Tamper-evident anti-refill dispensing fitment for a container

摘要

An anti-refill product includes a container including a neck with a neck finish, a fitment received in the neck, and a radially expandable element detachably coupled to the fitment. The radially expandable element is disposed to engage a detent in the neck and detach from the fitment when the fitment is removed from the neck, such that the radially expandable element falls into the body and expands, preventing removal into and through the neck.

主权项

1. An anti-refill product that includes:
a container including a base, a body extending in a direction axially away from the base, a shoulder extending in a direction axially away from the body, and a neck extending in a direction axially away from the shoulder and including a neck finish and an interior surface, and a detent; and an anti-refill dispensing fitment positioned in the neck of the container, and including a detachable portion having a radially expandable element that is radially compressed when disposed in the container neck and a detent engagement element to engage the container detent, wherein, if the fitment is displaced in an axial direction away from the container base, then the detent engagement element engages the detent such that continued displacement of the fitment away from the base results in detachment of the detachable portion such that the detachable portion falls into the container body and the radially expandable element expands and thereby renders the product tamper-evident.
