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.

JP 2008-206723 A

  In such a container, there is a possibility that excess liquid may be discharged even after the middle dish is stopped due to the residual pressure in the container body after the middle dish is raised.

  The present invention has been made in view of the above points, and is a container provided with a lifting mechanism that raises the middle dish fitted in the container body, and there is a risk that excess liquid may come out after the middle dish stops. In contrast, the present invention proposes an excellent container that has the effect of drawing back the liquid in the vicinity of the spout slightly into the container body and that prevents the operation handle from returning to the container body.

  The first means is configured as follows. That is, a container body A having an inner peripheral surface of the same shape and the same size from the lower part to the upper part, and a bottom part of the container body A are provided so as to be relatively rotatable with respect to the container body A and to be operable from the outside. In addition, an operation handle C in which the screw shaft 41 is erected in the container body A, and an inner tray E in which the inner peripheral edge is screwed to the screw shaft 41 and the outer peripheral edge is fitted to the inner peripheral surface of the container body A are provided. 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 stored liquid above the middle plate E is pushed up. The rotation restricting means is provided between the pair of elastic engagement pieces 13 that are provided with locking protrusions 13b and that can swing up and down, and the locking protrusions 13b are engaged with each other. In addition, the engaging protrusions 42 are annularly arranged at equal intervals, and one engaging protrusion 13b is adjacent to the adjacent engaging protrusion 42. While being locked to the end face side, the other locking protrusion 13b is locked to one end face side of the adjacent engaging protrusion 42 to maintain a stable state. The rotation is restricted in a predetermined direction, and the operation handle C is pressed in the direction opposite to the predetermined direction when the other locking protrusion 13b gets over the engaging protrusion 42 while being elastically pressed.

  The second means is configured as follows. In other words, in the first means, the ride-over surface f1, which is the circumferential end surface of the engaging projection 13b, can be overridden by the ride-over surface f3, which is the other circumferential surface of the engagement projection 42. Then, the pressed surface f2 that is one end surface in the circumferential direction of the engaging projection 42 is formed by the pressing surface f4 that is the other circumferential end surface of the locking projection 13b or the pressing edge 16 that is the engaging projection side edge of the other end surface. It was configured to be pressable.

  The third means was configured as follows. That is, in the second means, the overpassing surface f1 and the overpassing surface f3 are gently inclined surfaces, the pressing surface f4 is a steeply inclined surface, and the pressing edge 16 is a vertical edge of the engaging projection side edge. Yes, the pressed surface f2 is a steeply inclined surface.

  The fourth means is configured as follows. In other words, in the first means, the ride-over surface f3 which is the other circumferential surface of the engagement protrusion 42 can be overridden by the ride-over surface f1 which is one circumferential surface of the locking projection 13b. The pressed edge 43, which is the locking projection side edge of the circumferential end surface of the engaging projection 42, is configured to be pressed by the pressing surface f4, which is the other circumferential end surface of the locking projection 13b.

  The fifth means is configured as follows. That is, in the fourth means, the overpassing surface f1 and the overpassing surface f3 are gently inclined surfaces, the pressing surface f4 is a steeply inclined surface, and the pressed edge 43 is a vertical projection side edge of the vertical surface. It is.

  The sixth means is configured as follows. That is, in any one of the first to fifth means, each elastic engagement piece 13 is projected from one end surface in the circumferential direction of the notch 14 formed in the lower end of the peripheral wall 10 of the container body. The oscillating plate portion 13a and the locking projection 13b suspended from the lower surface of the oscillating plate portion 13a.

  The seventh means is configured as follows. That is, in the sixth means, each elastic engagement piece 13 has the tip of the connecting portion 13c protruding from the tip of the swing plate portion 13a with the easily cut portion 15 at the other circumferential end of the notch portion 14. Connected through.

  The eighth means is configured as follows. That is, in any one of the first to seventh 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.

  According to the present invention, the rotation restricting means having a special configuration is provided between the container body A and the operation handle C, and the rotation restriction means controls the mutual rotation of the container body A and the operation handle C. Since the operation handle C is restricted in a predetermined direction, it is possible to prevent the operation handle C from returning backward with respect to the container body A, and to prevent the intermediate tray E that has once been raised from being lowered.

  Further, the rotation restricting means is configured so that a pressing force in a direction opposite to a predetermined direction is applied to the operation handle C when the other locking projection 13b gets over the engagement projection 42 while being elastically pressed. Each time the protrusion 13b gets over and engages the engaging protrusion 42, it also has an advantage that a back suction effect can be exhibited. Furthermore, in order to maintain the stable state because the other locking projection 13b is locked to the one end surface side of the adjacent engagement projection 42, the container body A and the operation handle C are It becomes a stable state, and both can reliably prevent inconveniences such as rattling in the rotating direction.

  The ride-over surface f1, which is one end surface in the circumferential direction of the locking projection 13b, is configured to allow the ride-over surface f3, which is the other circumferential surface of the engagement projection 42, to be crossed. When the pressed surface f2 that is one end surface in the circumferential direction of the engaging projection 42 is configured to be pressed by the pressing surface f4 that is the end surface or the pressing edge 16 that is the side edge of the engaging projection on the other end surface, In addition to exerting a suction effect, there are advantages that the structure is simple and the manufacture is easy.

  The overpassing surface f1 and the overpassing surface f3 are gently inclined surfaces, the pressing surface f4 is a steeply inclined surface, the pressing edge 16 is an engaging projection side edge of a vertical surface, and the pressed surface f2 is a steeply inclined surface. In some cases, the presence of the vertical surface can prevent reverse rotation more effectively. In this case, the structure is simple and an efficient back suction effect is exhibited.

  The ride-over surface f1 that is one end surface in the circumferential direction of the locking projection 13b is configured to allow the ride-over surface f3 that is the other end surface in the circumferential direction of the engagement projection 42 to be crossed. In the case where the pressed edge 43 which is the locking projection side edge of the circumferential end surface of the engagement projection 42 is configured to be pressed by the pressing surface f4 which is the end surface, the back suction effect is similarly exhibited. There is an advantage that the structure is simple and the manufacture is easy.

  When the riding-over surface f1 and the riding-over surface f3 are gently inclined surfaces, the pressing surface f4 is a steeply inclined surface, and the pressed edge 43 is a vertical projection locking side edge, the vertical direction is the same as above. The presence of the surface makes it possible to prevent the reverse rotation more effectively, and the structure is simple and exhibits an efficient back suction effect as described above.

  Each elastic engagement piece 13 is protruded from one end surface in the circumferential direction of the notch portion 14 formed in the lower end portion of the container body peripheral wall 10, and the latch is suspended from the lower surface of the swing plate portion 13a. When configured with the protrusion 13b, since the elastic engagement piece 13 can be protected in the cutout portion 14, the elastic engagement piece 13 is attached before assembly compared to the case where it protrudes downward from the lower surface of the container body. There is an advantage that inconveniences such as damage can be prevented.

  Each elastic engagement piece 13 is elastically engaged when the tip of the connecting portion 13c protruding from the tip of the swinging plate portion 13a is connected to the other circumferential end surface of the notch portion 14 via the easy cutting portion 15. Since the piece 13 is incorporated in the container peripheral wall 10, it is possible to more reliably prevent inconveniences such as the elastic engagement piece 13 being damaged by being damaged before assembly or before opening.

  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.

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. In addition, although a pair of rotation preventing projections 55 are provided at opposing positions, the present invention is not limited to this, and there may be one or a plurality of locations. For example, it is preferable to provide a plurality at equal intervals in the circumferential direction.

  Furthermore, a stable raising protrusion 56 is provided at the lower end of the large-diameter portion 51a below the rotation preventing protrusion 55 so as to make the rising of the intermediate plate E more stable.

Contributes to prevention of rattling when rising.

  The cap F 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 present invention, the rotation restricting means is provided between the container body A and the operation handle C. The rotation restricting means includes a pair of vertically movable elastic engaging pieces projecting locking protrusions, and engaging engagement with the locking protrusions, and being annularly arranged at equal intervals. Consists of protrusions. The mutual rotation of the container body A and the operation handle C is restricted in a predetermined direction. Also, one locking protrusion is locked to the other end surface side of the adjacent engaging protrusion, and the other locking protrusion is locked to one end surface side of the adjacent engaging protrusion so that the stable state Is maintained, the mutual rotation of the container body A and the operation handle C is restricted in a predetermined direction, and the operation handle C is fixed to the operation handle C when the other locking protrusion passes over the engagement protrusion while elastically contacting the engagement protrusion. It is configured so that a pressing force in the direction opposite to the direction is applied. Here, the predetermined direction refers to a mutual rotation direction for raising the intermediate plate E, for example, the container body A is rotated in a clockwise direction in a plan view, and the operation handle C is rotated in a counterclockwise direction in a plan view. When the middle dish E rises, the direction of each other is referred to as a predetermined direction.

  As shown in an enlarged view in FIG. 4, the elastic engagement piece 13 in this example protrudes in a notch portion 14 provided at a predetermined position on the lower end portion of the container body peripheral wall 10 so as to be swingable up and down. The elastic engagement piece 13 includes a swing plate portion 13a that protrudes from one end surface in the circumferential direction of the cutout portion 14 so as to be swingable up and down, a locking protrusion 13b that is suspended from the tip end portion of the swing plate portion 13a, The swing plate portion 13a is provided with a connecting portion 13c that protrudes from the tip end and is connected to the other end surface in the circumferential direction of the cutout portion 14 via an easy cut portion 15.

  The locking projection 13b is formed with one end surface in the circumferential direction as a gently inclined surface and the other end surface as a vertical surface. The gently inclined surface is used as a climbing surface f1, and the engaging projection side edge of the vertical surface is used as a pressing edge 16. It is composed.

  The engaging projections 42 are provided on the upper surface of the flange portion 40b of the screw shaft member D at regular intervals in the circumferential direction. Each engaging projection 42 has one circumferential end surface as a steeply inclined surface, and the other in the circumferential direction. The steeply inclined surface is formed as the pressed surface f2 and the gently inclined surface is configured as the overpassing surface f3.

In addition, one locking projection 13b and the other locking projection 13b are provided at substantially opposite positions, and as shown in a development view in FIG. 5, one locking projection 13b (left side in the figure) is provided. While being locked to the other end surface side of the adjacent engaging protrusion 42, the other locking protrusion 13b (right side in the figure) is locked to one end surface side of the adjacent engaging protrusion 42 and is in a stable state. To maintain. In other words, the ride-over surface f1 of one locking projection 13b is in contact with the to- be-ridden surface f3 of the adjacent locking projection 13b, and the pressing projection 16 of the other locking projection 13b is adjacent to the locking projection. It is locked to the lower edge of the pressed surface f2 of 13b and maintains a stable state.

In the container 1 configured as described above, when the cap F 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 so that 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 55 reliably prevents the disadvantage that the intermediate plate E rotates together with the screw shaft 41 and does not rise. .

  When the operation handle C is relatively rotated with respect to the container body A, each elastic engagement piece 13 is fixed by the easy-to-cut portion 15 at first. The overpass surface f1 of the stop projection 13b slides and rises on the overpass surface f3 of the engagement projection 42, and the easy-cut portion 15 is broken, and the other (right side in the figure) locking projection 13b is delayed. After the abutment surpassing surface f1 comes into contact with the overfitting surface f3 of the locking projection 13b, the sliding rise similarly occurs, and then, as shown in FIG. 6, one locking projection 13b (the left side in the figure) is engaged. After overcoming the protrusion 42 while being elastically pressed, the other locking protrusion 13b (right side in the figure) is positioned on the upper surface of the engaging protrusion 42, and then one locking protrusion 13b (left in the figure). The other locking projection 13b (on the right in the figure) is not connected to the upper surface of the engagement projection 42 even in a state in which the crossover surface f1 of the other) is in contact with the ride-over surface f3 of the left engagement projection 42. Then the pressing edge 16 is pressed When sliding down the surface f2, the pressed surface f2 is pressed, and at that time, the engaging protrusion 42 abutted by one of the locking protrusions 13b (left side in the figure) receives a reverse force, and accordingly As a result, the middle plate E slightly lowers and exhibits a back suction effect.

  The form of the locking projection 13b and the engagement projection 42 is not limited to the above example. For example, as shown in FIG. 7, one end surface in the circumferential direction of the locking projection 13b is a gently inclined surface and the other end surface is abrupt. It may be formed as an inclined surface, the gently inclined surface may be used as a climbing surface f1, and the steeply inclined surface may be configured as a pressing surface f4 that slides and presses the pressed surface f2. Further, as shown in FIG. 8, one end surface in the circumferential direction of the locking projection 13b is formed as a gently inclined surface, the other end surface is formed as a steeply inclined surface, the gently inclined surface is used as a climbing surface f1, and the steeply inclined surface is used as a pressing surface f4. In addition, one end surface in the circumferential direction of the engaging protrusion 42 is formed as a vertical surface and a gently inclined surface at the other end surface in the circumferential direction, the upper edge of the vertical surface is used as the pressed edge 43, and the gently inclined surface is formed. Each of the overpassed surfaces f3 may be configured. In these examples, the other configurations are the same as those in the example of FIG.

  FIG. 9 shows another example. In the example of FIG. 1, an application body G 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 and the support cylinder The upper end protrudes up to a position above the portion 25, and a cylinder 27 is erected on the outer periphery of the cylinder portion 22 via a rib 26. The applicator G includes a hollow cylindrical applicator 70 made of a porous material such as a synthetic resin foam, the inner periphery of the applicator 70 is fitted to the outer periphery of the cylinder 27, and the applicator 70 A fixed frame 71 is provided with a fitting cylinder suspended from a flange fitted to the outer periphery of the support cylinder portion 25, and the fitting cylinder is fitted to the outer periphery of the support cylinder portion 25 so as not to come out. The cap F has a shape that can accommodate the application body G in accordance with the shape of the application body G, 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 70 of the application body G.

  FIG. 10 shows still another example. In the example of FIG. 1, a spatula for extending the coating liquid 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 H is fitted on the outer periphery of the support cylinder portion 25. The spatula member H has a plate-like spatula part 80 whose tip is inclined obliquely at the upper end of the fitting cylinder part fitted to the outer periphery of the support cylinder part 25, and opens a spout 81 in the spatula part 80. ing. And it is comprised so that it may pass between the support cylinder part 25 and the cylinder part 22 from the container body A, and may connect to the spout 81. Further, a rod plug 60 that fits into the spout 81 from the back surface of the top wall 52 of the cap F is provided vertically. 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.
