Detailed Description of the Invention

[0001]

An object of the present invention relates to relates to a preparative attitude method suitable viscous fluid to retrieve the viscous fluid having a high viscosity such as an adhesive or sealing agent from the container body.

[0002]

2. Description of the Related Art Since adhesives and sealing agents used in automobile assembly plants are consumed in large amounts, they are usually filled in large cylindrical containers such as drums and supplied to various facilities, and pumps are used for drums. It is configured to sequentially take out the required amount from. As a viscous fluid filling container filled with a viscous fluid such as an adhesive or a sealing agent, for example, in Utility Model Registration No. 2545889, a shape that conforms to the inner surface of the body portion of the container body and follows the lower surface of the follower plate of the pump Of the viscous fluid, which has an outlet for the viscous fluid and which is closed by a lid member made of a film or a sheet. A viscous fluid-filled container mounted on a surface is described. Further, this publication describes, as a follower plate of a pump, a recess formed in the lower surface in a stepwise manner toward the outlet side in order to prevent air from remaining near the pressure plate. In addition, as a container of this type, a viscous fluid such as an adhesive or a sealing agent is filled in a flexible inner bag so that the container body can be easily reused, and this is loaded into the container body, A container configured to prevent adhesion of a viscous fluid to the inner surface of the container has been put into practical use.

[0003]

By the way, in the viscous fluid-filled container described in the above publication, even if the follower plate is moved to the lowermost position and the viscous fluid is taken out to the maximum, 7-10% of the total weight is obtained. There is a problem that the viscous fluid cannot be used because it remains in the container body or protrudes from the gap between the pressure plate that pressurizes the viscous fluid and the container body. The applicant of the present invention diligently studied in order to reduce such a residue or protrusion of the viscous fluid as much as possible, and found that the mechanism of occurrence of these problems is as follows.

(1) In the container described in the above publication, since the recess is formed on the lower surface side of the follower plate and the pressurizing plate is also formed so as to fit with the recess, the follower plate and the pressurizing plate are provided in the container main body. The viscous fluid remains in the concave portion of the pressure plate even when the viscous fluid is pushed to the lowermost end. (2) In a cylindrical container such as a drum can, a winding stop is formed at the connecting portion of the main plate portion and the body portion, and the main plate portion is disposed slightly above the lower end portion of the body portion to keep the container on a flat floor. A constant gap is formed between the main plate portion and the floor surface while being placed on the surface. Therefore, when the viscous fluid vibrates in the vertical direction during transportation and a large load is applied to the ground plate, or when the viscous fluid is pressurized by a pump to take out the viscous fluid, the ground plate moves downward. It deforms in a protruding shape to the side, and the viscous fluid remains by that amount.

(3) When the viscous fluid is filled in the inner bag, in addition to the problems of (1) and (2) above, the viscous fluid is taken out by lowering the follower plate and the pressure plate. Even when the outer peripheral part of the inner bag is folded and the follower plate and pressure plate are pushed to the lowermost position of the container body, a gap corresponding to the thickness of the folded inner bag is formed between the pressure plate and the main plate part of the container body. Are formed, and the viscous fluid remains in the gap. (4) When filling the inner bag with a viscous fluid, when the pressure plate moves to a position corresponding to an annular zone formed in the middle of the container body, the gap between the pressure plate and the container body becomes large. The inner bag protrudes from the gap, and a large amount of viscous fluid remains in the inner bag.

An object of the present invention is to <br/> provide attitude method preparative viscous fluid to be not become viscous fluid used may be minimized by the residual.

The viscous fluid is taken out from the outlet through pressurization through the pressure plate . At this time, the base plate portion of the container body tends to be deformed downwardly by the pressure applied to the viscous fluid. However, since the deformation of the base plate part is restricted by the external deformation restricting plate, it is possible to prevent the viscous fluid from remaining due to the base plate part being deformed to project downward.

Further, in the second method, for example, an external deformation regulating plate may be provided on the floor surface below the follower plate of the viscous fluid take-out station, and the container body may be set on the external deformation regulating plate. It is preferable because it can be used as it is and the configuration of the take-out device need not be changed. In addition, when the main plate portion is deformed during transportation, etc., by pressing the body portion of the container main body downward with the container main body placed on the external deformation restricting plate, the external deformation restricting plate causes the main plate portion to be pressed downward. It is also possible to forcibly restore the deformation of. That is, the main plate

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. <First Example> As shown in FIG. 1, a viscous fluid-filled container 1 includes a container body 2 having a substantially cylindrical shape with a bottom, a canopy 3 for closing an upper opening of the container body 2 in an airtight manner, and a flexible container. A filling body 6 in which a viscous fluid 5 having a high viscosity such as an adhesive or a sealing agent is filled in the inner bag 4
And an internal deformation regulating plate 7 mounted between the base plate portion 11 of the container body 2 and the filling body 6. However, this viscosity
The fluid filling container 1 does not constitute the present invention.

The container body 2 includes a substantially cylindrical body portion 10,
A substantially disk-shaped main plate portion 1 fixed to a portion near the lower end of the body portion 10.
1 and the main plate portion 11 and the body portion 10 are airtightly coupled to each other at the winding portion 12. The body portion 10 and the base plate portion 11 are each manufactured using a metal plate such as a strip steel plate. The main plate portion 11 is provided in the vicinity of the lower end of the body portion 10, and is configured such that a constant gap is formed between the main plate portion 11 and the floor surface when the container body 2 is placed on a flat floor surface. Has been done. An annular zone 13 formed of an annular bulge projecting outward is formed in the middle of the body 10, and is reinforced so that the middle of the body 10 does not bulge due to the weight of the contents. If the volume of the container body 2 is relatively small, the ring zone 13 can be omitted. Further, the container body 2 is preferably a drum can having a bottom and a substantially cylindrical shape because it can be obtained at low cost and is excellent in strength, but it can be formed into a bottomed prismatic shape.

It is preferable that the canopy 3 is detachably fitted and screwed to the body 10 or fixed in an airtight manner by bolting or the like.

The inner bag 4 may be made of any material as long as it is made of a soft film material that can be crushed into small pieces, and may be a film material having a single-layer structure or a multi-layer structure made of only a resin film. Alternatively, a film material having a multilayer structure in which a metal foil such as an aluminum foil is laminated between resin films may be used. In this embodiment, a film material having a three-layer structure or a four-layer structure in which aluminum foil is laminated between resin films is used, and this film material is formed into a bag shape by heat sealing or ultrasonic sealing.
As a material for the resin film, a heat-sealable thermoplastic resin such as polyethylene, polyester, polypropylene, nylon can be preferably used. The inner and outer resin films may be made of the same kind of material, but since the usage conditions are different between the inner surface side and the outer surface side, it is preferable to use a resin film made of a material according to the usage conditions.
For example, when the inner bag 4 is filled with a moisture-curable sealing material as the viscous fluid 5, a polyethylene or polypropylene film that does not deteriorate or adhere due to contact with the sealing material is used as the resin film on the inner surface side, and the outer surface As the resin film on the side, it is desirable to use a polyester or nylon film with emphasis on strength and gas barrier properties.

In this viscous fluid filling container 1, the inner bag 4 is filled with the viscous fluid 5, the opening of the inner bag 4 is closed, and then the filling body 6 filled with the viscous fluid 5 is loaded into the container body 2. However, since air remains near the opening of the inner bag 4 at this time, in the case of a viscous fluid composed of a moisture-curable composition that reacts with moisture in the atmosphere, the opening of the inner bag 4 is changed. The filling body 6 may be inverted and housed in the container body 2 so that the container is located on the bottom side of the container body 2. However, when the viscous fluid 5 to be filled does not deteriorate due to contact with air, the inner bag 4 is generally filled with the viscous fluid 5 with the inner bag 4 loaded in the container body 2. Is enough.

The internal deformation regulating plate 7 is composed of a substantially flat metal plate or synthetic resin plate which is formed in a size that can fit inside the body portion 10 of the container body 2 with substantially no space, and is a follower plate of the pump. The bottom plate portion 11 is prevented from being deformed in a downwardly protruding shape when the filling body 6 is pressurized to take out the filled viscous fluid 5. The internal deformation regulating plate 7 may be a solid member or a hollow member as long as it is a plate-shaped member having strength and rigidity that receives at least a pressure applied to the filling body 6 and hardly deforms. It may be. Also,
For example, like the internal deformation regulating plate 20 shown in FIG. 2, it is also possible to adopt a structure in which reinforcing rib portions 21 are integrally formed in a lattice shape on the lower surface side.
The internal deformation regulating plate 7 can be arranged inside the bottom of the inner bag 4.

A paragraph 15 is formed in an annular shape on the outer peripheral portion on the upper surface side of the internal deformation regulating plate 7, and the viscous fluid 5 is used up by moving the pressure plate 32 to the lower end position of the container body 2 as described later. When folded, substantially the entire outer peripheral portion of the folded inner bag 4 is housed in the paragraph portion 15. However, this paragraph may be formed on the outer peripheral portion on the lower surface side of the pressure plate 32, or may be formed on the internal deformation regulating plate 7 and the pressure plate 32, respectively. In addition, the internal deformation regulating plate 7 is attached to the body portion 10 of the container body 2.
Smaller than the inner diameter of the internal deformation regulating plate 7
A space for accommodating the inner bag 4 may be formed between the body part 10 and the body part 10. However, in this case, the base plate portion 11 of the container body 2 and the internal deformation regulating plate 7 are positioned via the concave-convex fitting portion or the like.

Next, the take-out device 30 for the viscous fluid 5 will be briefly described. As shown in FIG. 3, the take-out device 30 is
The follower plate 31 having a well-known structure, a driving means (not shown) for driving the follower plate 31 in the vertical direction, and a pressure plate 32 interposed between the follower plate 31 and the filling body 6 to press the filling body 6 are provided. .

The pressure plate 32 is a substantially disk-shaped member that is fitted in the body portion 10 of the container body 2 in a vertically movable manner with substantially no space therebetween, and does not bend at least when the viscous fluid 5 is pressed. It is composed of a metal plate or a synthetic resin plate having strength and rigidity. The pressurizing plate 32 may be omitted and the follower plate 31 may be directly brought into pressure contact. Further, the pressure plate 32 may be integrally fixed to the lower surface of the follower plate 31. Further, in the present embodiment, the lower surface of the pressure plate 32 is formed into a substantially flat shape, but the lower surface of the pressure plate 32 is provided along the lower surface of the follower plate on the outlet 33 side as in the conventional pressure plate. You may form a recess which becomes deep continuously or gradually as it goes to. However, in this case, as described above, the shape of the upper surface of the internal deformation regulating plate 7 is formed into a mountain shape that can be superposed on the lower surface of the pressure plate 32 without any gap.

At the center of the pressure plate 32, the viscous fluid 5
Of the follower plate 31 is integrally formed with a rod portion 34 extending upward, and the follower plate 31 and the rod portion 34 are formed with a flow passage 35 communicating with the outlet port 33. ing. Then, the driving means moves the pressure plate 32 together with the follower plate 31 downward to press the filling body 6, so that the viscous fluid 5 filled in the filling body 6 passes through the outlet 33 and the flow passage 35 in a required amount. It is configured so that it can only be taken out.

Next, a method of taking out the viscous fluid 5 from the viscous fluid-filled container 1 using the take-out device 30 will be described. First, as shown in FIG. 3, the canopy 3 is removed from the viscous fluid filling container 1, and the pressure plate 32 is placed on the upper side of the filling body 6.
Is placed, the follower plate 31 is set in the viscous fluid-filled container 1, and the lower half portion is fitted into the body portion 10 of the container body 2.

Next, the inner bag 4 is incised at a position corresponding to the outlet 33 of the pressure plate 32 to open the filling body 6, and the follower plate 31 of the pump is placed on the pressure plate 32 and the follower The flow passage 35 of the plate 31 and the outlet 33 of the pressure plate 32 are communicated with each other. However,
As the inner bag 4 of the filling body 6, a through hole is formed in the central portion of the upper surface, and a sealing film that hermetically seals the through hole is fixed to the outer surface of the inner bag 4 by heat sealing, ultrasonic sealing, or the like. Adopting one, removing the sealing film and filling body 6
May be opened.

Then, with the viscous fluid filling container 1 set in the take-out device 30, the pressurizing plate 32 is lowered together with the follower plate 31 if necessary, and the filling member 6
The inner pressure of the inner bag 4 is increased to remove the inner bag 4 from the outlet 33 and the flow passage 35.
The viscous fluid 5 is sequentially discharged via the. At this time, the self-weight of the filling body 6 and the pressure applied by the follower plate 31 act on the internal deformation regulating plate 7, but since the internal deformation regulating plate 7 having sufficient strength and rigidity is adopted, the container body 2 The bottom plate portion 11 is prevented from being deformed in a downward protruding shape. In addition, viscous fluid 5
Since the inner bag 4 is filled with the pressure plate 32, the pressure plate 32 reaches the annular zone 13 and the pressure plate 32 and the container body 2
Even if a gap is formed between the body parts 10, the viscous fluid 5 does not remain.

In this manner, the necessary amount of the viscous fluid 5 is sequentially taken out, and when the follower plate 31 and the pressure plate 32 are moved to the lowermost side, the outer peripheral portion of the inner bag 4 is compactly folded in the paragraph 15. The pressure plate 32 and the internal deformation regulating plate 7 are in close contact with each other with the upper surface portion and the lower surface portion of the inner bag 4 sandwiched therebetween, and the viscous fluid 5 is present between the pressure plate 32 and the internal deformation regulating plate 7. Will hardly remain. In addition, since the viscous fluid 5 is filled through the inner bag 4 in this way, the viscous fluid 5 is prevented from adhering to the inner surface of the container body 2, and after the viscous fluid 5 is completely used up By removing the bag 4, the container body 2 and the internal deformation regulating plate 7 can be reused as they are.

<Second Embodiment> Next, a second embodiment in which the configurations of the viscous fluid filling container 1 and the take-out device 30 are partially changed will be described. still,
The same members as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Viscous fluid filling container 1 of the second embodiment
As shown in FIG. 4, A has the same configuration as that of the first embodiment except that the internal deformation regulating plate 7 is omitted.
However, it indicates to the viscous fluid-filled container 1A in FIG. 4 is of a state of detaching the canopy 3.

In the take-out device 30A, an external deformation regulating plate 7A for preventing deformation of the main plate portion 11 of the container body 2 is arranged on the floor surface below the follower plate 31 of the pump, and in place of the pressure plate 32, The structure is the same as that of the first embodiment except that the pressure plate 32A having the paragraph 40 for accommodating the folded inner bag 4 formed on the outer peripheral portion on the lower surface side is used. In the second embodiment, when a concave portion is formed on the lower surface of the pressure plate 32A as described in the first embodiment as in the conventional case, the viscous fluid 5 is formed in the concave portion.
However, the lower surface of the pressure plate 32A is preferably flat. The take-out device 30A of the second embodiment itself does not constitute the present invention.
Yes .

The external deformation regulating plate 7A is a container body 2

Main body projection 41 is formed, and a substantially flat receiving surface 42 is formed on the upper surface of the main body projection 41.
A paragraph portion 43 is formed on the outer peripheral portion on the upper surface side of A, and the depth of the paragraph portion 43 is set to be substantially the same as the height of the winding tightening portion 12. As long as the external deformation regulating plate 7A has a substantially flat receiving surface 42, the external deformation regulating plate 7A may be formed of a solid member, like the internal deformation regulating plate 7 of the first embodiment. A hollow member may be used, or a rib portion may be arranged on the lower surface side. It is also possible to employ a deformation regulating plate having a relatively large through hole, for example, a through hole formed inside the rib portion 21 in FIG.

The assembling of the viscous fluid filling container 1A to the take-out device 30A is carried out by placing the base plate portion 11 of the container body 2 on the receiving surface 42 of the main body projection 41 so that the viscous fluid filling container 1A is externally deformed. It is assembled in the same manner as the first embodiment except that it is set on 7A.
As the take-out device 30A, the external deformation regulation plate 7A is used.
The viscous fluid-filled container 1A set above is equipped with a cylinder that presses the body portion 10 downward, and the deformation of the main plate portion 11 of the container body 2 during transportation is restored to a flat original state. You may let me.

When the filling plate 6 is pressed by the pressure plate 32A to take out the viscous fluid 5, the base plate portion 11 of the container body 2 tends to deform downward, but the bottom surface side of the base plate portion 11 is deformed. External deformation regulation plate 7A
Is arranged, deformation of the main plate portion 11 is restricted,
The viscous fluid 5 is prevented from remaining due to the deformation of the base plate portion 11. Further, the outer peripheral portion of the folded inner bag 4 is housed in the paragraph portion 40 of the pressure plate 32A, and the pressure plate 32A and the base plate portion 11 are in close contact with each other with the upper surface portion and the lower surface portion of the inner bag 4 interposed therebetween. By this, the pressure plate 32
The viscous fluid 5 is prevented from remaining between A and the base plate portion 11. Further, in the second embodiment, the existing one can be adopted as it is as the viscous fluid filling container 1A, and also regarding the take-out device 30A, the shape of the pressure plate 32A is changed and the external deformation regulating plate 7A is simply provided. Since it can be changed easily, it can be easily implemented using existing equipment.

<Third Embodiment> Next, a third embodiment in which the configurations of the viscous fluid filling container 1 and the take-out device 30 are partially changed will be described. still,
The same members as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Viscous fluid filling container 1 of the third embodiment
B is a viscous fluid 5 with the inner bag 4 omitted, as shown in FIG.
Is directly filled in the container main body 2 and the internal deformation regulating plate 7 is replaced with an internal deformation regulating plate 7B having no paragraph 15 on the outer peripheral portion, as in the first embodiment. It is configured. However, the internal deformation regulation plate 7
If an internal deformation regulating plate 20 having a recess as shown in FIG. 2 is adopted as B, viscous fluid remains in the recess, so it is preferable to use a solid member. The viscous fluid filling container 1B shown in FIG. 5 is in a state in which the canopy 3 is removed and a pressure plate 32B and a follower plate 31 of the pump, which will be described later, are set. However, the viscous fluid filling container 1B itself does not constitute the present invention. Further, the take-out device 30B itself described later constitutes the present invention.
It does not come.

The take-out device 30B has the same construction as that of the first embodiment except that a pressure plate 32B having a seal ring 45 which is always in close contact with the body portion 10 of the container body 2 is provided on the outer peripheral portion. . However, like the conventional pressure plate, a recess may be formed on the lower surface of the pressure plate 32B, which becomes deeper continuously or stepwise toward the outlet 33 side. In this case, the shape of the upper surface of the internal deformation regulating plate 7B is formed into a mountain shape that can be superposed on the lower surface of the pressure plate 32B without any gap, and the pressure plate 32
It is preferable that the viscous fluid 5 does not remain between the internal deformation regulation plate 7B and the internal deformation regulation plate 7B.

When the viscous fluid filling container 1B is assembled to the take-out device 30B, the seal ring 45 is attached to the body portion 10 when the pressure plate 32B is set on the upper side of the filling body 6.
It is assembled in the same manner as in the first embodiment except that it is fitted to the inner surface of.

When the filling body 6 is pressed by the follower plate 31 of the pump to take out the viscous fluid 5, the load acting on the viscous fluid 5 is received by the internal deformation regulating plate 7B, and the base plate portion 1 of the container body 2 is received.
The downward deformation of 1 is prevented, and the viscous fluid 5 is prevented from remaining due to the deformation of the main plate portion 11. In addition, since the viscous fluid 5 remains less, it is easy to reuse the container body. The pressure plate 3 of the first embodiment
Also for the outer peripheral portion of No. 2, as in the third embodiment, it is preferable to provide a seal ring 45 on the outer peripheral portion of the pressure plate 32, which is in pressure contact with the inner surface of the body portion 10 of the container body 2. By providing such a seal ring 45, it is possible to suppress the problem that the inner bag 4 protrudes from the gap between the pressure plate 32 and the body portion 10 of the container body 2 and the viscous fluid 5 remains in the inner bag 4. Can be prevented. In particular, since the gap between the pressure plate 32 and the body portion 10 in the ring portion 13 becomes large, the inner bag easily sticks out.
Is preferably provided.

However, also in the third embodiment, as in the second embodiment, the internal deformation regulating plate 7B is omitted from or combined with the viscous fluid filling container 1B and below the follower plate 31 of the take-out device 30. The external deformation restricting plate 7A may be provided on the floor surface of and the external deformation restricting plate 7A may restrict the deformation of the main plate portion 11 of the container body 2. Further, in the present embodiment, the inner deformation regulating plate is loaded in the bottom portion of the container body 2, or the outer deformation regulating plate is arranged on the lower floor surface of the follower plate 31 of the takeout device. May be loaded into the bottom of the device and placed on the floor below the follower plate 31 of the unloading device.

According to the viscous fluid extraction method of the present invention, the base plate portion is deformed in a downward protruding shape with a simple structure in which an external deformation restricting plate for restricting the deformation of the base plate portion of the container body is provided. By suppressing the residual of viscous fluid due to
