Description

[Technical Field]

[0001] The present invention relates to a label sheet to be attached to a package containing a container for an item. [Background technology]

[0002] 2. Description of the Related Art Conventionally, in order to indicate the contents of a packaged item, a label sheet indicating the contents of the item has been attached to the surface of the package.

[0003] For example, Patent Document 1 is recognized to describe a pharmaceutical label 1 comprising a label sheet 2 having an adhesive layer 4 on its attachment surface and a release sheet 3 removably attached to the adhesive layer 4 side of the label sheet 2, the label sheet 2 having a display section 2a that displays the contents of the pharmaceutical and an outer frame section 2b that surrounds the outside of the display section 2a and separates it from the display section 2a, the release sheet 3 being divided into an inner section 3a and an outer section 3b by a slit 3c within the area of ​​the outer frame section 2b of the label sheet 2 (see Figure 1, etc.). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-161366 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the pharmaceutical label 1 described in Patent Document 1, the area of ​​the adhesive layer 4 exposed after the outer portion 3b of the release sheet 3 is peeled off and before the inner portion 3a of the release sheet 3 is peeled off is small, i.e., the distance from the outer periphery of the adhesive layer 4 to the outer periphery of the inner portion 3a of the release sheet 3 is short, so there is a problem that the adhesive strength of the pharmaceutical sheet 1 to the pharmaceutical bag 5 is insufficient and the pharmaceutical sheet 1 peels off from the pharmaceutical bag 5.

[0006] Therefore, in order to increase the adhesive strength of the pharmaceutical sheet 1 to the pharmaceutical bag 5, one method is to enlarge the area of ​​the adhesive layer 4 to prevent the pharmaceutical sheet 1 from peeling off from the pharmaceutical bag 5, but in that case, there is a problem that the overall size of the pharmaceutical sheet 1 would be increased.

[0007] Furthermore, the pharmaceutical sheet 1 (hereinafter referred to as "label sheet") described in Patent Document 1 needs to be peeled from the outer frame 2b with the display portion 2a showing the contents of the pharmaceutical and then attached to another container, and therefore needs to be peeled from the outer frame 2b with the adhesive layer 4 firmly held on the display portion 2a.

[0008] The present invention has been made in response to the above-mentioned problems of the prior art, and aims to provide a label sheet that increases the adhesive strength of a label sheet after the outer portion of the release sheet has been peeled off but before the inner portion of the release sheet has been peeled off, without increasing the overall size of the label sheet, and that allows the display portion to be reliably peeled off from the sheet body while the adhesive layer is firmly held in the display portion. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, a label sheet according to a first aspect of the present invention has a display section on which information is displayed, and an outer frame section that is disposed separately from the display section so as to cover the outer periphery of the display section, and comprises a sheet body having an adhesive layer on one side, and a release sheet that is releasably attached to the adhesive layer on the opposite side of the sheet body with the adhesive layer in between, and that is separated into an inner section and an outer section within the outer frame area; The outer portion of the release sheet has at least one protrusion extending toward the display portion of the sheet body.

[0010] A second aspect of the present invention is the label sheet of the first aspect, wherein the tip of the at least one protrusion is in contact with the outer periphery of the display portion in a plan view.

[0011] In addition, a third aspect of the present invention is characterized in that, in the label sheet of the second aspect, the width of the at least one protrusion becomes narrower toward the display area, and the tip of the at least one protrusion is in point contact with the outer periphery of the display area when viewed in a plane.

[0012] In addition, a fourth aspect of the present invention provides a label sheet having a substantially rectangular display area displaying information and an outer frame area separated from the display area so as to cover the outer periphery of the display area; the label sheet also comprises a sheet body having an adhesive layer on one side; and a release sheet separated into an inner portion and an outer portion within the outer frame area and removably attached to the adhesive layer on the opposite side of the sheet body with the adhesive layer in between, the release sheet having a plurality of protrusions formed intermittently along the substantially rectangular sides of the display area and extending toward the display area of ​​the sheet body.

[0013] In addition, a fifth aspect of the present invention is characterized in that, in the label sheet of the fourth aspect, the tip of at least one of the multiple protrusions is in contact with the outer periphery of the display portion when viewed in a plane.

[0014] In addition, a sixth aspect of the present invention is characterized in that, in the label sheet of the fifth aspect, the width of at least one of the multiple protrusions narrows toward the display area, and the tip of the at least one protrusion is in point contact with the outer periphery of the display area when viewed in a plane.

[0015] In addition, a seventh aspect of the present invention is characterized in that, in the label sheet of any of the fourth to sixth aspects, the multiple protrusions are formed excluding a predetermined area extending radially from the approximately rectangular corner of the display area.

[0016] In addition, an eighth aspect of the label sheet of the present invention has a substantially oval-shaped display area displaying information, and an outer frame area that is arranged separately from the display area so as to cover the periphery of the display area; the label sheet comprises a sheet body with an adhesive layer on one side, and a release sheet that is removably attached to the adhesive layer on the opposite side of the sheet body with the adhesive layer in between, and is separated into an inner portion and an outer portion within the area of ​​the outer frame, and the outer portion of the release sheet has a plurality of protrusions that are formed intermittently along the circumference of the substantially oval shape of the display area and extend toward the display area of ​​the sheet body.

[0017] In addition, a ninth aspect of the present invention is characterized in that, in the label sheet of the eighth aspect, the tip of at least one of the multiple protrusions is in contact with the outer periphery of the display portion when viewed in a plane.

[0018] In addition, a tenth aspect of the present invention is characterized in that, in the label sheet of the ninth aspect, the width of at least one of the multiple protrusions narrows toward the display area, and the tip of the at least one protrusion is in point contact with the outer periphery of the display area when viewed in a plane.

[0019] Furthermore, an 11th aspect of the present invention is characterized in that, in the label sheets of the 8th to 10th aspects, the multiple protrusions are formed except for a predetermined area extending radially from the end of the approximately elliptical shape of the display area. [Effects of the Invention]

[0020] The label sheet of the first aspect of the present invention comprises a sheet body having a display area displaying information and an outer frame area separated from the display area so as to cover the periphery of the display area, the sheet body having an adhesive layer on one side, and a release sheet on the opposite side of the sheet body, with the adhesive layer in between, which is removably attached to the adhesive layer and separated into an inner portion and an outer portion within the outer frame area. The outer portion of the release sheet has at least one protrusion extending toward the display area of ​​the sheet body. This increases the adhesive strength of the label sheet after peeling off the outer portion of the release sheet but before peeling off the inner portion of the release sheet, without increasing the overall size of the label sheet, and allows the display area to be reliably peeled off from the sheet body while the adhesive layer is firmly held in place on the display area.

[0021] Furthermore, according to the second aspect of the present invention, in the label sheet of the first aspect, the tip of at least one protrusion is in contact with the outer periphery of the display unit when viewed in a plane. This further increases the adhesive strength of the label sheet after the outer portion of the release sheet is peeled off but before the inner portion of the release sheet is peeled off, and allows the display unit to be reliably peeled off from the sheet body while the adhesive layer is firmly held on the display unit.

[0022] Furthermore, according to the third aspect of the present invention, in the label sheet of the second aspect, the width of at least one protrusion becomes narrower toward the display portion, and the tip of at least one protrusion is made to make point contact with the outer periphery of the display portion in a planar view. Therefore, in addition to the effect of the label sheet of the second aspect, the display portion can be more reliably peeled off from the sheet body while the adhesive layer is firmly held in place on the display portion.

[0023] In addition, a label sheet according to a fourth aspect of the present invention comprises a sheet body having a substantially rectangular display area displaying information and an outer frame area separated from the display area so as to cover the periphery of the display area, the sheet body having an adhesive layer on one side, and a release sheet on the opposite side of the sheet body, with the adhesive layer in between, removably attached to the adhesive layer and separated into an inner portion and an outer portion within the outer frame area. The outer portion of the release sheet has a plurality of protrusions formed intermittently along the substantially rectangular sides of the display area and extending toward the display area of ​​the sheet body. This increases the adhesive strength of the label sheet after peeling off the outer portion of the release sheet but before peeling off the inner portion of the release sheet, without increasing the overall size of the label sheet, and allows the display area to be reliably peeled off from the sheet body while the adhesive layer is firmly held in place on the display area.

[0024] Furthermore, according to the fifth aspect of the present invention, in the label sheet of the fourth aspect, the tip of at least one of the multiple protrusions is in contact with the outer periphery of the display unit when viewed in a plane. This further increases the adhesive strength of the label sheet after the outer portion of the release sheet is peeled off but before the inner portion of the release sheet is peeled off, and allows the display unit to be reliably peeled off from the sheet body while the adhesive layer is firmly held on the display unit.

[0025] Furthermore, according to a sixth aspect of the present invention, in the label sheet of the fifth aspect, the width of at least one of the multiple protrusions tapers toward the display portion, and the tip of at least one of the protrusions is in point contact with the outer periphery of the display portion in a planar view. This not only achieves the effects of the label sheet of the fifth aspect, but also makes it possible to more reliably peel the display portion from the sheet body while the adhesive layer is firmly held in place on the display portion.

[0026] Furthermore, according to the seventh aspect of the present invention, in the label sheet of any of the fourth to sixth aspects, the multiple protrusions are formed except for a predetermined area extending radially from the approximately rectangular corner of the display unit. Therefore, in addition to the effects of the label sheet of any of the fourth to sixth aspects, the display unit can be more reliably peeled off from the sheet body while the adhesive layer is firmly held in the display unit, without increasing the size of the entire label sheet.

[0027] In addition, a label sheet according to an eighth aspect of the present invention comprises a sheet body having a substantially oval-shaped display area displaying information and an outer frame area separated from the display area so as to cover the periphery of the display area, the sheet body having an adhesive layer on one side, and a release sheet on the opposite side of the sheet body, with the adhesive layer in between, removably attached to the adhesive layer and separated into an inner portion and an outer portion within the outer frame area. The outer portion of the release sheet has a plurality of protrusions formed intermittently along the circumference of the substantially oval shape of the display area and extending toward the display area of ​​the sheet body. This increases the adhesive strength of the label sheet after peeling off the outer portion of the release sheet but before peeling off the inner portion of the release sheet, without increasing the overall size of the label sheet, and allows the display area to be reliably peeled off from the sheet body while the adhesive layer is firmly held in place on the display area.

[0028] Furthermore, according to the ninth aspect of the present invention, in the label sheet of the eighth aspect, the tip of at least one of the multiple protrusions is in contact with the outer periphery of the display unit when viewed in a plane. This further increases the adhesive strength of the label sheet after the outer portion of the release sheet is peeled off but before the inner portion of the release sheet is peeled off, and allows the display unit to be reliably peeled off from the sheet body while the adhesive layer is firmly held on the display unit.

[0029] Furthermore, according to a tenth aspect of the present invention, in the label sheet of the ninth aspect, the width of at least one of the multiple protrusions narrows toward the display unit, and the tip of the at least one protrusion is in point contact with the outer periphery of the display unit in a planar view. This not only achieves the effects of the label sheet of the ninth aspect, but also makes it possible to more reliably peel the display unit from the sheet body while the adhesive layer is firmly held in place on the display unit.

[0030] Furthermore, according to an eleventh aspect of the present invention, in the label sheet of any of the eighth to tenth aspects, the multiple protrusions are formed except for a predetermined area extending radially from the end of the approximately elliptical shape of the display unit. Therefore, in addition to the effects of the label sheet of any of the eighth to tenth aspects, the display unit can be more reliably peeled off from the sheet body while the adhesive layer is firmly held in the display unit, without increasing the size of the entire label sheet.

DETAILED DESCRIPTION OF THE INVENTION

[0032] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0033] (First embodiment) First, a first embodiment of the present invention will be described. Note that the drawings used in this embodiment are exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0034] In particular, since the present invention is characterized by the shape of the release sheet described later, in this embodiment and the embodiments described later, the distance between the back boundary line between the outer portion and inner portion of the release sheet described later and the outer periphery of the display portion described later, the distance between the back boundary line between the outer portion and inner portion of the release sheet and the outer periphery of the label sheet described later, and the shape and size of the first protrusion portion described later are illustrated as particularly long and large exaggerated.

[0035] Furthermore, since the present invention requires that the state of the front and back surfaces of the label sheet be compared for explanation, in each drawing of this embodiment and the embodiments described below, the components on the invisible side will be written in angle brackets.

[0036] Furthermore, in this embodiment and the embodiments described below, for convenience of explanation, the horizontal direction on the drawing will be referred to as the "horizontal direction," the vertical direction on the drawing will be referred to as the "vertical direction," the left side on the drawing will be referred to as the "left side," the right side on the drawing will be referred to as the "right side," the top side on the drawing will be referred to as the "upper side," and the top and bottom sides of the drawing will be referred to as the "lower side."

[0037] FIG. 1 is a plan view of a label sheet according to a first embodiment of the present invention, and FIG. 2 is a rear view of the label sheet.

[0038] As shown in Figures 1 and 2, the label sheet 1 of this embodiment is made of paper, resin, or a mixture of paper and resin, and is composed of a sheet body 2 that is generally rectangular in plan view, an adhesive layer 9 (see Figures 3 to 8) provided on one side (back side) of the sheet body 2, and a release sheet 3 that is generally rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2, with the adhesive layer 9 in between.

[0039] The sheet body 2 is made of paper material, resin material, or a material that is a mixture of paper material and resin material, and has an approximately rectangular display section 2a that displays information W1 such as the product name and manufacturing number, and an outer frame section 2b that covers the periphery of the display section 2a and is separated from the display section 2a by a front-side boundary line 4, and as mentioned above, an adhesive layer 9 is applied to the entire one side (back side) of the sheet body 2.

[0040] The release sheet 3 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2, with the adhesive layer 9 sandwiched between them, and has the same shape as the sheet body 2, being approximately rectangular in plan view.

[0041] Furthermore, within the outer frame portion 2b of the sheet main body 2, the release sheet 3 has an outer portion 3b separated by the back boundary line 7 and located outside the back boundary line 7, and an inner portion 3a also separated by the back boundary line 7 and located inside the back boundary line 7.

[0042] In addition, the outer portion 3b of the release sheet 3 is provided with eight first protrusions 5 (5a, 5b, 5c, 5d, 5e, 5f, 5g and 5h (corresponding to the "protrusions" of the present invention)) that are formed intermittently along the approximately rectangular sides of the display portion 2a and extend toward the display portion 2a of the sheet main body 2.

[0043] In addition, in this embodiment, in order to make it easier to peel off the corners of the approximately rectangular display section 2a from the sheet body 2, the eight first protrusions 5 are not formed in the corner regions 8 (8a, 8b, 8c and 8d) extending radially from the four approximately rectangular corners of the display section 2a.

[0044] Next, how to use the label sheet 1 described above will be described with reference to the drawings.

[0045] FIG. 3 is a diagram illustrating the operation of peeling the outer portion of the release sheet from the label sheet in the AA cross-sectional view of FIG. 2. FIG. 4 is a diagram illustrating the state in which the outer portion of the release sheet has been peeled from the label sheet and then attached to the substrate in the AA cross-sectional view of FIG. 2. FIG. 5 is a diagram illustrating the state in which the display portion has been peeled from the label sheet attached to the substrate in the AA cross-sectional view of FIG. 2.

[0046] 6 is a diagram illustrating the operation of peeling the outer portion of the release sheet from the label sheet in the B-B cross-sectional view of FIG. 2; FIG. 7 is a diagram illustrating the state in which the outer portion of the release sheet has been peeled from the label sheet and then attached to the substrate in the B-B cross-sectional view of FIG. 2; and FIG. 8 is a diagram illustrating the state in which the display portion has been peeled from the label sheet attached to the substrate in the B-B cross-sectional view of FIG. 2.

[0047] When using the label sheet 1, first, as shown in Figures 3 and 6, the outer portion 3b of the release sheet 3 is peeled off from the label sheet 1 while leaving the inner portion 3a of the release sheet 3 in place, and then the label sheet 1 from which the outer portion 3b has been peeled off is attached to a package P containing a container for an item, as shown in Figures 4 and 7.

[0048] In this case, the first protrusion 5 causes the horizontal width of the adhesive layer 9 attached to the packaging body P to be the longest on the left side DW1 and the longest on the right side DW2, and the vertical width of the adhesive layer 9 attached to the packaging body P to be the longest on the top side DL1 and the longest on the bottom side DL2 (see Figures 4 and 7), thereby increasing the adhesive strength of the label sheet 1 after the outer portion 3b of the release sheet 3 is peeled off and before the inner portion 3a of the release sheet 3 is peeled off.

[0049] Thereafter, as shown in Figures 5 and 8, the display portion 2a is peeled off from the label sheet 1 and attached to another item. However, in order for the peeled display portion 2a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 2a must be peeled off from the label sheet 1 with the adhesive layer 9a firmly held on the display portion 2a.

[0050] In the label sheet 1 of this embodiment, even though eight first protrusions 5 are present, after the outer portion 3b of the release sheet 3 is peeled off and before the inner portion 3a of the release sheet 3 is peeled off, the horizontal width of the adhesive layer 9 attached from the outer periphery of the display portion 2a to the outer periphery of the inner portion 3a is shortest on the left side XW1 and shortest on the right side XW2, and the vertical width of the adhesive layer 9 attached from the outer periphery of the display portion 2a to the outer periphery of the inner portion 3a is shortest on the top side XL1 and shortest on the bottom side XL2 (see Figures 4 and 7).

[0051] Therefore, since all of the adhesive layer 9 applied to the back surface of the display portion 2a is located on the upper surface of the inner portion 3a, not on the packaging body P (see Figures 4 and 7), the adhesive layer 9 is easily peeled off from the inner portion 3a, and the display portion 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9a is firmly held on the display portion 2a.

[0052] In this embodiment, the shape of the first protrusion 5 has been described as being approximately triangular and tapering toward the display unit 2a, but the first protrusion of this embodiment is not limited to an approximately triangular shape, and may be a polygonal shape such as an approximately square shape, or a curved shape such as an approximately semicircular shape or an approximately semi-elliptical shape, and even if it does not fall under these polygonal or curved shapes, it may be a shape that protrudes toward the display unit 2a.

[0053] Furthermore, in this embodiment, the number of first protrusions 5 is described as eight, but the number of first protrusions in this embodiment is not limited to eight, and may be any number, as long as it is one or more.

[0054] The label sheet 1 of this embodiment comprises a main sheet body 2 having a display area 2a displaying information W1 and an outer frame area 2b arranged separately from the display area 2a so as to cover the periphery of the display area 2a, the main sheet body 2 having an adhesive layer 9 on one surface, and a release sheet 3 removably attached to the adhesive layer 9 on the opposite side of the main sheet body 2 with the adhesive layer 9 in between. The release sheet 3 is separated into an inner area 3a and an outer area 3b within the area of ​​the outer frame area 2b, and the outer area 3b of the release sheet 3 has eight first protrusions 5 extending toward the display area 2a of the main sheet body 2. This increases the adhesive strength of the label sheet 1 after the outer area 3a of the release sheet 3 is peeled off but before the inner area 3a of the release sheet 3 is peeled off without increasing the overall size of the label sheet 1, and allows the display area 2a to be reliably peeled off from the main sheet body 2 while the adhesive layer 9 is firmly held on the display area 2a.

[0055] Furthermore, the label sheet 1 of this embodiment comprises a sheet body 2 having a substantially rectangular display area 2a displaying information W1 and an outer frame area 2b arranged separately from the display area 2a so as to cover the periphery of the display area 2a, the sheet body 2 having an adhesive layer 9 on one surface, and a release sheet 3 removably attached to the adhesive layer 9 on the opposite side of the sheet body 2 with the adhesive layer 9 in between. The release sheet 3 is separated into an inner area 3a and an outer area 3b within the area of ​​the outer frame area 2b, and the outer area 3b of the release sheet 3 is formed intermittently along the substantially rectangular sides of the display area 2a and has eight first protrusions 5 extending toward the display area 2a of the sheet body 2. This increases the adhesive strength of the label sheet 1 after peeling off the outer area 3b of the release sheet 3 but before peeling off the inner area 3a of the release sheet 3, without increasing the overall size of the label sheet 1. Furthermore, the display area 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display area 2a.

[0056] Furthermore, according to the label sheet 1 of this embodiment, the eight first protrusions 5 are formed excluding the four corner regions 8 extending radially from the four corners of the approximately rectangular shape of the display section 2a. This allows the display section 2a to be more reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display section 2a, without increasing the overall size of the label sheet 1.

[0057] (Second embodiment) Next, a second embodiment of the present invention will be described. Note that the drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0058] The second embodiment of the present invention will be described below. However, the plan view of the label sheet, the diagram explaining the operation of peeling the outer portion of the release sheet from the label sheet, the diagram showing the label sheet affixed to a substrate after the outer portion of the release sheet has been peeled from the label sheet, and the diagram showing the label sheet affixed to the substrate after the display portion has been peeled off are the same as those in FIGS. 1 and 3 to 8, and therefore their explanations will be omitted. Parts common to the first embodiment will be assigned the same reference numerals and their explanations will be omitted.

[0059] The label sheet 10 of the second embodiment has a different shape for the outer and inner parts compared to the label sheet 1 of the first embodiment. That is, in the first embodiment, the eight first protrusions 5 extending toward the display area 2a of the sheet body 2 did not contact the outer periphery of the planar display area 2a, but the first protrusions of this embodiment do contact the outer periphery of the planar display area.

[0060] FIG. 9 is a rear view of the label sheet of the second embodiment.

[0061] As shown in Figure 9, the label sheet 10 of this embodiment is also made of paper, resin, or a mixture of paper and resin, and is composed of a sheet body 2 that is generally rectangular in plan view, an adhesive layer 9 (see Figures 3 to 8) provided on one side (back side) of the sheet body 2, and a release sheet 13 that is generally rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2, with the adhesive layer 9 in between.

[0062] The release sheet 13 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2 from the adhesive layer 9, and has the same shape as the sheet body 2, being approximately rectangular in plan view.

[0063] Furthermore, within the outer frame portion 2b of the sheet main body 2, the release sheet 13 has an outer portion 13b separated by the back boundary line 17 and located outside the back boundary line 17, and an inner portion 13a also separated by the back boundary line 17 and located inside the back boundary line 17.

[0064] In addition, the outer portion 13b of the release sheet 13 is provided with ten first protrusions 15 (15a, 15b, 15c, 15d, 15e, 15f, 15g, 15h, 15j and 15k (corresponding to the "protrusions" of the present invention)) that are formed intermittently along the approximately rectangular side of the display portion 2a and extend toward the display portion 2a of the sheet main body 2.

[0065] Furthermore, since the ten first protrusions 15 in this embodiment are located on the opposite side of the sheet main body 2 across the adhesive layer 9, they do not directly contact the outer periphery of the display section 2a. However, as shown in Figure 9, in a planar view, the tips 15ac, 15bc, 15cc, 15dc, 15ec, 15fc, 15gc, 15hc, 15jc and 15kc (hereinafter referred to as "15ac, etc.") of the ten first protrusions 15 contact the outer periphery of the display section 2a.

[0066] In addition, in this embodiment, in order to make it easier to peel off the corners of the approximately rectangular display section 2a from the sheet body 2, the ten first protrusions 15 are not formed in the corner regions 18 (18a, 18b, 18c and 18d) extending radially from the four approximately rectangular corners of the display section 2a.

[0067] On the other hand, as described above, the inner portion 13a of the release sheet 13 is located inside the rear boundary line 17, but in this embodiment, the tip portions 15ac etc. of the ten first protrusions 15 are in contact with the outer periphery of the display section 2a in a planar view, and therefore the ten second protrusions 16 (16a, 16b, 16c, 16d, 16e, 16f, 16g, 16h, 16j and 16k) have a shape that protrudes outward from the outer periphery of the display section 2a.

[0068] Note that the ten second protrusions 16 do not all have the same shape; as shown in FIG. 9, second protrusions 16b, 16c, 16d, 16g, 16h and 16j have roughly the same rectangular shape, while 16a, 16e, 16f and 16k include four corner regions 18 extending radially from the four corners of the roughly rectangular shape of the display unit 2a, and have a larger rectangular shape than second protrusions 16b, 16c, 16d, 16g, 16h and 16j.

[0069] When using the label sheet 10, first, as shown in Figures 3 and 6, the outer portion 13b of the release sheet 13 is peeled off from the label sheet 10 while leaving the inner portion 13a of the release sheet 13 in place, and then the label sheet 10 from which the outer portion 13b has been peeled off is attached to a package P containing a container for an item, as shown in Figures 4 and 7.

[0070] In this case, the first protrusion 15 causes the adhesive layer 9 attached to the packaging body P to have a portion that is longer in the horizontal direction, and also causes the adhesive layer 9 attached to the packaging body P to have a portion that is longer in the vertical direction (see Figures 4, 7 and 9), thereby increasing the adhesive strength of the label sheet 10 after the outer portion 13b of the release sheet 13 is peeled off and before the inner portion 13a of the release sheet 13 is peeled off.

[0071] Thereafter, as shown in Figures 5 and 8, the display portion 2a is peeled off from the label sheet 10 and attached to another item. In order for the peeled display portion 2a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 2a must be peeled off from the label sheet 10 with the adhesive layer 9a firmly held on the display portion 2a.

[0072] In the label sheet 10 of this embodiment, due to the ten second protrusions 16, after the outer portion 13b of the release sheet 13 is peeled off and before the inner portion 13a of the release sheet 13 is peeled off, there is a horizontal and vertical region of the adhesive layer 9 applied from the outer periphery of the display portion 2a to the outer periphery of the inner portion 13a (see Figure 9).

[0073] Therefore, after the outer portion 13b of the release sheet 13 is peeled off and before the inner portion 13a of the release sheet 13 is peeled off, the adhesive layer 9 located on the upper surface of the inner portion 13a covers the entire display portion 2a and has ten second protrusions 16 (see Figure 9), so the adhesive layer 9 is easily peeled off from the inner portion 13a, and the display portion 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9a is firmly held on the display portion 2a.

[0074] In this embodiment, the shape of the ten first protrusions 15 has been described as being approximately rectangular facing the display unit 2a, but the first protrusions of this embodiment are not limited to being approximately rectangular, and may be polygonal, or curved shapes such as approximately semicircular and approximately semielliptical.Even if the shape is not included in these polygonal and curved shapes, it is sufficient as long as it protrudes toward the display unit 2a and its tip contacts the outer periphery of the display unit 2a.

[0075] Furthermore, in this embodiment, the number of first protrusions 15 is described as 10, but the number of first protrusions in this embodiment is not limited to 10, and may be any number, provided that it is one or more.

[0076] The label sheet 10 of this embodiment comprises a display area 2a displaying information W1 and an outer frame 2b arranged separately from the display area 2a so as to cover the periphery of the display area 2a. The label sheet 10 is also provided with a sheet body 2 having an adhesive layer 9 on one surface, and a release sheet 13 removably attached to the adhesive layer 9 on the opposite side of the sheet body 2 with the adhesive layer 9 in between. The release sheet 13 is separated into an inner portion 13a and an outer portion 13b within the area of ​​the outer frame 2b. The outer portion 13b of the release sheet 13 has ten first protrusions 15 extending toward the display area 2a of the sheet body 2. This increases the adhesive strength of the label sheet 10 after the outer portion 13a of the release sheet 13 is peeled off but before the inner portion 13a of the release sheet 13 is peeled off without increasing the overall size of the label sheet 10. The display area 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display area 2a.

[0077] Furthermore, according to the label sheet 10 of this embodiment, the tip portions 15ac of the ten first protrusions 15 are in contact with the outer periphery of the display portion 2a in a plan view, which further increases the adhesive strength of the label sheet 10 after the outer portion 13b of the release sheet 13 is peeled off but before the inner portion 13a of the release sheet 13 is peeled off, and the display portion 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display portion 2a.

[0078] Furthermore, label sheet 10 of this embodiment comprises a sheet body 2 having a substantially rectangular display area 2a displaying information W1 and an outer frame area 2b arranged separately from display area 2a so as to cover the periphery of display area 2a, and an adhesive layer 9 on one surface thereof; and a release sheet 13 removably attached to adhesive layer 9 on the opposite side of outer frame area 2b from the sheet body 2 with adhesive layer 9 in between. The release sheet 13 is separated into an inner portion 13a and an outer portion 13b within the area of ​​outer frame area 2b. Outer portion 13b of release sheet 13 is formed intermittently along the substantially rectangular sides of display area 2a and has ten first protrusions 15 extending toward display area 2a of sheet body 2. This increases the adhesive strength of label sheet 10 after outer portion 13b of release sheet 13 is peeled off but before inner portion 13a of release sheet 13 is peeled off without increasing the overall size of label sheet 10. Furthermore, display area 2a can be reliably peeled off from sheet body 2 while adhesive layer 9 is firmly attached to display area 2a.

[0079] Furthermore, according to the label sheet 10 of this embodiment, the ten first protrusions 15 are formed excluding the four corner regions 18 extending radially from the four corners of the approximately rectangular shape of the display section 2a. This allows the display section 2a to be more reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display section 2a, without increasing the overall size of the label sheet 10.

[0080] (Third embodiment) Next, a third embodiment of the present invention will be described. Note that the drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0081] The third embodiment of the present invention will be described below. However, the plan view of the label sheet, the diagram explaining the operation of peeling the outer portion of the release sheet from the label sheet, the diagram showing the label sheet affixed to a substrate after the outer portion of the release sheet has been peeled from the label sheet, and the diagram showing the label sheet affixed to the substrate after the display portion has been peeled off are the same as those in FIGS. 1 and 3 to 8, and therefore their explanations will be omitted. Parts common to the first embodiment will be assigned the same reference numerals and their explanations will be omitted.

[0082] The label sheet 20 of the third embodiment differs from the label sheet 1 of the first embodiment in the shapes of its outer and inner parts. That is, in the first embodiment, the eight first protrusions 5 extending toward the display area 2a of the sheet body 2 did not contact the outer periphery of the planar display area 2a, but the first protrusions of this embodiment make point contact with the outer periphery of the planar display area.

[0083] FIG. 10 is a rear view of the label sheet of the third embodiment.

[0084] As shown in Figure 10, the label sheet 20 of this embodiment is also made of paper material, resin material, or a mixture of paper material and resin material, and is composed of a sheet body 2 that is approximately rectangular in plan view, an adhesive layer 9 (see Figures 3 to 8) provided on one side (back side) of the sheet body 2, and a release sheet 23 that is approximately rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2, with the adhesive layer 9 in between.

[0085] The release sheet 23 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 2 from the adhesive layer 9, and has the same shape as the sheet body 2, being approximately rectangular in plan view.

[0086] Furthermore, within the outer frame portion 2b of the sheet main body 2, the release sheet 23 has an outer portion 23b separated by the back boundary line 27 and located outside the back boundary line 27, and an inner portion 23a also separated by the back boundary line 27 and located inside the back boundary line 27.

[0087] In addition, the outer portion 23b of the peel-off sheet 23 is provided with eight first protrusions 25 (25a, 25b, 25c, 25d, 25e, 25f, 25g and 25h (corresponding to the "protrusions" of the present invention)) which are formed intermittently along the approximately rectangular side of the display portion 2a and which are gradually tapered toward the display portion 2a of the sheet main body 2.

[0088] Furthermore, since the eight first protrusions 25 in this embodiment are located on the opposite side of the sheet main body 2 across the adhesive layer 9, they do not come into direct contact with the outer periphery of the display section 2a. However, as shown in FIG. 10, in a planar view, the tips 25ac, 25bc, 25cc, 25dc, 25ec, 25fc, 25gc and 25hc (hereinafter referred to as "25ac, etc.") of the eight first protrusions 25 come into point contact with the outer periphery of the display section 2a.

[0089] In addition, in this embodiment, in order to make it easier to peel off the corners of the approximately rectangular display section 2a from the sheet main body 2, the eight first protrusions 25 are not formed in the four corner regions 28 (28a, 28b, 28c and 28d) extending radially from the four approximately rectangular corners of the display section 2a.

[0090] On the other hand, as described above, the inner portion 23a of the peel-off sheet 23 is located inside the rear boundary line 27, but in this embodiment, the tip portions 25ac etc. of the eight first protrusions 25 are in point contact with the outer periphery of the display unit 2a in a planar view, and therefore the eight second protrusions 26 (26a, 26b, 26c, 26d, 26e, 26f, 26g and 26h) have a shape that protrudes outward from the outer periphery of the display unit 2a.

[0091] Note that the eight second protrusions 26 do not all have the same shape; as shown in FIG. 10, the second protrusions 26b, 26c, 26f and 26g are all approximately trapezoidal in shape, and the second protrusions 26a, 26d, 26e and 26h are shaped to include four corner regions 28 extending radially from the four corners of the approximately rectangular shape of the display unit 2a.

[0092] When using the label sheet 20, first, as shown in Figures 3 and 6, the outer portion 23b of the release sheet 23 is peeled off from the label sheet 20 while leaving the inner portion 23a of the release sheet 23 in place, and then the label sheet 20 from which the outer portion 23b has been peeled off is attached to a package P containing a container for an item, as shown in Figures 4 and 7.

[0093] In this case, the eight first protrusions 25 create portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the horizontal direction, and portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the vertical direction (see Figures 4, 7 and 10), thereby increasing the adhesive strength of the label sheet 20 after the outer portion 23b of the release sheet 23 is peeled off and before the inner portion 23a of the release sheet 23 is peeled off.

[0094] Thereafter, as shown in Figures 5 and 8, the display portion 2a is peeled off from the label sheet 20 and attached to another item. In order for the peeled display portion 2a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 2a must be peeled off from the label sheet 1 with the adhesive layer 9a firmly held on the display portion 2a.

[0095] In the label sheet 20 of this embodiment, due to the eight second protrusions 26, after the outer portion 23b of the release sheet 23 is peeled off and before the inner portion 23a of the release sheet 23 is peeled off, there is a horizontal and vertical area of ​​the adhesive layer 9 applied from the outer periphery of the display portion 2a to the outer periphery of the inner portion 23a (see Figure 10).

[0096] Therefore, after the outer portion 23b of the release sheet 23 is peeled off and before the inner portion 23a of the release sheet 23 is peeled off, the adhesive layer 9 located on the upper surface of the inner portion 23a covers the entire display portion 2a and has eight second protrusions 26 (see Figure 10), so the adhesive layer 9 is easily peeled off from the inner portion 23a, and the display portion 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9a is firmly held on the display portion 2a.

[0097] In this embodiment, the shape of the eight first protrusions 25 has been described as being gradually tapered toward the display section 2a of the sheet main body 2, but the first protrusions of this embodiment are not limited to such a shape and may be an approximately polygonal shape, or a curved shape such as an approximately semicircular shape or an approximately semi-elliptical shape.Even if the shape is not included in these polygonal and curved shapes, it is sufficient that it tapers toward the display section 2a and that the tip makes point contact with the outer periphery of the display section 2a.

[0098] Furthermore, in this embodiment, the number of first protrusions 25 is described as eight, but the number of first protrusions in this embodiment is not limited to eight, and may be any number, provided that it is one or more.

[0099] The label sheet 20 of this embodiment has a display area 2a displaying information W1 and an outer frame area 2b arranged separately from the display area 2a so as to cover the periphery of the display area 2a. The label sheet 20 is also provided with a sheet body 2 having an adhesive layer 9 on one surface, and a release sheet 23 removably attached to the adhesive layer 9 on the opposite side of the sheet body 2 with the adhesive layer 9 in between. The release sheet 23 is separated into an inner area 23a and an outer area 23b within the area of ​​the outer frame area 2b. The outer area 23b of the release sheet 23 has eight first protrusions 25 extending toward the display area 2a of the sheet body 2. This increases the adhesive strength of the label sheet 20 after the outer area 23a of the release sheet 23 is peeled off but before the inner area 23a of the release sheet 23 is peeled off without increasing the overall size of the label sheet 20. The display area 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display area 2a.

[0100] Furthermore, according to the label sheet 20 of this embodiment, the tip portions 25ac of the eight first protrusions 25 are in contact with the outer periphery of the display portion 2a in a planar view, which further increases the adhesive strength of the label sheet 20 after the outer portion 23b of the release sheet 23 is peeled off but before the inner portion 23a of the release sheet 23 is peeled off, and the display portion 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display portion 2a.

[0101] Furthermore, according to the label sheet 20 of this embodiment, the width of the eight first protrusions 25 narrows toward the display portion 2a, and the tip portions 25ac of the eight first protrusions 25 are in point contact with the outer periphery of the display portion 2a in a planar view. This makes it possible to more reliably peel the display portion 2a from the sheet body 2 while the adhesive layer 9 is firmly held on the display portion 2a.

[0102] Furthermore, the label sheet 20 of this embodiment comprises a sheet body 2 having a substantially rectangular display area 2a displaying information W1 and an outer frame area 2b arranged separately from the display area 2a so as to cover the periphery of the display area 2a, the sheet body 2 having an adhesive layer 9 on one surface, and a release sheet 23 removably attached to the adhesive layer 9 on the opposite side of the sheet body 2 with the adhesive layer 9 in between. The release sheet 23 is separated into an inner portion 23a and an outer portion 23b within the area of ​​the outer frame area 2b, and the outer portion 23b of the release sheet 23 is formed intermittently along the substantially rectangular sides of the display area 2a and has eight first protrusions 25 extending toward the display area 2a of the sheet body 2. This increases the adhesive strength of the label sheet 20 after the outer portion 23b of the release sheet 23 is peeled off but before the inner portion 23a of the release sheet 23 is peeled off without increasing the overall size of the label sheet 20, and the display area 2a can be reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display area 2a.

[0103] Furthermore, according to the label sheet 20 of this embodiment, the eight first protrusions 25 are formed excluding the four corner regions 28 extending radially from the approximately rectangular corners of the display portion 2a. This allows the display portion 2a to be more reliably peeled off from the sheet body 2 while the adhesive layer 9 is firmly held on the display portion 2a, without increasing the overall size of the label sheet 10.

[0104] (Fourth embodiment) Next, a fourth embodiment of the present invention will be described. Note that the drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0105] The fourth embodiment of the present invention will be described below. However, the figures illustrating the operation of peeling the outer portion of the release sheet from the label sheet, the figure showing the label sheet affixed to the substrate after the outer portion of the release sheet has been peeled from the label sheet, and the figure showing the label sheet affixed to the substrate after the display portion has been peeled off are the same as those in Figures 3 to 8, and therefore will not be described here.

[0106] The label sheet 30 of the fourth embodiment differs from the label sheet 1 of the first embodiment in the shape of the display area. That is, while the display area 2a in the first embodiment was generally rectangular, the display area of ​​this embodiment is generally oval.

[0107] FIG. 11 is a plan view of a label sheet according to the fourth embodiment, and FIG. 12 is a rear view of the label sheet according to the fourth embodiment.

[0108] As shown in Figures 11 and 12, the label sheet 30 of this embodiment is also made of paper, resin, or a mixture of paper and resin, and is composed of a sheet body 32 that is generally rectangular in plan view, an adhesive layer 9 (see Figures 3 to 8) provided on one side (back side) of the sheet body 32, and a release sheet 33 that is generally rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32, with the adhesive layer 9 in between.

[0109] The sheet body 32 is made of paper, resin, or a mixture of paper and resin, and has an approximately oval display section 32a on which information W2 such as the product name and manufacturing number is displayed, and an outer frame section 32b that covers the periphery of the display section 32a and is separated from the display section 32a by a front boundary line 34. As mentioned above, an adhesive layer 9 is applied to the entire one side (back side) of the sheet body 32.

[0110] The release sheet 33 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 from the adhesive layer 9, and has the same shape as the sheet body 32, being approximately rectangular in plan view.

[0111] Furthermore, within the outer frame portion 32b of the sheet body 32, the release sheet 33 has an outer portion 33b separated by the back boundary line 37 and located outside the back boundary line 37, and an inner portion 33a also separated by the back boundary line 37 and located inside the back boundary line 37.

[0112] In addition, the outer portion 33b of the peel-off sheet 33 is provided with six first protrusions 35 (35a, 35b, 35c, 35d, 35e and 35f (corresponding to the "protrusions" of the present invention)) that are formed intermittently along the approximately elliptical circumference of the display portion 32a and extend toward the display portion 32a of the sheet main body 32.

[0113] In addition, in this embodiment, in order to make it easier to peel off both ends of the approximately elliptical display section 32a from the sheet body 32, the six first protrusions 35 are not formed in the end regions 38 (38a and 38b) extending radially from the two ends of the approximately elliptical shape of the display section 32a.

[0114] Next, how to use the label sheet 30 described above will be described with reference to the drawings.

[0115] When using the label sheet 30, first, as shown in Figures 3 and 6, the outer portion 33b of the release sheet 33 is peeled off from the label sheet 30 while leaving the inner portion 33a of the release sheet 33 in place, and then the label sheet 30 from which the outer portion 33b has been peeled off is attached to a package P containing a container for an item, as shown in Figures 4 and 7.

[0116] In this case, the six first protrusions 35 create portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the horizontal direction, and portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the vertical direction (see Figures 4, 7 and 12), thereby increasing the adhesive strength of the label sheet 30 after the outer portion 33b of the release sheet 33 is peeled off and before the inner portion 33a of the release sheet 33 is peeled off.

[0117] Thereafter, as shown in Figures 5 and 8, the display portion 32a is peeled off from the label sheet 30 and attached to another item. However, in order for the peeled display portion 32a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 32a must be peeled off from the label sheet 30 with the adhesive layer 9a firmly held on the display portion 32a.

[0118] In the label sheet 30 of this embodiment, even though six first protrusions 35 are present, after the outer portion 33b of the release sheet 33 is peeled off and before the inner portion 33a of the release sheet 33 is peeled off, there is a width in both the horizontal and vertical directions of the adhesive layer 9 attached from the outer periphery of the display portion 32a to the outer periphery of the inner portion 33a.

[0119] Therefore, since all of the adhesive layer 9 applied to the back surface of the display portion 32a is located on the upper surface of the inner portion 33a, not on the packaging body P (see Figures 4, 7, 11 and 12), the adhesive layer 9 is easily peeled off from the inner portion 33a, and the display portion 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9a is firmly held on the display portion 32a.

[0120] In this embodiment, the shape of the six first protrusions 35 has been described as being approximately triangular and tapering toward the display unit 32a. However, the first protrusions of this embodiment are not limited to being approximately triangular, and may be polygonal, such as approximately rectangular, or curved, such as approximately semicircular or approximately semi-elliptical. Even if the shape does not fall within the categories of polygonal or curved, it is sufficient as long as it protrudes toward the display unit 32a.

[0121] Furthermore, in this embodiment, the number of first protrusions 35 is described as six, but the number of first protrusions in this embodiment is not limited to six, and may be any number, provided that it is one or more.

[0122] The label sheet 30 of this embodiment comprises a display area 32a displaying information W2 and an outer frame 32b arranged separately from the display area 32a so as to cover the periphery of the display area 32a. The label sheet 30 is also provided with a sheet body 32 having an adhesive layer 9 on one surface, and a release sheet 33 removably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 in between. The release sheet 33 is separated into an inner portion 33a and an outer portion 33b within the area of ​​the outer frame 32b. The outer portion 33b of the release sheet 33 has six first protrusions 35 extending toward the display area 32a of the sheet body 32. This increases the adhesive strength of the label sheet 30 after the outer portion 33a of the release sheet 33 is peeled off but before the inner portion 33a of the release sheet 33 is peeled off without increasing the overall size of the label sheet 30. Furthermore, the display area 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display area 32a.

[0123] Furthermore, the label sheet 30 of this embodiment includes a sheet body 32 having a substantially oval display area 32a on which information W2 is displayed, and an outer frame area 32b arranged separately from the display area 32a so as to cover the outer periphery of the display area 32a. The sheet body 32 has an adhesive layer 9 on one surface. The release sheet 33 is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 sandwiched therebetween. The release sheet 33 is separated into an inner area 33a and an outer area 33b within the area of ​​the outer frame area 32b. The outer area 33b of the release sheet 33 is the area where the display area 32a is displayed. The label sheet 30 has six first protrusions 35 formed intermittently along the circumference of the approximately elliptical shape of the display portion 32a and extending toward the display portion 32a of the sheet body 32. This increases the adhesive strength of the label sheet 30 after the outer portion 33b of the release sheet 33 is peeled off and before the inner portion 33a of the release sheet 33 is peeled off, without increasing the overall size of the label sheet 30, and allows the display portion 32a to be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0124] Furthermore, according to the label sheet 30 of this embodiment, the six first protrusions 35 are formed excluding two end regions 38 extending radially from both ends of the approximately elliptical shape of the display section 32a. This allows the display section 32a to be more reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display section 32a, without increasing the overall size of the label sheet 30.

[0125] (Fifth embodiment) Next, a fifth embodiment of the present invention will be described. The drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0126] The fifth embodiment of the present invention will be described below. The plan view of the label sheet is the same as that shown in FIG. 11, and therefore its description will be omitted. The figures explaining the operation of peeling the outer portion of the release sheet from the label sheet, the figure showing the label sheet affixed to a substrate after the outer portion of the release sheet has been peeled from the label sheet, and the figure showing the label sheet affixed to the substrate after the display portion has been peeled off are the same as those shown in FIGS. 3 to 8, and therefore their description will be omitted. Parts common to the fourth embodiment will be assigned the same reference numerals and their description will be omitted.

[0127] The label sheet 40 of the fifth embodiment has a different shape for the outer and inner parts compared to the label sheet 30 of the fourth embodiment. That is, in the fourth embodiment, the six first protrusions 35 extending toward the display area 32a of the sheet body 32 did not contact the outer periphery of the planar display area 32a, but the first protrusions of this embodiment do contact the outer periphery of the planar display area.

[0128] FIG. 13 is a rear view of the label sheet of the fifth embodiment.

[0129] As shown in FIG. 13, the label sheet 40 of this embodiment is also made of a paper material, a resin material, or a mixture of paper and resin materials, and is composed of a sheet body 32 that is generally rectangular in plan view, an adhesive layer 9 (see FIGS. 3 to 8) provided on one side (back side) of the sheet body 32, and a release sheet 43 that is generally rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32, with the adhesive layer 9 in between.

[0130] The release sheet 43 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 from the adhesive layer 9, and has the same shape as the sheet body 32, being approximately rectangular in plan view.

[0131] Furthermore, within the outer frame portion 32b of the sheet main body 32, the release sheet 43 has an outer portion 43b separated by the back boundary line 47 and located outside the back boundary line 47, and an inner portion 43a also separated by the back boundary line 47 and located inside the back boundary line 47.

[0132] In addition, the outer portion 43b of the peel-off sheet 43 is provided with eight first protrusions 45 (45a, 45b, 45c, 45d, 45e, 45f, 45g and 45h (corresponding to the "protrusions" of the present invention)) that are formed intermittently along the approximately elliptical circumference of the display portion 32a and extend toward the display portion 32a of the sheet main body 32.

[0133] Furthermore, since the eight first protrusions 45 in this embodiment are located on the opposite side of the sheet main body 32 across the adhesive layer 9, they do not directly contact the outer periphery of the display section 32a. However, as shown in FIG. 13, in a planar view, the tip ends 45ac, 45bc, 45cc, 45dc, 45ec, 45fc, 45gc and 45hc (hereinafter referred to as "45ac, etc.") of the eight first protrusions 45 contact the outer periphery of the display section 32a.

[0134] In addition, in this embodiment, in order to make it easier to peel off both ends of the approximately elliptical display section 32a from the sheet body 32, the eight first protrusions 45 are not formed in the two end regions 48 (48a and 48b) extending radially from the two ends of the approximately elliptical shape of the display section 32a.

[0135] On the other hand, as described above, the inner portion 43a of the release sheet 43 is located inside the rear boundary line 47, but in this embodiment, the tip portions 45ac etc. of the eight first protrusions 45 are in contact with the outer periphery of the display section 32a in a planar view, and therefore the eight second protrusions 46 (46a, 46b, 46c, 46d, 46e, 46f, 46g and 46h) have a shape that protrudes outward from the outer periphery of the display section 32a.

[0136] Note that the eight second protrusions 46 do not all have the same shape. As shown in FIG. 13, the second protrusions 46b, 46c, 46d, 46f, 46g, and 46h have substantially the same rectangular shape, and 46a and 46e include two end regions 48 extending radially from the two ends of the substantially elliptical shape of the display unit 32a, and are larger in shape than the second protrusions 46b, 46c, 46d, 46f, 46g, and 46h.

[0137] When using the label sheet 40, as shown in Figures 3 and 6, first, the outer portion 43b of the release sheet 43 is peeled off from the label sheet 40 while leaving the inner portion 43a of the release sheet 43 in place, and then the label sheet 40 from which the outer portion 43b has been peeled off is attached to a package P including a container for an item, as shown in Figures 4 and 7.

[0138] In this case, the eight first protrusions 45 create portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the horizontal direction, and portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the vertical direction (see Figures 4, 7 and 13), thereby increasing the adhesive strength of the label sheet 40 after the outer portion 43b of the release sheet 43 is peeled off and before the inner portion 43a of the release sheet 43 is peeled off.

[0139] Thereafter, as shown in Figures 5 and 8, the display portion 32a is peeled off from the label sheet 40 and attached to another item. However, in order for the peeled display portion 32a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 32a must be peeled off from the label sheet 30 with the adhesive layer 9a firmly held on the display portion 32a.

[0140] In the label sheet 40 of this embodiment, due to the eight second protrusions 46, after the outer portion 43b of the release sheet 43 is peeled off and before the inner portion 43a of the release sheet 43 is peeled off, there is a horizontal and vertical area of ​​the adhesive layer 9 applied from the outer periphery of the display portion 42a to the outer periphery of the inner portion 43a (see Figure 13).

[0141] Therefore, after the outer portion 43b of the release sheet 43 is peeled off and before the inner portion 43a of the release sheet 43 is peeled off, the adhesive layer 9 located on the upper surface of the inner portion 43a covers the entire display portion 32a and has eight second protrusions 46 (see Figure 13), so the adhesive layer 9 is easily peeled off from the inner portion 43a, and the display portion 32a can be reliably peeled off from the sheet main body 32 while the adhesive layer 9a is firmly held on the display portion 32a.

[0142] In this embodiment, the shape of the eight first protrusions 45 has been described as being approximately rectangular facing the display unit 32a, but the first protrusions of this embodiment are not limited to being approximately rectangular, and may be polygonal, or curved shapes such as approximately semicircular and approximately semi-elliptical.Even if the shape is not included in these polygonal and curved shapes, it is sufficient as long as it protrudes toward the display unit 32a and its tip contacts the outer periphery of the display unit 32a.

[0143] Furthermore, in this embodiment, the number of first protrusions 45 is described as eight, but the number of first protrusions in this embodiment is not limited to eight, and may be any number, provided that it is one or more.

[0144] The label sheet 40 of this embodiment comprises a sheet body 32 having a display area 32a displaying information W2 and an outer frame area 32b arranged separately from the display area 32a so as to cover the periphery of the display area 32a, the sheet body 32 having an adhesive layer 9 on one surface, and a release sheet 43 removably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 in between. The release sheet 43 is separated into an inner portion 43a and an outer portion 43b within the area of ​​the outer frame area 32b, and the outer portion 43b of the release sheet 43 has eight first protrusions 45 extending toward the display area 32a of the sheet body 32. This increases the adhesive strength of the label sheet 40 after the outer portion 43a of the release sheet 43 is peeled off but before the inner portion 43a of the release sheet 43 is peeled off without increasing the overall size of the label sheet 40, and the display area 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display area 32a.

[0145] Furthermore, according to the label sheet 40 of this embodiment, the tip portions 45ac of the eight first protrusions 45 are in contact with the outer periphery of the display portion 32a in a planar view, which further increases the adhesive strength of the label sheet 40 after the outer portion 43b of the release sheet 43 is peeled off but before the inner portion 43a of the release sheet 43 is peeled off, and the display portion 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0146] Furthermore, the label sheet 40 of this embodiment includes a sheet body 32 having a substantially elliptical display area 32a on which information W2 is displayed, and an outer frame area 32b arranged separately from the display area 32a so as to cover the outer periphery of the display area 32a. The sheet body 32 has an adhesive layer 9 on one surface. The release sheet 43 is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 sandwiched therebetween. The release sheet 43 is separated into an inner portion 43a and an outer portion 43b within the area of ​​the outer frame area 32b. The outer portion 43b of the release sheet 43 is a sheet body 32 having an adhesive layer 9 on one surface. The label sheet 40 has eight first protrusions 45 formed intermittently along the approximately elliptical circumference of the display portion 32a of the sheet body 32 and extending toward the display portion 32a of the sheet body 32. This increases the adhesive strength of the label sheet 40 after the outer portion 43b of the release sheet 43 is peeled off and before the inner portion 43a of the release sheet 43 is peeled off, without increasing the overall size of the label sheet 40, and also makes it possible to reliably peel the display portion 32a from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0147] Furthermore, according to the label sheet 40 of this embodiment, the eight first protrusions 45 are formed excluding two end regions 48 extending radially from both ends of the approximately elliptical shape of the display section 32a. This allows the display section 32a to be more reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display section 32a, without increasing the overall size of the label sheet 40.

[0148] (Sixth embodiment) Next, a sixth embodiment of the present invention will be described. Note that the drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0149] The sixth embodiment of the present invention will be described below. The plan view of the label sheet is the same as that shown in FIG. 11, and therefore its description will be omitted. The figures explaining the operation of peeling the outer portion of the release sheet from the label sheet, the figure showing the label sheet affixed to a substrate after the outer portion of the release sheet has been peeled from the label sheet, and the figure showing the label sheet affixed to the substrate after the display portion has been peeled off are the same as those shown in FIGS. 3 to 8, and therefore their description will be omitted. Parts common to the fourth embodiment will be assigned the same reference numerals, and their description will be omitted.

[0150] The label sheet 50 of the sixth embodiment has a different shape of the outer and inner parts compared to the label sheet 30 of the fourth embodiment. That is, in the fourth embodiment, the six first protrusions 35 extending toward the display area 32a of the sheet body 32 did not contact the outer periphery of the planar display area 32a, but the first protrusions of this embodiment make point contact with the outer periphery of the planar display area.

[0151] FIG. 14 is a rear view of the label sheet of the sixth embodiment.

[0152] As shown in FIG. 14, the label sheet 50 of this embodiment is also made of a paper material, a resin material, or a mixture of paper and resin materials, and is composed of a sheet body 32 that is generally rectangular in plan view, an adhesive layer 9 (see FIGS. 3 to 8) provided on one side (back side) of the sheet body 32, and a release sheet 53 that is generally rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32, with the adhesive layer 9 in between.

[0153] The release sheet 53 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 from the adhesive layer 9, and has the same shape as the sheet body 32, being approximately rectangular in plan view.

[0154] Furthermore, within the outer frame portion 32b of the sheet main body 32, the release sheet 53 has an outer portion 53b separated by the back boundary line 57 and located outside the back boundary line 57, and an inner portion 53a also separated by the back boundary line 57 and located inside the back boundary line 57.

[0155] In addition, the outer portion 53b of the peel-off sheet 53 is provided with six first protrusions 55 (55a, 55b, 55c, 55d, 55e and 55f (corresponding to the "protrusions" of the present invention)) which are formed intermittently along the approximately elliptical circumference of the display portion 32a and which are gradually tapered toward the display portion 32a of the sheet main body 32.

[0156] Furthermore, since the six first protrusions 55 in this embodiment are located on the opposite side of the sheet main body 32 across the adhesive layer 9, they do not come into direct contact with the outer periphery of the display section 32a. However, as shown in FIG. 14, in a planar view, the tips 55ac, 55bc, 55cc, 55dc, 55ec and 55fc (hereinafter referred to as "55ac, etc.") of the six first protrusions 55 come into point contact with the outer periphery of the display section 32a.

[0157] In addition, in this embodiment, in order to make it easier to peel off both ends of the approximately elliptical display section 32a from the sheet main body 32, the six first protrusions 55 are not formed in the two end regions 58 (58a and 58b) extending radially from the two ends of the approximately elliptical shape of the display section 32a.

[0158] On the other hand, as described above, the inner portion 53a of the peel-off sheet 53 is located inside the rear boundary line 57, but in this embodiment, the tip portions 55ac etc. of the six first protrusions 55 are in point contact with the outer periphery of the display section 32a in a planar view, and therefore the six second protrusions 56 (56a, 56b, 56c, 56d, 56e and 56f) have a shape that protrudes outward from the outer periphery of the display section 32a.

[0159] Note that the six second protrusions 56 do not all have the same shape; as shown in FIG. 14, the second protrusions 56b, 56c, 56e, and 56f are all approximately trapezoidal in shape, and 56a and 56d are sized to include two end regions 58 extending radially from the two ends of the approximately elliptical shape of the display unit 32a.

[0160] When using the label sheet 50, as shown in Figures 3 and 6, first, the outer portion 53b of the release sheet 53 is peeled off from the label sheet 50 while leaving the inner portion 53a of the release sheet 53 in place, and then the label sheet 50 from which the outer portion 53b has been peeled off is attached to a package P including a container for an item, as shown in Figures 4 and 7.

[0161] In this case, the six first protrusions 55 create portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the horizontal direction, and portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the vertical direction (see Figures 4, 7 and 14), thereby increasing the adhesive strength of the label sheet 50 after the outer portion 53b of the release sheet 53 is peeled off and before the inner portion 53a of the release sheet 53 is peeled off.

[0162] Thereafter, as shown in Figures 5 and 8, the display portion 32a is peeled off from the label sheet 50 and attached to another item. However, in order for the peeled display portion 32a to be attached to another item, the adhesive layer 9 must be separated into the peeled adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 32a must be peeled off from the label sheet 30 with the adhesive layer 9a firmly held on the display portion 32a.

[0163] In the label sheet 50 of this embodiment, due to the six second protrusions 56, after the outer portion 53b of the release sheet 53 is peeled off and before the inner portion 53a of the release sheet 53 is peeled off, there is a horizontal and vertical area of ​​the adhesive layer 9 applied from the outer periphery of the display portion 32a to the outer periphery of the inner portion 53a (see Figure 14).

[0164] Therefore, after the outer portion 53b of the release sheet 53 is peeled off and before the inner portion 53a of the release sheet 53 is peeled off, the adhesive layer 9 located on the upper surface of the inner portion 53a covers the entire display portion 32a and has six second protrusions 56 (see Figure 14), so the adhesive layer 9 is easily peeled off from the inner portion 53a, and the display portion 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9a is firmly held on the display portion 32a.

[0165] In this embodiment, the shape of the six first protrusions 55 has been described as being gradually tapered toward the display section 32a of the seat main body 32, but the first protrusions of this embodiment are not limited to such a shape and may be an approximately polygonal shape, or a curved shape such as an approximately semicircular shape or an approximately semi-elliptical shape.Even if the shape is not included in these polygonal shapes or curved shapes, it is sufficient that it tapers toward the display section 32a and that its tip makes point contact with the outer periphery of the display section 32a.

[0166] Furthermore, in this embodiment, the number of first protrusions 55 is described as six, but the number of first protrusions in this embodiment is not limited to six, and may be any number, provided that it is one or more.

[0167] The label sheet 50 of this embodiment comprises a sheet body 32 having a display area 32a displaying information W2 and an outer frame area 32b arranged separately from the display area 32a so as to cover the periphery of the display area 32a, the sheet body 32 having an adhesive layer 9 on one surface, and a release sheet 53 removably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 in between. The release sheet 53 is separated into an inner portion 53a and an outer portion 53b within the area of ​​the outer frame area 32b, and the outer portion 53b of the release sheet 53 has six first protrusions 55 extending toward the display area 32a of the sheet body 32. This increases the adhesive strength of the label sheet 50 after the outer portion 53a of the release sheet 53 is peeled off but before the inner portion 53a of the release sheet 53 is peeled off without increasing the overall size of the label sheet 50, and the display area 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display area 32a.

[0168] Furthermore, according to the label sheet 50 of this embodiment, the tip portions 55ac of the six first protrusions 55 are in contact with the outer periphery of the display portion 32a when viewed in a plane, which further increases the adhesive strength of the label sheet 50 after the outer portion 53b of the release sheet 53 is peeled off but before the inner portion 53a of the release sheet 53 is peeled off, and the display portion 32a can be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0169] Furthermore, according to the label sheet 50 of this embodiment, the width of the six first protrusions 55 narrows toward the display portion 32a, and the tip portions 55ac of the six first protrusions 55 are in point contact with the outer periphery of the display portion 32a in a planar view, so that the display portion 32a can be more reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0170] Furthermore, the label sheet 50 of this embodiment includes a sheet body 32 having a substantially elliptical display area 32a displaying information W2 and an outer frame area 32b arranged separately from the display area 32a so as to cover the outer periphery of the display area 32a, and the sheet body 32 is provided with an adhesive layer 9 on one surface, and a release sheet 53 separated into an inner portion 53a and an outer portion 53b within the area of ​​the outer frame area 32b, the release sheet 53 being releasably attached to the adhesive layer 9 on the opposite side of the sheet body 32 with the adhesive layer 9 interposed therebetween. The label sheet 50 has six first protrusions 55 formed intermittently along the approximately elliptical circumference of the display portion 32a and extending toward the display portion 32a of the sheet body 32. This increases the adhesive strength of the label sheet 50 after the outer portion 53b of the release sheet 53 is peeled off and before the inner portion 53a of the release sheet 53 is peeled off, without increasing the overall size of the label sheet 50, and allows the display portion 32a to be reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display portion 32a.

[0171] Furthermore, according to the label sheet 50 of this embodiment, the six first protrusions 55 are formed excluding two end regions 58 extending radially from both ends of the approximately elliptical shape of the display section 32a. This allows the display section 32a to be more reliably peeled off from the sheet body 32 while the adhesive layer 9 is firmly held on the display section 32a, without increasing the overall size of the label sheet 50.

[0172] (Seventh embodiment) Next, a seventh embodiment of the present invention will be described. Note that the drawings used in this embodiment are also exaggerated to facilitate understanding, and the dimensions are different from the actual dimensions.

[0173] The seventh embodiment of the present invention will be described below. However, the figures explaining the operation of peeling the outer portion of the release sheet from the label sheet, the figure showing the label sheet attached to the substrate after the outer portion of the release sheet has been peeled from the label sheet, and the figure showing the label sheet attached to the substrate after the display portion has been peeled off are the same as those in Figures 3 to 8, and therefore will not be described here.

[0174] The label sheet 60 of the seventh embodiment differs from the label sheets of the above-described embodiments in the number of display areas. That is, whereas the above-described embodiments had one display area, this embodiment has multiple display areas.

[0175] FIG. 15 is a plan view of the label sheet of the seventh embodiment, and FIG. 16 is a rear view of the label sheet of the seventh embodiment.

[0176] As shown in Figures 15 and 16, the label sheet 60 of this embodiment is also made of paper material, resin material, or a material that is a mixture of paper material and resin material, and is composed of a sheet body 62 that is approximately rectangular in plan view, an adhesive layer 9 (see Figures 3 to 8) provided on one side (back side) of the sheet body 62, and a release sheet 63 that is approximately rectangular in plan view and releasably attached to the adhesive layer 9 on the opposite side of the sheet body 62, with the adhesive layer 9 in between.

[0177] The sheet main body 62 is made of paper, resin, or a mixture of paper and resin, and is equipped with: a substantially rectangular display section 62aa on which information W3a (W3) such as the product name and serial number is displayed; a substantially rectangular display section 62ab located adjacent to the right side of the display section 62aa on which information W3b (W3) such as the product name and serial number is displayed; a substantially rectangular display section 62ac located adjacent to the right side of the display section 62ab on which information W3c (W3) such as the product name and serial number is displayed; a substantially rectangular display section 62ad located adjacent to the right side of the display section 62ac on which information W3d (W3) such as the product name and serial number is displayed; and a substantially rectangular display section 62ae located adjacent to the right side of the display section 62ad on which information W3e (W3) such as the product name and serial number is displayed.

[0178] In addition, the sheet main body 62 has an outer frame portion 62b that covers the outer peripheries of the display portions 62aa, 62ab, 62ac, 62ad and 62ae (hereinafter referred to as "display portion 62aa, etc.") and is separated from these display portions by a front boundary line 64 (64a, 64b, 64c, 64d and 64e), and as mentioned above, an adhesive layer 9 is applied to the entire one side (rear side) of the sheet main body 62.

[0179] The release sheet 63 is made of a paper material, a resin material, or a material that is a mixture of paper and resin materials, and as described above, is releasably attached to the adhesive layer 9 on the opposite side of the sheet body 62 from the adhesive layer 9, and has the same shape as the sheet body 62, being approximately rectangular in plan view.

[0180] Furthermore, within the outer frame portion 62b of the sheet main body 62, the release sheet 63 has an outer portion 63b separated by the back boundary line 67 and located outside the back boundary line 67, and an inner portion 63a also separated by the back boundary line 67 and located inside the back boundary line 67.

[0181] In addition, the outer portion 63b of the release sheet 63 is provided with a total of 14 first protrusions 65 (65a, 65b, 65c, 65d, 65e, 65f, 65g, 65h, 65j, 65k, 65m, 65n, 65p and 65q (corresponding to the "protrusions" of the present invention)) which are formed intermittently along the entire outer periphery of the display portion 62aa, etc. and which are gradually tapered toward the display portion 62aa, etc., and have an approximately semicircular shape.

[0182] Furthermore, since the 14 first protrusions 65 in this embodiment are located on the opposite side of the sheet main body 62 across the adhesive layer 9, they do not come into direct contact with the outer periphery of the display section 62a, etc. However, as shown in Figures 15 and 16, in plan view, a total of 14 tip portions 65ac, 65bc, 65cc, 65dc, 65ec, 65fc, 65gc, 65hc, 65jc, 65kc, 65mc, 65nc, 65pc and 65qc (hereinafter referred to as "65ac, etc.") of the first protrusions 65 come into point contact with the outer periphery of the display section 62a.

[0183] In addition, in this embodiment, in order to make it easier to peel off the corners of the approximately rectangular display section 62a, etc. from the sheet main body 62, the 14 first protrusions 65 are not formed in the 12 corner regions 68 (68a, 68b, 68c, 68d, 68e, 68f, 68g, 68h, 68j, 68k, 68m and 68n) extending radially from the 12 approximately rectangular corners of the display section 62aa, etc.

[0184] On the other hand, as described above, the inner portion 63a of the peel-off sheet 63 is located inside the rear boundary line 67, but in this embodiment, the tip portions 65ac etc. of the 14 first protrusions 65 are in point contact with the outer periphery of the display section 62a in a planar view, and therefore the 14 second protrusions 66 (66a, 66b, 66c, 66d, 66e, 66f, 66g, 66h, 66j, 66k, 66m, 66n, 66p and 66q) have a shape that protrudes outward from the outer periphery of the display section 62a.

[0185] Note that the 14 second protrusions 66 do not all have the same shape; as shown in FIG. 16, second protrusions 66b, 66c, 66d, 66e, 66g, 66j, 66k, 66m, 66n and 66q are all approximately trapezoidal in shape, and 66a, 66f, 66h and 66p are shaped to include four corner regions 68a, 68f, 68g and 68n extending radially from the four corners of the approximately rectangular shape of the entire display unit 62a, etc.

[0186] When using the label sheet 60, first, as shown in Figures 3 and 6, the outer portion 63b of the release sheet 63 is peeled off from the label sheet 60 while leaving the inner portion 63a of the release sheet 63 in place, and then the label sheet 60 from which the outer portion 63b has been peeled off is attached to a package P including a container for an item, as shown in Figures 4 and 7.

[0187] In this case, the 14 first protrusions 65 create portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the horizontal direction, and portions in which the adhesive layer 9 attached to the packaging body P has a longer width in the vertical direction (see Figures 4, 7, 15 and 16), thereby increasing the adhesive strength of the label sheet 60 after the outer portion 63b of the release sheet 63 is peeled off and before the inner portion 63a of the release sheet 63 is peeled off.

[0188] Thereafter, as shown in Figures 5 and 8, the selected display portion 62a, etc. is peeled off from the label sheet 60 and attached to another item. However, in order for the peeled off display portion 62a, etc. to be attached to another item, the adhesive layer 9 must be separated into the peeled off adhesive layer 9a and the adhesive layer 9b that remains on the packaging body P, and the display portion 62a, etc. must be peeled off from the label sheet 60 with the adhesive layer 9a firmly held on the display portion 62a, etc.

[0189] In the label sheet 60 of this embodiment, due to the 14 second protrusions 66, after the outer portion 63b of the release sheet 63 is peeled off and before the inner portion 63a of the release sheet 63 is peeled off, there is a horizontal and vertical area of ​​the adhesive layer 9 applied from the outer periphery of the display portion 62a, etc. to the outer periphery of the inner portion 63a (see Figures 15 and 16).

[0190] Therefore, after the outer portion 63b of the release sheet 63 is peeled off and before the inner portion 63a of the release sheet 63 is peeled off, the adhesive layer 9 located on the upper surface of the inner portion 63a covers the entire display portion 62a, etc., and has 14 second protrusions 66 (see Figures 15 and 16), so the adhesive layer 9 is easily peeled off from the inner portion 63a, and each display portion 62a, etc. can be reliably peeled off from the sheet main body 62 while the adhesive layer 9a is firmly held on the display portion 62a, etc.

[0191] In this embodiment, the shape of the 14 first protrusions 65 has been described as being approximately semicircular, gradually tapering toward the entire display section 62a, etc. of the seat main body 62. However, the first protrusions of this embodiment are not limited to such a shape, and may be curved shapes such as approximately polygonal shapes and approximately semi-elliptical shapes. Even if the shape is not included in these polygonal and curved shapes, it is sufficient as long as it tapers toward the display section 62a, etc. and has a shape that makes point contact with the outer periphery of the display section 62a, etc.

[0192] Furthermore, in this embodiment, the number of first protrusions 65 is described as 14, but the number of first protrusions in this embodiment is not limited to 14, and may be any number, provided that it is one or more.

[0193] Furthermore, in this embodiment, five display sections 62a and the like are provided on the label sheet 60, but the number of display sections in this embodiment is not limited to five, and any label sheet may be provided with a plurality of display sections.

[0194] The label sheet 60 of this embodiment comprises a sheet body 62 having a display area 62a, etc. displaying information W3, and an outer frame area 62b arranged separately from the display area 62a, etc. so as to cover the entire periphery of the display area 2a, etc., and is provided with an adhesive layer 9 on one surface; and a release sheet 63, which is removably attached to the adhesive layer 9 on the opposite side of the sheet body 62 with the adhesive layer 9 in between, and which is separated into an inner area 63a and an outer area 63b within the area of ​​the outer frame area 62b. The outer area 63b of the release sheet 63 has fourteen first protrusions 65 extending toward the entire display area 62a, etc. of the sheet body 62. This increases the adhesive strength of the label sheet 60 after the outer area 63a of the release sheet 63 is peeled off but before the inner area 63a of the release sheet 63 is peeled off without increasing the overall size of the label sheet 60, and allows the selected display area 62a, etc. to be reliably peeled off from the sheet body 62 while the adhesive layer 9 is firmly held on the display area 62a, etc.

[0195] Furthermore, according to the label sheet 60 of this embodiment, the tip portions 65ac etc. of the 14 first protrusions 65 are in contact with the outer periphery of the entire display portion 62a etc. when viewed in a plane, which further increases the adhesive strength of the label sheet 60 after the outer portion 63b of the peel-off sheet 63 is peeled off but before the inner portion 63a of the peel-off sheet 63 is peeled off, and the selected display portion 62a etc. can be reliably peeled off from the sheet body 62 while the adhesive layer 9 is firmly held on the display portion 62a etc.

[0196] Furthermore, according to the label sheet 60 of this embodiment, the width of the 14 first protrusions 65 narrows toward the entire display section 62a, and the tip portions 65ac etc. of the 14 first protrusions 65 are in point contact with the outer periphery of the display section 62a etc. when viewed in a plane. This allows the selected display section 62a etc. to be more reliably peeled off from the sheet body 62 while the adhesive layer 9 is firmly held on the display section 62a etc.

[0197] Furthermore, the label sheet 60 of this embodiment includes a sheet body 62 having a substantially rectangular display area 62a etc. on which information W3 is displayed, and an outer frame area 62b arranged separately from the display area 62a so as to cover the outer periphery of the display area 62a etc., and the sheet body 62 has an adhesive layer 9 on one surface, and a release sheet 63 separated into an inner portion 63a and an outer portion 63b within the area of ​​the outer frame area 62b, the release sheet 63 being releasably attached to the adhesive layer 9 on the opposite side of the sheet body 62 with the adhesive layer 9 in between. The outer portion 63b of the release sheet 63 is separated into an inner portion 63a and an outer portion 63b within the area of ​​the outer frame area 62b, and the outer portion 63b of the release sheet 63 is separated from the display area 62a etc. The label sheet 60 is provided with 14 first protrusions 65 formed intermittently along the periphery of the overall, approximately rectangular shape and extending toward the display portion 62a, etc. of the sheet body 62. This increases the adhesive strength of the label sheet 60 after the outer portion 63b of the release sheet 63 is peeled off and before the inner portion 63a of the release sheet 63 is peeled off without increasing the overall size of the label sheet 60, and allows the selected display portion 62a, etc. to be reliably peeled off from the sheet body 62 while the adhesive layer 9 is firmly held on the display portion 62a, etc.

[0198] Furthermore, according to the label sheet 60 of this embodiment, the 14 first protrusions 65 are formed excluding the 12 corner regions 68 extending radially from the 12 approximately rectangular corners of the display section 62a, etc., so that the selected display section 62a, etc. can be more reliably peeled off from the sheet body 62 while the adhesive layer 9 is firmly held on the display section 62a, etc., without increasing the overall size of the label sheet 60.

[0199] The label sheets of various embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and can be modified and implemented in various ways without departing from the spirit of the present invention.

[0200] For example, the provision of multiple display areas, as in the label sheet 60 of the seventh embodiment, can be applied to the label sheets of the first to sixth embodiments. [Explanation of symbols]
