Description

  The present invention relates to a lid member such as a wet tissue packaging bag that can prevent, for example, drying of a wet tissue, can easily take out the wet tissue, and is reusable.

  In recent years, wet tissues have been used habitually for various purposes including infants and nursing care. A wet tissue packaging bag (package) for storing such a wet tissue is usually made of a synthetic resin material, and an adhesive is applied as a means for blocking the outlet so that the wet tissue is not dried. It is commercially available with a sealing film and a lid made of a synthetic resin material attached for easy removal.

  When using the sealing film coated with the adhesive, once the sealing film is opened and used, the wet tissue outlet is gradually incompletely sealed due to drying or dirt on the adhesive part. The moisture of the wet tissue leaks to the outside through the take-out port, resulting in a problem that the material of the wet tissue is lowered, foreign matters are mixed and unsanitary, and the removal of the wet tissue becomes inconvenient.

  In order to solve this problem, Patent Document 1 discloses a wet tissue bag lid formed of a lid body and a main body provided with locking hooks and latching pieces.

  However, in the case of the wet tissue bag lid, since it is provided in a state firmly fixed to the wet tissue bag using a strong adhesive or the like, it must be discarded together with the wet tissue bag when the wet tissue is used up. There are problems such as waste of resources, environmental pollution, and increase in manufacturing costs.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and is made of a synthetic resin material and is attached to the bottom surface of a lid formed with an opening that allows easy removal of wet tissue. More specifically, a fixed adhesive layer, a tape core, and a desorption adhesive layer are sequentially formed on the bottom surface of the lid, and the adhesive strength of the lid-side adhesive layer is adjusted to that of the adhesive layer on the wet tissue packaging bag side. When the adhesive force was set to be relatively larger than the adhesive force, it was found that the adhesive layer was firmly fixed to the lid and could be detached from the wet tissue packaging bag, and could be reused, thus completing the present invention.

  Accordingly, an object of the present invention is to provide a wet sheet lid member provided with an adhesive layer configured such that the adhesive forces of the double-sided adhesive layers are different.

  Therefore, a wet sheet lid member according to the present invention for achieving the above object includes a wet sheet and a wet sheet attached to a wet sheet package having a wet sheet take-out port from which the wet sheet can be taken out. A lid body having an opening for exposing the wet sheet take-out port at a central portion, and a hinge portion rotatably held on the lid body, wherein the opening is opened by the hinge portion. A lid that can be opened and closed, and a fixed adhesive layer, a tape core, and a desorption adhesive layer are sequentially formed on a bottom surface of the lid body, and the lid body is formed by the removable adhesive with the wet sheet. By being detachably attached to the package, it can be reused in the wet sheet package.

  Further, the adhesive force of the fixed adhesive layer is set to be relatively larger than the adhesive force of the desorption adhesive layer.

  The fixed adhesive layer has an adhesive strength measured by JIS-Z-0237 test method, 180 DegreePeelTest set in the range of 500 g to 1500 g. The measured adhesive strength is set in the range of 50 to 1000 g.

  The fixed adhesive layer may be formed by applying an acrylic resin adhesive to the tape core, and the desorbing adhesive layer may be formed by applying a urethane resin adhesive to the tape core.

  According to the present invention, after the wet sheet is used, only the lid can be removed and attached to other products many times, so that it is possible to reduce the waste of resources and reduce the production cost of the producer. Since it can contribute to the reduction of waste and the amount of waste discharged can be reduced, the effect of environmental conservation can be obtained.

  Further, according to the present invention, it is possible to prevent moisture from leaking through the wet sheet take-out port, and it is possible to expect the effect of preventing the quality of the wet sheet from being deteriorated.

  Furthermore, according to the present invention, when the adhesive surface of the lid becomes dirty and the adhesive strength becomes weak, the adhesive strength is restored by a simple method of removing the stain by wiping with water, so the effect of extending the use period can be expected. . In addition, since sufficient adhesive force can be secured even after repeated use, it can be opened and closed with one hand, so hygiene and efficient care (for caregivers such as infants and the elderly) can be achieved. I can expect.

  FIG. 3 is a bottom perspective view of the wet tissue lid member according to the present invention, and FIG. 4 shows a cross section of the lid mounting surface of the wet tissue packaging bag to which the wet tissue lid member according to the present invention is applied. It is a schematic diagram.

  As shown in FIG. 3, the wet tissue lid member of the present invention has an adhesive layer formed on the bottom surface of the lid body 12, and the adhesive layer is an adhesive layer adhesive on both sides with respect to the tape core 100. The force is configured to be different from each other.

  That is, one surface is firmly fixed to the bottom surface of the lid body 12 of the lid member for wet tissue, and the other surface is attached around the wet tissue outlet of the wet tissue packaging bag 20, but when the wet tissue is used up, it is shown in FIG. Thus, the lid member for wet tissue can be separated from the wet tissue packaging bag 20 and can be reused.

  For this purpose, the fixed adhesive layer 110 attached to the bottom surface of the lid body 12 with the tape core 100 as a reference must be firmly adhered to a wet tissue lid member made of a synthetic resin material. Detachable adhesive layer on the side of the wet tissue packaging bag 20 so that it can withstand the load of the wet tissue packaging bag 20 included and is not detached by tension when the wet tissue packaging bag 20 is separated from the lid member for wet tissue. Compared to 120, it must be configured relatively large. That is, the adhesive force of the fixed adhesive layer 110 is set to be relatively larger than the adhesive force of the desorption adhesive layer 120.

  More specifically, adhesives of different materials are applied to both surfaces of the tape core 100, but the fixed adhesive layer 110 is preferably made of an acrylic resin adhesive, and the desorption adhesive layer 120 is When the wet tissue packaging bag 20 is separated from the wet tissue lid member, it is preferably made of a urethane resin adhesive so that it can be completely removed without leaving an adhesive on the surface of the wet tissue packaging bag 20. .

  For the tape core 100, a polyethylene film or the like can be generally used, and the thickness can be adjusted to about 0.02 mm to 0.1 mm. The volume of the wet tissue packaging bag 20 and the weight of the wet tissue contained therein The total thickness of the fixed adhesive layer 110, the tape core 100, and the desorption adhesive layer 120 may be adjusted to a range of 0.05 mm to 1.2 mm. .

  As an example, the adhesive strength of each pressure-sensitive adhesive layer bonded to the wet tissue lid member of the present invention was measured by 180 DegreePeelTest using JIS-Z-0237 test method and Bigup meta. When the thickness of the tape core 100 and the desorption adhesive layer 120 is 0.0125 mm, the adhesive force of the fixed adhesive layer 110 is 1100 g, and the adhesion force of the desorption adhesive layer 120 is 65 g. Can do. As another example, when the total thickness of the fixed adhesive layer 110, the tape core 100, and the desorption adhesive layer 120 is 1.0 mm, the adhesive force of the fixed adhesive layer 110 is 600 g, and the desorption adhesive layer 120. The adhesive strength can be configured to be 110 g. As yet another example, when the total thickness of the fixed adhesive layer 110, the tape core 100, and the desorption adhesive layer 120 is 0.07 mm, the adhesive force of the fixed adhesive layer 110 is 1200 g, and the desorption adhesive layer. The adhesive strength of 120 can be configured to be 800 g.

The measurement standards of the fixed adhesive layer 110, the tape core 100, and the desorption adhesive layer 120 applied to the wet tissue lid member of the present invention are shown in Table 1 below.

  It was confirmed that the fixed adhesive layer 110, the tape core 100, and the desorption adhesive layer 120 formed on the bottom surface of the wet tissue lid member of the present invention sufficiently satisfy the above-described conditions.

  On the other hand, the lid member for wet tissue of the present invention has a pressure-sensitive adhesive layer set to have different adhesive forces on both sides as described above, a fixed pressure-sensitive adhesive layer 110 on the bottom surface, a tape core 100, a desorption pressure-sensitive adhesive layer 120, In particular, the desorption adhesive layer 120 adhered to the wet tissue packaging bag 20 can be desorbed, and when the wet tissue is used up, it is easily separated from the wet tissue packaging bag 20. Can be reused.

  In particular, since the desorption adhesive layer 120 is processed with a urethane resin adhesive, the desorption adhesive layer 120 can be detached from the wet tissue packaging bag 20 and reused any number of times. Since the adhesive does not move toward the wet tissue packaging bag 20 even if it is removed, it does not leave any traces or contamination of the adhesive, and even if the adhesive strength becomes weak after several reuses, the dirt can be removed by wiping with water. Since the adhesive strength is restored, it can be reused.
