An airtight bag is provided for preserving a first substance and at least one second substance. A first opening device is provided for providing a first opening and an access by a user to the first substance in the bag, and at least one second opening device is provided for, subsequent to accessing the first substance via said first opening, providing at least one second opening and an access by the user to the at least one second substance in the bag. The first opening device is positioned such that first opening facilitates the access by the user to the first substance. The at least one second opening device is positioned such that the at least one second opening facilitates the access by the user to the at least one second substance.

A dispensing system includes a device having a body extending along a longitudinal axis between opposite proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.

The disclosure relates to a drinking device that comprises two separate compartments, a first compartment for holding a flavored beverage or a flavoring agent for reconstituting the flavored beverage and a second compartment for holding an unflavored or weakly favored beverage, and a switching mechanism that allows for the sequential consumption of beverage from the first and the second compartment such that a subject ingests, in the course of each drinking event, first a volume of the flavored beverage and thereafter a volume of the unflavored or weakly favored beverage. Drinking from the device conveys to the subject a sensory experience that is similar to that produced by a typical uniformly flavored beverage even though it only consumed a fraction of the amount of flavoring agent that it would have consumed from drinking an equivalent volume of the uniformly flavored beverage.

A self-heating or self-cooling system and method for providing instant cooling or heating to a product or a surrounding area. The system can include an outer container that is configured to slidably receive an inner container. A piercing member extends from a bottom wall of the outer container and is configured to pierce, break or rupture a sealed end of the inner container so that at least two separate liquids can mix to either create an exothermic reaction that produces heat or an endothermic that absorbs heat or has a cooling effect. The inner and outer containers can be lock in a closed position when the inner container is pushed into the outer container. A sealing arrangement is configured between an interior surface of the outer container and an exterior surface of the inner container to prevent leakage of fluid from the interior chamber of the outer container.

A container is provided. The container includes a body, a first plug, and a second plug. The body has a first end, a second end, and a bypass with a length L disposed between the ends. The first and second plugs are slideably disposed in the body and define a first compartment. A second compartment is in the body between the second plug and the second end. The second plug has a first edge; a second edge; and a plurality of primary conduits, each primary conduit extending from first openings in the side wall to second openings in the bottom surface. The bottom surface does not define a plane oriented substantially orthogonal to the longitudinal axis. A distance D extends longitudinally from the first edge to the second edge. A distance E extends longitudinally from the first edge to the first opening. D≧L and E<L.

The present application relates to milk powder packaging field. The present application provides a powder dispensing apparatus for dispensing fixed amount of powder, including a powder outputting member, a bottle mouth connecting assembly and a plurality of resetting members, the powder outputting member has a powder outlet, the bottle mouth connecting assembly includes a valve and a bottle mouth connecting member, the bottle mouth connecting member has a sliding groove, each the resetting member is located in the sliding groove, one end of each resetting member is connected to the bottom of the sliding groove, the other end is connected to the powder outputting member, the valve and the powder outlet are detachably connected, a side of the bottle mouth connecting member deviating from the valve is connected to the powder storing bottle. The present application improves the accuracy of fixed amount of powder dispensing.

A portable container, which contains a lower container body for storing a liquid, and an upper container body detachably connected to the lower container body. The upper container body adapted to store solid substance. The upper container body further contains a user-configurable opening device which is switchable between a first state and a second state. In the first state the opening device prevents the solid substance in the upper container body from falling into the lower container body. In the second state the opening device allows the solid substance to fall into the lower container body in order to mix with the liquid. The portable container not only separates the milk powder and warm water before brewing, but it also maintains the water at an appropriate temperature and to maintain the dryness of the milk powder. The warm water and the milk powder can then be mixed at any time to brew the milk suitable for drinking.

A mixing container and a method for the manufacturing thereof provide a mixing container which offers high pressure-resistance performance while allowing the sealing membrane to be easily broken when the containers are coupled together, by having the sealing membrane formed in an integrated manner with the metallic bottle end and arranging a breaking line on the sealing membrane. Also, the method for manufacturing a mixing container with which the time and effort required for manufacturing the mixing container may be reduced, to allow mass production at a low cost, as the holding body made from a synthetic resin material and the bottle end made from a metallic material are manufactured separately and subsequently seamed together.

An extended duration anesthetic includes a short duration local anesthetic in a dilute solution and a long duration local anesthetic. The long duration local anesthetic is maintained in a powdered form until the time of administration. Premeasured quantities of the dilute solution and powdered long duration local anesthetic in a kit allow for quick preparation of a solution with desired concentrations of both short duration local anesthetic and long duration local anesthetic at the time of administration.
