  By the way, in the cap described in Patent Literature 1, when the container body is tilted greatly (for example, 90 ° or more) with respect to the vertical direction, the contents are surely brought into contact with the partition wall, and the contents are evenly dispersed. Further improvements were required in the making.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a cap that can spray contents evenly even when a container body is largely inclined with respect to a vertical direction.

  In order to solve the above problems, a cap body attached to a mouth of a container body, and a top-shaped cylindrical lid body that opens and closes an outlet for contents formed in the cap body, the cap comprising: The top wall portion of the main body is formed with a discharge hole through which contents are discharged, and a lower partition wall extending outward from a peripheral edge of the discharge hole in the radial direction of the cap, and the lower partition wall is formed. Are formed at intervals in the circumferential direction along the periphery of the opening of the discharge hole in a top view, and between the lower partition walls adjacent to each other is an outflow path connected to the outlet, and the cap is provided. In the main body, in a process in which the lid moves upward and opens the outflow port, the lower end of the peripheral wall of the lid exceeds the upper end of the lower partition wall in an upward direction. Engaging part which engages with and engages with the engaged part formed in Characterized in that it is formed.

  According to the cap of the present invention, in the process in which the lid moves upward and opens the outflow port, the lower end of the peripheral wall of the lid exceeds the upper end of the lower partition wall in the cap body. The formed engaging portion and the engaged portion formed on the lid are engaged with each other and are suppressed. As a result, since the upper part of the outlet is closed by the lid, even if the content moves above the lower partition wall, the content flows out of the outlet without contacting the lower partition wall. And the contents can be evenly distributed even when the container body is largely inclined with respect to the vertical direction.

  Here, the lid body is formed with a plurality of upper partition walls projecting downward, and a plurality of upper partition walls abutting or approaching each other in the circumferential direction on the plurality of lower partition walls, respectively. In the process in which the lid moves upward and opens the outflow port, the lower end of the upper partition wall exceeds the upper end of the lower partition wall upward, and is engaged with the engaged portion. It may be suppressed.

  In this case, since a plurality of upper partition walls are formed on the lid body, each of which is in contact with or adjacent to the lower partition wall in the circumferential direction, the flow direction of the contents moved upward from the lower partition wall is disturbed. Can be trimmed by the upper partition wall. Further, in order to prevent the engaging portion and the engaged portion from engaging with each other and moving the lower end of the upper partition wall upward from the upper end of the lower partition wall, the upper partition wall and the lower partition wall are restricted. Are continuously arranged in the up-down direction, so that the turbulence in the flow direction of the contents can be more reliably adjusted.

  In addition, an inclined portion extending outwardly in the radial direction of the cap gradually downward may be formed in a portion of the peripheral wall portion of the lid that faces the outflow passage in the radial direction of the cap.

  In this case, a portion of the peripheral wall of the lid that faces the outflow path in the radial direction of the cap is formed with an inclined portion that gradually extends outward in the radial direction of the cap as it goes downward. It is possible to flow the contents downward along this inclined portion, and even if the container body is greatly inclined with respect to the vertical direction, the flow of the contents hits the peripheral wall of the lid and stays there. Is prevented, and the contents can be smoothly discharged from the outflow path below the inclined portion.

  Further, the engaging portion projects outward from the outer peripheral portion of the cap body in the radial direction of the cap, and the engaged portion is disposed below the engaging portion, and is vertically movable with the engaging portion. They may face each other in the direction.

  In this case, the engaging portion that protrudes outward from the outer peripheral portion of the cap body in the radial direction of the cap, and the engaged portion that faces the engaging portion below the engaging portion in the up-down direction is engaged. Thus, it is possible to easily realize a configuration that suppresses the upward movement of the lid body with respect to the cap body beyond a predetermined amount.

  Further, the lid is connected to the cap main body via a hinge portion disposed on the opposite side of the lower partition wall sandwiching the discharge hole in a cap radial direction, and the lid is connected to the cap main body. It may be rotatable upward around the hinge.

  In this case, since the lid is connected to the cap body via the hinge portion, for example, the lid and the cap body can be integrally formed.

  Further, in the peripheral wall portion of the lid, an operation portion is disposed on a portion on the opposite side of the hinge portion sandwiching the discharge hole in a cap radial direction, and the engagement portion and the engaged portion are When viewed from the operation unit side along the radial direction of the cap, at least one of each of the operation units may be disposed on the left and right sides of the operation unit.

  In this case, since the engaging portion and the engaged portion are disposed at least one on each of the left and right sides when viewed from the front as viewed from the operating portion side, the operating portion is operated to move the lid to the cap body. When the lid is rotated upward, the engaging portion and the engaged portion are prevented from rotating upward beyond a predetermined amount with respect to the cap body by engaging the left and right sides. Thereby, the posture of the lid when the lid is rotated upward with respect to the cap body is stabilized, and the positional relationship in the vertical direction between the lower partition wall and the peripheral wall of the lid is stabilized, It is possible to more reliably prevent the contents discharged from the discharge holes from flowing out without contacting the lower partition wall.

  ADVANTAGE OF THE INVENTION According to this invention, when the container main body is largely inclined with respect to a perpendicular direction, the cap which can suppress that the quantity of the scattered content becomes uneven can be provided.
