BACKGROUNDPlastic containers have been used as a replacement for glass or metal containers in the packaging of beverages for several decades. The most common plastic used in making beverage containers today is polyethylene terephthalate (PET). Containers made of PET are transparent, thin walled, and have the ability to maintain their shape by withstanding the force exerted on the walls of the container by their contents. Advantages of PET containers include lighter weight and decreased breakage as compared to glass, and lower costs overall when taking both production and transportation into account. PET resins are also reasonably priced and easy to process. PET containers are generally made by a process that includes the blow-molding of plastic preforms which have been made by injection molding of the PET resin.
Advantages of plastic containers include lighter weight and decreased breakage as compared to glass, and lower costs overall when taking both production and transportation into account. As such, there is a continuous interest in creating the lightest possible plastic container so as to maximize cost savings in both transportation and manufacturing by making and using containers that contain less plastic.
A PET container for storing liquid contents typically includes a base that extends up to a grip portion suitable for affixing a label, as well as providing a location for grasping the container. The grip portion generally transitions into a shoulder, which connects to a bell. The bell has a diameter that generally decreases as the bell extends upward from the shoulder to a neck and a finish portion. The finish portion is adapted to receive a closure, such as a bottle cap, to seal the contents within the interior of the plastic container.
In many instances, the closure includes a tamper evidence band that is disposed around the perimeter of the finish portion. The tamper evidence band generally remains positioned on the finish portion when an end-user loosens the closure to access the contents within the container. As such, the tamper evidence band and the finish portion cooperate to indicate to the end-user whether or not the closure has been previously loosened after being installed by the manufacturer.
One difficulty that may be associated with closures typically installed onto plastic containers is that once the closure is removed from the container, the closure is separable from the container. This may result in the closure being misplaced or lost after being removed from the container, thus hindering resealing unfinished liquid contents within the container. In some instances, misplaced or lost closures may contribute to plastic waste littering the environment. As such, there is a desire to attach or tether closures to plastic containers so as to reduce the environmental impact of misplaced closures while maintaining the convenience and enjoyment often associated with drinking beverages by way of plastic containers. Embodiments disclosed herein provide container closures that include anchors configured to keep the closures coupled with plastic containers after the closures have been unsealed to access contents within the containers.
