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 portable bottle having an internal mixing compartment for mixing a powder with a liquid includes a portable drinking bottle housing a mixing compartment. The mixing compartment is formed from a rigid perforated material and extends upward into the drinking bottle from its base. The mixing compartment is accessible through an opening in the base of the bottle, and houses one or more agitators. In use, a particulate material is inserted into the mixing compartment chamber with the agitator and liquid is then added to the bottle. The bottle having an internal mixing compartment is shaken to dissolve the soluble components of the particulate material. The liquid is poured or consumed through the top of the bottle. Insoluble constituents of the particulate material are prevented from exiting the drinking bottle through the top. The agitator facilitates efficient dissolution of the soluble components of the particulate material.

A Container For Consumable Liquids Having Chambers For Separating Ingredients And A Mixing Chamber, which is a unitary modular fluid container with a multitude of components, whereby, the segmented contents, such as alcohol, may be combined through an apparatus of mixing.

The invention relates to a concentrated product storage cartridge for a diluting and dispensing container, comprising an external body, with an open lower end having a closing edge on the lower end thereof; and on the opposite end, there are flaps extending above the cylindrical tube of the external body, comprising a quick-coupling means; an opening for accessing the inner region thereof, where is placed an internal plunger, forming a filling region; and, on the upper end thereof, having quick-coupling means to be attached to the cover of cartridge. Said cover comprises upper ring flaps, arranged in order to interlock with the quick-coupling means of the internal plunger, forming a single assembly with an opening that can engage with the flaps of the external body, which are mounted in a way to provide displacement mobility in both directions downwards and upwards in relation to the internal plunger head.

A multi container assembly comprising, a first container having an opening with a first securing means distal to the opening and integrated within an internal cavity of the first container and a protrusion extends upwards towards the opening and a second securing means is disposed on the protrusion, a second container wherein the first end has an opening and a first securing means distal to the opening and a second securing means distal to the second end, and a cap having a first securing means designed to mate with the first securing means of the first container and a protrusion extending downward from the internal cavity, wherein the protrusion has a second securing means designed to mate with the first securing means of the second container, wherein when the cap is secured to the first container and the second container a substantially impervious seal is formed.

Disclosed is a heterogeneous contents mixing container with improved productivity and sealing ability. The heterogeneous contents mixing container includes a container body for containing a second content; a first content receiving member formed in the container body to contain a first content and including an upper separation cap and a lower fixing cap; a shoulder rotatably coupled to the container body; a lift guide member fixed to the container body and formed with a spiral groove; a lift member moving up by a rotation of the shoulder and formed with a lift protrusion; a pump housing moving up with the lift member; a discharge pump moving up with the pump housing to pump the first and second contents mixed with each other; and a push button coupled to the discharge pump to be movable up or down and formed with a discharge outlet.

A removable container for powder or liquid includes a housing, a spilling mechanism and a bypass element. The housing hangs within a bottle and is capable of storing powder within the bottle while being sealed from a precursor liquid held within the bottle. The spilling mechanism enables the powder to spill out of the housing and into the precursor liquid and the bypass element provides the precursor liquid out of the bottle without mixing with the stored powder.

The proposed formula-mixing bottle relates to baby feeding vessels. It includes a first container with a bottom, a second container with a bottom, and a cap. The second container's bottom is formed by a closure member in the form of a raisable disk of a disk valve. The closure member has a screw shaft disposed on one side thereof, and the inside surface of the second container has a seal disposed thereon forming a seat for the disk of the closure member. The screw shaft is provided with a guide groove and is disposed inside a retaining sleeve having an arrester mounted in the opening thereof such as to be capable of interacting with the guide groove, and of restricting rotation of the screw shaft. The proposed bottle has a simplified structure as a result of the use of elements having less complex shapes.

A container system for use with a cosmetic mask that allows the cosmetic mask to be treated with a liquid personal care preparation just prior to using the mask. The container system comprises a container (1), a closure (2) and a strainer (3). When the container is in an upright position, a flowable product (P) in the reservoir does not reach to the level of the strainer. The invention includes a kit comprising a container system as described herein, and a set of dry cosmetic masks that have not been exposed to the flowable product (P).

A segmented food product container for segregating a secondary food product from a primary food product before the segmented food product container is opened and the two ingredients mixed together prior to consumption. The segmented container includes a primary container, defined by cup member, and a secondary container defined by a cylinder having two open ends, at least one end of which is internally threaded. An externally threaded boss is disposed on, or carried by, the base of cup member. When the cylinder is threaded onto threaded boss, the cylinder can then receive the secondary food ingredient. Further, a lid member seals both the cup member and cylinder.
