Thus, powder can be apply | coated to a to-be-coated part by elastically deforming a top wall part by pressing.

Special table 2008-502415 gazette

  However, in the above-described conventional application container, the powder may be excessively discharged, and it may be difficult to apply an appropriate amount of powder. In particular, the amount of coating is easily influenced by the amount of powder contained in the container body, and is excessively discharged when the powder is still sufficiently contained, such as at the start of use.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an application container that can apply an appropriate amount of powder to an application portion easily and reliably.

In order to achieve the above object, the present invention provides the following means.
(1) A coating container according to the present invention is provided with a container body in which powder is stored, and a discharge hole through which the powder is discharged is formed in the top wall part of the container body. A cylindrical cap member with a top, and the inner plug member are provided so as to be movable up and down along the container axial direction, and an application space is formed between the top wall portion and the vertical movement as described above. A bottomed cylindrical valve body that allows communication between the internal space of the container body and the application space, and blocks the communication, and the top wall portion has a dome shape that bulges outward in the container axial direction. The valve body is formed to be elastically deformable, and when the container body is inverted so that the top wall portion faces downward, the valve body moves downward with respect to the inner plug member. The communication between the internal space and the application space is blocked, and the top wall portion is elastically applied to the valve body when the container body is inverted. When being deformed, a pushed-up member is formed which is pushed up by the top wall portion and moves the valve body upward with respect to the inner plug member so as to communicate the internal space with the application space. It is characterized by being.

In the coating container according to the present invention, when the container body is inverted so that the top wall portion is directed downward in order to perform coating on the portion to be coated, the valve body moves downward with respect to the inner plug member. At this time, the valve body blocks communication between the internal space of the container body and the application space formed between the top wall portion. Thereby, the powder accommodated in the container body remains in the container body without flowing into the coating space.
Here, when the user presses the top wall portion against the application portion and elastically deforms the top wall portion so as to be depressed, the pushed-up member is pushed in. Therefore, the valve body is moved upward inward in the container axial direction with respect to the inner stopper member together with the pushed-up member, and the internal space of the container body and the application space are communicated.

Then, the powder staying inside the container body flows into the coating space. Therefore, these powders can be discharged through the discharge holes formed in the top wall portion, and the powder can be applied to the portion to be coated.
In particular, since only the powder that has flowed into the application space can be applied, an appropriate amount of powder can be applied easily and reliably. In other words, since the conventional one directly applies the powder contained in the container body, there is a risk of excessive application, but according to the present invention, it has flowed into the application space. Since only the powder is applied, an appropriate amount of powder can be applied.

  In addition, when application | coating is complete | finished and the top wall part is spaced apart from a to-be-coated part, since the elastic deformation of a top wall part is cancelled | released, a valve body will descend | fall with respect to an inside plug member again. As a result, the communication between the internal space of the container body and the application space is blocked, so that the powder stays inside the container body again without flowing into the application space. Therefore, even when it is applied next, the powder is not excessively discharged.

(2) The applicator container according to the present invention is the applicator container according to the present invention, wherein the inner plug member includes an outer cylinder portion that surrounds the valve element from the outside in the radial direction, and the valve element includes the outer cylinder. An inner cylindrical portion disposed with a gap on the inner side in the radial direction of the portion, the inner cylindrical portion contacting the outer cylindrical portion when the container body is inverted and closing the inlet to the gap An annular protrusion is formed that opens the inlet when the top wall portion is elastically deformed when inverted and connects the internal space and the coating space through a gap.

In the coating container according to the present invention, at the stage where the container body is turned upside down so that the top wall portion is directed downward, the annular protrusion of the inner cylinder portion is in contact with the outer cylinder portion, and the inner cylinder portion and the outer cylinder The entrance to the gap with the part is blocked. Thereby, the communication between the internal space of the container body and the application space is reliably blocked.
On the other hand, when the valve body moves upward relative to the inner plug member due to the elastic deformation of the top wall portion, the annular protrusion also moves simultaneously to open the entrance to the closed gap. Therefore, the internal space of the container body and the application space communicate with each other through this gap. As a result, the powder remaining inside the container body flows into the coating space through the gap.
As described above, the communication between the internal space of the container body and the application space and the blocking thereof can be reliably switched using the gap formed between the outer cylinder part and the inner cylinder part and the annular protrusion. . Therefore, an appropriate amount of powder can be more reliably applied.

(3) The applicator container according to the present invention is the applicator container according to the present invention described above, wherein the inner cylinder portion protrudes radially outward and slidably contacts the outer cylinder portion, A protruding member for guiding and supporting the movement is formed.

  In the application container according to the present invention, since the protruding member is slidably in contact with the outer cylinder portion and guides and supports the vertical movement of the valve body, the valve body can be smoothly moved up and down. Therefore, the communication between the internal space and the application space or the blocking thereof can be performed more reliably.

(4) The applicator container according to the present invention is the applicator container according to the present invention described above, wherein the protruding member is engaged with the outer cylinder portion when the valve body moves inward in the container axial direction. A locking portion for restricting the amount of movement of the valve body is formed.

In the application container according to the present invention, when the valve body moves upward relative to the inner plug member due to the elastic deformation of the top wall portion in the inverted state, the protruding member is locked to the locking portion formed in the outer cylinder portion. Therefore, the movement amount of the valve body can be regulated, and the valve body can be prevented from further moving upward.
In particular, when the container body is set upright so that the top wall portion faces upward when not in use or in use, the valve body tends to descend toward the inside of the container axial direction, that is, the container body side. Even in this case, since the protruding member is locked to the locking portion, the movement amount of the valve element is restricted. Therefore, there is no fear that the valve body will drop to the container body side.

(5) In the coating container according to the present invention, in the coating container according to the present invention, the inner cylinder portion is formed with an opening for allowing the powder flowing through the gap to flow into the valve body. It is characterized by being.

  In the application container according to the present invention, when the internal space of the container body and the application space communicate with each other and the powder flows through the gap between the outer cylinder part and the inner cylinder part, the powder is applied via the opening. Flow into the space. Therefore, the powder can flow more quickly into the coating space and can be discharged from the discharge hole. Therefore, the coating performance can be further improved.

(6) The applicator container according to the present invention is the applicator container of the present invention described above, wherein the powder plug attached to the inner plug member so as to cover the top wall portion and discharging the powder discharged from the discharge hole to the outside. It has a holding member that holds it so that it can pass through.

  In the coating container according to the present invention, since the holding member covers the top wall portion where the discharge hole is formed, it is difficult for the discharge hole to directly hit the portion to be coated when coating. Accordingly, it is possible to improve the tactile comfort received by the user's application portion. Further, since dust or the like hardly enters the discharge hole, the cleanliness can be increased.

  According to the application container according to the present invention, an appropriate amount of powder can be easily and surely applied to the application portion, which is very easy to use.

It is the figure which made the container main body upside down from the state shown in FIG.

Hereinafter, embodiments of a coating container according to the present invention will be described with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the application container 1 of the present embodiment includes a container body 2, an inner plug member 3, a valve body 4, a holding member 5, and an overcap 6.

  FIG. 1 is a partial semi-longitudinal sectional view of the application container 1. FIG. 2 is a partial semi-longitudinal sectional view of the application container 1 of FIG. As shown in FIGS. 1 and 2, a state in which the container body 2 is erected with the top wall portion 20 facing upward is referred to as an upright state, and conversely, the container body 2 is inverted and the top wall A state in which the portion 20 is directed downward is referred to as an inverted state. Therefore, the upward movement (downward movement) in the upright state and the upward movement (downward movement) in the inverted state are in opposite directions.

  In addition, each central axis of each component is located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, a direction orthogonal to the container axis O is a radial direction, and a direction around the container axis O is a circumferential direction. Further, the top wall 20 side of the inner plug member 3 along the container axis O direction is referred to as an upper side, and the bottom 11 side of the container body 2 is referred to as a lower side.

  As shown in FIGS. 1 and 2, the container body 2 is formed in a tube shape gradually narrowing from the mouth portion 10 provided at the upper end toward the bottom portion 11, and the powder P is accommodated therein. Yes. A hook-shaped portion 11a is formed on the bottom 11 of the container body 2, and the hook-shaped portion 11a can be used to suspend the container body 2 in an inverted state. In addition, a male screw portion 10 a into which the female screw portion 40 a of the overcap 6 is screwed is formed on the outer peripheral surface of the mouth portion 10.

  The inner plug member 3 is a top-cylindrical member attached to the mouth portion 10 of the container body 2, and as shown in FIGS. 1 to 3, a plurality of discharge holes 20a through which the powder P is discharged are formed. And the outer cylinder portion 21 that surrounds the valve body 4 from the outside in the radial direction. FIG. 3 is an enlarged cross-sectional view of the periphery of the mouth portion 10 of the container body 2 in the inverted state.

The outer cylinder portion 21 is fitted with a lower end fitted into the mouth portion 10, and a top wall portion 20 is continuously provided at the upper end. The outer cylinder portion 21 will be described in detail.
The outer cylinder part 21 is located above the first outer cylinder part 21a, the first outer cylinder part 21a fitted inside the mouth part 10 of the container body 2, and the first outer cylinder part 21a. A second outer cylinder portion 21b formed with a smaller diameter than the top wall portion 20 and having an upper end connected to the periphery of the top wall portion 20, and an upper end of the first outer cylinder portion 21a and a lower end of the second outer cylinder portion 21b. 1 flange portion 21c, an annular seal portion 21d extending radially outward from the upper end of the first outer cylinder portion 21a and overlapping the upper end surface of the mouth portion 10 of the container body 2, and the second outer cylinder portion 21b A peripheral wall portion 21e that surrounds from the outside in the radial direction and has a smaller diameter than the first outer cylinder portion 21a, and a second flange portion 21f that connects the lower end of the peripheral wall portion 21e and the lower end of the second outer cylinder portion 21b, , Is composed of.

The first outer cylinder portion 21 a is fitted inside the mouth portion 10 of the container body 2 as described above, and seals the powder P inside the container body 2. Further, since the seal portion 21d overlaps the upper end surface of the mouth portion 10 without a gap, the structure is such that dust, moisture, and the like do not easily enter the inside of the container body 2 from the outside. Accordingly, the quality of the powder P accommodated in the container body 2 is maintained for a long time without deterioration.
The second outer cylinder portion 21b is located above the first outer cylinder portion 21a, that is, above the mouth portion 10, and the top wall portion 20 is separated from the mouth portion 10 to be coated X (FIG. 5). The top wall 20 is easily pressed against the reference).

  The first flange portion 21c is formed so as to gradually go upward as it goes from the radially outer side to the inner side. As a result, when the container body 2 is inverted so that the mouth portion 10 faces downward, the powder P naturally moves on the first flange portion 21c and easily moves toward the second outer cylinder portion 21b. (See FIG. 3). That is, it is designed so that the powder P can be easily introduced into the gap S between the second outer cylinder portion 21b and the inner cylinder portion 30 of the valve body 4 described later.

  The top wall portion 20 is formed in a dome shape bulging upward, which is the outer side in the container axis O direction, and is formed to be elastically deformable. Therefore, when the top wall portion 20 is pressed against the application portion X via the holding member 5, the top wall portion 20 can be deformed so as to be recessed. The top wall portion 20 is formed with a plurality of discharge holes 20a over the entire surface.

The valve body 4 is a bottomed cylindrical member attached to the inner side of the inner plug member 3 in the radial direction along the container axis O direction so as to move up and down, and the application space E2 is defined between the valve body 4 and the top wall portion 20. In addition to the formation, the inner space E1 and the coating space E2 of the container body 2 are communicated with each other and moved to block the communication.
Specifically, as shown in FIG. 3, when the container body 2 is inverted so that the top wall portion 20 faces downward, the valve body 4 moves downward (the top wall portion 20 side, outside in the container axis O direction). ) To block the communication between the internal space E1 and the coating space E2, and when the top wall portion 20 is elastically deformed at the time of the inversion, the valve body 4 moves upward (the bottom 11 side of the container body 2, the container The inner space E1 and the coating space E2 are communicated by moving inward in the direction of the axis O.

The valve body 4 will be described in more detail with reference to FIGS. FIG. 4 is an external perspective view of the valve body 4.
The valve body 4 includes an inner cylinder part 30 disposed with a gap S on the inner side in the radial direction of the second outer cylinder part 21b, a bottom wall part 31 connected to the lower end of the inner cylinder part 30, A rod portion (a member to be pushed up) 32 that protrudes from the center of the bottom wall portion 31 along the container axis O toward the upper end of the inner cylinder portion 30.

The bottom wall portion 31 is formed in a tapered shape that inclines toward the bottom portion 11 of the container body 2 as it goes radially inward, and is angled with respect to the container axis O. Accordingly, when the container body 2 is inverted so that the mouth portion 10 faces downward (see FIG. 3), the powder P naturally moves on the bottom wall portion 31 and tends to face the inner cylinder portion 30. Yes. That is, the powder P can be easily guided into the gap S between the second outer cylinder portion 21 b and the inner cylinder portion 30.
Moreover, the rod part 32 is formed in the length exceeding the upper end surface of the inner cylinder part 30, and when the valve body 4 moves to the top wall part 20 side, an upper end is located near the top wall part 20. Designed to. When the top wall portion 20 is elastically deformed, the rod portion 32 is pushed up by the top wall portion 20 and plays a role of moving the valve body 4 upward in the container axis O direction.

An annular protrusion 33 protruding outward in the radial direction is formed at a connection portion between the inner cylinder portion 30 and the bottom wall portion 31. When the container body 2 is inverted so that the mouth portion 10 faces downward (see FIG. 3), the annular protrusion 33 contacts the outer cylinder portion 21, that is, the first flange portion 21c of the inner plug member 3. In contact with the connecting portion between the second outer cylinder portion 21b and the entrance to the gap S.
That is, when the container body 2 is inverted, the valve body 4 is moved downward (outside in the container axis O direction) by its own weight, that is, toward the top wall 20 side, and as a result, the annular protrusion 33 is moved to the first flange portion 21c. And a contact portion between the second outer cylinder portion 21b. Thereby, the entrance to the gap S is blocked, and the communication between the internal space E1 and the coating space E2 is blocked. Therefore, the powder P remains in the container body 2.

  On the other hand, when the top wall portion 20 is elastically deformed at the time of inversion, the valve body 4 is moved upward in the container axis O direction by the rod portion 32 as described above, so that the annular protrusion portion 33 is formed. It is spaced apart from the connecting portion between the first flange portion 21c and the second outer cylinder portion 21b, and opens the entrance to the gap S. Thereby, the internal space E1 and the application space E2 can be communicated with each other through the gap S, and the powder P can be caused to flow into the application space E2 through the gap S.

  In addition, a protruding member 34 is formed on the outer surface of the inner cylinder portion 30 so as to protrude radially outward and slidably contact the inner surface of the second outer cylinder portion 21b to guide and support the vertical movement of the valve body 4. ing. In the present embodiment, four are formed every 90 degrees in the circumferential direction around the container axis O. However, the number of the protrusion members 34 is not limited to this case. The valve body 4 moves smoothly up and down by these protruding members 34.

In addition, when the valve body 4 moves toward the bottom 11 side (inner side in the container axis O direction) of the container body 2 when the valve body 4 is inverted, the protruding member 34 is locked to the inner surface of the second outer cylinder portion 21b. A locking portion 25 that restricts the amount of movement of the valve body 4 is formed.
Further, the inner cylinder portion 30 of the valve body 4 has a slit (opening) that allows the powder P that has flowed through the gap S between the second outer cylinder portion 21 b and the inner cylinder portion 30 to flow into the valve body 4. Part) 35 is formed. The slits 35 are linearly formed along the container axis O from the upper end of the inner cylinder part 30 to the annular projection part 33, and are formed at intervals of 90 degrees in the circumferential direction around the container axis O. Yes. At this time, the four slits 35 are formed so as to be positioned between the four protruding members 34. However, the slits 35 are not limited to this position and number.

  As shown in FIGS. 1 to 3, the holding member 5 is attached to the inner plug member 3 so as to cover the top wall portion 20 described above, and can pass the powder P discharged from the discharge hole 20 a to the outside. It is a member hold | maintained. Specifically, it is an elastically deformable porous material, for example, a sponge body. Then, the holding member 5 is mounted so as to be hooked on the peripheral wall portion 21e and the second flange portion 21f of the inner plug member 3 while covering the entire top wall portion 20.

The overcap 6 includes a peripheral wall portion 40 that surrounds the mouth portion 10 of the container body 2 from the outside in the radial direction, and a top wall portion 41 that covers the holding member 5 and the top wall portion 20.
On the inner surface of the peripheral wall portion 40, a female screw portion 40a that is screwed into the male screw portion 10a of the mouth portion 10 is formed from the substantially central portion to the lower end. Thereby, the overcap 6 can be attached to the mouth portion 10 of the container body 2. The top wall portion 41 is formed to swell in a dome shape corresponding to the bulge of the top wall portion 20, and can completely cover the holding member 5 and the top wall portion 20.
When the overcap 6 is attached, the peripheral edge of the top wall portion 41 comes into contact with the seal portion 21 d of the inner plug member 3. Thereby, the top wall 41 is designed so as not to contact the holding member 5.

  The peripheral wall portion 40 is formed so as to be curved radially outward from the substantially central portion to the upper end, and is formed so that the upper end is located above the apex of the top wall portion 41. . Thereby, the surrounding wall part 40 can be mounted on a desk etc. in the inverted state which turned the container body 2 upside down, and it can be stably stored in this state.

Next, the case where the powder P is applied to the portion X (see FIG. 5) using the application container 1 configured as described above will be described.
First, the application container 1 of the present embodiment is stored while stably maintaining the inverted state with the top wall portion 20 facing downward when not in use. That is, the peripheral wall portion 40 of the overcap 6 can be placed on a desk or the like, or can be hung using the hook-shaped portion 11a of the container body 2, and can be stored in an inverted state.

In this inverted state, as shown in FIG. 3, the valve body 4 naturally moves downward toward the top wall portion 20, so that the annular protrusion 33 is connected to the first flange portion 21 c and the second flange portion 21 c of the inner plug member 3. It is in contact with the connecting portion with the outer cylinder portion 21b. Therefore, the entrance to the gap S between the second outer cylinder portion 21b and the inner cylinder portion 30 is blocked, and the communication between the internal space E1 of the container body 2 and the application space E2 is blocked.
Therefore, the powder P accommodated in the container body 2 remains in the container body 2 without flowing into the application space E2.

Next, when applying, after rotating the overcap 6 around the container axis O and removing it from the mouth 10 of the container body 2, as shown in FIG. 5, the top wall is interposed via the holding member 5. The portion 20 is pressed against the portion X to be coated, and is elastically deformed so that the top wall portion 20 is depressed. Then, the rod part 32 is pushed in by the elastic deformation of the top wall part 20. As a result, the valve body 4 is moved upward together with the rod portion 32 toward the bottom 11 side of the container body 2 which is the inner side in the container axis O direction.
Then, the annular protrusion 33 of the valve body 4 is separated from the inner plug member 3 by this upward movement, so that the entrance to the gap S between the second outer cylinder part 21b and the inner cylinder part 30 that has been blocked up to this point. Can be released. Therefore, the internal space E1 of the container body 2 and the coating space E2 can be communicated through the gap S.

  When the entrance to the gap S between the second outer cylinder portion 21b and the inner cylinder portion 30 is opened, the powder P remaining inside the container body 2 flows into the application space E2 through the gap S. Therefore, the powder P that has flowed into the application space E2 can be discharged through the discharge hole 20a formed in the top wall portion 20, and is applied to the application portion X after passing through the holding member 5. be able to.

  In particular, since only the amount of the powder P that has flowed into the coating space E2 can be applied, the appropriate amount of the powder P can be easily applied. That is, since the conventional one directly applies the powder P accommodated in the container body, there is a fear that it is excessively applied. However, according to the application container 1 of the present embodiment, only the powder P that has flowed into the application space E2 is applied, so that an appropriate amount of the powder P can be applied.

  Part of the powder P that has flowed into the gap S between the second outer cylinder portion 21 b and the inner cylinder portion 30 flows into the coating space E <b> 2 through the slit 35. Therefore, the powder P can flow more quickly into the coating space E2 and can be discharged from the discharge hole 20a. Therefore, the coating performance can be further improved.

  Further, when the powder P is applied, the holding member 5 covers the top wall portion 20 in which the discharge holes 20a are formed. Therefore, the tactile comfort received by the user's coated part X can be improved. Further, since dust or the like hardly enters the discharge hole 20a, the cleanliness can be increased.

  Further, as described above, when the valve body 4 moves upward due to elastic deformation of the top wall portion 20, the internal space E1 of the container body 2 and the application space E2 communicate with each other, and the powder P flows into the application space E2. At this time, the four protruding members 34 are locked to the locking portions 25 formed on the inner surface of the second outer cylinder portion 21b. Therefore, the movement amount of the valve body 4 can be regulated, and the valve body 4 can be prevented from further moving upward. In this respect as well, an appropriate amount of the powder P can be applied.

  Next, when the application is completed and the holding member 5 and the top wall portion 20 are separated from the portion to be coated X, the elastic deformation of the top wall portion 20 is released, so that the valve body 4 is again on the side of the top wall portion 20. Move down toward. Then, as shown in FIG. 3, the annular projecting portion 33 comes into contact with the inner plug member 3 again and closes the entrance to the gap S between the second outer cylinder portion 21 b and the inner cylinder portion 30. As a result, the communication between the internal space E1 and the coating space E2 of the container body 2 is blocked, so that the powder P remains in the container body 2 without flowing into the coating space E2. Therefore, even if it is a case where it apply | coats next, the powder P is not discharged | emitted excessively.

  Further, when the container body 2 is set upright so that the top wall portion 20 faces upward when not in use or in use, the valve body 4 is positioned on the bottom 11 side of the container body 2 as shown in FIG. Even in this case, since the four projecting members 34 are locked to the locking portions 25, the amount of movement of the valve body 4 is restricted. Therefore, there is no fear that the valve body 4 will fall to the container body 2 side.

  Further, regardless of whether the valve body 4 moves up or down, the four projecting members 34 slidably contact the inner surface of the second outer cylinder portion 21b to guide the vertical movement of the valve body 4. Since it supports, the valve body 4 can be smoothly moved up and down along the container axis O. Therefore, the communication between the internal space E1 of the container body 2 and the coating space E2 can be reliably performed.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, when the valve body 4 moves up and down, the inlet of the gap S between the second outer cylinder portion 21b and the inner cylinder portion 30 is opened or blocked by the annular protrusion 33, and as a result, the container body However, the present invention is not limited to such a configuration. Any configuration may be employed as long as the communication between the internal space E1 and the application space E2 and the blocking of the communication can be reliably switched with at least the vertical movement of the valve body 4.

Moreover, in the said embodiment, although the four protrusion members 34 were formed in the outer surface of the inner cylinder part 30, you may form the protrusion member 34 cyclically | annularly over the perimeter of the outer surface of the inner cylinder part 30. FIG. In this case, the powder P may be flowed into the coating space E2 through the slit 35.
In addition, the slit 35 is formed in a vertically long shape along the container axis O, but may be formed in a horizontally long shape in the circumferential direction. Furthermore, it may be a simple opening.

  Moreover, in the said embodiment, although it was set as the structure which covered the top wall part 20 with the holding member 5, the holding member 5 is not essential and does not need to be provided. However, since the holding member 5 is provided, dust or the like can be prevented from entering the discharge hole 20a, or the discharge hole 20a can be prevented from coming into direct contact with the portion to be coated X. It is preferable to configure as described above.
