JP7350291B2 - Washed rice bags and rice packs filled with rice - Google Patents

Description

The present invention relates to a washed rice bag filled with rice and a washed rice pack.

Many rice washing bags have been developed as tools for facilitating rice washing (for example, Patent Documents 1 and 2). The bag for washing rice described in Patent Document 1 is configured to put rice into the bag through an opening, close the opening, and wash the rice.
Further, the rice washing bag described in Patent Document 2 has polyethylene sheets overlapped to close the outer periphery, and a zipper that divides the bag into two is formed near the center of the bag in the vertical direction so that the bag can be freely communicated. Then, a large number of through holes with a diameter smaller than a grain of rice are formed in the sheet on the bottom side of the bag, and the unrinsed rice is stored in the top side, and the zipper is closed. When using a washed rice bag, open the zipper and drop the rice stored in the top of the bag, which does not have holes, into the bottom of the bag, open the top of the bag, and fill the rice with water through the opening. It is washable. That is, this rice washing bag employs a structure in which a rice storage bag and a bag having holes are integrated via a fastener.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, embodiments of the rice-filled washed rice bag of the present invention will be described. Note that the dimensions of each part in the figures used in the following explanation are not necessarily the same as the actual ones, and can be changed as appropriate.

As shown in FIG. 1, a washed rice bag 1 containing rice according to an embodiment of the present invention has a rectangular bag portion 2 containing rice (not shown) and continuously sealing the outer periphery 2a. be.
The bag portion 2 is formed into a rectangular bag shape by folding one mesh sheet 3 into two layers.
The ends 2a of the bag portion 2 on three sides other than the folded end 2b are sealed by heat sealing.

The mesh size of the mesh sheet 3 may be smaller than a size that prevents rice (not shown) from leaking from the bag portion 2.
The warp density and weft density of the mesh sheet 3 may be, for example, both 60 or more and 130 or less/inch, and preferably 80 or more and 120 or less/inch.
The fineness of the mesh sheet 3 is not particularly limited, but for washing rice, it may be, for example, 15 dtex or more and 150 dtex or less, and more preferably 20 dtex or more and 60 dtex or less.

The material of the mesh sheet 3 is not particularly limited, but synthetic fibers having heat-fusible properties are preferred. As the synthetic fiber having thermal fusibility, for example, polyester-based, polyamide-based or polylactic acid-based fiber is preferable. Among these synthetic fibers, polyethylene terephthalate (PET) and biodegradable synthetic resins are preferred, and polylactic acid fibers are more preferred.

As the synthetic fiber of the mesh sheet 3, monofilament or multifilament is preferably used. Further, the synthetic fiber of the mesh sheet 3 may be a single fiber or a composite fiber. The synthetic fiber used in the present invention uses two components with different melting points, and a core-sheath type synthetic fiber in which the core component has a higher melting point of about 40 degrees or more than the sheath component is particularly preferred. Can be used. Specifically, in addition to core-sheath composite fibers in which the core is made of PET with a melting point of about 230°C or more and the sheath part is made of PET with a melting point of less than about 190°C, there are also A core-sheath type synthetic fiber made of a combination of polylactic acid and polylactic acid whose sheath portion has a melting point of about 130° C. is preferably used. However, the combination is not limited to the above, as long as it is a core-sheath type synthetic fiber that can be used for mesh-like woven or knitted fabrics.

It is preferable that 50% or more of the entire intertwined portion of the synthetic fibers of the mesh sheet 3 is thermally fused by setting processing (also referred to as heat treatment). If the intertwined portions of the synthetic fibers of the mesh sheet 3 are fused, it becomes possible to cut the mesh sheet 3 by hand without using tools such as scissors, and after washing the rice, the rice can be easily removed from the bag section 2. It can be taken out.

Although the bag portion 2 can be closed by sewing the end portion 2a that is open when the mesh sheet 3 is folded with a thread or the like, it is preferable that the bag portion 2 is closed by fusing. Although there is no particular restriction on the method of fusing the mesh sheet 3, it is preferable to use a heat fusing method, a high frequency fusing method, an ultrasonic fusing method, or the like.

The shape of the bag portion 2 is not particularly limited, and examples thereof include a circle shown in FIG. 2 and a trapezoid (not shown). In order to make it easier to take out the rice from the bag part 2, it is preferable that the bag part 2 does not have a corner 8 of 90 degrees or less as shown in FIG. For example, when a rectangular shape is adopted as the shape of the bag portion 2, the corner 8 may be made obtuse by cutting off a right angle into a triangle as shown in FIG. 3, or the corner 8 may be rounded as shown in FIG.

The type of rice accommodated in the rice-filled washed rice bag 1 of the present invention is not particularly limited as long as it is raw rice before cooking, and includes white rice, brown rice, and the like.

The amount of rice is not particularly limited, but from the viewpoint of ease of measurement, it is preferable that a fixed amount of 1 go or more is stored.
In addition, to prevent you from losing track of the amount of rice you put in the rice cooker when you put the rice in the rice cooker and fill it with water after washing the rice, mark the amount of rice on the mesh sheet 3 as shown in Figure 1. It is even better if 5 is added.

For the mark 5, a method can be adopted in which the quantity is printed on the mesh sheet 3 using an edible synthetic coloring agent. Alternatively, as shown in FIG. 3 or 4, by forming one or more notches in the sealed portion of the outer periphery 2a of the mesh sheet 3 in a number corresponding to the amount of rice, without using an edible synthetic coloring agent. , it may also be a mark 5 indicating the amount of rice. Alternatively, the mark 5 may be formed by stamping.

As shown in FIG. 1, the washed rice bag 1 filled with rice is preferably housed in an exterior body 6 that houses and seals the washed rice bag 1 filled with rice to form a washed rice pack X before use.
When enclosing rice in the outer package 6 of the washed rice bag 1, it is preferable that the outer package 6 is filled with an inert gas to prevent the rice from deteriorating. Alternatively, the interior of the exterior body 6 may be evacuated.

Next, a method of using the washed rice bag 1 filled with rice will be explained.
The washed rice bag 1 filled with rice already contains a certain amount of rice, and the outer periphery 2a is sealed by fusion to prevent the rice from spilling during washing. Therefore, when washing rice, it is possible to immediately start washing the rice without making any preparations such as reducing the weight of the rice and storing the rice in the bag portion 2.

Specifically, the washed rice bag 1 filled with rice is taken out from the exterior body 6, and the washed rice bag 1 filled with rice is soaked in water or washed with water, and the entire bag portion 2 is lightly rubbed.
When washing rice, it is considered important to quickly and firmly cut the polishing liquid containing rice bran, especially the polishing liquid containing a large amount of rice bran, in order to make the rice taste delicious.

In this respect, since the rice-filled washed rice bag 1 uses the mesh sheet 3 made of synthetic fiber, the rice bran component is almost never trapped in the bag portion 2. In addition, the mesh sheet 3 has good water permeability, and the synthetic fibers do not absorb rice bran components or water containing rice bran. Furthermore, since the bag portion 2 of the present invention is formed of the synthetic fiber mesh sheet 3, the bag portion 2 drains water very well.

Therefore, water containing rice bran can be quickly and firmly shaken off during rice washing.
In addition, since it is possible to prevent rice bran or sharpening juice from accumulating in the bag portion 2 or from containing a large amount of polishing juice in the bag portion 2, it is possible to prevent rice from accumulating in the bag portion 2 or from containing a large amount of polishing juice. Almost all of the grinding juice will come out. Therefore, it is possible to avoid making a mistake in washing rice based on the degree of cloudiness of the polishing liquid.

Finish washing the rice by checking the water and judging how well the rice has been washed. The degree of polishing of the rice is done as appropriate depending on the variety and type of rice.
Immediately after washing the rice, shake the rice-filled washed rice bag 1 to thoroughly drain the water. Since the mesh sheet 3 has good water permeability and drainage, water adhering to the rice can be easily shaken off by holding the rice-filled washed rice bag 1 and shaking it lightly.

After draining, the bag part 2 is opened and the rice is put into a rice cooker or the like from the bag part 2. At this time, since the bag portion 2 is formed of the mesh sheet 3 of the present invention, it can be easily torn by hand. In addition, the rice-filled washed rice bag 1 of the present invention can drain water well, thereby preventing the rice from adhering to the mesh sheet 3 due to moisture and becoming difficult to fall off. Furthermore, since the mesh sheet 3 is made of synthetic fibers, the rice can be easily dropped from the bag portion 2 even if the rice has a slight amount of moisture.

Since the present invention has the above-described structure and functions, it has the effect that rice can be easily and skillfully washed like a professional chef.
Further, after washing the rice, the bag portion 2 can be easily opened by hand without using scissors or the like. Therefore, it is possible to quickly process the rice after washing without having to prepare scissors or disinfect them.

Moreover, the rice-filled washed rice bag 1 has the effect that when the rice contained therein is small, the rice can be easily washed with one hand.
In addition, the periphery is tightly closed by fusing when the rice is contained, and if the user closes the opening by himself or himself, rice may fall out of the bag 2 if the opening is not closed sufficiently or if the opening is closed incorrectly. You don't have to worry about spilling it. Therefore, unlike conventional rice-washing bags, it is possible to efficiently wash rice in a plurality of rice-filled rice-washed bags 1 at the same time in one container.

In addition, when you want to wash multiple rice-filled washed rice bags 1 at the same time in one container, such as when cooking rice outdoors, and want to divide the rice into several rice cookers and cook the rice, you can use rice-filled rice bags 1. This has the effect that rice can be easily divided into desired amounts for each rice cooker by counting the number of washed rice bags 1.

In addition, if you forgot the amount of rice in the rice cooker after washing it and putting it in the rice cooker, conventionally you had to put the washed rice in a measuring device and re-measure it. According to the washed rice bag 1 filled with rice, the amount of rice can be easily determined by counting the number of bag parts 2.

Further, when rice is transferred from the bag section 2 to the rice cooker, the rice is difficult to adhere to the bag section 2, so that the rice can be processed more efficiently after washing.
Due to these effects, it is possible to easily and skillfully prepare rice before cooking, and prepare the rice to be deliciously cooked.

Note that the synthetic fiber forming the mesh sheet 3 may contain polypropylene. When the mesh sheet 3 has polypropylene fibers, it becomes easier to adsorb the lipids in the rice produced by rice milling until the rice is washed, which has the effect of suppressing the addition of odor to the rice. play.

Furthermore, the mesh sheet 3 may include synthetic fibers having an irregular cross section that can cause small scratches on the rice. Synthetic fibers with irregular cross sections can make small scratches on the surface of the rice, allowing the rice to absorb water quickly. Therefore, by washing rice with the rice-filled washed rice bag 1 having this configuration, it is possible to quickly cook delicious rice.

Moreover, the mesh size of the mesh sheet 3 may be 500 μm or less. According to this configuration, impurities etc. that have adhered during rice milling can be discharged from the bag portion 2.
Moreover, the mesh size of the mesh sheet 3 may be 200 μm or less. According to this configuration, it is possible to prevent rice insects (such as the weevil or the Japanese grain weevil) from entering the bag portion 2.

Further, the rice-filled washed rice bag 1 may be made of biodegradable synthetic resin. According to this configuration, even if the washed rice bag 1 containing rice is disposed of after use, it is naturally decomposed, so that it is possible to reduce the burden on the environment.

Moreover, as shown in FIG. 3, an opening part 7 may be formed in the bag part 2 to facilitate opening. The unsealing portion 7 can be formed at a notch 7a and a breaking line 7b. Alternatively, since the mesh sheet 3 can be easily broken in a straight line, only the notch 7a may be required as shown in FIG. You can.

In addition, if the mesh sheet 3 is formed into the bag portion 2 by stacking two sheets and sealing the outer periphery, even if the mesh sheet 3 is folded into two sheets, Separated mesh sheets 3, 3 may be overlapped and the entire outer periphery may be continuously sealed.
