Child-resistant sealing pouch

A child-resistant sealing pouch, comprising a double-face pouch body and a seal bar provided at a top of the double-face pouch body, wherein two ends of the seal bar are sealed and fixed on two sides of the double-face pouch body;

• the seal bar comprises a first closing piece and a second closing piece;
• wherein the first closing piece and the second closing piece are respectively provided with a first locking piece and a second locking piece, wherein the first locking piece and the second locking piece are buckled for sealing;
• an upper side of the first closing piece is provided with a first upper extension piece, but a lower side of the first closing piece is not provided with any lower extension piece;
• the first upper extension piece is thermally connected to a first inner side of the double-face pouch body;
• an upper side of the second closing piece is provided with a second upper extension piece, and a lower side of the second closing piece is provided with a second lower extension piece;
• the second lower extension piece is folded upward and thermally connected to a second inner side of the double-face pouch body;
• the second upper extension piece is not thermally fixed to any one of the first inner side and the second inner side of the double-face pouch body;
• the first locking piece is located on the first closing piece;
• the first locking piece comprises at least two first grooves;
• side walls of the at least two first grooves away from the top of the double-face pouch body are respectively bent toward insides of the at least two first grooves to form first inner hooks;
• a prong of the first locking piece closest to the first upper extension forming a downward curve without a hook;
• a prong of the first locking piece farthest from the first upper extension forming a upward curve with a hook;
• the second locking piece is located on the second closing piece;
• the second locking piece comprises at least two second grooves;
• a prong of the second locking piece closest to the second upper extension piece forming a downward curve with a hook;
• a prong of the second locking piece farthest from the second upper extension piece forming a upward curve without a hook;
• side walls of the at least two second grooves close to the top of the double-face pouch body are respectively bent toward insides of the at least two second grooves to form second inner hooks;
• the at least two first grooves are configured to be respectively buckled with the at least two second grooves, the first inner hooks are respectively hooked with the second inner hooks;
• the first upper extension piece of the first closing piece and the second lower extension piece of the second closing piece are configured to be pulled into a plane of 180° to generate a pulling force on the seal bar along a sealing surface, which increases a hooking tightness of the first inner hooks and the second inner hooks with a tearing strength;
• wherein the second upper extension piece and the second lower extension piece of the second closing piece are configured to be pulled until they overlap in order for the sealing pouch to be opened by pinching and tearing outward, and
• wherein when the second upper extension piece and the second lower extension piece of the second closing piece are pulled to be overlapping, a portion of the first locking piece closest to an opening of the sealing pouch and a portion of the second locking piece closest to the opening of the sealing pouch are unbuckled so that a first inner hook and a second inner hook closest to the opening of the sealing pouch may be separated without resistance.
