~ Technical field :;.
~: .
~ The present invention relates to a postcard and a ~`
.~ . .
manufacturing method thereof, more specifically, the present
invention relates to a postcard for covering temporarily a
,
portion provided with a confidential matter formed on a
surface of a postcard material by adhering it on the portion,
and a manufacturing method thereof.
Background Art
As a conventional postcard which constitutes a
background of this invention, there is a material including a~
postcard material formed a confidential matter on a surface
thereof, and a sticking material which a pressure sensitive
adhesive layer is formed on the reverse side of postcard ::
material . ` . ,~
In this conventional postcard, a surface of a postcard
material can be covered by adhering it on the surface of :~
the postcard material, however, it is not preferably used for ;~.
covering temporarily the confidential matter, since the ` :~
sticking material is hardly peeled off from the surface of ; ~;
- .: '
"~' :
;~ ''`''
2~2~67
the postcard material.
In oxder to facilitate peeliny the stickin~ material
from the surface of the postcard material, it is thin]iing
that a peeling process such as silicon processing is applied
on the surface of the postcard material so as to be peeled
off the sticking material. However, an applying the peeling
process on the postcard material complicates a machinery, and
the cost for manufacturing increases. Therefore, it is
har~ly to apply the pee~ng process. And, further, if
peeliny process is applied on the surface of the -~ostcarcl
material, the sticking material is separated from the
postcard material inadvertently.

Furtller, on the surface of the postcard material 12, a
lottery part 13a such as a letter "winning': or "lose" and a
confidential matter 13b such as a information of the finance
or the insurance are forrned. ~he lottery part 13a and the
confidential matter 13b are formed by printing on the surface
of the postcard rnaterial 12. Meanwhile, the lottery part 13a
and the confidential matter 13b ~nay be formed by writing with
a pen.
On the surface of the postcard material 12 including the
lottery part 13a and the confidential matter 13b, the
covering material 14 is adhered.
Next, the covering material 14 will be explained in
refer to Fig. 2, Fig-. 3A and Fig. 3B principally.
The covering material 14 includes a sheet of base
material 18, the base material 18 is formed with a relatively
soft material such as paper, synthetic resin fil~n and the
like which can be cut by a scissors or the like.
~ nd on one main surface of the base material 18 a
suppression layer 20 is formed.
: ,
~;The suppression layer 20 is formed by printins a silver
ink and the like or laminating a film material such as an
aluminun foil having a suppressiveness with adhesives and the
like.
On the surface of the suppression layer 20, a first heat
adherent resin layer 22 is formed by coating a heat adherent
9 :
.`
2 ~ 2 ~
resin with a weak adhesive strength as heating and extruding
it, or by gravure or silk screen printing as dissolving it in
a solvent or despersing in water and the first heat adherent
resin layer 22 has a weak adhesive strength . ~ -
The first heat adherent resin layer 22 is formed to melt
at about 100C to 200C so as to be adhered to the postcard
Material 12 made of paper or the like with a weak adhesive
strength.
As an example of said heat adherent resin having a weak
adhesive strength, adhesives of EVA group may be selected.
The composition of the adhesive cornprises an EVA (ethylene~
vinyl acetate copolymerized resin), a tackifier, a wax and an
anti-oxidant, to which sometimes a release agent such as
silicon or reducing the adhesion, a plasticizer and a filler
are added as an adjutant.
As the tackifier, there are glycerin of partially
: . ~ . ~ :
hydrogenated rosin, glycerin-ester of rosin, pentaerythritol ;
modified rosin, petroleum resin, ~ -methylstyrene/vinyl
toluene copolymer, terpene oil polymer and terpene-phenol
polymer, etc
As the wax, there are paraffin wax, microcrystalline `
wax, low molecular weight polyethylene wax, Fischer-Tropsch
wax, caster wax and chlorinated paraffin, etc. ;
As the anti-oxidant, there are hindered phenol group

~' ~;
com~ound, benzotriazol group compound, phosphorus group
compound, sulfur group compound, organic metal yroup
compound, etc.
As the heat adherent resins having a weak adhesive
strength other than the aforesaid examples, there are
stylene-butadiene-stylene copolymer, stylene-isoprele-stylene
copolymer, polyethylene, ethylene-ethylacrylate
copolymerized resin, ethylene-acrylic acid copolymerized
resin, ethylene-methyl acrylate copolyMerized resin,
ethylene-methyl methacrylate, ethylene-methacrylic acid
copolymerized resin, ionomer resin, polymethylpentene resin,
ethylene-vinylalcohol copolymerized resin, vinylidene
chloride resin, vinyl chloride-vinyl acetate copolymerized
resin, polyamide resin, stylene-acrylic acid copolymerized
resin, polystylene resin, polyacrylic acid copolymerized
resin, polyester resin, polyurethane resin, waxes, etc. When
printing and coating, these resins can be suitably used as
:
heating or dissolving in a solvent or dispersing in water.
Further, on the surface of the first heat adherent resin
layer 24, a second heat adherent resin layer 24 having a
strong adhesive strength is formed. In this embodiment , the
,:- . ~ I .
second heat adherent resin layer 24 is formed at both sides
in the lengthwise direction of the postcard material 12, that
is, in the fixed width at the upside and downside of the
covering material 14. Moreover, the second heat adherent
.
;~ .
'-~
202~867
resin layer 24 is formed at both sides in the breadthwise
direction of the postcard material 12, that is, at riyht and
left ends of the covering material 14 in spots. The second
heat adherent resin layer 24 is formed by coating a heat
adherent resin having a strong adhesive strength, for example
adhesl-v~es of EVA group, stylene-butadiene-stylene copolymer,
stylene-isoprele-stylene copolymer in parts.
In this case, for exarnple, the tac]cifier is mixed more
~ .: . . :
as compared with the heat adherent resin having a weak -
adhesive strength or the release agent is mixed less as -
compared with the heat adherent resin having a weak adhesive
strength, in the heat adherent resin having a strong adhesive
strength. The second heat adherent resin layer 24 may be
formed at only both sides of upside and downside or both ;~
right side and left side of the covering material 14. The
second heat adherent resin layer 24 may be formed in the ~
fixed width or may be formed in spots. ~ ~`
~ , . ., ~.
Next, a method of manufacturing the covering material 14
will be explained.
Flrst, a paper forming the base material 18 is prepared, `~
and the suppression layer 20 is formed on one main surface ;~
thereof by allover printing with a silver ink, for example,
by the known printing method as the offset printing or
coating.
... .
~As showing Fig. 4, a rolled laminate comprising the base ; ~`
: . :., :
12 `
''~ ,; :..
202~67
material 18 formed with the suppression layer 20 is
mounted on a hold roller 32 of a manufacturing-~achine 30 for
the covering material.
; The base material 18 held by the hold roller 32 is
loosen at one end and led to a heat adherent resin coater 34
for printing or coating the heat adherent resin 22a
containing, for example, the aforesaid ethylene~vinyl acetate
copolymerized resin as a main component. The heat adherent
resin coater 34 is a printing or coating ~nachine utilizing
known printing or coating methods such as a typographic
printing, gravure printing, silk screen printing, offset
printing or the like.
By the heat adherent resin coater 34, the heat adherent
resin 22a having a weak adhesive strlenyth is printing or
coating on the surface of the suppression layer ~0.
The base material 1~ onto which the heat adherent resin
22a is printed or coated is led to a dryer 36, whereby the
heat adherent resin 22a is clried and the first heat adherent
resin layer 22 is formed.
Next, the base materlal 18 on which the first heat
adherent resin layer 22 is formed is led to a heat adherent
~.1` i ' . :
resin coater 40 for printing or coating the heat adherent
` resin 24a having a strong adhesive strength. The heat
adherent resin coater 40 is a printing or coating machine
utiIizing known printing or coating methods such as ~
: . ~,
~ .~
2 ~ 2 9 ~
typographic printing, gravure printing, silk screen printing,
offset printing or the like. By the heat adherent resin
coater 40, the heat adherent resin 24a is printing or coatiny
on the sur~ace of the first heat adherent resin layer 22.
The base material 18 onto which the heat adherent resin
24a is printed or coated is led to a dryer 42, whereby the
heat adherent resin 24a is dried and the second heat adherent
resin layer 24 is formed.
Thus, as shown in Fi~. 5B, a continuous sheet 14a of the
covering material is formed with the base material 18, the
suppression layer 20, the first heat adherent resin layer 22
and the second heat adherent resin layer 24.
The continuous sheet 14a of the covering material is
wound round a take-up roller 44 again.
In this embodi~lent, as shown in Fig. 2 and Fig. 5B, the
suppression layer 20 is formed on one main surface of the
base material 18, and the first heat adherent resin layer 22
is formed on the surface of the suppression layer 20.
The second heat adherent resin layer 24 is forMed on a
surface of the first heat adherent resin layer 22, at the
upside and downside of the covering- material 14 in the fixed
!:, i ' i:, . :
width. Further, the second heat adherent resin layer 24 is -
`~ formed on a surface of the first heat adherent resin layer 22
at both right side and left side in spots~ Therefore, the ;
covering material 14 is adhered strongly to the postcard
2~29867
aterial 12 at a portion which the second adherent resin
layer 24 is formed and i5 adhered wea~ly to the postcard
material 12 at a portion which the second adherent resin
layer 24 is not formed.
Meanwhile, as the example of the base material 18,
besides the aforesaid example, there are films of synthetic
paper, cellophane, polyethylene, polyester, etc. or an
aluminum foil and the like. However, relatively soft
materials are preferably selected as the base material 18
such that when the covering material 14 is adhered to the
postcard material 12, it will not come off easily therefrom
against the adhesions of the first heat adherent resin layer
22 and the second heat adherent resin layer 24.
When the aluminum foil and the like having a good
suppressiveness is selected as the base material 18, the
suppression layer 20 is not necessary. In this case, the
first heat adherent resin layer 22 is formed on one principal
surface of the base material 18.
Also, on the base material 18, any suitable printing
which fits to properties of the postcard may be performed, or
when the continuous material is used as aforesaid
~ ,.. . ( I ,
embodimentsl for example, a detecting mark(arrow) for
detectiny feeding pitches of the base material 18 may be
~ printed with a black color or the like.
;~ Next, a method for adheriny the covering material 14 on
~ .
- ~ :
2~29~7
the surface of the continuous raw paper lOa will be
explained on the basis of an adhesion machine shown in Fig.
6 through Fig. 11.
The adhesion machine 100 for the covering material
comprises a continuous paper transfer unit 102 which is
designed to feed the continuous raw paper lOa shown in Fig.
5A to the position where the covering material 14 is adhered.
The continuous paper transfer unit 102 includes transfer
sprockets 106 formed substantially on opposite ends of a
adhesion machine body 104, and an adhesive portion transfer
device 108 which is formed substantially in the center of the
adhesion machine body 104 to transfer the continuous raw
paper lOa in the transferring direction by a suitable
distance which, in the present embodiment, corresponds to the
length of a sheet of covering material 14 adhered to the
postcard material 12. The transfer sprockets 106 which are
designed to rotate belts formed with projections which engage
. . .: :. .
to the sprocket holes 16 of the continuous raw paper lOa,
successively engage the projections to the sprocket holes 16
to transfer the continuous raw paper lOa.
The adhesive portion transfer device 108, as shown in
Fig. 7A, includes a continuous paper transfer cum 114 secured
to a shaft 112 disposed across the front and rear of the
adhesion machine body 104. A suitable ~roove is formed in
the body of the continuous paper transfer cum 114 which
':
~ 16 ~
''. ~'''
2~2~67
gives suitable vertical and front-to-back movements to a link
mechanism 116 by its uniform rotation. By the action of the
link mechanisra 116, an adhesive portion transfer table 118
fixed to the link mechanism 116 is moved back and forth
continuously or intermittently. That is, the linlc mechanism
116 inrludes a link 116b which is fixed rockably to the
adhesion machine body 104 with a pivot shaft 116a and a link
116c fixed rotatably to the adhesive portion transfer table
118, and the link 116b is pivotally fixed to the link 116c.
The adhesive portion trasnfer table 118 is rnove back and
forth through the link mechanisrn 116 by rotation of the
continuous paper transfer cum 114.
The amount of continuous raw paper lOa transferred in
the continuous paper transfer unit 102, as shown in Fig. 7~
is detected by a synchronizing device 119. That is, a
portion of the adhesive portion transfer table 118 is
connected to a timing belt ll9c mounted between timing
pullies ll9a and ll9b provided at the front and rear of the
adhesion machine body 104 by a connecting piece ll9d, thereby
the transferrig distance of the adhesive portion transfer
table 118 is detected by a pulse signal from an encoder ll9e
coupled to the timing pully ll9b to control the rotation of a
pulse motor which is a drive source formed on the continuous
paper transfex unit 102 for the overall control.
Next, a transfer unit of the covering material 14 which
17
2~29~6~
is adhered to the surface of the continuous raw paper lOa
fed successively by the continuous paper transfer unit 102
will be explained with reference to Fig. 8, Fig~ 9A and Fig.
9B.
The covering material transfer unit 120 includes a reel
122 wh~reon the rolled continuous sheet 14a of the covering
material continuously formed by the covering material 14 is
mounted, a covering material detector 124 which detects the
transferring amount of the continuous sheet 14a pulled out
from the reel 122 and the arrival of the continuous sheet
14a at a specified position to output the eleetrieal signal
to a controller of the covering rnaterial transfer unit 120,
and a coveringmaterial cutter 126 which is disposed on the
downstream side from the covering material detector 124 to
eut the continuous sheet 14a into a suitable length.
In the eovering material transfer unit 120, at the front
and rear of the covering material eutter 126 whieh euts the
eontinuous sheet 14a, a pair of covering material earries 128
eomprising rubber rings fixed to a shaft and rotatable as
~ ~ ~ ......
contaeting each other are disposed.
The eontinuous sheet 14a of the eovering materials
elarnped between the rings of the pair of covering material
carriers 128 is earried to the suitable position on the
sufrfaee of the eontinuous raw paper lOa by the rotation of
; the eovering rnaterial earriers 128. --~

as shown in Fig. 9B. The disc 142 is fixed to the shaft 112
which secures the continuous paper transfer cum 114.
Accordingly, as the disc 142 rotates the cutter shaft
136 is rotated by the action of cum groove formed in the
disc 142 throuyh the links 140a and 140b, thereby the cutter
blades 130a and 130b are pivoted about the pivot axes 130c
$ixed to the cutter body 132 to cut the continuous sheet l~a
!: :
of the covering material into the suitable size.

A prescribed amount of continuous raw paper lOa is
transferred by the transfer sprockets 106 of the continuous
paper tranfer unit 102.
The adhesive portion transfer table 118, in the present
embodiment, is moved from the downstreaml side to the upstream
side of the continuous raw paper lOa.
While, as the continuous sheet 14a of the covering
material is transferred from the reel 122 by the covering
material transfer unit 120, the covering material detector
124 detects a detecting mark, an arrow in this embodiment,
formed on the continuous sheet 14a of the covering material,
and by the detecting si~nal of the coverin~ material detector
124, the continuous sheet 14a is stopped temporarilly as
well as the adhesIve portion transfer table 118. At this
time, the covering material cutter 126 is actuated and the
~ ,
cutter blades 130a and 130b cut the continuous sheet 14a of -~
the covering material into a suitable size, that is, a sheet
of covering material 14 by the action of cum groove in the
~` disc 142. ;~
The front end of the covering material 14 cut into the

direction of the continuous raw paper lOa by the lineal
pressing and heatiny device 152 forming the pressing and :.
heating unit 150 to adhere primarily to the continuous raw
paper lOa.
Then, simultaneously with pressing and heating, the
continuous raw paper lOa is transferred by a fixed distance, `~
corresponding approximately to the length of the covering .
material 14 in this embodiment, to the downstream side by
the action of continuous paper transfer unit 102. That is ~.:
simultaneously, with pressing and heating of the covering
material 14 and postcard material 12 which were positioned
under the flat pressing and heating device 154 in the
previous cycle, the covering material 14 is transferred by , :
the prescribed distance as the continuous raw paper lOa
moves to the downstream side. :~
. ~ .
After the adhesive portion transfer table 118 has moved
by a prescribed amount on rails 174, the lineal pressing and ~'~
heating device 152 and flat pressing and heating device 154 : '~

or to the prescribed position on the original upstrearn side.
At this time, the press roller 162 presses the coveriny
material 14 while rotating.
Then, at the front end position of the following
covering material 14 transferred in the next cycle through
cuttiny and other processes of the continuous sheet 14a of
the covering materials, the adhesive portion transfer table
118 and the linear pressing and heating device 152 and flat
pressing and heating device 154 forming the pressins and
heating unit 150 are reenyaged. At this time, the covering
material 14 transferred in the previous cycle is positioned
under the flat pressing and heating device 154. The
continuous raw paper lOa adhered with the front end of the
covering material 14 of the next cycle is transferred by a
prescribed distance by the action of the continuous paper
transfer unit 102, and at the same time the front covering
i.. :. - . ;:
material 14 transferred previously in the earlier cycle is
pressed and heated by the flat pressing and heating device ` -

the encoder disposed on the continuous paper transler unit
102, and transfer of the covering material transfer unit
120, covering material cutter 126 and pressing and
heating unit 150 is controlled by a central processing
unit 176. However, the continuous raw paper lOa is
designed not to advance reversely in response to the
backward movement of the adhesive portion transfer table 118
and the linear pressing and heating device 152 and flat
pressing and heating device 154 of the pressing and heating
unit 150.
`~The pressing and heatiny unit 150 thus repeats a cycle
:,. .
of forward movement, reflection point (downstream side),~;~
backward movement and reflection point (upstream side), and
the covering material 14 is adhered suitably to the surface
of the postcard material 12 constituting the continuous
postcard 10 as shown in Fig. 1.
The continuous postcard 10 thus covered with the
covering material 14 uartly is folded suitably, and the

postcard stuff 210 comprises a postcard r.laterial 212, formed
.
in the size of the goverment postcard, and a sticking `~`
material, that is to say a covering material 212 stuck to a
part of this postcard Material 212. The covering material
1: ' ! I . : :~ . ,,
214 is formed integral with the postcard material 212 in a
manner of extending from one end thereof and is stuck to the
. ~: .
postcard material 212 in a folded-back fashion.

I'winning'' or "blank" and a confidential matter 213b such as a
information of the finance or the insurance are formed on the
surface of the postcard rllaterial 212.
The covering- material 214 comprises a base material
formed integral with the postcard material 212 in a manner of
extending from one end thereof.
The base material 218 is formed with a relatively soft
material such as pa~er, synthetic resin film and the like
which can be cut by a scissors or the like. And on one main
surface of the base rnaterial 218 a suppression layer 220 is
formed.
On the surface of the suppression layer 22Q, the first
heat adherent resin layer 222 is formed by coating a heat
adherent resin with a weak adhesive strength as heating and
extruding it, or by gravure or silk screen printiny as
dissolving it in a solvent or despersing in water and the
first heat adherent resin layer 222 has a weak adhesive
strength.
The first heat adherent resin layer 222 is formed to
melt at about 100C to 200C so as to be adhered to the
postcard material 212 made of paper or the like with a weak
adhesive strength.
As an example of said heat adherent resin having a weak
adhesive strength, adhesives of EVA group of the same as the
aforementioned embodiment shown in Fig. 1 may be selected.
2~29867 ;
., ~ :.,
Further, on the surface of the first heat adherent resin
layer 222, a s~cond heat adi-lerent resin layer 224 haviny a
stron~ adhesive strength is formed. In this embodirnent, the
second heat adherent resin layer 224 is formed at both sides
in the lengthwise direction of the postcard Material 12, that
is, in the fixed width at the upside and downside of the
covering material 14. Moreover, the second heat adherent
resin layer 224 is formed at both sides in the breadthwise
direction of the postcard material 12, that is, at right and
left ends of the covering rnaterial 14 in spots. The second
heat adherent resin layer 224 is formed by coating a heat
adherent resin having a strong adhesive strength, for example
adhesives of EVA yroup, stylene-butadiene-stylene copolymer,
stylene-isoprele-stylene copolymer in parts.
In this case, for example, the tackifier is mixed more
,
as compared with the heat adherent resin having a weak
adhesive strength or the release agent is mixed less as
compared with the heat adherent resin having a weak adhesive ~ ~-
strength, in the heat adherent resin having a strony adhesive
strentgth. The second heat adherent resin layer 224 rl~ay be
formed at only both sides of upside and downside or both
right side and left sides of the covering material 14.
Next, a method of manufacturing the coveing material 14
will be explained.
First, continuous paper for forming the postcard stuff

210 is prepared. The postcard material 212 portion and the
base material 218 portion are forrned continuously in the
direction of width of this continuous paper. Accordingly,
the length of the continuous paper in the direction of width
is a sum of the length of the postcard material 212 and the
length of the base material 218.
And, a suppression layer 20 is formed on one principal
surface of the base rnaterial 218 of the continuous paper.
As shown in Fig. 19, the postcard stuff 210 is
manufactured by the same appratus as appratus shown in
Fig. 3. The postcard stuff 210 has the covering rnaterial
214 which is formed by lamr,linating the suppression layer 220,
the first heat adherent resin layer 222 and the second heat
adherent resin layer 224 on one main surface of a part of the
base material 218, successively.
Subse~uently, this postcard stuff 210 is led to a
covering material stic};ing apparatus stickin~- this covering
material 214 to the postcard rnaterial 212. At this time, to
cover a confidential r~atter such as a residual amount
deposited in a bank which is formed on 2art of the surface of
.
the postcard with the covering material 214, it is necessary
to print proper characters in advance on a proper place, for
exmple, the lower column of the postcard rnaterial 212.
In addition, in the case of making this covering ~ -~
material 214 adhere, for example, to the lower column of the
32
2 ~ 2 ~
postcard, as shown in Fig. 20, the postcard stuff 210 is fed
sequentially, and it is folded bac~ at the boundary between
the postcard material 212 portion and the covering material
214 portion, and the covering material 214 and the postcard
material 212 are bonded. Then, the surface of postcard stuff
210 is pressed by a pressing roller, and the covering
material 214 is stuck to the surface of the postcard material
212. Then, the postcard stuff 210 is cut in a proper size,
and the postcard of the present invention is formed.
The adhered covering material 214 is adhered strongly
at a portion which the second adherent resin layer 224 is
formed and is adhered weakly at a portion which the second
adherent resin layer 224 is not formed. Thus, as shown in
Fig. 18A and Fig. 18B, the covering material 224 can be
peeled off relatively easily from the postcard material 212
by cutting the base material 218, the suppression layer 220
and the first heat adherent resin layer 222.
;; ,: .
In this case, the base material 218, the suppresion
layer 220 and the first heat adherent resin layer 222 can be
peeled off relatively easily at the portion which the second
heat adherent resin layer 224 is formed in spots. And, the
~,, . l -;.. .
lottery part 213a and the confidential matter 213b formed on
a surface of the postcard material 212 can be seeing.

thereof. In this embodiment, cuts 226a and 226b forming with
parforations are formed specifically in the upside and the
downside of the base material 218, the suppression layer 220,
and the first heat adherent resin layer 222 alony the
surrounding of the second heat adherent resin layer 224.
In this embodiment, as shown in Fig. 22, the covering
material 214 can be peeled off relatively easily from the
postcard material 212 by cutting the base rnaterial 218, the
sup~resion layer 220 and the first heat adherent resin layer
222 at the cuts 226a and 226b at a portion which the second
heat adherent resin layer 24 is not formed. Tllen, the
lottery part 213a and the confidential matter 213b on the
surface of the postcard material 212 can be seeiny.
In aforementioned embodiment, the center portion of the
covering material 14 in the up and down direction is peeld
off.
However, for example, a center portion of the covering
material 14 may be formed so as to peel off from the postcard
material 12 by formin~ the second heat adherent resin layer
24 along the surrounding of the covering material 14, and by
forming a cut along the second heat adherent resin layer 24
in the base material 18, the suppression layer 20 and the
first heat adherent resin layer 22.

12 when having the suppression layer 20, may be formed on one
main surface of the base material 18 or the surface of the
postcard material 12 when not having the suppression layer
20. .
IT1 the aforementioned embodiment, the cut is forrned -~
,................................................................ ... ... . :
along the surrounding of the covering material, a center
portion of the covering material can be cut by the cut.
In this case, as shown in Fig. 23, when each cuts are
constituted witll a linear cut portion 324a and a curvilinear
cut portion 324b respectively so as to overlap a part of one
cut 324 and a part of the next cut 324 in a direction for
peeling the covering material 312, the center portion of the
covering material 312 can be peeled off easily. In addition,
for peeling off the center portion of the covering material
412 easily, as shown in Fig. 24, for example, each linear
cuts 424 may be formed along edges of the base material 414
on a slant so as to overlap a part of one cut 424 and a part
of the next cut 424 in a direction for peeling off the
covering material 412.
In the postcard as sho~Jn in Fig. 23 and Fig. 24, by
pulling the covering material between the adjacent
perforations is broken as the direction thereof is shown by
- ~;
2~2~7
an arrow of dash-dot line, and the covering material of the
portion encompassed by the perforation is peeled off.
In said embodiment shown in Fig. 1 the covering
material is stucked to only one part of surface of the
postcard material.
However, as shown in Fig. 23 and 24, the same covering
material as the postcard material may be forr,led and the
covering material may be formed so as to be stuck to cover
the whole surface of said postcard material.
While the present invention has been particularly
described an dshown, it is to be understood that it is for
the purpose of illustration and example and not for
limitation. The spirit and scope of the invention is
therefore to be determined solely by the accompanying claims.
Industrial Applicability
