In this way, the open / close stopper of the cylindrical spout by the small lid can be made smoother in combination with the small lid opening / closing protruding piece, the collar portion of the small lid, and the inclined surface thereof.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

<Example 1>
FIG. 1 is a cross-sectional view of a state in which a hinge cap showing an embodiment of the present invention is mounted on the mouth of a container, FIG. 2 is a cross-sectional view of a state in which an upper lid is opened, and FIG. is there. In these drawings, a hinge cap (hereinafter simply referred to as a hinge cap) 1 having a small lid that can be opened and closed includes a cap body 6 having a top wall 4 and a side wall 5 to be attached to a mouth 3 of a container 2, and a top wall 7. And an upper lid 10 having a skirt wall 8 connected to the cap body 6 via an outer hinge 9, the upper wall 4 of the cap body 6 being opposite to the outer hinge 9. A cylindrical spout 11 extending in the lateral and upward oblique lateral direction or the horizontal direction is formed, and a small lid 12 for opening and closing the cylindrical spout 11 is provided at an upper end of the cylindrical spout 11 via an inner hinge 13. A small lid opening / closing projecting piece 14 extending inward from the skirt wall 8 is formed on the skirt wall 8 of the upper lid 10 opposite to the outer hinge 9, and is connected to the cylindrical spout 11. Opening and closing plug of small lid 12 , In which so as to interlock with the movement of the small lid closing protruding pieces 14 with the lid actuation of the upper lid 10.

The container 2 may be anything as long as the hinge cap 1 can be attached to the mouth 3 thereof.
A squeeze type is preferably used. As shown in FIG. 1, the hinge cap 1 is attached to the mouth 3 of the container 2 with the side wall 5 of the cap body 6 and the annular inner wall 5 a formed inside the side wall 5 from above. In general, a form that is inserted in a sandwiched manner is used, and in addition to this, a male thread is formed on the outer peripheral surface of the container mouth 3, and the above-described male thread is formed on the inner peripheral surface of the side wall 5 of the cap body 6. Corresponding female threads may be formed and both may be screwed together (not shown).

The cap body 6 has an upwardly protruding raised portion 4a formed on the upper surface wall 4, and the above-described cylindrical spout 11 is formed on the side of the raised portion 4a. And the rising part 4
The upper surface wall 4 around a is recessed, so that even if the contents hang down from the cylindrical spout 11, it does not immediately come out of the outer peripheral wall 4 b so as not to contaminate the user's fingers or around the container 2. I am doing so.

Since the small lid 12 of the present invention is connected to the cylindrical spout 11 of the cap body 3 through the inner hinge 13 so as to be freely opened and closed, it is possible to avoid the situation of falling and becoming contaminated or lost. Therefore, it is excellent in handleability not only for use in ordinary households but also for business use that is frequently used. The small lid 12 is provided with an annular inner wall 12a that fits into the inner periphery of the cylindrical spout 11 and is in a good closed state by sliding contact between the inner periphery of the cylindrical spout 11 and the outer periphery of the annular inner wall 12a. Can be held. Further, a flange 15 is formed on the opposite side of the inner hinge 13 of the small lid 12, and the distal end surface of the flange 15 is formed with an inclined surface 15a extending inward and upward from the outside with the upper lid closed. It has become. On the other hand, a small lid opening / closing protruding piece 14 having flexibility is provided on the inner surface of the lower skirt wall 22 described later of the upper lid 10.

The flange portion 15 and the small lid opening / closing protrusion 14 of the small lid 12 are disposed at positions where they are engaged with each other when the upper lid 10 is opened, and the small lid 12 is opened as the upper lid 10 is opened. Is also performed, small lid 1
In the state where 2 is completely opened, the engagement state between the flange 15 and the small lid opening / closing protruding piece 14 is released.

That is, when the upper lid 10 is opened from the cap body 6, the small lid opening / closing protruding piece 14 first hits the collar portion 15 of the small lid 12 that closes the cylindrical spout 11 and begins to open the small lid 12. That is, the small lid opening / closing protruding piece 14 is engaged with the inclined surface 15a of the flange 15 to completely open the cap. Therefore, the small lid 12 can be opened and closed by the function of only the small lid opening / closing projection piece 14, and in addition, the small lid opening / closing projection piece 14, the flange portion 15 of the small lid 12, and the inclined surface 15 a thereof are combined. Thus, the opening / closing stopper of the cylindrical spout 11 by the small lid 12 can be made smoother.

It should be noted that the small lid opening / closing protrusion 14 may bend slightly as the small lid 12 is opened and closed as can be seen from FIGS. 4 (e) and 4 (f) and FIGS. 5 (k) and 5 (l). It is necessary and preferably has appropriate elasticity. Further, the size of the small lid opening / closing protruding piece 14 needs to have a width and a length that can lead at least the opening / closing operation of the small lid 12.

As described above, the upper lid 10 is connected to the cap body 6 via the outer hinge 9. The upper lid 10 includes the top wall 7 and the skirt wall 8, and the skirt wall 8 is the upper skirt wall 20.
And a connecting wall 21 extending outward from the lower end of the upper skirt wall 20 and a lower skirt wall 22 extending downward from the outer peripheral edge of the connecting wall 21. The small lid opening / closing protruding piece 14 is formed on the lower skirt wall 22, and the inner surface 20 a of the upper skirt wall 20 is formed on the upper lid 10.
The upper skirt wall inner surface 20 a is formed on an inclined surface parallel to the outer surface of the small lid 12. Therefore, when the cap body 6 is closed by the upper lid 10, the upper skirt wall inner surface 20 a of the upper lid 10 hits and presses the cylindrical spout 11 against the small lid 12 being plugged. For this reason, the small lid 12 is unintentionally opened to open the cylindrical spout 11 and the container 2
The contents will not leak. 1 to 3, the portion indicated by 16 is the upper lid 10.
It should be easy to open and close.

The outer hinge 9 is connected to the cap body 6 and the upper lid 10 so as to be openable and closable. After the upper lid 10 is opened from the cap body 6, the upper lid 10 is closed when the container 2 is tilted to pour out the contents. A known snap hinge or the like having a spring property is employed so that the cylindrical spout 11 is turned and closed, and the content is not hindered.
Moreover, it is preferable that the material of the hinge cap 1 of this invention has moderate rigidity and elasticity, and usually polyethylene, polypropylene, etc. are preferably used.

Further, in the plug opening process, in order for the opening of the upper lid 10 and the opening of the small lid 12 to be interlocked, the inner surface side of the small lid opening / closing protruding piece 14 in the upper lid 10 is the flange portion 15 of the small lid 12. Below
When the upper lid 10 is moved in an arc as the lid 10 is opened, the engagement position relationship must be such that the flange 15 of the small lid 12 abuts.
Further, in the plugging process, in order for the closing of the upper lid 10 and the closing of the small lid 12 to be interlocked, the outer surface side of the small lid opening / closing protruding piece 14 in the upper lid 10 is outside the collar portion 15 of the small lid 12. Abut,
In addition, when the upper lid 10 is moved in an arc as the lid is closed, the small lid 12 must be positioned so as to be able to rotate and move toward the cylindrical spout 11 side with the inner hinge 13 as a fulcrum.

In order to smoothly perform the above-described opening / closing plug operation, the inner hinge 13 is integrally formed by being connected to the cylindrical spout 11 and the small lid 12, and the opening / closing plug of the small lid 12 is operated with a snap operation. In addition, it is preferable that the small lid 12 is held in the state of being opened more than the axial direction at the time of opening. Specifically, for example, it is described in Japanese Patent Publication No. 63-17717 or Japanese Patent Publication No. 3-53182. A hinge called a snap type or a flap type is preferably used.

4 and 5, the opening / closing plug of the small lid 12 in the hinge cap 1 configured as described above is provided.
A situation performed in conjunction with the opening / closing lid of the upper lid 10 will be described.
4 is an explanatory diagram of the plug-opening process, FIG. 5 is an explanatory diagram of the plug-closing process, and the reference numerals in FIGS. 4 and 5 are the same as those in FIGS. 1 to 3, but the upper lid 10 and the small lid 12 are opened.

The small lid opening / closing protrusion 14 of the upper lid 10 is located below the flange 15 of the small lid 12 and is open to the upper lid 10. Accordingly, it is positioned so as to abut the collar portion 15 of the small lid 12 when moving in an arc shape. In addition, the inner surface 20a of the upper skirt wall of the top lid 10 presses the cylindrical spout 11 against the small lid 12 being plugged, and the small lid 12 is opened unintentionally so that the contents of the container 2 do not leak.

FIG. 4B shows a state in which the upper lid 10 is opened, and the small lid opening / closing protruding piece 14 is in contact with the flange 15 of the small lid 12. When the upper lid 10 is further opened, as shown in FIG. 4 (c), the small lid opening / closing protruding piece 14 abuts against the flange 15 of the small lid 12 to start opening the small lid 12. The lid opening / closing protruding piece 14 is engaged with the inclined surface 15 a of the flange 15. When the opening operation of the upper lid 10 is further advanced,
The small lid 12 is opened by the action of the small lid opening / closing protruding piece 14 with the inner hinge 13 as a fulcrum, and the small lid 12 proceeds from (d) in FIG. 4 to (e) and (f) in FIG. The lid 12 is completely opened. When the upper lid 10 is further opened, as shown in FIG. 4G, the small lid opening / closing protrusion 14 completely gets over the small lid 12, and the contact state thereof is completely released.

Next, the closing process will be described with reference to FIG.
FIG. 5 (h) shows a state in which the closing of the upper lid 10 is started from the state of FIG. 4 (g) and the small lid opening / closing protruding piece 14 is in contact with the flange 15 of the small lid 12. When the upper lid 10 is further closed, the small lid 12 is closed with the inner hinge 13 as a fulcrum by the action of the small lid opening / closing projection piece 14, as shown in FIGS. 5 (i), (j) and (k). The state progresses sequentially. FIG. 5 ( l ) shows a state where the small lid 12 is closed and the small lid opening / closing protrusion 14 is deformed to get over the small lid 12. 5 (m), the contact state of the small lid opening / closing protruding piece 14 and the small lid 12 is completely eliminated, and the closing of the upper lid 10 is also completely completed, so that the same state as in FIG. 4 (a) is obtained. Therefore, the upper skirt wall inner surface 20a of the upper lid 10 presses the small lid 12, and the contents of the container 2 do not leak.

<Example 2>
FIG. 6 is a cross-sectional view of a state in which a hinge cap showing another embodiment of the present invention is attached to the mouth of the container. In the first embodiment, the upper skirt wall inner surface 20a of the upper lid 10 presses the small lid 12 being closed so that the contents of the container 2 do not leak while the upper lid 10 is closed. However, in the hinge cap 1a, the small lid 12 is placed on the top wall 7a of the upper lid 10a when the upper lid 10a is closed.
