Summary of the Invention
Problems to be Solved by the Invention
[0004] It is conceivable to send a qualification certificate such as a health insurance society using a pressure-bonded postcard. However, with the pressure-bonded postcards described in prior documents and the like, there is a risk that the page corresponding to the qualification certificate will be torn when opened. This problem is common to other pressure-bonded documents such as pressure-bonded envelopes as well as pressure-bonded postcards.
[0005] Therefore, an object of the present disclosure is to provide a pressure-bonded document and a method for manufacturing the pressure-bonded document that can prevent tearing when opening a page that requires protection, such as a qualification certificate.
Means for Solving the Problems
[0006] To achieve the above object, the pressure-bonded document according to the present disclosure A plurality of pages are continuously formed on the front and back surfaces of a single piece of paper The boundary lines between the plurality of pages are used as fold lines, and adjacent pages are stacked to form a document for mailing. In two of the aforementioned pages stacked on top of each other, one page is a page to be protected, and the other page is a protected page. A transparent film layer is formed on the page to be protected, a pseudo-adhesive layer is formed on the protective page, and the page to be protected and the protective page are laminated with the transparent film layer and the pseudo-adhesive layer stacked on top of each other. The tear strength of the transparent film layer is greater than the tear strength of the pseudo-adhesive layer. The page to be protected and the protective page are pressed together by the pseudo-adhesive layer. It is a pressure-sealed document.
[0007] The method for manufacturing a crimped document in this disclosure is: Including a paper folding process and a crimping process, The aforementioned paper folding process is as follows: A single sheet of paper with multiple pages formed consecutively on its front and back surfaces, The process involves folding the pages by using the boundary lines between the multiple pages as fold lines, and stacking adjacent pages together. In two of the aforementioned pages stacked on top of each other, one page is a page to be protected, and the other page is a protected page. The crimping process is as follows: Using a resin tape in which a transparent film layer and a pseudo-adhesive layer are laminated, The process involves placing the resin tape between the page to be protected and the protective page, with the transparent film layer positioned on top of the page to be protected and the pseudo-adhesive layer positioned on top of the protective page, and then laminating and pressing the page to be protected and the protective page together in this state. The tear strength of the transparent film layer is greater than the tear strength of the pseudo-adhesive layer. This is a method for manufacturing pressure-sensitive paper documents. [Effects of the Invention]
[0008] According to this disclosure, it is possible to prevent tearing of pages that require protection, such as certificates of qualification, when opening the package. [Brief explanation of the drawing]
[0009] [Figure 1] Figure 1 is a cross-sectional view showing an example of the structure of the crimped document of this disclosure. [Figure 2] Figure 2 is a diagram showing an example of the configuration of the notch in the crimped document shown in Figure 1. [Figure 3] Figure 3 is an explanatory diagram showing an example of opening the crimped document shown in Figure 1. [Figure 4] Figure 4 is an explanatory diagram showing an example of resin tape. [Figure 5] Figure 5 is a cross-sectional view showing the structure of a comparative example of a crimped document. [Figure 6] Figure 6 is an explanatory diagram showing an example of a crimped document. [Modes for carrying out the invention]
[0010] In the pressure-sealed document of this disclosure, the protective page may have a notch, and when the page to be protected and the protective page are stacked, the page to be protected is exposed through the notch, and it may be possible to open the stacked document by peeling the transparent film layer and the pseudo-adhesive layer from the notch. In this embodiment, the exposure of the page to be protected at the notch may be to the outside via either the transparent film layer and the pseudo-adhesive layer, or both, or it may be to the outside directly without going through the transparent film layer and the pseudo-adhesive layer.
[0011] In the present disclosure, the forming material of the transparent film layer is not particularly limited, and examples thereof include polyester. Examples of the polyester include polyethylene terephthalate (PET). Examples of the forming material of the pseudo-adhesive layer include polyolefin. Examples of the polyolefin include polyethylene, polypropylene, and mixed resins thereof.
[0012] In the pressure-bonded document and the method for manufacturing the pressure-bonded document of the present disclosure, the folding of the paper piece is not particularly limited, and examples thereof include double folding (V-shaped) or triple folding (Z-shaped).
[0013] The size of the pressure-bonded document of the present disclosure is not particularly limited, and for example, it is the postcard size. In the case of the postcard size, the pressure-bonded document of the present disclosure can be used as a pressure-bonded postcard. Note that the form of the pressure-bonded document of the present disclosure is not limited to the pressure-bonded postcard, and for example, it may be a pressure-bonded envelope or the like, and may also be for sending by mail or home delivery.
[0014] In the pressure-bonded document and the method for manufacturing the pressure-bonded document of the present disclosure, for example, the protection page may be in a form in which information related to qualification confirmation is described. Examples of the qualification confirmation include a health insurance qualification confirmation document. According to this aspect, the pressure-bonded document of the present disclosure can be used for sending qualification confirmation documents. Note that the use of the present disclosure is not limited thereto, and it can also be used for sending other items such as cards.
[0015] The method for manufacturing the pressure-bonded document of the present disclosure further includes a notch forming step. The notch forming step is a step of cutting off a part of the protection page of the paper piece to form a notch, and in a state where the protected page and the protection page are laminated, the notch may be formed such that the protected page is exposed from the notch. In this aspect, either or both of the protective film layer and the pseudo-adhesive layer may be exposed.
[0016] In the crimped document and method for manufacturing the crimped document of this disclosure, the tear strength of the transparent film layer is greater than the tear strength of the pseudo-adhesive layer. Due to this relationship of tear strength, in the crimped document of this disclosure, tearing of the protected page is prevented when the protected page is peeled off and opened. The combination of tear strengths is not particularly limited as long as it prevents tearing of the protected page when opened, for example, the transparent film layer may be the polyester layer (e.g., PET layer) and the pseudo-adhesive device may be polyolefin (e.g., polyethylene, polypropylene, or a mixture thereof). The tear strength can be measured by any method.
[0017] Next, embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments. In the following drawings, the same parts are denoted by the same reference numerals. Furthermore, unless otherwise specified, the descriptions of each embodiment can be used interchangeably with those of the others, and unless otherwise specified, the configurations of each embodiment can be combined.
[0018] Figure 1 shows an example of the crimped document of this disclosure. Figure 1 is a cross-sectional view showing the folded structure of the crimped document of this example.
[0019] As shown in Figure 1, the pressure-sensitive document in this example consists of a single sheet of paper 1, which is composed of three pages: page 1a, page 1b, and page 1c. The paper is folded into three sections (Z-shape) along the fold lines between adjacent pages. Page 1b is the page to be protected, and page 1c is the protective page. A transparent film layer 2a is formed on the lower inner surface of page 1b, and a pseudo-resin layer 2b is formed on the upper inner surface of page 1c. A notch 3 is formed in page 1c, and a portion of page 1b, the page to be protected, is exposed to the outside via the transparent film layer 2a and the pseudo-adhesive layer 2b. Furthermore, a transparent film layer 2a is formed on the lower inner surface of page 1a, and a pseudo-adhesive layer 2b is formed on the upper inner surface of page 1b. The pressure-sensitive document in this example is formed into a single document (sheet) by being pressure-sealed in a tri-fold state, with the pseudo-adhesive layer 2b adhering the sections together.
[0020] Figure 2 is a magnified view of the notch 3 of the crimped document 1 in this example. Figure 2(A) shows the state before opening, and Figure 2(B) shows the state after opening. As shown in Figure 2(A), the lower corner of page 1c, which is the protective page, is cut out in the notch 3, and as a result, the lower corner of page 1b, which is the page to be protected, is exposed to the outside through the transparent film layer 2a and the pseudo-film layer 2b. As shown in Figure 2(B), when opening, the notch 3 can be peeled off with a finger to separate page 1b, which is the page to be protected, from page 1c, which is the protective page. Although not shown, after separating pages 1b and 1c, pages 1a and 1b can also be opened by peeling off their edges. Figure 3 is a diagram illustrating how pages 1b and 1c, and pages 1a and 1b are opened.
[0021] Figure 5 shows a cross-sectional view of a pressure-sensitive adhesive document with a different configuration from that of the present disclosure as a comparative example. In the pressure-sensitive adhesive document of this comparative example, a pseudo-adhesive layer 2b is formed on the lower inner surface of page 1b, which is the page to be protected, and a transparent film layer 2a is formed on the upper inner surface of page 1c, which is the protective page, and there is no cutout in page 1c. Other than these, the configuration is the same as that of the pressure-sensitive adhesive document of the present example. In the pressure-sensitive adhesive document of this comparative example, if you try to separate page 1b, which is the page to be protected, from page 1c, which is the protective page, page 1b will tear, and it cannot be used as a pressure-sensitive adhesive document to protect, for example, a certificate of qualification.
[0022] The pressure-sealed document in this example can be manufactured using a dedicated machine for manufacturing pressure-sealed documents. An example of such a machine is the JEMITS8800 (product name) from Kyokuetsu Corporation. The dedicated machine can manufacture pressure-sealed documents of a predetermined standard by supplying paper pieces to be printed and folded, and a special pressure-sealing tape. An example of the pressure-sealing tape is shown in Figure 4. As shown in Figure 4, the pressure-sealing tape 2 is a tape in which a transparent film layer 2a and a pseudo-adhesive layer 2b are laminated. When this pressure-sealing tape is set in the dedicated machine as shown in Figure 1, the folding of the paper pieces and the supply of the pressure-sealing tape are performed automatically. Furthermore, when forming a notch in the protective page 1c, a paper piece with the lower corner of the protective page 1c cut out in advance should be prepared, and this paper piece should be supplied to the dedicated machine for folding and pressure sealing. The notch in the protective page 1c can be formed by processing the paper piece using a notch-making die.
[0023] Figure 6 shows an example of a certificate of eligibility using a pressure-sealed postcard as the pressure-sealed document in this example. As shown in Figure 6(A), on the front side, the left page 1a is the address side of the postcard, the middle page 1b is the page to be protected, and the right page 1c is the protective page, and the right page 1c has been treated to prevent it from being see-through. The middle page 1b, the protected page, has the information of the "Health Insurance Eligibility Confirmation Certificate" printed on it. Also, as shown in Figure 6(B), on the back side, the right page 1a is the pressure-sealed side and therefore has no printing on it, the middle page 1b corresponds to the back of the protected page and has the information related to the eligibility confirmation certificate printed on it, and the left page 1c has no printing on it. Although not shown, a transparent resin layer 2a and a pseudo-adhesive layer 2b are formed as needed on the inner surface of pages 1a, 1b and 1c, as shown in Figure 1. Also, in Figure 6, a triangular cutout is formed at the lower corner of page 1c.
[0024] Although the present disclosure has been described above with reference to embodiments, the present disclosure is not limited to the embodiments described above. Various modifications to the structure and details of the present disclosure are possible, as can be understood by those skilled in the art within the scope of the present disclosure. Furthermore, each embodiment can be combined with other embodiments as appropriate. [Industrial applicability]
