Separately and separately housed two agents as a two-agent mixing container to be mixed at the time of use, the first agent and the second agent are separately stored in the upper and lower containers that are tightly assembled by connecting up and down In addition, the patent document discloses a configuration in which the inner lid is separated from each other by the inner lid, and the inner lid is detached into one container during use, and both containers are in communication with each other to achieve mixing of the two agents. Known as 1.
JP-A-9-118375

  In the above-described prior art, the separation of the two agents by the inner lid is reliable and stable, so that the two agents can be stored in an integrated manner, and the inner lid is detached. There is an advantage that it can be completely opened.

  However, in the above-described prior art, the inner lid that is detached and floating in one container may cover the communication port portion of both containers, which may interfere with the dispensing of the mixed two agents. There was a problem.

  Further, when the container is made transparent, there is a problem that the inner lid that is detached and floating in the container is observed from the outside, and the appearance is deteriorated.

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and the sealing of the communication port portion of both containers by the inner lid equivalent portion can be performed without removing the inner lid equivalent portion from both the containers. Achieving this is a technical problem and aims to eliminate any inconvenience caused by the portion corresponding to the inner lid floating in the container.

  The two-component mixing container of the present invention includes a first container that contains the first agent, a second container that contains the second agent, and a plug member that has a plug piece that seals the lower opening of the second container. The first container and the second container are composed of a coupling member that tightly couples the first container and the second container so that they can communicate with each other.

  The first container has a bottomed cylindrical shape with a mouth tube part formed at the upper end and contains a desired amount of the first agent, and the second container has a spout at the upper end and at the lower part. An opening is formed by the inner collar piece to accommodate a desired amount of the second agent.

The plug body is assembled with an assembly ring that is fitted inside the second container and assembled, a plug piece that can be lifted and displaceable to seal the opening of the second container from above, and a passage is formed between the plug piece and the plug piece. And at least one connecting plate piece for connecting the attached ring.

The coupling member is assembled densely and immovably on the mouthpiece portion of the first container, and is attached to the lower end portion of the second container densely and slidably up and down by the sliding contact piece . Due to the upward displacement relative to the second container, a push-up bar piece that pushes up the plug piece of the plug body to open the opening is provided in the center .

  In the state where both agents are separated and accommodated, the second container is held at an elevated position with respect to the combination of the first container and the coupling member, and the opening of the second container is moved upward by the plug piece of the plug body. It is sealed from.

  From this state, when the second container is displaced downward relative to the combination of the first container and the coupling member, the plug piece of the plug body is pushed up by the coupling member, thereby opening the opening of the second container. Therefore, the first container and the second container are communicated with each other through the opening of the opening and the stopper, and the second agent in the second container flows down from the opened opening into the first container. , Mix with the first agent.

  The mixed agent of the first agent and the second agent is poured out from the spout, which is the upper end opening of the second container, for example, by inverting the container upside down and squeezing it.

  In this state, since the plug piece of the plug is pushed up by the coupling member, the opening of the second container is kept open, and the opening is not blocked by illusion.

  Moreover, since the plug body maintains the assembly with respect to the second container only by moving the plug piece upward, it does not float in the second container.

  In another configuration of the present invention, two or more connecting plate pieces of the plug body are provided and an inclined posture structure that can be reversed and deformed, and the assembly ring is assembled to the second container in an immobile manner. It is a thing.

  If there are two or more connecting plate pieces of the plug body that can be inverted and deformed, and the assembly of the assembly ring is immovable, it is displaced upward and reverse by pushing up from the coupling member, and the opening is opened. The opened plug piece is held in its open posture by the self-holding force of the reversely deformed connecting plate piece.

  Further, since the reverse deformation of the connecting plate piece is self-operating if the displacement amount passes the inversion point, the amount of displacement up to the inversion point of the connecting plate piece, the downward displacement amount of the second container relative to the coupling member, and Depending on the setting, it is possible to make the opening stroke of the stopper piece larger than the downward displacement amount of the second container relative to the coupling member.

  Moreover, another structure of this invention adds that the assembly | attachment with respect to the 2nd container of the assembly | attachment ring of a stopper was slidably displaceable.

  If the assembly of the assembly ring with respect to the second container is slidably displaceable, the opening of the second container can be opened as long as the entire plug body is moved upward, and a deformation operation is required. It is not to be.

  Another configuration of the present invention is such that a short cylinder-like tightly fitting cylinder piece tightly fitted into the opening of the second container is provided on the lower surface of the stopper piece.

  In the case where the tightly fitting cylinder piece that is tightly fitted into the opening of the second container is provided on the lower surface of the stopper piece, the sealing of the opening by the stopper piece is stably and firmly achieved and maintained.

  Further, according to another configuration of the present invention, the stopper piece is configured in a flat plate shape that can be fitted into the opening of the second container, and the lower peripheral edge of the stopper piece is closely mounted on the peripheral surface of the opening. This is in addition to the fact that a circumferential rib is provided around the surface.

  The plug piece shall be tightly fitted into the opening, and if the peripheral surface of the opening is provided with a seal peripheral rib for closely mounting the plug piece, the sealing of the opening by the plug piece will be sealed. The peripheral ribs effectively reinforce, and the structure of the stopper piece can be made such that the mixture to be dispensed does not stay unnecessarily.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the present invention, both agents can be mixed by simply moving the second container downwardly with respect to the combination of the first container and the coupling member from the separated housing state of both agents. The process is extremely simple and the handling of the container is simple.

  In the state where both agents are mixed, the plug piece of the plug is pushed up by the coupling member, so that the plug piece does not clog up the opening partly, thereby smooth and good dispensing operation of the mixture Can be obtained.

  In addition, since the plug opens the opening in a state where the assembly with respect to the second container is maintained, the plug does not float in the second container, so that even when the plug is visually seen from the outside, it does not look good. It won't get worse.

  In the case where two or more plug connecting plate pieces are provided and can be inverted and deformed, and the assembly ring is fixed, the opening of the second container is reliably and stably opened. The opening of the second container can be sufficiently opened even when the downward displacement of the second container relative to the coupling member is small.

  In the case where the assembly of the assembly ring with respect to the second container is made slidably displaceable, the entire plug body only needs to be lifted and displaced as it is, so that the structure becomes simple.

  In the case where the tightly fitting cylinder piece tightly fitted into the opening of the second container is provided on the lower surface of the stopper piece, the sealing of the opening by the stopper piece can be achieved and maintained stably and firmly, Separation and storage of both agents can be maintained firmly and stably.

  If the plug piece is to be tightly fitted into the opening, and the peripheral surface of the opening is provided with a seal peripheral rib for tightly mounting the plug piece, a high degree of sealing of the opening by the plug piece is required. In addition, since the portion where the mixed agent is accumulated is not formed on the lower surface side of the stopper piece, the mixed agent can be poured and consumed without waste.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
