  • Patent number: 5318549
    Abstract: A urine bag includes a bag body made of a urine impermeable paper and an absorbing body made of an absorbent material which can absorb urine. The bag body has an open upper end and a middle folding line along which the paper is folded so as to define a front sheet and a back sheet on both sides of the middle folding line. Two sides of the front sheet are coupled with two sides of the back sheet so as to define an accommodating chamber between the front and back sheets. Each of the front and back sheets has a curved end edge and a curved cover folding line between which a generally olive-shaped cover portion is defined. The olive-shaped cover portions of the front and back sheets can be folded to overlap each other so as to close the open upper end of the bag body.
