Description

  The present invention relates to a mixing container, and more particularly to a mixing container in which solids such as powders and granules and liquids are separately stored and mixed at the time of use.

  A two-component mixing container has been proposed in which liquid and powder can be stored simultaneously and separately, and the two components can be mixed, stirred, and poured out by simple operations. (For example, see Patent Document 1)

In the container, a cap in which a storage cylinder portion for storing the second agent is suspended from the back of the top wall is screwed onto the upper portion of the container body for storing the first agent via a specially configured connecting member. An idling area is provided in the middle of the ascent of the screw, and the cap is screwed up until reaching the idling area, so that the bottom cover at the lower end of the storage cylinder part is removed and the two agents are mixed.
Japanese Patent Laid-Open No. 08-091418

  The above container can store the two agents separately and simultaneously, so it is convenient for storage and there is no risk of losing one of them. When using it, the two agents are mixed by a simple operation of screwing up the cap. In addition, after stirring and mixing by shaking the container as it is, the cap can be lifted and removed, and the mixture can be poured out, so mixing, stirring and dispensing of the two components can be performed very easily. It is excellent.

  However, when this type of mixing container contains powder and liquid and is mixed at the time of use, the powder generally does not like moisture and is often adversely affected by moisture. For example, the powder may cause discoloration or alteration before mixing. Although the liquid and powder storage areas are sealed in an air-tight manner so as not to cause such inconvenience, especially when the internal pressure increases due to an increase in the temperature surrounding the container, There is a possibility that inconvenience that the moisture passes through the seal portion and reaches the powder storage portion.

  In addition, since the nozzle that discharges the mixed liquid is installed on the outer periphery of the storage cylinder part that hangs down from the center of the cap top wall, if you try to reduce the diameter of the discharge port that discharges the liquid mixture, the diameter of the storage cylinder part As a result, there is a restriction that the total height must be increased in order to secure the necessary amount of the second agent. Further, when it is necessary to make the discharge port smaller, it becomes impossible to provide a cylindrical portion for storing the powder, and such a configuration becomes impossible.

  The present invention has been made in view of the above points, and provides sufficient sealing properties to the powder storage chamber and the liquid storage chamber, so that the powder can be reliably obtained until opening even if the internal pressure increases due to the influence of the external atmosphere. The present invention proposes a mixing container that can be isolated and that can be easily removed during mixing and the liquid and powder can be mixed easily by removing the stopper member. In addition, the present invention proposes a mixing container that employs a nozzle having a small discharge port to allow the liquid mixture to be poured out by inverting the container and that can be easily filled with powder.

The first means is configured as follows. That is, the neck 2 is raised from the body 2 and the container body A having the liquid storage chamber R ₁ inside is fitted to the inner periphery of the mouth neck 4 in a liquid-tight manner, and the lower end is connected to the neck. A powder storage cylinder 20 attached to the container body 4 while being suspended from the container neck A while preventing the rotation and withdrawal of the container body A from the neck 4 The seal portion 30 is fitted to the seal surface 21 at the lower end portion of the powder storage cylinder 20 to close the lower end opening of the powder storage cylinder 20 and is mounted so that it can be screwed down. A plug member C that defines R _2, and a rotation transmission mechanism that closes the upper end opening of the powder storage cylinder 20 and rotatably attaches to the powder storage cylinder 20 and that causes the plug member C to be screwed down by rotation. And a nozzle member D having a nozzle 42 standing on the top, and the rotation transmission mechanism is suspended from a circumferential position on the back of the top of the nozzle member D A plurality of engaging ribs 45 are engaged with engaging ribs 34 protruding in the circumferential direction on the outer periphery of the upper part of the plug member C, and the plug member C extends from the lower surface of the powder storage cylinder 20 to the lower end on the inner surface. A cylindrical seal portion 30 having an L-shaped cross section that is liquid-tightly fitted to the seal surface 21 extending over the tube, and the cylindrical seal portion 30 is suspended from the lower end of the outer periphery, and the outer periphery is the seal surface of the inner periphery of the powder storage cylinder 20 21 Screw part 32 screwed in the upper position, extending upward from the upper end edge of the screw part 32 via the inward flange 33, and the tip part closes and closes the base end part of the nozzle 42 And an upper cylindrical portion 35 having a small diameter with an upper end closed by protruding the engaging rib 34 on the outer peripheral surface, and the stopper member C is screwed down by the rotation of the nozzle member D and detached from the powder storage cylinder 20. Thus, the powder storage chamber R ₂ and the liquid storage chamber R ₁ are configured to communicate with each other.

  The second means is configured as follows. That is, in the first means, the container body A is mounted so as to be able to be screwed up, mounted on the nozzle member D so as to prevent mutual rotation and allow mutual vertical movement, and In addition, a cap E that is detachably mounted by closing the tip opening of the nozzle 42 is provided, and when the cap E is screwed off, the nozzle member D is rotated and the plug member C is screwed down.

In the mixing container of the present invention, the cylindrical seal portion 30 at the lower end portion of the plug member C is fitted to the seal surface 21 at the lower end portion of the powder storage tube 20 to close the lower end opening of the powder storage tube 20; Further, since the plug member C is mounted so as to be able to be screwed down, the cylindrical seal portion 30 and the seal surface 21 may be configured to have a sufficient contact area and obtain sufficient liquid tightness. The stopper member C can be easily detached. As a result, the liquid storage chamber R ₁ and the powder storage chamber R ₂ are securely separated from each other, and even if the internal pressure increases due to the atmosphere around the container, moisture can be reliably prevented from entering the powder storage chamber R ₂ . it can. Moreover, the opening operation is very easy. Further, since the nozzle 42 having a small discharge port can be selected and the mixed liquid can be poured out from the nozzle, the mixed liquid can be poured out by inverting the container.

Attached to the container body A so as to be able to be screwed up, attached to the nozzle member D so as to prevent mutual rotation and allow mutual vertical movement, and closes and removes the tip opening of the nozzle 42 capable provided attached to cap E, the nozzle member D when threaded disengagement of the cap E is rotated when the plug member C composed as to threadedly descending, the powder containing chamber R in ₂ by the action of removing the cap E And the liquid storage chamber R ₁ can be communicated with each other.

  When the rotation transmitting mechanism is configured by engaging a plurality of locking ribs 45 suspended from the circumferential position on the back surface of the top of the nozzle member D with engaging ribs 34 protruding in the circumferential direction on the outer periphery of the top of the plug member C. In this case, when the stopper member 45 is screwed down by the rotation of the locking rib 45, the engagement rib 34 is also rotated so that the stored powder can be dropped more efficiently.

  The plug member C has a cylindrical seal portion 30 having an L-shaped cross section that is liquid-tightly fitted to the seal surface 21 extending from the lower surface of the powder storage cylinder 20 to the lower end portion of the inner surface, and the cylindrical seal portion 30 from the lower end portion of the outer periphery.
