AI Technical Summary
Existing chopstick storage solutions face a dilemma in balancing hygiene and reducing waste, often requiring the sacrifice of one for the other, particularly in the context of environmental pollution and resource efficiency.
A design where a pair of chopsticks has a hollow tip that fits into the handle of the other, allowing the tips to be stored inside and the handles to be used as normal chopsticks, eliminating the need for separate storage containers.
This design enables hygienic storage and transportation of chopsticks without generating excess waste, allowing for easy transition to using them as regular chopsticks by exposing only the handles.

Abstract
Description
[Technical field]
[0001] The present invention provides chopsticks that also function as a chopstick case. [Background technology]
[0002] Chopsticks made of wood, bamboo, plastic, or metal are often stored and transported in chopstick bags or cases to prevent dust, droplets, and viruses from adhering to them when used in restaurants or for bento boxes or side dishes. However, the world is now in an era where waste must be reduced in order to prevent environmental pollution, such as the problem of marine plastic waste, and to make effective use of resources.
[0003] In order to reduce the amount of waste generated by chopstick wrappers, there are efforts to change chopstick wrappers from plastic film to paper, and to use thinner films and papers. Summary of the Invention [Problem to be solved by the invention]
[0004] In terms of chopsticks and their wrappers / cases, it is difficult to ensure hygiene while also being considerate of the natural environment and reducing waste, and the current problem is that one must sacrifice the other. The present invention has been made to solve this problem. [Means for solving the problem]
[0005] The chopsticks are made of wood, bamboo, plastic or metal, and have a cavity (4) in the handle (2) into which the tip (3) of the other chopstick is placed. The pair of chopsticks are staggered so that the tip (4) fits into each other's cavity (4), so that when stored, only the handle (2) of the chopsticks is exposed to the outside, and the tip (3) that comes into contact with food in the human mouth when used is placed inside the cavity (4). Chopsticks for eating comprise the above structure. Effect of the Invention
[0006] As no chopstick bags or cases are used, no extra waste is produced, and chopsticks can be stored and transported without the tips coming into contact with human hands or splashes. When the chopsticks are to be used, the tips are exposed and the chopsticks can be used as normal chopsticks. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] Hereinafter, an embodiment of the present invention will be described. (a) Two sticks of the same shape (1) are combined together to be used as chopsticks. (b) The handle (2) of the stick (1) has a cavity (4) large enough to insert the tip (3) of the stick (1). The present invention has the above-mentioned structure. When stored, the present invention has the tips of the sticks (3) inserted alternately into the handles (2) of the sticks. When using, the handles (2) are held with both hands and pulled to the left and right, exposing the tips (3) of the sticks inserted into the hollows (4), forming two sticks (1). These handles (2) are held between the thumb, index finger, middle finger, and ring finger in the same way as regular chopsticks are held, and used as chopsticks for picking up food.

Claims
[Claim 1] These chopsticks are made of two identical sticks (1) made of wood, bamboo, plastic or metal, and the tip (3) of the other stick fits into a cavity (4) provided in the handle (2), so that the tips (3) can be stored alternately in the cavity (4) in a sealed state that does not come into contact with human hands or splashes, and the chopsticks are structured so that the tips are exposed and can be used as normal chopsticks only when they are used as chopsticks.
