Abstract: The present disclosure describes a container, applicator device, or apparatus with one or more product holders that rotate open via a set of connecting hinges located on either the faces or sides, and containing a locking system located on front or back faces of the container. The device opens by rotating a lever, with an attached cover, in the direction of the face, and using the connecting hinges to lift out the product through an orifice.

Abstract: The present disclosure describes a modular primary device with removable product encasements. The device includes a removable encasement that is inserted into a modular unit. The device is configured such that it can connect to a second modular unit via connectors attached to the respective encasements. The user can open and close the device and, connect and disconnect one modular unit from an adjacent modular unit by manipulating the connectors which also act as hinges. The innovation is especially suitable for devices having portions composed of materials such as paper, wood, and glass, whose characteristics do not allow tight tolerance dimensioning.

Abstract: The present disclosure relates to containers having positional lock coupling. In accordance with aspects of the present disclosure, a positional coupling device includes at least one protrusion protruding from and fixed to a first surface, and at least one hole fixed within a second surface where the at least one hole corresponds to the at least one protrusion and is configured to receive the at least one protrusion. When the first surface and the at least one protrusion are rotated relative to the second surface and the least one hole, the at least one hole receives the at least one protrusion in at least two distinct rotational positions.
