ABSTRACT OF THE DISCLOSURE
Blow molded plastic articles such as solvent containers
for use in motor vehicles are often equipped with lugs for
mounting the articles in the vehicles. In order to avoid problems
when removing the articles from the mold, the usual practice is
to mold the lugs separately, incorporate the lugs into the mold
prior to blow molding, and to blow mold the articles with the
lugs on the parting line of the mold, i.e. the line where the
mold halves meet to define the mold cavity. This limits the
design of the blow molded articles, and severely slows down
production, since each molding cycle must be interrupted to insert
the lugs. A solution to the problem is to blow mold the articles
with grooves for receiving separately molded mounting lugs. Thus,
there is no need to reduce production speed, and the grooves
can be provided at locations other than the parting line.
