An improved snap-on/twist off closure which is very durable. The invention is also directed to a package comprising the closure, e.g., a bottle in combination with the closure. The closure includes an upper wall defining an opening and a cylindrical snap on pipe depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess and a guidance recess. The resistance recess and the guidance recess accommodate a forcing element on a shoulder of the bottle and permit unscrewing of the closure.

A cap assembly for closing an opening in a vessel may include a stopper and a rigid cap adapted to fit over the stopper and onto a vessel. The stopper may include a polymer body adapted to fit an opening of the vessel and a tubular portion defining an internal passageway extending through the polymer body. The rigid cap may include a pressure based locking mechanism adapted to engage the vessel under a unidirectional force and a tamper evident feature.

A product dispenser with a reservoir for a product and a cap. The cap has a first assembly and a second assembly. The first assembly can include a button configured to dispense the product through a lower end orifice of the pipette, when the button is actuated. The second assembly can include a pipette rigidly connected and in fluidic communication with a chamber configured to change its volume depending on the movement of the first assembly relative to the second assembly and the movement of the button.

Convenience of an ink bottle and a bottle set is improved. An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.

A cap for a container with a hinged lid includes a first part and a second part that are snap-associated. The first part has a lower cylindrical portion and an upper cylindrical portion, and the second part includes a covering lid having an annular portion and a lid portion and a hinge arrangement therebetween, which includes a strip arranged in a window opening formed in the side surface of the lid portion and open towards the annular portion. The strip has weakened foldable end areas connected to the annular and lid portions, and a folding invitation line that divides the strip into two portions with a central recess therebetween. Folding invitation lines are also provided between the two portions of the strip and an end edge of the opening in the lid portion.
