Container closure with outflow tube
First Claim
1. A container closure, comprising:
- a closure body adapted to be mounted on a mouth-and-neck portion of a container;
an outflow tube having a penetrating outflow path; and
an outer cap, and wherein;
the closure body has a main wall covering a top surface of the mouth-and-neck portion of the container when the closure body is mounted on the mouth-and-neck portion of the container, and an outflow hole is disposed in the main wall;
the outflow tube is pivotably mounted on an upper surface of the main wall of the closure body, when the closure body is mounted on the mouth-and-neck portion of the container and the outflow tube is located at an outflow position at which the outflow tube extends upward from the outflow hole of the main wall, the penetrating outflow path communicates with the interior of the container via the outflow hole; and
when the outflow tube is toppled to a closed position, the penetrating outflow path is cut off from communication with the outflow hole;
the outer cap is mounted on the closure body pivotably between a closed position and an open position;
when at the closed position, the outer cap covers the main wall of the closure body and the outflow tube; and
when at the open position, the outer cap exposes the main wall of the closure body and the outflow tube;
when the outer cap is pivoted from the closed position toward the open position, the outer cap contacts the outflow tube located at the closed position to erect the outflow tube from the closed position to the outflow position, and when the outer cap is then further pivoted toward the open position the outer cap is separated from the outflow tube and brought to the open position;
when the outer cap is pivoted from the open position toward the closed position, the outer cap contacts the outflow tube located at the outflow position to topple the outflow tube from the outflow position to the closed position, and the outer cap is also brought to the closed position;
a closed position restricting piece is disposed on the main wall of the closure body;
when a pressing force of at least a predetermined value is exerted on the closed position restricting piece via the outflow tube as the outflow tube is toppled and contacted with the closed position restricting piece, the closed position restricting piece is tilted and the outflow tube is further toppled; and
when the pressing force via the outflow tube is released from the closed position restricting piece, the closed position restricting piece is elastically restored.

Abstract
A container closure is composed of a closure body, an outflow tube, and an outer cap. The outflow tube is pivotably mounted on the closure body. The outer cap is mounted on the closure body pivotably between a closed position and an open position. When the outer cap is pivoted from the closed position toward the open position, the outer cap contacts the outflow tube located at the closed position to erect the outflow tube from the closed position to the outflow position. The outer cap is then separated from the outflow tube and brought to the open position. When the outer cap is pivoted from the open position toward the closed position, the outer cap contacts the outflow tube located at the outflow position to tilt the outflow tube from the outflow position to the closed position, and the outer cap is also brought to the closed position.

1. A container closure, comprising:
-
a closure body adapted to be mounted on a mouth-and-neck portion of a container;
an outflow tube having a penetrating outflow path; and

a closed position restricting piece is disposed on the main wall of the closure body;
when a pressing force of at least a predetermined value is exerted on the closed position restricting piece via the outflow tube as the outflow tube is toppled and contacted with the closed position restricting piece, the closed position restricting piece is tilted and the outflow tube is further toppled; and
when the pressing force via the outflow tube is released from the closed position restricting piece, the closed position restricting piece is elastically restored. - View Dependent Claims (2, 3, 6, 7)
