Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a quantitative dispensing container capable of dispensing a predetermined amount of contents such as powdery or granular cosmetics and seasonings in one operation.

《Prior art and its problems》 As a quantitative dispensing container of this type, conventionally, a measuring wall was provided inside the container body, and when the container body was tilted in the inverted direction to discharge the contents, It is known that the amount to be discharged is measured, but since the amount to be measured changes depending on the inclination of the container body, an accurate quantification can be performed especially when the remaining amount of the content is low. I couldn't do it.

Therefore, as shown in Japanese Utility Model Laid-Open No. 58-163484, the bottom surface of the container in the container body is an inclined surface that descends toward the center, and a measuring chamber is provided in the center of this inclined surface to While allowing the contents to flow into the measuring chamber while standing upright, a tubular discharge member integrally formed with the neck and biased downward by a spring is arranged above the measuring chamber, and the cap is capped from the neck. When the discharge member is removed, the discharge member descends and its lower end edge abuts against the upper end edge of the measuring chamber, which shuts off the measuring chamber from the accommodating portion, and the contents of the measuring chamber are discharged by tilting the container body. It has been proposed that it be taken out through the. However, in the case of the container disclosed in the publication, not only the accommodating part and the measuring chamber but also the accommodating part and the discharge member are communicated with each other when the cap is fitted. When the container flows up into the discharge member and then the container is erected and the cap is removed, more content than the amount filled in the measuring chamber is discharged. Therefore, when the container is accidentally laid down or when it is carried in a handbag or the like, it is inconvenient because an accurate quantification cannot be made. Further, since the discharging member cannot be kept airtight between the discharging member and the container body, and thus the container has an O-ring around the discharging member, the spring prevents the discharging member from sliding. In order to obtain sufficient airtightness without using the O-ring and the portion where the O-ring is disposed, a high degree of dimensional accuracy is required, and as a result, there is a problem that the yield of the product is reduced.

The present invention has been made in view of the above-described circumstances, and its purpose is to be able to always take out a predetermined amount of contents accurately, and to hermetically seal the inside of the container body without requiring strict dimensional accuracy. (EN) It is possible to provide a container for quantitatively measuring powder and granules, which can be kept and whose contents are not altered by moisture.

<< Means for Solving the Problems >> A container for extracting a fixed quantity of granular material according to the present invention for achieving the above-mentioned object is provided in a container main body having an opening neck part to which a cap is attached at the upper end, from the bottom part thereof. A discharge passage formed so as to communicate over the opening neck portion and having a narrow width portion formed in the middle, and airtightly attached to the bottom portion of the container body, sequentially enclosing the lower end of the discharge passage from the outside toward the bottom. A lower lid having an inclined surface that is inclined and a cylindrical chamber that is formed at the lower end of the inclined surface so as to be continuous with it, and a lower lid that is movable in the vertical direction in the cylindrical chamber and is moved downward. And a cup-shaped measuring member that is in communication with the inside of the container body via the inclined surface and that is moved upward to be cut off from the inside of the container body and contact the lower end of the discharge path, and below the measuring member. Is installed in the And a convex portion is formed in the middle of the discharge neck so as to be vertically movable from the opening neck portion to the measuring member and is moved downward to move the measuring member downward and the convex portion. And a slide rod that closes the narrow portion of the discharge path and is moved upward to open the discharge path.
A protrusion that pushes the slide rod downward against the biasing means when the cap is closed.

<Operation> To explain the operation of the present invention, when the cap is closed, the protrusion keeps the slide rod moving downward, and the protrusion of the slide rod and the narrow portion of the discharge passage discharge the slide rod. The passage is closed and the measuring member is moved downward against the elastic means.
In this state, since the discharge passage is closed, even if the container body is tilted or tilted, the granular material does not enter the discharge passage. Therefore, the granular material is always supplied to the discharge passage in an amount measured by the measuring member, and a predetermined amount of the granular material can always be taken out. Further, as a structure for hermetically sealing the inside of the container body, the measuring member and the lower lid provided with this are configured separately, and the lower lid that does not need to be moved is attached to the container body. It can be easily and airtightly mounted, and thus the powder or granular material can be reliably sealed in the container body.

When taking out the powder or granular material, if the container body is erected with the cap closed when taking out the powder, the slide bar is moved downward by the projection of the cap and the weighing member also resists the elastic means. Since it is moved downward, the measuring member is communicated with the inside of the container body, and the granular material in the container body flows into the measuring member in the cylindrical chamber through the inclined surface of the lower lid. Then, when the cap is opened, both the slide rod and the measuring member, which have been moved downward until then, move upward by the elastic means, and accordingly, the measuring member and the lower end of the discharge path come into contact with each other so that the measuring member becomes a container. Shut off from inside the body. As a result, only the powder or granules contained in the weighing member and weighed are supplied to the discharge passage. At this time, the discharge passage is opened. That is, by opening the cap in a state where the container body is upright, the measuring member and the inside of the container body are shut off, and the powder and granules can be quantified. After that, if the container is turned upside down, only the powder or granular material measured by the measuring member can be picked up by one operation. Then, when the cap is closed again, the slide rod and the measuring member are moved downward, the discharge path is closed, and the granular material flows into the measuring member from the inside of the container body through the inclined surface to prepare for the next removal. Will be done.

<< Embodiment >> A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In this embodiment, basically, a container body 1 having an opening neck portion 2 to which a cap 21 is attached is formed so as to communicate from the bottom portion to the opening neck portion 2 and a narrow portion 6 is formed in the middle portion. The discharge passage 4 formed with a groove, and the slope 12 and the bottom of the slope 12 which are airtightly attached to the bottom of the container body 1 and surround the lower end of the discharge passage 4 from the outside toward the lower side.

The cup-shaped measuring member 15 which is in communication with the container, is moved upward, is cut off from the inside of the container body 1, and contacts the lower end of the discharge path 4.
And a spring 17 provided below the measuring member 15 as an elastic means for elastically urging the measuring member 15 upward, and provided in the discharge path 4 so as to be vertically movable from the opening neck 2 to the measuring member 15. At the same time, a convex portion 7 is formed at an intermediate portion and is moved downward to move the measuring member 15 downward, and at the same time, the convex portion 7 closes the narrow portion 6 of the discharge passage 4 and is moved upward to open the discharge passage 4. The slide rod 5 and the cap 21 are provided with a projection 24 provided on the cap 21 to push down the slide rod 5 against the spring 17 when the cap is closed.

FIG. 1 shows a container for quantitatively measuring powder and granules according to an embodiment of the present invention. In the figure, reference numeral 1 is a substantially cylindrical container body, and an open neck portion 2 is provided at the center of the upper end of the container body. On the other hand, its lower end is open. An annular wall 3 having the same diameter and the same diameter as the neck portion 2 is hung from the inside of the upper end surface of the container body 1 to define a discharge passage 4 communicating with the opening of the neck portion 2. Also, a slide rod 5 having a sufficiently small diameter is arranged. Near the lower edge of the discharge passage 4 is a narrow portion 6 due to the rib of the annular wall 3, and when the slide rod 5 is at the lower position shown in FIG. 1, the convex portion 7 formed on this slide rod becomes the rib. It abuts and closes the narrow portion 6, whereby the discharge passage 4 is blocked from the housing portion 8 on the outside thereof. The accommodating portion 8 is filled with powdery or granular contents. The lower lid 9 attached to the lower end of the opening of the container body 1 includes a disc-shaped bottom plate 10, a peripheral wall 11 projecting upward from a central portion of the bottom plate 10, and an outward direction from an upper edge of the peripheral wall 11. A flange 13 having an inclined surface 12 extending obliquely upward is integrally formed, and the inclined surface 12 faces the housing portion 8.

A measuring member 15 is fitted in a cylindrical chamber 14 defined by the peripheral wall 11 so as to be slidable in the vertical direction. The measuring member 15 is formed in a cylindrical shape with an open upper end, and is operated once. A little less than the predetermined amount to be discharged at, that is, strictly speaking, the amount of the content obtained by subtracting the space volume between the lower end edge of the annular wall 3 and the upper end edge of the measuring member 15 from the predetermined amount. Has become. While the lower end small diameter portion 5a of the slide rod 5 is integrally fixed to the recess 16 provided on the bottom surface of the measuring member 15,
A spring 17 is arranged between the bottom surface and the bottom plate 10 to constantly urge the measuring member 15 upward. The peripheral portion of the bottom plate 10 is integrally and airtightly fixed to the inner surface of the container body 1 by concave-convex fitting. Further, in this embodiment, an O-ring 19 is arranged in a groove 18 formed in the peripheral end surface of the flange 13. The O-ring 19 is brought into pressure contact with the inner surface of the container body, so that the airtightness of the housing portion 8 is further ensured.

A screw thread 20 is formed on the outer peripheral surface of the neck portion 2 of the container body 1 so as to be screwed with a screw thread 22 on the inner surface of the cap 21. The inner peripheral wall 23 provided is in close contact with the inner surface of the neck portion 2, and the projection 24 hanging down from the center of the top surface abuts on the upper end surface of the slide rod 5 and the slide rod and the measuring member 15 are shown against the spring 17 as shown. Is pressed to the lower position.

Next, at the time of use, as shown in FIG. 2, the cap 21 is removed and the neck portion 2 is opened. Then, the slide rod 5 and the measuring member 15 released from the pressing force of the protrusion 24 are spring-loaded.
By the action of 17, the convex portion 7 of the slide rod 5 is separated from the rib of the annular wall 3 to open the discharge path 4, while the upper end edge of the measuring member 15 contacts the lower end edge of the annular wall 3. The discharge passage 4 and the inside of the measuring member 15 are shut off from the housing portion 8. At this time, the contents existing between the annular wall 3 and the measuring member 15 are taken into the discharge passage 4. Therefore, if the container body 1 is tilted in the inverted direction in this state, only a predetermined amount of contents can be taken out from the neck opening.

In assembling the above-mentioned container, as shown in FIG. 3, the container main body 1 screwed with the cap 21 is inverted, and the contents are filled into the containing portion 8 from the lower end opening, and then the slide rod is inserted.
5. It is sufficient to insert the measuring member 15 and the spring 17 and then fit the lower lid 9, and this procedure is the same when refilling the contents.

4 and 5 show another example of the neck portion and the cap of the container body 1. In the example of FIG. 4, a radial hook-shaped projection 30 is provided on the outer peripheral surface of the neck portion 2 and the cap 21 is provided. An intermediate wall 31 is formed to have a large diameter and hangs down from its top surface, and a hook 32 that elastically engages with the protrusion 30 is provided around the inner surface of the intermediate wall, as shown in FIG. By pulling the cap 21 upward, the above engagement is released and the cap is removed. Further, in the example of FIG. 5, the cap 21 is formed in a substantially tubular shape with the upper and lower openings, and the projection 24 abutting on the slide rod 5 is formed into a substantially Y-shaped cross section, and its vertical peripheral edge portion 40 has an inner surface of the neck portion 2. While closing the neck by closely contacting with the cap 24, a large number of through holes 41 are formed in the flange for connection with the peripheral wall of the cap formed at the upper end of the protrusion 24, and the rising position of the cap 21 shown in FIG. A passage is formed from the neck opening through the through hole 41.
The cap 21 is attached so that it can move up and down with respect to the neck by radial fitting or screwing between the inner surface of the peripheral wall and the outer surface of the neck, but it cannot be displaced by the elastic force of the spring 17, and is used during use. You can open and close the container by one-touch operation that only moves up and down without attaching and removing the cap 21.

<Effect of the Invention> As described above, in the present invention, when the cap is closed, the projection keeps the slide rod moving downward, and as a result, the protrusion of the slide rod and the narrow portion of the discharge path are maintained. The discharge passage is closed by and the measuring member is moved downward against the elastic means. In this state, since the discharge passage can be closed, even if the container body is tilted or tilted, the granular material does not enter the discharge passage.
Therefore, the granular material is always supplied to the discharge passage in an amount measured by the measuring member, and a predetermined amount of granular powder can be taken out at all times. Further, as a structure for hermetically sealing the inside of the container body, the measuring member and the lower lid provided with this are configured separately, and the lower lid that does not need to be moved is attached to the container body. It can be easily and airtightly mounted, and thus the powder or granular material can be reliably sealed in the container body.

In the operation of taking out the powder or granules, the powder or granules in the container main body flow into the measuring member in the cylindrical chamber through the inclined surface of the lower lid in a normal state where the container main body is upright. , When the cap is opened to take out the granular material, the measuring member and the lower end of the discharge path come into contact with each other, so that the measuring member can be shielded from the inside of the container body. Only the discharge line can be supplied. That is, by opening the cap in a state where the container body is upright, the measuring member and the inside of the container body are shut off, and the powder and granules can be quantified. After that, if the container is turned upside down, only the powder or granular material measured by the measuring member can be picked up by one operation.
