Abstract
A container (10) has a valve (20) to control flow of liquid out of the container (10). The valve (20) has an inline check valve (30) positioned in the inlet section (22) of the valve (20). The inlet section (22) of the valve (20) is in turn positioned in the discharge port (13) of the container (10), thereby positioning the check valve (30) on the inlet side of the valve (20) and in the container (10) so as to be tamper-resistant.
