Abstract: The disclosed systems and methods relate to improved tamper-proof cases for securely storing and shipping products. In one example, a tamper-proof case comprises a unibody frame constructed from a single piece of material. The unibody frame can comprise six sides and include one or more living hinges that allow the unibody frame to fold into a completed case. Various sides can be configured to receive panels to give the crate additional structure, rigidity, and security. Additionally, the frame can comprise a split-top lid with a self-locking mechanism with a tamper-proof pull tab for opening the lid.

Abstract: The invention relates to a container (1) which comprises a first plurality of strips (11-1 to 11-15) which, in the unfolded state, form the base surface and at least one end wall of the container, and a second plurality of strips (12-1 to 12-9, 12-10 to 12-18) which, in the unfolded state, form at least one side wall of the container, the container in the unfolded state having a height, a length and a width, and wherein the container in the collapsed state can be substantially reduced to the width. Therefore optimal compact dimensioning of the container in the collapsed state is achieved.

Abstract: Structures, methods, and systems associated with a stackable and collapsible container are provided. One structure includes a stackable and collapsible container having at least four non-collapsible, load bearing vertical support members attached to vertical walls of the container and capable of supporting the weight of other containers. A top surface is included having a number of sections which include a pivotal connection to one another and which are collapsible about the pivotal connection to an interior of the container. A bottom surface is included having a number of sections which include a pivotal connection to one another and which are collapsible about the pivotal connection to an interior of the container. The top and the bottom surfaces of the container can be fixedly positioned in a number of collapsed states.

Abstract: A rack for holding articles includes a plurality of sets of vertical battens, a plurality of sets of horizontal battens that are clamped together with the plurality of sets of vertical battens, a long connecting screw piece that extends through each set of horizontal and vertical battens, and a supplementary connecting screw that connects the front horizontal batten and the front vertical batten. The screw piece defines a pivot axis for folding the battens.

Abstract: A structure that is collapsible from a volume-enclosing, expanded position to a position wherein the walls and roof are disposed in a horizontally extending stack of generally vertically disposed members. The roof is pivotally mounted to an upper portion of a free-standing rear wall (which is operatively connected to the ground in free-standing position), and the front wall is pivotally connected to the roof generally along the front edge of the roof. A floor may be provided having at least a portion thereof pivotal with respect to the rear wall so that it can be disposed generally parallel or perpendicular to the rear wall. The side walls may be mounted to the rear wall so that they pivot outwardly with respect to the rear wall, the rear wall being disposed between the side walls and the front wall when the structure is in collapsed position. An interior partition can be provided in the structure, and mechanisms may be utilized for interconnecting two such structures together.

Abstract: Folding structures useful for a variety of different utilitarian and play purposes can be constructed so as to utilize a Sarrus linkage modified so as to include an overcenter toggle mechanism to reinforce the linkage against inadvertent or undesired folding from an expanded position. As used in accordance with the invention such a Sarrus linkage includes two non-folding members or walls which are connected by two separate folding wall structures. Each of such wall structures includes two non-folding parts, an intermediate hinge connecting such parts, and edge hinges connecting such parts to the non-folding members or walls.

Abstract: A child's playhouse, or the like, particularly designed and constructed for being folded into a compact storage position when not in use and readily expandable to a complete playhouse type structure when in use. The structure may be permanently mounted on a wall, or the like, in such a manner that when the apparatus is in the storage position, the entire structure is unobstructive and may be either a decorative feature for the room wherein the apparatus is located, or may be a useful object therein, such as a chalk board, or the like.
