Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sesame bag containing raw sesame seeds or roasted sesame seeds.

BACKGROUND ART Microwave heating using a microwave oven or the like can heat food quickly and efficiently, and is widely used not only for home use but also for commercial and industrial purposes. On the other hand, sesame seeds are often roasted for their aroma, taste, etc., but they cannot be roasted by microwave irradiation alone, such as in a normal microwave oven, and the flavor etc. of sesame seeds cannot be sufficiently obtained. Furthermore, it would be convenient to be able to roast raw sesame seeds or re-roast roasted sesame seeds by using microwave irradiation, as conventional methods such as frying pans and pots are time-consuming.

The purpose of the present invention is to meet this demand and provide a bag containing sesame seeds that can quickly roast raw sesame seeds or roasted sesame seeds without requiring any effort by microwave irradiation.

Means for Solving the Problems The above object of the present invention is to provide a packaging bag containing sesame seeds, the packaging bag comprising a metal layer of aluminum or aluminum alloy, and an insulating layer covering the front and back surfaces of the metal layer. This is achieved by a bag containing sesame seeds characterized by being formed from a sheet made of.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a bag containing sesame seeds according to one embodiment of the present invention. As shown in FIG. 3, the sesame bag is made by depositing aluminum or an aluminum alloy on one side of an insulating layer 1 made of an insulating material such as polyethylene terephthalate (PET) or paper, or by depositing either of these. A metal layer 2 is formed by printing a paint containing metal powder, and the sheet 3 is formed by covering the surface of the metal layer 2 with another insulating layer 1' as described above.
The thickness of each of these layers is 50 Å to 500 Å for metal layer 2;
The thickness of the insulating layers 1, 1' is preferably 10 .mu.m to 40 .mu.m, more preferably the thickness of the metal layer 2 is 100 .ANG. to 400 .ANG., and the thickness of the insulating layers 1, 1' is 10 .mu.m to 30 .mu.m. metal layer 2
When the thickness is less than 50 Å, it is difficult to control metal deposition or printing in manufacturing, and when the metal layer 2 exceeds 500 Å, sparks are likely to occur during microwave irradiation. In addition, the insulating layers 1 and 1' are 10 μm thick.
If the thickness is less than 40 μm, the insulating material, such as polyethylene terephthalate, will easily melt, making it difficult to manufacture with paper. If the thickness exceeds 40 μm, the rigidity will be too high, making it difficult to manufacture the sesame bag of the present invention.

As shown in FIGS. 1 and 2, the bag containing sesame seeds has edges 5 and 5' of the sheet 3 bent into a cylindrical shape overlapping each other, and an open end 6 of the cylindrical shape.
It is a bag-shaped bag generally called a stick type, which is formed by heat-sealing or adhesion while containing 4 raw sesame seeds.

A sheet 3 that forms the sesame bag when the sesame bag containing raw sesame seeds 4 is placed in a microwave irradiation area of a microwave oven or the like and subjected to microwave irradiation.
Due to the Joule heat, raw sesame seeds 4 can be heated from the surface to a high temperature as if roasted over a fire. That is, by irradiating the sesame bag with microwaves for a predetermined period of time, raw sesame seeds can be quickly roasted without requiring much effort. The insulating layers 1 and 1' serve to prevent the molten metal generated from the metal layer 2 due to Joule heat from adhering to the sesame seeds 4, and also to prevent the molten metal from scattering into the microwave irradiation area. Edges 5 and 5' of the sheet 3 and the open end 6 during production of the filling bag
Facilitates heat fusion or adhesion.

In the embodiment, the shape of the bag containing sesame seeds is a stick type, but the shape is not limited to this, and various shapes capable of accommodating sesame seeds may be adopted. Further, in the above embodiment, raw sesame seeds are stored in the bag containing sesame seeds, but the bag is not limited to this, and roasted sesame seeds may be stored therein, and the roasted sesame seeds may be roasted again.

Effects of the invention As is clear from the above, according to the invention, since the sheet is formed of a metal layer of aluminum or aluminum alloy and an insulating layer covering the front and back surfaces of the metal layer, microwave irradiation can be performed. It is possible to provide a bag containing sesame seeds in which heat is generated in the metal layer, and as a result, raw sesame seeds or roasted sesame seeds can be quickly roasted without requiring any effort.
