  By the way, such a conventional container has an opening (a neck part of the bag in Patent Document 1 and an outlet in Patent Document 2) for extracting contents, and a stopper (in Patent Document 1) provided with a recess. If the gap between the metering cylinder and the second stopper portion in Patent Document 2) is too large, the contents may exceed the expected amount, or the outside air may constantly enter from this gap. There was a concern that the quality of the product would deteriorate. On the other hand, if the gap is too narrow, strong contact occurs between them, and there is a problem that operability during extraction is deteriorated. Moreover, in order to make it an appropriate clearance, since it is necessary to strictly manage both dimensions, there is also a problem in terms of container productivity. Furthermore, if the container is continuously used, the gap between them gradually expands due to abrasion due to rubbing, etc., and the initial performance cannot be exhibited, and there is still room for improvement in these respects. It was left.

  An object of the present invention is to solve such a conventional problem, and the object of the present invention is to extract contents in an expected amount with good operability. A new quantitative extraction container that can maintain the initial performance over a long period of time is proposed.

Here, the stopper 50d is set to a length that makes contact with the other end 20f at the initial position of the rod 20 or a slight gap when the cap 50 is attached to the tip cover 13. .

  In the quantitative extraction container configured as described above, since the powder as the contents is accumulated on the plug body 20b side with the operation unit 30 facing upward as shown in the figure, the recess 20c The whole can be filled with powder. In addition, since the base 11d of the elastic wall 11c is an inclined surface that is inclined downward toward the recess 20c, the filling of the powder into the recess 20c is more reliably performed. And since the elastic wall 11c which is an annular tongue piece is contact | abutting over the other end side plug part 20e over the perimeter, a powder does not overflow from these mutual.

  In extracting the powder, after removing the cap 50, the operating portion 30 is pressed to displace the rod 20 to the other end side, so that the elastic wall 11c is plugged on the one end side as shown in FIG. The recess 20c is closed in contact with both the body portion 20d and the plug portion 20e on the other end side, and a fixed amount of powder is filled in the recess 20c. Further, the pressure on the operation unit 30 is further continued, and as shown in FIG. 3, the elastic wall 11c is displaced so as to come into contact with only the one end side plug part 20d, so that only the powder in the recess 20c is at the tip. It is poured out from the front end opening 13 b of the cover 13.

  When the pressure on the operation unit 30 is released, the rod 20 is displaced to the initial position shown in FIG. 1 by the urging force of the spring member 41 and the bellows member 42. The body can be extracted continuously. Since the elastic wall 11c, which is an annular tongue, uniformly contacts at least one of the one end side plug body portion 20d and the other end side plug body portion 20e during the displacement of the rod 20, the rod 20 It is possible to remove the risk of the tilting being pushed.

  After use, by attaching the cap 50 to the tip cover 13, the tip opening 13 b of the tip cover 13 is closed by the closing plate 50 a of the cap 50, so that the frequency of outside air entering the body 11 is increased. It can be surely suppressed. Further, at the initial position of the rod 20, the stopper 50d of the cap 50 is set to a length that makes contact with the other end 20f of the rod 20 or slightly opens a gap. Can be reliably prevented.

  When using the bellows member 42, the bellows member 42 prevents the powder from entering between the opening 12f of the lid 12 and the rod main body 20a, so that the operability of the rod 20 is hindered by the powder. Disappears.

  Further, as shown in FIG. 4, the quantitative extraction container according to the present invention can be configured by only the bellows member 42 without using the spring member 41, and although not shown, the bellows member 42 is not used. It can also be configured with only the spring member 41.

  According to the present invention, the pushing operation when extracting the powder becomes good, the contents can be extracted in the expected amount, and the initial performance can be maintained over a long period of time even when used repeatedly. It is possible to provide a new quantitative extractor that can be maintained.
