Description

  The present invention relates to a seal having an attachable / detachable layer of an adhesive body to which an adhesive body such as another seal can be repeatedly attached to or detached from the attachable / detachable layer.

  Conventionally, the following method is known as an example in which a delivery seal or the like is repeatedly attached to cardboard or the like.

  As shown in FIG. 5A, a release layer 33 is formed on an upper cover 32 of a paper cardboard 31 used for delivery or the like. The release layer 33 is formed of silicon resin, and as shown in FIG. 5B, the release layers 33 and 35 are processed into various shapes according to the size of the delivery seal 34 and the like (for example, patents). Reference 1).

Japanese Utility Model Publication No. 3-49923 (Page 1, Fig. 1-3)

  As shown in FIG. 5A, since the conventional release layer 33 is formed on the upper cover 32 of the cardboard 31 after the cardboard 31 is formed, there is a problem that leads to an increase in the cost of the cardboard 31.

  In addition, since the location where the delivery seal 34 or the like is attached differs depending on the user according to the visibility and application of the delivery seal 34 or the like, in the structure in which the release layer 33 is formed on the cardboard 31 in advance, the seal is attached. There is a problem that the position is not flexible and the usability is poor. Further, when the release layer 33 is formed over a wide area of the cardboard 31 in order to solve the above needs of the user, there is a problem that further increases the cost of the cardboard 31.

  Furthermore, in addition to corrugated cardboard 31, in boxes used in logistics and containers used in medical institutions, public institutions, etc., a sticker on which a trader's name, name, etc. are written is repeatedly pasted, It has been peeled off.

  That is, in various living environments, the user's desire to stick or peel off a seal or the like many times varies. And it is not realistic from the viewpoint of cost to perform the peeling treatment on every part on the adherend side such as the corrugated cardboard 31 so as to satisfy those demands, and it is difficult to satisfy the convenience of the user such as the attaching part and shape. . In addition, there is a problem that the reuse rate of the adherend such as the cardboard 31 decreases due to the remaining adhesive material on the cardboard 31 side, the remaining seal itself, or the tearing of the cardboard 31 when the seal is peeled off.

  The seal having the removable layer of the pressure-sensitive adhesive body of the present invention, which is made in view of each situation described above, includes a base material, a removable layer formed on one main surface side of the base material, An adhesive layer formed on the other main surface opposite to the one main surface of the substrate, the removable layer contains a release material, and the removable layer has an adhesive strength higher than that of the adhesive layer. The adhesive layer is attached to an adherend, and another adhesive is attached to the removable layer in a removable manner.

  In the present invention, a sticker having a detachable layer is attached to an adherend such as cardboard so that a delivery sticker can be attached to or peeled off from the sticker many times. can do.

  Further, according to the present invention, a seal having a removable layer can be easily processed and pasted to a desired location on the adherend to a desired size, improving the convenience for the user, corrugated cardboard, etc. The reuse rate of the adherend can be improved.

  Moreover, in this invention, before using the seal | sticker which has a detachable layer, or when it is not in use, it can prevent the fall of the adhesiveness of the detachable layer by dust etc. by sticking a protective sheet with respect to a detachable layer.

  Further, according to the present invention, characters such as <position where the sticker is attached> can be printed on the surface of the base material, and the sticker has a detachable layer capable of displaying the intention of the user.

  In the present invention, the removable layer is peeled off by forming a peeling prevention layer on the side surface (end portion) of the seal having the removable layer, or by thermocompression bonding of the peripheral removable layer and the substrate. Can be prevented.

It is the schematic for demonstrating the usage method of the seal | sticker which has the removable layer of the adhesion body in embodiment of this invention. It is the schematic for demonstrating the usage method of the seal | sticker which has the removable layer of the adhesion body in embodiment of this invention. It is (A) sectional drawing for demonstrating the seal | sticker which has the removable layer of the adhesion body in embodiment of this invention, (B) It is sectional drawing. It is the schematic for demonstrating the cardboard which has a peeling layer in conventional embodiment.

  Below, the seal | sticker (it demonstrates as a detachable seal | sticker hereafter) which has the removable layer of the adhesive body which is one embodiment of this invention is demonstrated. FIG. 1A is a perspective view of a removable seal according to one embodiment of the present invention. FIG. 1B is a perspective view of a removable seal according to another embodiment of the present invention. 2 and 3 are perspective views for explaining how to use the removable seal shown in FIG. 1 (A) or (B).

  As shown in FIG. 1A, the removable seal 1 mainly includes a first base material 2, a removable layer 3 formed on the surface side of the first base material 2, and a first base material. 2, the adhesive layer 4 formed on the back surface side, the second substrate 5 bonded to the first substrate 2 on the surface side through the adhesive layer 4, and the back surface of the second substrate 5. It has the adhesion layer 6 formed in the side, the protective sheet 7 formed in the surface side of the removable layer 3, and the separator 8 formed in the back surface side of the adhesion layer 6. FIG.

  The first and second substrates 2 and 5 may be formed by, for example, processing paper, synthetic paper, or hologram paper into a sheet, or using PET (Polyethylene terephthalate), PP (Polypropylene), or PVC (Polyvinyl chloride) as a film sheet. Used by processing into a shape. The thickness is appropriately adjusted within a range of 500 μm or less, for example. And the company name etc. may be printed on the surface side of the 1st base material 2 or the 2nd base material 5, for example. Also, it is possible to print a sentence such as “This is where the sticker is placed” on the surfaces of the first and second substrates 2 and 5 to indicate the intention of the user.

  For the removable layer 3, for example, a desired material is selected from acrylic, silicone, fluorine, urethane, emulsion, resin, rubber, etc., and the prepared material is coated or printed on the surface of the first substrate 2, It is formed. The film thickness of the detachable layer 3 is appropriately adjusted, for example, in the range of 1 to 200 μm, and is used as a slightly adhesive layer having a lower adhesive strength than the adhesive layers 4 and 6 described later. .

  Moreover, in the removable layer 3, the grade of the slightly adhesiveness is adjusted by adjusting content of silicone, a fluorine, and urethane. Moreover, the peelability and water repellency of the removable layer 3 are also adjusted by adjusting the contents of silicone, fluorine, and urethane. For example, by increasing the silicone content, the peelability and water repellency of the removable layer 3 become stronger.

  And the peelability of the detachable layer 3 becomes stronger, so that an adhesive body having an adhesive layer such as a delivery seal, a gum tape, a double-sided tape, a label, etc. is repeatedly attached to or peeled from the surface of the detachable layer 3. It becomes easy to do. At this time, the detachable layer 3 is slightly tacky with a lower adhesive strength than the adhesive layer of the adhesive body such as a seal, and when the adhesive body is peeled from the removable layer 3, a part of the adhesive layer of the adhesive body is , It can be prevented from remaining on the top surface of the removable layer 3.

  In addition, since the water repellency of the removable layer 3 is increased, for example, even when the removable seal 1 is affixed to the surface of a container where cleaning work is essential, the adhesiveness of the removable layer 3 is deteriorated by water. Is prevented. And even after the cleaning operation, an adhesive such as a seal can be repeatedly applied to the detachable layer 3 and attached or peeled off.

  In addition, when the peelability and water repellency of the detachable layer 3 become too strong, the adhesive body easily peels off from the detachable layer 3 during use. According to the intention of the person, the pressure-sensitive adhesive body can be peeled off immediately, and the preparation is performed so that the pressure-sensitive adhesive body has an adhesive strength that does not peel off from the removable layer 3 during use.

  For the adhesive layers 4 and 6, for example, a water-soluble adhesive, an acrylic solvent, an acrylic emulsion, and a urethane solvent are appropriately selected and used depending on the use conditions. Alternatively, the above solvent may be appropriately selected, mixed and used. The film thickness of the adhesion layers 4 and 6 is suitably adjusted, for example in the range of 1-200 micrometers.

  And the adhesive layer 4 is used for joining the first base material 2 and the second base material 5, and even when the adhesive body is repeatedly attached to or detached from the removable layer 3, The first substrate 2 and the second substrate 5 have such adhesive strength that they do not peel off.

  Similarly, the adhesive layer 6 is used because the removable seal 1 is attached to an adherend such as an upper lid of a cardboard, and the adhesive body is repeatedly attached to the removable layer 3 or peeled off. However, the removable seal 1 has such an adhesive strength that it does not peel off from the top cover of the cardboard.

  As the protective sheet 7 and the separator 8, for example, craft paper, glassine paper, a sheet of a PET film with a silicone resin laid on the surface, and the like are appropriately selected and used. Their film thickness is appropriately adjusted, for example, within a range of 500 μm or less.

  The protective sheet 7 covers the surface of the removable layer 3, and the protective sheet 7 is peeled off from the surface of the removable layer 3 during use while maintaining the adhesiveness of the removable layer 3 when not in use. Similarly, the separator 8 is also peeled off from the adhesive layer 6 at the time of use.

  Unlike the structure of the two-layer base material of the removable seal 1 shown in FIG. 1 (A), the removable seal 10 shown in FIG. 1 (B) has a single-layer base material structure. The individual components of the detachable seal 10 are the same as the structure of the detachable seal 1 shown in FIG. 1 (A) described above. Refer to it.

  As shown in FIG. 2, the detachable seals 1 and 10 (hereinafter referred to as the detachable seal 1) shown in FIG. However, it can be easily processed into a desired shape and size by using scissors, a cutter knife, or the like, and can be attached to a desired location on a paper cardboard 11, for example.

  As shown in the figure, first, the removable seal 1 is cut into a desired shape, for example, a shape that is slightly larger than the delivery seal. Next, the removable seal 1 processed in a desired region of the upper lid 11A and the side surface 11B of the cardboard 11 is attached. The user can repeatedly apply or peel off the delivery seal on the removable seal 1.

  With this structure, it is possible to prevent the adhesive layer of the delivery seal from remaining on the top lid 11A and the side surface 11B of the cardboard 11 and to tear the top lid 11A etc. when the delivery seal is peeled off, and the cardboard 11 can be used repeatedly. .

  Further, the removable seal 1 is processed into a desired shape according to the use application of the user, and is attached to a desired location on the cardboard 11, so that the removable layer 3 on the cardboard 11 itself is not formed. The cost of the cardboard is prevented and the convenience is improved.

  On the other hand, the removable seal 1 can be attached to the side surface 11C of the cardboard 11 over a wide area. In this case, it is possible to repeatedly affix or peel off a seal with a company name seal or a list of stored items on the side surface 11C of the cardboard 11. For example, the user can store different storage items for each season with one cardboard 11 and can immediately grasp the storage items.

  Furthermore, the detachable seal 1 can be attached along a region where the upper lids 11A and 11D of the cardboard 11 are closed with gummed tape or the like. Also in this case, it is possible to prevent the adhesive layer such as the gum tape from remaining and the cardboard 11 from being broken, and the cardboard 11 can be used repeatedly. Moreover, the adhesiveness of adhesive layers, such as a gum tape, is maintained, and reuse of a gum tape etc. is attained.

  The removable seal 1 is attached to the cardboard 11, and when the cardboard 11 is not used, the protective sheet 7 (see FIG. 1) is attached to the removable layer 3 so that the removable layer 3 is protected by dust or the like. It can prevent that adhesiveness falls. Further, when the corrugated cardboard 11 is used again, the adhesiveness of the removable layer 3 can be improved by removing dust or the like attached to the removable layer 3 with a tape or the like.

  As shown in FIG. 3, the detachable seal 1 is affixed to the bottom surface 13A and the top surface 14A of the storage boxes 13 and 14 arranged one above the other. And since each detachable seal | sticker 1 overlaps, the side slip of a storage box can be prevented with the slight adhesiveness, and a storage box can be arrange | positioned stably and efficiently.

  In the present embodiment, the case where the removable seal 1 has the first base material and the second base material has been described. However, the present invention is not limited to this case. For example, the first base material and the second base material may be omitted, and a removable layer may be directly formed on the upper surface of the adhesive layer to be used as a base material-less structure.

  Moreover, although this Embodiment demonstrated the case where a cardboard was used as a to-be-adhered body to which the removable seal | sticker 1 is affixed, it is not limited to this case. As a to-be-adhered body, it can use for all storage cases etc., such as a plastic corrugated cardboard, a container, a foamed polystyrene case, a through box, a wooden box, etc. Other uses such as various posters and train advertisements installed on the premise that they will be replaced, places where the display of names etc. needs to be replaced according to the user in medical institutions and public institutions, and places where rental items are managed For example, the above-described removable seal 1 can be used.

  Further, in the present embodiment, the case where the removable seal 1 is formed in a sheet shape has been described, but the present invention is not limited to this case. It can also be used in the form of a roll such as a double-sided tape. In addition, various modifications can be made without departing from the scope of the present invention.

  Next, a seal having a removable layer of an adhesive body according to another embodiment of the present invention (hereinafter described as a removable seal) will be described. FIG. 4A is a cross-sectional view of a removable seal which is another embodiment of the present embodiment. FIG. 4B is a cross-sectional view of a removable seal which is another embodiment of the present embodiment.

  The removable seals 21 and 22 shown in FIG. 4 (A) or FIG. 4 (B) have the same components as those of the removable seal 1 shown in FIG. Constituent elements common to the seal 1 are denoted by the same reference numerals, and the description thereof is referred to.

  As shown in FIG. 4A, on the four side surfaces of the detachable seal 21, for example, an anti-peeling layer 23 is formed in an annular shape. The peeling prevention layer 23 is formed of varnish or medium ink, and is applied to the four side surfaces (cut surfaces) using a cutting blade (not shown) when the removable seal 21 is cut, for example. It is cured and formed by UV irradiation.

  As shown in the figure, the removable layer 3 is peeled off from the surface of the first base material 2 when the removable seal 21 is used by being formed at least on the side surfaces from the removable layer 3 to the adhesive layer 6. Is prevented. As described above, the detachable layer 3 is slightly tacky in consideration of the peelability of an adhesive body such as a tape, and the adhesive strength between the detachable layer 3 and the first substrate 2 is weakened.

  For example, when the removable seal 21 is affixed to an object to be cleaned such as a container used outdoors, the side surface (end) of the removable seal 21 is used during the cleaning operation. Part) is repeatedly rubbed with a cleaning tool such as scrubber. As a result, in particular, peeling easily occurs between the first base material 2 having a low adhesive strength and the detachable layer 3, but the peeling prevention layer 23 is formed on the four side surfaces of the detachable seal 21, so that Generation of peeling is prevented.

  As shown in FIG. 4B, a foil layer 24 is formed in an annular shape on the upper surface of the detachable layer 3 of the detachable seal 22 and at its peripheral edge. The foil layer 24 is, for example, a gold stamp or a silver foil for hot stamping, and is pressure-bonded to the upper surface of the removable layer 3 by using a hot press type hot stamping machine (not shown).

  At this time, the foil layer 24 is heated and pressed for about several seconds by the above machine, but the heat is transferred to the first base material 2 located below the foil layer 24, and at least, particularly, the adhesive strength is weak. The first substrate 2 and the removable layer 3 are thermocompression bonded. Note that the heating and pressurizing time may be lengthened and the first substrate 2, the adhesive layer 4, the second substrate 5, and the adhesive layer 6 may be thermocompression bonded on the lower surface of the first substrate 2.

  As described above, the detachable seal 22 has a structure in which peeling easily occurs between the first base member 2 and the detachable layer 3 having particularly low adhesive strength. However, as indicated by a circle 25, the side surface (end portion) of the removable seal 22 and the first substrate 2 and the removable layer 3 in the vicinity thereof are thermocompression-bonded below the foil layer 24. Thus, in the same manner as the removable seal 21 shown in FIG.

  In the structure shown in FIG. 4, the case where at least the detachable layer 3 and the first base material 2 are thermocompression-bonded using the heat of the step of thermocompressing the foil layer 24 has been described. It is not limited. For example, even when there is no thermocompression bonding step of the foil layer 24, the first and second detachable layers 3 in the region indicated by at least a circle 25 are heated and pressed directly from the upper surface of the detachable layer 3 by a hot press machine. The base material 2 may be thermocompression bonded.

  In the other embodiment, the case where the structure of the removable seal 1 shown in FIG. 1A is used has been described, but the present invention is not limited to this case. For example, even when the structure of the removable seal 10 shown in FIG. 1B is used, the structure of the removable seal shown in FIG. 4A or 4B can be realized. In addition, various modifications can be made without departing from the scope of the present invention.
