Here, an inflow opening 46 through which contents stored in the container 10 flow into the discharge passage 42 is formed at a lower portion of the lift member 18 in the circumferential direction when the lift member 18 moves downward.

The protrusion unit 48 may be formed on the upper end of the lifting member 18 along the circumferential direction so that the user can easily bite the outer surface of the lifting member 18 with teeth or lips, and form the hooking protrusion 38 on the outer surface of the middle portion of the lifting member 18 , the hooking protrusion 38 is hooked with the separation preventing protrusion 36 formed on the inner surface of the lifting member guide unit 26 .

Here, the hooking between the hooking protrusion 38 and the separation preventing protrusion 36 prevents the lifting member 18 from being disengaged downward from the main body 16 and limits the moving distance of the lifting member 18 .

A gap 60 through which air can pass is formed between the lifting member 18 and the lifting member guide unit 26. , the contents can be easily discharged without intermittent flow.

Meanwhile, as shown in FIGS. 8 and 9 , a reinforcing rib 55 for structurally reinforcing a part of the inflow opening 46 may be integrally formed on the inner surface of the lifting member 18 . The reinforcing rib 55 may be formed at a predetermined height from the lower end of the lifting member 18 , especially higher than the inflow opening 46 , and may have various shapes such as a "-" shape, a "+" shape, and the like.

An anti-rotation unit 50 for preventing rotation of the lifting member 18 is formed between an outer surface of the lifting member 18 and an inner surface of the lifting member guide unit 26 of the main body 16 .

As shown in FIG. 7 , the anti-rotation unit 50 is composed of at least one hooking protrusion 54 formed on the outer surface of the lifting member 18, and the hooking protrusion is lifted from the lifting member 18 at regular intervals along the circumferential direction of the lifting member 18. The outer surface of the member 18 protrudes; and at least one hooking groove 52 each inserted with a respective hooking rib 54 is formed on the inner surface of the lifting member guide unit 26 at regular intervals along the circumferential direction. In other words, when the lifting member 18 is inserted into the lifting member guide unit 26 of the main body 16, since the hooking protrusion 54 is inserted into the hooking groove 52, the lifting member 18 can move in the upward and downward directions, but is prevented from The lifting member 18 rotates. If the cross-sectional shape of the lifting member 18 is polygonal, such as a rectangle, the shape of the lifting member 18 itself can serve as the anti-rotation unit 50 . Here, the inner surface of the elevating member guide unit 26 corresponds to the elevating member 18 and has a shape corresponding to the cross-sectional shape of the elevating member 18 .

The cover 20 combined with the outer surface of the lifting member guide unit 26 of the main body 16 plays a role of protecting the discharge channel 42 of the lifting member 18 for discharging contents, and a plurality of protrusions are formed on the outer surface of the cover 20 so that the user can The cover 20 is easily grasped and turned by hand, and a hooking protrusion 64 is formed on the inner surface of the lower part of the cover 20, and the hooking protrusion 64 corresponds to the hooking rib 40 formed on the outer surface of the lifting member guide unit 26. hook up.

Here, the hooking protrusion 64 of the cover has the following structure: in the hooked state where the hooking protrusion 64 is hooked with the hooking rib 40 , when a predetermined upward force is applied to the hooking protrusion 64 , the hooking protrusion 64 is disengaged from the hooking rib 40 formed on the outer surface of the lifting member guide unit 64 .

Formed on the lower end of the cover 20 is a skirt unit 66 for fixing the cover 20 to the outer surface of the main body 16, which is connected with the cover 20 by a plurality of connection members 66a which can be easily separated from the cover 20 when the cover is closed. When the 20 is rotated by more than a predetermined rotational force, the skirt unit 66 is separated from the cover 20 and then the cover 20 is separated from the main body 16 .

Between the cover 20 and the lifting member 18 is formed an operation unit 70 for moving the lifting member 18 upward or downward according to rotation of the cover 20 in a normal direction or a reverse direction.

The operation unit 70 includes the following parts: a female screw unit 72 formed on the inner surface of the upper part of the lifting member 18; a support unit 76 inserted in the lifting member 18, and the supporting unit 76 is lifted from the upper part of the cover 20 in a cylindrical shape. and a male screw unit 74 formed on an outer surface of a support unit 76 and combined with the female screw unit 72 .

The operation of this operation unit 70 is: Since the anti-rotation unit 50 supports the lifting member 18 and prevents it from rotating on the inner surface of the lifting member guide unit 26 of the main body 16, the hooking protrusion 64 of the cover 20 is formed on the outer surface of the main body 16. The hooking rib 40 on the top is hooked, and the female thread unit 72 of the lifting member 18 and the male thread unit 74 of the cover 70 are screwed to each other; when the cover 20 rotates, the cover 20 idles on the outer surface of the main body 16, and Idle rotation of the cover 20 moves the female screw unit 72 of the lifting member 18 upward or downward along the male screw unit 74 of the cover 20 .

Meanwhile, although not shown in the drawings, the operation unit 70 may be composed of a male screw unit formed on the outer surface of the lifting member 18 and a male screw unit formed on the inner surface of the cover 20 to be threaded with the corresponding male screw unit. Combined female thread unit.

The operation of the container closure device according to the invention will be described below.

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

When the container closing device closes the inlet 12 of the container, the sealing member 32 closely contacts the upper surface of the inlet 12 of the container 10 outside the container 10, and the sealing member 32 closely contacts the switch plate 44 of the lifting member 18 inside the lifting member. , thereby sealing the container 10 . Therefore, the container 10 storing the contents is kept in a sealed state.

From the above-mentioned state, when the user discharges the contents stored in the container, first, the cap 20 is rotated in the forward direction. Then, the skirt unit 66 is separated, and the cover 20 is turned in a state of being separated from the main body 16 . Here, since the hooking protrusion 64 is hooked with the hooking rib 40 formed on the outer surface of the main body 16, the cover 20 performs idle rotation.

In this way, when the cover 20 is rotated, since the lift member 18 is lowered by the operation unit 70 formed between the cover 20 and the lift member 18 , the switch plate 44 is separated from the sealing member 32 so that the container 10 is opened. In other words, since the lifting member 18 is prevented from rotating due to the hooking protrusion 54 of the lifting member 18 being inserted into the hooking groove 52 formed at the lifting member guide unit 26 of the main body 16, when the cover 20 is rotated, the lifting member 18 is formed. The female thread unit 72 of the cover 20 is loosened from the male thread unit 74 of the cover 20, and then the lifting member 18 moves downward.

In this way, the elevating member 18 descends continuously, stops descending when the hooking protrusion 38 formed on the inner surface of the elevating member 18 contacts the separation preventing protrusion 36 formed on the inner surface of the elevating member guide unit 26, and then , when the cover 20 is further rotated, a force is applied to move the cover 20 relatively upward, so that the hooking protrusion 64 of the cover 20 is separated from the hooking rib 40 formed in the main body 16 . Then, when the container 10 is tilted after the lid 20 is removed from the main body 16 , the contents stored in the container 10 flow into the discharge passage 42 through the inflow opening 46 of the lift member 18 and are discharged through the discharge passage 42 .

Here, since the end of the lifting member 18 is formed with the protrusion 48 , the user can easily bite and suck the lifting member 18 . Since external air flows into the interior of the container 10 through the gap 60 between the lift member 18 and the lift member guide unit 26 when the contents are discharged through the discharge passage 42 , the contents can be more easily discharged through the discharge passage 42 .

If the user wishes to reseal the container 10 after discharging a predetermined amount of content, after the cap 20 is capped on the main body 16, by turning the cap 20 in the reverse direction, the male thread unit 74 of the cap 20 is fastened to that of the lifting member 18. The female screw unit 72, and the lifting member 18 rises. The switch plate 44 then comes into close contact with the sealing member 32 , thereby sealing the container 10 . If the cover 20 is further rotated, since the switch plate 44 is in close contact with the sealing member 32, the lifting member 18 can no longer rise, and the cover 20 is relatively lowered. In other words, since the lifting member 18 does not rise further, if the female screw unit 72 of the lifting member 18 is fastened to the male screw unit 74, the cover 20 descends and the hooking protrusion 64 goes over the hooking rib 40 of the main body 16 and engages with the hooking rib 40 of the main body 16. The hook.

14 to 17 are state views showing the operation of the container closing device according to the second embodiment of the present invention, and Fig. 18 is a sectional view showing the container closing device along line B-B in Fig. 14 .

At this time, if the user wishes to discharge the contents stored in the container, the container closure device according to the present invention needs to be kept in the descending state of the lifting member 18, and the rising state of the lifting member 18 makes the contents stored in the container Can't leak out.

Therefore, according to the second embodiment of the present invention, the lifting member guide unit 26 of the container closing device in the first embodiment is further formed with a hook holding protrusion 37 for holding the lifting member guiding unit 26 and formed on the lifting member 18. The hooking state between the hooking protrusions 38. When the lifting member 18 reaches the highest portion, the hook holding protrusion 37 is hooked with the hooking protrusion 38, and the outside of the sealing member 32 closely contacts the inlet 12 of the container 10, and the inside of the sealing member 32 closely contacts the lifting member 18 , thereby sealing the container 10 . When the user applies a force greater than a predetermined amount, the hooked state between the hooking protrusion 38 and the hooking holding protrusion 37 can be disengaged.

At this time, it is necessary to maintain the lowered state of the lifting member 18 achieved by the downward movement of the hooking protrusion 38 from the separation preventing protrusion 36 and to prevent the lifting member 18 from further lowering. Therefore, above the hooking protrusion 28 , a second hooking protrusion 39 may be further formed on the lifting member 18 .

The second hooking protrusion 39 is formed on the outer surface of the lifting member 18 so as to prevent the hooking protrusion 28 from further descending after going over the separation prevention protrusion 36 and moving below the separation prevention protrusion 36; At 36 o'clock, the lifting member 18 is prevented from descending by maintaining the hooked state with the hooking holding protrusion 37 .

At this time, the lifting member 18 is pressed by the lifting member guide unit 26 of the main body 16 due to the bending moment applied by the connection between the main body 16 and the container 10, so there is a problem that the movement of the lifting member 18 may be interfered.

Therefore, at least one of the hooking protrusion 38 and the second hooking protrusion 39 may be made of a flexible material, or, as shown in FIG. Although the lifting member 18 is pressed by the lifting member guide unit 26 of the main body 16 due to the bending moment applied by the connection between the main body 16 and the container 10, the plurality of protrusions of the hooking protrusion 38 and the second hooking protrusion 39 39a, the lifting member 18 can move up and down more easily.

Meanwhile, the separation preventing protrusion 36 and the hook holding protrusion 37 may also be constituted by a plurality of protrusions protruding inward from the inner surface of the elevating member guide unit 26 .

The container closure device according to the second embodiment of the present invention having the above structure can be operated in a similar manner to the container closure device according to the first embodiment. But when the lifting member 18 finishes descending, the hooking protrusion 38 keeps hooking with the anti-separation protrusion 36 after passing over the anti-separation protrusion 36 , and meanwhile, the second hooking protrusion 39 keeps hooking with the hooking protrusion 37 . Thus, the lift member 18 remains fixed, and when the container 10 is tilted, the contents stored in the container 10 flow into the discharge channel 42 through the inflow opening 46 of the lift member 18 and are discharged through the discharge channel 42 .

At this time, if the cover 20 is removed, the lifting member 18 can also be pulled or pushed by the user's hand or mouth, so that the container 10 can be sealed or opened.

Specifically, when the lifting member 18 is pulled to the highest position, the hooking protrusion 28 restricts the movement of the lifting member 18 by passing over the hooking holding protrusion 37 and maintaining a state of being hooked with the hooking holding protrusion 37 . Thus, the seal of the container is maintained by securing the lifting member 18 despite the removal of the lid 20 .
