Abstract

A new masking member of a vessel type comprising a bottom, (a) wall(s) which extend(s) upwards from the perimeter of said bottom, a flange which is extended from the upper edge(s) of said wall(s), and an adhesive layer formed on the surface of said flange, with said masking member made of a thermoplastic foam, is presented in this invention. When said masking member is used, said masking member is attached by said adhesive layer to a part of the surface of an article which is necessary to be protected from a surface treatment. After said surface treatment, said masking member may be removed from said part of said article by heating and softening or by a hook.

Claims

1. A thermoplastic foam vessel shape masking member comprising a bottom, a wall extending upwardly from the perimeter of said bottom, a flange extending outwardly from the upper edge of said wall and an adhesive layer formed on the upper surface of said flange.

2. A masking member of claim 1, wherein said masking member is made of polystyrene foam.

3. A masking member of claim 1, wherein said masking member is produced by vacuum forming from a sheet of a thermoplastic foam.

4. A masking member of claim 1, wherein said masking member is produced by vacuum forming from a polystyrene paper.

5. A masking member of claim 1, wherein said adhesive layer is covered with a release sheet.

6. A masking member in accordance with claim 1 wherein a grip is provided extending from the outside of said bottom.

7. masking member in accordance with claim 1 wherein said wall extending upwardly from the perimeter of said bottom is an inner wall and wherein an outer wall is provided extending downwardly from the perimeter of said flange.

8. A masking member of claim 7, wherein a projection grip is provided outwardly from the outside said bottom.

9. A masking member of claim 7, wherein said masking member is made of polystyrene foam.

10. A masking member of claim 7, wherein said masking member is produced by vacuum forming from a sheet of a thermoplastic foam.

11. A masking member of claim 7, wherein said masking member is produced by vacuum forming from polystyrene paper.

12. A masking member of claim 7, wherein said adhesive layer is covered with a release sheet.

13. A masking member in accordance with claim 1 wherein said wall which extends upwardly from the perimeter of said bottom is an inner wall, wherein said flange which extends from the upper edge of said inner wall is an upper flange, wherein an outer wall extends downwardly from the perimeter of said upper flange and wherein a lower flange extends from the lower edge of said outer wall.

14. A masking member of claim 13, wherein said masking member is made of polystyrene foam.

15. A masking member of claim 13, wherein said masking member is produced by vacuum forming from a sheet of a thermoplastic foam.

16. A masking member of claim 13, wherein said masking member is produced by vacuum forming from a polystyrene paper.

17. A masking member of claim 13, wherein said adhesive layer is covered with a release sheet.

18. A masking member in accordance with claim 1 wherein said wall which extends upwardly from the perimeter of said bottom is an inner wall, wherein said flange which extends outwardly from the upper edge of said inner wall is an upper flange, wherein a middle wall extends downwardly from the perimeter of said upper flange, wherein a lower flange extends outwardly from the lower edge of said middle wall and wherein an outer wall extends upwardly from said lower flange.

19. A masking member of claim 18, wherein said masking member is made of polystyrene foam.

20. A masking member of claim 18, wherein said masking member is produced by vacuum forming said a sheet of a thermoplastic foam.

21. A masking member of claim 18, wherein said masking member is produced by vacuum forming from a polystyrene paper.

22. A masking member of claim 18, wherein said adhesive layer is covered with a release sheet.
