A reusable vessel comprises a first compartment to store therein a substance and a second compartment separated from the first compartment by a boundary element comprising a wall or membrane having one or more apertures therein. A valve is movable between a closed position, in which the valve seals the one or more apertures, and an open position allowing the substance to be released from the first compartment into the second compartment, or a substance in the second compartment to mix with the substance in the first compartment. A triggering mechanism is coupled to the valve to move the valve between the open and closed positions. The triggering mechanism comprises one or more external elements coupled to one or more internal cam elements to control the valve, which, when triggered causes the one or more external elements to exhibit a visible change to indicate the open and closed positions of the valve.

A cap assembly for a refill capsule and associated refill system is disclosed. The cap assembly (200) comprises an inner wall (202) defining a conduit (203) through the cap assembly (200) and an outer wall (204) surrounding the inner wall to form a circumferential void between the inner and outer walls (202, 204). A connecting wall joins the inner and outer walls (202, 204). The cap assembly (200) further comprises a closure member (208) which is sealed to the inner wall (202) with a peripheral frangible connection (210). The frangible connection (210) is disposed between radially offset portions of the inner wall (202).

In one aspect, new dispenser components for use with portable fluid dispensing apparatus are provided. The present systems can by used to administer to a user water and other fluids optionally together with one or more other ingestibles such as flavoring, or a health supplement. In another aspect, new rotor or disk units that may comprise one or more pods or packets that contain ingestible material(s). In a further aspect, one or more of such pods or packets that may comprise one or more ingestible materials.

A plug for use in a cap assembly of a refill capsule is disclosed. The plug (300) generally comprises a hollow tubular body (302) with an open proximal end that is surrounded by a first rim (304) that provides a proximal abutment surface for bearing against a frangible sealing component of a cap assembly. A tubular skirt wall (306) is arranged coaxially with respect to the tubular body, and extends around the skirt wall (306) to form a plug recess (308) between the skirt wall (306) and the tubular body (302). The skirt wall (306) extends from a skirt distal end at which the skirt wall (306) is connected to the tubular body (302), to a free proximal end. The free proximal end of the skirt comprises an outwardly extending flange (310) comprising a distal facing abutment surface (312) for abutting a rim (406) of a refillable vessel (400).

Disclosed is a mixing container capable of mixing and discharging two different types of contents. The mixing container according to one aspect of the present invention comprises: a main body part having an inner space therein; a rotating part rotatably coupled to one end of the main body part; a moving part that is screwed to the rotating part and can move linearly by means of rotation of the rotating part in the inner space; and a pressing part that is provided in the main body part and is elastically deformed by an external force so as to reduce the volume of the inner space, wherein the inner space is divided, by the moving part, into a first space filled with a first content and a second space filled with a second content, the first space and the second space communicate with each other by means of movement of the moving part such that the first content and the second content can be mixed, and the mixed contents are discharged by means of elastic deformation of the pressing part.

Disclosed is a mixing container for using two types of contents by mixing. A mixing container according to an aspect of the present invention has: a first body having a first inner space; and an insertion head inserted below the first body. The insertion head comprises: a second body which has a center protrusion having a through hole and protruding downward by a fixed length; a piston which forms a second inner space by being movably inserted into the insertion head and closes the through hole by coming into contact with the center protrusion; and a bottom cap which covers the bottom of the second body. The center protrusion is released from the contact with the piston by means of the descent of the piston due to an external force, and thus the first inner space and second inner space communicate.

Liquid mixing apparatus includes a housing having an open lower end and a pour opening normally sealed with a closure. A bottom assembly extending across the open end of the housing and sealingly engaged in the open end for relative rotation between the housing and the bottom assembly. The bottom assembly forms a liquid sealed cavity with the housing and further includes apparatus for removably attaching the bottom assembly to a liquid container. A mixing opening defined in the horizontal wall with a flapper valve pivotally mounted therein for pivotal movement between a closed orientation and an open orientation. A stop bar attached at a lower surface to the upper surface of the horizontal wall and extending across a mid-portion of the mixing opening. An activating bar affixed to the housing for rotation with the housing.

The subject matter described herein includes a container having a substantially tubular body forming a first volume for receiving a first fluid. The body includes a first and a second end, and the first end includes a dispenser provided with an aperture making it possible to dispense the contents of the container. The second end includes a closure element having a flexible wall making it possible for the flexible wall to be displaced between a first and a second position relative to the dispenser in order to thus dispense the contents of the container. The container includes a capsule with an outer wall forming a second volume for containing a second fluid. The capsule is positioned between the dispenser and the flexible wall respectively. The capsule is suitable for releasing the second fluid into the first volume during or after a first displacement of the flexible wall from its first position towards its second position.

A dual compartment mixing and drinking container may include two vertically stacked first and second compartments separated by a membrane or seal, each containing one dry or liquid component of a final mixed drink. In operation, each compartment holds one component to be mixed with the other compartment. The container may include a means for opening the container that may also simultaneously puncture the membrane such that the first compartment and the second compartment may be in fluid communication with one another in order to mix the two components upon opening the container.

The device of the present invention includes a compact baby bottle attachment. The device of the present invention is a pod that is functional as a cap to a baby bottle, a storage container for powdered formula, and a dispenser for powdered formula. The device is removably attachable to conventional baby bottles and eases the baby feeding process by storing powdered formula separately from the water reservoir, sealing the powdered formula compartment with a ring plug, and including a nip housing depression to ensure the nip is erect and ready to feed upon removal of the pod.
