A mechanical closure for includes a cap hinged in an oscillating manner about an axis, a pair of tie-rods respectively articulated at their first end on opposite sides of the cap with respect to the axis and hinged at their opposite second end on a corresponding first end of a respective arm. Each arm is provided at its second opposite end with a respective pin, the pins being coaxial and intended to hinge the arms on a neck of a bottle. An arc connects the arms to one another so that the arms may be jointly actuated to rotate about the respective pin. The mechanical closure includes a tamper indicator provided to indicate the first opening of the mechanical closure includes a band which interconnects the arms and/or the tie-rods on the side opposite the arc so as to prevent the arms from oscillating about the respective pins.

A resealable container includes a container top having an opening and a base mating end, a base mating band having a top end and a bottom end; and a detachable base having a top mating end and base bottom. The base mating end of the container top may be afixed to the top end of the base mating band while the bottom end of the base mating band may be configured to detachably mate to the top mating end of the detachable base so as to provide a resealable container with a narrow opening that allows contents of the container to be dispensed in an accurate and controlled manner, while also having a detachable base that provides improved access to the interior of the container to facilitate the ability to fill, clean, or add contents to the resealable container.

A container assembly includes a first container having a first opening, and a second container having a lid wall. A closure hingedly interconnects the first and second containers for swinging movement between a stacked position in which the lid wall overlies and closes the first opening, and an unstacked position in which the lid wall is removed from the first opening. The closure maintains the containers interconnected throughout the movement between the stacked and unstacked positions.
