Claims

[Claims for Utility Model Registration] (1) A block body 1 made of a flexible material and having a horizontal top surface 5 and a horizontal bottom surface 6 extending parallel thereto; This needle safety capping device for a disposable injection cylinder is provided with one or more vertical holes 4 having a tapered vertical section and extending downward while gradually reducing the diameter of the block body. (2) The device according to claim 1, wherein the vertical hole 4 has a spiral strip formed on the inner wall surface of the vertically tapered cross section. (3) In the device according to claim 1 or 2, the vertical hole 4 has a large diameter opening 2 provided on the horizontal top surface 5 and a small diameter opening 3 provided on the horizontal bottom surface 6, and both openings 2 and 3 are arranged vertically. The above-mentioned device comprises a through hole 4 having a tapered cross section and communicating with each other. (4) In the device according to claim 1 or 2, the vertical hole 4' is a non-through hole with a tapered longitudinal section extending vertically downward while gradually decreasing in diameter from the large diameter opening 2' provided in the horizontal top surface 5. The above device consisting of: (5) In the device according to claim 1 or 2, the block body 1 has a horizontal top surface 5 having a small area.
and a horizontal bottom surface 6 having a larger area, each of the surfaces 5 and 6 forming a similar polygonal, circular or elliptical shape. (6) A device according to any one of claims 1, 2 or 3, wherein the block body is constructed of a non-flexible material and has one or more cylindrical vertical through-holes to provide a flexible structure.
