A device for storing and dispensing a flowable dental composition, comprising: a first layer and a second layer, wherein the first layer and second layer form a first chamber for containing a flowable dental composition, a transition zone, and a second chamber; an applicator retained within the second chamber; wherein the first chamber has a first concave surface formed in the first layer and a second concave surface formed in the second layer; wherein the device includes an inactive state and an active state.

The present invention concerns an electronic smoking device that includes a battery portion (12) comprising a battery (18), an atomizer/liquid reservoir portion (14) comprising a multicameral liquid reservoir (34), and an atomizer (26) operable when connected to the battery (18) to atomize liquid stored in the multicameral liquid reservoir (34). The multicameral liquid reservoir (34) comprises a first chamber (202) comprising an unflavored fluid, a second chamber (204) comprising a flavored fluid, the first chamber (202) and the second chamber (204) being disposed in communication with each other via an opening (206), and a plurality of reservoir walls (208) enclosing the two chambers. A portion of the plurality of reservoir walls (208) enclosing the second chamber (204) comprising a flexible portion (40), the flexible portion (40) when acted upon causing the flavored fluid to migrate from the second chamber (204) to the first chamber (202) through the opening (206).

A container including a storage chamber within which is located at least one concentrated product housed; a mixing chamber coupled to the storage chamber; and a closure element, wherein the storage chamber is isolated from the mixing chamber; the mixing chamber is defined by a body having a longitudinal length defined between opposed ends and along at least a portion of the length of the mixing chamber, the body defines circular bellows, such that the mixing chamber has a collapsed configuration when the ends of the body are urged together and an expanded configuration when the ends of the body are urged apart, the bellows further including a latching arrangement which acts to latch the bellows in their collapsed configuration and/or their expanded configuration; and wherein a first end of the mixing chamber is open and is selectively closable via the closure element.

The present invention provides a safe, disposable and biodegradable chlorine dioxide micro generator that uses water soluble paper and hydrogel or compressed cellulose encased in filter paper pouch. The chemicals are kept in a stabilize form until activated by the addition of water. Multiple levels of protection against early exposure to water such as a foil pouch and an impermeable outer container allow for the safe transportation and storage in small, ready for deployment amounts of the chemicals. Water permeated the chemical pack housing and dissolves the paper walls of the chemical pouch housing and then the water facilitates the reaction between the acid and the sodium chlorite to form chlorine dioxide gas as will be described further hereunder. Absorbent and permeable materials packaged around the chemicals provide for the safe containment of the chlorine dioxide solution, and the expeditious aeration and release of the chlorine dioxide gas, once the chemical reaction has been completed.

A multi-compartment storage bag, including a bottom portion, including a main compartment to store at least one first item therein, and at least one auxiliary compartment removably disposed on at least a portion of the main compartment to store at least one second item therein, a top portion disposed at least partially along an edge of the bottom portion to facilitate gripping by a user, and a plurality of fasteners disposed on at least a portion of the bottom portion to open or close access to at least one of the main compartment and the at least one auxiliary compartment.

Powdered hair bleach individually packaged in pre-measured sizes, weights, or volumes. The powdered hair bleach is encased in a dissolvable substrate. Packages include one or more chambers and include additional compositions.

This disclosure relates to a multichamber device for administration of substances to a patient. The multichamber device comprises a first end comprising one or more ports and a second end opposite of the first end. The multichamber device further comprises a first plurality of septa and a second plurality of septa dividing the interior into a plurality of chambers, the first plurality of septa being parallel with the first end and configured to open, the second plurality of septa configured to remain sealed, the chambers further divided into a main chamber abutting the first end and being wider than the rest of the plurality of chambers and the rest of the plurality of chambers being organized into columns such that the columns extend from the second end to the main chamber and are oriented so that the first plurality of septa are configured to open toward the first end. The disclosure further relates to methods of using the multichamber device.

Concepts and technologies disclosed herein for selectively opening multiple compartment packages and methods for making selectively opening multiple compartment packages. The selectively opening multiple compartment package can include a front layer having two sides; a second layer having two sides; a third layer having two sides; and a rear layer having two sides. Compartments of the selectively opening multiple compartment package can be formed and bound by a second side of the front layer and the first side of the second layer; a second side of the second layer and a first side of the third layer; and a second side of the third layer and a first side of the rear layer. The compartments are configured to be selectively opened.
