(D) 考案の構成
本考案のかかる目的は、熱バーの被シール材料
圧着表面に耐熱性のある弾性材料を設ける事によ
つて達成される。(D) Structure of the invention This object of the invention is achieved by providing a heat-resistant elastic material on the surface of the heat bar to which the material to be sealed is crimped.
一般に熱バーは、130〜180℃に加熱されるため

℃以上の耐熱性のあるアクリルゴム、エチレン酢
ビゴム、ヒドリンゴム、シリコンゴム、フツソゴ
ム等を使用する事により、安定して被シール材料
をヒートシールする事が出来る。 Generally, heat bars are heated to 130 to 180℃, so the heat-resistant elastic material used in this invention is 180℃.
By using acrylic rubber, ethylene acetate rubber, hydrin rubber, silicone rubber, fluorine rubber, etc. that are heat resistant to temperatures above ℃, the material to be sealed can be stably heat-sealed.
(E) 実施例 以下本考案を図面に基づいて詳細に説明する。(E) Examples The present invention will be explained in detail below based on the drawings.
第１図は本考案の一実施態様を示す、熱バー対
の概略図である。 FIG. 1 is a schematic diagram of a pair of heat bars, showing one embodiment of the present invention.
接着する材料２は筒状の長尺物であつて、断面
が図の様に両端が内部に折り込まれたガセツト型
で、両端部は４枚、中央部では２枚と重ね厚みが
違う被ヒートシール材料である。熱バー３ａ，３
ｂは熱源４ａ，４ｂにより所定の温度になる様に
温度計５ａ，５ｂにて測定し、温度制御装置６
ａ，６ｂによつて調整される。 The material to be bonded 2 is a long cylindrical material with a gusset cross-section, with both ends folded inward as shown in the figure, with 4 sheets at both ends and 2 sheets at the center, which are stacked to be heated and have different thicknesses. It is a sealing material. Heat bar 3a, 3
b is measured by thermometers 5a and 5b so that the temperature reaches a predetermined value using heat sources 4a and 4b, and temperature control device 6
a, 6b.
材料２を熱バー３ａ，３ｂで挾み圧着した時、
材料２の枚数が両端と中央で差があるが、弾性材
料１は材料２の枚数厚さに合せて変形し、密着す
るので均一かつ効果的に材料２に熱と圧力を加え
る事が可能となり優れたヒートシール性をもたら
す。 When material 2 is sandwiched and crimped between heat bars 3a and 3b,
There is a difference in the number of sheets of material 2 between the ends and the center, but elastic material 1 deforms according to the number and thickness of material 2 and comes into close contact, making it possible to apply heat and pressure to material 2 uniformly and effectively. Provides excellent heat sealability.
弾性材料１の材質としては耐熱性のすぐれた前
掲のゴム材が使用可能であるが、硬度は20〜100
（JIS−Ａ）の範囲が適当であり、例えばシリコン
ゴム、フツ素ゴム等が有利に用いられる。 As the material of the elastic material 1, the above-mentioned rubber material with excellent heat resistance can be used, but the hardness is 20 to 100.
(JIS-A) is suitable, and silicone rubber, fluorine rubber, etc. are advantageously used.
この場合、硬度が大きいと被シール材料に対し
て圧力を掛けやすくなるが、被シール材料枚数厚
さに対する変形が悪くなり接着性が不十分とな
る。一方硬度を小さくすると被シール材料枚数厚
さに対して変形しやすくなるが、圧力が掛けにく
くなり被シール材料の接着が十分行なわれなくな
り好ましくない。 In this case, if the hardness is high, it becomes easier to apply pressure to the material to be sealed, but the deformation of the material to be sealed with respect to the number and thickness of the materials becomes worse, resulting in insufficient adhesion. On the other hand, if the hardness is reduced, the material to be sealed will easily deform depending on the number and thickness of the material to be sealed, but it will be difficult to apply pressure and the materials to be sealed will not be sufficiently bonded, which is not preferable.
本実施例として示した様に熱バーのいずれか一
方に弾性体１を設けたものあるいは熱バー対の双
方に設けたものであつてもよい。弾性材料１は熱
バー表面に接着剤にて接着することにより設ける
ことができる。 As shown in this embodiment, the elastic body 1 may be provided on either one of the heat bars or may be provided on both of the pair of heat bars. The elastic material 1 can be provided by adhering to the surface of the thermal bar with an adhesive.
弾性材料１の厚みは被シール材厚み及び必要と
する熱量等を考慮し決定されるが通常１〜20mm、
好ましくは５〜10mm程度である。厚みが大きくな
りすぎると熱伝導が悪くなり被シール材料の接着
が不十分となる。一方厚みが小さくなりすぎると
熱バー表面の弾性が小さくなり、ガセツト型被シ
ール材料の接着が不均一となるので好ましくな
い。 The thickness of the elastic material 1 is determined by considering the thickness of the material to be sealed and the amount of heat required, but is usually 1 to 20 mm.
Preferably it is about 5 to 10 mm. If the thickness is too large, heat conduction will be poor and adhesion of the material to be sealed will be insufficient. On the other hand, if the thickness is too small, the elasticity of the surface of the heating bar will be reduced and the adhesion of the gusset type sealed material will become uneven, which is not preferable.
被シール材料として高密度ポリエチレンを使用
したガセツト包のヒートシールを本考案と従来方
法で比較した。 Heat sealing of gusset packaging using high-density polyethylene as the material to be sealed was compared between the present invention and the conventional method.
本考案のヒートシール装置として厚さ７mmのシ
リコンゴムを金属性熱バー表面に設けたもの、従
来方法として金属性熱バー表面にシリコンゴムを
設けていないものを用いた。 As the heat sealing device of the present invention, a device in which silicone rubber with a thickness of 7 mm was provided on the surface of the metallic heating bar was used, and as a conventional method, a device in which silicone rubber was not provided on the surface of the metallic heating bar was used.
