A second object of the present invention is to provide a portable dust remover which does not require a gripping member which is troublesome to attach, has a simple structure, and can be mass-produced inexpensively and easily.

[0006]

The pressure-sensitive adhesive sheet of the present invention for achieving the first object comprises a sheet body having a pressure-sensitive adhesive surface formed on one or both surfaces, and a pressure-sensitive adhesive surface for covering the pressure-sensitive adhesive surface. And a cover sheet releasably adhered to the sheet body, wherein the sheet body has flexibility, and is provided at one side edge in the adhesive surface region, from the end of the adhesive surface region. Also has a start point and an end point on the inside, draws a locus on the center side of the adhesive surface area, and at least one cut where the locus does not intersect is formed, when peeling the cover sheet from the sheet body, the sheet The portion surrounded by the cut in the main body is not peeled off but remains adhered to the cover sheet, and a separation preventing piece that prevents the progress of peeling is formed.

Further, the pressure-sensitive adhesive sheet of the present invention is a laminate comprising a sheet body having a pressure-sensitive adhesive surface formed on one or both surfaces, and a cover sheet removably adhered on the pressure-sensitive adhesive surface to cover the pressure-sensitive adhesive surface. Body, the cover sheet is flexible, having a start point and an end point on one side edge in an area on the cover sheet overlapping the adhesive surface, inside the end of the area, At least one cut is drawn on the center side of the area, where the track does not intersect, and when the cover sheet is separated from the sheet body, the portion surrounded by the cut of the cover sheet does not peel. There is also a type in which an anti-separation piece is formed that remains adhered to the sheet body and prevents the progress of peeling.

On the other hand, a portable dust collector according to the present invention for achieving the second object has a sheet body having an adhesive surface formed on one or both surfaces, and a sheet body having an adhesive surface for covering the adhesive surface. A laminate comprising a cover sheet that is releasably adhered, and the sheet body has flexibility, and is provided at one side edge in the adhesive surface region, more than the end portion of the adhesive surface region. Having a start point and an end point on the inside, drawing a locus on the center side of the adhesive surface area, and at least one cut where the locus does not intersect is formed, the cover sheet side surface of the laminate is on the adhesive surface When the cover sheet is peeled off from the sheet body, the part surrounded by the cut of the sheet body remains adhered to the cover sheet without peeling, and a separation preventing section that hinders the progress of peeling is provided. Is formed.

The portable dust collector of the present invention includes:
A laminate comprising a sheet body having an adhesive surface formed on one or both surfaces and a cover sheet removably adhered on the adhesive surface to cover the adhesive surface, wherein the cover sheet has flexibility. And has a start point and an end point inside one end of the area on the cover sheet that overlaps the adhesive surface, inside the end of the area, and draws a locus on the center side of the area, and At least one cut not intersecting is formed, the cover sheet side surface of the laminate has an adhesive property to the adhesive surface, and when the cover sheet is peeled from the sheet body, the cover sheet has There is also a type in which a portion surrounded by a cut remains adhered to the sheet body without being peeled off, and a separation preventing piece that prevents the progress of peeling is formed.

[0010] In the pressure-sensitive adhesive sheet of the present invention, at least one of the sheet body and the cover sheet has flexibility. And when the sheet body has flexibility, one side edge in the adhesive surface region has a start point and an end point inside the end portion of the adhesive surface region, and the central portion side of the adhesive surface region , And at least one cut where the trajectory does not intersect is formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an example of a portable dust remover to which the pressure-sensitive adhesive sheet of the present invention is applied.
Is a side view and 1C is a bottom view. In this dust collector, the entirety of one side of the rectangular sheet body 1 is an adhesive surface 7, and the adhesive surface 7 is covered with a cover sheet 2 having the same shape and size as the sheet body. Contact surface of cover sheet 2 with adhesive surface 7 (inner surface of cover sheet) 8
Can be easily peeled off from the adhesive surface when used, but has sufficient adhesive strength to protect the adhesive surface.

When the pressure-sensitive adhesive sheet is a dust remover, its shape is usually rectangular or square, and its size is such that two or three fingers can be inserted when it is made cylindrical after peeling. The sheets have the same shape and size. However, the shape and size of the sheet body, the cover sheet, and the completed pressure-sensitive adhesive sheet are not particularly limited. For example, as shown in FIGS. 5 and 6, the shape and size of the sheet body and the cover sheet are different. May be. Further, the adhesive surface may be provided on both surfaces of the sheet body, and each of the adhesive surfaces may be covered with a cover sheet, or the adhesive surface may be provided only on a part of one or both surfaces of the sheet body.

The materials of the sheet body and the cover sheet are not particularly limited, and for example, a flexible or non-flexible sheet made of paper, synthetic resin, or metal can be used. The adhesive for forming the pressure-sensitive adhesive surface can be selected according to the use of the pressure-sensitive adhesive sheet, but in the case of a dust remover, it is preferable to use a material having relatively low tackiness. The inner surface of the cover sheet that can be separated from the adhesive surface can be formed, for example, by laminating silicon paper on the base material of the cover sheet.

In the pressure-sensitive adhesive sheet and the portable dust collector of the present invention, at least one of the sheet body and the cover sheet needs to have flexibility. When the sheet body is flexible, as shown in FIG. 5A, the start point 5 and the end point are located on one side edge in the adhesive surface area of the sheet body 1 and inside the end of the adhesive surface area. 6, a locus is drawn on the center side of the adhesive surface area, and a cut 4 where the locus does not intersect must be formed.

On the other hand, when the cover sheet has flexibility, as shown in FIG. 6C, one side edge in the area on the cover sheet 2 overlapping the adhesive surface is located inside the edge of the area. It is necessary to have a starting point 5 and an ending point 6, draw a locus on the center side of the area, and form a cut 4 where the locus does not intersect. Here, “the area on the cover sheet that overlaps the adhesive surface” means an area on the cover sheet where the adhesive surface is projected when the adhesive surface of the sheet body is covered with the cover sheet.

In the dust collector shown in FIG.
Is an adhesive surface, and the cover sheet 2 has the same size and shape as the sheet body. Then, as shown in FIG. 1A, on one side edge of the sheet body 1,
It has a start point 5 and an end point 6 inside the end of the seat body,
A cut 4 is formed in the center of the sheet body, where a locus is drawn and the locus does not intersect. In addition, some or all of the cuts may penetrate to the other stacked sheet.

The anti-separation sections are preferably arranged as straight as possible along one side edge of the adhesive surface area or the area overlapping the adhesive surface. From this viewpoint, in the present invention, as shown in FIGS. 5A and 6C, it is preferable that the start points 5 and the end points 6 of all the cuts are arranged along a straight line perpendicular to the direction in which the peeling proceeds. That is, in the present invention, usually, the peeling starts from the side edge portion opposite to the side edge portion with the cut, the peeling proceeds toward the side with the cut, and the adhesion is maintained on the side with the cut. The peeling is stopped when a part of the peeling still remains, but a straight line perpendicular to the direction of the progress of such peeling is defined as a reference of the position where the start point and the end point of the break should be set, and this standard The start point and the end point are set on a position that does not greatly deviate from the straight line, ideally on this straight line.

The size of the cut, the shape and the number of trajectories, etc. are not particularly limited. Regarding the size of the cut, if it is too small, it is not possible to secure sufficient adhesive force to prevent the progress of peeling, but if it is too large, the adhesive surface cannot be used effectively. The shape of the trajectory can be exemplified by a substantially arc shape or tongue shape as shown in FIG. 1, a square shape as shown in FIG. 5, and a triangular shape as shown in FIG. Is preferred. As for the number of cuts, if the size is about the size of a palm like a portable dust collector, it is usually preferable to set the number to about three.

In the present invention, the perforation 3 penetrating the sheet body and the cover sheet near the start and end points of the cut.
, The effect of preventing separation by the separation preventing section can be enhanced. When forming a perforation, the perimeter of the perforation hole of the other sheet fits into the perforation hole of one sheet. For this reason, the perforations themselves resist the progress of peeling.

The perforation 3 is formed at a position crossing the cut 4, or at a position slightly closer to the end on the side where the cuts are arranged when viewed from the position where the start and end points of the cut are located. However, it is preferably formed on a straight line connecting the start point and the end point. If there is a straight line serving as a reference for the start point and the end point of the break, it is preferable to form a perforation along the reference straight line, and it is particularly preferable to form a perforation on the reference straight line. The perforations are preferably formed from one end to the other end of the adhesive surface region, as shown in FIGS.

In the present invention, not only the sheet body or the cover sheet forming the cuts, but also the sheet on the side where no cuts are formed can be a flexible sheet. In particular, when the adhesive sheet is a portable dust collector, it must be rolled into a cylinder when used, but if both the sheet body and the cover sheet are flexible, they are rolled into a cylinder. Is preferred. From such a viewpoint, in the dust collector of FIG. 1 as well, both the sheet body 1 and the cover sheet 2 are flexible sheets.

When using this dust collector, the cover sheet must first be peeled off from the sheet body to expose the adhesive surface. When the cover sheet is peeled off from the end where the cut is not formed, the peeling eventually reaches a cut near the other end. Then, as shown in FIG. 3, the separation preventing section 9 is formed due to the cut,
The adhesion between the sheet body and the cover sheet at the section is maintained. As a result, the progress of the peeling stops on a straight line connecting the start point and the end point of the cut, and the two sheets having flexibility are bent with the straight line as a base line. At this time, the perforations 3 on the straight line connecting the start point and the end point of the break assist the separation preventing action of the separation preventing section 9 formed due to the cut. As described above, in the pressure-sensitive adhesive sheet and the portable dust collector of the present invention, the cuts (separation preventing sections) are provided.
Or the cooperative action of the cuts and perforations prevents the sheet body from completely separating from the cover sheet at the time of peeling.

Next, as shown in FIG. 4, the adhesive surface (the inner surface of the sheet body) 7 of the sheet body 1 and the inner surface 8 of the cover sheet are rolled into a cylindrical shape so that they face outward, and the separation preventing section 9 is formed. Adhesive surface 7 of sheet body 1 encountered on the opposite side of position
When the edge of the cover sheet 2 and the edge of the outer surface of the cover sheet 2 are brought into contact with each other and bonded, a form usable as a dust collector is completed. In order to use the completed cylindrical dust collector, a finger is inserted into the inside of the cylinder and gripped, and the adhesive surface on the outer side of the cylinder is pressed against a surface to be cleaned such as clothes. At this time, since the finger can be gripped by inserting a finger inside the cylinder, the dust collector of the present invention does not require a band or bag structure for gripping.

The surface of the pressure-sensitive adhesive sheet and the portable dust collector of the present invention, the pressure-sensitive adhesive surface, and the inner surface of the cover sheet can be provided with characters, pictures, and the like. For example, by displaying various advertisements on the surface of the sheet body (the outer surface of the sheet body) or the surface of the cover sheet (the outer surface of the cover sheet), it can be suitably used as so-called novelty goods. In addition, it may be displayed on the sticky surface (the inner surface of the sheet body) or the inner surface of the cover sheet that the lottery hit or missed.

The pressure-sensitive adhesive sheet and the portable dust collector of the present invention can be manufactured, for example, by the following method. First, as raw material sheets for the sheet body and the cover sheet, a predetermined raw material is printed in advance, and a long raw material sheet wound in a roll is prepared. Next, the raw material sheet for the sheet body and the raw material sheet for the cover sheet are respectively unreeled from a roll, and both are bonded and laminated. next,
After making a cut and perforation at a predetermined position of the laminated long sheet, punching a sheet of a predetermined shape and size from the long sheet, the adhesive sheet or the portable dust collector of the present invention is completed. I do.

In producing the pressure-sensitive adhesive sheet and the portable dust collector of the present invention, a step for completely fixing the edge of the pressure-sensitive adhesive surface of the sheet body and the edge of the area on the cover sheet overlapping the pressure-sensitive adhesive surface; For example, since there is no need for a step of applying a strong adhesive for fixing to this portion, mass production can be performed at low cost and easily.

[0031]

As described above, the sheet body and the cover sheet of the pressure-sensitive adhesive sheet of the present invention do not separate at the time of peeling even though both ends are not fixed. Moreover, the structure for preventing separation is very simple, and is suitable for mass production.

On the other hand, the portable dust collector of the present invention is in the form of a thin adhesive sheet before use, so that it is convenient to carry. Further, it has a very simple structure, and does not require a band or a bag structure for gripping. And the dust collector of the present invention is compact, has high practicality,
Because production cost is low and suitable for mass production,
It can be suitably used as so-called novelty goods.
