Abstract

Claims (12)

1. A process for closing a fill passageway into a container, the process comprising the steps of

providing a container having an interior region and a neck finish coupled to the container and formed to include a wide-mouth opening providing a fill passageway communicating with the interior region of the container,

coupling a closure cap to a pour spout formed to include a fluid-discharge outlet to establish a preassembled closure unit wherein the closure cap covers the fluid-discharge outlet of the pour spout,

discharging a fluid material through the wide-mouth opening of the neck finish into the interior region of the container,

mounting the preassembled closure unit to the neck finish, and

anchoring the pour spout in a stationary anchored position on the neck finish so that the pour spout will remain in its stationary anchored position and is blocked by a lug from rotating clockwise and from rotating counterclockwise but without blocking later removal of the closure cap from the pour spout by a consumer to expose the fluid-discharge outlet of the pour spout to permit discharge of fluid material from the interior region of the container through the exposed fluid-discharge outlet while the pour spout remains in the stationary anchored position on the neck finish.

2. The process of claim 1 , wherein in the step of anchoring the pour spout comprises

providing an anchor rib on one of the pour spout and neck finish to be located between lugs on the other of the pour spout and neck finish to anchor the pour spout in the stationary anchored position on the neck finish whereby rotation in clockwise and counterclockwise directions is opposed.

3. The process of claim 1 , wherein the coupling step further comprises the step of

providing a pour spout including a discharge tube formed to include the fluid-discharge outlet and a fluid-admission inlet opening into the interior region of the container when the pour spout is anchored to the neck finish, a rim, and a product-drainback cup coupled to the discharge tube and to the rim and formed to include a product-drainback reservoir.

4. The process of claim 1 , wherein the coupling step further comprises

providing a pour spout including a product-drainback cup and a discharge tube coupled to the product-drainback cup to form a product-drainback reservoir therebetween formed to include the fluid-discharge outlet and a fluid-admission inlet opening into the interior region of the container when the pour spout is anchored to the neck finish.
