Abstract: A child-resistant, tamper-evident closure for a container having an externally threaded neck finish includes a combination of inner and outer caps. The inner cap includes a tamper-evident band which is connected to the inner cap by frangible elements. The inner cap includes folded ratchet-like tabs which are locked in position behind an annular bead. The tabs are arranged so as to engage an annular lip on the neck finish. The outer cap snaps over the inner cap and includes a series of ratchet-like lugs which are directed toward the inner cap. The top surface of the inner cap includes a series of cooperating ratchet-like lugs. So long as a downward force is not exerted on the outer cap, the child-resistant arrangement permits the outer cap to turn relative to the inner cap in a counterclockwise direction. However, when a sufficient downward force is applied, the lugs of the outer cap are drawn into abutment with the cooperating lugs of the inner cap and the outer cap is used to remove the inner cap.

Abstract: An electrical enclosure lid composed of several elongated members nested in such a way that a tortuous air channel is created between each member. The air channel allows heat generated by internal electrical components, such as large power transformers, to pass out of the lid to facilitate convection cooling of the enclosure. Due to the labyrinthine air channel, flames potentially generated inside the enclosure are hindered from passing outside the enclosure. Drainage holes are included on the sides of the lid to allow water to pass over the lid without entering the enclosure. The design is optimized for harsh environments such as a mining operation where large amounts of power are needed in close proximity to workers. The nesting structure provides strong structural support to protect the enclosure in case of a rock fall or a cave-in.

Abstract: A closing device for containers is made of plastic with a tiltable lid linked to a lid support to be attached to the lid or to the container where it can be moved via a hinged connection from a closed position to an open position. The closing device also has a spring on one side of the lid, and a lid support or the container on the other side. The spring is arranged with respect to the tilting axis of the lid which is defined by the hinged connection such that the lid is displaced from the closed position to the open position after having passed a dead center position, due to the pre-stress of the spring. The lid and the lid support or container each have at least one integrally linked abutment. The abutments come into contact with each other in the open position of the lid as a result of being urged into the contact position by the spring.
