Patent Description:
A microwave oven is often used to heat food, and the microwave oven heats the food by using dielectric-based heating as a technical basis. When the food is heated by using such a microwave oven, there is no element that may change a distribution and intensity of an electric field other than a dielectric change according to a temperature change of a heating body (food); and a local heating or non-heating phenomenon occurs in the heating body (food).

To prevent such a phenomenon, a turntable or stirrer is provided in the microwave oven, and a shape of the electric field is changed by heating a product via rotation of the turntable or stirrer.

However, because both the turntable and the stirrer use a method in which the product or a stirrer reflection plate concentrically rotates based on a vertical shaft, upward and downward changes in the electric field and an electric field change in a same radius from a rotation center are not large, and thus an overheating phenomenon occurs in upward and downward directions or in a specific concentric direction.

In detail, even when the turntable or stirrer rotating based on the rotation center is used, local overheating and non-heating phenomena in upward and downward directions of the heating body are unable to be prevented. Also, due to characteristics of the turntable rotating based on the rotation center, heating is performed in a concentric shape, and thus it is unable to prevent occurrence of relatively irregular heating according to a distance from the rotation center.

In particular, when the heating body is relatively thick in a specific direction in <NUM>-dimensions, it is difficult to prevent the local overheating and non-heating phenomena inside a thick portion due to above reasons.

Also, when the heating body has a cylindrical shape or cone shape, the local overheating and non-heating phenomena of a product occurs due to the above reasons, and the relatively irregular heating occurs according to the distance from the rotation center.

<CIT> discloses an expandable vessel that is operatively connected to a food product. When heated the vessel expands moving the food and thereby distributing non-uniformly distributed microwave energy more evenly throughout the food. In one embodiment, the vessel is a folded or coiled bag which retains steam and vapor evolved during the heating operation. The vapor expands the bag causing it to unfold i.e., straighten out thereby moving the food product from one location in the oven to another as microwave energy is applied. <CIT> discloses a rotating structure as defined in the preamble of claim <NUM>.

<CIT> discloses a packaging bag for use in a microwave oven, the bag having a steam releasing part in its edge and being stored in a box body. The box body comprises: a top side and a bottom side facing each other; and side faces continuous to the edges of the top side and the bottom side. A lid is formed on the top side in an openable manner. The packaging bag is double-folded, one side part having the steam releasing part by the double-fold faces the top side, the other side part faces the bottom side, and the parts are stored in the box body.

Also, in various embodiments of the present disclosure, it is to be understood that terms, such as "including" or "having", etc., are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof disclosed in the specification, and are not intended to preclude the possibility that one or more other features, numbers, steps, actions, components, parts, or combinations thereof may exist or may be added.

A rotating structure and a container using the rotating structure, according to an embodiment of the present disclosure, may be used for microwave oven cooking, and the container may be rotated according to expansion of a pouch, as the pouch is heated. However, the present disclosure is not limited thereto, and in the rotating structure and the container using the rotating structure, according to an embodiment of the present disclosure, the container may be rotated according to the expansion of the pouch, as the pouch is heated by a heating unit other than a microwave oven.

The container according to an embodiment of the present disclosure may be a rigid type or a flexible type, and is not limited to a specific material. A rigid container may be a cylindrical container formed of a material, such as paper, plastic, or the like, for accommodating content. A flexible container may be a flexible pouch container formed of a material, such as polyethylene terephthalate (PET) or the like, for accommodating content, and may have various shapes depending on shapes of the content.

Also, a container shape according to an embodiment of the present disclosure described below indicates a cylindrical shape, a polygonal container shape, a cone shape, a poly-pyramid shape, a truncated cone shape, or a truncated poly-pyramid shape, and may vary as long as the container shape has a narrow width while extending in one direction such as to be rotated while rolling.

Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

A rotating structure <NUM> according to an embodiment of the present disclosure includes a pouch <NUM> and a raw material provided inside the pouch <NUM>.

The pouch <NUM> is coupled to a container <NUM>, is wound around a circumference of the container <NUM> and rolls and rotates the container <NUM> according to expansion of the pouch <NUM>.

The container <NUM> may have a container shape and content is stored therein. The container <NUM> extends in one direction with a narrow width, such as a cylindrical shape or a cone shape, and has a shape capable of being rotated while rolling. The container <NUM> may have a cylindrical shape, a polygonal container shape, a cone shape, a poly-pyramid shape, a truncated cone shape, or a truncated poly-pyramid shape.

The container <NUM> may pack as content a product that extends in one direction and has a narrow width, such as gimbap, hotdog, or sausage, and the content stored in the container <NUM> may be food heated by a heating unit, such as a microwave oven. However, the content stored inside the container <NUM> is not limited to food and may vary as long as the content is capable of being heated by the heating unit.

Also, the container <NUM> may be a film or the like surrounding the exterior of the content of the product that extends in one direction and has a narrow width, such as gimbap, taco, hotdog, or sausage, and the container <NUM> may have the container shape by surrounding and packing the content of the product that extends in one direction and has a narrow width, such as gimbap, taco, hotdog, or sausage. For example, the container <NUM> may be a cylindrical flexible container formed of a material, such as paper, plastic, or the like, for surrounding gimbap, taco, hotdog, sausage, or the like.

The pouch <NUM> may be formed of a material capable of being expanded while accommodating a gas expanding in volume according to sublimation or evaporation of the raw material described below, and the pouch <NUM> may be formed of a polymer film material. However, a material of the pouch <NUM> is not limited to the polymer film material, and various materials may be used as long as the pouch <NUM> is able to accommodate the gas expanding in volume while being expanded in a desired direction and shape.

The pouch <NUM> is coupled to the container <NUM> while being wound around the circumference of the container <NUM>, and the pouch <NUM> may be coupled to various locations of the container <NUM> as long as the container <NUM> is rolled and rotated according to the expansion. The pouch <NUM> being coupled to the container <NUM> may indicate that the pouch <NUM> is directly attached to and coupled to the container <NUM>, or that the pouch <NUM> is indirectly coupled to the container <NUM> via another configuration.

Referring to <FIG>, the pouch <NUM> may be wound around the circumference at one side of the container <NUM> while forming a shape of a band, and may roll and rotate the container <NUM> as the pouch <NUM> is unwound by the expansion.

Referring to <FIG>, when the pouch <NUM> is expanded by the raw material, the pouch <NUM> may be gradually expanded along a long direction of the band. The long direction of the band indicates a length direction of the band, which is elongated when the pouch <NUM> has the shape of the band.

The pouch <NUM> is wound around the circumference of the container <NUM> having the container shape, and when the pouch <NUM> is gradually expanded along the long direction of the band, rotation momentum is generated at one side of the container <NUM>, and thus the container <NUM> is rotated and top and bottom portions of the container <NUM> are reversed.

Here, the raw material provided in the pouch <NUM> may be provided at one side end of the pouch <NUM> having the shape of band, and accordingly, the pouch <NUM> may start to be expanded from the one side end of the pouch <NUM>. When the rotation momentum is applied to the container <NUM> via the expansion of the pouch <NUM>, the container <NUM> may be effectively rotated when the rotation momentum is applied only at one side of the container <NUM>.

For example, when the pouch <NUM> having the shape of band starts to be simultaneously expanded in all areas, force is applied to various points along the circumference of the container <NUM>, and thus the container <NUM> is unable to be rotated in one direction. Accordingly, the raw material provided in the pouch <NUM> may be provided at one side end of the pouch <NUM> having the shape of band, and accordingly, the pouch <NUM> may start to be expanded from the one side end of the pouch <NUM>.

The raw material is provided inside the pouch <NUM>, and the raw material is able to expand the pouch <NUM> by forming a gas expanding in volume by being sublimated or evaporated while being heated.

The raw material may form a gas capable of being expanded in volume as a partial phase change occurs at a designated temperature, and may be a solvent for forming the gas capable of being expanded in volume by being sublimated at the designated temperature or a frozen material for forming the gas capable of being expanded in volume by being evaporated at the designated temperature. The raw material may be in a frozen solid phase according to a melting point and an evaporation point, or may be in a liquid phase. As such, various materials may be used as the raw material as long as the gas capable of being expanded in volume as the partial phase change occurs at the designated temperature is formed.

The raw material may be a solvent, such as water, alcohol, or the like, which is harmless to a human body, and a solute, such as salt, calcium, magnesium, or the like, may be added to the solvent to adjust degrees of the solvent absorbing an electromagnetic field and being heated.

The pouch <NUM> may be expanded by the gas formed as the raw material is sublimated or evaporated according to heating, and an expansion point of time of the pouch <NUM> may be adjusted via the raw material. In detail, the pouch <NUM> may be expanded at a designated temperature and at a designated time, according to the raw material provided inside the pouch <NUM>.

Here, the expansion point of time of the pouch <NUM> may be a point of time when the raw material starts a phase change and forms the gas, and the expansion point of time of the pouch <NUM> may be adjusted according to an amount or type of the raw material inside the pouch <NUM>.

According to an embodiment of the present disclosure, the content stored inside the container <NUM> may be various types of food, and a temperature and time for rotating the container <NUM> may vary depending on a type of the food. As such, the expansion point of time of the pouch <NUM> may be adjusted to adjust the temperature and time for rotating the container <NUM>, and the expansion point of time of the pouch may be adjusted by changing the amount or type of the raw material provided inside the pouch <NUM>.

In detail, a temperature of the expansion point of time of the pouch <NUM> may be changed by changing the type of raw material provided inside the pouch <NUM>. A sublimation temperature and evaporation temperature may be changed depending on a material of the raw material, and by changing the type of raw material, the sublimation temperature or evaporation temperature of the raw material is adjusted, thereby adjusting the expansion point of time of the pouch <NUM>.

Also, by changing the amount of raw material provided inside the pouch <NUM>, the time of expansion point of time of the pouch <NUM> may be adjusted. When the amount of raw material provided inside the pouch <NUM> is increased or decreased, the expansion point of time of the pouch <NUM> may be slowed down or quickened.

According to an embodiment of the present disclosure, the expansion point of time of the pouch <NUM> may be adjusted according to a shape of the raw material provided inside the pouch <NUM>. The raw material may be provided inside the pouch <NUM> in a frozen state, and the temperature and time of the expansion point of time may be changed according to the shape of the frozen raw material.

In detail, because the raw material that strongly emits heat according to a dielectric constant has a shape in which an electric field is focused on a surface, the temperature and time of the expansion point of time may be changed by adjusting a ratio of surface area to volume, via the shape of the raw material. When the ratio of surface area to volume is small in the raw material, the expansion point of time may be slowed down, and when the ratio of surface area to volume is large in the raw material, the expansion point of time may be quickened. When the raw material is of a thin film shape, the expansion point of time may be quickened as the ratio of surface area to volume is increased.

Also, the expansion point of time of the pouch <NUM> may be adjusted according to the dielectric constant of the raw material. The container <NUM> may be cooked by a microwave oven, and when the dielectric constant of the raw material is adjusted, a distribution and intensity of an electric field formed by the microwave oven may be adjusted, and accordingly, the expansion point of time of the pouch <NUM> may be adjusted.

The dielectric constant of the raw material may be adjusted via a solute that dissolves in a solvent, and by adjusting the dielectric constant of the raw material via the solute, such as salt, calcium, magnesium, or the like, a degree of the raw material emitting heat by absorbing the electric field may be adjusted.

As described above, the pouch <NUM> is capable of being expanded by the gas formed as the raw material is sublimated or evaporated, and the pouch <NUM> may rotate the container <NUM> according to the expansion. The pouch <NUM> may variously realize the rotation of the container <NUM> via the expansion, as will be described in detail below.

Referring to <FIG> and <FIG>, the pouch <NUM> may be wound around the circumference at one side of the container <NUM> having the container shape while forming the shape of band, and may roll and rotate the container <NUM> as the pouch <NUM> is unwound by the expansion.

Referring to <FIG>, when the pouch <NUM> is expanded by the raw material, the pouch <NUM> may be linearly expanded. The pouch <NUM> may be wound around the circumference of the container <NUM> having the container shape, and as shown in <FIG>, the container <NUM> may be located at a center hole of the pouch <NUM> and thus the pouch <NUM> may be attached and fixed to a part of the container <NUM>.

Referring to <FIG>, the pouch <NUM> may apply the rotation momentum at one side of the container <NUM> as one side of the pouch <NUM> linearly expands, and thus the container <NUM> may be rotated and the top and bottom portions of the container <NUM> may be reversed.

In detail, referring to <FIG>, when the pouch <NUM> is linearly expanded, force is transferred in a normal direction from a bottom side surface portion of the container <NUM>, and accordingly, the rotation momentum is generated in the container <NUM> having the container shape and the container <NUM> is rotated. (As shown in <FIG>, the top and bottom portions of the container <NUM> being reversed as the container <NUM> is rotated may be identified from a direction of an arrow shown inside the container <NUM> of <FIG> that is reversed as shown in <FIG>.

As such, by reversing the top and bottom portions of the container <NUM> according to the expansion of the pouch <NUM>, top and bottom portions of the content inside the container <NUM> may be uniformly heated.

Also, the container <NUM> may be continuously moved during cooking while adjusting an expansion speed of the pouch <NUM> according to the raw material inside the pouch <NUM>, and accordingly, the content inside the container <NUM> may be uniformly heated. In addition, the container <NUM> may be completely rotated at least one round by adjusting a length of the pouch <NUM> having the shape of band being wound around the circumference of the container <NUM>, and according to characteristics of the product, the container <NUM> may be rotated only half a around.

According to the invention there is a plurality of the pouches <NUM>, and the container <NUM> may be rotated as the plurality of pouches <NUM> are coupled to the container <NUM>.

When only one pouch <NUM> is provided, the container <NUM> may be rotated only in one direction, but depending on the content inside the container <NUM>, the container <NUM> may need to be rotated on one direction and then in another direction. In this regard, the plurality of pouches <NUM> may be provided, and as shown in <FIG>, two pouches <NUM> may be provided.

Referring to <FIG>, when the plurality of pouches <NUM> are coupled to the container <NUM>, the plurality of pouches <NUM> may be sequentially expanded, and accordingly, the container <NUM> may be rotated in one direction and then may be rotated in another direction again.

Here, the plurality of pouches <NUM> may have different expansions point of time depending on the raw materials inside the pouches <NUM>, and accordingly, the plurality of pouches <NUM> may rotate the container <NUM> by being sequentially expanded.

Referring to <FIG>, the pouch <NUM> may include a pin hole <NUM> that may be opened by gas pressure. The pouch <NUM> may maintain an expanded state, but the pouch <NUM> may return to its original state from the expanded state. The pin hole <NUM> externally discharges the gas inside the expanded pouch <NUM>, and the pin hole <NUM> externally discharges the gas inside the pouch <NUM> by being opened by designated gas pressure.

As shown in <FIG> and <FIG>, when two pouches <NUM> are coupled to the container <NUM>, after one pouch <NUM> is expanded and rotated the container <NUM> in one direction, the expansion of the one pouch <NUM> needs to be removed for the other pouch <NUM> to efficiently apply force to the container <NUM>.

When the pouch <NUM> includes the pin hole <NUM>, after the one pouch <NUM> is expanded, the expansion of the one pouch <NUM> may be removed before the other pouch <NUM> is expanded, and accordingly, the container <NUM> may be efficiently rotated in the other direction.

The pin hole <NUM> is completely opened by the gas pressure, thereby turning the inside of the pouch <NUM> back to a normal pressure state, and immediately removing the expansion of the pouch <NUM>. Alternatively, the pin hole <NUM> may slowly remove the expansion of the pouch <NUM> by adjusting residual internal pressure inside the pouch <NUM>.

In detail, the residual internal pressure inside the pouch <NUM> may be adjusted according to a size of the pin hole <NUM> opened by the gas pressure. When the size of the pin hole <NUM> opened by the gas pressure is large, the gas inside the expanded pouch <NUM> is quickly externally discharged, and thus the expansion of the pouch <NUM> may be quickly removed.

When the size of the pin hole <NUM> opened by the gas pressure is small, the gas inside the expanded pouch <NUM> is slowly externally discharged, and thus the expansion of the pouch <NUM> may be slowly removed.

The gas inside the pouch <NUM> may be externally discharged through the pin hole <NUM>, but according to an embodiment of the disclosure, the gas inside the pouch <NUM> may move into the other pouch <NUM> via a connection portion <NUM>.

Referring to <FIG>, when the plurality of pouches <NUM> are provided, the connection portion <NUM> connects the pin hole <NUM> of one pouch <NUM> from among the plurality of pouches <NUM> to the pin hole <NUM> of the other pouch <NUM>, and the connection portion <NUM> may be a path through which the gas inside the pouches <NUM> moves.

When the pin holes <NUM> and the connection portion <NUM> are provided, after the one pouch <NUM> is expanded, the gas may be moved to the other pouch <NUM>, thereby expanding the other pouch <NUM> and removing the expansion of the one pouch <NUM>.

Also, by using the connection portion <NUM>, the one pouch <NUM> may be re-expanded by moving the gas to the one pouch <NUM> again. The rotating structure <NUM> according to an embodiment of the present disclosure may variously realize rotation directions of the container <NUM> by expanding, reducing in volume, and re-expanding the pouch <NUM> by using the pin holes <NUM> and the connection portion <NUM>.

For example, the container <NUM> may be rotated in one direction according to expansion of the one pouch <NUM>, and then may be rotated in another direction as the gas of the one pouch <NUM> is moved to the other pouch <NUM> via the connection portion <NUM>. Then, the container <NUM> may be rotated in the one direction again as the gas in the other pouch <NUM> is moved to the one pouch <NUM> via the connection portion <NUM> again.

As such, the rotating structure <NUM> according to an embodiment of the present disclosure may variously realize rotation of the container <NUM> by expanding, reducing in volume, and re-expanding the pouch <NUM> by using the pin holes <NUM> and the connection portion <NUM>.

Here, when the plurality of pouches <NUM> are provided, the expansion points of time of the pouches <NUM> may be differently adjusted according to the raw materials inside the plurality of pouches <NUM>, and accordingly, a method by which the container <NUM> is rotated by be changed.

A container using a rotating structure, according to an embodiment of the present disclosure, relates to a container to which the rotating structure <NUM> described above is coupled, and because the rotating structure <NUM> has been described above, detailed descriptions thereof are omitted. A configuration and characteristics of the rotating structure <NUM> according to an embodiment of the present disclosure are all applicable to a container using a rotating structure, according to an embodiment of the disclosure.

The container <NUM> may pack the content of a product that extends on one direction and has a narrow width, such as gimbap, taco, hotdog, or sausage, and the content stored in the container <NUM> may be food heated by a heating unit, such as a microwave oven. However, the content stored inside the container <NUM> is not limited to food and may vary as long as the content is a heated by capable of being heated by the heating unit.

Also, the container <NUM> may be a film or the like surrounding the exterior of the content of the product that extends in one direction and has a narrow width, such as gimbap, taco, hotdog, or sausage, and the container <NUM> may have the container shape by the content of the product that extends in one direction and has a narrow width, such as gimbap, taco, hotdog, or sausage.

The container <NUM> may be rotated by the expansion of the pouch <NUM> being wound around the circumference of the container <NUM> while having the shape of band, and when the pouch <NUM> is expanded, the pouch <NUM> may be gradually expanded along the long direction of the band to rotate the container <NUM>. The long direction of the band indicates a length direction of the band, which is elongated when the pouch <NUM> has the shape of the band.

The raw material provided inside the pouch <NUM> having the shape of band may be provided at one side end of the pouch <NUM>, and accordingly, the expansion of the pouch <NUM> may start from one side end of the pouch <NUM>.

The pin hole <NUM> capable of being opened by the gas pressure may be provided in the pouch <NUM>, and the residual internal pressure inside the pouch <NUM> may be adjusted according to the size of the pin hole <NUM>.

When the plurality of pouches <NUM> are provided, the expansion points of time of the pouches <NUM> are differently formed depending on the raw materials in the pouches <NUM>, and accordingly, the container <NUM> may be rotated in one direction or another direction. Here, a direction in which one of the plurality of pouches <NUM> rotates the container <NUM> may be opposite to a direction in which another one of the plurality of pouches <NUM> rotates the container <NUM>.

Also, when the plurality of pouches <NUM> are provided, the pin hole <NUM> of the one pouch <NUM> is connected to the pin hole <NUM> of the other pouch <NUM> via the connection portion <NUM>, and the one pouch <NUM> may repeat expansion, reduction in volume, and re-expansion, thereby realizing movement of the container <NUM>.

A rotating structure and a container using the rotating structure, according to an embodiment of the present disclosure, have following effects.

The rotating structure and the container using the rotating structure, according to an embodiment of the present disclosure, expand the pouch <NUM> by providing the raw material that is sublimated or evaporated via heating, inside the pouch <NUM>. The container <NUM> according to an embodiment of the present disclosure is rotatable according to expansion of the pouch <NUM>, and the container <NUM> may be reversed upside down as the container <NUM> is rotated via the pouch <NUM>.

By reversing the container <NUM> upside down according to the expansion of the pouch <NUM>, content inside the container <NUM> may be reversed upside down, and accordingly, top and bottom portions of the content inside the container <NUM> may be uniformly heated.

The rotating structure and the container using the rotating structure, according to an embodiment of the present disclosure, adjust internal pressure for opening the pin hole <NUM> provided in the pouch <NUM> while adjusting a point of time when the pouch <NUM> is expanded via the raw material provided inside the pouch <NUM>, thereby realizing rotation of the container <NUM> according to a designed order and time, and accordingly, rotation suitable for cooking of a specific product may be realized.
