きる便利さから各種容器に多用されている。"Problems to be solved by conventional techniques and devices" As is well known, this type of cap has a pouring hole formed in the top wall and is attached to the mouth of the container. A lid member having a bar plug for opening and closing is attached, the rear side of the lid member is separated into an inverted L-shaped strip, and the upper and lower ends of the strip are joined to the lid member and the upper part of the cap body peripheral wall with thin hinges. When the lid members on both sides of the strip are joined to the rear of the top wall by a thin hinge to be integrated with the cap body, and the lid member is opened rearward against the elasticity of the strip, the thin hinge at the upper end of the strip is closed. By flipping the pair of thin hinges for coupling to the opposite side, the tension of the band-shaped part can hold the lid member in an open state stably, and various containers can be opened and closed with a single touch. Is often used in.

は短く抑えられていた。By the way, with this kind of cap, for example,
It is widely known that the nozzle protrudes upward from the periphery of the spout hole to facilitate pouring like the cap described in Japanese Patent Publication No. 51, and this spout nozzle has a nozzle effect as the projection length increases. However, when the protruding length is increased, the lid member is inevitably a large deep one. Further, since the lid member is rotated and opened and closed with a pair of thin hinges at the rear as fulcrums, the rod plug is inserted into the pouring nozzle at a slight angle, and this cap has a high frequency of thin hinges. Since it is made of polypropylene resin, which has excellent refraction and durability and is hard to deform so that it can withstand refraction, it is required that the ejection nozzle be as small as possible from the top of the seal. The protruding length of the ejection nozzle was kept short.

性反転形キャップを得るにある。According to the present invention, the top wall front part of the cap body is formed as an inclined surface having a low front edge, and the pouring nozzle 4 is erected from the front part of the inclined surface. Therefore, on the pouring side, the pouring nozzle is made to protrude largely upward. This is to obtain an elastic reversal type cap that is capable of obtaining a nozzle effect equivalent to that of the above case.

た。"Means for Solving the Problems" The front portion of the top wall 3 is formed as an inclined surface having a low front edge, and the cap body 1 in which the pouring nozzle 4 is erected from the front portion of the inclined surface and a probing dish-shaped hanging body are provided. The peripheral wall 5 has a shape corresponding to the top of the cap body 1, and a rod plug 7 inserted into the pouring nozzle 4 is hung from the back surface of the top plate 6 so as to be opened and closed on the upper surface of the top wall 3. It is composed of a lid member 2, and the lid member 2 and the cap body 1 are joined to each other at their rear portions via a three-point hinge mechanism.

It can be regarded as equivalent to a case in which the flat plate-like portion at the rear portion of the top wall 3 is largely erected, and the nozzle effect is large and easy to pour.

In an elastic inversion type cap with a point hinge mechanism, the front portion of the top wall 3 of the cap body 1 on which the pouring nozzle 4 is erected is a front surface having a low inclined surface, and the pouring nozzle 4 is placed upward on the pouring side. It is characterized in that the same nozzle effect as when it is largely projected is obtained.

部10上部に内嵌される。In the cap body 1, the front portion of the top wall 3 is an inclined surface having a low front edge,
A pouring nozzle 4 is erected from the front part of the inclined surface. The height of the opening of the pouring nozzle 4 is the same as before, but the substantial height on the pouring side is large due to the lowering of the standing base. This cap body 1 has a thread groove formed on the inner peripheral surface of the peripheral wall 8, and is screwed and attached to the outer surface of the mouth / neck portion 10 of the container body 9 by the thread groove. Reference numeral 11 denotes a cylindrical plug vertically provided from the back surface of the top wall 3, which is fitted in the upper portion of the mouth / neck portion 10.

している。The lid member 2 is in the shape of a flat dish, and the rod stopper 7 is hung from the back surface of the top plate 6. Further, the hanging peripheral wall 5 corresponds to the top of the cap body 1 by increasing the hanging length of the front half. The knob 12 for opening and closing is attached to the front surface of the hanging peripheral wall 5.

保持される。The lid member 2 is integrally formed from the cap body 1 and a resin material having high rigidity such as polypropylene by a well-known three-point hinge mechanism. That is, the rear side of the lid member 2 is inverted L
In the shape of a strip, and the strip 13 is extended downward and the upper and lower ends are thin hinges 14 and 15 with the top plate 6 and the cap body peripheral wall 8.
The lid member 2 on both sides of the strip 13 is joined to the upper portion, and the hinges 16 and 16 join the rear portions of the lid member 2 to the rear portion of the top wall 3. Therefore,
In the state shown in FIG. 1, the closed state is maintained by the elasticity of the strip 13 and the insertion engagement of the rod plug 7 with the nozzle 4,
In the figure, the thin hinge 14 is a thin hinge for a pair of fulcrums.
The closed state is maintained by reversing to the rear side from 16,16.

利点がある。[Advantage of Device] As described above, in the present invention, the front portion of the top wall 3 of the cap body is an inclined surface having a low front edge, and the pouring nozzle 4 is erected from the front portion of the inclined surface. Even if the height of the opening of the nozzle is the same as before, the substantial height on the pouring side is large, and therefore the nozzle effect is large, so that it is easy to pour, and there is the convenience that the dirt of the pouring nozzle 4 can be easily wiped off. . Further, as described above, since the height of the opening of the pouring nozzle 4 can be made the same as before, there is an advantage that a resin material having high rigidity can be formed from a material, and the refraction and durability of the thin hinge can be maintained. .
