    TECHNICAL FIELD
  • The present invention relates to a utensil for maintaining cold temperature. More particularly, the utensil has a special built-in compartment to fill the water for cooling or freezing in the freezer. The utensil would not freeze-crack or distortion while the water in the utensil compartment is freezing in the refrigerator. Therefore, the food, such as a low fish (sashimi), fruits, cold noodle or beer on this utensil can be kept fresh and tasty as long as the utensil maintains the cool temperature for a quite long time.
  • BACKGROUND ART
  • A conventional utensil has an internal cavity to fully or partially fill the water for cooling or freezing. If the cavity is fully filled the water, it will cause the utensil broken due to the volume expansion while the water is freezing in the freezer. Depending on the material, the utensil will be cracked for the ceramic or glass, and will be distorted or burst for the metal plate or plastic product. As a result, the damaged utensil can not longer to be used.
  • Accordingly, the internal cavity of the utensil is not fully filled the water for an air pocket. If the water is freezing, the air pocket, which is formed on top of the ice, is caused an inferior heat transfer between the ice and the food on the utensil.
  • On the other hand, if the utensil is put upside down while the water is freezing in the freezer, the freezing utensil might be good heat transfer at the beginning of usage, but it will not go longer as the ice start melting to form the air pocket below the contacting surfaces. The cooling effect between the ice and the food on the utensil will be rapidly decreased. Therefore, it is hard to achieve the purpose of maintaining the food cooling fresh and testy during the eating.
  • Other conventional cooling utensil has a separated cooling unit, which has a form of a drawer for filling ice or dry-ice and inserting into underneath of the utensil to indirectly contacting the serving food. However, this kind of conventional utensil usually has a big gap between the drawer and utensil body. Due to the large gap, the cooling effect is rapidly vanished.
  • It is also inconvenient to handle the main body of the utensil and the separated cooling unit for separately preparing the ice or dry ice.
  • DISCLOSURE OF INVENTION Technical Problem
  • In order to solve the problems of the conventional utensils, the non-crack and distortion utensil of the present invention has developed. The purpose of the present invention is to provide a flexible tube or a compartment being made of an elastic plate with restoring capability. The compartment is enveloped by the upper part and the lower part of the utensil with a lid for filling the water.
  • It is demanded a new cooling utensil, which would not be cracked or distorted during the freeing process due to the volume expansion. Even if the ice inside of the utensil is melting, the low temperature must be maintained to keep the food in cool condition for a long time. It is also required a simple structure for easily manufacturing by using the various materials and assembling the product with lower cost. So, it must be possible to design the various styles of the utensils. It must have durability not to explode, even though the utensil is heated on the flame by a mistake.
  • Technical Solution
  • In order to achieve the aforementioned purpose, the cooling utensil of the present invention has a compartment to fill the water or coolant for freezing to serving. Such a compartment, which is made of an elastic plate having restoring capability, has formed a cavity between the upper part and lower part of the utensil. The outer surface of the upper part forms the various shapes of dishes or containers for directly contact the food, and the outer feature of the lower part forms a base of the utensils, such as a disk-shaped foundation, a standing legs or supporter. The upper part and lower part are brought together to be one body of the utensil by binding means, such as an assembling or welding.
  • The usage of the cooling utensil of the present invention is simple as follows: first, fill the water or coolant in the compartment, next, the utensil is placed in the freezer until the water is freezing. After completely freezing the water, the utensil is used to contain the food on it. The upper part, which is directly contacting the food, has assembled with the lower part to form a body.
