Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rice packaging bag that stores polished rice every 10 mm, for example.

[0002]

[Prior art]

 Heretofore, this type is well-known such as a single layer made of a polyethylene film, a laminate of polyethylene with a biaxially stretched nylon as an inner layer, or a laminate of unstretched nylon as an outer layer with polyethylene as an inner layer. . These rice packaging bags are further heat-sealed at the bottom of a tubular body having heat-sealed portions on both sides, and after storing a prescribed amount of polished rice in the rice packaging bag, heat the opening. It is to be sealed. A plurality of holes each having a diameter of about 1 mm are formed in the film on the front and back sides of the rice packaging bag so that air can be released when the polished rice is stored in the rice packaging bag.

[0003]

[Problems to be solved by the device]

 In the conventional technology, multiple holes were formed in the film on the front and back sides of the packaging bags for rice, so when the packaging bags for rice are stacked in a rice mill or a rice store, dust, etc. There is a risk that the rice may enter the rice packaging bag through the holes. It is an object of the present invention to solve the above problems and provide a hygienic rice packaging bag.

[0004]

[Means for Solving the Problems]

 The rice wrapping bag of the present invention is a rice wrapping bag made of a plastic film having seals on all sides, and the width of the seal is 4.5 to 5.5 mm. An unsealed portion with a width of 2.5 to 3.5 mm that connects the inside and the outside is formed.

[0005]

With the above configuration, the inside and outside can be communicated by the unsealed portion, so that when the rice packaging bags are stacked, there is no possibility that dust or the like will enter the rice packaging bag through the unsealed portion.

[0006]

【Example】

 Next, a first embodiment of the present invention will be described with reference to FIGS. The front and back plastic films 2 of the rice packaging bag 1 are made of nylon / polyethylene two-layer film, polyethylene / polyester two-layer film, polypropylene / polyethylene two-layer film, or nylon / polyethylene / polyester three-layer film. The heat-sealed portions 3 are formed in a cylindrical shape on both sides thereof to form a rolled product. The heat-sealed portion 3 has a width A of 4.5 to 5.5 mm, preferably 5 mm. An unsealed portion 4 is formed on the heat-sealed portion 3 at intervals of 50 to 100 mm, preferably 68 mm. The unsealed portion 4 is formed at the same time when the heat sealed portion 3 is formed, and has a width C of 2.5 to 3.5 mm, preferably 3 mm so that the inside and outside can communicate with each other. Has become. Further, as shown in FIG. 1, the bottom side of the plastic film 2 is closed by a heat seal portion 5. In the rice packaging bag 1 thus formed, after the rice 6 is put in through the opening 7, the opening 7 is heat-sealed and the heat-sealed portions 3, 5, 7A are formed on all sides.

Therefore, when the rice 6 is introduced through the opening 7, the air in the rice packaging bag 1 is exhausted from the opening 7 and the unsealed portion 4. Further, even if the rice packaging bag 1 is stacked and the rice packaging bag 1 is stacked with the rice packaging bag 1 heat-sealed, the unsealed portion 4 is in a horizontal direction. There is no possibility of penetrating into the rice packaging bag 1 through 4 Further, the width C of the unsealed portion 4 is set to 2.5 to 3.5 mm, preferably 3 mm, so that the rice grain does not leak to the outside through the unsealed portion 4 and the rice packaging bag 1 When the rice 6 is charged, air can be surely removed, and the strength of the rice packaging bag 1 can be exerted by setting the width A of the heat seal portion 3 to 4.5 to 5.5 mm. Further, the unsealed portion 4 is formed at the same time when the heat-sealed portion 5 is formed, so that the cost can be reduced.

3 and 4 show a second embodiment and a third embodiment of the present invention, in which the same parts as those of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, the outer side of the unsealed portion 4 is formed to be wide, and by doing so, the exhaust performance can be improved. Further, in the third embodiment, the outer side of the unsealed portion 4 is formed narrowly. By doing so, it is possible to surely prevent leakage of rice grains.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, when storing the polished rice by adjusting the strength (hardness) of the plastic film strainer, a substantially circular exhaust hole retains its shape. It is possible to make various modifications such as

[0010]

[Effect of device]

 According to the present invention, in a rice packaging bag made of a plastic film having sealing parts on all sides, the width of the sealing part is set to 4.5 to 5.5 mm, and the width for communicating the inside and the outside with the sealing part is 2. By forming the unsealed portion of 5 to 3.5 mm, it is possible to provide a hygienic rice packaging bag having excellent exhaust performance.
