Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metered-dose container capable of containing a fluid granular material and discharging a fixed amount of the granular material.

[0002]

2. Description of the Related Art As a container for storing granular or powdery granular material such as detergent or bleaching agent, conventionally, by placing the container upside down, the granular material in the container is placed in a weighing chamber provided on a lid. By storing and then putting the container upright, the particles in this measuring chamber were transferred to the storage chamber between the container and the lid, and when the container was inverted again, a certain amount was stored in the storage chamber. There is known a fixed-quantity discharge container capable of repeatedly squeezing a fixed amount of content by discharging a powder or granular material with a simple operation.

The following types of known constant-volume discharge containers are known. As shown in FIG. 6, the powder quantitative container described in Japanese Utility Model Publication No. 42-20606 has a bottomed cylindrical main body 71, and a trapezoidal trap 72 attached to the upper opening of the bottomed cylindrical main body 71. And instrument lid 75
Is provided. The instrument lid 75 includes a ceiling plate 76 and a peripheral wall 77.
A cylindrical partition wall 73 is formed in the center of the ceiling plate 76, and a plurality of discharge holes 74 are formed in the corners of the ceiling plate 76 along the circumferential direction, and the contents of quantitative determination are repeated by simply inverting the entire container. You can take things out.

As shown in FIG. 8, a granular material dispensing device disclosed in Japanese Utility Model Publication No. 45-14716 has a lid member 93 having a tubular skirt portion 91 and a mortar-shaped ceiling plate 92, and It is composed of a container 95 having a small tubular discharge portion 94, is easy to assemble, and has a ceiling plate 92.
It is possible to accurately dispense a predetermined amount of contents through the dispensing passage 96 formed at the corner portion of the.

As shown in FIG. 7, the fixed quantity take-out cap described in Japanese Utility Model Laid-Open No. 52-14840 is provided below the cap body 83 having a fixed quantity pan 81 and a contents take-out port 82 on its side. A cap 84 is provided.

[0006] In each of the containers and the constant-volume discharge device described above, a fixed amount of powder or granular material is dispensed into the measuring chamber of the lid member by inversion, and the powder or granular material dispensed when upright is transferred to the storage chamber. The powder or granular material in the storage chamber is ejected from the ejection port when it is inverted again. However, since these containers do not have a cover for closing the discharge port, moisture and dust easily enter, and there is a problem that the contents spill out from the discharge port when the container is dropped or tumbled by mistake. Further, it is extremely difficult structurally to replenish or refill the powder or granules in the container, and thus they cannot be practically used as a refill container.

A fixed-quantity discharge container having a cover at the discharge port is also known. In the fixed-quantity shaking container described in Japanese Utility Model Publication No. 3-38133, as shown in FIG. 4, a cap 47 is detachably fitted into an opening 46 of a container body 45, and the cap 47 and the main cylinder member 51 Cover member 5 to cover
2 and a small-diameter member 53 with a measuring tube provided inside the main tubular member 51. The main tubular member 51 and the lid member 5 are provided.
2 and 3 are connected via a three-point hinge mechanism. With this structure, the entire container is formed of two members, the container body 45 and the cap 47, and it is easy to refill and refill the contents of the container and assemble this container.

As shown in FIG. 5, the dispensing package described in Japanese Patent Laid-Open No. 3-226465 discloses a container 60 having an inclined shoulder portion 61 and a neck portion 62, an inner skirt 63 surrounding the neck portion 62, and an outer skirt. It is composed of a cap 65 having 64, and is easy to manufacture, has a small dispensing volume of the contents, and can easily change the dispensing volume.

[0009]

However, in any of the above-described constant-quantity discharge containers, the discharge amount varies each time due to, for example, the tilt angle at the time of inversion and the acceleration of swinging, and the outflow does not stop even while returning to the upright state. A phenomenon, that is, a so-called "poor powder cutting" occurred, which was inconvenient.

The present invention has been made in order to solve the above problems, and therefore an object thereof is to provide good quantitativeness of the discharge amount each time the powder particles are discharged in an inverted manner. Another object of the present invention is to provide a constant-quantity discharge container which is excellent in powder breakage.

[0011]

In order to solve the above-mentioned problems, the present invention includes a bottomed cylindrical container main body having a container opening for accommodating the powder and granules and having the container opening at the top. And a container-equipped fixed-quantity discharge part attached to the container main body, and the container opening is an opening cylinder whose mouth edge portion extends upward in the constant-quantity discharge part to form a spout of powder or granules. The fixed amount discharge part is connected to the bottom plate part extending outward from the base part of the opening cylinder, the outer cylinder part that rises upward from the peripheral edge part of the bottom plate part, and the upper surface of the outer cylinder part. A top plate portion arranged so as not to come into contact with the upper end portion of the tubular body, and from the lower surface of the top plate portion so as not to come into contact with any of the outer tubular portion, the bottom plate portion and the open tubular body, and Cylindrical scar that overlaps the opening cylinder with a gap width W over a certain overlap length L Part is suspended, also of the top plate portion,
A powdery or granular discharge port is formed between the outer cylinder part and the skirt part, and the ratio (L / W) of the overlapping length L to the gap width W between the skirt part and the opening cylinder is 1.0. Provided is a metered-dose container having a dose within a range of to 3.0.

The present invention also provides, in the above, a constant-volume discharge container in which a baffle plate whose surface is directed toward the discharge port is attached inside the opening cylinder so as not to contact the top plate portion. In this case, it is preferable that the upper end of the baffle plate is attached so as to project from the opening cylindrical body.

It is preferable that the fixed amount discharge container is detachably mounted on the container body. Further, it is preferable that a cap that can be opened and closed is attached to the discharge port.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show an embodiment of a fixed-quantity discharge container according to the present invention. A fixed-quantity discharge container 1 exemplified here is a container body 2 having a substantially bottomed cylindrical shape,
The container main body 2 is composed of a fixed quantity discharge part 4 which is detachably screwed to the upper part of the container body 2 by a screw part 3a.

The container body 2 is a container made of synthetic resin, glass or the like, and contains fluid powder particles such as detergent and bleaching agent inside the container opening 3 in the upper part. The constant-quantity discharge part 4 is formed to have the same outer diameter as the container body 2, and the constant-quantity discharge container 1 has a cylindrical appearance as a whole.

The fixed-quantity discharge part 4 is a cylindrical molded product with a lid formed of synthetic resin or the like, and is roughly composed of a bottom member 15, an outer cylinder part 7, and a top plate part 10. Bottom member 1
Reference numeral 5 denotes a cylindrical opening tubular body 18 which is formed in the central portion thereof and extends upward in the fixed amount discharge portion 4, and a bottom plate portion 16 which extends outward from the base portion thereof. 3 is connected to the rim portion to form a pouring port C for the granular material.

The outer cylinder portion 7 extends upward from the peripheral edge portion of the bottom plate portion 16 to form an outer peripheral wall of the fixed quantity discharge portion 4. The top plate portion 10 is a lid member that covers the upper surface of the outer tubular portion 18 and that is arranged so as not to contact the upper end portion of the opening tubular body 18.

From the lower surface of the top plate portion 10 described above, the opening cylindrical body 1
A cylindrical skirt portion 12 is hung down concentrically with 8. The skirt portion 12 extends downward so as not to come into contact with any of the outer tubular portion 7, the bottom plate portion 16 and the opening tubular body 18, and has a constant overlapping length L with the opening tubular body 18 with a gap width W therebetween.
They are arranged so as to overlap each other.

Hereinafter, the space formed by the top plate portion 10 and the inner side of the skirt portion 12 will be referred to as "measuring chamber B", and the gap between the skirt portion 12 and the opening tubular body 18 will be referred to as "gap D".
The space formed between the outer cylinder portion 7 and the skirt portion 12 is referred to as "reservoir A".

The outer cylinder portion 7 and the skirt portion 12 of the top plate portion 10
Between, and, that is, on the upper surface of the storage chamber A, a discharge port 13 for the granular material is formed. Further, the discharge port 13 has
Openable and closable cap 8 is hinge 20 and connecting piece 8a.
It is attached to open and close freely.

In the constitution of the constant amount discharge section 4, the ratio (L / W) of the overlapping length L of the gap D to the gap width W is
It is set within the range of 1.0 to 3.0, for example, 1.5.
As this ratio (L / W) (hereinafter referred to as “narrowness”) increases, the flow resistance of the powder or granular material passing through the gap D increases, and it becomes difficult to pass.

Further, a baffle plate 9 is attached to the inside of the opening cylinder 18 so as to extend vertically over its inner diameter. The baffle plate 9 is attached so as to project from the opening tubular body 18 so that the upper end thereof does not come into contact with the top plate portion 10, and the surface of the baffle plate 9 faces the discharge port 13 side.

Next, a usage pattern of the constant volume discharge container 1 will be described with reference to FIGS. 3 (a), 3 (b) and 3 (c). First, in order to fill the fixed quantity discharge container 1 with a powder or granular material such as a detergent, the screw part 3a is rotated to rotate the container main body 2 and the fixed quantity discharge part 4.
Are separated from each other, and the container main body 2 is filled with the powder or granular material through the container opening 3 having a large opening, and then the container main body 2 and the fixed amount discharge part 4 are screwed together.

In the case of quantitatively discharging the contents of the fixed quantity discharge container 1 filled with the granular material, as shown in FIG. 3 (a), first, the fixed quantity discharge container 1 is closed at the bottom with the cap 8 closed. Turn it upside down. By this operation, the container body 2
The powder particles inside pass through the spout C, fall, and flow into the measuring chamber B. At this time, the narrowness (L / W) of the gap D is 1.
Since it is set to 0 or more and a proper flow resistance is imparted to the granular material passing through the gap D, the granular material does not pass through the gap D and overflow into the storage chamber A, and the measuring chamber B is filled. In this state, the fall of the powder or granular material from the container body 2 is naturally stopped. Therefore,
The volume of the powder or granular material flowing into the measuring chamber B is always constant.

Subsequently, when the fixed amount discharge container 1 is erected,
As shown in FIG. 3B, the granular material filled in the measuring chamber B flows down into the storage chamber A through the gap D. At this time, the narrowness (L / W) of the gap D is set to 3.0 or less, and the flow resistance of the powder or granules passing through the gap D is not excessive.
The powder or granular material does not remain in the measuring chamber B, and the powder or granular material measured in the measuring chamber B is quantitatively transferred to the storage chamber A. At this time, since the baffle plate 9 is attached to the spout C,
The backflow to the container body 2 is suppressed, and the above-mentioned quantitativeness is further improved.

In this state, the cap 8 is opened, and as shown in FIG.
As shown in, when the fixed-quantity discharge container 1 is turned over or tilted, the powder or granular material stored in the storage chamber A is discharged from the discharge port 13. At this time, the granular material in the container body 2 flows into the measuring chamber B from the spout C. However, in this overturned or inclined state, since the baffle plate 9 with the surface facing the discharge port 13 side is attached to the spout C, the outflow amount of the powder or granules flowing out from the spout C is limited. Moreover, since the outflow is suppressed by the gap D, it does not overflow into the storage chamber A.

Therefore, only the granular material stored in the storage chamber A by the first inverted-upright operation is discharged from the discharge port 13, and the quantitativeness of the discharge amount is ensured and
A so-called "poor powder breakage" phenomenon, in which excessive powder or granules spill out on the way from the inclined state to the upright state, is avoided.

Next, the structure of the constant amount discharge part 4 in the constant amount discharge container of the embodiment will be described in detail. In FIG. 1, the fixed amount discharge part 4 is composed of an inner cylinder member 5, an outer cylinder member 6, a cap 8 and a baffle plate 9. Outer cylinder member 6
Is a cylindrical body forming the outer peripheral wall 14 of the outer tubular portion 7,
A bottom member 15 composed of an opening cylinder 18 and a bottom plate portion 16 is integrally molded in the middle portion of the inner peripheral surface thereof, and a screw threaded with the screw portion 3a at the peripheral edge of the container opening 3 is formed on the inner peripheral surface of the lower end portion. Is molded.

The inner cylinder member 5 is composed of a cylindrical part 11 fitted in the upper inner peripheral surface of the outer cylinder part 6 in the outer cylinder part 7, and a top plate part 10 integrally formed at the upper end thereof. This top plate 1
A skirt portion 12 is integrally hung from 0 to the inside of the cylindrical portion 11. At this time, the diameter and length of each of the skirt portion 12 and the opening tubular body 18 ensure the discharge amount required by the measuring chamber B, and the ratio of the overlapping length L to the gap width W, that is, the narrowness (L / W) is adjusted within the range of 1.0 to 3.0, for example, 1.5. A discharge port 13 is formed in the top plate portion 10 between the cylindrical portion 11 and the skirt portion 12.

The cap 8 is formed in such a shape as to cover the entire top plate portion 10, and is attached to the upper end portion of the outer tubular member 6 via a hinge 20 provided at a position away from the discharge port 13 so that the cap 8 can swing freely. ing. By this, this cap 8
It is possible to swing from the closed state shown in FIG. 1 to the open state shown by the two-dot chain line in the figure. A cylindrical contact ring 21 is formed on the lower surface of the cap 8 at a position where the discharge port 13 is tightly sealed when closed.

In this example, the V-shaped connecting piece 8a is used.
, One end of which is attached to the outer surface of the cap 8 and the other end of which is attached to the outer peripheral surface of the outer tubular member 6 via hinges, respectively, and these hinges and the hinge 20 are so-called "three-point hinges". And the cap 8 is in the closed position,
The open position or any of the positions can be binarized.

The baffle plate 9 is a rectangular plate material, the width of which is formed to be equal to the inner diameter of the opening cylinder 18, and the baffle plate 9 is extended in the width direction with the surface facing the discharge port 13 and fixed vertically. ing. The upper end of the baffle plate 9 preferably protrudes upward from the upper end of the opening tubular body 18 within a range where it does not contact the top plate portion 10. This further improves the powder breakage characteristics of the constant-volume discharge container.

In the above-mentioned fixed quantity discharge container 1, the refilling of the powder and granules is carried out by rotating the screw portion 3a to separate the container body 2 and the constant quantity discharge part 4 from the large diameter container opening 3. After filling the container body 2, the container body 2 and the fixed-quantity discharge part 4 may be screwed together, which is extremely easy. Therefore, this fixed-quantity discharge container 1 can be repeatedly used by replenishing powder particles as a container for refilling, which is economical and resource saving.

(Test Example 1) The baffle plate 9 was removed from the constant-quantity discharge container of the above-described embodiment, and a constant-quantity discharge container in which the gap width W of the gap D and the overlapping length L were variously changed was prototyped, and the narrowness ( L
/ W) and the variation in discharge amount were measured.

As for the variation in the discharge amount, after closing the cap 8 and performing one upright-upright operation, the cap 8 is opened.
The volume of the powdery or granular material discharged by one discharge operation of inverting and swinging once was measured, and the average value of the discharge amounts when this discharge operation was repeated 20 times was defined as the average discharge amount (V ₀ ), and The standard deviation of the discharge amount (V _n ) obtained by the discharge operation of ( ₁ ) is divided by the average discharge amount (V ₀ ) and multiplied by 100 to obtain the “variation coefficient”.
Asked. For the judgment, those with a coefficient of variation (%) of 10% or less are indicated by ◯, and those exceeding 10% are indicated by x. The results are shown in Table 1.

[0036]

[Table 1]

From the results shown in Table 1, it is recognized that the coefficient of variation tends to decrease as the narrowness (L / W) increases.
In particular, in Test Nos. 4, 5, 6, 7, 8, 10, and 12 in which the narrowness (L / W) is 1.0 or more, the coefficient of variation is 10% or less and there is little variation (○. ) Was determined.

However, when the narrowness (L / W) becomes too large, although not shown, it is difficult for the granular material to flow out from the measuring chamber B during the inverted-upright operation and is stored in the storage chamber A. It takes a long time to reach the end, which is not preferable. In addition, if the overlapping length L is increased to increase the narrowness, the vertical dimension of the constant volume discharge part 4 becomes long, which is not preferable in the design of the container. From these viewpoints, in the present invention, the narrowness (L / W) is within the range of 1.0 to 3.0. Particularly, the narrowness (L / W) is preferably in the range of 1.4 to 2.0.

(Test Example 2) The effect of the baffle plate 9 was tested.
The baffle plate 9 according to Example 1 was attached to the opening cylinder 18 of the constant-volume discharge container of Sample No. 6 used in Test Example 1, and Test Example 1
The coefficient of variation (%) was obtained in the same manner as in the case of. The result
The results are shown in Table 2 in comparison with Sample No. 6 having the same structure except that the baffle plate 9 is not provided.

[0040]

[Table 2]

From the results shown in Table 2, the fixed-quantity discharge container of Sample No. 13 with the baffle plate 9 attached thereto has the sample No. 6 without the baffle plate.
The coefficient of variation is improved compared to This is because the presence of the baffle plate 9 restricts the flow of the powdery particles and improves the powder cutting property. The quantitative discharge container of Sample No. 13 was judged to be excellent (⊚) due to the improved powder cutting property.

The above embodiment is an example of a preferable fixed amount discharge container of the present invention, but the present invention is not limited to this structure. For example, the cross-sectional shape of the container body, the fixed-quantity discharge portion, the skirt portion as the internal structure, the opening tubular body, etc. may be circular, elliptical, rectangular, or their variations independently or uniformly. .

In the embodiment, the baffle plate is arranged vertically to the inner diameter passing through the center of the opening cylinder, but if the surface is directed toward the discharge port 13, it is attached at a position off the center. May or may not be vertical. Furthermore,
Two or more sheets may be attached, and both sides of these baffle plates do not necessarily have to be joined to the inner wall of the open tubular body.

The fixed-quantity discharge part 4 and the container body 2 may be integrated so as not to be detachable. However, when used as a refill container, it is preferably detachable. In addition to the method using the screw shown in the first embodiment, the joining in the case of being detachable can be performed by forming corresponding concave / convex stripes on the peripheral surface of the joining portion between the constant-quantity discharging portion 4 and the container body 2, respectively. The configuration may be such that they are joined by the engagement of, or a configuration in which a screw and a concave / convex ridge are combined.

The shape and configuration of the cap are not limited to those in the above embodiment. The point is that the discharge port 13 can be closed so that it can be opened and closed freely, so that only the discharge port 13 may be locally covered instead of the entire top plate portion 10. Also, the opening and closing of the cap does not depend on the hinge method but slides. It may be performed by a system or by a separation system such as a stopper.

[0046]

As described above, in the constant volume discharge container of the present invention, the ratio (L / W) of the overlapping length L to the gap width W between the skirt portion and the opening cylinder is 1.0 to 3.0. Since it is within the range, in a series of operations of upside down-upright-drawing, there is no discharge of excess powder or granules, and there is little variation in the discharge amount and smooth discharge is possible. Is obtained. If a baffle with the surface facing the discharge port side is installed inside the opening cylinder so that it does not come into contact with the top plate, excess powder and granules will be used during the return from the inverted state to the upright state. The phenomenon of so-called "poor powder breakage", which spills out, is avoided, and the quantitativeness is further improved. If the fixed-quantity discharge part is detachably attached to the container body, refilling the powder and granules becomes extremely easy and can be repeatedly used as a refill container, which is economical and resource saving.
If a cap that can be opened and closed is attached to the discharge port, it is possible to prevent dust and particles from flowing out and scattering during the swinging operation or inadvertent fall, and to prevent moisture and dust from entering the container. .
