portion of the blank 19 intermediate the

score lines

21, 22 defines connecting straps 26.

The portion of the blank 17 adjacent the flange 24 is in the form of a base 27. The base 27 is defined along one side thereof by the score line 22 and the cut lines 23. The opposite edge of the base 27 is in part defined by an interrupted score line 28 which, together with a closely spaced score line 29, extends transversely of the blank 17 between the

side edges

18, 19. The base 27 is also in part defined by cut lines 30 which are disposed between interrupted portions of the score lines 28, 29. It is to be noted that a major portion of each out line 30 is disposed along the line of the score lines 29. The portions of the blank 17 at the ends of the cut lines 30 and intermediate the score lines 28, 29 are in the form of straps 31. The straps 31 connect the base 27 to a rear wall 32 which is formed by a next part of the blank 17, whereas the connecting straps 26 connect the base 27 to the flange 24. It is to be noted that the base 27 has

projections

33, 34 disposed along opposite sides thereof and defined by the

cut lines

23, 30, respectively.

A set of

interrupted score lines

35, 36 extends inwardly from the side edge 18 of the blank 17. Another set of

score lines

37, 38 extends inwardly from the side edge 19 of the blank. The

score lines

35 and 37 are in alignment, and the

score lines

36 and 38 are in alignment. The inner portions of the

score lines

35, 36, 37 and 38 terminate substantially at the third points. The

score lines

35 and 36 are interrupted by an intermediate generally C-shaped out line 39 which has a major portion thereof aligned with the score lines 35. A similar C-shaped cut line 40 is disposed intermediate portions of the

score lines

37 and 38 and has the major portion thereof disposed along the score line 37.

The blank 17 has a pair of longitudinally extending straight out

lines

41, 42 which are disposed generally along the longitudinal third lines of the blank 17. The out line 41 opens through the end of the blank 17 remote from the end 20 and terminates at its inner end at the score line 35. The out line 42 similarly opens through the end of the blank 17 remote from the end 20 and terminates at its inner end at the score line 37.

Interrupted score lines

43, 44 extend between the

cut lines

41, 42 in offset relation to the

score lines

35, 37 and 36, 38. The 'C-shaped out line 45 is disposed intermediate portions of the

score lines

43, 44 and has a major portion thereof disposed along the score line 43.

Due to the arrangement of the

score lines

35, 37 and 43 and the

cut lines

39, 40 and 45, the rear wall 32 will have an irregular upper edge wherein the intermediate portion is disposed above the outer portions thereof. This differential in height in the various portions of the rear wall 32 permits the accommodation of a central can 12 which is higher than the

cans

11, 13. Of course, if the center can were shorter than the outer cans, then, the relationship of the edge portions of the rear wall 32 would be reversed.

The portion of the blank 17 to the left of the out line 41 and adjacent the rear wall 32 is in the form of a top wall 46. The wall 46 is bounded along one side by the score line 36 and the cut line 39 and along the other side thereof in part by an interrupted score line 47 which extends between the side edge 18 and the cut line 41. Associated with the score line 47 is a second score line 48. The score line 48 is also interrupted, with the interruption of the score lines 47 and 48 being in the form of a generally C-shaped out line 49, the major portion of which out line is disposed along the line of the score line 48. The out line 49 also in part defines a side edge of the top wall 46. The score line 48 and the central portion of the cut line 49 also define a partial flange 50.

It is to be noted that the portions of the blank 17 disposed intermediate the portions of the score lines 35, 36 are in the form of connecting straps 51 which connect the top wall 46 to a corresponding portion of the rear wall 32. Also, the portions of the blank 17 intermediate the interrupted portions of the score lines 47, 48 are in the form of connecting straps 52 which connect the flange to the top wall 46. The cut lines 39 and 49 also define

projections

53, 54, respectively, extending from opposite sides of the top wall 46.

Score lines

55, 56 extend transversely across the blank 17 in alignment with the score lines 47 and 48, the score lines 55, 56 extending between the out line 42 and the side edge 19. The score lines 55, 56 are interrupted by a generally C-shaped cut 57 which has a major portion thereof extending along the score line 56. The score line 38, together with the cut 40, defines one edge of a top wall 58 which corresponds to the top wall 46, while the score line and the out line 57 define a second side edge of the top wall 58. The score line 56 and the intermediate portion of the out line 57 also defines a partial flange 59 which is connected to the top wall 58. The top wall 58 is connected to the rear wall 32 by connecting straps 60 which are disposed intermediate the portions of the score lines 37, 38. The flange 59 is connected to the top wall 58 by connecting straps 61 which extend between the interrupted portions of

score lines

55, 56. The cut lines 40, 57 define projections 62, 63 at the opposite sides of the top wall 58.

An interrupted score line 64 extends transversely of the blank 17 intermediate the cut lines 41, 42. The spacing between the score line 44 and the score line 64 corresponds generally to the spacing between the score line 36 and the score line 47 and the spacing between the score line 38 and the score line 55'. A second interrupted score line 65 is disposed adjacent to and parallel to the score line 64. A generally C-shaped cut line 66 serves as the interruption to the score lines 64, 65, with a major portion of the out line 66 lying along the score line 65.

An intermediate top wall 67 has the side edges thereof defined by the score line 44 and the out line 45 along one edge, and by the score line 64 and the cut line 66 along the opposite edge. The score line 65 and the intermediate portion of the out line 66 also defines an outer partial flange 68. The top wall 67 is connected to the rear wall 32 by connecting straps 69 which are disposed intermediate adjacent portions of the score lines 43, 44. The flange 68 is connected to the top wall 67 by connecting straps 70 which are disposed between adjacent portions of the score lines 64, 65. The cut line 45 defines a projection 71 along one edges of the top wall 67 and the out line 66 defines a projection '72 along the opposite edge of the top wall 67.

In the use of the can holder 14, While the blank 17 is still in its flat state, the three

cans

11, 12 and 13 which are to be combined into the package 10, are set on the base 27 in alignment with each other and the base 27. The flange 24 and the rear wall 32 are then swung upwardly to vertical positions, such as is shown in FIG- URE 1. The upward folding of the flange 24 results in the formation of openings 73 in the lower edge of the flange 24 coextensive with the projections 33 of the base 27. The adjacent portions of the lower beads 15 of the

cans

11, 12 and 13 project through the openings '73 and the flange 24 interlocks over the lower beads 15 to prevent upward movement of the

cans

11, 12 and 13.

When the rear wall 32 is swung upwardly to its vertical position, openings 74 are formed in the lower edge thereof, which openings are coextensive with the projections 34 and into which the lower beads 15 of the

cans

11, 12 and 13 project in the manner generally illustrated in FIGURE 2 to further interlock the lower portions of the

cans

11, 12 and 13 with the can holder 14 to prevent upward movement of the cans.

The

top walls

46, 58 and 67 are then swung over the upper ends of the

cans

11, 12 and 13, and the

partial flanges

50, 59 and 68 are swung downwardly into alignment with the continuous flange 24, as is best shown in FIGURE 1. When the top Wall 46 is swung in place overlying the can 11, an opening 75 is formed at the upper edge of the rear wall 32 in alignment with the projection 53 and the upper head 16 of the can 11 projects through the opening 75 and overlies the upper edge of the rear Wall 32 to form an interlocktherewith. A similar opening will be formed coextensive with the projection 62 when the top wall 58 is swung into overlying relation with respect to the can 13. This latter opening is referred to by th enumeral 76 and is illustrated in FIG- URE 3.

When the top wall 67 is swung into, overlying relation with respect to the can 12, an opening 77 is formed at the upper edge of the rear wall 32 in alignment with the projection 71. The top head 16 of the can 12 projects through the opening 77 and the rear wall 32 is interlocked beneath the top bead 16 of thecan 12.

When the

flanges

50, 59 and 68 are moved into their vertical positions to complete the formation of the package 10,. similar openings to those described above will be formed in alignment with the

projections

54, 63 and 72. The opening aligned with the projection 54 is referred to by the numeral 78 and receives the top bead 16 of the can 11.. The opening aligned with the projection 72 is referred to by the numeral 79 and receives the top bead 16 of the can 12. Similarly, the opening aligned with the projection 63 is referred. to by the numeral 80 and receives the top bead of the can 13. The

flanges

50, 59 and 68 are locked beneath the top beads of their respective cans and prevent relative downward movement thereof.

It is to be understood that when the

cans

11, 12 and 13' are snapped into place within the can holder 14, the interlock between the cans and the can holder becomes a very firm one due to the relative dimensions of the cans and the can holder. As a result, a very rigid package is formed, which package is tightened by any tendency of the cans to move relative to each other and to the can holder 14. The interlock between the cans and the can holder is such that it is necessary to at least in part tear the can holder in order to remove one of the cans. When the

cans

11, 12 and 13 are engaged within the can holder 14,. the various connecting

straps

26, 31, 52, 53, 60, 61, 69 and 70 assume diagonal positions, as is best shown in FIGURES l, 2, and thus provide the desired interlock.

At this time, attention is directed to the fact that each of the

cans

11, 12. and 13 is readily accessible and may be removed from the holder 14 without disturbing the other cans. For example, when the can 13 is to be removed, the flange 59 is pulled outwardly and upwardly to clear the associated portion of the top bead 16 of the can 13. The top will 58 is then free for upward swinging movement to completely release the top bead 16. The can 13 may then be readily manipulated to release the lower bead thereof. The package 10 with the can 13 removed is shown in FIGURE 2.

From the foregoing, it will be readily apparent that the can holder 14 is particularly adapted to receive two cans of the same height and av third can of a different height, with the two similar cans being disposed at the opposite ends of the can. holder. Not only does the can holder provide for a rigid package, but also provides for suitable space for ornamentation either of a descriptive nature or a sales appeal nature. In addition, the front portions of the cans are left exposed so that the labels thereof may be easily read, thus adding to the attractiveness of the completed package.

From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out the desired end. However, attention is directed to the fact that variations may be made in the example structure disclosed herein without departing from the spirit and scope of the invention, as defined in the appended claims.
