The shielding member C is integrally formed with the cap B so as to be vertically hung on the lower surface of the upper wall 5 of the cap base B1, but as shown in FIG. A groove is engraved on the boundary of, so that a thin connecting portion 18 is formed. After molding, the shielding plate 19 is bent at the connecting portion 18 and turned until it is substantially horizontal, and the edge 19a rides over the locking piece 20 and is locked to the locking surface 20a, as shown in FIGS. It is formed in a good shielding state.

Next, the operation and effect of the liquid discharging container of the present invention will be described. After the container A is filled with the content liquid, the liquid pouring container is covered with a cap B with the shielding plate 19 in a shielded state, packaged, and shipped. When using the liquid pouring container, the opening / closing lid B2 is opened, the mouth 1 of the container A is directed in a desired direction, and the body 2 is pressed, or the liquid is poured by the liquid pressure due to the weight of the liquid. Let out.

When the opened container A is tilted at the time of pouring, the shielding plate 19 is actuated by the water hammer action of the content liquid.
Is applied to the shield plate 19, but the shielding plate 19 is provided with a restoring force for returning to the state at the time of molding, and has elasticity. , And is maintained in a substantially shielded state. Therefore, when the container A is tilted, the content liquid does not fly out temporarily.

As shown in FIG. 5, when the container opening 1 is directed in a desired direction and the body 2 is pressed, the shielding plate 19 is rotated by liquid pressure against its restoring force to form a flow path. , The contents can be poured out. When the pressing of the body 2 is released, the body 2 is restored and the pressure inside the container A becomes low, air flows in from the pouring hole 12 and the shielding plate 19 is closed, but the side plate 17 and the shielding plate 19 are closed. The air flows into the body 2 through the gap s between the edge 19a and the next press and discharge.

Next, an embodiment of the shielding member C will be described. In the above-described embodiment, the shielding member is formed in a rectangular shape including four side plates, and the shielding plate is formed in a rectangular shape. However, the shielding member and the shielding plate may be circular, elliptical, and polygonal.

Is a cylinder suspended from the lower surface of the upper wall 5a. Cylinder 30
At a predetermined location, as a thin wall, via a connecting portion 31,
A circular shielding plate 32 is continuously provided, and a locking piece 33 is protrudingly provided on the opposite side. A notch 34 is provided at a position corresponding to the locking piece 33 of the shielding plate 32, so that a gap s is formed between the notch 34 and the inner periphery of the cylinder 30. The function and effect of the shielding plate 32 are the same as those of the above-described embodiment.

In the second embodiment, as shown in FIG. 7, a hexagonal shielding plate is used. In the figure, reference numeral 40 denotes a hexagonal rectangular tube vertically provided on the lower surface of the upper wall 5a of the cap base B1. One side plate 41 of the rectangular tube 40 has a thin connecting portion 4
A hexagonal shielding plate 43 is continuously provided through the intermediary 2, and a locking piece 45 is projected from a side plate 44 facing the side plate 41. A side 43a of the shielding plate 43 corresponding to the side plate 44 forms a gap s between the side plate 44 and the side 43a. The operation and effect of the shielding plate of this embodiment are the same as those of the above embodiment.

Next, a third embodiment in which the structure of the shielding plate is changed will be described with reference to FIG. In the figure, 50
Is a quadrangular rectangular tube vertically provided from the lower surface of the upper wall 5a of the cap base body B1, and includes four side plates 51, 52, 53a and b. At the lower end of the side plate 51, a thin connecting portion 54 is provided.
, A rectangular shielding plate 55 is continuously provided.

A plurality of locking pieces 56 projecting upward from the edge 55a are provided at the leading edge of the shielding plate 55. When the shielding plate 55 is positioned horizontally with respect to the opposing side plate 52, the tip of the locking piece 56 is
At a predetermined distance from the lower end of the cover 55 with a resilient force to prevent the shielding plate 55 from rotating.

The shielding member C of this embodiment is also formed by integral molding with the cap base, and after molding, the shielding plate 5 is formed.
5 is bent at the connecting portion 54 and rotated until it becomes a horizontal state, and the tip of the locking piece 56 is pushed above the lower end of the side plate 53.

Next, the function and effect will be described. When the opened container A is tilted, a shocking hydraulic pressure is applied to the shielding plate 55 by the water hammer action.
Since the resilient force of the locking piece 56 acts between 6 and the side plate 52, the shielding plate 55 does not move. Therefore, the content liquid does not flow out.

When the body 2 is pressed, the shielding plate 55 can be rotated against the elasticity of the locking piece 56. Torso 2
Is released, the pressure inside the container becomes low, and the air that has flowed in from the pouring hole flows into the body from between the side plate 52 and the edge 55 a of the shielding plate 55.

In the above embodiment, the cylinder is a square prism, but the cylinder may be a hexagonal prism or a cylinder as shown in FIG.

Next, a second embodiment will be described. In the present embodiment, a shielding member is integrally formed with an inner plug provided with an ejection tube. In FIG. 9, Aa is a container, Ba is a cap, D is an inner plug, and Ca is a shielding member integrally formed inside the inner plug.

I have. A pouring cylinder 68 having a pouring hole 67 is provided upright on the upper wall 64, and a sealing ring that fits on the inner periphery of the mouth portion 60 and seals the inside of the container Aa on the lower surface of the upper wall 64. 69 are erected,
A shielding member Ca is vertically provided on the inside.

As in the first embodiment, the shielding member Ca is provided with a rectangular tube 70 suspended from the lower surface of the upper wall 64, and is connected to one side plate 71 via a thin connecting portion 72. , And a shielding plate 73 are continuously provided. The side plate 74 facing the side plate 71 is provided with a locking piece 75 protruding therefrom.

The cap Ba has a top wall 76 and a side peripheral wall 77, and the lower surface of the top wall 76 has a pouring hole 6 when the lid is closed.
A plug 78 for sealing the container 7 is vertically provided, and a screw 79 screwed to the screw 63 of the container opening 60 is provided on the inner periphery of the side peripheral wall 77.
Is screwed.

The operation and effect of this embodiment can provide the same operation and effect as those of the first embodiment.
