Description

  The present invention relates to a cap attached to a mouth tube portion of a container body.

Conventionally, as disclosed in, for example, Patent Document 1, an inner cap body provided with an attached cylinder portion to be attached to a mouth tube portion of a container body, and an outer cap body provided with an extraction hole, A cap is provided in which the inner cap body and the outer cap body are disposed so as to be movable in the circumferential direction and the axial direction, and the outer cap body is rotated to change the position in the axial direction, thereby opening and closing the pouring hole. Yes.
Japanese Patent No. 2504907

  By the way, in the cap described in patent document 1, although the opening / closing operation | movement of the extraction | pouring hole can be performed, the axial direction position of an inner cap body and an outer cap body was not able to be fixed in the intermediate position. . For this reason, the flow rate of the contents cannot be adjusted by switching the flow path area to the extraction hole, which is inconvenient to handle.

  The present invention has been made in view of the above-described circumstances, and can switch the dispensing flow rate from the dispensing hole by guiding the relative position in the axial direction between the inner cap body and the outer cap body in multiple stages. The purpose is to provide a cap.

  In order to solve this problem, a cap according to the present invention is a cap that is attached to a mouth tube portion of a container body and has a pouring hole for pouring out the contents of the container body. An inner cap body having an attached cylinder portion to be attached and a middle cylinder portion arranged coaxially with the axis thereof, and can be moved up and down in the axial direction with respect to the inner cap body, and can be rotated in the circumferential direction. An outer cap body attached to the inner cap body and the outer cap body, the inner cap body and the outer cap body each having a circumferential guide portion for guiding a circumferential position of the inner cap body and the axis line of each other according to the circumferential position. An axial guide portion that guides a directional position, and the circumferential guide portion is formed on one of the inner cap body and the outer cap body, and protrudes toward the other, and the inner cap Body and external cap body A plurality of locking portions that are formed on the other side and that engage with the protruding portions and guide the circumferential position, and each of the protruding portions is locked by rotating the outer cap body around the axis. The circumferential position of the outer cap body and the inner cap body is guided in at least three stages by engaging with the portion, and the relative position of the inner cap body and the outer cap body in the axial direction is changed accordingly. By doing so, it is characterized in that the dispensing flow rate from the dispensing hole is switched to at least three stages.

  The cap of this configuration has an inner cap body, and an outer cap body that is mounted on the inner cap so as to be movable up and down in the axial direction and rotatable in the circumferential direction, and the outer cap body and the inner cap body. A circumferential guide portion for guiding the circumferential relative position in at least three stages and an axial guide portion for guiding the axial position in accordance with the circumferential position are provided. The circumferential position of the outer cap body can be guided in at least three stages by the portion, and accordingly, the relative axial position of the outer cap body and the inner cap body is also guided in at least three stages. . Therefore, the axial position of the inner cap body and the outer cap body can be fixed not only in the open state (large dispensing flow rate) and in the closed state (no dispensing flow rate 0) but also in the intermediate position (medium dispensing flow rate). In addition, it is possible to adjust the flow rate of pouring from the pouring hole.

Here, the external cap is provided on the inner cap body so as to be coaxial with the middle tube portion and radially outward and to form an axial guide portion on one of the middle tube portion and the outer tube portion. A projection portion or a locking portion that forms a circumferential guide portion on the other side, and a sliding cylinder portion that is engaged with the intermediate cylinder portion and an outer cylinder portion that are engaged with the outer cap body A guide tube portion may be provided.
In this case, the circumferential guide portion and the axial guide portion are arranged so as to be aligned in the radial direction, and the height of the cap can be reduced.

Further, the axial guide portion is constituted by a protruding pin formed on one of the inner cap body or the outer cap body and a guide groove formed on the other, and the protruding pin is inserted into the guide groove. The protruding pin acts as a projection of the circumferential guide portion, the guide groove acts as the locking portion, and the axial guide portion and the circumferential guide portion are integrally formed. May be.
In this case, since the axial direction guide portion and the circumferential direction guide portion are integrally formed, the outer cap body and the inner cap body can be made smaller, and the cap can be further reduced in size. Become.

  According to the present invention, the plurality of locking portions are formed in the circumferential guide portion that guides the circumferential position between the inner cap body and the outer cap body, and at least the axial position of the inner cap body and the outer cap body is set to the axial direction position. It is possible to switch to three stages, and the discharge flow rate from the extraction hole can be switched to at least three stages.
