DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder meter attached to an opening of a powder container, and to a powder meter capable of measuring a variable amount.

[0002]

2. Description of the Related Art Conventionally, as a powder container for accommodating a powder detergent, a plastic or paper box has generally been used, and a measuring spoon or a measuring cup has been used for the measurement.

On the other hand, in recent years, the development of so-called compact detergents in which the amount of detergent required for washing has been greatly reduced has progressed, and accordingly, the amount of powder detergent per package has decreased, and the size of containers has been reduced. When using a powder detergent, a simpler method is to use a powder detergent in a bottle-type with a powder meter attached to it, as opposed to a conventional method of measuring the container using a measuring spoon or measuring cup from a container. It is stored in a powder container, and a method of directly discharging a predetermined amount from a bottle-shaped powder container without using a measuring spoon or a measuring cup when using a powder detergent is adopted. .

Further, since the amount of detergent required for washing varies depending on the amount of washing and the like, it is desirable that a powder measuring device attached to a bottle-type powder container can vary the amount that can be measured. As such a powder meter of variable metering, for example, as in a powder meter tap 50 shown in FIG. 6, an upper lid 51 with a guide plate that moves vertically by a hinge mechanism is provided. It is known that the amount measured in the chamber 52 is increased or decreased so that the amount of squirting is changed stepwise (actually 4-54).
939). Further, as in the case of the measuring tap 60 shown in FIG. 7, there is also known a measuring tap in which the volume of the measuring chamber 62 is continuously changed by sliding the adjusting member 61 in the front-rear direction (Japanese Utility Model 5-28218). No.).

[0005]

However, in the powder measuring tap 50 shown in FIG. 6, since the upper lid 51 which is moved up and down in order to make the swinging amount variable is provided inside the powder measuring tap 50, adjustment is made. There is a problem in that the upper lid 51 is moved up and down by a hinge mechanism, so that the adjustment range of the swing amount cannot be increased.

Further, in the measuring tap 60 shown in FIG. 7, the knob 63 is pinched to adjust the swing-out amount.
1 is slid in the front-rear direction, but the operation of picking up the knob 63 and sliding the adjustment member 61 is a fine work of the hand, and considerable attention is required to slide the adjustment member 61 by a predetermined amount. There is a problem that is. There is also a problem that the adjustment width of the swing amount cannot be increased. Furthermore, in the measuring tap 60, since the volume of the measuring chamber 62 changes continuously, not stepwise, by the sliding of the adjusting member 61, there is a problem that it is rather difficult to dispense a predetermined amount of dispense with good reproducibility.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and in making the measuring volume of a powder measuring device attached to a powder container variable, the range of adjustment of the amount of ejection is increased. Can be set,
It is another object of the present invention to enable accurate adjustment to a predetermined swing amount by a simple adjustment operation.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a powder measuring device attached to an opening of a powder container, wherein the measuring device has a cup portion having a cylindrical side wall. It consists of a suspended partition plate and a cap attached to the upper end of the cup, the cup having a powder inlet on the side wall, the cap having a powder outlet, and a partition. The lower end of the plate is located below the powder inlet, and the inside of the cup is divided into a powder inlet side area and a powder outlet side area, and the cap and cup can slide up and down. And the cap portion and the partition plate portion are slid up and down with respect to the cup portion by sliding the cap portion up and down with respect to the cup portion.

According to the powder meter of the present invention, by sliding the cap portion and the cup portion up and down, the portion above the powder inlet of the cup side wall on the powder inlet side and the partition plate are separated. The volume of the temporary weighing unit surrounded by and the volume of the weighing unit below the partition plate is increased or decreased to make the weighing volume variable. The variable amount of the volume of the temporary weighing unit and the weighing unit by the vertical slide can be set to be larger than the variable amount of the conventional powder weighing device. Therefore, it is possible to set a large adjustment width of the swing amount, and it is possible to accurately adjust the swing amount to a predetermined swing amount.

Further, since the cap portion can be attached so as to cover the outer surface of the powder measuring device, the cap portion and the cup portion can be easily slid to a length corresponding to a predetermined swing amount. , It is possible to precisely adjust the metering volume to the desired amount. Further, when the mounting portion of the cap portion is configured so that the slide is performed stepwise, it is possible to measure a predetermined amount stepwise with good reproducibility.

In addition, when the powder weighing device of the present invention is attached to a powder container, the volume of the powder weighing device occupying the powder container is constant irrespective of the magnitude of the amount of squirting. Therefore, when filling a powder container with powder,
Irrespective of the amount adjusted by the powder meter, the powder can always be completely filled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. In each of the drawings, the same reference numerals represent the same or equivalent components.

FIG. 1 is a sectional view of a powder measuring device according to one embodiment of the present invention attached to an opening of a powder container, FIG. 2 is an exploded perspective view of the powder measuring device, and FIG. Explanatory drawing of a mode in which a cap portion and a cup portion of a weighing machine are slid, FIG.
FIG. 4 is an explanatory view of a swing-out mechanism of the powder weighing machine.

As shown in FIG. 1, this powder measuring device 10
Is used by being attached to the opening 2 of the bottle-shaped powder container 1. As shown in FIGS. 1 and 2, the powder weighing device 10 includes a cup 20 having a cylindrical side wall, a partition plate 30 suspended in the cup 20, and an upper end of the cup 20. And a cap part 40 attached so as to cover.

The cup portion 20 has a powder inlet 22 in about a half circumferential surface of the side wall 21. The cup 20
Has an upright wall 23 on the upper edge thereof, which serves as a mounting portion for the cap portion 40, and a screw portion 24 with the opening wall 3 of the powder container 1 below the upright wall 23. It is inserted into the opening 2 of the body container 1.

The cap section 40 has a powder outlet 41, and an upper lid 42, which is opened and closed by a hinge mechanism, is fitted to the powder outlet 41 as a lid.

The partition plate portion 30 is formed of a single plate-shaped member hanging down in the cup portion 20, and its lower end 30 a is located below the powder inlet 22. And cup part 2
0, a cup portion side wall 21 on the powder inflow port 22 side, a region 21a located above the powder inflow port 22, a temporary weighing portion A surrounded by a partition plate portion 30, and a partition plate. It divides into a measuring section B below the lower end 30a of the section 30 and a discharge channel C that connects the measuring section B and the powder discharge port 41.
In this case, in order to improve the measuring accuracy, it is preferable that the volume of the temporary measuring section A is set slightly larger than the predetermined amount of powder to be measured, and is larger than the volume of the measuring section B.

The partition plate portion 30 is formed integrally with the cap portion 40. The cap portion 40 and the cup portion 20 are erected so that the cup portion 20 can be slid up and down stepwise at their mounting portions. The inner surface of the wall 23;
A plurality of horizontal ribs 25 and 43 are formed on both side walls of the cap portion 40 in contact with it.

When the position of the cap portion 40 with respect to the cup portion 20 is changed by sliding in this mounting portion,
The position of the partition plate 30 relative to the cup 20 also changes. Therefore, as shown in FIG. 3A, the cap portion 40 is fitted to the cup portion 20 most deeply, and the volume of the temporary weighing portion A is reduced. And the lower end 30a of the partition plate portion 30 is deeper than the powder inlet 22 of the cup portion 20, and the volume of the cup portion 20 defined below the lower end 30a of the partition plate portion 30 is measured. The volume of part B is
3C, the cap portion 40 is fitted to the cup portion 20 most shallowly, and the lower end 30a of the partition plate portion 30 is substantially in contact with the powder inlet 22 as shown in FIG. FIG. 3 shows a state in which the volumes of the temporary weighing unit A and the weighing unit B have reached the maximum value in the powder weighing device 10.
As shown in (b), a state intermediate between these two states can be taken. In addition, these respective states are fixed by the above-described horizontal ribs 25 and 43 in the powder squirting operation described below, and stable weighing becomes possible. In any state, the lower end 30a of the partition plate 30 is connected to the powder inlet 2 in order to form the temporary weighing section A.
2 below.

The operation when the powder contained in the powder container 1 to which the powder measuring device 10 is attached is shaken out is as follows.

First, as shown in FIG. 4A, the powder container 1 is turned upside down. As a result, the powder S flows into the temporary measuring section A from the powder inlet 22. Next, the powder container 1 is returned and erected as shown in FIG. Then, the powder S flowing into the temporary measuring section A flows into the measuring section B,
Excess powder S returns from the powder inlet 22 into the powder container 1. Next, when the powder container 1 is tilted again, as shown in FIG.
Through the powder outlet 41. At this time,
The powder S to be dispensed at the next powder dispensing is measured in the temporary weighing section A. After the powder S measured in the measuring section B is spouted from the powder outlet 41,
When the powder container 1 is returned to the upright state, the powder S measured in the temporary measuring section A flows into the measuring section B, and excess powder S returns into the powder container 1 from the powder inlet 22. . In this way, after the next powder spouting, the powder container 1 is spun out only once so that a fixed amount of the powder S defined by the volume of the measuring section B is spouted out.

In the powder weighing machine 10, the volume of the weighing section B can be changed stepwise by sliding the cap section 40 at the attachment section between the cap section 40 and the cup section 20 as described above. Therefore, the cap portion 4 is attached to the cap portion 40 by attaching the cap portion 20 to the cup portion 20.
The swing amount can be easily adjusted by a simple operation of sliding 0. When the volume of the weighing unit B is increased or decreased by the slide operation, the volume of the tentative weighing unit A is also increased or decreased. Accordingly, the relationship that the volume of the tentative weighing unit A is always larger than the volume of the weighing unit B is set. Therefore, it is possible to maintain high weighing accuracy.

When adjusting the amount to be swung by the powder weighing device 10, the amount of sliding at the mounting portion between the cap portion 40 and the cup portion 20 is adjusted. By appropriately setting the width in the height direction of the attachment portion to the portion 20, the amount can be set to an arbitrary amount, and there is no particular limitation on the mechanism of the powder weighing device 10. Therefore, the adjustment width can be increased. Further, the volume occupied by the cup 20 in the powder container 1 is constant regardless of the amount of sliding at the attachment portion between the cap 40 and the cup 20. Therefore, according to the powder measuring device 10, the powder container 1 can be completely filled with the powder S irrespective of the adjustment amount of the dispensing amount.

Although the powder weighing device 10 of the embodiment shown in FIGS. 1 to 4 has been described above, the present invention can take various other forms. For example, as in the powder weighing device 11 shown in FIG. 5, the cap portion 40 and the partition plate portion 30 are formed of different members, and the partition plate portion 30 is moved in accordance with the vertical movement of the cap portion 40 with respect to the cup portion 20. The cap section 40 and the partition plate section 30 may be bonded so that the cap section 40 also moves up and down. Further, the amount of vertical sliding of the cap portion 40 with respect to the cup portion 20 may be changed continuously instead of stepwise.

The shapes of the cup part 20, the partition plate part 30, and the cap part 40 are various as long as the provisional weighing part A, the weighing part B, and the discharge channel C are formed inside the powder weighing machine by the combination of these. Can be taken. For example, FIG.
In the powder weighing machine 10 according to the embodiment shown in FIGS. 4 to 4, the partition plate portion 30 is formed of a single plate-shaped member hanging down in the cup portion 20, but as shown in FIG. The portion 30 is bent, and the partition plate portion 30p of the portion from the measuring portion B to the discharge channel C and the partition plate portion 30q of the portion from the middle of the discharge channel C to the powder discharge port 41 are inclined. Is also good. As a result, the amount that can be measured can be increased.

There are no particular restrictions on the powder that can be measured and spouted out by the powder meter of the present invention, and examples thereof include powder detergents, powder bleaching agents, powdered foods, and powder seasonings. .
