Disclosed is a sleeve-type mortise-and-tenon joint structure unit, comprising: an externally wrapping pipe-type frame (1) and several internally supported pipe-type frames (2) disposed in the externally wrapping pipe-type frame. The externally wrapping pipe-type frame is provided with several openings (3). After some or all of the internally supported pipe-type frames are pulled out of an end part of the externally wrapping pipe-type frame, a vacant part (4) is formed in the externally wrapping pipe-type frame, and the openings and the vacant part form a mortise structure. Further disclosed are two applications of the sleeve-type mortise-and-tenon joint structure unit. The above-mentioned sleeve-type mortise-and-tenon joint structure unit has the advantages of requiring no nail or binder, a stable structure, rapid and convenient assembly and disassembly, durability, lightweightness, reusability, and environmental friendliness.

A packaging material is formed from a shock-absorbing plate material and stored in a packaging box with a packaged article. The packaging material includes a base portion and a shock absorbing portion. The shock absorbing portion surrounds three sides of a space along a main surface of the base portion. First and second vertical plate portions of the shock absorbing portion face each other and continue to the base portion. In the shock absorbing portion, a third vertical plate portion continues to the second vertical plate portion, and a fourth vertical plate portion continues to the third vertical plate portion. The fourth vertical plate portion is overlaped on the first vertical plate portion. A hook portion of the shock absorbing portion continues to the fourth vertical plate portion, and has a second cut in which a bottom portion of the first cut of the first vertical plate portion is inserted.

A container is provided for shipping hardware such as door knobs, binges, framing wedges and the like with prehung door and frame assemblies. The container has a substantially rectangular configuration having a closed container portion and a jamb panel that extends from the top of the container that wraps around the outside of one of the jambs of the frame to secure the container to the prehung door and frame assembly. The depth of the container is less than the depth of the cavity side of the prehung door and frame assembly and the front wall of the container fits beneath or flush with the edge of the jamb on the cavity side of the frame.

As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

The present invention discloses a packaging apparatus, comprising multiple packaging elements, each packaging element comprises a slot for receiving a LCD module, and the packaging apparatus further comprises a connecting means for integrating the multiple packaging elements side by side. Therefore, the packaging apparatus can be used for both LCD modules and end-products such as TV, display devices, the packaging cost can be reduced.

A packing member includes a body portion and a shock absorbing member. The body portion includes a bottom face portion that is rectangular in shape and on which a packed article is placed, and a side face portion that is provided continuously with the bottom face portion via folding lines along its three sides. The body portion is assembled by folding a piece of sheet. The shock absorbing member is disposed along one side of the body portion along which the side face portion is not provided continuously with it. The shock absorbing member has a holding structure that keeps the side face portion upright relative to the bottom face portion.

A cushioning material includes: a flat surface section flatly placed on the product; a side surface section provided on a side surface of the flat surface section; and a connecting section that connects the flat surface section and the side surface section in a separated state.

A corner protector is provided with a body with a recess formed in the body. The recess defines a first surface to receive and contact a pane surface of a pane in the recess. The recess defines a second surface angled relative to the first surface and intersecting the first surface to receive and contact a first edge surface of the pane. The recess defines a third surface angled relative to the first surface and the second surface and intersecting the first surface to receive and contact a second edge surface of the pane. The body defines an aperture formed in the first surface and oriented at a convergence of the first surface, the second surface, and the third surface such that the second surface and the third surface do not intersect. The aperture is formed to a blind depth in the body.
