[0001] Embodiments of this invention relate to a decorative seal used in a municipal disaster prevention administrative radio system.

Background Art

[0002] In a municipal disaster prevention administrative radio system, for administrative communication with residents in normal times and for disseminating disaster information and administrative communication to residents during disasters, various information is transmitted simultaneously (at the same time) from a master station installed in a municipal government building to slave stations installed outdoors such as schools and evacuation shelters or indoor per-door receivers.

[0003] Here, a slave station installed outdoors may be provided with a sign that can visually identify the affiliation of the slave station. In this case, as the sign, for example, a decorative seal (also referred to as a decorative sheet) printed with a municipal emblem or a municipal name is assumed, and this decorative seal is attached to the surface of the housing that houses the slave station device. In the slave station device, for example, communication processing between the master station and the slave station and various information processing are performed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, an application sheet is attached to cover the surface of the decorative seal, and this application sheet is preferably peeled off after all the work (for example, the installation work of the slave station) at the site is completed in order to protect the decorative seal from scratches and dirt.

[0006] However, in conventional decorative stickers, the application sheet is laminated onto the surface of a transparent resin layer (i.e., an overcoat printing layer) that is applied to cover the printed surface on which the above-mentioned markings are printed, and the overcoat printing layer and the application sheet are firmly bonded (adhered) to each other.

[0007] Therefore, depending on the degree of bonding strength (adhesion) between the application sheet and the overcoat printing layer, this bonding strength (adhesion) may exceed the adhesive strength between the decorative sticker and the surface of the housing. As a result, when the application sheet is peeled off, the entire decorative sticker may peel off from the surface of the housing along with the application sheet.

[0008] Furthermore, since the application sheet and the overcoat printing layer cannot be given high rigidity on their own, decorative seals in which the application sheet is laminated on the surface of the overcoat printing layer have difficulty maintaining a consistent overall contour shape. For example, the decorative seals are prone to deformation, twisting, and bending.

[0009] Therefore, when applying decorative stickers to the surface of the casing before shipment, it becomes difficult to accurately position the decorative stickers relative to the pre-set application locations. As a result, the application of decorative stickers becomes time-consuming and laborious, and there is a risk that, for example, wrinkles may form in the decorative stickers after application, or air bubbles may form between the decorative stickers and the surface of the casing.

[0010] The objective of the present invention is to provide a decorative seal that allows for easy peeling of only the application sheet, while maintaining a consistent overall contour shape, thereby enabling quick, easy, and accurate positioning at a predetermined application location. [Means for solving the problem]

[0011] According to the embodiment, a decorative sticker for use in a municipal disaster prevention administrative radio system that simultaneously transmits various information from a master station to slave stations comprises a base material having a surface on which various signs can be printed and a back surface that can be attached to a slave station, a backing paper that is peelably attached to the back surface, a laminate film that is irremovably attached to the surface, and an application sheet that is peelably attached to the laminate film, the application sheet being peelably attached to the surface of the laminate film, and the surface of the laminate film being a smooth surface without irregularities. The decorative sticker has a four-layer structure in which a backing sheet, base material, laminate film, and application sheet are laminated in that order. . [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0013] "One Embodiment" FIG. 1 is a conceptual diagram of the municipal disaster prevention administrative radio system 1. This system 1 is established for notifying residents of disaster information during disasters and for administrative communication as part of services to residents during normal times, and is configured to be able to transmit various types of information simultaneously, for example, by voice, text, or image. In FIG. 1, as an example, a system 1 for transmitting various types of information to residents by voice is assumed, and the system 1 includes a master station 2, slave stations 3 (repeater slave stations 3a), household receivers 4, and relay stations 5.

[0014] As shown in FIG. 1, the master station 2 is installed inside the municipal hall 6 and is configured to be able to transmit various types of information such as disaster information. The master station 2 is configured to be able to communicate with the fire department 7 that has jurisdiction over the municipal area, and it is also possible to remotely control the information transmission from the master station 2 from the fire department 7.

[0015] The slave station 3 is equipped with a speaker 8 and is installed outdoors (such as in schools and shelters), and is configured to be able to broadcast the information transmitted from the master station 2 to residents through the speaker 8. The household receiver 4 is installed for each house in the municipal area and is configured to be able to convert the information transmitted from the master station 2 into voice and transmit it to residents.

[0016] The relay station 5 and the repeater slave station 3a are installed in a wide-area municipality that has an area where the radio waves (synchronization waves) from the master station 2 do not reach. The relay station 5 is configured to be able to expand the range where radio waves (synchronization waves) reach. The repeater slave station 3a is configured to be able to retransmit the radio waves (synchronization waves) from the master station 2 transmitted via the relay station 5 to the slave stations 3 and household receivers 4 installed in areas where the radio waves (synchronization waves) do not reach.

[0017] According to this system 1, information transmitted from a master station 2 located inside the municipal office building 6 is converted into voice via substations 3 located outdoors in places like schools and evacuation centers, and individual receivers 4 located inside houses, and transmitted simultaneously to all residents of the municipality. In areas where the radio waves (broadcast waves) from the master station 2 do not reach, the information is routed through relay stations 5 and retransmitting substations 3a to ensure that all residents of the municipality are not missed.

[0018] In the municipal disaster prevention administrative radio system 1 described above, each substation 3 (hereinafter, including the retransmitting substation 3a) is equipped with a mark that allows for visual identification of its affiliation. As an example, Figure 1 shows the application of decorative stickers 9 (also called decorative sheets) on which various marks can be printed. The decorative stickers 9 are configured to be affixed to the substation 3 (specifically, the surface of the housing 12 (opening / closing door 12a) described later).

[0019] Substation 3 is constructed by mounting a speaker 8, an antenna 11, and substation equipment (not shown) on a support pole 10 erected in the area for the aforementioned public address broadcast. The substation equipment consists of, for example, devices for communication processing between the master station 2 and substation 3 and various information processing, and is housed in a casing 12 equipped with an opening and closing door 12a.

[0020] The housing 12, which contains the substation equipment, is fixed to the support column 10. The housing 12 is fixed by, for example, fastening it to the support column 10 while a worker is on a ladder or step stool. The decorative seal 9 described above is affixed to the surface of the housing 12, which is positioned at a relatively high location. In Figure 1, as an example, the decorative seal 9 is affixed to a predetermined area on the surface of the opening / closing door 12a of the housing 12. A predetermined area could be, for example, a part of the housing from which the decorative seal 9 can be seen from the outside (even from a relatively long distance).

[0021] Figure 2 is an external configuration diagram of the decorative sticker 9. As shown in Figure 2, the decorative sticker 9 has a four-layer structure in which a backing paper 13, a base material 14, a laminate film 15, and an application sheet 16 are laminated in this order. As for the contour shape of the decorative sticker 9, various contour shapes such as rectangular, circular, elliptical, and triangular shapes can be applied in plan view. In Figure 2, as an example, a decorative sticker 9 with a rectangular contour is assumed, and this decorative sticker 9 has a mark 17 printed on it, for example, consisting of a municipal emblem 17a and a municipal name 17b, as the destination of the substation 3 described above.

[0022] Figure 3 is an exploded perspective view of the decorative sticker 9. The backing paper 13, base material 14, laminate film 15, and application sheet 16 that make up the decorative sticker 9 have rectangular contours of the same size in a plan view. In Figure 3, as an example, the thicknesses of the four components of the decorative sticker 9 (i.e., the backing paper 13, base material 14, laminate film 15, and application sheet 16) are set to be the same, but it goes without saying that the thicknesses of each component 13, 14, 15, and 16 can be set according to the material and application, for example.

[0023] As shown in Figure 3, the base material 14 has a surface 14a on which the above-mentioned mark 17 (municipal emblem 17a, municipal name 17b) can be printed. The municipal emblem 17a and the municipal name 17b are printed on the surface 14a of the base material 14, side by side. However, this is just one example, and variations such as printing only the municipal emblem or only the municipal name are also conceivable. Furthermore, the base material 14 has a back surface 14b provided parallel to the opposite side of the surface surface 14a. An adhesive (not shown) is applied to the back surface 14b of the base material 14, and this adhesive makes it possible to bond the base material 14 (back surface 14b) to the substation 3 (the surface of the housing 12 (opening / closing door 12a) described above).

[0024] Furthermore, the substation 3 to which the decorative sticker 9 is attached is installed outdoors in an environment where it is exposed to wind and rain and direct sunlight. For this reason, it is preferable to use a material with excellent water resistance and heat resistance (for example, polyvinyl chloride) for the base material 14. In addition, it is preferable to use an adhesive with excellent water resistance and heat resistance as the bonding agent for joining the base material 14 to the substation 3.

[0025] The backing paper 13 is provided so as to completely cover the entire back surface 14b of the base material 14 without any gaps, and is peelably attached to the back surface 14b of the base material 14. As the backing paper 13, a resin-processed release paper (double-sided polyethylene coated, one-sided silicone treated paper) can be used. The backing paper 13 is applied to temporarily protect the adhesive applied to the back surface 14b of the base material 14 and is not reused, so it is preferable to make it from a low-cost material.

[0026] The laminate film 15 is provided so as to completely cover the entire surface 14a of the substrate 14 without any gaps, and is irremovably bonded to the surface 14a of the substrate 14. The method for bonding the laminate film 15 to the surface 14a of the substrate 14 can be an existing adhesive method using a transparent adhesive.

[0027] The laminate film 15 is a highly transparent adhesive film made of, for example, polyester, polypropylene, or polyvinyl chloride. When the laminate film 15 is bonded to the surface 14a of the base material 14, the mark 17 printed on the surface 14a of the base material 14 remains visible through the laminate film 15. Furthermore, by using the same polyvinyl chloride material for the laminate film 15 as the base material 14, weather resistance can be improved. Additionally, it is anticipated that the decorative seal 9 may expand or contract due to temperature changes after being attached to the substation 3 (the surface of the housing 12 (opening / closing door 12a)). In this case, if the base material 14 and the laminate film 15 are made of the same material, they will expand or contract by the same amount, thereby preventing problems such as cracking and peeling. In particular, polyvinyl chloride is a material that expands and contracts easily, making it resistant to temperature changes.

[0028] Furthermore, the laminate film 15 has higher rigidity than the conventional overcoat printing layer described above. As a result, the decorative seal 9, which includes the laminate film 15, has the rigidity to maintain a consistent overall contour shape.

[0029] In addition, the laminate film 15 reinforces the base material 14 and also functions as a reinforcing and protective material that protects the markings 17 printed on the surface 14a of the base material 14. This improves the durability and tear strength of the base material 14 itself, and the laminate film 15 blocks oxygen (ozone), water, heat, and light, preventing the markings 17 on the surface 14a of the base material 14 from becoming dirty or deteriorating prematurely.

[0030] Furthermore, the glossiness of the laminate film 15 itself enhances the decorative effect of the surface 14a of the substrate 14 covered with the laminate film 15, thereby giving the sign 17 printed on the surface 14a an additional sense of luxury.

[0031] In this type of laminate film 15, the back surface 15b is irremovably bonded to the surface 14a of the substrate 14, and the surface 15a (opposite the back surface 15b) is a smooth surface without irregularities. The application sheet 16, described later, is provided so as to cover the entire laminate film 15 and is peelably attached to the surface 15a of the laminate film 15.

[0032] Figure 3 shows an example where the adhesive portion for peelably attaching the application sheet 16 to the surface 15a of the laminate film 15 is configured to extend across the entire contact area of ​​the application sheet 16 that contacts the surface 15a of the laminate film 15. In this case, the entire contact area is configured as an adhesive area where the application sheet 16 and the surface 15a of the laminate film 15 are peelably attached to each other. In short, the entire surface of the application sheet 16 (excluding the peeling force application portion 18 described later) is peelably attached to the surface 15a of the laminate film 15 by an adhesive (not shown).

[0033] The application sheet 16 is a weakly adhesive sheet made of, for example, polypropylene or polyethylene terephthalate (PET). This allows the application sheet 16 to be peelably attached to the laminate film 15 and to be removed cleanly without leaving any adhesive residue when re-peeled.

[0034] Furthermore, the decorative sticker 9 described above has a peeling force application portion 18 (also called a peeling allowance) that can apply a peeling force to the application sheet 16 when the application sheet 16 is peeled off. The peeling force application portion 18 is provided on a part of the application sheet 16 and is configured not to be attached to the surface 15a of the laminate film 15.

[0035] The peeling force application area 18 is located on the edge of the application sheet 16. As an example in Figure 3, the peeling force application area 18 is located on one of the four corners 16t (also called corners) of the rectangular edge of the application sheet 16. The peeling force application area 18 has a triangular contour in plan view. As a result, a triangular non-adhered area that is not attached to the surface 15a of the laminate film 15 is configured as the peeling force application area 18. Note that the non-adhered area can be created, for example, by attaching a triangular piece of paper to the edge of the application sheet 16, thereby creating an area that is not attached to the surface 15a of the laminate film 15.

[0036] In this case, the boundary 18s between the non-adhered area and the other area (i.e., the adhered area where the application sheet 16 and the surface 15a of the laminate film 15 are peelably adhered to each other) is configured in a straight line. This straight boundary 18s extends straight along a direction that diagonally crosses two sides 16p of adjacent application sheets 16 that constitute the corner 16t (i.e., two mutually orthogonal sides 16p).

[0037] Here, we consider the state before the back surface 14b of the base material 14 is joined to the substation 3 (the housing 12 (opening / closing door 12a) described above). At this time, the backing paper 13 is peelably attached to the back surface 14b of the base material 14. The back surface 15b of the laminate film 15 is irremovably joined to the front surface 14a of the base material 14. The application sheet 16 is peelably attached to the front surface 15a of the laminate film 15.

[0038] In this state, the adhesion force between the backing sheet 13 and the back surface 14b of the base material 14 is set to be smaller than the bonding force between the back surface 15b of the laminate film 15 and the front surface 14a of the base material 14, and the adhesion force between the front surface 15a of the laminate film 15 and the application sheet 16. That is, if the adhesion force between the backing sheet 13 and the back surface 14b of the base material 14 is F1, the bonding force between the back surface 15b of the laminate film 15 and the front surface 14a of the base material 14 is F2, and the adhesion force between the front surface 15a of the laminate film 15 and the application sheet 16 is F3, then the relationship F1 < F3 < F2 is satisfied.

[0039] On the other hand, assume the state after joining the back surface 14b of the base material 14 to the slave station 3 (housing 12 (opening / closing door 12a)). At this time, the back surface 14b of the base material 14 from which the backing sheet 13 has been peeled is joined to the surface of the slave station 3 (housing 12 (opening / closing door 12a)). The back surface 15b of the laminate film 15 is inseparably joined to the front surface 14a of the base material 14. The application sheet 16 is detachably attached to the front surface 15a of the laminate film 15.

[0040] In this state, the adhesion force between the application sheet 16 and the front surface 15a of the laminate film 15 is set to be smaller than the bonding force between the back surface 14b of the base material 14 and the slave station 3 in the state of being joined to the slave station 3. That is, if the adhesion force between the application sheet 16 and the front surface 15a of the laminate film 15 is the above-mentioned F3, and the bonding force between the back surface 14b of the base material 14 and the slave station 3 in the state of being joined to the slave station 3 is F4, then the relationship F3 < F4 is satisfied.

[0041] Regarding the four forces F1, F2, F3, and F4 described above, the relationship between the bonding force F2 between the back surface 15b of the laminate film 15 and the front surface 14a of the base material 14 and the bonding force F4 between the back surface 14b of the base material 14 and the sub-station 3 when bonded to the sub-station 3 is as follows: If the state in which the base material 14 (back surface 14b) is bonded to the sub-station 3 (the front surface of the housing 12 (opening / closing door 12a)) (in other words, the state in which the decorative seal 9 does not easily fall off the sub-station 3) can be maintained for a long period of time, then F2<F4、F2=F4、F2> Any of the F4 relationships may be satisfied.

[0042] Figure 4 is a diagram showing the arrangement of a decorative seal 9 in which the back surface 14b of the base material 14 is joined to the substation 3 (housing 12 (opening / closing door 12a)). As shown in Figure 4, the decorative seal 9, which has a four-layer structure (backing paper 13, base material 14, laminate film 15, application sheet 16), is peeled off only from the back surface 14b of the base material 14 before shipment (for example, at the factory). Then, while maintaining the remaining three-layer structure (base material 14, laminate film 15, application sheet 16), the back surface 14b of the base material 14 is joined to the substation 3 (the surface of the housing 12 (opening / closing door 12a)).

[0043] At this time, the decorative seal 9, which includes the laminate film 15, exhibits rigidity that allows it to maintain a constant overall contour shape. This makes it possible to position and bond the decorative seal 9 (the back surface 14b of the base material 14) to a predetermined attachment position on the surface of the housing 12 (opening / closing door 12a) without deformation, twisting, or bending.

[0044] Subsequently, the decorative seal 9, consisting of a three-layer structure (base material 14, laminate film 15, and application sheet 16), is attached to the surface of the housing 12 (opening / closing door 12a) and shipped together with the housing 12 to the site (for example, the installation location of the substation 3). The application sheet 16 is peeled off after all work (for example, the installation of the substation 3) is completed at the site.

[0045] Here, for example, the peeling force application part 18 is grasped with the fingers and pulled. The pulling motion is transmitted from the peeling force application part 18 to the application sheet 16, thereby applying a peeling force to the application sheet 16. Since the surface 15a of the laminate film 15 is made up of a smooth surface without irregularities, the application sheet 16 can be smoothly peeled off the surface 15a of the laminate film 15.

[0046] At this time, the peeling force may be varied. For example, by applying a large peeling force, the application sheet 16 can be peeled off quickly in a short amount of time. Conversely, by applying a small peeling force, the application sheet 16 can be peeled off carefully over a longer period of time.

[0047] Figure 5 is a diagram showing the arrangement of the decorative sticker 9 after the application sheet 16 has been peeled off. As shown in Figure 5, with the application sheet 16 peeled off, the decorative sticker 9 has the back surface 14b of the base material 14 joined to the substation 3 (the surface of the housing 12 (opening / closing door 12a)), and the entire surface 14a of the base material 14 (i.e., the printed surface on which the sign 17 (municipal emblem 17a, municipal name 17b) is printed) is covered without any gaps by the laminate film 15.

[0048] In this state, the laminate film 15 functions as a reinforcing and protective material. As a result, the base material 14 itself is reinforced over a long period of time, and the surface 14a (printed surface) of the base material 14 is protected.

[0049] As described above, in this embodiment, the decorative sticker 9 consists of a four-layer structure (backing paper 13, base material 14, laminate film 15, and application sheet 16). The application sheet 16 is peelably attached to the surface 15a of the laminate film 15, and the surface 15a of the laminate film 15 is a smooth surface without irregularities. As a result, the application sheet 16 is easily peeled off the surface 15a of the laminate film 15. Consequently, the application sheet 16 can be cleanly peeled off the surface 15a of the laminate film 15 without leaving any adhesive residue.

[0050] According to this embodiment, the adhesive force between the application sheet 16 and the surface 15 of the laminate film 15 is set to be smaller than the adhesive force between the back surface 14b of the base material 14 and the substation 3 when it is bonded to the substation 3 (the surface of the housing 12 (opening / closing door 12a)). As a result, when the application sheet 16 is peeled off again after all work (for example, the installation of the substation 3) is completed on site, the entire decorative seal 9 will not peel off from the substation 3 (the surface of the housing 12 (opening / closing door 12a)) together with the application sheet 16. As a result, only the application sheet 16 can be peeled off smoothly.

[0051] According to this embodiment, the application sheet 16 has a peeling force application part 18 that can apply a peeling force to the application sheet 16 when peeling it off. This makes it easier to peel off the application sheet 16. For example, by pinching the peeling force application part 18 with your fingers and pulling, the application sheet 16 can be smoothly peeled off from the surface 15a of the laminate film 15. As a result, by applying a large peeling force, the application sheet 16 can be peeled off quickly in a short amount of time, and by applying a small peeling force, the application sheet 16 can be peeled off carefully over time.

[0052] According to this embodiment, in the decorative seal 9 consisting of a four-layer structure (backing paper 13, base material 14, laminate film 15, and application sheet 16), the laminate film 15 has rigidity that allows the overall contour shape of the decorative seal 9 to be maintained at a constant level. As a result, the decorative seal 9, including the laminate film 15, maintains a constant overall contour shape. In this state, the decorative seal 9 (back surface 14b of the base material 14) can be accurately positioned and bonded to the pre-set bonding position on the surface of the housing 12 (opening / closing door 12a) in a short time without deforming, twisting, or bending, for example. As a result, the efficiency of the decorative seal 9 bonding work can be significantly improved compared to conventional methods. Furthermore, when the decorative seal 9 is bonded, there is no wrinkle on the decorative seal 9, nor is there any air bubble formation between the decorative seal 9 and the surface of the housing 12 (opening / closing door 12a).

[0053] According to this embodiment, in a decorative seal 9 consisting of a four-layer structure (backing paper 13, base material 14, laminate film 15, and application sheet 16), the laminate film 15 functions as a reinforcing and protective member that reinforces the base material 14 and protects the mark 17 printed on the surface 14a of the base material 14. This improves the durability and tear strength of the base material 14 itself, and the laminate film 15 blocks oxygen (ozone), water, heat, and light, preventing the mark 17 on the surface 14a of the base material 14 from becoming dirty or deteriorating prematurely. In addition, the glossiness of the laminate film 15 itself enhances the decorative effect of the surface 14a of the base material 14 covered with the laminate film 15, thereby giving the mark 17 printed on the surface 14a of the base material 14 an additional sense of luxury.

[0054] According to this embodiment, in a decorative seal 9 consisting of a four-layer structure (backing paper 13, base material 14, laminate film 15, and application sheet 16), the adhesive force between the backing paper 13 and the back surface 14b of the base material 14 is set to be smaller than the adhesive force between the back surface 15b of the laminate film 15 and the front surface 14a of the base material 14, and also smaller than the adhesive force between the front surface 15a of the laminate film 15 and the application sheet 16. As a result, the backing paper 13 is easily peeled off from the back surface 14b of the base material 14. Consequently, the backing paper 3 can be easily peeled off in a short time before shipment (for example, at the factory).

[0055] "First Variation" Figure 6 is a diagram showing the arrangement of the peeling force application part 18 according to the first modified example. In this modified example, the peeling force application part 18 is located on the edge of the application sheet 16. In Figure 6, as an example, the peeling force application part 18 is located at one of the four corners 16t (also called corners) of the edge of the rectangular application sheet 16.

[0056] As shown in Figure 6, the peeling force application area 18 of this modified example is configured as a triangular non-adhered area in plan view, similar to the embodiment described above. However, the difference is that the boundary 18s between this non-adhered area and the other area (i.e., the adhesive area where the application sheet 16 and the surface 15a of the laminate film 15 are peelably adhered to each other) is configured in an arc shape.

[0057] The arc-shaped boundary 18s extends in an arc shape, bulging towards the intersection point 16x of two sides 16p (i.e., two mutually orthogonal sides 16p) of adjacent application sheets 16 that constitute the corner 16t. The other configurations are the same as those of the decorative seal in the embodiment described above, so their description is omitted.

[0058] As described above, according to the first modification, by configuring the boundary 18s of the peeling force application part 18 in an arc shape, the peeling force acting on the application sheet 16 can be distributed when the peeling force application part 18 is grasped and pulled with the fingers.

[0059] As a result, even if the peeling force application part 18 is rapidly pulled and a large peeling force is applied to the application sheet 16 in a short time, stress will not concentrate on the application sheet 16. As a result, the application sheet 16 can be peeled off smoothly in a short time without damaging it. The other effects are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0060] "Second variation" Figure 7 is a diagram showing the arrangement of the peeling force application parts according to the second modified example. In this modified example, the peeling force application parts 18 are located on the edge of the application sheet 16. As an example, in Figure 7, the peeling force application parts 18 are provided at each of the four corners 16t (also called corners) of the edge of the rectangular application sheet 16.

[0061] As shown in Figure 7, the peeling force application portion 18 of this modified example is configured as a triangular non-adhered area in plan view, similar to the embodiment described above. The boundary 18s between this non-adhered area and the other area (i.e., the adhesive area where the application sheet and the surface of the laminate film are peelably adhered to each other) is configured as a straight line. The other configurations are the same as those of the decorative seal in the embodiment described above, so their description is omitted.

[0062] As described above, according to the second modification, by providing the peeling force application parts 18 at the four corners 16t of the application sheet 16, peeling forces can be applied to the application sheet 16 from four directions when peeling off the application sheet 16.

[0063] By the way, as mentioned above, the housing 12 to which the decorative sticker 9 is attached (i.e., the housing 12 housing the substation equipment) is located at a relatively high position among the substations 3. For this reason, when the application sheet 16 is peeled off again after all the work (for example, the installation of substations 3) is completed on site, the workers are forced to peel off the application sheet 16 in an unstable position, such as while standing on a ladder or stepladder.

[0064] However, as shown in this modified example, by providing the peeling force application parts 18 at the four corners 16t of the application sheet 16, the number of options for peeling force application parts 18 that can be grasped by the fingers can be increased.

[0065] This allows the worker to select the peeling force application part 18 that is easiest to grip, even when in an unstable position such as climbing a ladder or stepladder. As a result, the application sheet 16 can be peeled off quickly, easily, and reliably while ensuring the worker's safety. The other effects are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0066] "Third Variation" Figure 8 is a diagram showing the arrangement of the peeling force application part 18 according to the third modified example. In this modified example, the peeling force application part 18 is configured to protrude from the application sheet 16. In Figure 8, as an example, the peeling force application part 18 is provided at one of the four corners 16t (also called corners) of the edge of the rectangular application sheet 16, and is configured to protrude from there along the same plane as the application sheet 16.

[0067] As shown in Figure 8, the peeling force application portion 18 of this modified example has an arc-shaped contour in plan view. In this case, the arc-shaped peeling force application portion 18 protrudes outside the edge of the application sheet 16. As a result, the arc-shaped non-adhered area that is not attached to the surface 15a of the laminate film 15 is configured as the peeling force application portion 18. In this case, in addition to the arc shape, various contour shapes such as rectangular or triangular shapes can be applied to the peeling force application portion 18. Note that the other configurations are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0068] As described above, according to the third modification, by configuring the peeling force application part 18 to protrude from the edge of one corner 16t of the application sheet 16, it becomes easier to grasp the peeling force application part 18 with your fingers when peeling off the application sheet 16. The other effects are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0069] "Fourth variation" Figure 9 is a diagram showing the arrangement of the peeling force application part 18 according to the fourth modified example. In this modified example, the peeling force application part 18 is configured to protrude from the application sheet 16. In Figure 9, as an example, the peeling force application part 18 is provided at two of the four corners 16t (also called corners) of the edge of the rectangular application sheet 16, and is configured to protrude from there along the same plane as the application sheet 16.

[0070] As shown in Figure 9, the peeling force application parts 18 of this modified example each have an arc-shaped contour that protrudes from the edges of two sides 16p of the application sheet 16, which are in a positional relationship parallel to each other. In this case, the configuration of each peeling force application part 18 is the same as that of the third modified example described above, and the other configurations are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0071] As described above, according to the fourth modification, by configuring the peeling force application portion 18 to protrude from the edges of the two corners 16t of the application sheet, the number of options for the peeling force application portion 18 that can be grasped by the fingers can be increased.

[0072] This allows the worker to select the peeling force application part 18 that is easiest to grip, even when in an unstable position such as climbing a ladder or step stool. As a result, the application sheet 16 can be peeled off quickly, easily, and reliably while ensuring the worker's safety. The other effects are the same as those of the decorative seal in the third modified example and embodiment described above, so their explanation will be omitted.

[0073] "Fifth Variation" Figure 10 is a diagram showing the arrangement of the peeling force application part 18 according to the fifth modified example. In this modified example, the peeling force application part 18 is located on the edge of the application sheet 16. In Figure 10, as an example, the peeling force application part 18 is provided along one of the four edges (16p) of the rectangular application sheet 16.

[0074] As shown in Figure 10, the peeling force application area 18 in this modified example is configured as a rectangular non-adhesive area that extends in a long, narrow shape along one side 16p of the application sheet 16. The other configurations are the same as those of the decorative seal 9 in the embodiment described above, so their description will be omitted.

[0075] As described above, according to the fifth modification, by extending the peeling force application part 18 broadly along one side 16p of the application sheet 16, it becomes easier to grasp the peeling force application part 18 with the fingers, and when pulling while grasping the peeling force application part 18 with the fingers, the peeling force acting on the application sheet 16 can be distributed.

[0076] As a result, even if the peeling force application part 18 is rapidly pulled and a large peeling force is applied to the application sheet 16 in a short time, stress will not concentrate on the application sheet 16. As a result, the application sheet 16 can be peeled off smoothly in a short time without damaging it. The other effects are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0077] "Sixth Variant" Figure 11 is a diagram showing the arrangement of the peeling force application part 18 according to the sixth modified example. In this modified example, the peeling force application part 18 is located on the edge of the application sheet 16. As an example, in Figure 11, the peeling force application part 18 is provided along the entire edge (4 sides 16p) of the rectangular application sheet 16.

[0078] As shown in Figure 11, the peeling force application area 18 in this modified example is configured as a non-adhesive area that extends continuously along the edge of the application sheet 16. In other words, the peeling force application area 18 is configured as a long, narrow, continuous, hollow rectangular non-adhesive area along the entire circumference of all four sides 16p of the application sheet 16. The other configurations are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0079] As described above, according to the sixth modification, by extending the peeling force application portion 18 over a wide area (i.e., a 360-degree range) along all four sides 16p of the application sheet 16, it is possible to realize a peeling force application portion 18 that can be grasped by fingers from any direction.

[0080] This allows peeling force to be applied from all sides of the application sheet 16 when it is peeled off. Note that other effects are the same as those of the decorative seal in the fifth modified example and embodiment described above, so their explanation will be omitted.

[0081] "Seventh variation" Figure 12 is a diagram showing the arrangement of the peeling force application part 18 according to the seventh modified example. In this modified example, the peeling force application part 18 is configured to protrude from the application sheet 16. In Figure 12, as an example, the peeling force application part 18 is provided so as to divide the rectangular application sheet 16 in the center.

[0082] As shown in Figure 12, the peeling force application portion 18 of this modified example is provided in a portion 16g obtained by cutting the application sheet 16 in half in a plan view. This cut portion 16g is composed of two straight cutting edges 16a and 16b that are adjacent to each other and run parallel to one another. The peeling force application portion 18 is configured to protrude rectangularly from the application sheet 16, while being continuous with these two cutting edges 16a and 16b. The other configurations are the same as those of the decorative seal in the embodiment described above, so their description will be omitted.

[0083] As described above, according to the seventh modification, peeling force application parts 18 are provided that are continuous with and protrude from the two cutting edges 16a and 16b that divide the center of the application sheet 16. This makes it easier to grasp the peeling force application parts 18 with your fingers, and allows the application sheet 16 to be peeled off from both sides of the cutting portion 16g that divides it into two equal parts.

[0084] As a result, the peeling force applied to each separated application sheet 16 from the peeling force application part 18 is halved (reduced), and as a result, each application sheet 16 can be peeled off smoothly in a short time with light peeling force. The other effects are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0085] "Variation 8" Figure 13 is a diagram showing the arrangement of the adhesive portion according to the eighth modified example. In the embodiment described above, it was assumed that the entire surface of the application sheet 16 (i.e., the entire contact area described above) was an adhesive area that was peelably attached to the surface 15a of the laminate film 15. However, in this modified example, the adhesive portion is configured to include an adhesive area in at least one location within its entire contact area.

[0086] As an example, Figure 13 shows that the adhesive portion of this modified example is composed of an adhesive area R1 and a non-adhesive area R2 in which the application sheet 16 and the surface 15a of the laminate film 15 are not adhered to each other, which are alternately repeated at equal intervals along the direction traversing the application sheet 16.

[0087] As shown in Figure 13, in the adhesive portion of this modified example, rectangular adhesive areas R1 and non-adhesive areas R2, which are of the same size, extend between two parallel sides 16p of the application sheet 16, and are arranged alternately at equal intervals along these two sides 16p. The other configurations are the same as those of the decorative seal in the embodiment described above, so their description is omitted.

[0088] As described above, according to the eighth modification, by arranging the adhesive area R1 and the non-adhesive area R2 alternately at equal intervals, the adhesive area or adhesive force of the application sheet 16 attached to the surface 15a of the laminate film 15 can be reduced compared to the case where the entire surface of the application sheet 16 (i.e., the entire contact area) is used as the adhesive area, as in the above embodiment. As a result, the peeling force applied to the application sheet 16 from the peeling force application part 18 is reduced, and as a result, the application sheet 16 can be peeled off smoothly in a short time with light peeling force. The other effects are the same as those of the decorative seal in the above embodiment, so their explanation will be omitted.

[0089] "The 9th Variation" Figure 14 is a diagram showing the arrangement of the adhesive portion according to the ninth modified example. The adhesive portion of this modified example is an improvement over the eighth modified example described above. As an example, in Figure 14, multiple adhesive areas R1 having a circular outline in plan view are provided, and these circular adhesive areas R1 are arranged at equal intervals along the direction traversing the application sheet 16.

[0090] As shown in Figure 14, in the adhesive portion of this modified example, circular adhesive areas R1 of the same size are scattered at equal intervals across the entire surface of the application sheet 16 (i.e., the entire contact area described above).

[0091] In this configuration, the circular adhesive area R1 and the other areas (i.e., the non-adhesive area R2) are arranged alternately at equal intervals along the direction traversing the application sheet 16. The other configurations are the same as those of the decorative seal in the embodiment described above, so their explanation will be omitted.

[0092] As described above, according to the ninth modification, the application sheet 16 can be peeled off smoothly in a short time with light peeling force, similar to the eighth modification described above. Other effects are the same as those of the eighth modification and the decorative seal of the embodiment described above, so their explanation is omitted.

[0093] "The 10th Variation" In the embodiments and modifications described above, the size of the peeling force application portion 18 was not specifically mentioned. However, the size of the peeling force application portion 18 is set according to the size of the application sheet 16, and is therefore not particularly limited here.

[0094] In the eighth and ninth modifications described above, a bonding section was assumed in which bonding areas R1 and non-bonding areas R2 were arranged alternately at equal intervals. However, bonding areas R1 and non-bonding areas R2 may be arranged alternately in a random manner. In this case, bonding areas R1 and non-bonding areas R2 may be configured with contour shapes of different sizes.

[0095] Although one embodiment of the present invention and several variations have been described above, these embodiments and variations are presented as examples and are not intended to limit the scope of the invention. These embodiments and variations can be implemented in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of symbols]
