［産業上の利用分野］
この発明は、ヒートシールすべき部材の圧接す

に表面に凹凸を有するヒートシール対象部材に適
したヒートシール装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a heat sealing device in which the structure of the pressure-contacting part of a member to be heat-sealed is improved, and is particularly suitable for a heat-sealing target member having an uneven surface. The present invention relates to a heat sealing device.
［従来の技術］

れることが要求される。[Conventional technology] To ensure sealing by heat sealing,
It is desirable that the portion of the member to be heat sealed has good flatness. However, in some cases, there may be some unevenness in the area to be heat-sealed. When unevenness exists, it is required that the sealing material be reliably fixed along the unevenness of the surface.
そこで、従来より、第４図に示すヒートシール
装置が用いられている。ここでは、加熱基板１内
にヒータ２が埋め込まれており、該ヒータ２に通
電することにより加熱基板１が加熱される。 Therefore, a heat sealing device shown in FIG. 4 has been conventionally used. Here, a heater 2 is embedded in the heating substrate 1, and the heating substrate 1 is heated by supplying electricity to the heater 2.

一なシールを行ない得るようにされている。 The heating substrate 1 is usually made of a metal material in order to efficiently transmit heat. Therefore, if there are small irregularities or the like in the part to be heat-sealed, it is difficult to uniformly seal the entire part to be heat-sealed if the heating substrate 1 is directly pressed against the part. Therefore, an elastic member 3 made of heat-resistant rubber is attached to the side of the heating substrate 1 that comes into contact with the member to be heat-sealed. This allows unevenness of the heat-sealed member to be absorbed and uniform sealing to be performed.
［発明が解決しようとする問題点］
しかしながら、ヒートシールが行なわれる部材
には種々のものが存在する。たとえば、容器の開
口部を封止材を使つてヒートシールする場合を例
にとれば、容器が、金属、ガラスまたは硬質プラ
スチツクスなどの変形し難い材料からなる場合に

ない。よつて、弾性部材３の厚みを或る程度厚く
しなければ、確実にヒートシールを行なうことが
できない。[Problems to be Solved by the Invention] However, there are various members to which heat sealing is performed. For example, if the opening of a container is heat-sealed using a sealant, if the container is made of a material that is difficult to deform, such as metal, glass, or hard plastic, the parts to be heat-sealed are You can't expect side deformation. Therefore, unless the thickness of the elastic member 3 is increased to a certain extent, heat sealing cannot be performed reliably.
さらに、ヒートシールすべき部分が平坦でない
場合にはより問題となる。たとえば第５図に部分
切欠き断面図で示すように、ヒートシールを行な
うべき上端開口に平坦な上端面４以外に、該平坦
面４に連なつて傾斜面５，６が設けられている容

かシールされ得ない。すなわち、弾性部材３の弾
力性をもつてしても、傾斜面５，６の領域におい
てもシールを施すことは極めて困難であつた。 Furthermore, it becomes more problematic when the area to be heat sealed is not flat. For example, as shown in a partially cutaway cross-sectional view in FIG. 5, a container is provided with sloped surfaces 5 and 6 connected to the flat surface 4 in addition to a flat top surface 4 at the top opening to be heat-sealed. exists. In this type of container, the inclined surfaces 5, 6
is formed to be inclined downward from the flat surface 4, so even if a thermoplastic resin film or the like is placed over the top of the container and heat sealing is performed using the heat sealing device shown in FIG. Only 4 can be sealed. That is, even with the elasticity of the elastic member 3, it is extremely difficult to seal the areas of the inclined surfaces 5 and 6.
特に、第５図に示した容器７が、剛性の比較的
高い金属材料またはガラス等から構成されている
場合には、容器７の側での変形を期待することが
できない。したがつて、傾斜面５，６におけるシ
ールは事実上不可能となつていた。そのため、十
分なシール強度を得るには、上方の平坦面４の面
積をより大きくしなければならなかつた。 In particular, if the container 7 shown in FIG. 5 is made of a relatively rigid metal material, glass, or the like, deformation on the container 7 side cannot be expected. Therefore, sealing on the inclined surfaces 5 and 6 has become virtually impossible. Therefore, in order to obtain sufficient sealing strength, the area of the upper flat surface 4 had to be made larger.
上記の問題は、第５図に示した容器７に限ら
ず、第６図に示すように開口周縁から内側下方に
延びる傾斜面８を有する容器９、または第７図に
示すように開口周縁の平坦面１１の両側が丸みを
つけられている容器１２においても同様であつ
た。 The above problem is not limited to the container 7 shown in FIG. 5, but also to the container 9 which has an inclined surface 8 extending inward and downward from the opening periphery as shown in FIG. The same was true for the container 12 in which both sides of the flat surface 11 were rounded.
もつとも、ヒートシールすべき部材の外形に沿
う圧接面を備える加熱基板を用いれば、上記問題
は解消され得るとも考えられる。しかしながら、
ヒートシールすべき部材は種々存在し、一般に
は、ヒートシール装置には、或る程度汎用性が要
求される。したがつて、個々のヒートシール対象
部材の外形に合わせて、種々の加熱基板を準備す
ることは煩雑であり、また多額の費用がかかるこ
とになる。 However, it is thought that the above problem can be solved by using a heating substrate having a pressure contact surface that follows the outer shape of the member to be heat sealed. however,
There are various members to be heat-sealed, and generally a heat-sealing device is required to have a certain degree of versatility. Therefore, preparing various heating substrates according to the external shape of each member to be heat-sealed is complicated and requires a large amount of cost.
さらに、第４図に示した従来のヒートシール装
置では、加熱基板の圧接面側に弾性部材３が貼り
付けられているが、弾性部材３は、通常、ゴム等
よりなるため、熱伝導性が悪いという問題もあつ
た。すなわち、弾性部材３は、ヒートシール対象
部材の表面の凹凸を吸収するために設けられてい
るものであるが、第５図ないし第７図に示したよ
うなヒートシール対象部材の外形自体が平坦でな
い場合には、その厚みをよほど厚くしなければヒ
ートシール対象部材の外形に沿わせることはでき
ない。 Furthermore, in the conventional heat sealing device shown in FIG. 4, an elastic member 3 is attached to the pressure contact side of the heating substrate, but since the elastic member 3 is usually made of rubber or the like, it has poor thermal conductivity. There was also the problem that it was bad. That is, the elastic member 3 is provided to absorb unevenness on the surface of the heat-sealed member, but when the outer shape of the heat-sealed member itself is flat as shown in FIGS. If not, it cannot be made to follow the outer shape of the member to be heat-sealed unless the thickness is made very thick.
他方、弾性部材３の厚みが厚くなりすぎると、
前述のように熱伝導性が低下し、ヒートシール装
置の熱的効率が低下することになる。 On the other hand, if the elastic member 3 becomes too thick,
As mentioned above, the thermal conductivity is reduced and the thermal efficiency of the heat sealing device is reduced.
のみならず、弾性部材３の厚みを厚くするだけ
では、第５図ないし第７図に示したような断面形
状を有するヒートシール対象部材に確実にシール
を行なうことは不可能であつた。 Furthermore, simply by increasing the thickness of the elastic member 3, it has been impossible to reliably seal a member to be heat-sealed having a cross-sectional shape as shown in FIGS. 5 to 7.
それゆえに、この発明の目的は、比較的簡単な
構造で、ヒートシール対象部材の材質および外形
の如何にかかわらず、広いシール面積を確保する
ことが可能なヒートシール装置を提供することに
ある。 Therefore, an object of the present invention is to provide a heat sealing device that has a relatively simple structure and is capable of ensuring a wide sealing area regardless of the material and external shape of the member to be heat sealed.

This invention provides an improvement in a device that performs heat sealing by being directly or indirectly pressure-welded, and in this invention, a metal body that is flexible at the heat-sealing temperature is attached to the part that is pressure-welded to the part to be heat-sealed. A room-temperature recrystallizable metal (including alloys thereof; the same shall apply hereinafter) is attached.

Furthermore, since a metal body recrystallizable at room temperature is used instead of a conventional elastic member made of rubber or the like, there is no risk of a decrease in thermal conductivity.

The heating substrate 21 is made of a material with excellent thermal conductivity, such as a metal material, similar to the heating substrate in a conventional heat sealing device. Note that the heating means is not limited to an electric heater such as the heater 22, but may also be a fluid heat source such as steam.

おいても、加熱基板２１と大差ないものである。
ところで、熱可塑性合成樹脂を用いてヒートシー

の範囲で選択される。 A housing section that is open toward the heat-sealing target member is formed below the heating substrate 21, and a room-temperature recrystallizable metal body 23 is stored in the housing section. The room-temperature recrystallizable metal body is made of a metal material such as lead, antimony, tin, silver, gold, or zinc, or an alloy material thereof, and recrystallizes at room temperature, so it has flexibility at the heat-sealing temperature. There is.
Therefore, when pressed against a member to be heat-sealed, it can be very easily deformed along the outer shape of the member to be heat-sealed. Also, in terms of thermal conductivity, it is not much different from the heating substrate 21.
By the way, when heat-sealing thermoplastic synthetic resin, the heat-sealing temperature is usually 100 to 250℃.

may expand outward as pressure is continued to be used, but it also has the function of preventing this.

設けられる。 In the embodiment shown in FIGS. 1 and 2, the room-temperature recrystallizable metal bodies 23, 33 are attached using the frame materials 24, 34, 35, but the enlarged cross-sectional view is shown in FIG. As shown, a room temperature recrystallizable metal body 4
3 may be embedded in the heating substrate 41. In this case, an opening 41a is formed below the heating substrate 41 at a portion that abuts the member to be heat-sealed. Therefore, the member 46 to be heat-sealed and the lid member 47 enter the heating substrate 41 through the opening 41a as shown in the figure, and are pressed against the room-temperature recrystallizable metal band 43. Reference numeral 49 indicates a through hole, which is provided as necessary to allow the room temperature recrystallizable metal body 43 to escape.

ため、シールコストの増大を招くこともない。[Effects of the Invention] In this invention, since the room temperature recrystallizable metal body is attached to the heating substrate part that is pressed against the part to be heat-sealed, when it is pressed against the member to be heat-sealed during heat-sealing, The room-temperature recrystallizable metal body deforms along the outer shape of the member to be heat-sealed. Therefore, a wide sealing area can be secured regardless of the material and shape of the members to be heat-sealed, and thus various members to be heat-sealed can be reliably heat-sealed. Further, since there is no need to process the shape of the heating substrate to match the outer shape of the member to be heat-sealed, there is no need to increase the sealing cost.
