Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container for storing microwave-cooked foods such as unfoamed popcorn.

[Conventional technology and its problems]

Popcorn is a sweet made from burst corn and seasoned with butter and salt, and has been popular as a snack since ancient times.

By the way, popcorn is more delicious when eaten immediately after cooking (immediately after the corn kernels are popped), so popcorn raw materials are mixed with corn oil and flavoring (seasonings such as salt) in an unfoamed state. Products have been developed that are sold in containers and are prepared by consumers before they eat them.

For example, as shown in FIG. 11, popcorn raw material A is stored in a disposable pan 30 made of a fire-resistant material such as metal foil along with corn oil, flavor, etc., and when popcorn raw material A foams, the popcorn raw material A is poured upward. There is a product covered with a synthetic resin film 40 that can bulge.

When cooking such a product, the popcorn raw material A is foamed within the synthetic resin film 40 by heating the product in a heater such as a furnace. The popcorn thus obtained is very flavorful and is therefore highly appreciated by consumers.

However, when such a product is placed in a heater such as an oven for cooking, the product must be continuously shaken. The reason for this is that when the product is left in a heater such as a furnace, the popcorn ingredient A in the bottom layer burns, while the popcorn ingredient A in the top layer becomes almost unfoamed and uncooked. This is because foamed popcorn cannot be obtained.

Therefore, in order to solve this inconvenience during cooking, as an improved product of the above-mentioned products that are cooked in a heating device such as a stove, we are developing a product that is cooked using a microwave oven. A product has been developed in which the popcorn material is stored in a plastic tray and covered with a synthetic resin film while ensuring a space above which the popcorn raw material can foam. When cooking in a microwave oven, the popcorn ingredients are irradiated relatively uniformly with microwaves without the troublesome work of continuously shaking the product, resulting in almost uniform foaming throughout the product. This is because you can get popcorn. Furthermore, since the bottom of the product is not exposed to fire directly, there is no need to use an expensive fire-resistant material to form the bottom.

However, even products that are cooked using a microwave oven are not without their problems.

For example, when cooking the product by placing it directly on a rotating plate (reflector plate) of a microwave oven, there is no space above and below the bottom of the product, that is, the bottom of the paper tray, for heat to dissipate. There is a problem that the bottom of the tray is easily burnt. Furthermore, although the popcorn raw material is irradiated relatively uniformly with ultrahigh-frequency waves, if we look closely, the bottom layer of the popcorn raw material tends to be relatively difficult to be irradiated with ultrahigh-frequency waves evenly, and there is a risk that it will not foam sufficiently. There is also.

The object of the present invention is to provide a food storage container for cooking in a microwave oven to solve such problems.

[Means for solving problems]

The food storage container for microwave cooking of the present invention, which was devised to achieve the above object, stores food for microwave cooking in a paper tray, and the upper part of the tray is covered with a synthetic resin film. In the food storage container for cooking, the bottom of the tray has a double-bottom structure with upper and lower layers, and the lower bottom is machined with appropriately shaped punching lines and folding lines. It is characterized in that the legs for floating the container can be assembled by shearing a part of the lower bottom along the bending line and bending the sheared part along the bending line. .

[Effect]

When cooking a food storage container for microwave cooking with such a configuration in a microwave oven, the container can be placed in a floating state on the rotating plate of the microwave oven, so that ultra high frequency waves can be used for cooking. The light is also reflected from below the container and irradiated onto the food to be cooked in a microwave oven, making it possible to realize efficient heating of the food. Furthermore, since a space is formed below the bottom of the container for heat to dissipate, it is possible to avoid a situation where the bottom of the container burns.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on drawings showing embodiments thereof.

FIG. 1 is a perspective view (viewed from the bottom side) of the microwave food storage container of the present invention in use, and FIG. 2 is a longitudinal sectional view thereof. In addition, FIG. 3 is a plan view showing the lower bottom (state before use) of the bottom of the food storage container for microwave cooking.

In the figure, reference numeral 10 indicates a tray made of paper (made of water-resistant and oil-proof paper), and the bottom of the tray 10 has a double bottom structure consisting of an upper bottom 11 and a lower bottom 12. In the tray 10, popcorn raw material A is stored together with corn oil, flavor, etc.

Further, the upper part of the tray 10 is covered with a synthetic resin film 20, and a space sufficient for the popcorn raw material A to foam is secured between the tray 10 and the synthetic resin film 20. There is.

Now, on the lower bottom 12 of the tray 10, there is a punched line B1 having a shape in which a pair of multiple hooked lines are integrally connected in a straight line (a straight line having a circular detour in the center), and four straight line shaped punched lines _B1 . A folding line C ₁ ...C ₁ is formed (see Fig. 3). Note that the folding lines C _{1 .} . . C ₁ may be perforations, or may be folds formed by pressing and deforming the paper to about half the thickness. and,
Legs D _{1 for floating the container by shearing a portion of the lower bottom 12 along the punching line B 1 and} folding the sheared portion along _{the folding line C 1 .} , D ₁ (see Figures 1 and 2) are ready to be assembled.

In addition, the semicircular recess created by shearing the center circular detour part of the punching line B ₁ is designed to hook fingers when assembling the legs D ₁ and D ₁ . It is something.

When cooking such _a container using a microwave oven, as shown in _FIG . Therefore, the extremely high frequency waves are reflected from below and irradiated onto the popcorn raw material A, as shown by the double-dashed line arrow, making it possible to achieve uniform heating and foaming. , flavorful popcorn A' can be obtained. Furthermore, since a space is formed below the tray 10 for heat to dissipate, the bottom of the tray 10 will not be scorched.

In addition to the above-mentioned shapes, various shapes of the punching lines and folding lines formed on the lower bottom 12 for assembling the legs for floating the container are conceivable.

For example, a punch line as shown in FIG.
B ₂ and folding line C ₂ ... If C ₂ has been processed,
Legs D ₂ and D ₂ as shown in FIG. 6 can be assembled.

In addition, a punch line as shown in FIG. 7 is provided on the lower bottom 12.
If B ₃ , B ₃ , B ₃ ' and folding lines C ₃ , C ₃ have been processed, legs D ₃ , D ₃ as shown in FIG. 8 can be assembled. Note that D ₃ ′ is a fixing member for both leg portions D ₃ , D ₃ , which is obtained by punching out the lower sole 12 along punch line B ₃ ′.

Furthermore, punch lines as shown in FIG. 9 are formed on the lower bottom 12.
If B ₄ , B ₄ , B ₄ and the folding lines C ₄ . . . C ₄ have been processed, legs D ₄ , D ₄ as shown in FIG. 10 can be assembled.

Although not shown in FIGS. 5 to 10, as explained in FIGS. 1 to 3, a portion that will become a semicircular recess on which the finger should be hooked is formed on the punching line. Needless to say, keeping it in place will be convenient when assembling the legs.

In addition, the bottom of the tray 10, that is, the upper bottom 11 and the lower bottom 12, may be made by folding a single sheet of paper to form a double structure, or by overlapping two sheets of paper to form a double structure. Either is fine.

Furthermore, although the above explanation uses as an example a container that stores unfoamed popcorn, this book also covers containers that store foods that are cooked in the microwave immediately before eating, such as stick-shaped fries. Needless to say, the idea can be applied.

[Effect of idea]

As detailed above, when the food storage container for microwave cooking of the present invention is used for cooking in a microwave oven, the stored items can be efficiently cooked, and the bottom of the container is not burnt. can be avoided.
