<p>A bag-in box, wherein an inner bag formed integrally with a liquid spout detachably threaded with a cap or a hose is stored in an outer box in a roughly rectangular parallelepiped shape comprising four side plates forming a body part, a top plate forming a double structure top part, and a bottom plate forming a double structure bottom part. A slit of a roughly channel-shape having a tip extending from a fold line in the direction of the top plate is bent inward along the fold line at a position apart a prescribed distance from the upper end of the side plate arranged continuously with the top plate positioned on the inside of the double structure. A fixed hole for fixedly fitting the liquid spout and an elongated hole allowing a worker to insert a finger therein are formed from the fold line at the portion of the side plate surrounded by the slit to the tip side in this order, and a perforation enabling the cutoff of the portion thereof facing the fixed hole and the elongated hole is formed on the top plate positioned on the outside of the double structure.</p> |
