  • Patent number: 11787610
    Abstract: A child-proof container includes a casing, a drawer, a folded stopper, a rear brace, a front brace, and an elastic flap. The rear brace is connected across a bottom panel of the casing and positioned offset from a rear panel of the casing. The front brace is connected across the bottom panel and positioned offset from a front opening of the casing. The folded stopper being elastically integrated into a base plate of the drawer thus allowing a first lateral plate and a second lateral plate of the drawer to be slidably engaged within the casing. The elastic flap is integrated into the bottom panel so that the folded stopper can be operatively positioned in between the rear panel and the front brace through the elongated flap to selectively position the drawer in a close-locked position, a close-unlocked position, and an opened position.

  • Publication number: 20200283204
    Abstract: Described herein is a packaging clip for releasably securing overlapping packaging panels to one another. The packaging clip includes a biasing element that helps restrain relative movement of the panels in a first configuration, and in a second configuration encourages their release and indicates such to a user. In an implementation, the biasing element is associated with a locking mechanism. The locking mechanism includes a rigid portion that is engageable with each overlapping panel for limiting their relative movement in the first configuration. The locking mechanism is turnable or otherwise manipulateable to release the first and second panels. The biasing element can exert a biasing force that encourages exit of the locking structure, allowing the locking structure to protrude from the panels and provide a visual indication of the released state.
