Description

Plastic container, long flow member and coating apparatus

The present invention deforms a viscous liquid, in particular a curable composition having a moisture-curable adhesive or a curable composition having an oxygen-curable adhesive in a flexible bag or container and applying a pressure from the outside to deform the bag or container. Plastic containers, long flow path members, coating devices, caps for closures, plastic containers in sealed state and packaged state, which are effectively used to reduce and discharge the internal viscous liquid to the outside. Relates to a plastic container.

Conventionally, in the coating apparatus which apply | coats a moisture hardening type adhesive agent or an oxygen hardening type adhesive agent, since an adhesive agent hardens when it contacts air, when an adhesive agent scatters, it will harden as it is at the scattering point, and will cause a dirt. It is necessary to apply the adhesive in a state where it does not come into contact with the air.

The general discharge form of the viscous liquid in this type of conventional coating device will be described with reference to Figs. 25 to 27, reference numeral 100 denotes an original coating device, and compressed air supply means (not shown) for supplying compressed air through the air supply pipe 104 in the pressurized tank 102 and the pressurized tank 102. ), The liquid container 106 installed in the pressurized tank 102, the liquid conveying pipe means 110 having one end communicating with the opening 108 of the plastic container 106, and the liquid conveying pipe means 110. It has a coating nozzle means (not shown) provided in the other end. Reference numeral 112 is a viscous liquid and 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 in a filled state, and FIG. 26 shows that the viscous liquid 112 is deformed and reduced as the plastic container 106 is pressed outward. The intermediate state discharged to the outside is shown, and FIG. 27 shows the final state in which the plastic container 106 is further pressed so that the viscous liquid 112 is not discharged to the outside due to the central portions contacting each other. In addition, in some cases, the liquid conveying pipe means 110 extends to the inside of the plastic container 106 through the opening 108 of the plastic container 106, but in this case, the liquid conveying pipe means 110 is used. Since the liquid is repeatedly used, the viscous liquid adheres to the tip of the liquid conveying pipe means 110 when the liquid feeding process is completed. Therefore, the adhered viscous liquid scatters around the coating device, causing the dirt. It becomes.

Proposals for applying liquids that avoid such contact with air have also been around for a long time. For example, an apparatus in which a viscous liquid or the like is stored in a flexible bag or container and the pressure is applied from the outside to deform and shrink the bag or container so that the viscous liquid inside is discharged and applied to the outside is referred to as an "adhesive agent." An adhesive applying device comprising: a deformable sealed container filled with a pressure vessel, a pressurized tank containing a sealed container, a hose connecting the discharge portion disposed outside the pressurized tank and a sealed container, and a pressurizing device to the pressurized tank. Adhesive application device which filled water-based adhesive, connected the tip of hose connected to airtight container to atomizer, and provided flange-shaped reinforcement part which regulates deformation at the time of shrinkage on the outer wall surface of hose installation part of sealed container. " Claim 1) of patent document 1 is known. Regarding the adhesive coating device of Patent Document 1, in the conventional coating device of this kind, as described in paragraph 0004 of Patent Document 1, it is smoothly discharged at the time of the discharge operation of the adhesive, but near the installation portion of the hose of the bag. By providing a flange-shaped reinforcement part for restricting deformation during shrinkage on the wall surface of the outer side of the hose installation part of the sealed container, the accident that the membrane body becomes impossible to discharge by blocking the connection part with the hose. It is to be resolved. The apparatus of Patent Document 1 is effective in reliably eliminating the inability to discharge in the vicinity of the hose mounting portion, but in other envelopes or portions of the container, for example, in the center portion of the envelope or container as shown in FIG. It does not fully function against a non-discharge accident.

Moreover, as a coating device, it is connected to the fluid introduction means and the pump unit which are connected to the liquid container of any one of Claims 1-7 and the liquid discharge port of the inner container which comprises the said container, and introduce a pressure fluid therein. And a means for spraying the liquid to be discharged by being pressurized by the pump unit to the to-be-coated object. ”(Claim 8 of Patent Document 2 below) is also known. In this coating device, as a container for liquid, "the container for discharging the liquid without the contact with air and discharging the liquid without invading air as much as possible, is free of volume. Flexible bag shape that can be changed into material, the inner container is provided with a liquid outlet connected to the pump unit for discharging the liquid, the volume is unchanged and can be sealed with the inner container accommodated, the inner container is accommodated And an outer container into which the pressure fluid is introduced in a sealed state so that the liquid contained in the inner container is discharged to compress the air region formed inside the inner container into the pressure fluid introduced into the outer container. The liquid is drained from the inner container so as not to intrude air as much as possible into the inner container. And a container for liquid, characterized in that it is allowed to exit. ”(Claim 1 of Patent Document 2) is disclosed. In addition, in patent document 2, about the said inner container, "the inside of the inner container 1, the suction hose 6 connected to the paint outlet 5 is extended and provided, and the length of this suction hose 6 is carried out. Is slightly longer than the height of the inner container 1 at the time of expanding into a cube shape. For this reason, the tip of the suction hose 6 is always in contact with the bottom face of the inner container 1, and can accommodate all of the water-based paint P contained in the inner container 1. ”(Patent Document 2, Short Circuit) 0025) to teach the use of the suction hose (6). As for the apparatus of Patent Document 2, the suction hose 6 is used as a viscous liquid because the viscous liquid adheres to the tip of the suction hose 6 when the liquid transfer process is completed for repeated use. It is the same as in the case of Patent Document 1 that the (water-based paint in Patent Document 2) scatters around the coating device and causes dirt, and the suction port of the suction hose 6 is the tip of the suction hose 6. Since the suction port is blocked due to contact with the wall of the inner container 1 or the like, there is a disadvantage in that an accident that the suction of the viscous liquid is not performed occurs.

It is very suitable that the elongate flow path part is a tubular body having one or more flow path holes perforated.

The coating device of the present invention includes a pressurized tank and compressed air supply means for supplying compressed air into the pressurized tank, a liquid conveying tube means in which one end communicates with the plastic container of the present invention provided in the pressurized tank and an opening of the plastic container; And a coating nozzle means connected to the other end of the liquid conveying pipe means, and when compressed air is supplied into the pressurized tank, the plastic container installed in the pressurized tank is pressurized to compress the viscous liquid therein to form the elongated flow path member. Discharged from the plastic container by intervening, and then ejected from the application nozzle means via the liquid conveying pipe means to apply the viscous liquid to a predetermined portion, and the plastic container body is compressed by pressurization and filled therein After all the viscous liquid has been pressurized and discharged, the compressed plastic Characterized in that one to be disposed of with the tick-box body and said elongate the flow path member.

In the coating device of the present invention, the elongated flow path member is detachably attached to the opening of the plastic container body, and the upper mounting portion having the liquid ejection opening in the central portion thereof and the installation so as to extend inside the plastic container body. Having a long flow path portion integrally installed at the portion, the long flow path member being configured to be detachably mounted to the opening, and attaching an upper mounting portion of the long flow path member to the opening of the plastic container body; It is very suitable to insert the liquid delivery pipe means into the liquid discharge port of the upper installation portion, and to press-fit the liquid delivery pipe means to the liquid discharge port in a sealed state due to the sealing insertion means.

The sealing inserting means has a lower lower surface shape corresponding to the upper surface shape of the upper mounting portion of the elongate flow path member, while forming a receiving end portion on the lower surface and a male screw portion on the upper outer surface, and at the same time inserting the insertion hole in the center portion. A male screw portion formed on the outer surface of the cylindrical side wall of the opening of the plastic container body on the inner surface side of the annular side wall vertically formed at the periphery of the circular plate, while forming a through-hole contacting the receiving end portion in the central portion of the circular plate and the fixing member having the opening; A cap member with a through-hole formed therein with a female screw portion capable of screwing thereon, and a fixing member having a central hole formed in the central portion thereof and a female screw portion formed on an inner surface of the central hole, wherein the fixing member is formed at an upper end portion of the elongated flow path member. The center hole of the fixing member and the The plastic pipe is inserted through the insertion hole of the positive member into the liquid discharge port of the upper installation portion of the elongate flow path member, and the through hole of the cap member with the through hole is in contact with the receiving end. Screw the screw by connecting the female threaded portion of the plug member through which the through hole is drilled to the male threaded portion of the cylindrical side wall of the opening of the container body, and then to the male threaded portion of the upper outer surface of the fixed member of the inner surface of the center hole of the fixed member. Preferably, the female threaded portion is screwed together to be screwed so that the liquid conveying pipe means can be inserted into the liquid discharge port of the upper mounting portion of the elongate flow path member in a sealed state.

The 1st form of the cap for plugging of this invention is a cap for plug used in order to seal the opening part of the plastic container main body of the plastic container of this invention, The said plastic is in the inner surface side of the annular side wall installed perpendicularly to the periphery of a circular plate. And a cap body having a female screw portion that can be screwed to a male screw portion formed on an outer surface of a cylindrical side wall of an opening of the container body, and a cap member vertically installed at a central portion of the lower surface of the circular plate to be coupled to the liquid discharge port of the elongated flow path member. do.

The second shape of the cap for a closure of the present invention is a more preferably structured, flexible cylindrical cylindrically installed vertically at the lower circumferential edge of the circumferential vertical bottom and vertically arranged at the center of the lower surface of the circular plate as the closure member. It is set as the structure which has a coupling part. The flexible cylindrical coupling has an extremely high flexibility since the lower end is a free end. In the case of the structure in which only the circumferential vertical lower part is provided as a stopper when the stopper member coupled to the liquid discharge port of the long channel member is removed from the liquid discharge port, the upper part of the circumferential vertical lower part is fixed while the lower part is hard. Because of its extremely low mobility, it is difficult for the columnar vertical lower part to be easily drawn off from the liquid discharge port, and to be pulled out together with the elongated flow path member. On the other hand, if there is a structure in which a cylindrical coupling portion having flexibility is provided at the lower end of the circumferential vertical lower portion as a closure member, the cylindrical coupling when the plug member in a state coupled to the liquid discharge port of the elongate flow path member is removed from the liquid discharge port of the elongate flow path member. There is an advantage that it can be easily removed from the liquid discharge port even if there is some imbalance during molding without hard coupling to the liquid discharge port by the negative softening action.

The plastic container of the sealed state of this invention fills the said viscous liquid inside the said plastic container main body, and closes the opening of the plastic container main body with a cap, The moisture | condensation or oxygen impermeable material of the plastic container of this invention is carried out. It is characterized in that it is housed in a moisture or oxygen impermeable bag formed by the seal and becomes a sealed state. As the cap, the cap for the closure of the present invention described above is suitably used. It is very suitable that the liquid discharge port of the elongate flow path member is closed by the cap member using the cap for cap of the present invention described above as the cap. As said moisture or oxygen impermeable material, the multilayer sheet-like material which contains at least one layer of aluminum thin layers is used suitably.

The plastic container in the packaged state of the present invention is characterized in that the plastic container in the sealed state of the present invention is packaged by corrugated cardboard.

According to the plastic container of this invention, the plastic container main body which has the flexibility which fills an opening and filled the viscous liquid, especially the curable composition which has the adhesiveness of moisture-hardening type | mold, or the curable composition which has the adhesiveness of oxygen-curable type | mold is pressurized by pressurization. Wherein the viscous liquid is pressurized to eject the viscous liquid from the opening, and the elongated flow path member is provided in the opening so as to extend inside the plastic container body, so that the viscous liquid is pressurized and discharged. When the flow path of the viscous liquid is formed and the plastic container body is compressed, the flow path of the viscous liquid is not blocked, and the viscous liquid is compressed by pressurization and all the viscous liquid contained therein is pressurized and discharged. After that, the compressed plastic container body and the cabinet When the chuck-like flow path members are all discarded, a viscous liquid adhered to the tube member when the tube member such as a suction hose is repeatedly used, in particular, a curable composition having an adhesive of a moisture curing type or a curable composition having an oxygen curing type of adhesive The effect which can eliminate what scatters and causes the surrounding dirt can be achieved.

The elongate flow path member of the present invention is used by being mounted to the opening of the plastic container body with respect to the plastic container of the present invention, or by being used in the opening of a plastic container of the type which presses and ejects the liquid contents due to the existing pressure. The effect of being able to press-eject efficiently the liquid contents of a plastic container without leaving a residual liquid is achieved.

According to the coating apparatus of this invention, since the plastic container of this invention is arrange | positioned, since the pressure discharge of the liquid content can be carried out efficiently without leaving a residual liquid, application efficiency is improved and the viscous liquid which is an internal content especially, especially The curable composition having the moisture-curable adhesiveness or the curable composition having the oxygen-curable adhesiveness can achieve the effect of eliminating scattering and causing the surrounding dirt.

When preserving a plastic container filled with a viscous liquid, or when transporting a plastic container with a viscous liquid, it is common to close the opening of the plastic container with a cap. In this case, if a cap having a general structure is used for closing the opening of the plastic container of the structure of the present invention and the liquid discharge port of the long channel member, when the cap is removed, the viscous liquid is formed on the inner surface portion of the circular plate in contact with the liquid discharge port. And the upper end of the inner circumferential surface of the long channel member is attached. In this state, the liquid conveying pipe means communicates with the elongate flow path member, and the fixing member, the cap member with the through hole, and the fixing member are attached to perform the pressure discharge operation of the viscous liquid. When the pipe conveying means, the fixing member, the cap with a through hole, and the fixing member are removed, a viscous liquid adheres to the outer peripheral surface of the lower tapered portion of the cylindrical body of the fixing member and becomes dirty. When the adhered viscous liquid hardens with time, if the lower taper portion and the upper taper portion of the elongated flow path member become difficult or deep, the bond becomes incapable of joining. Disadvantage to be caused occurs.

In order to solve the difficulty caused by the use of the cap of the general structure as described above, the inventors are screwed to the male thread formed on the outer surface of the cylindrical side wall of the opening of the plastic container body on the inner surface side of the annular side wall vertically installed from the periphery of the circular plate. It is proposed a cap for a first shape having a cap body having a female thread portion possible, and a cap member vertically installed at a central portion of the lower surface of the circular plate so as to be coupled to the liquid discharge port of the long channel member. When the cap for the plug of the first aspect of the present invention is used for the closing of the opening of the plastic container of the structure of the present invention and the liquid discharge port of the long channel member, the plug member is driven into the upper portion of the through channel of the long channel member. It is in the state of being put in, and viscous liquid does not penetrate into the upper end part of this through flow path, and viscous liquid does not adhere to the upper end part of a through flow path. Therefore, when the cap for cap is removed, a viscous liquid does not exist in the upper end part of a through flow path, and neither a dirt generate | occur | produces and it is a clean state.

In this state, the liquid conveying pipe means communicates with the elongated flow path member, and the fixing member, the cap member with the through hole, and the fixing member are mounted to perform the pressure discharge operation of the viscous liquid, and when the pressure discharge operation is completed, the liquid delivery tube means In a state where the fixing member, the cap member with a through hole, and the fixing member are removed, a viscous liquid does not exist on the outer circumferential surface of the lower tapered portion of the cylindrical body of the fixing member and is in a clean state. Therefore, even when used next time, there is an advantage that it can be used without any problem as in the first use.

In addition, the present inventors have a structure of a cap for caps, which has a cylindrical cylindrical lower portion vertically provided at the center of the lower surface of the circular plate as the cap member and a flexible cylindrical engaging portion provided perpendicularly to the lower circumferential edge of the columnar vertical lower portion. The structure of the cap for plugs of the form 2 is proposed. When the second shape cap for capping of the present invention is used for the closing of the opening of the plastic container of the structure of the present invention and the liquid discharge port of the long channel member, the cap member is driven into the upper portion of the through channel of the long channel member. It becomes a state, and viscous liquid does not penetrate into the upper end part of this through flow path, and viscous liquid does not adhere to the upper end part of a through flow path. Therefore, when the cap for caps is removed, a viscous liquid does not exist in the upper end portion of the through flow path, and no dirt is generated, and the state is in a clean state.

From this state, the liquid conveying pipe means communicates with the elongate flow path member, and the fixing member, the cap member with the through hole, and the fixing member are attached to perform the pressure discharge operation of the viscous liquid. In a state where the pipe conveying means, the fixing member, the cap member with the through hole, and the fixing member are removed, a viscous liquid does not exist on the outer peripheral surface of the lower tapered portion of the cylindrical body of the fixing member. Therefore, there is an advantage that can be used without any problem as the first time even when used next time.

In addition, as described above, in the case where the circumferential vertical lower portion is provided as the cap member when the cap member coupled to the liquid discharge port of the long channel member is removed from the liquid discharge port, the upper portion of the circumferential vertical lower portion is fixed while Since the lower portion is hard and extremely low in mobility, the circumferential vertical lower part may be difficult to fall out of the liquid discharge port and may come out with the flow path member. Has a flexible cylindrical coupling portion at the lower end of the circumferential vertical lower portion as a closure member, and since the lower end portion is a free end, the flexible cylindrical coupling portion has extremely high flexibility, so that the liquid discharge port of the elongated flow path member is At the liquid discharge port of the long channel member Less effort due to the flexible action when the cylindrical coupling portion be in the liquid discharge port, even if there is an imbalance in the molding rather advantageous that there be simply taken out from the liquid discharge port.

When preserving a plastic container filled with a viscous liquid, or when transporting a plastic container with a viscous liquid, it is common to close the opening of the plastic container with a cap. However, since the plastic container body of a plastic container is formed from the polyethylene film (water, moisture, and oxygen pass), moisture, moisture, and oxygen which exist in air will infiltrate in a plastic container. When it is left in air for a short time, there is no problem. However, when it is left in air for a long time, hardening reaction proceeds in the case of moisture, oxygen-curable viscous liquid, which is caused by moisture, moisture, and oxygen submerged inside.

The plastic container in the sealed state of the present invention is housed in a moisture or oxygen impermeable envelope body made of, for example, a multilayer sheet-like material containing at least one layer of aluminum thin layer that does not pass moisture, moisture or oxygen. Since the plastic container of the invention is in a sealed state, an unforeseen situation in which the viscous liquid filled in the plastic container contacts and hardens without contacting moisture or oxygen in the air is avoided.

The plastic container in the packaged state of the present invention is a packaged plastic container in the sealed state of the present invention by corrugated cardboard, so that the plastic container in the sealed state does not injure or destroy moisture or oxygen-impermeable envelope body on the way. There is an advantage that it can be safely transported to the site where the application is carried out in a protective packaging.

EMBODIMENT OF THE INVENTION Hereinafter, although embodiment of this invention is described based on FIG. 1 thru | or 23 and FIG. 28 to FIG. 42 in an accompanying drawing, this is shown as an illustration and various modifications are provided unless it deviates from the technical idea of this invention. This is possible.

BRIEF DESCRIPTION OF THE DRAWINGS The cross-sectional explanatory drawing which shows one Embodiment which provided the plastic container of this invention in the inside of a pressurized tank, and shows the state which filled the viscous liquid in the plastic container main body. In FIG. 1, the code | symbol 10 is a plastic container of this invention, and has the plastic container main body 12. As shown in FIG. Although the plastic container main body 12 is formed by a plastic material which is flexible by pressurization, for example, polyethylene, polypropylene, etc., soft polyethylene which is flexible, economical, and easy to shape | mold is especially suitable. An opening 14 is perforated in the upper portion of the plastic container body 12. Inside the plastic container body 12, a viscous liquid 16 is fillable. When the viscous liquid 16 is filled inside the plastic container body 12, when pressure is added from the outside of the plastic container body 12, the plastic container body 12 deforms and shrinks due to pressure. Finally, it is compressed so that the viscous liquid 16 therein can be pressurized and discharged from the opening 14 through the liquid conveying pipe means 20. Teflon (registered trademark) is very suitable as a material of the liquid conveying pipe means 20.

As the viscous liquid 16, a viscous liquid having a viscosity of 5,500 Pa · s / 23 ° C., preferably 10,100 Pa · s / 23 ° C., more preferably 1,560 Pa · s / 23 ° C. is applicable. Especially as the said viscous liquid 16, the curable composition which has adhesiveness is used suitably. As a curable composition which has the said adhesiveness, an adhesive agent, a sealing material, a potting material, etc. are mentioned, for example. The tuck free time (TFT) of the viscous liquid is in a range of 0 to 60 minutes, preferably 0 to 10 minutes, more preferably 0 to 3 minutes. In the present invention, when the viscosity and tuck free time are applied to the viscous liquid in the above range, it may have an effect of less contaminant than the conventional products.

As said curable composition which has adhesiveness, the curable composition of the normal temperature hardening type which can contact with air, such as a moisture hardening type or an oxygen hardening type, and can harden at normal temperature is preferable, Especially moisture-curable adhesives, such as modified silicone type, polyurethane type, and silicone type, are more suitably suited. Is used.

Reference numeral 18 is a long-length flow path member, which is installed in the opening portion 14 to extend inside the plastic container body 12, and forms a flow path of the viscous liquid 16 when the viscous liquid 16 is pressurized and discharged. It is configured to have a function to secure. The elongate flow path member 18 may act to form a flow path of viscous liquid, and various forms can be conceived as will be described in detail below. However, in the example shown in FIG. It has a long flow path part 26a in the circumferential tube body 30a which is integrally installed in the said installation part 24 so that it may extend in the inside of the said plastic container main body 12, and it is 1 in the side wall of the circumferential tube body 30a. Alternatively, a structure in which a plurality of flow path holes 32 are opened is shown. Reference numeral 28 is a lower opening end of the long passage member 18.

The material of the elongate flow path member does not need to be specifically selected as long as it is moldable, but is a plastic material that is easy to bond and has flexibility, such as polyethylene, polypropylene, nylon, fluororubber, silicone rubber, EPDM, SBS, SIS , SEBS, etc. are preferable, and injection molding is easy, and since it becomes inexpensive, olefin resins, such as polyethylene and a polypropylene, are more preferable, and it is especially flexible and inexpensive soft polyethylene is preferable. The long-length channel member is a simple mold structure when the upper mounting portion is completed more than the simple cylindrical structure (rotary body). The flow path member can be manufactured.

In Fig. 1, reference numeral 22 denotes a pressurized tank, which is configured to introduce pressurized air through the air supply pipe 21 through a compressed air supply means (not shown). When the plastic container 10 of the present invention is used, it is used in a state installed in the pressurized tank 22, and as shown in FIG. 2, pressure (for example, pressurization conditions 0.3 to ˜) from the outside of the plastic container 10 is shown. 0.6 MPa) is added to depressurize and deform the plastic container body 12 to discharge the internal viscous liquid 16 from the opening 14 through the liquid conveying pipe means 20, and finally, As shown in FIG. 3, the plastic container body 12 is completely compressed by pressurization to discharge all the viscous liquid 16 contained therein. And the fully compressed plastic container 10 as shown in FIG. 3, in other words, the plastic container main body 12 and the said elongate flow path member 18 can be disposed of in a compressed state without being reused. . For example, when the long flow path member 18 is reused, the long flow path member 18 after use is taken out from the plastic container body 12, and is used for the long flow path member 18 at that time. The viscous liquid adhering is scattered around and becomes the cause of the dirt. However, the present invention has the advantage that the elongated flow path member 18 together with the plastic container body 12 can also be disposed as it is, so that no contamination is generated.

It is explanatory drawing which shows the 1st example of the elongate flow path member used for the plastic container of this invention, (a) is an upper surface explanatory drawing, (b) is sectional explanatory drawing. Fig. 5 is a view showing a long-length flow path member as shown in Fig. 4, (a) is a projection explanatory view showing the whole, and (b) is a projection explanatory view showing only the long part without the upper end part. The elongate flow path member 18 is provided in the opening portion 14 of the plastic container body 12 so as to be shown in Figs. ) And a long flow path portion 26a which is integrally mounted to the mounting portion 24 so as to extend inside the plastic container body 12, and opens a through flow passage 25a at the center thereof.

The upper installation portion 24 has an inner circumferential wall 27 forming a liquid discharge port 23 and an outer circumferential wall 31 installed at a position spaced apart from the inner circumferential wall by a support wall 29. Has) The inner diameter of the inner circumferential wall 27 is a taper portion 33 whose upper portion is larger in diameter than the lower portion and the upper end surface of the inner circumferential wall is inclined inward. The upper end of the outer circumferential wall 31 is bent outward to form an outer circumferential end 35. By attaching the outer circumferential end portion 35 to the outer circumference of the opening portion 14 of the plastic container body 12, the elongate flow path member 18 can be detachably mounted to the opening portion 14. have.

Since the opening part 14 of the said plastic container main body 12 is formed with the wide hole, when the long-length flow path member 18 is attached to the said opening part 14 so that attachment or detachment is possible, the said long-length flow path When the viscous liquid 16 is injected into the plastic container body 12 without binding the member 18, the viscous liquid 16 can be injected with a margin from the opening 14 of the large hole. When the long flow path member 18 is bound to the opening 14 after completion, there is an advantage that the injection operation of the viscous liquid can be performed without any problem. On the other hand, when the elongate flow path member 18 is attached to the opening 14 in advance, the viscous liquid 16 intervenes through the liquid discharge port 23 serving as a narrow width opening of the elongate flow path member 18. In other words, the viscous liquid 16 is injected, and the injection operation is inferior to the injection operation using the opening 14 of the large hole.

The elongate flow path member 18 is such that the viscous liquid 16 remaining inside the plastic container body 12 can be discharged and discharged even in a state where the plastic container body 12 is finally compressed. It is required.

According to the elongate flow path member 18 of this structure, for example, even if the plastic container body 12 is compressed, the opening state 28 at the lower end and the one or the plurality of flow path holes 32 are kept open. It is possible to work so that the discharge flow path of the viscous liquid 16 is secured. In the above configuration, since the flow path hole 32 is opened, the viscous liquid 16 first passes through the flow path hole 32 and then passes through the liquid discharge port 23 and the opening portion 14. The solution is finally discharged through the liquid conveying pipe means 20. In addition, if the flow path hole 32 is sufficiently opened, the opening of the lower end opening part 28 is not essential, and sufficient flow path security can be ensured even if it is closed.

Even in the state where the plastic container body 12 is finally compressed, the structure of the elongated flow path portion which allows the viscous liquid 16 remaining inside the plastic container body 12 to be discharged and discharged is shown in FIG. 4.

It has an elongate flow path part 26a integrally provided in the installation part 24 so that the installation part 24 and the plastic container main body 12 can extend, and the said elongate flow path member 18 It is comprised so that attachment or detachment is possible in the said opening part 14. The upper mounting portion 24 of the elongate flow path member 18 is attached to the opening 14 of the plastic container body 12, and the liquid conveying pipe means is attached to the liquid discharge port 23 of the upper mounting portion 24. (20) is inserted through, and the sealing insertion pressing means 70 of the configuration shown in Fig. 15 makes it very suitable to allow the liquid conveying pipe means 20 to be inserted and pressed into the liquid discharge port 23 in a sealed state. .

The sealing insertion means 70 will be described with reference to FIGS. 15 and 16. The sealing insertion crimping means 70 has a fixing member 72. The fixing member 72 has a cylindrical body 74 having the insertion hole 73 opened in the center thereof, and forms an annular blade portion 75 on the lower outer surface of the cylindrical body 74. The cylindrical body 74 has a lower surface shape of the annular blade portion 75 so as to have a shape corresponding to the upper surface shape of the upper end mounting portion 24 of the elongate flow path member 18 and the annular blade portion ( The upper surface of the (75) to form the receiving end 76 and has a configuration to form a male screw portion 78 on the upper outer surface of the cylindrical body (74). A tapered portion 79 inclined inward is formed at the lower end of the cylindrical body 74. 80 is a cap member with a through hole, which is formed in a central portion of the circular plate 82 to penetrate the through hole 84 that abuts the receiving end 76 and is disposed vertically from the periphery of the circular plate 82. On the inner surface side, a female screw portion 88 which can be screwed onto the male screw portion 14b formed on the outer surface of the cylindrical side wall 14a of the opening portion 14 of the plastic container body 12 is formed. Reference numeral 90 denotes a fixing member, which has a cylindrical member 91 in which a central hole 92 is formed in the center thereof, and a female screw portion 94 is formed in the lower portion of the inner circumferential surface of the cylindrical member 91 as a fastening portion. The upper part of the center hole 92 of the said fixing member 90 is formed so that diameter may become small gradually toward upper part, as shown in FIG.

The shape which makes the said liquid delivery pipe means 20 insert-compress in the sealed state to the said liquid discharge port 23 using the said sealing insertion means 70 is demonstrated. The fixing member 72 is brought into contact with the upper surface of the upper mounting portion 24 of the elongate flow path member 18 so that the center hole 92 of the fixing member 90 and the insertion hole of the fixing member 72 are provided. The liquid conveying pipe means 20 is inserted through the 73 into the liquid discharge port 23 of the upper end mounting portion 24 of the elongate flow path member 18, and the through hole cap member 80 penetrates. The cap member 80 with the through hole is attached to the male screw portion 14b of the cylindrical side wall 14a of the opening portion 14 of the plastic container body 12 with the hole 84 inserted into the receiving end 76.

The screw is connected to the screw, so that the liquid pipe means 20 is sealed to the liquid discharge port 23 of the upper end mounting portion 24 of the elongate flow path member 18. It can be good shovel. In addition, since the diameter of the center hole 92 gradually decreases toward the upper portion as described above, the female screw portion 94 is screwed into the male screw portion 78, and the insertion hole of the fixing member 72 is formed. The upper portion of 73 can be narrowed, and as a result, the liquid conveying pipe means 20 is fastened and fixed, thereby acting to seal between the fixing members 72 with the liquid conveying pipe means 20.

The upper mounting portion 24 of the long channel member 18 shown in FIGS. 15 and 16 is formed from the inner circumferential wall 27 forming the liquid discharge port 23 and the support wall 29 from the inner circumferential wall 27.

Has a structure with a tapered portion 33 inclined inward. On the other hand, the lower end of the cylindrical body 74 of the fixing member 72 has a tapered portion 79 inclined inward. Therefore, when the fixing member 72 is brought into contact with the upper end mounting portion 24 of the elongate flow path member 18, as shown in Fig. 15, the upper taper portion 33 and the cylinder of the inner circumferential wall 27 are shown. The lower taper portion 79 of the base 74 abuts on each other to form a structure that can be sealed.

As the material of the fixing member 72, 6-nylon is preferable in terms of toughness, and high density polyethylene (HDPE) is suitably used in terms of easily wiping off the adhered viscous liquid. As the material of the cap member 80 with the through hole, hard polyethylene is used, and as the material of the fixing member 90, polyacetal having lubricity is preferable.

In addition, in the example of FIG. 15, although the lower end part of the liquid delivery pipe means 20 is set so that it may become one with the lower surface of the cylindrical main body 74 of the fixing member 72, the liquid delivery pipe means 20 is thus performed. Due to the lower end of the fixing member 72 is configured so as not to be a free end vertically downward from the lower end, since the viscous liquid 16 from the lower end of the liquid conveying pipe means 20 is limited, the contamination is reduced There is this. The liquid feeding pipe means 20 may be vertically lowered to the extent that the lower end of the liquid feeding pipe means 20 is inserted into the liquid discharge port 23 of the flow path member 18, but the smaller the vertical length is, The occurrence of dirt becomes less. Also in the following example, although the lower end part of the liquid delivery pipe means 20 is set like FIG. 15, description is abbreviate | omitted again.

The combination of the upper surface shape of the upper end attachment part 24 of the long-length flow path member 18 shown in FIG. 15, and the lower surface shape of the fixing member 72 can be considered other than the example of FIG. It explains in detail.

The structural example shown in FIG. 17 is the upper end taper part 33 of the inner peripheral wall 27 of the upper end installation part 24 of the elongate flow path member 18, and the lower end taper of the cylindrical main body 74 of the fixing member 72. As shown in FIG. While the inclination direction of the taper of the portion 79 is reversed from those in FIG. 15, the inner diameter of the inner circumferential wall 27 is the same as that in FIG. 15 except that the upper portion and the lower portion have the same diameter. To have. In this case, in contrast to the case of FIG. 15, when the fixing member 72 is brought into contact with the upper end attaching portion 24 of the elongate flow path member 18, as shown in FIG. 17, the inner circumferential wall ( The upper tapered portion 33 of the 27 and the lower tapered portion 79 of the cylindrical body 74 abut each other to form a structure capable of being sealed.

It is suitable for screwing, and differs in that it is carried out through the auxiliary annular member 95 described above. In addition, in the structure example of FIG. 17, the insertion taper part 74a is formed in the outer surface of the upper end part of the cylindrical body 74 of the fixing member 72, and the cylindrical body is formed in the center hole 92 of the fixing member 90. FIG. Although the tip portion of the 74 is configured to be easily inserted, in the structural example of FIGS. 20 and 21, the upper end portion of the cylindrical body 74 of the fixing member 72 has an annular taper of the lower end portion of the auxiliary annular member 95 described above. In order to receive the blade part 98, the receiving taper part 74b is formed in the inner surface of the upper end part of the said cylindrical main body 74. As shown in FIG. In addition, an inner circumferential end portion 91a is formed at the upper inner circumferential portion of the cylindrical member 91 of the fixing member 90 so that the auxiliary annular member 95 is inserted into the center hole 92 of the fixing member 900. The inner circumferential end portion 91a is configured to abut on the upper portion of the annular tapered blade portion 98. The auxiliary annular member 95 may also 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 into the center hole 92 of the fixing member 90 is shown. It can be used as long as it is a member which completes this, and a one-touch seam mechanism can also be applied, The example is shown in FIG. Referring to Fig. 21C, reference numeral 120 denotes a fixing member that prepares and fixes a one-touch seam mechanism, and has a stepped cylindrical member 122. A center insertion hole 124 is disposed in the stepped cylindrical member 122. A cylindrical portion 126 having a small diameter is formed at a lower portion of the stepped cylindrical member 122, and a cylindrical end portion 128 having a large diameter is provided at an upper portion thereof. A female screw portion 130 is formed on the inner circumferential surface of the cylindrical portion 126 having a small diameter.

Reference numeral 136 denotes a sleeve, which serves to press the lock claw 134. Reference numeral 138 presses the sleeve 136 with the pressure block. By setting it as such a structure, the liquid conveying pipe means 20 is inserted in the sealed state in the center insertion hole 124 of the fixing member 120 provided with the one-touch joint mechanism. In addition, the structure of the one-touch seams is known in various ways, and in addition to the above-described structure, the structures of the one-touch seams described in the publications of Japanese Patent Application Laid-Open No. 1-206196, Utility Model No. 4-35669, Utility Model Registration No. 2575755, Utility Model Registration No. 2524012, etc. You can also apply

By the above configuration, the operation of the coating device of the present invention will be described. First, when compressed air is supplied into the pressurized tank 22 through the air supply pipe 21 from the compressed air supply means 62, as shown in FIG. 1, the viscous liquid is installed in the pressurized tank 22 at the same time. The plastic container 10 that is being filled with the full state of 16 is pressurized. Next, as shown in FIG. 2, the plastic container 10 is deformed and deformed by pressurization so that the viscous liquid 16 therein discharges from the plastic container 10 through the long channel member 18. As shown in FIG. do. Then, the discharged viscous liquid 16 is ejected from the application nozzle means 64 via the liquid conveying pipe means 20, and the viscous liquid 16 is applied to a predetermined portion. In this coating operation, in the state where all the viscous liquid 16 is discharged and used, as shown in FIG. 3, the said plastic container 10 is compressed by pressurization. At this point, all of the viscous liquid 16 filled in the plastic container 10 is not pressurized and discharged, and only the long channel member 18 remains in the compressed plastic container body 12. Becomes Then, as shown in FIG. 22, the lid 22b is removed from the tank body 22a of the pressurized tank 22, and then the used plastic container 10, that is, the plastic container body 12, is used. ) And the combination of the plastic container body 12 and the elongated flow path member 18 of the fixing member 72, the cap member 80 with the through hole, the fixing member 90 and the liquid conveying means 20. 22 and 23, and the coalescing of the plastic container body 12 and the elongate flow path member 18 left in the tank main body 22a is discarded. When the long flow path member 18 is removed from the compressed plastic container 10 and attempted to be reused, the viscous liquid adhering to the long flow path member 18 scatters and causes contamination of the work site. Although this occurs, in the present invention, the compressed plastic container 10, that is, the plastic container body 12 and the elongated flow path member 18 are formed to be disposed of, so that the contaminated plastic container 10 is discarded as it is. There is this.

Moreover, in the apparatus which does not install the elongate flow path member of this invention in the plastic container 106, the liquid conveying pipe means 110 is extended in the plastic container 106, and it enters in the viscous liquid 112, and is used. In this case, since the flow path is simply closed when the tip of the liquid delivery pipe means 110 is blocked, an accident may occur such that the entire amount of the viscous liquid 112 in the plastic container 106 is not discharged. Even if the viscous liquid 112 is discharged in its entirety, as shown in FIG. 24, the cover 102b is removed from the tank body 102a of the pressurized tank 102, and the liquid conveying pipe means 110 is removed from the plastic container 106. When it is pulled out, the viscous liquid 112 attached to the liquid conveying pipe means 110 is scattered. To prevent this, it is necessary to wipe off the viscous liquid 112 from the liquid conveying pipe means 110 with a rag. have. In addition, although it is good to be able to wipe off at that time, if repeated, the gaseous substance of the viscous liquid 112 (for example, hardened adhesive) will be attached to a liquid conveying means, and the liquid conveying pipe means 110 will be attached again. When used, this gaseous substance is likely to be incorporated into the viscous liquid 112, causing failure of each member such as the application nozzle means, etc., and thus applying the viscous liquid 112 (for example, an adhesive). Problems occur such as missing. In particular, in the moisture-curable adhesive, there is a problem that gas of the adhesive tends to come out, and normal operation of each member such as the application nozzle means and the like does not occur.

More specifically, in a pressure tank used when applying a viscous liquid, for example, a moisture curable adhesive, the pressure is generally about 0.3 to 0.6 MPa. Therefore, in order to withstand the pressure and at the same time maintain a high hermeticity, the lid of the pressurized tank is formed so as to have a weight (for example, a weight of about 6 to 10 kg) in thickness, so that the conversion work of the plastic container is usually It is performed by three workers (one performs the replacement of the plastic container including the detachment of the long liquid conveying means by the other two while lifting a cover). In the case of replacing the plastic container containing the viscous liquid even after the end of the coating operation, as shown in Fig. 24, the old plastic container is removed from the plastic container except for the liquid conveying means, and then the new plastic container is removed from the plastic container. Is stored in a pressurized tank, and the length of the liquid conveying pipe means needs to be inserted into the plastic container, and dirt caused by viscous liquids, for example, adhesives, scatters frequently from the tip of the liquid feeding pipe means. It will occur as. In addition, in the case of using a moisture-curable adhesive having a fast curing speed (curing in 3 to 10 minutes) as a viscous liquid, particularly quick work is required, the work is difficult.

Various problems in the case of using only such a conventional liquid conveying pipe means are all solved by the use of the plastic container 10 provided with the elongate flow path member 18 of this invention. For example, the above-mentioned conversion operation of the plastic container was performed by three people as mentioned above. In applying the plastic container of the present invention, two people (one of the remaining long liquid transport pipes while one is lifting the lid) Replacement of the plastic container including the removal and insertion of the means) can be performed. The plastic container, the elongate flow path member and the application device of the present invention effectively solve the above problems, which have been considered as a big problem in the art in the art, and have a great advantage. As one means of eliminating the problem that the viscous liquid 16 is scattered from the tip of the liquid delivery pipe means 20 and causes dirt, the liquid delivery pipe means 20 as described in the description of the example of FIG. 15. It is effective to adopt a configuration in which the tip of the tip does not protrude downward from the fixing member 72.
