Business form

A new business form having integral therewith a mailing envelope, a customer statement, and a return envelope. The new business form includes an outer sheet having a releasable bisecting center line dividing the outer sheet into and forming thereby a first side and a second side, and an inner sheet which is secured to the first side along three edges thereof to form the return envelope. The second side is adapted to receive customer information and function as the customer statement. The outer sheet is folded on the bisecting center line and releasably attached along the outer edges of mating surfaces of the first side and the second side to form the mailing envelope. The improved business form may be one of a continuous series of improved business forms which are adapted for use on high speed data processing equipment.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
This invention relates to a new and unique business form which includes a 
mailing envelope, a customer statement and return envelope. Business forms 
of this type are generally used for business correspondence where a return 
mailing, such as payment, is anticipated. Frequently, where high volume 
mailings are required, such business forms are manufactured in a 
continuous series for statement preparation on data processing equipment. 
2. Brief description of the Prior Art 
Conventional business forms generally included a separate mailing envelope, 
separate insert material, separate customer statement, and when required, 
a separate return envelope. Frequently, such materials are individually 
prepared, with possibly the customer statement being prepared on data 
processing equipment, and usually individually inserted into the mailing 
envelope for distribution to the customer. Recently, with the advent of 
data processing equipment, forms have been developed which are adapted for 
automatic preparation. 
U.S. Pat. No. 3,339,827 disclosed a business form which includes a 
pre-sealed mailing envelope and enclosed business records. Similarly, U.S. 
Pat. No. 3,608,816 disclosed a series of detachable envelopes, suitable 
for data processing equipment, each of which include an envelope and 
insert material. While both of these patents disclose fabricated business 
forms which are suitable for preparation on data processing equipment, 
they require multiple layers of pre-printed sheets to form mailing 
envelopes and customer statements. Further, because the mailing envelopes 
are pre-sealed, the only method by which the customer statement 
information can be imparted to the customer statement is through some form 
of impact printing technique, such as carbon backing on the under side of 
an interior sheet which transmits the customer information to the customer 
statement sheet when run through conventional printers. Additionally, 
neither of these patents disclose a device which provides an integral 
return envelope. 
U.S. Pat. No. 3,507,519 discloses a business form which includes a mailing 
envelope, a return envelope and a customer statement which has a customer 
stub and return stub. This form consists of two sheets, in full registry, 
which are secured along the outer edges of the mating surfaces of their 
opposing sides. An array of gluing lines and tear perforations provide the 
customer statement and return envelope. Customer statement information is 
imparted to the statement through impact printing such as a transfer 
carbon on an interior sheet. 
The form disclosed in U.S. Pat. No. 3,507,519 requires the top and bottom 
sheets to be secured (glued) along their side edges then transversely 
folded along a center tear perforation line to form the mailing envelope. 
Inherent to this form is a problem commonly referred to as tenting. 
Tenting occurs where a fold is applied along a line which separates 
securing means (such as gluing) on either side of the fold line. The 
tenting problem, a bulge in bottom sheet, results from the different 
length taken by the top and bottom sheets during the fold operation and 
the inability of the two sheets to adjust to this difference in length. 
Further, there is no provision for direct printing of the statement 
information, which frequently results in illegible or obscure statement 
information. A further disadvantage of the aforesaid form is that the 
transversely oriented cross tear perforation line on which the form is 
transversely folded to form the mailing envelope is susceptible to 
separation during the bursting operation separating the individual forms. 
SUMMARY OF THE INVENTION 
The present invention relates to an improved business form having therein a 
mailing envelope, a customer statement, and return envelope. The improved 
business form includes an outer sheet with a 
longitudinal-releasable-bisecting center line dividing said outer sheet 
into and forming thereby a first side and a second side. The second side 
is adapted to accept direct printing of statement information to form the 
customer statement. An inner sheet is attached to the first side of the 
outer sheet and secured along three edges thereof to form the return 
envelope. The outer sheet with attached inner sheet is longitudinally 
folded along the center line with the outer edges of the mating surfaces 
of the first side and the second side being releasably secured to form the 
mailing envelope. 
The improved business form may be constructed in a series of individual 
forms for statement preparation on data processing equipment. In such an 
embodiment, the outer sheet and attached inner sheet are provided with 
transverse tear perforations or lines of weakening which allow the 
separation of the individual forms. The first side of said outer sheet may 
be provided with a sending die-cut opening whereby the customer name and 
address, which is part of the customer statement information provided on 
the customer statement, is visible through said sending opening of the 
folded mailing envelope. 
Upon receipt of the improved business form, the customer separates the 
first side from the second side, examines the statement information, and 
returns appropriate material, such as a payment, in the pre-addressed 
return envelope. 
An embodiment of this invention provides a copy statement by means of an 
enlarged inner sheet which is adapted to customer requirements of size, 
shape, paper or print. The enlarged inner sheet, extending beyond the 
bisecting center line, covers the second side, and is secured to the first 
side in the manner rquired to form the return envelope. The enlarged inner 
sheet further includes, in approximate registry with the bisecting center 
line, a longitudinal-releasable-line which allows for the separation of 
the copy statement. 
It is an object of this invention to provide an improved business form 
which includes an integral mailing envelope, a customer statement, and 
return envelope. A further object of this invention is to provide an 
improved business form which allows for the direct printing of statement 
information. It is a further object of this invention to provide an 
improved business form which avoids the tinting phenomenom associated with 
a folded form. A further object of this invention is to provide an 
improved business form with integral mailing envelope, customer statement, 
and return envelope which can be economically produced and easily used, 
and which can accommodate special size, shape and print requirements for 
the customer statement. A further object of this invention is to provide 
an improved business form with integral mailing envelope, customer 
statement, which is adapted for direct printing of statement information, 
and return envelope constructed of a single inner sheet. A further object 
of this invention is to provide an improved business form which is adapted 
for preparation on automatic data processing equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, the preferred embodiment of my invention is an 
improved business form 10 which includes a mailing envelope 11, a customer 
statement 12 and a return envelope 13. The improved business form 10 is 
manufactured in a continuous series 5 of individual business forms 10, 
each individual business form 10 being delimited by transverse lines of 
weakening 15. 
The improved business form 10 is comprised of an outer sheet 21 having a 
longitudinal bisecting center line of weakening 22 whereby a first side 23 
and a second side 24 are formed. The bisecting center line 22 is 
continuous through the entire continuous series 5 of individual business 
forms 10. The second side 24 is adapted to receive direct printing of 
customer information 25 in an appropriate format whereby to form the 
customer statement 12. The second side 24 is further provided with a 
statement line of weakening 26 which delimits a customer stub 27 from a 
return stub 28. 
The improved business form 10 further includes a longitudinally oriented 
inner sheet 30 which is continuous through the entire continuous series 5 
of individual business forms 10, and whereby the lines of weakening 15 
extends through said inner sheet 30. The inner sheet 30, confined to the 
first side 23 of the outer sheet 21, extends from the top edge 31 of the 
improved business form 10 to the bottom edge 33. The inner sheet 30 has 
the center edge 32 which is parallel to and adjacent to the bisecting 
center line 22, and is adhesively secured to the outer sheet 21 along the 
top edge 31, center edge 32, and bottom edge 33, leaving the remaining 
edge 37 open and forming a pocket 34 between the inner sheet 30 and the 
outer sheet 21. 
An alternative orientation of the inner sheet 30 is shown in FIG. 2 whereby 
the inner sheet 30 extends from the top edge 31 to the bottom edge 33 and 
whereby the inner sheet 30 has one edge parallel to and adjacent to the 
outer edge 32A of the first side 23. The inner sheet 30 is secured to the 
outer sheet 31, outer edge 32A and bottom edge 33 leaving the inner edge 
37A open to form a pocket 34 between the inner sheet 30 and the outer 
sheet 21. 
Referring back to FIG. 1, the first side is further provided with a return 
envelope sealing flap 40. The sealing flap includes a longitudinally 
oriented return line of weakening 36 which is parallel to and which is 
positioned outside the remaining edge 37 of the inner sheet 21, a 
longitudinally oriented score line 38 which is parallel to and which is 
positioned at the remaining edge 37, and a return adhesive strip 39 which 
is positioned intermediate the score line 38 and the return line of 
weakening 36. The adhesive material considered best for the strip 39 is a 
remoist glue manufactured by Stein Hall and known as Flash Seal. 
The outer sheet 21 is further provided with a first feed strip 41 (see FIG. 
3) and a second feed strip 42 (see FIG. 4). Both the first feed strips 41 
and the second feed strips 42 are continuous through the continuous series 
5 of improved forms 10. Both feed strips have strip lines of weakening 43 
and a plurality of feed holes 44 adapted for operation with data 
processing equipment. 
The outer sheet is provided with a mailing adhesive strip 46, positioned 
within the second feed strip 42, and a plurality of releasable adhesive 
spots 47, evenly distributed along the upper edge 51 and lower edge 52 of 
the second side 24 of the outer sheet 21. The adhesive material considered 
best for the mailing adhesive strip 46 and spots 47 is a reheat glue 
manufactured by Swift and known as #2518. 
Rather than the adhesive spots 47, the outer sheet 21 may be provided with 
an upper and lower adhesive strip (not shown) which includes an upper and 
lower line of weakening (not shown), and an adhesive material (not shown) 
positioned within the upper and lower strips. 
As is shown in FIG. 14, the continuous series 5 of individual business 
forms 10, having been prepared by appropriate data processing equipment is 
longitudinally folded along the bisecting center line 22 such that the 
feed holes 44 of the first feed strip 41 align with the feed holes 44 of 
the second feed strip 42. The folded continuous series 5 is fed by 
advancing means 57 through an adhesive activator 58. The adhesive 
activator 58 heats the business form 10 to activate the reheat glue of the 
mailing adhesive strip 46 and spots 47 to seal the mailing envelope 11. A 
device which is suitable for this operation is manufactured by Moore 
Business Forms, Inc. and known as the Model 812 Speedisealer. 
Each of the individual business forms 10 in the sealed continuous series 5 
of individual business forms 10 is separated at the lines of weakening 15 
through conventional bursting means forming thereby the separate 
individual business forms 10. 
FIG. 5 shows an individual business form 10 which is ready for mailing. The 
business form 10 includes a preprinted postal stamp 60, and a return 
address 61; alternatively, the return address and postal stamp may be 
applied by other means such as secondary die-cut openings, manual 
stamping, gum labels or remoist stamps. 
As shown in FIG. 5 and FIG. 1, the first side 23 of the outer sheet 21 is 
further provided with a sending die-cut opening 50 which pemits viewing of 
the customer address, part of the formatted customer information 25, which 
is in register with the sending opening 50 when the outer sheet 21 is 
folded. Other versions of this embodiment include a cellophane cover (not 
shown) disposed over the sending opening 50 to better protect the contents 
of the mailing envelope 11. Still other versions may have no opening, 
requiring that the customer address be applied by other means, such as 
manually or by applying a gum type label. 
FIGS. 6 through 9 show the sequence of use, for the improved business form 
10. In FIG. 6, the sealed first feed strip 41 and second feed strip 42 are 
detached at the coincident strip lines of weakening 43. The second side 24 
and the first side 23 are then pulled apart breaking the releasable 
adhesive spot 47 and revealing the inside of the business form 10. If 
upper and lower adhesive strips (not shown) are used in place of the 
adhesive spots 47, the upper and lower adhesive strips are detached at the 
upper and lower lines of weakening (not shown). 
FIG. 7 shows the orientation of the various components of the opened 
improved business form 10. Specifically the customer stub 27 and the 
return stub 28 of the customer statement 12 are shown as is the return 
envelope 13 with its sealing flap 40. FIG. 7 also shows the orientation of 
the sending die-cut opening 50 and a return die-cut opening 66. 
FIG. 8 shows the first side 23 being separated from the second side along 
bisecting center line of weakening 22. The second side 24 is further 
separated along statement line of weakening 26 to form the customer stub 
27 and the return stub 28. The first side 23 is divided along return line 
of weakening 36 to form the return envelope 13 with sealing flap 40 and a 
remaining portion 68. 
FIG. 9 shows the return stub 28 being inserted into the return envelope 13 
for return mailing. The return envelope 13 sealed with sealing flap 40 is 
provided with a preprinted return postal stamp 67. The return envelope 13 
is also provided with a return die-cut opening 66 which permits viewing of 
the return address, part of the formatted customer information 25, which 
is in register with the return opening 66 when the return stub 28 is 
properly inserted. Other versions of this embodiment include a cellophane 
cover (not shown) over the return opening 66 to protect the contents of 
the return envelope 13. Alternatively, the return opening 66 may be 
omitted requiring the return address to be preprinted, or be applied by 
other means such as manually or a gum type label. Similarly, the return 
postal stamp 67 may be applied by other manual means. 
FIG. 10 shows an alternate embodiment of the improved buisness form, the 
improved copy business form 70, which includes a mailing envelope 11, a 
customer statement 71, a return envelope 72, and a copy statement 73. 
Similar to the improved business form 10 shown in FIG. 1, the improved 
copy business form 70 is manufactured in continuous series of individual 
copy business forms 70, each of which is delimited by transverse lines of 
weakening 15. The improved copy business form 70 is comprised of an outer 
sheet 74 having a bisecting center line of weakening 79 forming a first 
side 78, and a second side 85, which is substantially the same as the 
outer sheet 21 of the improved business form shown in FIG. 1. 
The improved copy business form 70 also includes an inner sheet 75 which 
has a return envelope line of weakening 76 separating the return envelope 
portion 77 and copy statement 73. The return envelope portion 77 is 
adhesively secured to the first side 78 of the outer sheet 74 such that 
the return envelope line of weakening 76 is parallel to and offset 
slightly in the direction of the first side of the bisecting center line 
79 of the outer sheet 74. The return portion 77 is adhesively secured 
along the return top edge 80, the return bottom edge 81 and the first side 
edge 82 of the return envelope line of weakening 76. 
The copy statement 73 extends from the return envelope line of weakening 76 
across the bisecting center line 79 to the second feed strip 84 such that 
the copy statement is substantially in register with the second side 85. 
No portion of the copy statement 73 is secured to the second side 85 prior 
to its subsequent folding. 
The copy statement 73 includes a copy feed strip 86, also shown in FIG. 11, 
having a plurality of elongated feed holes 87 and a copy strip line of 
weakening 88. The elongated feed holes 87 are aligned with the feed holes 
89 in the second feed strip 84 and are elongated to retain this alignment 
after the outer sheet 74 is subsequently folded. The elongation is 
required because of the shorter distance taken by the inner sheet 75 than 
that of the outer sheet 74 during the folding of the outer sheet 74. The 
copy strip line of weakening 88 is positioned so that it is aligned with 
the strip line of weakening 90 of second feed strip 84 after the outer 
sheet 74 has been folded. 
Returning to FIG. 10, the copy strip 86 is provided with sealing adhesive 
strips 91 located on either side of the outer edge of the copy strip 86. 
Further, the copy statement 73 is provided with a plurality of sealing 
adhesive spots 92 located on either side of the upper edge and lower edge 
of the copy statement 73. An appropriate adhesive material is the reheat 
glue described above. 
The inner sheet 75 may be of any suitable material and the copy statement 
73 may be specially pre-cut to any shape in order that specific user 
requirements are satisfied. The customer information 95 is directly 
printed on the copy statement 73 and transferred to the customer statement 
71 through an impact printing transfer means such as carbon backing on the 
copy statement 73 or through a carbonless printing technique. 
The use and operation of the improved copy business form 70 is 
substantially the same as that of the improved business form 10 shown in 
FIG. 1. There are analogous provisions for a sealing flap, sending die-cut 
opening, and return die-cut openings. Also, the folding and sealing 
operations are analogous. The manner in which the sealed mailing envelope 
11 of the improved copy business form 70 is opened is similar. The copy 
statement 73 is detached after the mailing envelope is opened at return 
envelope line of weakening 76. 
FIG. 12 shows a third alternate embodiment of the improved business form, a 
single sheet business form 110. In this embodiment the single sheet 
business form 110 is comprised of an oversized outer sheet 111 which is 
prefolded such that a fold portion 114 overlaps and is adhesively secured 
to form a return envelope 112. Specifically, the fold portion 114 is 
adhesively secured along the fold edge 115 and along the top edge 116 and 
bottom edge 117 leaving the inside edge 118 open to form a pocket 119 
therein. The oversized outer sheet 111 is prepared with punched holes 120 
and lines of weakening 121 such that after the fold portion 114 is folded 
and secured, a first feed strip 122 has aligned feed holes 120 and aligned 
first edge strip lines of weakening 121. In every other aspect, the 
structure, operation, and use of the single sheet business form 110 is 
substantially the same as that of the improved business form 10 shown in 
FIG. 1. 
FIG. 13 shows a fourth alternate embodiment of the improved business form, 
the cross oriented business form 130, having a transversely oriented 
return envelope 131. The cross oriented business form 130, including the 
mailing envelope 133, the customer statement 132, and the return envelope 
131, is manufactured in a continuous series of such cross oriented 
business forms 130. Each cross oriented business form 130 is delimited by 
transverse lines of weakening 180 to allow preparation on conventional 
data processing equipment. 
The cross oriented business form 130 comprise an outer sheet 135 having a 
bisecting center line of weakening 137 extending from the top edge 138 to 
the bottom edge 139 whereby to form a first side 141 and a second side 
142. The second side 142 of the cross oriented business form 130 is 
similar in structure and operation to the second side 24 of the improved 
business form 10 shown in FIG. 1. 
The cross oriented business form 130 also includes an inner sheet 144 which 
is continuous through the continuous series of cross oriented business 
forms 130. The inner sheet 144 includes a pocket portion 145 and two trail 
portions 146 which connect sequential pocket portions 145 at the edges 
thereof. The inner sheet 144 is secured to the first side 141 of the outer 
sheet 135 such that the pocket portion is aligned with the bottom edge 139 
of the first side 141 with the trail portions 146 extending up along the 
outside edge 181 of the first side and along the first side edge 182 of 
the bisecting center line 137. The inner sheet 144 is glued to the outer 
sheet 135 along the bottom edge 139, and up the outer edge 181 and the 
first side edge 182 forming the transversely oriented return envelope 131 
with its opening at the upper edge 147 of the pocket portion 145. 
Alternatively, the pocket portion 145 may be secured along the upper edge 
138 of the first side 141 having the trail portion 146 extending downward, 
with the lower edge of the pocket portion being open and thereby forming 
the return envelope 131. Further, depending upon customer needs, the 
pocket portion 145 may be positioned at any point up or down the first 
side 141 of the outer sheet 135. 
Features similar to those shown in FIG. 10 may be provided whereby the 
cross oriented business form 130 would include an additional copy 
statement. The only limitation is that no glue or method of securing 
extend across the bisecting center line 137 where the cross oriented 
business form is subsequently folded to form the mailing envelope 133. The 
first side 141 is also provided with transversely oriented score lines 
148, return line of weakening 149, and return adhesive strip line 150, to 
form a sealing flap 151 for the transversely oriented return envelope 131. 
Similar in structure to the improved business form 10 shown in FIG. 1, the 
cross oriented business form 130 may be provided with a sending die-cut 
opening 152 and a return die-cut opening 153. In every other aspect of 
structure, operation, and use, the cross oriented business form 130 is 
analogous to that of the improved business form 10 shown in FIG. 1. 
FIG. 15 shows the basic structure of a continuous series of improved 
business forms 10 with a continuous series of supplemental business forms 
170 being interleaved and inserted between the first and second sides, 23 
and 24, respectively, of the mailing envelope 11 of the improved business 
form 10. 
The continuous series of supplemental forms 170 includes a plurality of 
transverse lines of separation 172 which delimits each supplemental form 
171. The supplemental form 171 is adapted to receive statement 
information, advertising information, or other forms of prepared customer 
information. The supplemental form 171 size, shape, paper, and print may 
be uniquely adapted to user requirements. 
The embodiment shown in FIG. 15 represents a plane single sheet series of 
supplemental forms 170. Alternative embodiments include a folded sheet 
series of supplemental forms (not shown) having a longitudinal fold line 
or line of weakening and multiple ply series of supplemental forms (not 
shown) which are inserted into the mailing envelope 11 during the folding 
and sealing operation. The series of supplemental forms 170 may be 
pre-die-cut to any shape and specifically to a shape which permits the 
customer name and address information 25 on the second side 24 of the 
improved business form 10 to be visible through the sending die-cut 
opening 50 of the folded mailing envelope. 
The series of supplemental forms 170 includes a supplemental feed strip 175 
having a plurality of feed holes 176 and a supplemental strip line of 
weakening 177 which are in register with the first feed strip 41 and the 
second feed strip 42, the feed holes 44 and the strip line of weakening 
43, respectively, when the series of supplemental forms 170 is interleaved 
and inserted into the folded mailing envelope 11. Each supplemental forms 
171 is further provided with an adhesive (not shown), such as the reheat 
glue described above, along both sides of the supplemental feed strip 175. 
Further, each of the supplemental forms 171 is provided with a plurality 
of supplemental adhesive spots, (not shown) which are evenly distributed 
along both sides of the top and bottom edges of the supplemental form 171. 
In practice the prepared continuous series of supplemental forms 170 are 
simultaneously fed into the advancing means 57 and adhesive activator 58 
so that the transverse lines of separation of 172 of supplemental forms 
170 are in register with the transverse lines of weakening 15 in the 
improved business form 10. The adhesive is activated by adhesive activator 
58 and individual improved business form 10 with incorporated supplemental 
form 171 are separated by conventional bursing means (not shown). 
The adhesive on both sides of the supplemental form 171 provide a means for 
substantially sealing the mailing envelope 11. The sealed mailing envelope 
11 is opened in the conventional manner by separating the secured first 
feed strip 41, second feed strip, (not shown), and supplemental feed strip 
175 at their respective lines of weakening, then by pulling the first side 
23, second side 24, and supplemental form 171 apart by breaking the 
respective adhesive spots. 
FIG. 16 shows an opened improved business form 10 having an inserted 
supplemental forms 184. The improved business form 10 includes a return 
envelope 185 positioned on the outer edge of the first side 23 of the 
outer sheet 21. This embodiment further shows the return die-cut opening 
186 as being positioned on the outer sheet 21 of the improved business 
form 10 and not on the inner sheet 30 as shown in the figures above. 
The supplemental form 184 includes an appropriate pre-die-cut opening to 
allow the customer name and address 25 within the customer statement 
information on the second side 24 to be visible through send-die-cut 
opening 50 of the folded business form 10. 
FIG. 17 shows an embodiment of an improved statement business form 190 
including a customer statement 191, a mailing envelope 192, and a 
supplemental form 193. This embodiment is intended for those applications 
of the improved business form 190 which do not require a return mailing 
and therefore does not provide a return envelope. The structure of the 
improved statement business form 190 is analagous to that of the improved 
business form 10 shown in FIG. 1. 
The improved statement business form 190 includes a continuous outer sheet 
195 having a bisecting center line 196 which forms a first side 197 and a 
second side 198. Second side 198 is adapted to receive customer statement 
information 201 or other customer information whereby to form the customer 
statement 191. The first side includes a sending die-cut opening 202. 
Similar to the process shown in FIG. 15, the supplemental form 193 may be 
interleaved between the first side 197 and the second side 198 of the 
folded outer sheet 195 as the mailing envelope 192 is being prepared. The 
supplemental form 193 includes a supplemental feed strip 203 which is in 
register with the first feed strip 204 and the second feed strip 205 on 
the first side 197 and second side 198, respectively, of the folded 
mailing envelope 192. The supplemental form 193 is further provided with 
an appropriate adhesive 207 on both sides of the outer edges of the 
supplemental form 193 to provide a means for releasably securing the 
folded mailing envelope 192. The supplemental form 193 is adapted to 
receive statement information 206 or other customer information so that 
the customer name and address 208 which may be applied to the supplemental 
form 193 is visible through the sending die-cut opening 202 of the folded 
mailing envelope 192 when the supplemental form 193 is inserted. 
Alternatively, the supplemental form 193 may be pre-die-cut or may be 
omitted to allow the customer name and address within the customer 
statement information 201 on the second side 198 to be visible through the 
sending die-cut opening 202 of the folded mailing envelope 192. 
Generally with regard to the structure of my invention a plurality of copy 
statements may be included providing that no glue line or method of 
attaching extends across the bisecting center line, that line on which the 
business form is folded. Either side of my invention may be designated the 
first or second side in that my invention is independent of such a 
distinction. The outer sheet, inner sheet, and any additional copy 
statements may be pre-printed on one or both sides with standard form 
information as the user's requirements dictate. 
It is understood that the description of my invention is done to fully 
comply with the requirements of 35 USC 112 and it is not intended to limit 
my invention in any way. It can be seen from the above description that 
variant forms of the improved business form can easily be developed. 
Therefore, such variant forms are considered to be within the scope and 
essence of this invention.
