The angle θ between the outer edge of the body 62a of the head 62b and the outer edge of the body 62a may be less than or equal to a right angle (90 degrees). This makes it easy to maintain the hook portion 62 locked to the main body portion 61.

  In the vertical direction HD, the dimension L1 of the slit 61a is larger than the dimension L2 of the body 62a and smaller than the dimension L3 of the head 62b. The dimension L2 of the body 62a is the dimension of the portion connected to the head 62b. The dimension L1 of the slit 61a is, for example, 4 mm or more and 10 mm or less. The dimension L2 of the body portion 62a is, for example, 3 mm or more and 9 mm or less. The dimension L3 of the head 62b is, for example, 5 mm or more and 11 mm or less.

  The hook portion 62 is engaged with the main body portion 61 in a state where the head portion 62b is inserted into the slit 61a by curving the main body portion 61 so as to protrude in the direction from the first side film 11 toward the second side film 12 It is configured to be possible. The hook portion 62 is cantilevered on the main body portion 61 so as to protrude to the same side as the slit 61 a with respect to one end 621 of the body portion 62 a. In the present embodiment, the hook portion 62 is configured to protrude toward the slit 61 a before the hook portion 62 is engaged with the main body portion 61. Further, even in the state after the hook portion 62 is engaged with the main body portion 61, the hook portion 62 is configured to protrude toward the slit 61a. The head 62b has a taper 62b2 in which the width in the vertical direction HD decreases toward the tip 62b1 of the head 62b. That is, the head 62b is configured to be tapered toward the tip 62b1 of the head 62b. In the present embodiment, the head 62b has a triangular shape whose apex is located at the tip 62b1 of the head 62b.

  Next, with reference to FIG. 4, the structure of the package 1 in the state in which the content 10 is accommodated in the accommodating part 30 is demonstrated. In this state, the package 1 further includes the content 10 stored in the storage unit 30. In the state where the content 10 is stored in the storage portion 30, in the portion to be sealed 23, the other peripheral portions of the first side film 11 and the second side film 12 are sealed. Specifically, in the portion 23 to be sealed, the first side film 11 and the second side film 12 may be sealed by heat welding to each other. Thereby, all the peripheral parts 20 are sealed. Therefore, the storage unit 30 is sealed in a state in which the content 10 is stored in the storage unit 30.

  Next, with reference to FIG. 5, the structure of the package 1 in the state which the opening plan part 50 opened is demonstrated. In this state, as in the state shown in FIG. 4, the package 1 further includes the content 10 stored in the storage unit 30. Moreover, in the state in which the content 10 is stored in the storage part 30, all the peripheral parts 20 are sealed. Further, the planned opening portion 50 is opened so as to communicate the outside of the package 1 with the storage portion 30. Specifically, the opening scheduled portion 50 may be opened, for example, by removing the band-shaped portion of the first side film 11 surrounded by the perforation structure or the half cut structure.

  Since the first side film 11 and the second side film 12 are sealed to each other at the portion to be sealed 23 provided at the upper end of the package 1, the first side film 11 is less likely to bend than the single first side film 11. Therefore, when the portion 50 to be opened is opened, the portion on the bottom film 13 side of the first side film 11 constituting the opening is bent to expand the opening.

  Furthermore, after the planned opening 50 is opened, the user of the package 1 projects the main body 61 in the direction from the first side film 11 toward the second side film 12 as shown by the arrow A in FIG. 5. To be deformed into a curved state. As a result, the hook portion 62 rises from the main body portion 61 in the direction from the second side film 12 to the first side film 11. Specifically, the hook portion 62 stands straight toward the slit 61a. Further, the distance between the hook portion 62 and the slit 61a is shortened. Therefore, when the hook portion 62 reaches the slit 61 a, the head 62 b of the hook portion 62 can be inserted into the slit 61 a from the first side film 11 to the second side film 12.

  In the vertical direction HD, although the dimension L1 of the slit 61a is larger than the dimension L2 of the body portion 62a and smaller than the dimension L3 of the head 62b, the hook portion 62 has the first side film 11 and the second side film 12 Because it is sealed, it can be elastically deformed. After passing through the slit 61a in a state where the dimension L3 of the head 62b of the hook portion 62 is smaller than the dimension L1 of the slit 61a, after passing through the slit 61a, the dimension L3 of the head 62b is greater than the dimension L1 of the slit 61a Will also grow. Therefore, the head portion 62b of the hook portion 62 engages with the second side film 12 in a state of being inserted into the slit 61a. In this manner, the hook portion 62 engages with the main body portion 61. At this time, since the head portion 62 b protrudes from the body portion 62 a in the vertical direction HD, the hook portion 62 is locked to the main body portion 61 in a state in which the hook portion 62 is engaged with the main body portion 61.

  At this time, as shown by arrow B in FIG. 5, the planned sealing portion 23 provided at the upper end of the package 1 is deformed such that both ends in the width direction WD of the package 1 come close to each other. Thereby, as shown by the arrow C in FIG. 5, the part by the side of the bottom film 13 among the 1st side film 11 which comprises an opening curves on the opposite side to the direction which the main-body part 61 curves. Thus, the opening is expanded.

  Then, by holding the state in which the hook portion 62 is engaged with the main body portion 61 in a state in which the opening is expanded, it is curved so as to protrude in the direction from the first side film 11 to the second side film 12 The shape of the main body 61 is maintained. Moreover, the part by the side of the bottom film 13 among the 1st side film 11 which comprises an opening is hold | maintained in the state curved in the opposite side with respect to the direction which the main-body part 61 curves. Thus, the state in which the opening is expanded is maintained.

  In a state in which the hook portion 62 is engaged with the main body portion 61, the slits are formed so that the left and right bisectors of the package 1 and the left and right bisectors of the body 62a overlap in the width direction WD of the package 1 61a and the hook portion 62 may be set. That is, the center line CL in the width direction WD of the body 62 a may be arranged to overlap the center line CL in the width direction WD of the package 1. This makes it possible to expand the opening symmetrically in the width direction WD. Note that one of the body portions 62 a may be disposed so as to overlap the center line CL in the width direction WD of the package 1. This also makes it easy to widen the opening.
