Provided is a container with which its body can be deformed with a same external force until most of the contents has been discharged from the container body and to cause the final shape after the deformation to be a constant shape. Also provided is a container with which the contents discharged can be rendered constant, thus making it possible to obtain a diluted product having a constant concentration. The container includes a bottomed container body and a lid member, the container body and the lid member being sealed by an annular seal portion. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. There is also provided a deformation controlling recess whose width is progressively reduced from a back face side of the flange toward the bottom face side.

A container is provided that includes a container body and a lid member, the container body and the lid member being sealed by an annular seal portion. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. The annular seal portion is formed by a pressing operation of pressing the lid member against the flange via a seal bar having at its leading end an annular projection having a shape corresponding to the annular seal portion, a groove-like sunk portion corresponding to the annular projection being formed in the flange by the pressing operation. At least a portion of the sunk portion formed in the detaching seal portion comprises an uneven groove having a cross sectional shape with a smaller curvature radius on its radial inner side than its radial outer side.

A mixing pouch forms a packaging product that includes a first compartment containing a supply of a liquid ingredient and a second compartment that contains a supply of a powdered ingredient with a breakable seal between the two compartments to separate the two ingredients. Rupturing the breakable seal creates a common interior cavity and allows the mixing of the two ingredients to create a mixed product. One end of the mixing pouch is formed with a dispenser through which the mixed product is dispensed for use. An apparatus, such as a positionable clamp or an adhesive strip on the exterior of the mixing pouch, can reduce the size of the common interior cavity to facilitate the dispensing of the mixed product. Preferably, the mixing pouch is a flexible plastic member having a dispensing end formed with a channel closed by a tear-away portion.

Described is an automated reagent mixing container for separately storing and automatically mixing together at least two stored reagent components.

An adjustable additive cartridge that provides adjustable metering of additive to a base fluid as the base fluid is flowing through the cartridge. A spout is mounted for limited rotation within a base element of the cartridge. Rotation of the spout results in varying degrees of flow of additive into a base fluid flow path through the cartridge. The cartridge may be used with a portable beverage container, such as a sports bottle or off-the-shelf water bottle. The supply of base fluid in a container used with the cartridge may be kept in an unmixed, pure state, and other cartridges, each having different additives (i.e., flavors) may be used interchangeably with the same base fluid supply. The cartridge allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid in a single container. A check valve on the cartridge prevents backflow of the base fluid. An integrated filter for filtering base fluid flowing into the cartridge may be provided. The additive cartridge may be sealed to provide for extended storage and to provide a user/consumer with evidence of integrity, quality and/or tampering prior to purchase and/or use. Visual and tactile indicators of the amount of additive being added to a base fluid may be provided. A container may retain a spare additive adjustable cartridge on the container.

A rotating cup, both hands implement relatively forward and backward rotation to generate agitation effect, for mixing powdered material with liquid and stirring food material, such as egg liquid, especially suitable for the open air. The rotating cup comprises an inner cup, a first outer cup and a second outer cup which are coaxially superposed. A fixed axle penetrates through the center of circle of the first outer cup, and both ends of the fixed axle are fixed to the centers of circle of inner cup and the second outer cup, so that the second outer cup and inner cup are interlocked, and the first outer cup can idle. The rotating cup can be equipped with a transmission structure and a stirring rod simultaneously or respectively. On the one hand to provide unidirectional rotation effect and acceleration effect for quick mixing, on the other hand to provide a better agitation effect.

A baby bottle blender includes a baby bottle having a top collar and a bottom collar, and a nipple. The nipple cap is removably attached to the top collar of the baby bottle and holds the nipple extending through a central aperture of the nipple cap onto the top collar. An agitating unit is centrally retained within a bottom attaching cap. A base member has a top recess to engage the agitating unit. An electrical mechanism in the base member operates the agitating unit, so that the agitating unit will thoroughly blend a formula in a liquid in the baby bottle in approximately seven seconds.

The present invention provides emulsions as well as compositions and methods for making the same, which are characterized by an ester component, a non-ionic surfactant component and a water component and wherein emulsification using a low or ultra-low energy method such as shaking by hand is possible to obtain a storage stable emulsion with small particle sizes.

A drinking container has a lid that attaches to a vessel. The lid has a sidewall that forms a chamber with an opening. A spring-loaded door is pivotable between a closed position that seals the chamber opening from the vessel and an open position that allows transfer of fluid or solids between the chamber and the vessel. A lever has a catch that engages and holds the door in the closed position unless the lever is actuated by the user. The lever can be actuated by the user through an area on the lid that allows operation of the lever from the exterior of the container. The drinking container may include additional chambers with corresponding spring-loaded doors that are released through an area on the lid.

A water bottle system for adding an additive, which may be flavoring, to the line of flow without contaminating the main reservoir. The system may include a water bottle with a lid feature that may maintain a flavor that may be infused into the water within the water bottle. The infusion of the additive may be adjusted by a user to have the desired concentration of additive to a user's liking. The additive cartridge may be reusable or disposable depending on a user's preference.
