A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. Pre-caching web content in this manner provides web content to the mobile device that the user of the mobile device is likely to access. The preform includes a first edge proximate the first face sheet, a sidewall extending from the first edge to a flange extending substantially perpendicularly from the sidewall. The lower track may include a concave depression proximate to the dispensing area that retains a first container at a lower relative position, thus enabling the first container to act as a stopping mechanism to subsequent containers placed in the system.
