BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap structure for closing a container and discharging contents.

[0002]

2. Description of the Related Art A cap comprising an inner plug having a spout and an upper lid for covering the inner plug and closing the spout is attached to a mouthpiece portion of a container for accommodating a liquid content . This
In such a cap , the upper lid is detachably attached to the mouthpiece. For this reason, it is necessary to remove the upper lid at the time of use, and to attach the upper lid after use. At this time, there is a disadvantage that it is difficult to attach the upper lid with the hand after taking out the contents such as the hair washes. On the other hand, there is a possibility that the removed upper lid may be lost.

Therefore, conventionally, in order to simplify the work of attaching and detaching the upper lid, the inner plug and the upper lid are integrated via a hinge or hinge, and the inner plug and the upper lid are fitted / unfitted. There is a free cap. When the cap is used, the upper lid is detached from the inner plug, and the upper lid is pivoted about a hinge or hinge. After use, the upper lid is turned in the opposite direction and fitted on the inner lid. According to this cap,
The upper lid can be detached with one touch, and the upper lid is not lost. By the way, when pouring out the liquid content, it is preferable that the pouring port protrudes from the upper surface of the inner lid. This is because, when the spout and the upper surface of the inner lid are at the same height, the liquid discharged from the spout passes over the upper surface of the inner lid and causes dripping. The above-mentioned hinge or hinge-structured cap has a drawback that the spout cannot be protruded too much to rotate the upper lid. For this reason, the contents adhere to the vicinity of the spout of the inner plug, and it is not only dirty,
It is not preferable from the viewpoint of hygiene, for example, the content dries and adheres after a lapse of time.

[0004] As a device for solving the above problems, a pouring cap disclosed in Japanese Utility Model Laid-Open No. 3-108656 is disclosed. The structure of the pouring cap is shown in FIGS. In the dispensing cap of the present invention, the cap body 11 and the lid 12 are connected via a hinge 13, and one end of a flexible nozzle 14 is connected to the outlet of the cap body 11.
Further, a nozzle holder 15 for fixing the nozzle 14 is formed on the back surface of the lid 12, and the rear lid 12 with the nozzle 14 fixed to the nozzle holder 15 during storage is rotated around the hinge 13 to the cap body 11. Fit. At this time, the nozzle 14 is bent and housed between the lid 12 and the cap body 11. In use, the lid 12 is detached from the cap body 11 and the lid 12 is rotated about the hinge 13. Then, the nozzle 14 is removed from the nozzle holder 15 of the lid 12, and the contents are extracted. According to the present invention, the fitting and unfitting of the lid 12 can be performed with one touch, and the lid 12 is not lost. Also, nozzle 1
The protrusion of the cap 4 above the cap body 11 has an advantage that the cap body is less likely to be contaminated by dripping during use.

In Japanese Utility Model Application No. 57-152630 (Japanese Utility Model Application Laid-Open No. 60-39627), a straw is inserted into one end of a water bottle main body, and the other end is protruded outside the water bottle main body. Provide a lid that covers the straw protruding part while holding it in the standing posture at all times, press the straw inside the lid while bending the protruding part into the inside of the lid, and release the pushing to protrude the straw out of the lid. There is provided an apparatus in which the position to be made can be selected by rotating the lid.

However, in the former case, the nozzle is removed from the nozzle holder of the lid at the time of use, and it takes time and effort to fix the nozzle to the nozzle holder of the lid after use, and the operation is complicated. In the latter, since the straw is pushed into the lid, the material thereof is extremely limited, and in order to smoothly guide the straw, it is necessary to precisely specify the size and shape of the window from which the straw projects. SUMMARY OF THE INVENTION It is an object of the present invention to provide a cap which allows a through-hole of a nozzle to be opened and closed by a valve portion, and at the same time, can easily form a guide portion for smoothly moving the nozzle.

Accordingly, the present invention simplifies the time and effort required at the time of use and at the end of use to improve operability,
It is an object to provide a sanitary cap that prevents dripping.

[0007]

The nozzle is formed in an upright state by an elastic body, and returns to the upright state when the nozzle is no longer held by the guide portion. The guide portion may be formed in a semi-cylindrical shape in which a portion in contact with the valve portion has a cylindrical shape, and a distal end side of the guide portion has an open lower surface. Since the valve body is provided with the guide part and the valve part integrally, if this is fitted into the lid side through hole, the valve part and the guide part can be easily installed.

The cover side through hole may be provided not only on the top plate of the cover but also on the side wall of the cover, and as long as the distance from the inner cover side through hole changes by rotation of the cover, It may be provided at a position.

[0011]

The cap of the present invention is in a state where the nozzle is bent and accommodated between the lid and the inner lid when not in use. That is, the lid is located at a position where the lid-side through-hole and the middle lid-side through-hole are shifted. Then, when the lid is rotated and the lid-side through-hole and the middle lid-side through-hole approach each other, the nozzle is guided by the guide portion, and moves from the bent state to the upright state while moving toward the lid-side through-hole. . When the positions of the lid-side through-hole and the middle lid-side through-hole overlap, the nozzle reaches the lid-side through-hole and stands upright, and the tip of the nozzle pushes the valve portion open and protrudes above the lid.

Here, the user can pour out the contents by tilting the container or the like. After the contents are poured out, the user rotates the lid in the direction opposite to the above. With this, the position of the lid side through-hole and the inner lid side through hole gradually shifts, and the nozzle bends between the lid and the inner lid, and at the same time, the nozzle moves from the lid side through hole to the middle of the lid. It is drawn between the lid. When the tip of the nozzle is completely housed, the user stops rotating the lid.

The cover rotates only between the position where the nozzle is completely accommodated and the position where the nozzle protrudes (the position where the position of the cover side through hole and the position of the middle cover side through hole coincide). It may be.
