Abstract

PROBLEM TO BE SOLVED: To easily peel a spout from a head panel, to improve the volume reduction ratio of a paper container for liquid, and to facilitate the disposal, incineration and recycling by providing a step by notches having the prescribed depth from a bottom side of a flange and the prescribed distance to the end from the outer circumference on an outer end of a part of the flange. SOLUTION: A step by notches 4 having the prescribed depth (d) from a bottom side of a flange and the prescribed distance (w) to the end from the outer circumferential side is provided on an outer edge of a flange 1 of a spout 10. The notches 4 may be provided over the whole circumference of the flange, or intermittent notches 4' on the left half may be acceptable. After the use of the container, the paper container for liquid is lifted by inserting a tool such as a minus screwdriver in the step in the outer circumference of the flange 1 of the spout 10, a cardboard layer on a head panel side of a thermal fusion area is broken, and the spout 10 can be peeled from a head panel by hooking a finger to the step, and lifting it. Thus, the paper container for liquid without any spout 10 can be folded to reduce its volume.

Generally, the spout is firmly heat-bonded to the head panel of the liquid paper container in order to fulfill the function of protecting the physical contents as a package and the function of pouring. When disposing of a paper container after use, it cannot be removed without taking measures such as cutting off the carton blank around the spout with scissors, a knife, etc., and it must be discarded with the spout attached. . Therefore,
Although the body of the paper container can be folded to reduce the volume, the head panel is bulky and there is a problem that the volume of the entire liquid paper container cannot be reduced. The present invention has been made in view of such a problem, and an object of the present invention is to provide a spout that can be easily removed from a carton blank with a simple tool such as a flathead screwdriver after using a liquid paper container.

FIG. 2 is a perspective view of a liquid paper container provided with a spout according to the present invention. Spout 1 according to the invention
FIG. 2A shows a liquid paper container 20 to be attached.
A gable top carton shown in FIG. 2, a flat top carton shown in FIG. 2 (b), a slant top carton modified from the gable top carton shown in FIG. 2 (c), and the like, having a head panel attachable to the head. Any type is acceptable. In order to attach the spout 10 according to the present invention to the head panel of the liquid paper container 20, it is generally necessary to use a book made of a thermoplastic resin like the thermoplastic resin layer around the perforated punching hole of the head panel of the liquid paper container. According to the invention, a method is employed in which a heat bonding area including the convex ribs 3 on the back surface of the flange 1 of the spout 10 is heated by hot air and then both are pressed to perform a hot melt bonding. In this case, the convex ribs 3 shown in FIG. 1B are crushed, and the rear surface of the flange 1 is at substantially the same level as the level L of the head panel surface. Therefore, on the outer periphery of the flange 1, a step having a depth d is formed between the flange 1 and the head panel surface level L.

After the use of the liquid paper container 20, a device such as a flathead screwdriver is inserted into the step on the outer periphery of the flange 1 of the spout 10 according to the present invention and lifted, and the head panel of the heat-sealing area is leveraged. Break the paperboard layer on the side,
Next, if a finger is hung on the step and lifted, the spout 10 can be peeled off from the head panel while delamination of the paperboard occurs. The volume reduction by folding the liquid paper container 20 having no spout is superior to that in which the spout remains, and the container can be almost flatly folded. In this case, if a folding ruled line K composed of, for example, a Y-shaped ruled line and a horizontal ruled line connecting the intersection of the Y-shaped ruled line as shown in FIG. Further, folding becomes easy.

[0008] Low-density polyethylene is generally used for the thermoplastic resin layer on the surface of the carton blank of the liquid paper container. However, if the above-mentioned thermal bonding method is considered, the thermoplastic resin used for the spout 10 according to the present invention is used. It is desirable to use low-density polyethylene for the resin. However, other resins such as a polypropylene resin can be used for the screw cap.
