PURPOSE:To permit a vertical slit of a synthetic resin-made cap to be accurately formed in a gap between the locking tongue pieces formed on the cap with an interrupted continuity in space between each of them. CONSTITUTION:Locking tongue pieces 4 are provided at equal spaces and the upper part of a cap is formed into the exterior contours of an equilateral polygonal column having the sides in the same number as the locking tongue piece 4 or the divisor obtained therebetween. A plurality of horizontal slits 6 are formed with an interrupted continuity in space between each of them and a vertica slit 8 is formed extending near the one end of a horizontal slit 6 and through a gap 15 between the locking tongue pieces 4. |
