Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dispensing cap for a container formed so that a lid is held in a closed position by a bullet plate.

[Conventional technology]

Conventionally, the pouring cap formed to hold the lid at the closed position with a bullet plate is disclosed in Japanese Patent Publication No. 50-2426 / Sho 58-50.
It is described in Japanese Patent No. 760.

The pouring cap described in Japanese Examined Patent Publication No. 50-2426 is
As shown in FIG. 12, an outer cylinder 61 is provided with bearing pieces 62, 62 and an elastic plate 63 projecting outward, and the bearing pieces 62, 62 are covered with a cover plate.
An elliptic shaft 71, which is provided so as to project to the outside of 70, is rotatably attached, and is formed so that the elastic plate 63 presses and holds the cover plate 70 at the closed position and the open position. is there.

The pouring cap described in Japanese Utility Model Publication No. 58-50760 is
As shown in FIG. 13, a notch hole 65 is formed in the top plate 64 of the outer cylinder body 61, and a lid plate 70 matching the notch hole 65 is rotatably attached to the top plate 64 by pivoting. The cover plate 70 is formed by an elastic plate which is not provided so as to be pressed and held at the closed position and the open position.

[Problems to be solved by the device]

In the conventional pouring cap shown in FIG. 12, since the bearing piece 62 and the like project to the outside of the outer tubular body 61, it is bulky during transportation and the appearance is not good.

In the conventional pouring cap shown in FIG. 13, the opening angle of the cover plate 70 is approximately 90 degrees, and the opening angle is small.

The present invention has been made in view of the above-mentioned matters, and a technical problem is to provide a pouring cap in which a shaft-attached portion does not project outward, a large opening angle can be formed, and which has a good appearance. And

[Means for Solving the Problems]

According to the invention as set forth in claim 1, the top plate 2 having the spout 4 is continuously provided on the top of the elliptical outer cylinder 8 to form the main body 1.
Inside the container, an inner cylinder 12 that can be fitted to the mouth cylinder of the container is provided.
The pair of stanchions 16 is erected at the end of the main body 1 in the major axis direction, and a notch recess 20 is formed in the upper surface between the stanchions 16 and in the upper part of the outer cylinder 8 following the upper surface. A locking portion 22 is provided below the cutout recess 20 and is provided on the upper edge of the outer cylinder 8 facing the cutout recess 20.
The support 31 is integrally formed through the thin hinge 30,
31 is locked to the locking portion 22, a pair of elastic plates 32 are provided upright, an elastic pressure plate 33 is connected to the upper ends of the pair of elastic plates 32, and a lid 40 is provided between the columns 16. The rear portion of the lid 40 is rotatably mounted so that the rear end portion of the lid 40 abuts against the pressure plate 33 so as to be pivotable. The lower surface of the lid 40 closes the spout 4. Was provided as a pouring cap.

According to a second aspect of the present invention, in the pouring cap according to the first aspect, the support 31 is formed separately from the outer tube 8 instead of integrally forming the support 31 on the upper edge of the outer tube 16 via the thin hinge 30. It was formed on the body and used as a pouring cap.

[Action]

In the present invention, when the lid 40 in the closed state is rotated in the opening direction,
The rear end portion of the lid body 40 abuts on the elastic pressure plate 33 and rotates while bending the elastic plate 32 to open the lid. Then, the lid 40 opened
The rear end portion is pressed by the front portion of the compression plate 33 and is pressed in the open state.
