Abstract: A closure element for a beverage container is in the form of a sports cap, other closer, or initially closed straw, and provides a chamber for containing colorants in the form of liquids, gels, granules, powders, tablets or other solid bodies. Closures such as valves, rupturable membranes, hinged doors, clamps or undersized holes provide closer structure for initially keeping the chambers closed with respect to the colorant so that colorant does not flow into the beverage until released to do so by the customer. Upon opening ends of the chambers, colorants flow into beverages in the containers, which containers are made of see-through/clear or partially see-through materials. In a preferred embodiment, the colorant is a material enclosed in at least one capsule which flows through openings in the chamber within the closure element when the capsule is ruptured or perforated.

Abstract: A closure element for a beverage container is in the form of a sports cap, or other closer, or initially closed straw and provides a chamber or reservoir for containing colorant in the form of liquids, gels, granules, powders, tablets or other solid bodies. Closures such as valves, rupturable membranes, hinged doors or clamps provide closer structure for initially keeping the chambers closed. Upon opening the bottom ends of the chambers, colorants flow into beverages in the containers which are see-through/clear or partially see-through/clear. Coloration of the beverage is voluntarily initiated by the consumer and the thus colored beverages are then consumed by passage through the closure element. In one embodiment of the invention, the colorant is a medicinal agent which can be colored or may be clear. The medicinal agent is released into liquid, which may be water, for ingestion by a patient.

Abstract: A container having a rotatable dispenser closure is disclosed. The container has a body portion and a closure portion. The container body has at its upper end a closure securing section that is folded inwardly and downwardly so that it is in contact with the inner surface of the body sidewall. The closure includes a sidewall having a lower section, an upper section and a first rim. The lower section of the closure sidewall fits snugly against the interior of the body sidewall below the closure securing section, the upper section of the closure sidewall engages the closure securing section, and the first rim of the closure sidewall rests on the top of the closure securing section. In this manner, the closure is coupled to the container body so that the closure is prevented from upward or downward movement but not axial rotation. Both the body sidewall and the closure sidewall contain apertures that are positioned so that they may be aligned when the closure is rotated.

Abstract: A container has a lid connected to a spout. The lid has an inner door which allows communication between the container and the spout. The spout has an outer door. To remove material from the container, one opens the inner door, while maintaining the outer door closed, and transfers material from the container to the spout. One then closes the inner door, and then opens the outer door, allowing material to exit the spout. At all times, material in the container is sealed from the outside by at least one of the inner door and the outer door. The invention helps to maintain the freshness of the material in the container, by virtually eliminating direct contact between such material and the outside environment.

Abstract: A fire fighting system uses a bucket suspended from a helicopter to deposit fire retardant onto a fire from an opening in the bottom of the bucket. The bucket has a predetermined configuration and a valve for controlling the area of an opening through which the retardant is deposited when the bucket is suspended from the helicopter. A suitable mechanism, such as an electrically driven valve actuator, varies the area of the opening to deposit the retardant at a volume flow rate as a desired function of time while the helicopter flies along a drop line. The mechanism varies the area of the opening in accordance with a schedule determined before discharge is begun according to the configuration of the bucket, the flow characteristics of the opening as the valve changes the area thereof, and the initial amount of the retardant material in the bucket.
