  Between the outer peripheral surface of the elevating member 18 and the inner peripheral surface of the elevating member guide portion 26 of the main body 16, a rotation preventing portion 50 that prevents the elevating member 18 from rotating is formed.

  As shown in FIG. 7, the rotation prevention unit 50 includes one or more locking protrusions 54 that are provided on the outer circumferential surface of the elevating member 18 at equal intervals in the circumferential direction, and the elevating member guide unit 26. One or more locking grooves 52 are formed on the inner peripheral surface at intervals in the circumferential direction and into which the locking protrusions 54 are inserted. That is, when the elevating member 18 is inserted into the elevating member guide portion 26 of the main body 16, the engaging protrusion 54 is inserted into the engaging groove 52, and the elevating member 18 can move in the vertical direction. Rotation is prevented. Of course, when the cross-sectional shape of the elevating member 18 is a polygon such as a quadrangle, the elevating member 18 itself constitutes the rotation preventing unit 50. At this time, the inner peripheral surface of the elevating member guide portion 26 corresponding to the elevating member 18 is formed to correspond to the cross-sectional shape of the elevating member 18.

  The cover 20 is coupled to the outer peripheral surface of the elevating member guide portion 26 of the main body 16 and serves to protect the discharge passage 42 through which the contents of the elevating member 18 are discharged. A plurality of protrusions 62 are formed on the surface so that the user can easily grasp and rotate them by hand, and a locking rib 40 formed on the outer peripheral surface of the elevating member guide portion 26 is formed on the inner peripheral surface of the lower end thereof. A locking projection 64 is formed to be locked to the.

  Here, when the locking protrusion 64 of the cover 20 is locked to the locking rib 40 formed on the outer peripheral surface of the elevating member guide portion 26 and a predetermined force is applied in the upward direction, the locking rib 40.

  Also, a skirt portion 66 connected to the lower end of the cover 20 by a plurality of connecting members 66a that can be easily separated is formed to maintain the state fixed to the outer peripheral surface of the main body 16, and the cover 20 is When rotated with a predetermined force or more, the skirt portion 66 is separated from the cover 20, and the cover 20 is separated from the main body 16.

  An operation unit 70 is formed between the cover 20 and the elevating member 18 to raise or lower the elevating member 18 when the cover 20 is rotated in the forward direction or the reverse direction.

  The operating portion 70 is inserted into the elevating member 18 by projecting in a cylindrical shape from the upper side of the inner surface of the cover 20 to the lower side, and a female screw portion 72 formed on the upper inner peripheral surface of the elevating member 18. The support portion 76 and a male screw portion 74 formed on the outer peripheral surface of the support portion 76 and screwed into the female screw portion 72 are configured.

  Explaining the operation of the operating unit 70, the elevating member 18 is supported by the rotation preventing unit 50 so as not to rotate on the inner peripheral surface of the elevating member guide unit 26 of the main body 16. The cover 20 is in a state where the locking protrusion 64 is locked to a locking rib 40 formed on the outer peripheral surface of the main body 16, and the female screw portion 72 of the elevating member 18 and the male screw portion 74 of the cover 20. Since the cover 20 is rotated, when the cover 20 is rotated, the cover 20 is idly rotated on the outer peripheral surface of the main body 16, whereby the female screw portion 72 of the elevating member 18 is Ascending or descending along the male threaded portion 74.

  Although not shown in the drawing, the operating portion 70 is formed with a male screw portion on the upper side of the outer peripheral surface of the elevating member 18 and is screwed into the inner peripheral surface of the cover 20 corresponding to the male screw portion. A part can be formed and configured.

  Hereinafter, the operation of the container stopper according to the present invention configured as described above will be described.

  10 to 13 are operation state diagrams of the container stopper according to the first embodiment of the present invention.

  In a state where the container stopper is closed at the inlet 12 of the container, the upper surface of the inlet 12 of the container is in close contact with the outer portion of the seal member 32 mounted inside the main body 16 to seal the container 10, The opening / closing plate 44 of the elevating member 18 is in close contact with the inner portion of the seal member 32 and is in a sealed state. Therefore, the contents stored in the container 10 maintain a sealed state.

  In such a state, when the user discharges the contents stored in the container 10 to the outside, first, the cover 20 is rotated in the forward direction. Then, the skirt portion 66 is separated and the cover 20 is rotated while being separated from the main body 16. At this time, the cover 20 rotates idly because the locking protrusion 64 is locked to the locking rib 40 formed on the outer peripheral surface of the main body 16.

  As described above, when the cover 20 is rotated, the lifting member 18 is lowered by the operating portion 70 formed between the cover 20 and the lifting member 18, so that the opening / closing plate 44 of the lifting member 18 is The container 10 is opened by being separated from the seal member 32. That is, since the locking protrusion 54 of the elevating member 18 is inserted into the engaging groove 52 formed in the elevating member guide portion 26 of the main body 16 to prevent the rotation, the cover 20 rotates. Then, the female screw portion 72 formed on the elevating member 18 is released from the male screw portion 74 of the cover 20, and the elevating member 18 moves downward.

  In this manner, the elevating member 18 continues to descend, and the locking protrusions 38 formed on the inner peripheral surface of the elevating member 18 become the detachment preventing protrusions 36 formed on the inner peripheral surface of the elevating member guide portion 26. When the contact is made, the elevating member 18 is not lowered any further. As a result, when the cover 20 is further rotated, a force is applied to the cover 20 to move upward, and the engagement of the cover 20 is increased. The stop protrusion 64 is disengaged from the locking leave 40 formed on the main body 16. Next, when the container 10 is tilted after the cover 20 is removed from the main body 16, the contents stored in the container 10 flow into the discharge passage 42 through the inlet 46 of the elevating member 18, It is discharged from the discharge passage 42 to the outside.

  Here, a projecting portion 48 is formed at the end of the elevating member 18, and it is easy for a user to bite and elevate the elevating member 18. Further, when the contents are discharged through the discharge passage 42, since the external air flows into the container 10 from the gap 60 between the lifting member 18 and the lifting member guide portion 26, the contents are It is discharged more smoothly through the discharge passage 42.

  When the user tries to seal the container 10 again after discharging a predetermined amount of contents to the outside, if the cover 20 is put on the body 16 and then rotated in the opposite direction, the male thread portion of the cover 20 74 is fastened to the female screw portion 72 of the elevating member 18, and the elevating member 18 is raised. Then, the opening / closing plate 44 of the elevating member 18 is in close contact with the seal member 32 and the container 10 is sealed. When the cover 20 is further rotated, the opening / closing plate 44 comes into close contact with the seal member 32, and the elevating member 18 cannot be raised any further, and the cover 20 is relatively lowered. That is, since the elevating member 18 cannot be raised any further, when the female screw portion 72 of the elevating member 18 is tightened to the male screw portion 74 of the cover 20, the cover 20 is lowered and the locking projection 64 of the cover 20 is moved. The main body 16 is locked over the locking leave 40 of the main body 16.

  14 to 17 are operation state diagrams of the container stopper according to the second embodiment of the present invention, and FIG. 18 is a sectional view taken along line BB in FIG.

  On the other hand, in the container stopper according to the present invention, when the user discharges the contents stored in the container with the cover 20 removed, the elevating member 18 needs to maintain the lowered state. In such a case, the elevating member 18 is maintained in the raised state so that the contents stored in the container do not leak to the outside.

  Therefore, the container stopper according to the second embodiment of the present invention has a locking maintenance protrusion that maintains the locking state of the lifting member guide portion 26 of the first embodiment with the locking protrusion 38 formed on the lifting member 18. 37 is further formed. When the lifting / lowering member 18 moves to the uppermost side, the locking maintaining projection 37 is locked with a locking projection 38 formed on the lifting / lowering member 18, so that the outer portion of the seal member 32 is brought into the inlet of the container. 12, the inner portion is in close contact with the elevating member 18 and seals the container 10. Of course, the locking state of the locking protrusion 38 and the locking maintaining protrusion 37 is such that the locking state is released when the user applies a force exceeding a predetermined level.

  On the other hand, the locking projection 38 needs to move to the lower side of the separation preventing projection 36 to maintain the descending state of the elevating member 18, and it is necessary to prevent the elevating member 18 from further descending. . Accordingly, a second locking protrusion 39 can be further formed on the lifting member 18 above the locking protrusion 28.

  The second locking projections 39 are arranged so that the locking projections 28 are not lowered further after the locking projections 28 pass through the separation preventing projections 36 and move to the lower side of the separation preventing projections 36. The elevating member 18 is formed on the outer peripheral surface of the elevating member 18 so that the elevating member 18 is not lowered further while maintaining the engaged state with the engagement maintaining projection 37 when passing the separation preventing projection 36.

  On the other hand, when the main body 16 is coupled to the container 10, the elevating member guide portion 26 of the main body 16 pushes the elevating member 18 due to the generation of a bending moment, thereby obstructing the movement of the elevating member 18. There was a problem that there was.

  Accordingly, at least one of the locking protrusion 38 and the second locking protrusion 39 is formed of a flexible material, or protrudes outward along the outer peripheral surface of the elevating member 18 as shown in FIG. The plurality of protrusions 39a can be configured. Since the locking protrusion 38 and the second locking protrusion 39 are composed of the plurality of protrusions 39a, when the body 16 is coupled to the container 10, the body 16 is moved up and down by the generation of a bending moment. Even if the member guide portion 26 pushes the elevating member 18, it can move more smoothly in the vertical direction.

  On the other hand, the separation preventing projection 36 and the locking maintaining projection 37 can also be composed of a plurality of projections protruding inward along the inner peripheral surface of the elevating member guide portion 26.

  The container stopper according to the second embodiment of the present invention configured as described above operates similarly to the first embodiment. However, in the state where the elevating member 18 is completely lowered, the locking projection 38 passes through the separation preventing projection 36 so that the locking projection 38 and the separation preventing projection 36 maintain the locked state, and The second locking protrusion 39 and the locking maintaining protrusion 37 maintain the locked state. Therefore, when the elevating member 18 remains fixed and the container 10 is tilted, the contents stored in the container 10 flow into the discharge passage 42 through the inlet 46 of the elevating member 18. , And is discharged from the discharge passage 42 to the outside.

  On the other hand, the lifting member 18 seals or opens the container 10 by being pulled out or pushed by a user's hand or mouth even when the cover 20 is removed.

  In particular, when the elevating member 18 is pulled out to the uppermost side, the locking projection 28 passes through the locking maintenance projection 37 and maintains the locking state with the locking maintenance projection 37, thereby The movement of the elevating member 18 is limited. Therefore, even when the cover 20 is removed, the elevating member 18 is fixed and the container 10 is kept in a sealed state.
