Description

[Detailed explanation of the idea]

Purpose of invention

[Industrial application field]

The present invention relates to a popcorn package for microwave cooking, which allows popcorn to be prepared by heating it in a microwave oven.

[Conventional technology]

Since it is preferable to enjoy popcorn freshly made, popcorn is not only sold cooked at family restaurants and hamburger stands, but also packaged so that it can be cooked at home in a microwave oven is commercially available. Typically, such packages are simply a square-bottomed paper bag filled with popcorn mixed with seasonings and oil and sealed, and the popcorn may not be crispy enough or may be overcooked and lose its flavor. I was left unsatisfied with the results.

[Problem that the invention attempts to solve]

The purpose of this invention is to improve the packaging of popcorn that is cooked at home by heating it in a microwave oven, and to produce popcorn that can be cooked in a microwave oven so that popcorn that is always crispy and has a good flavor can be enjoyed immediately. The objective is to provide a package. Structure of the idea

[Means to resolve the issue]

As shown in FIG. 1, the popcorn package for cooking in a microwave oven of the present invention is made of a plastic material that can withstand heating in a microwave oven, and has a raised bottom at the center part 11 and a slope downward from the center toward the periphery. A popcorn material 5 containing necessary seasonings and fats and oils is placed in a container 1 which has a bottom flange 13 and an upper flange 14, and a folded plastic film 2 is placed on the lower flange 13 in an airtight manner. After sealing to reduce residual air, a lid 3 with a peel-off tab 31 is weakly sealed on the upper flange, and a heating element 4 that absorbs microwaves and generates heat is placed on the bottom of the container 1. It is attached so that it touches only at the part. The container 1 and the plastic film 2 are made of materials that can withstand heating in a microwave oven, typically polyester. Polyolefins such as polypropylene can also be used. The appropriate shape of the container is a circular drop-lid type, which can be easily obtained, for example, by vacuum forming. The lid 3 is to be peeled off when heating in a microwave oven, and is preferably made of a laminated aluminum foil material with high gas barrier properties to improve storage stability during distribution. The heating element 4 may be made of, for example, solid printing with conductive ink containing a large amount of carbon, or polyester film coated with aluminum vapor deposition. The above-mentioned package is preferably in the form of a container housed in a boat-shaped paper carton. In that case, the heating element 4 may be attached to this paper carton. You can remove the lid 3 and put it in the microwave, and after cooking, you can take it out without feeling hot by holding the carton part in your hand.

[Effect]

The popcorn package for microwave cooking of the present invention is placed in a microwave oven with the lid 3 removed as described above. When electricity is applied, the peripheral part 12 of the bottom of the container that is in contact with the heating element 4 is heated particularly strongly, and the temperature of the fat and oil increases, so that the popcorn that is in that part bursts. As the popcorn pops, the water in the popcorn kernels is released as water vapor, causing the volume inside the airtight container to expand. Folded and sealed film 2
It rises into a dome shape and absorbs this volumetric expansion. The popped popcorn kernels fall against the dome of the film and collect in the center of the container, i.e., at the bottom portion 11. Instead, the unpopped popcorn kernels sink to the periphery 12 at the bottom of the container and are heated and popped one after another. The inclination of the bottom of the container due to the formation of the raised bottom helps unpopulated grains to roll down and collect in the peripheral area where the temperature is high. For this reason, all grains can be blown efficiently with a small amount of fat and oil. By the time all the popcorn kernels have been popped, the film dome has expanded to its maximum extent and is filled with popped popcorn, as shown in FIG. You can judge whether the microwave heating time is enough by looking at how full it is. Then, you can take it out of the microwave, cut open the film, and enjoy your freshly made popcorn. Effects of the invention The popcorn package for microwave cooking of the invention enables popcorn to be easily cooked and enjoyed at home. There is no problem of overheating or underheating due to the size of the microwave capacity (wattage), and popcorn with good flavor can always be obtained with the appropriate degree of fluffing. Molded plastic containers have a nice appearance and make it easy to grab the popcorn, so you can serve it without having to empty it into another container.
