採用されている。[0003] Incidentally, the retort sterilization treatment must be performed in a state where the inside of the container is completely sealed. However, simply closing the mouth of the container with a screw cap cannot ensure sufficient sealing performance. In such a container with a screw cap, an inner seal having a knob for peeling is heat-sealed to the open end of the mouth so that the contents can be peeled off after use after filling the container. The method of sealing is generally adopted.

パウチ容器が使用されるようになってきている。Recently, as a container for storing food such as a liquid beverage as described above, as shown in FIG. 4, a flexible sheet having a heat-adhesive inner surface laminated with an aluminum foil or the like on a synthetic resin film is used. In addition to forming a bag-shaped container body 50 by heat sealing, a spout 60 having a mouth serving as a spout or a drinking mouth is attached to the container body 50, and the mouth of the spout 60 is screwed with a screw cap 70. Pouch containers with spouts that open and close have been used.

Must be closed by an inner seal. However, the mouth of the pouch container with spout
Since the caliber is relatively small, an inner seal like that used in a general container with a screw cap, that is, a knob for peeling is continuously provided in a closed portion formed in substantially the same shape as the mouth. As shown in FIGS. 5A to 5C, a screw cap is used in a state where a rectangular inner seal 80 larger than the mouth is heat-sealed to the open end of the mouth 61 without using such an inner seal. 70 is attached. Then, in a state where the purchaser of the product removes the screw cap 70, the portion 81 that protrudes outward from the mouth portion 61 of the inner seal 80 is picked, and the inner seal 80 is peeled off from the mouth portion 61, thereby removing the mouth portion 61. Can be opened.

むことができなくなるといった問題がある。Normally, there is almost no gap between the mouth portion 61 of the spout 60 and the screw cap 70. Therefore, as described above, the projecting portion 81 of the inner seal 80 is complicatedly folded and overlapped. 6, the projecting portion 81 of the inner seal 80, which becomes a knob for peeling, is formed by the inner peripheral surface of the screw cap 70 so that the outer peripheral portion of the mouth 61 is sandwiched between the portion 61 and the screw cap 70. Surface, and the heat (for example, 121 to 125 ° C.) when performing the retort sterilization process causes the overhang portion 81 of the inner seal 80 to be heat-sealed to the outer peripheral surface of the mouth portion 61 to purchase the product. Is the inner seal 8
There is a problem that, when the 0 is peeled off, the protruding portion 81 cannot be picked as a knob.

うな隙間を形成したのである。Means for Solving the Problems and Their Effects To solve the above-mentioned problems, the present invention provides a container body formed in a bag shape by a flexible sheet, and a cylindrical mouth serving as a spout or drinking mouth. A spout attached to the container body so as to protrude, and the spout is peelably heat-sealed to an open end of the mouth of the spout to close the open end, and peeling outward from the mouth. A pouch container with a spout, comprising: an inner seal having a knob portion for use; and a screw cap detachably attached to the mouth by screwing into an external thread formed on the outer peripheral surface of the mouth of the spout. In the above, between the mouth of the spout and the screw cap, a knob of the inner seal folded on the outer peripheral surface side of the mouth of the spout is provided. Serial it by the inner peripheral surface of the screw cap of the formation of the gap so as not pressed against the outer peripheral surface of the mouth portion of the spout.

から剥離する際、確実に摘み部を摘むことができる。[0010] In the pouch container with a spout configured as described above, with the screw cap attached to the mouth, the knob of the inner seal folded into the outer peripheral surface side of the mouth has the inner peripheral surface of the screw cap. Because the spout is not pressed against the outer peripheral surface of the mouth portion, even when retort sterilization is performed after filling the contents, the heat causes the knob of the inner seal to be firmly fused to the outer peripheral surface of the mouth portion. When the inner seal is peeled from the mouth, the knob can be reliably picked.

できる。The gap between the mouth portion and the screw cap may be formed by increasing the thread of the male screw on the spout side into which the screw cap is screwed. As described in 4, the spout can be formed by reducing the outer diameter of the spout at the mouth portion on the tip side from the male screw.

The gap L between the outer peripheral surface of the mouth 22 and the screw cap 30 is about 4 to 6 times the thickness of the inner seal 40.
(Approximately 0.4 mm), so that the rectangular inner seal 4 is heat-sealed to the open end of the mouth 22.
Even if the projecting portion 41 outwardly extending from the mouth 22 of the 0 is folded into the outer peripheral surface side of the mouth 22 while being complicatedly folded, the projecting portion 41 is formed by the inner peripheral surface of the screw cap 30. The inner seal 4 is not strongly pressed against the outer peripheral surface and is heated by the heat during the retort sterilization.
The overhang portion 41 of 0 is not firmly fused to the outer peripheral surface of the mouth portion 22.

うになっている。In the above-described pouch container 1 with spout,
By making the height of the thread of the male screw 24 formed on the mouth 22 of the spout 20 higher than the height of the thread of the female screw 31 formed on the inner circumferential surface of the screw cap 30, the outer circumferential surface of the mouth 22 and A predetermined gap L is formed between the screw cap 30 and the inner peripheral surface thereof. In this pouch container with a spout, the mouth 2 of the spout 20a is formed.
The screw thread of the male screw 24a formed on the inner screw 2a and the screw thread of the female screw 31 formed on the inner peripheral surface of the screw cap 30 have substantially the same height. By reducing the outer diameter,
In other words, by reducing the thickness of the mouth 22a on the tip side from the male screw 24a, the spout 20a
A gap L ′ of about 0.55 mm is formed between the outer peripheral surface of the opening 22a and the inner peripheral surface of the screw cap 30.

When the screw cap 30 is attached after the heat seal at the open ends of the portions 22 and 22a, the inner seal 40 is less likely to be damaged by the screw cap 30, so that the reliability of the inner seal 40 for sealing the container is improved. There is also an effect.

ある。In the embodiment described above, the mouth 22,
The gap between the outer peripheral surface of 22a and the inner peripheral surface of the screw cap 30 is set to 0.4 mm or 0.55 mm, but is not limited to this. However, while the projecting portion 41 of the inner seal 40 serving as the knob portion is complicatedly folded and overlapped, the mouth portions 22 and 22a and the screw cap 30 are not folded.
If it is folded between the mouth 22, 22a
The gap between the outer peripheral surface of the inner seal 40 and the inner peripheral surface of the screw cap 30 needs to be set to at least three times or more, more preferably about four to eight times the thickness of the inner seal 40.
