DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray booth,
More particularly, the present invention relates to a spray booth capable of performing a coating operation while preventing a material from scattering around when spraying a spray type adhesive or a paint on an object to be coated.

[0002]

2. Description of the Related Art Heretofore, there has been known a spray-type adhesive in which a suitable synthetic rubber or acrylic rubber or the like is dissolved in an organic solvent and sealed with a pressurized gas. This type of adhesive can be applied by spraying the material onto paper or the like as an object to be coated, but particles of the adhesive component contained in the sprayed gas are scattered in the air. Since it floats, it sticks to the floor and other surroundings, causing stickiness and causing soiling of the floor and the like.

In view of the above, a disposable spray booth has been proposed in which the above-mentioned coating operation can be performed in a booth having a space capable of accommodating an object to be coated, and the spray gas which causes stickiness is prevented from being scattered. (See, for example, Japanese Utility Model Laid-Open No. 5-51472). This one is
A hollow box made of cardboard or the like having an opening formed in the upper inclined direction, a vent hole formed in a peripheral wall portion of the box, and a nonwoven fabric provided to close the vent hole And a filter.

[0004] The spray booth in this proposal proposes spraying a material from an opening in a state in which an object to be coated is accommodated in a box body to prevent the gas sprayed on the peripheral wall of the box body from scattering. It is possible to release the gas retained in the box through the filter, thereby allowing an adhesive component or the like to adhere to the filter.

[0005]

However, in such a spray booth, the opening formed in the upper portion of the box is always largely open in the inclined direction, and the opening is positively closed. Because it is a structure without any means, it is easy for a large amount of gas containing particles such as sprayed adhesive and coating components to flow out from the opening, and the expected material scattering prevention effect is not necessarily sufficient. Is hard to say. Therefore, there is a disadvantage that it is not possible to effectively avoid stains, stickiness, and the like on the floor and the like due to the adhesion of particles such as adhesive components around the spray booth.

In order to solve such inconveniences, it is conceivable to set the above-mentioned opening small. However, if the opening area is simply reduced, the work to be set at a predetermined coating position in the spray booth is considered. In addition to the drawbacks, the drawbacks are also caused, and it is difficult to access the object to be sprayed with the spray.

In general, since particles such as adhesive components contained in the spray gas are heavier than air, the spray gas losing the spray pressure and staying in the box has a tendency to gradually settle. In the booth, the filter is only partially provided on the peripheral wall, and it is not possible to release the settled gas easily from the bottom wall. It is hard to say that the configuration can achieve release.

[0008]

SUMMARY OF THE INVENTION The present invention has been devised in order to improve the disadvantages of the prior art, and has as its object to provide an opening for allowing easy access of a set of objects to be coated and spraying. It is also possible to suppress gas release from the opening, to catch particles such as adhesive components during gas release during or immediately after spraying, and to positively release gas retained inside from the bottom side. It is to provide a spray booth that can be used.

Another object of the present invention is to limit an area that is soiled by the coating operation to a part of components, and to avoid disposable as a whole by replacing only the components. It is to provide a spray booth that can be used for a long time.

[0010]

In order to achieve the above object, the present invention provides a booth body having a predetermined space in which a coating object is accommodated, and scattering of a material sprayed on the coating object is performed. In the spray booth that can be prevented, the lid is connected to be openable and closable on substantially the same plane as the top wall of the booth main body, and an opening located on a substantially vertical plane in the closed state is formed in the booth main body, In addition, a filter is provided on the bottom side of the booth body.

In the spray booth, a configuration is adopted in which a porous member on which an object to be coated can be placed is disposed inside the booth main body, and the filter is provided below the porous member. .

Further, the booth main body is formed as an open bottom type, and the filter is disposed at a position spaced upward from a mounting surface of the booth main body via a spacer.

Further, the filter can be provided at a position separated from the installation surface of the booth main body via a spacer, and the spacer is provided at a closed loop frame capable of receiving the booth main body and at a plurality of locations on the inner surface of the frame. And an engaging portion that engages with the lower side of the booth body. The frame and the engaging portion are provided so as to be flat and foldable. In addition, a configuration in which a filter is additionally provided on the lid body is adopted.

Further , in a spray booth in which an object to be coated is accommodated in a booth main body having a predetermined space formed therein and a material sprayed on the object to be sprayed can be prevented from being scattered, an opening is formed at one end side. A booth body having a hole formed in the bottom wall, a cover body provided to be able to open and close the opening, and a spacer connected to the booth body and separating the bottom wall upward from the installation surface. A configuration is adopted in which a filter is provided in a region where the hole is formed, while a filter having a working hole is provided in a predetermined position on the lid body. It is a thing. Here, in the booth main body, a porous member on which the object to be coated can be placed is disposed at a position separated from the bottom wall above.

A booth having an opening at one end side, wherein an object to be coated is accommodated in a booth body having a predetermined space formed therein, and the material sprayed on the object can be prevented from scattering. A main body, and a bag which is removably mounted in the booth main body and is provided so as to be capable of accommodating an object to be coated therein.

In both cases, the booth body and lid are integrally molded.
The lid is opened by operating a pedal attached to the booth body.
It can be configured to be provided so as to be able to be closed.

[0017]

When applying an adhesive or paint to an object using the spray booth of the present invention, the object is set in the booth body, and the spray nozzle is directed at the object to apply the material. This is done by spraying. At this time, the spray operation can be performed at a position where the spray is exposed inside the booth main body through the opening or the working hole.

Of the sprayed materials, the gas sprayed around the object to be coated and the adhesive components and the like contained in the gas are filled in the booth main body and tend to flow out. The gas is externally released through the lid and / or the filter provided on the bottom side.
Therefore, when the gas passes through the filter, an adhesive component or the like adheres to the inner surface of the filter and is hardly released to the outside. When the filter is clogged so that a certain filter effect cannot be maintained, it is sufficient to replace the filter with a new one.

Further, in the configuration in which the object to be coated can be placed on the porous member disposed in the booth main body, the spray gas can be settled down gently while attenuating the reflected pressure of the gas. Promote splash prevention.

In a spray booth in which a bag is provided in the booth body, an adhesive component or the like contained in the gas after spraying fills the inside of the bag, but closes the opening side of the bag after the spraying is completed. As a result, gas can be sealed in the bag, and subsequent scattering of the outside can be effectively prevented. In the sealed state, the particles such as the adhesive component will gradually settle and adhere to the inner surface of the bag, and will not scatter from the open side of the bag even when the bag is opened next time. Then, when the inner surface of the bag is considerably contaminated by intermittent spraying, only this bag is replaced with a new bag.

In the spray booth in which the bag is made of a material having a filter function, the gas retained inside the bag after closing the opening side of the bag is spontaneously discharged to the outside through the fine holes of the bag itself. That is, at this time, particles such as an adhesive component can be attached to the inner surface of the bag.

In the configuration in which the object to be coated can be placed on the porous member, the spray pressure of the material is gradually attenuated because the porous member is located at a position separated from the bottom of the booth body or the installation surface upward. As a result, the gas is settled, thereby suppressing the amount of reflection of the spray gas on the bottom side of the booth main body, and assisting in preventing the gas from flowing out of the opening which may be caused by the counter pressure.

When the lid provided on the booth body is opened and closed by pedal operation, the pedal can be operated by foot, and the operator can support the object with one hand as needed while holding the object with the other hand. Enables the operation of the spray head with the hand.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a spray booth according to the present invention will be described below in detail with reference to the drawings.

The overall perspective view of a spray booth according to the first actual施例in Figure 1 is shown, A-A sectional view taken along line of FIG. 1 is shown in FIG. In these drawings, the spray booth 10 is configured to include a booth main body 11 in which a predetermined space is formed, and a porous member 12 made of a net or a net disposed in the booth main body 11. .

The booth body 11 is formed in a box shape as a whole by bending appropriate cardboard.
Specifically, as shown in FIG. 2, the bottom wall is formed as an open bottom type, and a pair of side walls 13 located on both left and right sides in FIG. 1
4, a front wall 16 provided between the lower front end of the side wall 13 and having a small vertical height to form an opening 15 on a substantially vertical surface, and a rear wall upper end of the side wall 13 It comprises a top wall 17 and a lid 19 provided on the front edge of the top wall 17 via a hinge 18 on the same plane as the top wall 17. The lower portion of the side wall 13 is a cutout portion 13A which is inclined obliquely upward from the near side to the depth side, whereby a leg portion 20 as a spacer is formed on the depth side.

The top wall 17 has a hanging piece 17A extending downward from a continuous portion of the lid 19, and the interior of the booth main body 11 is partitioned into two front and rear rooms C1 and C2 via the hanging piece 17A. . A slit hole 17B is formed in the base of the hanging piece 17A, and a base piece 19A of the lid 19 is inserted into the slit hole 17B. It is possible.

As shown by a two-dot chain line in FIG. 2, when the lid is opened, the opening 15 is temporarily enlarged so that the object to be coated W on the porous member 12 can be easily set. It has become. The lid 19 has a substantially rectangular hole 21.
And a replaceable first filter 23 fixed to the inner region of the frame 22 by means such as adhesion or engagement. The first filter 23 is formed using a nonwoven fabric or the like as a material. The nonwoven fabric has a fine pore smaller than particles of an adhesive component or the like contained in the gas, while allowing discharge of the spray gas. Things have been adopted. On the both sides in the longitudinal direction of the frame body 22 in FIG. 1, a hanging side wall 24 partially overlapping the side wall 13 is provided, while a hanging front wall 25 is provided from the front end of the frame body 22.

The porous member 12 is supported along a slope of a notch 13A formed at a lower portion of the side wall 13. The porous member 12 is fixed to a relatively flat box-shaped frame 30, as shown in FIGS. The frame 30 is formed of appropriate corrugated cardboard, and has an upper wall portion 31 having a substantially rectangular hole 31A, a peripheral wall portion 32 hanging down from the periphery of the upper wall portion 31, and substantially corresponding to the upper wall portion 31. And a lower wall portion 33 connected to a lower edge of the peripheral wall portion 32 at a position where the peripheral wall portion 32 is located. As shown in FIG. 2, the four piece portions of the upper wall portion 31 are formed into a bent piece portion 36 which is bent to the back side through the cut 35, and the bent piece portion 36 and the upper wall portion 31 are formed. The edge of the porous member 12 is sandwiched between them, so that the porous member 12 is stretched in the hole 31A. In addition, a reinforcing wall portion 38 is provided on the lower wall portion 33, and a second side is provided on the back surface side of the reinforcing wall portion 38 and the lower wall portion 33, that is, on the lower surface side.
Are exchangeably fixed.

Two slit holes 41 are formed in a lower portion of the peripheral wall portion 32 of the frame 30 located on the near side. These slit holes 4
1, a projecting piece 43 formed inside the lower end of the front wall 16 of the booth body 11 is inserted.
As a result, the front side of the frame 30 is engaged with the inside of the front wall 16, while the peripheral wall portion 32 located on the depth side of the frame 30 is engaged in contact with the inner surface of the rear wall 14 of the booth body. The entire frame 30 is inclinedly supported in the booth main body 11 so as not to fall off by the engagement at the front and rear two places.

Next, the operation of the present embodiment will be described.

When the object to be coated W is set on the porous member 12 in the booth main body 11, the lid 19 is opened and the opening 15 is temporarily closed as shown by a two-dot chain line in FIG. It will be performed in a state of wide open. After the setting is completed, when spraying a material such as an adhesive with the spray S,
By closing the lid 19 so as to be positioned on the same plane as the top wall 17 and pressing the spray head of the spray S in this state, the material can be sprayed on the surface of the workpiece W.

When the material is sprayed, the object W is set in an inclined state, so that the gas reflected on the surface of the object W is applied to the room C2 located behind the hanging piece 17A. It tends to fill in. Then, the gas filled here gradually sinks and passes through the inside of the porous member 12 and reaches the second filter 40, where the second filter 40
And is discharged outside. On the other hand, of the spray gas, there is also a gas that fills the room C1 to some extent due to reflection by the object to be coated W, but this gas passes through the first filter 23 and is discharged to the outside. Depending on the spray amount or the spray pressure, a gas flow reflected again by the first filter 23 may be generated. However, this gas flow is pushed back downward by the hanging front wall 25 of the lid 19 and gradually settles down. Then, the light reaches the second filter 40.

When the gas passes through the first and second filters 23 and 40, particles such as adhesive components in the gas are removed from the filter 2.
Each of the filters 2
The particles can be attached to the inner surfaces of the booths 3 and 40, thereby preventing the adhesive components and the like from flying outside the booth main body 11 from scattering.

In a state where the inner surfaces of the first and second filters 23 and 40 are considerably contaminated and the expected filter effect cannot be exerted, new filters 23 and 4 are required.
The number is replaced with 0, and thereafter, a predetermined material application operation can be performed in the same manner.

Therefore, according to such an embodiment, the opening 15 is located on a vertical plane and
The structure is such that the hanging front wall 25 of the lid 19 is located on the upper part of the lid and the material can be sprayed in a state where the lid 19 is continuous with the top wall 17 of the booth main body 11. When gas is discharged through the first filter 23 provided on the body 19, there is an effect that passage of particles such as adhesive components can be prevented as much as possible. For this reason, scattering of the adhesive component and the like can be substantially prevented through the action of releasing only the gas, and the cause of soiling of the floor surface or the like can be effectively avoided. In addition, most of the sprayed gas can be filled in the room C2 behind the hanging piece 16A directed downward from the front edge of the top wall 17, so that gas emission from the opening 15 can be effectively prevented. effective.

When the cover 19 is open, the opening 15
Is temporarily enlarged, so that a large work space for setting the object to be coated W can be secured and workability is improved, while the lid 19 is located on a vertical plane in a closed state. The opening 15 allows only the access of the spray S to contribute to the prevention of scattering of the material.

Further, since the porous member 12 is provided in the lower open area of the booth main body 11 and the second filter 40 is provided on the frame 30 supporting the porous member 12, the outside of the gas which tends to settle out is provided. The release action can be promoted by the filter 40, and at the same time, particles such as adhesive components can be attached to the filter 40. Moreover, since the second filter 40 is configured to be separated upward from the installation surface such as a floor surface by the leg portion 20, a gas discharge space can be physically secured, and the above-described effect can be obtained from this point. It will be possible to support. In addition, since the porous member 12 is disposed in an inclined state, the surface of the object to be coated W has a relative positional relationship that is substantially orthogonal to the direction of spraying by the spray S, and less wasteful material application is expected.

The first and second filters 23,
Since the filters 40 are exchangeably fixed, the use of the booth body 11 and the like can be continued by simply setting a separate filter when the filter effect is lost, and the burden on maintenance costs can be reduced. There is.

Next, other embodiments of the present invention will be described. In the following description of the embodiment, the same reference numerals will be used for components that are substantially the same as or equivalent to those of the first embodiment, and description thereof will be omitted or simplified.

FIG. 4 is an overall configuration diagram of a spray booth according to the second embodiment, and FIG. 5 is a cross-sectional view taken along line BB of FIG. In these figures, a spray booth 10 includes a booth main body 11 having a predetermined space formed therein and a substantially rectangular parallelepiped shape, and four booths as spacers suspended from the bottom side of the booth main body 11. And a leg 50.

As shown in FIGS. 4 and 5, the booth main body 11 has a bottom wall 51 in this embodiment.
Substantially rectangular holes 52 are formed at a plurality of locations on the bottom wall 51, and the second filter 40 is exchangeably fixed so as to close the holes 52. The porous member 12 made of a net or the like is configured to be placed on the bottom wall 51.

The leg portions 50 as spacers are respectively suspended from four corners on the lower outer peripheral side of the booth main body 11 at positions not interfering with the installation region of the second filter 40. The height of the legs 13 is such that the mounting position in the vertical direction can be changed arbitrarily. However, at least the interval between the second filter 40 and an installation surface such as a floor surface at which gas can be released is provided. If there is enough.

As shown in FIG. 6, the porous member 12 is supported by a frame 54 having a hole inside. The frame 54 is formed of an appropriate corrugated cardboard, and a space piece 55 for providing a predetermined interval with the second filter 40 is provided around the frame 54. The other structure is almost the same as that of the first embodiment.

Also in this embodiment, the material can be sprayed on the object to be coated W in the same working manner as in the first embodiment, and the adhesive component and the like can be adhered to the first and second filters 23 and 40. In addition, since the leg portion 50 is configured to be able to adjust the height position of the booth main body 11, an additional effect that the adjustment for performing the spraying operation in a comfortable posture can be obtained.

In the second embodiment, four legs 5
Although the case where the spacer is constituted by 0 has been illustrated and described,
For example, it can be replaced with the spacer 60 shown in FIG. The spacer 60 is formed of relatively hard paper, for example, cardboard, etc., and has a closed-loop frame 61 formed in a substantially rectangular shape when viewed from the top, and a corner 4 on the inner surface side of the frame 61. And an engaging portion 62 formed at the location. This spacer 60
Is provided so as to be foldable at each corner and to be foldable flat as a whole. The engaging portion 62 can be formed by providing notches 63 at two places in the upper and lower portions, while providing a folding line 64 in advance so that the frame 61 portion between the notches 63 can be valley-folded. By expanding three-dimensionally from, it is possible to assemble into the shape shown in FIG.

The spacer 6 assembled in this manner
In a state where the booth main body 11 is inserted and received in the inside of the booth main body 11, the bottom wall 5 of the booth main body 11 is
The four locations around 1 are engaged with each other, whereby a certain gas discharge space is formed between the bottom wall 51 and the installation surface (not shown).

Even if such a spacer 60 is used, the same operation and effect as described above can be obtained, and the height of the booth main body 11 can be increased by facilitating in advance a plurality of types of spacers 60 having different dimensions in the height direction. Position can be adjusted more easily,
It is possible to respond flexibly to the installation environment of the booth body 11. Moreover, because it is foldable,
The effect that handling at the time of unloading becomes extremely easy is added.

FIGS. 8 to 10 show a third embodiment of the present invention. This embodiment is significantly different from the above embodiments in that the opening 15 is provided at a position shifted in a direction inclined with respect to the vertical plane. Specifically, the left edge of the top wall 17 in FIG.
An opening 15 is formed on an inclined line connecting the upper end of the boot 6 and an unillustrated non-coated material can be put in and out of the booth main body 11 through the opening 15.

In the area where the opening 15 is formed, a lid 19 is connected to the top wall 17 via an appropriate hinge structure, and the opening 15 can be opened and closed by the lid 19. . Although the molding material of the booth main body 11 in this embodiment is not limited, when a molded product made of a synthetic resin material is adopted, the hinge structure is formed as a constant thin portion so that the lid 19 can be formed. And the booth body 11 can be integrally formed.

The first filter 23 in the lid 19
Is provided with a work hole 70 at a substantially central portion thereof, and the material can be sprayed through the work hole 70 by spraying.

On the other hand, in the bottom wall 51 of the booth main body 11, a single hole 52 formed in a substantially rectangular shape is formed large, and the same hole 52 as the first filter 23 described above is formed in the hole 52. The second filter 40 is exchangeably fixed and the bottom wall 5
The gas sprayed into the booth main body 11 can be actively released from the first side.

Further, the legs 50 hanging down from the four corners of the booth body 11 are provided longer than the legs 50 in the second embodiment, so that the posture of the application operation by spraying is as simple as possible. It is set to the height of about.

The porous member 12 disposed in the booth main body 11 is used to cover the lid 19 when the lid 19 is closed.
The porous member 12 is disposed so as to be substantially parallel to
A certain interval is provided between the first filter and the second filter 40. Further, the porous member 12 in this embodiment is configured in such a manner that a separate frame used in each of the above-described embodiments is omitted.

Also in the third embodiment, it is possible to close the lid with the object to be coated set on the porous member 12 and spray the adhesive or the like through the working hole 70 by spraying. The adhesion procedure of the adhesive component and the like contained in the sprayed gas is performed in the same manner as described above.

The third embodiment differs from the above embodiments in that the position of the opening 15 is not on the vertical plane, but the working hole 70 as an area for performing the spraying operation.
Is formed in a limited manner, so that the booth body 11
Can be made as close as possible, the scattering of the material accompanying the spraying operation can be almost prevented, and the cause of soiling of the floor surface or the like can be effectively avoided. Further, since the booth main body 11 can be set at a higher position, the spray operation at the time of performing the coating operation can be performed in a more comfortable posture, and the spray booth 10 can be used without using a separate installation table.
It becomes possible to perform the coating operation by itself.

Next, a fourth embodiment of the present invention will be described with reference to FIGS.

The spray booth 10 in this embodiment
Is a booth body 11 formed of a suitable synthetic resin material or metal material, a bag 80 detachably mounted in the booth body 11, and a lid 19 capable of opening and closing the opening 15 of the booth body 11. It is comprised including.

On the bottom wall 81 side of the booth body 11, there is formed a pedal installation space 82 that is recessed inward.
Both sides forming the pedal installation space 82 are formed as a pair of legs 83 as shown in FIG.
The lower end surfaces of the legs 83 are each provided in an open shape, and an elongated plate-like pedal 8 is provided in the pedal installation space 82.
4 is provided horizontally.

The step surface 84 A formed on one end of the pedal 84 is provided at a position slightly protruding outside the side wall 13 of the booth main body 11. On the other hand, the pedal 84
A link bar 85 is provided between the other end of the
Are connected, and a fulcrum 86 is provided on the lower surface in the middle of the pedal 84. Therefore, while the lid can be opened by stepping on the stepping surface 84A of the pedal 84 with a foot, the lid can be closed when the stepping is released.

The bag 80 is entirely formed of a nonwoven fabric having a filter function. As shown in FIG. 13, the bag 80 has an upper end with an opening 91 substantially corresponding to the inner surface shape of the booth body 11. Part 92, a lid forming piece 93 connected to one side edge of the opening 91 and having a flat area substantially corresponding to the opening 91, both side edges of the lid forming piece 93, and an upper end edge of the body part 92. And a folding piece 95 having a pair of bellows structures provided therebetween.

The upper surface of the lid forming piece 93 can be fixed to the inner surface of the lid 19 via an appropriate adhesive or the like, and can be moved in the opening and closing direction together with the lid 19. 11 at a position to close the opening 15 of the folding piece 9.
5 is folded horizontally so that the lid forming piece 93 closes the opening 91 of the body 92.

The porous member 12 is mounted in the bag 80 at a position close to the upper end of the booth main body 11.
As shown in FIG. 14, a plurality of wires 96 are provided on a substantially rectangular frame 95 formed by punching.
Are arranged vertically and horizontally.

When the spray booth 10 in the fourth embodiment is not in use, the lid 19 is closed, and when applying an adhesive or the like, the pedal 84 is depressed to operate the lid. This is performed with the body 19 opened.

Then, with the object to be coated placed on the porous member 12, spraying of an adhesive or the like can be performed in the same manner as described above. After the application is completed, the stepping force on the pedal stepping surface 84A is released, so that the lid 19 closes the opening 15 and, consequently, the opening 91 of the bag 80, so that the gas is completely scattered through the openings 15, 91. Will be prevented.

In the fourth embodiment as well, the legs 83 of the booth main body 11 are open at the lower ends (see FIG. 12), so that there is a gap between the legs 83 and the installation surface where gas can be released. Is formed, so there is no need to form a separate outgassing path.

In a state where the inner surface of the bag 80 is considerably contaminated and the expected filtering effect cannot be exerted, the bag 80 is replaced with a new bag 80, and thereafter, a predetermined material applying operation can be performed in the same manner.

Therefore, according to the fourth embodiment, the opening 91 of the bag 80 can be opened and closed by the lid 19 and the lid forming piece 93 fixed thereto, and this can be opened after the spraying is completed. Since the closed structure is employed, the closed space makes it possible to confine the spray gas inside the bag 80, and the subsequent scattering can be reliably prevented. Further, as a means for opening and closing the opening 91 of the bag 80, the lid 19 attached to the booth body is used, and the lid 19 can be opened and closed by depressing the pedal 84. Opening and closing work of the lid 19 by hand is not required at all.

Since the bag 80 is detachably mounted in the booth main body 11 and covers the entire inner surface of the booth main body 11, the booth main body 11 can be effectively protected from contamination. Continuous use can be performed by replacing only the bag 80, and maintenance cost can be greatly reduced.

The booth body 11 and the lid 19
Since it is constituted by a molded product, it is expected to easily achieve aesthetic matching with the surrounding environment when installed in an office or the like, and it is possible to further expand versatility.

In the fourth embodiment, the booth body 11
Although the configuration in which the lid 19 is provided is adopted, the lid 19 is not necessarily provided when the lid 91 is provided on the bag 80 so that the opening 91 can be opened and closed. On the other hand, when the configuration in which the lid 19 is provided is adopted, the lid forming piece 93 of the bag 80 is omitted since the function of the lid forming piece 93 can be replaced by the lid 19. It is also possible.

Further, in the first to third embodiments, the configuration in which the first filter 23 is provided on the lid 19 is adopted, but this filter 23 may be omitted in some cases. This is because particles such as an adhesive component have a tendency to settle, so that gas can be released through the second filter 40.

Further, in each of the above embodiments, the shape of the booth body 11 is not limited to the structure of the embodiment.
Various geometrical design changes can be made as long as a constant material spray space can be formed inside.

The first and second filters 23, 40
