A cap on a bottle is selectively opened to permit passage of liquid to and from the chamber and closed to prevent passage of liquid. The cap has a collar that threads onto the bottle's mouth and a shroud that moves relative to the collar by applying a longitudinal force to the shroud's shoulder. By applying the force, the shroud moves longitudinally toward the bottle. In some embodiments, a valve is thereby rotated to unblock a throat so that liquid may pass from the opening defined by the shoulder to the chamber in the receptacle. In other embodiments, a dome is thereby displaced longitudinally to unblock the throat so that liquid may pass through.

A bottle that is easy to carry and clean includes a bottle body and a bottle cap. The bottle body includes an upper section and a lower section. The lower section has a lower chamber therein and an opening at a top end thereof. The upper section has an upper chamber therein and a bottle mouth at a top end thereof. The upper section is detachably coupled to the lower section through a coupling portion and closes the opening. The upper chamber communicates with the lower chamber. The bottle body has a flat configuration with a width greater than twice a thickness after the upper section and the lower section are combined together. The bottle cap is configured to cover the bottle mouth.

A sealing closure for dispensing fluid includes a closure body. The closure body has an attachment portion configured to attach to a container containing fluid, a dispensing portion, and a conduit connecting the attachment portion and dispensing portion and configured to direct fluid from the attachment portion to the dispensing portion. The sealing closure further includes a spring lid attached to the dispensing portion. The spring lid has a first portion coupled to the closure body, a second portion not attached to the closure body. The second portion is configured to contact the closure body when a pressure of the fluid is below a threshold, and flex to separate from the closure body when the pressure of the fluid meets or exceeds the threshold to create an opening for dispensing the fluid.

In a container spout portion included in a container body and configured to be sealed as a seal portion comes into contact with an inner circumferential face in association of attachment thereto of a cap having the seal portion therein, an arcuate portion convex inwards is formed between a top face and the inner circumferential face of the container spout portion. A tangential line to the arcuate portion starts from either a joining point between the arcuate portion and the top face or from a crossing point between a virtual extension line of the arcuate portion and the top face or a virtual extension line of the top face. An angle θ formed between the top face and the tangential line ranges from 30 to 60 degrees.

Disclosed are devices, systems and methods for controlling scent delivery by a scented article for beverage containers such as box cartons. In some aspects, a scent delivery system includes a cap removably attachable to a carton container at an opening of the carton container, the cap being moveable between an open position that allows a fluid beverage within the carton container to flow outward and a closed position that prevents the beverage to flow outward; and a scented article that couples to the carton container or the cap and operable to generate a scent capable of stimulating an olfactory sensation of a user including during consumption of the beverage when the cap is in the open position, and when the cap is in closed position, a seal is created by the cap and a base region of the carton container to enclose the scented article and lock in the scent.

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 package is disclosed that includes a container and a closure. The container includes a container neck finish having a radially inner surface, a radially outer surface, and an axial outward end surface extending between the radially inner and outer surfaces. The radially outer surface includes a straight cylindrical upper portion and a threaded cylindrical lower portion. The closure includes a base wall engaging the axial outward end surface of the container neck finish, an external skirt extending away from the base wall and having a threaded section with internal threads engaging the container neck finish, and a pleated section between the threaded section and the base wall.

The combination lock for a liquid bottle is a container. The combination lock for a liquid bottle is configured for use in storing a liquid. The combination lock for a liquid bottle is a secured device. By secured device is meant that the structure of the combination lock for a liquid bottle is formed with a lock that prevents unauthorized entry into the combination lock for a liquid bottle. The combination lock for a liquid bottle comprises a bottle, a bottle cap, and a permutation lock structure. The permutation lock structure mounts in the bottle cap. The bottle cap attaches to the bottle. The bottle cap forms a fluid impermeable seal that encloses the liquid in the bottle. The permutation lock structure fixes the bottle cap in the closed position.

The disclosure describes a zipper including two rows of zipper teeth, in which at least some of the zipper teeth include a negative Poisson's ratio (NPR) foam material having a Poisson's ratio of between 0 and −1, and a slider movably attached to one of the rows of the zipper teeth and configured to connect the two rows of zipper teeth when the slider is moved in a first direction and to disconnect the two rows of zipper teeth when the slider is moved in an opposite direction.

A cap for making a soft drink in a threaded bottle includes an inner cap, an outer cap and a flavor container. The inner cap has external threads and internal threads that match the threads of the mouth of the bottle, and the outer cap has internal threads that match the external threads of the inner cap. The cap includes a first releaser for opening the flavor container into the bottle when the cap is being screwed onto the mouth of the bottle. The cap further includes a carbon dioxide container and a second releaser for opening the carbon dioxide container into the bottle when the outer cap and the inner cap are being screwed relative to each other. The disclosed embodiments also relate to a method for making a soft drink.
