As the shape of the container body 300, any shape can be adopted as long as it has an opening. As the material of the container body 300, known materials such as glass and resin can be used depending on the contents, but it is preferable to use a material having high rigidity in order to reliably pour out the contents.

Next, a method of using the cap 100 will be described with reference to FIGS. 2A to 2C.

FIG. 2A shows a cross-sectional view of the cap 100 in the closed lid state. In the closed state, the spout 30 is covered with the lid 50 and sealed. At this time, the closed state can be maintained by engaging the protrusion 53 of the lid 50 with the claw 60 of the cap body 10. Further, since the spherical protrusion 54 formed on the lid 30 is fitted into the spout, the spout 30 is sealed and the inside of the container body 300 is closed.

The user can open the lid by putting a finger on the flange portion 55 or the like of the lid portion 50 in the closed lid state and lifting the lid portion 50 in the direction of the arrow with the hinge portion 40 as a fulcrum. At this time, the protruding portion 53 of the lid portion 50 is detached from the claw portion 60 of the main body of the cap 100, and the lid portion 50 can rotate around the hinge portion 40 as a fulcrum. FIG. 2B shows a cross-sectional view of the cap 100 with the lid opened about halfway.

FIG. 2C shows a cross-sectional view of the cap when the contents are poured out. In order to eject the contents, the user rotates the lid portion 50 toward the pressurizing portion 20 on the opposite side of the spout 30 with the hinge portion 40 as a fulcrum. As a result, the top plate portion 51 of the lid portion 50 that has rotated toward the pressurizing portion 20 comes into contact with the pressurizing portion 20. In this state, the user tilts the container so that the contents gather in the vicinity of the spout 30. After confirming that the container is tilted by a predetermined amount and the contents are collected at the spout, the user presses the pressurizing portion 20 by pushing the lid portion 50 toward the pressurizing portion 20 with a finger 90. By pressing, the pressurizing portion 20 elastically deforms toward the inside of the container and dents, and the gas inside the container is pressurized. As a result, a part of the contents is poured out from the spout 30.

(Second Embodiment)
FIG. 3 shows a plan view of the cap 200 according to the second embodiment in an open state and a cross-sectional view cut along the line BB'. The difference between the cap 100 and the cap 200 is the shape of the spout 31, and as shown in FIG. 3, the spout 31 of the cap 200 is composed of a plurality of holes formed in the top plate 11.

The cap 200 can be suitably used for a container containing powder. When the pouring port 31 is clogged with powder of the contents, the user of the cap 200 presses the pressurizing portion 20 with the lid portion 50 to pressurize the gas in the container, thereby clogging the powder. It can be resolved. Further, when the powder in the container is poured out, a small amount of powder can be poured out by using the pressurizing unit 20, and the extraction amount can be adjusted. The lid portion 50 may be provided with a boss 70 for preventing powder clogging by fitting into the spout 31 in the closed state.

In this way, if the caps 100 and 200 are used, the pressurizing portion 20 can be pressed by using the lid portion 50 rotatably attached with the hinge portion 40 as a fulcrum. Therefore, according to the principle of leverage, the contents can be poured out with a smaller force than when the pressurizing portion 20 is directly pressed with a finger. In particular, the effect is great when the pressurizing position is set to a position away from the hinge portion 40, and by pressurizing using the flange portion 55 formed so as to protrude from the lid portion 50, it is possible to dispense with a smaller force. It becomes.

Further, by using the lid portion 50 for pressing, the lid portion 50 does not come into contact with the hand holding the container or the finger trying to press the pressing portion 20 when the contents are dispensed, so that the lid portion 50 is dispensed. It does not interfere with the operation.

Further, since the injection ports 30 and 31 and the pressurizing portion 20 are separated by the lid portion 50, the pressurizing portion 20 is less likely to be contaminated by the dispensed material.

Further, since the entire cap including the lid portion 50 and the pressurizing portion 20 can be integrally formed, it can be manufactured at low cost.

Further, by forming the hinge portion 40 along the entire length of a straight line connecting two points on the outer edge of the top plate 11, it is possible to increase the width of the hinge portion 40 and secure the strength.

As described above, according to the present invention, there is provided a cap and a container with a pouring mechanism, which can easily pour out the contents with a small force and prevent the pressurized portion from being contaminated by the pouring liquid. can do.

The shape of the cap body is not limited to a circular shape when viewed from above, and can be appropriately deformed. Further, the spout 30 may be covered with the lid 50 even if it protrudes from the outer edge of the cap body 10. Further, the method of attaching the cap body 10 to the container body 300 may be fitting or the like, and is not limited to screwing.

It is useful for containers containing liquids or powders.
