Summary of the Invention
Problems to be Solved by the Invention
[0004] Conventional sand clocks are not only difficult to carry around because they are made of a single glass material, but also many of them have decorative frames made of wood, metal, etc., and are not suitable for use in humid places. In addition, since they are only designed to be placed on a horizontal surface, they cannot be taken outside and used.
Means for Solving the Problems
[0005] To solve this problem, according to the invention of claim 1, since the glass sand clock body is covered with acrylic, there is no risk of the glass sand clock body cracking and pieces flying around, and it is easy to carry around. In addition, since it is covered with acrylic, the sand clock body becomes completely waterproof and can be used in water. The square bar shape makes it easy to wipe off water droplets and dirt. And since a wire or rubber band is attached to the small body, it is easy to use it in the sauna by hanging the body in the air through the rubber band on the arm, or to attach it to a bag as a key holder and take it outside.
Advantages of the Invention
[0006] As described above, the present invention can be used not only as an hourglass but also as a key holder. In addition, since it is covered with acrylic, it can be easily wiped even if it gets wet.
