Description

  The present invention relates to a container having a raising mechanism for a middle dish.

  There has been proposed a container configured to have a raising mechanism for raising a middle dish in a container, and raising the middle dish by the operation of the raising mechanism to raise the liquid contained thereabove. (For example, see Patent Document 1)

  The container described in Patent Document 1 includes an operation handle that can be operated from the outside of the container body, and a middle dish that has an inner peripheral edge screwed to a screw shaft of an operation handle that is erected in the container body. The screw shaft is rotated by the movement, and the inner plate is raised. When the inner peripheral edge of the container body is circular, there is a possibility that the inner tray also rotates together with the rotation of the screw shaft, and there is a possibility that the contents are not smoothly poured out. Accordingly, the force against the frictional force of the screwing portion is configured to act on the peripheral portion, and for example, the force is configured to be larger than the frictional force of the screwing portion within a range in which the frictional force of the outer peripheral edge can slide.

  In order to prevent such mutual rotation and raise the intermediate dish smoothly, means such as considering the contact area of the outer peripheral part of the intermediate dish with the inner peripheral surface of the container can be considered. Yes, there was still room for improvement.

  In consideration of such points, a concave groove is provided vertically on the inner surface of the peripheral wall of the container body, and on the other hand, a protrusion that fits in the concave groove so as to move up and down is provided on the outer periphery of the inner plate. A container has also been proposed that prevents the relative rotation of the dish and enables smooth raising of the inner dish.

JP 2008-206723 A

  However, in the latter case, there is a problem in the sealing performance in the container body, and when the contents are liquid, there is a possibility that the liquid leaks from the fitting portion between the groove and the protrusion.

  The present invention has been made in view of the above-described points, and is a container provided with a lifting mechanism that lifts a middle dish that is fitted in the container body so as to be able to ascend, between the outer circumference of the middle dish and the inner circumference of the container. There is proposed a container provided with a raising mechanism of a middle dish that is capable of raising the middle dish smoothly with a simple structure without causing a liquid leak.

The first means is configured as follows. That is, a container body A having a circular inner peripheral surface of the same size from the lower part to the upper part,
An operation handle C provided at the bottom of the container body A so as to be relatively rotatable with respect to the container body A and capable of being operated from the outside, and having a screw shaft 41 standing in the container body A;
The inner periphery is screwed to the screw shaft 41, and the outer periphery is liquid- tight and slidably fitted to the inner peripheral surface of the container body A.
The container is configured such that the middle plate E is raised by the rotation of the screw shaft 41 by the relative rotation of the operation handle C with respect to the container body A, and the liquid stored above the middle plate E is pushed up.
Below the sliding part with the inner peripheral part of the container body A on the outer periphery of the intermediate dish E, an elastomer rotation preventing projection 61 that presses the outer peripheral edge to the inner peripheral part of the container body A is fixed .
The rotation preventing protrusions 61 are a plurality of rotation preventing protrusions 61 having the same configuration and protruding at equal intervals in the circumferential direction.

The second means is configured as follows. That is, in the first means , the rotation preventing projection 61 is integrally projected from the fitting cylinder 60 fixed to the outer periphery of the inner tray E by insert molding.

The third means was configured as follows. That is, in the first means , the rotation preventing projection 61 is provided on the outer periphery of the inner tray E with the base end fixed by insert molding.

The fourth means is configured as follows. That is, in any one of the first to third means , the rotation preventing projection 61 is slidable on the inner peripheral portion of the container body A with the rotation preventing projection 61 tilted in a predetermined direction. Welded.

The fifth means is configured as follows. That is, in any one of the first to fourth means , the outer periphery of the intermediate plate E below the rotation preventing projection 61 is fitted to the inner periphery of the container body A so as to be slidable. An annular stable rising protrusion 56 was provided.

The sixth means is configured as follows. That is, in any one of the first to fifth means, the upper end of the screw shaft 41 is rotatably fitted to the back surface of the inner lid B fitted to the upper end of the container body A.

The seventh means is configured as follows. That is, in any one of the first to sixth means, a rotation restricting means for restricting the mutual rotation in a predetermined direction is provided between the container body A and the operation handle C. Yes.

  According to the present invention, since the container body A has a circular inner peripheral surface of the same size from the lower part to the upper part, the inner peripheral surface of the container body A and the inner periphery of the container body A are not provided with a concave groove on the peripheral surface of the container body. There is no risk of liquid leaking downward from the sliding portion, and the anti-rotation projection 61 does not slide without contacting the liquid, so it does not slip and therefore rotates. The presence of the preventing protrusion 61 can reliably prevent the inner tray E from rotating relative to the container body A, and the inner tray E can be raised smoothly.

  When a plurality of rotation preventing projections 61 having the same shape are provided at equal intervals in the circumferential direction, the sliding frictional force is evenly applied to the outer surface of the inner plate E, and the inner plate E can be raised more smoothly. Become.

  When the rotation preventing projection 61 is integrally protruded from the fitting tube 60 fixed to the outer periphery of the inner plate E by insert molding, the fixed rotation preventing projection 61 is firmly fixed and fixed inside. Inconveniences such as detachment from the plate E can be prevented more reliably, and since it is insert molding, there is also an advantage that it can be projected at an accurate position.

  When the protrusion 61 for preventing rotation is provided on the outer periphery of the inner plate E with the base end fixed by insert molding, the protrusion 61 for preventing rotation similarly protrudes to the correct position of the inner plate E. There is an advantage that can be established.

  When the rotation preventing projection 61 is slidably pressed against the inner peripheral portion of the container body A with the rotation preventing projection 61 tilted in a predetermined direction, the rotation preventing projection 61 rotates without contacting the liquid. The anti-motion function can be exerted so that it does not slip, and the inner plate E tilts in the direction in which it will rotate together with the screw shaft 41 due to the rotation of the screw shaft 41 and is elastically pressed. For this reason, the drag in the direction that would be rotated acts greatly to prevent the rotation.

  When an annular stable rising protrusion 56 is provided on the outer periphery of the intermediate plate E below the rotation preventing protrusion 61 so as to be slidably raised on the inner periphery of the container body A, It is possible to more reliably prevent rattling and the like when rising, and further smooth rising is possible.

  When the upper end of the screw shaft 41 is pivotably fitted to the back surface of the inner lid B fitted to the upper end of the container body A, the rotation of the screw shaft 41 is eliminated and a smooth inner plate E is also removed from this point. There is also an advantage that the sealing performance of the screwed portion between the screw shaft and the intermediate plate E can be more reliably performed.

  In the case where a rotation restricting means for restricting mutual rotation in a predetermined direction is provided between the container body A and the operation handle C, the inconvenience of rotating the operation handle C in the reverse direction can be reliably prevented.

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

  FIGS. 1 to 3 show an example of a container (hereinafter simply referred to as a container) provided with a raising mechanism for a middle dish, and 1 in the figure indicates the container. The container 1 includes a container body A, an inner lid B, an operation handle C, a screw shaft member D, an inner dish E, a protrusion forming member F, and a cap G.

  The container body A has a mouth and neck portion 11 that is reduced in diameter in three stages of a cylindrical lower stage 11a, a middle stage 11b, and an upper stage 11c, respectively, at the upper end portion of the cylindrical peripheral wall 10. A thread is provided on the outer periphery of the middle stage 11b, and a locking protrusion is provided on the outer periphery of the upper stage 11c. An annular recess 12 is formed on the outer periphery of the lower end of the container body peripheral wall 10 so that the operation handle C can be pivotably fitted, and a locking ridge protrudes from the upper part of the container body peripheral wall 10 in the annular recess 12. Has been established.

  In addition, a locking protrusion 13 for providing a rotation restricting means for the operation handle C is provided at a position opposite to the lower end of the container body peripheral wall 10. The locking projection 13 is formed with one side surface in the circumferential direction as an inclined surface and the other side surface as a vertical surface, and sequentially gets over and engages with an engagement projection described later. The rotation restricting means for the operation handle C will be described later.

  The inner lid B is prevented from coming off due to the overhanging engagement between the protrusions on the outer peripheral upper end portion of the mouth-and-neck portion 11, the fitting cylinder 20 is fitted, and the top plate 21 extending from the upper end edge of the fitting cylinder 20 This closes the upper end opening of the mouth and neck portion 11. A cylindrical portion 22 is suspended from the center of the back surface of the top plate 21, and a plurality of circumferentially engaging ribs 23 are projected from the upper end of the outer periphery of the cylindrical portion 22. A spout 24 is formed. Further, a seal cylinder suspended from the lower surface of the top plate 21 is liquid-tightly fitted to the inner periphery of the upper stage 11c of the mouth-neck portion 11.

  The operation handle C is pivoted so as to be fitted into the annular recess 12 of the container body A so as to be capable of mutual rotation with the peripheral wall 10 of the container body and to be pulled out downward by overriding engagement of the protrusions. A fixed cylinder 32 is provided for fixing the screw shaft member D from the upper surface of a bottom plate 31 provided with a cylindrical portion 30 and extending from the lower end of the rotating cylindrical portion 30. On the outer periphery of the fixed cylinder 32, a large number of longitudinal ribs are provided in the circumferential direction.

  The screw shaft member D has a screw shaft 41 standing upright from a fitting base portion 40 fitted to the operation handle C. A screw thread is provided around the outer periphery of the screw shaft 41. The fitting base portion 40 includes a peripheral wall portion 40a fitted to the outer periphery of the fixed cylinder 32 of the operation handle C. The peripheral wall portion 40a is engaged with a plurality of vertical ribs provided in the circumferential direction on the inner peripheral surface with a plurality of vertical ribs provided on the outer periphery of the fixed cylinder 32 so as to prevent mutual rotation. . Further, the outer peripheral edge of the flange portion 40b extending outward from the lower end edge of the peripheral wall portion 40a is fitted to the inner peripheral lower end portion of the rotating cylinder portion 30 so as not to be pulled out upward. The prevention of slipping out is performed by getting over and engaging with the lower surface of the ridge projecting on the inner periphery of the rotating cylinder part 30. Further, the screw shaft 41 is erected from the inner peripheral edge of the flange-shaped top wall portion 40c extending from the upper end of the peripheral wall portion 40a, and the upper end of the screw shaft 41 is rotatably fitted to the outer periphery of the cylindrical portion 22 of the inner lid B. ing. Therefore, the operation handle C and the screw shaft member D are configured to move integrally.

  Engagement protrusions 42 project from the upper surface of the flange 40b at equal intervals in the circumferential direction. One side surface of the engagement protrusion 42 in the circumferential direction is a vertical surface and the other side surface is an inclined surface. The engagement protrusion 42 and the locking protrusion 13 constitute a rotation restricting means for restricting the mutual rotation in a predetermined direction between the container body A and the operation handle C. When the operation handle C is rotated in a predetermined direction with respect to the container body A, the inclined surfaces of the engaging protrusion 42 and the locking protrusion 13 can come into contact with each other, and can be overcome each other. The vertical surfaces of the engaging protrusion 42 and the locking protrusion 13 are engaged so that mutual rotation in that direction is impossible.

  As shown in FIGS. 2 and 3, the intermediate dish E has a configuration in which an inner peripheral wall 50 and an outer peripheral wall 51 are connected by a top wall 52, and the top wall 52 is inclined from the upper edge of the inner peripheral wall 50. After rising, the curve is lowered and the outer peripheral edge is connected to the upper edge of the outer peripheral wall 51. In addition, a concave portion in which the top wall 52 is depressed downward is formed in a cross shape in plan view. On the inner surface of the inner peripheral wall 50, a thread that is screwed with the thread on the outer periphery of the screw shaft 41 is provided. The screwed portion is screwed with sufficient liquid tightness. A support plate 53 is spanned between the inner peripheral wall 50 and the outer peripheral wall 51, and a plurality of the support plates 53 are spanned in the circumferential direction. Further, the lower portion of the outer peripheral wall 51 is formed in a large diameter portion 51a, and an annular seal protrusion 54 is projected from the upper end portion of the large diameter portion 51a.

  The protrusion forming member F is formed of an elastomer containing natural rubber, synthetic rubber, or the like, and is provided for providing the rotation preventing protrusion 61 on the inner tray E. The protrusion forming member F includes a rotation preventing protrusion 61 and a fitting cylinder 60. In this case, the protrusion forming member F has a fitting cylinder 60 embedded and fixed to the large diameter part 51a below the seal protrusion 54 by insert molding, and a pair of rotation preventing protrusions are provided at positions opposite to the fitting cylinder 60. The part 61 protrudes integrally. As shown in FIG. 3, the rotation-preventing projection 61 is inclined and projected in a predetermined direction that would rotate, that is, has a cross-sectional shape that is curved or inclined in a predetermined direction. A pair is provided at opposing positions. In addition, the predetermined direction which will rotate shows the direction which will rotate with the screw shaft 41 temporarily by rotation of the screw shaft 41.

  The form of the rotation preventing projection 61 is not limited to the one described above. For example, as shown in FIGS. 6 and 7, a fitting cylinder embedded and fixed to the large diameter portion 51a below the seal projection 54 by insert molding. It may be configured as a rotation preventing projection 61 having three projections spaced apart from each other by a predetermined distance from 60, or may have other configurations, and is formed of an elastomer and has an outer peripheral edge as the peripheral wall 10 of the container body. Any structure that slides on the inner peripheral surface may be used.

  Further, the projecting portions of the rotation preventing projection 61 are not limited to the two locations described above, but may be one location or a plurality of locations. It is preferable to provide a plurality of rotation preventing protrusions 61 at equal intervals in the circumferential direction. In this case, the same configuration means that the rotation preventing projection 61 constituted by a single projection as shown in FIG. 3 is also used for the rotation preventing projection 61 constituted by a plurality of projections as shown in FIG. Each case is also considered as one form.

  Furthermore, a stable raising protrusion 56 is provided at the lower end of the large-diameter portion 51a below the rotation preventing protrusion 61 so as to make the rising of the intermediate dish E more stable. As shown in FIG. 1, the inner plate E has an inner periphery screwed onto the outer periphery of the screw shaft 41, and the outer peripheral seal protrusion 54, the rotation prevention protrusion 61, and the stability raising protrusion 56 are respectively connected to the inner periphery of the peripheral wall 10. The seal projection 54 is mainly involved in providing liquid-tightness, the rotation prevention projection 61 mainly contributes to mutual rotation prevention, and the stability raising projection 56 is mainly used. Contributes to prevention of rattling when rising.

  The cap G is shaped like a flat plate with the top wall extending from the upper end of the peripheral wall screwed to the middle step 11b of the mouth and neck portion 11, and is detachably attached to the container body A.

  In the container 1 configured as described above, when the cap G is removed from the state shown in FIG. 1 and the operation handle C is rotated relative to the container body A, the screw shaft member D rotates together with the operation handle C. In this case, the screw shaft 41 rotates integrally, and the intermediate plate E rises accordingly, and the liquid stored in the container body A above the intermediate plate E is pushed out from the spout 24 and can be used. When the intermediate plate E is raised by the rotation of the screw shaft 41, the presence of the rotation preventing projection 61 reliably prevents the disadvantage that the intermediate plate E rotates together with the screw shaft 41 and does not rise. .

FIG. 4 shows another example. In the example of FIG. 1, an application body H is provided on the inner lid B. The structure of the inner lid B is basically similar to the example of FIG. 1, and in this example, the support cylinder portion 25 is erected from the peripheral edge of the top surface of the top plate 21, and the cylinder 22 is penetrated through the top plate 21 to support cylinders. The upper end protrudes to a position above the portion 25, and the cylinder 27 is erected on the outer periphery of the cylinder portion 22 via a rib 26. The application body H includes a hollow columnar application portion 80 made of a porous material such as a synthetic resin foam, the inner periphery of the application portion 80 is fitted to the outer periphery of the cylinder 27, and the application portion 80 A fixing frame 81 in which a fitting cylinder is suspended from a flange fitted to the outer periphery of the fixing cylinder 81 is fitted into the outer periphery of the support cylinder portion 25 while preventing the fitting cylinder 81 from coming out. The cap G has a shape that can accommodate the application body H in accordance with the shape of the application body H, and is detachably attached to the container body A. Other configurations are the same as those in the example of FIG.

  In this case, the liquid in the container A can be applied through the application part 80 of the application body H.

  FIG. 5 shows still another example. In the example of FIG. 1, a spatula for extending the coating solution is provided on the inner lid B. The structure of the inner lid B is basically similar to the example of FIG. 1. In this example, the cylindrical portion 22 passes through the top plate 21 and rises to the upper side, and the supporting cylindrical portion 25 is raised on the outer periphery thereof. The portion 25 and the cylindrical portion 22 are connected by a rib 26. Further, a spatula member I is fitted on the outer periphery of the support cylinder portion 25. The spatula member I has a plate-like spatula portion 90 whose tip is inclined obliquely at the upper end of the fitting tube portion fitted on the outer periphery of the support tube portion 25, and a spout 91 is opened in the spatula portion 90. ing. And it is comprised so that it may pass between the support cylinder part 25 and the cylinder part 22 from the inside of the container body A, and may connect to the spout 91. Further, a rod plug 70 that is fitted to the spout 91 from the back surface of the top wall 52 of the cap G is suspended. Other configurations are the same as those in the example of FIG.

  As in each of the above examples, various forms of the discharge part of the container can be employed, and the present invention is not limited to these. The material of each member is not particularly limited, but a synthetic resin or the like can be preferably used as the material. In each of the above examples, the rotation preventing projection 61 is fixed to the intermediate plate E by insert molding, but the rotation preventing projection 61 is fixed to the intermediate plate E by fitting. You may do it.
