Description

1. State of the art

[0001] The present invention relates to embeddable peelable wireless information carrier plates, and in particular to an embeddable peelable wireless information carrier plate for use in an electromagnetic induction cover insert and to a cover insert containing an embeddable peelable wireless information carrier plate.2. Background of the invention

[0002] A traditional method for ensuring product traceability involves attaching a data tag (usually an RFID tag) capable of recording and reading information to the product packaging. The data tag stores product data, such as the product model number, production history, inventory data, and logistics and transportation data. For example, prior art includes attaching the data tag directly to the neck of the product container or gluing the data tag directly to the middle of the product container.

[0003] Typically, an RFID tag contains an antenna for receiving / transmitting signals and a chip for processing RF signals. The RFID tag is located on the outer surface of the container and is read by a reader to manage and monitor product production history, inventory, and logistics / transportation status.

[0004] Conventional electromagnetic induction lid liners have a layer of aluminum foil and a bottom layer. Using electromagnetic induction, the aluminum foil layer can be heated to melt the bottom layer when it comes into contact with the container mouth, allowing the bottom layer to adhere and thereby seal the container mouth.

[0005] To prevent unauthorized access, some electromagnetic induction lid inserts have an information layer inside. The information layer contains an RF chip and an RF antenna. The RF chip stores various product-related information, such as production and transportation information, to facilitate the prevention and tracking of unauthorized access. DISCLOSURE OF THE INVENTION

[0006] However, prior art teaches that information labels are attached directly to the neck of a product container or that they are glued directly to the middle of a product container. This allows dishonest users to easily remove or peel off the information label and reuse it. Some dishonest users even remove or peel off the information label and then attach or glue it to the container of another product for reuse. This makes the information label vulnerable to counterfeiting. Furthermore, buyers or sellers suffer losses when the reuse of the information label results in a higher purchase price or a lower sales price.Last but not least, the distance that wireless signals can travel is significantly reduced because wireless signals are absorbed by the liquid contents in the container when the information tag is too close to the liquid contents.

[0007] When an information tag (RFID tag) is embedded in the lid liner, peeling the lid liner will cause the information tag to peel off or be destroyed, preventing counterfeiting. Conventional lid liners contain a layer of aluminum foil. Therefore, during the electromagnetic induction heating process, heat is transferred not only to the container's sealing area but also to other areas (such as the aluminum foil layer) of the electromagnetic induction lid liner, resulting in energy loss. Furthermore, each time the sealing layer is heated, the heat releases an unpleasant odor into the container's contents. Furthermore, excessive use of aluminum foil is harmful to the environment.

[0008] Conventional electromagnetic induction cover inserts, each of which contains an information layer, have the following shortcomings: (1) the self-sufficiency of the information layer not only leads to the inevitable excessive thickness of the electromagnetic induction cover insert, but also to unnecessary losses of materials, energy and labor; and (2) the aluminum foil layer is formed as a single unit, thus interfering with the information layer and greatly reducing the wireless information transmission performance.

[0009] Therefore, it is extremely important to solve the problems arising from the use of information labels in lid liners and effectively reduce the amount of aluminum foil used in lid liners.

[0010] The advantages of the invention are described below. The embedded peelable wireless information carrier plate, including an information area (RFID tag), is intended for use in the manufacture of a lid liner to effectively reduce the required amount of aluminum foil and reduce energy consumption. That is, the embedded peelable wireless information carrier plate according to the invention enhances the wireless information transmission function, reduces unnecessary material loss, reduces energy consumption, eliminates unnecessary labor losses, eliminates metal / liquid interaction, improves production efficiency, demonstrates high communication performance, significantly increases communication distances, significantly accelerates the development of automation, digitalization and intellectualization of factories, warehouses, logistics, retail and remote control of POS (point of sale).In a specific embodiment, the inventive embedded peelable wireless data carrier includes a battery for power supply according to a predetermined schedule, regularly records temperature and position parameters, and effectively controls cold chain logistics. The inventive embedded peelable wireless data carrier can be integrated into a lid insert, simplifying and facilitating the production of various lid inserts, particularly electromagnetic induction lid inserts.

[0011] Therefore, the objective of the invention is to create an embedded peelable wireless information carrier plate comprising: a base membrane; an information heating layer containing an information region and an electromagnetic induction heating ring; and a first adhesive layer located between the base membrane and the information heating layer, wherein the information region has an antenna and a microcircuit electrically connected to each other, and the electromagnetic induction heating ring, in views from an angle viewed from above, surrounds the information region.

[0012] In one embodiment, the embedded peelable wireless information carrier plate further comprises a protective layer and a second adhesive layer, wherein the protective layer is located on the side of the information heating layer and faces away from the main membrane, and the second adhesive layer is located between the information heating layer and the protective layer.

[0013] In one embodiment, the electromagnetic induction heating ring is separated from the data region by a gap. In a preferred embodiment, there is a full-bore gap between the electromagnetic induction heating ring and the data region.

[0014] In one embodiment, the protective layer is made of at least one material selected from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyamide (PA), polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), polyethylene naphthalate (PEN) and polyimide (PI), and has a thickness of 12 μm ~ 100 μm.

[0015] In one embodiment, the main membrane is made of at least one material selected from the group consisting of polyimide (PI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polycarbonate (PC), polypropylene (PP) and polyethylene (PE), and has a thickness of 20 μm ~ 150 μm.

[0016] In one embodiment, the cutting line is defined on the inner side of the inner rim of the electromagnetic induction heating ring, has a plurality of breaking points, is located between the information region and the electromagnetic induction heating ring and surrounds the information region.

[0017] In one embodiment, the electromagnetic induction heating ring is made of aluminum, copper, gold, silver, or tin and has a thickness of 6 μm ~ 40 μm.

[0018] In one embodiment, the first adhesive layer is made of a laminating adhesive and has a thickness of 0.5 μm ~ 7 μm.

[0019] In one embodiment, the second adhesive layer is made of a laminating adhesive and has a thickness of 0.5 μm ~ 7 μm.

[0020] In one embodiment, the gap is the distance between the outermost edge of the information region and the innermost edge of the electromagnetic induction heating ring and is 0.1 mm ~ 3 mm.

[0021] In one embodiment, the information heating layer comprises at least one physical connecting bridge connecting the information region and the electromagnetic induction heating ring.

[0022] The cover insert in one aspect of the invention comprises an embedded peelable wireless information carrier plate.

[0023] In one embodiment, the cover insert further comprises a top layer laminated on top of the embedded peelable wireless information carrier plate, wherein the top layer is made of at least one material selected from the group consisting of paper, PE, PP, PET, PA, PEN, polyimide (PI), expandable polyethylene (EPE), expandable polypropylene (EPP), expandable polystyrene (EPS), wax, varnish, silicone oil and polyurethane, and has a thickness of 12 μm ~ 3 mm.

[0024] In one embodiment, the cover insert further comprises a bottom layer laminated from below onto the embedded peelable wireless information carrier plate, wherein the bottom layer is made of at least one material selected from the group consisting of paper, PE, PP, PET, polyamide (PA), polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), ethylene vinyl acetate copolymer (EVA), polyisobutylene (PIB), ethylene acrylic acid copolymer (EAA), ethylene ethyl acrylate (EEA), ethylene methyl methacrylate copolymer (EMMA), ethylene methyl acrylate copolymer (EMAC), ethylene methacrylic acid copolymer (EMAA), polyacrylate, polyacetate and polyurethane, and has a thickness of 3 μm ~ 120 μm.

[0025] Thus, the object of the invention is to create an embedded peelable wireless information carrier plate, in particular, an embedded peelable wireless information carrier plate capable of heating a lid insert by electromagnetic induction. The embedded peelable wireless information carrier plate can be used with various lid inserts, improves the wireless information transmission function, reduces material waste, reduces energy consumption, eliminates unnecessary labor costs, eliminates metal / liquid interaction, improves production efficiency, demonstrates high communication performance, significantly increases communication distances; significantly improves the development of automation, digitalization and intellectualization in factories, warehouses, logistics, retail, stores and remote POS (point of sale) management.

[0034] The invention is illustrated below with specific embodiments. Those skilled in the art will recognize other advantages and effects of the invention. The invention may be implemented or applied in accordance with any other embodiments. The details presented herein may be changed or modified from various perspectives and for various applications within the scope of the invention.

[0035] Unless otherwise specified, the meaning of the expression "A~B" used in this document and in the appended claims includes "more than A and less than B." For example, the meaning of the expression "10~40% m / m" includes "more than 10% m / m and less than 40% m / m."

[0036] [First Embodiment]<Embeddable Peelable Wireless Information Carrier Plate>FIG. 1 is a sectional view of an embeddable peelable wireless information carrier plate 100 according to an embodiment of the invention. As shown in FIG. 1, the embeddable peelable wireless information carrier plate 100 in the embodiment of the invention comprises a base membrane 1, a first adhesive layer 2, and a data heating layer 3. The first adhesive layer 2 is disposed between the base membrane 1 and the data heating layer 3 to connect the base membrane 1 and the data heating layer 3.

[0037] <<Base membrane>>The base membrane 1 is an initial layer for use in the production of an embedded peelable wireless information carrier plate. In a specific embodiment, the base membrane 1 is made of at least one material selected from the group consisting of PI, PEN, PET, PC, PP and PE. In a preferred embodiment, the base membrane 1 has a thickness of 20 μm ~ 150 μm to ensure maximum longitudinal tensile strength. As shown in FIG. 1, the base membrane 1 has a lower surface connected to the first adhesive layer 2, and an upper surface serving as a printing surface for printing various patterns.

[0038] <<First Adhesive Layer>>The first adhesive layer is designed to bond the base membrane and the data-heating layer to each other. In a specific embodiment, the sole purpose of the first adhesive layer 2 is to bond the base membrane 1 and the data-heating layer 3 to each other, wherein the first adhesive layer 2 is, for example, made of a laminating adhesive. The first adhesive layer 2 has a thickness of 0.5 μm ~ 7 μm, so that the peel strength between the two bonded layers is greater than 4 N / 15 mm.

[0039] <<Information-heating layer>>According to the invention, the information-heating layer 3 comprises an information region 31 and an electromagnetic induction heating ring 32. The information region 31 is capable of reading, writing and transmitting wireless information to ensure product traceability. The information region 31 has an antenna 312 and a microcircuit 311 electrically connected to each other. The electromagnetic induction heating ring 32 generates heat due to the electromagnetic induction of an electromagnetic field generated by an electromagnetic induction sealer; wherein the sealing layer of the lid liner is heated, melted and hermetically attached to the container neck, thereby forming an electromagnetic induction lid liner for sealing the container neck.The embedded peelable wireless information carrier plate according to the invention enables heat generation primarily by the electromagnetic induction heating ring 32, allowing a small amount of heat to be transferred exclusively through at least one physical connecting bridge 33 between the antenna 312 and the electromagnetic induction heating ring 32. The physical connecting bridges 33 have a length of 0.1 mm ~ 3 mm and a width of 0.01 mm ~ 5 mm, and the physical connecting bridges 33 can be made of the same material as the antenna 312. In this way, not only is excessive heat used to achieve electromagnetic induction sealing prevented from spreading toward the central region of the cover insert, but energy losses are also reduced.

[0040] FIG. 2A is a top view of the information heating layer according to one embodiment of the invention, and FIG. 2B is a top view of the information heating layer according to another embodiment of the invention. As shown in FIG. 2A or 2B, in the views from the top angle, the electromagnetic induction heating ring 32 surrounds the information region 31. As shown in FIG. 2A, there is a full-bore gap ITV between the electromagnetic induction heating ring 32 and the information region 31, that is, there is no physical connecting component (such as a physical connecting bridge described below) between the electromagnetic induction heating ring 32 and the information region 31.When the ITV gap between the electromagnetic induction heating ring 32 and the information region 31 is filled, the filled ITV gap stops the heat transfer to the information region 31 during the electromagnetic induction heating process, so this embodiment is a preferred embodiment. The ITV gap (defined as the distance between the outermost edge of the information region and the innermost edge of the electromagnetic induction heating ring) is 0.1 mm ~ 3 mm. As shown in FIG. 2B, the electromagnetic induction heating ring 32 and the information region 31 are almost completely separated by the ITV gap. The ITV gap prevents most of the heat from being transferred to the information region 31 during the electromagnetic induction heating process, and the ITV gap (defined as the distance between the outermost edge of the information region and the innermost edge of the electromagnetic induction heating ring) is 0.1 mm ~ 3 mm.At least one physical connecting bridge 33 (two of which are shown in FIG. 2B and FIG. 3B) is located between the antenna 312 and the electromagnetic induction heating ring 32 and has a length of 0.1 mm ~ 3 mm and a width of 0.01 mm ~ 5 mm. In this case, despite the fact that the electromagnetic induction heating ring 32 in the form of a closed ring structure is electrically connected to the information region 31, this does not lead to an excessive reduction in the wireless communication distance. In other words, between the electromagnetic induction heating ring 32 and the information region 31, there may be a full-bore ITV gap, there may be both an ITV gap and a physical connecting bridge 33, or there may not be any gap. For example, a full-bore physical connecting bridge 33 may be implemented between the electromagnetic induction heating ring 32 and the information region 31.

[0041] In a specific embodiment, the electromagnetic induction heating ring 32 is made of a metal, such as aluminum, copper, gold, silver, or tin. In a preferred embodiment, to generate heat under the action of an alternating electromagnetic field and optimize cost efficiency, the electromagnetic induction heating ring 32 is made of aluminum foil and has a thickness of 6 μm to 40 μm.

[0042] The chip 311 has a unique identification code, which is selected to implement the corresponding purpose, for example, a near-field radio frequency identification chip (RFID_NFC), a high-frequency radio frequency identification chip (RFID_HF), a super-high frequency radio frequency identification chip (RFID_UHF), or a super-high frequency radio frequency identification chip (RFID_MW), but the invention is not limited to these embodiments. All of the above-mentioned chips can be coordinated with the antenna 312 to perform the wireless information communication function.

[0043] Antenna 312 generates signals that can be transmitted wirelessly and is made of a metal such as copper, silver, gold, tin or aluminum, but the invention is not limited to these embodiments.

[0044] FIG. 3A is a top view of the information region according to one embodiment of the invention, and FIG. 3B is a top view of the information region according to another embodiment of the invention. FIG. 6 is a sectional view of the embedded peelable wireless information carrier plate according to one embodiment of the invention. Here, FIG. 3A corresponds to the above-mentioned embodiment illustrated in FIG. 2A, with a full-bore ITV gap between the electromagnetic induction heating ring 32 and the information region 31, and FIG. 3B corresponds to the above-mentioned embodiment illustrated in FIG. 2B, in which the electromagnetic induction heating ring 32 and the information region 31 are almost completely separated by the ITV gap. As shown in FIG. 3A or 3B, the information region 31 contains a chip 311 and an antenna 312.The positions of the microcircuit 311 and the antenna 312 relative to each other in section are shown in FIG. 6. As shown in FIG. 6, the microcircuit 311 is covered with a protective adhesive 6 of the microcircuit housing (made, for example, of epoxy resin), and thus the microcircuit 311, as well as the wire leads for connecting the microcircuit 311 and the antenna 312, are protected by the protective adhesive 6 of the microcircuit housing from damage under the action of external forces. When performing the wireless information transmission function, the microcircuit 311 and the antenna 312 can be arranged in accordance with the images in FIG. 3A or 3B and FIG. 6, or in another way in accordance with the RFID frequency range that the user wants to use, but the invention is not limited to these options.

[0045] In another embodiment, illustrated in FIG. 6, the information region 31 further has a battery 313 for supplying the electrical energy required for transmitting information. In a preferred embodiment, the battery 313 is positioned so as not to hide the antenna, and so that the battery 313 does not affect the wireless transmission of the antenna 312. The thickness of the battery 313 is greater or less than the antenna 312, depending on the materials from which the battery is made, the requirements for use, and the permissible space between the container and the lid.That is, when the power supply is started in accordance with the default command from the application software and the reader / writer, the chip 311 for use in wireless information transmission operates smoothly and thus smoothly stores a record of the operating parameters (for example, a temperature parameter and a position parameter) to facilitate efficient logistics management (for example, cold chain logistics), and can be arranged, for example, in accordance with a known volume, size, thickness, or in the manner illustrated in FIG. 6.

[0046] As shown in FIG. 3A or 3B, in another embodiment, the cutting line 321 is defined on the inner side of the inner rim of the electromagnetic induction heating ring 32. In a preferred embodiment, the cutting line 321 has multiple rupture points. That is, the cutting line 321 has at least four rupture points. Despite the high tensile strength of the material of the embedded peelable wireless information carrier plate, the cutting line 321 allows the embedded peelable wireless information carrier plate to be used in connection with certain lid liners, for example, a lid liner, the sealing ring of which remains on the container neck after the user, by grasping a part of the lid liner with his fingers, tears off the middle part of the lid liner. As shown in FIG.3A or 3B, the cutting line 321 is located between the information region 31 (containing the microcircuit 311 and the antenna 312) and the electromagnetic induction heating ring 32 and surrounds the information region.

[0047] Finally, the thickness of the heating layer 3 can be adjusted according to the battery materials, user needs (i.e., the intended lid liner), and the allowable space between the container and the lid. That is, the heating layer has a thickness of 6 μm ~ 2.5 mm when used with a lid liner that contains a battery. If the lid liner does not contain a battery, the heating layer has a thickness of 6 μm ~ 300 μm.

[0048] FIG. 1 shows that the main membrane 1 is located above the information-heating layer 3, however, this sequence can be reversed, and it is also possible that, if necessary, the main membrane 1 is located below the information-heating layer 3.

[0049] [Second Embodiment] Unlike the embeddable peelable wireless information carrier plate 100 in the first embodiment, the embeddable peelable wireless information carrier plate 100' in the second embodiment shown in FIG. 4 further comprises a protective layer 5 and a second adhesive layer 4. The protective layer 5 is located on the side of the information heating layer 3 and faces away from the base membrane 1. The second adhesive layer 4 is located between the information heating layer 3 and the protective layer 5 and is for connecting the information heating layer 3 and the protective layer 5 to each other.

[0050] <<Second adhesive layer>> In a specific embodiment, the only purpose of the second adhesive layer 4 is to connect the information heating layer 3 and the protective layer 5 to each other, and the second adhesive layer 4 is made of, for example, a laminating adhesive, but the invention is not limited to this embodiment. The second adhesive layer 4 has a thickness of 0.5 μm ~ 7 μm, which in the preferred embodiment provides a peel-off strength between the two connected layers of materials of more than 4 N / 15 mm. As shown in FIG. 4, the second adhesive layer 4 extends so as to completely fill the gap between the electromagnetic induction heating ring 32 and the information region 31, which increases the overall structural strength of the embedded peelable wireless information carrier plate 100'.

[0051] <<Protective Layer>>The protective layer 5 in this embodiment will be described below. The protective layer 5 protects the information region 31 (i.e., the chip 311, the antenna 312, and, if necessary, the battery 313), thereby preventing the chip 311 and the battery 313 from being damaged by any external force that may affect the wireless information transmission capability. The protective layer 5 is made of at least one material selected from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyamide (PA), polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), polyethylene naphthalate (PEN), and polyimide (PI). In a preferred embodiment, the protective layer 5 has a thickness of 12 μm ~ 100 μm.

[0052] Either the upper surface or the lower surface of the protective layer 5 serves as the printing surface. Therefore, although FIG. 4 shows that the base membrane 1 is located under the protective layer 5 (with the upper surface of the protective layer 5 serving as the printing surface), this sequence can be reversed if necessary, and it is also possible for the base membrane 1 to be located above the protective layer 5 (with the lower surface of the protective layer 5 serving as the printing surface).

[0053] [Production of Embeddable Peelable Wireless Information Carrier Plate]The roll material for the embeddable peelable wireless information carrier plate related to this embodiment is obtained by performing the following steps described below.

[0054] First, a laminating adhesive (the first adhesive layer) is applied to the laminating surface of the base membrane roll material. This adhesive is then laminated onto the laminating surface of the metal foil roll material to form the roll material of the embedded peelable wireless data carrier plate blank. Next, the metal foil of the roll material of the embedded peelable wireless data carrier plate blank is etching processed and electrically connected to the antenna and the chip through wire bonding. Then, the chip and the wire leads connecting the chip and antenna are packaged using a dispenser and protective adhesive for chip packaging.In this case, an information heating layer is formed on the metal foil, and the roll material of the embedded peelable wireless data carrier blank becomes the roll material of the embedded peelable wireless data carrier blank related to the embodiment. The roll material of the embedded peelable wireless data carrier blank can then be cut as needed to produce the desired embedded peelable wireless data carrier blank.

[0055] The peel strength between two layers of material laminated to each other with laminating adhesive is greater than 4N / 15mm.

[0056] To embed the battery into the data heating layer, the battery plate and the chip can be welded or treated with conductive adhesive and thus electrically connected to each other.

[0057] In another aspect, a roll material for an embedded peelable wireless information carrier plate related to another embodiment is obtained by performing the following steps described below.

[0058] First, a laminating adhesive (first adhesive layer) is applied to the laminating surface of the base membrane roll material. This adhesive is then laminated onto the laminating surface of the metal foil roll material to form the roll material of the embedded peelable wireless data carrier plate blank. Next, the metal foil of the roll material is etched and electrically connected to the antenna and the chip through wire bonding. The chip and the wire leads connecting the chip and antenna are then packaged using a dispenser and protective adhesive for chip packaging.In this case, an information heating layer is formed on the metal foil, and the roll material of the blank of the embedded peelable wireless information carrier plate becomes the roll material of the embedded peelable wireless information carrier plate, related to another embodiment.

[0059] After this, a laminating adhesive (second adhesive layer) is applied to the roll material of the protective layer, which is laminated to the surface of the information heating layer of the roll material of the embeddable peelable wireless information carrier plate related to another embodiment (i.e., to the surface facing away from the base membrane), to obtain a roll material of the embeddable peelable wireless information carrier plate related to another embodiment. After this, the roll material of the blank of the embeddable peelable wireless information carrier plate related to another embodiment can be cut according to needs to produce the desired embeddable peelable wireless information carrier plate.

[0060] The peel strength between two layers of material laminated with a laminating adhesive exceeds 4 N / 15 mm. To embed the battery into the data-heating layer, the battery plate and the chip can be welded or treated with conductive adhesive, thereby electrically connecting them.

[0061] (Manufacturing of a lid liner)The lid liner is made of a roll material of an embeddable peelable wireless information carrier plate according to the invention. FIG. 5 is a sectional view of a lid liner 900 according to one embodiment of the invention. As shown in FIG. 5, the roll material of the embeddable peelable wireless information carrier plate 100, the upper layer 200 and the lower layer 300 in the above-mentioned embodiment are connected together to manufacture the roll material of the lid liner 900. After this, the roll material of the lid liner 900 can be laminated and cut according to needs to manufacture the desired lid liner.

[0062] The top layer 200 is made of at least one material selected from the group consisting of paper, PE, PP, PET, PEN, PA, polyimide (PI), expandable polyethylene (EPE), expandable polypropylene (EPP), expandable polystyrene (EPS), wax, varnish, silicone oil and polyurethane, and has a thickness of 12 μm ~ 3 mm.The bottom layer 300 (an adhesive sealing film or an adhesive sealing film and a reinforcing layer thereon) for use in sealing the container neck is made of at least one material selected from the group consisting of paper, PE, PP, PET, polyamide (PA), polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), ethylene vinyl acetate copolymer (EVA), polyisobutylene (PIB), ethylene acrylic acid copolymer (EAA), ethylene ethyl acrylate (EEA), ethylene methyl methacrylate copolymer (EMMA), ethylene methyl acrylate copolymer (EMAC), ethylene methacrylic acid copolymer (EMMA), polyacrylate, polyacetate and polyurethane, and has a thickness of 3 μm ~ 120 μm.

[0063] Lamination can be achieved by the above-mentioned lamination technology or a conventional adhesion, pressing or coating technology, but the invention is not limited to these embodiments.

[0064] It should be noted that the above description is only a description of a specific embodiment and does not limit the sequence of layer formation steps. The above description is of the manufacturing process of the embedded peelable wireless information carrier plate 100. However, the embedded peelable wireless information carrier plate 100' can not only replace the embedded peelable wireless information carrier plate 100, but also can be replaced by adhesion, bonding, lamination, or bonding.

[0065] The invention is not limited to the embodiments discussed above. Various modifications can be made thereto within the scope of the present invention, as defined by the appended claims. Any embodiment by appropriately combining the technical features disclosed in the various embodiments should be considered as falling within the scope of the invention.
