  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 a liquid discharge container equipped with a raising mechanism for the middle dish as described above, the outer peripheral edge of the middle dish is fitted to the inner circumferential surface of the container so as to be liquid-tightly slidable. Although obtained, since the inner peripheral edge of the inner plate is screwed to the screw shaft, it cannot be denied that the sealing performance of that portion is inferior to that of the outer peripheral edge. This type of container generally accommodates a liquid with a high viscosity, so that it can be used even when the sealing performance is slightly inferior. However, the viscosity may change due to a change in temperature or the like, and more sufficient countermeasures are required.

  The present invention has been made in view of the above-described points, and further improves the sealing performance of the inner peripheral edge of the inner dish, can be improved without deteriorating the operation function, is easy to handle, and has a structure. We propose a container with a simple raising mechanism for the inner pan.

  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, elastomer, or the like, and is erected at the center of the container body, and is rotated by the rotation of the operation handle to move the inner plate up and down. The screw shaft may be formed integrally with the operation handle, or may be formed separately and fixed by appropriate means such as fitting, fusing, and adhesion.

  The inner pan is made of synthetic resin or elastomer, and the inner periphery is screwed to 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. ing. 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 inner dish, a cylindrical portion provided with a thread on the inner peripheral surface is provided on the inner peripheral edge, a sliding portion that is slidably fitted on the outer peripheral surface of the container is provided, and a screw is provided. The thing of the form which connected the cylinder part and the sliding part with the baseplate part is employ | adopted. In addition, when fins are formed on the inner plate, it can be sufficiently effective to be formed from a general synthetic resin that forms this type of intermediate plate, such as a polyolefin-based resin. Or it is good to comprise all by a soft material formation part and to form a fin in the part. The soft material forming portion may be formed of an elastomer such as synthetic rubber.

Between the upper side surface of the female thread 50 continuous with the lower side surface of the male thread 42 and between the bottom part 50b between the threaded threads of the female thread 50 continuous with the upper part 42t of the male thread. It is formed.

Therefore, when projecting the fin only on the male thread, the unit fin projecting from the top of the thread of the male thread through the lower side to the bottom between the thread adjacent to the bottom, A plurality of male threads are arranged at intervals from the lower end to the upper end. The lower end portion where the unit fin is provided is provided at a position where it is screwed with the female screw of the intermediate plate at the lowest position. Further, the interval between the unit fins is preferably an interval at which the outer edge of the next unit fin comes into contact with the female thread before the contact between the outer edge of one unit fin and the female thread is released. Each unit fin needs to have a size that closes the gap in close contact with the outer surface of the female thread facing the outer edge.

  In addition, when projecting a fin only on the female thread, a unit fin projecting from the top of the thread of the female thread through the upper side to the bottom between the thread adjacent to the upper side, Provide at least one location. In this case, at least one place is sufficient, but the strength is required because the fin covers from the start to the end of container use. Therefore, it is preferable to provide a plurality of unit fins, and it is preferable that the thickness of each unit fin is relatively large.

  Further, when the fins are projected from both the male thread and the female thread, it is preferable that the fins provided on the female thread get over the fins provided on the male thread. The thickness of the fin provided on the female thread is made sufficiently thicker than the thickness of the fin provided on the male thread, and the fin provided on the male thread is It is preferable that the end edge is separated from the male thread and can be swung.

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.

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

  1 to 4 show a container (hereinafter simply referred to as a container) provided with the raising mechanism of the middle dish of the present invention, and 1 in the figure shows the container. The container 1 includes a container body A, an operation handle B, a screw shaft C, and an inner dish D.

The container body A is made of a synthetic resin, and is composed of a body portion forming member A ₁ and a top portion forming member A ₂ , and the body portion forming member A ₁ has a window hole 2 formed at the center. A cylindrical peripheral wall 4 is erected from the periphery of the bottom wall 3. A locking cylinder 5 is erected on the upper surface of the peripheral wall 4. A central portion of the bottom wall 3 is provided with a recessed portion 3a that is recessed in an annular shape in order to obtain a space for mounting the operation handle B, and a plurality of kerfs are vertically provided at equal intervals in the circumferential direction on the inner peripheral edge portion. ing.

The top forming member A ₂ has a top wall 21 extending from the upper end of the fitting tube 20 that is fitted on the outer periphery of the locking tube 5 while preventing protrusions from engaging with each other, and a discharge hole is formed in the center of the top wall 21. 22 is drilled. A seal cylinder 23 suspended from the peripheral edge of the top wall 21 is fitted in a liquid-tight manner to the inner periphery of the locking cylinder 5.

  The operation handle B stands up with an operation cylinder 31 shorter than the outer peripheral edge of the substrate 30 that is rotatably mounted on the back surface of the container body A, and a locking protrusion 32 is provided on the inner periphery at the center of the substrate 30. The support cylinder 33 is erected. Further, a support column 34 is erected at the center of the support tube 33 so as to protrude upward from the support tube 33, and a plurality of locking ribs 35 are protruded radially from the outer surface of the support column 34.

  The screw shaft C includes a connecting portion 41 at the lower end portion of the hollow rod-shaped main body 40, and a male screw 42 is provided around the outer periphery of the main body 40. The connecting portion 41 includes a substrate portion 43 in which the main body 40 is erected from the center of the upper surface, and a fitting cylinder 44 that is suspended from the lower surface of the substrate portion 43. Engagement ridges 45 are provided on the lower outer periphery of the fitting tube 44, and a plurality of circumferential engagement ribs 46 are provided radially on the inner periphery. Then, the engagement protrusion 45 is moved over the lower surface of the engagement protrusion 32 to prevent the engagement protrusion 45 from coming out upward, and the engagement ribs 46 are fitted between the engagement ribs 35 of the operation handle B so that mutual engagement is achieved. The fitting cylinder 44 is fitted to the inner periphery of the support cylinder 33 by preventing the rotation, and the upper end of the column 34 is fitted to the lower end inside the main body 40 so as to integrate both, and the substrate part 43 is integrated with the bottom of the container body. The wall 3 is rotatably contacted with the upper surface of the inner peripheral edge to prevent the wall 3 from coming out downward.

The inner plate D is mounted by fitting a female thread 50 provided on the inner peripheral edge portion with a male thread 42 of the screw shaft C, and slidably fitting the outer peripheral edge to the inner peripheral surface of the container body A. ing. Also the body portion D ₁ is constitutes a part of the inner peripheral edge portion at a low density synthetic rubber soft material forming part D ₂ formed of, other portions are formed of polypropylene. Body portion D ₁ is the bottom plate portion 54 outwardly from the upper edge of the inner cylindrical portion 53 is extended, and connects the sliding portion 55 on the outer peripheral edge of the bottom plate portion 54. The inner cylinder portion 53 forms an upper portion in the enlarged diameter portion 53a which is expanded outwardly to secure the soft material forming part D _2, also, the outer peripheral edge of the bottom plate portion 54 through the vertical wall portion 54 Level down. A female thread 50 protrudes from the inner surface of the inner cylindrical portion 53 immediately below the enlarged diameter portion 53a. None the fixed ring by a suitable fixing means fusion or adhesion or the like in the soft material forming unit D ₂ is within an annular recess formed in the inner diameter portion 53a, a female screw thread 50 of the inner cylindrical portion on the inner peripheral surface The female thread 50 of the soft material forming portion that is continuous with the protrusion is provided in a projecting manner. The term “continuous” in this case does not necessarily mean that the screw threads are continuous with each other, but a state in which the screw thread 42 can be screwed with the male thread 42 of the screw shaft C, and both are in a separated state.

  The female thread 50 of the intermediate plate D is integrally provided with a fin F that closes and vertically cuts the gap d between the male thread 42 and the female thread 50 that are screwed together. As shown in an enlarged view in FIG. 2, the fin F is a unit fin f projecting from the top 50t of the thread 50 of the female thread 50 to the bottom 50b between the screw thread passing through the upper surface and adjacent to the top. As shown in FIG. 4, 8 are provided continuously at 90 ° apart positions, and the fins F are formed by these.

  In the container 1 configured as described above, since the fin F is always present between the male thread 42 and the female thread 50, the ambient temperature surrounding the container rises during storage and the fluidity of the stored liquid increases. However, the liquid can be prevented from moving downward from the threaded portion. Further, when the operating handle B is rotated from the state shown in FIG. 1, the screw shaft C rotates, and the male screw 42 of the screw shaft C and the female screw 50 of the intermediate plate D act to move the intermediate plate D upward. Then, the stored item above the middle dish D is discharged from the discharge hole 22. At this time, since the gap F between the male thread 42 and the female thread 50 is closed by the fin F, the liquid in the portion is scraped up by the fin F and does not move downward.

  FIGS. 5 to 7 show other examples. In the example of FIG. 1, instead of forming the fins F on the inner plate D, the fins F are formed on the screw shaft C. FIG. Therefore, the inner tray is integrally formed without the soft material forming portion. In this example, as shown in FIG. 6, unit fins f projecting from the top part 42t of the thread 42 of the male thread 42 to the bottom part 42b passing through the lower side and adjacent to the thread part below, As shown in FIG. 7, the fins F are configured by being arranged from the lower end portion to the upper end portion of the male thread 42 continuously at 90 ° apart positions. The other configuration is the same as that of the example of FIG.

  Similarly, in this case, even if the fluidity of the stored liquid increases during storage, the presence of the fins F can prevent the liquid from moving downward from the liquid screwing portion. Further, when the operation handle B is rotated from the state of FIG. 5, the screw shaft C rotates, and the male screw 42 of the screw shaft C and the female screw 50 of the intermediate plate D act to move the intermediate plate D upward. Then, the stored item above the middle dish D is discharged from the discharge hole 22.
