    Abstract: A suction cup comprises a suction cup member, a press ring, a first housing and an insertion pin. The suction cup member includes an assembly surface and a suction surface. The assembly surface includes a first protrusion having a first cut-out slot formed thereon. The press ring is pressed onto an upper outer edge of the suction cup member. The first housing is pressed onto the press ring and includes a second protrusion for mounting onto the first protrusion. One side of the second protrusion includes a first through hole corresponding to the first cut-out slot to expose the first cut-out slot. The insertion pin partially engages with the first housing and slidably engages with the first through hole and the first cut-out slot to move in the first cut-out slot and to drive the suction cup member to move upward while forming a vacuum space underneath thereof simultaneously.

    Abstract: A storage container includes a container body, a lid, and a dividing member. The container body defines an accommodating space that has a top opening. The lid is removably disposed on the container body, and has two covering sections that cooperatively cover the opening. Each one of the covering sections is independently operable to uncover a part of the opening. The dividing member is removably disposed in the accommodating space for dividing the accommodating space into two compartments.

    Abstract: A food container includes a box, a cover and a pair of locking wings. The box includes a main body and elastic engaging plates. The main body has a receiving space. The elastic engaging plates are arranged on opposite sides of the receiving space. Each elastic engaging plate includes an elastic arm and a clip. The cover includes a cover plate and engaging slots. The cover is positioned on the main body through the clip inserted in the engaging slot. The locking wings are pivotally coupled to the cover. Each locking wing rotates toward the box to press elastic arms. The elastic arms drive the clips to be disengaged from the engaging slots. Thus, the cover is separated from the box.
