Flat primary and secondary locking system
InactiveUS7175020B2Flat bottomContainer/bottle contructionMetal working apparatusEngineeringMechanical engineering
A new type of secondary locking system for article carriers consisting of at least one secondary male lock with two shoulders that is attached by a neck to the edge of a outer flap on the carrier for use with a primary locking system. An inner flap has a secondary female opening for each secondary male lock. The secondary female opening is formed by a secondary cut line and fold line with the center of the fold line projecting towards the edge of the flap while of the center of the secondary cut line projects away from the edge of the flap to guide the secondary male lock into a flat position against the inside of the inner flap. The shoulders on the secondary male lock are engaged against locking ledges along the extensions of the secondary cut line. A pair of slits may be formed at the end of the fold lines that project inwardly to allow the secondary male lock to slide into a flat position. This locking system is especially useful in wrapping containers that have a flat bottom that would interfere with conventional locking systems.

Tunable left-handed metamaterial based on phase-change material
The invention provides a tunable left-handed metamaterial based on a phase-change material. The phase-change material is introduced into the left-handed metamaterial based on a multi-layer structure, so that a working band with a negative refractive index of the left-handed metamaterial is enabled to have tunability, and the technical problem that the working frequency range of the left-handed metamaterial is narrow is solved. By the characteristic that the dielectric coefficient of the phase-change material is changed along with the change of an external electric field or temperature, the tunable function of the working frequency of the left-handed metamaterial is realized, and the maximum tuning amplitude can reach 43%.
