The present application claims priority, as a continuation-in-part type application, under 35 U.S.C. §120 to U.S. patent application Ser. No. 11/705,321, filed Feb. 12, 2007, currently pending. The aforementioned the U.S. patent application Ser. No. 11/705,321 is incorporated herein by reference in its entirety.
BACKGROUNDThe present disclosure relates to mailing boxes and, more particularly, to flexible postal mailers or shipping cartons and blanks therefor. The embodiments described herein are particularly well suited for flat-size mail pieces for processing by automated processing equipment commonly employed by postal services such as the United States Postal Service and others.
Commonly, automated mail processing equipment requires that flat-size mail pieces meet certain automation standards, including turning ability and deflection requirements. However, a flexible mail piece must be sufficiently rigid to meet certain deflection requirements, that is, one end must be able to extend from a surface, unsupported without deflecting by more than a prespecified amount.
Flat-size mail pieces meeting applicable standards are entitled to reduced, automation postage rates. Flat-size mail that does not meet the turning ability and deflection requirements cannot be processed by automated equipment and, thus, is more expensive to mail since it does not qualify for automation postal rates.
There are certain instances wherein a rigid box is preferred over a flexible envelope for mailing packages. For example, response rates to direct mail marketing programs are generally higher for rigid boxes than for envelopes. Also, rigid boxes generally provide better protection of the contents against damage than envelopes. However, such rigid boxes have minimal, if any flexibility. Additionally, some prior art flexible mail pieces may require that shrink wrap be used to ensure that the contents remain enclosed, with such additional packing materials being of both economic and environmental concern. Accordingly, the present disclosure contemplates a new and improved postal mailer and blank therefor which overcome the above-referenced problems and others.
SUMMARYIn one aspect, a postal mailer is provided which includes a first main panel and a second main panel opposite the first main panel, opposed first and second peripheral side panels extending between the first main panel and the second main panel, and opposed first and second end panels extending between the first main panel and the second main panel. One or more score lines extend across each of the first and second main panels and one or more openings formed in each of the first and second peripheral side panels and extending between the first and second main panels.
In another aspect, an improved postal mailer of generally box-like construction is provided having opposing first main and second main panels and opposing peripheral side walls and opposing end walls extending therebetween, wherein the improvement comprises one or more of score lines extending across the first main panel of the postal mailer, one or more of score lines extending across the second main panel of the postal mailer, and one or more openings formed in each of said peripheral side walls and extending between said one or more of score lines extending across the first main panel of the postal mailer and said one or more of score lines extending across the second main panel of the postal mailer.
In another aspect, a postal mailer blank is provided, comprising a plurality of wall panels hingedly connected together for forming a first main panel, a second main panel opposing said first main panel, opposing side walls, and opposing end walls. One or more score lines extend across said first main panel and one or more score lines extend across said second main panel. One or more openings are provided in said panels for forming one or more openings in said opposing side walls and extending between said first and second main panels.
One advantage of the presently disclosed postal mailer is found in that it allows the mail piece to retain the advantages of a rigid box while complying with flexibility requirements for automated mail processing systems.
Another advantage of the present device is that the box can bend upwards and downwards without damaging the contents.
Still another advantage of the present development is found in that may allow reduced automation postal rates to be claimed.
Yet another advantage of the present invention is found in that the amount of packaging material may be reduced in that a desired degree of flexibility can be provided in a box of relatively rugged construction, thereby avoiding the need to additional packaging materials such as shrink wrap.
Other benefits and advantages of the present disclosure will become apparent to those skilled in the art upon a reading and understanding of the preferred embodiments.
The invention may take form in various components and arrangements of components, and in various steps and arrangements of steps. The drawings, wherein like reference numerals are used for like or analogous components throughout the several views, are only for purposes of illustrating preferred embodiments and are not to be construed as limiting the invention.

The blank 31 may be cut to the desired size and peripheral shape, and the slits, openings, score lines, etc., as described herein may be formed thereon via conventional methods, such as die cutting from one or more sheets of stock material. The blank 31 includes score lines 90 and 92 defining the opposite long edges of the upper panel 32. As used herein, the term “score line” or “fold line” includes any indentation, impression, or partial perforation formed in the stock sheet material forming the blank 31 along a predetermined line and which is adapted to allow a preferential folding of the stock material therealong.
The blank 31 further includes score lines 94 and 96 defining the opposite long edges of the lower panel 34. Score lines 98 define the opposite width edges of the upper panel 32 and provide a preferential fold line between the upper panel 32 and the closure end flaps 50. Score lines 98 also provide preferential fold lines for the lateral flaps 46. Score lines 108 provide preferential fold lines for the lateral flaps 48. Score lines 100 are provided on each of the flaps 50 to provide a preferential fold line on each flap 50 between the proximal and distal portions 54 and 52, respectively. Slits 102 in the lower panel 34 define the proximal portion of the tabs 56, each of which includes proximal and distal score lines 104 and 106, respectively, forming preferential fold lines therealong.
The score lines 72 transversely extend across the upper panel 32 between the fold lines 90 and 92. The score lines 74 transversely extend across the lower panel 34 between the score lines 94 and 96. The slits 76 in the assembled mailer 30 may be preformed in the blank 31 and extend transversely between the fold lines 92 and 94 to define panels 77 therebetween. The slits 78a and 78b in the sidewall panels 38a and 38b, respectively, overlap in the assembled mailer 30 to form the slits 78 in the assembled mailer. The enlarged openings 80 in the assembled mailer are formed by the openings 80 and the cutout regions 80a and 80b which may likewise be precut on the blank 31. If openings are to be provided in the regions 82 and/or 83, such openings may be die cut or otherwise preformed in the blank 31.
In constructing the mailer 30 from the blank 31, the blank is folded at right angles along the lines 90, 92, 94, and 96 and the flaps 38a and 38b are secured together in overlapping fashion to form the side wall 38. The flaps 38a and 38b may be secured together with an adhesive, mechanical fastener, or other fastening technique. For example, in the case of a plastic or plastic-coated stock material, the flaps 38a and 38b may be thermally fused to form the sidewall 38.
To close one or both of the ends 40 and 60 of the mailer 30, the end flaps 50 are each folded along the fold lines 98 and 100. The distal portions 52 are inserted within the respective openings 42 such that the proximal portions 54 each form a peripheral end wall extending between the upper panel 32 and the lower panel 34. The tabs 56 are each folded along the lines 104 and 106 and the distal end of each tab 56 is inserted into the corresponding slot 58 in the respective end flap 50.
In constructing the assembled mailer 30, the blank 31 is not folded along the fold lines 72 and 74. The fold lines 72 and 74 remain substantially unfolded in the assembled article 30 to allow the mail piece to remain substantially rigid. Instead, the score lines 72 and 74 are intended only to provide fold lines along which the mailer 30 will preferentially bend if a bending stress is applied to the mail piece, such as during automated processing or handling of the mail piece.
The slits 76 also assist in facilitating a flexing or bending along the bending region 70 defined by the score lines 72, 74 when a bending stress is applied to the mail piece. The flexible panels 77 can flex as necessary, thereby helping to confine any flexing or bending of the mail piece 30 to the bending region 70.
