  By the way, in such a mixing container, there existed room for improvement about the further simplification of the attachment / detachment operation of a cover body, and the reliable suppression of the spilling of the content.

  This invention is made | formed in view of the situation mentioned above, The objective is to provide the mixing container which can make the contents difficult to spill while the attachment / detachment operation of a cover body is easy.

In order to solve the above problems, the present invention proposes the following means.
A mixing container according to the present invention is a mixing container comprising: a container body that stores a plurality of types of contents; and a lid body that is detachably attached to a mouth of the container body, the container body and One of the lids is provided with a plurality of engagement pieces that can rotate around the hinge portion at intervals in the circumferential direction, and the other is detachably engaged with the engagement piece. An engaged portion is provided, and the hinge portion is constituted by a plurality of hinge pieces arranged at intervals in the circumferential direction .

  In the present invention, when mixing a plurality of types of contents, first, each engagement piece is rotated around the hinge portion to release the engagement between the engagement piece and the engaged portion, and the lid body is the container body. After releasing from the mouth and opening the mouth, a plurality of kinds of contents are accommodated in the container from the mouth. Thereafter, the mouth is closed by the lid, and each engagement piece is rotated around the hinge to engage the engaged portion. After the lid is attached to the container, the contents are mixed.

As described above, the lid can be attached to and detached from the container by rotating each engaging piece around the hinge portion, so that the attaching and detaching operation can be easily performed in a short time.
Further, as described above, the lid can be attached to and detached from the container body by rotating each engaging piece around the hinge portion, so that the lid body can be attached to and detached from the container body without firmly grasping the container body. It is possible to prevent the contents stored in the container from spilling from the mixing container during the attachment / detachment operation. That is, if the container body is firmly held during the lid attaching / detaching operation, the internal pressure of the mixing container rises and the contents may spill out of the mixing container.

  Further, since the lid is attached to the container body by engaging the engaging piece with the engaged portion, it is possible to suppress the lid body being attached to the container body in an inclined state. The sealing property between the lid and the mouth of the container body can be easily secured stably. Therefore, it is possible to reliably suppress the contents stored in the container from spilling out of the mixing container during the mixing operation of mixing a plurality of types of contents.

  Moreover, the protective member integrally formed in this container body may be arrange | positioned at the radial direction outer side of the trunk | drum of the said container body.

  In this case, since the protective member is formed on the outer side in the radial direction of the body portion, the body portion is hardly deformed. That is, when grasping the container body containing the contents, the container body is grasped via the protective member, thereby suppressing the body portion of the container body from being deformed inward and increasing the internal pressure. It becomes possible. Thereby, it can suppress that the contents spill from a mixing container.

  Further, a pressure relief hole penetrating the lid is formed in the lid, and a sheet body that covers the pressure relief hole from the outside is fixed, and between the lid and the sheet body, A pressure relief path that communicates the pressure relief hole with the outside may be formed.

In this case, since the pressure relief hole is formed in the lid body and the pressure relief path is formed between the lid body and the sheet body, even if the internal pressure of the mixing container increases, the internal pressure is reduced. It becomes possible to escape to the outside through the pressure relief hole and the pressure relief path, and the increase in internal pressure can be suppressed. Such an increase in internal pressure may be caused by, for example, a gas generated by mixing the contents. That is, for example, the present invention can be suitably applied to a mixing container that mixes a plurality of types of contents that generate gas when mixed with each other, such as a hair dye.
In addition, the internal pressure of the mixing container does not escape directly from the pressure relief hole, but escapes to the outside through the pressure relief passage. Therefore, even if the contents pass through the pressure relief hole, the flow resistance of the pressure relief passage is received. As a result, it is possible to prevent the contents from spilling out.

  Further, when the internal pressure rises, the lid body is pushed up with respect to the container body, so that a communication path that connects the inside and the outside of the mixing container is formed between the mouth portion and the lid body. May be.

  In this case, when the internal pressure rises, the lid is pushed up with respect to the container body to form the communication path. Therefore, even if the internal pressure of the mixing container rises, this internal pressure is externally passed through the communication path. It is possible to escape, and an increase in internal pressure can be suppressed. Such an increase in internal pressure may be caused by, for example, a gas generated by mixing the contents. That is, for example, the present invention can be suitably applied to a mixing container that mixes a plurality of types of contents that generate gas when mixed with each other, such as a hair dye.

Further, the mixing container according to the present invention is a mixing container comprising a container body in which a plurality of types of contents are accommodated, and a lid body detachably attached to the mouth of the container body, wherein the container One of the body and the lid is provided with a plurality of engagement pieces that can be rotated around the hinge portion at intervals in the circumferential direction, and the engagement piece is detachably engaged with the other. And a main body plate that extends in the container axial direction and is connected to the hinge portion, and protrudes radially inward from the main body plate. And a projecting body having a locking portion positioned with a locking gap between the main body plate, and the engaged portion is disposed in the locking gap and is engaged with the locking portion. A locked portion to be stopped, and opposed to the locking portion in the radial direction through the locked portion in the main body plate Min is characterized in that it is closed.

In this case, since the locked portion of the engaged portion is locked to the locking portion of the engaging piece, even if the main body plate unexpectedly rotates around the hinge portion in the radial direction, The rotation is regulated by the contact between the stop portion and the locked portion.
Moreover, since the said opposing part of the main body board is obstruct | occluded, a to-be-latched part is not covered and exposed from the radial outer side by the said opposing part, and the design property of a mixing container can be improved.

  In addition, a gripping portion located on the opposite side of the hinge portion along the container axial direction from the connecting portion with the projecting body in the main body plate gradually goes outward in the radial direction toward the opposite side. May be extended.

  In this case, since the grip portion of the main body plate gradually extends outward in the radial direction toward the opposite side, the engaged portion of the grip portion, the container body, and the lid body is The interval between the other provided and gradually increases toward the opposite side. Therefore, the grip portion of the main body plate can be easily gripped with a finger or the like from the opposite side, and the main body plate can be easily rotated around the hinge portion. Thereby, attachment / detachment operation of a cover body can be performed more simply.

  According to the mixing container of the present invention, the lid can be easily attached and detached, and the contents can be prevented from spilling.
