Description

  The present invention relates to a mixing container, and more particularly, to a mixing container suitable for containing solids such as powders and granules and liquid separately and mixing them 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 first agent storage chamber and the second agent storage chamber, and even if the internal pressure increases due to the influence of the external atmosphere, until the opening. A mixing container is proposed in which the powder can be reliably isolated, and can be easily opened by a simple operation when used, and the first agent and the second agent can be easily mixed. 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 standing of the neck 12 from the barrel 10, and the container body A where the internal and the first containing chamber R _1, together with the fitted liquid-tight to prevent rotation in the neck 12, A mounting base B having a support cylinder 25 penetrating the top plate 21, a seal member C capable of being pressed and broken by closing the lower end opening of the support cylinder 25, and a mounting base B capable of being screwed down. In addition, a rotating body E in which a bottomed extraction cylinder portion 55 is suspended in the support cylinder 25 and a nozzle 73 communicating with the inside of the extraction cylinder portion 55 is provided at the upper end, and a mounting base B And a stopper D that prevents the rotating body E from being screwed down and is provided with a seal portion that is annularly pressed and sealed between the inner surface of the support cylinder 25 and the rotating body E facing the inner surface of the supporting cylinder 25. defining a support cylinder 25 thereunder as a second containing chamber R _2, a rotating body E be to threadedly lowered, cutting provided on the rotating member E bottom 63 a sealing material C communicates with push broken and the first agent storage chamber R ₁ and the second agent accommodating chamber R ₂ by, where together with the sealing portion is released, the support tube 25 tops rotator It is configured so that a sealed flow path is formed from the inside of the container body A to the inside of the support cylinder 25 by pressure-contact sealing to the top back surface of E, and the rotating body E is screwed to the outer periphery of the support cylinder 25 so as to be able to be screwed down. The attached inner peripheral wall 50 is suspended from the outer edge of the inner top wall 51, and the outer peripheral wall 53 is suspended from the outer edge of the outer top wall 52 extending from the vertical middle portion of the outer surface of the inner peripheral wall 50. The upper outer periphery of the extraction cylinder part 55 is connected to the inner edge of 51, and the cap F is mounted by detachably fitting the peripheral wall 80 to the outer surface of the inner peripheral wall 50 above the outer top wall 52.

  The second means is configured as follows. That is, in the first means, a ratchet is provided between the rotating body E and the mounting base B, which allows the rotating body E to rotate in the screwing down direction but prevents the reverse rotation.

  The third means was configured as follows. That is, in any one of the first means and the second means, the seal portion is provided with elasticity such that the seal portion is erected from the peripheral portion of the bottom plate 60 that closes the lower end opening of the extraction tube portion 55. The seal cylinder part 62 and the annular seal projection part 26 provided on the inner surface of the support cylinder 25 are configured.

In the mixing container of the present invention, the second agent storage chamber R ₂ is defined by the sealing material C and the sealing portion during distribution, etc., and sufficient airtightness and liquid tightness are maintained. Even if the container is accidentally tilted with F removed, it is not opened unless the rotating body E is screwed down, so that airtightness and liquid tightness are similarly maintained. Even if the internal pressure increases due to the influence of the external atmosphere, the second agent can be surely isolated until opening, and can be easily opened by a simple operation during use. Easy mixing of the agent and the second agent is possible. Further, there is an advantage that the liquid mixture can be poured out by inverting the container by adopting a nozzle having a small discharge port, and powder can be easily filled. In addition, the rotating body E hangs from the outer edge of the inner top wall 51 so that the inner peripheral wall 50 is screwed to the outer periphery of the support cylinder 25 so as to be able to be lowered. The outer peripheral wall 53 is suspended from the outer edge of the wall 52, and the upper outer periphery of the extraction cylinder portion 55 is connected to the inner edge of the inner top wall 51, and the peripheral wall 80 is formed on the outer surface of the inner peripheral wall 50 above the outer top wall 52. Since the cap F is mounted so as to be detachable, the rotating body E can be rotated while the cap F is mounted, and therefore, the opening with the cap F mounted can be performed. Therefore, the operation of shaking and shaking the container immediately after the second agent falls into the first agent can be performed.

  When a ratchet is provided between the rotating body E and the mounting base B to allow the rotating body E to rotate in the screw-down direction, but prevents the reverse rotation, the support cylinder is provided after final opening. The state in which the top of 25 is pressure-sealed to the top back of the rotating body E can be reliably maintained, and the airtightness of the flow path can be more reliably maintained.

  An elastic seal cylinder 62 projecting from the inner surface of the support cylinder 25 and an elastic seal cylinder 62 provided upright from the peripheral edge of the bottom plate 60 that closes the lower end opening of the extraction cylinder 55 26, there is an advantage that an extremely high sealing performance of the seal portion can be obtained, and there is an advantage that the assembling operation can be performed more easily.
