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).

  Patent Documents 1 and 2 described above both relate to an apparatus for applying a liquid that dislikes contact with air. However, liquid feeding means such as a hose and a tube, a storage container, a pressurized container (pressurized tank), etc. Since the strict mechanism is not necessarily adopted for the sealing structure of the connecting part, it is inevitable that various troubles occur due to the liquid curing due to the intrusion of air from those connecting parts. .

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings, but these are exemplarily shown, and it goes without saying that various modifications are possible without departing from the technical idea of the present invention.

  FIG. 1 is an explanatory view showing a schematic configuration of a coating apparatus of the present invention. In FIG. 1, reference numeral 60 denotes a coating apparatus of the present invention, which has a pressurized tank 22. A plastic container 10 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 wide opening 14 of the plastic container body 12, and an application means 64 is provided at the other end of the liquid feed pipe means 20. It is connected and performs the operation of supplying the viscous liquid filled in the plastic container 10 to the coating 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 means 64, and turn on and off the application means 64, respectively. Examples of the application unit 64 include a nozzle unit, a spray unit, and a roll coater.

  An elongate flow path member 18 of the plastic container 10 is detachably attached to the wide opening 14 of the plastic container main body 12 and has an upper end attachment portion 24 having a liquid discharge port 23 opened in the center, and the plastic container. A long passage portion 26a integrally attached to the upper end attachment portion 24 so as to extend inside the main body 12, and the long passage member 18 is formed in the wide opening 14. It is configured to be detachably mounted.

  FIG. 2 is a cross-sectional explanatory view showing an embodiment in which a plastic container is installed inside a pressurized tank, and shows a state in which the plastic container body is filled with a viscous liquid. In FIG. 2, reference numeral 10 denotes a plastic container having 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. A wide-mouth opening 14 is opened at the top 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 squeezed viscous liquid 16 is pressed and discharged from the wide-mouth opening 14 via the liquid feed 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. Examples of the viscous liquid 16 include a curable composition having adhesiveness. 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 coating apparatus of the present invention, when applied to a viscous liquid having a viscosity and tack-free time in the above range, a great effect is achieved that it is less likely to become dirty than conventional products.

  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.

  In FIG. 2, reference numeral 18 denotes an elongate flow path member, which is attached to the wide mouth opening 14 so as to extend into the plastic container main body 12, and the viscosity when the viscous liquid 16 is discharged under pressure. The liquid 16 is configured to have a function of ensuring the flow path of the liquid 16. The long channel member 18 only needs to act so as to form a viscous liquid channel, and various forms can be considered as will be described later. In the illustrated example of FIG. A long passage portion 26a composed of a long cylindrical tube body 30a integrally attached to the upper end 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, a plurality of) channel holes 32 are opened in the side wall of the long 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 it is flexible plastic material, for example, polyethylene, polypropylene, nylon, fluoro rubber, silicone cone rubber, EPDM, because it is easy to fit. , SBS, SIS, SEBS, etc. are good, injection molding is easy and inexpensive, and 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. Further, as the material of the long channel member 18, hard polyethylene can be used, but this hard polyethylene has an advantage that flexibility can be provided by adjusting its thickness. For example, if the long channel portion 26a has a thickness of about 5 mm and the upper end mounting portion 24 has a thickness of about 0.7 mm, it is possible to provide appropriate flexibility.

  In FIG. 2, reference numeral 22 denotes a pressurized tank, which is configured such that pressurized air is introduced into the inside through a compressed air supply means (not shown) through an air supply pipe 21. When the plastic container 10 is used, it is used in a state where it is installed in the pressurized tank 22, and as shown in FIG. 3, pressure (for example, pressurizing conditions 0.3 to 1 is applied from the outside of the plastic container 10). 0.0MPa), the plastic container body 12 is pressurized and deformed, and the viscous liquid 16 inside is discharged from the wide-mouth opening 14 through the liquid feeding means 20, and finally, FIG. As shown, the plastic container main 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. 4, in other words, the plastic container main body 12 and the long 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.

  FIG. 12 is an explanatory view showing an example of a long channel member used in a plastic container used in the coating apparatus of the present invention, where (a) is a top view and (b) is a cross-sectional view. FIG. 13 is a view showing a long channel member similar to FIG. 12, where (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. . As shown in FIGS. 12 and 13, the long channel member 18 is attached to the wide opening 14 of the plastic container body 12 and has an upper end attachment 24 having a liquid discharge opening 23 in the center. And an elongate flow passage portion 26a integrally attached to the upper end attachment portion 24 so as to extend into the plastic container main body 12 and having a through flow passage 25a opened at the center thereof. Yes.

  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 an upper end 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. By fitting the outer peripheral step 35 to the outer peripheral edge of the wide-mouth opening 14 of the plastic container body 12, the elongated channel member 18 can be detachably attached to the wide-mouth opening 14.

  Since the wide opening 14 of the plastic container body 12 is formed in a wide opening, the long flow path member 18 can be attached to the wide opening 14 in a detachable manner. When the viscous liquid 16 is injected into the plastic container body 12 without the member 18 being fitted, the viscous liquid 16 can be injected from the wide opening 14 with a margin. The procedure for fitting the road member 18 to the wide 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 wide opening 14 in advance, the viscous liquid 16 passes through the liquid discharge port 23 opened narrowly in the elongate flow path member 18. The viscous 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 shown in FIGS. 2 to 7, one or a plurality of long channel portions 26 a of the long channel member 18 are provided on the side wall of the long cylindrical tube body 30 a whose lower end is the lower end opening end portion 28 (see FIG. 2). In the illustrated example, a structure in which a plurality of flow path holes 32 are opened is shown. According to the elongated flow path member 18 having this structure, even if the plastic container body 12 is crushed, either the lower end opening end 28 and one or the plurality of flow path holes 32 maintain the open state. Thus, it is possible to work so as to secure a discharge flow path for the viscous liquid 16. In the above configuration, since the flow passage hole 32 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 wide opening 14 and finally. In particular, it 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. In addition to the structure shown in FIG. 12 and FIG. 13, many modes are conceivable. In short, when the viscous liquid 16 is extruded from the plastic container main body 12, it acts to ensure a discharge flow path for the viscous liquid 16. Needless to say, the structure is not limited to the structures shown in FIGS. 12 and 13.

  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.

  2 to 9, reference numeral 70 denotes a sealing communication means, which has a lower surface shape corresponding to the upper surface shape of the upper end mounting portion of the elongated channel member 18, and a receiving step portion 76 is formed on the lower upper surface. In addition, a long cylindrical base 74 having an insertion opening at the center is provided. A lower end taper portion 79 inclined inward is formed in the lower end opening of the long cylindrical base 74. Reference numeral 80 denotes a cap member, which has an annular side wall 86 that has a through hole 84 that is in contact with the receiving stepped portion 76 of the long cylindrical base body 74 at the center of the circular plate 82 and is suspended from the peripheral edge of the circular plate 82. A female screw portion 88 that can be screwed into a male screw portion 14b formed on the inner surface of the cylindrical side wall 14a of the wide opening 14 of the plastic container body 12 is formed on the inner surface side of the plastic container body 12. The upper end opening 74a of the long cylindrical base 74 has a size corresponding to the tip opening 20a of the liquid feeding means 20, and the upper end opening 74a and the tip opening 20a are as will be described later. It can be hermetically sealed in communication. Although there is no particular limitation on the shape of the cap member 80, as shown in FIG. 16, if a plurality of (eight in the illustrated example) concave portions 86a are formed on the outer peripheral surface of the annular side wall 86, the cap is formed.

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. With this configuration, the liquid feeding unit 20 is mounted in a sealed state in the upper insertion port 246 of the upper cylindrical holding member 240 to which the tightening member 120 having the one-touch joint mechanism is screwed. In the above description of FIG. 17 and FIG. 18, the case where the liquid feeding means 20 is held by the upper cylindrical holding member 240 to which the fastening member 120 having the one-touch joint mechanism is screwed has been described. The same is achieved by a configuration (not shown) in which the provided clamping member 120 is screwed to the lower cylindrical holding member 206 and a configuration (not shown) in which the clamping member 120 having the one-touch joint mechanism is screwed to the cylindrical holding member 282. Of course, the long cylindrical base 74 can be held, and illustration and description of a specific configuration in that case will be omitted to avoid redundancy. 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.

  In addition to the structural example using the auxiliary cylindrical bodies 222, 256, and 294 shown in FIGS. 8 and 9, and the tightening member 120 provided with the one-touch joint mechanism shown in FIGS. Can be adopted. For example, as shown in FIGS. 19 (a) and 19 (b), the diameter becomes smaller in the downward direction at the upper end portion of the inner peripheral surface of the upper insertion port 246 of the upper cylindrical holding member 240 without using an auxiliary cylindrical body. As shown in FIG. 19 (b), a configuration in which one or more (three in the illustrated example) annular tapered portions 246a having a wedge-shaped cross section can be employed. In the description of FIG. 19 described above, the case where the liquid feeding pipe means 20 is held has been described. However, by applying a configuration in which an annular tapered portion is formed in the lower cylindrical holding member 206 and the cylindrical holding member 282, the length is similarly increased. Of course, the cylindrical substrate 74 can be held, and illustration and description of a specific configuration in that case will be omitted to avoid redundancy.

  In the coating apparatus shown in FIGS. 2 to 9, the upper end opening portion 74 a of the long cylindrical base body 74 and the front end opening of the liquid feed pipe means 20 are connected via a female screw portion 202 screwed to the cylindrical base body 204. The structure in which the portion 20a is hermetically bonded has been described. As shown in FIGS. 10 and 11, the long cylindrical base body 74 is provided via the lid female screw portion 22d screwed to the lid body 22b of the pressurized tank 22. It is also possible to adopt a configuration in which the upper end opening 74a of the liquid and the tip opening 20a of the liquid feeding pipe means 20 are hermetically joined. In this configuration, the installation of the cylindrical base body 204 and the attachment means 280 can be omitted. Therefore, there is an advantage that the cost can be reduced accordingly. The configuration will be described below.

  In the configuration of the coating apparatus shown in FIGS. 10 and 11, the installation means 280 for inserting and attaching the long cylindrical base body 74 shown in FIGS. 2 to 9 to the lid female screw portion 22 d and the cylindrical base body 204 are installed. The screwing holding portion 22D provided with the lid female screw portion 22d screwed to the lid body 22b of the pressurizing tank 22 has an action corresponding to the female screw portion 202 of the cylindrical base body 204. It replaces and it can utilize the same member, without changing about another member. 10 and 11, the description of FIGS. 2 to 9 using the cylindrical base body 204 is performed by replacing the female screw portion 22d of the lid body in place of the female screw portion 202 of the cylindrical base body 204 as it is. Since it can be used, a re-explanation is omitted to avoid redundancy.

  In FIGS. 8 and 9, the example in which the sealing joint means 200 has the cylindrical base body 204, the lower cylindrical holding member 206, and the upper cylindrical holding member 240 as separate bodies has been described, but these are integrally formed. It is also possible to perform the same operation, and a structural example in that case will be described with reference to FIGS. 23 and 24, reference numeral 350 denotes a cylindrical holding member, which includes an insertion port 352 that is formed so as to penetrate in the vertical direction. A central base body 354 is provided at the center of the cylindrical holding member 350. An upper diameter small cylindrical portion 356 is provided on the upper portion of the central base body 354, and a lower diameter small cylindrical portion 358 is provided on the lower portion.

An upper annular female taper portion 364 is formed at the upper end portion of the upper small diameter cylindrical portion 356, and a lower annular female taper portion 366 is formed at the lower end portion of the lower diameter small cylindrical portion 358.

  23 and 24, the upper end portion of the long cylindrical base body 74 is inserted into the through hole 232 of the lower annular fastener 230 and the lower portion of the insertion port 352 of the cylindrical holding member 350, and the liquid feed pipe unit 20 The distal end portion is inserted into the through hole 266 of the upper annular fastener 264 and the upper portion of the insertion port 352 of the cylindrical holding member 350, and then the female screw portion 234 of the lower annular fastener 230 is screwed into the lower male screw portion 362. And an upper threaded portion 268 of the upper annular fastener 264 is screwed into the upper male threaded portion 360, whereby an upper end opening portion 74a of the long cylindrical base 74 and a distal end opening portion 20a of the liquid feeding means 20 are Can be sealed and joined in a communicating state so that the upper end opening 74a of the long cylindrical base 74 and the tip opening 20a of the liquid feeding means 20 can be sealed and joined. In FIGS. 23 and 24, the lower auxiliary cylinder 222 and the upper auxiliary cylinder 256 are used to enhance the fastening effect of the lower annular fastener 230 and the upper annular fastener 264, as described above. Needless to say, a sufficient tightening effect can be obtained even if its use is omitted.

  10 and 11, the structure example in which the lower cylindrical holding member 206 and the upper cylindrical holding member 240 are separately provided as the sealing joint means 200 and screwed into the screw holding portion 22D has been described. The member 206 and the upper cylindrical holding member 240 can be integrally formed to perform the same operation, and a structural example in that case will be described with reference to FIGS. 25 and 26. In FIGS. 25 and 26, reference numeral 400 denotes a long cylindrical holding member having an insertion port 402 penetrating vertically. A central base body 404 is provided at the center of the long cylindrical holding member 400. An upper diameter large cylindrical portion 406 is provided on the upper portion of the central base body 404, and an upper diameter smaller cylindrical portion 408 is connected to the upper portion of the upper diameter large cylindrical portion 406. A lower-diameter cylindrical portion 410 is provided at the lower portion of the central base body 404. An upper diameter large male screw portion 412 is screwed on the outer surface of the upper diameter large cylindrical portion 406, and an upper diameter small male screw portion 414 is screwed on the outer surface of the upper diameter small cylinder portion 408, and the lower diameter small cylinder A lower-diameter small male screw portion 416 is screwed on the outer surface of the portion 410. An upper annular female taper portion 418 is formed at the upper end portion of the upper small diameter cylindrical portion 408, and a lower annular female taper portion 420 is formed at the lower end portion of the lower diameter small cylindrical portion 410.

  25 and 26, the upper diameter large male screw portion 412 of the long cylindrical holding portion 400 is screwed into the screw holding portion 22D, and the upper end portion of the long cylindrical base body 74 is penetrated by the lower annular fastener 230. The hole 232 and the lower portion of the insertion port 402 of the long cylindrical holding member 400 are inserted, and the tip portion of the liquid feeding means 20 is inserted through the through hole 266 of the upper annular fastener 264 and the long cylindrical holding member 400. Insert the female screw portion 234 of the lower annular fastener 230 into the lower diameter small male screw portion 416 and insert the upper annular fastener 264 into the upper diameter small male screw portion 414. By screwing a female screw portion 268, the upper end opening portion 74a of the long cylindrical base body 74 and the front end opening portion 20a of the liquid feed pipe means 20 are hermetically sealed and joined to each other. A tip opening 20a of the opening 74a and the liquid flue means 20 can be allowed to hermetically bonded. In FIGS. 25 and 26, the lower auxiliary cylinder 222 and the upper auxiliary cylinder 256 are used to enhance the fastening effect of the lower annular fastener 230 and the upper annular fastener 264, as described above. Needless to say, a sufficient tightening effect can be obtained even if its use is omitted.

  With the above configuration, the operation of the coating apparatus of the present invention will be described with reference to FIGS. 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. 3, 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. Subsequently, the discharged viscous liquid 16 is ejected from the application means 64 through the liquid feed pipe means 20 and applied to the predetermined portion. In this coating operation, in the state where all the viscous liquid 16 is discharged and used, 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. 14, the lid 22b is removed from the tank body 22a of the pressurized tank 22, and then the used plastic container 10 in a crushed state, that is, the plastic container body 12 and the long flow path. The combined body of the sealing communication means 70, the cap member 80, and the liquid feeding pipe means 20 is extracted from the combined body of the member 18 and separated, and the plastic container body 12 and the long channel member 18 remaining in the tank body 22a are separated. The union 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. Note that the operation of the coating apparatus shown in FIGS. 10 to 11 is substantially the same as that described above, and thus the description thereof is omitted.

  In an apparatus in which the long channel member as shown in FIG. 15 is not installed in the plastic container 106, the liquid feeding pipe means 110 is extended into the plastic container 106 and used by being thrust into the viscous liquid 112. Become. 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. 15, when the lid 102 b is removed from the tank body 102 a 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 1.0 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. 14, the lid is removed, the liquid feeding means is removed from the plastic container, and the old plastic container is discarded. 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.

  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. For example, the above-described plastic container switching operation was performed by three persons as described above, but by applying the plastic container in the coating apparatus of the present invention, two persons (while one person is lifting the lid) The remaining one person can replace the plastic container including the insertion and removal of the long liquid feeding pipe means).
