Abstract
This is an improved container having slidable storage cases propelled by a leaf spring into an open position after pushing down on a front catch. The container comprises a front half, a rear half and a handle, each molded from plastic. The front half and the rear half of the container are ultrasonically bonded together rotatably securing the handle between them. The front and the rear half have six case slots. The front half case slots are defined by a central vertical divider extending from the top to the bottom of the front half and three rows of horizontal M-shaped plastic dividers. Each M-shaped divider is essentially a spring with a lip on it at the central point of the M-shaped divider. The lip can be pushed down and snaps back into place. The rear half is divided into six case slots by a central vertical divider extending from the top to the bottom of the rear half and six sets of guide rails. Extending into the rear half from the back of the container are six leaf springs, one for each case slot. A case is inserted into a case slot over the lip of the M-shaped divider and between the guide rails in the rear half. The rear end of the case pushes against the leaf spring causing the leaf spring to coil or become tense and push against the rear of the case. The front lip catches the front end of the case and holds the case in a closed position. To pop the case out of the container, the front lip is pushed down, the leaf spring releases pent-up tension and the case is propelled out of the container into an open position.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
