No. 1-8525

  However, in the conventional swing cap, when the contents are being swung out, a part of the contents enter and accumulate in the bearing recess, so that the shaft portion becomes difficult to rotate in the bearing recess, and the opening / closing lid There was a risk that good opening and closing operations would be hindered.

  The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a swing-out cap capable of suppressing the contents from entering and accumulating in the bearing recess.

  In order to solve the above-described problems and achieve such an object, the swing-out cap of the present invention is attached to the mouth of the container main body in which the contents are accommodated, and the swing-out for swinging out the contents is performed. A cap body having a mouth and an opening / closing lid for opening and closing the swing opening, and the top wall of the cap body is formed with the swing opening in the first half and the front wall in the second half. The bottom wall portion and the pair of left and right side wall portions define a recessed portion that is open toward the rear, and a front wall portion, a side wall portion, and a bottom wall portion are formed on both side ends of the recessed portion. Bearing concave portions defined by the front wall portion and the side wall portions, which are erected on the front wall portion and the side wall portions, are disposed on both side end portions of the rear half portion of the opening / closing lid that covers the concave portion, A shaft portion is provided in the bearing recess. Was a square one cap, it said the lower end of at least the bottom wall portion in the opposing wall, characterized in that the communication passage for communicating with the bearing recess and the concave-out portion is formed.

In the present invention, the communication wall that connects the bearing recess and the notch is formed at least at the lower end on the bottom wall portion side in the facing wall portion. Even if a part of the material enters the bearing recess, the contents can be discharged to the outside of the bearing recess through the communication path.
In addition, since the communication path is formed at least at the lower end portion on the bottom wall portion side in the facing wall portion, the contents that have entered the bearing recess portion can be sequentially discharged out of the bearing recess portion.
From the above, it is possible to prevent the shaft portion from becoming difficult to rotate in the bearing concave portion by collecting a part of the content in the bearing concave portion when the content is being shaken out.

Here, a support protrusion that supports the shaft portion protrudes from a portion located in the bearing recess in the bottom wall portion, and a communication recess that is connected to the communication path is formed on the support protrusion. Good.
In this case, since the communication recess connected to the communication path is formed in the support protrusion that supports the shaft portion, even if the content that has entered the bearing recess enters between the shaft portion and the support protrusion, By dropping the contents from the support protrusion into the communication recess, the contents can be discharged from the communication path to the outside of the bearing recess through the communication recess.
Therefore, the content that has entered the bearing recess stays between the shaft portion and the support protrusion until the content reaches the communication path, so that the shaft portion becomes difficult to rotate in the bearing recess. Can be prevented.

In addition, vertical ribs may be provided separately on the rear wall portion facing the front wall portion and the opposing surfaces of the front wall portion facing each other.
In this case, since the vertical ribs are provided separately on the opposing surfaces of the front wall portion and the rear wall portion, when the content is being shaken out, a part of the content is in the bearing recess. Even if it enters between the entering shaft portion and the facing surface, the contents can be dropped through a gap between the non-formed portion of the vertical rib and the shaft portion on the facing surface.
Therefore, it is possible to prevent the shaft portion from becoming difficult to rotate in the bearing recess portion because the contents entering the bearing recess portion stay between the shaft portion and the facing surface.
Further, since the vertical rib protrudes from the opposing surface in this way, it is possible to reduce the frictional force generated between the shaft portion and the bearing recess during the opening / closing operation.

Furthermore, a concave portion may be formed on the outer peripheral surface of the shaft portion.
In this case, since the concave portion is formed on the outer peripheral surface of the shaft portion, it is possible to reduce the frictional force generated between the shaft portion and the bearing concave portion during the opening / closing operation.

  According to the swing cap according to the present invention, the contents can be prevented from entering and collecting in the bearing recess.

In addition, since a communication recess 27 connected to the communication path 26 is formed in the support protrusion 25 that supports the shaft portion 31, the content that has entered the bearing recess 23 is between the shaft portion 31 and the support protrusion 25. Even if it enters, the contents can be discharged from the communication passage 26 to the outside of the bearing recess 23 through the communication recess 27 by dropping the contents from the support protrusion 25 into the communication recess 27.
Therefore, the content that has entered the bearing recess 23 stays between the shaft portion 31 and the support projection 25 before reaching the communication path 26, so that the shaft portion 31 rotates in the bearing recess 23. It can be prevented from becoming difficult.

Furthermore, since the vertical ribs 28 project from the opposing surfaces 21b and 22b of the front bearing wall 21 and the rear bearing wall 22 that are opposed to each other, the contents are drawn out when the contents are being shaken out. Even if a part of them enters the bearing recess 23 and enters between the shaft portion 31 and the opposed surfaces 21b and 22b, the contents are not formed in the portions where the vertical ribs 28 are formed on the opposed surfaces 21b and 22b. And can be dropped through a gap between the shaft portion 31 and the shaft portion 31.
Therefore, the contents that have entered the bearing recess 23 stay between the shaft portion 31 and the facing surfaces 21b and 22b, thereby preventing the shaft portion 31 from becoming difficult to rotate in the bearing recess 23. it can.
Further, since the vertical ribs 28 project from the opposing surfaces 21b and 22b in this way, it is possible to reduce the frictional force generated between the shaft portion 31 and the bearing recess 23 during the opening / closing operation. Become.
