Description

[Detailed Description of the Invention] The present invention relates to a spout stopper with a lid that is attached to the mouth and neck of a liquid storage container and is suitable for use in pouring out liquid.

Conventionally, synthetic resin spout taps have had lids molded integrally with the main body and attached to them, but the main body and lid are connected by a strip plate, etc. Because the lid swings freely, it is necessary to support the lid to prevent it from swinging when dispensing liquid, and to keep the lid closed, a special locking part must be installed between the main body and the lid. It was necessary to set up a

The present invention is a spout tap with a lid made of synthetic resin, which is provided so that the lid can be elastically opened and closed with respect to the main body and held in the open and closed positions.

The illustrated embodiment will be described in detail below. As shown in the open state shown in FIGS. 1 and 2, the main body 1, the lid 2, and the elastic connecting piece 3 are made of a desired synthetic resin material. Molded.

The main body 1 is formed by providing a thread 6 around the inner surface of a peripheral wall 5 that hangs down from the peripheral edge of the top wall 4 so that it can be attached to and removed from the mouth and neck of a liquid storage container (not shown). A flange 7 is provided extending outward from the top wall 4, and a spout 8 is formed at the center of the top wall 4 by a short cylindrical fitting edge 9 that stands upright.

The lid body 2 has a top wall 10 and a peripheral wall 11 hanging from the periphery of the top wall formed into a substantially inverted cup shape so as to correspond to the diameter of the main body 1. A flange 12 is provided to protrude from the center of the top wall 10, and a closing cylinder 13 which is attached to the fitting edge 9 and closes the spout 8 is integrally provided vertically.

As shown in the figure, the main body 1 and the lid 2 have both flanges 7. and 12 are connected by a thin hinge 14 at the tip of a connecting plate formed by separating one part from the other part, and the lid body 2 can be opened and closed with respect to the main body 1 using the hinge 14 as a fulcrum. It is molded as one piece.

The elastic connecting piece 3 connects the main body 1 and the lid 2 and is formed integrally with them, and as shown in the figure, one end 3' is connected to the lower side of the peripheral wall 5 of the main body 1, with the hinge 14 arranged in the front and back. The other end 3'' is connected to the end of the flange 12 of the lid body 2.

More specifically, one end 3' of the hinge 14 is formed by slanting downward from the end of the flange 12 at a position an appropriate distance away from the hinge 14 in the right direction on the drawing paper, and connecting the end 3' to the main body peripheral wall 5. A gap a is provided between the front and rear ends, and the gap a is connected to a gap formed by cutting halfway between the peripheral wall 11 and the flange 12 of the lid body 2. Therefore, the elasticity generating portion 12' of the collar portion 12 forms a part of the elastic linking piece 3.

Also, as shown in FIG. 1, the elastic connecting pieces 3 are provided at the front and rear of the hinge 14, and as shown in the figure, the elastic return force that causes the elastic generating portion 12' of the collar to return to the horizontal position is generated. The lid is kept open.

Furthermore, notches 15, 15 are provided in the flange portion 7 of the main body 1, which faces the elastic connecting pieces 3, 3, and serve as gaps for the elastic connecting pieces 3, 3 when the lid is closed, which will be described later.

In the above configuration, the lid body 2 can be opened and opened with respect to the main body 1.
When the lid is opened as shown in FIGS. 1 and 2, closing is performed by the elastic connecting pieces 3, 3 and the elastic generating portion 12' of the flange 12 that is continuous with the connecting pieces 3, 3.
Since the open state 2 is maintained by act in the direction of stretching itself, and the elastic generating portion 12' of the flange is elastically deformed, and therefore reaches a dead center approximately in the middle of the lid opening/closing process from the open lid position to the closed lid position. From the intermediate position indicated by the two-dot chain line,
If the lid body 2 is slightly swung in the direction of closing the lid, the opening indicated by the solid line in FIG. The lid is kept closed by the elastic connecting pieces 3, 3.
This is done by the elasticity of the elasticity generator 12'.

The present invention has the above-mentioned structure, and the opening/closing of the lid centering around the hinge 14 is configured to be elastically reversed by the elastic action of the elastic generating parts 12', 12' and the elastic connecting pieces 3, 3, and the opening/closing is performed from the girder. At times, the lid does not rattle and can be opened and closed reliably at a predetermined position. In addition, the elastic connecting piece is formed by connecting the end of the elastic generating part and the lower part of the circumferential wall of the spout body, which is located below the end when the lid is closed, through a bent part. Because of this, these elastic generating parts and elastic connecting pieces do not protrude outward from the pouring tap and become a hindrance.
The elasticity generating portion can be easily lengthened by increasing the length of the notch in the flange, and even if this is done, the outer shape of the spout does not change at all, so the elasticity can be adjusted very easily.
