Abstract

806,296. Reservoir pens. PENKALA PRODUCTS, Ltd. June 18, 1957 [Aug. 16, 1956], No. 25085/56. Class 146(3) In a retractable ball-point pen, the writing unit 10 is retracted within the barrel 17 by rotating a cap portion 19 which has a screw-thread connection 22 with the barrel. As shown, the reservoir 11 of the writing unit has press-fitted therein the reduced shank of a peg 13, 16 which has screw-thread connection with an adaptor 21 press-fitted into the rear end of the cap 19. The writing unit can thus be withdrawn from the barrel by rotating the peg 13, 16 in relation to the cap 19. The rear portion of the barrel 17 is recessed to provide two shoulders 24, 25 which co-operate with a shoulder 26 on the cap 19 to limit the movement of the barrel in relation to the writing unit 10. The rear end of the barrel 17 is slotted so that it may yield to permit the passage of the shoulder 26 over the rear shoulder 25 on the barrel during assembly. The barrel and the reservoir may be of synthetic plastic material, and the major portion of the barrel may be of hexagonal or octagonal cross-section. The cap 19 and adaptor can be made in one piece. Specification 788,257 is referred to.
