Description

The present invention relates to spout caps.

Conventionally, for example, as shown in Patent Document 1 below, a covering plate is attached to the mouth of a container body in which contents are stored and closes the mouth, and the covering plate is vertically penetrated. Perforated pour caps are known.

Japanese Utility Model Laid-Open No. 59-196445

However, in the conventional pouring cap, when the contents are poured out from the pouring hole, the width of the dropped contents varies greatly depending on whether the container body is slightly tilted or greatly tilted. In addition, there is a risk of miscalculating the amount of the contents to be poured, for example.
That is, even if the container body is slightly tilted and the contents are poured out through the pouring hole, the contents expand when passing through the pouring hole, and the container body is tilted greatly to pour out the contents from the pouring hole. It is difficult to distinguish from the case of pouring out.

The present invention has been made in view of the above-mentioned circumstances. To provide a pouring cap capable of varying the width of objects.

The present invention employs the following means to solve the above problems. That is, the pouring cap of the present invention has a cover plate that closes the mouth of a container body in which contents are accommodated, and the cover plate is formed with a pouring hole penetrating in the vertical direction. is provided with a first hole and a second hole arranged in one direction when viewed from the top and bottom direction, and of the lower surface of the covering plate, at least a portion that continues to the opening peripheral edge of the second hole is the second hole Extending downward toward the two holes, protruding upward on the upper surface of the covering plate, and facing in the other direction orthogonal to the one direction when viewed from the top and bottom direction, sandwiching the first hole A protrusion is provided, and the second hole is spaced apart in the one direction and away from a portion of the opposing protrusion that faces the other opposing protrusion in the other direction. and at least the end of the second hole opposite to the first hole along the one direction is positioned at the same vertical position or above the first hole. ing.

According to the present invention, since a pair of opposing protrusions that protrude upward and sandwich the first hole in the other direction are provided on the upper surface of the cover plate, the contents poured out from the first hole An object is sandwiched between the pair of opposing protrusions. Therefore, when the container body is slightly tilted and the contents are poured out from the first hole, the width of the contents that flow down can be kept narrow.
At least the end of the second hole opposite to the first hole along the one direction is positioned at the same vertical position or above the first hole. When the is slightly tilted, it is possible to suppress the contents in the container body from entering the second hole, and the width of the contents flowing down from the pouring hole can be reliably maintained narrow. .
Since the second hole is separated in the one direction and protrudes in the other direction with respect to the opposing portion of the opposing protrusion, the container body is greatly tilted, and the contents can be transferred not only to the first hole but also to the second hole. When the content is also poured out from the hole, the content rides on the pair of opposing protrusions and rides over the opposing protrusions in the one direction, so that the width of the content flowing down from the pouring hole can be widened. .
As described above, when the content is poured out from the pouring hole, the width of the dropped content can be made different between when the container body is tilted slightly and when the container body is tilted greatly.
Of the lower surface of the cover plate, at least a portion that continues to the opening peripheral edge of the second hole extends downward toward the second hole. Contents can be reliably suppressed from entering the second hole.

An air replacement hole projecting in the covering plate from an end of the second hole opposite to the first hole along the one direction to a side opposite to the first hole along the one direction. may be formed, and at least an end portion of the air replacement hole opposite to the second hole along the one direction may be positioned above the extraction hole.

In this case, since the cover plate is formed with the air replacement holes, when the container body is tilted, the contents can be poured out through the ejection holes while the outside air is introduced into the container body through the air replacement holes. can.
At least the end of the air replacement hole on the side opposite to the second hole along the one direction is positioned above the pouring hole, so that when the container body is tilted, the contents in the container body are displaced. can be suppressed from entering the air replacement hole.

A ridge protruding downward may be formed at least at a connecting portion of the second hole of the opening peripheral edge of the pouring hole on the lower surface of the covering plate, where the second hole is connected to the first hole. .

In this case, in the peripheral edge of the opening of the pouring hole on the lower surface of the covering plate, at least the connecting portion of the second hole with the first hole is formed with a downward projecting ridge. When the container body is slightly tilted, the content in the container body collides with the ridges to prevent the content from entering the second hole, and the content flows down from the pouring hole. The width can be reliably kept narrow.

According to this invention, when the contents are poured out from the pouring hole, the width of the dropped contents can be made different between when the container body is tilted slightly and when the container body is tilted greatly.
