Description
本発明は美術品や装飾品を入れて飾るための密閉式額縁や飾り箱の密閉構造に関するものである。 The present invention relates to a hermetically sealed picture frame and a sealed structure for a decorative box for displaying artworks and ornaments.
従来、密閉式額縁や飾り箱の密閉構造は保護板の端の部分に密閉構造を維持するためのシートを接着剤で固定する方法が採用されてきた。しかし、保護板とシートの接着面積が充分に確保出来ず接着強度が弱く、また、接着に時間が掛かる上、製作にばらつきが多く接着部の綺麗さや製品としての安定度、信頼性に欠ける。また、難接着性素材例えば、アクリル板とポリエチレンやポリプロピレンシート等は接着剤では接合できないという問題点があった。（例えば、特願２０００−３０２９０６、特願２００２−７１０２９、特願２００３−１０２２１１） Conventionally, a method of fixing a sheet for maintaining a sealed structure to an end portion of a protective plate with an adhesive has been adopted for a sealed structure of a sealed picture frame or a decorative box. However, a sufficient bonding area between the protective plate and the sheet cannot be ensured, the bonding strength is weak, the bonding takes time, and the production has many variations, and the bonding part is not clean and the product is not stable and reliable. In addition, there is a problem that difficult-to-adhere materials such as acrylic plates and polyethylene or polypropylene sheets cannot be joined with an adhesive. (For example, Japanese Patent Application 2000-302906, Japanese Patent Application 2002-71029, Japanese Patent Application 2003-102211)
従来の密閉式額縁や飾り箱の密閉構造部の保護板と密閉を維持するための密閉シートの接合方法としては接着剤による接合が主として採用されてきた。しかし、この方法では取り扱える保護板やシートの材質が接着可能な材質に限定されていた。すなわち、より接着しやすいナイロンや塩化ビニールシートが使用されてきた、しかし、塩化ビニールでは分解して塩素ガスが発生することやナイロンでは熱に弱い等の理由により密閉材としての使用はできず別の素材で密閉構造部に収める美術品への影響が少ない、ポリエチレンやポリプロピレン等またはポリエチレンやポリプロピレンにナイロンをコーティングした複合材シートが使用されているのが現状である。しかし、近年密閉シートの材質はポリプロピレンやポリエチレンシートの複合材等がより密閉性が好い素材として採用されるように成ってきた。その場合、これらのシート材は熱圧着接合が可能であるが、接着剤による直接接合は非常に困難であるという問題点があった。 As a conventional method of joining a sealing frame for maintaining a hermetic seal with a protective plate of a hermetically sealed picture frame or a sealed structure part of a display box, joining with an adhesive has been mainly employed. However, in this method, the protective plate and sheet that can be handled are limited to materials that can be bonded. In other words, nylon and vinyl chloride sheets that are easier to bond have been used. However, it cannot be used as a sealing material due to the fact that vinyl chloride decomposes and generates chlorine gas, and nylon is vulnerable to heat. In the present situation, polyethylene, polypropylene, or a composite material sheet in which nylon is coated on polyethylene or polypropylene is used. However, in recent years, as a material for the sealing sheet, a composite material of polypropylene or polyethylene sheet has been adopted as a material having better sealing properties. In that case, these sheet materials can be thermocompression bonded, but there is a problem that direct bonding with an adhesive is very difficult.
本発明は、熱圧着接合が可能なポリエチレンまたはポリエチレンとポリプロピレンの複合シートを薄い板状のガラス製またはアクリル製の保護板に充分強度を確保した状態で接合し、しかも仕上げ精度、安定度を維持できる密閉式額縁や飾り箱の密閉構造を提供することを目的としている。 In the present invention, polyethylene or a composite sheet of polyethylene and polypropylene capable of thermocompression bonding is bonded to a thin plate-shaped glass or acrylic protective plate with sufficient strength, and the finishing accuracy and stability are maintained. The purpose is to provide a closed frame and a sealed structure of a display box.
上記目的を達成するために、額縁の枠の前面に着脱自在に嵌め込み、絵画、版画、写真等を保護するための透明な板状の保護板の周囲の端の部分に接着剤を塗布して、ポリエチレンシートにナイロンをコーティングした複合固定シートのナイロン面を接着固定すると共に、この保護板の周囲に固定された複合固定シートのポリエチレンの面に前記絵画、版画、写真等を覆うための密閉シートとしてポリエチレンまたはポリエチレンとポリプロピレンの複合シートのポリエチレン面を熱圧着接合にて取り付け前記額縁の枠に着脱自在に入れられる密閉式額縁の密閉構造とする。 In order to achieve the above-mentioned purpose, it is detachably fitted to the front of the frame of the frame, and an adhesive is applied to the peripheral edge portion of a transparent plate-like protective plate for protecting paintings, prints, photographs, etc. Adhesive fixing the nylon side of the composite fixing sheet in which nylon is coated on the polyethylene sheet, and sealing sheet for covering the painting, print, photograph etc. on the polyethylene side of the composite fixing sheet fixed around the protective plate A polyethylene frame or a polyethylene-polypropylene composite sheet is attached to the polyethylene surface by thermocompression bonding to form a hermetic frame-type sealed structure that can be detachably inserted into the frame of the frame.

図１に示す実施例において、保護板１の端の周囲に密閉シート３を取り付けた密閉構造部に絵画、書、版画等８を収め額縁の枠６に入れて裏蓋７を閉めた状態を示す。In the embodiment shown in FIG. 1, a state in which a picture, a book, a print, etc. 8 are placed in a sealed structure part in which a sealing sheet 3 is attached around the edge of the protective plate 1 and put in a frame 6 of the frame and the back cover 7 is closed. Show.
図２において示される実施例において密閉構造部の詳細について示す。密閉構造部の保護板１の端の部分の周囲に接着剤１３を塗布して、この接着剤１３にポリエチレンシートにナイロンをコーティングした複合固定シート１４のナイロン面を接着固定して、複合固定シートの裏側のポリエチレン面にポリエチレンまたはポリエチレンとポリプロピレンの複合密閉シート３を熱圧着接合して取り付け密閉構造とした場合である。The details of the sealing structure in the embodiment shown in FIG. 2 will be described. An adhesive 13 is applied to the periphery of the end portion of the protective plate 1 of the hermetic structure portion, and the nylon surface of the composite fixing sheet 14 in which nylon is coated on the polyethylene sheet is adhered and fixed to the adhesive 13. This is a case where a polyethylene or polyethylene / polypropylene composite sealing sheet 3 is thermocompression-bonded to the polyethylene surface on the back side to provide a sealed structure.
図３において示される実施例において保護板１７の端に接着剤１３を使用してポリエチレンシートにナイロンをコーティングした固定シート２４を取り付けて、この固定シート２４にポリエチレンまたはポリエチレンとポリプロピレンの複合密閉シート２５を取り付けた場合に付いて示す。飾り箱１６の保護板１７の端の部分の周囲に接着剤１３を付けてこの接着剤１３に前記ナイロンをコーティングしたポリエチレンシートのナイロン面を接着固定する。この固定シート２４の反対側のポリエチレン面にポリエチレンまたはポリエチレンとポリプロピレンの複合密閉シート２５を熱圧着接合して取り付け飾り箱の内部を密閉構造とする。In the embodiment shown in FIG. 3, a fixing sheet 24 in which a polyethylene sheet is coated with nylon is attached to the end of the protective plate 17 using an adhesive 13, and a polyethylene or polyethylene / polypropylene composite sealing sheet 25 is attached to the fixing sheet 24. It is shown when attached. An adhesive 13 is attached around the edge of the protective plate 17 of the display box 16, and the nylon surface of the polyethylene sheet coated with the nylon is adhered and fixed to the adhesive 13. A polyethylene or polyethylene / polypropylene composite sealing sheet 25 is thermocompression-bonded to the opposite polyethylene surface of the fixing sheet 24 to form a sealed structure inside the attachment decoration box.
本発明の密閉構造部は、保護板の端の部分にポリエチレンシートにナイロンをコーティングした複合固定シートのナイロン面を接着固定して、この固定シートに、ポリエチレンまたはポリエチレンとポリプロピレンの複合密閉シートに熱圧着接合するわけであるが、熱圧着はシーラーを利用すればよく、熱圧着可能な温度を発生するものであればアイロンを使用してもよく、特に設備を限定するものではない。In the sealed structure of the present invention, the nylon surface of a composite fixing sheet in which nylon is coated on a polyethylene sheet is bonded and fixed to the end portion of the protective plate, and heat is applied to the composite sealing sheet of polyethylene or polyethylene and polypropylene. For thermocompression bonding, a sealer may be used, and an iron may be used as long as it generates a temperature capable of thermocompression bonding, and the equipment is not particularly limited.
また、本発明の額縁や飾り箱は、絵画、書、写真、押し花、ドライフラワー、貴金属等を包囲体で形成された密閉空間に入れて保存するものである。そのため、密閉空間を形成する包囲体のシート部はポリエチレン、ポリプロピレン、またはそれらの複合シートさらにポリエチレンにナイロンがコーティングされたもの等が多く使用されており、その特性は接着が困難な難接着性素材である。またガラス板、アクリル板、ポリカーボネイト板も接着が困難な素材である。 Further, the frame and the display box of the present invention are for storing pictures, books, photographs, pressed flowers, dried flowers, precious metals, etc. in a sealed space formed by an enclosure. Therefore, the sheet part of the enclosure forming the sealed space is often made of polyethylene, polypropylene, or a composite sheet of these, and polyethylene coated with nylon, etc. It is. Glass plates, acrylic plates and polycarbonate plates are also difficult to bond.
この、難接着性シートと薄いガラス板、アクリル板、ポリカーボネイト板とを効率よく接合する密閉構造であり、その使用範囲も特に、額縁や飾り箱に限定するものではなく、シートと板の接合構造に使用できるものである。また、この接合構造を利用すれば材質をとくに選ばず金属、非金属の薄板とポリエチレンまたはポリエチレンとポリプロピレン等の難接着性シート材の接合に応用できる。 This is a sealed structure that efficiently joins a difficult-to-adhesive sheet to a thin glass plate, acrylic plate, polycarbonate plate, and its range of use is not particularly limited to a frame or display box. It can be used for. Moreover, if this joining structure is used, it can be applied to joining a metal, a non-metallic thin plate, and a difficult-to-adhere sheet material such as polyethylene or polyethylene and polypropylene, regardless of the material.
尚、密閉シートは、その形状は特に限定するものではなく、袋状の包囲体、上部にチャックを設けた袋、または、上部が開放した筒状のものでもよく、内部に絵画、書、版画、写真等の美術品やドライフラワーや押し花等を入れて密閉出来る構造であればどのような形状でも好い。また、密閉構造部には開閉部を有しても好く、内部のガスを吸引したり不活性ガスを供給するためのノズルを設けたものでも好い。 The shape of the sealing sheet is not particularly limited, and may be a bag-shaped enclosure, a bag provided with a chuck at the top, or a cylindrical shape with an open top, and a picture, a calligraphy, a print in the inside. Any shape can be used as long as it can be sealed with art works such as photographs, dried flowers and pressed flowers. Moreover, it is preferable to have an opening / closing part in the sealed structure part, and it is also preferable to provide a nozzle for sucking an internal gas or supplying an inert gas.
本発明は、以上説明したように構成されているので、以下に記載されるような効果を奏する。 Since the present invention is configured as described above, the following effects can be obtained.
従来は接着困難とされている難接着性のポリエチレンやポリプロピレンまたはそれらの複合材を薄いガラス製保護板、アクリル製保護板やポリカーボネイト製保護板に熱圧着接合で取り付けて固定することができる。 Conventionally difficult-to-adhere polyethylene, polypropylene, or their composites can be attached and fixed to a thin glass protective plate, acrylic protective plate, or polycarbonate protective plate by thermocompression bonding.
また、接合部の強度が充分確保されるため作品の出し入れに際して保護板と密閉シートの剥がれを未然に防ぐことができる。 In addition, since the strength of the joint portion is sufficiently ensured, it is possible to prevent the protective plate and the sealing sheet from peeling off when the work is taken in and out.
更に、接合部が綺麗に仕上がり、従来の接着材接合にみられる接合部での接着剤の凹凸、ばらつき、はみ出し等の問題がなくなる。 Further, the joint is finished neatly, and problems such as unevenness, variation, and protrusion of the adhesive at the joint as seen in conventional adhesive bonding are eliminated.
取り付けに際して個人差が生じないため、製品の安定度、信頼度が高まる。 Since there is no individual difference during installation, the stability and reliability of the product increases.
取り付けに際して、従来の接着剤接合を使用しないため作業上の安全が図られる。 At the time of attachment, since conventional adhesive bonding is not used, work safety is achieved.
また、従来の接着剤接合に比較して寸法上ほとんど差がない。 In addition, there is almost no difference in dimensions compared to conventional adhesive bonding.
また、製作に要する時間が大幅に短縮できるため、製品製造コストの低減が可能となる。 Moreover, since the time required for production can be greatly shortened, the product manufacturing cost can be reduced.
また、接合度が向上するため密閉部の気密性の向上が図れる。 Further, since the degree of joining is improved, the airtightness of the sealed portion can be improved.
密閉シートと保護板の接合が熱圧着接合のため、従来の接着剤接合のように、取り付けた後で乾燥養生時間を必要とせず、すぐに使用できる。 Since the sealing sheet and the protective plate are joined by thermocompression bonding, they can be used immediately without requiring a drying curing time after attachment, as in the case of conventional adhesive joining.
