Compule and syringe tip having discharge nozzle diameter widened at tip

Abstract

To provide a compule or syringe tip that can discharge viscous material in an intended shape by reducing deformation of the viscous material during discharge, can prevent viscous material from adhering to unintended portion by reducing an amount of viscous material that adheres to a nozzle tip, and can reduce dripping of viscous material to improve the anti-dripping property of the viscous material. To provide a compule or syringe tip having a discharge structure for discharging viscous material from a discharge opening, wherein the discharge structure comprises a flow path that is formed around a virtual central line and allows the viscous material to move, and a tapered flow path formed between the flow path and the discharge opening, wherein a cross-sectional area of the tapered flow path gradually increases toward the discharge opening.
