Description

  The present invention relates to a range bag storage container for storing a packaging bag for a range that can contain food and the like and can be heated in a microwave oven or the like.

  Conventionally, when a packaging bag filled with contents such as retort food is heated with a microwave oven or the like, the pressure inside the packaging bag rises due to steam generated from the contents accompanying the heating, and the packaging bag bursts. The contents could be scattered. For this reason, in order to avoid an increase in pressure inside the packaging bag, there is a packaging bag provided with a mechanism for preventing part of the bag from breaking when the pressure rises and preventing the packaging bag from bursting.

  Such a packaging bag for a range is disclosed in Patent Document 1, for example. The packaging bag for the range disclosed in Patent Document 1 is provided with a gusset at the bottom of the packaging bag, and the bottom is seated in consideration of the convenience of the user, such as when filling the contents or displaying the product. Thus, a vertically placed type range bag having a substantially triangular cross section is disclosed.

  By the way, the vertical packaging type packaging bag having a substantially triangular cross section as described in Patent Document 1 is more complicated to manufacture than the flat packaging range bag that is sealed in all directions. Have difficulty. In addition, when using the range, there is a risk of falling down during the range if it is used in a vertically placed state, so it is used in a flatly placed state. However, such a vertically placed range bag, when used in a flat state, has a substantially triangular shape with its side (bottom) widened, and the steam vent that opens due to pressure increase during use of the range is the overall height. However, the stress due to the pressure increase cannot be effectively reflected on the steam escape portion, and the steam escape performance is reduced.

  In addition, since such a range bag has no handle portion, the entire packaging bag becomes hot after the range is raised, and there is a concern about burns when taking out from the range. Furthermore, since the sitting of the packaging bag itself is not sufficient, it is difficult to eat food directly from the packaging bag due to the risk of falling even if it is placed vertically after range up, and the upper part is cut off and opened. The advantage of vertical installation was not fully exploited.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to easily manufacture and the risk of overturning a packaging bag for a range that forms a steam escape with an increase in internal pressure due to the vapor pressure. There is no need to provide a range bag storage container that can be ranged vertically.

  In order to achieve this object, the present invention has the following features.

  The range bag storage container according to the present invention has a height side that does not cover the vapor discharge part of the packaging bag that forms a steam escape with an increase in internal pressure due to the vapor pressure, and can stand the packaging bag. .

  According to the present invention, a range packaging bag that can be easily manufactured and that forms a steam vent as the internal pressure rises due to the steam pressure can be ranged upright without any risk of falling.
