　本発明は粘性液体、特に湿気硬化型の接着性を有する硬化性組成物又は酸素硬化型の接着性を有する硬化性組成物を、柔軟性を有する袋又は容器に収納し、外部から圧力を加えることによって当該袋又は容器を変形縮小させて内部の粘性液体を外部に吐出させる際に有効に使用されるカートリッジタイプのプラスチック容器を有する吐出装置に用いられる接合構造に関する。 The present invention accommodates a viscous liquid, particularly a moisture-curable adhesive composition or an oxygen-curable adhesive composition in a flexible bag or container and applies pressure from the outside. The present invention relates to a joining structure used for a discharge device having a cartridge type plastic container that is effectively used when the bag or container is deformed and reduced to discharge the internal viscous liquid to the outside.
　従来、湿気硬化型接着剤又は酸素硬化型接着剤等の粘性液体を吐出して塗布等を行う装置においては、接着剤が空気に触れると硬化してしまうため、接着剤が飛散するとその飛散箇所においてそのまま固まってしまって汚れの原因となる等の不都合が生じるので、空気に接触させない状態で接着剤を塗布する必要がある。 Conventionally, in a device that performs application by discharging a viscous liquid such as a moisture curable adhesive or an oxygen curable adhesive, the adhesive is cured when it comes into contact with air. Therefore, it is necessary to apply the adhesive in a state where it does not come into contact with air.
　このような空気との接触を嫌う液体を吐出して塗布等を行う装置としては、例えば特許文献１～３に記載された装置がある。 For example, there are apparatuses described in Patent Documents 1 to 3 as an apparatus for performing application by discharging a liquid that dislikes contact with air.
　このような粘性液体の吐出装置は、図６に示すように、加圧によって、プラスチック容器１００内に設けられた長尺状流路部材１０２から液送管手段１０４を通って吐出ノズルから接着剤等の粘性液体を吐出させる構成の装置である。プラスチック容器１００は、加圧タンク１０６内に設置され、加圧空気が空気供給管１０８を通って加圧タンク１０６内に供給される。 As shown in FIG. 6, such a viscous liquid discharge apparatus is configured such that, by pressurization, an adhesive is applied from a discharge nozzle through an elongated channel member 102 provided in a plastic container 100 through a liquid feeding pipe means 104. It is an apparatus configured to discharge a viscous liquid such as. The plastic container 100 is installed in the pressurized tank 106, and pressurized air is supplied into the pressurized tank 106 through the air supply pipe 108.
　長尺状流路部材１０２は、プラスチック容器本体１１０の開口部１１２に取り付けるための上端取付け部１１４を有している。長尺状流路部材１０２の下端には、開口端部１１６が形成され、その側面には複数の流路穴１１８が形成されている。開口端部１１６や流路穴１１８を通過した粘性液体１２４は、長尺状流路部材１０２の長尺状円柱管体１２０の内部に形成された長尺状流路部１２２を通過した後、液送管手段１０４を通って吐出ノズルから加圧吐出される。 The elongate flow path member 102 has an upper end attaching portion 114 for attaching to the opening 112 of the plastic container main body 110. An open end 116 is formed at the lower end of the elongate flow channel member 102, and a plurality of flow channel holes 118 are formed on the side thereof. After the viscous liquid 124 that has passed through the open end 116 and the channel hole 118 passes through the elongated channel part 122 formed inside the elongated cylindrical tube body 120 of the elongated channel member 102, Pressure is discharged from the discharge nozzle through the liquid feed pipe means 104.
　そして粘性液体を吐出した後、長尺状流路部材１０２が設けられたプラスチック容器１００のみを交換することができる、いわゆるカートリッジタイプのプラスチック容器を吐出装置は備えている。プラスチック容器１００は、通常はダンボール箱に入れられた状態で搬送される。プラスチック容器１００がダンボール箱に入れられた状態の形態ではいわゆるバックインボックスと呼ばれている。 Further, after discharging the viscous liquid, the discharge device includes a so-called cartridge type plastic container in which only the plastic container 100 provided with the long channel member 102 can be replaced. The plastic container 100 is usually conveyed in a state of being placed in a cardboard box. In a form in which the plastic container 100 is put in a cardboard box, it is called a so-called back-in box.
　そして、液送管手段の基端部と、プラスチック容器に設けられた長尺状流路部材の上端取り付け部とは、例えば、図７及び図８に示すように、密封装着手段１２６によって、密封状態で接合される構造となっていた。 Then, the base end portion of the liquid feeding means and the upper end attaching portion of the long channel member provided in the plastic container are sealed by a sealing mounting means 126 as shown in FIGS. 7 and 8, for example. The structure was joined in a state.
　従来の粘性液体吐出装置に用いられる接合構造を図７及び図８に示す。図７及び図８において、従来の接合構造１０１は、密封装着手段１２６によって、密封状態で接合される構造である。密封装着手段１２６は、固定部材１２８を有している。固定部材１２８は、中央部に挿通口１３０を開口した円筒基体１３２を有し、円筒基体１３２の下部外面に環状鍔部１３４を形成し、円筒基体１３２と環状鍔部１３４の下面形状は前記長尺状流路部材１０２の上端取付け部１１４の上面形状に対応する形状を有するように形成しかつ環状鍔部１３４の上面には受け段部１３６を形成すると共に円筒基体１３２の上部外面に雄螺子部１３８を形成した構成を有している。 7 and 8 show a joining structure used in a conventional viscous liquid discharge device. 7 and 8, the conventional joining structure 101 is a structure joined in a sealed state by the sealing mounting means 126. The seal mounting means 126 has a fixing member 128. The fixing member 128 has a cylindrical base 132 having an insertion opening 130 at the center, and an annular flange 134 is formed on the lower outer surface of the cylindrical base 132, and the bottom surface of the cylindrical base 132 and the annular flange 134 has the above-mentioned shape. The upper end mounting portion 114 of the scale-shaped channel member 102 is formed to have a shape corresponding to the upper surface shape, and a receiving step portion 136 is formed on the upper surface of the annular flange 134, and a male screw is formed on the upper outer surface of the cylindrical base 132. The portion 138 is formed.
　円筒基体１３２の下端部には内方に傾斜したテーパ部１４０が形成されている。１４２は貫通穴付キャップ部材で、円形板１４４の中央部に受け段部１３６に当接する貫通穴１４６を開穿しかつ円形板１４４の周縁部から垂設された環状側壁１４８の内面側には、プラスチック容器本体１１０の開口部１１２の円筒側壁１１２ａの外面に形成された雄螺子部１１２ｂに螺合可能な雌螺子部１５０が形成されている。１５２は締付部材で、中心部に中心穴１５４が穿設された円筒部材１５６を有し、円筒部材１５６の内周面の下部部分には締付け雌螺子部１５８が形成されている。締付部材１５２の中心穴１５４の上部部分は、図７に示すように、上部に向かって徐々に径小となるように形成されている。貫通穴付キャップ部材１４２と締付部材１５２とは、図８（ａ）に示すように組み合わされる。 A tapered portion 140 inclined inward is formed at the lower end portion of the cylindrical base 132. Reference numeral 142 denotes a cap member with a through hole, which has a through hole 146 in contact with the receiving stepped portion 136 at the center of the circular plate 144 and is provided on the inner surface side of the annular side wall 148 that is suspended from the peripheral edge of the circular plate 144 A female screw portion 150 that can be screwed into a male screw portion 112b formed on the outer surface of the cylindrical side wall 112a of the opening 112 of the plastic container body 110 is formed. A tightening member 152 has a cylindrical member 156 having a central hole 154 formed at the center, and a tightening female screw portion 158 is formed at a lower portion of the inner peripheral surface of the cylindrical member 156. As shown in FIG. 7, the upper part of the center hole 154 of the tightening member 152 is formed so as to gradually decrease in diameter toward the upper part. The cap member 142 with a through hole and the fastening member 152 are combined as shown in FIG.
　また、図７に示すように、長尺状流路部材１０２の長尺状流路部１２２として、中心部に貫通流路１５９が設けられている。そして、上端取付け部１１４は液吐出口１６０を形成する内周壁１６２と内周壁１６２から支持壁１６４によって所定間隔を介して離間した位置に設けられた外周壁１６６を有している。内周壁１６２の内径は上部部分が下部部分よりも径大となるとともに内周壁の上端面は内方に傾斜したテーパ部１６８となっている。外周壁１６６の上端部は外方に折曲されて外周段部１７０が形成されている。外周段部１７０をプラスチック容器本体１１０の開口部１１２の外周縁部に嵌合することによって長尺状流路部材１０２を開口部１１２に着脱自在に装着することができる。これらの構成は例えば特許文献１に詳述されている。 Further, as shown in FIG. 7, a through channel 159 is provided at the center as the long channel part 122 of the long channel member 102. The upper end attaching portion 114 has an inner peripheral wall 162 that forms the liquid discharge port 160 and an outer peripheral wall 166 that is provided at a position spaced apart from the inner peripheral wall 162 by a support wall 164 at a predetermined interval. An inner diameter of the inner peripheral wall 162 is larger at the upper portion than at the lower portion, and an upper end surface of the inner peripheral wall is a tapered portion 168 inclined inward. The upper end portion of the outer peripheral wall 166 is bent outward to form an outer peripheral step portion 170. By fitting the outer peripheral step 170 to the outer peripheral edge of the opening 112 of the plastic container body 110, the long channel member 102 can be detachably attached to the opening 112. These configurations are described in detail in Patent Document 1, for example.
　しかしながら、従来の接合構造では、長尺状流路部材１０２が斜めになるような力がかかると、液送管手段１０４と長尺状流路部材１０２とを接合する固定部材１２８の接合部分に追従性がないため、図８（ｂ）に示されるように、かかる接合部分に間隙Ｇが生じるおそれがあり、空気が入り込むおそれがあった。 However, in the conventional joining structure, when a force is applied so that the elongate flow path member 102 is inclined, the joining portion of the fixing member 128 that joins the liquid feeding pipe means 104 and the elongate flow path member 102 is applied. Since there is no followability, as shown in FIG. 8 (b), there is a possibility that a gap G may be generated at the joining portion, and there is a possibility that air may enter.
　そして、上述した加圧によってプラスチック容器内の粘性液体を吐出する吐出装置では、接合部分等に僅かな隙間が空くだけで、加圧タンク内の加圧された空気が入り込んでしまうため、高い気密性が要求される。このため、例えば、粘性液体が封入されたプラスチック容器内を減圧して前記プラスチック容器内から粘性液体を吸引して吐出したりする吐出装置とは、要求される気密性が異なるのである。 In the discharge device that discharges the viscous liquid in the plastic container by pressurization as described above, the pressurized air in the pressurization tank enters only by leaving a slight gap in the joining portion or the like, so that the airtightness is high. Sex is required. For this reason, for example, the required airtightness is different from a discharge device that depressurizes the inside of a plastic container in which a viscous liquid is sealed and sucks and discharges the viscous liquid from the inside of the plastic container.
　このように、加圧によって粘性液体を吐出する加圧タイプの吐出装置では、特に粘性液体が湿気硬化型接着剤又は酸素硬化型接着剤等の空気との接触を嫌う粘性液体の場合、接合部分などに僅かでも空気が入り込んでしまうと、前記粘性液体中に空気が混入することとなり、次のようなトラブルが生ずることが避けられなかった。 As described above, in a pressure type discharge device that discharges a viscous liquid by pressurization, in particular, when the viscous liquid is a viscous liquid that dislikes contact with air, such as a moisture curable adhesive or an oxygen curable adhesive, a joint portion If air enters even a small amount, the air is mixed in the viscous liquid, and the following troubles cannot be avoided.
　吐出ノズルを塗布ノズルとして、ノズル塗布作業を行う場合、粘性液体が充填された流路に入り込んだ空気は、流路中で粘性液体が非連続となる部分を作ってしまうため、ノズル塗布した際に塗布された粘性液体が欠損する箇所が生じてしまう。また、吐出ノズルからシリンジに充填作業を行う場合には、粘性液体の流路中に入り込んだ空気が気泡としてシリンジ内に混入してしまう。 When performing the nozzle application operation using the discharge nozzle as the application nozzle, the air that has entered the flow path filled with the viscous liquid creates a non-continuous portion of the viscous liquid in the flow path. A portion where the viscous liquid applied to the chip is lost is generated. In addition, when filling the syringe from the discharge nozzle, the air that has entered the flow path of the viscous liquid is mixed in the syringe as bubbles.
　一方で、粘性液体を吐出した後、長尺状流路部材が設けられたプラスチック容器を交換することができるように、いわゆるカートリッジタイプのプラスチック容器とする必要があった。 On the other hand, after discharging the viscous liquid, it was necessary to use a so-called cartridge type plastic container so that the plastic container provided with the long channel member could be replaced.

Since the other configuration is basically the same as the above-described bonding structure 10A, detailed description thereof will not be repeated. In this way, the long channel member 16A and the liquid feeding means 22B are joined.
　更に、本実施形態に係る接合構造に用いられる可撓性円筒状挿入部の別の実施の形態を図５に示す。 Furthermore, FIG. 5 shows another embodiment of the flexible cylindrical insertion portion used in the joining structure according to this embodiment.
　図５において、可撓性円筒状挿入部２４Ｃは、固定部材３６Ａに係止固定される可撓性円筒状部材３８Ｃの下端部に形成される。可撓性円筒状部材３８Ｃは、可撓性円筒状部材本体４０Ｃと、可撓性円筒状部材本体４０Ｃを固定部材３６Ａに係止固定させるための可撓性円筒状部材本体４０Ｃの外周面に形成された環状の係止固定部４２Ｃとを有して構成される。可撓性円筒状挿入部２４Ｃの挿入部本体３２Ｃには環状突起である係止部２６Ｃが設けられている。そして、長尺状流路部材１６Ｂの上端部には係止部２６Ｃと係合させられる被係止部２８Ｂが設けられている。なお、長尺状流路部材１６Ｂの外周壁８２の上端部近傍には、プラスチック容器本体１２の開口部１３との密封性をより向上させるために環状突起８６が設けられている。 In FIG. 5, the flexible cylindrical insertion portion 24C is formed at the lower end portion of the flexible cylindrical member 38C that is locked and fixed to the fixing member 36A. The flexible cylindrical member 38C has a flexible cylindrical member main body 40C and an outer peripheral surface of the flexible cylindrical member main body 40C for locking and fixing the flexible cylindrical member main body 40C to the fixing member 36A. An annular locking and fixing portion 42C is formed. The insertion portion main body 32C of the flexible cylindrical insertion portion 24C is provided with a locking portion 26C that is an annular protrusion. And the to-be-latched part 28B engaged with the latching | locking part 26C is provided in the upper end part of the elongate flow path member 16B. An annular protrusion 86 is provided in the vicinity of the upper end portion of the outer peripheral wall 82 of the long channel member 16B in order to further improve the sealing performance with the opening 13 of the plastic container body 12.

The portion 84 is configured to be larger than the inner diameter D5.
　これにより、可撓性円筒状挿入部２４Ｃを長尺状流路部材１６Ｂの上端部から内部貫通孔１４Ｂに挿入すると、長尺状流路部材１６Ｂの内部貫通孔１４Ｂの内周面で係止されることとなる。なお、長尺状流路部材１６Ｂの内部貫通孔１４Ｂに形成された径大部分８４は、更に下の方の内部貫通孔１４Ｂでは若干径が小さくなる。したがって、内部貫通孔１４Ｂの内径Ｄ６は内径Ｄ５よりも小さい。 Accordingly, when the flexible cylindrical insertion portion 24C is inserted into the internal through hole 14B from the upper end portion of the long channel member 16B, the flexible cylindrical insertion portion 24C is locked on the inner peripheral surface of the internal through hole 14B of the long channel member 16B. Will be. The large diameter portion 84 formed in the internal through hole 14B of the long channel member 16B has a slightly smaller diameter in the lower internal through hole 14B. Therefore, the inner diameter D6 of the internal through hole 14B is smaller than the inner diameter D5.
　すなわち、可撓性円筒状挿入部２４Ｃに設けられた係止部２６Ｃが挿入部側径大部であり、長尺状流路部材１６Ｂに設けられた被係止部２８Ｂが、挿入部側径大部に対応して長尺状流路部材１６Ｂの内部貫通孔１４Ｂに形成された被挿入部側径小部である。このように構成することで、可撓性円筒状挿入部２４Ｃを長尺状流路部材１６Ｂの上端部から内部貫通孔１４Ｂに挿入することで可撓性円筒状挿入部２４Ｃが長尺状流路部材１６Ｂに係止される構造にすることができる。その他の構成については、上述した接合構造１０Ａと基本的に同様の構成であるため再度の詳細な説明は省略する。 That is, the locking portion 26C provided in the flexible cylindrical insertion portion 24C is the insertion portion side large diameter portion, and the locked portion 28B provided in the long channel member 16B is the insertion portion side diameter. The inserted portion side small diameter portion is formed in the internal through hole 14B of the elongated flow path member 16B corresponding to the large portion. With this configuration, the flexible cylindrical insertion portion 24C is inserted into the internal through-hole 14B from the upper end portion of the elongated flow path member 16B, so that the flexible cylindrical insertion portion 24C becomes a long flow.
