Description

RELATED APPLICATION

This application claims priority to provisional patent application U.S. Ser. No. 62/680,246 filed on Jun. 4, 2018, the entire contents of which is herein incorporated by reference. The disclosure of prior U.S. Ser. No. 15/987,681 now U.S. Pat. No. 10,123,641 is hereby incorporated by reference.

BACKGROUND

China uses 20 million trees each year to supply their demand for disposable, single-use chopsticks. At approximately 4,000 chopsticks per tree, that is roughly 80 billion chopsticks per year. Greenpeace has dedicated a campaign to the chopstick problem, blaming it for the destruction of 1.18 million square meters of forest every year.
As set forth by Erica Lee in DES 40A Winter 2018 University of California, Davis—Department of Design, via Design Life-Cycle website reproduced in part below: Disposable wooden chopsticks, a staple utensil at Asian restaurants, are often tossed in the trash without second thought. These seemingly harmless wooden sticks, treated with multiple chemicals and thus making them not biodegradable, take up a great deal of space in landfills. These disposable wooden chopsticks generate tons of waste in the duration of their life cycle, from their inception, to their transportation, and to the end of their lives. Although alternative methods to reuse wooden chopsticks have been devised, they still produce wastes and it will be a while before these methods are implemented on a larger scale.
In addition to the carbon dioxide emissions from the machinery used, the chemical processing of the wooden chopsticks produces hazardous chemical waste. Generally, the wooden chopsticks are bathed in a solution of different chemical compounds, but the most common ingredient used is sulfur dioxide (Nuwer).
Transportation of disposable wooden chopsticks from factory to restaurants around and across the Pacific has its economic benefits, but the thousands of miles traveled has its effect on the environment. Chinese made disposable chopsticks are both consumed in China and exported to Japan, Korea, and the United States (Newer).
Arguably, the transportation of the chopsticks produces the largest amount of waste in the whole life cycle of a pair of disposable chopsticks due to the sheer millions of tons of exhaust from cargo ships and trucks.
Once used, disposable wooden chopsticks are thrown away and into landfills they go. Since wooden chopsticks are bleached and treated with the chemical bath, they are not compostable. When people throw away the wooden chopsticks, they end up in landfills and eventually these wooden chopsticks will biodegrade over a few decades. The larger issue is that China goes through roughly forty-five billion pairs of disposable wooden chopsticks a year while the international market goes through over eighteen billion pairs of the wooden chopsticks and over ninety percent of these wooden chopsticks end up in landfills around the world (Gardener).
One solution to not using wooden chopsticks is for people to carry their own, reusable chopsticks. But the problem is that reusable chopsticks are often made out of metal or plastic, and by nature are long and inconvenient to carry around. If people are to bring reusable chopsticks everywhere, they will want somewhere clean to put the reusable chopsticks. That means keeping the reusable chopsticks in a case that's even bigger and bulkier than the reusable chopsticks in their current form.
Therefore, there exists a need for convenient reusable chopsticks that are easy to carry, store, and easy to clean.

SUMMARY

Reusable chopsticks that are foldable into a compact configuration for storage and easily transportable in a storage case. The chopsticks each comprise a rigid external structure and at least one flexible internal member that permits the chopstick to be foldable to a compact configuration for storage. In a folded configuration, the reusable chopsticks have a significantly reduced length of approximately one-half to one-fourth or less of their extended length when in use. The external structure of the chopstick is preferably formed of multiple rigid segments connected by the flexible internal member(s) in the extended configuration during use as chopsticks. A storage case is provided to store the chopsticks in the folded configuration in a compact form.
The chopsticks of the present invention are collapsible chopsticks that self assemble. The chopsticks are in an extended configuration preferably when at least two of the segments are coupled together with the flexible internal member to form the rigid external structure of the chopstick. In a preferred embodiment, the coupling of the segments to one another via reciprocal interdigitating ends, such as with male and female configured ends, form a rigid structure once assembled. The flexible internal member being under tension within the chopstick to maintain the segments coupled together. The elastic nature of flexible internal member, returning from a stretched state in the folded configuration to a less-stretched state in the extended configuration, functions to essentially automatically extend and reconfigure the chopstick to the extended configuration.
The chopstick is in a folded configuration preferably when at least two of the segments are uncoupled from one another and moved apart along the flexible internal member by stretching the flexible internal member and folding the flexible internal member between at least two segments.
The present invention provides a convenient reusable chopsticks that are easy to carry and store.
These and other objects of the present invention will be apparent from review of the following specification and the accompanying drawings.
