Sheet for attaching a protective sheet to a display screen and sheet attaching system for attaching the protective sheet
[0001] The present invention relates to a sheet for attaching a protective sheet to a display screen of a mobile device, and an attachment system for attaching the protective sheet.
[0002] Mobile devices such as mobile phones, including iPhones (registered trademarks), are equipped with display screens made of liquid crystal, inorganic or organic electroluminescence (EL), or the like. Because display screens are susceptible to scratches during use, they are protected with resin films such as PET. Such protective films are applied to the display screen by peeling off the release sheet to expose the adhesive portion, but this can lead to problems such as inaccurate application positioning and the formation of air bubbles. Furthermore, when the patch layer is touched by fingers, sebum can reduce the adhesive strength.
[0003] However, while conventional attachment aids can attach flexible, bendable resin films such as PET, they cannot attach hard glass sheets, which allow for some bending, to display screens without misalignment because the hard sheets cannot be bent like PET or other resin films.
[0004] In order to solve these problems, Japanese Patent Application Laid-Open No. 2021-43283 discloses a sheet attachment system having "a main body for fixing a mobile device having a display screen, a protective sheet that is attached to the display screen and has a shape similar to that of the display screen to protect the display screen, and a positioning sheet that determines the position at which the protective sheet is attached to the display screen, wherein the main body has a first protrusion that stands upward and a second protrusion that stands upward, and the positioning sheet has a first hole that is swingably engaged with the first protrusion and a second hole that fits into the second protrusion, the protective sheet is removably attached below the positioning sheet, the first hole is swingably placed on the first protrusion and the second hole fits into the second protrusion, so that both the positioning sheet and the protective sheet are arranged at an angle to the main body in a side view."
[0005] While the above-mentioned sheet application system has been well-received by users, it is necessary to minimize the possibility of dust intrusion when applying the protective sheet to the display screen. For example, the process of applying the protective sheet to the display screen of an electronic device such as a smartphone involves wiping off sebum stains and dust with a cleaning cloth or the like, but even after applying the protective sheet to the display screen, dust can still find its way between the protective sheet and the display screen. Furthermore, the need to open and close the cover and place the protective sheet over the display screen is inconvenient.

[0015] This example will be described below with reference to the illustrated embodiment. The sheet 10 of this example is for protecting a display screen 500 of a mobile device 600 such as a smartphone, and includes a dust removal sheet 20 that is temporarily attached to the display screen 500 to remove dust that has adhered to the display screen 500, a protective sheet 40 that has an adhesive portion 30 that is attached to the display screen 500 to protect the display screen 500, and a removable release sheet 60 that is attached to the adhesive portion 30 and protects the adhesive portion 30. The adhesive portion 30 is preferably a silicone adsorption layer.
[0016] The sheet 10 of this embodiment also has a drawer 80. The drawer 80 is attached to the dust collection sheet 20 and the release sheet 60, and as will be described later, pulling the drawer 80 allows the dust collection sheet 20 and the release sheet 60 to be pulled out at the same time. The dust collection sheet 20 is preferably a paper sticker, and the release sheet 60 is preferably made of PET (polyethylene terephthalate).
[0017] The sheet 10 of this embodiment also has a dust-removing adhesive portion 72 that adheres to dust on the dust-removing sheet 20, and a dust-removing peel-off sheet 90 that protects the dust-removing adhesive portion 72. This will be described later.
[0018] Since the dust removal sheet 20 is attached to the display screen 500, it preferably has the same shape as the display screen 500. In this embodiment, it is a substantially rectangular shape with rounded corners. That is, the dust removal sheet 20 has a first short side 21, a second short side 22 opposite the first short side 21, a first long side 23 perpendicular to the first short side 21, and a second long side 24 opposite the first long side 23, resulting in a plurality of rounded corners 26. The dust removal sheet 20 also has a dust removal adhesive portion 72 that adheres to the back surface 71, and the dust removal adhesive portion 72 is used to remove dust adhering to the screen 500 by causing it to adhere to the dust removal adhesive portion 72.
[0019] The first short side 21 of the dust removal sheet 20 has a rectangular attachment portion 28 that protrudes outward from the first short side 21. Note that the attachment portion 28 may be bent along the first short side 21, as shown in FIG.
[0020] The protective sheet 40 is preferably a thin glass plate, and preferably has the same shape as the display screen 500 so as to be attached to the display screen 500. The protective sheet 40 of this embodiment is substantially rectangular with rounded corners. That is, the protective sheet 40 has a first protective short side 41 as a short side, a second protective short side 42 opposite the first protective short side 41, a first protective long side 43 as a long side perpendicular to the first protective short side 41, and a second protective long side 44 opposite the first protective long side 43, resulting in a rounded corner portion 46.
[0021] As described above, the back surface 40a of the protective sheet 40 has an adhesive portion 30 for adhering to the display screen 500, and a release sheet 60 is removably attached to protect the adhesive portion 30. The release sheet 60 has substantially the same shape as the protective sheet 40, except for the release attachment portion 68 described below. Therefore, the release sheet 60 has a substantially rectangular shape, including a first release short side 61, a second release short side 62 opposite the first release short side 61, a first release long side 63 perpendicular to the first release short side 61, and a release rounded corner portion 66 having a rounded corner and a second release long side 64 opposite the first release long side 63. The release attachment portion 68 has a rectangular shape and is attached to protrude from the first release short side 61, forming an integral unit. As shown in FIG. 4 , the release attachment portion 68 may be folded along the first release short side 61.
[0022] As described above, the protective sheet 40 is preferably glass alone, or a combination of glass and a PET (polyethylene terephthalate) frame surrounding the glass is also preferred. Furthermore, the protective sheet 40 is preferably a combination of chemically strengthened glass and a shatterproof PET film. The adhesive portion 30 is preferably coated with a silicon adsorption layer. The release sheet 60 attached to the protective sheet 40 is preferably thin so that it can be easily removed. For example, the thickness of the release sheet 60 is preferably about 0.05 millimeters. The thickness of the protective sheet portion 40 is preferably about 0.5 millimeters.
[0023] The back surface 71 of the dust removal sheet 20 has a dust removal adhesive section 72 for temporarily attaching to the display screen 500, and the above-mentioned dust removal removable sheet 90 is removably attached to the dust removal adhesive section 72. Dust adhering to the display screen 500 can be adsorbed by the dust removal adhesive section 72.
[0024] In this way, the dust removal sheet 90 is removably attached to the back surface 71 of the dust removal sheet 20 to protect the dust removal adhesive portion 72. The dust removal sheet 90 has a dust removal sheet main body 92 having short and long sides of approximately the same size as the dust removal sheet 20, and a support portion 95 having short and long sides, which are integral and can be folded along a fold line 93 at the boundary between them. In other words, the dust removal sheet main body 92 has approximately the same shape as the dust removal sheet 20. Therefore, the dust removal sheet main body 92 of the dust removal sheet 90 is attached to the back surface of the dust removal sheet 20 so that the fold line 93 of the dust removal sheet main body 92 is aligned with the first long side 23 of the dust removal sheet 20, and the side 96 is positioned to follow the second long side 24 of the dust removal sheet 20. By folding along the fold line 93, the support section 95 is positioned to overlap the back side of the dust removal sheet main body 92 and protrude from the side 96 of the dust removal sheet 90 (see reference numeral 95 in FIGS. 3 and 4 ). In other words, when the dust removal sheet 90 is attached to the back surface 71 of the dust removal sheet 20 in this manner, the support section 95 of the dust removal sheet 90 is positioned to protrude from the first long side 23. In FIG. 4, the support portion 95 ′ shows the dust removal sheet 90 in an unfolded state without being folded along the fold line 93 , and the support portion 95 shows the dust removal sheet 90 in a folded state along the fold line 93 .
[0025] Thus, by pulling the support portion 95 of the dust removal sheet 90 attached to the dust removal sheet 20, the dust removal sheet main body 92 of the dust removal sheet 90 can be peeled off from the dust removal sheet 20. In other words, when the dust removal sheet 90 is attached to the dust removal sheet 20, the support portion 95 is positioned so as to extend beyond the second long side 24 of the dust removal sheet 20. By pulling the support portion 95 (95') extending beyond the second long side 24 in the direction of extension (Y direction), the dust removal sheet main body 92 of the dust removal sheet 90 attached to the back surface 71 of the dust removal sheet 20 can be peeled off. The dust removal sheet 90 can be divided at a dividing line 94 (see FIG. 4 ). In this case, the peel-off sheet main body 92 and the support portion 95 can each be divided into two at the dividing line 94, allowing them to be peeled off separately.
[0026] As described above, the drawer section 80 is strip-shaped and is attached to the dust collection sheet 20 and the release sheet 60. Specifically, one end 81 of the drawer section 80 is attached to the rectangular attachment section 28 of the dust collection sheet 20. The attachment section 28 is attached to the first short side 21.
[0027] One end 81 of the drawer section 80 is rectangular and is attached to the release attachment section 68 of the release sheet 60 that protrudes from the first release short side 61. The other end 82 of the drawer section 80 has a length that protrudes outward from the second short side 22 when attached to the dust removal sheet 20, and serves as a handle. The drawer section 80 is preferably made of PET (polyethylene terephthalate).
[0028] A positioning sheet 50 is attached to the surface of the protective sheet 40. The positioning sheet 50 is literally used to determine the position where the protective sheet 40 is to be attached to the display screen 500 of the mobile device 600 placed on the main body 200. The positioning sheet 50 is removably attached to the protective sheet 40. The positioning sheet 50 is preferably made of PET (polyethylene terephthalate).
[0029] The positioning sheet 50 has a first positioning short side 51, which is a short side, and a second positioning short side 52 located opposite the first positioning short side 51, and has a first positioning long side 53, which is a long side perpendicular to the first positioning short side 51, and a second positioning long side 54 located opposite the first positioning long side 53.
[0030] Furthermore, the first positioning long side 53 of the positioning sheet 50 is configured to be longer than the first protection long side 43 of the protection sheet 40. Therefore, the entire protection sheet 40 is attached to overlap with the positioning sheet 50 so as to occupy a portion of the positioning sheet 50.
[0031] The positioning sheet 50 is configured so that its longitudinal length in plan view is greater than that of a fixing portion 210 of the main body 200 (described later). The positioning sheet 50 is made of synthetic resin, preferably a single PET (polyethylene terephthalate) film. The thickness of the positioning sheet 50 is preferably about 0.2 millimeters.
[0032] Furthermore, it is preferable that the width of the positioning sheet 50 is the same as the width of the protective sheet 40. Furthermore, first holes 51a, 51a are arranged symmetrically near the first positioning short side 51, and an oval-shaped second hole 51b is arranged inside them. The first holes 51a, 51a are fitted with second protrusions 214a, 214a on the main body 200, which will be described later. The second hole 51b is fitted with a columnar portion 390 on the lid 360, which will be described later. In this way, the position of the positioning sheet 50 is determined by the main body 200 and the lid 360, and the position of the protective sheet 40 attached to the positioning sheet 50 is also determined, which in turn determines the position of a mobile device 600 placed on the main body 200, which will be described later, and the protective sheet 40.
[0033] In addition, in this way, the sheet 10 of this embodiment is integrated by attaching, from top to bottom, the positioning sheet 50, the protective sheet 40, the release sheet 60, the drawer section 80, the dust sheet 20, and the dust release sheet 90 in that order (see, for example, Figure 4).
[0034] The second positioning short side 52, which is a short side, has protrusions 55, 55 that protrude laterally from the first positioning long side 53 and the second positioning long side 54, respectively, and third hole portions 55a, 55a, which are holes, are arranged in the protrusions 55, 55.
[0035] The positioning sheet 50 also has an open positioning opening 56. The positioning opening 56 is for pressing the protective sheet 40 through the positioning opening 56, as will be described later. The area of the positioning opening 56 is preferably half or less of the area of the positioning sheet 50.
[0036] Next, the main body 200 for fixing the mobile device 600 having the display screen 500 will be described. The main body 200 is made of synthetic resin and is a case capable of housing the mobile device 600, preferably a so-called blister case. The main body 200 has a rectangular shape in a plan view. As described above, the main body 200 is made of synthetic resin and is preferably integrally molded. The main body 200 also has a fixing portion 210 having a recessed shape that conforms to the outer shape of the mobile device 600, for positioning and fixing the mobile device 600 having the display screen 500. The fixing portion 210 has a first wall portion 211, a second wall portion 212, a front end portion 213, and a rear end portion 214 that contact the mobile device 600 and are configured to be surrounded on all four sides by these. The fixing portion 210 also has a bottom surface portion 220 that is recessed further than the fixing portion 210. The fixing portion 210 has a planar shape substantially similar to that of the mobile device 600, that is, a rectangular shape with rounded corners. However, the mobile device 600 is not necessarily planar and may have irregularities. In addition, in a side view, the bottom surface portion 220 may preferably be inclined upward from the rear end portion 214 toward the front end portion 213. The front end portion 213 is connected to a wall-shaped front wall portion 213b. The main body portion 200 has a plurality of ribs 230 on its outer periphery to maintain the rigidity of the main body portion. The plurality of ribs 230 have a semicircular concave shape in a planar view.
[0037] Furthermore, the first wall surface portion 211, the second wall surface portion 212, the front end portion 213, and the rear end portion 214, which surround the four sides of the bottom surface portion 220, are configured to surround the fixing portion 210, as described above. Therefore, when an attempt is made to place the mobile device 600 on this fixing portion 210, the first wall surface portion 211, the second wall surface portion 212, the front end portion 213, and the rear end portion 214 are slightly bent as if being pushed apart by the mobile device 600, and the mobile device 600 is fixed to the main body portion 200. Furthermore, the second wall surface portion 212 is configured to be shorter in height than the first wall surface portion 211.
[0038] In addition, the bottom surface portion 220 is positioned lower than the fixed portion 210, and interference with an external camera (not shown) protruding from the rear surface of the mobile device 600 can be avoided.
[0039] As described above, the second wall surface portion 212 is configured to be lower in height than the first wall surface portion 211. Therefore, the second wall surface portion 212 has a component opening 386 that forms an opening when the lid portion 360, which will be described later, is placed over the main body portion 200. In other words, the main body portion 200 and the lid portion 360 have the component opening 386. The component opening 386 is configured to be large enough to allow the mobile device 600 to be inserted therein.
[0040] The rear end portion 214 has a hole portion 214b that is a hole with a rounded rectangular shape in a plan view between protrusion portions 214a, 214a that are approximately cylindrical and stand upright in the upward direction U. The protrusion portions 214a, 214a fit into first hole portions 51a, 51a in the positioning sheet 50. The hole portion 214b will be described later. The rear end portion 214 also has second protrusion portions 214c, 214c that are approximately columnar and stand upright in the upward direction U.
[0041] The front end 213 has long cylindrical locking portions 213a, 213a protruding upward in the upward direction U at both left and right ends thereof. The locking portions 213a, 213a are fitted into third hole portions 55a, 55a in the positioning sheet 50.
[0042] The lid 360 also includes a ceiling 370, which acts as a ceiling, and a first side wall 371, a second side wall 372, and a third side wall 373 that hang down from the ceiling 370. The first side wall 371, the second side wall 372, and the third side wall 373 surround the ceiling 370 on three sides. The fourth side wall 374 connecting the first side wall 371 and the third side wall 373 includes a recess 375, which is missing a portion of the fourth side wall 374. Therefore, when the lid 360 is placed over the main body 200 as described above, a structural opening 386 is formed between the recess 375 and the second wall 212 of the main body 200 (see, for example, FIG. 11 ). The lid 360 also includes a lid opening 380 that opens horizontally in the width direction of the ceiling 370. The drawer portion 80 projects from the lid opening 380, and the drawer portion 80 can be pulled out.
[0043] Furthermore, the lid portion 360 has a columnar columnar portion 390 that hangs down from the ceiling portion 370. The columnar portion 390 fits into the second hole portion 51b in the positioning sheet 50 of the seat portion 10, and further fits into the hole portion 214b in the main body portion 200 so as to be skewered, so to speak, and is configured to have a rectangular shape with rounded corners in a plan view so as to imitate the shape of the hole portion 214b. The lid portion 360 also has protrusion receiving portions 391 that engage with the second protrusions 214a in the main body portion 200.
[0044] The lid portion 360 also has a flange-shaped flange 393 that protrudes outward from the lower end 371a of the first side wall portion 371. Furthermore, to maintain the rigidity of the lid portion 360, the first side wall portion 371 has a plurality of first ribs 371a. The second side surface portion 372 has a plurality of second ribs 372a. The third side surface portion 373 has a plurality of third ribs 373. The plurality of first ribs 371a, the plurality of second ribs 372a, and the plurality of third ribs 373 each have a semicircular concave shape in a plan view.
[0045] The cover 360 also has a recess 395 in the ceiling 370. The recess 395 is rectangular in shape when viewed from above and has a horizontally elongated shape, and its width is preferably approximately the same as the width of the mobile device 600. The position and size (area) of the recess 395 are preferably about 5 to 10 millimeters below the top of the mobile device 600, and its vertical width is preferably 10 millimeters. The width is also preferably approximately the same as the width of the mobile device 600.
[0046] It should be noted that the sheet pasting system 800 can be made to have the main body portion 200, the sheet portion 10, and the lid portion 360, and these can be sold as a unit.
[0047] Although the component opening 386 is positioned so as to appear in the Y direction in Figure 9, it is also possible to position the opening on the opposite side, i.e., on the first wall portion 211 and the second side portion 372. In this case, by configuring the sheet 10, the main body portion 200, and the lid portion 360 to be mirror-symmetrical, the dust removal release sheet 90 can be positioned so as to follow the opposite side of the Y direction in Figure 9 (not shown).
[0048] Next, a method for using the sheet pasting system 800 will be described. The sheet 10 is placed on the main body 200 of the sheet pasting system 800 configured as described above, and the lid 360 is placed over it. As will be described later, the sheet pasting system 800 can paste the protective sheet 40 onto the display screen 500 of the mobile device 600 while the lid 360 remains over the main body 200, thereby minimizing the intrusion of dust.
[0049] As described above, in the sheet application system 800, the sheet 10 is placed on the main body 200 and the lid 360 is placed thereon. Then, the mobile device 600, from which sebum has been removed in advance from the display screen 500, is inserted through the opening 386 defined by the second wall 212 of the main body 200 and the recess 375 of the lid 360. At this time, the support portion 95 of the dust removal release sheet 90 in the sheet 10 is already positioned so as to protrude from the opening 386, and the mobile device 600 is inserted into the opening 386 so as to be positioned below the sheet 10. Note that in FIG. 10 , the mobile device 600 shown in solid lines is about to be inserted through the opening 386, while the mobile device 600 shown in dashed lines is already positioned between the main body 200 and the lid 360.
[0050] After inserting the mobile device 600 into the opening 386 configured to be positioned below the seat 10, the flange 393 protruding outward from the lower end 371 a of the first side wall 371 of the lid 360 is bent so as to wrap around the front wall 213 b of the main body 200, and the flange 393 is engaged with the lower end 371 a. In this way, the lid 360 is less likely to come off the main body 200.
[0051] Next, the support portion 95 of the dust removal release sheet 90 , which is attached to protect the dust removal adhesive portion 72 of the dust removal sheet 20 , is positioned so as to be pulled out from the component opening 386 .
[0052] The removable dust sheet main body 92 of this dust removal sheet 90 is attached to protect the dust removal adhesive portion 72 of the dust removal sheet 20, and the support portion 95 integral with the removable dust sheet main body 92 is folded back along the fold line 93, so that the support portion 95 protrudes from the opening 386. When the support portion 95 is pulled out of the opening 386, the removable dust sheet main body 92 integral with the support portion 95 is peeled off, gradually exposing the dust removal adhesive portion 72 on the back surface 71 of the dust removal sheet 20. At this time, the cover 360 is placed over the main body 200, with the sheet portion 10 and the mobile device 600 placed therein, so that dust can be prevented as much as possible from adhering to the dust removal adhesive portion 72.
[0053] When the dust removal adhesive portion 72 is exposed, the cover portion 360 is pressed from above, so that the dust removal adhesive portion 72 on the back surface 71 of the dust removal sheet 20 in the sheet portion 10 is attached to the display screen 500 .
[0054] At this time, the sheet unit 10 is placed with the cover unit 360 already placed over the main body unit 200, so there is very little chance of dust getting in between them. Furthermore, even if a small amount of dust does get in and adhere to the display screen 500, the dust is adsorbed by the dust removal adhesive portion 72 of the dust removal sheet 20, so the dust can be reliably removed as described below. The dust removal release sheet 90 is preferably made of paper coated with PP (polypropylene).
[0055] Next, as the drawer section 80 is pulled out of the lid opening 380, the dust collection sheet 20 and the release sheet 60 attached to the drawer section 80 are pulled almost simultaneously. At this time, the second hole 51b in the positioning sheet 50 fits into the columnar portion 390 in the lid section 360, and the columnar portion 390 fits into the hole 214b in the main body section 200. Furthermore, the protrusion 214a fits into the first hole 51a, and the locking portions 223b, 223b fit into the third hole portions 55a, 55a in the positioning sheet 50. Therefore, the dust collection sheet 20 attached to the positioning sheet 50 does not shift position with the display screen 500, and only the drawer section 80 can be pulled out. Furthermore, the dust collection sheet 20 temporarily attached to the display screen 500 begins to peel off from the display screen 500. As a result, dust adhering to the display screen 500 sticks to the dust removal sheet 20 and is removed.
[0056] At the same time, the release sheet 60 is peeled off from the protective sheet 40, exposing the adhesive portion 30. When the drawer portion 80 is further pulled out, the dust removal sheet 20 is completely peeled off from the display screen 500, and at the same time, the adhesive portion 30 of the protective sheet 40 is completely exposed.
[0057] Next, the recessed portion 395 in the lid portion 360 is pressed. The position of the recessed portion 395 in the lid portion 360 partially overlaps the position of the positioning opening 56. Therefore, by pressing the recessed portion 395, the protective sheet 40 exposed in the opening 56 can be pressed through the recessed portion 395 and the positioning opening 56. Therefore, when the recessed portion 395 is pressed, the protective sheet 40 pressed through the positioning opening 56 is attached to a portion of the display screen 500, and the attachment gradually expands from the pressed position until the entire protective sheet 40 is attached to the display screen 500. At this time, since the attachment gradually expands from the pressed position, the generation of air bubbles can be minimized. In other words, if the adhesive portion 30 is a silicone adsorption layer, the self-adsorption force gradually expands the attachment position from the pressed position, and the position spreads to cover the entire display screen 500. When the bottom surface portion 220 is inclined upward from the rear end portion 214 toward the front end portion 213 in a side view, the drawer portion 80 becomes easier to draw.
[0058] The second hole portion 51b in the positioning sheet 50 fits into the columnar portion 390 and further engages with the hole portion 214b, so that the protective sheet 40 can be attached to the display screen 500 without misaligning the protective sheet 40 and the mobile device 600 (see Figure 14).
[0059] Thereafter, the cover portion 360 is removed from the main body portion 200. Thereafter, the positioning sheet 50 is peeled off from the protective sheet 40, so that only the protective sheet 40 can be attached to the display screen 500.
[0060] In this way, the mobile device 600 can be inserted through the component opening 386 with the sheet 10 in place and the lid 360 already placed on the main body 200, thereby preventing dust from entering as much as possible. Furthermore, by pressing the recessed portion 395 when attaching the protective sheet 40, the generation of air bubbles can be minimized.
[0061] Moreover, since the protective sheet 40 is positioned in advance so as to be applied to the display screen 500, there is no need to correct the positional deviation of the protective sheet 40, so that even an inexperienced user can easily apply it.
[0062] Furthermore, the cover 360 is never removed from the main body 200 before the protective sheet 40 is attached to the display screen 500, thereby minimizing the intrusion of dust. Therefore, there is almost no possibility of dust adhering to the adhesive portion 30 or the dust-removing adhesive portion 72 of the dust-removing sheet 20, and the possibility of dust getting in between the display screen 500 and the protective sheet 40 can be reduced as much as possible.
