Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit under 35 U.S.C. §119 of TW Application No. 101123944, filed Jul. 3, 2012, the contents of which are incorporated by reference as if fully set forth.

FIELD OF THE INVENTION

The present invention is tableware, specifically a foldable plate.

BACKGROUND OF THE INVENTION

The Food Pyramid was first proposed by the United States Department of Agriculture (USDA) in 1992. The food pyramid was basically guidelines for a balanced and healthy diet. It combines nutritious foods with balanced healthy diet guidelines. It systematically categorizes daily food intake. The closer to the bottom of the pyramid, the more frequently the food should be consumed. The closer to the top of the pyramid, the less frequently the food should be consumed. This simple and creative design leaves an impression and helps make everyone who has seen the food pyramid able to understand. FIG. 1 shows the food pyramid promoted by Department of Health of Taiwan.
In 2011, the U.S. Department of Agriculture published another guideline called “MyPlate” to replace the food pyramid because the United States Department of Agriculture felt the food pyramid was probably too complex for the average family to practice easily and efficiently in daily life in present society.
The so-called MyPlate is the new balanced and healthy diet guideline; it is much simpler and more straightforward than the food pyramid. As revealed in FIG. 2, the guideline divides a plate into four regions (lattice). Each region is associated with a specific color and labeled with the corresponding text annotations at the bottom of the region such that: the red Fruits region represents fruits, the green Vegetables region represents vegetables, the orange Grains region represents grains and the purple Protein region represents proteins. Outside the plate is a blue Dairy region representing dairy products. Such a simple plate, “MyPlate”, replaces the food pyramid which had been used for 19 years. It was subsequently promoted around the world to become the new dietary guideline.
MyPlate is a straightforward design, the elements constitute a healthy meal and can be seen at a glance. For any person, it is easy to choose a nutritious meal with the new food plate whether he/she is shopping outside, buying lunch or eating at a buffet as long as the five regions of the plate are filled.
For modern busy people, especially families who often dine out, MyPlate is a great idea. However, it would be difficult to dine out carrying MyPlate around every day, especially because the size of MyPlate is not considered small. Another thing is that there are many disposable serving dishes. Although they are designed with lattices, they are not designed to follow the healthy diet nutrition principles.
Therefore, in order to overcome the shortcomings in the prior art, it is necessary to provide an innovative idea. After careful testing and research with perseverance, the applicant finally conceived the idea “Smart Plate” to overcome the mentioned shortcomings, and the following is a brief description of this invention.

SUMMARY OF THE INVENTION

In the light of the shortcomings of the conventional technologies, the present invention provides a folding plate, which can overcome the aforementioned drawbacks. The folding plate of the present invention may be produced using a variety of suitable substrate materials and formed with a variety of appropriately designed pressed lines, grooves, guide lines, positioning elements, and fixing elements to guide users to make it in a do-it-yourself (DW) manner. In a very short period of time, a plate with the concept of a healthy and balanced diet is made to serve food.
Such dishes can be made for male, female, old or young people to suit different demands. Different sub-grids are planned to contain all kinds of food in order to achieve a healthy diet. If we can replace the conventional sub-grid disposable plates with this invention, it would provide a great benefit for modern people in the aspect of health and balanced nutrition. Such a plate also allows people who usually dine out to custom-make/tailor-make the plate with sub-grids in accordance with their needs.
According to a first aspect of the present invention, a foldable plate is proposed which includes a substrate having a center portion and a plurality of edges. A plurality of ridges is formed by folding the substrate, and the ridges intersect with each other. A plurality of protecting edges is formed by folding a plurality of edges of the substrate towards the central portion of the substrate. The plurality of containing regions is thereby formed between the plurality of ridges and the plurality of edges.
According to the second aspect of the present invention, a foldable plate is proposed which includes a substrate, a plurality of containing regions and having a foldable structure formed directly from the substrate.
The third aspect of the present invention proposes a foldable plate-making method that includes providing a substrate, folding the substrate to form a plurality of ridges such that the plurality of ridges intersect with each other, and folding a plurality of edges of the substrate towards the center portion of the substrate to form a plurality of protecting edges so that a plurality of containing regions is formed among the plurality of ridges and the plurality of protecting edges.
