Description

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

Adhesive cleaners equipped with adhesive rolls are widely known as indoor floor cleaning tools. 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 material sheet around a tubular winding core with the pressure-sensitive adhesive layer facing up.

In general, such an adhesive roll is formed with a large number of cuts (slits) in a direction orthogonal to the winding direction of the adhesive sheet. By forming the cut in the adhesive sheet in this way, a part of the adhesive sheet can be peeled off from the adhesive roll, and the adhesive sheet can be separated and discarded at the cut portion. As a result, the adhesive roll exposes a new adhesive surface and can be used for cleaning again.

For example, there is known an adhesive roll in which a perforation is provided straight from one side edge portion of the adhesive roll to the other side edge portion (see Patent Document 1). Further, there is known an adhesive roll in which cuts for cutting lines are provided in different steps (see Patent Document 2). Further, there is known an adhesive roll in which cut lines for cut lines are provided in different steps and in an oblique direction (see Patent Document 3).

However, in the adhesive rolls described in Patent Documents 1 to 3, when long hair or the like is wrapped around the surface of the adhesive roll, the hair may prevent the adhesive sheet from being separated.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide an adhesive roll capable of easily separating the adhesive sheet. More specifically, it reduces the adhesion of long hair or the like to the sheet portion related to the detachment of the adhesive roll, and even when the long hair adheres to the sheet portion related to the detachment of the adhesive roll, the adhesive sheet Make it easy to separate.

The pressure-sensitive adhesive roll of the present invention includes a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer on one surface of the base material sheet and a winding core for winding the pressure-sensitive adhesive sheet, and the pressure-sensitive adhesive sheet with the pressure-sensitive adhesive layer facing up. Is an adhesive roll wound around the winding core, and the adhesive roll is formed with a plurality of elongated holes extending from the surface side of the adhesive roll to the winding core, and the plurality of elongated holes are formed in each other. It is characterized in that it is arranged in parallel without being in contact with each other, and is arranged in a stepped manner so that the end regions partially overlap in the winding direction of the adhesive sheet.

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

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

In the adhesive roll of the present invention, slits from the surface side of the adhesive roll to the winding core are formed on other side edges, and the plurality of elongated holes and the slits are arranged in parallel without contacting each other. Moreover, it is preferable that the end regions are arranged in a stepped manner so as to partially overlap in the winding direction of the adhesive sheet.
In the adhesive roll of the present invention, it is preferable that the result of the lottery is displayed on the surface of the winding 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 when the long hair adheres to the sheet portion related to the separation of the adhesive roll, the adhesion is adhered. The sheet can be easily separated.

It is a figure which shows the use state 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 the other embodiment of the adhesive roll of FIG. 1 schematically. It is a perspective view which shows the other embodiment of the adhesive roll of FIG. 1 schematically.

Hereinafter, the adhesive roll of the present invention will be described with reference to the drawings. However, the same elements are designated by the same reference numerals, and the description thereof will be omitted.
As shown in FIG. 1, the adhesive roll 1 of the present invention is typically attached to a roller provided at the tip of a hook-shaped handle, and is mainly used for cleaning the floor in a room.
As shown in FIGS. 1 and 2, the adhesive roll 1 includes an adhesive sheet 2 and a winding 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 winding core 4 is formed in a cylindrical shape. The material is also not particularly limited. For example, cardboard, plastic, or the like, which has sufficient strength for wrapping the adhesive sheet, may be used.

As shown in FIG. 3, it is preferable that the result of the lottery is displayed on the surface of the winding core 4. With such a configuration, the result of the lottery appears when the adhesive sheet 2 is used up, and the playability of using the adhesive roll 1 can be improved. The method of displaying the lottery result is not particularly limited. For example, a method of printing characters such as "hit" and "missing" on the surface of the winding core 4 can be mentioned.

The pressure-sensitive adhesive sheet 2 is a sticky sheet having a pressure-sensitive adhesive layer on one surface of the base material sheet. The width of the base sheet may be appropriately set according to the purpose of the adhesive roll, and is not particularly limited. For example, it may be configured from 9 cm to 30 cm.

The material of the base sheet is also not particularly limited. For example, a flexible material such as paper or a plastic sheet can be preferably 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 material sheet, and the pressure-sensitive adhesive layer is not formed on the other surface. Then, it is preferable that a release agent layer is formed on the side of the base sheet on which the pressure-sensitive adhesive layer is not formed. For example, the formation of the release agent layer made of a silicone-based release agent facilitates the release of the pressure-sensitive adhesive sheet 2 from the pressure-sensitive adhesive roll 1.

As shown in FIGS. 1 and 2, the adhesive roll 1 is formed with a plurality of elongated holes 6 having the same shape and the same size, extending from the surface side of the adhesive roll 1 to the winding core 4. The number of elongated holes 6 is not particularly limited to three as long as it is plural (that is, two or more). “From the surface side of the adhesive roll to the winding core” means that the elongated holes 6 formed in the adhesive sheet 2 wound in a roll shape penetrate to the winding core. The plurality of elongated holes 6 are arranged in parallel without touching each other. In other words, it means that the plurality of elongated holes 6 and their extension lines are arranged in parallel and do not intersect with each other.

The elongated hole 6 may be formed by penetrating the winding core 4 from the surface side of the adhesive roll 1. That is, in this case, the elongated holes 6 are formed in the pressure-sensitive adhesive sheet 2 and the winding core wound in a roll shape. Then, the elongated hole 6 penetrates the adhesive sheet 2 and the winding core.

The elongated hole 6 is a hole having a constant width. The length of the elongated hole 6 is determined so as to fit in the width of the adhesive sheet 2 (that is, not to reach the side edge of the adhesive sheet 2). If the elongated holes 6 are 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 off from the side edge side of the pressure-sensitive adhesive roll 1, which is not preferable. Typically, the elongated holes 6 are formed to have a width of 5 mm in the lateral direction (the direction in which the adhesive sheet is wound). However, the width of the elongated hole in the lateral direction is not particularly limited. It suffices if a gap is formed so that the hair floats. For example, the width of the elongated hole 6 in the lateral direction is preferably 2 mm or more and 25 mm or less. Further, the width of the elongated hole 6 in the longitudinal direction may be 2 mm or more and 80 mm or less.

The elongated holes 6 are arranged at intervals of 10 mm in width. However, the distance between the elongated holes is not particularly limited. It suffices if the elongated holes 6 are arranged close to each other so that the adhesive sheet 2 can be easily separated. For example, it is preferably 5 mm or more and 15 mm or less.

The plurality of elongated holes 6 are arranged in a staircase pattern so that the end regions partially overlap each other in the winding direction D of the adhesive sheet 2. In the "stepped shape", a plurality of elongated holes 6 are arranged in a staircase manner, and the plurality of elongated holes 6 are gradually stepped from one side edge portion of the adhesive sheet 2 toward the other side edge portion. It means a shape that lowers.

As shown by the alternate long and short dash line in FIG. 2, in the adhesive roll 1, the elongated holes 6 are arranged so as to overlap each other by 10 mm in width in the winding direction D of the adhesive sheet 2. However, the overlapping width between the elongated holes is not particularly limited. It suffices if the elongated 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.

In another embodiment of the pressure-sensitive adhesive roll of the present invention, as in the pressure-sensitive adhesive roll 100 shown in FIG. 4, a plurality of elongated holes 106 are oriented in a direction orthogonal to the winding direction D of the pressure-sensitive adhesive sheet 102 (that is, the width of the pressure-sensitive adhesive sheet 102). The form arranged in parallel with the direction can be mentioned. However, as in the adhesive roll 1 shown in FIGS. 1 and 2, it is preferable that the plurality of elongated holes 6 are arranged in an oblique direction with respect to the winding direction D of the adhesive sheet 2. With such a configuration, the adhesive sheet can be easily separated with a small force.

The inclination angle of the elongated hole 6 with respect to the winding direction D of the adhesive sheet 2 is set to 10 °. However, the inclination angle of the adhesive sheet with respect to the winding direction is not particularly limited. It suffices if there is an inclination with respect to the winding direction. For example, it 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 winding core 4 is formed on one side edge of the adhesive roll 1. By forming the notch portion 8, it becomes easy to understand the starting point when the adhesive sheet 2 is peeled off.

"Wedge-shaped" means V-shaped. The side of the notch 8 closer to the elongated hole 6 (the end side of the adhesive sheet 2) is located in a direction orthogonal to the winding direction D of the adhesive sheet 2, and the side farther from the elongated hole 6 of the adhesive sheet 2 (the side far from the elongated hole 6 of the adhesive sheet 2). The winding source side of the 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 suggest to the user the direction in which the adhesive sheet 2 is to be peeled off.

In the adhesive roll 1, the notch 8 is formed so as to bite 20 mm from the side edge of the adhesive sheet 2 toward the center in the width direction. However, the size of the notch 8 is not particularly limited. It suffices if the size is such that the adhesive sheet 2 can be easily separated and the starting point when the adhesive sheet 2 is peeled off can be easily understood. For example, it is preferably 15 mm or more and 25 mm or less.

The notch 8 and the plurality of elongated holes 6 are arranged without being in contact with each other. In the adhesive roll 1, the notch 8 is arranged on the winding side of the adhesive sheet 2, and the plurality of elongated holes 6 are arranged on the end side of the adhesive sheet 2. In such a form, the pressure-sensitive adhesive sheet 2 can be separated by breaking the pressure-sensitive adhesive sheet 2 from the cutout portion 8 in the directions of the plurality of elongated holes 6.

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

In the adhesive roll 1, the elongated hole 6 and the notch 8 are arranged so as to overlap each other by a width of 5 mm in the winding direction D of the adhesive sheet 2. However, the overlapping width of the elongated hole and the notch is not particularly limited. It suffices if the elongated holes and the notches are arranged so as to be easy to separate the adhesive sheet. For example, it is preferably 3 mm or more and 7 mm or less.

In the adhesive roll 1, a slit 10 is formed in the other side edge portion of the adhesive roll 1 (the side edge portion on which the notch 8 is not formed) from the surface side of the adhesive roll 1 to the winding core 4. There is. 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 notch. 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 into the center side in the width direction by 20 mm from the side edge of the adhesive sheet 2. However, the size of the slit 10 is not particularly limited. A size that makes it easy to separate the adhesive sheet 2 is sufficient. For example, it is preferably 5 mm or more and 25 mm or less.

The plurality of elongated holes 6 and the slits 10 are arranged in parallel without being in contact with each other. In other words, it means that the plurality of elongated holes 6 and their extension lines, the slits 10 and their extension lines are arranged in parallel and do not intersect with each other.

In the adhesive roll 1, the plurality of elongated holes 6 are arranged on the winding source side of the adhesive sheet 2, and the slits 10 are arranged on the end side of the adhesive sheet 2. In such a form, the adhesive sheet 2 can be separated by breaking the adhesive sheet 2 from the direction of the plurality of elongated holes 6 in the direction of the slit 10.

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

In the adhesive roll 1, the elongated holes 6 and the slits 10 are arranged so as to overlap each other by a width of 5 mm in the winding direction D of the adhesive sheet 2. However, the overlapping width of the elongated hole and the slit is not particularly limited. It suffices if the elongated holes and the slits are arranged so as to be easy to separate the adhesive sheet. For example, it is preferably 3 mm or more and 7 mm or less.

As shown in FIG. 5, the width of the notch 8 in the lateral direction (the direction in which the adhesive sheet is wound) may be 5 mm to 25 mm. Further, the width in which the elongated hole 6 at the right end in the drawing and the notch 8 overlap may be 2 mm or more. In that case, the width at which the elongated hole 6 and the notch 8 overlap may be 2 mm to 15 mm. Further, the overlapping width of the elongated holes 6 may be 2 mm or more. In that case, the overlapping width of the elongated holes 6 may be 2 mm to 15 mm.
Further, the width of the plurality of elongated holes 6 in the lateral direction (the direction in which the adhesive sheet is wound) may be 2 mm or more and 25 mm or less.

Further, the shape of both ends of the elongated hole 6 is not limited to a circle, and may be a quadrangular shape or a triangular shape. Further, a slit which is a linear notch extending from the surface side of the adhesive roll to the winding core may be formed on one side edge portion of the adhesive roll, and the other side edge portion of the adhesive roll may be formed. A slit, which is a linear notch extending from the surface side of the adhesive roll to the winding core, may be formed. That is, slits 10 which are linear notches extending from the surface side of the adhesive roll to the winding core may be formed on both one side edge portion and the other side edge portion of the adhesive roll. Further, the slit 10 may be replaced with the elongated hole 6. The direction of the slit may not be directed to the elongated hole 6 but may be provided in a direction orthogonal to the side edge.

Further, a colored line (mark) 200 as a mark may be inserted along the side edge on the notch 8 side. Further, the colored line 200 may be any mark as long as it serves as a mark, and the color and shape are not particularly limited. Then, instead of the colored line 200, any one of an arrow, a character, and a pattern may be applied. This makes it easier for the user to recognize the direction of breaking.
Further, the shape of the notch portion 8 may be the same as that of the elongated hole 6.
The adhesive roll according to the present invention described above has the following effects.

That is, the notch 8, the plurality of elongated holes 6, and the slit 10 are arranged in a stepped manner so that some of them overlap each other in this order from one side edge of the adhesive roll 1 to the other side edge. As a result, when the used adhesive sheet 2 appearing on the surface of the adhesive roll 1 is peeled off, the user is parallel to the winding direction D from the notch 8 located on the upper side of the stairs toward the slit 10 located on the lower side of the stairs. All you have to do is peel off the adhesive sheet 2 in the correct direction. At this time, the adhesive sheet portion corresponding to the overlapping portion of the notch 8 and the adjacent elongated hole 6 is torn in the direction parallel to the winding direction D, and then the adhesive sheet 2 corresponding to the overlapping portion of the elongated holes 6 is wound. The adhesive sheet 2 is torn in a direction parallel to the direction D, and finally the adhesive sheet 2 corresponding to the overlapping portion of the elongated hole 6 and the slit 10 is torn in a direction parallel to the winding direction D. That is, the user only needs to substantially break the adhesive sheet at four locations, and the adhesive sheet 2 can be peeled off with a very small number of man-hours as compared with the conventional adhesive roll. Further, since the notch 8, the plurality of elongated holes 6, and the overlapping portion of the slit 10 have a certain length, the user can tear the adhesive sheet 2 without worrying about the direction, that is, the adhesive sheet 2 can be easily broken. it can.
In the adhesive roll of the present invention, elongated holes are formed instead of slits (cuts) as a means for separating the adhesive sheet.

When a slit (cut) is formed as a means for separating the adhesive sheet, if long hair wraps around the surface of the adhesive roll so as to straddle the slit with virtually no gap, the hair straddles the slit. It sticks firmly to the adhesive sheet 2. When the adhesive sheet 2 is peeled off, the hair functions as a stopper, which may prevent the adhesive sheet from being separated.

On the other hand, when the elongated hole 6 having a width is formed instead of the slit having no width as in the present invention, even if the long hair is wrapped so as to straddle the elongated hole 6, the hair is formed at the portion of the elongated hole 6. It will be in a floating state. Therefore, the force for separating the adhesive sheet also acts in the direction of the hair, and the hair is easily peeled off from the surface of the adhesive sheet. This effect is higher when the plurality of elongated holes 6 are inclined with respect to the winding direction D. Therefore, the adhesive sheet can be easily separated without being hindered from being separated.

Further, if the elongated hole 6 having a width is formed instead of the slit having no width, it is possible to reduce the adhesion of hair or the like to the overlapping portion of the notch 8, the elongated hole 6 and the slit 10. In particular, in a portion where the elongated holes 6 overlap each other, it is necessary for long hair or the like, which is a main obstacle when peeling off, to straddle the two elongated holes 6. However, straddling two elongated holes 6 reduces the adhesive surface and reduces the possibility that long hair adheres. That is, by arranging the long holes 6 having a width in a staircase pattern so as to partially overlap each other, it is possible to reduce the adhesion of hair or the like to the overlapping portion of the long holes 6. As described above, 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 method for producing the adhesive roll of the present invention is not particularly limited. For example, after winding an adhesive sheet having an adhesive layer on one surface of a base sheet around a winding core, a desired position of the roll-shaped adhesive sheet is punched out to form elongated holes or notches to form a roll-shaped adhesive sheet. It can be manufactured by a method such as forming a slit by making a notch at a desired position of the adhesive sheet of.

The adhesive roll of the present invention can be suitably used as an adhesive roll for indoor cleaning.
