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.
