An apparatus for providing a ball point pen having an elongated ink reservoir terminating at one end in writing means and at an opposite end in an opening, said ink being present in said reservoir to a level below its open end to define at first chamber adapted for closure by a closure member, said apparatus comprising a base member, formed with a recess at one end thereof, an elastic member within said recess of said base member and pOsitioned in relation to a recess terminating wall of the base member to define therewith a second chamber, said elastic member having an axial through passage leading to and communicating with said second chamber, said axial passage receiving the opposite end portion of said ball point pen with its open ended reservoir within said second chamber thereby affording communication between said first chamber and said second chamber, and ultrasonic vibration generating means having an elongate member extending through that end thereof opposite said one end into said second chamber in axial alignment with said open ended reservoir for transmitting ultrasonic oscillations to the end closure initially loosely fitted into the open end of the reservoir, and a fluid passage provided in the base member leading into said second chamber for supplying a high pressure fluid within said second chamber accessible to the chamber first in said reservoir before closure by ultrasonic generating means of said closure means, whereby to seal said closure member to said open end with a pressure in the first chamber equal to the pressure in the second chamber, and means for supplying said high pressure fluid.
