Description

Technical Field

[0001] The utility model relates to the technical field of packaging covers, and more specifically, to an inverted cover for a soft bag. Background Art

[0002] Most of the soft bags currently in use are fully enclosed. After opening once, it is difficult to reseal them, which is very inconvenient to use. Some soft bags with lids are very simple and convenient to open and reseal, but have poor sealing performance, low pressure resistance, and liquid is easy to leak. In addition, the existing soft bags usually cannot stand on their own after filling items, and are easy to spill during storage. For example, CN201510677473.X discloses such a soft packaging bag. For this reason, we propose a new type of inverted lid for soft bags to solve the above technical problems. Utility Model Content
