Description

  The present invention relates to an adhesive roll used for indoor cleaning.

  An adhesive cleaner equipped with an adhesive roll is widely known as an indoor floor cleaning tool. The pressure-sensitive adhesive roller is formed by winding a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer on one surface of a base sheet, around a cylindrical core with the pressure-sensitive adhesive layer as the front side.

  In general, in such an adhesive roll, a large number of cuts (slits) are formed in a direction orthogonal to the winding direction of the adhesive sheet. Thus, since the cut | interruption is formed in the adhesive sheet, a part of adhesive sheet can be peeled from an adhesive roll, and it can cut | disconnect and discard at the part of a cut | interruption. Thereby, the new adhesive surface of the adhesive roll is exposed and can be used again for cleaning.

  For example, an adhesive roll in which a perforation is provided straight from one side edge portion to another side edge portion is known (see Patent Document 1). Moreover, the adhesive roll which provided the cut | interruption for cut lines in a step is known (refer patent document 2). Furthermore, there is known an adhesive roll provided with cut lines for cut lines in a stepwise and oblique direction (see Patent Document 3).

  However, in the pressure-sensitive adhesive rolls described in Patent Documents 1 to 3, when a long hair is wound around the surface of the pressure-sensitive adhesive roll, the hair may prevent the pressure-sensitive adhesive sheet from being separated.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide an adhesive roll capable of easily separating an adhesive sheet. More specifically, adhesion of long hair or the like to the sheet portion related to separation of the adhesive roll is reduced, and even if long hair adheres to the sheet portion related to separation of the adhesive roll, the adhesive sheet Easy separation.

  The pressure-sensitive adhesive roll of the present invention comprises a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer on one surface of a substrate sheet, and a core for winding the pressure-sensitive adhesive sheet, and the pressure-sensitive adhesive layer is turned to the front side, and the pressure-sensitive adhesive sheet Is a pressure-sensitive adhesive roll wound around the core, and the pressure-sensitive adhesive roll has a plurality of long holes extending from the surface side of the pressure-sensitive adhesive roll to the core. It arrange | positions in parallel without being contacted, and is arrange | positioned at step shape so that the area | region of an edge part may overlap in the winding direction of the said adhesive sheet.

  In the pressure-sensitive adhesive roll of the present invention, the plurality of long holes are arranged in a direction orthogonal to the winding direction of the pressure-sensitive adhesive sheet, or the plurality of long holes are in the winding direction of the pressure-sensitive adhesive sheet. It is preferable that they are arranged in an oblique direction.

  In the pressure-sensitive adhesive roll of the present invention, a wedge-shaped notch extending from the surface side of the pressure-sensitive adhesive roll to the core is formed on one side edge, and the notch and the plurality of long holes are in contact with each other. It is preferable that the end regions are arranged stepwise so that the end regions overlap partially in the winding direction of the pressure-sensitive adhesive sheet.

  In the pressure-sensitive adhesive roll of the present invention, slits extending from the surface side of the pressure-sensitive adhesive roll to the core are formed on the other side edge, and the plurality of long holes and the slits are arranged in parallel without contacting each other. And it is preferable to arrange | position in the step shape so that the area | region of an edge part may overlap in the winding direction of the said adhesive sheet.

  In the pressure-sensitive adhesive roll of the present invention, the lottery result is preferably displayed on the surface of the core.

  According to the present invention, the adhesion of long hair or the like to the sheet portion related to the separation of the adhesive roll is reduced, and even if the long hair adheres to the sheet portion related to the separation of the adhesive roll, the adhesive The sheet can be easily separated.

It is a figure which shows the use condition of the adhesive roll of this invention. It is a perspective view which shows typically one Embodiment of the adhesive roll of FIG. It is a perspective view which shows the winding core of FIG. It is a perspective view which shows typically other embodiment of the adhesive roll of FIG.

  Hereinafter, the pressure-sensitive adhesive roll of the present invention will be described with reference to the drawings. However, the same elements are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 1, the pressure-sensitive adhesive roll 1 of the present invention is typically mounted on a roller provided at the tip of a bowl-shaped handle, and is mainly used for indoor floor cleaning.

  As shown in FIGS. 1 and 2, the adhesive roll 1 includes an adhesive sheet 2 and a core 4. The pressure-sensitive adhesive sheet 2 is wound around the core 4 so that the pressure-sensitive adhesive layer is on the front side.

  The winding core 4 is a core material for winding the adhesive sheet 2. The shape is not particularly limited. For example, the core 4 is formed in a cylindrical shape. The material is not particularly limited. For example, any material having sufficient strength for winding an adhesive sheet such as cardboard or plastic may be used.

  As shown in FIG. 3, the lottery result is preferably displayed on the surface of the core 4. With such a configuration, a lottery result appears when the pressure-sensitive adhesive sheet 2 is used up, and the playability of using the pressure-sensitive adhesive roll 1 can be improved. The display method of the lottery result is not particularly limited. For example, a method of printing characters such as “around” and “out of” on the surface of the core 4 can be exemplified.

  The adhesive sheet 2 is an adhesive sheet having an adhesive layer on one surface of the base sheet. What is necessary is just to set suitably about the width | variety of a base material sheet according to the objective of an adhesion roll, and it does not specifically limit. For example, what is necessary is just to comprise from 9 cm to 30 cm.

  The material of the base sheet is not particularly limited. For example, a flexible material such as paper or a plastic sheet can be suitably used. In the pressure-sensitive adhesive roll 1 of the present invention, the pressure-sensitive adhesive layer is formed on one surface of the base sheet, and the pressure-sensitive adhesive layer is not formed on the other surface. And it is preferable that the release agent layer is formed in the surface in which the adhesive layer of a base material sheet is not formed. For example, it becomes easy to peel the adhesive sheet 2 from the adhesive roll 1 by forming a release agent layer made of a silicone-based release agent.

  As shown in FIGS. 1 and 2, the adhesive roll 1 is formed with a plurality of, here, three elongated holes 6 having the same shape and the same size, from the surface side of the adhesive roll 1 to the core 4. In addition, if the number of the long holes 6 is plural (that is, 2 or more), it is not particularly limited to three. “From the surface side of the pressure-sensitive adhesive roll to the core” means that a long hole formed in the pressure-sensitive adhesive sheet 2 wound in a roll shape penetrates to the core. The plurality of long holes 6 are arranged in parallel without contacting each other. In other words, it means that the plurality of long holes 6 and their extension lines are arranged in parallel and do not cross each other.

  The long hole 6 is a hole having a certain width. The length of the long hole 6 is determined so as to be within the width of the pressure-sensitive adhesive sheet 2 (that is, not to reach the side edge of the pressure-sensitive adhesive sheet 2). If the long hole 6 is formed so as to reach the side edge of the pressure-sensitive adhesive sheet 2, the pressure-sensitive adhesive sheet 2 may be unintentionally peeled from the side edge side of the pressure-sensitive adhesive roll 1, which is not preferable. Typically, the long hole 6 is formed to have a width of 5 mm. However, the width of the long hole is not particularly limited. It suffices if a gap that allows the hair to float is formed. For example, the width of the long hole 6 is preferably 2 mm or more and 8 mm or less.

  The long holes 6 are arranged at intervals of 10 mm in width. However, the interval between the long holes is not particularly limited. It suffices if the long holes 6 are arranged close enough to easily separate the adhesive sheet 2. For example, it is preferably 5 mm or more and 15 mm or less.

  And the some long hole 6 is arrange | positioned at step shape so that the area | region of an edge part may overlap in the winding direction D of the adhesive sheet 2. As shown in FIG. “Stair-like” means that the plurality of long holes 6 are arranged in steps and the plurality of long holes 6 gradually step from one side edge to the other side edge of the pressure-sensitive adhesive sheet 2. It means the shape that lowers.

  As shown by the one-dot chain line in FIG. 2, in the adhesive roll 1, the long holes 6 are arranged so as to overlap each other in the winding direction D of the adhesive sheet 2 by 10 mm in width. However, the overlapping width between the long holes is not particularly limited. It suffices that the long holes are arranged so as to be easily separated from each other. For example, it is preferably 5 mm or more and 15 mm or less.

  As another embodiment of the pressure-sensitive adhesive roll of the present invention, as in the pressure-sensitive adhesive roll 100 shown in FIG. 4, the plurality of long holes 106 are perpendicular to the winding direction D of the pressure-sensitive adhesive sheet 102 (that is, the width of the pressure-sensitive adhesive sheet 102). (Parallel to the direction) can be mentioned. However, like the adhesive roll 1 shown in FIGS. 1 and 2, the plurality of long holes 6 are preferably arranged in an oblique direction with respect to the winding direction D of the adhesive sheet 2. By setting it as such a structure, it becomes possible to cut away an adhesive sheet easily with little force.

  The inclination angle of the long hole 6 with respect to the winding direction D of the adhesive sheet 2 is set to 10 °. However, the inclination angle with respect to the winding direction of the adhesive sheet is not particularly limited. It only needs to be inclined with respect to the winding direction. For example, the angle is preferably 5 ° or more and 20 ° or less.

  In the adhesive roll 1, a wedge-shaped notch 8 extending from the surface side of the adhesive roll 1 to the core 4 is formed at one side edge of the adhesive roll 1. By forming the notch 8, it becomes easy to understand the starting point when the adhesive sheet 2 is peeled off.

  The “wedge shape” means a V shape. The notch 8 has a side closer to the long hole 6 (an end side of the pressure-sensitive adhesive sheet 2) located in a direction perpendicular to the winding direction D of the pressure-sensitive adhesive sheet 2, and a side farther from the long hole 6 of the pressure-sensitive adhesive sheet 2 ( The wrapping side of the pressure-sensitive adhesive sheet 2 is formed in a V shape located in a direction inclined from the winding direction D. The shape of the notch 8 can indicate to the user the direction in which the pressure-sensitive adhesive sheet 2 is peeled off.

  In the pressure-sensitive adhesive roll 1, the cutout 8 is formed so as to bite 20 mm from the side edge of the pressure-sensitive adhesive sheet 2 to the center in the width direction. However, the size of the notch 8 is not particularly limited. A size that is easy to separate the pressure-sensitive adhesive sheet 2 and that makes it easy to understand the starting point when the pressure-sensitive adhesive sheet 2 is peeled off is sufficient. For example, it is preferably 15 mm or more and 25 mm or less.

  And the notch part 8 and the some long hole 6 are arrange | positioned, without mutually contacting. In the pressure-sensitive adhesive roll 1, the cutout portion 8 is disposed on the winding side of the pressure-sensitive adhesive sheet 2, and the plurality of long holes 6 are disposed on the end portion side of the pressure-sensitive adhesive sheet 2. If it is such a form, the adhesive sheet 2 can be cut off by breaking the adhesive sheet 2 in the direction of the plurality of long holes 6 from the notch 8.

  Further, the notch 8 and the plurality of long holes 6 are arranged in a stepped manner so that the end regions partially overlap in the winding direction D of the adhesive sheet 2. In the adhesive roll 1, the elongated hole 6 and the notch 8 at the right end in the figure are arranged in a stepped manner so as to partially overlap. The meaning of “staircase” is synonymous with the case of the long holes 6.

  In the adhesive roll 1, the long hole 6 and the notch 8 are arranged so as to overlap each other by 5 mm in the winding direction D of the adhesive sheet 2. However, the overlapping width of the long hole and the notch is not particularly limited. It is sufficient that the long hole and the cutout portion are arranged so as to be easily separated from the adhesive sheet. For example, it is preferably 3 mm or more and 7 mm or less.

  In the pressure-sensitive adhesive roll 1, a slit 10 extending from the surface side of the pressure-sensitive adhesive roll 1 to the core 4 is formed on the other side edge (the side edge where the notch 8 is not formed). Yes. By forming the slit 10, the adhesive sheet 2 can be easily separated while preventing the adhesive sheet 2 from being unintentionally peeled off.

  “Slit” means a linear cut. It differs from the “long hole” in the present invention in that it has substantially no width.

  In the adhesive roll 1, the slit 10 is formed so as to bite 20 mm from the side edge of the adhesive sheet 2 to the center in the width direction. However, the size of the slit 10 is not particularly limited. A size that can easily separate the pressure-sensitive adhesive sheet 2 is sufficient. For example, it is preferably 15 mm or more and 25 mm or less.

  And the some long hole 6 and the slit 10 are arrange | positioned in parallel, without mutually contacting. In other words, it means that the plurality of long holes 6 and their extension lines, the slit 10 and their extension lines are arranged in parallel and do not cross each other.

  In the pressure-sensitive adhesive roll 1, the plurality of long holes 6 are disposed on the winding side of the pressure-sensitive adhesive sheet 2, and the slit 10 is disposed on the end side of the pressure-sensitive adhesive sheet 2. If it is such a form, the adhesive sheet 2 can be cut off by breaking the adhesive sheet 2 in the direction of the slit 10 from the direction of the plurality of long holes 6.

  Further, the notch 8 and the plurality of long holes 6 are arranged in a stepped manner so that the end regions partially overlap in the winding direction D of the adhesive sheet 2. In the adhesive roll 1, the elongated hole 6 and the notch 8 at the right end in the figure are arranged in a stepped manner so as to partially overlap. The meaning of “staircase” is synonymous with the case of the long holes 6.

  In the adhesive roll 1, the long holes 6 and the slits 10 are arranged so as to overlap each other by 5 mm in the winding direction D of the adhesive sheet 2. However, the overlapping width of the long hole and the slit is not particularly limited. It is sufficient that the long hole and the slit are overlapped so that the adhesive sheet can be easily separated. For example, it is preferably 3 mm or more and 7 mm or less.

The adhesive roll according to the present invention described above has the following effects.
That is, the adhesive roll 1 is arranged in a stepped manner so that a part thereof overlaps in the order of the cutout portion 8, the plurality of long holes 6, and the slit 10 from one side edge to the other side edge. Thereby, when peeling the used adhesive sheet 2 which appears on the surface of the adhesive roll 1, a user is parallel to the winding direction D toward the slit 10 located below the stairs from the notch part 8 located above the stairs. It is only necessary to peel off the adhesive sheet 2 in any direction. At this time, the pressure-sensitive adhesive sheet portion corresponding to the overlapping portion of the notched portion 8 and the adjacent long hole 6 is torn in a direction parallel to the winding direction D, and then the pressure-sensitive adhesive sheet 2 corresponding to the overlapping portion of the long holes 6 is wound. The adhesive sheet 2 corresponding to the portion where the long hole 6 and the slit 10 overlap is broken in the direction parallel to the winding direction D. That is, the location where the user substantially breaks is only four locations, and the pressure-sensitive adhesive sheet 2 can be peeled off with much fewer man-hours than the conventional pressure-sensitive adhesive roll. Moreover, since the overlapping part of the notch part 8, the some long hole 6, and the slit 10 has a certain amount of length, a user can tear without minding a direction, ie, can tear the adhesive sheet 2 easily. it can.

  In the pressure-sensitive adhesive roll of the present invention, not a slit (cut) but a long hole is formed as a means for separating the pressure-sensitive adhesive sheet.

  When slits (cuts) are formed as a means for separating the adhesive sheet, if the long hair wraps around the surface of the adhesive roll so as to straddle the slit with almost no substantial gap, the hair crosses the slit. It sticks to the adhesive sheet 2 firmly. When the pressure-sensitive adhesive sheet 2 is peeled off, the hair functions as a stopper, which may hinder the separation of the pressure-sensitive adhesive sheet.

  On the other hand, when a long hole 6 having a width is formed instead of a slit having a width as in the present invention, even when a long hair is wound so as to straddle the long hole 6, the hair in the portion of the long hole 6 is It will be in a floating state. For this reason, the force which is going to cut | disconnect an adhesive sheet acts also on the direction of hair, and it becomes easy for hair to peel from the surface of an adhesive sheet. This effect is higher when the plurality of long holes 6 are inclined with respect to the winding direction D. Therefore, the pressure sensitive adhesive sheet can be easily separated without being hindered from being separated.

  Furthermore, if a long hole 6 having a width is formed instead of a slit having no width, adhesion of hair or the like to the overlapping portion of the notch 8, the long hole 6 and the slit 10 can be reduced. In particular, in a portion where the long holes 6 are overlapped, a long hair or the like which becomes a main obstacle when peeling off needs to straddle the two long holes 6. However, straddling two long holes 6 reduces the adhesive surface and reduces the possibility of long hairs adhering. That is, by arranging the wide long holes 6 in a stepped manner so as to partially overlap, adhesion of hair or the like to the overlapping portion of the long holes 6 can be reduced. As already explained, when the user peels off the adhesive sheet 2, the overlapping portion is broken. If there is no deposit on the overlapping portion, the user can easily break the adhesive sheet 2.

  The manufacturing method of the adhesive roll of this invention is not specifically limited. For example, after winding a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer on one surface of a substrate sheet around a core, punching out a desired position of a roll-shaped pressure-sensitive adhesive sheet to form a long hole or a notch, a roll shape It can manufacture by the method of making a slit in the desired position of this adhesive sheet, and forming a slit.

  The pressure-sensitive adhesive roll of the present invention can be suitably used as a pressure-sensitive adhesive roll for room cleaning.
