The valve member 40 is supported by a valve body support member 50 that is fitted and held in the cap main body portion 30. The valve member 40 includes a substantially cylindrical base portion 41 and a slit valve 42 extending inward from the upper end of the base portion 41 . The valve member 40 is configured so that when the body portion 12 is squeezed, pressure is applied from the housing space S side, and the slit valve 42 opens. Only while the slit valve 42 is open, the contents in the storage space S can move toward the discharge port 34. The valve member 40 is made of a soft material such as rubber or elastomer.

The slit valve 42 is arranged inside the cylindrical portion 33 near the root of the cylindrical portion 33 . Further, the slit valve 42 has a slit 42a formed in the center thereof, which has a cross shape in plan view. Further, the slit valve 42 of this example has a dome shape that bulges from the discharge port 34 side toward the accommodation space S side.

Note that the lid body 60 is not an essential component. Further, the lid body 60 is not limited to a configuration in which it is integrally connected to the cap main body portion 30, but may be configured to be formed as a separate member and detachably attached by screw connection or the like.

Below, a method of using the powder discharge container 1 of this embodiment will be explained. When discharging the contents from the powder discharging container 1, first, as shown in FIG. Get into a headstand position.

Note that the inverted posture only requires that the mouth portion 11 side is located lower than the bottom portion, and the axis O may extend in the vertical direction, or may be inclined with respect to the vertical direction as shown in FIG. You can leave it there. When the container body 10 is placed in an inverted position, the contents move toward the mouth 11 within the storage space S. At this time, the pressure applied to the contents flowing into the slit valve 42 side is reduced by the lower wall 55, so that the contents do not pass through the slit valve 42 and spill out from the discharge port 34 before squeezing the body 12. This can be suppressed more reliably, and it is also possible to prevent the contents from being pressurized and solidifying in front of the slit valve 42 (on the housing space S side).

When the body 12 of the container body 10 in the inverted position is squeezed, the accommodation space S is pressurized and the slit 42a of the slit valve 42 is opened. At this time, the contents in the storage space S pass through the space 56 (the intermittent portion of the connecting piece 54) provided between the lower wall 55 and the flange portion 52, and the slit valve 42, and further pass through the contents passage R. and is discharged from the discharge port 34.

Here, the contents that have passed through the slit valve 42 with force collide with the inner wall surface (the inner circumferential surface of the cylindrical part 33) in the process of passing through the content passage R, and as a result, the contents also collide with each other. Therefore, the momentum of movement toward the discharge port 34 is reduced. As described above, according to the powder discharge container 1 of the present embodiment, by reducing the momentum of the contents that have passed through the slit valve 42 in the content passage R, the momentum of the contents discharged from the discharge port 34 can be reduced. This makes it possible to discharge the powdered contents with appropriate force in the target direction. As a result, scattering of the discharged contents to the surroundings can be suppressed.

When the squeeze of the body part 12 is released, the body part 12 returns to its original shape due to the restoring force, and the negative pressure generated at this time introduces outside air into the accommodation space S from the discharge port 34.

In addition, in the powder discharge container 1 of this embodiment, by keeping the strength constant when squeezing the body 12, a substantially constant amount of contents can be discharged every time the squeeze operation is performed. I can do it. Furthermore, by adjusting the strength with which the trunk 12 is squeezed, it is also possible to adjust the amount of content to be discharged. That is, when the body 12 is strongly squeezed, the container body 10 undergoes a large volume reduction deformation, and a relatively large amount of the contents is discharged.On the other hand, when the body 12 is weakly squeezed, the container body 10 The amount of volume reduction deformation is reduced, and only a relatively small amount of the contents is discharged.

In the powder discharge container 1 of this embodiment, an inwardly inclined portion 33a is provided in the distal end region of the cylindrical portion 33. With this configuration, the contents moving in the contents passage R collide with the inner surface of the inwardly inclined portion 33a, and as a result, the contents further collide with each other, so that the momentum of the contents is more effectively reduced. In addition, it is possible to improve the accuracy of the discharge direction of the contents. Furthermore, even if the length L of the cylindrical part 33 is made smaller, compared to the case where the inwardly inclined part 33a is not provided (the diameter of the cylindrical part 33 is constant up to the tip), the content can be sufficiently absorbed. Since the force reduction effect can be obtained, the height of the discharge cap 2 and the height of the powder discharge container 1 as a whole can be suppressed. Note that the inwardly inclined portion 33a may be located at the tip side of the cylindrical portion 33 instead of the root side (top wall 32 side); More preferably, it is provided in the section.

In the powder discharge container 1 of this embodiment, the valve member 40 is held inside the cap body portion 30 by the valve body support member 50. With such a configuration, the valve member 40 and the valve body support member 50 are integrated with the cap body portion 30, so that attachment and detachment operations to and from the container body 10 are facilitated. That is, by simply attaching the cap body portion 30 to the container body 10 containing the contents, the valve member 40 and the valve body support member 50 can be easily attached at the same time, and removal from the container body 10 can also be done all at once. be able to.

In the powder discharge container 1 of this embodiment, it is preferable that the length L of the content passage R shown in FIG. 1 is 5 mm or more. It can be reduced more appropriately. Moreover, it is preferable that the length L of the content passage R is 70 mm or less, and according to this, by suppressing the size of the cylindrical part 33 to an appropriate range, the entire discharge cap 2 or the powder discharge container 1 can be It is possible to maintain good transportation efficiency and storage efficiency by preventing the size from becoming too large. Note that the length L of the content passage R is the length in the axial direction of the cylindrical portion 33 from the center of the slit valve 42 to the discharge port 34.

Note that the type of content accommodated in the accommodation space S is not particularly limited as long as it is a powder, but for example, if the particle size of the content is 100 μm or less, the content that has passed through the slit valve Powder-like contents were easily discharged with force and scattered to the outside of the target object, but according to the powder discharge container 1 of this embodiment, such problems do not occur and the powder can be easily scattered in the target direction. Powder-like contents can be discharged with appropriate force. In addition, even when the bulk density of the contents was 1.0 g/ml or less, the powdered contents that passed through the slit valve were easily discharged with force and scattered to the outside of the target object. According to the powder discharge container 1 of the embodiment, the powder-like contents can be discharged with appropriate force in the target direction without such a problem occurring. Therefore, the present invention is particularly effective when the particle size of the contents is 100 μm or less, or when the bulk density of the contents is 1.0 g/ml or less.

It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof. For example, in the previous embodiment, the peripheral wall 31 was screwed to the mouth 11 of the container body 10, but the peripheral wall 31 may be fitted and held to the mouth 11.
