DESCRIPTION OF THE PREFERRED EMsoDIMENTs
Fig. 1A is an exploded perspective view showing an
embodiment of the present invention and Fig. 1C is a
sectional view taken along the line IC-IC in Fig. 1B.
A wrapper 10 in this embodiment is attached to an
article and suited for use as a label for indication on its
surface such details as the article's name, brand, quantity,
manufacturing lot No., date of manufacture, name of manufac-
turer, price and explanation and includes, for instance, a
rectangular base sheet 12. This base sheet 12 is, for
instance, made of a heat-sensitive recording paper. On one
principal surface of the base sheet 12 there is formed a
sticking adhesive layer 14 prepared by coating an adhesive
such as a pressure sensitive adhesive. To the surface of
this sticking adhesive layer 14 there is stuck tentatively a
~. :
rectangular release paper 16 made of paper or synthetic ~ ''
resin sheet. On the surface of the release paper 16 there
is formed a layer of releasing agent such as one based on
silicone. ~;
j A first cut line 18 is formed on this release paper 16.
'` ` This cut line 18 made near one longitudinal end of the
release paper 16 in the lateral''direction linearly from one
~l end to the other thereof. About the center of the release
.' .
~ 2 0 1 ~
paper 16 there is made a second U-shaped cut line 20. In
this case the second cut line 20 is connected with the first
cut line a little inward of both ends thereof, namely at
points 18a and 18b. That is, this cut line 20 is formed
from the points 18a and 18b of the cut line 18 extending
longitudinally toward the other end of the release paper 16.
This release paper 16 can be peeled off wholly or in
the portion 17a defined by the first and second cut lines to
thereby reveal the sticking adhesive layer 14.
This release paper 16 can also be stripped in the
portion outside the first cut line 18 to partly reveal the
sticking adhesive layer 14 thereby. It is also possible to
strip the portion 17b outside the second cut line 20 of the
release paper 16 to reveal the sticking adhesive layer 14
also partly.
Thus, with this wrapper 10 the release paper 16 can be
peeled off either wholly or partly by means of the first cut
line 18 and the second cut line 20. The other principal
surface of the base sheet 12 of this wrapper 10 has made
therein a perforation 22 for stripping. This perforation
is made to define a portion a bit smaller than the portion
defined by the first and second cut lines 18 and 20. As
shown in Fig. 1C this perforation 22 is made in the base
sheet 12 inward of the first cut line 18 and the second cut
lLne 20.
. . .

~ ; 2~4~3
This wrapper 10 can, as shown in Fig. 5, be stuck to
the surface of a delivered article 29 by means of the
sticking adhesive layer 14 revealed by peeling the portion
17b outside the second cut line 20 of the release paper 16.
This wrapper lO is so designed that a bag 24 is formed
between about the center portion 1 7c, namely the portion
inside the second cut line 20 of the release paper 16, and
the surface of the delivered article 29. This bag 24 has
its opening 24a in the middle part of the first cut line 18.
And through this opening 24a documents 28 accompanying the
delivered article 29 such as delivery note and slips can be
contained in the bag 24 of this wrapper 10. Further, the
sticking adhesive layer 14 can be revealed by peeling the
portion 17a outside the cut line 18. It is, therefore,
possible to have one end portion of the base sheet 12 stuck
to the surface of the delivered article 29 by means of the
sticking adhesive layer 14 to thereby seal the opening 24a
of the bag 24. Hence there is no risk of the contained
documents 28 accidentally slipping out of the bag 24. Since
the documents 28 contained in the bag 24 are covered by the
.
base sheet 12 and the central portion 1 7c of the release
~'jpaper 16, hence soiling of the documents 28 contained can be
prevented without fail and there is no fear of the documents
28 contained being lost.
~iIn order to take the documents contained 28 out of the
: I :
':, . .:
,~ 201g4~3
bag 24 the central portion o~ the base sheet 12 may be ;
stripped off by cutting along the perforation 22. As
examples of the documents 28 contained in the bag 24 formed
by sticking this wrapper 10 may be cited, besides delivery
note and slips, warranty card, instruction manual, label and
I sticker, but anything in flexible sheet form may be
I containable. ~ -
~ Since with this wrapper 10 the base sheet 12 is made of
¦ a heat-sensitive developing recording paper, the article's
¦ name, price, date of manufacture, manufacture's name, -; ;
¦ "delivery note contained", "warranty card contained","in-
~ struction manual contained" and the like can be printed on
¦ its surface by a heat-sensitive printer. Further, although
j in this embodiment the heat-sensitive developing recording
paper is used as material of the base sheet 12, but a ;~
synthetic resin such as polypropylene and polyethylene may
well be used instead. - `~

~ Fig. 2 is an illustratory view showing an exampie of
3 the equipment for manufacturing a wrapper as an embodiment
of the inventionO
An equipment 100 includes a retaining roller 102. And
the retaining roller 102 has retained thereon a belt-like
continuous sheet of release paper 16a in roll form. The
~ continuous sheet of release paper 16a retained on the
I retaining roller 102 has one end thereof unwound and that
:;
~ ` -20~8413
:i
end is led to a printing or coating device 104.
The printing or coating device 104 is for printing or
coating an adhesive such as a pressure-sensitive adhesive on
the surface of the release paper sheet 16a and comprises
three rollers 104a, 104b and 104c. The roller 104a has a
3 part thereof immersed in the adhesive 14a filled in a pan
~3 (not shown). The rollers 104b and 104c are arranged on the
transfer path for the sheet of release paper 16a to be
sandwiched therebetween and the roller 104a is kept in
contact with the roller 104b. As the rollers 104b and 104c
are driven to rotate, the sheet of release paper 16a guided
:3 therebetween has the adhesive 14a printed or coated on the
surface thereof.
The sheet of release paper 16a with the adhesive 14a
printed or coated thereon is then led to a drier 106
! ~ .
including a heater. In the drier 106 the adhesive 14a
printed or coated on the sheet of release paper 16a is dried
~ to form an adhesive layer 14b which serves as a sticking
3 adhesive layer 14. The sheet of release paper 16a with the
adhesive layer formed thereon is then led to a laminating
..~
device 108.
Meanwhile, the belt-like continuous heat-sensitive
developing recording paper 12a used as the base sheet 12 of
~, the present invention is retained in roll form on another
¦ retaining roller 110. And the heat-sensitive developing
`' 8

recording paper 12a has one end thereof unrolled and led to ~
the laminating device 108. ~-
The laminating device 108 includes two rollers 108a and ;
108b and the laminate of the sheet of release paper 16a and
the adhesive layer 14b and the heat-sensitive developing
recording paper 12a is led into therebetween so that the the
heat-sensitive developing recording paper 12a is laminated
on the adhesive layer 14b. And as these rollers 108a and
108b are driven to rotate, a laminate of the adhesive layer
14b and the lik~ and the heat-sensitive developing recording
paper 12a are laminated. That is, on the bëlt-like sheet of
release paper 16a, the adhesive layer 14b to serve as the
sticking adhesive layer 14 and the heat-sensitive developing
recording paper 12a used as the base sheet 12 are laminated
3 successively.
~;
Then, the formed laminate is led to the cut line making
I device 112. The cut line making device 112 includes a
plate-like so-called die cutter (not shown) having tooth
profiles (not shown) corresponding to the first cut line 18
`I and the second cut line 20. And by this die cutter (not
i~ shown) the first cut line 18 and the second cut line 20 are
made in the sheet of release paper 16a. The cut line making
device 112 may as well be a roll with cut line tooth

made, is led to the perforating device 114. The perforating
device 114 includes the plate-like so-called die cutter (not
shown) having perforation tooth profile (not shown). And
this die cutter (not shown) can be used to make a
perforation 22 in the heat-sensitive developing recording
paper 12a. The perforating device 114 may as well be a roll
with perforating profiles, the so-called die roll.
The continuous wrapper 10 is cut by a cutter 116 into
individual wrappers 10.
Figs. 3 and 4 are illustratory views showing another
example of the equipment for manufacture of the wrapper as
an embodiment of the present invention, Fig. 3 is another
illustratory view showing an example of the equipment for
manufacturing a laminate and Fig. 4 is a further
illustratory view showing an example of the equipment for
manufacture of the wrapper shown in Figs. lA through 1C by
the use of the laminated sheet shown in Fig. 3.
This laminated sheet 30 is made by laminating the
adhesive layer 14a for serving as the sticking adhesive
layer 14 and the heat-sensitive developing recording paper
12a used as the base sheet 12 in this order successively.
An equipment 150 includes a retaining roller 152 for
retaining the sheet of release paper 16a in roll form. The
sheet of release paper 16a retained on the retaining roller
152 has one end thereof unrolled and led to a printing or

,
coating device 154.
- The printing or coating device 154 is for printing or
coating an adhesive 1 4a such as a pressure-sensitive
adhesive on the surface of the sheet of releas~ paper 16a
: ~ :~
and includes two rollers 154a and 154b. The roller 154a has
its lower part immersed in the adhesive 14a filled in a pan
, : .
1 54c. Hence, as the rollers 1 54a and 154b are driven to
rotate, the adhesive 1 4a is printed or coated on the surface
of the sheet of release paper 116a led therebetween.
- And the sheet of release paper 1 6a with the adhesive
1 4a printed or coated thereon is led to a drier 156
including, for instance, a heater. In the drier 156 the
adhesive 14a printed or coated on the sheet of release paper
16a is dried for the adhesive layer 14b to be formed. The
sheet of release paper 16a is led to the laminating,
158.
Meanwhile, the belt-like recording paper such as the
heat-sensitive developing recording paper 12a to be used as
the base sheet 12 is retained in roll form on another
~¦retaining roller 160. And the heat-sensitive developing
recording paper 12a has one end thereof unrolled and led to
. . .:: .:
the laminating device 158.
The laminating device 158 includes two rollers 158a and -~
158b and a laminate of the sheet of release paper 16a and
the adhesive layer 1 4b and the heat-sensitive developing

recording paper 12a are led into therebetween or the heat-
sensitive developing recording paper 12a to be laminated on
the adhesive layer 14b. And as the rollers 158a and 158b
are driven to rotate, a laminate of the adhesive layer 14b
and the like and the heat-sensitive developing recording
paper 12a are laminated and the laminated sheet 30 is thus
formed.
The formed laminated sheet 30 thus formed is wound in
roll form on the winding roller 170 and is retrained
thereby.
Meanwhile, a device 180 includes a retaining roller 182
and on this retaining roller 182 the laminated sheet 30 as
shown in Fig. 3 is retained in roll form. And the
laminated sheet 30 has one end thereof unrolled and led into
a cut line making device 184.
This cut line making device 184 includes a plate-like
so-called die cutter (not shown) having tooth profiles (not
shown) for the first cut line 18 and the second cut line 20.
And by this aie cutter (not shown) the first cut line 18 and
the second cut line 20 are made in the sheet of release
paper 16a made of the laminated sheet 30. The cut line
making device 184 may as well be a roll with tooth profiles,
so-called die roll. ~
Then, the laminate of the sheet of release paper 16a
an~ the like with cut lines made therein is led into a
~. .

perforating device 186. The perforating device 186 includes
a plate-like so-called die cutter (not shown) having
perforating tooth profile (not shown) roughly corresponding
to the peripheral portion of the second cut line 20. And by
this die cutter (not shown) the heat-sensitive developing
recording paper 12a has made therein the perforation 22.
The perforating device 186 may as well be a roll with a
perforating tooth profile, the so-called die roll.
The continuous wrapper 10 is cut by a cutter 188 into
individual wrappers 10.
In the aforementioned embodiment, if the sticking
adhesive layer 14 made of a pressure-sensitive adhesive is
formed only in the portion corresponding to the periphery
except in one end portion, the portion 17c inside the second
cut line 20 in the release paper 16 may not be provided.
Or, if an adhesion inhibiting layer is provided where about
the central portion 17c is stuck to the surface of the
sticking adhesive layer 14 by the use of a material
inhibiting the adhesive power of an adhesive such as an ink
of the ultraviolet ray curing type, about the central
portion 17c of the release paper 16 may possibly be
dispensed with.
In this embodiment a heat-sensitive developing
recording paper was used as material of the base sheet 12
but as this materlal a quality paper may also be used
13
.' ~
--``' t~ 201~1 3
;'t
~7 instead. Since, in such a case, the base sheet 12 is made
of the quality paper such details as the article's name,
.~t price and date of manufacture, the manufacturer's name, such
notes as "delivery note included," "warranty card included,"
and "instruction manual included" can be printed. If
printing of such details and notes is to be done by the use
of a heat-sensitive printer, a heat-sensitive developing
material may be formed on the surface of the quality paper
base sheet 12 by printing or coating a heat-sensitive
i~ developing material by the use of, for instance, a printing/
,71 coating device.
~$ Further, in this embodiment a continuous one wound in
roll form was selected as the heat-sensitive developing
recording paper 12a and the sheet of release paper 16a but
these may as well be in separated sheet form. Although in
this embodiment the continuous wrapper 10 cut into separate
I pieces of wrapper 10 by the use of a cutter, a perforating
device may be used instead of the cutter to make perforation
between adjacent pieces of wrapper 10. In this case, the
'.'7 individual wrappers 10 are naturally used after separation
~ along the perforation.
