Method and apparatus for manufacturing a hollow plastic product

Apparatus for manufacturing a hollow plastic product including at least one tubular section and at least one projecting section which projects outwardly from an outer surface of said tubular section, comprising:

• a first mold half engraved with a first groove including at least one tubular portion corresponding to said tubular section of said product and at least one projecting portion corresponding to said projecting section of said product;
• first supplying means for supplying a parison of first molding material into said tubular grooved portion of said first mold half;
• second supplying means for supplying a clump of second molding material into said projecting grooved portion of said first mold half;
• a second mold half engraved with a second groove, which defines a mold cavity corresponding in outer shape to said product to be manufactured when said second mold half is brought into mating contact with said first mold half;
• means for bringing said second mold half into mating contact with said first mold half after having supplied said parison into said tubular grooved portion and said clump into said projecting grooved portion;
• and
• means for introducing a pressurized gas into said parison while maintaining said first and second mold halves clamped together after said second mold half has been brought into mating contact with said first mold half to carry out blow molding thereby causing said clump to become integrated with said parison.
