Movement is possible but rotation is prevented. Of course, when the cross-sectional shape of the elevating member 18 has a polygonal shape such as a quadrangle, the elevating member 18 itself constitutes an anti-rotating part 50. At this time, the inner circumferential surface of the elevating member guide part 26 corresponding to the elevating member 18 is formed corresponding to the cross-sectional shape of the elevating member 18.

The cover 20 is coupled to the outer circumferential surface of the elevating member guide part 26 of the main body 16 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 outer circumferential surface of the 20 so as to be easily rotated by the user by hand, and the lower inner circumferential surface of the lower surface of the lower surface is caught by a locking rib 40 formed on the outer circumferential surface of the elevating member guide part 26. 64 is formed.

Here, the locking jaw 64 of the cover 20 is separated from the locking rib 40 when a predetermined force is applied upward in a state of being caught by the locking rib 40 formed on the outer circumferential surface of the elevating member guide part 26. It has a structure that can be.

In addition, the cover 20 has a skirt portion 66 connected to a plurality of connecting members 66a which can be easily dropped at the bottom thereof to maintain a fixed state on the outer circumferential surface of the main body 16 and to cover the cover 20. The cover 20 is detached from the main body 16 while the skirt portion 66 is torn off when the rotation is performed by a predetermined force or more.

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

The operation part 70 is a female screw portion 72 formed on the upper inner peripheral surface of the elevating member 18, and protrudes in a cylindrical form from the upper side of the cover 20 to the lower side of the elevating member 18 It consists of a support portion 76 inserted therein and a male screw portion 74 formed on the outer circumferential surface of the support portion 76 and screwed to the female screw portion 72.

Looking at the operation of the operation unit 70, the elevating member 18 is supported on the inner circumferential surface of the elevating member guide portion 26 of the main body 16 so as not to rotate by the anti-rotation unit 50 The cover 20 is in a state where the locking jaw 64 is engaged with the locking rib 40 formed on the outer circumferential surface of the main body 16, and the female screw portion 72 and the cover 20 of the elevating member 18 are closed. Since the screw 20 is in a screw-joined state, when the cover 20 is rotated, the cover 20 idles on the outer circumferential surface of the main body 16 and accordingly, the female screw part of the elevating member 18 72 is raised or lowered along the male threaded portion 74 of the cover 20.

On the other hand, although not shown, the operating part 70 is a male screw portion is formed on the upper side of the outer peripheral surface of the elevating member 18, the inner threaded surface of the cover 20 corresponding to the male screw portion screwed to the female threaded portion Can be formed.

The operation of the container closure according to the present invention configured as described above will be described below.

10 to 13 is a view showing the operation of the container cap according to the present invention.

When the container cap is closed at the container inlet 12, the upper surface of the container inlet 12 is in close contact with the outer portion of the sealing member 32 mounted inside the main body 16 to seal the container 10. The opening and closing plate 44 of the elevating member 18 is in close contact with the inner portion of the sealing member 32 to be sealed. Thus, the contents stored in the container 10 remain sealed.

In this state, when the user discharges the contents stored in the container to the outside, first, the cover 20 is rotated in the forward direction. Then, the cover 20 is rotated while being separated from the main body 16 while the skirt portion 66 is torn off. In this case, the cover 20 is idling because the locking jaw 64 is locked to the locking rib 40 formed on the outer circumferential surface of the main body 16.

As such, when the cover 20 is rotated, the opening and closing plate of the elevating member 18 is lowered while the elevating member 18 is lowered by the operation unit 70 formed between the cover 20 and the elevating member 18. 44 disengages from the sealing member 32 to open the container 10. That is, since the locking protrusion 54 of the elevating member 18 is inserted into the locking groove 52 formed on the elevating member guide portion 26 of the main body 16 and the rotation is prevented, the cover 20 is closed. When rotated, 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 is moved downward.

As such, when the elevating member 18 continuously descends and the engaging projection 38 formed on the inner circumferential surface of the elevating member 18 contacts the release stop 36 formed on the inner circumferential surface of the elevating member guide portion 26, the elevating member 18 is no longer lowered, and thus, when the cover 20 is further rotated, a force to move upward is applied to the cover 20 and the locking jaw 64 of the cover 20 is applied. It is separated from the locking ribs 40 formed in the main body 16. Then, the cover 20 is peeled off from the main body 16 and the container 10 is tilted, and 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 to the outside through the discharge passage 42.

Here, a protrusion 48 is formed at the end of the elevating member 18 so that the user can easily suck and suck the elevating member 18. When the contents are discharged through the discharge passage 42, the external air is introduced into the container 10 through the gap 60 between the lifting member 18 and the lifting member guide part 26. The discharge passage 42 can be better discharged.

When the user wants to seal the container 10 again after discharging a certain amount of contents to the outside, when the cover 20 is covered with the main body 16 and rotated in the opposite direction, the male screw part of the cover 20 As the member 74 is tightened to the female screw portion 72 of the elevating member 18, the elevating member 18 is lifted. Then, the opening and closing plate 44 of the elevating member 18 is in close contact with the sealing member 32 to seal the container 10. Further, when the cover 20 is further rotated, the opening and closing plate 44 is brought into close contact with the sealing member 32 so that the lifting member 18 can no longer be lifted, so that the cover 20 is relatively Will descend. That is, when the female screw portion 72 of the elevating member 18 is tightened to the male screw portion 74 of the cover 20 because the elevating member 18 is no longer raised, the cover 20 is lowered and the cover 20 is lowered. The locking jaw 64 of the 20 is caught over the locking rib 40 of the main body 16.

14 to 17 are operation state diagrams of the container cap according to the second embodiment of the present invention, Figure 18 is a cross-sectional view of the B-B line in FIG.

On the other hand, the container stopper according to the present invention, when the user discharges the contents stored in the container to the outside while the cover 20 is removed, the elevating member 18 needs to maintain the lowered state, otherwise the elevating member ( 18, it is necessary to maintain the elevated state so that the contents stored in the container do not leak to the outside.

Therefore, in the container stopper according to the second embodiment of the present invention, the elevating member guide part 26 in the first embodiment has a locking projection 38 which is formed in the elevating member 18 and the engaging retaining jaw to maintain the locked state ( 37) is further formed. When the lifting retaining member 37 moves to the uppermost side, the locking retaining jaw 37 has the outer side of the sealing member 32 due to the locking protrusion 38 formed on the lifting member 18. 12) is in close contact with the inner portion of the elevating member 18 is in close contact with the container 10. Of course, the locking state of the locking projection 38 and the locking holding jaw 37 is such that the locking state is released when the user applies a predetermined force or more.

On the other hand, it is necessary to maintain the lowered state of the elevating member 18 by moving the locking projection 38 to the lower side of the separation prevention projection 36, it is necessary to prevent the elevating member 18 from descending any more. Therefore, the lifting member 18 may be further formed with a second locking projection 39 on the upper side of the locking projection 28.

The second locking projection 39 is a locking projection 28 is passed through the separation prevention jaw (36) to move to the lower side of the departure prevention jaw 36 after the locking projection 28 is no longer falling off so as not to fall further. When passing through it is formed on the outer circumferential surface of the elevating member 18 so that the elevating member 18 is no longer lowered by maintaining the locked state on the latch holding jaw (37).

Meanwhile, when the main body 16 is coupled to the container 10, the lifting member guide part 26 of the main body 16 presses the lifting member 18 by the generation of the bending moment to move the lifting member 18. There is a problem that can interfere.

Accordingly, at least one of the locking protrusions 38 and the second locking protrusions 39 may have a flexible material, or as illustrated in FIG. 18, a plurality of protrusions protruding outwardly along the outer circumferential surface of the elevating member 18. It may be composed of protrusions 39a. The locking projection 38 and the second locking projection 39 are composed of a plurality of projections 39a, so that the main body 16 is generated by the generation of a bending moment when the main body 16 is coupled to the container 10. Even if the elevating member guide portion 26 of the elevating member 18 is able to move up and down more smoothly.

On the other hand, the separation prevention jaw 36 and the locking retaining jaw 37 may also be composed of a plurality of protrusions protruding inward along the inner circumferential surface of the elevating member guide portion 26.

The container closure according to the second embodiment of the present invention having the configuration as described above operates similarly to the first embodiment. However, in the state in which the elevating member 18 is completely lowered, the locking projection 38 passes through the separation prevention jaw 36 to maintain the locking projection 38 and the separation prevention jaw 36, and at the same time, the second locking stone The machine 39 is to maintain the locking state with the locking holding jaw 37. Thus, the elevating member 18 is maintained in a fixed state, and when the container 10 is tilted, the contents stored in the container 10 are introduced into the discharge passage 42 through the inlet 46 of the elevating member 18. It is discharged to the outside through the discharge passage 42.

Meanwhile, the elevating member 18 seals or opens the container 10 by being drawn or pressed by the user's hand or mouth even when the cover 20 is removed.

In particular, when the lifting member 18 is drawn to the uppermost side, the locking projection 28 passes through the locking holding jaw 37 to maintain a locking state with the locking holding jaw 37 to move the lifting member 18. Will be limited. Therefore, even when the cover 20 is removed, the elevating member 18 is fixed, thereby keeping the container in a closed state.
