The upper lid 3 is provided with a liquid dripping prevention wall portion 31 that surrounds the spout 30 and projects upward. A neck portion 31b is provided at an intermediate portion in the vertical direction on the outer peripheral surface of the liquid dripping prevention wall portion 31, and by providing the constricted portion 31b, the liquid to the outer peripheral surface of the liquid dripping prevention wall portion 31 is formed. The wraparound of the object is suppressed, and the adhesion of the liquid material to the upper surface of the upper lid 3 is suppressed.

As shown in FIG. 2, the dripping prevention wall portion 31 has an inner surface 31a having a concave curved surface that gradually expands upward, and at the end of pouring. The liquid S that has been drained by the dripping prevention wall portion 31 is once surrounded by the dripping prevention wall portion 31 when the container is placed upright (the dripping prevention wall portion in the closed state). It is adapted to stay in the space surrounded by the inner surface of the plug and the plug) and then return into the spout 31. In the present invention, the volume of the space S surrounded by the liquid dripping prevention wall portion is 0.01 to 0.5 in order to favorably return the drained liquid into the spout.
It is preferably about ml (milliliter).

The upper lid 3 is provided with a recess 32 which can be mounted on the cylindrical wall portion 21, and the lower portion of the inner surface of the recess 32 has a protrusion 33 slightly protruding inward. Are formed. By locking the projection 33 to the locking step 21a of the cylindrical wall 21, the upper lid 3 can be locked at a fixed position.

Inside the outflow hole 4, the support piece 23
The opening 40 is defined so that the formation of the coating film in the opening 40 is less likely to occur.

A peripheral wall 5 which surrounds the outflow hole 4 and projects downward from the lower surface of the support piece 23 is provided at the opening edge of the outflow hole 4. The inner peripheral surface of the peripheral wall 5 is provided on substantially the same plane as the inner peripheral surface of the outflow hole 4, so as to promote the return of the liquid material.

The lower part of the rod-shaped stopper 22 is
A hollow pin 6 is provided so as to project downward from the lower surface of the support piece 23. The outer peripheral surface of the pin 6 has the plug 22
It is formed substantially on the same plane as the outer peripheral surface, and this also promotes the return of the liquid material.

The spout cap 1 is usually the upper lid 3
The peripheral wall portion 21 of the lid body 2 is deeply fitted into the recess 32 of the lid body 22, and the upper end portion of the plug body 22 is attached to the spout 30.
Insert and close the plug. In this state, as shown in FIG.
The inside of the container body 10 can be sealed by screwing the pouring cap 1 into the mouth portion of the container body 10.

When the liquid substance is poured out from the inside of the container body 10, first, the upper lid 3 is pulled upward to lock the upper lid 3 at the locking step portion 21a of the cylindrical wall portion 21. Then, the closure of the spout 30 by the stopper 22 is released. Next, when the body portion (not shown) of the container body 10 is picked up and tilted or pressed, the liquid substance filled in the container body 10 passes through the outflow hole 4 and the tubular wall portion 21 and the It is poured out from the outlet 30. At this time, since the liquid material is widely spread by the inner surface 31a of the liquid drop preventing wall portion 31 of the upper lid and the liquid material is drained well, when the container body 10 is put upright after pouring. Also in this case, the liquid substance does not adhere to the surface of the upper lid 3. In addition, the liquid material that is drained and returned by the dripping prevention wall portion 31 once stays in the space S surrounded by the dripping prevention wall portion 31 and then returns to the inside of the pouring outlet 30. 31
Never overflows. Therefore, the liquid does not drip on the surface of the upper lid 3, the hand is not soiled when the upper lid 3 is operated thereafter, and it is not difficult to pick up when operating the upper lid 3.

When the container body is placed upright, it adheres to the inner peripheral surface of the cylindrical wall portion 21 or the outflow hole 4, the outer peripheral surface of the plug body 22, or the surface of the support piece 23. The liquid substance thus quickly moves to the side of the peripheral wall 5 and the pin 6 and drips to the side of the container body 10, so that it does not stay in the opening 40.

Therefore, even if the container body 10 is shocked when it is laid down, or if the container body 10 is slightly deformed when it is gripped again, no coating is formed on the opening 40 of the outflow hole 4. Therefore, no bubbles are generated from the spout 30. Even if a film is formed in the opening 40, it is quickly returned to the inside of the container body 10 by the peripheral wall 5 and the pin 6 as described above, and therefore, even if the film is inflated by the internal pressure, almost all of the above bubbles are formed. There is no discharge from the spout 31.

As described above, according to the pouring cap 1 according to the present embodiment, the drainage during pouring is good, and the upper lid 3
Since the liquid dripping on the surface can be reliably prevented, it does not hinder the operation of the upper lid unlike the conventional pouring cap. Further, when the liquid material is opened immediately after the liquid material is poured out, the liquid material is returned from the inner peripheral surface of the outflow hole 4 or the cylindrical wall portion 21, the outer peripheral surface of the rod-shaped plug body 22, or the surface of the support piece 23. In addition to being able to promote the formation, it is possible to reliably suppress the formation of the coating film at the opening 40 of the outflow hole 4. Furthermore, even if a film is formed on the opening 40 of the outflow hole 4, it is possible to reliably suppress the formation of bubbles (soap bubbles) from the film.

The pouring cap according to the present invention is not limited to the pouring cap 1 of the above-mentioned embodiment, and its size, shape and the like can be appropriately changed without departing from the object of the present invention. .

For example, in the spout cap 1 of the above-described embodiment, the constricted portion 31b is provided in the vertical middle portion of the outer peripheral surface of the liquid dripping prevention wall portion 31 to improve the liquid drainage property.
The outer wall of the liquid drop prevention wall is shaped to have a trumpet shape or an inverted cone shape, and the outer diameter of the tip is made larger than the outer diameter of the protruding base of the liquid drop prevention wall. By making the angle between the surface and the upper surface acute, it is possible to suppress the liquid material from wrapping around to the outer peripheral surface side and further improve the liquid drainage property.

The dispensing cap 1 of the above embodiment is mounted on the container body 10 by screwing the lid body 2 into the mouth portion of the container body 10. However, the dispensing cap is not mounted on the container body 10. The lid body may be fitted to the container body.
