Description
~ 3 A MASKING STRUCTURE
BACKGROUND OF THE INVENTION
The present invention relates to a masking structure to protect a hole of an article from a surface treatment.
More particularly, the present invention relates to a masking structure comprising a hole of an article which is surrounded by a boss and a masking member consisting of a plate having a groove in its circumference, wherein said masking member is attached onto said hole by inserting said boss surrounding said hole into said groove of said masking member.
When a surface treatment is effected on the surface of an artic]e, and if said surface of said article has a hole in which said surface treatment should not be effected, said hole will be protected by said masking member;
DESCRIPTION OF THE PRIOR ART
Hitherto, as shown in FIG. :3, a masking member ~103) consisting a vessel type inserting part (103)A and a flange (103)B extending from the upper eclge of said inserting part (103)A has been provided to protect a hole (102) of an article (101) (USSN No. 101~89).
Said masking member (103) is attached onto said hole (102) by inserting onto a boss (102)A surrounding said hole (102). In the case that said surface treatment has a heating process and said masking member (103) is made of a thermo-plastic material, said masking mem~er t103) may contract by said heating since said masking member has residual strain when said masking member is molded and falls into said hole ~102) as sho~n in FIG. 4. As a result, said 7 ~q ~ ~ ~
hole (102) cannot be completely protected by said masking membex (103) through said surface treatment process.
S~ A~ U~ V~U-`101~
Accordingly, an object of the present invention is to completely protect a hole of an article from a surface treatment.
Another object of the present invention is to prevent the contraction of a masking member attached onto ~said hole of said article.
According to the present invention, there is provided a masking structure comprising a hole of an article which is surrounded by a boss and a masking member consisting o a plate having a groove in its circumference, wherein said masking member is attached onto said hole by inserting said boss surrounding said hole into said groove of said masking member.

FIGo 3 is a partial side sectional view showing a hole of an article protected by a masking member.
FIG. 4 is a partial side sectional view showing that said masking member contracts by heating and falls into said hole.
DETAILED DESCRIPTION
Referring now to FIG. 1 and FIG. 2, a hole (112) of an article (111) is surrounded by a boss (112)A. A plate type masking member consists of a vessel type inserting part (113)A, a groove (113)B surrounding said inserting part (113)A, and a flange (113)C extending from the outside of said groove (113)B.
Said masking member (113) may be produced by the vacuum forming or press molding of a plastic sheet such as a polystyrene sheet, polyethylene sheet, polypropylene sheet, polyurethane sheet, and the like, a foamed plastic sheet such as a foamed polystyrene sheet, foamed polyethylene sheet, foamed polypropylena sheet, foamed polyurethane sheet, and the like, a laminated sheet consisting of a plural number of sheets selected from said plastic sheets and foamed plastic sheets. Further, said masking memb~r (113) may be produced by expansion molding using expandable beads such as expandable polystyrene .beads, expandable polyethylene beads, e~pandable polypropylene beads~ and the like or by injection molding using plastic pellets such as polystyrene pellets, polyethylene pellets, polypropylene pellets and the like.
An inorganic filler such as calcium carbonate, talc, bentonite, fly ash, blast furnace slag and the like may be mixed in said plastics as a material of said masking member (113~. When said inorganic filler is.mixed in said plastics, the mechanical strength of said masking member (113) may `
' ' ', ,. : ` , ~ :
::
be improved and the plastic as the material of said masking member t113) may be saved. Further when said masking member (113) is incinerated after use, the heat of combustion from said burnt masking member may be reduced since said inorganic filler in said masking member is incombustible. Therefore, the life of the incinerator may be prolonged.
. . .
Preferabla plastic as the material for the masking member (113) may be a polyolefin such as polyethylene, polypropylene and the like since said polyolefin has solvent resistance.
Said masking member (113) is attached onto said hole (112) by inserting said boss (112)A of said hole (112) into said groove (113)B of said masking member ~113) berore a surface treatment.
When said masking member (113) is heated and softened during said surface treatment, a contraction stress originating in the residual strain is generated in said masking member (113) but the contraction of said masking member (113) is prevented since said groove (113)B of said masking member(113) firmly holds sa:id boss (112)A. Said boss (112)A may be firmly caught bet~een the pair of walls (113~D, (113)D of said groove (113)B since the contraction force is generated in said groove (113)B. Accordingly, said mas~ing membe~ (113~ is prevented from contracting by heating and so does not fall into said hole (112).
