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 system and method for mud mixing using a container to hold a joint compound and the water. The container having a lid to keep the container shut and preventing the liquids from escaping wherein the container may then be shaken by the user to mix the joint compound with the water. The user then may remove lid and pull on a rod and plate connected to one another at the bottom of holding container. Rod and plate act as a pressure seal, whereby when the rod is pulled all of the mud may be removed from the container and placed into a pan for use.

A device for mixing liquid material which a user shakes by hand up and down or left and right is provided. The device includes: a container that includes a space on an inner side extending in the longitudinal direction, and a grip shape on an outer side of the container; an opening-closing member; and a coil spring which has a constant winding diameter and moves freely inside the container in the longitudinal direction. Liquid material and the coil spring are contained in the container, the liquid material being obtained by mixing a material to be dispersed and liquid. A silencer is provided at the end of the coil spring. The device includes: a coil spring abutting part that abuts against and supports 80% of a planar spread formed by one winding of an end of the coil spring relative to the one winding; a first vertical wall and a second vertical wall which are two vertical walls which are perpendicular to the coil spring abutting part and also perpendicular to the coil constituting the coil spring, and are provided at limiting positions where the coil spring of the coil spring abutting part abuts; and a cylindrical wall that extends vertically opposite to the coil spring of the coil spring abutting part, and has an inner diameter set to be the outer diameter of the coil spring, wherein the first vertical wall and the second vertical wall each have two holes through which a coil constituting the coil spring can pass arranged side by side in a direction in which the coil spring extends.

The present invention relates to a shaker bottle device that has a body and a lid. The body is further preferably comprised of at least one measuring line that indicates a corresponding amount of liquid or solid volume that is within the body, wherein the line is further highly visible using contrasting colors, fiber-optic, fluorescent, or luminescent paint. The body may also be comprised of a weighted bottom surface that prevents the device from spilling. The body and lid may also have at least one magnet that allows the device to magnetically attach to a metal surface or object to further prevent spilling.

An agitator may include one or more members adjustable between an expanded configuration and a compressed configuration. When the one or more members are in the expanded configuration, the agitator in a first set of two orthogonal dimensions is larger than an opening having a predetermined size. When the one or more members are in the compressed configuration, the agitator in a second set of two orthogonal dimensions is smaller than the opening having the predetermined size. The one or more members are biased to the expanded configuration in absence of external force applied to the one or more members. In use, the agitator may be inserted into a container through a neck of the container in the compressed configuration. The agitator may expand within the container so that the container does not fit through the neck of the container.

The disclosure describes methods and devices with which to process and analyze difficult chemical, biological, environmental samples including but not limited to those containing bulk solids or particulates. The disclosure includes a cartridge which contains a separation tube as well as one or more valves and cavities for receiving raw sample materials and for directing and containing various fluids or samples. The cartridge may contain a separation fluid or density medium of defined density, and structures which direct particulates toward defined regions of the cartridge. Embodiments can include a rotational device for rotating the cartridge at defined rotational rates for defined time intervals. Embodiments allowing multiple assays from a single sample are also disclosed. In some embodiments, this device is used for direct processing and chemical analysis of food, soil, blood, stool, motor oil, semen, and other samples of interest.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

Provided are methods and devices for dissolving solid protein compositions, such as solid compositions comprising fibrinogen, in an aqueous solvent. The methods comprise use of a closed container containing a volume of solid fibrinogen composition and a head space wherein the pressure within the headspace is sub-atmospheric. Aqueous solvent is introduced into the container while maintain the sub-atmospheric pressure, and subsequent to addition of the solvent, the size of the headspace is decreased to bring the pressure to atmospheric pressure. The devices are suitable for use in the disclosed method.

An agitator for disposition within a cavity of a vessel body containing a particulate includes a weighted portion and a stirring portion. The agitator is positioned and disposed relative to the vessel body to move the stirring portion through the particulate in response to movement of the weighted portion in response to gravitational and/or inertial forces acting on the weighted portion due to movement of the vessel body. Particulate storage vessel arrangements and methods of particulate mixing are also described.
