Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring mechanism and a pouring cap provided at an opening of a container filled with a liquid agent such as a liquid detergent, a softening agent or a bleaching agent.

[0002]

Some containers such as liquid detergents are provided with a weighing function in order to easily obtain an accurate amount. In particular, a typical method is to once pour out a liquid agent from a container into a lid having a scale on it, and a desired amount is set aside and put into the washing machine tub.

Here, FIG. 7 shows a state during measurement of a liquid agent.
Further, FIG. 8 and FIG. 9 respectively show a cross-sectional view and a plan view of a main part of the container, that is, a liquid agent dispensing cap (dispensing cap) provided at the opening of the container. 7 to 9, D is a measuring lid, E is a pouring cap, and F is a container body. The spout cap E is always screwed into the opening of the container body F. On the other hand, the measuring lid D is screwed onto the spout cap E at the time of storage, but is detached from the spout cap E at the time of use and, as shown in FIG.
The liquid inside is set aside.

Reference numeral 21 denotes a base portion of the pouring cap E, and a screw portion 22 screwed to an opening portion of the container body F on an inner peripheral surface thereof.
However, the outer peripheral surface is provided with a screw portion 23 that is screwed into the measuring lid D. Reference numeral 24 is a guide portion, which is provided upright from the tapered bottom surface 25 of the base portion 21. This guiding part 24
As can be seen from FIG. 9, has a substantially C-shaped cross section, and a notch 26 along the axial direction is formed in the upper side portion when the liquid agent is dispensed.

Reference numeral 27 denotes a large opening (a guide portion port) connected to the internal space of the container body F, and when the container body F is tilted, the liquid agent is discharged from the guide portion 24 through the large opening 27. Two
Reference numeral 8 is a small opening continuing from the large opening 27 and is formed at the lowest part of the bottom surface 25. After use, the residual liquid that has flowed down on the bottom surface 25 along the inner wall surface of the measuring lid D attached to the pouring cap E returns to the inside of the container body F again through the small opening 28.

By the way, the pouring cap E having such a structure
In the container provided with, when the container body F is tilted, the liquid agent suddenly discharges and overflows from the measuring lid D in many cases, which causes difficulty in measuring. In particular, since a liquid agent having a high fluidity such as a bleaching agent is ejected very rapidly, it is necessary to operate it with great care, which takes a lot of time and effort.

Further, the liquid agent is directly fed from the tip of the guiding portion 24.
It is often used to pour and apply to clothes, but in the case of sudden ejection, the liquid agent is often wasted. The present invention has been made to solve these problems, and an object thereof is to provide a dispensing mechanism capable of easily dispensing an appropriate amount of liquid agent and reducing waste of the liquid agent.

[0008]

The above-mentioned object of the present invention is a pouring mechanism provided in an opening of a container, wherein a guiding part provided in the opening of the container and a guiding part mouth of the guiding part are provided. The present invention is achieved by a pouring mechanism characterized in that it has a closing surface portion that closes most of the remaining portion and an air vent portion.

Further, the cap is a pouring cap provided at the opening of the container, and the pouring cap is provided with a guiding part, and most of the guiding part of the guiding part is left behind. This is achieved by a pouring cap, which is characterized in that a closing surface portion for closing the above is provided, and further an air vent portion is provided.

Also, a pouring cap provided in the opening of the container, the base engaging with the opening of the container,
A guide portion that is erected from the bottom surface of the base portion and has a portion of the peripheral wall cut out along the axial direction, a closing surface portion provided corresponding to an inner region of the peripheral wall of the guide portion, and the closing surface portion. And a discharge hole formed at a position facing the notch with the center of the guiding portion interposed therebetween, and a discharge cap.

That is, according to the present invention, the closing surface portion is provided in the inner area of the peripheral wall of the guiding portion, and the liquid agent is discharged only from the hole smaller than the diameter of the guiding portion formed in the closing surface portion. Stable supply is possible without discharging a large amount. In other words, if the diameter of the guide portion is simply made smaller and the discharge hole is made smaller accordingly, when the liquid agent is discharged from the air vent portion provided in the closed surface portion,
Most of the liquid does not get caught in the guiding part and wraps around the outside.
And in such a situation, the liquid agent cannot be dispensed well,
There is a lot of waste. For this reason, the diameter of the guiding portion must be increased to some extent. However, if the ejection hole is enlarged in accordance with the large diameter of the guiding portion, a large amount of liquid will be ejected when the container is largely tilted. However, in the case of the configuration according to the present invention, there is no drawback as described above, a large amount of liquid agent is not discharged, and stable supply is possible. Therefore,
Even a liquid having a large fluidity can be easily handled, and an appropriate amount can be dispensed without waste.

Particularly, when the holes (holes for venting air and / or residual liquid, which are also referred to as second holes hereinafter) are provided in the vicinity of the notch position of the guiding portion, air replacement is smooth. The liquid will be dispensed without pulsation. If the air vent hole is provided close to the discharge hole of the guide part, the air vent function is essentially to discharge the liquid agent as well as the discharge hole, and pulsation when pouring the liquid agent is avoided. I can't. However, by providing the air vent hole to some extent away from the discharge hole, such a defect is eliminated.

It is preferable that an annular wall that engages with the lid of the container, particularly an annular wall that is erected so that the peripheral wall of the measuring portion on the lid side is located inside, is preferably provided around the guide portion of the above invention. As a result, the residual liquid is smoothly collected and does not leak. Moreover, it is convenient because the lid of the container can be engaged. In addition, the bottom surface of the base is formed in a tapered shape in which the notch side of the peripheral wall of the guide portion is low, and the base bottom surface near the notched position of the peripheral wall of the guide portion has a hole (second
Is preferably formed. As a result, the air can be replaced well, the liquid agent can be poured out without pulsation, and the residual liquid can be smoothly recovered without leakage.

Further, a hole (second hole) connected to the inside of the container is formed on the bottom surface of the base near the cutout portion of the guide wall and outside the virtual line corresponding to the cutout of the guide portion. It is preferable that the width of the notch on the base end side of the guide portion is larger than the width of the hole (second hole). That is, a hole for air bleeding and / or residual liquid recovery is formed on the bottom surface of the base in the vicinity of the cutout position of the peripheral wall of the guide part, and outside the virtual line corresponding to the cutout of the guide part,
When the width of the notch on the proximal end side of the guiding portion is made larger than the width of the hole (second hole), the liquid agent is discharged from the second hole in a state where the container is tilted to the left and right. Also, the liquid that runs down passes through the notch. Therefore, the liquid agent will not be ejected outside the guide part and will be collected in the guide part.
Staining is unlikely to occur.

Further, it is preferable that a long hole is formed on the bottom surface of the base portion so as to connect to the inside of the container across a virtual line corresponding to the notch of the guiding portion. That is, even if the liquid agent is discharged from the long hole for venting air at the time of pouring, there is a margin in the upper portion of the long hole for exhibiting a sufficient air replacement function. Therefore, air replacement is reliably performed, and the liquid agent can be dispensed without pulsation.

Further, it is preferable that the guide portion has a substantially V-shaped cross section, and a discharge hole is formed on the apex side thereof in contact with the inner surface of the peripheral wall of the guide portion. As a result, the liquid agent can be accurately poured and applied to a desired point without being dispersed in a wide range, and the waste of the liquid agent can be further reduced. Further, it is preferable that the guide portion has a substantially C-shaped cross section in which a part thereof protrudes outward, and a discharge hole is formed on the protruded side in contact with the inner surface of the peripheral wall of the guide portion. Even with this, like the one with a substantially V-shaped cross section, the liquid agent can be accurately dispensed to a desired point without dispersing it in a wide range.
It can be applied.

1 to 4 show a first embodiment of a pouring mechanism (pouring cap) according to the present invention.
3 is a cross-sectional view of the pouring cap attached to the container body and the measuring lid attached, FIG. 2 is a cross-sectional view of the pouring cap, and FIG.
Is a plan view of the pouring cap, and FIG. 4 is a cross-sectional view showing a usage state.

In each drawing, A is a measuring lid, B is a pouring cap,
C is the container body. The spout cap B is always screwed into the opening of the container body C as shown in FIG. Although the pouring cap B is configured separately from the container body C, it may be integrated. The measuring lid A is screwed onto the spout cap B during storage, but is detached from the spout cap B at the time of use to separate the liquid agent in the container body C as shown in FIG.

Reference numeral 1 denotes a base portion of the pouring cap B, and a screw portion 2 which is screwed into the opening portion of the container body C is formed on the inner peripheral surface thereof.
Further, a screw portion 3a screwed with the measuring lid A is provided on the outer peripheral surface of the annular wall 3 provided around the guide portion 4 which will be described later.
Reference numeral 4 denotes a guiding portion, which is a tapered bottom surface 5 of the base portion 1.
To stand from. As shown in FIG. 3, the guiding portion 4 has
It has a substantially V-shaped cross-section with gently curved vertices,
Notches 6 are provided along the axial direction so as to have equal intervals or large intervals on the distal end side and the proximal end side.
In addition, the cross-sectional shape of the guide portion 4 may be, for example, a C-shape or a U-shape.

Reference numeral 7 is a closed surface portion provided corresponding to the inner area of the peripheral wall of the guiding portion 4, and is formed integrally with the base portion 1 in this embodiment. A separate plate may be attached. Reference numeral 8 denotes a discharge hole, which is provided in the closed surface portion 7 at a position facing the notch 6 with the center of the guide portion 4 interposed therebetween and in contact with the inner peripheral surface of the guide portion 4. Reference numeral 9 is a second hole formed in the lowest part of the bottom surface 5, which is used for air replacement when the liquid agent is dispensed, and after the use, it is transmitted through the inner wall surface of the reloaded measuring lid A. The residual liquid that flows down on the bottom surface 5,
Again, it plays a role of returning to the inside of the container body C. The width of the second hole 9 is smaller than the width of the notch 6, and even if the liquid agent is discharged from the second hole 9 in a state where the container is tilted to the left and right, the liquid agent that flows down passes through the notch 6. Therefore, the liquid agent does not jump out of the guiding portion 4 and is collected in the guiding portion 4, so that stains are unlikely to occur.

When the container having the pouring cap constructed as described above is tilted during pouring, the guiding portion 4
The liquid agent is discharged from the discharge hole 8 whose area ratio is smaller than that of
And is supplied at a desired amount from its tip. Therefore, even if the container is largely tilted, the liquid agent does not suddenly discharge and does not overflow from the measuring lid A in an instant. In particular, even a highly fluid liquid agent such as a bleaching agent can be stably supplied and can be easily handled,
The time and effort required for weighing is greatly reduced.

In particular, since the second hole 9 is provided, air is introduced / replaced in the container body C in exchange for the discharged liquid agent, so that pulsation does not occur at the time of discharging and the liquid agent does not scatter. . Further, even when the liquid agent is directly poured from the tip of the guiding portion 4 to the clothes and applied, the liquid agent does not suddenly discharge and can be easily supplied in appropriate amounts, so that the waste of the liquid agent is reduced. it can.

Further, since the annular wall 3 is erected so that the peripheral wall of the measuring portion of the measuring lid A is located inside, when the measuring lid A is put on after use, the residual liquid adhering to the measuring portion of the measuring lid A is removed. It is collected in the container body C through the second hole 9 of the pouring cap B, the residual liquid is surely collected, and it does not leak. And,
It is convenient because the measuring lid A can be attached.
In addition, the base bottom surface 5 is formed in a tapered shape in which the notch 6 side of the guiding portion 4 peripheral wall is low, and the base bottom surface 5 near the notch 6 position of the guiding portion 4 peripheral wall has a second hole connected to the inside of the container body C. Since 9 is formed, not only the air is satisfactorily replaced and the liquid agent is discharged without pulsation, but when the measuring lid A is put over after use, the residual liquid adhering to the inside of the measuring portion of the measuring lid A is It is collected in the container body C through the second hole 9 of the pouring cap B, the residual liquid is surely collected, and it does not leak.

A second hole 9 is formed on the bottom surface 5 of the peripheral wall of the guiding portion 4 in the vicinity of the cutout 6 and outside the virtual line corresponding to the cutout 6 of the guiding portion 4. Since the width of the notch 6 on the base end side of the portion 4 is made larger than the width of the second hole 9, when the liquid agent is discharged with the container body C tilted to the left and right, the liquid agent is discharged from the second hole 9 Even if the liquid is discharged, the liquid agent that flows down passes through the notch 6 and is guided into the guide portion 4, so that stains are unlikely to occur.

Further, since the guide portion 4 has a substantially V-shaped cross section and the discharge hole 8 is formed at the apex side thereof, the discharged liquid is difficult to spread and can be concentrated and supplied at one point. It can be poured and applied at a desired point, and the waste of the liquid agent can be further reduced. 5 and 6 show a second embodiment of the pouring mechanism (pouring cap) according to the present invention. FIG. 5 is a sectional view of the pouring cap, and FIG. 6 is a plan view of the pouring cap.

Since the basic technical idea of the second embodiment is the same as that of the first embodiment, the structural parts having the same functions are designated by the same reference numerals as those in the first embodiment and will be described. Is omitted. In FIGS. 5 and 6, reference numeral 10 denotes a guide portion, which is provided upright from the tapered bottom surface 5 of the base portion 1.

As shown in FIG. 6, the guiding portion 10 has
A portion having a substantially C-shaped cross section protruding outward is provided with notches 11 along the axial direction thereof so as to have equal intervals or a large distance between the distal end side and the proximal end side.
Thus, by making the cross section of the guiding portion 10 substantially C-shaped with a part protruding outward, the liquid to be discharged is less likely to spread and can be concentrated and supplied at one point, that is, at a desired point. Can be dispensed and applied, reducing waste of liquid chemicals.

Reference numeral 12 denotes a discharge hole, which is provided at a position facing the notch 11 with the center of the guiding portion 10 sandwiched in the closed surface portion 7 and in contact with the inner peripheral surface of the guiding portion 10. The area of the discharge hole 12 is made somewhat larger than that of the first embodiment. 13 is notch 1
It is a long hole formed on the bottom surface 5 (closed surface portion 7) across the virtual line corresponding to 1. The long hole 13 is used for air replacement when the liquid agent is poured out, and after use, the residual liquid that flows down on the bottom surface 5 along the inner wall surface of the re-installed measuring lid is again put into the container body. Play the role of returning.

At the time of pouring the liquid agent, when the container having the pouring cap constructed as described above is tilted,
A discharge hole 12 having a smaller area ratio than the diameter of the guiding portion 10.
Although the liquid agent in the container is discharged from the container, it is not discharged in a large amount, but is guided to the guide portion 10 and is supplied in a desired amount from the tip thereof. Therefore, even if the container is largely tilted, the liquid agent does not suddenly discharge, and even a liquid agent with high fluidity can be stably supplied, can be easily handled, and the time and effort required for weighing can be greatly reduced. It will be reduced.

In particular, since the elongated slot 13 is provided for air replacement and residual liquid recovery, even if the liquid agent is discharged from this slot 13 by inclining the container greatly, the slot 1
There is a margin in the upper portion of 3 to be able to exert a sufficient air displacement function, and the elongated hole 13 is not completely blocked by the discharged liquid agent. Therefore, in exchange for the discharged liquid agent,
Since air is surely introduced / replaced in the container body, pulsation does not occur at the time of discharge and liquid agent does not scatter.
