<p>PROBLEM TO BE SOLVED: To reduce the volume of a removel head and the quantity of a resin material required therefor, reduce the bulk of a bottle at the time of transport and reduce transport cost by providing a plurality of holes for blowing and discharging air therethrough at the time of blow molding in the removal head, which is to be removed before the bottle is packed with contents, and arranging these holes in a direction intersecting with the direction of height of the bottle. SOLUTION: Air holes 13, 14 and closure parts 13a, 14a therefor, which are used at the time of blow molding, are arranged in a direction intersecting with the direction of height of a bottle, further preferably, in a direction orthogonal thereto. Accordingly, both the air holes 13, 14 can be made at a sufficient distance between them in face A. Further, the height of the face A can be made small, and therefore, the height H2 of a removal head 11a can be made remarkably small. It is also possible that the height of the plane A is made shorter until it is remarkably approximated to the diameter of the closure part 14a of the large diameter air hole 14. Accordingly, when the removal head 11a is removed on a cutting plane line L, a resin quantity which becomes wasteful can be minimized, and the bulk of the removal head 11a can be much reduced at the time of packaging.</p> |
