DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cap with a reversing hinge, and more specifically, reversing a container to be attached to the mouth tube of a container for containing seasonings, cosmetics, chemicals, etc. Regarding a hinged cap.

(Prior Art) Conventionally, a cap in which the lid body is integrally formed with the cap body is well known so that the lid body removed when pouring out the contents in the container is not dropped or lost. As described above, the lid body and the cap body are connected to each other through the L-shaped bullet plate in order to facilitate the production, that is, the molding. Such a cap is generally called a cap with an inverted hinge, which is disclosed in, for example, Japanese Utility Model Laid-Open No. 61-166940.

The conventional cap disclosed in Japanese Utility Model Laid-Open No. 61-166940 is a cap composed of a top wall having a spout 4 as shown in FIG. 8 and a cylindrical portion 2 suspended from the peripheral edge thereof. The main body 1, an L-shaped bullet plate 10 provided on a part of the tubular portion 2 of the cap main body 1 via a hinge portion 11, and a lid connected to the L-shaped bullet plate 10 via a hinge portion 15. It is basically configured to include the body 20.

In this conventional cap, a locking projection 30 is provided upright on the outer edge of the top wall of the cap body 1 on the L-shaped bullet plate side, while the L-shaped bullet plate 10 is bent by a hinge portion 11 to form a cylinder. An opening is formed at a position where the above-mentioned locking projection 30 can be fitted when it comes into close contact with the wall surface of the shaped portion 2, and the locking projection 30 can be locked at the inner edge of this opening. A locking projection 12 is formed.

In the conventional cap configured as described above, the L-shaped bullet plate 10 is opened with respect to the tubular portion 2 of the cap body 1 as shown in FIG. Is also open to the L-shaped bullet plate 10. To make this cap usable from this state, first set the lid
The L-shaped bullet plate 10 is hinged so that 20 is pulled forward.
Rotate at 11 so that the locking projection 30 passes through the opening of the L-shaped bullet plate 10 so that the tip end side of the L-shaped bullet plate 10 overlaps with the top wall and the locking projection 12 is used as the locking projection 30. Lock as shown in FIG.

From this state, the lid body 20 is further rotated by the hinge portion 15 so as to overlap with the top wall, and the stopper portion 22 projecting inward of the lid body 20 is press-fitted into the spout 4 to close the lid state. Can be Then, when opening the lid body 20 for pouring out the contents, if the outer edge portion of the lid body 20 on the side opposite to the hinge portion 15 is pushed up, the lid body 20 rotates 90 ° or more with the hinge portion 15 as a fulcrum. The capping portion 22 can be pulled out from the pouring port 4 and the contents can be poured out.

At this time, the L-shaped bullet plate 10 does not move at all and the locking projection piece
The locked state between 12 and the locking projection 30 remains unchanged. Next, when closing the lid 20, if the lid 20 is inverted again, the original closed state is restored and the spout 4 can be closed.

As is clear from this, the L-shaped bullet plate 10 is provided as a means for avoiding the molding difficulty due to the mold construction when integrally molding this type of cap.

Further, as another conventional example, a device disclosed in Japanese Utility Model Laid-Open No. 63-158859 is known. The cap with a reversible hinge described in this publication is shown in FIGS. 10 and 11, and the cap body 1 serves as a means for fixing an L-shaped bullet plate 10 provided to the same effect as the conventional cap described above. A T-shaped groove in cross section is formed on the circumferential surface of the cylindrical part of the L-shaped bullet plate 10.
A pair of locking projections 12 that are press-fitted into a locking portion 31 formed of the groove is formed on the inner surface of the.

In order to make such a conventional cap with a reversible hinge usable after being molded, the L-shaped bullet plate 10 is attached to the hinge portion 11.
And the rear surface of the cap body 1 is strongly pressed toward the center of the tubular portion 2 of the cap body 1 to lock the pair of locking projections 12 into the locking portion 31.
Press-fit into. Next, using the hinge portion 15 as a fulcrum, the lid body
The lid 20 can be closed by rotating 20 to insert the stopper 22 into the spout 4. After that, when pouring out the contents, the lid 20 is carried out in exactly the same manner as in the conventional example described above, and the L-shaped bullet plate 10 is also left in this state.

(Problems to be Solved by the Invention) However, in the conventional cap with a reversible hinge shown in FIGS. 8 and 9, since the locking projection 30 is projected forward, L-shaped bullet plate 10 locking protrusion
In order to lock 12, the L-shaped bullet plate 10 cannot be locked unless the L-shaped bullet plate 10 is pulled out forward, and there is a problem that the locking operation is troublesome.

On the other hand, in the conventional cap with a reversing hinge shown in FIGS. 10 and 11, a groove having a T-shaped cross section is firmly formed in a vertically long shape so that the engaged locking projection 12 does not come off from the locking portion 31. Therefore, in order to engage the locking projection 12 with the locking portion 31, it has to be strongly pressed with a considerable force, which is also very troublesome.

As one means for solving such a problem, a pair of small locking struts are erected on the top wall forming the spout, and a pair of small hook-shaped flexible hooks are formed on the inner surface of the L-shaped bullet plate. It has been proposed to form locking projections and insert the pair of locking projections from the inside of the pair of locking posts to lock them. According to this, the locking projection is certainly locked to the locking columns, in other words, the pressing force between the columns does not require much force, and the operation of fixing the L-shaped bullet plate becomes easy. However, this time, since the flexibility of the locking projection is improved, a new problem arises in that the locking projection easily comes off due to the operating force when opening the lid.

The object of the present invention is to solve such a problem, and to make the engaging operation of the locking projection formed on the L-shaped bullet plate to the cap body easy and reliable, but to release it after locking. Providing a cap with a difficult reversible hinge.

A pair of locking posts 5 standing on the outer edge of the upper surface of 3
And a pressing piece 6 that is laid over the upper part of the locking column 5.
And an L-shaped bullet plate 10 whose lower end is integrally connected to the outer periphery of the tubular portion 2 constituting the cap body 1 via a hinge portion 11.
And a pair of locking projections 12 projectingly formed on the inner surface of the L-shaped bullet plate 10, and a lid body 20 connected to the upper end of the L-shaped bullet plate 10 via a hinge portion 15. And an L-shaped bullet plate that is formed inside the lid body 20 and closes the spout 4 of the cap body 1 when the lid body is attached to the cap body. It is characterized in that the locking projections 12 projectingly provided on the inner surface of 10 are inserted into the inside of the locking columns 5 and locked.

(Operation) According to the inversion hinged cap of the present invention, the L-shaped bullet plate 10
The pair of locking projections 12 provided on the inner surfaces of the two are inserted into the inner portions of the pair of locking columns 5 provided on the outer edge of the upper surface of the top wall 3 while being bent. After the locking projections 12 are inserted between the pair of locking posts 5 and locked therein, the locking projections 12 are provided so as to straddle the locking posts 6.
The upper part is pressed by. for that reason,
It is difficult for the locking projection 12 to easily separate from the locking columns 5, 5.

When the tip of the closed lid body 20 is pushed up, the lid body 20 first pushes up the hinge portion 15 upward to make the L-shaped bullet plate.
While the tip end of 10 is extended so as to be bent back at the L-shaped bent portion, the hinge portion 15 is rotated about 90 ° about the fulcrum, and when the dead point is exceeded, the hinge portion 15 is pulled by the L-shaped bullet plate 10. The lid 20 is automatically turned over again so that the contents can be extracted from the spout 4.

Then, after pouring out the contents, if the container is erected and the lid 20 is turned upside down with the hinge portion 15 as a fulcrum, the lid 20 returns to its original position and the stopper portion 22 closes the spout 4. .
