  By the way, in such a conventional container, the clearance gap between the opening of the container which extracts the contents (the swing outlet in Patent Document 1) and the plug body provided with the recess (the first and second plug parts in Patent Document 1) If the value is too large, there is a risk that the content more than the expected amount will be discharged, or there will be a possibility that the outside air will always enter from this gap and the quality of the contents will deteriorate, so it is preferable to make the gap as small as possible. However, when the operation button (push part in Patent Document 1) is pushed in from an oblique direction, the gap between the plug body and the opening is small, and the plug body comes into strong contact with the side wall of the opening. There was a problem that a strong force was required.

  In addition, depending on the particle size and type of the content, the content cannot be smoothly transferred into the recess, the amount of the content to be filled in the recess is insufficient, or the filled content is removed from the recess. In some cases, all of the contents were not discharged, and there was a risk that the extracted amount of the contents would be smaller than the expected amount. For this reason, there is still room for improvement in terms of the operability related to the extraction of the contents and the point of extracting the contents in an accurate amount.

  An object of the present invention is to solve such a conventional problem, and an object of the present invention is to obtain good operability even if the gap between the opening of the container and the stopper is reduced. A new quantitative extraction container is proposed which can reliably extract the contents of the expected amount only once.

The present invention includes a container body having a cylindrical body for storing powder inside thereof, a top wall having a through-hole formed at the upper end of the body, and a plug body having a recess on the side. A rod provided at a lower end and connected to an operation button disposed above the top wall through the through hole, and provided inside the fuselage, closes the fuselage by abutting against the plug, An elastic wall that closes the recess when the operation button is pressed and discharges only the powder in the recess when the operation button is further pressed.
At the lower end of the container body, a bottom body is provided that has an extraction port for powder discharged from the recess and a guide pin that stands up toward the rod.
A quantitative extraction container, wherein the rod is provided with a deep hole for accommodating the guide pin inside.

  It is preferable to provide a spiral groove on either the outer peripheral surface of the guide pin or the inner peripheral surface of the deep hole, and to provide a protruding portion linked to the spiral groove on the other.

  The elastic wall includes an annular base that is held on the inner peripheral surface of the body, and an annular tongue that connects one end of the elastic wall to the base and makes the other end abut against the plug over the entire circumference. It is preferable to consist of.

  It is preferable that an elastic body for urging the rod upward is provided between the bottom body and the plug body.

  The quantitative extraction container according to the present invention closes the inside of the body by contacting the stopper and closes the inside of the body, and closes the recess when the operation button is pushed, and further pushes the operation button to remove the powder in the inside of the body. An elastic wall that discharges only the body is provided, a bottom body that has a powder extraction port and a guide pin that stands up toward the rod is provided, and a deep hole that accommodates the guide pin is provided in the rod. . That is, since the portion that contacts the plug is an elastic wall and only a light force acts on it, even if it makes contact with no gap, the pressing force of the operation button is not greatly affected. In addition, as a result of the rod being guided and pushed down by the guide pin, the plug body can be moved straight regardless of how the operation button is pressed, so that the plug body does not press strongly against the elastic wall, and the operation is good. Sex can be obtained. Furthermore, even if the plug body and elastic wall are worn slightly due to rubbing due to continuous use, the elastic wall follows and keeps contact with no gap, so the initial performance is maintained over a long period of time. can do.

  When a spiral groove is provided on one of the outer peripheral surface of the guide pin or the inner peripheral surface of the deep hole, and a projection portion linked to the spiral groove is provided on the other side, the rod is moved along the guide pin by pushing the operation button. It can be rotated around the guide pin while pushing down, so that the powder can be introduced into the recess and discharged from the recess more smoothly. This makes it difficult for defective discharge to occur. In addition, since the centrifugal force acts on the powder filled in the recess, the powder can be discharged more reliably. Therefore, it is possible to extract a predetermined amount of powder more accurately and more stably.

  An annular base that holds the elastic wall on the inner peripheral surface of the body, and an annular tongue that connects one end of the elastic wall to the base and makes the other end contact the entire circumference of the plug By configuring, the annular tongue piece can be uniformly brought into contact with the plug body in the circumferential direction, so that the contents can be effectively prevented from overflowing from between the annular tongue piece and the plug body. it can.

  When an elastic body that urges the rod upward is provided between the bottom body and the plug body, the rod can be returned to the initial position when the hand is released from the pressed operation button. The operability according to can be improved.

Here, as shown in FIG. 1, the annular tongue piece 52 abuts the lower end side plug portion 32 b and closes the storage space M at an initial position before the rod 30 is pushed. At this time, the annular tongue piece 52 is not in contact with the upper end side plug portion 32a, and the recess 33 is open. Further, the upper surface of the base 51 is an inclined surface 53 that is inclined downward from the radially outer side toward the inner side.

  The bottom body 60 includes an annular holding portion 61 that is held on the inner peripheral surface of the body 10, and a bottom wall 62 that is integrally connected to the annular holding portion 61 and that houses the rod 30 and the elastic wall 50 inside to close the body 10. It has. A guide pin 63 that stands up toward the deep hole 34 of the rod 30 is provided at the center of the bottom wall 62, and a step portion 64 having a larger diameter than the guide pin 63 is provided at the base of the guide pin 63. ing. Further, an extraction port 65 penetrating the front and back of the bottom wall 62 is provided on the radially outer side of the guide pin 63. Here, the bottom wall 62 is formed so as to be inclined downward from the radially outer side toward the extraction port 65. A downward annular wall 66 is provided on the lower surface of the bottom wall 62.

  The elastic body 70 is a coil spring in this embodiment, and a lower portion thereof is inserted into the stepped portion 64 of the guide pin 63, and an upper portion thereof is held in the concave portion 35 of the rod 30. The elastic body 70 may be provided between the lid body 20 and the operation button 40.

  The cap 80 includes a disc-shaped cap main body 81, and has a columnar bulging portion 82 at the center thereof and an annular portion 83 with a flange at the edge thereof. Thus, the cap 80 is held by the container body 1 by fitting the bulging portion 82 to the downward annular wall 66 of the bottom body 60 and fitting the annular portion 83 to the large diameter portion 11 of the body 10.

  In the quantitative extraction container configured as described above, the powder as the contents is accumulated on the plug 32 side with the operation button 40 facing upward as shown in FIG. The whole can be filled with powder. Further, the upper surface of the base 51 is an inclined surface 53 that is inclined downward toward the recess 33, and the powder that is the content flows into the recess 33 along the inclined surface 53. Filling of powder is performed more reliably. And since the annular tongue piece 52 is in contact with the lower end side plug body portion 32b over the entire circumference, the powder does not overflow from the space between them.

  In extracting the powder, the cap 80 is removed, and then the operation button 40 is pressed to move the rod 30 downward. When the rod 30 is moved to the position shown in FIG. 2, the recess 33 is closed by the annular tongue piece 52, and a predetermined amount of powder is filled in the recess 33. The recess 33 is closed when the annular tongue piece 52 is in contact with both the upper end plug portion 32a and the lower end plug portion 32b and the recess 33 is completely closed. This includes the case where the tongue piece 52 is close to the upper end side plug part 32a and the lower end side plug part 32b with a slight gap therebetween. Normally, the operation button 40 is continuously pressed until the rod 30 has been pushed in, and the rod 30 continues to move. Therefore, the annular tongue piece 52, the upper end plug portion 32a, and the lower end plug body. Even if there is a slight gap between the portion 32b, the contents do not enter and exit the recess 33, and the recess 33 can be regarded as being substantially closed.

  When the pressing on the operation button 40 is continued, as shown in FIG. 3, the lower surface of the concave portion 35 provided on the rod 30 comes into contact with the upper surface of the stepped portion 64 provided at the root of the guide pin 63, Push-in ends (push-in end position). At this time, since the annular tongue 52 abuts only on the upper end side plug portion 32a and the recess 33 is in an open state, the powder in the storage space M does not overflow and the powder in the recess 33 does not overflow. Only falls to the bottom body 60. Then, the fallen fixed amount of powder is extracted to the outside through the extraction port 65. The bottom wall 62 is formed so as to incline downward from the radially outer side toward the extraction port 65, so that the powder falling from the recess 33 is smoothly extracted along the inclined surface of the bottom wall 62. Extracted from mouth 65. The rod 30 is moved downward while being guided by the deep hole 34 and the guide pin 63. As a result, the plug 32 can be moved straight regardless of how the operation button 40 is pressed. Good operability can be obtained without strongly pressing against the tongue piece 52.

  Moreover, since the rod-shaped part 42 of the operation button 40 can also be guided by the inner annular wall 23 provided on the lid 20, even better operability can be obtained.

  Then, when the hand is released from the operation button 40 after the powder is extracted, the rod 30 can be moved to the initial position shown in FIG. 1 by the restoring force of the elastic body 70, so that the rod 30 is returned to the original position. The operation to return is unnecessary. The elastic body 70 may be integrally connected to the plug body 32 or the bottom body 60. For example, by providing a bellows portion toward the bottom body 60 in the lower end side plug body portion 32b, the number of parts can be reduced. it can.

  Further, if at least the body 10 is formed of a transparent material, the remaining amount of the contents can be easily visually confirmed, and the contents in the storage space M can be surely filled into the recesses 33. It is particularly preferable because it can be confirmed visually that all the components have been extracted. Furthermore, by giving decoration (for example, coloring) to the rod 30, it becomes possible to produce a special eye-catching effect and can be differentiated from the conventional quantitative extraction container.

  Next, a second embodiment of the quantitative extraction container according to the present invention will be described. In addition, about what fulfill | performs the same function as what was demonstrated in 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 4 is a cross-sectional view of the second embodiment of the quantitative extraction container according to the present invention in a side view in an initial position before pushing the rod, and FIG. 5 shows the rod with the cap removed from the state shown in FIG. FIG. 6 is a cross-sectional view at the rod pushing end position showing a state in which the powder in the recess is discharged, and FIG. 6 shows that the elastic body is restored from the state shown in FIG. It is sectional drawing which shows the state which returned to.

  In the second embodiment, a spiral groove 34 a is provided on the inner peripheral surface of the deep hole 34 described above, and a protrusion 63 a linked to the spiral groove 34 a is provided on the outer peripheral surface of the guide pin 63. That is, in the first embodiment, the rod 30 is linearly displaced along the guide pin 63. In the second embodiment, the rod 30 is further moved around the lower end annular wall 42a of the operation button 40 and the guide pin 63 during the linear displacement. The rod 30 can be rotated. This allows the powder to move into and out of the recess more smoothly, and in combination with the centrifugal force acting on the powder in the recess, removes the powder in the recess. It can be discharged more reliably. Note that a spiral groove may be provided on the outer peripheral surface of the guide pin 63 and a protrusion may be provided on the inner peripheral surface of the deep hole 34.

  Here, when a coil spring is used as the elastic body 70, as shown in FIG. 7A, the rotation direction of the rod 30 when pressing the operation button 40 (left when viewed from the top to the bottom of the container) It is preferable that the winding direction of the coil spring (winding direction starting from the upper end 70a of the coil spring) be reversed (clockwise when viewed from above the container downward). When the operating button 40 is pressed and the rod 30 is pushed in, the coil spring and the lower surface of the recess 35 come into strong contact with each other. However, by using the coil spring in the winding direction, the lower surface of the recess 35 is lowered by the upper end 70a. There is a low risk of being scraped, and it is possible to suppress a problem that shavings are mixed into the contents. As shown in FIG. 7B, when the rod 30 is returned, the rotation direction of the rod 30 and the winding direction of the coil spring coincide with each other. However, since the rod 30 is displaced away from the coil spring, the occurrence of shaving is generated. Is effectively prevented.

  According to the present invention, even if the gap between the opening of the container and the stopper is made small, the pushing operation when extracting the powder becomes good, and the amount of the contents as expected is surely delivered only once. A new quantitative extractor that can be extracted can be provided.
