DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cake container and its manufacturing method.
2. Description of the Prior Art
Conventionally, cake containers for containing cake such as pound cake have a disk-shaped bottom and a circumferential wall extending upward at the periphery of the bottom. When a cake is baked with such a container, the cake batter, containing wheat flour, sugar, cooking oil, etc., is poured into the container, and subsequently, the container is placed on a hot plate. When the hot plate is heated, the cake batter is heated through the bottom of the container, the oil added to the batter is dispersed, the batter swells in accordance with the configuration of the wall, and a cake having a desirable shape is baked.
However, in the conventional containers described above, since the batter is heated through the bottom of the container, the oil added to the batter may not properly disperse due to the poor heat conductivity, which deteriorates the taste of the cake. Furthermore, since the time for heating the cake batter needs to be longer so as to disperse the oil added to the batter, the efficiency of the baking process is lowered.
Accordingly, it is a primary object of the present invention to facilitate the dispersion of oil added to the batter during heating and to improve the taste of the cake.
Another object of the invention is to improve the efficiency of the baking process by shortening the time for heating the batter and to provide a container that efficiently heats the batter with uniformity and is not likely to lose shape.
An additional object of the invention is to efficiently manufacture a container having a through hole formed at the bottom without losing its shape during manufacture.
SUMMARY OF THE INVENTION
To solve the problems described above, in the present invention, a through hole is formed for forming and maintaining the cake batter, which is heated to swell in a predetermined shape. Therefore, when a hot plate, on which the batter filled is placed, is heated, heat is better transmitted to the batter by way of the through hole, and the batter is efficiently heated. This efficient heating facilitates dispersion of the oil added to the batter so that the taste of the cake is improved.
The through hole is preferably formed to be sized more than a given extent in its opening area relative to the entire bottom of the container. In this case, since the through hole that enables the cake batter to be directly heated occupies a large portion of the entire bottom, heat transfer to the cake batter is easier.
The container consists of an annular circumferential wall by forming a through hole that extends over the entire bottom of the container. In this case, when the batter swells during heating, the entire circumferential wall, which is pushed by swelling batter, is brought into an equal expansion in the radial direction.
A flange projecting inward along the circumferential wall may be located at the lower edge of the circumferential wall of the container at its bottom. The through hole may be formed with a size that is identical to the inner periphery of the flange. In this case, the strength of the container is increased by the flange, and the container can be stored without losing its shape.
A plurality of through holes may be formed at the bottom of the container. In this case, a shape-holding force is applied to the container, and the entire cake batter is efficiently heated with uniformity by way of the plurality of through holes.
When a container is manufactured, a through hole is formed in the center of the material of the container, and then, the material is placed between thin plate-like clamp members and is placed between first and second molds. Subsequently, the second mold is fitted into a cavity. When the second mold is fitted into the cavity in the first mold, a plurality of clamp members are bent toward the second mold due to the opening of the cavity. Between the clamp members, which are placed between the outer sur
