Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pouring stopper for a liquid container.

[Prior Art] Conventionally, a paper container such as a Gobel top type has been used for the purpose of reducing the manufacturing cost and weight of a liquid container. Some of these paper containers are provided with a spout plug so that liquid can be easily poured out from the paper container. An external screw is attached to the spout hole of the liquid container (paper container), and the spout Which has an inner plug arranged inside the cap and a cap screwed onto the spout, and has a structure in which when the inner cap is opened, the inner plug is pushed to break and release the film covering the spout hole. When storing, the cap was fitted into the spout (for example, Jikho Sho 58-37828).
(See the official gazette).

[Problems to be Solved by the Invention] However, in the conventional spouting plug, as described above, the spouting tool, the inner spout and the cap are separately molded, so that the structure is complicated and the manufacturing cost is high. there were.
Also, when this pouring plug is attached to a liquid container, the pouring cap will greatly protrude from the container body, and when pouring or handling the liquid containers, this pouring plug can be placed on other containers etc. There was also the problem of contact and damage.

[Means for Solving the Problems] The present invention has been made in consideration of the above-mentioned conventional problems, and has a hole facing a pouring hole sealed with a rupturable film of a liquid container. A pouring plug comprising a spout and a cap to which the spout is detachably attached, wherein the cap has a blade portion corresponding to a film and into which a hole of the spout is inserted, and the spout To provide a liquid container pouring tool characterized in that a removable stopper for positioning the cap with respect to the pouring tool is interposed between the cap and the cap, and to solve the above-mentioned conventional problems. .

[Operation] In the present invention, the detachable stopper is interposed between the spout and the cap, and when the cap is pushed or screwed in, the stopper comes off, and the blade of the cap breaks the film of the spout hole, The pouring hole will be opened.

[Embodiment] Next, the present invention will be described in detail based on an embodiment shown in FIGS. 1 to 11.

1 to 4 show the first embodiment, in which 1 is a synthetic resin spout, and this spout 1 is located, for example, on the upper slope of a Gobeltop type container. It is attached to the pouring hole a. The spout 1 is composed of a spout 3 having an external thread on the outer surface of a cylindrical peripheral wall 2 and a cap 5 having an internal thread on the peripheral wall 4, and the cap 5 is screwed onto the spout 3 and is removable. Covered.

The spout 3 is attached and fixed to the container by welding the bottom flange 30 to the peripheral edge of the spout hole a via a rupturable film b, and the spout hole a is sealed by the film b. Further, the cap 5 is integrally provided on the back surface of the top portion 50 with a cylindrical blade portion 51 into which the hole 3a of the pouring tool 3 is inserted and which faces the film b.

As shown in FIG. 1, between the peripheral wall 4 of the cap 5 and the base portion 20 of the peripheral wall 2 of the spout 3, a stopper 6 wound around the peripheral wall 2 of the spout 3 is interposed. The blade portion 51 does not come into contact with the film b, the cap 5 is positioned by the stopper 6 when the spout hole a is not opened, and the cap 5 is naturally rotated in the tightening direction (nothing in the tightening direction). In the state in which the rotational force is not applied, for example, rotation or rotation due to vibration or careless contact is prevented. The stopper 6 is easy to cut. For example, as shown in FIG. 2, the stopper 6 has a vertical thin portion 60 which is easy to cut, and the cap 6 is provided with the thin portion 61 which is easy to cut across the lower edge of the peripheral wall 4. 5, the cap 5 is rotated in the tightening direction (the direction of arrow A in FIG. 3) and lowered when the spout hole a is opened. 6 comes off, and the blade part 51 is not removed until the cap 5 is further rotated and lowered.
Comes into contact with the film b and breaks it, so that the pouring hole a can be opened (see FIG. 4). And when pouring out the contents,
By removing the cap 5, pouring can be performed from the pouring tool 3.

The stopper 6 may be separated from the cap 5, and the cap 5 may be rotated and lowered to
It may be cut and removed, or the stopper provided with the finger hook 62 may be detached before the cap is rotated (see FIG. 3). The blade portion 51 may be provided with a partition for preventing pulsation during pouring.

5 to 9 show the second embodiment. In the second embodiment, the spout 3 and the stopper 6 have the same structure as that of the first embodiment. In the cap 5 according to the second embodiment, a spout 52 communicating with a cylindrical blade portion 51 and located at the top 50 is opened, and an opening / closing lid 7 for opening and closing the spout 52 is hinged. It is provided integrally via 70. Also in the second embodiment, the cap 5 is rotated and lowered similarly to the above-described first embodiment, or the stopper 6 is removed in advance and the cap 5 is rotated and lowered so that the spout hole a is formed by the blade portion 51. Just open it up,
The opening / closing lid 7 can be opened to pour out the contents, and it is not necessary to remove the cap 5, which facilitates handling.

10 and 11 show the third embodiment. This third embodiment differs from the first and second embodiments in that
Outer periphery of the cap 5 having no peripheral wall, that is, a jetty 53 extending in the circumferential direction of the blade 51, and a hole into which the blade 51 of the cap 5 is inserted.
A stopper 6 is interposed between the spout 3 and the spout 3 and the cap 5 is positioned with respect to the spout 3 by the stopper 6.

As shown in FIG. 11, the stopper 6 has a tapered peripheral cross-sectional shape and is inclined on the inner surface side. When the spout hole a is opened, the cap 5 is spouted. The jetty 53 of the cap 5 is pushed by pushing it to the 3 side.
The protrusion 54 located at the lower part of the stopper pushes and spreads the stopper 6, and the stopper 6 which is provided with the vertical thin portion 60 and which is integrated with the pouring tool 3 through the thin portion 63 is cut off. As a result, even if another container or the like accidentally comes into contact with the pouring stopper, the cap does not drop, and the opening of the pouring hole can be prevented. Then, the blade portion 51 breaks the film b and opens it so that the contents can be poured out. In the third embodiment, the cap 5 once pushed is desirably positioned and fixed to the pouring tool 3 in that state, and the protrusion 54 is provided on the inner surface of the hole 3a of the pouring tool 3. The cap 5 is provided so as to be fitted in the groove 3b and fixed. Further, similarly to the second embodiment, the cap 5 is provided with the spout 52, and the opening / closing lid 7 for opening and closing the spout 52 can be integrally provided via the hinge portion 70. By thus integrally providing the opening / closing lid 7, it is not necessary to attach or remove the cap, and the contents can be easily and sanitarily poured out by opening / closing the opening / closing lid 7.

[Effect of the Invention] As described above, according to the present invention, the spouting plug has a hole facing the spouting hole of the liquid container sealed with the rupturable film, and the spouting tool. And a cap to which the cap is detachably attached, wherein the cap has a blade portion corresponding to the film and into which the hole of the spout is inserted, and the spout is provided between the spout and the cap. Since there is a removable stopper that positions the cap with respect to, the cap is pushed into the spout side, or if the cap and spout are screwed together as in the past, simply rotate and lower the cap. Then, the pouring hole of the container is opened so that the contents can be poured out, and it is hygienic without touching the blade portion. In addition, since a stopper is interposed between the cap and the spout, the spout hole will not be opened even if other containers inadvertently come into contact with the spout, and it will be easy to find out if it is opened by mischief. It is possible to achieve an effect that is highly practical.
