ABSTRACT:
A plastic drum comprising a side wall, a bottom wall and a top wall having an opening therein and a plastic stem fusion bonded to the inner surface of the base wall in general alignment with the opening such that a dispensing tube can be inserted through the opening with the lower end of the tube engaging the stem to hold the dispensing tube in position adjacent the bottom wall. The plastic drum is made by heating the base of the plastic stem at an elevated temperature and inserting the heated stem into contact with the inner surface of the base of the drum as the hot drum is removed from the plastic forming machine where it has been blown outwardly from a hollow parison in conformity with a mold.
