Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a shaker container that is used to shake out powder such as cosmetics or food products, and particularly relates to a shaker container that can prevent clogging. Regarding.

[Prior art]

Generally, there is a container body that houses powder inside and has a thread formed on the outer periphery of the mouth, and a plurality of small containers attached to the tip end of the mouth of the container body to adjust the amount of the powder to be dispensed. An inner stopper with a hole drilled therein, an upper end serving as a canopy to cover the inner plug, and a cylindrical part extending in the axial direction from the outer periphery of the canopy, which is screwed onto the external thread of the container body. Shaking containers consisting of a cap and a cap are known.

In this type of dispenser container, since the inner stopper is covered with a cap, it is possible to prevent dust and the like from entering the container body when the container is not in use. When in use, if you remove the cap, the inner stopper has multiple small holes, so simply turn the container body over and shake it up and down, and the powder inside the container body will be released through each of the small holes. It has the advantage that it can be dispensed in a uniformly dispersed manner.

However, in the case of such a shaker container, when the powder inside the container body is shaken out into hot water, the surrounding water vapor adheres to each small hole in the inner stopper along with the powder, causing clogging. There is a drawback.

In order to improve these shortcomings, for example,
As shown in Japanese Patent No. 52-89382, there is a container that contains powder inside and has a thread formed on the outer periphery of the mouth, and a container that is attached to the tip end of the mouth of the container to adjust the amount of the powder to be dispensed. In order to do this, an inner lid is provided with a plurality of drawing holes, and the upper end side serves as a canopy part to cover the inner lid, and the inner periphery of a cylindrical part extending in the axial direction from the outer periphery of the canopy part is formed. An outer lid that is screwed onto the container via screws, and a mounting that is provided so as to come into contact with the inner surface of the canopy part of the outer lid, and that is rotatably provided on the outer lid via detachment prevention pieces at four locations. A device is known that is constructed of a plate and a plurality of pins that protrude from the inner surface of the mounting plate in the axial direction so as to protrude longer than the cylindrical portion of the outer cover, and are inserted into each of the swing holes. There is.

In the conventional shaker container configured as described above, when the outer lid is placed on the container, the pin provided on the lower surface of the support plate is inserted into the shaker hole, and the powder is moistened to close the shaker hole. The dispenser hole will not become clogged even when the machine is in use.

[Problem that the invention attempts to solve]

However, in the shaker container according to the prior art described above, when the support plate is rotatably supported with respect to the outer lid, it is only supported by four detachment prevention pieces while in contact with the canopy of the outer lid. Furthermore, since these anti-separation pieces are molded by heat and pressure, not only can the support plate not move in the axial direction, but it is also difficult to rotate due to the resistance between each pin and the swinging hole. The problem is that alignment is very difficult. In particular, since the plurality of pins protruding from the support plate are formed to protrude longer in the axial direction than the cylindrical portion of the outer lid, the tips of these pins and the swinging hole must be aligned in advance. Otherwise, there is a problem that the outer lid cannot be screwed onto the mouth of the container.

The present invention was devised in view of the problems of the conventional technology, and it not only prevents clogging of the small hole for shaking out the powder, but also prevents each protrusion from entering the small hole for shaking out when the cap is screwed on. It is an object of the present invention to provide a shaker container that can be guided well.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a container body containing powder inside and having a thread formed on the outer periphery of the mouth part, and a mouth part of the container body. An inner plug is attached to the tip side and has a plurality of small holes concentrically drilled in order to adjust the amount of the powder to be dispensed, and the upper end is a canopy part to cover the inner plug, and the canopy part is attached to the top end. a cap screwed onto the male thread of the container body via a female thread formed on the inner circumferential side of a cylindrical portion extending in the axial direction from the outer circumference; and a disc provided within the cap;
A shaker container comprising a plurality of protrusions that protrude in the axial direction from the back surface of the disc so as to be positioned corresponding to each of the small holes of the inner stopper, and that are capable of fitting with each of the small holes, Each of the protrusions is formed to be sufficiently short compared to the axial length of the cylindrical portion of the cap, and on the inner periphery of the cylindrical portion of the cap, there are annular projections that protrude radially inward from the canopy portion at predetermined intervals in the axial direction. Protrusions are provided,
holding the disc so that it can move axially and rotatably between the annular projection and the canopy of the cap;
A regulating means for regulating relative rotation of the disc with respect to the cap is provided between the outer peripheral side of the disc and the upper surface of the annular projection.

[Effect]

With this structure, when the cap is screwed onto the container body, the relative rotation of the disc is restricted by the rotation restriction means, and the disc rotates integrally with the cap. At this time, since the protrusion protruding from the disk is sufficiently short compared to the axial length of the cap, it does not interfere with the rotation of the cap. Then, when each protrusion of the cap is aligned with a small hole for dispensing drilled in the inner stopper, each protrusion fits into the small hole and the rotation of the disk is stopped, allowing the cap to rotate further. Then, the disc holds its position against the resistance force of the rotation restriction part, and the disc is separated from the rotation restriction part and relatively pushed upward in the axial direction,
When the cap is fastened to the mouth of the container body, each of the protrusions closes the small holes for shaking out, thereby preventing the small holes from clogging when the cap is removed next time.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

1 to 5 show a first embodiment of the invention.

In the figure, reference numeral 1 denotes a container body formed from a resin material or the like into a cylindrical shape with a bottom. Cosmetic powder 2 as a powder is stored in the container body 1, and the upper end of the container body 1 A mouth portion 1A is provided on the side, and a male thread 1B is formed on the outer periphery of the mouth portion 1A. Further, an annular groove 1C is formed on the outer periphery of the tip end of the mouth 1A above the external thread 1B, and the upper annular portion of the groove 1C serves as a mouth edge 1D. Note that the outer diameter of the mouth edge 1D is the same as the mouth 1D.
It is the outer diameter of A. 3 is the opening 1 of the container body 1
An inner stopper attached to the tip side of A, the inner stopper 3 is made of a resin material or the like, and includes a disc-shaped lid part 3A that covers the mouth edge 1D, and a shaft extending from the outer periphery of the lid part 3A. A short cylindrical portion 3B with a thin wall protruding downward.
and an annular protrusion 3C that protrudes radially inward from the inner periphery of the lower end of the cylindrical portion 3, and the protrusion 3C
is fitted into the groove 1C of the container body 1 to prevent the inner stopper 3 from being removed.

4, 4, ... are small holes drilled in the lid 3A of the inner stopper 3 in order to adjust the amount of powder 2 dispensed inside the container body 1. For example, a total of 17 small holes 4 are drilled concentrically and at equal angular intervals, and among the small holes 4, the small hole 4A located in the center has a slightly larger diameter than the other small holes 4. is formed. Further, each of the small holes 4 is tapered toward the lower surface side, and is designed so that each protrusion 10, which will be described later, can easily fit into the small hole 4. Note that the number of each small hole 4 may be determined as appropriate depending on the application; for example, 9
They may be formed in concentric circles and at equal angular intervals.

Reference numeral 5 denotes a cap that is screwed onto the opening 1A of the container body 1. As shown in FIG. A cylindrical portion 5 extending axially downward from
B, and a female screw 5C formed on the inner circumferential surface of the cylindrical portion 5B at a position lower than the intermediate portion thereof and adapted to be screwed into the male screw 1B of the container body 1. Reference numeral 6 denotes an annular projection provided on the upper inner periphery of the cylindrical portion 5B at a predetermined distance from the canopy portion 5A of the cap 5. It is formed in a triangular shape. On the upper inclined surface of the annular projection 6, irregularities 7 having a small depth (height) or a mountain shape are arranged in a row in the circumferential direction. (Figure 4,
(See Figure 5).

Here, the uneven portion 7 is composed of a slope 7A on one side and a slope 7B on the other side, and the angle between the slopes 7A and 7B is an obtuse angle of about 150 degrees. If the male thread 1B and female thread 5C are right-handed threads,
As shown in FIG. 5, one side slope 7A is the other side slope 7B.
For example, the lead angle is the same as or slightly larger than that of the male thread 1B and female thread 5C, so that the lead angle is slightly larger than that of the male thread 1B and the female thread 5C. ). on the other hand,
The lower inclined surface 6A of the annular protrusion 6 is a contact surface for the lid 3A of the inner stopper 3, and when the cap 5 is fastened, the lower inclined surface 6A is brought into contact with the upper surface of the outer circumferential side of the lid 3A. It comes to be touched. Note that the canopy portion 5A of the cap 5 may be formed separately from the cylindrical portion 5B. In this case, the uneven portion 7 can be easily formed, and a disk 8, which will be described later, can be easily assembled. After the disk 8 is assembled, the canopy part 5A and the cylinder part 5B may be integrated by means of adhesive or the like.

Reference numeral 8 denotes a disc that is movable in the axial direction and rotatably held between the canopy part 5A of the cap 5 and the annular projection 6, and the disc 8 has a smaller diameter than the inner circumference of the cylindrical part 5B. It is formed to have a larger diameter than the inner periphery of the annular projection 6, and the lower surface of the outer periphery of the disc 8 is chamfered.
Further, uneven portions 9 corresponding to the uneven portions 7 of the annular projection 6 are arranged in a row in the circumferential direction. The concavo-convex portion 9 together with the concave-convex portion 7 constitutes a regulating means for regulating relative rotation of the disk 8 with respect to the cap 5.
While the disc 8 is in contact with the upper inclined surface of the annular projection 6 due to its own weight, it engages with the concavo-convex portion 7 of the annular projection 6 as shown in FIG. It's getting old. Note that if the disk 8 is made of a soft resin material, the disk 8 can be easily assembled into the position shown in FIG. 3 from the lower side of the cylindrical portion 5B.

Furthermore, 10, 10, . . . are protrusions that protrude downward in the axial direction from the lower surface of the disc 8, and each of the protrusions 1
0 are arranged concentrically and at equal angular intervals in correspondence with the small hole 4 of the inner stopper 3, and each of the protrusions 10 is longer than the axial length of the cylindrical portion 5B of the cap 5. Although the length is sufficiently short, for example, 1/3 to 1/6 of the axial dimension of the cylindrical portion 5B, the central protrusion 10A among the protrusions 10 is connected to the small hole 4A. The protrusion 10 is formed to have a larger diameter and protrude longer than the other protrusions 10 in order to fit into the protrusion 10 . Each of the protrusions 10 is formed into a tapered shape and has a rounded tip. Thus, when the cap 5 is screwed on, each protrusion 10 gradually approaches each small hole 4 of the inner plug 3 in accordance with the screwing of the male thread 1B and female thread 1, and moves into each small hole 4. Inserted,
Each small hole 4 is closed. At this time, among the projections 10, the central projection 10A fits into the small hole 4A before the other projections 10, so that the disk 8 is aligned with the inner plug 3. It's summery.

Next, the operation of the dispenser container configured as described above will be explained.

First, with the cap 5 removed, the container body 1 is inverted and shaken up and down, and the powder 2 inside the container body 1 is shaken out from each small hole 4 of the inner stopper 3. On the other hand, when the cap 5 is screwed onto the opening 1A of the container body 1, the disk 8 comes into contact with the upper slope of the annular projection 6 under its own weight, and each uneven portion 7 and 9 engage, the disc 8 can be rotated together with the cap 5 in the direction of arrow A in FIG. 5, and the male thread 1B of the female thread 5C
In response to screwing into the inner stopper 3, each protrusion 10 of the disc 8 approaches each small hole 4 of the inner stopper 3, and can be fitted into each small hole 4. At this time, since each small hole 4 is formed in a tapered shape, each projection 10 can be assisted in fitting into each small hole 4.

When the projections 10 begin to fit into the small holes 4, the rotation of the disc 8 is restricted by the small holes 4, but the uneven portions 7 and 9 are formed small (shallow). Therefore, as the cap 5 rotates in the direction of arrow A, the concavo-convex portion 9 rides on the concave-convex portion 7 of the annular protrusion 6 that is displaced downward, and the disc 8 moves on top of the concavo-convex portion 7 of the annular protrusion 6 that is displaced downward. While maintaining the fitted state in each small hole 4, only the annular projection 6, that is, the cap 5 can be rotated by only slightly moving in the axial direction. Each protrusion 10 corresponds to each small hole 4.
When the discs 8 are completely fitted together, the disk 8 is relatively pushed upward in the axial direction by the inner plug 3 via each projection 10, and the annular projection 6 is pushed downward by the screwing of the female screw 5C. Due to the displacement, the disc 8 becomes separated from the annular protrusion 6, and each uneven portion 7,
9 can be automatically released.

When the cap 5 is fastened to the opening 1C of the container body 1, the lower inclined surface 6 of the annular projection 6
A comes into contact with the lid part 3A of the inner stopper 3, and the disc 8
The upper surface of the cap 5 comes into contact with the back surface of the canopy portion 5A of the cap 5, and each small hole 4 can be maintained in a closed state by each protrusion 10, thereby ensuring sealing performance. On the other hand, in order to remove cap 5,
When rotating in the direction of arrow B in Fig. 5,
Since the slope 7B on the other side of the uneven portion 7 is sloped smaller than the slope 7A on the one side, and the uneven portion 9 of the disk 8 also corresponds to this, the cap 5 and the disk 8 can be easily rotated relative to each other. The fitting between each projection 10 and each small hole 4 can be easily released, and the cap 5 can be removed.

Thus, according to this embodiment, when the cap 5 is screwed on, the disk 8 comes into contact with the upper inclined surface of the annular protrusion 6 due to its own weight, and the uneven portions 7 and 9 engage to restrict rotation. , the disc 8 can be rotated together with the cap 5, and as the cap 5 is screwed in, each protrusion 10 of the disc 8 approaches each small hole 4 of the inner stopper 3, and the inside of each small hole 4 is moved. Further, when the cap 5 is rotated, the disc 8 is relatively pushed upward in the axial direction by the inner plug 3 via each protrusion 10, and the concavo-convex portions 7, 9 When the engagement is automatically released and the cap 5 is completely fastened to the opening 1C of the container body 1, each protrusion 10
Since each small hole 4 can be maintained in a closed state by
can be automatically and smoothly guided to each small hole 4. Incidentally, since each protrusion 10 is sufficiently shorter than the axial length of the cylindrical portion 5B of the cap 5, it does not interfere with the screwing of the cap 5. Also,
When the cap 5 is tightened, each protrusion 10 is fitted into each small hole 4 of the inner stopper 3, so when the cap 5 is removed, the powder 2 is absorbed by moisture such as surrounding water vapor. Even if powder 2 adheres to the small holes 4 and causes clogging, the powder 2 adhering to each small hole can be removed by each projection 10, and clogging can be reliably prevented.

FIG. 6 shows a second embodiment of the present invention, and the feature of this embodiment is that among the plurality of protrusions provided on the disk,
The reason is that the protrusion located in the center and one protrusion located on the periphery are made to protrude longer than each other protrusion. Note that this embodiment has the same configuration as the first embodiment. The same reference numerals will be given to the elements, and the explanation thereof will be omitted.

In the figure, numerals 11, 11, . Among them, one protrusion 1 located around the
1B is formed long like the central projection 11A.

This embodiment configured in this manner can also provide almost the same effects as the first embodiment, but in particular, in this embodiment, the protrusion 11B is formed to be as long as the protrusion 11A located at the center. Therefore, when the projection 11A is fitted into the small hole 4A when the cap 5 is screwed on, the projection 11B can also be fitted into the corresponding small hole 4 almost at the same time. Therefore, each of the projections 11 other than the projections 11A and 11B can be automatically fitted into the corresponding small hole 4 without coming into contact with the lid portion 3A of the inner stopper 3.

In each of the embodiments described above, the uneven portions 7 and 9 are provided in the circumferential direction on the upper inclined surface of the annular projection 6 and the lower surface on the outer peripheral side of the disk 8, but the uneven portions 7 and 9 are not necessarily completely formed. It is not necessary to provide them all around the circumference, but they may be provided partially at intervals in the circumferential direction. In addition, instead of the uneven portions 7 and 9, a restricting means is formed by rough finishing or other means so that the upper inclined surface of the annular protrusion 6 and the lower surface of the outer peripheral side of the disc 8 are frictionally engaged with each other. You can. Furthermore, the regulating means does not necessarily need to be provided.

Further, in each of the above embodiments, each protrusion 10A11A
However, this is not necessarily necessary, and the disk 8 can be centered with respect to the inner stopper 3 by the upper inclined surface of the annular projection 6.
Furthermore, although each projection 10, 11 and each small hole 4 are formed in a tapered shape, each projection 10, 11
Also, each small hole 4 does not necessarily have to be tapered. Moreover, the projections 10A, 11A and the small holes 4A located at the center may be formed with the same diameter as the other projections. On the other hand, in the second embodiment, the protrusion 11B may be formed to be slightly shorter than the protrusion 11A.

Furthermore, in each of the above embodiments, cosmetic powder 2 is used as an example of the powder, but powders such as salt and seasonings may be used instead, and powders of various cosmetics and foods may also be used. Of course, it can be adopted as appropriate.

[Effect of idea]

As detailed above, according to the present invention, each protrusion protruding from the disk is formed to be sufficiently short compared to the axial length of the cylindrical portion of the cap, and a canopy is provided on the inner periphery of the cylindrical portion of the cap. annular protrusions protruding radially inward at predetermined intervals in the axial direction from the cap, and holding the disc movably and rotatably in the axial direction between the annular protrusions and the canopy of the cap; Since a restricting means is provided between the outer periphery of the disk and the upper surface of the annular protrusion to restrict relative rotation of the disk to the cap, when the cap is screwed on, the restricting means will prevent the cap from rotating due to its own weight. It is possible to rotate the disc, which is regulated, together with the cap, and to bring each protrusion of the disc closer to each small hole of the inner stopper, and to fit each protrusion into each small hole, and to close the cap. When tightening, each protrusion can be automatically and smoothly guided to each small hole of the inner plug, and even if the small holes become clogged due to adhesion of powder, the powder can be removed. It is possible to reliably prevent clogging during next use.
