ここで、ペン先１０内の吐出口１６側（充填部１１の充填領域１０ｘの先端側）には、温度変化等によって吐出口１６から塗布材Ｍが吐出してしまうのを抑制するために適正化された所定空間Ｈが形成されている。所定空間Ｈは、ペン先１０の内壁及び塗布材Ｍの前端面で画設されている。この所定空間Ｈは、充填部１１の側方を押圧し、充填部１１内の容積が減少するように充填部１１を変形させた状態で、充填部１１の後端開口部１１ａから塗布材Ｍを充填した後、当該押圧を解除して充填部１１を元の形状に形状復帰させると共に、形状復帰させた充填部１１に把持筒２０を一定量挿入して組み付け、充填した塗布材Ｍを前方へ移動させることにより画設される（詳しくは後述）。 Here, on the discharge port 16 side in the pen tip 10 (the front end side of the filling region 10x of the filling unit 11), it is appropriate to prevent the coating material M from being discharged from the discharge port 16 due to a temperature change or the like. A predetermined space H is formed. The predetermined space H is provided on the inner wall of the nib 10 and the front end surface of the coating material M. The predetermined space H presses the side of the filling portion 11 and deforms the filling portion 11 so that the volume in the filling portion 11 is reduced, and then the coating material M from the rear end opening portion 11a of the filling portion 11. Then, the pressure is released to restore the shape of the filling portion 11 to the original shape, and a predetermined amount of the gripping cylinder 20 is inserted into the filling portion 11 that has been restored to the shape. Is moved by moving to (details will be described later).
図５（ａ）は図１の塗布材押出容器における容器後部を構成する把持筒を示す側面図であり、図５（ｂ）は図５（ａ）のＶｂ−Ｖｂ線に沿う断面図である。図５に示すように、把持筒２０は、使用時に使用者が把持する部材であって、硬質の熱可塑性樹脂による射出成形で形成されている。把持筒２０は、前側が閉塞された段付き円筒状を呈し、挿入部２１と係合部２２と本体部２３とを前方から後方に向かってこの順で有している。把持筒２０の内周面は、外形形状に倣う段付き状を呈している。 FIG. 5A is a side view showing a gripping cylinder constituting the rear part of the coating material extruding container of FIG. 1, and FIG. 5B is a cross-sectional view taken along the line Vb-Vb of FIG. . As shown in FIG. 5, the gripping cylinder 20 is a member that is gripped by the user during use, and is formed by injection molding using a hard thermoplastic resin. The gripping cylinder 20 has a stepped cylindrical shape with the front side closed, and has an insertion portion 21, an engagement portion 22, and a main body portion 23 in this order from the front to the rear. The inner peripheral surface of the gripping cylinder 20 has a stepped shape following the outer shape.
挿入部２１は、ペン先１０の充填部１１に内挿されて嵌合されるものであり、充填部１１の基端部１５の内径より僅かに大きい外径を有している。係合部２２は、挿入部２１よりも大径の外径を有している。係合部２２の外周面には、中間部材３０と軸線方向に係合するものとして、径方向外側に突出し且つ周方向に沿って延在する環状凸部２４が設けられている。本体部２３は、係合部２２よりも大径の外径を有する。図１に示すように、本体部２３の後端側には、尾栓５０が内挿されて装着され、これにより、把持筒２０の後端側の開口が閉じられている。 The insertion portion 21 is inserted and fitted into the filling portion 11 of the nib 10 and has an outer diameter slightly larger than the inner diameter of the base end portion 15 of the filling portion 11. The engaging part 22 has an outer diameter larger than that of the insertion part 21. On the outer peripheral surface of the engaging portion 22, an annular convex portion 24 that protrudes radially outward and extends along the circumferential direction is provided to engage with the intermediate member 30 in the axial direction. The main body 23 has an outer diameter larger than that of the engaging portion 22. As shown in FIG. 1, a tail plug 50 is inserted and mounted on the rear end side of the main body portion 23, thereby closing the opening on the rear end side of the gripping cylinder 20.
このような把持筒２０は、その挿入部２１がペン先１０の充填部１１に後方から内挿されて嵌合されると共に、その係合部２２の前面が充填部１１の後端面に突き当たる状態とされる。これにより、把持筒２０がペン先１０に装着される。 In such a gripping cylinder 20, the insertion portion 21 is inserted and fitted into the filling portion 11 of the pen tip 10 from the rear, and the front surface of the engagement portion 22 hits the rear end surface of the filling portion 11. It is said. As a result, the gripping cylinder 20 is attached to the pen tip 10.
図６は、図１の塗布材押出容器の中間部材を示す縦断面図である。図６に示すように、中間部材３０は、筒状（環状）を呈し、把持筒２０と同様に、硬質の熱可塑性樹脂による射出成形で形成されている。中間部材３０における前端部の内周面には、ペン先１０の鍔部１８と係合するものとして、径方向内側に突出し且つ周方向に沿って延在する内周突部３１が設けられている。内周突部３１は、その径方向内側の端部が後方に張り出す鉤形状とされている。中間部材３０における後端部の内周面には、把持筒２０の環状凸部２４と係合するものとして、径方向内側に凹み且つ周方向に沿って延在する環状凹部３２が設けられている。 6 is a longitudinal sectional view showing an intermediate member of the coating material extruding container of FIG. As shown in FIG. 6, the intermediate member 30 has a cylindrical shape (annular shape), and is formed by injection molding with a hard thermoplastic resin, like the gripping cylinder 20. The inner peripheral surface of the front end portion of the intermediate member 30 is provided with an inner peripheral protrusion 31 that protrudes inward in the radial direction and extends along the peripheral direction, so as to be engaged with the flange portion 18 of the pen tip 10. Yes. The inner peripheral protrusion 31 has a bowl shape in which the radially inner end protrudes rearward. An annular recess 32 that is recessed radially inward and extending in the circumferential direction is provided on the inner peripheral surface of the rear end portion of the intermediate member 30 so as to be engaged with the annular protrusion 24 of the gripping cylinder 20. Yes.
このような中間部材３０は、図１に示すように、ペン先１０の充填部１１の後端部に外挿され、その内周突部３１がペン先１０の鍔部１８に係合される。このとき、鍔部１８が軟質材で形成されているところ、内周突部３１が鉤形状とされているため、内周突部３１が鍔部１８に埋入するようにして係合される。これにより、中間部材３０は、ペン先１０に軸線方向及び径方向に係合される。また、このとき、中間部材３０は、把持筒２０の挿入部２１と協働して充填部１１の後端部を挟み込む。 As shown in FIG. 1, such an intermediate member 30 is extrapolated to the rear end portion of the filling portion 11 of the nib 10, and the inner peripheral protrusion 31 is engaged with the collar portion 18 of the nib 10. . At this time, since the flange portion 18 is formed of a soft material, the inner peripheral protrusion portion 31 has a hook shape, and therefore the inner peripheral protrusion portion 31 is engaged so as to be embedded in the flange portion 18. . Accordingly, the intermediate member 30 is engaged with the pen tip 10 in the axial direction and the radial direction. At this time, the intermediate member 30 sandwiches the rear end portion of the filling portion 11 in cooperation with the insertion portion 21 of the gripping cylinder 20.
これと共に、中間部材３０は、その後端面が把持筒２０の本体部２３の前面に突き当たるまで当該把持筒２０の係合部２２に外挿され、その環状凹部３２に係合部２２の環状凸部２４が軸線方向に係合される。以上により、中間部材３０は、ペン先１０及び把持筒２０に装着され、ペン先１０及び把持筒２０を軸線方向に連結すると共に、ペン先１０を把持筒２０に対して挟持する。 At the same time, the intermediate member 30 is extrapolated to the engaging portion 22 of the gripping cylinder 20 until the rear end surface thereof abuts against the front surface of the main body 23 of the gripping cylinder 20, and the annular convex portion of the engaging portion 22 is inserted into the annular recess 32. 24 is engaged in the axial direction. As described above, the intermediate member 30 is mounted on the pen tip 10 and the gripping cylinder 20, connects the pen tip 10 and the gripping cylinder 20 in the axial direction, and clamps the pen tip 10 with respect to the gripping cylinder 20.
以上のように構成され図１に示す初期状態の塗布材押出容器１００にあっては、使用者によりキャップ４０及び栓１７が取り外された後、ペン先１０の充填部１１の側方が適宜押圧され、これにより、充填領域１０ｘに充填された塗布材Ｍが吐出口１６から吐出される。そして、当該塗布材Ｍが塗布対象に塗布されることとなる。 In the coating material extruding container 100 in the initial state configured as described above and shown in FIG. 1, the side of the filling portion 11 of the nib 10 is appropriately pressed after the cap 40 and the stopper 17 are removed by the user. Thus, the coating material M filled in the filling region 10x is discharged from the discharge port 16. Then, the coating material M is applied to the application target.
次に、上述の塗布材押出容器１００の製造方法を説明する。ここでは、塗布材Ｍの充填及び各構成の組付けについての一例を詳説する。図７（ａ）は図１の塗布材押出容器１００において塗布材Ｍの充填及び組付けを説明する図、図７（ｂ）は図７（ａ）の続きを示す図、図８（ａ）は図７（ｂ）の続きを示す図、図８（ｂ）は図８（ａ）の続きを示す図、図９（ａ）は図８（ｂ）の続きを示す図、図９（ｂ）は図９（ａ）の続きを示す図である。 Next, the manufacturing method of the above-mentioned coating material extruding container 100 will be described. Here, an example of filling the coating material M and assembling each component will be described in detail. 7A is a view for explaining filling and assembling of the coating material M in the coating material extrusion container 100 of FIG. 1, FIG. 7B is a diagram showing a continuation of FIG. 7A, and FIG. Is a diagram showing a continuation of FIG. 7 (b), FIG. 8 (b) is a diagram showing a continuation of FIG. 8 (a), FIG. 9 (a) is a diagram showing a continuation of FIG. 8 (b), and FIG. ) Is a diagram showing a continuation of FIG.
図７（ａ）に示すように、まず、ペン先１０の後端部に中間部材３０を外挿し、鍔部１８に内周突部３１を係合させて、ペン先１０に中間部材３０を装着し、これにより、容器中間体６０を得る。そして、充填治具７０の保持孔７１に容器中間体６０を前側から内挿し、容器中間体６０の後側の開口部が上方へ開放する立姿勢で当該容器中間体６０を保持する。 As shown in FIG. 7A, first, the intermediate member 30 is extrapolated to the rear end portion of the pen tip 10, the inner peripheral protrusion 31 is engaged with the collar portion 18, and the intermediate member 30 is attached to the pen tip 10. The container intermediate body 60 is obtained by mounting. The container intermediate body 60 is inserted into the holding hole 71 of the filling jig 70 from the front side, and the container intermediate body 60 is held in a standing posture in which the opening on the rear side of the container intermediate body 60 opens upward.
このとき、中間部材３０の前面は、充填治具７０の上面に突き当てられる。また、充填部１１における先端側の所定位置の側方には、充填治具７０における一対の押圧部７２が対向配置される状態となっている。一対の押圧部７２は、塗布部１３の短軸方向に沿う方向において互いに接近可能及び離間可能に設けられている。なお、図示する例では、一対の押圧部７２が配置される上記所定位置は、充填部１１において徐々に扁平となる軸線方向中央部から先端側の位置とされている。 At this time, the front surface of the intermediate member 30 is abutted against the upper surface of the filling jig 70. In addition, a pair of pressing portions 72 in the filling jig 70 are arranged opposite to each other at a predetermined position on the front end side in the filling portion 11. The pair of pressing parts 72 are provided so as to be able to approach and separate from each other in the direction along the short axis direction of the application part 13. In the illustrated example, the predetermined position where the pair of pressing portions 72 are arranged is a position on the distal end side from the axially central portion that gradually flattens in the filling portion 11.
続いて、図７（ｂ）に示すように、ペン先１０の充填部１１内に後側（上方側）からノズルＮｚを進入させる。これと共に、一対の押圧部７２を互いに接近するように可動し、当該押圧部７２の曲面状の先端部でもって充填部１１における側方の上記所定位置を挟み込んで押圧する。これにより、充填部１１内の容積が減少するように該充填部１１を変形させる。ここでの充填部１１の変形は、充填部１１内が完全に閉塞されてもよいし、略閉塞（隙間を有して閉塞）されてもよい。つまり、後段において充填された塗布材Ｍが流れ落ちない程度に塞がればよく、容積が減少すればよい。 Subsequently, as illustrated in FIG. 7B, the nozzle Nz is caused to enter the filling portion 11 of the nib 10 from the rear side (upper side). At the same time, the pair of pressing portions 72 are moved so as to approach each other, and the predetermined position on the side of the filling portion 11 is sandwiched and pressed by the curved tip portion of the pressing portion 72. Thereby, the filling part 11 is deformed so that the volume in the filling part 11 decreases. As for the deformation of the filling portion 11 here, the inside of the filling portion 11 may be completely closed or may be substantially closed (closed with a gap). That is, it is sufficient that the coating material M filled in the subsequent stage is blocked so that it does not flow down, and the volume is reduced.
続いて、図８（ａ）に示すように、充填部１１を変形させた状態において、例えば８０℃程度の温度に上昇させて溶解させた塗布材Ｍを、ノズルＮｚから充填部１１内に注入する。これにより、充填部１１内において押圧部７２で押圧して変形させた位置を起点に開口部側へ、当該塗布材Ｍを充填する。そして、図８（ｂ）に示すように、塗布材Ｍの充填を定量まで行った後、ノズルＮｚを上方へ移動させて充填部１１内から退避させる。ここでは、後段の把持筒２０の組付け時（図９（ｂ）参照）において挿入部２１と塗布材Ｍとの間に隙間が形成されない一定量以上、塗布材Ｍを充填する。塗布材Ｍについては、充填後直ちに（充填しながら）、又は充填後に所定冷却時間放置後に、充填部１１内にて自重等でずれ落ちない程度に固化される。 Subsequently, as shown in FIG. 8A, in a state where the filling portion 11 is deformed, the coating material M which is dissolved by being raised to a temperature of, for example, about 80 ° C. is injected into the filling portion 11 from the nozzle Nz. To do. As a result, the coating material M is filled into the opening portion side from the position where the pressure portion 72 is pressed and deformed in the filling portion 11. Then, as shown in FIG. 8B, after the filling of the coating material M is performed up to a fixed amount, the nozzle Nz is moved upward and retracted from the filling portion 11. Here, at the time of assembling the gripping cylinder 20 at the subsequent stage (see FIG. 9B), the coating material M is filled more than a certain amount so that no gap is formed between the insertion portion 21 and the coating material M. The coating material M is solidified immediately after filling (while filling) or after being left for a predetermined cooling time after filling so that it does not fall off due to its own weight in the filling portion 11.
その後、図９（ａ）に示すように、一対の押圧部７２を互いに離間するように可動し、充填部１１の側方に対する押圧を解除して、充填部１１を元の形状に形状復帰させる。これにより、ペン先１０内の吐出口１６側においてペン先１０の内壁及び塗布材Ｍの前端面で画設された仮空間Ｈ０を形成する（第１工程）。 Thereafter, as shown in FIG. 9A, the pair of pressing portions 72 are moved so as to be separated from each other, the pressing to the side of the filling portion 11 is released, and the filling portion 11 is restored to its original shape. . As a result, a temporary space H0 is formed on the discharge port 16 side in the pen tip 10 and defined by the inner wall of the pen tip 10 and the front end surface of the coating material M (first step).
続いて、図９（ａ）及び図９（ｂ）に示すように、形状復帰させた充填部１１に、後側から、尾栓５０が装着された把持筒２０の挿入部２１を一定量内挿して嵌合させる。このとき、環状凹部３２に環状凸部２４を軸線方向に係合させると共に、中間部材３０の前端部と挿入部２１とで充填部１１の後端部を挟み込む。これにより、容器中間体６０に把持筒２０が組み付けられる。その結果、充填した塗布材Ｍが前方に押し出されるように移動されると共に、ペン先１０の吐出口１６から仮空間Ｈ０の空気が排出され、この移動に応じて仮空間Ｈ０が適正に変化され、所定空間Ｈがペン先１０内の吐出口１６側に画設されることとなる（第２工程）。 Subsequently, as shown in FIGS. 9A and 9B, the insertion portion 21 of the gripping cylinder 20 to which the tail plug 50 is attached is placed within a certain amount from the rear side of the filling portion 11 whose shape has been restored. Insert and fit. At this time, the annular convex portion 24 is engaged with the annular concave portion 32 in the axial direction, and the rear end portion of the filling portion 11 is sandwiched between the front end portion of the intermediate member 30 and the insertion portion 21. Thereby, the gripping cylinder 20 is assembled to the container intermediate body 60. As a result, the filled coating material M is moved so as to be pushed forward, and air in the temporary space H0 is discharged from the discharge port 16 of the pen tip 10, and the temporary space H0 is appropriately changed according to this movement. The predetermined space H is provided on the discharge port 16 side in the pen tip 10 (second step).
なお、塗布材Ｍの硬度や充填条件等によって、押圧部７２による押圧の解除（充填部１１の形状復帰）に対する把持筒２０の挿入のタイミングは、適宜選択可能である。例えば、押圧部７２による押圧の解除前に把持筒２０の挿入を行ってもよいし、また、押圧部７２による押圧の解除を少し行った後に把持筒２０を挿入し、その後、当該押圧を完全に解除してもよい。 Depending on the hardness of the coating material M, filling conditions, and the like, the timing of inserting the gripping cylinder 20 with respect to the release of the pressing by the pressing portion 72 (returning the shape of the filling portion 11) can be selected as appropriate. For example, the gripping cylinder 20 may be inserted before releasing the pressing by the pressing portion 72, or the gripping cylinder 20 is inserted after releasing the pressing by the pressing portion 72 for a while, and then the pressing is completely performed. You may cancel it.
図１０は、上述の製造方法により製造された図１の塗布材押出容器１００を示すＸ線写真図である。図１０に示すように、本実施形態の塗布材押出容器１００では、ペン先１０内の吐出口１６側において、充填部１１を押圧し変形させた状態で塗布材Ｍを充填した後に充填部１１を形状復帰させ、把持筒２０を充填部１１に組み付けて当該塗布材Ｍを移動させて成る所定空間Ｈが、充填部１１の内壁及び塗布材Ｍの前端面で画設されることを確認できる。 FIG. 10 is an X-ray photograph showing the coating material extruding container 100 of FIG. 1 manufactured by the above-described manufacturing method. As shown in FIG. 10, in the coating material extruding container 100 of the present embodiment, the filling unit 11 is filled after the coating material M is filled in a state where the filling unit 11 is pressed and deformed on the discharge port 16 side in the pen tip 10. It is possible to confirm that the predetermined space H formed by assembling the gripping cylinder 20 to the filling portion 11 and moving the coating material M is provided on the inner wall of the filling portion 11 and the front end surface of the coating material M. .
以上、本実施形態では、ペン先１０内の吐出口１６側において、容易且つ適正に形成された空間として所定空間Ｈを有する塗布材押出容器１００を実現することができる。すなわち、例えば、ペン先１０が軟質材で成形されているのを利用して、上述した塗布材Ｍの充填及び組付けを実施し、適正化された所定空間Ｈをペン先１０内の吐出口１６側に容易に画設することができる。この所定空間Ｈによれば、充填部１１における塗布材Ｍの充填量を必要十分に確保させつつ、温度変化等により吐出口１６から塗布材Ｍが自然漏出するのを防ぐことが可能となる。 As described above, in the present embodiment, it is possible to realize the application material extruding container 100 having the predetermined space H as the easily and properly formed space on the discharge port 16 side in the nib 10. That is, for example, using the fact that the nib 10 is formed of a soft material, the above-described filling and assembling of the coating material M is performed, and the optimized predetermined space H is discharged to the discharge port in the nib 10. It can be easily set on the 16 side. According to the predetermined space H, it is possible to prevent the coating material M from naturally leaking from the discharge port 16 due to a temperature change or the like while ensuring a necessary and sufficient amount of the coating material M to be filled in the filling portion 11.
本実施形態は、充填部１１における後端部の外周面に鍔部１８が設けられ、中間部材３０における前端部の内周面に内周突部３１が設けられている。そして、鍔部１８及び内周突部３１は、互いに係合している。よって、ペン先１０が把持筒２０から外れるのを防ぐことが可能となる。 In the present embodiment, the flange portion 18 is provided on the outer peripheral surface of the rear end portion of the filling portion 11, and the inner peripheral protrusion 31 is provided on the inner peripheral surface of the front end portion of the intermediate member 30. And the collar part 18 and the inner peripheral protrusion 31 are engaged with each other. Therefore, it is possible to prevent the pen tip 10 from being detached from the gripping cylinder 20.
本実施形態において、ペン先１０における充填部１１の後端部は、把持筒２０の挿入部２１と中間部材３０の前端部とにより、径方向に挟み込まれている。よって、ペン先１０が把持筒２０から外れるのを一層防ぐことが可能となる。また、ペン先１０の後部内径が挿入部２１に密着され、これらの間の気密性を確実に確保することができる。また、充填部１１に挿入部２１を挿入する際、この挿入部２１の外周面に軸線方向に延びる縦溝２６（図５参照）が形成されていることから、一定区間において当該縦溝２６を介して充填部１１の後部の空気を流通させて排出することが可能となる。 In the present embodiment, the rear end portion of the filling portion 11 in the nib 10 is sandwiched between the insertion portion 21 of the gripping cylinder 20 and the front end portion of the intermediate member 30 in the radial direction. Therefore, it is possible to further prevent the pen tip 10 from being detached from the gripping cylinder 20. In addition, the rear inner diameter of the pen tip 10 is in close contact with the insertion portion 21, and airtightness between them can be reliably ensured. Further, when the insertion portion 21 is inserted into the filling portion 11, the longitudinal groove 26 (see FIG. 5) extending in the axial direction is formed on the outer peripheral surface of the insertion portion 21. It becomes possible to circulate and discharge the air in the rear part of the filling part 11 through.
また、本実施形態において、ペン先１０は、タイプＡデュロメータによるデュロメータ硬さが８０よりも小さい軟質のゴム、又は、熱可塑性エラストマーによる弾性体で形成されている。一方、中間部材３０及び把持筒２０は、硬質の熱可塑性樹脂で形成されている。このような材料でペン先１０、中間部材３０及び把持筒２０を形成することにより、ペン先１０が外れるのを防ぐ上記効果は顕著となる。 In the present embodiment, the nib 10 is formed of a soft rubber having a durometer hardness of less than 80 by a type A durometer, or an elastic body made of a thermoplastic elastomer. On the other hand, the intermediate member 30 and the gripping cylinder 20 are formed of a hard thermoplastic resin. By forming the pen tip 10, the intermediate member 30, and the gripping cylinder 20 with such a material, the above-described effect of preventing the pen tip 10 from coming off becomes remarkable.
下記結果は、塗布材押出容器１００の引張り強度測定値の材質比較結果を示している。下記結果において、ＮＢＲにおける数値はデュロメータ硬さを示している。ＡＢＳはＡＢＳ樹脂（アクリロニトリル・ブタジエン・スチレンの共重合合成樹脂）である。引張り強度における各数値は、引張力を加えたときに分解されずに（各部品が外れずに）耐え得る強度であって、ニュートンを示している。 The following results show the material comparison results of the tensile strength measurement values of the coating material extrusion container 100.

上記強度測定値の材質比較結果に示すように、本実施形態に係る実施例１（ペン先１０をデュロメータ硬さ７０のＮＢＲとし、中間部材３０及び把持筒２０をともにＡＢＳ樹脂とした場合）では、比較例１〜３（ペン先１０をデュロメータ硬さ７０のＮＢＲとし、中間部材３０及び把持筒２０をともにＡＢＳ樹脂としない場合）に比べ、引張り強度が高く各部品が外れ難いことを確認することができる。これにより、例えばペン先１０が軟質材で形成される場合にはペン先１０が外れ易くなるところ、本実施形態の塗布材押出容器１００では、ペン先１０が外れるのを防ぐことができるという上記作用効果が顕著であるのを確認することができる。 As shown in the material comparison result of the intensity measurement value, in Example 1 according to the present embodiment (when the nib 10 is NBR with durometer hardness 70 and the intermediate member 30 and the gripping cylinder 20 are both ABS resin) Compared with Comparative Examples 1 to 3 (when the nib 10 is made of NBR with durometer hardness 70 and the intermediate member 30 and the gripping cylinder 20 are not made of ABS resin), it is confirmed that the tensile strength is high and each component is difficult to come off. be able to. Thereby, for example, when the nib 10 is formed of a soft material, the nib 10 is easily detached. However, in the coating material extruding container 100 of the present embodiment, the nib 10 can be prevented from coming off. It can be confirmed that the effect is remarkable.
ちなみに、塗布材押出容器１００では、塗布部１３が扁平状とされていることから、使用者が塗布材押出容器１００を用いて塗布材Ｍを塗布するに際して、塗布部１３にコシを与えることができ、例えば塗布材Ｍのラインを安定して引くことが可能となる。また、塗布材押出容器１００は、塗布材Ｍを容器から押し出すための押出機構を別途に備えずに構成されており、押出機構によらずに塗布材Ｍを塗布可能なものとなっている。これにより、塗布材押出容器１００の簡易化、製造容易化及び低コスト化が可能となる。 Incidentally, in the coating material extruding container 100, since the coating part 13 is flat, when the user applies the coating material M using the coating material pushing container 100, the coating part 13 may be stiff. For example, the line of the coating material M can be stably drawn. Further, the coating material extrusion container 100 is configured without a separate extrusion mechanism for extruding the coating material M from the container, and can apply the coating material M without depending on the extrusion mechanism. As a result, the coating material extruding container 100 can be simplified, easily manufactured, and reduced in cost.
以上、本発明の実施形態について説明したが、本発明は、上記実施形態に限られるものではなく、各請求項に記載した要旨を変更しない範囲で変形し、又は他のものに適用したものであってもよい。 As mentioned above, although embodiment of this invention was described, this invention is not restricted to the said embodiment, It deform | transforms in the range which does not change the summary described in each claim, or applied to another thing. There may be.
例えば上記実施形態では、充填治具７０を用い、１つの塗布材押出容器１００について塗布材Ｍを充填したが、複数の容器中間体６０を充填対象とする充填治具を用い、複数の塗布材押出容器１００について同時に塗布材Ｍを充填して組み付けてもよい。上記実施形態では、充填部１１の側方に対する押圧を解除して充填部１１を元の形状に形状復帰させているが、充填部１１の側方に対する押圧を解除しなくてもよいし、また、充填部１１を元の形状に形状復帰させなくともよい。また、形状復帰は、完全に形状が戻る場合だけでなく、一部の形状が戻る場合も含んでいる。 For example, in the above-described embodiment, the filling material 70 is filled with the coating material M using the filling jig 70, but a plurality of coating materials are used using the filling jig for filling a plurality of container intermediates 60. The extrusion container 100 may be simultaneously filled with the coating material M and assembled. In the above embodiment, the pressure on the side of the filling portion 11 is released to restore the shape of the filling portion 11 to the original shape. However, the pressure on the side of the filling portion 11 may not be released, The filling portion 11 does not have to be restored to its original shape. Further, the shape recovery includes not only the case where the shape is completely restored but also the case where a part of the shape is restored.
