Description

本発明は、大型封筒、書類袋、ボール箱、容器等における蓋を閉じるために用いる留め具に関する。 The present invention relates to a fastener used for closing a lid of a large envelope, a document bag, a cardboard box, a container or the like.

従来の留め具としては、裏面に接着層を有する張付基材と、該張付基材の表側と中心部において付着されて重ね合わされた掛止盤と、からなる一対の留め具からなり、一方の留め具は、前記張付基材と掛止盤との間に掛け紐が一緒に付着されてなるものが一般的に知られている。これら張付基材及び掛止盤は塩化ビニールのような熱可塑性合成樹脂からなり、これらの中心部に型電極を当てて高周波ウエルダにより溶着させることにより、張付基材と掛止盤の中心部が接着される。紐付き留め具の場合には、同時に掛け紐が張付基材と掛止盤の中心部において結合される（例えば、特許文献１、特許文献２参考。）。
また、張付基材と掛止盤とを紙製とし、互いの対面側の中心部をホットメルトにより接着したものもある。 As a conventional fastener, it is composed of a pair of fasteners composed of a tension base material having an adhesive layer on the back surface, and a clasp attached and superposed on the front side and the center of the tension base material. Is generally known in which a hanging string is adhered together between the tension base and the retaining plate. These base materials and retaining plates are made of thermoplastic synthetic resin such as vinyl chloride, and the center portion of the base material and the retaining plate are bonded together by applying a mold electrode to these central portions and welding them with a high frequency welder. The In the case of the fastener with the string, the hanging string is simultaneously coupled at the center of the tensioning base material and the retaining disk (for example, see Patent Document 1 and Patent Document 2).
In some cases, the tension base and the retaining plate are made of paper, and the center portions of the facing sides are bonded by hot melt.

特公平６−４５２０３号公報（第４欄第１０行〜第２２行）Japanese Examined Patent Publication No. 6-45203 (column 4, lines 10 to 22) 特公平５−６０７８５号公報（第３欄第１９行〜第４欄第１行）Japanese Patent Publication No. 5-60785 (column 3, line 19 to column 4, line 1)

しかしながら、従来の留め具では、張付基材と掛止盤とが熱可塑性合成樹脂で成るため、これらの中心部を高周波ウエルダで接着させる際に、型電極が当たった中心部が溶融して接着されるため、この部分に型電極の形状に沿った深い凹凸が形成されてしまう。このため、掛止盤の表面には模様を印刷することができる範囲が限られてしまい、全面に模様を印刷することができない。また、仮に、表面全面にオフセット印刷を行っても、前記深い凹凸が印刷部分に形成されて、印刷した模様が崩れてしまうため、オフセット印刷にも適さない。このように、熱可塑性合成樹脂製の掛止盤を備えた留め具では、デザイン性に欠けるという問題がある。 However, in the conventional fastener, the base material and the retaining plate are made of a thermoplastic synthetic resin. Therefore, when these central portions are bonded with a high-frequency welder, the central portion hit by the mold electrode is melted and bonded. Therefore, deep irregularities along the shape of the mold electrode are formed in this portion. For this reason, the range in which the pattern can be printed is limited on the surface of the retaining plate, and the pattern cannot be printed on the entire surface. Further, even if offset printing is performed on the entire surface, the deep unevenness is formed in the printed portion and the printed pattern is destroyed, so that it is not suitable for offset printing. Thus, the fastener provided with the thermoplastic synthetic resin retaining plate has a problem of lack of design.

また、紙製の張付基材と掛止盤とをホットメルトで接着した留め具では、掛止盤の表面に凹凸が形成されないため、掛止盤の表面全体に模様を印刷したりオフセット印刷したりすることはできる。しかし、車内など高温になる所では、ホットメルトが溶けてしまうため、張付基材から掛止盤が外れてしまい、留め具の機能を果たすことができなくなるという問題がある。 In addition, in the case of a clasp with a hot-melt bonded base material made of paper and a clasp, no irregularities are formed on the surface of the clasp, so a pattern can be printed or offset printed on the entire surface of the clasp. Can do. However, since the hot melt melts at a high temperature such as in a vehicle, there is a problem that the latching plate is detached from the tension base material and the function of the fastener cannot be achieved.

本発明は、かかる課題に鑑みなされたもので、掛止盤の表面全体への模様の印刷やオフセット印刷など、自由に印刷することができるとともに、使用場所での温度環境に左右されずにその機能を果たすことができる留め具を提供することをその目的とする。 The present invention has been made in view of such problems, and can be freely printed, such as pattern printing or offset printing on the entire surface of the retaining plate, and is not affected by the temperature environment at the place of use. It is an object to provide a fastener that can perform a function.

請求項１記載の発明によれば、掛止盤の表面と裏面との間に金属製の中間層を挟んだことにより、中間層によりウエルダの高周波が増幅されてウエルダの効きが良くなる。これにより、表面の紙の厚さを厚くすることができるので、張付基材との接着時に型電極を当てることにより発生する中央部の凹凸を少なくすることができる。従って、掛止盤の表面全体にわたって模様を印刷することができ、また、表面の素材が紙であるため、容易にオフセット印刷による多色刷りをすることもできるので、デザイン性を向上させることができる。さらに、掛止盤の裏面が熱可塑性樹脂であり、熱可塑性樹脂製の張付基板とは高周波ウエルダにより溶融接着されるため、車内などの高温になる場所でも溶け剥れることはない。したがって、使用場所での温度環境に左右されずにその機能を果たすことができる留め具を提供することができる。 According to the invention 請 Motomeko 1 wherein, by sandwiching the metallic intermediate layer between the surface and the back surface of the latching panel is the intermediate layer is a high-frequency welder amplification effectiveness of welder is improved. Thereby, since the thickness of the paper on the surface can be increased, it is possible to reduce the unevenness of the central portion generated by applying the mold electrode when adhering to the tension base. Therefore, it is possible to print a pattern over the entire surface of the clasp, and since the material of the surface is paper, it is possible to easily perform multicolor printing by offset printing, so that the design can be improved. . Further, the back surface of the retaining plate is made of a thermoplastic resin, and is melted and bonded to the stretched substrate made of the thermoplastic resin by a high-frequency welder. Therefore, it is possible to provide a fastener that can perform its function without being influenced by the temperature environment at the place of use.

Thus, the lid 78a of the box 78 can be closed. Since the fastener 10 has a paper surface layer, offset printing can be performed, and unevenness due to the mold electrode becomes shallow, so that it can be printed in a color or pattern that matches the color or pattern of the box 78. The overall appearance including the box 78 can be improved.

なお、留め具は、封筒や箱だけに使用されるものではなく、容器など、様々なものに使用することができる。さらに、蓋をする物の大きさやデザイン性などに応じて、適宜数の留め具を用いることができる。また、留め具の使用状態により、適宜長さの掛け紐を用いることができる。 In addition, a fastener is not used only for an envelope and a box, but can be used for various things, such as a container. Furthermore, an appropriate number of fasteners can be used according to the size, design, etc. of the object to be covered. Moreover, depending on the state of use of the fastener, an appropriate length of strap can be used.

次に、本発明の留め具の実施形態を説明する。
図２（ａ）、（ｂ）は、紐付き留め具４０及び紐無し留め具５０のそれぞれの断面図である。図において、紐付き留め具４０及び紐無し留め具５０は、大略的にそれぞれ、張付基材４２、５２と、掛止盤４６、５６とを有している。 Next, the implementation form of the fastener of the present invention.
2A and 2B are cross-sectional views of the corded fastener 40 and the cordless fastener 50, respectively. In the figure, the stringed fastener 40 and the stringless fastener 50 generally have tension bases 42 and 52 and retaining plates 46 and 56, respectively.

張付基材４２、５２は、円盤形状をなしており、剥離紙３０に対して剥離可能となった接着層４３、５３を裏面に有している。また、張付基材４２、５２の接着層４３、５３の上面には、ポリ塩化ビニールで形成されたＰＶＣ層４４、５４が形成されており、ＰＶＣ層４４、５４の厚みは、０．１〜０．２ｍｍに設定されており、好適には約０．１５ｍｍ程度である。 The tension base materials 42 and 52 have a disk shape and have adhesive layers 43 and 53 that can be peeled off from the release paper 30 on the back surface. In addition, PVC layers 44 and 54 made of polyvinyl chloride are formed on the upper surfaces of the adhesive layers 43 and 53 of the tension base materials 42 and 52. The thickness of the PVC layers 44 and 54 is 0.1 to 0. .2 mm, preferably about 0.15 mm.

一方の掛止盤４６、５６も、張付基材４２、５２とほぼ同形の円盤形状をなしており、張付基材４２、５２と対面する裏面はポリ塩化ビニールで形成されたＰＶＣ層４７、５７が形成されている。また、掛止盤４６、５６の表面には紙で形成された表面層４８，５８が形成されており、ＰＶＣ層４７、５７と表面層４８、５８との間には中間層４９、５９が挟まれて全体で３層構造をなしている。中間層４９、５９はアルミニウム製等の金属製シートで、中間層４９、５９とＰＶＣ層４７、５７及び表面層４８、５８とは接着剤により互いに貼り合わされている。中間層４９、５９に用いられているアルミニウム製等の金属製シートは、高周波ウエルダの高周波を増幅させる効果を有するため、ＰＶＣ層４７、５７と表面層４８、５８との間に中間層４９、５９を挟むことにより、掛止盤４６、５６と張付基材４２、５２との接着が良好になる。 One of the retaining plates 46 and 56 also has a disk shape substantially the same as that of the tensioning base materials 42 and 52, and PVC layers 47 and 57 made of polyvinyl chloride are formed on the back surface facing the tensioning base materials 42 and 52. Has been. Further, surface layers 48 and 58 made of paper are formed on the surfaces of the latching plates 46 and 56, and intermediate layers 49 and 59 are provided between the PVC layers 47 and 57 and the surface layers 48 and 58, respectively. It is sandwiched to form a three-layer structure as a whole. The intermediate layers 49 and 59 are metal sheets made of aluminum or the like, and the intermediate layers 49 and 59, the PVC layers 47 and 57, and the surface layers 48 and 58 are bonded to each other with an adhesive. Since the metal sheet made of aluminum or the like used for the intermediate layers 49 and 59 has an effect of amplifying the high frequency of the high frequency welder, the intermediate layer 49, between the PVC layers 47 and 57 and the surface layers 48 and 58, By sandwiching 59, adhesion between the retaining plates 46 and 56 and the tension base materials 42 and 52 is improved.

ＰＶＣ層４７、５７の厚みは０．０５〜０．１５ｍｍに設定されており、好適には約０．０９ｍｍ程度である。また、中間層４９、５９の厚みは約０．０１〜０．０５ｍｍに設定されており、好適には約０．０２〜０．０３ｍｍである。表面層４８、５８の厚みは０．２〜１．０ｍｍに設定されている。表面層４８、５８の厚み寸法は、後述する高周波ウエルダによる張付基材４２、５２との接着が可能になる好適な値に設定されているが、金属製シートからなる中間層４９、５９によって厚さを厚くすることができる。 The thickness of the PVC layers 47 and 57 is set to 0.05 to 0.15 mm, and is preferably about 0.09 mm. The thickness of the intermediate layers 49 and 59 is set to about 0.01 to 0.05 mm, and preferably about 0.02 to 0.03 mm. The thickness of the surface layers 48 and 58 is set to 0.2 to 1.0 mm. Thickness of the surface layer 48 and 58 has been set to a suitable value that the adhesive is capable of with by high frequency welder clad base material 4 2, 5 2, which will be described later, by an intermediate layer 49, 59 made of a metal sheet The thickness can be increased.

前記のように構成されている張付基材４２、５２と掛止盤４６、５６とを高周波ウエルダにより接着して紐付き留め具４０と紐無し留め具５０とをそれぞれ構成するが、その製造方法は参考形態と同様であるため、説明を省略する。 While composing said so constructed leash fasteners and are pinning substrate 42, 52 and the hooking plate 46 and 56 are adhered by the high-frequency welder 40 and the cord without fasteners 50 respectively, and its method of manufacture Reference Since it is the same as that of a form, description is abbreviate | omitted.

なお、張付基材４２、５２と掛止盤４６、５６の高周波ウエルダによる接着の際に、掛止盤４６、５６の表面層４８、５８が紙で形成されているため、掛止盤４６、５６はこれの裏面のＰＶＣ層４７、５７のみが溶融して張付基材４２、５２に接着する。一方、掛止盤４６、５６の紙製の表面層４８、５８は溶融しないため、張付基材４２、５２との接着時に型電極を当てることにより発生する中央部の凹凸が少ない。表面層４８、５８を厚くすることができるため、凹凸を一層少なくすることができる。従って、掛止盤４６、５６の表面全体にわたって模様を印刷することができ、また、表面の素材が紙のため、オフセット印刷による多色刷りも容易に行うことができるので、デザイン性を向上させることができる。さらに、掛止盤４６、５６の裏面がポリ塩化ビニールであり、張付基材４２、５２のＰＶＣ層４４、５４とは高周波ウエルダによる溶融接着のため、車内などの高温になる場所でも溶け剥れることはない。 Since the surface layers 48 and 58 of the latching plates 46 and 56 are formed of paper when the tensioning base materials 42 and 52 and the latching plates 46 and 56 are bonded by the high-frequency welder, the latching plates 46 and 56 are formed. In this case, only the PVC layers 47 and 57 on the back surface thereof are melted and bonded to the pasting substrates 42 and 52. On the other hand, since the paper surface layers 48 and 58 of the retaining plates 46 and 56 are not melted, there is little unevenness in the central portion generated by applying the mold electrode when adhering to the tension substrates 42 and 52. Since the surface layers 48 and 58 can be made thicker, the unevenness can be further reduced. Therefore, a pattern can be printed over the entire surface of the retaining plates 46 and 56, and since the material of the surface is paper, multicolor printing by offset printing can be easily performed, thereby improving the design. Can do. Furthermore, the back surfaces of the retaining plates 46 and 56 are made of polyvinyl chloride, and the PVC layers 44 and 54 of the base materials 42 and 52 are melted and bonded by a high-frequency welder, so that they can be melted away even in a place where the temperature is high such as in a car. There is no.

また、紐付き留め具４０と紐無し留め具５０との使用方法も参考形態と同様であるため、説明を省略する。 Moreover, since the usage method of the fastener 40 with a string and the fastener 50 without a string is also the same as that of a reference form, description is abbreviate | omitted.

次に、表面層１５、２５、４８、５８の厚みと、高周波ウエルダによる掛止盤１６、２６、４６、５６と張付基材１２、２２、４２、５２との接着の可否との関係を測定した実験について説明する。 Next, the surface layer 15,25,48, measuring the thickness of 5 8, the relationship between whether adhesion of the locking plate 16,26,46,56 and Chozuke substrate 12,22,42,52 by high frequency welder The experiment that was performed will be described.

（実験例１）
中間層４９、５９を入れない参考形態の場合について、接着する前の、０．２６ｍｍの表面層１５、２５を有する掛止盤１６、２６と、張付基材１２、２２とを用意し、さらに、厚み０．０９ｍｍの紙を複数枚用意した。紙を１枚ずつ表面層１５、２５上に載置して表面層１５、２５の上に重ね合わせた状態で、高周波ウエルダを当てて接着を行い、接着が可能かどうかを確認し、重ね合わせる紙の枚数を順に増加していった。
その結果、表面層１５、２５上に重ね合わせる紙が３枚までは、高周波ウエルダを当てると、掛止盤１６、２６と張付基材１２、２２とが接着されることが確認された。
これに対して、表面層１５、２５上に重ね合わせる紙が４枚以上になると、高周波ウエルダを当てても、掛止盤１６、２６と張付基材１２、２２とが接着されなかった。
以上の結果より、３枚の紙を重ね合わせたことに相当する表面層１５の厚みが０．５３ｍｍ以下であれば、中間層４９、５９を入れなくても、掛止盤１６、２６と張付基材１２、２２とが接着されるが、４枚以上の紙を重ね合わせたことに相当する表面層１５，２５の厚みが少なくとも０．６２ｍｍになると、接着されないことが分かる。 (Experimental example 1)
For the case of the reference form in which the intermediate layers 49 and 59 are not inserted, the latching plates 16 and 26 having the surface layers 15 and 25 of 0.26 mm and the base materials 12 and 22 before the bonding are prepared. A plurality of sheets having a thickness of 0.09 mm were prepared. In a state where the paper is placed on the surface layers 15 and 25 one by one and superimposed on the surface layers 15 and 25, adhesion is performed by applying a high frequency welder, and whether or not the adhesion is possible is confirmed and superimposed. The number of sheets increased in order.
As a result, it was confirmed that when up to three sheets of paper to be superimposed on the surface layers 15 and 25 were applied with the high-frequency welder, the clasps 16 and 26 and the tension bases 12 and 22 were bonded.
On the other hand, when the number of sheets to be overlaid on the surface layers 15 and 25 is four or more, the retaining plates 16 and 26 and the tension bases 12 and 22 are not bonded even when the high frequency welder is applied.
From the above results, if the thickness of the surface layer 15 corresponding to the overlap of the three sheets of paper is 0.53 mm or less, the clasps 16 and 26 and the sticking base are not necessary even if the intermediate layers 49 and 59 are not inserted. Although the materials 12 and 22 are bonded, it can be seen that when the thickness of the surface layers 15 and 25 corresponding to the overlap of four or more sheets is at least 0.62 mm, they are not bonded.

（実験例２）
一方、アルミニウム製の中間層４９、５９を入れた実施形態の場合について同様の実験を行ったところ、表面層４８、５８の厚みが０．６２ｍｍであっても掛止盤４６、５６と張付基材４２、５２とが接着されることが確認された。
従って、紙製の表面層を用いる場合、その厚みが０．５ｍｍ以上の場合は中間層４９、５９を入れたほうが確実に接着することができることが分かる。逆に言えば、中間層４９，５９を入れることにより、紙厚の厚い表面層を用いることができ、紙厚が厚ければ厚いほど、型電極の形状に沿った凹凸が形成され難くなり、凹凸が浅くなるため、掛止盤の表面の外観をより一層向上させることができる。 (Experimental example 2)
On the other hand, if Toko was subjected to similar experiments for the implementation form containing the aluminum intermediate layer 49 and 59, also the thickness of the surface layer 48 and 58 is a 0.62mm and hooking plate 46, 56 It was confirmed that the pasting base materials 42 and 52 were adhered.
Therefore, when using a paper surface layer, when the thickness is 0.5 mm or more, it can be seen that the intermediate layers 49 and 59 can be bonded more reliably. In other words, by adding the intermediate layers 49 and 59, it is possible to use a surface layer having a thick paper thickness. The thicker the paper thickness, the harder the unevenness along the shape of the mold electrode is formed. Since the unevenness becomes shallow, the appearance of the surface of the retaining plate can be further improved.
