Description

  In this device, an adhesive sheet formed of a transparent plastic film coated with an adhesive on the back is attached to the surface of an adherend such as luggage, and slips are interposed between the surface of the adherend. This is a cover for slips to be enclosed, and is a pressure-sensitive adhesive sheet for cover for slips for the purpose of resource saving that does not require release paper.

  In general, when a delivery company receives a package from a client and delivers it to a receiver, slips such as an invoice and a delivery note are attached to the package. In order to prevent and protect the slips, they are sealed in a bag cover made of a transparent plastic film, and this cover is affixed to the luggage with an adhesive applied on the back.

  For example, as a general example, there is a delivery slip holder as shown in Japanese Utility Model Publication No. 62-13091. This is done by heat-welding one side of a transparent plastic film cover on a transparent plastic film base and holding the other side with an adhesive, and interposing slips between the film base and the film cover. The holder is open to the sides.

  However, in this case, a film base and a film cover are required to form the holder, one side is thermally welded, the other side can be peeled off to enclose slips, and an adhesive layer for fixing after encapsulation In addition, the structure is complicated, such as being held by a release paper called a backing sheet in order to protect the film-based pressure-sensitive adhesive, and the material cost is high. Further, the release paper is only treated as dust after the holder is peeled off. In recent years, resource saving and cost reduction have become issues, and materials that do not generate garbage are required.

Japanese Utility Model Publication No. 62-13091

  The present invention aims at obtaining a slip cover that can reduce distribution costs and achieve resource saving, and for a slip cover that achieves reliable holding so that slips enclosed during transportation are not dropped. An adhesive sheet is provided.

  For this reason, the present invention forms an enclosing portion for slips between the surface of the adherend by attaching an adhesive sheet based on a transparent plastic film to the adherend that is a load. Is the gist.

  That is, the present invention according to claim 1 forms a band-like pressure-sensitive adhesive layer having a strong adhesive force on both sides of the back surface of a cover base material made of a transparent plastic film having a release coating layer having a release treatment on the surface. In the middle region sandwiched between the adhesive layers on both sides, a non-adhesive part is interposed between the left and right sides to form a re-peeling adhesive layer that can be re-peeled, making a pressure-sensitive adhesive sheet for slip covers without release paper .

  Further, the present invention according to claim 2 cuts into a slip cover on one sheet across the adhesive layer for both sides of the cover substrate, the re-peeling adhesive layer in the middle region, and the left and right non-adhesive portions. A separating line is formed.

  In the present invention, since an encapsulating portion that can enclose slips can be formed with an adhesive sheet made of a single sheet of plastic film, resources can be saved and cost can be reduced compared to the case of bags using two sheets of plastic film. Become.

  In addition, by forming a release coat layer on the surface, the adhesive on the back does not adhere even when the adhesive sheet is rolled up, and no release paper is required, further saving resources and reducing costs. I can plan.

  In addition, since the re-peeling adhesive layer is formed in the other intermediate area except for the belt-like pressure-sensitive adhesive layer on both sides of the back side, the sealed part can be held in a bag shape, and the adhesive strength by the re-peeling adhesive layer The slips enclosed in are not dropped out.

    Furthermore, since the enclosing portion is formed of the re-peeling adhesive layer, there is no problem in taking out the enclosing slips and enclosing again.

    In addition, since the strong adhesive layer which adhere | attaches to a to-be-adhered body is apply | coated to the both sides of a cover base material in strip | belt shape, there is no waste of an expensive adhesive.

  FIG. 1 is a rear view of a slip cover adhesive sheet 1 according to the present invention, and FIG. 2 is a cross-sectional view. The surface of a rectangular cover substrate 2 made of a transparent plastic film is peeled off by a known material such as a silicon coat. A coat layer is formed, and on the back surface of the cover base material 2, strip-like pressure-sensitive adhesive layers 4, 4 are formed along the left and right side directions, and sandwiched between the belt-like pressure-sensitive adhesive layers 4, 4. In the intermediate region 2c, a re-peeling adhesive layer 6 having a weak adhesive force that can be re-peeled with the non-adhesive portions 5 and 5 interposed on the left and right is formed.

  The band-like pressure-sensitive adhesive layers 4 and 4 are intended to adhere to the adherend, and therefore the width of the belt-like width can be reduced as much as possible without reducing the adhesive pressure. it can.

  As shown in FIG. 3, the slip cover adhesive sheet 1 is formed in a roll shape by forming separation lines 7 such as perforations for separating the adhesive sheets continuously formed in the longitudinal direction one by one. Taken and provided. In addition, the continuous ones that do not form perforations are used by cutting them one by one with a labeler or the like into an arbitrary width corresponding to the width of the slips to be enclosed.

  By being configured as described above, in use, the sheets are separated into adhesive sheets for covering slips, and after attaching the slips B to the re-peeling adhesive layer 6 on the back surface, strong adhesive strips on both sides The slips B are sealed to the adherend A surface by being firmly attached to the adherend surface A which is a load by the adhesive force of the layers 4 and 4.

  After enclosing, the slip cover 1 is pressed from the surface, the cover base 2 carries the slip B with the adhesive force of the re-peeling adhesive layer 6, and the peripheral portions 8, 8 where the slips do not exist are The re-peeling adhesive layer 6 is held on the surface of the adherend A and prevents the enclosed slips B from falling off (see FIG. 4).

  Note that the non-adhesive portion 5 ′ provided on one side of the cover base material 2 serves as a handle for removing the slip cover adhesive sheet 1 on the cargo receiving side, and facilitates the removal work.

  INDUSTRIAL APPLICABILITY The present invention is suitable for collection and delivery of luggage, can save resources, and contributes to a reduction in distribution cost as a slip cover adhesive sheet that enables cost reduction.

It is a rear view which shows the Example of the adhesive sheet for slips cover without a release paper of this invention. FIG. It is explanatory drawing of the state formed continuously and separable to the adhesive sheet for slips cover of one sheet with a perforation. It is explanatory drawing of the state which enclosed the slips and was adhere | attached on the to-be-adhered body. It is sectional drawing which shows the state with which the slips were enclosed.
