In one embodiment, a container includes a base and a lower wall section extending upward from the base. One or more upper wall sections are stacked on the first wall section. A pair of flanges may extend perpendicularly from outer edges of the lower wall section and the upper wall sections. An upper door may be hingeably connected to one of the flanges of the second wall section. A lower door may be hingeably connected to one of the flanges of the lower wall section.

A collapsible container includes a base and a plurality of walls pivotable between an upright position and a collapsed position on the base. A first wall includes an opening therethrough. A first door selectively covers the opening through the first wall. In one embodiment, the first door is slidable between an open, retracted position away from the opening and a closed position covering the opening.

The present invention is a dispenser that is secured to a structure wall. Back walls of the dispenser are fixed relative to each other such that a first spring mechanism applies a first outward force on at least one wall of the dispenser, a second spring mechanism applies a second outward force on at least one wall of the dispenser, and the first and second outward forces are transmitted to the structure wall through one or both of first and second walls and the back walls. An aperture in the front wall is configured to inhibit flexing of the dispenser when the first and second outward forces are applied to the walls of the dispenser.

A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.
