Description

  The present invention relates to a sticky note laminate and a method for manufacturing a sticky note laminate.

  A sticky note laminate is known in which a plurality of sticky notes are stacked and bound on the base end side, and a protective piece for protecting the adhesive surface is attached to the back side. As a method for manufacturing this kind of sticky note laminate, a method has been proposed in which sticky notes are punched out one by one from an elongated strip of paper, and these sticky notes are stacked and laminated to form a sticky note laminate (Patent Document 1).

JP 2000-310945

  Instead of the method of Patent Document 1, an adhesive is attached to the back surface in a state where a strip-shaped paper for sticky note formation is continuous, and this strip is wound around a rotating plate and laminated. It is also conceivable to break the portion with a breaking blade.

  However, since one side or both sides of the cutter are inclined, when the cutter is press-fitted into a film-like laminate, the surface of the sticky note laminate and the free end (tip) side of the sticky note laminate are shown in FIG. The angle θ with respect to the cut surface is an obtuse angle. If this happens, it will be difficult to pick up sticky notes one by one with your finger on the obtuse spot.

  In general, it is known that when a flat object is cut perpendicularly to the surface, the blade is made into a single blade and cut toward a portion (a portion for forming a tag stack) that cuts out a substantially vertical surface of the single blade. When the sticky note stack was cut out in such a way, the angle between the cut surface and the surface approached a right angle, but it did not become a complete right angle. This is considered because the blade edge of the cutter pushes and deforms the laminated body.

  In recent years, by using a synthetic resin as the material of a sticky note, a product made thinner than a conventional paper sticky note (normal thickness is about 0.1 mm) is commercially available. In order to reliably take such thin sticky notes one by one, it is desirable that the angle formed by the surface of the sticky note laminate and the cut surface on the free end side is at least a right angle, preferably an acute angle.

  In order to meet this demand, the applicant presses the jig T on the surface of the sticky note laminate already cut out as shown in FIG. 8, and applies pressure to the surface from the base end side to the tip end side, The angle between the surface and the cut surface was an acute angle. However, in this case, as shown in the figure, the displacement between the respective sticky notes became uneven, and the inconvenience that the cut surface was not smooth was observed.

  The first object of the present application is a sticky note laminate in which the base end portions of a plurality of sticky notes are bundled and a protective piece is attached to the back surface, and the angle formed between the front surface and the front end surface is an acute angle. Is to provide things.

  The second object of the present invention is to propose a method capable of easily manufacturing a sticky note laminate in which the angle between the surface and the tip surface is an acute angle.

The first means is a sticky note laminate,
A plurality of sticky notes having a thickness of 0.08 mm or less are stacked and bonded with an adhesive layer 6 formed on the back surface of the base end portion 4a of each sticky note. A protective piece 8 is attached to protect the surface.
Further, the angle θ between the front end surface 2C of the sticky note laminate 2 and the surface 2A of the sticky note laminate is set to an acute angle.

  This means proposes that the angle θ between the front surface and the front end surface is an acute angle in a sticky note laminate in which a plurality of sticky notes are bound on the base end side and a protective piece is attached to the back surface. As a result, as shown by an imaginary line in FIG. 2, when the finger is put on the front end surface, the finger is surely touched with the most sticky note, and one sticky note can be effectively taken out. The upper limit of the thickness of the sticky note is determined to be greater than this, and even if the tip surface is perpendicular to the surface or the finger is placed on the uppermost sticky note, the fingertip does not slip. This is because a sticky note can be taken out and it is not necessary to have a structure as in the present invention. The lower limit value of the sticky note thickness is a practical lower limit value that enables the material to be formed into a sticky note shape.

  The “sticky note” is preferably formed of a synthetic resin, but can be formed of a general material such as paper. The “protective piece” is a means (so-called release paper or the like) for protecting the adhesive layer of the backmost sticky note and easily separating the sticky note laminate from the installation surface.

  The second means includes the first means, and the angle θ is set to 85 ° or less and 75 ° or more.

  This means proposes a suitable range of the angle θ between the surface of the sticky note laminate and the tip surface. What is important in this numerical range is the upper limit value of the angle, and even if the angle is slightly smaller than the right angle, the effect of locking the finger to the uppermost sticky note can be sufficiently exerted. The lower limit value of the numerical range is an inclination angle of the tip surface that can be realized by using a cutter described later.

The third means is
A step of laminating an elongated tape 32 having an adhesive layer on a part of the back surface in the longitudinal direction, and affixing the protective piece 8 to the back side of the tape laminate 38 to form a tape laminate with protective pieces;
The tape laminated body is cut with a cutter at two places, a bonded portion bonded with an adhesive and a non-bonded portion, and a tape laminated body portion with protective pieces at two cut portions is used as a base end portion 4a. It consists of the process of making a sticky note laminate bound in
For the tape laminate, inserting a cutter from the protective piece side;
The cutter 42 for press-fitting into a non-joined portion is a single blade having a main inclined surface 42a on one side of the blade body, and the main inclined surface 42a is directed to a place where a sticky note is formed.

  In this means, a method suitable for manufacturing the sticky note laminate according to the first means or the second means is proposed (see FIG. 3). As shown in FIG. 5, the first cutter 42 for press-fitting into a non-joined portion of the tape laminate is a single blade having an inclined surface 42a mainly on one surface of the blade body. It is pointing to the side. The inclined surface 42a also has a function of giving an inclination to the cut surface of the tape laminate. The “single blade” referred to in the present specification includes one provided with an auxiliary inclined surface shorter than the main inclined surface on the side opposite to the main inclined surface for protecting the cutting edge. This will be described later.

  According to the first aspect of the invention, since the angle θ between the tip surface 2C of the sticky note laminate and the surface 2A of the sticky note laminate is an acute angle, even if each sticky note is thin, it can be taken one by one. it can.

  According to the invention relating to the second means, since the angle of the sticky note stack is set to 85 ° or less, the operation of taking the sticky notes one by one becomes easier.

  According to the invention relating to the third means, the tape laminate having the protective piece on the back surface is inserted with a single blade with the inclined surface facing the sticky note forming portion from the back surface side, so the angle between the surface 2A and the tip surface 2C is A sticky note laminate having an acute angle can be easily produced.

  1 to 2 show a sticky note laminate 2 according to an embodiment of the present invention. This sticky note laminate 2 is formed by a plurality of sticky notes 4 having the same shape, which are stacked in the vertical direction, and a protective piece 8 attached to the back surface of the lowest sticky note.

  The sticky note 4 has an adhesive layer 6 on the back surface of each base end portion 4a (see FIG. 6), and is bonded to each other via the adhesive layer. The sticky note 4 is formed of a thin film of synthetic resin such as PP (polypropylene) or PET. The thickness of this film is smaller than the thickness of a general paper sticky note, for example, 0.03 mm to 0.08 mm, preferably 0.04 mm.

  The protective piece 8 covers the entire lower surface of the lowermost sticky note. The protective piece 8 can be formed of paper, for example.

  As shown in FIG. 1, the front surface 2A and the back surface 2B of the sticky note laminate 2 are parallel to each other, and the tip surface 2C of the sticky note laminate 2 has a certain angle θ (<90 °) between the front surface 2A. Then tilted. As a result, the sticky notes 4 can be taken out one by one as shown by the imaginary line in FIG.

  A suitable angle θ between the front end surface 2C and the surface 2A of the sticky note laminate is 85 ° to 75 °, and particularly preferably 80 °. From the principle of the invention, even when the angle θ is 75 ° or less, the ease of removal does not change, but the sticky note lengths are uneven on the upper layer side and the lower layer side of the sticky note laminate, and when the laminate is punched with a cutter described later This causes inconveniences such as an increase in resistance.

  3 to 6 show a method for manufacturing the sticky note laminate 2 according to the present invention.

  FIG. 3 shows a process for producing a tape laminate for producing the sticky note laminate 2. In FIG. 3A, reference numeral 30 denotes a roll wound with a tape 32 which is a sticky note material. 34 is an adhesive discharge means, and attaches an appropriate number of belt-like adhesive layers 6 to one side of the tape 32 in parallel with the longitudinal direction of the tape as shown in FIG. Reference numeral 36 denotes a rotating plate capable of rotating around the rotation axis O. By attaching the tip of the tape 32 to the rotating plate and then rotating the rotating plate, the tape 32 is wound around the rotating plate 36 to form a tape laminate 38. In the drawing, for the sake of simplicity, the tape 32 to which the two adhesive layers 6 are applied is drawn, but it is preferable to form a large number of adhesive layers 6 by increasing the width of the tape.

  FIG. 4A shows a process of attaching the two protective pieces 8 to portions corresponding to the front and back surfaces of the rotating plate 36 in the tape laminate 38. FIG. 4B shows a step of cutting the tape laminate wound around the rotating body at an appropriate location. The cutting location may be one location or multiple locations. As a result, a tape laminate including a plurality of sticky note laminate formation portions is cut out.

  5 and 6 show a process of punching the sticky note laminate 2 from the tape laminate 38 one by one. Of the tape laminate, the joined portion 38a joined by the aforementioned adhesive layer is cut by the second cutter 44, and the non-joined portion 38b is cut by the first cutter 42, respectively.

  As shown in FIG. 7, the first cutter 42 is a single blade having a large inclined surface (main inclined surface) 42a on one surface side. “Single blade” generally has the meaning that a blade is attached only to one side of the blade body, and the meaning that a blade is attached only to one side edge in the width direction of the blade body. Used to mean However, since the strength of the blade edge may be insufficient if it is a complete single blade, in the illustrated example, a very short auxiliary inclined surface 42b is also provided on the other surface side of the blade body. By placing the first cutter with the inclined surface facing the sticky note forming portion and cutting the tape laminate, the sticky note laminate 2 can be back-lined. In addition, about the 2nd cutter 44, the double blade is used in the example of illustration.

  A tape holding means (not shown) may be provided between the first cutter 42 and the second cutter 44. By sticking in two cutters from the protective piece side (back side) of the tape laminate, the sticky note laminate can be removed. The angle θ between the surface 2A and the tip surface 2C of the sticky note laminate is an acute angle.

[Example]
9 and 10 show an embodiment of the present invention. FIG. 9 shows the form of the sticky note laminate actually manufactured by the applicant and the form of the first cutter 42. This first cutter is conventionally known, and has an overall thickness D ₁ = 0.7 mm, a main inclined surface (large blade surface) 42a on the front side, and an auxiliary inclined surface (small blade surface) 42b on the back side. Have. Length _{H 2} of length _{H 1} and a small blade face of the large blade surface is _{H 1 = 1mm, H 2 =} 0.2mm , respectively. The angle β formed by the inclined surfaces of the blades with respect to the vertical direction is 29 °. However, these configurations can be changed as appropriate.

  In the prototype example, a laminate of 25 PP tapes having a thickness of 0.04 mm was cut with the first cutter 42. As a result, a sticky note laminate having an angle θ = 80 ° between the front end surface 2C and the surface 2A was obtained. The additional angle of θ, that is, the angle α formed between the front end surface of the tag stack and the vertical direction is 10 °, which is smaller than the inclination angle (28 °) of the main inclined surface 42a.

  From this prototype, when it is intended to produce a sticky note laminate having an angle α between the front end surface 2C and the vertical direction, the inclination angle β of the blade of the main cutter 42 may be made larger than the desired angle α. I understand.

  FIG. 10 schematically shows the horizontal direction of the end face of each tag in the tag stack. In the drawing, the end face of each sticky note is drawn in a staircase pattern, but it is unclear whether or not it actually has this shape. Since the angle α between the front end surface and the vertical direction is 10 ° and the thickness of each sticky note is d = 0.04 mm, the deviation Δw between the end faces of adjacent sticky notes is Δw = d × tan θ = 0.007 mm. .

  The applicant experimented how much it contributed to the ease of turning a sticky note by tilting the tip end face of the sticky note laminate by about 10 ° with respect to the vertical direction. In order to make the test conditions the same, whether subjects with different ages peeled off the protective strip from a single sticky note laminate can be turned from the front side and the back side, respectively, and whether the sticky notes can be turned one by one I investigated.

  The results are shown in Table 1 below. The event that can take one sticky note is indicated by ○, the event that two sticky notes are taken is indicated by Δ, and the event that the sticky note cannot be turned at all is indicated by ×.

  As described above, even when the angle α formed between the front end surface of the sticky note laminate and the vertical direction is about 10 °, a remarkable difference was observed between the case where the sticky note is turned from the front side and the case where the sticky note is turned from the back side.
