Japanese Utility Model Application Publication No. 59-196445

However, with the conventional dispensing cap, when pouring the contents from the pouring hole, the width of the contents flowing down does not change significantly whether the container body is tilted slightly or significantly, which could lead to misjudging the amount of contents being poured out, for example.
In other words, even if the container body is tilted slightly to pour the contents through the pouring hole, the contents will expand when they pass through the pouring hole, making it difficult to distinguish this from when the container body is tilted significantly to pour the contents through the pouring hole.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide a pouring cap that can change the width of the contents that flow down when pouring the contents from the pouring hole depending on whether the container body is tilted slightly or greatly.

The present invention employs the following means to solve the above-mentioned 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 stored, the cover plate is formed with a pouring hole that penetrates the cover plate in the vertical direction and communicates with the inside of the container body and through which the contents are poured out, the pouring hole has a first hole portion and a second hole portion that are arranged in a state of being connected to each other in one direction when viewed from the vertical direction, the first hole portion is an elongated hole extending in the one direction, the second hole portion is an elongated hole extending in another direction perpendicular to the one direction when viewed from the vertical direction and protrudes outward from the first hole portion in the other direction, at least a portion of the lower surface of the cover plate that is connected to the opening periphery of the second hole portion extends downward as it approaches the second hole portion, a pair of opposing protrusions are provided on the upper surface of the cover plate that protrude upward and sandwich the first hole portion in the other direction, and the second hole portion is spaced apart in the one direction from an opposing portion of the opposing protrusions that faces the other opposing protrusion in the other direction, and protruding in the other direction, at least an end of the second hole portion opposite the first hole portion in the one direction is located at the same vertical position or higher than an end of the first hole portion opposite the second hole portion in the one direction , the covering plate penetrates in the vertical direction to communicate with the inside of the container body and is connected to the second hole portion, an air replacement hole is formed protruding from the end of the second hole portion opposite the first hole portion in the one direction to the opposite side of the first hole portion in the one direction, the size of the air replacement hole in the other direction is smaller than the size of the second hole portion in the other direction, when the contents are poured out from the pouring hole, outside air is introduced into the container body through the air replacement hole, and at least an end of the air replacement hole opposite the second hole portion in the one direction is located higher than an end of the first hole portion of the pouring hole opposite the second hole portion in the one direction .

According to the present invention, a pair of opposed protrusions that protrude upward and sandwich the first hole in the other direction are provided on the upper surface of the covering plate, so that the contents poured out from the first hole are sandwiched between the pair of opposed protrusions. Therefore, when the container body is tilted slightly to pour the contents out from the first hole, the width of the contents flowing down can be kept narrow.
Since the end of the second hole portion opposite the first hole portion along at least the one direction is located at the same position in the vertical direction as the first hole portion or above it, when the container body is tilted slightly, it is possible to prevent the contents within the container body from entering the second hole portion, and the width of the contents flowing down from the pouring hole can be reliably maintained narrow.
Since the second hole portion is separated in the one direction from the opposing portion of the opposing protrusions and protrudes in the other direction, when the container body is tilted significantly and the contents are poured out not only from the first hole portion but also from the second hole portion, the contents climb up onto the pair of opposing protrusions and overcome them in the one direction, thereby widening the width of the contents flowing down from the pouring hole.
As described above, when pouring the contents from the pouring hole, the width of the contents flowing down can be made different depending on whether the container body is tilted slightly or greatly.
At least the portion of the underside of the covering plate that is connected to the opening peripheral portion of the second hole portion extends downward toward the second hole portion, so that when the container body is tilted slightly, the contents inside the container body can be reliably prevented from entering the second hole portion.

Since the air replacement hole is formed in the cover plate, when the container body is tilted, the contents can be poured out from the pouring hole while outside air is being introduced into the container body through the air replacement hole.
Since the end of the air replacement hole opposite the second hole portion along at least the one direction is located above the pouring hole, when the container body is tilted, the contents inside the container body can be prevented from entering the air replacement hole.

A protrusion protruding downward may be formed at least at the connection portion between the second hole portion and the first hole portion on the periphery of the opening of the pouring hole on the underside of the covering plate.

In this case, a downwardly protruding ridge is formed on the opening periphery of the pouring hole on the underside of the covering plate, at least at the connection part of the second hole with the first hole. When the container body is tilted slightly, the contents inside the container body collide with the ridge, preventing them from entering the second hole, and the width of the contents flowing down from the pouring hole can be reliably maintained narrow.

According to this invention, when pouring the contents from the pouring hole, the width of the contents that flow down can be made different when the container body is tilted slightly from when it is tilted significantly.

FIG. 2 is a vertical cross-sectional view of one embodiment of a spout cap. FIG. 2 is a top view of the pouring cap of FIG. 1 with the lid body open. FIG. 4 is a bottom view showing the state in which the lid is open and the pouring hole is exposed. FIG. 4 is a perspective view of FIG. 3 as seen obliquely from below.

Hereinafter, one embodiment of a dispensing cap will be described with reference to the drawings.
As shown in Figure 1, the dispensing cap 1 of this embodiment comprises an attachment tube 13 attached to the mouth portion W1 of the container body W in which the contents are contained, and a cap body 15 having a dispensing hole 14 that communicates with the inside of the container body W.
The container body W is formed into a cylindrical shape with a bottom, and the cap body 15 is formed into a cylindrical shape with a top. The container body W and the cap body 15 are arranged coaxially with a common axis O. Hereinafter, the direction along the common axis O will be referred to as the up-down direction, the direction intersecting the common axis O when viewed from the up-down direction will be referred to as the radial direction, and the direction going around the common axis O will be referred to as the circumferential direction.

A lid 27 is connected to the cap body 15 via a hinge portion 26. The lid 27 opens and closes the pouring hole 14 by rotating the lid 27 vertically around the hinge portion 26. It is also possible to use a lid that is detachably screwed onto the cap body 15 without providing the hinge portion 26.
The cap body 15 includes a covering tube 28 that covers the mounting tube 13 from the outside in the radial direction. The lower ends of the mounting tube 13 and the covering tube 28 are connected to each other. The covering tube 28 and the mounting tube 13 are integrally formed.
Here, the lower ends of the mounting tube 13 and the covering tube 28 are connected to each other by a breakable connecting piece 29a and an unbreakable connecting portion 29b. The connecting piece 29a and the connecting portion 29b are provided at different circumferential positions. The connecting portion 29b connects the portions of the lower ends of the mounting tube 13 and the covering tube 28 that are located on opposite sides of the hinge portion 26 that radially sandwich the common axis O. A plurality of connecting pieces 29a are provided at intervals in the circumferential direction.
With the lid body 27 in an open state, the lid body 27 is pulled up together with the covering tube 28 via the hinge portion 26, and the mounting tube 13 is pulled up toward the mouth portion W2 via the connecting portion 29b while breaking the multiple connecting pieces 29a, thereby separating the cap body 15 from the container body W.

The top wall portion 22 of the cap body 15 has a ring plate portion 23, a sealing tube portion 24, and a covering plate 25.

The ring plate portion 23 extends radially inward from the upper end portion of the mounting tube 13. The ring plate portion 23 is disposed on the upper opening edge of the mouth portion W1.
The cylindrical seal portion 24 extends downward from the inner peripheral edge of the annular plate portion 23. The cylindrical seal portion 24 is tightly fitted into the mouth portion W1.
The covering plate 25 is provided within the lower end of the sealing tube portion 24 and closes the inside of the mouth portion W1. The covering plate 25 is formed with a pouring hole 14 penetrating in the vertical direction. A pouring tube 25d is formed on the upper surface of the covering plate 25, surrounding the pouring hole 14 from the outside in the radial direction and extending upward. A closing plate 25b is connected to the inner peripheral surface of the pouring hole 14 via a breakable thin portion 25a. A pull ring 25c protruding upward is formed on the closing plate 25b.

In this embodiment, as shown in Figs. 2 to 4, the pouring hole 14 includes a first hole portion 11 and a second hole portion 12 which are aligned in one direction when viewed from the up-down direction.
The one direction coincides with a radial direction in which a straight line passing through the common axis O and the hinge portion 26 extends.
Hereinafter, in the one direction, the side on which the hinge portion 26 is located with respect to the common axis O will be referred to as the rear, and the opposite side will be referred to as the front.

The first hole 11 is a long hole extending rearward from a front end of an inner portion 25e of the covering plate 25, the inner portion 25e being located radially inward from the pouring tube 25d. The rear end of the first hole 11 is located forward of the radial center of the covering plate 25.
Of the lower surface of the cover plate 25 , at least a portion that is continuous with the opening periphery of the second hole portion 12 extends downward toward the second hole portion 12 .
In the illustrated example, the entire inner portion 25 e of the cover plate 25 , including the portion continuing to the opening periphery of the first hole portion 11 , extends downward toward the pouring hole 14 .

A pair of opposing protrusions 16 are provided on the upper surface of the covering plate 25 at a portion adjacent to the periphery of the opening of the first hole 11, protruding upward and sandwiching the first hole 11 in another direction perpendicular to the one direction when viewed from the top-bottom direction.

The opposing protrusion 16 extends upward from the rear to the front. The opposing protrusion 16 has an opposing portion 16a that faces the other opposing protrusion 16 in the other direction, which approaches each other from the rear to the front. The upper end of the opposing portion 16a of the opposing protrusion 16 is formed in a curved shape protruding toward the other opposing protrusion 16. The opposing protrusion 16 is connected to the inner surface of the dispensing tube 25d. The front end of the opposing portion 16a is located forward of the front end of the first hole 11. The rear end of the opposing protrusion 16 extends forward from the inner surface of the dispensing tube 25d toward the first hole 11 along the other direction. The rear end of the opposing protrusion 16 is connected to the upper surface of the covering plate 25 without any steps.

The second hole portion 12 is separated from the opposing portion 16a of the opposing protrusion 16 in the one direction and protrudes outward in the other direction. The second hole portion 12 is a long hole extending in the other direction. The second hole portion 12 is located rearward of the opposing portion 16a. The size of the second hole portion 12 in the one direction decreases as it moves away from the first hole portion 11 side in the other direction. In the illustrated example, the second hole portion 12 is separated from the inner peripheral surface of the pouring tube 25d toward the inside in the other direction. That is, the outer end portion of the second hole portion 12 in the other direction is located inside the outer end portion of the rear end portion of the opposing protrusion 16 in the other direction. The outer end portion of the second hole portion 12 in the other direction is located rearward of the rear end portion of the opposing protrusion 16. The outer end portion of the second hole portion 12 in the other direction is located in the center of the second hole portion 12 in the one direction.
When viewed from the top and bottom, the pouring hole 14 has a symmetrical shape with respect to a straight line that passes through the common axis O and extends in the one direction.

At least the rear end portion of the second hole portion 12 (the end portion opposite the first hole portion 11 along the one direction) is located at the same position as the first hole portion 11 in the up-down direction or above it.
The front portion of the opening periphery of the first hole 11 extends downward toward the rear, and the rear portion extends straight in the one direction. The front end of the first hole 11 is located at the uppermost position.
The second hole 12 extends upward toward the rear. The rear end of the second hole 12 is located at the same position as or above the front end of the first hole 11 in the up-down direction.

As shown in Figures 3 and 4, a downwardly protruding ridge 18 is formed on the opening periphery of the pouring hole 14 on the underside of the covering plate 25, at least at the connection portion between the first hole 11 and the second hole 12. The ridge 18 extends along the inner circumferential surface of the pouring hole 14 when viewed from the top-bottom direction. The ridge 18 is provided across the rear end of the first hole 11 and the center of the second hole 12 in the one direction. At least a portion of the ridge 18 extends in the other direction.

An air replacement hole 17 is formed in the covering plate 25, protruding rearward (opposite the first hole portion 11 along the one direction) from the rear end portion of the second hole portion 12 (the end portion opposite the first hole portion 11 along the one direction).
The size of the air replacement hole 17 in the one direction is smaller than the size of the second hole portion 12 in the one direction. The size of the air replacement hole 17 in the other direction is smaller than the size of the second hole portion 12 in the other direction. The air replacement hole 17 protrudes rearward from the center of the second hole portion 12 in the other direction.
As shown in FIG. 1 , at least the rear end portion (the end portion opposite the second hole portion 12 along the one direction) of the air replacement hole 17 is located above the pouring hole 14 .

The blocking plate 25b is integrally connected to the inner circumferential surfaces of the pouring hole 14 and the air replacement hole 17 via the thin-walled portion 25a. A pull ring 25c is connected to the upper surface of the rear end of the blocking plate 25b that blocks the air replacement hole 17.

Next, we will explain the function of the dispensing cap 1.

First, the lid body 27 is rotated upward around the hinge portion 26 to open the top wall portion 22 of the cap body 15, and then the pull ring 25c is pulled up to break the thin portion 25a, the closure plate 25b is removed, and the pouring hole 14 and the air replacement hole 17 are opened.
Next, when the container body W is tilted slightly to pour the contents out through the pouring hole 14, the contents are poured out through the first hole portion 11 of the pouring hole 14 and flow down between the opposing portions 16a of the pair of opposing protrusions 16.
In addition, when the container body W is tilted significantly to pour the contents through the pouring hole 14, the contents are poured out not only from the first hole portion 11 but also from the second hole portion 12, climbing up onto a pair of opposing protrusions 16 and flowing down while climbing over the opposing protrusions 16 forward.

As described above, according to the pouring cap 1 of this embodiment, a pair of opposed protrusions 16 that protrude upward and sandwich the first hole 11 in the other direction are provided on the upper surface of the covering plate 25, so that the contents poured out from the first hole 11 are sandwiched between the pair of opposed protrusions 16. Therefore, when the container body W is tilted slightly to pour the contents out from the first hole 11, the width of the contents flowing down can be kept narrow.
At least the rear end of the second hole portion 12 is located at the same vertical position as or above the first hole portion 11, so that when the container body W is tilted slightly, it is possible to prevent the contents within the container body W from entering the second hole portion 12, and the width of the contents flowing down from the pouring hole 14 can be reliably maintained narrow.

The second hole 12 is spaced apart in the one direction from the opposing portion 16a of the opposing protrusion 16 and protrudes in the other direction, so that when the container body W is tilted significantly and the contents are poured out not only from the first hole 11 but also from the second hole 12, the contents climb up and overcome the pair of opposing protrusions 16 in the one direction, widening the width of the contents flowing down from the pouring hole 14.

As a result, when pouring the contents from the pouring hole 14, the width of the contents that flow down can be made different when the container body W is tilted slightly compared to when the container body W is tilted significantly.

At least the portion of the underside of the covering plate 25 that is connected to the periphery of the opening of the second hole 12 extends downward toward the second hole 12, so that when the container body W is tilted slightly, the contents inside the container body W can be reliably prevented from entering the second hole 12.

Since an air replacement hole 17 is formed in the covering plate 25, when the container body W is tilted, the contents can be poured out from the pouring hole 14 while outside air is introduced into the container body W through the air replacement hole 17.
At least the rear end of the air replacement hole 17 is located above the pouring hole 14, so that when the container body W is tilted, the contents inside the container body W can be prevented from entering the air replacement hole 17.

A downwardly protruding ridge 18 is formed on the opening periphery of the pouring hole 14 on the underside of the covering plate 25, at least at the connection part with the first hole 11 in the second hole 12. When the container body W is tilted slightly, the contents in the container body W collide with the ridge 18, preventing them from entering the second hole 12. This ensures that the width of the contents flowing down from the pouring hole 14 remains narrow.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

The air replacement holes 17 and the protrusions 18 do not have to be formed in the cover plate 25 .
The protrusion 18 may be provided, for example, at least at the front end of the second hole portion 12 in the opening peripheral portion of the pouring hole 14 on the lower surface of the cover plate 25 .
The rear end of the opposing protrusion 16 may be connected to the upper surface of the covering plate 25 via a step.
The facing portion 16a may extend straight in the one direction.
The rear end of the opposing protrusion 16 may extend straight in the other direction.
The pull ring 25c and the closure plate 25b do not need to be provided.

In addition, the components in the above embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above embodiments and variations may be combined as appropriate.
