Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a stopper for quantitatively discharging the contents of powder or granules.

[Conventional technology]

Conventionally, this type of plug was made in 19461.
There is something like the one shown in the number. This consists of a hollow cylindrical primary powder receptacle with the same diameter as the bottle opening and a brim around it, and a bottomed cylindrical primary powder receptacle with a diameter smaller than the diameter of the primary powder receptacle. A powder metering receiver is connected to a secondary powder receiver by several powder receiver supports provided on the periphery of each, and the powder dispenser of a disk having a powder dispenser in the center has the same diameter as the dispenser. A dispenser receiver is provided with a funnel-shaped receiver having a leg portion 7 having a diameter smaller than the diameter of the secondary powder receiver. The powder container is fitted onto the inner side of the powder container, and by first inverting the bottle and putting the powder in the bottle into the first container, and then returning the bottle to its original position, the first container can be removed.
Of the powder that has entered the secondary receiver, the powder within an area corresponding to the area of the secondary receiver is dropped into the secondary receiver,
The powder is dispensed from the dispenser through the dispenser.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional technology, since the diameter of the lower end of the funnel-shaped receiver is smaller than the diameter of the secondary powder receiver, there is a large gap between the lower end of the funnel and the inner surface of the secondary powder receiver. Can be done. Therefore, there is a high possibility that the powder that has entered the secondary powder receiver will return to the bottle through the above-mentioned gap even if the bottle is slightly tilted, making it impossible to measure accurately. There is a problem.

[Means for solving problems]

The present invention has been devised to solve the above-mentioned problems of the conventional technology and to eliminate as much as possible the return of the contents into the container when discharging the contents that have entered the measuring section. a circumferential wall that mates with the
It consists of an upper cover plate having an outlet in the center, a cylindrical wall connected to the outlet, and a dividing plate connected to the upper cover plate, the cylindrical wall, and the circumferential wall, and an extended lower end of the dividing plate. The intermediate part connected to the cylindrical wall has an opening having the same diameter or less as the inner diameter of the cylindrical wall, and a sloping plate extending diagonally upward and a ceiling wall diagonally downward, and the upper end of the slanting plate is connected to the dividing plate. A rising wall that fits with the lower end of the
Further, a cup portion is connected to the lower end of the ceiling wall.

[Effect]

The quantitative stopper of the present invention is inserted into the opening of the container from the cup portion, and the upper cover plate is locked and fixed at the end of the opening. When the container is tilted, the contents inside the container move toward the opening, and flow from the inlet formed between the circumferential wall and the rising wall into the measuring chamber formed by the cylindrical wall, the top cover plate, and the circumferential wall. The amount used per time is measured. At this time, the contents are dispersed almost uniformly by the dividing plate provided in the measuring chamber without being concentrated in a specific part. Next, when the container is returned to its original vertical position, the contents that have entered the measuring chamber are guided by a rising wall and an inclined plate that is connected diagonally upward from an opening with the same diameter or less as the inner diameter of the container. Move to the cup. Then, when the container is tilted again, the contents inside the cup part are discharged through the cylinder wall from the opening having the same diameter or less as the inner diameter of the cylinder wall and through the discharge port while being guided by the ceiling wall connected diagonally downward. be done. At this time, the contents in the container move toward the opening and enter the measuring chamber through the inlet, as in the case of the beginning of use. Therefore, the contents can be easily measured and discharged by simply repeating the same operation thereafter.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, the main body includes a circumferential wall 6 that fits into the opening of the container B, an upper cover plate 4 having a discharge port a in the center, and a cylindrical wall 5 connected to the discharge port a. , and a partition plate 7 connected to the upper cover plate 4, the cylinder wall 5, and the circumferential wall 6, and the intermediate part 2 connected to the extended lower end of the partition plate 7 has the same inner diameter as the cylinder wall 5. An inclined plate 10 is connected diagonally upward and a ceiling wall 12 is connected diagonally downward from the opening b, which is less than or equal to the diameter of the inclined plate 10.
A rising wall 11 that fits into the lower end of the partition plate 7 is connected to the upper end, and a cup portion 3 is connected to the lower end of the ceiling wall 12.

To explain each part in more detail, as shown in FIG. A reinforcing wall 17 is provided on the outside of the dividing plate 7. Further, the cylindrical wall 5 is provided longer downwardly than the partition plate 7.

The intermediate portion 2 has an inclined plate 10 extending upward at a specific angle from an opening 6 having a diameter equal to or smaller than the inner diameter of the cylinder wall 5, and a rising wall 11 connected to the tip thereof. A portion of the separation chamber c is formed below the opening b, and includes a ceiling wall 12 extending downward and an annular wall 13 connected to the cup 3 connected to the tip thereof. An annular rib 1 that fits into the recess 9 is provided in the upper part of the rising wall 11.
4, and an annular recess 15 is provided in the annular wall 13 so as to fit into an annular protrusion 16 provided on the cup 3 to prevent it from falling off.

FIG. 2 is an explanatory view showing a partial cross section of the quantitative stopper A when the container B is tilted.

The contents in the container B flow from the inlet d provided between the circumferential wall 6 and the rising wall 11 into the measuring chamber e surrounded by the cylindrical wall 5, the upper cover plate 4, and the circumferential wall 6. Get into it. The volume of this measuring chamber e is the original volume of the discharge amount, and if there is no loss on the way to discharge, it is sufficient that the volume is equal to the volume of the discharge amount. However, in reality, in the process of returning the container B to its original upright state, it is inevitable that the contents in the measuring chamber e spill out from the inflow port d and return into the container B. In order to reduce this return amount as much as possible, the metering stopper A of the present invention connects the metering chamber e to the inflow port d,
The partition plates 7 extending to the rising wall 11 are arranged in series to achieve a great effect. To explain in more detail, this metering stopper A is intended to be used in the most universal cylindrical container, and does not impose any restrictions on the discharge method and does not give directionality to the discharge operation. It is placed in the center of A. Therefore, the measuring chamber e originally has a donut shape, and the contents that have entered the measuring chamber e are returned to the original vertical position in the process of returning the container B to its original vertical position. As shown in the explanatory diagram showing the movement of the contents, the contents in the upper part of the measuring chamber e slide down, and then the contents in the container B
In the process of changing from a horizontal to a vertical state, most of the contents that have moved downward into the measuring chamber e will flow out from the inlet d into the downward direction of the container B together with the contents in the container B. The dividing plate 7 provided on the metering stopper A solves this inconvenience, and as shown in the explanatory diagram of FIG. , the contents located above the measuring chamber e are prevented from moving downward, and most of the contents in the measuring chamber e are surrounded by the rising wall 11, the inclined plate 10, and the cylindrical wall 5. It serves to guide the air to the space f. In this embodiment, eight dividing plates 7 are provided at equal intervals as shown in FIG. The number decreases depending on the thickness of the partition plate 7, and eight pieces is appropriate. Furthermore, the distance between the inflow ports d, that is, the circumferential wall 6
The wider the gap between the rising wall 11 and the container, the faster the contents will enter the measuring chamber e, but conversely, the amount that will come out into the container will also increase. Therefore, the interval between the inlet ports d is such that the contents in the separation chamber C finish flowing into the measuring chamber e from the time when the container B is tilted until the contents in the separation chamber C finish coming out from the outlet a. is preferred, and this varies depending on the contents. In this example, the contents are
For granules having an irregular size of 0.3 mm to 3.5 mm, the volume of the measuring chamber e was approximately 16 cm ³ and the interval between the inlet ports d was suitably 5 to 6 mm. Another point to reduce the above-mentioned return amount is the space f
is the volume of When the container B is returned from the discharged state to its original vertical state, the contents in the measuring chamber e fall into the space f. Below this space f, as shown in FIG. 1, the lower end of the cylinder wall 5 and the inclined plate 1
Because the annular slit g formed by In other words, it stops at the space f.

At this time, if the volume of the contents in the measuring chamber e is larger than the volume of the space f, the surplus will return to the container B from the inlet d. The reason why the intervals between the annular slits g are narrowed will be described later, and it is necessary that most of the contents in the measuring chamber e be contained in the space f, and the process of returning the container B to its original vertical state is necessary. Even if a part of the contents passing through the annular slit g is taken into consideration, the volume of the space f needs to be 80% or more of the volume of the measuring chamber e. The dividing plate 7 is provided as described above, and the interval between the inflow ports d is narrowed to the necessary minimum,
By setting the volume of the space f to 80% or more of the volume of the measuring chamber e, backflow of the contents from the inflow port d can be suppressed as much as possible, and most of the contents in the measuring chamber e can be separated as described above. It became possible to guide the patient into room c.

Next, the annular slit g is where the loss occurs during the process up to discharge. While the container B is tilted and the contents in the separation chamber C are led to the discharge port a, a portion of the contents will return from the slit g to the space f, and it is necessary to suppress the amount of this return as much as possible. There is. For this purpose, firstly, the interval between the annular slits g should be made as small as possible, and secondly, the diameter of the opening b should be equal to or less than the inner diameter of the lower end of the cylinder wall 5, and FIG. It is necessary that the volume of C is sufficiently larger than the amount (volume) to be discharged.

The smaller the interval between the annular slits g, the smaller the amount of leakage and the smaller the variation in the amount of discharge.
The speed of entry into the separation chamber C from the space f becomes slow. In this embodiment, the speed of entry into the separation chamber C is determined from the inflow port d at the time of discharge to the metering chamber e.
The interval between the annular slits g was set to about 3 mm since there is no time limit such as the rate at which the contents enter the chamber (because the purpose is to discharge one dose in one operation). Further, the separation chamber C was made into a bolt shape, and the diameter of the opening b was narrowed to the same diameter as the inner diameter of the cylinder wall 5, and the diameter of the cup portion 3 was made close to the inner diameter of the opening of the container B. The volume of the separation chamber C needs to be larger than the volume to be discharged, and if it is sufficiently large, the contents in the separation chamber C will not come out from the opening b unless the container B is tilted to a certain extent during discharge. Due to the inertia of the discharge operation and the large tilt, the annular slit g becomes apparently narrower, and the contents move beyond the annular slit g to the discharge port a, and from the annular slit g to the space f. The amount of spillage is greatly reduced. Similarly, the same effect can be expected if the cylindrical separation chamber c has the same diameter as the opening b and is longer in length, but the container B
To attach it to an opening requires a head space corresponding to its length, and if the contents are powder or granules, it is difficult to push out the contents and seal. In this embodiment, by making the separation chamber c into a bolt shape, the container B
The volume of the separation chamber c was set to 1.25 times the volume of the amount to be discharged. In this way, the loss from the annular slit g during the process from the vertical state of the container B to the nearly inverted state of the discharge state is the loss from the narrow annular slit g and the cylindrical wall 5.
The separation chamber c having the opening b smaller than the inner diameter and the volume of the separation chamber c equal to 1.2 of the volume of the amount to be discharged.
By more than doubling it, the amount becomes extremely small, and the efficiency is very high for a metering stopper with a structure in which the flow path of the contents is always open, and more than 82% of the volume of the measuring chamber e can be obtained as a discharge amount. . In addition, the rising wall 11
By increasing the width of the slit g, the distance from the slit g to the inlet d becomes longer, so that even if the container B is knocked over, a portion of the contents in the separation chamber c will flow from the slit g to the space f. Since the liquid only enters the inside of the container B and does not come out into the container B, when the container B is returned to the vertical position, it returns to the separation chamber c, which has the advantage of not affecting the next discharge.

[Effect of idea]

As described above, this metering stopper A has a discharge port a in the center.
It consists of a main body part 1 having a measuring chamber e in which a dividing plate 7 is arranged in series on the upper cover plate 4 side around the main body part 1, and an intermediate part 2 provided at an extended end of the dividing plate 7, and the intermediate part is
An inclined plate is connected diagonally upward from the opening having the same diameter or less as the inner diameter of the cylindrical wall, and a ceiling wall is connected diagonally downward, and the upper end of the inclined plate is a rising wall that fits with the lower end of the partition plate. It has a simple structure in which a cup is connected to the lower end of the ceiling wall, and the captured contents in the measuring chamber e are efficiently guided to the discharge port a, resulting in a stable discharge amount. If the volume of the measuring chamber e is varied by a structure such as doubling the upper cover plate, the discharge amount can be varied and the range of applications will be expanded. In addition, the method of operating this metering stopper is as simple as tilting the container with this metering stopper attached and returning it to its original vertical position, allowing relatively accurate metered discharge, and there is no restriction on the direction in which the container can be tilted. It is a highly practical metering stopper with extremely excellent functions such as being able to be used continuously many times.
