Description

  In this invention, a pressure-sensitive adhesive sheet made of a transparent film in which a pressure-sensitive adhesive is partially coated on the back surface is attached to a surface of an adherend such as a baggage, and a slip is interposed between the surface of the adherend and enclosed. This is an adhesive sheet feeder that provides a slip cover adhesive sheet that does not require release paper to be pulled out from a sheet roll and cut to an appropriate width.

  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 the slips from falling out and to protect the slips, the slips are sealed in a bag-like cover made of a transparent film, and the bag-like cover is attached to the luggage with an adhesive applied on the back surface. However, release paper is used for the purpose of protecting the adhesive, but the release paper is later treated as waste, which is contrary to the recent demand for resource saving and cost reduction.

Therefore, the present applicant is able to reduce the distribution cost and can achieve resource saving, and the slip cover adhesive that can securely hold the slips that are enclosed during the transportation is not lost. A sheet was proposed (utility model registration No. 3111629).
Utility Model Registration No. 311629

  In this device, a band-shaped adhesive layer having strong adhesive force is formed on both sides of the back surface of a cover base material made of a transparent film having a release coating layer having a release treatment on the surface, and the adhesive layers on both sides are formed. A slip cover adhesive sheet without release paper having a re-peeling adhesive layer that allows re-peeling in the middle region sandwiched between the non-adhesive parts on the left and right sides.

  The present invention cuts the adhesive sheet into an appropriate width for each sheet according to the width of the slips to be sealed in the field where the previously proposed adhesive sheet for slip covers is used, and makes it easier to use. The gist is to provide a sheet feeder, and to provide an adhesive sheet feeder that is not disposable and can be used for a long period of time because of demands for resource saving and cost reduction.

  Therefore, the present invention accommodates an adhesive sheet roll for slip covers (hereinafter simply referred to as an adhesive sheet roll) wound in a roll shape in a slender box-shaped holder so as to be rotatable and drawable. A serrated cutter blade that can be cut to any width according to the width of the slips to be used is provided at the front edge of the lid of the holder that can be freely opened and closed.

  In addition, the saw blade has a sharp tip so that the cutter blade does not lose its sharpness due to adhesion of the adhesive along with long-term use.

  Furthermore, in order to make it possible to replace the cutter blade, the cutter blade is mounted so as to be replaceable by a mounting member provided at the edge of the lid.

  In the present invention, the pressure-sensitive adhesive sheet drawn from the pressure-sensitive adhesive sheet roll in the elongated box-shaped holder can be cut to any width according to the width of the slip to be used at the shipping site for packing. Can save resources, meet resource-saving requirements, and contribute to the efficiency of shipping work.

  In addition, since the pressure-sensitive adhesive sheet having a release coating layer formed on the surface is a pressure-sensitive adhesive sheet roll wound in a roll shape, the pressure-sensitive adhesive on the back surface does not adhere and does not require a release paper, further saving resources and reducing costs.

  FIG. 1 is a front view of an adhesive sheet feeder 1 for slip covers according to the present invention, and an adhesive sheet roll R in which an adhesive sheet A is wound around a winding core is rotatably held in an elongated holder 2. ing. The holder 2 has an elongated box shape, has a volume that the sheet roll R can be gently accommodated, has an upper surface that allows the adhesive sheet roll R to be exchanged, and the adhesive sheet A to be drawn out from the adhesive sheet roll R. It is also a drawing outlet 2a.

  A cutter blade 3 that cuts the adhesive sheet A drawn out from the holder 2 with an appropriate width is attached to the front edge 4 a of the lid 4 by a mounting member 5 so as to be replaceable. The cutter blade 3 includes a long blade portion 3a having the length of the front end edge 4a of the lid body 4, and the blade portion is formed in a sawtooth shape 3b. The lid 4 is attached to the rear edge 2b of the holder 2 at the rear edge 4b so as to be opened and closed.

  In addition, the pressure-sensitive adhesive sheet roll R used in the present invention has a release coat layer 11 made of a material such as a silicon coat on the surface of a cover substrate 10 of a transparent film as shown in FIG. Adhesive layers 12, 12 having a band-like strong adhesive force are formed on the back side along the left and right side directions, and non-adhesive portions 14 are formed on the left and right sides in an intermediate region 13 sandwiched between the band-like adhesive layers 12, 12. , 14 is formed to form a re-peeling adhesive layer 15 having a weak adhesive force that can be re-peeled to form a slip cover adhesive sheet A.

  As shown in FIG. 4, the slip cover pressure-sensitive adhesive sheet A is continuously formed in the longitudinal direction, wound around the winding core in a roll shape, and provided as a pressure-sensitive adhesive sheet roll R.

  Next, the operation will be described. When the pressure-sensitive adhesive sheet feeder 1 of the present invention is not used, the pressure-sensitive adhesive sheet roll R is accommodated in the elongated holder 2 and the lid 4 is closed so as to cover the upper part of the holder 2 whose upper surface is opened.

  In use, the lid 4 of the holder 2 is lifted upward from the outlet 2a, the end of the adhesive sheet A is pulled from the adhesive sheet roll R and pulled out of the holder 2, and the width of the slips to be used is sufficiently covered. It is cut by pulling in the width direction so as to cross the adhesive sheet A with the cutter blade 3 of the front end edge 4a of the lid body 4 when it is pulled out by the width to be obtained (see FIG. 3).

  After cutting, the adhesive sheet A holds the cutting end Aa on the cutter blade, the rear end is continuous with the sheet roll R, and stands by in a state of closing the opening 2 a on the upper surface of the holder 2. The same operation as described above is repeated for drawing and cutting the pressure-sensitive adhesive sheet A in the next stage.

  As described above, in use, each sheet is cut into a sheet cover adhesive sheet A, and after the sheets B are temporarily held in the re-peeling adhesive layer 15 on the back side, strong adhesive strips on both sides. The slips B are securely attached to the adherend surface C, which is a load, by the adhesive force of the layers 12 and 12, and the slips B are sealed and held in the adherend C surface (see FIGS. 6 and 7).

  After sealing, the cover base material 10 is lightly pressed from the surface, so that the cover base material 10 holds the slips B lightly with the adhesive force of the re-peeling adhesive layer 15 formed in a band shape at the center portion and encapsulates it. The slips B are prevented from falling off.

It is a front view which shows the Example of the adhesive sheet feeder of this invention. It is the same side view. It is explanatory drawing of the state which pulled out the adhesive sheet from the adhesive sheet roll. It is a rear view of the slips adhesive sheet used by this invention. It is sectional drawing of the adhesive sheet used by this invention.
