Abstract: The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment includes a flexible valve extending across the channel. The flexible valve includes a slit which opens to permit flow therethrough. The flexible valve includes an ethylene/?-olefin multi-block copolymer.

Abstract: A method for processing a multidimensional array object in which a multidimensional array is implemented by an array of array objects. The multidimensional array object comprises array objects which constitute the multidimensional array. Flags representing that it is possible to optimize a process for elements of the multidimensional array object are added as additional information. The flags are stored in a storage device (main memory for instance). Then, a machine code corresponding to a state of the flags is executed.

Abstract: A dispensing structure, and a package with a dispensing structure, is provided with a valve. In one embodiment, the dispensing structure is a multi-piece fitment. The multi-piece fitment includes a base for mounting to the container and a valve carrier for mounting to the base. A flexible, self-sealing slit-type valve is mounted within the carrier. In another embodiment, a fitment is mounted in the opening of a thin-walled, flexible, collapsible container, and the flexible valve is mounted in the fitment. In yet another embodiment, a package includes a container having a corner wall defining an opening, and a fitment is sealingly mounted to the corner wall at the opening. A valve is disposed within the fitment. A removable and disposable cover extends from the container over the fitment and at least a portion of the corner wall to define a hermetically sealed volume around the fitment. The cover may be pulled away from the container to expose the fitment.
