Further, the fitting projection 50 has a reduced projection 51 that extends from at least the lower side of the cutouts 13 on both sides to the lower side of the standing wall 11 leaving a central portion 50a of the width of the window w on the rear side.
It should be noted that the fitting ridge 50 may be reduced ridges 51 continuous from both sides without leaving the central portion 50a on the back side, and the fitting ridges 50 on the hinge portion side (back side) may be the reduced ridges 51. You can delete it without doing anything.

In the upper cap Cb, as in the second embodiment, the side peripheral wall 19 on the rear side is notched from both sides as hinge cutouts 39, and a pair of thin band portions 37 forming a hinge portion Db, which will be described later, are continuously formed. It is
Further, between the thin band portions 37, a convex portion 52 is formed to be inserted into the window portion w of the hinge portion Db when the lid is opened.
As shown in FIG. 13, the convex portion 52 extends so that the lower end forms a small gap (for example, about 0.2 mm) with the bottom surface 53 of the window portion w.

The hinge portion Db is formed as a thin integrated hinge extending from the upper end of the inner peripheral side of the upright wall 11 of the lower cap Bb to the inner peripheral side of the side peripheral wall 19 on the back side of the upper cap Cb, and has a rectangular shape at the center of the hinge portion Db. A pair of thin strips 37 are formed in the vertical direction across the window w formed in the upper and lower sides, and a groove 38 is formed in the circumferential direction at the intermediate portion of the thin strips 37 in the vertical direction in order to provide an edge for bending. formed respectively.

As in the second embodiment, the breaking portion Ea has knob portions 41 formed at two circumferential ends, and an upper side 44 of the breaking portion Ea forms an upper gap portion between the inclined lower surface 19b of the upper cap Cb. g1 is formed, and the upper edge 44 is connected only to the front lower surface of the upper cap Cb by a thin upper weakened portion 42 that can be broken.
Similarly, the lower edge 45 of the fractured portion Ea has a lower gap g2 formed between the inclined lower surface 19b of the upper cap Cb and the corresponding lower cap upper end 10, and the lower cap upper end of the lower cap Bb on the front half circumference of the lower cap Bb. 10 is connected by a breakable thin-walled lower weakened portion 43 .

Further, the breakage portion Ea is connected to the inclined lower surface 19b of the upper cap Cb by a pair of breakable upper bridge portions 46 at the upper side 44 on the knob portion 41 side of the upper gap portion g1. On the knob 41 side, the lower edge 45 is connected to the lower cap upper end 10 of the lower cap Bb by a pair of breakable lower bridges 47 .
A pair of upper spacer projections 48 adjacent to the upper end surface of the knob portion 41 of the breaking portion Ea are formed at the connecting portion between the rear lower surface 19a and the inclined lower surface 19b of the upper cap Cb. A pair of lower spacer protrusions 49 are formed at the rear side end of the upper end 10 of the lower cap so as to be adjacent to the lower end surface of the knob 41 of the breaking portion Ea.

Next, the mode of use and effects of this embodiment will be described.
As shown in FIGS. 11 and 12, the hinge cap of this embodiment is manufactured by integral molding with the lid closed as in the case of the first embodiment.

Next, in order to attach the hinge cap of this embodiment to the container main body A by tapping, the lower cap lower end 9 of the lower cap Bb constituting the hinge cap is attached to the opening 1 of the container main body A filled with the contents. When the top wall 18 of the upper cap C of the hinge cap is pressed against the upper surface, the fitting projection 50 of the outer cylinder wall 8 engages the lid engaging portion 3 of the opening 1 and the locking projection 4. By successively getting over and finally engaging with the locking projection 4, the attachment of the hinge cap to the container main body A is completed as shown in FIG. 11(a).

In the hinge cap of this embodiment, since the rear side of the fitting projection 50 is formed as a reduced projection 51, the outer cylinder wall 8 near the reduction projection 51 is formed such that the fitting projection 50 is not close to the opening 1 at the time of plugging. A large load in the vertical direction is not applied when getting over the lid engaging part 3 and the locking projection 4, and the upright wall 11 above the outer cylinder wall 8 and the hinge part Db are prevented from buckling deformation at the time of plugging. can.

Further, since the lower end of the convex portion 52 of the upper cap Cb is close to the bottom surface 53 of the window portion w with a slight gap, when the top wall 18 of the upper cap Cb of the hinge cap is pressed during plugging, , the lower end of the convex portion 52 abuts against the bottom surface 53 of the window portion w, thereby preventing the upper cap Cb from sinking into the lower cap Bb.
Furthermore, since the upper spacer convex portion 48 and the lower spacer convex portion 49 are formed from the upper cap Cb and the lower cap Bb so as to face the upper end surface and the lower end surface of the knob portion 41, the knob portion 41 can be easily removed during plugging. 41 can be prevented from expanding radially outward.

As described above, in this embodiment, when the hinge cap is capped on the container body A, the load on the thin hinge portion Db is reduced, thereby preventing the hinge portion Db from being damaged, and the container of the hinge cap. Mounting to the main body A can be stably performed.
Other effects are the same as those of the second embodiment.

The hinge cap of the present invention is a hinge cap that can be molded with the lower cap and the upper cap closed, in which the knob portion protrudes radially outward when cutting off the fractured portion connecting the lower cap and the upper cap. Therefore, it can be widely used as a hinge cap used for food and drink containers, etc., where it is necessary to visually confirm tampering.
