Description
REINFORCED CARTONS
BACKGROUND
[00011 Cartons are typically shipped in bulk quantities. During shipping, the cartons may be vertically stacked upon each other in order to maximize the amount of product shipped in a particular vessel. The amount of product shipped may depend, however, on the load-bearing capacity of the stacked cartons. It is therefore desirable to produce cartons having high rigidity and/or strength in compression for shipping, and for other purposes such as the protection of the carton contents in general.
[00021 A conventional method for increasing the strength of a carton is to produce the carton from a blank of a different, stronger board material, or to produce the blank from the same carton material but of greater thickness. Such methods typically increase the costs associated with manufacturing the carton, with the material costs of manufacture generally increasing according to the cost of increasing the strength and/or thickness of the entire blank. Some sections of the blank, however, may not be load-bearing, and the additional costs associated with increasing the strength of non-load bearing sections of the blank are wasted.

[00261 The first reinforcing blank 8 has a perimeter that may be in part generally complementary to a part of the first marginal area of the primary blank 6. The first reinforcing blank 8 is meant to overlie a part of the first marginal area of the primary blank 6 in order to reinforce the blank 6. The first reinforcing blank 8 includes a strip 80 of sequentially arranged rectangular reinforcing panels 81, 82, 83, 84, 85, 86, 87, and foldably attached reinforcing end flaps 62', 22', 32', 32', 42', 52'. During erection, the blank 8 is placed over the primary blank 6 so that the reinforcing end flaps 62', 22', 32', 32', 42', 52' of the first reinforcing blank 8 overlie and generally conform in shape to corresponding end flaps 62, 22, 32, 32, 42, 52, respectively, of the primary blank 6. The
4 sequentially arranged reinforcing panels 81, 82, 83, 84, 85, 86, 87 are aligned with respective panels 60, 20, 30, 40, 50, 70 of the primary blank 6 so that the reinforcing blank 9 folds along the transverse fold lines 61, 31, 35, 41, 51, 71 in the primary blank 6.
100271 Similarly, the second reinforcing blank 9 has a shape that may be in part generally complementary to a part of the second marginal area of the primary blank 6, and is meant to overlie and reinforce a second part of the first blank 6. The second reinforcing blank 9 includes a strip 90 of sequentially arranged rectangular reinforcing panels 91, 92, 93, 94, 95, 96, 97, and reinforcing end flaps 62', 22', 32', 32', 42', 52'.
During erection, the second reinforcing blank 9 is placed over the primary blank 6 so that the reinforcing end flaps 62', 22', 32', 32', 42', 52' of the reinforcing blank 9 overlie and generally conform in shape to the end flaps 62, 22, 32, 32, 42, 52 of the primary blank 6.
The reinforcing panels 91, 92, 93, 94, 95, 96, 97 are aligned with respective panels 60, 20, 30, 40, 50, 70 of the primary blank 6 so that the second reinforcing blank 9 folds along the transverse fold lines 61, 31, 35, 41, 51, 71 of the primary blank 6.
Portions of the second reinforcing blank 9 may be, for example, a mirror image of the first reinforcing blank 8, and certain common reference numerals are therefore used in the reinforcing blanks 8 and 9.
[00281 FIG. 1B illustrates the primary blank 6 and the reinforcing blanks 8, 9 combined into a multi-ply blank 10. In FIG. 111, the reinforcing blanks 8, 9 are placed over the respective first and second marginal areas of the primary blank 6 and secured thereto 6. The first and second distal side end flaps 24, 44 at each end of the primary blank 6 extend beyond the edges of the reinforcing blanks 8, 9. Glue, for example, or other adhesives, or other means, may be used to secure the reinforcing blanks 8, 9 to the primary blank.

The interior sides of the distal side end flaps 24, 44 are then in a position to be adhered to the interior sides of the reinforcing end flaps 22', 42', respectively.
[00401 Referring to FIGS. 12C and 12D, the exterior sides of the end flaps 32, 52 may be adhered to the second distal side end flaps 44, and the exterior sides of the end flaps 32, 62 may be adhered to the first distal side end flaps 24. FIG. 12E
illustrates closing of the opposite sides of the carton so that the third top panel 70 can be adhered to the second top panel 60.
[00411 According to the above embodiments, a primary blank can be reinforced at selected locations by reinforcing blanks. The carton formed from the resulting multi-ply blank can accordingly have enhanced strength and rigidity at selected sections of the carton. According to the present invention, selected reinforcement of specific areas of the primary blank can produce a high strength carton while using relatively small amounts of board.
[00421 One or more of the reinforcing blanks discussed above may be omitted in the above embodiments, for example, if a lesser amount of reinforcement is sufficient for a particular application.
100431 In accordance with the exemplary embodiments, the cartons may be constructed of paperboard, for example. The blanks, and thus the cartons, can also be constructed of other materials, such as cardboard, solid unbleached sulfate (SUS) board, or any other material having properties suitable for enabling the carton to function at least generally as described above.
[00441 In one exemplary embodiment, the primary and reinforcing blanks are formed from SUS board. The primary blank has a caliper in the range of about 14-30 point, which may be more specifically in the range of about 18-26 point. The caliper of the reinforcing blanks can be slightly less than the primary blank, and can be in the range of about 14-20 point.
100451 The blanks can also be laminated to or coated with one or more additional sheet-like materials at selected panels or panel sections. One or more panels of the blanks discussed above can be coated with varnish, clay, or other materials, either alone or in combination. The coating may then be printed over with product, advertising, and other information or images. The blanks may also be coated to protect any information printed on the blanks. The blanks may be coated with, for example, a moisture barrier layer, on either or both sides of the blanks.
[00461 In accordance with the above-described embodiments of the present invention, a fold line can be any substantially linear, although not necessarily straight, line of disruption or other form of weakening that facilitates folding therealong.
[00471 In the present specification, a "panel" or "flap" need not be flat or otherwise planar. A "panel" or "flap" can, for example, comprise a plurality of interconnected generally flat or planar sections.
(0048] The above embodiments may be described as having one or more panels adhered together by glue. The term "glue" is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
100491 The foregoing description of the invention illustrates and describes the present invention. Additionally, the disclosure shows and describes only selected embodiments of the invention. but it is to be understood that the invention is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art.
