It may be partially curved or bent. Further, in this example, the entire cylindrical portion 33 is formed in a cylindrical shape having a circular cross section (transverse cross section) perpendicular to the axis O, but is not limited thereto, and the cross section is elliptical, or A polygonal cylindrical shape may be used. Moreover, although the cylindrical part 33 of this example is arrange | positioned in the center of the top wall 32, it is not restricted to this.

  The valve member 40 is disposed on the inner side of the cap main body 30 and is provided in a flow path of contents from the accommodation space S toward the discharge port 34. The valve member 40 is supported by a valve body support member 50 that is fitted and held in the cap main body 30. The valve member 40 includes a substantially cylindrical base portion 41 and a slit valve 42 extending inward from the upper end portion of the base portion 41. The valve member 40 is configured such that when the body portion 12 is squeezed, it is pressurized from the accommodation space S side and the slit valve 42 is opened. Only when the slit valve 42 is open, the contents in the accommodation space S can move toward the discharge port 34. The valve member 40 is formed of a soft material such as rubber or elastomer.

  The slit valve 42 is disposed inside the tubular portion 33 in the vicinity of the root of the tubular portion 33. Further, the slit valve 42 is formed with a slit 42a having a cross shape in a plan view at the center. 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. The slit valve 42 is not limited to a dome shape, and may be a flat shape, or a dome shape that bulges from the accommodation space S side toward the discharge port 34 side, contrary to the illustrated example. The slit 42a is not limited to two slits forming a cross shape, and may be one or three or more.

  The base portion 41 is sandwiched between the step portion 35 formed on the inner surface of the connecting portion of the tubular portion 33 and the top wall 32 (the root portion of the tubular portion 33) and the flange portion 52 of the valve body support member 50. As a result, it is positioned and held inside the cap body 30. In addition, the shape of the base part 41 is not limited to the example of illustration, It can change suitably.

  The valve body support member 50 is fitted and held in the cap main body 30 so as to cover the lower end opening (opening to the top wall 32) of the cylindrical portion 33. Specifically, the valve body support member 50 includes an annular fitting portion 51 that fits into the fitting recess 32 a of the top wall 32, an annular flange portion 52 that extends radially inward of the fitting portion 51, and a flange portion. 52, an inner wall 53 projecting from the inner peripheral edge of 52, a connecting piece 54 projecting from the lower surface of the flange 52, and a disk-like lower wall 55 connected via the connecting piece 54.

Further, the valve member 40 itself may be engaged with and held by the cap body 30 without providing the valve body support member 50.

  The lid 60 closes the discharge port 34 in the closed state shown in FIG. 1 and opens the swing port 34 as shown in FIG. 2 by swinging and opening the hinge portion 61 as a fulcrum.

  The lid 60 includes a cylindrical wall 62 integrally connected to the cylindrical portion 33 via a hinge portion 61, a top wall 63 that covers the upper end portion of the cylindrical wall 62, and an inner cylindrical portion 64 that hangs down from the top wall 63. Have. The tubular wall 62 is provided with a finger hooking portion 65 that protrudes outward from the tubular wall 62 on the opposite side of the hinge portion 61.

  When the inner cylinder part 64 closes the lid 60, the inner cylinder part 64 enters the inner peripheral edge part 33 b of the cylindrical part 33 and closes the discharge port 34. The finger hooking portion 65 is a protrusion for facilitating the opening / closing operation by hooking a finger when the lid body 60 is opened / closed. The lid 60 is not an essential configuration. In addition, the lid 60 is not limited to a configuration that is integrally connected to the cap main body 30, and a configuration in which a member formed as a separate member is detachably mounted by screw coupling or the like.

  Below, the usage method of the powder discharge container 1 of this embodiment is demonstrated. When discharging the contents from the powder discharge container 1, first, as shown in FIG. 2, the lid 60 is opened with the hinge portion 61 as a fulcrum, and the container body 10 is tilted so that the discharge port 34 faces downward. Inverted posture.

  Note that the inverted posture is sufficient if the mouth portion 11 side is positioned below the bottom portion, the axis O may extend in the vertical direction, and it is inclined with respect to the vertical direction as shown in FIG. It may be. When the container body 10 is in the inverted posture, the contents move toward the mouth portion 11 in the accommodation space S. At this time, since the pressure applied to the contents flowing into the slit valve 42 side is reduced by the lower wall 55, the contents pass through the slit valve 42 and spill out from the discharge port 34 before squeezing the body 12. In addition, it is possible to prevent the contents from being pressed and hardened in front of the slit valve 42 (on the accommodation space S side).

  When the body 12 of the container body 10 in the inverted posture is squeezed, the accommodation space S is pressurized and the slit 42a of the slit valve 42 is opened. At this time, the content in the accommodation space S passes through the space 56 (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 the content passage R. And discharged from the discharge port 34.

  Here, the contents that have passed through the slit valve 42 collide with the inner wall surface (inner circumferential surface of the cylindrical portion 33) in the process of passing through the content passage R, and thus the contents collide with each other. Therefore, the momentum of movement toward the discharge port 34 is reduced. Thus, according to the powder discharge container 1 of the present embodiment, the momentum of the contents discharged from the discharge port 34 is reduced by reducing the momentum of the contents that have passed through the slit valve 42 in the contents passage R. It is possible to reduce and discharge the powder-like contents with a moderate momentum in the target direction. As a result, scattering of the discharged contents around can be suppressed.

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

  In the powder discharge container 1 of the present embodiment, the strength when squeezing the body portion 12 is made constant so that a substantially constant amount of content is discharged each time the squeeze operation is performed. Can do. Furthermore, the discharge amount of the contents can be adjusted by adjusting the strength with which the body 12 is squeezed. That is, when the body 12 is strongly squeezed, the container body 10 is greatly reduced in volume and deformed, and a relatively large amount of contents are discharged. Conversely, when the body 12 is weakly squeezed, the container body 10 Therefore, only a relatively small amount of contents are discharged.

  In the powder discharge container 1 of the present embodiment, an inwardly inclined portion 33 a is provided in the distal end side region of the cylindrical portion 33. With this configuration, the content moving through the content passage R collides with the inner surface of the inwardly inclined portion 33a, and the content further collides with each other, thereby reducing the content momentum more effectively. It is possible to improve the accuracy of the discharge direction of the contents. Furthermore, even when the length L of the cylindrical portion 33 is made smaller than when the inwardly inclined portion 33a is not provided (when the diameter of the cylindrical portion 33 is constant up to the tip), the content of Since the effect of reducing momentum 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. The position of the inwardly inclined portion 33a may be a region on the tip side rather than a region on the base side (the top wall 32 side) of the tubular portion 33. However, as in this example, the tip of the tubular portion 33 is located. More preferably, it is provided in the part.

  In the powder discharge container 1 of the present embodiment, the valve member 40 is configured to be held inside the cap main body 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 main body 30, so that the attaching / detaching operation with respect to the container main body 10 becomes easy. That is, the valve member 40 and the valve body support member 50 can be easily mounted at the same time by simply mounting the cap main body 30 on the container main body 10 containing the contents, and the removal from the container main body 10 is also performed collectively. be able to.

  In the powder discharge container 1 of the present embodiment, the length L of the content passage R shown in FIG. 1 is preferably 5 mm or more. According to this, the momentum of the content in the content passage R is increased. It can be reduced more appropriately. Further, the length L of the content passage R is preferably 70 mm or less. According to this, the discharge cap 2 or the powder discharge container 1 as a whole can be obtained by suppressing the size of the cylindrical portion 33 to an appropriate range. As a result, it is possible to maintain good transport efficiency and storage efficiency by preventing the size from becoming too large. The length L of the content passage R is the axial length of the cylindrical portion 33 from the center of the slit valve 42 to the discharge port 34.

  The type of contents stored in the storage space S is not particularly limited as long as it is a powder. For example, when the particle diameter of the contents is 100 μm or less, the contents passed through the slit valve. According to the powder discharge container 1 of the present embodiment, the target direction can be obtained without causing such a problem when the powdered content is discharged vigorously and easily scattered to the outside of the target. The powdered contents can be discharged at a moderate momentum. In addition, even when the bulk density of the contents is 1.0 g / ml or less, the powdered contents that passed through the slit valve were ejected vigorously and easily scattered to the outside of the target. According to the powder discharge container 1 of the embodiment, it is possible to discharge the powder-like contents at an appropriate momentum in the target direction without causing such a problem. Therefore, the present invention is particularly effective when the particle diameter of the content is 100 μm or less, or when the bulk density of the content is 1.0 g / ml or less.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the previous embodiment, the peripheral wall 31 is screwed to the mouth portion 11 of the container body 10, but the peripheral wall 31 may be fitted and held to the mouth portion 11.
