  The liquid paper container with a stopper composed of a prismatic body and a flat bottom part is connected to the front panel and the top part with the stopper, but is connected to each other through a crease. Therefore, when pouring the liquid as the contents, if the container is tilted, the liquid changes in the creased part, becomes turbulent, and does not flow smoothly from the plug. In addition, the flow from the spout is intermittent and difficult to pour out.

  An object of the present invention is to solve such drawbacks and to provide a liquid paper container with a stopper so that the liquid can be smoothly poured out when the liquid as the contents is poured out.

The present invention has been made in view of the above problems, and the invention of claim 1 is directed to a top panel having a plug, a front panel, a back panel facing the front panel, the front panel, and the back panel. A pair of side panels connected to both right and left ends of the bottom panel are connected to the top panel at their upper ends, and are connected to the front panel, the back panel, and the bottom ends of the pair of left and right side panels. The top panel is a curved surface that curves from the front to the back, and the front lower end of the top panel is connected to the upper end of the flat front panel, The curved surface and the plane of the front panel are continuous without a crease line , and V-shaped ruled lines or C-shaped lines are formed on the lower end portion of the top panel and the left and right ends of the connecting portion of the upper end portion of the front panel. Character-shaped ruled lines open to each other Is the spout with liquid paper container according to claim 1, characterized in that is provided so as to match buy

In the invention of claim 2, a pair of V-shaped ruled lines or C-shaped ruled lines are open at the left and right ends of the boundary line between the lower end of the top panel and the upper end of the front panel. The V-shaped intersection or the C-shaped extended line is located at the boundary line so that the V-shaped or C-shaped opening angle is 15 degrees to 45 degrees with respect to the boundary line. 2. The liquid paper container with a cap according to claim 1, wherein the liquid paper container has a mouth angle.

The stopper-equipped liquid paper container of the present invention is configured as described above, and the top panel has a curved surface that curves backward from the lower end, and the upper end of the front panel has a lower end that is flat. Since the curved surface of the top panel and the plane of the front panel are continuous without a crease, when the liquid as the content is poured out, the liquid that is the content at the crease portion It is poured out smoothly without being disturbed.
In addition, a pair of V-shaped ruled lines or C-shaped ruled lines are provided so that their open ends face each other, so that the curved surface of the top panel and the plane of the front panel do not need to be creased. A continuous liquid paper container with a stopper can be formed.

  The liquid paper container with a stopper of the present invention has a smooth flow without being disturbed between the front panel and the top panel when the container is tilted to pour out the liquid as the contents. Therefore, the spout of the spout is not intermittent and easy to pour out.
