This disclosure relates generally to a pallet that includes a top deck and a support section. The top deck includes a first frame portion and an encasement encasing the first frame portion. The support section includes a second frame portion connected to the first frame portion of the top deck.
The skid, a precursor to the pallet, has been used for ages and is believed to be first used in Ancient Egypt and Ancient Mesopotamia. Skids were used to transport heavy objects and may have been used to construct the pyramids of Giza. Constructed of wood, skids include a platform that is undergirded with runners, making dragging by man or by animal possible. Unlike skids, a pallet, that includes both a top and a bottom platform, became prevalent after the invention of the forklift in the 1920s. Nevertheless, the terms pallets and skids are generally used in modern convention to refer to the same object. Because pallets are reasonably low cost, lightweight, and durable as well as being extremely convenient to use with a forklift, pallets are the standard for transporting large, heavy, or awkward items. As a result, pallet usage has become ubiquitous in the transportation industry.
Pallets are generally categorized in four different ways: fork entry point, decking, design, and construction material. These different categories highlight different functions and advantages of different pallets. First, the fork entry point may include either a two-way entry point or a four-way entry point. This indicates openings in the pallet that allow a fork to be positioned under the pallet which is accessible from two or four sides of the pallet. A four-way entry point is more accessible but is structurally weaker than a two-way entry point. Second, in the decking category, there is usually a solid deck or an open deck. An open deck means that on the top deck there are spaces between the deck boards and a closed deck means there is little or no spacing between the deck boards. Third, pallets categorized by design usually focus on the spacing structure that attaches the bottom deck to the lower deck. This attachment is usually done by stringers or blocks. The stringers and blocks create space to allow entry of forks into openings in the pallet. Different pallets are identified based on where the support is allocated. Finally, pallets can be categorized by the material used in their fabrication. Pallets, conventionally, can be made of wood, metal, plastic, and compressed paper (cardboard).
Some of the common issues with pallets are their short lifespan such that most pallets end up in landfills. Further, pallets have been known to carry bacteria such as E Coli, Salmonella, and Listeria. In addition to bacteria, pallets have been known to carry invasive species, insects, and other toxic chemicals. Many craft or repurposing ideas have kept pallets out of the landfill but unfortunately, most pallets used in craft or repurposing projects could still have been used in the shipping industry. As a result, more pallets are produced because of the removal of pallets for craft or repurposing projects, and more pallets ultimately end up in the landfill. Furthermore, using pallets in crafts may further facilitate the spread of harmful bacteria and dangerous chemicals. To help combat the spread of harmful bacteria and dangerous chemicals, wood alternative materials that are less porous are used to make pallets. One problem with wood alternatives is that some of the manufacturing processes used to make these pallets may be more harmful to the environment than just using wood. Furthermore, many of these pallets are made from a single material and only take advantage of the properties of that single material.
It is the object of this disclosure is to provide a pallet that uses a skeleton and an encapsulating material that takes advantage of the strength and durability of both the skeleton and the encapsulating material. With increased strength and durability, it aims to extend the life and strength of the pallet.
This disclosure relates generally to a pallet that includes a top deck having an encased first frame portion. The pallet also includes a support deck having an encased second frame portion.

Top deck 105, which may be either an open or a closed deck, may further include, as part of frame 150, one or more joists 120A-I and one or more beams 125A-C. The term open deck means that top deck 105 includes openings or apertures which extend through the deck from the outside of the deck to a middle portion of a pallet. The term closed deck means deck 105 contains no openings or apertures while the term deck refers to either an open deck or a closed deck inclusively. Joists 120A-I may extend in a first direction and beams 125A-C may extend in a second direction. The second direction may be substantially perpendicular to the first direction.
