め製品にも価格の上で影響を与えている。The above-mentioned conventional dispensing tools (C) and (D) each have an overall height of about 20 mm from the mounting flange to the paper container body. Therefore, even if this can be attached to the blank plate before assembling the paper container in advance, since the pouring tool will protrude from the blank plate surface by about 20 mm, after assembling it into a rectangular cylindrical shape, it is pressed flat. It is not suitable for a series of filling and sealing devices in the closed state. Therefore, in the case of using the above-mentioned conventional dispensing device, a supply and attachment device for the dispensing device must be incorporated in a series of filling and sealing devices, and this device is used for filling and sealing other contents liquids. Since the device is different from the device and complicated, the device becomes large and complicated as a whole, which in turn affects the price of a product packed in a paper container such as a beverage.

It is welded to the portion (5) with the mounting flanges (6) and (6 '). Since the spouting tools (A) and (A ') are attached at the time of the blank plate before the assembly of the container body (B), the attaching device is a conventional assembled container body (B). ) Is not so complicated as to be inserted and mounted from the inner surface thereof, so that the mounting operation is simple and efficient. The blank plate to which the dispensing tools (A) and (A ') are attached is assembled into a rectangular tube in the same manner as in a normal case, and is subjected to a series of filling and sealing devices while being pressed flat. But,
Since the dispensing device does not protrude greatly unlike the conventional one, there is no problem in the process. The mounting position of such dispensing tools (A) and (A ') is the inclined roof of the paper container.

In order to pour out the content liquid from the paper container main body (B), first, in the pouring tool (A), a fingertip is inserted from the recessed portion (18) to raise the opening gripping portion (b) to open the picking opening (10). When it is picked and pulled, the connecting part (1) of its thin tip (12)
Since a large pulling force is applied to 3), an initial separation occurs in the thin portion (1) for opening at this portion, and this separation spreads to the thin portions (1) and (1) on both sides, and is used for pivotal support. Thin part (2)
Is opened. The opened lid (3) hooks and holds the gripping part (b) on the top sealing part (22) of the container body (B) as necessary. When the container body (B) is tilted, the content liquid flows out from the pouring beak (16). When the opened lid (3) is returned to its original position and closed, the gripper (b) returns to its original state and follows the surface of the spout tool body (a), that is, the surface of the lid (3). In another embodiment shown in FIG. 5, the step (1) of the holding portion (b ′) for opening is used.
9) With a fingertip, the engaging recess (20) is removed from the locking projection (21) of the dispensing tool body (a '), and the knob opening (1) is opened.
0 ′) is picked, and the grip portion (b ′) is pulled to open the thin opening portion (1 ′). After the container body (B) has been tilted and the content liquid has flowed out of the pouring beak (16 '), the container is closed and the opening grip (b') is returned to the original position to engage the engaging recess (20). Engage with the stop projection (21).

手段である。The flat spouting device for paper containers of the present invention is formed by injection molding the whole with a synthetic resin. However, before it cools and hardens, it is bent from the thin portion at the base of the connecting portion of the opening gripper with the spout tool body and solidified in a state along the spout tool body, as a whole. An extremely thin flat plate can be mass-produced, whereby it can be attached in advance to a blank plate before assembling the paper container main body. Since it can be stacked in the pressed state and can be subjected to a series of filling and sealing devices as in the past, it is possible to omit the supply and mounting of foreign and complicated dispensing tools in the conventional series of devices. , That's just the work ability It is possible to lower the production cost of paper packaged product of the beverage liquid by increasing the. Moreover, the opening gripper is injection-molded in a state of protruding upward with respect to the pouring tool body, and before the gripper cools and hardens,
Since this is merely bent and hardened from the thin portion of the base portion, it is easy to obtain a flat dispensing tool in a state where the holding portion for opening is aligned with the dispensing tool body by simple means. it can. This means that, in order to obtain a flat spouting tool in a state in which the unsealing grip is arranged along the spouting tool main body, after performing injection molding with the unsealing gripping part protruding with respect to the spouting tool main body, the following process is performed. If the opening grip is bent from the thin portion and solidified along with the spout body, it takes time and effort to produce, and the opening grip is moved along the spout body. Injection molding in such a state is performed because the mold becomes complicated, the die cutting becomes troublesome, and injection molding becomes difficult. Therefore, the configuration according to the present invention is an effective means in consideration of mass production.
