The second portion 62 of the second extension 60 is located between the first portion 61 of the second extension 60 and the top edge 37 of the second housing 20.

Referring to fig. 3A and 3B, in one embodiment, the first side connecting structure 80 is connected to the first extension 50 and is connected to a position above the first portion 51 of the first extension 50 and below the second portion 52 of the first extension 50. Similarly, a second side attachment structure 90 is also coupled to the second extension 60 and is attached to the second extension 60 at a location above the first portion 61 of the second extension 60 and below the second portion 62 of the second extension 60. In one embodiment, the portion of the first extension 50 between the first side connection structure 80 and the first portion 51 of the first extension 50 is not connected with the first housing 10. Similarly, the portion of the second extension 60 between the second side attachment structure 90 and the first portion 61 of the second extension 60 is also not attached to the second housing 20.

The first portion 51 of the first extension 50 and the first portion 61 of the second extension 60 are connected with the first housing 10 and the second housing 20, respectively, and form a connection surface. However, it should be understood that the first and

second extensions

50, 60 include portions that extend rearwardly from the first and

second portions

51, 61, such as the extension 56 and the extension 66 shown in the figures.

As shown in fig. 3A, the first extension portion 50 further includes two side portions 53 respectively adjacent to the left side 31 and the right side 32 of the first housing 10, and a central portion 54 located between the two side portions 53. In some embodiments, a portion of each side portion 53 of the first extension 50, which is located at an upper side of the first side connecting structure 80 of the zipper structure 70, is provided with a connecting portion 55, the connecting portion 55 is connected with the first housing 10, but the central portion 54 of the first extension 50 is not connected with the first housing 10 at a position higher than the first portion 51 of the first extension 50. In a further embodiment, the connecting portion 55 of each side edge portion 53 of the first extension 50 is connected to the first casing 10 by means of heat sealing. Of course, it should be understood that, in addition to the example of the present embodiment in which one central portion 64 and one central portion 54 are provided in the middle, it is also possible to provide a plurality of the central portions 54 between two side portions 53, a plurality of the central portions 64 between two side portions 63, a portion connected to the first housing 10 between two adjacent central portions 54, and a portion connected to the second housing 20 between two adjacent central portions 64 to separate the plurality of the central portions 54 from the central portions 64.

As shown in fig. 3B, the second extension portion 60 further includes two side portions 63 respectively adjacent to the left side 31 and the right side 32 of the second housing 20, and a central portion 64 between the two side portions 63. In some embodiments, the portion of each side portion 63 of the second extension 60 that is located at the upper side of the second side connecting structure 90 of the zipper structure 70 is provided with a connecting portion 65, the connecting portion 65 is connected with the second housing 20, but the central portion 64 of the second extension 60 is not connected with the second housing 20 at a position higher than the first portion 61 of the second extension 60. In a further embodiment, the connection portion 65 of each side edge portion 63 of the second extension 60 may be connected to the second case 20 by means of heat sealing.

These arrangements result in openings at the central portion 54 and the central portion 64 to guide the user's thumb between the first flap 11 and the central portion 54 of the first extension 50 and between the second flap 21 and the central portion 64 of the second extension 60. Further, by increasing the rigidity of the side portion 63 of the second extension 60 and the side portion 53 of the first extension 50, the opening force of the user can be concentrated at the first portion 51 of the first extension 50 at the central portion 54 and the first portion 61 of the second extension 60 at the central portion 64, thereby facilitating the opening.

In other embodiments, the second portion 52 of the first extension 50 is not connected with the inner side surface 34 of the first housing 10, and the second portion 62 of the second extension 60 is not connected with the inner side surface 35 of the second housing 20.

As shown in fig. 2B, in one embodiment, the first side connection structure 80 includes at least three asymmetric female connection portions 81, and the second side connection structure 90 correspondingly includes at least three asymmetric male connection portions 91. At least one of the at least three asymmetric female connection portions 81 includes a first hook connection portion 84 and at least one of the at least three asymmetric male connection portions 91 includes a second hook connection portion 94. The tip of the hook structure of the first hook coupling portion 84 is disposed toward the top edge 36 of the first housing 10, and the tip of the hook structure of the second hook coupling portion 94 is disposed toward the bottom edge 33 of the second housing 20.

The first hook connection 84 is in close connection with the second hook connection 94 when the first side attachment structure 80 is operatively connected to the second side attachment structure 90 and the container is closed.

The first side connection 80 and the second side connection 90 are operatively disconnected, and the female connection 81 is configured to rotate relative to the male connection 91 to disconnect the first hook connection 84 from the second hook connection 94 to place the container in an open state. For example, the female connection 81 is configured to rotate relative to the male connection 91 to turn the free end 85 of the first hook connection 84 toward the top edge 36 of the first housing 10 and to turn the free end 95 of the second hook connection 94 toward the bottom edge 33 of the second housing 20.

Referring to fig. 4 and 5, when the first flap 11 and the second flap 21 are separated by tearing, a force is applied to a position where the first flap 11 and the second flap 21 are located at the lower side of the zipper structure 70, so that the first portion 51 of the first extension 50 and the first portion 61 of the second extension 60 are separated from each other when the first flap 11 and the second flap 21 are separated by tearing from each other, and at the same time, the first side edge connecting structure 80 and the second side edge connecting structure 90 can be separated from each other at this time. Opening the first container case 100 in this manner enables the first side connection 80 and the second side connection 90 to be separated from each other from the bottom to the top. In other words, the first flap 11 and the second flap 21 are urged at the lower side of the zipper structure 70 so that the female coupling portion 81 and the male coupling portion 91 are separated from each other one by one from the bottom up.

However, referring to fig. 6, when the first flap 11 and the second flap 21 are torn apart without applying force to the portions of the first flap 11 and the second flap 21 located at the lower side of the zipper structure 70 such that the first portion 51 of the first extension 50 and the first portion 61 of the second extension 60 are separated from each other, the first side connecting structure 80 and the second side connecting structure 90 are configured to still maintain the releasable coupling state. When the first flap 11 and the second flap 21 are torn apart in this way, the opening force is concentrated on the bottom 93 of the second side connecting structure 90, so that the tendency of the first side connecting structure 80 and the second side connecting structure 90 to rotate relative to each other is at the weakest state, preventing the first side connecting structure 80 and the second side connecting structure 90 from being detached from the zipper structure 70 from the bottom upward.
