Definitions

• the present invention relates generally to containers, and more specifically to containers that include a lock and release mechanism.
• a container that includes a lock and release mechanism is desirable in many applications.
• the lock and release mechanism keeps the container locked in a closed condition unless a release mechanism is triggered to open the container.
• the container provides child resistance or is otherwise not inadvertently opened to allow access to the products contained therein.
• the various embodiments of the present invention overcome the shortcomings of the prior art by providing a container with an improved lock and release mechanism.
• the lock and release mechanism includes locking elements for engaging one another such that a base structure and a top structure of the container can be releasably secured to one another.
• the lock and release mechanism further includes a flexible portion of a wall that can be displaced to disengage the locking elements from one another and open the container.
• the flexible portion of the wall and the locking elements are easily formed from plastic or other materials and are integral to the top and base structures.
• a container in an exemplary embodiment, includes a first structure that includes a first wall and a first locking element.
• the container also includes a second structure that includes a second wall and a second locking element.
• the second wall has a flexible portion that can be displaced. A free edge of the flexible portion of the second wall is partially defined by a slot which separates the flexible portion of the second wall from the second structure.
• the first structure can be releasably secured to the second structure to close the container as the first wall is disposed to be adjacent to the second wall and the first locking element engages the second locking element.
• the first and second walls are substantially coplanar or otherwise aligned in a first plane.
• the flexible portion of the second wall is displaces to disengage the engaged locking elements and release the first and second structures from one another.
• the second locking element can be disposed in the flexible portion of the second wall so that the locking element is displaced with the flexible portion of the second wall.
• the locking elements can be any two elements that can engage one another when the first wall of the first structure is properly aligned and adjacent to the second wall of the second structure. Combinations of locking elements include depressions, grooves, apertures, sockets, slots, and the like that receive detents, protrusions, ledges, pegs, extensions, and the like. Further, two or more protrusions can engage one another.
• a groove is defined in the flexible portion of the second wall that is positioned and dimensioned to receive a protrusion that extends from the first wall.
• the flexible portion of the second wall can include a protrusion that is positioned and dimensioned to be received in a groove that is defined in the first wall.
• the second wall includes a recessed portion that defines a ledge such that in the closed position the end of the first wall abuts the ledge and the inside surface of the first wall is in flat face contact with the outside surface of the recessed portion of the second wall. This arrangement facilitates positioning locking elements in relation to one another. However, the ends of the first wall and the second wall can abut one another. In either embodiment, the locking elements are not limited to being defined in the first and second walls but can rather extend from or be attached to the walls.
• the top and base structures of the container are connected by a hinge.
• the top and base structures are hingedly connected to opposite ends of a hinge panel.
• the hinge allows the top and base structures to move relative to one another.
• the top and base structures are not necessarily properly aligned such that the locking elements engage one another.
• means for positioning the first structure with respect to the second structure is provided to properly align the first wall with respect to the second wall such that the locking elements are positioned to engage one another.
• Means for positioning the first structure with respect to the second structure constrains the movement of the first structure with respect to the second structure, for example, in a plane that is substantially perpendicular to the plane defined by the aligned first and second walls. Thereby, the container cannot be manipulated to gain access to the contents of the container or otherwise the lock and release mechanism cannot be inadvertently released.
• FIG. 1 is a perspective view of an exemplary embodiment of a container according to the present invention.
• FIG. 2 is a perspective view of the container of FIG. 1 in an open condition.
• FIG. 3 is a sectional perspective view of the container of FIG. 1 in an open condition.
• FIG. 4 is a cross-sectional view of the container of FIG. 1.
• the container includes a base structure and a top structure that are releasably secured together as locking elements of each of the top structure and base structure engage one another.
• the container further includes a flexible portion of a wall that can be displaced to disengage the locking elements.

• each side wall 136, 138 of the base tray 112 includes a recess 150 that receives a respective extension 152, which protrudes from the inside surface of each side wall 126, 128 of the top tray 110, to secure and align the trays 110, 112.
• the recesses 150 and the extensions 152 provide means for positioning the top and base structures S1, S2 relative to one another and constrain the movement of the top and base structures S1, S2 relative to one another, as described in further detail below.
• the base tray 112 includes an arrangement of receptacles 154 that are dimensioned and positioned to contain and dispense the contents (not shown) of the container 100.
