Document Type and Number:
Japanese Patent JP2007516822
Kind Code:
A
Abstract:
Syringe for dispensing foam having a syringe barrel, a nozzle and a bore to receive a syringe plunger having a front end and a back end. The syringe plunger includes at the front end thereof a waste container defined by a cylindrical side wall, a front end wall and a rear end wall, the walls being arranged such that an external cylindrical surface of the walls forms a seal with an internal surface of the syringe barrel. The waste container has an inlet aperture in the front end wall which is in communication with the syringe nozzle when the plunger is fully depressed into the syringe barrel. The waste container further has a hydrophobic vent in the rear end wall thereof which allows air to escape from the waste container while substantially preventing foam from escaping the waste container when the syringe is in use.
