Description

  The present invention relates to a method for peeling a sticker such as a seal and a label, a method for recycling a part to be stuck, and an article having a structure capable of easily peeling the sticker.

  In recent years, interest in recycling has been increasing socially, and the need for manufacturing in consideration of recycling is increasing.

  Various molded articles such as home appliances are affixed with paper and plastic seals and labels or the like on which information about the product such as the product serial number, year of manufacture, and precautionary statements is written.

  Generally, when a paper or resin seal or label material is pasted on a metal part of a home appliance housing, it is necessary to peel off the pasted seal or label material in order to recycle the metal part. There is no. This is because when metal scrap is recycled, it is melted at a high temperature of 700 to 1,000 ° C. or higher, so the sealing material / label material made of an organic material instantly becomes a gas such as carbon dioxide gas in the molten metal. It is because it does not remain in.

  However, when similar sealing materials and label materials are affixed to resin parts of home appliance housings, resin recycling (material recycling) usually goes through a melting and pelletizing process at a low temperature of about 150 to 300 ° C. The sealing material / label material remains mixed in the dissolved resin.

  A resin material having a large amount of impurities cannot be used because it hinders pelletization or leads to deterioration of molding quality thereafter. Therefore, it is necessary to peel off the seal material / label material attached to the resin component in order to reuse the resin for material recycling.

  By the way, as shown in Table 1, resin recycling methods are generally classified into material recycling, chemical recycling, and thermal recycling.

  In thermal recycling, which recovers thermal energy by burning it as a fuel, even if the sealing materials and label materials mentioned above are mixed, there is no major problem. Neither recycling nor European WEEE directives are considered as recycling. Therefore, when the recycling rate is calculated by the following formula 1, the weight of the resin part including the sealing material / label material cannot be included in the weight of the molecule in the formula.

  On the other hand, chemical recycling can include the weight in the numerator of the recycling rate calculation formula. However, as with material recycling, impurities mixed into the resin material have a significant effect on the quality of recycled materials. Label material should be avoided.

  In both the Home Appliance Recycling Law and the WEEE Directive, the responsibility for achieving the recycling rate determined for each product type is imposed on the manufacturer, so material and chemical recycling are considered preferable to thermal recycling.

  From the above, when the molded product is made of plastic, if the patch is affixed, the molded product cannot be material-chemically recycled. Therefore, the patch must be peeled off. However, the adhesive usually has a large adhesive strength so that it is not easily peeled off from the molded product, and it takes time and effort to peel it off.

  In the following, recycling refers to material recycling or chemical recycling.

Currently, recycling is performed by scraping or cutting out the part where the sticking of the molded product is pasted, and a structure that makes it easy to cut out has been devised (for example, Patent Document 1 and Patents). Reference 2).
JP 2004-147842 A JP 2003-140555 A

  However, in the conventional structure, the cut base material cannot be recycled. In addition, there is a problem that it takes time to cut out the base material.

  In view of the above-mentioned conventional problems, the present invention can easily peel off a patch, can improve the recycling rate and recycling efficiency, and has a product attached with a seal, a label, and a nameplate, and the peeling of the patch. It aims to provide a method.

  The method for peeling off a patch of the first invention of the present application is a method of destroying a weak body part provided in a partial region including at least one of a plurality of corners of the patch in a part to be stuck to which a patch is stuck. A step of separating the partial region from the part to be pasted by breaking the weak body portion, a step of grasping the separated partial region with the attached material attached thereto, and pulling the grasped partial region And the step of peeling the patch from the part to be bonded.

  By such a method, the partial area is separated from the part to be pasted by breaking the weak body part, and the separated part area is used as a grip allowance while the sticking object is attached, so that the sticking can be easily performed. Can be peeled off.

  It is desirable to recycle the part to be pasted after the patch has been stripped by the stripping method of the patch of the first invention of the present application.

  An article having a patch of the second invention of the present application is an article having a patch having an adhesive layer formed on a surface to be stuck to a part to be stuck, and a part to be stuck to which the sticking is stuck. A weak part having a weak mechanical strength is provided in a partial region of the part to be pasted including at least one of a plurality of corners of the object as compared with other parts of the part to be pasted. It is characterized by.

  With such a configuration, the partial area is separated from the part to be pasted by the destruction of the weak body part, and the separated part area is used as a grip allowance while the sticking object is attached, thereby easily attaching the sticking object. Can be peeled off.

  An article having the patch of the third invention of the present application is a patch having an adhesive layer formed on a base material, a part to be pasted to which the patch is stuck, and at least one or more parts to be combined with the part to be stuck In an article having a part, the patch has a region where both surfaces do not have adhesive strength, and the adhesive formed has no adhesive strength in a gap formed between the part to be pasted and the part. A region is inserted.

  With such a configuration, when recycling the article, by disassembling the part to be pasted and the part, a part of the pasted material sandwiched in the gap appears, and it is easy to use that part as a grip allowance. It becomes possible to peel off the patch.

  An article having a patch of the fourth invention of the present application is a patch having an adhesive layer formed on a base material, a part to be pasted to which the patch is stuck, and at least one or more parts to be combined with the part to be stuck In an article having a component, the adhesive layer formed on the patch is composed of at least two types of adhesive layers having different adhesive strengths, and a gap formed between the component to be bonded and the component A region where an adhesive layer having a weak adhesive force is formed is inserted.

  With such a configuration, when recycling the article, by disassembling the part to be pasted and the part, a part of the pasted material sandwiched in the gap appears, and it is easy to use that part as a grip allowance. It becomes possible to peel off the patch.

  In the article having the patch of the third and fourth inventions of the present application, preferably, the gap between the gaps in the area where the patch is inserted is the gap between the areas where the patch is not inserted. It is desirable that it is wider than the interval.

  A seal 2 is affixed to the part 1 to be adhered, and perforations 3 are formed around the four corners, and a thin portion 4 is formed inside thereof to form a weak body portion (partial region) 5.

  By providing the perforations 3 in all four corners, when sticking the seal 2 to the part 1 to be stuck, it can be used as a mark of the sticking position, and it is possible to prevent deviation of the seal position, but it is necessary to provide in all four corners It may be provided only at one place or along the side. Moreover, although the weak body part 5 is formed using both the perforation 3 and the thin part 4, only either one may be sufficient.

  In the present embodiment, the shape of the seal 2 is generally rectangular, but other shapes may be used, and the perforation 3 and the thin wall portion 4 at that time are provided around the periphery thereof as shown in FIG. By providing in the part, the same effect as this embodiment can be obtained.

  FIG. 4 is a flowchart showing a method for peeling a patch in the present embodiment.

  First, the weak body part 5 is destroyed, and the weak body part 5 is separated from the part 1 to be pasted in a state where a part of the seal 2 is attached to the weak body part 5. Next, the weak part 5 to which a part of the seal 2 is attached is grasped and pulled to peel off the seal 2.

  In this embodiment, the weak body portion 5 is formed by the perforation 3 and the thin portion 4 and is punched to obtain a grip allowance. However, as shown in FIG. The eye 3 may be formed, and the seal 2 may be stuck on the perforation 3.

FIG. 6 is a perspective view of an article having a patch in the second embodiment of the present invention.

  A part of the seal 2 is pasted on the part 1 to be pasted, and the remaining part is inserted into a gap formed by the part 1 to be pasted and the part 6 adjacent to the part 1 to be pasted.

  As shown in FIG. 7, the seal 2 includes a base material 7 and an adhesive layer 8, and the adhesive layer 8 is formed on a part of one side of the base material 7.

  8 is a cross-sectional view of the article having the patch shown in FIG. 6, and FIG. 9 is a top view excluding the seal 2. As shown in FIG.

  The part to be adhered 1 and the part 6 are close to each other, and the gap is not conspicuous. However, the part into which the seal 2 is inserted is provided with a recess in the part to be adhered 1, as shown in FIG. By combining with the component 6, a portion where the interval between the component 1 to be bonded 1 and the component 6 is wide is formed as the seal insertion opening 9. By taking such a configuration, it is possible to prevent an assembly failure of the part 1 and the part 6 due to the thickness of the seal 2.

  In the second embodiment, in order to form the seal insertion port 9, a concave portion is provided in the part 1 to be stuck, but it may be provided in the part 6 or in both, When provided, it is necessary to adjust the positions of the recesses of both parts, which is not preferable.

  FIG. 10 is a flowchart of the sticking method for a sticking material according to Embodiment 1 of the present invention.

  First, the part to be pasted 1 and the part 6 are assembled to form the seal insertion port 9. Next, the part of the seal 2 where the adhesive layer 8 is formed is pasted near the seal insertion port 9 of the part 1 to be pasted, and finally the part where the adhesive layer 8 is not formed is inserted.

  Since the adhesive layer 8 is not formed on the back surface of the insertion portion of the seal 2, the seal 2 adheres to the side surface of the part 1 to be pasted that forms the seal insertion port 9 when inserted into the seal insertion port 9. This can be prevented, and insertion into the seal insertion port 9 can be easily performed.

  As shown in FIG. 11, the seal 2 may be composed of a base material 7, an adhesive layer 8, and a non-adhesive layer 10, and the adhesive layer 8 and the non-adhesive layer 10 may be formed on one entire surface of the base material 7.

  Moreover, you may form an easily peelable adhesive layer instead of the non-adhesive layer 10, and the sticking method of the sticking thing in that case becomes like the flowchart shown in FIG.

  First, the part where the adhesive layer 8 of the seal 2 is formed is affixed to the side of the concave portion of the part 1 to be pasted, and then the part where the seal 2 is bent to form the easily peelable adhesive layer is the part 1 to be pasted. The seal 2 is held in a folded state. Finally, the part 6 is assembled to the part 1 to be adhered to which the seal 2 is adhered.

  In this case, by providing a concave portion in the part 1 to be pasted, it becomes a mark of the sticking position of the seal 2 and the positional deviation of the seal 2 can be reduced.

  The portion of the seal 2 on which the easily peelable adhesive layer is formed is affixed to the side surface of the component 1 to be adhered, the seal 2 is bent, and the portion on which the adhesive layer 8 is formed is affixed to the surface of the component 1 to be adhered. Finally, a step of assembling the part 6 to the part 1 to be pasted with the seal 2 pasted may be taken.

  However, in the case where the length of the seal 2 is set to such a length that the portion to be gripped comes out to the back side of the part 1 to be adhered, it is not necessary to dare to make the easily peelable adhesive layer easily peelable. The seal can be peeled off by using the part on the back side of the part as a grip.

  Also, if the seal is on the back side of the part, disassemble the product by making the seal width of that part wider than the length of the widened part of the interval between the parts where the seal is inserted. Otherwise, the seal cannot be easily peeled off, and the product user can be prevented from peeling off the seal. At this time, if the seal width of the part sandwiched between the parts is narrowed and the seal width of the part that is exposed on the back of the part is widened, the area that widens the space between the parts can be narrowed. The gap can be made less noticeable. FIG. 13 is an example of a seal having such a feature, and FIGS. 14A and 14B are a top view and a front view of an article having a patch using this seal, respectively.

  Further, in this embodiment, the part 1 and the part 6 are adjacent to each other, and a part of the seal 2 is inserted between them. As shown in FIG. It may be inserted between the other parts 11.

  In addition, in this Embodiment, although the seal | sticker 2 is carrying out the substantially rectangular shape, it may take another shape.

  In the present embodiment, the sticker is an example of a sticker, but any sticker may be used as long as it is affixed to a product, such as a label or a nameplate, and the material thereof may be paper, plastic, metal, or These composites may also be used.
