(Embodiment 1)
Hereinafter, a first exemplary embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view illustrating a cross section perpendicular to the longitudinal direction of the masker 11 according to the first embodiment. The masker 11 includes a tape 12 having a non-adhesive surface and an adhesive back surface, and a sheet 13 extending from a predetermined position of the tape 12.

  As elements constituting the masker 11, that is, the tape 12 and the sheet 13, there are a tape-shaped first component 14, a tape-shaped second component 15, and a sheet-shaped third component 16.

  The 1st structure part 14 is a tape-shaped member which has a non-adhesive surface and an adhesive back surface. The main body of the first component 14, that is, the base material, is made of, for example, a cloth having a strength that does not easily break. Although the surface of the first component 14 is non-adhesive, it is not peeled off because it needs to adhere strongly to the back surface of the second component 15. The back surface of the 1st component part 14 has weak adhesiveness compared with a general adhesive tape by the adhesive agent being apply | coated, for example. The reason why it is weaker than general adhesive tape is that it is necessary to easily peel off the masker 11 from the wall surface etc. after the painting work is finished, and the peeling mark remains on the wall surface or the surface of the wall surface is peeled off. This is to reduce the risk of accidents.

  The length of the first component 14 in the longitudinal direction is 12.5 meters, and the direction perpendicular to the longitudinal direction, that is, the length of the width is 2.5 centimeters.

  The second component 15 is a tape-like member having a non-adhesive surface and an adhesive back surface. The main body of the second component 15, that is, the base material is made of, for example, a cloth having a strength that does not easily break. The surface of the second component 15 is non-adhesive and is peeled over the entire surface. The back surface of the second component 15 has, for example, strong adhesiveness equal to or higher than that of a general adhesive tape by applying an adhesive. The reason why such strong adhesiveness is necessary is to prevent the second component 15 from being easily peeled off after being bonded to the first component 14 and the third component 16.

  The length of the second component 15 in the longitudinal direction is, for example, 12.5 meters, and the direction perpendicular to the longitudinal direction, that is, the width is, for example, 2.5 centimeters.

  The third component 16 is, for example, a synthetic resin film sheet. The length of the third component 16 in the longitudinal direction is, for example, 12.5 meters, and the direction perpendicular to the longitudinal direction, that is, the width is, for example, 1 meter.

  The masker 11 faces the front surface of the first component portion 14 and the back surface of the second component portion 15, and is parallel to the longitudinal direction in the middle of the width direction, that is, a position at a length of 50 percent from both ends in the width direction. It is generated by pressing the first component 14 and the second component 15 while sandwiching the third component 16 in a state where one end side extending in the longitudinal direction of the third component 16 is aligned with the straight line position.

  In this case, the tape 12 is configured by the first component 14 and the portion of the second component 15 whose back surface is adhered to the surface of the first component 14. And the sheet | seat 13 is comprised by the part which the back surface adheres to the one surface of the 3rd structure part 16 among the 2nd structure parts 15, and the 3rd structure part 16. FIG.

  In the masker 11 having such a configuration, on the surface of the tape 12, a straight line that is parallel to the longitudinal direction of the tape 12 and that is, for example, 50% long from both ends in the width direction of the tape 12. Then, the sheet 13 extends to the surface side of the tape 12.

  Compared with a normal masker, the masker 11 according to the first embodiment has the following characteristics. That is, when a force is applied from the outside to the sheet 13 in a state where the back surface of the tape 12 is attached to a wall surface or the like, the force that the sheet 13 applies to one point on the line connected to the tape 12 Since the component in the direction perpendicular to the wall surface is supported by the shear stress on both sides (in the connecting portion between the tape 12 and the sheet 13) in the direction perpendicular to the longitudinal direction of the tape 12 being affixed, the tape 12 is difficult to detach from the wall surface.

  That is, in a normal masker, since the sheet extends from one end in the width direction of the tape, the tape exists only on one side as viewed from the straight line formed by the connecting portion between the sheet and the tape. Therefore, when the sheet receives an external force, the external force is countered so that the sheet is not peeled off the wall surface only by the adhesive force of the tape located on one side of the straight line.

  On the other hand, in the masker 11, since the sheet 13 extends from the central portion in the width direction of the tape 12, the tape 12 exists on both sides as viewed from the straight line formed by the connecting portion between the sheet 13 and the tape 12. Therefore, when the sheet 13 receives an external force, the external force can be countered so that the sheet 13 is not peeled off from the wall surface by the adhesive force of the tape 12 positioned on both sides of the straight line.

  In this case, the sheet 13 has a strength that does not separate from the tape 12 at one point due to a component in a direction perpendicular to the wall surface of the force at one point on the line where the sheet 13 is connected to the tape 12. It is necessary that the sheet 13 and the tape 12 are connected. This is because even if the tape 12 does not detach from the wall surface due to an external force, if the sheet 13 is peeled off from the tape 12 due to the external force, there is no element or child.

  The masker 11 is conveniently in the state of the masker roll 17 as shown in FIG. 2, for example, when actually performing a curing operation or when being sold as a product. The masker roll 17 is formed by winding the masker 11 described above around the axis about a straight line perpendicular to the longitudinal direction of the masker 11.

  At this time, as shown in FIG. 2B, if the masker 11 is rolled up with the sheet 13 folded, the width in the direction perpendicular to the longitudinal direction of the product tape 12, that is, the so-called product width is set to an appropriate length. Can be adjusted. Further, the thickness of the folded sheet 13 is adjusted to be the same as the thickness of the tape 12 for the purpose of reducing the difference in thickness and hardness between the portion of the tape 12 and the portion of the sheet 13 in the masker roll 17. You can also

  In the first embodiment, as long as the third component 16 is sufficiently thin, the tape 12 has substantially the same thickness in the width direction. It is hard and is good as product. Further, since the surface of the second component 15 is peeled off, the back surface of the first component 14 and the surface of the second component 15 stick to each other so that it is difficult to pull out the masker 11 from the masker roll 17. Hateful.

(Modification of Embodiment 1)
The first embodiment can be variously modified within the scope of the technical idea of the present invention. Hereinafter, examples of such modifications will be described.

(One Modification of Embodiment 1)
FIG. 3 is a view showing a modification of the first embodiment. In the following, the description will be focused on the points in which this modification is different from the above-described first embodiment.

  In this modification, the surface of the first component 14 has adhesiveness like the back surface of the second component 15. The third component 16 is parallel to one end parallel to the longitudinal direction and is half the width of the first component 14 (the length in the direction perpendicular to the longitudinal direction) from the end. It is bent with a straight line that is only a distance away. Hereinafter, of the two regions obtained by dividing the third component 16 by creases, the region 161 having the shorter length from the crease to the edge is referred to as region 161, and the region having the longer length as region 162.

  The end of the region 161 that is not the fold side coincides with one end of the first component 14, and the fold line that separates the region 161 and the region 162 coincides with the center line in the width direction of the first component 14. The third component 16 is arranged on the first component 14 so that the back surface of the region 161 is adhered to the surface of the first component 14 at the position.

  In addition, the spacer 30 is disposed on the surface of the first component 14 so as to cover all portions of the surface of the first component 14 that are not covered by the region 161 of the third component 16. The spacer 30 is, for example, a film sheet made of the same material as that of the third component 16, and has a thickness in which two third components 16 are stacked, that is, a thickness in which the region 161 and the region 162 of the third component 16 are stacked. It has.

  This spacer 30 avoids the disadvantage that a difference in diameter occurs between the portion where the tape 12 is wound and the portion where the sheet 13 is wound when the masker roll 17 shown in FIG. It is used for. Therefore, when the thickness of the third component 16 is sufficiently thin, the spacer 30 may not be used.

  As described above, with the third component 16 and, if necessary, the spacer 30 disposed on the surface of the first component 14, the back surface of the second component 15 is the region 162 of the first component 14. It is bonded to the surface and the surface of the spacer 30. As a result, as shown in FIG. 3A, the masker 11 including the tape 12 and the sheet 13 is formed.

  The tape 12 has a first component 14 and a portion of the second component 15 where the back surface is adhered to the surface of the spacer 30 (when the spacer 30 is used) or the back surface is adhered to the first component 14. Part (when the spacer 30 is not used), the region 161 of the third component, and the spacer 30 (when the spacer 30 is used).

  In addition, the sheet 13 includes a portion of the second component 15 whose back surface is adhered to the surface of the region 162 of the third component 16 and a region 162 of the third component 16.

  Compared with the masker 11 according to the first embodiment described above, the masker 11 created as described above can easily increase the strength against the force applied to the seat 13 from the outside during use. Because, first, both the front surface of the first component portion 14 and the back surface of the second component portion 15 have adhesiveness, it is easy to ensure strong adhesion in a region where the third component portion 16 is not sandwiched. Because there is. Further, the third component 16 is fixed to each of the first component 14 and the second component 15, and the region 161 of the third component 16 fixed to the first component 14 is external to the sheet 13. This is because the third component 16 generates a force that resists the separation of the first component 14 and the second component 15 at the fold portion because it extends in a direction that forms an acute angle with respect to the direction of the force applied from the first.

(Other variations of Embodiment 1)
Hereinafter, modifications other than the above-described modification will be described.

  The sheet 13 is stretched from a straight line having a length of 50 percent in the width direction of the tape 12. However, as long as the purpose of preventing the tape 12 from being peeled off from the wall surface by an external force can be achieved, the sheet 13 is formed. It is not necessary that the stretched position of the tape is a position having a length of 50 percent in the width direction of the tape 12. That is, the sheet 13 extends from a straight line parallel to the longitudinal direction of the tape 12 on a predetermined region inside the surface of the tape 12 which is not one of the two ends parallel to the longitudinal direction of the tape 12 to the surface side of the tape. What is necessary is just to extend | stretch.

  However, empirically, the predetermined area described above is an area that does not include an area having a length of 25 percent in the direction perpendicular to the longitudinal direction of the tape 12 from each of the two end sides parallel to the longitudinal direction of the tape 12. In many cases, the effects of the present invention can be sufficiently obtained.

  The first component 14 and the second component 15 are made of cloth, but may be made of other materials such as paper or synthetic resin as long as they are not torn by externally generated external force.

  The third component 16 is a synthetic resin film sheet, but may be made of other materials such as paper or cloth as long as it is not broken by an external force generated normally.

  Further, as the adhesive applied to the back surface of the first component 14 and the surface of the second component, a natural rubber type, a synthetic rubber type, an acrylic type, and other various types are appropriately employed depending on each purpose. That's fine.

  Further, the length in the longitudinal direction of the first component 14 and the second component 15 is 12.5 meters, and the length in the direction perpendicular to the longitudinal direction is 2.5 centimeters. Is not limited by these values.

  The length of the third component 16 in the longitudinal direction is 12.5 meters, and the length in the direction perpendicular to the longitudinal direction is 1 meter. However, the present invention is limited by these numerical values. is not.

  In addition, as shown in FIG. 1C, the first component 14 and the second component 15 are changed in size so that the first component 14 has a narrow area in the width direction on the surface of the first component 14. You may affix the 2nd structure part 15 in the state which pinched | interposed the one edge side of the 3 structure part 16. FIG. In this case, there is an advantage that the required amount of the second component 15 can be reduced. However, in this case, in order to reduce the step in the thickness direction of the tape 12, it is desirable that the thickness of the second component 15 is sufficiently thin.

  Moreover, although the peeling process was given to the whole surface of the 2nd structure part 15, this invention is not limited to it. That is, as long as it is not difficult when pulling out the masker 11 from the masker roll 17, a peeling process may be performed only on a part of the surface of the second component 15, or the surface of the second component 15 may be peeled at all. Processing may not be performed.

(Embodiment 2)
Hereinafter, Embodiment 2 which is a specific example of the present invention will be described with reference to the drawings. In addition, about the same part as Embodiment 1, description is abbreviate | omitted partially.

  FIG. 4 is a cross-sectional view illustrating a cross section perpendicular to the longitudinal direction of the masker 11 according to the second embodiment. The masker 11 includes a tape 12 having a non-adhesive surface and an adhesive back surface and a sheet 13 extending from a predetermined position of the tape 12 as in the first embodiment.

  As elements constituting the masker 11, that is, the tape 12 and the sheet 13, there are a tape-like first component 18 and a sheet-like second component 19.

  The first component 18 is a tape-like member having an adhesive surface and an adhesive back surface.

  The second component 19 is a synthetic resin film sheet. The second component 19 is parallel to one end parallel to the longitudinal direction and is separated from the end by the same length as the width of the first component 18 (the length in the direction perpendicular to the longitudinal direction). In a state where the straight line is folded as a crease, the fold of the second component 19 in the entire length (region S in FIG. 4A) of, for example, 50% of the width of the first component 18 from the fold. The portions that are folded together by overlapping are bonded together by heat treatment.

  In addition, in the part of the same length as the width | variety of the 1st structure part 18 of the other edge side which opposes one edge side from the above-mentioned fold among the 2nd structure part 19, the whole surface of the side which is not adhere | attached by heat processing A peeling process is applied to (region T in FIG. 4A). As will be described later, this peeling process has an advantage that the masker 11 can be easily pulled out from the masker roll 17.

  The entire surface of the first component 18 is affixed to the entire surface of the second component 19 that is not bonded by heat treatment at a portion between one end side and the crease. In this way, the masker 11 according to the second embodiment is generated.

  In the masker 11, the first component 18, the portion between one end of the second component 19 and the crease, the one end of the second component 19 and the crease by adhesion by heat treatment, The tape 12 is constituted by a portion bonded to the portion between the two. And from the other end side, which is the end side opposite to one end side of the second component part 19 of the second component part 19, to the outer edge on the other edge side of the part bonded to each other by the heat treatment bonding The sheet 13 is constituted by the portions.

  In the masker 11 having such a configuration, the sheet 13 extends from the surface of the tape 12 to the surface side of the tape 12 from a straight line at a position of 50 percent from both ends in the width direction of the tape 12. Therefore, the masker 11 according to the second embodiment described above has a characteristic that the tape 12 is less likely to be detached from the wall surface than the normal masker for the same reason as the masker 11 according to the first embodiment.

  Also in the second embodiment, as in the first embodiment, the tape 12 has substantially the same thickness in the width direction. Therefore, when the masker roll 17 is formed, the unevenness is hardly formed, and the product is good.

  Moreover, since the predetermined area | region of the surface of the 2nd component part 19 is peel-processed, when pulling out the masker 11 from the masker roll 17, the back surface of the 1st component part 18 and the surface of the 2nd component part 19 are hard to peel off. The problem is difficult to occur.

  In addition, if the above-mentioned advantage can be maintained, it is not necessary to perform peeling processing on the entire surface of the portion of the masker roll 17 where the second component 19 and the first component 18 overlap. That is, in the masker roll 17, the peeling process may not be performed in a part of or the entire region where the second component 19 overlaps the first component 18.

  In addition, in the state where the second component 19 is folded with a straight line that is parallel to one end side parallel to the longitudinal direction and separated from the end by the same length as the width of the first component 18 as a crease, From the fold line, the entire length of 50% of the width of the first component 18, that is, the folded portion of the second component 19 in the entire region S in FIG. 4A is bonded by heat treatment. However, it may be bonded only in a partial region inside the region S.

  Further, the portion of the second component 19 that is folded and bonded, that is, the length in the width direction of the region S in FIG. 4A is 50% of the length of the first component 18 in the width direction. However, the present invention is not limited to this, and any length may be adopted as long as the length of the region S in the width direction is shorter than the length of the first component 18 in the width direction. However, as a result of experience, the portions of the second component 19 that overlap each other so that the sheet 13 extends from a straight line in the region excluding the region having a length of 25% from each of both ends in the width direction of the tape 12 are mutually connected. In many cases, the effect of the present invention is sufficiently obtained.

  Further, the bonding between the folded portions of the second component 19 is not limited to heat treatment, and the bonding may be performed with an adhesive, a double-sided tape, or the like.

  In addition, as a method of the peeling process with respect to the 2nd structure part 19, the method of apply | coating peeling agents, such as a silicone resin, may be employ | adopted, for example, and the back surface has strong adhesiveness and the peeling process was given to the surface A method of attaching a tape-shaped material to the surface of the second component 19 may be employed.

(One Modification of Embodiment 2)
In Embodiment 2 mentioned above, the part which comprises the sheet | seat 13 among the 2nd structure part 19 is between the edge and one crease | fold of the 2nd structure part 19 in the area | region S among the 2nd structure parts 19. FIG. Stretching in the same direction as the stretching direction of the part bonded to the part. That is, there is no fold in the second component 19 in the region T in FIG.

  When this is deformed and the boundary line between the part of the second component 19 that is adhered and the part that is not adhered is a crease, the second component 19 is viewed in a direction parallel to the longitudinal direction. The part which comprises the sheet | seat 13 among the 2nd structure part 19 is bent so that it may become a type | mold, and the part between one edge and the crease | fold of the 2nd structure part 19 in the area | region S among the 2nd structure part 19 You may make it extend | stretch in the direction opposite to the extending | stretching direction of the part currently adhere | attached.

  FIG. 5A is a diagram showing such a modification. In this modification, it is desirable that the masker 11 can be easily pulled out from the masker roll 17 if the area U shown in FIG. 5A is subjected to the peeling process instead of the area T shown in FIG.

  Moreover, you may employ | adopt the structure which affixes the 3rd structure part 31 which is a tape-shaped member which has a non-adhesive surface and an adhesive back surface in the area | region U. FIG. FIG. 5B is a diagram showing such a modification.

  Furthermore, it is desirable that the surface of the third component 31 be subjected to a peeling process because the masker 11 can be easily pulled out from the masker roll 17.

  According to the masker 11 shown in FIG. 5B, when a force is applied to the sheet 13 from the outside, the third component 31 separates the parts of the second component 19 that are bonded to each other, or the second Since the force which resists peeling from the 1st structure part 18 of the 2 structure part 19 is produced, the intensity | strength of the masker 11 can be raised easily.

  Furthermore, when the configuration in which the third component 31 is sandwiched between the first component 18 and the second component 19 is adopted, the second component 19 is not necessarily the first component 18 as shown in FIG. There is no need to cover the entire surface of the. That is, a part or all of the region V in FIG. 5C among the surface of the first component 18 may directly adhere to the third component 31 without sandwiching the second component 19.

  Further, when adopting a configuration in which the third component part 31 is sandwiched between the first component part 18 and the second component part 19, adhesion by heat treatment or the like of the parts of the second component part 19 that are folded over each other, that is, FIG. Bonding in the region S in 5 (a) may not be performed. This is because the folded second component 19 in the region S is not separated by the third component 31.
