Title: PAPER-MADE CONTAINER FOR ACCOMMODATING LIQUID CONTENT FOR REFILLING
Abstract:
The present invention includes a body part (11) formed of a body-part front panel (7), left and right body-part side panels (6), (8), and a body-part rear panel (5). An upper surface part (12) is formed of: an upper-part forming panel (14) connected to the upper end of the body-part rear panel (5); an auxiliary upper-part forming panel (16) which is connected to the upper end of the body-part front panel (7) and which is folded under the upper-part forming panel (14); and left and right lateral panels (19), (20) which are connected to the upper ends of the left and right body-part side panels (6), (8), respectively, and which are folded by overlapping of the upper-part forming panel (14) and the auxiliary upper-part forming panel (16). A suction port (21) is provided in the upper-part forming panel (14). The longitudinal length of the auxiliary upper-part forming panel (16) is set such that the auxiliary upper-part forming panel (16) does not reach the suction port (21). A seal panel (24) is connected to an end of the auxiliary upper-part forming panel (16). The seal panel (24) is valley-folded to seal the inner surface thereof and the inner surface of the upper-part forming panel (14) so that the overlapping surfaces of the folded left and right lateral panels (19), (20) are sealed. Consequently, a paper-made container for accommodating a liquid content for refilling is obtained in which sealing of the upper surface part is ensured, from which the probability of liquid leakage is eliminated, and which can be easily produced.
