Title: Child resistant container for storing hazardous materials
IPC: B65D43/16
Filed: 1990-03-23
Abstract: A child resistant box (20) which is composed of a base (23), a lid (22) and a hinge (30) connecting the base (23) and lid (22) together. A latching mechanism is located on each of the two sides of the box for releasably retaining the lid (22) to the base (23). The box (20) can be moved between open, intermediate, and closed positions. The box (20) also includes a means for biasing the lid from the intermediate position toward the closed position. To open the box (20) the lid (22) is compressed to the intermediate position. In this intermediate position, the latching mechanism may be disengaged by exerting manual pressure thereon toward the center of the box (20). Once pressure is exerted simultaneously on both latching mechanisms the lid (22) is released and the biasing means moves the lid (22) at least partially toward the open position. The operation of this box (20) is particularly well-suited for the elderly. Although this child resistant box can house virtually anything, it is particularly well suited for housing a set of blister cards which include a plurality of medicaments to be taken at different times during a therapeutic regimen.

IPC: E04G21/32
Filed: 1990-05-09
Abstract: The device is provided on a guiding rail (1) of a protection against falling which has the guiding rail (1) with a C-shaped profile, open towards the front, and a slide, for extracting the slide from or inserting it into the guide rail (1), with a rail piece (2) which forms a part of the guiding rail (1), has the same profile as the guiding rail (1) and is laterally pivotable about an axis of rotation (6) which extends from front to rear. The pivoting region of the rail piece is limited by a stop to the minimum which is necessary for it to be possible to insert a slide into the rail piece. The axis of rotation extends below the centre of the rail piece, so that the slide can be extracted or inserted only upwards and cannot fall out downwards.

Patent CA-2038912-A1 (CA)
Inventor: KURESHY FAREED
IPC: G01N35/04
Filed: 1991-03-22
Abstract: There is described an analytical instrument for the analysis of fluids such as biological fluids. The instrument includes a fluid dispensing system having a pipette for dispensing fluid test samples and test reagents to assay cartridges. An optical detection system provides a light beam which intercepts a downward travel path of the pipette prior to its reaching the dispense position. Measurement of the intensity of the light beam in conjunction with the position of the pipette enables a controller to indicate the presence or absence of a pipette tip. In addition, interception of the light beam by the pipette initiates a final approach sequence for the pipette to the dispense position above an assay cartridge by a predetermined increment of travel.
