Description

One body structure type base film sheet of the container for cooking food}

The present invention relates to a base film sheet of a food cooking container which can be cooked immediately as it is a container in which food is embedded. In particular, the base film sheet itself has a pressure control function without a separate pressure control structure. It relates to a structural base film sheet.

A food cooking container having such a structure is disclosed in detail in Korean Patent Laid-Open Publication No. 2000-50620, which has been filed by the present inventors. 1 shows an example of such a food cooking container, that is, the food cooking container 10 which can be eaten by simply heating the food without opening the package is made of a flexible material such as a plastic sheet. The upper sheet 12 and the lower sheet 13 having a structure in which a single sheet or two or more materials are laminated, and the end portions 14 are sealed after the food 15 is embedded therein. A pressure regulating structure 11 having a function of regulating pressure by steam generated from foods embedded during heating is installed.

In the conventional pressure regulating structure 11, as shown in FIG. 2, the opening 22 is formed in a part of the top sheet 12, and the pressure regulating sheet is made of a flexible sheet in a form of closing the hole thereon. The structure 21 is bonded by the adhesive agent 23.

In addition, in the pressure regulating structure configured as described above, the adhesive uncoated portion 24 is formed at the center of the pressure regulating sheet 21, and the adhesive uncoated portion 30 includes the opening 22. It has a larger area than study (22) and is usually non-circular (eg an isosceles triangle). Therefore, the food 15 does not contact the adhesive 23, but only the adhesive uncoated portion 30, thereby preventing the food 12 from being contaminated. Then, when the container 10 is heated, the moisture of the food 15 is evaporated to change into water vapor, and the internal pressure of the container 10 is increased, and when the internal pressure is above a certain pressure, the pressure is controlled through the opening 22. When the seat 21 starts to separate from the container 10, the inclined side is larger than the bottom of the isosceles triangle and starts to separate from the container 10, and when the internal pressure reaches a predetermined pressure, one of the pressure regulating valves 11 When the pressure inside the container begins to decrease and the pressure inside the container falls below a predetermined pressure, a part of the open pressure regulating sheet 21 is brought into close contact with the container 11 again.

The container for cooking food with such a structure not only enhances the packaging function but also functions as a cooking utensil, which not only increases the product value of the food that is stored, but also preserves the food for a long time, and is convenient and simple because it only needs to be heated. It has the advantage of cooking food.

However, a food cooking container having a pressure regulating structure having such a structure must have a circular or elliptical through hole on the sheet constituting the container, so that a full opening may fail in mass production. Since there are a lot of debris cut at the time, this may act as a large claim to the final product, and there is a possibility that the vacuum may fall into this part due to the weak pressure control structure when vacuuming the food into the system package. When the food is heated and opened in the pressure control structure during cooking, the impact is large, and in some cases, the container moves largely, and the packaged food may flow out into the opening, such that the pressure control function is not easy. I have it.

The present invention has been made to solve the above problems, and provides a new integral structure base film sheet having a pressure control function of part or all of the base film of the container itself without mounting a separate pressure control structure as in the prior art. The purpose is to.

The present invention is a container for cooking food, characterized in that to form a cut through the unperforated pressure in the container in a single layer or a flexible film sheet constituting the food cooking container as one method for achieving the above object. To start.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a method for achieving the above object, integral with the porous film sheet and the cut portion is formed or integrally of the food cooking container, characterized in that the base film sheet of the single layer or multilayer structure without the incision with adhesive. Disclosed is a structural base film sheet.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 illustrates an example of a base film sheet according to the present invention, that is, a porous film sheet 31 is laminated using a single layer or multilayer base film sheet 33 and an adhesive 32 having cutouts 24 formed thereon. As a structure, the food cooking container manufactured by using the base film sheet having such a structure as a part (lid) or the whole of the container is heated after sealing the food, and the water present in the food evaporates to vaporize. As the container expands due to diffusion, when the predetermined pressure is reached, the cutout portion 34 formed in the base film sheet 33 is expanded as shown in FIG. 4, whereby water vapor rises through the pinhole in the adhesive 32. This occurs, and then pressure control in the container is performed while releasing water vapor through the porous film sheet 31 to the outside of the container.

As the porous film sheet 31 in the above, a thermoplastic nonwoven fabric may be used, and the shape of the cutout portion 32 may be formed without limitation, such as an S-shape or an I-shape, and the number of cutouts may also be appropriately adjusted. It is desirable to determine within the range.

Figure 4 shows another example of the base film sheet according to the present invention, the upper surface using a porous film sheet 41 as the base film sheet and the lower surface using a thermoplastic film sheet 43 laminated in a single layer or multiple layers It is a structure bonded by the adhesive agent 42. In this case, as the container is heated, moisture present in the food is evaporated, and when the container is expanded by vapor diffusion, steam is released to the outside through the porous film 31 to control the pressure in the container. In response to water vapor generation, pressure adjustment can be performed with almost no impact.

Hereinafter, the present invention will be described in more detail with reference to Examples, and the scope of the present invention is not limited thereto.

EXAMPLE

A 0.15 mm thick nylon nonwoven fabric was used as the porous film sheet, and a 0.04 mm thick polypropylene film was formed as an S-shaped cutout as shown in FIG. . The base film sheet was sealed at 10 mm in width in three directions to form a food cooking container having a width of 120 mm and a length of 240 mm. At this time, the incision was positioned at the center of the container.

80 g of fish was put in the container, and the remaining portion was sealed with a width of 10 mm and sealed. Put it in the microwave and set the timer to 2 minutes 30 seconds to switch on. From about 1 minute and 40 seconds, the water content of the food material itself evaporated gradually, and the water vapor in the container diffused, and the expansion of the container was confirmed. After that, the incision expands and the adhesive layer starts to thin in the form as shown in FIG. 4, and after 2 minutes from the start of heating, the pressure in the container increases to about 1.5 kg / cm 2 and the temperature rises to 110 ° C. As the steam began to diverge outwards, the pressure control in the vessel was started, and the cooking was terminated after 30 seconds while maintaining at a set pressure of 1.3 kg / cm 2 and a temperature of 106 ° C. in the vessel.

Example 2

As a top film, a porous film sheet (55 seconds / 100 ml) made from a single or a plurality of tissue materials is used, and a laminate of 0.015 mm thick nylon film and 0.04 mm polyethylene film is used as the bottom film. Each was cut into a width of 130 mm and a length of 200 mm, and the corner portions in three directions were sealed with a width of 10 mm to prepare a food cooking container.

Two meat dumplings (70 g / piece) were put into the container, and the remaining one direction edge portion was sealed with a width of 10 mm and sealed in the form as shown in FIG. The vessel was placed in a microwave oven and the timer was set to 2 minutes to switch on. At about 1 minute and 05 seconds, the water content of the food material itself evaporated by heating, and the water vapor in the container diffused to confirm the expansion of the container.After 1 minute and 35 seconds from the start of heating, the pressure in the container was about If the temperature was maintained at 1.2 kg / cm 2 and the temperature was 104 ° C., the cooking was finished after 25 seconds.

As described above, when the integral structure type base film sheet according to the present invention is used as a container for food cooking, the processability and storage property are excellent, and the pressure can be controlled almost without impact due to the increase in pressure inside the container. It can be used to pass through the bay, to prevent the outflow of liquids or solids, and to prevent the incorporation of impurities.
