There is disclosed a feeding teat for use on a drinking receptacle. The teat has an outlet member having an outlet through which fluid from the receptacle is delivered under pressure supplied by a user of the receptacle and a collar portion that attaches to an opening of the receptacle. The under surface of the collar portion abuts with the upper surface of the opening of the receptacle to form a substantially sealed engagement between the outlet member and the receptacle. Either the under surface of the collar portion or the upper surface of the opening has at least one vent configured such that when pressure is applied to the outlet member the vent member permits controlled ingress of air into the container to facilitate flow of fluid from the outlet and when the pressure is removed the vent prevents ingress of air into the container to facilitate a controlled vacuum pressure with the container.
