  There is also known a liquid discharge container which is provided with the above-described middle dish raising mechanism and is configured to store and discharge, for example, a high-viscosity liquid on the middle dish. These are slidably fitted to the inner periphery of the container body so that the outer peripheral edge of the inner dish is slidable, and the top of the container body is closed and a discharge hole is formed there.

  In the case of the liquid discharge container provided with the above-described raising mechanism of the intermediate tray, the liquid pressure at the time of discharge tends to remain in the container as a residual pressure for a relatively long time. As a result, even after the rotation of the rotating part is stopped and the pressurizing operation is completed, the liquid is discharged from the discharge hole at a low speed, not only dirtying the surface of the container body, but also impairing the reliability as a discharge container, There is a risk that the value is significantly reduced.

  The present invention has been made in view of the above points, and it is possible to prevent liquid from leaking from the discharge hole after discharge, to prevent the use of useless liquid, and to exhibit high functionality and commercial value. We propose a container with an elevating mechanism for an inner pan that is improved, easy to handle, and simple in structure.

  The container of the present invention includes a container body, an operation handle, a screw shaft, and an inner dish.

  The container body is formed of a synthetic resin or the like, and a container body having an inner peripheral surface of the same shape and the same size from the lower part to the upper part is used. Moreover, what is provided with the discharge hole in the top part with the top is used.

  The operation handle is made of synthetic resin or the like and is for rotating a screw shaft standing in the container body. The operation handle is rotatably mounted on the bottom of the container body so as to be able to be rotated from the outside. Various shapes can be adopted, for example, a substrate is rotatably fitted to the back of the container body, and the outer peripheral edge of the substrate is rotatably exposed to the outer periphery of the container body, or extends from the peripheral edge of the substrate. What arrange | positioned the operation cylinder part rotatably to the container body outer periphery can be employ | adopted preferably.

  The screw shaft is made of synthetic resin or the like. Further, it is formed separately from the operation handle, and is loosely fitted to the operation handle so as to be capable of relative vertical movement with a predetermined width and relative rotation with a predetermined width.

  The inner dish is made of synthetic resin or the like, and the inner periphery is screwed onto the outer periphery of the screw shaft, and the outer periphery is slidably fitted to the inner peripheral surface of the container and attached to the lower part of the container. . Then, it is mounted so as to be raised or lowered by the rotation of the screw shaft by the rotation of the operation handle. That is, the force against the frictional force of the threaded portion is configured to act on the peripheral edge, and the frictional force between the inner peripheral surface of the container and the outer peripheral edge of the intermediate dish acts sufficiently larger than the frictional force of the screwed portion, In addition, since the ascending force or descending force generated at the screwing portion is sufficiently larger than the frictional force between the inner circumferential surface of the container and the outer peripheral edge of the inner dish, the inner dish rises or lowers due to the rotation of the screw shaft.

  As a specific shape of the intermediate dish, a screw tube portion provided with a thread on the inner surface is provided on the inner peripheral edge portion, and a slide portion that is slidably fitted on the outer peripheral edge portion on the inner peripheral surface of the container is provided. And a sliding part connected by a bottom plate part. The screw provided in the screw tube portion is generally configured as a short screw line segment, but the screw on the outer periphery of the screw shaft is formed as a groove, and is formed as a protrusion that slides on the groove. Articles may be configured. In addition, the bottom plate portion may be a flat plate shape of a donut plate, but considering deformation caused by the rise of the screw shaft, deformation due to distraction is not so desirable, so there is a shape with room for deformation. Is preferably employed. For example, the thing of the form provided with the unevenness which raised or depressed one part is preferable.

  Further, since the inner plate is deformed as the screw shaft rises, it is preferable to provide an annular easily deformable portion on the bottom plate portion that can be easily deformed. The easily deformable portion can be formed, for example, by thinning the annular portion around the center portion of the bottom plate portion. Alternatively, an annular linear recess may be formed.

  In the present invention, the screw shaft is loosely fitted to the operation handle so as to be able to move up and down with a predetermined width and rotate with a predetermined width. Further, a conversion mechanism for converting the rotational movement of the operation handle and the lifting movement of the screw shaft is provided between the operation handle and the screw shaft. Then, when the operation handle is rotated, the screw shaft starts to rotate after a predetermined width rises with respect to the operation handle, and when the operation handle is released, the screw shaft is lowered by a predetermined width with respect to the operation handle due to the hydraulic pressure. It is configured to rotate by a predetermined width.

  By providing the conversion mechanism, it is possible to release the liquid pressure that has risen during the liquid discharge, and thus it is possible to prevent the liquid from leaking after the discharge operation is completed. That is, if the operation handle is rotated in the direction in which the inner plate is raised, the screw shaft is pushed upward by a predetermined width by the action of the initial conversion mechanism. At that time, the outer peripheral edge of the inner plate does not move due to the frictional force with the inner peripheral surface of the peripheral wall of the container body, and the bottom plate portion of the inner plate is elastically deformed. Next, when the rotation of the operation handle with respect to the screw shaft is completed, the screw shaft begins to rotate and the intermediate plate rises in a deformed state, and the liquid above the intermediate plate is discharged from the discharge hole. When the operation handle is released, the deformed inner pan is pressed by the hydraulic pressure, and the screw cylinder screwed to the intermediate pan is lowered by a predetermined width with respect to the operation handle, and the internal pressure is released. The operation handle rotates by a predetermined width in the reverse direction as the screw cylinder is relatively lowered.

  As a form of the conversion mechanism, a lower sliding surface that gradually lowers in a predetermined direction provided on the operation handle and an upper sliding surface that gradually lowers in a predetermined direction provided on the screw cylinder are arranged in the direction in which the operation handle is raised in the middle dish. It may be configured to slide by rotation and push up the upper sliding surface by the lower sliding surface to push the screw shaft upward. Each upper sliding surface and lower sliding surface may be provided along the center circle of the rotating shaft. The relative ascending width of the screw shaft may be appropriately selected depending on the size of the container body. For example, about 0.5 mm ± 0.3 mm is appropriate, but is not limited to this.

  As a configuration for restricting the relative rising width of the screw shaft, the screw shaft is loosely fitted to the above-described operation handle so as to be able to move up and down by a predetermined width and to rotate by a predetermined width. Therefore, this configuration is restricted at least within a range in which the lower sliding surface and the upper sliding surface slide relative to each other.

  The first means is configured as follows. That is, the container body A having the discharge hole 22 at the top and the inner peripheral surface having the same shape and the same size from the lower part to the upper part, and the rotation of the container body A from the outside of the container body A is rotatable. The operation handle B is provided so as to be operable, and the operation handle B with the screw shaft C standing in the container body A, the inner peripheral edge of the screw shaft C are screwed together, and the outer peripheral edge is slidable on the inner peripheral surface of the container body A. A container having a middle pan D fitted thereto, and configured so that the middle pan D is raised by the rotation of the screw shaft C by rotating the operation handle B. A conversion mechanism for converting the rotational movement of the operation handle B and the vertical movement of the screw shaft C is provided between the operation handle B and the screw shaft C. As the operating handle B rotates, the screw shaft C rises by a predetermined width with respect to the operating handle B. It rotates in after, worm shaft C hydraulically upon release of the operating handle B is composed as a predetermined width lowered with respect to the operating handle B.

  The second means is configured as follows. That is, in the first means, the bottom plate portion 52 of the inner tray D is provided with an annular easily deformable portion 54.

  The third means was configured as follows. That is, in the first means, the intermediate dish D is provided with a raised portion 52a in which the outer half of the bottom plate portion 52 is raised in an annular shape, and the bottom plate portion 52 on the inner side of the raised portion 52a has a thin easily deformable portion 54. It was.

The fourth means is configured as follows. That is, in any one of the first to third means, the upper sliding surface f ₂ that gradually lowers in a predetermined direction provided along the center circle on the lower surface of the screw shaft C, and the operation handle B. The upper sliding surface f _{2 on} the upper surface and the lower sliding surface f ₁ gradually descending in a predetermined direction provided at the opposed position constitute a conversion mechanism.

  In the container of the present invention, when the stored liquid is discharged, if the operation handle B is stopped and released, the internal pressure pushes down the screw shaft C via the intermediate dish D, so that the liquid leaks from the discharge hole 22 which is inconvenient. Can be prevented. In addition, since the operation only needs to release the rotational pressure of the operation handle B, it is not particularly difficult and can naturally prevent liquid leakage.

  Further, when the bottom plate portion 52 of the inner tray D includes the annular easily deformable portion 54, the inner tray D can be more easily deformed by the conversion mechanism, so that the internal mechanism operates smoothly and does not feel strange. Can be done.

  When the intermediate plate D is provided with a raised portion 52a in which the outer half of the bottom plate portion 52 is raised in an annular shape, and the bottom plate portion 52 inside the raised portion 52a is a thin easily deformable portion 54, the deformation by the conversion mechanism is caused. Since it is possible to perform without extending the intermediate dish D, it is possible to perform easier deformation, and the internal mechanism operates smoothly and an operation without a sense of incongruity can be performed.

An upper sliding surface f ₂ that gradually falls in a predetermined direction provided along the center circle on the lower surface of the screw shaft C, and a lower portion that gradually lowers in a predetermined direction provided at a position opposite to the upper sliding surface f _{2 on} the upper surface of the operation handle B. the case where the conversion mechanism with the sliding surface f ₁ is also pushed up screw shaft C, depressed even reasonably smoothly performed.

At a predetermined position on the lower surface of the fitting cylinder 44 is provided with a pair of upper projections 48 with the upper sliding face f ₂ to the central symmetrical positions on the lower surface.

The fitting tube 44 can be moved up and down at a predetermined interval until the engagement protrusion 45 of the fitting tube 44 comes into contact with the locking protrusion 32 of the support tube 33 protruding above the predetermined interval.
