Then, as shown in FIG. 1 (a), when the opening / closing upper cap (200) is occluded to the mounting cylinder (130) of the cap body (100), the opening / closing upper cap (200) is attached. The outlet hole (131) of the cap body (100) and the opening / closing upper cap (2) shown in FIG.
00), the pouring hole (201) can be gradually reduced by rotating and sliding the pouring hole (201) from the completely open position where the pouring hole (201) is completely continuous as shown in FIG. When further rotated in the right circumferential direction, as shown in FIG. 2B, the inner peripheral wall (2) of the opening / closing upper cap (200) is
The locking ribs (221) of the cap body (10) are
The sliding hole (133) of the mounting cylinder (130) of (0) is brought into contact with and locked to the right end of the sliding contact groove (133), and the pouring hole (201) is completely closed.

Further, as shown in FIG. 5, when the slide hole is rotationally slid toward the left side from the complete opening position shown in FIG. 1 (b), the pouring hole (201) can be made gradually smaller, and the left side is further left. When it is rotated and slid in the circumferential direction, as shown in FIG. 4, the locking ribs (221) of the inner peripheral wall (220) of the opening / closing upper cap (200) are attached to the mounting tube (130) of the cap body (100). The left end of the sliding contact groove (133) is brought into contact and locked, and the pouring hole (201) is completely closed.

If necessary, vertical knurls may be provided on the outer peripheral surface of the outer peripheral wall so that the upper and lower caps for opening and closing can be easily rotated by a finger, and the upper and lower caps for opening and closing may be easily rotated. The opening / closing display of the pouring hole may be provided on both or one side by printing or engraving to facilitate opening / closing of the pouring hole.

Next, in the structure of the cap body of the cap structure according to the second embodiment, a mounting tube on which the upper cap for opening and closing is mounted by biting is erected on the top plate, and the mounting tube is placed at a middle position in the vertical direction. Side is provided with a pouring hole, and the outer peripheral surface facing the pouring hole is provided with a sliding contact groove having a predetermined width from the facing position to the right circumferential direction from the upper end to the lower end. An occlusal groove is provided on the surface, and an occlusal ring with the container is provided on the inner peripheral surface of the lower end of the peripheral wall. An inner sealing ring or a contact sealing ring for sealing the mouth of the container is usually provided on the lower surface of the top plate of the cap body. The structure of the upper cap for opening / closing is similar to that of the first embodiment.

When the opening / closing upper cap is occluded to the mounting tube of the cap body, the opening / closing upper cap is completely continuous with the pouring hole of the cap body and the opening / closing upper cap. By rotating and sliding in the right circumferential direction from the complete opening position, the pouring hole can be gradually reduced, and when further rotating and sliding in the right circumferential direction, the locking ribs on the inner peripheral wall of the opening / closing upper cap are The cap body is brought into contact with the right end of the sliding contact groove of the mounting cylinder and locked, and the pouring hole is completely closed. In addition, the predetermined width of the sliding contact groove provided on the outer peripheral surface of the mounting cylinder of the cap body means that the pouring hole is completely closed when the upper cap for opening and closing is slid in the right circumferential direction. It is the width to do.

[0017]

The cap structure of the present invention, when attached to the mouth of an extruded tube container used for kneaded contents,
The opening / closing of the pouring hole can be done with one touch by rotating the upper cap for opening / closing, and the amount of pouring out the contents can be arbitrarily adjusted according to the size of the rotation angle, which makes the cap structure easy to use during use.

The cap structure of the present invention is mounted on the mouth portion of an extruded tube container, and when the content is poured out by opening the pouring hole, the pouring direction of the content is the extruded tube container. Since it is bent by 90 degrees with respect to the pouring direction, the contents can be poured out without bending the hand to an unnatural shape on the toothbrush in the case of toothpaste, for example.

Further, the extruded tube container having the cap structure of the present invention attached to the mouth can be exhibited in a completely inverted state at a store, and it can save space and improve the appeal of the product. .
