【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing a food cooking bag according to one embodiment of the present invention. FIG. 2 is a front view showing a cooking example using a food cooking bag according to one embodiment of the present invention. 3 is a longitudinal sectional view showing a cooking example using the cooking bag, and FIG. 4 is a front view showing a state where the upper end after cooking using the cooking bag is sealed.
[0010]
The cooking bag 10 shown in FIG. 1 has a configuration in which three sides of a rectangular sheet laminated with a heat-resistant / pressure-resistant film or sheet (PET, unstretched nylon, stretched PP) or the like are sealed in a band shape and has an open side 10a. Is formed. Pressure valve elements 11 and 12 that form a pressure valve when the open side 10a is sealed are provided in advance on the open side 10a of the cooking bag body 10 by printing. One pressure valve element 11 is bent in a substantially bowl shape as a whole, and has a width of about 1 to 10 mm. The pressure resistance of the pressure valve element 11 can be set by the width and the length of the flange portion 11a.
[0011]
Printing shape of the other of the pressure valve element 12 is intended having a substantially inverted trapezoidal or wedge-shaped as a whole, and as shown in FIG. 2, the pressure valve adhered in its entirety substantially inverted trapezoidal or wedge-shaped reticulated The element 12a may be used. When configured in this manner, the pressure resistance can be set by the size of a substantially inverted trapezoidal shape or wedge shape, and it is possible to prevent the pressure inside the bag from rapidly decreasing due to the shape resistance even after the pressure valve is once opened.
[0012]
FIG. 3 shows still another pressure valve element 12b. For example, the pressure valve element 12b is formed by forming the strip-shaped printing portion 13 in a discontinuous state alternately. When configured in this manner, the pressure resistance (pressure at which the valve is opened) can be set by the interval and width of the strip-shaped printing unit 13.
[0013]
Set the breakdown voltage, changing the color of the printing composition e.g. 1.5 Kg ^/ cm 2, for each 2.0~4.0Kg / cm ^2. If comprised in this way, the cook can select the bag for cooking according to a cooking material easily with a color. Further, the color of the printing paint may be changed depending on the corresponding temperature and holding time. Any of the pressure valve element 11 and 12 also form wood fees such as a resin-based inks or pigment applied by printing.
[0014]
The pressure valve elements 11 and 12 thus configured are sealed by putting the food material 14 in the cooking bag 10 and then pressing and heating the films on both sides of the open side 10a with a predetermined width B (see FIG. 4). By this sealing process, the pressure valves 15 and 16 are formed in a state in which they are easily peeled off from the other sealing portions. The pressure valves 15 and 16 constituted by the pressure valve elements 11 and 12 have different opening pressures. That is, the pressure valve 15 is set to a pressure slightly lower than that of the pressure valve 16.
[0015]
As shown in FIG. 4, the foodstuff 14 is put, and the cooking bag 10 including the two types of pressure valves 15 and 16 is heated from the outside in an oven or the like. By heating, the food material 14 is cooked and the internal moisture is vaporized to become steam, and the internal pressure rises. Since the cooking bag 10 has a predetermined pressure resistance of 1.5 to 4.0 Kg / cm ² , it can be cooked in the same manner as cooking food with a pressure cooker.
[0016]
When the pressure inside the cooking bag 10 reaches a set pressure resistance of 1.5 to 4.0 Kg / cm ² , the pressure valve 15 is first peeled off at the lower limit of the set pressure. When the pressure valve 15 is opened, the pressure inside the cooking bag 10 is slightly reduced. However, heating from the outside continues and the pressure resistance of the pressure valve 15 keeps the inside at atmospheric pressure or higher. . Furthermore, when heating from the outside continues, water boils and evaporates and the internal pressure rises rapidly, the pressure valve 16 is peeled off and opened (see FIG. 5). Even if the pressure valve 16 is opened, the internal pressure during cooking is maintained at a pressure higher than the atmospheric pressure because of the flow path resistance of the pressure valve 16.
[0017]
Thus, even if it uses for cooking, the bursting of the cooking bag 10 can be prevented by opening the pressure valves 15 and 16.
[0018]
7 and 8 show another embodiment of the cooking bag according to the present invention. In this embodiment, a partition band 17 through which liquid passes is formed in the vicinity of the lower end of the food bag 20 made of a heat-resistant, pressure-resistant film or sheet, and a liquid reservoir 18 is formed below the partition band 17. .
[0019]
The partition band 17 has a small hole 17a through which a liquid passes at a predetermined location. As shown in FIGS. 7 and 8, for example, a fish 19 is enclosed in a cooking bag body 20 as an ingredient, and an upper end portion is sealed. The pressure valves 15 and 16 are formed.
[0020]
The cooking bag 20 thus prepared is cooked from the outside in an oven or the like with the pressure valves 15 and 16 facing upward. The liquid such as oil that has flowed out of the fish 19 by this cooking passes through the small hole 17a of the partition band 17 and accumulates in the liquid reservoir 18 at the lower end.
[0021]
After cooking, as shown in FIG. 8, the lower part 21 of the partition band 17 is sealed, and the lower parts 22 of the pressure valves 15 and 16 are sealed. In this way, the fish 19 can be cooked under a predetermined pressure, and the excess oil discharged by cooking can be removed and packaged.
[0022]
Next, the cooking method of the foodstuff using the bag 10 for cooking comprised as mentioned above is demonstrated. First, appropriate foodstuffs and cooking liquid are put into the food bag 10 made of a heat-resistant, pressure-resistant film or sheet that is open at one end. In this case, the cooking bag 10 having a pressure resistance suitable for the food to be cooked is selected. Also, the cooking liquid is appropriately selected depending on the ingredients and the cooking method.
[0023]
Next, the food bag 10 is sealed while forming the pressure valves 15 and 16 by sealing the open end 10a side of the food bag body 10 with a predetermined width along the printed portions of the pressure valve elements 11 and 12. By this sealing, as described above, the pressure valves 15 and 16 are formed and the cooking bag 10 is sealed.
[0024]
The food bag 10 in which the food is sealed is cooked from the outside in an oven or the like using far-infrared rays, and the food is cooked and sterilized. After cooking for a certain period of time, it is taken out from the oven and naturally cooled, and then sealed on the upper side of the food bag 10 where the pressure valves 15 and 16 are formed, inside the position where the pressure valves 15 and 16 are formed. . The part in which the pressure valves 15 and 16 are formed is cut off after sealing. In addition, it can cook without impairing the flavor of food by using far infrared rays.
[0025]
In this way, cooking of the food is completed without using a pressure cooker or the like. Further, unlike the prior art, there is no need for subdividing from a large pan or the like and no sterilizing operation, so that workability is easy and manpower can be saved.
[0026]
FIG. 9 is a front view showing a standing type embodiment of the cooking bag according to the present invention, and FIG. 10 is a side view thereof. The cooking bag 30 in this embodiment has a bottom 31 formed at the lower end and pressure valve elements 11 and 12 formed at the upper end. Therefore, when food is put into the cooking bag 30, the bottom 31 expands and can stand upright.
[0027]
When formed into a standing type, it can be set up in a standing state on a conveyor or the like during cooking. It is also convenient when displaying finished products after cooking. Furthermore, since the pressure valves 15 and 16 are always located at the upper part, the internal pressure can be discharged to the upper part.
[0028]
FIG. 11: is a front view which shows the other Example which shows the pressure valve 32 of the bag for cooking of this invention. The pressure valve 32 is composed of a vertical portion 32a, 32b and the corrugated portion 32c for connecting them. The lower end portion of the vertical portion 32a is disposed at a position lower than the upper end portion of the vertical portion 32b. Accordingly, the liquid is trapped in the corrugated portion 32c, and the water vapor can be discharged.
[0029]
Moreover, you may use the powdered egg shell as a pigment which forms a pressure valve element. The present invention is not limited to the above-described embodiments, and various other modifications can be made without departing from the gist of the present invention.
[0032]
【The invention's effect】
As described above, the food cooking bag according to the present invention is a food bag formed of a heat-resistant, pressure-resistant film or sheet and processed by sealing the periphery, and is sealed on one side to be sealed.
