6 Claims, 11 Drawing Figures 1 TWO PIECE STORAGE AND SHIPPING CARTON BACKGROUND OF THE INVENTION Except for the storage and shipping case as disclosed by the US. application for patent of Lee E. Russell,

SUMMARY It is a primary object of the present invention to provide a two part carton or case including a tray section which, after filling, will function as a storage section until the contents are ready to be repacked or labeled and sealed for shipment by application of the lid section thereto, all of which can be accomplished with a minimum of labor and without damage to the carton sections.

Another object of the invention is to provide a carton wherein the tray and lid sections may be of different colors and printed each in two colors different from the two colors of the other section, utilizing a single two color press.

A further object of the invention is to provide a two part carton the sections of which may be of different strengths as, for example, comprising one section formed of a heavier cardboard than the other or of a different number of plies.

Still another object of the invention is to provide a carton having walls of different thicknesses or plies to provide maximum stacking characteristics at a minimum of cost, and which eliminates flap waste in the top and bottom as in top and bottom opening conventional containers.

Another object of the invention is to provide a lid having abutting wall edges to substantially increase weight sustaining strength of the assembled case.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating presently preferred embodiments thereof, and wherein:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring more specifically to the drawings, and first with reference to FIG. l, the two piece carton or case as disclosed therein is designated generally 12 and includes a bottom or tray section 13 and a cover or lid section 14. The tray 13 corresponds with the tray A of application Ser. No. 158,454, heretofore referred to, including side walls 15 having inturned flaps l6 and end walls 17 which are secured to the outer sides of the flaps l6 and which terminate substantially below the upper edges of the walls 15 and flaps 16. The

walls

15 and 17 rise from the flat tray bottom, now shown in FIG. 1. i

The lid 14 includes a top wall 18, side flaps l9 and end flaps 20. The end flaps are illustrated as being wider than the side flaps l9 and of a width such that their bottom edges will abut the upper edges of the flaps 17 when the lid 14 is applied to the tray 13 and its top wall is resting on the upper edges of the walls 15 and flaps 16.

The tray 13 is shown filled with receptacles 21 having upper surfaces disposed in the same plane as the upper edges of the walls 15 and flaps 16. However, receptacles or contents 21 could terminate below the upper edges of the walls 15 and flaps l6 and the assembled case 12 could still be stacked, as the lid or top 18 would still be supported by the tray 13. The flaps 19 are adhesively secured to the outer sides of the walls 15 and the flaps 20 are similarly secured to the flaps 16 by an adhesive, not shown, in the same manner as disclosed in application Ser. No. 158,454.

FIG. 2 illustrates a slightly modified embodiment of lid, designated generally 22, having end flaps or walls 23 which are wider than the side flaps or walls 24.

FIG. 3 shows a modified tray 25 having end walls 26 which are wider than the side walls 27 thereof. The end walls 26 have end extensions forming flaps 28 which are separated by slits 28' from the walls 27 and which are secured to portions of the inner sides of the walls 27, in the same manner that the flaps 16 are secured to the walls 17.

The lid 22 can be utilized with the tray 25 and the end walls 23 can be adhesively secured to the outer sides of the end walls 26 to form a carton having end walls of double thickness for increased stacking strength. The side walls 24 are adhesively secured to portions of the flaps 28 and have their bottom edges abutting the side walls 27, when the top portion 29 of the lid is resting on the upper edges of the end walls 26 and flaps 28.

FIG. 4 illustrates the corner of a tray 30, such as the near corner of the tray 13 of FIG. 1. The tray 30 differs from the tray 13 only in that each of its side walls 31 is of twice the width of the wall 15 and has a median fold line 32 enabling its upper half 33 to be folded downwardly and inwardly against the lower half thereof and to be secured thereto in any conventional manner, not, shown, as by an adhesive.

FIG. 5 is a similar view of another embodiment of the tray designated generally 34 which differs from the tray 30 in that the upper half 35 of each side wall 36 is folded outwardly and downwardly against the bottom half thereof and is likewise adhesively secured thereto.

The tray 37 of FIG. 6 differs from the tray 34 in that each side wall 38 thereof has two longitudinal fold lines 39 and 39' and is folded longitudinally to provide three

plies

40, 41 and 42. The median ply 41 is folded outwardly along the fold line 39 and secured against the ply 40 which rises from the tray bottom; and the upper or outer ply 42 is folded upwardly along the fold line 39' and is secured against the outer side of the ply 41. The

plies

41 and 42 could be initially secured together and could be folded inwardly along the fold line 39 in the same manner as the ply 33 of FIG. 4 and secured to the inner side of the ply 38.

In each of FIGS. 4, and 6, the corner flap forms an extension of only the bottom ply of the side wall which rises from the tray bottom.

FIG. 7 illustrates a corner of a lid 43 having an end wall 44, similar to the end wall 26 of FIG. 3, but which is of double width and folded along a median line 45 to provide an inner ply 46 which is folded inwardly and upwardly and secured against the inner side of the wall extensions 68 are folded inwardly and adhesively secured, along with said flaps, to the tray walls. The flaps 67 could obviously constitute side flaps and the flaps 70 end flaps.

FIG. 11 illustrates a corner of another embodiment of lid, designated generally 73, having an end flap 74 and a side flap 75. The flap 75 differs from the flaps 62 of lid 56 in that it is of the same width as the flap 74.

Y The flap 75 has beveled ends 76 each extending 44. The wall 44 could constitute one of the side walls I rather than one of the end walls of the lid 43.

FIG. 10 illustrates a corner of another lid, designated generally 47, having an end wall 48 of triple width as compared to the end wall 26 and which is folded along two

longitudinal fold lines

49 and 50, so that an intermediate ply 51 thereof abuts the outer side of the ply 52 and is disposed between said ply and the outer ply 53. The

plies

51, 52 and 53 may be secured together by an adhesive. The wall 48 could constitute one of the side walls rather than one of the end walls of the lid 47.

FIG. 8 illustrates another embodiment of the case or carton, designated generally 54, including a tray 55 and lid 56. The tray 55 differs from the tray 13 of FIG. 1 only in that its end walls 57 are the same width as its side walls 58 and the end flaps 59 thereof, so that the upper edges of the

walls

57 and 58 and flaps 59 are disposed coplanar.

The lid 56 differs from the lid 14 in that its end flaps 60 are of a width corresponding to the width of the

walls

57 and 58, so that when the top wall 61 of the lid is resting on the upper edges of

walls

57 and 58 and flaps 59 and the flaps 60 are adhesively secured against the outer sides of the end walls 57, said flaps 60 will combine with the walls 57 to providea carton having end walls of double thickness for increased stacking strength.

The lid 56 has narrower side flaps 62 which differ from the side flaps 19 in that the flaps 62 have beveled ends 63. The lid 56 also differs from lid 14 in that the end flaps 60. include extensions 64 which are inturned and which have beveled upper ends 65 which abut the beveled ends 63 when the

flaps

62 and 64 are secured to'portions of the outer sides of the walls 58 by the adhesive coating 66. The abutting flap edges 63 and 65 materially enhance the weight sustaining strength of the carton 54 for the purpose of stacking.

FIG. 9 illustrates a slightly different embodiment of lid, designated generally 66, including end walls 67 having extensions 68 provided with beveled inner edges 69, and side walls 70 having beveled end portions 71. The

adjacent edge portions

69 and 71 of the extensions 68 and flaps 70 will assume abutting engagement with one another when flaps 67 and 70 are folded to assume positions perpendicular to the top 72 of the lid and the throughout a part of its width from the lid top 77. The flap 74 has end extensions 78each having a beveled upper edge portion 79 which abuts flush against the beveled edge 76, when the

flaps

74 and 75 and extension 78 are adhesively secured to the outer sides of the side and end walls of a tray, to provide the added stacking strength heretofore described. The flap 74 could 'obviously constitute one of the side flaps and the flap 75 one of the end flaps.

Conventional cartons and'cases containing cans become enlarged when stacked due to the can rims impressing the case walls against which they are disposed. The compressed wall areas cause said walls to become enlarged so that the cans are loose in the carton or case after the case has-been opened for labeling or repacking the cans and rescaled. With the cartons or

cases

12 and 54 of the present invention, the lids are not utilized while the unlabeled cans are in storage and when subsequently applied, after labeling or repacking of the cans, the lid will draw in the side and end walls of the enlarged tray when sealed thereto to provide a carton in which the cans are tightly packed.

Various modifications and changes are contemplated and may be resorted to without departing from the function or scope of the invention.

We claim as our invention:

1. A storage and shipping carton comprising a one piece bottom or tray section and a one piece lid or cover section; said tray section having a central portion defining a rectangular bottom, side and end walls surrounding said bottom and extending upwardly therefrom, certain of said walls having end extensions defining inturned flaps disposed against portions of inner sides of other of the walls, adhesive means securing said flaps to said wall portions; said lid section including a top wall of substantially the same dimensions as said bottom and resting upon the upper edges of certain of the tray walls, said lid section having flaps depending from the edges of said top wall and provided with adhesive means for securement of the flaps to exterior portions of the tray walls to complete the shipping carton, certain of said lid flaps being of a width corresponding to the width of the tray walls engaged thereby to provide a carton having certain walls of double thickness to facilitate stacking, and other of the lid flaps being adhesively secured to said inturned flaps of the tray section and having bottom edges resting on the upper edges of other of the tray walls.
