Problems solved by technology

[0023] However, care must be taken to avoid scalding when taking it out of the microwave oven. In order to eat it in this state, it needs to be transferred to another container, and even if it is taken home, there is the same inconvenience in use.
[0024] It is troublesome to move the food into the container, and the used container needs to be washed, and there is a problem that the amount of garbage increases when the container is disposable tableware

no. 1 approach

[0074] figure 1 , 2 shows this embodiment.

[0075] The packaging bag according to the present embodiment is used by sealing the peripheral portion, and the front side of the packaging bag is composed of one resin film, and the back side is composed of one resin sheet. The above-mentioned resin film and resin sheet are composed of the following material: the package formed by sealing the content containing moisture between the resin film and the resin sheet by heating the resin sheet on the back side with a microwave oven. When compacted, the resin sheet on the back side is deformed under the heat and pressure of the water vapor generated from the content to make the resin sheet on the back side into a concave shape, and the concave shape is still fully or partially maintained after the heating is completed.

[0076] The above-mentioned resin sheet may be a resin laminated sheet in which a resin film is adhered to at least the back surface. As will be described later, there...

[0089] image 3 , 4 shows this embodiment. image 3 An example of a package filled with contents in the packaging bag of the present embodiment is shown.

[0090] The packaging bag of this embodiment is a packaging bag used by sealing the peripheral portion, and the surface side of the packaging bag is as follows: image 3 As shown in (C), it consists of two resin films 2 and 3, and the back side consists of one resin sheet 1. The inner resin film 3 of the two resin films is bonded to the resin sheet 1, and the resin films 2, 3 and the resin sheet 1 are made of the following materials: Sheet 1 is a package body formed by sealing the content containing moisture between the above two resin films with the bottom surface heated in a microwave oven. The above-mentioned resin sheet 1 on the back side has a concave shape, and maintains the concave shape in whole or in part after the heating is completed.

[0097] Figure 5 , 6 shows this embodiment. Figure 5 An example of a package filled with contents in the packaging bag of the present embodiment is shown.

[0098] This embodiment is an application of the second embodiment.

[0099] In this embodiment, the adhesive layer between the resin sheet 1 and the resin film 3 of the second embodiment is a weakly adhesive adhesive layer. In this way, after the heating by the microwave oven is completed, the resin sheet 1 and the resin films 2 and 3 containing the contents 10 can be separated. Furthermore, the contents 10 accommodated in the resin films 2 and 3 can be taken out, moved to the container of the resin sheet 1, and eaten.

[0100] The packaging bag of this embodiment is in the same form as the packaging bag of the second embodiment in which the contents are accommodated in the resin films 2 and 3, so even if there is a small hole in the resin sheet 1, the packaging bag can be kept. sealed state.

Abstract

The objective of the present invention is to provide a new resin packaging bag with which heat sterilization is possible after vacuum packaging, the contents of which can be cooked in a microwave oven without being transferred to a vessel, and with which the package itself can be used as a vessel. This resin packaging bag for microwave ovens is a packaging bag in which the peripheral part serves as a seal, and is characterized in that: the front side of the packaging bag comprises one resin film (2) and the reverse side comprises one resin sheet (1); and the resin film (2) and resin sheet (1) comprise materials that, when a package formed by sealing moisture-containing content between the resin film (2) and the resin sheet (1) is heated in a microwave with the reverse side resin sheet (1) serving as the bottom surface, are deformed by the heat and pressure of the steam generated from the content such that the reverse side resin sheet (1) forms a recessed shape, and said recessed shape is completely or partially maintained, even after heating has been completed.

Description

technical field [0001] The present invention relates to packaging bags for packaging food and the like. Background technique [0002] As heating and cooking utensils for food, except conventional cooking utensils such as pans and frying pans, microwave ovens are becoming a widely used fixed configuration in families not only as heating utensils but also as cooking utensils. [0003] Therefore, along with the popularization of heat sterilization and freezing technology, it becomes common to eat precooked or semi-precooked retort bag food, frozen food, refrigerated (zero fresh-keeping) food and eat it in this state easily with microwave oven etc. Refer to Patent Document 1). [0004] In addition, in recent years, the number of households with less than two members has increased, and the demand for food for 1 to 2 people has continued to increase. In particular, the number of elderly people is increasing, the baby boom generation is gradually retiring, and the number of famil...
