Detailed Description

The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-6, there is shown an embodiment of a packaging container 100 having a reusable child-resistant zipper structure that is resistant to easy opening by a child. The packaging container 100 includes a first casing 10 and a second casing 20. The first casing 10 and the second casing 20 can be sealed (e.g., by heat sealing) by the left side 31, the right side 32 and the bottom 33, so that an accommodation space 40 can be formed by the inner side surface 34 and the inner side surface 35. In one embodiment, the first housing 10 and the second housing 20 are separate sheets, and the top edge 36 of the first housing 10 and the top edge 37 of the second housing 20 form the opening 45 of the accommodating space 40.

Although the packaging container 100 is shown as being rectangular, it should be understood that the packaging container 100 may have other shapes. Also, the packaging container 100 may be constructed of a variety of materials, including thermoplastic composites and single materials, such as polyethylene.

As shown in fig. 2A and 2B, the packaging container 100 further includes a zipper structure 70, and the zipper structure 70 includes a first side zipper structure 80 and a second side zipper structure 90. The first side zipper structure 80 and the second side zipper structure 90 can be cooperatively connected with each other to close the opening 45 of the packaging container 100 so as to be in a closed state.

In one embodiment, the first side zipper structure 80 includes a first connecting portion 82 and a first free portion 83 disposed opposite the first connecting portion 82. In some embodiments, the first free portion 83 of the first side zipper structure 80 is not directly connected with the inner side surface 34 of the first casing 10, and the first connecting portion 82 of the first side zipper structure 80 is connected with the inner side surface 34 of the first casing 10.

In one embodiment, the second side zipper structure 90 includes a second coupling portion 92 and a second free portion 93 disposed opposite the second coupling portion 92. In some embodiments, the second free portion 93 of the second side zipper structure 90 is not directly connected with the inner side surface 35 of the second case 20, and the second connecting portion 92 of the second side zipper structure 90 is connected with the inner side surface 35 of the second case 20.

The part of the first shell 10 located at the upper side of the first side zipper structure 80 is a first flap 11, and similarly, the part of the second shell 20 located at the upper side of the second side zipper structure 90 is a second flap 21.

Referring again to fig. 2B, in one embodiment, the first side zipper arrangement 80 includes at least two asymmetric female connection portions 81 and the second side zipper arrangement 90 correspondingly includes at least two asymmetric male connection portions 91. Each female connection portion 81 has a first hook connection portion 84, and each male connection portion 91 has a second hook connection portion 94, respectively, the first hook connection portion 84 facing away from the lower side of the second hook connection portion 94, and the second hook connection portion 94 facing away from the upper side of the first hook connection portion 84. For example, the tip of the hook structure of the first hook coupling portion 84, i.e., the end of the free end 85, is directed toward the bottom edge 33 of the first housing 10, and the tip of the hook structure of the second hook coupling portion 94, i.e., the end of the free end 95, is directed toward the top edge 37 of the second housing 20.

The first and second hook connections 84, 94 are interconnected when the first and second

side zipper structures

80, 90 are operatively connected and close the container.

The first side zipper structure 80 and the second side zipper structure 90 are operatively disconnected, and the female connection portion 81 is configured to be rotated with respect to the male connection portion 91 to disconnect the correspondingly disposed first hook connection portion 84 from the second hook connection portion 94, thereby placing the container in an open state. For example, the female connection portion 81 is configured to be rotatable relative to the male connection portion 91 such that the free end 85 of the first hook connection portion 84 is turned toward the top edge 36 of the first housing 10 and the free end 95 of the second hook connection portion 94 is turned 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 downward force directed to the second connecting portion 92 of the second side zipper structure 90 is simultaneously applied to the second side zipper structure 90 to release the connection between the first side zipper structure 80 and the second side zipper structure 90. When operated in this manner, as the first flap 11 and the second flap 21 are torn apart, the first side zipper structure 80 and the second side zipper structure 90 are rotated relative to each other to disconnect the two.

In contrast, referring to fig. 6, when the first flap 11 and the second flap 21 are subjected to a force to be torn apart, but a downward force directed toward the second coupling portion 92 is not applied, the first side zipper structure 80 and the second side zipper structure 90 are configured to maintain the coupled state. When the first and

second flaps

11 and 21 are torn apart in this manner, the second free portion 93 of the second side zipper structure 90 and the first free portion 83 of the first side zipper structure 80 are respectively pulled in a direction away from the second housing 20 and the first housing 10, which makes the tendency of the first side zipper structure 80 and the second side zipper structure 90 to relatively rotate in the weakest state, thereby preventing the connection between the first side zipper structure 80 and the second side zipper structure 90 from being released.

Therefore, through the arrangement of the first free portion 83 of the first side connecting structure 80 and the second free portion 93 of the second side connecting structure 90, when the first turning piece 11 and the second turning piece 21 are pulled, the first free portion 83 of the first side connecting structure 80 and the second free portion 93 of the second side connecting structure 90 of the connecting structures are pulled to rotate to the horizontal state, so that the connection between the first side connecting structure 80 and the second side connecting structure 90 is difficult to be released, and the packaging container 100 is ensured to be difficult to be opened. Meanwhile, the female connection portion 81 and the male connection portion 91 are arranged, so that the first side connection structure 80 and the second side connection structure 90 can be disconnected through relative rotation.
