Description

[Technical field]

[0001] The present invention relates to a protective seal for protecting an object to be protected. [Background technology]

[0002] Conventionally, protective stickers are known that protect photos, drawings, etc. when a user sticks them in a desired location or sticks them on belongings to carry them around (for example, Patent Document 1). The photo protection and decoration sticker described in Patent Document 1 is composed of a transparent first film and a transparent second film. The first film has a decorative print layer on the periphery of one side, and a transparent adhesive layer on the other side. The second film is attached to the adhesive layer of the first film. In addition, the second film is divided into a periphery and a protective portion by an annular cut.

[0003] When the peripheral portion of the second film is peeled off from the first film, the photo protection and decoration sticker generates adhesive force at the peripheral portion surrounding the protective portion. With the photo positioned on the non-adhesive protective portion, the photo protection and decoration sticker can hold the photo located on the protective portion on the surface of the item by attaching the adhesive peripheral portion to any item. Also, the photo protection and decoration sticker can protect the photo by covering it with the protective portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Registered Utility Model Publication No. 3130284 Summary of the Invention [Problem to be solved by the invention]

[0005] The photo protection and decoration sticker described in Patent Document 1 protects a photo on an article by attaching the adhesive surface of the protective part, which has adhesive strength all around, to the surface of the article while the protective part is overlapped on the photo placed on the surface of the article. In this case, the photo protection and decoration sticker must be positioned relative to the photo that is not fixed on the article, and the adhesive surface must be attached to the article without moving the photo, making positioning relative to the photo and the article cumbersome.

[0006] An object of the present invention is to provide a protective sticker that can be easily positioned relative to an object to be protected and relative to an item to which it is attached. [Means for solving the problem]

[0007] The present inventors have studied the configuration of a protective sticker that can be easily positioned relative to an object to be protected and an object to which the sticker is to be affixed. As a result of extensive studies, the present inventors have come up with the following configuration.

[0008] A protective seal according to an embodiment of the present invention is a protective seal for attaching an object to be protected to an object to be affixed and protecting the object, and includes a base material and a plurality of adhesive portions formed on one surface of the base material. The protective seal is affixed to a portion of the object to be protected and a portion of the object to be affixed by the plurality of adhesive portions.

[0009] In the above-mentioned configuration, the protective seal is attached to a part of the protection object and a part of the attachment object by a part of the adhesive portion. Thus, the protective seal maintains the position of the protection object relative to the base material and the position of the attachment object relative to the base material by the adhesive portions. Furthermore, the protective seal protects the protection object. In addition, the protective seal may be attached to an arbitrary position of the attachment object together with the protection object by the adhesive portions, with the protection object attached to a part of the adhesive portions. That is, the protective seal is attached to the protection object by the adhesive portions, with the base material and the protection object being integrated together. In this way, the protective seal can be positioned relative to the protection object by attaching a part of the adhesive portion to the protection object, and then positioned relative to the attachment object by attaching a part of the adhesive portion to the attachment object. This makes it easy to position the protective seal relative to the protection object and the attachment object.

[0010] From another viewpoint, the protective sticker of the present invention preferably includes the following configuration: The plurality of adhesive portions are composed of two adhesive portions, a first adhesive portion and a second adhesive portion. The base material is attached to one end of the protection object positioned in the area where the protection object is protected and a part of the object to be affixed by the first adhesive portion, and is attached to the other end of the protection object positioned in the area where the protection object is protected and a part of the object to be affixed by the second adhesive portion, covering the protection object in a state where a part other than the part where the first adhesive portion and the second adhesive portion are positioned is not affixed to the protection object and the object to be affixed.

[0011] In the above-mentioned configuration, the protective seal is attached to the object to be protected by a portion of the first adhesive portion and a portion of the second adhesive portion of the base material, the portion being located in the area where the object to be protected is protected. At this time, the base material is positioned relative to both ends of the object to be protected. The protective seal attached to the object to be protected by a portion of the first adhesive portion and a portion of the second adhesive portion is attached to an arbitrary position of the object to be affixed by a portion of the first adhesive portion to which the object to be protected is not affixed and a portion of the second adhesive portion to which the object to be protected is not affixed. In addition, the protective seal is not attached to the object to be affixed and the object to be protected by a portion of the base material other than the portion where the first adhesive portion and the second adhesive portion are located, so that the protective film does not twist, wrinkle, or have air pockets. This makes it easy to position the protective seal relative to the object to be protected and the object to be affixed.

[0012] From another viewpoint, the protective sticker of the present invention preferably includes the following configuration. The protective sticker has a release paper that protects the multiple adhesive portions. The release paper has a release agent applied to one side, and at least covers the multiple adhesive portions in a state where the multiple adhesive portions are affixed to the one side to which the release agent is applied, and has a mark on the other side for positioning the object to be protected in an area where the object to be protected is protected. The release paper is divided into a portion where some of the multiple adhesive portions are affixed and a portion where other adhesive portions are affixed, based on the mark.

[0013] The protective sticker thus constructed can position the object to be protected in the area where the object is to be protected by using the mark on the release paper to align the object to be protected with respect to the base material. Furthermore, when the protective sticker is positioned with respect to the object to be protected using the mark, the adhesive portion of the protective sticker from which the release paper has been peeled off can be affixed to the object to be protected and the object to which it is to be affixed. This makes it easy to position the protective sticker with respect to the object to be protected and the object to which it is to be affixed.

[0014] From another viewpoint, the protective sticker of the present invention preferably includes the following configuration: the release paper is coated with a release agent containing silicone, the base material is made of polyethylene terephthalate, and adheres to the object by electrostatic force of static electricity generated when the base material is peeled off from the release paper.

[0015] In the above-mentioned configuration, the base material adheres to the object to be protected and the object to be affixed by the electrostatic force generated by the electrostatic charge generated when the base material is peeled off from the release paper. Therefore, the protective sticker maintains the position of the photo relative to the protective film and the position of the object to be affixed relative to the protective film by the electrostatic force. This makes it difficult for the protective film to sag or for a gap to occur between the object to be protected and the object to be affixed, and makes it easy to position the protective film relative to the object to be protected and the object to be affixed.

[0016] From another viewpoint, the protective sticker of the present invention preferably includes the following configuration: The outer edge of each of the plurality of adhesive portions is spaced a predetermined distance from the outer edge of the base material.

[0017] In the above-mentioned configuration, the outer edge of the substrate is located outward from the outer edges of the adhesive portions. Therefore, even if the adhesive portions spread along the surface of the substrate by a pressing force from a direction perpendicular to the surface of the substrate, they do not protrude outward from the outer edge of the substrate. This prevents the adhesion of foreign matter to the adhesive portions protruding from the substrate after application, and maintains the aesthetic appearance of the protective seal.

[0018] From another viewpoint, the protective sticker of the present invention preferably includes the following configuration: an adhesion suppressing layer is applied to a surface of the adhesive portion, the adhesion suppressing layer covers a portion of the surface of the adhesive portion other than a portion that exerts adhesive force as the plurality of adhesive portions.

[0019] In the above-mentioned configuration, the adhesive layer laminated on one side of the base material is divided into a plurality of adhesive portions, which are portions having adhesive force, and a portion having no adhesive force, by the applied adhesive suppression layer. Since the adhesive layer does not have an adhesive suppression film or the like attached to suppress the adhesive force, peeling of the adhesive suppression film does not occur when the adhesive layer is attached to the object to be protected and the portion to be attached. In addition, the adhesive layer is thinner than when the adhesive portion is formed by an adhesive suppression film. This makes it easy to position the adhesive layer relative to the object to be protected and the portion to be attached.

[0020] According to another aspect, the protective sticker of the present invention preferably includes the following configuration: A printed layer for decorating the object to be protected is provided on the other surface of the base material and is positioned in an area where the object to be protected is to be protected.

[0021] According to the above-mentioned configuration, the base material not only protects the object to be protected, but also decorates the object to be protected located in the area where the object to be protected is protected by the printing layer. As a result, the protective sticker can display characters, figures, etc. as decoration by superimposing them on the object to be protected that is attached to the affixed object by the printing layer.

[0022] From another viewpoint, the protective seal of the present invention preferably includes the following configuration: The base material includes an ultraviolet absorbing agent.

[0023] According to the above-mentioned configuration, the protective seal covers the object to be protected with a base material, thereby preventing the occurrence of scratches, etc. on the object to be protected, and by absorbing ultraviolet rays, it is possible to prevent discoloration, deterioration, etc. of the object to be protected caused by ultraviolet rays.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The positioning device according to the present invention will be described below with reference to the drawings. In each drawing, the same parts are given the same reference numerals, and the description of the same parts will not be repeated. The dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components and the dimensional ratios of each component.

[0033] [Embodiment 1] <Protection seal 1 composition> A protective seal 1 according to a first embodiment of the protective seal of the present invention will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a plan view of the protective seal 1 according to the first embodiment of the present invention, seen from the direction in which the adhesive layer 3 is laminated. Fig. 2 is a side view of the protective seal 1.

[0034] As shown in Figs. 1 and 2, the protective sticker 1 is a sticker that protects a photograph P, which is an object to be protected. The protective sticker 1 protects a photograph P (see Fig. 3) in a state where it is affixed to a smartphone S (see Fig. 3), which is an object to which the protective sticker 1 is to be affixed. In this embodiment, the photograph P is a print photograph taken with an instant camera and printed on a rectangular photographic paper. The protective sticker 1 has a protective film 2, which is a base material, an adhesive layer 3, and an adhesion suppressing layer 4.

[0035] The protective film 2 protects the photograph P. The protective film 2 is, for example, a transparent resin film. The protective film 2 has a thickness of, for example, about 30 to 100 μm. The protective film 2 is formed in a rectangular shape. The protective film 2 has an area larger than the area of ​​the photograph P, and has a shape capable of covering the entire surface of the photograph P. In this embodiment, the length of the long side of the protective film 2 is longer than the length of the long side of the photograph P. In addition, the length of the short side of the protective film 2 is longer than the length of the short side of the photograph P.

[0036] Protective film 2 covers the entire surface of photograph P positioned in a region (hereinafter simply referred to as "protective region X") where photograph P is protected, which is the center in the long-side direction and the center in the short-side direction of protective film 2, in a predetermined posture in which the long sides of photograph P and protective film 2 are parallel and the surface of photograph P and the surface of protective film 2 are parallel. In other words, protective film 2 can protect the entire surface of photograph P positioned in protective region X in a predetermined posture.

[0037] The adhesive layer 3 attaches the protective film 2 to the photo P and the smartphone S. The adhesive layer 3 is formed of an adhesive. The adhesive layer 3 has an adhesive strength that allows the protective film 2 and the photo P to be maintained in a state of being attached to the smartphone S. The adhesive layer 3 also has an adhesive strength that allows the adhesive layer 3 to be peeled off from the object to which it is attached, including the photo P and the smartphone S, without damaging the object. Specifically, the adhesive layer 3 has an adhesive strength of, for example, about 2N / 10mm to 10N / 10mm. The adhesive layer 3 is composed of, for example, a rubber-based adhesive, an acrylic-based adhesive, a silicone-based adhesive, a urethane-based adhesive, or the like.

[0038] The adhesive layer 3 is located over the entire surface of one side of the protective film 2. In other words, the adhesive layer 3 is a layer of adhesive that covers the entire surface of one side of the protective film 2. The adhesive layer 3 is configured with two adhesive portions, a first adhesive portion 31 and a second adhesive portion 32, by an adhesion suppressing layer 4 laminated on the surface of the adhesive layer 3 (see the hatched portion in FIG. 1). The first adhesive portion 31 and the second adhesive portion 32 are each configured as an independent and separate region.

[0039] The adhesion suppressing layer 4 suppresses the adhesion of the adhesive layer 3. The adhesion suppressing layer 4 is formed by a known transparent topcoat such as an ultraviolet curing varnish. The adhesion suppressing layer 4 does not have adhesion. Therefore, the adhesion suppressing layer 4 suppresses the adhesion of the adhesive layer 3 by covering the adhesive layer 3. The adhesion suppressing layer 4 is applied to a part of the surface of the adhesive layer 3, not the entire surface (see the light black part in FIG. 1). The adhesion suppressing layer 4 is located in a part of the adhesive layer 3 that does not need to be attached to the photo P and the smartphone S. In other words, the adhesion suppressing layer 4 divides the adhesive layer 3 into a part that needs adhesion and a part that does not need adhesion. In this embodiment, the adhesion suppressing layer 4 covers a part of the adhesive layer 3, thereby forming a plurality of adhesive parts each having adhesion. In the protective sticker 1, the thickness of the adhesive layer 3 including the adhesion suppressing layer 4 described above is adjusted to be 10 μm to 30 μm.

[0040] The adhesive layer 3 is configured with a first adhesive portion 31 and a second adhesive portion 32, which are a plurality of adhesive portions, by the adhesion-suppressing layer 4. The first adhesive portion 31 and the second adhesive portion 32 are parts of the adhesive layer 3 that are not covered by the adhesion-suppressing layer 4. The adhesive layer 3 is covered by the adhesion-suppressing layer 4 in all parts other than the first adhesive portion 31 and the second adhesive portion 32. In other words, in the adhesive layer 3, only the first adhesive portion 31 and the second adhesive portion 32 have adhesive force.

[0041] The first adhesive portion 31 is located at one end of the protective film 2 in the long side direction. The second adhesive portion 32 is located at the other end of the protective film 2 in the long side direction. The first adhesive portion 31 and the second adhesive portion 32 are each configured in a rectangular range extending along the short side of the protective film 2. In this manner, the first adhesive portion 31 and the second adhesive portion 32 are configured in a plurality of portions at different positions on one surface of the protective film 2. Furthermore, the width of the first adhesive portion 31 and the second adhesive portion 32 in the long side direction of the protective film 2 is set to, for example, about 5 mm.

[0042] A part of the first adhesive portion 31 is arranged at a position overlapping one end of the protective area X when viewed in a direction perpendicular to one surface of the protective film 2. That is, a part of the range of the first adhesive portion 31 is included in the protective area X. The range of the first adhesive portion 31 included in the protective area X functions as a first photo adhesive area 31a to which the photo P positioned in the protective area X is attached. Similarly, a part of the second adhesive portion 32 is arranged at a position overlapping the other end of the protective area X when viewed in a direction perpendicular to one surface of the protective film 2. That is, a part of the range of the second adhesive portion 32 is included in the protective area X. The range of the second adhesive portion 32 included in the protective area X functions as a second photo adhesive area 32a to which the photo P positioned in the protective area X is attached.

[0043] The area of ​​the first adhesive portion 31 other than the first photo adhesive area 31a functions as a first object adhesive area 31b to be attached to the back surface of the smartphone S. Similarly, the area of ​​the second adhesive portion 32 other than the second photo adhesive area 32a functions as a second object adhesive area 32b to be attached to the back surface of the smartphone S.

[0044] The protective sticker 1 thus configured has an adhesive layer 3, which is formed of a first adhesive portion 31 and a second adhesive portion 32 and is formed by an adhesive force suppressing layer 4, located on one surface of the protective film 2. The protective sticker 1 can attach the protective film 2 to a photo P or a smartphone S by the first adhesive portion 31 and the second adhesive portion 32.

[0045] <How to use protective sticker 1> Next, a method for attaching a photograph P to the back surface of a smartphone S using a protective sticker 1 will be described with reference to Figures 1 and 3. Figure 3 is a side view showing a state in which the protective sticker 1 is attached to a photograph P on the back surface of the smartphone S.

[0046] As shown in FIG. 3, the protective sticker 1 is positioned relative to the photo P so that, for example, a photo P placed at an arbitrary position on the back of the smartphone S is located in the protective area X of the protective film 2 (see FIG. 1). The protective sticker 1 is positioned so that the protective area X overlaps the photo P in a predetermined posture when viewed in a direction perpendicular to one surface of the protective film 2 with one surface of the protective film 2 facing the image surface on which the image of the photo P is displayed. At this time, one end of the long side direction of the photo P overlaps the first photo adhesive area 31a of the first adhesive portion 31 when viewed in a direction perpendicular to one surface of the protective film 2. The other end of the long side direction of the photo P overlaps the second photo adhesive area 32a of the second adhesive portion 32 when viewed in a direction perpendicular to one surface of the protective film 2 (see FIG. 1).

[0047] The first photo adhesive area 31a of the first adhesive portion 31 is attached to one end of the long side of the photo P. The second photo adhesive area 32a of the second adhesive portion 32 is attached to the other end of the long side of the photo P. The first photo adhesive area 31a and the second photo adhesive area 32a are attached to a frame portion surrounding the image in the photo P. Therefore, the first adhesive portion 31 and the second adhesive portion 32 do not reduce the visibility of the photo P or damage the image portion of the photo P due to their adhesive force.

[0048] The protective sticker 1 holds the photograph P in a predetermined position in the protective area X by the first adhesive portion 31 and the second adhesive portion 32. Moreover, the protective sticker 1 does not hold the photograph P by any portion other than the first adhesive portion 31 and the second adhesive portion 32. At this time, the protective film 2 covers the entire surface of the photograph P positioned in the protective area X.

[0049] Next, the protective sticker 1 is attached to the back of the smartphone S together with the photo P. The protective sticker 1 is attached to the back of the smartphone S with the photo P attached to the first photo adhesive area 31a of the first adhesive portion 31 and the second photo adhesive area 32a of the second adhesive portion 32. In the first adhesive portion 31, the first object adhesive area 31b, which is the area where the photo P is not attached, is attached to the wall of the smartphone S. In the second adhesive portion 32, the second object adhesive area 32b, which is the area where the photo P is not attached, is attached to the wall of the smartphone S. That is, a part of the photo P and a part of the smartphone S are attached to the first adhesive portion 31 and the second adhesive portion 32, respectively. In this way, the protective sticker 1 is attached to the back of the smartphone S in a state where it is positioned relative to the photo P. On the other hand, the parts of the protective film 2 other than the parts where the first adhesive portion 31 and the second adhesive portion 32 are located are not attached to the photo P and the smartphone S.

[0050] Furthermore, the protective sticker 1 maintains the state of the protective film 2 attached to the photograph P due to the rigidity of the photograph P attached to the first adhesive portion 31 and the second adhesive portion 32. Therefore, when the protective sticker 1 is attached to the smartphone S, sagging, twisting, wrinkles, etc. do not occur, and the first adhesive portion 31 and the second adhesive portion 32 do not stick to each other.

[0051] In the protective sticker 1 thus configured, the adhesive layer 3 is divided by the adhesive suppression layer 4 into a first adhesive portion 31 and a second adhesive portion 32, which are portions having adhesive force, and a portion having no adhesive force. Therefore, the adhesive layer 3 does not need to be covered with an adhesive suppression film or the like for suppressing adhesive force, and therefore the adhesive suppression film does not peel off when the protective sticker 1 is attached to the photo P and the smartphone S. In addition, the protective sticker 1 is thinner than when the first adhesive portion 31 and the second adhesive portion 32 are configured with an adhesive suppression film.

[0052] Furthermore, the protective sticker 1 has the photo P attached to the first photo adhesive area 31a and the second photo adhesive area 32a, and is attached to the back surface of the smartphone S by the first object adhesive area 31b and the second object adhesive area 32b. That is, the protective sticker 1 is attached to the photo P and to the smartphone S only by the first adhesive part 31 and the second adhesive part 32. This makes it easy to position the protective sticker 1 relative to the photo P having a predetermined shape and to the smartphone S.

[0053] In addition, the protective sticker 1 is configured to allow air to pass between the photograph P and the smartphone S and between the portions of the protective film 2 other than the portions where the first adhesive portion 31 and the second adhesive portion 32 are located, so that no air pockets are formed between the protective film 2 and the photograph P, or between the protective film 2 and the smartphone S. This allows the protective sticker 1 to be easily attached to the photograph P and the smartphone S.

[0054] 1 and 4, the protective sticker 1 may be attached to the back of the smartphone S together with the photo P by the first object adhesive area 31b and the second object adhesive area 32b, with the photo P attached to the first photo adhesive area 31a and the second photo adhesive area 32a. The protective sticker 1 positions the photo P in a predetermined posture in the protection area X with respect to the protective film 2. One end of the long side of the photo P is attached to the first photo adhesive area 31a. The other end of the long side of the photo P is attached to the second photo adhesive area 32a (see FIG. 1).

[0055] The protective sticker 1 with the photo P attached thereto is positioned at an arbitrary position relative to the smartphone S. The protective sticker 1 is attached to the back of the smartphone S by the first attachment adhesive area 31b and the second attachment adhesive area 32b. At this time, the first adhesive portion 31 and the second adhesive portion 32 located at both ends of the protective film 2 are positioned relative to the photo P. That is, the relative positions of the first adhesive portion 31 and the second adhesive portion 32 of the protective sticker 1 are maintained by the photo P. Therefore, when the protective sticker 1 is attached to the smartphone S together with the photo P, the first adhesive portion 31 and the second adhesive portion 32 are not attached to each other, making it easier to handle. In addition, the thinner the protective sticker 1 is, the stronger the sense of unity between the protective sticker 1 and the photo P and further the smartphone S becomes. This improves the appearance of the smartphone S to which the photo P is attached.

[0056] [Modification 1 of the first embodiment] A protective sticker 1A according to a first modified example of the first embodiment of the protective sticker of the present invention will be described below with reference to Fig. 5 to Fig. 7. Fig. 5 is a plan view of the protective sticker 1A according to the first modified example of the present invention, seen from the direction in which the release paper 5 is located. Fig. 6 is a side view of the protective sticker 1A. Fig. 7 is a side view showing the protective sticker 1A attached to a smartphone S together with a photograph P.

[0057] The protective sticker 1A differs from the protective sticker 1 in that it has a release paper 5. In the following modified examples, the same components as those in the first embodiment are given the same reference numerals and their explanations are omitted, and only the parts that differ from the first embodiment are explained.

[0058] <Configuration of protective seal 1A> As shown in FIGS. 5 and 6, the protective sticker 1A has a protective film 2, an adhesive layer 3, an adhesion-suppressing layer 4, and a release paper 5.

[0059] The release paper 5 protects the protective region X of the protective film 2 and the first adhesive portion 31 and the second adhesive portion 32 of the adhesive layer 3. The release paper 5 is a paper substrate, and one side of the release paper 5 is coated with a known release agent, for example, including silicone. This allows the release paper 5 to be attached to the adhesive layer 3 and peeled off from the adhesive layer 3 while maintaining the adhesive state of the adhesive layer 3. The release paper 5 covers at least the first adhesive portion 31 and the second adhesive portion 32. In this embodiment, the release paper 5 is formed in the same shape as the protective film 2. The release paper 5 covers the entire surfaces of the adhesive layer 3 and the adhesion suppressing layer 4 with the first adhesive portion 31 and the second adhesive portion 32 attached to the surface coated with the release agent.

[0060] The release paper 5 is divided into a first partition 51 including a portion attached to the first photo adhesive area 31a and the second adhesive area 32 of the first adhesive portion 31, and a second partition 52 including a portion attached to the first object adhesive area 31b of the first adhesive portion 31. In this embodiment, the release paper 5 is divided into the first partition 51 and the second partition 52 by the boundary between the first photo adhesive area 31a and the first object adhesive area 31b. The release paper 5 can peel off the first partition 51 and the second partition 52 separately from the adhesive layer 3. This allows the protective sticker 1A to be in a state where either the first adhesive portion 31 or the second adhesive portion 32 exerts adhesive force.

[0061] The release paper 5 has a mark Y on the other side, on which no release agent is applied, for positioning the photograph P in a predetermined orientation in the protective area X. In this embodiment, the mark Y indicates the position of the outer edge of one end in the long side direction of the photograph P positioned in the protective area X. When viewed in a direction perpendicular to one side of the protective film 2, the mark Y overlaps at least one of the first adhesive portion 31 and the second adhesive portion 32. The mark Y also indicates at least one of the boundary between the first photograph adhesive area 31a and the first object adhesive area 31b in the first adhesive portion 31 and the boundary between the second photograph adhesive area 32a and the second object adhesive area 32b in the second adhesive portion 32.

[0062] In this embodiment, the mark Y indicates the boundary between the first photographic adhesive area 31a and the first object adhesive area 31b. Therefore, the dividing line between the first partition 51 and the second partition 52, which is divided at the boundary between the first photographic adhesive area 31a and the first object adhesive area 31b, functions as the mark Y.

[0063] <How to use the protective seal 1A> Next, a method for attaching a photograph P to the back surface of a smartphone S using a protective sticker 1A will be described with reference to Fig. 7. Fig. 7 is a side view showing a state in which the protective sticker 1A is attached to the smartphone S together with a photograph P. The photograph P is placed on the back surface of the smartphone S.

[0064] 7, in the protective sticker 1A, the first partition 51 of the release paper 5 is peeled off from the protective film 2 (see the first and second steps in FIG. 7). As a result, the protective sticker 1A is in a state in which the second partition 52 of the release paper 5 is affixed to the first object adhesive area 31b. In addition, the outer edge of the second partition 52 on the first partition 51 side represents the outer edge of the first photo adhesive area 31a, which indicates the position of the outer edge of the end in the long side direction of the photo P located in the protective area X as a mark Y.

[0065] The protective sticker 1A is arranged so that the mark Y, which is the outer edge of the second partition 52, overlaps with the outer edge of one end of the long side of the photo P arranged on the back of the smartphone S at approximately the center of the short side of the protective film 2. As a result, the photo P is positioned in a predetermined posture in the protective area X of the protective sticker 1A. At this time, the first photo adhesive area 31a of the protective sticker 1A overlaps with one end of the long side of the photo P when viewed in a direction perpendicular to one surface of the protective film 2. The second photo adhesive area 32a of the protective sticker 1A overlaps with the other end of the long side of the photo P when viewed in a direction perpendicular to one surface of the protective film 2.

[0066] Next, the first photo adhesive area 31a of the protective sticker 1A is attached to one end of the long side direction of the photo P, and the second photo adhesive area 32a is attached to the other end of the photo P. Furthermore, the second object adhesive area 32b of the protective sticker 1A is attached to the smartphone S (see the third step in FIG. 7). The protective sticker 1A is positioned relative to the photo P using the mark Y as a reference, and is attached to the photo P and the smartphone S with the photo P located in the protection area X.

[0067] Next, the second partition portion 52 of the release paper 5 of the protective sticker 1A is peeled off from the first object adhesive area 31b (see the fourth step in FIG. 7). At this time, the protective sticker 1A is attached to the photograph P and the smartphone S, so that the position of the protective sticker 1A relative to the photograph P and the smartphone S is maintained. Next, the first object adhesive area 31b of the protective sticker 1A is attached to the smartphone S (see the fifth step in FIG. 7).

[0068] The protective sticker 1A configured in this manner can position the photo P in the protection area X by utilizing the mark Y, which is the dividing line between the first partition 51 and the second partition 52, to align the photo P. Furthermore, since the outer edge of the second partition 52, which is the dividing line of the release paper 5, functions as the mark Y, the protective sticker 1A can be visually recognized from the side of the protective film 2 on which the first adhesive portion 31 and the second adhesive portion 32 are not applied. This makes it easy to position the protective sticker 1A relative to the photo P and the smartphone S. Furthermore, the protective sticker 1A can be easily attached to the smartphone S together with the photo P.

[0069] [Modification 2 of the first embodiment] A protective seal 1B according to a second modification of the first embodiment of the protective seal of the present invention will be described below with reference to Fig. 8. Fig. 8 is a side view showing a state in which a photograph P is adhered to the protective seal 1B according to the second modification of the present invention by electrostatic force.

[0070] The protective seal 1B differs from the protective seal 1A in that the protective film 2B is made of polyethylene terephthalate.

[0071] <Configuration of protective seal 1B> As shown in FIG. 8, the protective sticker 1B has a protective film 2B, an adhesive layer 3, an adhesion-suppressing layer 4, and a release paper 5 having a paper base.

[0072] The protective film 2B protects the photograph P. The protective film 2B is made of transparent polyethylene terephthalate (hereinafter simply referred to as "PET") The protective film 2B is, for example, a film having a thickness of about 30 to 70 μm.

[0073] Since PET is an insulator, the PET protective film 2B is charged with, for example, negative static electricity due to peeling electrification when peeled off from the release paper 5. The electrostatically charged protective film 2B generates an electrostatic force (Coulomb force) against the paper photograph P, which is more easily charged with positive static electricity than PET.

[0074] <How to use the protective seal 1B> In the protective sticker 1B, the release paper 5 is peeled off from the first adhesive portion 31 and the second adhesive portion 32. The protective film 2B is negatively charged with static electricity due to peeling electrification (see the first and second steps, which are the most upstream steps in FIG. 8).

[0075] Next, protective sticker 1B is placed on photo P so that photo P is located in protective area X (see the third step in FIG. 8). At this time, protective film 2B, which is negatively charged, is attracted to the positive charge of photo P by electrostatic force and adheres to photo P. Therefore, protective sticker 1B is positioned by electrostatic force in a state in which photo P is located in protective area X.

[0076] Next, in a state in which the photograph P is positioned in the protection area X by electrostatic force, the first adhesive portion 31 is attached to one end in the long side direction of the photograph P positioned in the protection area X and to the smartphone S. Similarly, the second adhesive portion 32 is attached to the other end in the long side direction of the photograph P and to the smartphone S (see the fourth step in FIG. 8). At this time, the portion of the protective film 2B where the first adhesive portion 31 and the second adhesive portion 32 are not positioned and which is not in contact with the photograph P is in contact with the back surface of the metallic smartphone S which is more easily charged with positive static electricity than PET by electrostatic force.

[0077] Therefore, when the first adhesive portion 31 and the second adhesive portion 32 of the protective sticker 1B are attached to the photograph P and the smartphone S, sagging of the protective film 2B and gaps between the protective film 2B and the photograph P and the smartphone S are unlikely to occur. This makes it easy to position the protective sticker 1B relative to the photograph P and the smartphone S. In addition, the protective sticker 1B can be easily attached to the smartphone S together with the photograph P.

[0078] [Modification 3 of embodiment 1] A protective seal 1C according to a third modification of the first embodiment of the protective seal of the present invention will be described below with reference to Fig. 9. Fig. 9 is a plan view of the protective seal 1C in the third modification of the present invention as viewed from the direction in which the adhesive layer 3 is laminated.

[0079] The protective sticker 1C differs from the protective sticker 1 in the arrangement of the first adhesive portion 31C and the second adhesive portion 32C of the adhesive layer 3 relative to the protective film 2.

[0080] <Configuration of protective seal 1C> As shown in FIG. 9, the protective sticker 1C has a protective film 2, an adhesive layer 3, and an adhesion-suppressing layer 4 (see FIG. 3).

[0081] The adhesive layer 3 is configured with an adhesion suppressing layer 4 laminated on the surface of the adhesive layer 3 to form a plurality of adhesive portions, that is, a first adhesive portion 31C and a second adhesive portion 32C.

[0082] The first adhesive portion 31C is located at one end of the protective film 2 in the long side direction. The second adhesive portion 32C is located at the other end of the protective film 2 in the long side direction. The first adhesive portion 31C and the second adhesive portion 32C are each configured in a rectangular range extending along the short side of the protective film 2. The outer edge of the first adhesive portion 31C and the outer edge of the second adhesive portion 32C are spaced a predetermined amount Z away from the outer edge of the protective film 2. In other words, the protective film 2 extends outward from the outer edge of the first adhesive portion 31C and the outer edge of the second adhesive portion 32C by the predetermined amount Z.

[0083] When an external force perpendicular to the surface of the protective film 2 is applied to the protective sticker 1C while it is attached to the smartphone S, the first adhesive portion 31C and the second adhesive portion 32C are pushed and spread along the surface of the protective film 2. At this time, since the outer edge of the protective film 2 is separated from the outer edge of the first adhesive portion 31C and the outer edge of the second adhesive portion 32C, the first adhesive portion 31C and the second adhesive portion 32C do not protrude from the protective film 2 even if they are pushed and spread. This prevents the attachment of foreign matter to the first adhesive portion 31C and the second adhesive portion 32C that protrude from the protective film 2 due to an external force after attachment of the protective sticker 1, and allows the protective sticker 1 to maintain its beautiful appearance.

[0084] [Other embodiments] In the above-mentioned embodiments, the protective stickers 1, 1A, 1B, and 1C cover the photograph P with the transparent protective films 2 and 2B. Therefore, the protective stickers 1, 1A, 1B, and 1C allow the photograph P, including the photographic paper and the image displayed on the photographic paper, to be viewed in its entirety through the protective film 2. However, as shown in FIG. 10, the protective sticker 1D may have a printed layer 6 for decorating the photograph P on the surface of the protective film 2 on which the adhesive layer 3 is not located. FIG. 10 is a plan view of the protective sticker 1D in another embodiment of the present invention as viewed from the direction in which the printed layer 6 is laminated, and a plan view showing the state in which the protective sticker 1D is attached to the photograph P.

[0085] As shown in FIG. 10, the printed layer 6 of the protective sticker 1D includes characters, decorative characters, figures, photographs, holograms, etc. of any color that decorate the photograph P positioned in the protective area X. The printed layer 6 is located on the other side of the protective film 2. The printed layer 6 is, for example, a layer on which a known paint is baked to display characters, figures, etc. on the other side of the protective film 2. The printed layer 6 is, for example, a layer that has been subjected to hologram processing to display characters, figures, etc. in a three-dimensional manner. The hologram is formed by transferring a hologram pattern of a film that has been previously hologram-processed to a water-soluble resin such as polyvinyl alcohol that is applied to the protective film 2.

[0086] The protective sticker 1D can hide a part of the photograph P covered by the protective film 2 by the printed layer 6. The protective sticker 1D can also decorate the photograph P by the printed layer 6. This allows the protective sticker 1D to improve the decorativeness of the photograph P.

[0087] In each of the above-mentioned embodiments, the protective seals 1, 1A, 1B, and 1C cover the photograph P with a transparent protective film 2. Therefore, even if the photograph P is protected by the protective seals 1, 1A, 1B, and 1C, it is deteriorated by ultraviolet rays and the like that pass through the protective film 2. Therefore, the protective seal may be composed of a protective film that contains an ultraviolet absorbing agent or the like, or a protective film to which an ultraviolet absorbing agent or the like is applied. In this way, the protective seal can cover the object to be protected with the protective film, thereby preventing scratches and the like from occurring on the object to be protected, and can prevent discoloration, deterioration, and the like of the object to be protected caused by ultraviolet rays and the like by absorbing ultraviolet rays and the like.

[0088] In the above-described embodiments, the protective stickers 1, 1A, 1B, and 1C cover the photograph P with a transparent protective film 2. However, the protective film may be a colored protective film. The protective film may be any film that allows the object to be protected that is covered by the protective film to be visually recognized.

[0089] In the above-described embodiments, the protective stickers 1, 1A, 1B, and 1C cover the photograph P with the rectangular protective film 2. However, the protective film may have any shape as long as it can cover the object to be protected. The protective film may be, for example, a circle, an ellipse, a square, a star, or the like.

[0090] Furthermore, in each of the above-described embodiments, the adhesive layer 3 of the protective stickers 1, 1A, 1B, and 1C is configured with the first adhesive portion 31 and the second adhesive portion 32 by applying the adhesion-suppressing layer 4 to a portion of the adhesive layer 3. However, the adhesive layer may be configured with a plurality of adhesive portions by attaching an adhesion-suppressing film to a portion of the adhesive layer.

[0091] In each of the above-mentioned embodiments, the adhesive layer 3 of the protective stickers 1, 1A, 1B, and 1C is coated with an adhesive force suppressing layer 4 on a portion of the adhesive layer 3, thereby forming a rectangular first adhesive portion 31 and a second adhesive portion 32 at both ends in the longitudinal direction of the protective film 2. However, the multiple adhesive portions may be in any position and shape that allows them to be attached to a portion of the object to be protected and a portion of the object to be attached. In other words, the multiple adhesive portions may be in a shape other than rectangular. Furthermore, the multiple adhesive portions do not have to be at both ends of the protective film.

[0092] In each of the above-mentioned embodiments, the adhesive layer 3 of the protective stickers 1, 1A, 1B, and 1C is coated with an adhesive suppression layer 4 on a portion of the adhesive layer 3, thereby forming a rectangular first adhesive portion 31 and a second adhesive portion 32 at both ends of the longitudinal direction of the protective film 2. However, the multiple adhesive portions may be configured by applying an adhesive to a position on the protective film where adhesive force is desired to be generated. For example, the multiple adhesive portions are configured by applying an adhesive to a portion of the object to be protected arranged in the protective region X and an area where the adhesive can be attached to the object to be attached, without using an adhesive suppression layer.

[0093] In each of the above-described embodiments, the first adhesive portion 31 and the second adhesive portion 32 of the protective stickers 1, 1A, 1B, and 1C are attached to the photo P and the smartphone S, respectively. However, the multiple adhesive portions may be configured at positions where they are attached to either the object to be protected or the object to be affixed. Some of the multiple adhesive portions are, for example, affixed only to the object to be protected. Also, some of the multiple adhesive portions are, for example, affixed only to the object to be affixed.

[0094] In the above-described embodiments, the protective stickers 1, 1A, 1B, and 1C are attached to the smartphone S as a protective film 2 having a photo P attached thereto. However, the protective stickers may be used to attach a photo, which is an object to be protected, to the paper surface of a booklet, which is an object to be attached. The protective stickers can be used to create an album by holding photos.

[0095] In the above-mentioned second embodiment, the release paper 5 of the protective sticker 1A has a dividing line as a mark Y indicating the outer edge of the end in the long side direction of the photograph P when the photograph P is positioned in the protection area X. However, the mark for positioning the object to be protected in the specified protection area may be configured to be capable of positioning the object to be protected, such as by printing, embossing, or cutting. Furthermore, the mark does not have to be a mark indicating the position to position the object to be protected. The mark may be, for example, a square in which a plurality of equally spaced lines intersect at right angles. Furthermore, the mark may be configured on an adhesive layer.

[0096] In the above-described second embodiment, the release paper 5 of the protective sticker 1A is cut into a first partition 51 and a second partition 52. However, it is sufficient that the release paper is configured so that only one of the first partition and the second partition can be peeled off. The release paper may be configured so that it can be cut into the first partition and the second partition by, for example, a perforation, a half cut, or the like.

[0097] In the above-described third embodiment, the protective sticker 1B covers the photograph P with a protective film 2B made of transparent polyethylene terephthalate. However, the protective film does not have to be made of transparent polyethylene terephthalate. The protective film may be any material that generates an electrostatic force due to peeling electrification.

[0098] Although the embodiment of the present invention has been described above, the above-mentioned embodiment is merely an example for carrying out the present invention. Therefore, the present invention is not limited to the above-mentioned embodiment, and it is possible to carry out the above-mentioned embodiment by appropriately modifying it within the scope of the gist of the present invention.
