Description

Technical Field

[0001] The utility model relates to the technical field of bags, in particular to a magnetic waterproof bag. Background Art

[0002] In order to improve the closing efficiency of the bag opening, modern designs usually install magnetic strips on both sides of the bag opening. These magnetic strips can be two magnetic strips with opposite magnetic poles, or a combination of a magnetic strip and an iron bar. When closing the bag opening, the magnetic strip and the corresponding matching part will quickly attract together to achieve a quick closure.

[0003] However, since the magnetic strips and patches have the property of attracting each other at any position, especially when two magnetic strips with opposite magnetic poles are used, even if the two magnetic strips are not precisely aligned, they can be closed due to magnetic attraction. In this case, the bag opening may not fit tightly and leave a gap.

[0004] In order to solve this problem, users often need to reopen the bag opening and ensure that the magnetic strip can be accurately aligned before closing it, which makes the process of closing the bag opening cause some inconvenience to the user. Utility Model Content
