With reference to FIGS. 8-14, the effect | action of the package 1 is demonstrated.
As shown in FIG. 8, the package 1 includes an outer bag 10, a tray 100, and a content 200. The contents 200 are accommodated in the accommodating portion 120 of the tray 100. The content 200 indicates Shumai. The package 1 is heated using a microwave oven in a state where the bag outer seal portion 50 and the inner seal portion 60 are sealed. As the contents 200 are heated, the content 200 generates water vapor. For this reason, the internal pressure of the accommodating part 120 of the tray 100 rises.

As shown in FIGS. 9 and 10, the inner seal portion 60 peels before the bag outer seal portion 50 as the internal pressure of the housing portion 120 increases.
After the inner seal portion 60 is peeled off, the water vapor is discharged into the bag inner space 21 through the opening 151 of the tray 100. Even after the inner seal portion 60 is peeled off, the bag outer seal portion 50 is sealed. That is, the tray 100 and the contents 200 are sealed by the outer bag 10. For this reason, the internal pressure of the package 1 rises even after the inner seal portion 60 is peeled off.

  As shown in FIGS. 11 and 12, as an example, the second vaporization promoting portion 54 </ b> B peels off as the internal pressure of the package 1 increases. For this reason, the water vapor | steam generate | occur | produced in the bag interior space 21 is discharged | emitted outside through the peeled 2nd vaporization promotion part 54B. Note that, as an example, the state where the second steaming promoting part 54B is peeled off is shown, but at least one of the first steaming promoting part 54A, the third steaming promoting part 54C, and the continuous portion 51D (see FIG. 2). By peeling off, the water vapor generated in the bag inner space 21 is discharged to the outside.

  After the heating of the packaging body 1, the packaging body 1 is electronic when the user grips at least one of the first gripping seal portion 51, the second gripping seal portion 52, and the third gripping seal portion 53. Removed from the range.

As shown in FIG. 13, after the package 1 is taken out from the microwave oven, the opening part 30 is separated from the bag body part 20 via the notch 71 and the guide wire 72.
As shown in FIG. 14, after the opening portion 30 is separated from the bag main body portion 20, the tray 100 is taken out from the bag main body portion 20 with the handle main body 171 being gripped by the user.

The package 1 has the following effects.
(1) The package 1 has a tray 100. The tray 100 has an opening 151. The opening 151 is closed by the outer bag 10 because the inner seal portion 60 is formed. The tray 100 of the package 1 is accommodated in the bag interior space 21 of the outer bag 10. That is, the exterior bag 10 has a role of closing the opening 151 and a role of wrapping the tray 100. For this reason, the packaging body 1 is reduced in the number of materials constituting the packaging body 1 as compared with a structure in which a lid that closes the opening 151 and a bag that wraps the tray 100 are individually formed. Thus, the package 1 can suppress the contents 200 from leaking from the tray 100 and can reduce the number of materials constituting the package 1.

  (2) The package 1 has a bag outer seal portion 50. The bag outer seal portion 50 includes a first grip seal portion 51, a second grip seal portion 52, a third grip seal portion 53, and a steaming seal portion 54. The steaming seal portion 54 has a lower sealing strength than the first grip seal portion 51, the second grip seal portion 52, and the third grip seal portion 53. For this reason, the packaging body 1 can discharge | evaporate a vapor | steam from the vapor-permeable seal part 54 outside, when the internal pressure of the bag inner space 21 rises by being heated.

  (3) The package 1 has a tray 100. The tray 100 has a tray seal part 160 and a storage part 120. The tray seal portion 160 is formed on the entire circumference of the accommodating portion 120. For this reason, the inner seal portion 60 has a larger sealing area than the configuration in which the tray seal portion 160 is formed in a part of the accommodating portion 120. For this reason, the effect which suppresses that the package 1 leaks the content 200 from the tray 100 is heightened.

  (4) The tray 100 accommodates the contents 200. The contents 200 generate water vapor when heated. The internal pressure of the tray 100 increases due to the generation of water vapor. The bag inner seal portion 22 is peeled off from the tray seal portion 160 due to an increase in the internal pressure of the tray 100. The bag inner seal portion 22 is less likely to peel from the tray seal portion 160 as the seal strength of the inner seal portion 60 increases. On the other hand, the package 1 may generate a sound when the bag inner seal portion 22 peels from the tray seal portion 160. This sound tends to increase as the internal pressure of the tray 100 increases when the bag inner seal portion 22 peels from the tray seal portion 160.

  The inner seal portion 60 of the package 1 has a lower sealing strength than the bag outer seal portion 50. For this reason, the sound when the bag inner seal portion 22 is peeled off from the tray seal portion 160 is reduced as compared with the configuration in which the inner seal portion 60 is assumed to have a higher sealing strength than the bag outer seal portion 50. . For this reason, the user is less likely to feel discomfort due to the sound generated when the bag inner seal portion 22 peels from the tray seal portion 160.

  (5) When the water vapor in the bag inner space 21 is discharged to the outside through the vapor sealing part 54, the vapor sealing part 54 may be at a high temperature. The package 1 has an explanation display unit 80. The explanation display unit 80 includes a first explanation display unit 81. The first explanation display unit 81 displays a part of the outer bag 10 where the first grip seal part 51, the second grip seal part 52, and the third grip seal part 53 are formed. The first explanation display unit 81 displays that the first grip seal unit 51, the second grip seal unit 52, and the third grip seal unit 53 are gripped. For this reason, the package 1 is prevented from being erroneously gripped by the user with the high-temperature vapor-permeable seal portion 54.

  (6) The package 1 has a vapor-permeable seal portion 54. The steaming seal part 54 includes a first steaming promotion part 54A, a second steaming promotion part 54B, and a third steaming promotion part 54C. 54A of 1st steaming promotion parts, the 2nd steaming promotion part 54B, and the 3rd steaming promotion part 54C are smaller than the 1st grip seal part 51, the 2nd grip seal part 52, and the 3rd grip seal part 53 It has a seal width. For this reason, as for the package 1, the seal | sticker of 54 A of 3rd steaming promotion parts 54C among the steaming sealing parts 54 becomes easy to peel. For this reason, the packaging body 1 can discharge | emit vapor | steam more appropriately when the internal pressure of the bag inner space 21 rises.

  (7) The package 1 has a vapor sealing part 54. The steaming seal part 54 includes a first steaming promotion part 54A, a second steaming promotion part 54B, and a third steaming promotion part 54C. For this reason, as for the package 1, compared with the package of the structure where the steaming promotion part is one place, the steam is appropriately transmitted to the outside via the first steaming promotion part 54A to the third steaming promotion part 54C. Can be discharged.

  (8) The exterior bag 10 of the package 1 has a rectangular shape in plan view. The exterior bag 10 has a bag body 20 and an opening 30. The opening part 30 is formed continuously with the bag body part 20. The opening part 30 includes a second side edge 16 that is an edge of the long side of the exterior bag 10. The opening part 30 has a structure that can be separated from the bag body part 20. The unsealing part 30 opens the in-bag space 21 by being separated from the bag body part 20.

  In the package 1, the opening space 30 including the second side edge 16 of the outer bag 10 is separated from the bag body 20, so that the in-bag space 21 is opened. For this reason, the user pulls out the tray 100 from the bag inner space 21 in the direction in which the short sides of the outer bag 10, that is, the upper edge 17 and the lower edge 18 extend. For this reason, the package 1 has a configuration in which the opening portion 30 is formed to include the upper edge 17 or the lower edge 18, that is, the first side that is the long side of the outer bag 10 from the bag inner space 21. Compared to a configuration in which the edge 15 and the second side edge 16 are pulled out in the extending direction, the tray 100 is easily taken out from the bag inner space 21.

  (9) When the internal pressure of the bag inner space 21 rises, the mountain folded portion 41 of the edge of the package 1 is a place where the edges of the sheets forming the outer bag 10 are sealed with each other, that is, the second side edge 16. It is harder to tear than the upper edge 17 and the lower edge 18. The exterior bag 10 of the package 1 has a mountain folded portion 41. The mountain folded portion 41 is formed with a third grip seal portion 53. For this reason, the package 1 can grip a portion where steam does not escape when heated in a microwave oven or the like, that is, a portion that is difficult to reach a high temperature.

  (10) The exterior bag 10 of the package 1 has a valley folded portion 42. The valley fold portion 42 is formed in the front direction ZA1 of the exterior bag 10 relative to the mountain fold portion 41. For this reason, the package 1 can make the dimension of the front-back direction ZA small.

  (11) The inner seal portion 60 of the package 1 has a lower sealing strength than the steaming seal portion 54. For this reason, the bag inner seal portion 22 is easily peeled off from the tray seal portion 160 as compared with the configuration in which the inner seal portion 60 is assumed to have a higher sealing strength than the vapor-permeable seal portion 54. For this reason, as for the package 1, after the inner seal part 60 peels, the vapor-permeable seal part 54 peels. For this reason, when a user takes out tray 100 from exterior bag 10, it can control that inner seal part 60 which has not peeled remains in tray 100.

  (12) The handle portion 170 of the package 1 is formed in a portion of the tray 100 that faces the opening portion 30. For this reason, when the opening part 30 is separated from the bag main body part 20, the handle part 170 is exposed through the opening formed in the bag main body part 20. For this reason, the user can easily grasp the handle 170. For this reason, the user can take out the tray 100 easily. Therefore, the package 1 can suppress that a user touches a high temperature part.

  (13) Since the handle portion 170 of the package 1 has been subjected to anti-slip processing, the user's hand is less likely to slip relative to the handle portion 170. For this reason, the effect of reducing the discomfort of the user is enhanced.

  (14) The exterior bag 10 may be in close contact with the tray 100 due to water vapor generated inside. When the outer bag 10 is in close contact with the handle portion 170, the user needs to remove the outer bag 10 from the handle portion 170. For this reason, there is a high possibility that the user's hand touches the hot part.

  The handle portion 170 of the package 1 is formed at a location below the tray seal surface 162. For this reason, compared with the case where it is assumed that the handle portion 170 is formed at a location having the same height as the tray seal surface 162 or a location in the upward direction ZC1 with respect to the tray seal surface 162, the outer bag 10 has a handle portion. It is difficult to adhere to 170. For this reason, the packaging body 1 reduces the possibility that the user will feel uncomfortable.

  (15) The tray 100 accommodates the contents 200. The contents 200 generate water vapor when heated. The generated water vapor accumulates at the bottom of the outer bag 10. For this reason, the bottom part of the exterior bag 10 and the bottom wall 140 of the tray 100 may adhere to each other due to moisture. When the bottom portion of the outer bag 10 and the bottom wall 140 of the tray 100 are in close contact, the tray 100 is difficult to be removed from the outer bag 10.

  The bottom wall 140 of the tray 100 has an outer concavo-convex processed portion 143. For this reason, when moisture exists at the bottom of the exterior bag 10, the bottom of the exterior bag 10 and the bottom wall 140 of the tray 100 are difficult to adhere. For this reason, the package 1 is less likely to be difficult to remove the tray 100 from the outer bag 10.

  (16) The package 1 has an advantageous effect over the package disclosed in JP 2011-240954 A (hereinafter referred to as “first comparative package”). The first comparison package has a tray and a tray seal. The tray has a shape that accommodates the contents. The tray has an opening. The tray seal seals the opening of the tray.

  As for the 1st comparison package, the range which can describe explanation of goods etc. is limited to the area of a tray seal. That is, it is difficult for the first comparative package to describe the description of the product or the like beyond the range where the tray opening is formed.

  On the other hand, the package 1 has an exterior bag 10. The exterior bag 10 has a printing layer. The outer bag 10 has a role of closing the opening 151 and a role of wrapping the tray 100. For this reason, the package 1 can close the opening 151 and can describe the description of the product in a wider range than the range in which the opening 151 is formed.

  (17) The package 1 has an advantageous effect over the package disclosed in JP-A-11-139465 (hereinafter referred to as “second comparative package”). The second comparison package has an outer bag and a tray. The exterior bag has a structure for sealing the tray. The tray has a receiving portion. The accommodating part has a structure for accommodating the contents. The accommodating part has a peripheral wall. The accommodating part is opened in a part of the peripheral wall. The exterior bag of the second comparative package accommodates the tray without sealing the opening of the tray. For this reason, there is a possibility that the contents leak from the tray into the internal space of the outer bag.

  On the other hand, the exterior bag 10 of the package 1 has a role of closing the opening 151 and a role of wrapping the tray 100. For this reason, the package 1 can reduce the number of materials constituting the package 1 and can prevent the contents 200 from leaking from the tray 100.
