Description

  The present invention relates to an improvement of a protective film attaching member attached to a monitor screen, particularly a liquid crystal monitor screen for car navigation.

  The monitor screen, especially the LCD monitor screen, becomes dirty due to fingerprints and dirt attached to it when used. Therefore, generally, it is used in the state where the protective film was stuck. The protective film sticking member in a state before use is usually a three-layer structure in which a cover film is attached to the front surface of the protective film and a release film is attached to the rear surface. This protective film is used on the entire monitor screen for PCs, games, TVs, mobile phones, smartphones, vending machines, medical devices, and ticket machines. The shape is formed according to the monitor screen.

  In order to attach the protective film 21 to the monitor screen 11, as shown in FIG. 8, first, a release film (not shown) is peeled off from the back surface of the protective film 21, and an adhesive layer 21 a on the back surface of the protective film 21. Next, the upper end of the protective film 21 is adhered to the end of the monitor screen 11 and adhered, and the protective film 21 is moved from the adhesive end of the surface of the monitor screen 11 toward the other end while pulling and holding the finger. Paste. Finally, the cover film 23 is peeled off from the surface of the attached protective film 21 to finish the operation. At this time, it is necessary to prevent bubbles K from entering between the adhesive layer 21 a and the monitor screen 11. Such protective films include the following (Patent Document 1).

JP-A-7-313949 (FIG. 2)

  However, since the entire protective film sticking member is cut to the size of the monitor screen 11, when the release film is peeled off when sticking the protective film sticking member, as described above, the adhesive layer on the back surface of the protective film 21 When the protective film 21 with the cover film 23 attached to the surface thereof is picked during the sticking operation, the adhesive layer 21a comes into contact with and sticks to the picked index finger.

  In this state, as described above, the upper end of the protective film 21 is adhered so as to coincide with the upper end of the monitor screen 11, and the protective film 21 is pasted from the adhesive end to the lower end of the surface of the monitor screen 11 while pulling as it is and holding the finger. When it is going to be attached, the adhesive layer 21a exposed at the lower end of the protective film 21 is inadvertently adhered to the monitor screen 11 or the adhesive layer 21a adhered to the finger is difficult to separate when the finger is changed. Bubbles K may be loosened or slackened, or air bubbles K may enter between the protective film 21 and the monitor screen 11 which are inadvertently adhered, making it difficult to apply them cleanly.

  Further, since the release film is formed in the same size as the protective film 21, there is a problem that it is difficult to remove the release film from the protective film 21. Of course, if the release film is slightly larger than the protective film 21, it is possible to eliminate the difficulty at the time of peeling, but in this case, for example, the monitor screen 11 is larger than the surrounding frame. In the case where it is located in a place where it is recessed by one step, there is also a problem that this large release film becomes an obstacle and it is impossible to align the protective film 21 on the monitor screen 11.

  The present invention allows anyone to easily and beautifully attach a protective film that is difficult to stick on the monitor screen even when the monitor screen is located in a place that is one step lower than the surrounding frame. It is in providing the protective film sticking member which can be performed.

The protective film sticking member A of claim 1 has a structure in which “the cover film 3 is stuck on the front surface of the protective film 1 and the release film 2 is stuck on the adhesive layer 1 a on the back surface of the protective film 1. ,
The release film 2 is composed of a main body portion 2a having the same shape as that of the protective film 1 and ear portions 5 projecting from both sides 2a2 of the main body portion 2a to the outside of the protective film 1. To do.

  The protective film sticking member A of claim 2 is "the ear part 5 of the release film 2 of claim 1 is on the outside of the protective film 1 from both sides 2a2 of the main body portion 2a to one side 2a1 between the sides 2a2. It is characterized by “overhanging”.

  The protective film sticking member A according to claim 3 is "the ear part 5 of the release film 2 according to claim 1 or 2 is provided with a fold line 5b that is parallel to or coincides with one side 2a1 of the main body part 2a". It is characterized by that.

  According to this, the ear | edge part 5 is pinched with a finger | toe, the edge part 2x of the release film 2 is peeled from the edge part 1x of the protective film 1, this edge part 1x and the adhesive layer 1a of the vicinity are exposed, a mold release The end portion 2x of the film 2 is folded back to the back side, and the folded ear portion 5 and the side portion of the protective film 1 with the cover film 3 attached to the surface are picked with fingers, and the end of the protective film 1 in this state In the state where the adhesive layer 1a of the part 1x is adhered along the end of the monitor screen 11 and the folded ear part 5 and the protective film 1 are gripped or only the folded ear part 5 is gripped. The finger is moved while pulling lightly on both sides, and the adhesive layer 1a is attached to the entire surface of the monitor screen 11 from the top to the bottom. As a result, the protective film 1 can be neatly applied to the entire surface of the monitor screen 11 without the adhesive layer 1a being attached to the finger or undesirably attached to the monitor screen 11. Here, in the part (main part 2a) where the release film 2 of the protective film sticking member A has not yet peeled, the protective film 1 and the release film 2 have the same shape. The pasting operation can be performed while aligning the monitor screen 11 that is recessed by one step.

  In particular, when the ear portion 5 is bent along the folding line 5a, a gap S is generated between the adhesive layer 1a of the protective film 1 and the monitor screen 11 when the protective film 1 is attached to the protective film 1. And the other end 1y side of the protective film 1 is flipped up by the elastic force F of the fold line 5b portion of the ear 5 and is separated from the monitor screen 11. In this state, if the release part 2 is slowly moved to the other end 1y side of the protective film 1 by grasping the ear part 5 while applying a light tension in the width direction, it can be neatly attached only by this.

The disassembled perspective view of the protective film member of this invention. (a) is a perspective view of the first embodiment of the protective film member of the present invention, (b) is a partial perspective view of the bent state of the ear, (c) is a perspective view of the second embodiment, (d) is The partial perspective view which shows the state which bent the ear | edge part of 2nd Example. The perspective view at the time of sticking of 1st Example. The perspective view of the state which has pushed out air bubbles to the circumference with a finger at the time of pasting of the 1st example. The perspective view of the state which is extruding the bubble to the circumference using a spatula at the time of sticking of 1st Example. The perspective view of the state which has peeled the cover film at the time of sticking of 1st Example. The perspective view which shows the sticking state of the protective film of this invention. The perspective view which shows the pasting state of the conventional protective film.

  Hereinafter, although detailed content is demonstrated using an Example, this invention is not limited to a following example. Although the protective film sticking member A of this invention is common to any Example, the cover film 3 thinly colored in the front surface of the transparent protective film 1, and the adhesion | attachment provided in the back surface whole surface of the protective film 1 It has a three-layer structure in which a transparent release film 2 is attached to the layer 1a (in addition, a functional layer for anti-glare and a functional layer that has been devised to make it easy to see on the front surface of the protective film 1) In some cases, these functional layers are included in the protective film 1). The sizes of the main body portion 2 a of the protective film 1, the cover film 3 and the release film 2 are formed in accordance with the monitor screen 11. For the protective film 1, for example, a resin sheet such as PET is used. A tape 4 serving as a handle for peeling is attached to the lower right corner of the cover film 3 in the figure.

  The monitor screen 11 to which the protective film 1 of the present invention is attached is usually provided in a place recessed by one step from the frame 12 of the display device 10 like a liquid crystal monitor screen for car navigation, and the four rounds thereof are the frame 12. It is surrounded and it is difficult to cleanly attach the protective film 1.

  In the first embodiment of the present invention, as shown in FIGS. 1, 2 (a) and 2 (b), the ear portion 5 of the release film 2 is located on both sides 2a2 adjacent to the side 2a1 from one side 2a1 of the main body portion 2a. Is projected outside the main body portion 2a of the protective film 1. The main body portion 2 a has the same shape as the protective film 1.

  The overhanging width to the outside of both sides of the ear part 5 is such that the side overhanging part 5a can be picked with a finger, and is about 4 mm to 10 mm. About 5 mm to 7 mm is preferable. And the protruding part 5c of the ear | edge part 5 to the outer side (upward) of the one side 2a1 of the main-body part 2a can be bent along the one side 2a1 of the main-body part 2a. This foldable portion is indicated by a fold line 5b (FIG. 2 (a)). This fold line 5b may be easily bent by making a perforation or the like, or may be bent along the one side 2a1 of the main body portion 2a as it is. The protruding width of the overhanging portion 5c on the side 2a1 side is set to a width that is easy to bend and can hold the bent state when bent, for example, about 7 to 12 mm. 8 mm to 10 mm is preferable. In addition, the overhang | projection part 5c is provided with the product number corner 6 of the protective film sticking member A of this invention.

  Although not shown in the figure, for example, a liquid crystal cleaner spray is sprayed on the monitor screen 11 to wipe off dirt and fingerprints with a clean cloth. The dust and dust at the four corners are blown away with dust spray to clean the entire surface of the monitor screen 11.

  Next, the ear | edge part 5 of the release film 2 is pinched with a finger | toe, and the overhang | projection part 5c of the release film 2 is folded back to the back side by the fold line 5b along the edge 1x (upper end) side of the protective film 1 (FIG. 2). (b)). In particular, if the protective film 1 is bent along the fold line 5b, a gap S is generated between the adhesive layer 1a of the protective film 1 and the monitor screen 11 as shown in FIG. Then, the other end 1y side of the protective film 1 is flipped up by the fact that the other part of the adhesive layer 1a does not undesirably adhere to the monitor screen 11 and the elastic force F of the fold line 5b part of the ear part 5. As a result of the part being separated from the monitor screen 11, it becomes easier to paste.

  Then, the release film 2 is peeled off from the end portion 1x of the protective film 1 to expose the end portion 1x and the adhesive layer 1a in the vicinity thereof, and the folded ear portion 5 and the cover film 3 are attached to the surface. The film 1 is picked with a finger, and in this state, the adhesive layer 1a of the end 1x of the protective film 1 is adhered along the end of the monitor screen 11 (FIG. 3). Since the pinched fingers are in contact with the cover film 3 and the ear part 5 and do not come into contact with the adhesive layer 5a, both sides of the folded finger part 5 and the protective film 1 are gripped or only the ear part 5 is gripped. The finger is moved downward while pulling lightly, and the release film 2 is peeled off and pasted from top to bottom.

  Here, since the protective film 1 and the release film 2 have the same shape, the part (main body part 2a) of the protective film sticking member A where the release film 2 has not yet peeled is directed to the monitor screen 11. However, it does not interfere with the surrounding frame 12 that is raised one step. In other words, the attaching operation can be performed while aligning the main body portion 2a of the protective film attaching member A to the monitor screen 11 that is recessed by one step from the frame 12.

  When the protective film 1 is slid to the other end 1y (lower end), the adhesive layer 1a is uniformly adhered to the entire surface of the monitor screen 11, and the protective film 1 can be adhered to the entire surface of the monitor screen 11 neatly.

  In this state, if the bubble K is slightly caught between the protective film 1 and the monitor screen 11, for example, the finger K is slid from the center of the protective film 1 to the peripheral portion to protect the bubble K. Extrude to film 1 (FIG. 4). When the extrusion of the bubbles K is finished, the spatula 8 is slid while pressing from the top of the cover film 3 onto the surface of the protective film 1 in order to uniformly adhere the adhesive layer 5a to the monitor screen 11 (FIG. 5). Finally, the tape 4 of the cover film 3 adhered to the surface of the protective film 1 is pulled and peeled off (FIG. 6).

  In the second embodiment, as shown in FIG. 2 (c), the release film 2 is formed only by extending the ears 5 of the release film 2 from both sides of the protective film 1. It is cut where it coincides with one side 1x. The sticking method is the same as in the first embodiment. However, in this case, since the shape of the ear part 5 is different from that of the first embodiment, in this case, as shown in FIG. One of these parts will be folded back.
