Description

Technical Field

[0001] The present invention relates to labels.

Background Art

[0002] In recent years, there are cases where labels are provided on the upper part of cans for promotion. For example, in Patent Document 1, there is disclosed a label made of cardboard having a size larger than the upper lid of the can, and two arcuate cut lines are provided at two opposing locations outside the region covering the upper lid to form bending regions, and a claw portion is defined in the middle of each bent region by a part of the cut line.

[0003] The above label is disclosed to be attached to the upper part of the can by bending each bending region downward when placed on the upper part of the can to project the claw portions facing inward, and hooking the claw portions on the outside (rib) of the edge on the upper lid.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when the claw portion of the above label is hooked and attached to a can with a shallow rib, since the rib is shallow, the claw portion of the above label is not sufficiently hooked on the above rib. Therefore, when an external force is applied to the above label during transportation of the can or filling of the can at the store, the claw portion of the above label may come off the above rib immediately.

[0006] Also, when the claw portion of the above label is hooked and attached to a can with a deep rib, when an external force is applied to the above label during transportation of the can or filling of the can at the store, the claw portion of the above label may come off the above rib.

[0007] One aspect of the present invention aims to provide a label that can be stably fixed to the top of a can. [Means for solving the problem]

[0008] To solve the above problems, a label according to one aspect of the present invention is a label fixed to the upper surface of a can provided with a tab, wherein the tab has a tension portion that is pulled when the can is opened, a fixing portion that is fixed to the upper surface of the can, and a connecting portion that extends from the tension portion at a distance from the can and connects the tension portion and the fixing portion, wherein, when the label is fixed to the upper surface of the can, a notch is formed which has at least a bulging portion that bulges out in the direction toward the tab from the outer peripheral edge of the upper surface, and the notch forms a first locking piece that is inserted below the connecting portion and locks between the tab and the upper surface. [Effects of the Invention]

[0009] According to one aspect of the present invention, a label that can be stably fixed to the top of a can can be provided. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0011] 〔Embodiment 1〕 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 12. In FIGS. 1 to 12, for a configuration that is vertically symmetric or horizontally symmetric with respect to a certain axis, only one of the symmetric configurations is assigned a reference sign, and the assignment of a reference sign to the other configuration is omitted.

[0012] <Main Configuration of Label> FIG. 1 is a view showing a state where a label 1 according to Embodiment 1 is fixed to the upper surface 61 of a can 6 provided with a tab 2.

[0013] In this embodiment, the can 6 is an aluminum beverage can. The material of the can 6 is not particularly limited, and for example, it may be made of steel. The type of the can 6 is not particularly limited, and it may be a can lid with a partial open end such as a beverage can, or may be a full open end can lid of a tuna can such as a food can. In this embodiment, the tab 2 is a stay-on tab type, but it may also be a pull-tab type.

[0014] As shown in FIG. 1, a cut L1 is formed in the label 1. This cut L1 includes at least a bulging portion 7 that bulges in the direction D1 from the outer peripheral edge 62 of the upper surface 61 of the can 6 toward the tab 2 in a state where the label 1 is fixed to the upper surface 61 of the can 6. Note that the direction D1 shown in FIG. 1 is an example, and it is not limited to this as long as it is a direction from the outer peripheral edge 62 of the upper surface of the can 6 toward the tab 2.

[0015] Furthermore, a first locking piece 11 that is locked between the tab 2 and the upper surface 61 of the can 6 is formed in the label 1 by the cut L1. In this embodiment, the first locking piece 11 is locked between one end side in the longitudinal direction of the tab 2 and the upper surface 61 of the can 6. Here, in this specification, the longitudinal direction of the tab 2 refers to the direction passing through the axis of symmetry of the tab 2. One end side in the longitudinal direction of the tab 2 refers to the side of the connecting portion 5 in the longitudinal direction (see FIG. 2). Note that a plurality of first locking pieces 11 may be formed.

[0016] Also, the label 1 includes a second locking piece 12 that is locked to the outside 63 of the outer peripheral edge 62 from the direction D2 opposite to the direction in which the first locking piece 11 exists with respect to the connecting portion 5 in a state where the label 1 is fixed to the upper surface 61 of the can 6. The detailed configuration of the label 1 and the fixing method of the label 1 and the can 6 will be described later.

[0017] <Configuration of the tab> Figure 2 is a top view of a can 6 equipped with the tab 2 shown in Figure 1. The top surface 61 of the can 6 (see Figure 1) is omitted in Figure 2. Figure 3 is a cross-sectional view taken along the line AA in Figure 2. As shown in Figures 2 and 3, the tab 2 has a tensioning portion 3, a fixing portion 4, and a connecting portion 5, and has an insertion hole 21 for inserting a finger. The insertion hole 21 is elliptical when viewed from above.

[0018] The tension portion 3 includes the area where fingers are actually gripped and pulled when opening the can 6. That is, the tension portion 3 is the hook piece 31 on which fingers are gripped when opening the can 6 and the area near it. In this embodiment, the hook piece 31 is the area in the tension portion 3 where a straight line perpendicular to the periphery of the tension portion 3 passes over the top of the fixing portion 4 (the area shown by hatching in Figure 2).

[0019] The fixing portion 4 is the part that is fixed to the upper surface 61 of the can 6. The fixing portion 4 has a first fixing portion 41 and a second fixing portion 42. The first fixing portion 41 is the part that is fixed to the upper surface 61 of the can 6. The second fixing portion 42 is the part of the first fixing portion 41 that extends upward toward the outer peripheral edge 62 of the upper surface 61 of the can 6 from the side opposite to the side where the tension portion 3 exists relative to the first fixing portion 41. The second fixing portion 42 and the upper surface 61 of the can 6 are spaced apart.

[0020] The connecting portion 5 refers to the portion of the tab 2 other than the tension portion 3. That is, the connecting portion 5 extends from the tension portion 3 while being spaced apart from the upper surface 61 of the can 6, and connects the tension portion 3 to the second fixing portion 42. Furthermore, the connecting portion 5 does not include the portion fixed to the upper surface 61 of the can 6. In addition, a hole 51 is formed in the connecting portion 5. The hole 51 is larger than the first fixing portion 41 when viewed from above.

[0021] The first locking piece 11 shown in Figure 1 is inserted from the peripheral edge 22 of the tensioning portion 3, excluding the hooking piece 31, to the underside of the connecting portion 5 when fixing the label 1 to the upper surface 61 of the can 6 on which the tab 2 is provided. The first locking piece 11 shown in Figure 1 is inserted from the peripheral edge 52 of the connecting portion 5 to the underside of the connecting portion 5 when fixing the label 1 to the upper surface 61 of the can 6 on which the tab 2 is provided. This reduces the possibility of the can 6 being accidentally opened by the tab 2 when the first locking piece 11 is inserted into the connecting portion 5.

[0022] In this embodiment, the portion of the first locking piece 11 shown in Figure 1 that is inserted into the connecting portion 5 is the portion of the tension portion 3 that excludes the vicinity of the hooking piece 31 from the peripheral edge 22 that forms the insertion hole 21. As a result, when the first locking piece 11 is inserted into the connecting portion 5, the first locking piece 11 does not come into contact with the hooking piece 31. Therefore, the possibility of the can 6 being accidentally opened by the tab 2 when the first locking piece 11 is inserted into the connecting portion 5 can be further reduced.

[0023] Figure 4 is a top view of tab 2A relating to a modified version of can 6 shown in Figure 1. Figure 5 is a cross-sectional view taken along the line BB in Figure 2. Unlike tab 2, tab 2A is a pull-tab type.

[0024] As shown in Figures 4 and 5, the tab 2A has a tension portion 3A, a fixing portion 4A, and a connecting portion 5A. The tension portion 3A has a larger elliptical insertion hole 21A compared to the insertion hole 21 of the tension portion 3. Unlike the connecting portion 5, the connecting portion 5A is configured such that when viewed from above, its width narrows in the direction perpendicular to the opening and closing direction of the tab 2A toward the fixing portion 4A.

[0025] <Detailed label structure> Figure 6 is an unfolded view of label 1 shown in Figure 1. Label 1 is manufactured by punching out printed cardboard. As shown in Figure 6, when label 1 is fixed to the top surface 61 of can 6 (see Figure 1), four arch-shaped cuts L2, L3, L4, and L5 are formed at approximately equal intervals so as to cover the top surface 61 of can 6 and substantially follow the outer edge 62. The area that covers the top surface 61 of can is referred to as area R1.

[0026] The notches L2, L3, L4, and L5 are for forming the regions R2, R3, R4, and R5, respectively, which are to be folded. Before the label 1 is fixed to the top surface 61 of the can 6, the notches L2, L3, L4, and L5 each have portions that curve in the direction from regions R2, R3, R4, and R5 toward region R1, at approximately the midpoint of the notches. This forms the second locking piece 12, third locking piece 13, fourth locking piece 14, and fifth locking piece 15 that engage with the outside 63 of the outer edge 62 when the label 1 is fixed to the top surface 61 of the can 6.

[0027] Furthermore, as long as the second locking piece 12, the third locking piece 13, the fourth locking piece 14, and the fifth locking piece 15 are configured to lock onto the outer surface 63 of the outer peripheral edge 62, they do not need to be arranged at approximately equal intervals in the circumferential direction of the outer peripheral edge 62.

[0028] The portion of label 1 facing the first locking piece 11 across the notch L1 functions as a protective piece 16 that covers the top surface 61 of can 6. The protective piece 16 refers to the portion on the side of the first locking piece 11 with respect to the straight line passing through both ends of the bulge 7 in region R1. In this embodiment, when label 1 is fixed to the top surface 61 of can 6, the outer circumference of the protective piece 16 overlaps with the outer edge 62 of can 6 or is located outside the outer edge 62. This reduces the possibility of debris entering the top surface 61 of can 6 from outside label 1 through the protective piece 16, thereby protecting the opening of can 6.

[0029] <Structure of the first locking piece> Figure 7 shows the first locking piece 11 formed on the label 1 shown in Figure 1. As shown in Figure 7, the notch L1 has arc-shaped curved portions 8 formed at both ends and a bulge portion 7 in the center. In this embodiment, the bulge portion 7 is also formed in an arc shape. This makes it easier to operate with the thumb or index finger when fixing the label 1 to the top surface 61 of the can 6.

[0030] <Modified example of the first locking piece> Figures 8 to 11 show modified examples of the first locking piece 11 shown in Figure 7. Labels equipped with the first locking pieces 11A, 11B, 11C, 11D, 11E, 11F, 11G, and 11H shown in Figures 8(a), 8(b), 9(a), 9(b), 10(a), 10(b), 11(a), and 11(b) respectively will be referred to as labels 1A, 1B, 1C, 1D, 1E, 1F, 1G, and 1H, respectively.

[0031] As shown in Figure 8(a), the notch LA1 has first straight sections 9 formed at both ends, and the central part is triangular in shape. As a result, the bulge 7A is triangular in shape. Furthermore, the bulge 7A tapers from the outer peripheral edge 62 of the upper surface 61 of the can 6 toward the tab 2, and bulges out so as to touch the first fixing portion 41 at a single point.

[0032] As shown in Figure 8(b), the cut LB1 has a fifth straight section 92 at both ends and a fourth straight section 91 perpendicular to the fifth straight section 92, and a bulge 7B is formed in the central part.

[0033] The bulging portion 7B has two parallel and equal-length second straight sections 71B and a third straight section 72B that linearly connects one end of each of the two second straight sections 71B. In other words, the bulging portion 7B is rectangular in shape.

[0034] Since the bulging portion 7B has a third straight portion 72B, even if the label 1B moves in a direction parallel to the third straight portion 72B due to an external impact or the like, the first locking piece 11B remains in contact with the first fixing portion 41. Therefore, the bulging portion 7B can be kept locked between the tab 2 and the upper surface 61. As a result, the label 1B can be suitably maintained in a state of being fixed to the upper surface 61 of the can 6.

[0035] As shown in Figure 9(a), the notch LC1 has arc-shaped curved portions 8 formed at both ends and a bulge 7C in the central part. Unlike the bulge 7, the bulge 7C has a third straight portion 71C near the first fixing portion 41 that runs along the short direction perpendicular to the longitudinal direction of the tab 2. In other words, the bulge 7C is approximately trapezoidal. Because the notch LC1 with the bulge 7C is formed, the label 1C can be suitably fixed to the upper surface of the can 6, similar to the label 1B.

[0036] As shown in Figure 9(b), the notch LD1 has arc-shaped curved portions 8 formed at both ends and a bulge portion 7D in the center. The bulge portion 7D has a wavy portion 71D that is W-shaped when viewed from above, instead of the third straight portion 71C of the bulge portion 7C. Therefore, even if the label 1D moves in a direction parallel to the short side of the tab 2 due to an external impact or the like, the area in which the first locking piece 11D is locked between the tab 2 and the upper surface 61 of the can 6 can be increased. As a result, the state in which the label 1D is fixed to the upper surface 61 of the can 6 can be suitably maintained.

[0037] Furthermore, the W-shaped wave-like lines formed in the wavy portion 71D are located on one end of the tab 2 in the longitudinal direction, relative to the first fixing portion 41. Therefore, even when the label 1D moves in a direction parallel to the short direction of the tab 2, it does not get caught on the first fixing portion 41, making it easier to remove the label 1D.

[0038] As shown in Figure 10(a), the two notches LE1 have arc-shaped curved portions 8 formed at both ends and an arc-shaped bulge 7E in the central portion. In other words, unlike label 1, label 1E has two first locking pieces 11E. One of the first locking pieces 11E is locked between one end of tab 2 in the shorter direction and the upper surface 61 of can 6. Here, in this specification, one end of tab 2 in the shorter direction refers to the region R3 side (see Figure 6) in the shorter direction when label 1E is fixed to the upper surface 61 of can 6.

[0039] The other first locking piece 11E is locked between the other end of the tab 2 in the shorter direction and the top surface 61 of the can 6. Here, in this specification, the other end of the tab 2 in the shorter direction refers to the region R5 side (see Figure 6) in the shorter direction when the label 1E is fixed to the top surface 61 of the can 6. As a result, even if force is applied to the short side of the tab 2 due to an external impact or the like, the first locking piece 11E can suitably maintain the state in which the tab 2 is locked between the top surface 61 of the can 6.

[0040] As shown in Figure 10(b), the notch LE1 has arc-shaped curved portions 8 formed at both ends and an arc-shaped bulge 7E in the central part. Similarly, the notch LF1 has arc-shaped curved portions 8 formed at both ends and a bulge 7F in the central part. Unlike the bulge 7E, the bulge 7F has a third straight portion 71F that runs along the longitudinal direction of the tab 2 near the first fixing portion 41. In other words, unlike the label 1E, the label 1F has a first locking piece 11E and a first locking piece 11F.

[0041] The first locking piece 11F is locked between one end of the tab 2 in the short direction and the top surface 61 of the can 6. The first locking piece 11E is locked between the other end of the tab 2 in the short direction and the top surface 61 of the can 6.

[0042] As a result, in addition to the effects of label 1E, even when force is applied to label 1F on the longitudinal side of tab 2 due to external impact or the like, label 1F can maintain a state in which the first locking piece 11F corresponding to the third straight portion 71F is in contact with the first fixing portion 41. Therefore, the state in which it is locked between tab 2 and the upper surface 61 of can 6 can be suitably maintained.

[0043] As shown in Figure 11(a), the cut LG1 has an arc-shaped bulge 7G formed in the central part. The figure formed by connecting the bulge 7G and both ends of the bulge 7G with straight lines is semicircular when viewed from above.

[0044] The notch LG1 has curved sections that curve from both ends of the bulging portion 7G toward the tab 2 from the outer peripheral edge 62 of the upper surface 61 of the can 6. Therefore, unlike label 1, label 1H has a hole 17 formed by the notch LH1. This creates a distance between the first locking piece 11G and the protective piece 16, which reduces the possibility of the thumb or index finger coming into contact with the protective piece 16 when fixing label 1G to the upper surface 61 of the can 6, and makes it easier to operate the first locking piece 11G with the thumb or index finger.

[0045] As shown in Figure 11(b), the notch LH1 has first straight sections 9 formed at both ends and a bulge 7H formed in the central part. The bulge 7H has second straight sections 71H that are parallel to each other and of the same length, and a curved section 72H that curves from one end of the two second straight sections 71H so as not to follow at least a part of the first fixing section 41. In other words, the bulge 7H is formed so as not to follow at least a part of the first fixing section 41 and not to surround the entire first fixing section 41. Therefore, when force is applied to the shorter side of the tab 2, the point where the second straight sections 71H and the curved section 72H are connected catches on the first fixing section 41, thus maintaining the label 1H fixed to the top surface of the can 6. In addition, a distance is formed between the first locking piece 11 and the first fixing section 41 in the part that surrounds at least a part of the first fixing section 41, making it easier to remove the label 1 fixed to the top surface 61 of the can 6.

[0046] Furthermore, the bulges (7-7G, 7J) shown in Figures 7-11(a) and 13(b) above can be considered as examples of bulges that do not follow at least a part of the first fixing portion 41 and do not surround the entire first fixing portion 41. For example, a shape that curves toward the opposite side of the first fixing portion 41, as shown in Figure 7 for bulge 7, or a shape that is linear relative to the first fixing portion 41, as shown in Figure 8 for bulges (7A, 7B), can be considered a preferred shape of a bulge that does not follow at least a part of the first fixing portion 41 and does not surround the entire first fixing portion 41.

[0047] Furthermore, if it is desired to improve the ease of removal, for example, to label 1, rather than the label 1H fixed to the top surface 61 of can 6, then the first locking piece 11H should be deformed so that it does not catch on the first fixing part 41 when force is applied to the shorter side of the first locking piece 11H.

[0048] <How to attach a label to a can> Figure 12 illustrates the method for fixing the label 1 shown in Figure 1 to the can 6. Figure 12(a) shows the state before the label 1 shown in Figure 1 is fixed to the can 6. Figure 12(b) shows the state after the notch L1 formed in the label 1 shown in Figure 1 is inserted below the connecting part 5. Figure 12(c) shows the state after the label 1 shown in Figure 1 is fixed to the can 6.

[0049] As shown in Figure 12(a), the label 1 is attached to the top surface 61 or outer edge 62 of the can 6, moving from the top to the bottom. Next, as shown in Figure 12(b), the first locking piece 11 is inserted from the periphery 52 of the connecting part 5 to the underside of the connecting part 5 and locks between the tab 2 and the top surface 61 of the can 6. This allows the label 1 to be stably fixed to the top surface 61 of the can 6.

[0050] Next, as shown in Figure 12(c), each of the folding regions R2, R3, R4, and R5 is folded downward along the notches L2, L3, L4, and L5. The second locking piece 12, the third locking piece 13, the fourth locking piece 14, and the fifth locking piece 15 are brought out and locked to the outside 63 of the outer peripheral edge 62 of the top surface 61 of the can 6. This allows the label 1 to be more stably fixed to the top surface 61 of the can 6. Then, each of the folding regions R2, R3, R4, and R5 is brought into contact with the side surface 64 of the can 6.

[0051] Furthermore, since label 1 can be stably fixed to the top surface 61 of can 6 as long as the first locking piece 11 and the second locking piece 12 are formed, it is not necessary for some or all of the third locking piece 13, the fourth locking piece 14, and the fifth locking piece 15 to be formed.

[0052] [Embodiment 2] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated. Furthermore, the method for fixing label 1I to the can is the same as the method for fixing label 1 to the can, and therefore its description is omitted.

[0053] <Detailed label structure> Figure 13 is an unfolded view of the label 1I according to Embodiment 2 of the present invention. Figure 14 shows the label 1I shown in Figure 13 fixed to the top surface 61 of the can 6. Figure 15 is a top view of the can 6 with the tab 2 shown in Figure 14 provided.

[0054] As shown in Figures 13 to 15, unlike label 1, label 1I has two arch-shaped notches L2 and L4 formed at approximately equal intervals along the outer peripheral edge 62 of the upper surface 61 of can 6 when label 1I is fixed to the upper surface 61 of can 6.

[0055] Unlike region R1, label 1I has region RA1 which covers a portion of the top surface 61 of can 6. In other words, a portion of the outer periphery of region RA1 is located inside the outer edge 62 of can 6.

[0056] As shown in Figure 15, when the label 1I is fixed to the top surface 61 of the can 6, a region R6 is formed on the top surface 61 of the can 6 that is not covered by the label 1I. Region R6 is a region demarcated by the outer peripheral surface of the label 1I and the outer peripheral edge 62 of the top surface 61 of the can 6 when the label 1I is fixed to the top surface 61 of the can 6.

[0057] Furthermore, when fixed to the top surface 61 of the can 6, a portion of the outer periphery of the protective piece 16A is located inside the outer edge 62 of the can 6. In other words, a portion of the outer periphery of the protective piece 16 is smaller than the outer diameter of the can 6. As a result, a portion of the protective piece 16A does not rest on the outer edge 62 of the can 6, but instead fits into the top surface of the label 1I due to the weight of the label 1I. Therefore, the protective piece 16A can also function as a retaining piece for fixing the label 1 by sandwiching the tab 2 between itself and the first locking piece 11.

[0058] <Dimensions of the cut> Figure 16 illustrates the dimensional relationship between can 6 and label 1I shown in Figure 13. Figure 17 illustrates the dimensional relationship between can 6A and label 1J. Figures 16(a) and 17(a) show cross-sectional views of aluminum can 6 and steel can 6A, respectively. Figures 16(b) and 17(b) show top views showing the dimensions of labels 1I and 1J, respectively.

[0059] As shown in Figure 16(a), the top surface 61 of the can 6 bulges upward in the direction toward the tab 2 from the outer peripheral edge 62 of the top surface 61 of the can 6. The distance d1 between the surface of the top surface 61 of the can 6 near the connection portion 5 on one longitudinal end of the tab 2 and the upper end 65 of the outer peripheral edge 62 of the top surface 61 of the can 6 is, for example, 2 mm.

[0060] As shown in Figure 16(b), when the distance d1 is 2 mm, the distance d2 between the tip of the bulge 7 and the tip of the curved portion 8 on the axis of symmetry of the bulge 7 is, for example, 5 mm. Also, when the distance d1 is 2 mm, the distance d3 between the tips of the curved portions 8 formed at both ends of the cut L1 is 18 mm.

[0061] As shown in Figure 17(a), the top surface 61A of can 6A is recessed from the outer edge 62A of the top surface 61A toward the interior of can 6A. In can 6A, the distance d1 is, for example, 5 mm.

[0062] As shown in Figure 17(b), when the distance d1 is 5 mm, the distance d2 between the tip of the bulge 7J and the tip of the curved portion 8J on the axis of symmetry of the bulge 7J is, for example, 10 mm. Also, when the distance d1 is 5 mm, the distance d3 between the tips of the curved portions 8J formed at both ends of the cut LJ1 is 23 mm.

[0063] The dimensions explained using Figures 16 and 17 are merely examples and should be determined appropriately according to the shape of the can and the size of the label.

[0064] <Summary> A label (1-1J) according to Embodiment 1 of the present invention is a label (1-1J) that is fixed to the upper surface (61, 61A) of a can (6, 6A) provided with tabs (2, 2A), wherein the tabs (2, 2A) have a tension portion (3, 3A) that is pulled when opening the can (6, 6A), a fixing portion (4, 4A) that is fixed to the upper surface (61, 61A) of the can (6, 6A), and a connecting portion (5, 5A) that extends from the tension portion (3, 3A) at a distance from the can (6, 6A) and connects the tension portion (3, 3A) and the fixing portion (4, 4A). Furthermore, with the label (1-1J) fixed to the top surface (61, 61A) of the can (6, 6A), notches (L1-LH1, LJ1) are formed, each having at least a bulge (7-7H, 7J) that bulges out from the outer peripheral edge (62, 62A) of the top surface (61, 61A) toward the tab (2, 2A). The notches (L1-LH1, LJ1) form first locking pieces (11-11H, 11J) that are inserted below the connecting portion (5, 5A) and locked between the tab (2, 2A) and the top surface (61, 61A).

[0065] According to the above configuration, the tab (2, 2A) is inserted below the connecting part (5, 5A) and is locked between the tab (2, 2A) and the top surface (61, 61A) of the can (6, 6A). This allows the label (1-1J) to be securely fixed to the top surface (61, 61A) of the can (6, 6A).

[0066] The label (1-1J) according to embodiment 2 of the present invention is such that, in embodiment 1, the tension portion (3, 3A) is provided with a hook piece (31, 31A) for hooking a finger when opening the can (6, 6A), the tab (2, 2A) has an insertion hole (21, 21A) for inserting a finger, and the first locking piece (11-11H, 11J) is inserted into the connecting portion (5, 5A) from the peripheral edge (52, 52A) of the connecting portion (5, 5A), excluding the hook piece (31, 31A) from the peripheral edge (52, 52A) of the tension portion (3, 3A) that forms the insertion hole (21, 21A).

[0067] According to the above configuration, when inserting the first locking piece (11-11H, 11J) into the connecting part (5, 5A), the possibility of the can (6, 6A) being accidentally opened by the tab (2, 2A) can be reduced.

[0068] In the label (1-1J) according to embodiment 3 of the present invention, the bulging portion (7-7H, 7J) is formed in embodiment 1 or 2 such that it does not follow at least a part of the fixing portion (4, 4A) and does not surround the entire fixing portion (4, 4A).

[0069] According to the above configuration, for example, when force is applied to the shorter side of the tab (2, 2A), the bulging portion (7~7H, 7J) catches on the fixing portion (4, 4A), thus maintaining the label 1H fixed to the top surface (61, 61A) of the can (6, 6A). In addition, a distance is formed between the first locking piece (11~11H, 11J) and the fixing portion (4, 4A) in the portion of the label (1~1J) that surrounds at least a part of the fixing portion (4, 4A), making it easier to remove the label (1~1J) fixed to the top surface (61, 61A) of the can (6, 6A).

[0070] The label (1 to 1J) according to embodiment 4 of the present invention, in any of embodiments 1 to 3, is provided with a second locking piece (12) that locks to the outer edge (62, 62A) (63, 63A) from the opposite direction (D2) to the direction in which the first locking piece (11 to 11H, 11J) is located relative to the connecting portion (5, 5A), when the label (1 to 1J) is fixed to the upper surface (61, 61A) of the can (6, 6A).

[0071] According to the above configuration, the second locking piece (12) is used to lock the outer edge (62, 62A) of the upper surface (61, 61A) of the can (6, 6A) to the outside (63, 63A). This allows the labels (1-1J) to be more securely fixed to the upper surface (61, 61A) of the can (6, 6A).

[0072] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of Symbols]
