Description of the Related Art A ventilation bag is used as a bag for storing cooked items in a microwave oven or the like in order to release gas generated in the bag during heating. Therefore, it is necessary to shut off the ventilation, so they are housed in separate bags and double-packed. Alternatively, a storage bag may be provided with a vent valve or the like that operates to release gas by the internal pressure of the bag during cooking. However, in each case, a separate process is required after the completion of the bag-making process of the storage bag, which is not cost-effective and hinders mass production.

The non-welded remaining portion of the nonwoven fabric is formed in the air hole of the non-welded portion formed by not having the inner end facing the bag, and the outer end of the air hole is not conducted to the outside air. In addition to the arrangement, an opening means for communicating the outer end of the ventilation hole with the outside air is provided.

14が突出している。DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to illustrated embodiments. The embodiment shown in FIGS. 1 and 2 is a bag S for storing food for a microwave oven, in which the edges of polypropylene films 11 and 12 are heat-sealed to form bags. Heat-sealed part 13 by seal,
14 are protruding.

It is. That is, the non-woven fabric 2 is melted by the heat sealing with the non-woven fabric 2 interposed therebetween, and is melted and integrally welded to the non-woven fabrics 11, 12.
The non-welded portion not subjected to heat sealing becomes a hole state and becomes a vent hole portion 3 without dissolving the nonwoven fabric 2 therebetween.
As shown in FIG. 2, the non-welded non-woven fabric 20 remains between the films 11 and 12.

ールを回避する非溶着部とすることができるのである。The inner end of the vent hole 3 is open toward the inside of the bag, while the outer end 30 is further closed by a heat-fitting portion 15 formed on the outer portion by heat sealing. The width of the air hole 3 is about 2 mm, and the air hole 3 is bent in the middle to form a Z-shape. By forming the grooves so that they are not pressed against each other, a non-welded portion that avoids heat sealing can be obtained.

で電子レンジにかければよい。With such a bag, the ventilation hole 3 is buried in the heat-fitting portion 14, so that the ventilation with the outside air is blocked, and the stored food is sealed and kept in an appropriate storage state. It becomes. Then, when cooking in a microwave oven, the heat-deposited portion is broken along the cut 40 from the guide cut 41. As a result, as shown in FIG. 3, the outer end 30 of the ventilation hole 3 is opened and opened, and the outside air and the inside of the bag are ventilated through the ventilation hole 3. Good.

が、袋の内圧が急激に高まると、図2のように、通気孔
部3が開いて直接ガスが抜けることもある。Therefore, when gas is generated in the bag and the pressure in the bag is increased, the nonwoven fabric 2 slightly protruding into the bag is discharged to the outside air through the vent hole 3. At this time, even if there is no non-woven fabric 2 slightly protruding in the bag, the nonwoven fabric 2 is released from the vent 3 facing the inside of the bag.
Is released through the continuous pores of the non-welded non-woven fabric 20, but if the internal pressure of the bag increases rapidly, the vent 3 may be opened and gas may directly escape as shown in FIG.

内への侵入を防止できるのである。As described above, according to this embodiment, the ventilation can be normally shut off, the storage and storage can be performed well, and the gas can be vented at the time of cooking. It can be easily formed. In addition, when the state where the vent 3 is opened is left,
Even if germs try to invade from the air hole 3, the non-fused nonwoven fabric 20 is engaged with the germs and prevents further advance, so that it is possible to prevent invasion into the bag.

入防止のためには屈曲形状が望ましい。The present invention is not limited to this embodiment. For example, the shape and the number of the ventilation holes are not limited, and may be a complicated shape or a straight line as shown in FIG. However, a bent shape is desirable for preventing invasion of various bacteria.

向性を有するフイルムを用いてもよい。Further, the opening means for conducting the outer end of the vent hole to the outside air is appropriate. For example, when the outer end of the vent hole is heat-sealed as in this embodiment, the heat seal portion is broken. Is simple, but only the portion where the ventilation hole is arranged as shown in FIG. 5 may be broken. FIG.
As described above, a configuration may be adopted in which a cut tape 5 for guiding breakage is provided in the film and the tape tip 51 projects. Further, as shown in FIG. 6, when the outer end 30 of the ventilation hole 3 is arranged so as to be opened in another closed chamber 6, the closed chamber 6 is opened by breaking or the like, so that the outer end of the ventilation hole 3 is opened. 30 communicates with the outside air. Further, a film having a cutting direction that can be easily cut straight and may be used.
