~ESCRIYTION OF Th~ PRE3l~DgED EMBODIMENTS
Fig. lA is an exploded perspective view showing a wrapper 10 according to an embodiment of the present inven~
tion. Fig. lB is a perspective view showing the wrapper 10 shown in Fig. lA. Fig. lC is a sectional view ta~en along the line lC-lC of Fig. lB.
A wrapper ~0 of the embodiment is stuck to goods and suitable for being used as a la~el attached to goods so as to indicate items such as the name, brand, guantity, lot number, manufactured date, manufacturer's na~e, price, and explanation of the goods. The wrapper 10 includes a base sheet 12. The base sheet 12 is made of, for example, heat-sensitive reoording paper. A sticking adhesive layer 14 consisting of an adhesive such as a pressure sensitive adhesive is formed on one principal surface of the base sheet 12. A rectangular release paper ~6 consisting of paper and a synthetic resin sheet is temporarily adhered to :

2~2~28~

the surface ~f the sticking adhesive layer 14. The size of the re~ease paper 16 is the same as that of the base sheet 12. ~ release agent layer consisting of a silicon agent such as silicon is ~ormed on one principal surface of the release paper 16.
The release paper 16 has a H-shaped cut line 18 contin-uously formed such that the cut line is positioned within the periphery thereof and both ends thereof are connected to each o~her. Thus, the cut line 18 divides the release paper 16 into an bag accommodating part 16a and a stickin~ part 16b. The area o~ the ~ag accommodating part 16a is smaller ~han that of the base sheet 12. Opposed rectangular conca~e portions 20 and 22 are formed len~thwise from the center of each shorter side of an imaginary rectangle formed by the cut line 18 so that the cut line 18 is ~-shaped in a plan view.
The cut line 18 allows the sticking adhe~ive layer 14 to be exposed ~y releasing the sticking part 16b from the sticklng adhesive layer 14. As a result, the sticking adhesive layer 14 connects the bag accommodating part 16a and the base sheet 12 with each other. Perforations 24 are formed on the ~ase sheet 12. The axea surrounded with the line connecting the perforations 24 is a little smaller than that of the ~ag accommodating part 16a.

-` 2~2~8~

~ s shown in Fig. 5, in order to adhere the wrapper 10 to the surface of, for example, goods (A) to be delivered, the sticking part 16b of the release paper 16 is released from the sticking adhesive layer 14. Thus, the sticking adhesive ~ayer 14 is adhered to the surface o~ the goods (A). As a result, a bag accommodating part 26 is formed .. .
between the bag accommodating part L~a and the sur~ace of the goods IA)~ The bag accommodating part 26 accom~odates a rectangular bag 28 containing an article 30, for example, a bill o~ parcel, a chit or the like.
The rectangular bag 28 is stuc~ to the goods (A) with the bag accommodating part 16a contacting with the bag 28 having an opening portian 28a. Each side of the rectangular bag 28 is positioned inside each side of the imaginary rectangle formed by the cut line 18. The bag 28 cons~sts of, for example, a synthetic resin such as a vinyl resin.
The article 30 such as a bill of parcel or a chit is accom-mo~ated in the bag 28 through the opening portion 28a.
The bag 2~ is connected to the base sheet 12 with the sticking adhesive layer 14 corresponding to the concave portions 20 and 22. That is, the concave portions 20 and 22 are formed to expose the sticking adhesive layer 14 and connect the bag 28 to the base sheet 12. ~ore specifically, the bag 28 is connected with the base sheet 12 at the 2~2~2~g predetermined position thereof through the concave portions 20 and 22.
After the bag 28 is adhered to the sticking adhesive layer 14 corresponding to the concave portions 20 and 22, the adhesive layer ~4 corresponding to the sticking part 16b stic~s to the surface of the goods ~A). As a result, the bag accommodating portion 26 can ~e sealed with the base sheet 12. Accordingly, the bag 28 does not slip off the.bag accommodating portion 26. Since the article 30 accommodated in the bag 28 is covered with the base sheet 12 and the bag accommodating part 16a, it is neither soiled nor lost.
Further, the bag 28 consists of a vinyl resin. Therefore, it ser~es as a means for waterproofing the article 30.
In order to take out the article from the bag 28 after the wrapper 10 stic~s to the surface of the goods ~A~, the center portion of the base sheet 12 is torn open along the perforations 24. The area surrounded with the line connect-ing the perforations 24 is sma~ler than that of the imagi-nary rectangle formed by the cut line 18 and greater than that of the :rectangular bag 28. That is, the perforations 24 are formed into the base sheet.12 so that the lines connecting the perforations 24 are positioned outside the periphery of the bag 28 and inside the imaginary rectangle fo~med by the cut line 18. The article.30 to be accommodat-ed in the bag 28 includes flexible sheets, for example, a si~

2~262~8 bill of parcel, a chit, a letter o~ guarantee, a label or the like.
. ::
According to the wrapper 10, the base sheet 12 thereof consists of heat-sensitive recording paper, a display such as `'bill of parcel is enclosed", "letter of guarantee is enclosed" or "manual is enclosed" is made on the surface of the ~ase sheet 12 by applyin~ the heat-sensitive recordin~
paper to a thermosensitive printer. As the material of the base sheet 12, the heat-sensitive recording paper may ~e replaced with a synthetic resin such as polypropylene or polyethylene.
