PACKAGING CONTAINER SEALING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/049719
Kind Code:
A1
Abstract:
A packaging container sealing structure comprises: a container body (10); opening portions arranged at the top and bottom of the container body; and first and second cover panels (11, 12) arranged at opposite sides of the opening portion and folded inwardly to seal the opening portion. The first and second cover panels are assembled by combining a protruding insertion frame (20) and a recessed insertion frame (30) which are respectively provided with a protruding fastener and a recessed fastener and arranged at corresponding sealing edges of the cover panels. Upon execution of a sealing operation, the first and second cover panels are sequentially folded to close the opening portion, such that the insertion frames at the opposite sides thereof are stacked with respect to each other to form a sealing line. After the two cover plates have closed the opening portion, the insertion frame having a projecting tongue can be pressed downwardly, such that the protruding fastener and the recessed fastener respectively provided at the two cover panels are joined by snap-fit engagement. The invention enables sealing edges of a container to be assembled and secured easily to form a smooth sealing surface, thereby performing packaging and sealing operations continuously and conveniently.
