Container with inliner bag and one-way dispenser valve

Abstract

An inliner bag having a plastic bag produced by injection blow molding and having a delivery nozzle, and in the shape of a bottle, preferably of a low-density polyethylene (LDPE). The bottle has in the shoulder region of the delivery nozzle or in the lower region thereof, an external radially projecting rim which is intended to act as a disc valve against the inside of the outer container. The one-way valve has a plug fitting into the delivery nozzle and has a delivery channel with a conically widening mouth. A cannula having a tension spring and a cone valve which are integral with it fits into the delivery channel. The cone valve cooperates with the widening mouth. The inliner bottle is squeezed prior to filling and is pushed through the bottle nozzle into the outer bottle and is then filled and the plug with the already inserted one-way valve is then inserted.
