Childproof package
InactiveUS7757843B2High dexterity thresholdIncrease the difficulty of openingSmall article dispensingTobacco devicesEngineeringFinger operation
Childproof packaging for a product such as matches or pharmaceutical tablets includes a sleeve and a container for the product within the sleeve. The package includes two pairs of latches, with each latch of a pair oppositely located on the package. A user must use both hands simultaneously, with a respective hand operating a respective pair of latches, to hold the latches in an unlatched condition and also simultaneously to apply pressure to the container to slide it outwardly relatively to the sleeve. Such a two-handed, five finger operation to open the package requires a dexterity that is easy for adults but very difficult for children. Each latch may be a spring arm mounted tab or button which seats in an aperture in the sleeve.

The invention provides a storage battery anti-theft mechanism suitable for a transport vehicle and having a cooling function, relates to the technical field of vehicle-mounted storage batteries, and solves the problems that two ends or the middle of a storage battery are directly welded by steel through electric welding in traditional storage battery anti-theft treatment of a transport vehicle, the anti-theft effect is poor, an alarm is difficult to give when theft occurs, a lock is easily pried up by thieves, and property loss is caused. The storage battery anti-theft mechanism comprises an anti-theft cover plate, a driving rotating block and a power-off alarm. A breathable base is fixedly mounted at the bottom of a protective box, four buffer plates are mounted in the top of the breathable base, and the buffer plates are hollow; and the interior of the protective box is hollow. A special wrench drives the driving rotating block to rotate, so that a connecting rod connected with the driving rotating block drives a locking rod to move outwards, the outer end of a guide sliding block is inserted into locking holes in the left end and the right end of the top of a protection cavity, the anti-theft cover plate is fixed, the opening difficulty of the anti-theft cover plate is increased, and the anti-theft protection coefficient of an internal storage battery is improved.
