Abstract

A sealing stopper or piston for a syringe and a prefilled syringe using the same, provided with a backstop function, can be provided without increasing the production cost, which comprises a skirt part capable of serving as a backstop device.

Claims (4)

1. A piston for a syringe for sealing an injection barrel filled with a medicament comprising a skirt part capable of serving as a backstop device.
2. The piston for a syringe as claimed in claim 1, wherein the piston is subjected to film lamination and/or lubricant coating, the skirt part has a rubber exposed surface on a contact surface with the injection barrel and at least a part of the rubber exposed surface is inside the maximum outer diameter of the stopper and outside the inner diameter of the injection barrel.
3. The piston for a syringe as claimed in claim 1 or 2, wherein an angle of the skirt part is in a range of 30 to 80 ° based on a standard surface vertical to such a direction that the piston is slidably moved in the injection barrel.
4. A prefilled syringe comprising an injection barrel filled with a medicament and sealed by a piston, the piston is the piston for a syringe as claimed in any one of claims 1 to 3.
