Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a separate spout stopper that is attached to a paper or other liquid container.

BACKGROUND ART As shown in FIG. 5, a pedestal part 20 of a conventional spout stopper for a liquid container is simply formed by attaching a flange to a joint part 23 of a hollow body part 22 having a thread 21 protruding from its outer surface. 24 are arranged in a row, and the edge of the body 22 is connected to the spout 2.
It was of a shape that is said to be 5. (Jitsukai 1978
-Refer to Publication No. 167023) Problems that the invention aims to solve The spout stopper for a liquid container usually consists of a cap and a pedestal part, and the cap and pedestal part are manufactured separately and then handed over to the liquid container manufacturer. In this case, the cap is screwed onto the pedestal. The production volume of spout plugs is extremely large, and there has been a desire for accurate and speedy attachment of caps to pedestals. Further, since the spout stopper attached to the container is repeatedly removed and attached during use, a structure that prevents the cap from loosening when the cap is resealed has been desired.

Conventionally, a mounting device called a cap has been used to attach a cap to a pedestal. The mounting device, as shown in FIG.
is placed with the flange 24 facing down, and the flange 2
4 from above onto the mounting base 26 with a pressing tool 27 to hold the pedestal part 20 so as not to rotate, and in this state, a cap (not shown) is screwed onto the pedestal part 20. The above-mentioned pressing of the flange 24 is done because it is necessary to prevent the pedestal part 20 from rotating as the cap is screwed, but if the pressing force is too strong, distortion may remain in the flange 24. On the other hand, if the pressing force is weak, the pedestal part 20 will rotate as the cap is screwed on, so the cap may not be screwed on properly. A means for fast screwing was desired.

Furthermore, conventionally, when the cap is screwed onto the pedestal part 20, the lower edge of the cap is connected to the joint part 2 of the pedestal part 20.
When a consumer uses liquid beverages etc. stored in a liquid container equipped with a spout stopper, the cap must be screwed into the cradle each time it is used. 20, the required amount of liquid is allowed to flow out from the liquid container through the spout 25, and after use, the cap is screwed onto the pedestal part 20. It is normal for this cap to be installed and removed several times, which often impairs the resealability of the cap, causing inconveniences such as leakage or intrusion of outside air into the liquid container. Therefore, a structure for easily maintaining the resealability of the cap was desired.

Means for Solving the Problems The present invention has a flange connected to a joint at the lower end of a hollow body having a thread protruding from its outer surface.
A plurality of short outer protrusions in the axial direction are provided on the pedestal portion of the spout stopper of the liquid container whose upper edge of the body serves as a spout, on the outer surface of the body near the joint portion, Furthermore, by configuring the opening edge of the liquid outflow path, which is the inner surface of the joint, to have a plurality of short inner protrusions protruding radially inward, both of the above-mentioned problems can be solved. It is something that

Function: The pedestal part having the above-mentioned structure is fitted and placed on a low circular fitting tool which is protruded and fixed on the mount as shown in Fig. 4, and is fitted with the inner protrusion. By fitting into the groove formed on the circumferential side of the tool, rotation of the pedestal part is prevented in one movement without using any conventional pressing tool, so the cap can be attached to the pedestal part. When screwing on the cap, it is possible to screw the cap with a constant rotational force without causing distortion, and at the end of the screwing process, the inside of the lower edge of the cap frictionally engages with the outer protrusion. Therefore, the resealing of the cap to the pedestal part is reliably performed, and problems such as leakage of the liquid contained in the container and intrusion of outside air into the container do not occur.

Embodiment The embodiment shown in FIGS. 1 to 4 will be described below. In the illustrated embodiment of the pedestal part 11,
Hollow body 2 with threads 8 protruding from the outer surface
A flange 4 is connected to a joint 6 at the lower end of the body, and the upper edge of the body 2 is attached to the pedestal part 11 of a spout stopper of a liquid container, near the joint 6. A plurality of short external protrusions 3 in the axial direction are provided on the outer surface of the body 2 of the
A plurality of short inner protrusions 5, 5 are provided to protrude inward in the radial direction from the opening edge of the liquid outflow path 7, which is the enlarged diameter inner surface of the joint portion 6. .

Effects of the Invention To screw the cap onto the pedestal part 11, as shown in FIG. 4, a mounting base 9 having a fitting tool 10 protrudingly fixed on its upper surface is used.

The fitting tool 10 has a small disc shape into which the lower end of the liquid outflow passage 7 of the pedestal part 11 is fitted, and has an inner protrusion protruding inside the pedestal part 11 on the circumferential side. Recessed grooves 12, 12 into which the numbers 5, 5 are fitted are provided.

By using the mounting base 9, the cap can be screwed onto the pedestal portion 11 quickly and reliably.

That is, the inner protrusions 5, 5 of the pedestal part 11 are connected to the fitting tool 10.
By placing the pedestal part 11 on the mounting base 9 so as to fit into the grooves 12, 12, the rotation of the pedestal part 11 is prevented in one operation without using a pressing tool. . If the cap is screwed onto this pedestal part 11, the pedestal part 11 will not be distorted by the pressing tool at all, and the cap can always be screwed in with a constant rotational force.

Furthermore, when screwing the pedestal part 11 of the cap onto the body part 2, at the end of the screwing process, the inside of the lower edge of the cap and the outer protrusions 3, 3 frictionally engage with each other. Even if the cap is opened and closed without fail, the cap will be resealed reliably, will not loosen, and will not cause defects such as liquid leakage or outside air intrusion.
