FIG. 1 is a plan view of a label sheet 100 for delivery according to an embodiment of the present invention, and FIG. 2 is a schematic view of a label sheet 100 for a courier FIG. 3 is a cross-sectional view schematically showing a cross section of the delivery label sheet 100. FIG.

1 to 3, the delivery label sheet 100 according to an embodiment of the present invention includes a release paper 110, a binding paper 120, a display paper 130, a first pressure sensitive adhesive film 140, And a second pressure sensitive adhesive film (150).

The peeling paper 110 is positioned at the bottom of the delivery label sheet 100 of the present embodiment and the first adhesive layer 140 is formed on one side thereof and attached to the paper binding paper 120. The release paper 110 is separated and removed from the first pressure sensitive adhesive film 140 when the delivery label sheet 100 is attached to the delivery product. The separation of the release paper 110 allows the adhesive surface of the first pressure sensitive adhesive film 140 to be exposed to the outside to attach the adhesive paper 120 to the surface of the article to be delivered. That is, the release paper 110 of this embodiment is temporarily attached so as to block the adhesive surface of the first pressure sensitive adhesive film 140 from the outside.

The attachment paper 120 is positioned on one side of the release paper 110. The first adhesive layer 140 and the second adhesive layer 150 are located on both sides of the adhesive paper 120 and the adhesive paper 120 has adhesive force on both sides. The attachment paper 120 of the present embodiment is attached to the release paper 110 by the first pressure sensitive adhesive film 140 and attached to the display paper 130 by the second pressure sensitive adhesive film 150. The adhesive paper 120 of the present embodiment is configured such that when the release paper 110 is separated and the first adhesive layer 140 adheres to the surface of the courier article 100 with the courier label sheet 100, It serves as a support for attaching to the surface of the delivered goods. The recovery delivery table 132 divided by the cutting line 136 among the display sheets 130 is temporarily attached to the attachment paper 120 by the second adhesive film 150 and can be separated therefrom. This will be described later in more detail.

The display sheet 130 is exposed to the outermost side of the delivery label sheet 100 according to the present embodiment, and various information for delivering the delivery article is printed or recorded. The various information recorded on the display area 130 may be the same as the name, address and contact information of the courier sender and courier, and other information required by the courier delivering the courier item may be recorded.

The display sheet 130 of the present embodiment includes a recall delivery table 132 and a delivery table 134 that are distinguished by a cutting line 136. The courier delivery company records the necessary information in a partial area of the display page 130. [ The cigarette delivery table 134 wraps at least a portion of the edge of the collection delivery table 132. For example, the reciever delivery table 132 of the present embodiment may have a rectangular shape, and the descendent delivery table 134 may cover at least two sides of four sides of the reciever delivery table 132 in a rectangular shape. Therefore, the delivery table 134 of the present embodiment is formed so as to surround the edge of the delivery table 132 in a shape such as 'a' shape, 'b' shape or 'c' shape.

At this time, the recovery delivery table 132 and the delivery table 134 according to the present embodiment are separated by the cutting line 136, and after the delivery of the delivery product is completed, the delivery label sheet 100, the recovery delivery table 132 is separated and recovered.

At this time, the collection and delivery table 132 of this embodiment includes the collection area 133 in some areas. The second pressure sensitive adhesive layer 150 is not formed under the recovery area 133 as described later. Therefore, when the recovery and delivery table 132 is recovered, the separation from the attachment paper 120 is facilitated, assisting the recovery of the recovery delivery table 132. This will be described later in more detail.

Among the display areas of this embodiment, the parts including the recall delivery table 132 and the delivery list 134 and recording and displaying information necessary for delivery of the courier goods are defined as the display parts 132 and 134. [ A dummy portion 138 is defined as a portion surrounding the edges of the display portions 132 and 134, and then removed through a separate removal process. The dummy portion 138 also includes an edge region of the attachment paper 120. 1 to 3 show a state in which the dummy portion 138 is removed and the lower release paper 120 is exposed to the outside.

The cutting line 136 of this embodiment includes a first cutting line 136a and a second cutting line 136b. The first cutting line 136a distinguishes the recovery delivery table 132 and the delivery table 134 as described above and the second cutting line 136b separates the display portions 132 and 134 and the dummy portion 138 ).

The first adhesive layer 140 is positioned between the release paper 110 and the attachment paper 120 and attaches the release paper 110 and the attachment paper 120 as described above. At this time, the peel strength of the first adhesive layer 140 of the present embodiment on the adhered paper 120 may be greater than the peel strength of the first adhesive layer 140 on the peelable paper 110. When the release paper 110 is peeled from the first pressure sensitive adhesive film 140 interposed between the adhesive paper 120 and the release paper 110, the release paper 110 adhered to the first pressure sensitive adhesive film 140, The remaining part of the first pressure sensitive adhesive film 140 can be completely peeled off without remaining.

4 is a plan view schematically showing a region to which the second adhesive layer 150 is applied according to an embodiment of the present invention. 4, the second adhesive layer 150 of the present embodiment is located only in a part of the area between the display sheet 130 and the adherend paper 120, and a part of the display paper 130 and a part of the adherend paper 120 . The non-sticking area of the display sheet 130 which does not adhere to the adherend 120 is interposed between the display sheet 130 and the adherend paper 120 as the "recovery area 133" And will be described in more detail hereinafter.

On the other hand, the first adhesive layer 140 adheres the adhesive paper 120 to the surface of the courier article after the release paper 110 is separated, and when the detachable courier sheet 132 is separated from the surface of the courier article, Sensitive adhesive material having a peel strength higher than the peel strength of the second pressure-sensitive adhesive layer 150 so that the second pressure-sensitive adhesive layer 120 does not separate. Accordingly, even after the release paper 110 is separated from the adhesive paper 120, the first pressure sensitive adhesive layer 140 of the present embodiment can maintain the adhesive force on the surface exposed to the outside, .

The second pressure sensitive adhesive film 150 of the present embodiment may be formed by applying a liquid pressure sensitive adhesive on the adherend paper 120, followed by drying or curing. The indicator 130 is disposed and attached along the second pressure-sensitive adhesive film 150 after the liquid pressure-sensitive adhesive is applied on the adhesive paper 120. [ In this case, since the adhesive force is reduced after the pressure-sensitive adhesive is completely dried or cured, the display paper 130 must be attached before the liquid pressure-sensitive adhesive forming the second pressure-sensitive adhesive layer 150 is dried or cured.

Since the adhesive is applied only to a part of the lower surface of the display sheet 130, that is, the area corresponding to the attachment area 135 excluding the recovery area 133, when the display sheet 130 is adhered on the liquid adhesive, The air existing in the area corresponding to the recovery area 133 can not be discharged to the outside and is trapped between the display paper 130 and the attachment paper 120. The air layer formed between the display sheet 130 and the adherend 120 may be diffused along the pressure sensitive adhesive during the pressing process for adhesion between the display sheet 130 and the adherend 120, The adhesive strength between the attachment region 135 of the adhesive sheet 130 and the adhesive paper 120 may be weakened, resulting in product failure.

Referring again to FIGS. 1 and 2, in order to prevent the generation of air bubbles which may generate various defects, the display paper 130 of the present embodiment is configured such that air existing between the display paper 130 and the attachment paper 120 is discharged The exhaust port 133a is formed in the recovery area 133 of the recovery delivery table 132 so that the exhaust port 133a can be formed. The second adhesive layer 150 does not exist under the recovery area 133 and the display sheet 130 corresponding to the recovery area 133 can directly contact the adherend 120 as shown in FIG.

The remaining area of the collection delivery manifest 130 excluding the collection area 133 is defined as an attachment area 135. [ The second adhesive layer 150 is present on the lower surface of the attachment region 135 and on the underside of the delivery table 134. That is, the attachment region 135 and the delivery note 134 of the present embodiment can overlap with the second adhesive film 150. Therefore, the attachment region 135 and the delivery sheet 134 of the present embodiment can be attached to the attachment paper 120 by the second adhesive film 150 as shown in FIG.

According to the present embodiment, only the delivery table 134 and the attachment region 135 are attached to the attachment paper 120 by the second adhesive film 150 and the second The release of the recovery delivery table 132 including the recovery area 133 can be made easier since the adhesive film 150 is not present and the separation from the binding paper 120 is more free.

FIG. 6 is a view showing an enlarged view of the recovery area 133 of FIG. 5 to be. Referring to FIGS. 5 and 6, the recovery area 133 according to one modification of the present embodiment may include a plurality of exhaust ports 133a. In Fig. 6, the recovery area 133 of Fig. 5 is enlarged more greatly. The exhaust port 133a of the present embodiment is located in the recycling delivery table 132 having a rectangular shape. For example, as shown in FIGS. 1 and 2, the collection area 133 of the present embodiment is formed in a triangle in an area including any one of the four corners of the rectangular collection delivery table 132.

Referring to FIG. 6, the exhaust port 133a of the present embodiment may be formed through the display sheet 130 at a position where the center of gravity of the triangle-shaped recovery area 133 is formed. The center of gravity of the triangle is defined as the intersection of the lines connecting the vertices of the vertices of each side of the triangle. When the exhaust port 133a is formed at the position of the center of gravity of the triangle, it is possible to smoothly discharge the air that is concentrated toward the recovery area 133, thereby more effectively preventing the undesirable diffusion of the air layer.

Further, in order to exert a more effective exhausting effect as shown in FIG. 6, exhaust ports 133a may be further formed at the midpoints of the lines connecting the vertexes of the triangles from the center of gravity of the triangles. In the case of including a plurality of exhaust ports 133a, the air can be discharged more smoothly, and it is more effective in preventing air layer diffusion.

However, this is only an example, and the formation position and size of the exhaust port 133a may be variously modified. Therefore, the exhaust port 133a may be formed at any position within the recovery area 133, and even if the diameters of the plurality of exhaust ports 133a are different from each other, they may be included in the scope of the present invention.

The above description has been made with respect to the label sheet 100 for delivering goods according to an embodiment of the present invention.
