A soft top insert, comprising:
- a spout comprising:
- a lower end having a first external circumference;
- a top portion having a second external circumference;
- and
- a middle portion having an external circumference that is smaller than the first external circumference of the lower end and the second external circumference of the top portion,
- wherein at least the middle portion is composed of a first material having a first durometer to prevent the spout from being torn from the bite of a child user;
- and
- a base of a lid which is adapted to be sealingly attachable to a container, and comprising an upper end, a lower base end, a ventilation shaft on the upper end, wherein the base and spout lower end comprise a second material that connects with the first material in the middle portion of the spout, and which second material has a second durometer less than the first durometer of the first material,
- wherein the middle portion of the spout is a separate structure than and is attached to the lower end of the spout at a point of attachment, wherein the point of attachment forms a circumferential external bump which projects outwardly from an external surface of the middle portion, and further forms a circular internal channel.
