A closure for a container. The closure includes a carbon dioxide emitter, and a release rate control layer that is configured to control release of carbon dioxide from the carbon dioxide emitter into the container when the closure is coupled to the container.

A portable bubble water bottle includes a shell, a separation tank, a bottom cover, and a gas supply device. A liquid storage space and a gas supply space are individually defined on the upper and the lower sides of the separation tank. A hole is defined on the separation tank to connect the liquid storage space and the gas supply space. The gas supply device includes a gas cylinder and a control valve in the gas supply space. The opening of the gas cylinder is toward the bottom. The gas is transferred from the gas cylinder, through the control valve and the hole of the separation tank, to the liquid storage space. The invention has the advantages of increasing the dissolved gas in liquid, great safety in use, easy operation, reducing the gas escape rate, and customization in use.

A beverage container for a nitrogenated beverage comprises at least two restricted outlet apertures (11, 12) configured to, when pouring therefrom into a secondary vessel, form jets of beverage that impinge downstream. Impingement initiates nucleation of dissolved nitrogen gas in the beverage and, as such, when poured into the vessel a creamy head of fine nitrogen/mixed gas bubbles can be formed. The restricted outlet apertures can be formed in a plate (10) over an openable mouth of the beverage container, or directly upon the container. Preferably a vent (14) or some other means is included to increase the velocity of the jets.

A container closing device for a beverage can having an opening tab which is disposed on a can lid and pivotable about a pivot reception formed in a lid bottom, the opening tab being provided with a reactive surface on its underside facing the lid bottom for contact with a liquid pouring from the pouring opening, a sealed space being realized in the area of the reactive surface and a closing piece disposed in the lid bottom between a pouring protrusion and the lid bottom so that the reactive surface is disposed at least partially in the sealed space and is sealed against the environment.

The present invention is directed to a container (C) for the preparation of flowable food or beverage compositions, adapted to be functionally inserted in a food or beverage preparation machine (M), said container comprising walls defining at least one cavity (27) for containing at least one precursor ingredient, and a dispensing channel (15) through which the food or beverage composition can flow to a consumer receptacle, characterized in that it further comprises a foaming whisk element (29) located at least partially into the dispensing channel (15) so as to be able to whip said product when the latter exits said channel (15).

A flexible and hingeable valve mechanism is provided to a package or pouch, e.g., a package top seal, creating one or more channels through the top seal of the pouch and then, approximate to the one or more channels, making or forming a pocket within the same seal. As the pocket is filled with gas, it can prevent the top seal from accidentally kinking and allow other gas pressure to flow freely through the one or more channels. If the pouch is tilted or tipped over, the pocket will fill with the liquid content of the pouch and the weight of the liquid within the pocket will cause the pocket to hingeably displace and close off at least a portion of the one or more channels to prevent leaking or spilling.
