MXPA98002502A - Pressure seal spot pattern for c-fold mailer - Google Patents

Abstract

An intermediate for a C-fold mailer type business form is provided that does not cup or distort as a result of pressure sensitive cohesive provided on both the face and the back of the same panel. This improves the processing of the intermediate through cut sheet laser printers and post-processing equipment, and allows for easier stacking during manufacture. A sheet of paper (10) having first and second faces and opposite parallel longitudinal edges has first and second transverse fold (17, 18) lines forming a sheet into three panels (34-36), and first and second longitudinal lines of weakness (26, 27) forming longitudinal marginal portions with the longitudinal edges. A first pattern (38) (such as spaced quadrate cohesive elements) is formed in the marginal portions of the first face of the third panel while a second pattern of pressure cohesive elements (40) is formed on the second face of the marginal portions of the third panel, the second pattern of elements staggered with respect to the first pattern so that cupping or distortion of the sheet at the third panel is substantially prevented. Other patterns of pressure cohesive formed on the marginal portions cooperate with the first and second panels to seal the longitudinal edges of the mailer, the other patterns typically also comprising spaced quadrate cohesive elements. A mailer is formed from the intermediate by C-folding the sheet about the first and second fold lines.

Description

PATTERN OF POINTS WITH PRESSURE SEAL FOR ENVELOPE OF CORRESPONDENCE ENVELOPE WITH FOLD IN C BACKGROUND AND COMPENDIUM OF THE INVENTION The business forms of envelope type for mail correspondence constructed by folding a single sheet of paper in C with respect to fold lines have been popular for many years. These mailing envelopes offer the advantages of simplicity of construction, printing and use. These envelopes are particularly worthy of correspondence with double C (with or without built-in return envelopes) that are sold by Moore Business Forms Inc. under the SPEEDISEALMR brand, which uses pressure cohesive to hold together the formed panels, as illustrated - for a return envelope configuration - in the US patent No. 5,201,464 (the description of which is incorporated herein by reference). The envelope for sending correspondence with a standard C-fold that uses pressure cohesive, includes a stepped pattern of internal and external cohesive patterns in series (such as strips) on the front and back of the form. The standard pattern was created in such a way that the intermediaries of business forms will not block or adhere to each other. However, because these shapes have pressure sensitive cohesive on both the face and the back of the bottom panel, there may be a significant problem when used with some conventional cut sheet laser printers. Occasionally, a flexed edge - often referred to as a cupping or distortion - is created in the background panel as a result of cohesive patterns. This distortion can be so excessive that intermediaries can not be delivered properly on laser cut-sheet printers, or they can clog some printers. This problem can be complicated by the fact that it is convenient to provide these intermediaries with different paper weights and to be constructed of different composition. According to the present invention, an intermediary for an envelope-type business form for sending C-shaped correspondence, and an envelope-type business form for correspondence sending constituted from an intermediary, are provided, which substantially exceed the problem of clumping or distortion discussed above. The problem is solved according to the present invention by providing a different type of cohesive pressure pattern in the third panel (and cooperating other patterns that are preferably provided in the other panels). By eliminating the cupping or distortion that can occur in conventional C-fold intermediaries, according to the invention, the processing of the intermediates through cut-sheet lasers, and post-processing equipment is significantly improved, as is the ease of production of the envelopes themselves for sending correspondence with C-fold. The construction according to the invention also allows for easier stacking during fabrication. Despite the improvements provided according to the invention, the cohesive pressure pattern that is provided according to the invention allows an adequate sealing of the envelope for sending correspondence, so that it does not detach during normal handling. In accordance with one aspect of the present invention, an intermediary for an envelope-type business form is provided for sending C-shaped mail, comprising the following components: a sheet of paper having a first face adapted to provide the Most of the inside of the envelope for sending correspondence when it is built, and a second face adapted to provide the majority of the outside of the envelope for mailing when it is constructed.

First and second longitudinal weakening lines formed in the sheet parallel to and adjacent, but transversely spaced from, the longitudinal edges, the lines of weakness define, with the longitudinal edges, longitudinal marginal portions. A first pattern of longitudinally spaced pressure cohesive elements formed in the marginal portions on the first face of the third sheet panel. A second pattern of longitudinally spaced pressure cohesive elements, formed in the marginal portions on the second face of the third sheet panel, the second pattern of elements is staggered with respect to the first pattern of elements, such that substantial coping is avoided or distortion of the sheet in the third panel. And, other pressure cohesive patterns formed in the marginal portions of the first face of the first and second panels to cooperate respectively with the second and first patterns, to seal the longitudinal edges of the envelope for correspondence that is formed when folding in C the sheet with respect to the first and second fold lines. The other pressure cohesive patterns set forth above, preferably include a third panel of longitudinally spaced pressure cohesive elements that are formed in the marginal portions of the first face of the second panel, the third and first pattern elements of approximately the same size and shape and longitudinally spaced approximately the same distance from each other, and in the second fold line in such a way that they align and engage when the sheet is folded with respect to the second fold line, longitudinally spaced pressure cohesive elements that are form in the marginal portions of the first face of the second panel, the third and first pattern elements of approximately the same size and shape and longitudinally spaced approximately the same distance from each other and the second fold line in such a way as to align and Attach when the sheet is folded with respect to the second fold line.

While the first to fourth pattern elements may have a wide variety of configurations, such as points or circular or non-circular or various polygonal configurations, they are preferably square. A particularly convenient sizing of these square elements for conventionally sized sheets of 8.5"x 11" (or A4 size sheets) is approximately .3175 to .635 cm (1/8 x 1/4") . These cohesive elements are also separated approximately 1.27 cm (1/2") in most areas, typically spaced a distance of between approximately 1 and 3 times (eg, spaced approximately .635 to 1.9 cm (.25 to .75). ")) more than its maximum longitudinal dimension. The intermediate according to the invention may also comprise a fifth pressure cohesive pattern that is formed on the first side adjacent to the first end edge, and a sixth pressure cohesive pattern formed on the second side of the third adjacent and parallel panel to the second fold line, the fifth and sixth cohesive patterns formed on the second face of the third panel adjacent and parallel to the second fold line, and the fifth and sixth cohesive patterns positioned so that they align and mate with each other when the sheet is folded in C with respect to the first and second fold lines.

DETAILED DESCRIPTION OF THE DRAWINGS An intermediary for an envelope-type business form for sending C-shaped correspondence in accordance with the present invention is illustrated in Figures 1 to 4. The intermediary comprises a sheet of paper 10 having first and second opposite parallel end edges 11, 12, first and second opposite parallel longitudinal edges 13, 14 (preferably substantially transverse to edges 11, 12) and first and second faces 15, 16. First face 15 is adapted to provide most of the inside of an envelope for mailing correspondence (see Figure 5) constructed using the sheet 10, while the second side 16 is adapted to provide the majority of the outside of the envelope for mailing when it is constructed (typically all the outside) . The sheet 10 also has first and second transverse fold lines 17, 18 parallel to the end edges 11, 12. The fold lines 17, 18 can be notched lines, lines of weakness (such as lines of perforations) or any Another conventional construction that facilitates a precise folding. The sheet 10 can be formed from a wide variety of different types and weights (such as conventional bond or paper with various amounts of post-consumer recycle content) of paper. The sheet 10 can optionally provide strips 20 (see Figure 1) of pressure cohesive on the edge 11 adapted to cooperate with strips 21 (see Figure 2) on the face 16 adjacent to the second fold line 18. The pressure cohesive for the strips 20, 21 - and for all the cohesive pressure patterns and elements hereinafter referred to - preferably of the type used for conventional SPEEDISEALME Moore mailing envelopes and described in detail in the US patent No. 5,201,464 (the description of which is incorporated herein by reference) or the other pressure cohesives described in said patent. The sheet 10 may also comprise optional longitudinal weakening lines 22, 23, parallel to and adjacent though spaced apart from the second fold line 18, and the cohesive strips 24, 25 that are formed on the first face 15 between the weakening lines 24. , 25 and on opposite sides of the fold line 18, the strips 24, 25 cooperate with each other when the sheet 10 is bent at C with respect to the fold line 18 and the strips 25 are staggered with respect to the strips 21, so that they are not in exactly opposite portions of sheet 10 (compare Figures 1 and 2). The sheet 10 also comprises first and second longitudinal weakening lines 26, 27, parallel to and adjacent though transversely spaced from the longitudinal edges 13, 14, respectively, the weakening lines 26, 27 define: with the longitudinal edges 13, 14 - longitudinal marginal portions 29, 30. The weakening lines 26, 27 are preferably lines of perforations but may comprise any conventional weakening lines. The sheet 10 also preferably comprises the optional transverse weakening line 28 which is parallel to and adjacent to but spaced from the edge 11 on the opposite side of the edge 11 from the strips 20. Signals 32 can be formed in image where indicated in both of the faces 15, 16, the signals 32 are either non-variable signals that can be imaged commonly in all produced sheets 10 or non-variable signals in conjunction with variable signals formed in image by a laser printer or the like through which the sheet 10 is passed is passed during production of an envelope for mailing. If the laser printer is a simple printer, the signals 32 will typically be imaged only on the face 15, whereas if it is a duplex printer, variable signals 32 can be imaged on the face 16 as indicated in Figure 2.

As seen in Figures 2 and 3, the fold lines 17, 18 divide the sheet 10 into first, second and third panels 34-36, respectively, the first panel between the edge 11 and the first fold line 17, the second panel 35 between the fold lines 17 , 18, and the third panel 36 between the second fold line 18 and the second end edge 12. What has hitherto been described is basically conventional in SPEEDISEALMK intermediaries with C-fold to produce envelopes for mailing with crease C. In accordance with the present invention, particular pressure cohesive elements are provided in the marginal portions 29, 30, which have the advantages of substantially eliminating cupping or distortion of the sheet 10, in order to improve the processing of the sheet 10. through laser cutting sheets and post-processing equipment, while allowing easier stacking of sheets 10 during fabrication, while still providing an adequate seal on the envelope for sending correspondence produced. In accordance with the present invention, a first pattern of longitudinally spaced pressure cohesive elements 38 (see Figure 1) are formed in the marginal portions 29, 30 on the first face 15 of the third panel 36. The elements 38 are longitudinally spaced apart preferably a substantially uniform distance 39. The sheet 10 also includes a second pattern of longitudinally spaced pressure cohesive elements 40 (see Figure 2) formed in the marginal portions 29, 30 on the second face 16 of the third panel of the sheet 36, the elements 40 are spaced apart longitudinally from each other by a substantially uniform distance 41. As seen more readily in Figure 3, the elements 40 are staggered with respect to the elements 38, such that the sheet 10 has no cohesive in the same part of the sheet on opposite sides, in such a way that substantially cooping or distortion of the sheet 10 is prevented in the third panel 36. The sheet 10 t it also includes other pressure cohesive patterns formed in the marginal portions 29, 30 of the first face 15 of the first and second panels 34, 35, to cooperate respectively with the second and first panel elements 40, 38 respectively, to seal the edges longitudinals 13, 14 of the mailing envelope (see Figure 5) formed by folding in C, the sheet 10 with respect to the fold lines 17, 18. These other patterns may comprise strips in a wide variety of other configurations, but Preference - as illustrated in Figure 1 - includes a third pattern of longitudinally spaced pressure cohesive elements 42 formed in the marginal portions 29, 30 of the second panel 35, first face 15, the elements 42 are longitudinally spaced apart by a distance 43 The elements 42 and the spacings 43 are of approximately the same size and shape and dimension as the elements 38 and their spacings 39, such that the 38, 42 align and engage when the sheet 10 is folded with respect to the second fold line 18. The other patterns also preferably include a fourth pattern of longitudinally spaced pressure cohesive elements 44, formed at the marginal positions 29, 30 of the first panel 34, first face 15. The fourth pattern elements 44 are approximately the same size and shape as the second pattern elements 40, and the spacings 45, 41 are substantially the same, such that the elements 40, 41 align and coupled when the sheet 10 is folded at C with respect to the fold lines 17, 18 as schematically illustrated in Figure 4. While the elements 38, 40, 42, 44 can have a wide variety of configurations including circular dots, non-circular points, elements of polygonal shape and the like, or even irregular shapes, preferably square in configuration (either square or rectangular, preferably rencia rectangular) as illustrated in the drawing, and have a maximum longitudinal dimension, this maximum longitudinal dimension is typically greater than its transverse dimension. For example, for the elements 38, 40, 42, 44 illustrated in the drawings, a typical size would be approximately .3175 cm (.12") (the transverse dimension) by approximately .635 cm (.25") the longitudinal dimension) . The spacings 39, 41, 43, 45 are typically at least as large as the longitudinal dimensions of the elements 38, 40, 42 and 44. That is, the longitudinal elements 39, 41, 43, 45 are preferably between approximately 1 and 3 times larger than the maximum longitudinal dimension of the elements 38, 40, 42, 44. Preferably, they are approximately twice as long, ie approximately 1.27 cm (.5") for the preferred dimensions of the elements 38, 40 , 42, 44 described above It should also be noted that the dimensions of the elements 38, 42 may be different from the dimensions of the element 40, 44, although for ease of construction they are preferably the same.The elements 38, 40, 42 and 44 are typically applied using conventional spot coating techniques In order to provide for the proper alignment of the elements 38, 42, as seen in Figure 1, the closest elements 38, 42 to each other are spaced apart from each other. longitudinal distance 47 of the second fold line 18. As seen in Figures 1 and 2, in order to provide adequate alignment of the elements 40, 44, the elements 40 closest to the edge 12 are spaced the same longitudinal distance 49. that the closest elements 44 in the first fold line 17. It should be noted that all the elements 38, 40, 42 and 44 associated with the marginal portion 30 can have different configurations and spacings than the same elements associated with the marginal portion 29. provided that the elements within any marginal portion 29, 30 properly align. However, for ease of construction it is preferred that the elements within the margins 29, 30 be of the same size and spacing including the spacings 47, 49. As seen in Figures 2 and 5, the sheet 10 typically has directional signs. output 52 formed in image on the second side 16 of the first panel 34. These output direction signals 52 are typically variable signals formed in image by a laser printer or the like and may have either the orientation illustrated in Figures 2 and 5. , or being "upside down" with respect to what is illustrated in Figures 2 and 5. Alternatively, these exit direction signals 52 may be provided by a label that is applied on the face 16 of the first panel 34 or may printed by impact after the envelope for mailing 53 --see Figure 5 - - has been formed. In a typical use of the sheet 10, it is passed through a laser printer or the like, in such a way that at least some of the signals 32 and / or the output direction 52 are formed in image, then passed to an equipment seal with conventional SPEEDISEALMR pressure, which first doubles the sheet 10 in relation to the fold lines 17, 18 as illustrated in Figure 4, and then seals the cohesive strips and elements 20, 21, 24, 25, 38, 40, 42 and 44, typically by applying pressure only in alignment with the strips or cohesive elements and not over the entire width and length of the shape. The envelope for mailing 53 thus produced has the same three panels 34-36 as sheet 10, only they are re-arranged. That is, the mailing envelope 53 has a top panel formed by the first panel 34, with top and bottom faces, the top face formed by the face 16 of the panel 34 of the intermediary, and the bottom face formed by the face 15 of panel 34 of the intermediary. The mailing envelope 53 has a middle panel 36 which was the third panel of the intermediary, which has an upper face which was the face 16 of the intermediary panel 36, and a bottom face which was the face 15 of the intermediate panel 36. The upper face of the middle panel is parallel and adjacent to the bottom face of the top panel. The mailing envelope 53 further comprises a bottom panel, which was the second panel 35 of an intermediary. The upper face of the bottom panel 35 is the first face 15 of what was the intermediary, while the bottom face of the panel 35 is the face 16 of what was the intermediary. The upper face of the bottom panel is parallel to and adjacent to the bottom face of the middle panel. The middle panel 36 also has parallel end edges that connect to the top and bottom panels, 34, 35. These connections are what the fold lines 17, 18 of the intermediary were. In the envelope for sending correspondence 53, the weakening lines 22, 23 and 28 (if these weakening lines are provided) are in alignment with each other, as are the weakening lines 26, 27 and the various panels 34-36. To open the envelope to send correspondence 53, first is torn on the weakening lines 26, 27, to separate the marginal portions 29, 30, and then - if provided - on the weakening lines 22, 23, 28 for provide two sheets of paper, one is that portion of the intermediate panel bordered by the lines 23, 26 and 27 and the edge 12 and the other is that part of the panels 34, 35 bordered by the lines 22, and 26 to 28. While that the simple construction illustrated in the drawings is preferred, the intermediate with fold or with C-fold and envelope for sending correspondence according to the present invention may also have an arrangement for inserts shaping the envelope for sending correspondence as illustrated in Figure 4, and can also provide cohesive strips to form a return envelope, as described in the US patent No. 5,201,464 [ie, different cohesive strips or other patterns and different weakening lines are provided than those described above with respect to the optional strips or lines 20, a 25 and 28]. While the invention has been described here and illustrated in what is currently conceived as the most practical and preferred embodiment, it will be apparent to those of ordinary skill in the art that many modifications can be practiced within the scope of the invention, to this extent The broadest interpretation of the appended claims must be granted to cover all structures and products and equivalents.

This improves the processing of the intermediary through laser printers of cut sheets and post-processing equipment and allows easier stacking during manufacturing. A paper hole (10) having first and second sides and longitudinal edges parallel and opposite, has first and second transverse crease lines (17, 18) that form a sheet in three panels (34-36), and first and second longitudinal lines of weakness (26, 27) that form longitudinal marginal portions with the longitudinal edges. A first pattern (38) (such as spaced square cohesive elements) is formed in the marginal portions of the first face of the third panel while a second pattern of pressure cohesive elements (40) is formed in the second face of the marginal portions. of the third panel, the second pattern of elements staggered with respect to the first pattern, in such a way that substantial anchoring or distortion of the sheet in the third panel is avoided. Other pressure cohesive patterns formed in the marginal portions cooperate with the first and second panels, to seal the longitudinal edges of the envelope for mailing, the other patterns typically also comprise spaced square cohesive elements. An envelope for sending correspondence is formed from the intermediary by folding the sheet in C with respect to the first and second fold lines.
