Description

  In the present invention, a viscous liquid, particularly a moisture-curable adhesive composition or an oxygen-curable adhesive composition is housed in a flexible bag or container and pressure is applied from the outside. The plastic container, long channel member, application device, cap with cap, and sealed state that are effectively used when the bag or container is deformed and reduced to discharge the viscous liquid inside and apply. The present invention relates to a plastic container and a packed plastic container.

  Conventionally, in a coating apparatus that applies a moisture curable adhesive or an oxygen curable adhesive, the adhesive hardens when it comes into contact with the air. Since inconveniences such as causes occur, it is necessary to apply the adhesive in a state where it is not in contact with air.

  A general discharge mode of the viscous liquid in this type of conventional coating apparatus will be described with reference to FIGS. In FIG. 25 to FIG. 27, reference numeral 100 denotes a conventional coating apparatus, and a pressurized tank 102 and compressed air supply means (not shown) for supplying compressed air into the pressurized tank 102 via an air supply pipe 104. A plastic container 106 installed in the pressurized tank 102, a liquid feeding pipe means 110 having one end communicating with the opening 108 of the plastic container 106, and the other end of the liquid feeding pipe means 110. Application nozzle means (not shown) is provided. A viscous liquid 112 is filled in the plastic container 106. FIG. 25 shows a state in which the viscous liquid 112 is filled in the plastic container 106, and FIG. 26 shows that the plastic container 106 is pressurized from the outside to be deformed and reduced, and the viscous liquid 112 is discharged to the outside. FIG. 27 shows a final state where the plastic container 106 is further pressurized and the central portions come into contact with each other and the viscous liquid 112 is not discharged to the outside. On the other hand, there is a case where the liquid feeding means 110 is used by extending to the inside of the plastic container 106 through the opening 108 of the plastic container 106. In this case, the liquid feeding means 110 is repeated. In order to use, when the liquid feeding process is completed, the viscous liquid is taken out with the tip portion of the liquid feeding pipe means 110 attached, so that the sticky viscous liquid is scattered around the coating device. , Will cause dirt.

  Proposals have also been made for devices that apply liquids that dislike contact with air. For example, as an apparatus for storing a viscous liquid or the like in a flexible bag or container and applying pressure from the outside to deform and reduce the bag or container and discharge the internal viscous liquid to the outside and apply it , "Deformable airtight container filled with adhesive, pressure tank containing the airtight container, hose connecting the discharge unit and the airtight container provided outside the pressure tank, pressure device for the pressure tank In the adhesive applicator consisting of the following, the sealed container is filled with water-based adhesive, the tip of the hose connected to the sealed container is connected to the spray gun, and the outer wall surface of the hose attachment part of the sealed container is deformed when contracted. An adhesive application device provided with a ridge-shaped reinforcing part to be regulated "(Claim 1 of Patent Document 1) is known. In the adhesive coating apparatus of Patent Document 1, in this type of conventional coating apparatus, as described in Paragraph 0004 of Patent Document 1, the adhesive is discharged smoothly at the beginning, Restrict the deformation when shrinking to the outer wall surface of the hose attachment part of the sealed container for the case where the film body in the vicinity of the hose attachment part of the bag closed the connection part with the hose and it became impossible to discharge The problem is solved by providing a hook-shaped reinforcing portion. Although the device of Patent Document 1 is certainly effective for eliminating the discharge failure near the hose attachment portion, other bag or container portions, for example, the central portion of the bag or container as shown in FIG. It does not work well for accidents that prevent discharge.

  Further, as a coating apparatus, “a fluid that is connected to the liquid container according to any one of claims 1 to 7 and a liquid discharge port of an inner container that constitutes the container and introduces a pressure fluid into the inside thereof. A coating apparatus comprising: introduction means; and means for spraying liquid to be coated which is connected to the pump unit and pressurized and delivered by the pump unit. Item 8) is also known. And in this coating apparatus, as a container for liquid, “a container for storing liquid that dislikes contact with air and discharging the liquid without invading it as much as possible when discharging the liquid” An inner container provided with a liquid discharge port connected to a pump unit that discharges the liquid in a flexible bag shape whose volume can be freely changed, and a state in which the inner container is accommodated without changing in volume. And an outer container into which the pressure fluid is introduced inside the inner container in a sealed state, and the inner container is discharged as the liquid contained in the inner container is discharged. The air region formed inside is pushed and narrowed by the pressure fluid introduced into the outer container, so that the liquid is discharged from the inner container so that air does not enter the inner container as much as possible. Liquid characterized by Container. "Discloses (claim 1 of Patent Document 2). Further, in Patent Document 2, “the suction hose 6 connected to the paint discharge port 5 is extended inside the inner container 1 and the length of the suction hose 6 is expanded. It is slightly longer than the height of the inner container 1 when it is in the shape of a cube, so that the tip of the suction hose 6 is always in contact with the bottom surface of the inner container 1 and the water-based paint contained in the inner container 1 All P can be sucked in "(Patent Document 2, paragraph 0025), which teaches the use of the suction hose 6. In the apparatus of Patent Document 2, the suction hose 6 is used repeatedly. When the liquid feeding process is finished, the suction hose 6 is taken out while the viscous liquid is attached to the tip portion of the suction hose 6. It is the same as in the case of Patent Document 1 that the viscous liquid (water paint in Patent Document 2) is scattered around the coating device and causes dirt, and the suction hose 6 is sucked. Since the mouth is only formed at the tip of the suction hose 6, there is an accident that the suction of the viscous liquid is not performed if the suction mouth is blocked by contact with the wall of the inner container 1 or the like. There is a disadvantage that occurs.

It is characterized by. It is preferable that the long channel portion is a tubular body having one or more channel holes formed in the side surface.

  The coating apparatus of the present invention includes a pressurized tank, compressed air supply means for supplying compressed air into the pressurized tank, a plastic container of the present invention installed in the pressurized tank, and an opening of the plastic container A liquid feed pipe means whose one end communicates with the part, and an application nozzle means connected to the other end of the liquid feed pipe means. When compressed air is supplied into the pressurized tank, The plastic container installed in the tank is pressurized and crushed to discharge the viscous liquid therein from the plastic container through the elongated channel member, and then through the liquid feeding means. After the viscous liquid is sprayed from the coating nozzle means and applied to a predetermined site, and the plastic container body is crushed by pressurization and all the viscous liquid filled therein is pressurized and discharged. , Crushed Characterized in that the plastic container body to the elongated channel member were both to be a waste and.

  In the coating apparatus according to the present invention, the elongated channel member is detachably attached to the opening of the plastic container body and has an upper end attachment portion having a liquid discharge opening at the center, and an interior of the plastic container body. An elongated channel portion integrally attached to the mounting portion so as to extend to the mounting portion, and the elongated channel member is configured to be detachably attached to the opening. The upper end mounting portion of the elongated channel member is fitted into the opening of the plastic container body, the liquid feeding means is inserted into the liquid discharge port of the upper end mounting portion, and the liquid is inserted by the sealing insertion means. It is preferable that the pipe feeding means is inserted into the liquid discharge port in a sealed state.

  The sealing insertion means has a lower surface shape corresponding to the upper surface shape of the upper end mounting portion of the elongated channel member, and forms a receiving step portion on the lower upper surface and a male screw portion on the upper outer surface. And a fixing member having an insertion opening at the center, and a through hole that contacts the receiving stepped portion at the center of the circular plate, and on the inner surface side of the annular side wall that is suspended from the peripheral edge of the circular plate A cap member with a through-hole formed with a female screw portion that can be screwed into a male screw portion formed on the outer surface of the cylindrical side wall of the opening of the plastic container body, and a center hole formed in the center portion and the center hole A fastening member having a female screw portion formed on the inner surface thereof, wherein the fixing member is brought into contact with the upper surface of the upper end mounting portion of the elongated channel member, and the center hole of the fastening member and the fixing member The liquid feed pipe means is connected to the upper end attachment portion of the long channel member through the insertion port of The cap member with a through hole is inserted into the male screw portion of the cylindrical side wall of the opening of the plastic container body with the through hole of the cap member with the through hole being in contact with the receiving step portion. The female screw part is screwed and screwed, and then the liquid screw part is screwed by screwing the female screw part on the inner surface of the center hole of the fastening member to the male screw part on the upper outer surface of the fixing member. It is preferable that the pipe feeding means is inserted into the liquid discharge port of the upper end attachment portion of the long channel member in a sealed state.

  A first aspect of the cap with an inner stopper of the present invention is a cap with an inner stopper used to seal the opening of the plastic container body of the plastic container of the present invention, and is suspended from the peripheral edge of the circular plate. A cap body having a female screw portion that can be screwed into a male screw portion formed on the outer surface of the cylindrical side wall of the opening of the plastic container main body on the inner surface side of the annular side wall; and And an inner plug member suspended from the liquid discharge port of the long channel member.

  According to a second aspect of the cap with an inner plug of the present invention, as a more preferable structure, as the inner plug member, a cylindrical hanging portion that is suspended at the center of the lower surface of the circular plate, and a lower end of the cylindrical hanging portion And a flexible cylindrical fitting portion suspended from a circular peripheral edge portion. The flexible cylindrical fitting portion has a very high flexibility because the lower end portion is a free end. In the case of a structure in which only a cylindrical hanging part is provided as an inner plug member when the inner plug member fitted to the liquid discharge port of the long channel member is extracted from the liquid discharge port, the upper part of the cylindrical hanging part Is fixed, and its lower end is hard and has very little mobility, so that the cylindrical hanging part is tightly fitted to the liquid discharge port and is difficult to come off along with the long channel member. Inconvenience may occur. On the other hand, when it has a structure in which a cylindrical fitting portion having flexibility is provided at the lower end of the columnar hanging portion as an inner plug member, the inner plug member in a state of being fitted to the liquid discharge port of the long channel member When the liquid is removed from the liquid discharge port of the long channel member, the liquid is not tightly fitted to the liquid discharge port by the flexible action of the cylindrical fitting portion. There is an advantage that it can be easily extracted from the discharge port.

  The sealed plastic container according to the present invention is a plastic container according to the present invention in which the viscous liquid is filled in the plastic container body and the opening of the plastic container body is closed with a cap. It is characterized by being housed in a moisture or oxygen-impermeable bag formed of a material and sealed. As the cap, the cap with an inner plug of the present invention described above is preferably used. It is preferable that the cap with an inner plug of the present invention described above is used as the cap, and the liquid discharge port of the elongated channel member is closed with the inner plug member. As the moisture or oxygen impermeable material, a multilayer sheet-like material containing at least one aluminum foil layer is preferably used.

  The packaged plastic container of the present invention is characterized in that the above-described sealed plastic container of the present invention is packed with cardboard to form a packaged state.

  According to the plastic container of the present invention, the opening is opened and the inside is filled with a viscous liquid, in particular, a moisture-curable adhesive composition or an oxygen-curable adhesive composition. In a plastic container in which a flexible plastic container body is crushed by pressure and the viscous liquid is pressurized and discharged from the opening, the opening is extended to the inside of the plastic container body. A long flow path member is attached, and the long flow path member becomes a flow path for the viscous liquid when the viscous liquid is discharged under pressure, and the viscous liquid is removed when the plastic container body is crushed. After the plastic container main body is crushed by pressurization and all the viscous liquid stored therein is pressurized and discharged, When the tube member such as a suction hose is repeatedly used by discarding both the crushed plastic container main body and the elongated channel member, the viscous liquid attached to the tube member, particularly the moisture curing type It is possible to achieve an effect that it is possible to eliminate the fact that the curable composition having the above adhesive property or the curable composition having the oxygen curable adhesive property is scattered to cause surrounding stains.

  The elongated channel member of the present invention is used by being attached to the opening of the plastic container body in the plastic container of the present invention, or in the opening of a plastic container that presses and discharges the liquid contents by existing pressurization. By mounting and using, the effect that it becomes possible to efficiently press and discharge the liquid contents of the plastic container without leaving a residual liquid is achieved.

  According to the coating apparatus of the present invention, since the plastic container of the present invention is arranged, it is possible to efficiently press and discharge the liquid contents without leaving a residual liquid, and thus the coating efficiency is improved and The content of viscous liquid, especially moisture-curing adhesive curable composition or oxygen-curing adhesive curable composition can be prevented from scattering and causing surrounding dirt. The effect of being able to be achieved can be achieved.

  When a plastic container filled with a viscous liquid is stored or transported to a site where a coating operation is performed, the opening of the plastic container is usually closed with a cap. In this case, when a cap having a general structure is used to close the opening of the plastic container having the structure of the present invention and the liquid discharge port of the long channel member, the viscous liquid is discharged when the cap is removed. While adhering to the inner surface portion of the circular plate in contact with the outlet, it is located up to the upper end portion of the inner peripheral surface of the elongated channel member. From this state, the liquid feeding means is communicated with the elongated channel member, and the fixing member, the cap member with a through hole, and the fastening member are attached to perform the pressure discharge operation of the viscous liquid, and then the pressure discharge operation. When the liquid feeding pipe means, the fixing member, the through-hole cap member and the clamping member are removed, the viscous liquid adheres to the outer peripheral surface of the lower end taper portion of the cylindrical base of the fixing member and becomes dirty. When this adhering viscous liquid hardens over time, it becomes difficult to fit the lower end taper portion and the upper end taper portion of the long channel member, or it becomes impossible to fit when it becomes severe, which is inconvenient for next use. Or the disadvantage of becoming unusable.

  In order to solve the problems caused by the use of a cap having a general structure as described above, the present inventor has formed a cylindrical side wall of the opening of the plastic container body on the inner surface side of an annular side wall suspended from the peripheral edge of the circular plate. A cap main body formed with a female screw portion that can be screwed into a male screw portion formed on the outer surface of the circular plate, and a vertical center of the circular plate so as to be fitted to the liquid discharge port of the long channel member. A cap with an inner stopper according to a first aspect having an inner stopper member provided is proposed. When the cap with the inner plug of the first aspect of the present invention is used to close the opening of the plastic container having the structure of the present invention and the liquid discharge port of the long channel member, the inner plug member becomes the long channel member. The upper end portion of the through flow path is fitted, and the viscous liquid does not enter the upper end portion of the through flow path, and the viscous liquid does not adhere to the upper end portion of the through flow path. Therefore, when the cap with the inner plug is removed, there is no viscous liquid in the upper end portion of the through flow path, and no dirt is generated, and a clean state is obtained.

  From this state, the liquid feeding means is communicated with the elongated channel member, and the fixing member, the cap member with a through hole, and the fastening member are attached to perform the pressure discharge operation of the viscous liquid, and then the pressure discharge operation. When the liquid feeding pipe means, the fixing member, the through-hole cap member and the tightening member are removed, there is no viscous liquid on the outer peripheral surface of the lower end taper portion of the cylindrical base of the fixing member, and clean. It is a state. Therefore, there is an advantage that the next use can be used without any inconvenience as in the first use.

  Further, the present inventor has a more preferable structure with a cap with a plug, as the plug member, a columnar hanging portion that is suspended from the center of the lower surface of the circular plate, and a lower-end circular periphery of the columnar hanging portion. The structure of the cap with an inner stopper of the 2nd aspect which has a flexible cylindrical fitting part hung by the part is proposed. When the cap with the inner plug of the second aspect of the present invention is used for closing the opening of the plastic container having the structure of the present invention and the liquid discharge port of the long channel member, the inner plug member becomes the long channel member. The upper end portion of the through flow path is fitted, and the viscous liquid does not enter the upper end portion of the through flow path, and the viscous liquid does not adhere to the upper end portion of the through flow path. Therefore, when the cap with the inner plug is removed, there is no viscous liquid in the upper end portion of the through flow path, and no dirt is generated, and a clean state is obtained.

From this state, the liquid feeding means is communicated with the elongated channel member, and the fixing member, the cap member with a through hole, and the fastening member are attached to perform the pressure discharge operation of the viscous liquid, and then the pressure discharge operation. When the liquid feeding pipe means, the fixing member, the through-hole cap member and the tightening member are removed, there is no viscous liquid on the outer peripheral surface of the lower end taper portion of the cylindrical base of the fixing member, and clean. It is a state. Therefore, there is an advantage that the next use can be used without any inconvenience as in the first use.
In addition, as described above, when the inner plug member fitted to the liquid discharge port of the long channel member is removed from the liquid discharge port, only the cylindrical hanging portion is provided as the inner plug member. The upper part of the cylindrical drooping part is fixed, and the lower end part is hard and has very little mobility, so that the cylindrical drooping part tightly fits into the liquid discharge port and is difficult to come off. Inconveniences such as coming out together with the flow path member may occur. However, in the cap with an inner plug of the second aspect of the present invention, a cylindrical shape having flexibility at the lower end of the columnar hanging portion as the inner plug member The flexible cylindrical fitting portion has a very low flexibility because the flexible cylindrical fitting portion has a free end at the lower end portion. When removing the fitted plug member from the liquid outlet of the long channel member Never would fit tightly to the fluid outlet by a flexible action of the tubular fitting portion, there is advantage that the variation at the time of molding can be drawn off easily from somewhat the fluid outlet also be present.

  When a plastic container filled with a viscous liquid is stored or transported to a site where a coating operation is performed, the opening of the plastic container is usually closed with a cap. However, since the plastic container main body of the plastic container is formed of a polyethylene film (water, moisture and oxygen pass through), moisture, moisture and oxygen present in the air will enter the plastic container. No problem occurs when left in the air for a short time, but if left in the air for a long time, the curing reaction proceeds in the case of moisture and oxygen-curing viscous liquid due to moisture, moisture, and oxygen that has entered the inside. Inconvenience occurs.

  The sealed plastic container of the present invention is accommodated in, for example, a moisture or oxygen-impermeable bag body made of a multilayer sheet-like material containing at least one aluminum foil layer that is impermeable to moisture, moisture and oxygen. Since the plastic container of the present invention is in a sealed state, the viscous liquid filled in the plastic container does not come into contact with moisture or oxygen in the air, and it is unforeseen that it hardens in contact with moisture or oxygen. The situation is avoided.

  The packaged plastic container of the present invention is a protective package of the above-described sealed plastic container of the present invention with corrugated cardboard, and the sealed plastic container or the moisture or oxygen-impermeable bag breaks in the middle of the sealed plastic container. There is an advantage that it can be safely transported to the site where the coating operation is performed in a protective packaging state so as not to be damaged.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. 1 to 23 and FIGS. 28 to 42 in the accompanying drawings. Needless to say, various modifications are possible.

  FIG. 1 is a cross-sectional explanatory view showing an embodiment in which a plastic container according to the present invention is installed in a pressurized tank, and shows a state where a viscous liquid is filled in a plastic container body. In FIG. 1, reference numeral 10 denotes a plastic container of the present invention, which has a plastic container body 12. The plastic container body 12 is formed of a plastic material having flexibility so that it can be crushed by pressurization, for example, polyethylene or polypropylene. However, soft polyethylene is used because of its flexibility, economy, and ease of molding. Especially suitable. An opening 14 is opened in the upper part of the plastic container body 12. The plastic container main body 12 can be filled with a viscous liquid 16. When the viscous liquid 16 is filled in the plastic container body 12, when pressure is applied from the outside of the plastic container body 12, the plastic container body 12 is deformed and reduced by pressurization, and finally The crushed and viscous liquid 16 is pressed and discharged from the opening 14 via the liquid feeding pipe means 20. Teflon (registered trademark) is suitable for the material of the liquid feeding means 20.

As the viscous liquid 16, a viscous liquid having a viscosity of 5 to 500 Pa · s / 23 ° C., preferably 10 to 100 Pa · s / 23 ° C., more preferably 15 to 60 Pa · s / 23 ° C. is applicable. As the viscous liquid 16, a curable composition having adhesiveness is particularly preferably used. Examples of the curable composition having adhesiveness include an adhesive, a sealing material, and a potting material. The tack-free time (TFT) of the viscous liquid is suitably in the range of 0 to 60 minutes, preferably 0 to 10 minutes, more preferably 0 to 3 minutes. In the present invention, when applied to a viscous liquid having a viscosity and tack-free time in the above range, a tremendous effect is achieved in that it is less likely to become dirty as compared with the conventional product.
The curable composition having adhesiveness is preferably a room temperature curable curable composition that can be cured at room temperature by touching air such as a moisture curable type or an oxygen curable type, in particular, a modified silicone type, a polyurethane type, A moisture-curing adhesive such as silicone is more preferably used.

  Reference numeral 18 denotes an elongate channel member, which is attached to the opening 14 so as to extend into the plastic container main body 12 and flows when the viscous liquid 16 is pressurized and discharged. It is comprised so that it may have the function to ensure formation. The long channel member 18 only needs to act so as to form a viscous liquid channel, and various forms are possible as will be described later. In the illustrated example of FIG. A long flow passage portion 26a composed of a long cylindrical tube body 30a integrally attached to the attachment portion 24 so as to extend into the plastic container body 12. A structure in which one or a plurality of (in the illustrated example, plural) flow path holes 32 are opened on the side wall of the cylindrical tube body 30a is shown. Reference numeral 28 denotes a lower end opening end of the elongated channel member 18.

  The material of the long channel member is not particularly selected as long as it can be molded, but from the viewpoint of easy fitting, a flexible plastic material such as polyethylene, polypropylene, nylon, fluorine rubber, silicone cone rubber, EPDM, Since SBS, SIS, SEBS, etc. are good and injection molding is easy and inexpensive, olefin resins such as polyethylene and polypropylene are better, especially soft polyethylene that is soft and inexpensive. The long channel member has a simple mold structure when the shape of the long channel portion is appropriately selected when the upper end mounting portion is formed of a simple cylindrical (rotary body) structure. By combining them, a long channel member can be manufactured at low cost.

  In FIG. 1, reference numeral 22 denotes a pressurized tank, which is configured so that pressurized air is introduced into the inside through a compressed air supply means (not shown) through an air supply pipe 21. In use, the plastic container 10 of the present invention is used in a state where it is installed in the pressurized tank 22, and as shown in FIG. To 0.6 MPa), the plastic container body 12 is pressurized and deformed to discharge the internal viscous liquid 16 from the opening 14 through the liquid feeding means 20, and finally, FIG. As shown in FIG. 3, the plastic container body 12 is completely crushed by pressurization and works to discharge all the viscous liquid 16 contained therein. Then, the completely crushed plastic container 10 as shown in FIG. 3, in other words, the plastic container body 12 and the elongated channel member 18 remain in a crushed state without being reused. Disposal is possible. For example, when the long channel member 18 is reused, the long channel member 18 after use is pulled out from the plastic container main body 12 and used. The viscous liquid adhering to the member 18 scatters around and causes dirt, but in the present invention, the elongate flow path member 18 can be discarded as it is together with the plastic container main body 12, so that such dirt is generated. There is an advantage that there is nothing.

  4A and 4B are explanatory views showing a first example of a long channel member used in the plastic container of the present invention, where FIG. 4A is a top view and FIG. 4B is a cross-sectional view. FIG. 5 is a drawing showing a long channel member similar to FIG. 4, (a) is a perspective explanatory view showing the whole, and (b) is a perspective explanatory view showing only the long portion with the upper end omitted. . 4 and 5, the elongate flow path member 18 is attached to the opening 14 of the plastic container body 12 and has an upper end mounting portion 24 having a liquid discharge port 23 opened in the center. And an elongated channel portion 26a integrally attached to the mounting portion 24 so as to extend into the plastic container body 12 and having a through channel 25a opened at the center.

  The upper end mounting portion 24 has an inner peripheral wall 27 that forms the liquid discharge port 23 and an outer peripheral wall 31 that is provided at a position spaced apart from the inner peripheral wall 27 by a support wall 29 with a predetermined interval. An inner diameter of the inner peripheral wall 27 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 33 inclined inward. An upper end portion of the outer peripheral wall 31 is bent outward to form an outer peripheral step portion 35. The elongate flow path member 18 can be detachably attached to the opening 14 by fitting the outer peripheral step 35 to the outer peripheral edge of the opening 14 of the plastic container body 12.

  Since the opening 14 of the plastic container main body 12 is formed in a wide mouth, if the elongated channel member 18 is detachably attached to the opening 14, the elongated channel member 18 is provided. When the viscous liquid 16 is injected into the plastic container main body 12 without fitting, the viscous liquid 16 can be injected with a margin from the wide opening 14, and after the injection, The procedure for fitting the member 18 into the opening 14 has the advantage that the viscous liquid can be injected without any trouble. On the other hand, if the elongate flow path member 18 is attached to the opening 14 in advance, the viscous liquid 16 becomes viscous via the liquid discharge port 23 opened narrowly in the elongate flow path member 18. The liquid 16 is injected, and the injection operation has a disadvantage that the injection operation is hindered as compared with the case where the injection is performed using the wide opening 14.

  The long channel member 18 acts so that the viscous liquid 16 remaining inside the plastic container body 12 can be discharged or discharged even when the plastic container body 12 is finally crushed. Is essential. In the example of FIGS. 1 to 5, one or a plurality of the elongated channel portions 26 a of the elongated channel member 18 are provided on the side wall of the elongated cylindrical tube body 30 a having the lower end as the opening end portion 28 (illustrated example). In the figure, a structure in which a plurality of flow path holes 32 are opened is shown. According to the elongate flow path member 18 having this structure, even if the plastic container body 12 is crushed, the open end 28 at the lower end and one or the plurality of flow path holes 32 remain open. Thus, it is possible to work so as to ensure a discharge flow path for the viscous liquid 16. In the above configuration, since the flow passage hole 32 described above is opened, the viscous liquid 16 first passes through the flow passage hole 32 and then passes through the liquid discharge port 23 and the opening portion 14 to be finally obtained. The liquid is discharged under pressure through the liquid feed pipe means 20. It should be noted that if the flow path hole 32 is sufficiently opened, the opening of the lower end opening end portion 28 is not essential, and it is needless to say that a sufficient flow path can be secured even when the flow path hole 32 is closed.

  Even when the plastic container main body 12 is finally crushed, the structure of the elongated channel portion is configured so that the viscous liquid 16 remaining inside the plastic container main body 12 can be discharged or discharged. There are many modes other than the structure shown in FIGS. 4 and 5 and will be described below.

  6A and 6B are diagrams showing a second example of the long channel member, wherein FIG. 6A is a perspective explanatory view showing only the long part with the upper end omitted, and FIG. It is upper surface explanatory drawing which shows the formation state of the flow path in the crushed state. As the long channel portion 26b of the long channel member 18 shown in FIG. 6, the through channel 25b is opened at the center, the lower end is the opening end portion 28, and the notch portion 37 is formed at the lower end side wall portion. A structure using a long cylindrical tube body 30b that is opened is shown. One or a plurality of the notches 37 are formed. Even in this structure, as shown in FIG. 6B, the flow path is formed even when the plastic container body 12 is crushed by pressurization. For example, the plastic container body 12 is crushed. In addition, any one of the opening end portion 28 at the lower end and the one or a plurality of cutout portions 37 can maintain an open state and ensure a discharge flow path for the viscous liquid 16. In addition, if the said notch part 37 is fully opened, it cannot be overemphasized that opening of the lower end opening end part 28 is not essential, and sufficient flow-path ensuring can be performed even if it closes.

  FIG. 7 is a drawing showing a third example of a long channel member. FIG. 7A is a perspective explanatory view showing only the long part with the upper end omitted, and FIG. It is upper surface explanatory drawing which shows the formation state of the flow path in the crushed state. As the long flow path portion 26c of the long flow path member 18 shown in FIG. 7, the through flow path 25c is opened at the center, the lower end is the open end portion 28, and the notch 37 is formed at the lower end side wall portion. A structure using a long prismatic tube body 30c having an opening is shown. Even in this structure, as shown in FIG. 7B, the flow path is formed in a state where the plastic container body 12 is crushed by pressurization, for example, the plastic container body 12 is crushed. However, any one of the opening end portion 28 at the lower end and the one or the plurality of cutout portions 37 can maintain an open state and ensure a discharge flow path for the viscous liquid 16. In addition, if the said notch part 37 is fully opened, it cannot be overemphasized that opening of the lower end opening end part 28 is not essential, and sufficient flow-path ensuring can be performed even if it closes.

  FIG. 8 is a perspective view illustrating the fourth example of the long channel member, omitting the upper end portion and showing only the long portion. As the long channel portion 26d of the long channel member 18 shown in FIG. 8, a long cylindrical tube body 30d having a through channel 25d at the center and an open end 28 at the lower end is used. A structure in which one or more slits 39 are opened on the side wall is shown. According to the long flow path member 18 having this structure, even if the plastic container body 12 is crushed, either the opening end portion 28 at the lower end and one or the plurality of slits 39 maintain the opening state. It is possible to work to ensure a discharge flow path for the viscous liquid 16. It should be noted that if the slit 39 is sufficiently opened, the opening of the lower end opening end portion 28 is not essential, and it is needless to say that a sufficient flow path can be secured even when the slit 39 is closed.

  FIG. 9 is a drawing showing a fifth example of the long channel member. FIG. 9A is a perspective explanatory view showing only the long portion with the upper end omitted, and FIG. FIG. 7C is a top view illustrating the formation state of the flow channel in a crushed state, and (c) is the same drawing as FIG. 5 (b), but only four points on the periphery act on the flow channel formation. It is explanatory drawing of being. As the elongate flow path portion 26e of the elongate flow path member 18 shown in FIG. 9, four plate-like bodies 36 are provided so as to protrude radially from the center portion at equal intervals (in a state intersecting at right angles). And has a shape in which the plate-like body 36 is arranged in a cross shape on the upper surface. According to the elongated flow path member 18 having this structure, even if the plastic container body 12 is crushed, as shown in FIG. The space 38 is not closed and can maintain an open state so as to ensure a discharge flow path for the viscous liquid 16. Although FIG. 9B illustrates the shape in which the upper cross-shaped plate is disposed, it is not always necessary to dispose the upper cross-shaped plate, and as illustrated in FIG. In other words, the flow path can be formed only by the presence of the four flow path forming points 36a in the peripheral portion.

  FIG. 10 is a drawing showing a sixth example of a long channel member. FIG. 10A is a perspective explanatory view showing only the long part with the upper end omitted, and FIG. FIG. 7C is a top view illustrating the formation state of the flow channel in a crushed state, and (c) is the same drawing as FIG. 5 (b), but only four points on the periphery act on the flow channel formation. It is explanatory drawing of being. As the long channel portion 26 f of the long channel member 18 shown in FIG. 10, two plate-like bodies 40 are attached to both ends of the plate-like support pillars 42 so as to face each other. The plate-like body 40 and the plate-like support pillar 42 are arranged in a shape. According to the long channel member 18 having this structure, even if the plastic container main body 12 is crushed, as shown in FIG. 10B, the two plate-like bodies 40 and the plate-like support pillars 42 are used. The two spaces 44 formed by the above are not obstructed and can function to maintain an open state and secure a discharge flow path for the viscous liquid 16. FIG. 10B illustrates the shape in which the plate-like body 40 and the plate-like support column 42 are arranged in an upper surface H shape, but the plate-like body 40 and the plate-like support column 42 are not necessarily arranged in an upper surface H shape. There is no need to do this, and as shown in FIG. 10C, the flow path can be formed even if there are only four flow path forming points 40a in the peripheral portion when viewed from above.

  FIG. 11 is a drawing showing a seventh example of a long channel member, showing a channel formation state in a state where the plastic container body is crushed by pressurization, and only six points on the periphery are channels. It is upper surface explanatory drawing which shows that it acts on formation. 9 and 10, by forming four flow path forming points in the peripheral portion, even if the plastic container main body 12 is crushed, the flow paths are formed by the presence of these four flow path forming points. As described above, FIG. 11 shows a case where six flow path forming points 45 are formed as an example. In addition, the number of points forming the securing of the flow path is not limited to 4 points or 6 points, and as long as it forms a polygon, the flow path is secured by forming more flow path forming points. Of course it can be done.

  FIG. 12 is a perspective view illustrating the eighth example of the long channel member, omitting the upper end portion and showing only the long portion. The elongated channel member 26g of the elongated channel member 18 shown in FIG. 12 is a spiral filament 46 formed by spirally forming a filament, and the center of the spiral filament 46 is formed. A structure is shown in which a hollow 48 is used as a flow path space, an opening end 50 is formed at the lower end, and a predetermined gap 52 is formed between linear bodies. In the case of this structure, for example, even when the plastic container body 12 is crushed by pressure, the central cavity 48 formed by the spiral filament 46 is not closed, and the lower end opening end 50 and It is possible for the gap 52 to maintain an open state and to ensure a discharge flow path for the viscous liquid 16.

  FIG. 13 is a perspective view illustrating the ninth example of the long channel member, omitting the upper end portion and showing only the long portion. As the elongated channel portion 26h of the elongated channel member 18 shown in FIG. 13, a mesh cylinder 53 is formed by forming a mesh body into a cylindrical shape, and the central cavity 54 of the mesh cylinder 53 flows through the central cavity 54. A structure is shown in which an open end 56 is formed at the lower end of the road space and a mesh cylindrical body 53 is formed with a number of mesh voids 58. In the case of this structure, for example, the central cavity 54 formed by the mesh cylindrical body 53 is not closed even when the plastic container body 12 is crushed by pressure, and the lower end opening end 56 and the mesh gap are not closed. It is possible for 58 to maintain an open state and to ensure a discharge flow path for the viscous liquid 16.

  The viscous liquid 16 is a curable composition having a moisture-curable adhesive property that is cured by contact with moisture in the air, or a curable composition having an oxygen-curable adhesive property that is cured by contact with oxygen in the air. When the composition is to be applied, the occurrence of dirt due to the scattering of the viscous liquid as described above is completely prevented, and when the above curable composition is applied, the application is simplified. Therefore, a great work improvement is possible.

  Next, the coating apparatus of the present invention for applying a viscous liquid using the plastic container of the present invention will be described with reference to FIG. FIG. 14 is an explanatory view showing a schematic configuration of the coating apparatus of the present invention. In FIG. 14, reference numeral 60 denotes a coating apparatus of the present invention, which has a pressurized tank 22. The above-described plastic container 10 of the present invention is installed in the pressurized tank 22. The plastic container 10 has a plastic container body 12 and an elongated channel member 18. Reference numeral 62 denotes compressed air supply means for supplying compressed air into the pressurized tank 22 via the air supply pipe 21. Reference numeral 20 denotes a liquid feed pipe means for supplying a viscous liquid. One end of the liquid feed pipe means 20 communicates with the opening 14 of the plastic container body 12, and an application nozzle means 64 is provided at the other end of the liquid feed pipe means 20. It is connected and performs an operation of supplying the viscous liquid filled in the plastic container 10 to the application nozzle means 64. Reference numerals 66 and 68 denote an open-side air supply pipe and a closed-side air supply pipe that connect the compressed air supply means 62 and the application nozzle means 64, respectively, for turning the application nozzle means 64 on and off.

  As described above, the elongate flow path member 18 of the plastic container 10 is detachably attached to the opening 14 of the plastic container main body 12 and has an upper end attaching portion 24 having a liquid discharge port 23 opened at the center. An elongated channel portion 26a integrally attached to the attachment portion 24 so as to extend into the plastic container body 12, and the elongated channel member 18 is the opening portion. 14 is configured to be detachably attached to the device. An upper end mounting portion 24 of the elongated channel member 18 is fitted into the opening 14 of the plastic container body 12, and the liquid feeding means 20 is inserted into the liquid discharge port 23 of the upper end mounting portion 24. It is preferable that the liquid feeding means 20 is inserted into the liquid discharge port 23 in a sealed state by the sealing insertion means 70 having the configuration shown in FIG.

  The sealing insertion means 70 will be described with reference to FIGS. 15 and 16. The sealing insertion means 70 has a fixing member 72. The fixing member 72 has a cylindrical base 74 having an insertion opening 73 at the center, and an annular flange 75 is formed on the lower outer surface of the cylindrical base 74, and the cylindrical base 74 and the bottom surface of the annular flange 75 are formed. The shape is formed so as to have a shape corresponding to the shape of the upper surface of the upper end mounting portion 24 of the long channel member 18, and a receiving step portion 76 is formed on the upper surface of the annular flange 75, and the cylindrical base body 74. The male screw part 78 is formed on the upper outer surface of the. A tapered portion 79 inclined inward is formed at the lower end portion of the cylindrical base body 74. Reference numeral 80 denotes a cap member with a through hole, which has a through hole 84 in contact with the receiving stepped portion 76 at the center of the circular plate 82, and an inner surface side of an annular side wall 86 that is suspended from the peripheral edge of the circular plate 82. Is formed with a female screw portion 88 that can be screwed into a male screw portion 14 b formed on the outer surface of the cylindrical side wall 14 a of the opening 14 of the plastic container body 12. A tightening member 90 includes a cylindrical member 91 having a central hole 92 formed in the center thereof, and a tightening female screw portion 94 is formed in a lower portion of the inner peripheral surface of the cylindrical member 91. As shown in FIG. 16, the upper portion of the center hole 92 of the fastening member 90 is formed so as to gradually decrease in diameter toward the upper portion.

  A mode in which the liquid feeding means 20 is inserted into the liquid discharge port 23 in a sealed state using the above-described sealing insertion means 70 will be described. The fixing member 72 is brought into contact with the upper surface of the upper end mounting portion 24 of the long channel member 18, and the liquid feeding tube is passed through the center hole 92 of the fastening member 90 and the insertion port 73 of the fixing member 72. In a state where the means 20 is inserted into the liquid discharge port 23 of the upper end mounting portion 24 of the elongated channel member 18 and the through hole 84 of the cap member 80 with through hole is inserted into contact with the receiving stepped portion 76. The female screw portion 88 of the cap member 80 with a through hole is screwed into the male screw portion 14b of the cylindrical side wall 14a of the opening portion 14 of the plastic container main body 12 and screwed, and then the upper outer surface of the fixing member 72 is male. By screwing and tightening the tightening female screw portion 94 on the inner surface of the central hole of the tightening member 90 to the screw portion 78, the liquid feeding means 20 is attached to the upper end mounting portion of the long channel member 18. 24 liquid discharge ports 23 sealed It is caused to insertion. As described above, since the diameter of the center hole 92 gradually decreases toward the top, the insertion opening of the fixing member 72 can be obtained by screwing the female screw portion 94 to the male screw portion 78. The upper part of 73 is squeezed, and as a result, the liquid feeding pipe means 20 is clamped and fixed, thereby acting to seal between the liquid feeding pipe means 20 and the fixing member 72.

  The upper end mounting portion 24 of the elongate flow path member 18 shown in FIGS. 15 and 16 is an inner peripheral wall 27 that forms the liquid discharge port 23 and a position separated from the inner peripheral wall 27 by a support wall 29 via a predetermined interval. The inner peripheral wall 27 has an inner diameter that is larger at the upper portion than the lower portion, and the upper end surface of the inner peripheral wall 27 is an inwardly tapered portion 33. It has a structure. On the other hand, the lower end portion of the cylindrical base 74 of the fixing member 72 is a tapered portion 79 inclined inward. Accordingly, when the fixing member 72 is brought into contact with the upper end mounting portion 24 of the elongated channel member 18, as shown in FIG. 15, the upper end taper portion 33 of the inner peripheral wall 27 and the lower end taper portion of the cylindrical base body 74. 79 is in contact with each other to form a sealed state.

  As the material of the fixing member 72, 6-nylon is preferable in terms of toughness, and high-density polyethylene (HDPE) is preferably used in terms of ease of wiping off the attached viscous liquid. Hard polyethylene may be used as the material of the cap member 80 with a through hole, and the material of the fastening member 90 is preferably polyacetal having lubricity.

  In the illustrated example of FIG. 15, the lower end portion of the liquid feeding means 20 is set so as to be flush with the lower end surface of the cylindrical base body 74 of the fixing member 72. Since the lower end portion of the liquid pipe hangs downward from the fixing member 72 and does not become a free end, it is limited that the viscous liquid 16 scatters from the lower end of the liquid feed pipe means 20, so that the occurrence of dirt is greatly increased. There is an advantage of eliminating. The liquid pipe 20 may be suspended to the extent that the lower end portion of the liquid pipe 20 is inserted into the liquid discharge port 23 of the long channel member 18. The smaller it is, the less dirt is generated. Also in the illustrated examples below, the lower end portion of the liquid feeding means 20 is set in the same manner as in FIG. 15, but the description thereof is omitted.

  The combination of the upper surface shape of the upper end mounting portion 24 of the long channel member 18 shown in FIG. 15 and the lower surface shape of the fixing member 72 is conceivable in addition to the example of FIG. explain.

  In the structural example shown in FIG. 17, the taper inclination direction of the upper end taper portion 33 of the inner peripheral wall 27 of the upper end attachment portion 24 of the long channel member 18 and the lower end taper portion 79 of the cylindrical base 74 of the fixing member 72 is illustrated. 15, and the inner diameter of the inner peripheral wall 27 is the same as that of FIG. 15 except that the upper portion and the lower portion have the same diameter. In this case, contrary to the case of FIG. 15, when the fixing member 72 is brought into contact with the upper end mounting portion 24 of the long channel member 18, the upper end taper of the inner peripheral wall 27 is obtained as shown in FIG. The portion 33 and the lower end taper portion 79 of the cylindrical base body 74 are in contact with each other so as to be in a sealed state.

  In the structural example shown in FIG. 18, the installation of the inner peripheral wall 27 of the upper end mounting portion 24 of the long channel member 18 is omitted, the diameter of the liquid discharge port 23 is larger than the diameter of the through channel 25a, and 15 has the same configuration as that of FIG. 15 except that the lower end portion of the cylindrical base 74 of the fixing member 72 extends to the lower side of the support wall 29. In this case, the lower end taper portion 79 of the cylindrical base body 74 is in contact with the inner peripheral edge portion of the support wall 29 so as to be in a sealed state.

  The structural example shown in FIG. 19 is a further modification of the structural example of FIG. 17, and the lower end taper portion 79 of the cylindrical base 74 of the fixing member 72 is omitted and the entire lower surface of the cylindrical base 74 is formed flush. The upper end of the upper end taper portion 33 of the inner peripheral wall 27 of the upper end attaching portion 24 of the long channel member 18 is configured to abut on the lower surface of the cylindrical base body 74.

  The structural example shown in FIGS. 20 and 21A and 21B shows an example in which the auxiliary annular member 95 is used to further improve the sealing action. The auxiliary annular member 95 has a through-hole 96 in the center, and an annular tapered flange 98 is provided on the outer peripheral surface of the lower end portion. The structural example shown in FIGS. 20 and 21A and 21B is basically similar to the structural example shown in FIG. 17, but in the structural example of FIG. The point that the auxiliary annular member 95 is interposed when the screw 90 is screwed is different. In the structural example of FIG. 17, an insertion taper 74 a is formed on the outer surface of the upper end of the cylindrical base 74 of the fixing member 72, and the tip of the cylindrical base 74 is inserted into the center hole 92 of the fastening member 90. 20 and 21, the upper end portion of the cylindrical base body 74 of the fixing member 72 receives the annular taper flange 98 at the lower end portion of the auxiliary annular member 95 described above. Further, a receiving taper portion 74 b is formed on the inner surface of the upper end portion of the cylindrical base body 74. Further, an inner peripheral step 91 a is formed on the inner peripheral portion of the upper end of the cylindrical member 91 of the tightening member 90, and when the auxiliary annular member 95 is inserted into the center hole 92 of the tightening member 90. The inner peripheral step portion 91 a is configured to abut on and fit to the upper side of the annular tapered flange portion 98. The auxiliary annular member 95 may be formed of a plastic material, but is preferably formed of nylon.

  In the structural example shown in FIGS. 21A and 21B, the structure in which the auxiliary annular member 95 is inserted through the center hole 92 of the fastening member 90 is shown. Any member can be used, and a one-touch joint mechanism can be applied, and an example thereof will be described with reference to FIG. In FIG.21 (c), 120 is a fastening member provided with the one-touch coupling mechanism, and has the stepped cylindrical member 122. FIG. A center insertion hole 124 is formed in the stepped cylindrical member 122. A small-diameter cylindrical portion 126 is formed in the lower portion of the stepped cylindrical member 122, and a large-diameter cylindrical step portion 128 is provided in the upper portion. A female screw portion 130 is formed on the inner peripheral surface of the small-diameter cylindrical portion 126. Reference numeral 132 denotes a packing disposed in an annular step space above the stepped cylindrical member 122. A lock crow 134 is attached adjacent to the packing 132. Reference numeral 136 denotes a sleeve that presses the lock crow 134. Reference numeral 138 denotes a presser block that works to hold the sleeve 136. By setting it as such a structure, the liquid feeding means 20 will be inserted in the center insertion hole 124 of the fastening member 120 provided with the one-touch coupling mechanism in the sealing state. Various structures of the one-touch joint are known, and in addition to the structures described above, they are described in Japanese Patent Laid-Open Nos. 1-206196, 4-35669, Utility Model Registration No. 2575755, Utility Model Registration No. 2524012, and the like. One-touch joint structure can also be applied.

  With the above configuration, the operation of the coating apparatus of the present invention will be described. First, when compressed air is supplied into the pressurized tank 22 from the compressed air supply means 62 through the air supply pipe 21, it is installed in the pressurized tank 22 and is viscous as shown in FIG. The plastic container 10 filled with the liquid 16 in a full state is pressurized. Next, as shown in FIG. 2, the plastic container 10 is reduced and deformed by pressurization, and the viscous liquid 16 therein is discharged from the plastic container 10 through the long channel member 18. Next, the discharged viscous liquid 16 is ejected from the application nozzle means 64 via the liquid feeding pipe means 20 and applied to the predetermined portion. In this application operation, when the viscous liquid 16 is completely discharged, the plastic container 10 is crushed by pressurization as shown in FIG. At this time, the viscous liquid 16 filled in the plastic container 10 is not completely discharged by pressure, and only the crushed plastic container body 12 and the long channel member 18 remain. It is in a state. Then, as shown in FIG. 22, the lid 22b is removed from the tank body 22a of the pressurized tank 22, and the used plastic container 10 in a crushed state, that is, the plastic container body 12 and the plastic container body 12, The fixed member 72, the cap member 80 with a through hole, the fastening member 90, and the combined liquid pipe 20 are extracted and separated from the combined material of the long channel member 18 (FIGS. 22 and 23). The combined body of the plastic container main body 12 and the long channel member 18 left in the tank main body 22a is discarded. When the long channel member 18 is taken out from the crushed plastic container 10 and is to be reused, the viscous liquid adhering to the long channel member 18 is scattered to contaminate the work site. However, in the present invention, the crushed plastic container 10, that is, the plastic container main body 12 and the elongate flow path member 18 are formed so as to be disposable. There is an advantage that such contamination does not occur.

  In the apparatus in which the long channel member of the present invention is not installed in the plastic container 106, the liquid feeding pipe means 110 is extended into the plastic container 106 and thrust into the viscous liquid 112 for use. In this case, since the flow path is easily closed when the tip of the liquid feeding pipe means 110 is blocked, an accident may occur such that the entire viscous liquid 112 in the plastic container 106 is not discharged. Even if the entire viscous liquid 112 is discharged, as shown in FIG. 24, when the lid 102b is removed from the tank body 102a of the pressurized tank 102 and the liquid feeding pipe means 110 is pulled out from the plastic container 106, the liquid feeding is performed. In addition to the problem that the viscous liquid 112 adhering to the pipe means 110 scatters, in order to prevent the scattering, the viscous liquid 112 needs to be wiped off from the liquid feeding pipe means 110 with a waste cloth. . Further, at that time, it is only necessary to wipe off cleanly. However, if the number of times is increased, the residue of the viscous liquid 112 (for example, a cured adhesive) adheres to the liquid feeding means, and the liquid feeding means 110 is used again. At this time, the residue becomes liable to be mixed into the viscous liquid 112, which may cause clogging of each member such as the application nozzle means, resulting in inconvenience that the viscous liquid 112 (for example, adhesive) cannot be applied. End up. In particular, moisture-curing adhesives tend to cause residue of the adhesive and clogging of each member such as the application nozzle means becomes a problem.

  Furthermore, in a pressurized tank used when applying a viscous liquid, for example, a moisture curable adhesive, a pressure of about 0.3 to 0.6 MPa is generally used. Therefore, in order to withstand the pressure and maintain high sealing performance, the lid of the pressurized tank is formed to be thick and heavy (for example, about 6 to 10 kg). The switching operation is usually carried out by three workers (one of whom is changing the plastic container including the insertion and removal of the long liquid feeding means while the other two are lifting the lid). It is what. When replacing the plastic container containing the viscous liquid after the application work is completed, as shown in FIG. 24, remove the lid, remove the liquid feeding tube means from the plastic container, and discard the old plastic container. Next, it is necessary to carry out an operation such as storing a new plastic container in the pressurized tank and inserting a long liquid feeding pipe means into the plastic container, and the viscous liquid from the tip of the liquid feeding means, For example, the occurrence of contamination due to the scattering of the adhesive frequently occurs. In addition, when using a moisture-curing type adhesive having a fast curing speed (curing in 3 to 10 minutes) as a viscous liquid, a particularly quick work is required, and the work is difficult. Become.

  Such various problems in the case of using only the conventional liquid feeding pipe means are all solved by using the plastic container 10 provided with the long channel member 18 of the present invention. For example, the above-described plastic container switching operation was performed by three persons as described above, but by applying the plastic container of the present invention, two persons (one person remains while lifting the lid). It is possible to carry out by one person changing the plastic container including inserting and removing the long liquid feeding pipe means. The plastic container, the long channel member and the coating apparatus of the present invention effectively solve the above-mentioned problems that have been regarded as a major problem in the industry, and have a great merit. As one means for solving the problem that the viscous liquid 16 scatters from the tip of the liquid feeding pipe means 20 and causes dirt, as described in the explanation of the illustrated example of FIG. It is effective to employ a configuration in which the front end portion does not protrude downward from the fixing member 72.
