Abstract
A product includes a container including a neck, and a fitment having a portion coupled to the neck of the container via an interference fit.
Claims6
A method of producing a product that includes:
- (a) flowing liquid into a glass container having a neck with a cylindrical interior surface;
- and then
- (b) coupling a fitment into the neck of the container via an interference fit between a circumferentially continuous cylindrical exterior surface of a metal outer wall of the fitment and the corresponding cylindrical interior surface of the container, that non-removably secures the fitment to the container to render the product tamper-evident and wherein the fitment is an anti-refill fitment including an anti-refill valve carried within the metal outer wall of the fitment and is at least partially composed of plastic,
- wherein the coupling step (b) includes providing the container neck at a first temperature, providing the metal outer wall at a second temperature less than the first temperature, and then inserting the metal outer wall into the container neck and the coupling step (b) also includes inserting the fitment into the neck of the container until the fitment abuts an internal shoulder within the container so that an end of the fitment extends from the neck of the container to form an anti-drip edge.

A method of inserting a fitment into the neck of a container, which includes the steps of:
- (a) providing a glass container having a neck at a first temperature and a cylindrical interior surface,
- (b) providing a metal ring having a circumferentially continuous cylindrical exterior surface corresponding to the cylindrical interior surface of the container neck, wherein the metal ring is at a second temperature less than said first temperature, wherein said ring has an axial length such that an end of said ring extends from the neck of the container to form an anti-drip edge, wherein an anti-refill valve is carried within said ring and includes a check valve at least partially composed of plastic,
- (c) inserting said ring into the neck of the container until said ring abuts an internal shoulder within said container, and
- (e) allowing temperatures of the container neck and the ring to equalize to secure said ring within said neck.
