An opening device for a flexible package having an opening portion defined by two side walls and a width, the opening device intended to be disposed in the opening portion of the package adjacent to an opening, formed upon initial opening of the package, for opening and closing thereof. The opening device comprises a thin-walled first body with a contact surface and a first application surface opposite thereto for allowing application of the first body in the opening portion to a first of the two side walls. The first body is maneuverable, by folding about a first folding axis, between a basic position and a sealing position. In the sealing position, the contact surface has sub portions directly facing each other. A locking member is designed for releasable locking of the body in the sealing position.

Resealable opening device and package comprising such an opening device

An object is to secure a sufficient area for bonding a spout open/close member ( ). A packaging container has a pair of seal portions; at least five side-surface panel portions ( ) for forming a circumferential wall; an end-surface panel portion ( ) disposed between the seal portion and the side-surface panel portions ( ) and adapted to form a polygonal end-surface portion in cooperation with an intermediate portion ( ) of the seal portion; and flap portions ( ) projected, together with end portions ( ) of the seal portion, from the end-surface panel portion ( ), each of the flap portions ( ) being bent toward a specified panel portion ( ) among the side-surface panel portions ( ) and being welded to the specified panel portion ( ). In this case, since the flap portions ( ) are welded to the specified panel portions ( ), and the end-surface portion is thus made substantially flat, a sufficiently large flat area can be secured on the end-surface portion.
