Description

  The present invention relates to a pouring cap to be attached to a liquid container.

  Conventionally, an extraction cap for a liquid container has been provided with one hole for content liquid extraction, and an upper lid is attached to the hole to seal the hole.

Reality 07-41418

However, with the above cap, the content liquid often spills and adheres to the periphery of the spout as it is repeatedly used, and the perimeter of the spout is often contaminated over a wide range.
In view of the problems of the conventional cap as described above, an object of the present invention is to provide a dispensing cap that can reduce contamination of a liquid container due to dripping at the time of dispensing the content liquid.

  In a pouring cap composed of a cap main body 1 having an opening 3 for liquid pouring and an upper lid 2 detachably attached to the cap main body, the outer periphery of the opening 3 of the cap main body 1 is used as a base point and obliquely downward at a predetermined angle A side wall 4 that expands toward the diameter is provided, a side wall hole 5 that is formed in the side wall so that the content liquid is less likely to pass through than the opening, and a predetermined height is provided on the side wall 4 at a predetermined distance from the outer periphery of the opening. In addition, the inner wall of the upper lid 2 is provided with a storage wall 6, which is in contact with or close to the upper surface in the range from the outer periphery of the opening 3 of the side wall 4 to the lower end of the inner wall of the storage wall 6 when the cap body 1 is mounted. 4 A pressing part 7 for pressing the content liquid remaining on the upper surface is provided.

  Here, the opening means a hole having an area that does not hinder the content liquid dispensing, and its shape and the presence or absence of the outer frame are not limited. For example, the opening has an outer frame as shown in FIG. The upper end of the side wall 4 may be an opening as it is.

  The detachable upper lid means an upper lid that can be switched between the state in which the inner wall of the upper lid seals the opening and the state in which the inner wall of the upper lid is separated from the opening and the liquid can be poured out without any trouble. However, it is not always necessary that the cap body and the upper lid be completely separated. For example, as shown in FIG. 13, the cap body 8 and the upper lid 9 may be connected via the hinge portion 15.

  The side wall hole formed in a shape in which the content liquid is harder to pass than the opening portion means that the content liquid leaks from other than the opening portion 3 due to the surface tension acting on the content liquid flowing in the direction of the opening portion 3 in the side wall 4 at the time of pouring. It is a hole with a width narrowed to such an extent that it can be suppressed, or a hole with a similarly small area.

  The storage wall is a wall having a height and a width that can dam the content liquid dripping from the opening 3 at a predetermined position on the upper surface of the side wall 4.

  When the upper lid 2 attached to the cap body 1 is removed, the container body 19 is tilted and the content liquid is poured out, and then the container body is returned to the vertical state, the content liquid dripping from the opening 3 is removed from the outer periphery of the opening 3. Although attached to the area up to the inside of the storage wall 6, when the upper lid 2 is attached, the pressing portion 7 provided on the inner side of the upper lid comes into contact with or is close to the upper surface of the side wall 4. The content liquid that has been deposited is pushed back from the side wall hole 5 to the inside of the side wall 4 so that the amount of the content liquid adhering to the side wall 4 is greatly reduced.

It is a perspective view at the time of mounting this invention on the inclined surface of a container main body.

  Hereinafter, modes for carrying out the present invention will be described.

  A side wall 4 is provided that expands in a diagonally downward direction at a predetermined angle with the outer periphery of the opening portion 3 for dispensing the content liquid provided in the cap body 1 as a base point.

  The purpose of making the side wall 4 in the above-described shape is to encourage the content liquid dripping from the opening 3 to flow toward the storage wall 6 described later by gravity when the container body is returned to the vertical state after the content liquid is poured out. Moreover, it is for preventing the leakage to the exterior of the side wall 4 from the side wall hole 5 mentioned later by weakening the resistance concerning a side wall inner wall with a content liquid at the time of pouring.

The inclination angle of the side wall is not limited to one, and can be changed according to the viscosity of the content liquid so that leakage from the side wall hole 5 is suppressed.
For example, in the case of a high-viscosity content liquid, it may be possible to suppress the leakage by weakening the resistance applied to the inner wall of the side wall by enlarging the inclination angle and promoting the flow of the content liquid to the opening 3 at the time of pouring. It is done.

  Moreover, the degree of diameter expansion of the side wall can be changed within a range that satisfies the above-mentioned purpose. For example, as shown in FIG. 4, the degree of diameter expansion may be increased toward the lower part.

Side wall holes 5 are formed in the side wall 4 so as to make it difficult for the content liquid to pass through the opening 3.
The purpose of providing the side wall hole is to pass the content liquid on the side wall 4 dripping from the opening 3 at the time of pouring into the side wall 4 by pressing the pressing part 7 provided on the inner wall of the upper lid, which will be described later, by closing the upper lid 2. At the same time, it is necessary to satisfy the purpose of suppressing the leakage from the side wall hole 5 to the outside of the side wall and allowing it to flow out only from the opening 3 when the content liquid is poured out.

  As an example of the shape of the side wall hole that satisfies both of the above two purposes, a slit (slit) that narrows the gap to such an extent that leakage from the side wall hole is suppressed by surface tension acting on the content liquid flowing in the side wall 4 during pouring. ), Or a circle or polygon with a similar area reduction. Any of these shapes may be used alone or in combination.

  Examples of the arrangement of the side wall holes include an example in which slits are provided radially from the opening 3 (FIG. 5), an example in which slits are provided spirally from the opening 3 (FIG. 6), and a circular, elliptical, An example (FIG. 7) in which a plurality of holes such as squares are provided at an appropriate distance from each other can be mentioned.

  The upper end position of the side wall hole 5 is arbitrary. For example, when the slit is provided, the slit may reach the upper surface of the opening as shown in FIG. 8, but the lower end position is in contact with the lower end of the inner wall of the storage wall 6 described later. It is desirable. (FIG. 5, FIG. 6) This is to prevent the content liquid from remaining in the lowermost inner wall of the storage wall 6 when pressed by the pressing unit 7 described later.

Further, in the case of a side wall hole having a circular shape or a polygonal shape, the lowermost hole is preferably in contact with the lower end of the inner wall of the storage wall 6 for the same reason. (Fig. 7)
A storage wall 6 having a predetermined height is provided on the side wall 4 at a predetermined distance from the outer periphery of the opening 3.
The purpose of the storage wall is to dam the content liquid dripping from the opening 3 at a predetermined position on the upper surface of the side wall 4 and is sandwiched between the upper lid pressing portion 7 and the upper surface of the side wall 4 when the upper lid 2 described later is mounted. It is also possible to close the gap on the outer edge side of the pressing part 7 and the side wall 4 so that the content liquid does not leak. (Fig. 12)
The distance from the outer periphery of the opening 3 to the storage wall 6 needs to be adjusted according to the viscosity of the content liquid. That is, the position where the lower end of the content liquid dripping from the opening when the container body is returned to the vertical state after pouring the content liquid is attached to which position on the side wall 4 depends on the viscosity of the content liquid. This is because the position of the storage wall needs to be outside the lower end of the content liquid adhering to the side wall. (FIGS. 10 and 11)
The height of the storage wall is not limited, but a height is required to store the drained content liquid until the upper lid is attached.

  Further, the storage wall does not necessarily need to be formed in a series of wall shapes surrounding the opening without any gap. For example, when the cap main body is attached to the inclined surface of the container main body as shown in FIG. 17, it is considered that the liquid content only spills below the opening 3 due to gravity. There may be an embodiment in which the storage wall is not provided in the part.

In the above case, the side wall area may be partially reduced by expanding the opening upward for the same reason as described above. (Fig. 17)
On the inner wall of the upper lid 2, there is provided a pressing portion 7 that comes into contact with or is close to the upper surface in the range from the outer periphery of the opening 3 of the side wall 4 to the lower end of the inner wall of the storage wall 6 when the cap body 1 is mounted.
The purpose of the pressing portion is to return the liquid inside the side wall 5 by passing through the side wall hole 5 by pressing the content liquid dripping from the opening 3 and adhering onto the side wall 4 against the side wall 4. (Fig. 12)
Therefore, it is desirable to form the pressing portion 7 in a shape that overlaps as much as possible on the upper surface of the side wall 4 in the range from the outer periphery of the opening 3 to the lower end of the inner wall of the storage wall 6 when the upper lid 2 is mounted.

  When the pouring cap body 8 and the upper lid 9 are connected via the hinge portion 10 as shown in FIG. 13, the upper surface of the side wall 11 is not accompanied by the horizontal rotation of the upper lid 9 when the upper lid 9 is attached or detached. In addition, since the inner surface of the pressing portion 14 that is superposed on the inner surface does not necessarily have to be smooth, it is possible to provide unevenness in a shape that allows the drained content liquid to flow into the side wall hole 12 on the upper surface of the side wall and the inner surface of the pressing portion. .

As an example, the side wall 11 is curved so that the slit-shaped side wall holes 12 provided radially from the opening 10 to the lower end of the inner wall of the storage wall 13 are valleys, and the middle line part between adjacent side wall holes is a mountain, and the upper lid is pressed together. It is conceivable to form irregularities on the inner surface of the portion 14 so as to overlap the irregularities on the side walls without gaps. (FIGS. 13 and 15)
The advantage of having the side wall and the upper lid pressing portion in the above-described shape is that the dripping content liquid is urged to flow toward the side wall hole of the concave portion of the side wall 11 by gravity before closing the upper lid 9, and the inside of the pressing portion 14 is closed when the upper lid is closed. Since the content liquid that has been spilled from the convex portion on the side surface is pushed down toward the side wall hole 12 directly below, the content liquid is pushed back into the side wall efficiently.
