Liquid container sealing jacket, and method for unsealing liquid container fitted with liquid container jacket

A packaging structure for a liquid container including a liquid containing portion accommodating liquid, a liquid supply portion for supplying the liquid to an outside, and an air vent for fluid communication with an ambience,

• wherein said liquid container is substantially in the form of a polyhedron shape substantially constituted by a plurality of sides including one side having said air vent, an opposite side having said liquid supply portion, a first vertical side, and a second vertical side which is opposed to said first vertical side with said one side and said opposite side therebetween;
• said packing structure comprising:
• a covering member for covering and sealing said liquid supply portion and said air vent, said covering member including:
• an air vent sealing portion for sealing said air vent,
• a liquid supply portion sealing portion for sealing said liquid supply portion, wherein said liquid supply portion sealing portion includes a capping member, and first and second connecting regions for respectively covering the first and second vertical sides of said liquid container, and which respectively connect said air vent sealing portion and said liquid supply portion sealing portion,
• wherein said first connecting region has a first adhesive region which is adhesively adhered to the first vertical side, said second connecting region has a second adhesive region which is adhesively adhered to the second vertical side, and said liquid supply portion sealing portion is not adhesively adhered to said opposite side,
• wherein said second adhesive region of said covering member has a perforation to provide a degree of resistance against tearing;
• and
• wherein said first adhesive region remains adhered to the first vertical side even after said second adhesive region has been peeled from the second vertical side.
