An internal container for storage of a first substance and in use with an external container for storage of a second disparate substance is provided. The internal container may be stored within the external container while keeping the first substance and the second substance separated until a predetermined time. At the predetermined time the first substance and the second substance may be mixed by continuously accelerating or shaking the external container without any direct user contact with the internal container.

A bottle assembly for storing and mixing liquids includes a lid having a removable screen member. The screen member can have resilient tab members, which in turn, comprise inwardly protruding retaining members for use in attaching the screen member to the lid. The screen member can be convex in shape relative to the lid and can be partially spherical, or approximate a partial or half sphere. Also, in some embodiments, the screen member includes reinforcement structures proximate the resilient tab members for preventing over extension of the tab members.

Provided are methods and systems for delivering a treatment fluid to a wellsite. An example method includes receiving a container containing a treatment fluid component from a treatment fluid component supplier. The method further includes introducing the treatment fluid component into a wellbore from the container by pumping the treatment fluid component out of the container and into the wellbore. The treatment fluid component is not transferred to another container during the receiving or the introducing.

A pod for holding a powder to be mixed with a liquid, the pod comprising a body having an opening for loading the powder into the body and a detachable lid that covers the opening, the lid comprising one or more holes, and one or more movable hole covers that, when repositioned, expose the holes.

Disclosed is an ingredient dispensing system for dispensing an ingredient into a container. The ingredient dispensing system communicates with a computing device over a communication network. The container includes a neck and stores material. The ingredient dispensing system includes a cap, a printed circuit board, a controller, a dispenser, a battery, a battery holder and a housing unit. The controller is connected to the printed circuit board and is further programmed to release signals. The dispenser connected to the printed circuit board dispenses the ingredient on receiving the signal from the controller. The housing unit includes a compartment for storing supplements and a nozzle to release stored supplements through the neck on receiving pressure from the dispenser into the container. Further, the ingredient dispensing system includes a collector assembly for receiving ingredients from the nozzle.

A compartmented bottle has a primary compartment and at least one secondary compartment. The primary compartment has an exhaust aperture and an inlet aperture, and the secondary compartment has a secondary exhaust aperture. The inlet aperture of the primary compartment and the secondary exhaust aperture of the secondary compartment are fluidically connected by an inter-compartmental conduit, and a selectively actuated inter-compartmental valve is disposed in the conduit. The valve, which could comprise a cylindrical valve, has a closed condition wherein the secondary compartment is sealed and an open condition wherein the secondary compartment is in fluidic communication with the primary compartment. A toroidal collar can bridge an annular channel between the primary and secondary compartments to establish a continuous cylindrical surface. The valve can be operated by a handle disposed at a distal end of an actuation rod that is drivingly engaged with the inter-compartmental valve.

A modular beverage container assembly is an apparatus designed to store beverage ingredients separate from each other in the same structure. The apparatus includes a drinking lid, a solvent receptacle, a dispensing cap, a solute container, a lid-interlocking snap feature, a receptacle-interlocking snap feature, a cap-interlocking snap feature, and a container-interlocking snap feature. The drinking lid enables the consumption of the desired beverage. The solvent receptacle retains the liquid base for the desired beverage. The dispensing cap enables the dispensing of the desired beverage ingredients from the solute container into the solvent receptacle. The solute container stores the beverage ingredients that can be mixed with the liquid base. The lid-interlocking snap feature and the receptacle-interlocking snap feature enable the removable attachment of the drinking lid to the solvent receptacle. The cap-interlocking snap feature and the container-interlocking snap feature enable the removable attachment of the dispensing cap to the solute container.
