BACKGROUND
The present disclosure relates to a container closure, and particularly to a closure for mounting on the top of a bottle or other container. More particularly, the present disclosure relates to a closure and pour spout associated with a bottle or container finish or neck.
SUMMARY
According to the present disclosure, a package includes a container and a closure cap for mounting on the container. The closure cap is coupled to a neck of the container to block selectively removal of product stored in the container. A product measuring cup included in the closure cap covers a discharged tube coupled to the container when the closure cap is mounted on the container.
In illustrative embodiments, the closure cap includes the product measuring cup and a spout sealer for forming a seal with the neck of the container. A pour-spout insert is coupled to the container and includes the discharge tube and a product-drainback aperture. The closure cap is formed to define a residual-product catch basin to collect excess product remaining on an exterior surface of the product measuring cup after a user discharges product from the container into the product measuring cup. The closure cap seals against the container and directs the excess product held in the product measuring cup and residual-product catch basin toward the product-drainback aperture to re-enter the container and minimize waste of the product.
In illustrative embodiments, the package further includes a child-resistant lock. The child-resistant lock includes a lock tab coupled to the closure cap and a companion stationary tab blocker coupled to the container. The tab blocker engages with the lock tab to block rotation of the closure cap relative to the container to block removal of the closure cap. An adult user engages an annular outer sidewall of the closure cap to move the lock tab relative to the tab blocker to remove the lock tab from engagement with the tab blocker and allow removal of the closure cap from the container.
In illustrative embodiments, the closure cap rotates relative to the container about an axis during mounting and dismounting of the closure cap. The spout sealer includes a rim sealer and a plug wall. The rim sealer seals against a rim of the neck of the container and the plug wall seals against an interior of the neck when the closure cap is mounted on the container. In a first angular position of the closure cap, the plug wall and rim seal are both engaged with the neck to seal an opening of the container. In a second angular position of the closure cap, the plug wall is engaged with the neck to seal the opening and the rim sealer is spaced apart from the neck.
In illustrative embodiments, a tamper-evident band is coupled to the closure cap through a frangible connection. The tamper-evident band engages with the container to block or limit rotation of the closure cap while the tamper-evident band is coupled to the closure cap. A user removes the tamper-evident band along the frangible connection to allow the closure cap to dismount from the container.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
