方法が実施又は提案されている。(Prior Art) Gable-top or brick-type liquid paper containers are designed so that a pouring spout is created by peeling off the heat-welded portion at the top or cutting it off with scissors. With the exception of small-sized containers that have a hole for inserting a straw, it has been desired to improve the opening method described above for regular-sized containers. As a means to solve this problem, methods of attaching a screw-type spout or inserting a spout with a sharp tip have been implemented or proposed.

を特徴とする。(Means for Solving the Problems) The present invention provides a paper container having a thermoplastic resin layer on the front and back surfaces. A long and narrow punched hole is provided, and then this hole is filled with thermoplastic resin. At this time, the knob is molded integrally with the thermoplastic resin, and the transparent hole is formed with respect to the filled portion of the thermoplastic resin. The present invention is characterized in that it has a spout which is configured to form a thin walled portion along the hole so that the filled portion is easily torn by the thin walled portion when the knob is pulled up.

できる。(Function) When the through holes provided in the paper container are filled with thermoplastic resin, the resin in the filled portion is completely fused to both or one of the thermoplastic resins on the front and back surfaces of the paper container, improving the sealability of the container. will definitely be maintained. To open the lid, pull up on the knob and tear the filling part along the line of the thin wall to lift the paperboard that will become the lid, making it possible to pour out the contents. Furthermore, when pouring out the contents from the opened spout, the knob can be pressed with a finger to prevent the contour piece of the spout from returning to its original position and blocking the opening.

Figure 2 is a perspective view of the main part of the paper container before the filling part is formed;
FIG. 3 is a sectional view taken along line A-A in FIG. The paper container 1 is a container commonly used for milk, alcoholic beverages, etc., and is made of paperboard with thermoplastic resin such as polyethylene laminated on the front and back sides to improve sealability and suitability for assembly by heat-sealing. is considered to be in good condition. Of course, in the laminated state, a layer with an aluminum foil layer or a gas barrier resin layer as the base can also be used in the same way. As shown in FIG. 2, the paper container 1 has an elongated through hole 2 cut out through the entire thickness of the paper container in the outline of the spout as shown in FIG. Fill and seal to form filling section 3. At the same time, the knob part 5 is molded integrally with the filling part 3 using this thermoplastic resin. The filling part 3 has a third
As shown in the figure, a thin wall portion 7 is formed, and this thin wall portion 7 forms a line along the through hole 2.

便宜を考慮したものであれば良い。 Injection molding is most suitable for forming the filling part 3, the knob part 5, and the thin part 7, and they can be formed at the same time. In addition, the shape of the through hole 2 is U-shaped,
It may be of any shape, such as a V-shape or a combination thereof, as long as it takes into account the operation of the spout opening by tearing the filling part 3 along the line of the thin-walled part 7 and the convenience of pouring out the contents.

ことは、開口操作を容易する効果がある。 Further, as shown in FIG. 3, forming a protrusion 4 on the filling portion 3 that appears on the outer surface of the paper container is effective in preventing dripping during pouring. This protrusion 4 may be provided only at the center of the pouring cup.
In addition, as in the modification shown in FIG. 4, the thermoplastic resin of the filling part 3 can be directly fused to the thermoplastic resin layers on both the front and back surfaces of the paperboard that is the material of the paper container.
This is most preferable in order to eliminate the possibility of a decrease in the strength of the paperboard due to the unavoidable permeation of the content liquid after opening, and at the same time, configuring the thin wall portion 7 from both the front and back surfaces of the filling portion 3 has the effect of facilitating the opening operation. There is.
