Summary of the Invention

Problems to be Solved by the Invention

[0004] When trying to open the lid portion of the flap label to take out the contents of the container, the open lid portion tends to close due to the elastic force of the lid portion. To prevent this, the lid portion is opened and supported with one hand, and during that time, the contents are taken out from the opening of the container with the other hand. However, for example, when only one hand can be used, the removal operation may be hindered when the open lid portion closes by itself.

[0005] Therefore, the present invention aims to provide a flap label that can maintain an open lid position without external support when the lid is opened. [Means for solving the problem]

[0006] To achieve the above objective, the flap label according to the present invention has a first surface and a second surface which are front and back sides of each other, and the first surface has a fold that forms a valley, and has a first region, a second region and a third region arranged in this order, in which the first region has a first adhesive layer exposed on at least a part of the first surface, in the third region has a second adhesive layer exposed on at least a part of the first surface, the adhesive strength of the first adhesive layer is stronger than the adhesive strength of the second region, the adhesive strength of the second adhesive layer is stronger than the adhesive strength of the second region, the fold overlaps the boundary line between the first region and the second region or crosses the second region, and the boundary line between the second region and the third region includes a portion that protrudes toward the first region in the middle. [Effects of the Invention]

[0007] According to the present invention, when the lid is opened, it can maintain the open position without external support. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] (Embodiment 1) (composition) Referring to Figures 1 to 4, a flap label in Embodiment 1 of the present invention will be described. First, Figure 1 shows a plan view of the flap label 101 in this embodiment. The flap label 101 is mainly made using, for example, a resin sheet. Figure 2 shows a cross-sectional view taken along the line II-II in Figure 1. Figure 3 shows an example of the state in which the flap label 101 is used. In Figure 3, product 501 is shown. Product 501 includes a bag 20 and a flap label 101. The bag 20 has a top surface 23, a front surface 24, and a back surface 25. The bag 20 has ends 21 and 22. The flap label 101 is attached so as to span the top surface 23 and the back surface 25 of the bag 20. Product 501 shown in Figure 3 is in an unopened state.

[0010] As shown in Figure 1, the flap label 101 has a first surface 11 and a second surface 12 that are opposite each other. The flap label 101 has a fold line 2 on the first surface 11 side, which is the valley. Figure 1 shows the state before folding at fold line 2, but fold line 2 is prepared so that the first surface 11 side is the valley and the second surface 12 side is the peak. In the example shown here, fold line 2 has perforations to make it easier to fold. However, fold line 2 does not necessarily have perforations, and the state of being easy to fold may be achieved by other means. For example, another sheet with a crease may be attached to this part.

[0011] The flap label 101 has a first region 41, a second region 42, and a third region 43 arranged in this order. That is, the second region 42 is positioned between the first region 41 and the third region 43. A boundary line 51 exists between the first region 41 and the second region 42. In the example shown in Figure 1, the boundary line 51 is a straight line, but this is just one example. The boundary line 51 may be other than a straight line. A boundary line 52 exists between the first region 42 and the second region 43. In the example shown here, the boundary line 52 is a broken line. The boundary line 52 includes a first line portion 71 and a second line portion 72. The first line portion 71 and the second line portion 72 are symmetrical. Furthermore, the boundary line 52 includes a portion 75 that protrudes toward the first region 41 between the first line portion 71 and the second line portion 72. In this example, the portion 75 is V-shaped.

[0012] The second region 42 includes part 42a and part 42b. Part 42a and part 42b are distinguished by a fold 2. Part 42a is the part that is attached to the top surface 23 of the bag 20. Part 42b is the part that is attached to the back surface 25 of the bag 20.

[0013] As shown in Figure 2, the flap label 101 includes an upper base material 3 and a lower base material 4. The material of the upper base material 3 may be, for example, polypropylene (PP), polyethylene terephthalate (PET), or paper. The thickness of the upper base material 3 may be, for example, 20 μm or more and 120 μm or less. The thickness of the upper base material 3 may be, for example, 20 μm, 40 μm, or 50 μm. The material of the lower base material 4 may be, for example, polypropylene (PP), polyethylene terephthalate (PET), or paper. The thickness of the lower base material 4 may be, for example, 50 μm or more and 150 μm or less. The thickness of the lower base material 4 may be, for example, 100 μm, 75 μm, or 50 μm. The types and thicknesses of materials listed here are merely examples, and other materials may also be used. The term "paper" here may be, for example, art paper, coated paper, or poly-laminated paper.

[0014] As shown in Figure 2, in the first region 41, the first adhesive layer 61 is exposed on at least a portion of the first surface 11 side. In the third region 43, the second adhesive layer 62 is exposed on at least a portion of the first surface 11 side. In the second region 42, the adhesive layer 65 is exposed on the first surface 11 side. Here, as an example, the second region 42 has an adhesive layer 65, but the adhesive layer 65 may or may not be present.

[0015] The adhesive strength of the first adhesive layer 61 is stronger than the adhesive strength of the second region 42. The adhesive strength of the second adhesive layer 62 is stronger than the adhesive strength of the second region 42. Here, we are comparing adhesive strengths, but this does not necessarily mean that there is an adhesive layer in the second region 42. When comparing adhesive strengths, if there is no adhesive layer in the second region 42, the adhesive strength of the second region 42 should be considered as 0 for comparison. If there is an adhesive layer 65 in the second region 42, the adhesive strength of the adhesive layer 65 will be used for comparison. The adhesive layer 65 may be formed by creating the same material as the first adhesive layer 61 and then applying some treatment to this layer to reduce its adhesive strength. Alternatively, the adhesive layer 65 may be coated with a different type of adhesive than the first adhesive layer 61.

[0016] The adhesive strength of the first adhesive layer 61 and the adhesive strength of the second adhesive layer 62 may be equal or different. The first region 41 is the lid portion. That is, the first adhesive layer 61 is for repeated attachment and detachment to the bag 20. The second adhesive layer 62 is for the third region 43, which is to remain permanently attached to the bag 20. Therefore, it is preferable that the adhesive strength of the second adhesive layer 62 is stronger than that of the first adhesive layer 61. In order to prevent the third region 43 from peeling off the bag 20 when the user peels off the first region 41 when opening the product 501, it is preferable that the adhesive strength of the second adhesive layer 62 is sufficiently strong.

[0017] In Figure 1, the dashed line with the leader line "2" represents a perforation provided in at least a portion of fold 2. As shown in Figure 1, fold 2 may include a section without perforations. Fold 2 continues even in the section without perforations. Here, as shown in Figure 2, the perforations in fold 2 create cuts in the lower base material 4, but not in the upper base material 3. Therefore, there are no perforations in the third region 43 where the lower base material 4 has been removed.

[0018] Fold 2 includes the section to the left of section 75 and the section to the right of section 75 in Figure 1. In other words, fold 2 includes "two sections".

[0019] Fold 2 either coincides with the boundary line 51 between the first region 41 and the second region 42, or crosses the second region 42. In the example shown in Figure 1, fold 2 crosses the second region 42. When fold 2 crosses the second region 42, the entire fold 2 is not necessarily inside the second region 42; as shown in Figure 1, a part of fold 2 may pass through a region other than the second region 42.

[0020] In the example shown in Figure 1, the boundary line 52 between the second region 42 and the third region 43 includes a portion that intersects with the fold line 2. This is merely one example. The boundary line 52 includes a portion that protrudes toward the first region 41. "Includes a portion that protrudes toward..." has a broad meaning as follows: A configuration in which there is a portion that locally protrudes toward the first region 41, as in portion 75 in Figure 1, naturally falls under the category of "includes a portion that protrudes toward the first region 41." Furthermore, even without a localized protruding portion, a configuration in which the boundary line 52 has an inverted V-shape, a curved shape, etc., and one of the points in the middle of the boundary line 52 is closer to the first region 41 than both ends of the boundary line 52 also falls under the category of "includes a portion that protrudes toward the first region 41."

[0021] The flap label 101 includes a handle portion 1. Here, a portion of the first region 41 forms the handle portion 1, but this is merely an example. The handle portion 1 may be provided outside the first region 41. As shown in Figure 2, in the handle portion 1, an adhesive layer 66 is provided on the first surface 11 side instead of the first adhesive layer 61. The adhesive strength of the adhesive layer 66 is weaker than that of the first adhesive layer 61. The adhesive layer 66 may be formed by creating the same material as the first adhesive layer 61 and then applying some treatment to reduce its adhesive strength. Alternatively, the adhesive layer 66 may be coated with a different type of adhesive than the first adhesive layer 61. Alternatively, the adhesive layer 66 may not be provided, and the handle portion 1 may have no adhesive layer on the first surface 11 side.

[0022] Figure 2 shows a cross-sectional view of the flap label 101. However, to obtain such a product, unused flap labels 101 may be supplied with portion 5 attached, as shown in Figure 4. In this case, the user can peel off portion 5 from the flap label 101 and then attach the flap label 101 to the bag 20. In this way, product 501 can be obtained.

[0023] (Effects / Actions) In this embodiment, since the above-described configuration is provided, when the lid is opened, it can maintain the open position without external support.

[0024] This action will be explained in detail below. First, Figure 5 shows the process of opening the first region 41, which serves as the lid portion of the flap label 101. In Figure 5, the product 501 is viewed from a different side than in Figure 3. To open the lid portion, the user simply needs to hold the tab 1 and pull in the direction of the arrow 91. In Figure 5, the opening 26 of the bag 20 is exposed. The portion 27, which was part of the bag 20, has separated from the top surface 23 of the bag 20 and is lifted up together with the first region 41. The portion 27 is attached to the first region 41.

[0025] After the first region 41, which serves as the lid, has completely detached from the top surface 23, the portion 42a of the second region 42 also detaches from the top surface 23. When the angle that the first region 41 makes with respect to the top surface 23 exceeds 90° and the lid has opened to a certain extent, releasing the hand pulling the knob 1 results in the state shown in Figure 6. That is, the first region 41 and the second region 42 are bent over and become self-supporting. Figure 7 shows this state from a different angle. Figure 8 shows this state viewed from directly above. Figure 9 shows the view in the direction of arrow 92 in Figure 7. In this state, the lid can maintain its open position without external support.

[0026] In this state, the first region 41 and the second region 42 are detached from the bag body 20, and at this time, the third region 43 remains attached to the back surface 25 of the bag body 20. In this state, the two sections of the fold 2 described above each maintain a straight line. In this state, as shown in Figures 6 to 8, the two sections of the fold 2 are not on a straight line, but form a V-shape with a large central angle. The directions in which the two sections of the fold 2 extend intersect in the direction in which the lid portion stands upright. The two sections of the fold 2 act as bones to maintain the posture of the first region 41 and the second region 42.

[0027] As shown in Figure 9, the angle that the first region 41 makes with respect to the top surface 23 is already greater than 90°. The gravitational force based on the weight of the first region 41 acts in the direction of arrow 93 in Figure 9, so the first region 41 can maintain an upright position without falling towards the top surface 23. When the lid is upright in this way, the magnitude of the angle that the lid makes with respect to the top surface 23 at which it becomes stable depends on the thickness of the flap label material, etc.

[0028] As shown in this embodiment, the boundary line 52 between the second region 42 and the third region 43 preferably includes a first line portion 71 and a second line portion 72 arranged symmetrically with respect to each other, and each of the first line portion 71 and the second line portion 72 is inclined to approach the first region 41 as it moves from the end of the boundary line 52 toward the center. By adopting this configuration, the vertical dimension of the second region 42 increases the further it is from the center, so that when the lid is opened, the second region 42 can move further away from the back surface 25 the further it is from the center. Therefore, the second region 42 can bend back significantly, and the lid can stand stably on its own.

[0029] As shown in this embodiment, it is preferable that the boundary line 52 between the second region 42 and the third region 43 includes a portion 75 that protrudes toward the first region 41 compared to the first line portion 71 and the second line portion 72. By adopting this configuration, the lid portion can stand stably on its own.

[0030] In the example shown in this embodiment, a portion of the third region 43 protrudes beyond the fold 2 toward the first region 41, so that, as shown in Figure 3, a portion of the third region 43 overlaps the top surface 23 of the bag 20. It is preferable that a portion of the third region 43 overlaps the top surface 23 of the bag 20. Alternatively, it is also preferable that a portion of the third region 43 is in contact with the top surface 23 of the bag 20, even if it does not overlap the top surface 23 of the bag 20. In other words, it is preferable that the boundary line 52 between the second region 42 and the third region 43 is in contact with the fold 2 or includes a portion that intersects with the fold 2. By adopting this configuration, the lid portion can stand stably on its own.

[0031] It is not essential that a portion of the third region 43 overlaps with or touches the top surface 23 of the bag 20. For example, the upper edge of the third region 43 may be lower than the fold 2. That is, the upper edge of the third region 43 may be located on the back surface 25 without reaching the top surface 23. In other words, the boundary line 52 between the second region 42 and the third region 43 does not have to touch the fold 2.

[0032] As shown in this embodiment, the flap label includes an upper base material 3 and a lower base material 4, with the upper base material 3 exposed on the second surface 12. The first region 41 and the second region 42 have a structure of at least four layers: the upper base material 3, the second adhesive layer 62, the lower base material 4, and the first adhesive layer 61. The third region 43 has a structure of at least two layers: the upper base material 3 and the second adhesive layer 62. This configuration is preferable because it facilitates the manufacture of the flap label and makes handling the flap label easier when in use.

[0033] Thus, by preparing the first adhesive layer 61 and the second adhesive layer 62 as layers located at different heights, and peeling off the member covering one of the layers, a configuration can be obtained in which the first adhesive layer 61 is exposed in the first region 41 and the second adhesive layer 62 is exposed in the third region 43. Alternatively, as a different approach, for example, a configuration may be obtained in which different adhesives are applied to the first region 41 and the third region 43 on the same surface of the same layer. Alternatively, the same type of adhesive may be applied to the first region 41 and the third region 43, and a treatment may be applied to the first region 41 to reduce the adhesive strength of the adhesive.

[0034] (Several variations) In Embodiment 1, an example was shown in which the boundary line 52 between the second region 42 and the third region 43 intersects the fold 2, and in which a particularly protruding portion 75 of the boundary line 52 intersects the fold 2. However, other configurations are also possible, such as the flap label 102 shown in Figure 10. In the flap label 102, the boundary line 52 includes a protruding portion 75i. The portion 75i is V-shaped, but its central angle is different from that of the portion 75 shown in Embodiment 1. In the flap label 102, the fold 2 is in contact with the lower end of the portion 75i. That is, the fold 2 is positioned to pass through the boundary between the first line portion 71 and the second line portion 72 and the portion 75i. Similar effects can be obtained even with such a configuration.

[0035] Furthermore, other shapes of the protruding portion are also possible. For example, in the flap label 103 shown in Figure 11, the boundary line 52 includes portion 75j. Portion 75j is curved. Portion 75j may be a circular arc or another type of curve. In the flap label 103, the fold 2 is in contact with the lower end of portion 75j. The fold 2 may be positioned to intersect portion 75j.

[0036] In the flap label 104 shown in Figure 12, the boundary line 52 includes portion 75k. Portion 75j is folded twice at right angles. Therefore, the area enclosed by portion 75k is rectangular. In the flap label 104, fold 2 is in contact with the lower edge of portion 75k. Fold 2 may be positioned to intersect portion 75k.

[0037] (Embodiment 2) (composition) Referring to Figure 13, the flap label in Embodiment 2 of the present invention will be described. Figure 13 shows a plan view of the flap label 105 in this embodiment. The configuration of the flap label 105 is basically the same as that described in Embodiment 1, but differs in the following points.

[0038] In the flap label 105, the boundary line 52 includes the first line portion 71 and the second line portion 72, but does not include any portions protruding from them. The boundary line 52 as a whole has a V-shape. The fold line 2 intersects the boundary line 52.

[0039] (Effects / Actions) In this embodiment as well, the same effects as in Embodiment 1 can be obtained.

[0040] As a variation of the flap label 105, a flap label 106 like the one shown in Figure 14 can also be considered. In the flap label 106, the boundary line 52 includes the first line portion 71 and the second line portion 72, but does not include any portions protruding from them. In the flap label 106, the fold line 2 is positioned to be in contact with the boundary line 52. The fold line 2 does not intersect the boundary line 52. The same effects as in the first embodiment can be obtained with a flap label 106 with this configuration.

[0041] (Embodiment 3) (composition) Referring to Figure 15, the flap label in Embodiment 3 of the present invention will be described. Figure 15 shows a plan view of the flap label 107 in this embodiment. The configuration of the flap label 107 is basically the same as that of the flap label 106 described as a modification in Embodiment 2, but differs in the following points.

[0042] In the flap label 107, the boundary line 52 includes a first line portion 71r and a second line portion 72r. The first line portion 71r and the second line portion 72r are curved. The boundary line 52 as a whole has a curved shape.

[0043] (Effects / Actions) In this embodiment as well, the same effects as in Embodiment 1 can be obtained. In the flap label 107, the boundary line 52 does not include portions that protrude from the first line portion 71r and the second line portion 72r, but it may include portions that protrude. In the flap label 107, the boundary line 52 is only in contact with the fold line 2 and does not intersect it, but it may intersect the fold line 2.

[0044] (Embodiment 4) (composition) Referring to Figure 16, the flap label in Embodiment 4 of the present invention will be described. Figure 16 shows a plan view of the flap label 108 in this embodiment. The configuration of the flap label 108 is basically the same as that of the flap label 101 described in Embodiment 1, but differs in the following points.

[0045] In the flap label 108, the first line portion 71 and the second line portion 72 included in the boundary line 52 are aligned in a straight line. The first line portion 71 and the second line portion 72 are parallel to the boundary line 51. The boundary line 52 includes a protruding portion 75. The portion 75 intersects with the fold line 2.

[0046] (Effects / Actions) In this embodiment as well, the same effects as in Embodiment 1 can be obtained.

[0047] As a variation of the flap label 108, a flap label 109, as shown in Figure 17, is also conceivable. In the flap label 109, the boundary line 52 does not intersect with the fold line 2, but is in contact with the fold line 2. The upper end of the protruding portion 75 included in the boundary line 52 is in contact with the fold line 2.

[0048] (Snack section) The shape of the knob portion 1 will now be described. This applies to all embodiments.

[0049] The knob portion 1 may be part of the first region 41, or it may be provided separately from the first region 41. The knob portion 1 may be provided so as to protrude from the portion forming the first region 41 in some shape. The shape of the protruding knob portion 1 may be, for example, a trapezoid, a semicircle, a triangle, etc. The outer shape of the lid portion may be curved. The lid portion may have a configuration such as that shown in Figure 18.

[0050] (Embodiment 5) (composition) Referring to Figures 19 to 20, the flap label in Embodiment 5 of the present invention will be described. Figure 19 shows a plan view of the flap label 110 in this embodiment. The configuration of the flap label 110 is basically the same as that of the flap label 101 described in Embodiment 1, but differs in the following points.

[0051] The flap label 110 includes a peripheral edge 44. The peripheral edge 44 is positioned to surround the first region 41 and the second region 42 from above and from the left and right in Figure 19. The peripheral edge 44 is connected to the third region 43.

[0052] Figure 20 shows an example of the use of the flap label 110. In this example, the flap label 110 is attached to the bag 20, and the first region 41 acts as the lid. Figure 20 shows the flap label 110 in the process of being opened. When peeling off the lid, the peripheral edge 44 remains attached to the top surface 23 of the bag 20. The first region 41 and the second region 42 are lifted, leaving the peripheral edge 44 on the top surface 23.

[0053] (Effects / Actions) In this embodiment as well, the same effects as in Embodiment 1 can be obtained.

[0054] As a first modification of the flap label 110, a flap label 111 like the one shown in Figure 21 can also be considered. In the flap label 111, the peripheral edge 44 is not located on the upper side of the first region 41 in the figure, but is positioned along the left and right sides of the first region 41 and the second region 42.

[0055] A second variation of the flap label 110 is the flap label 112 shown in Figure 22. In the flap label 112, the peripheral edge 44 is positioned to surround the first region 41 and the second region 42 from above and the left and right in Figure 22, but the peripheral edge 44 is interrupted because the handle portion 1 is positioned to cross the peripheral edge 44. The end of the handle portion 1 reaches the outline of the flap label 112.

[0056] These modifications also provide the same effects as the flap label 110 in Embodiment 5.

[0057] (Embodiment 6) (composition) Referring to Figure 23, the flap label in Embodiment 6 of the present invention will be described. Figure 23 shows a plan view of the flap label 113 in this embodiment. The configuration of the flap label 113 is basically the same as that described in Embodiment 1, but differs in the following points.

[0058] In the flap label 113, notches 45 are provided at positions corresponding to both ends of the fold 2. In the example shown in Figure 23, the notches 45 are semicircular, but this is just one example. The notches may have other shapes. It is preferable that the notches have a rounded shape.

[0059] (Effects / Actions) In this embodiment as well, the same effects as in Embodiment 1 can be obtained. Furthermore, in this embodiment, since notches 45 are provided at both ends of the fold 2, when the flap label 113 is folded along the fold 2 and attached to the bag body 20, the positions of both ends of the fold 2 are closer to the center compared to when there are no notches 45. This prevents the corners of the folded fold 2 from becoming sharp, and reduces the degree to which the user feels pain from the corners of the fold 2.

[0060] As shown in Figure 23, the creation of the notch 45 results in new corners in the outline of the flap label 113. It is preferable to round off these newly created corners (not shown).

[0061] (Embodiment 7) (composition) Referring to Figures 24 to 28, the flap label in Embodiment 7 according to the present invention will be described. A plan view of the flap label 114 in this embodiment is shown in Figure 24. A cross-sectional view taken along the line XXV-XXV in Figure 24 is shown in Figure 25. An example of the state in which the flap label 114 is used is shown in Figure 26. In Figure 26, product 502 is shown. Product 502 includes a bag 20 and a flap label 114. The basic configuration of the flap label 114 is the same as that described in Embodiment 1, but differs in several respects.

[0062] In the flap label 114, a residue portion 46 is provided inside the first region 41. Further inside the residue portion 46, a portion 47 corresponding to the opening 26 of the bag body 20 is provided. The portion 47 may be made of the same material as the residue portion 46. The portion 47 is not part of the residue portion 46. The residue portion 46 is ring-shaped and surrounds the portion 47. The flap label 114 includes a printed layer 6 placed on the upper surface of the base material 4. The printed layer 6 is a layer of ink printed on the upper surface of the base material 4. The outline of the residue portion 46 when viewed in plan is, for example, approximately rectangular. Along the outline of the residue portion 46 when viewed in plan, cuts are made in the thickness direction across the first adhesive layer 61, the base material 4, and the printed layer 6. Furthermore, along the outline of the portion 47 inside the residue portion 46 when viewed in plan, cuts are made in the thickness direction across the first adhesive layer 61, the base material 4, and the printed layer 6. A silicone ink layer 7 is positioned on the upper surface of the residual portion 46 so as to cover the printed layer 6. The silicone ink layer 7 is in contact with the second adhesive layer 62, but due to the properties of the silicone ink layer 7, it can be easily peeled off from the second adhesive layer 62.

[0063] Figure 27 shows the process of opening the first region 41, which serves as the lid portion of the flap label 114. In Figure 27, the product 502 is viewed from a different side than in Figure 26. Here, the user is holding the tab 1 and pulling in the direction of the arrow 91. In Figure 27, a gap 48 is visible on the first surface 11 of the first region 41. The gap 48 is the mark left by the removal of the residual portion 46. The first surface 11 is indented at the gap 48. That is, the first region 41 is thinner at the gap 48. The portion 27, which was originally part of the upper surface 31 of the bag body 20, is lifted up while remaining attached to the first surface 11 of the first region 41. Although the portion 47 is not clearly visible in Figure 27, it is sandwiched between the portion 27 and the first region 41. The portion 27 is held in place by the action of the first adhesive layer 61 of the portion 47. The opening 26 of the bag body 20 is visible in the center of the residual portion 46. Here, section 47, section 27, and opening 26 are shown as being of the same shape and size, but in reality, section 47 may be set to be somewhat larger or smaller than opening 26 to accommodate errors.

[0064] When the user holds the knob 1 and pulls in the direction of arrow 91, the entire first region 41, which serves as the lid, peels off from the top surface 23, and then the portion 42a of the second region 42 also peels off from the top surface 23. When the angle that the first region 41 makes with respect to the top surface 23 exceeds 90° and the knob 1 is released, the state shown in Figure 28 is achieved. That is, the first region 41 and the second region 42 bend backward and become self-supporting.

[0065] Regarding the flap label 114, the following can be said. When the first region 41 is peeled off the object while at least a part of the first region 41 is attached to the object by the first adhesive layer 61, the part inside the first region 41 that is exposed as part of the first surface 11 can be peeled off from the part of the first region 41 other than the residue portion 46 as a residue portion 46 that remains on the surface of the object, and the residue portion 46 can be repeatedly attached to and peeled off from the part of the first region 41 other than the residue portion 46. The object referred to here is, for example, a bag 20. In Figure 26, the first region 41 is attached to the top surface 23 of the bag 20. The third region 43 is attached to the back surface 25 of the bag 20.

[0066] (Effects / Actions) In this embodiment, since it has the above-described configuration, the same effects as in Embodiment 1 can be obtained. Furthermore, when the first region 41, which serves as the lid, is opened, the residual portion 46 remains on the surface of the object, thus stabilizing the shape of the upper surface of the object. In other words, the upper surface of the object is reinforced by the residual portion 46, making it easier to maintain a flat state.

[0067] In this embodiment, the residual portion 46 is supplied as part of the first region 41 of the flap label 114, so the entire flap label 114, including the residual portion 46, can be treated as a single sheet-like article before use, which is convenient.

[0068] Preferably, the residual portion 46 has an opening for removing the contents contained in the object. In this embodiment, the opening that remains in the residual portion 46 as a result of the removal of portion 47 is the opening for removing the contents contained in the object.

[0069] (Embodiment 8) (composition) Referring to Figures 29 to 37, the flap label in Embodiment 8 of the present invention will be described. Figure 29 shows a plan view of the flap label element 115, which is part of the flap label in this embodiment. Furthermore, Figure 30 shows a plan view of the residual portion 15, which is part of the flap label in this embodiment. Figure 31 shows a cross-sectional view of the flap label element 115. Figure 32 shows a cross-sectional view of the residual portion 15. The flap label element 115 does not include the residual portion 15. The flap label element 115 includes a printed layer 6. The printed layer 6 is located between the second adhesive layer 62 and the base material 4. The printed layer 6 is a layer of ink printed on the surface of the base material 4. The residual portion 15 exists as a separate component from the flap label element 115. The residual portion 15 includes the residual portion base material 8 and the adhesive layer 67.

[0070] Figure 33 shows a cross-sectional view of the flap label 116 with the flap label element 115 and the residual portion 15 combined. The residual portion 15 is attached to the first surface 11 of the flap label element 115 using the first adhesive layer 61 that is exposed on the first surface 11.

[0071] The flap label element 115 alone may be considered as a single flap label, but in this embodiment, the set including both the flap label element 115 and the residual portion 15 is considered as a single flap label 116. The residual portion 15 includes an opening corresponding portion 16. A member may be present in the opening corresponding portion 16 in its pre-use state. The member in the opening corresponding portion 16 may be removed immediately before use of the residual portion 15. In that case, the residual portion 15 will be, for example, an annular shape with an opening. The shape of the residual portion 15 is not limited to annular. The shape of the residual portion 15 may be, for example, U-shaped, C-shaped, or the like. In the unused state of the flap label 116, the flap label 116 may be provided as an integrated unit with the residual portion 15 attached to the flap label element 115. In the unused state of the flap label 116, the residual portion 15, which is part of the flap label 116, may be provided as an independent sheet separate from the flap label element 115. A silicone ink layer 7 is placed on the surface of the residual portion 15. The silicone ink layer 7 may be formed by printing.

[0072] Figure 34 shows an example of how the flap label 116 is used. In Figure 34, product 503 is shown. Product 503 includes a bag 20 and a flap label 116. The flap label 116 includes a flap label element 115 and a residue portion 15. The residue portion 15 is hidden behind the flap label element 115.

[0073] Figure 35 shows the process of opening the first region 41, which serves as the lid portion of the flap label 116. In Figure 35, the product 503 is viewed from a different side than in Figure 34. Here, the user is holding the handle 1 and pulling in the direction of arrow 91. After the entire first region 41, which serves as the lid portion, has peeled off from the top surface 23, the portion 42a of the second region 42 also peels off from the top surface 23. When the angle that the first region 41 makes with respect to the top surface 23 exceeds 90° and the hand pulling the handle 1 is released, the state shown in Figure 36 is achieved. That is, the first region 41 and the second region 42 bend backward and become self-supporting.

[0074] Figure 37 shows a schematic cross-sectional view of the first region 41, which serves as the lid, in this state. For the sake of explanation, the entire structure in Figure 37 has been corrected to appear parallel. For the sake of explanation, a portion of the bag body 20 is also shown in Figure 37. The portion 27, which was originally part of the bag body 20, is held in place by the adhesive layer 67 of the opening corresponding portion 16 and is lifted up together with the lid.

[0075] With regard to the flap label 116, which is conceived as a combination of the flap label element 115 and the residual portion 15, the following can be said.

[0076] The flap label 116 includes a residual portion 15, which is a component provided separately from the first region 41. When the first region 41 is peeled off from an object while at least a portion of the first region 41 is attached to the object by the first adhesive layer 61, the residual portion 15 can be repeatedly attached to and peeled off the area exposed on the first surface 11 of the first adhesive layer 61.

[0077] (Effects / Actions) In this embodiment, since the above-described configuration is provided, the same effects as in Embodiment 7 can be obtained. In this embodiment, since the residual portion 15 is provided separately from the first region 41, the first region 41 does not become thinner even when the first region 41, which acts as a lid, is opened. Therefore, the shape of the first region 41 is stable when the first region 41 and the second region 42 are bent over and stand on their own.

[0078] (Preferred angle) Referring to Figure 38, the preferred angle of portion 75 of boundary line 52 will be described. Figure 38 is an enlarged plan view of portion 75 and its vicinity in Figure 24. In the example shown here, portion 75 is V-shaped and forms an angle α. In order for the first region 41, which serves as the lid portion, to open and stand on its own, the angle α is preferably between 50° and 120°. If the angle α is less than 50°, the first region 41, which serves as the lid portion, will have difficulty standing on its own. Also, if the angle α exceeds 120°, the first region 41, which serves as the lid portion, will have difficulty standing on its own.

[0079] Angle α is more preferably 60° or more and 110° or less. Furthermore, angle α is more preferably 80° or more and 100° or less. Angle α is preferably approximately 90°. Angle α may be 90°. Part 75 may be pointed or rounded. Part 75 is preferably pointed. Even if the tip of part 75 is not completely pointed but rounded, the above preferred conditions apply to the angle formed by the two sides of part 75.

[0080] From the information disclosed so far, we can understand, for example, the following flap labels.

[0081] (Note A) The flap label described above, wherein when the first region is peeled off from the object while at least a portion of the first region is attached to the object by the first adhesive layer, a portion inside the first region that is exposed as part of the first surface can be peeled off from the portion of the first region other than the residue portion as a residue portion that remains on the surface of the object, and the residue portion can be repeatedly attached to and peeled off from the portion of the first region other than the residue portion.

[0082] (Note B) The remaining portion is a component provided separately from the first region, The flap label described above, wherein when the first region is peeled off from the object while at least a portion of the first region is attached to the object by the first adhesive layer, the remaining portion can be repeatedly attached to and peeled off the area exposed on the first surface of the first adhesive layer.

[0083] (Note C) The residual portion is the flap label described above, having an opening for removing the contents contained in the object.

[0084] Furthermore, multiple embodiments of the above-described model may be combined and adopted as appropriate. The embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims and includes all modifications in the sense and scope equivalent to the claims. [Explanation of Symbols]
