Benefits of technology

[0011]The cooling utensil of the present invention can be produced by assembling the parts. Even if, the water is fully filled in the elastic tube and freeze in the freezer, the utensil of the present invention will not be crack or distortion because the elastic tube will be expanded as expanding the volume of freezing ice. As the ice is melting, the ice floats over the melted water to keep contacting the upper part of the utensil. Therefore, the serving food on the upper part of the utensil will be kept cooling.
[0012]The parts have simple configurations to easily assemble together. Thus, it will reduce the manufacturing cost. It is also possible to design various shapes and select various materials. The cooling utensil of the present invention is provided a safety valve for preventing explosion, in case of unaware heating. The cooling utensil of the present invention is also provided a thermometer. Thus, the cooling is felt by visual, so that the serving food is felt fresh and tasty to stimulate the appetizer. The cooling utensil of the present invention is also provided a cover for maintaining the cooling for a longer time.
[0013]It is also possible to fill a coolant in the elastic tube for efficiently prolong the cooling time for the food, which is required cooling condition to serve or store.

Problems solved by technology

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.
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.
Therefore, it is hard to achieve the purpose of maintaining the food cooling fresh and testy during the eating.
However, this kind of conventional utensil usually has a big gap between the drawer and utensil body.
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.

first embodiment

[0062]As seen in FIG. 1 to FIG. 4, the cooling utensil according to the present invention is comprised of that an upper part (2), a lower part (3), an elastic plate (4), a plug bolt (5), a sealing ring (6) and a fastening bolt (7). The upper part (2) is assembled with the lower part (3) by the fastening bolt (7) forming a water inlet. The upper part (2) has formed a dome shape with series of grooves (23) from top to edge in the radial directions to drain the condensed water being generated due to the temperature difference. Then, the food served on the upper part of the utensil will not allow absorbing the condensed water, thus the food maintains fresh and tasty at the cool temperature. At a summit of the dome shape, a thermometer (24) is attached to display the serving temperature.

[0063]Further, a center post (26) having female thread is integrally formed underneath the dome shape of the upper part (2) to thread the fastening bolt (7). A water inlet (33) is connected to a water cha...

second embodiment

[0093]As seen in FIG. 5 to FIG. 6, the cooling utensil according to the present invention comprises that: an upper part (2a), a lower part (3a) and an elastic plate (4a). A set of springs (8) is mounted between the elastic plate (4a) and a lower part (3a) for supporting the upper plate (2a). A fastening bolt (7a) and a sealing ring (6a) is used to assemble the upper part (2a), the lower part (3a) and the elastic plate (4a) to be a final product.

[0094]The basic configuration of the upper part (2a), lower part (3a) and the elastic plate (4a) are same as that of the first embodiment of the present invention, except the shape.

[0095]The upper part (2a) forms a rectangular-shaped plate having a plurality of the square sections, which is divided by a series of ordinate and abscissa grooves (23) for draining the condensed water. A set of supporting posts (26) is integrally installed under the upper part (2a) at four corners. The center of the supporting post (26) forms a water channel (26a)...

fourth embodiment

[0106]The cooling utensil (1c) according to the present invention comprises that: an upper part (2c), a lower part (3c) and an elastic plate (4c). The lower part (3c), which is for supporting the elastic plate (4c), is used as a base for supporting the utensil.

[0107]The upper part (2c), which is for serving foods, forms a hemispherical shape at the center. A cavity is formed under the upper part (2c) for filling the water. An annular frame (29) having a hat-shape is slightly inclined outward for fixing the cooling plate (21). The upper part (2c) forms a cylindrical-shaped container with downward opening having a mail thread (21a) on outer wall. The lower part forms a cylindrical-shaped container without a top and having a female thread (35) on the inner wall for mating to the mail thread (21a) of the upper part. An elastic plate (4c) forming a disk-shape and annular sealing ring (42) are installed to fit under a rim of the mail thread (21a) of the upper part (2c).

Abstract

The present invention relates to a cooling utensil, which is a proof of freezing-crack and distortion. More particularly, an internal cavity of the utensil is fully filled the water to freeze in the freezer for cooling the serving food, such as a law fish, fruit, cold noodle or beer to feel fresh and tasty. For using the cooling bowl, the cooling cavity is filled the water or coolant for freezing. The cooling bowl is using for serving food. The cooling cavity is formed between the upper part and the lower part. The lower part is used a base to support the upper part. The upper part has same shape and size of the lower part for placing over the lower part. The elastic plate having flexibility and elastically restoring force is attached to the lower part, the upper part for assembling. Further, the cooling bowl having a cooling cavity is filled the water or coolant and freeze to use serving food. The lower part has built a dual wall to form a vacuum gap between the inner wall and the outer wall for insulation, so that the outer wall has no condensed water gained. The elastic tube (4k) having elastically restoring force is inserted through the water inlet (33). the plug bolt (5k) mounted at the mouth of the water inlet (33), for sealing the water filled cavity.

Description

TECHNICAL FIELD[0001]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[0002]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 ...
