Description:

TECHNICAL FIELD

The present invention relates to a closure of a vessel, and more particularly to a closure of a vessel, in which the closure of the vessel is sanitarily clean and is convenient for use because touching a discharging passage discharging contents stored in the vessel by hand is unnecessary, and sealing the entrance of the vessel is unnecessary.

BACKGROUND ART

FIG. 1 is a sectional view showing the closure of the vessel in accordance with the conventional art.

The closure of the vessel having conventional opening structure, is comprised of a main body 3 detachably coupled with an entrance of the vessel 1 which is sealed by a sealing member 2, an elevation member 4 installed in an outer upper portion of the main body 3, which is linearly moved up and down, and a cover 5 for covering the upper portion of the main body 3.

When a user drinks beverage stored in the vessel, the main body 3 of the conventional closure of the vessel having the above described structure, is separated from the beverage vessel 1, and then the sealing member 2 sealing the entrance of the vessel 1 is removed. And when the elevation member 4 is gripped and pulled upward by hand after the main body 3 is again coupled with the entrance of the vessel 1, and the cover 5 is opened, the upper surface 4′ of the elevation member 4 is separated from the head portion 3′ of the main body of the closure, and the entrance of the beverage vessel 1 is opened, so that a user may drink the beverage by tilting and discharging the beverage vessel 1.

When drinking the beverage is unnecessary, a user presses the elevation member 4 by hand, and make the elevation returned to the original position and the entrance of the vessel 1 sealed.

But the conventional closure of the vessel as described in the above, has the problem that it is inconvenient for use because the sealing member 2 which is fixed to the entrance of the vessel and seals the entrance of the vessel, is removed by hand, or by using additional apparatus such as a knife, etc. after the main body 3 is separated from the vessel 1, in order to open the vessel.

In particular, there is a trouble that a user should remove the sealing member 2 again, and the conventional closure of the vessel has the sanitary problem since it is difficult to remove the sealing member 2 from the rim because the sealing member 2 is adhered to the rim of the entrance of the vessel when the sealing member 2 is removed by hands.

The conventional closure of the vessel also has the problem that the closure of the vessel is not sanitarily clean because a discharging portion discharging beverage may be soiled since a user should open the entrance of the vessel by pulling the elevation member 4 upward by hand in order to drink the beverage, and the user should make the elevation member 4 moved to the original position again by pushing the elevation member 4 by hand after drinking beverage.

Hereinafter, the closure of the vessel according to the present invention will be explained with reference to the embodiments and the attached drawings in detail.

FIG. 1 is a sectional view showing the closure of the vessel in accordance with the conventional art, FIG. 2 is a prospective view showing the closure of the vessel in accordance with the first embodiment of the present invention, FIG. 3 is a prospective view showing the closure of the vessel the cover of which is removed in FIG. 2, FIG. 4 is a prospective view showing the closure of the vessel in FIG. 2 further formed with a reinforcing rib in the main body, FIG. 5 is a disassembled prospective view showing the closure of the vessel in FIG. 2, FIG. 6 is a sectional view showing the closure of the vessel in FIG. 2, FIG. 7 is a sectional view showing the closure of the vessel in A-A line in FIG. 6, and FIGS. 8 and 9 are a cross sectional view and a longitudinal view showing the closure of the vessel in FIG. 2 further formed with a reinforcing rib in the inside thereof.

The closure of the vessel in accordance with the present invention, is comprised of a main body 16 coupled to an entrance 12 of the vessel 10 which discharges contents stored in the vessel 10, an elevation member 18 forming a discharging passage discharging contents stored in the vessel 10, the elevation member 18 being inserted into the main body 16, moved up or down in the main body 16, and sealing or opening the entrance 12 of the vessel 10, and a cover 20 detachably coupled with the upper portion of the main body 16, the cover 20 moving the elevation member 18 up or down by being rotated in a positive direction or a negative direction and protecting a entrance portion of the elevation member 18, the entrance portion discharging the contents.

The main body 16 is comprised of a coupling unit 24 detachably coupled to the entrance 12 of the vessel 10 and formed in a cylindrical shape, and an elevation member guide unit 26 extended upwards from the coupling unit 24, and inserted with the elevation member 18, in which the elevation member 18 is moved up or down, the elevation member guide unit 26 having a diameter less than that of the coupling unit 24.

A plurality of protrusions 22 are formed at an outer surface of the coupling unit 24 in a predetermined interval, so that the coupling unit 24 may be easily gripped and rotated by user s hand, and a female screw unit 28 is formed in an inner surface of the coupling unit 24 coupled with a male screw unit 30 formed in the outer surface of the entrance 12 of the vessel 10.

Any connection method for detachably connecting the closure of the vessel with the entrance 12 of the vessel 10 between the closure of the vessel and the entrance 12 of the vessel 10 may be selected besides a connection of the female screw unit 28 and the male screw unit 30.

Meanwhile, there is a problem that the movement of the elevation member 18 may be interfered with because the elevation member 18 is pressed by the elevation 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 vessel 10. Therefore, at least one reinforcing rib 23 may be further formed in an outer surface of the main body 16 in a longitudinal direction, as shown in FIG. 4, in order to lessen the bending moment applied by the connection between the main body 16 and the vessel 10.

In addition, the reinforcing rib 13 may be formed in the main body 16, together with at least one reinforcing rib 23a having a center concentric to that of the elevation member guide unit 26.

A sealing member 32 is mounted on an upper portion of the coupling unit 24 in a circumferential direction, and closely contacted with an upper surface of the entrance 12 of the vessel 10. The sealing member 32 is a disc opened in a center portion thereof, and closely contacted with the upper surface of the entrance 12 of the vessel 10 when the coupling unit 24 of the main body 16 is coupled with the entrance 12 of the vessel 10, and thereby the contents stored in the vessel 10 is sealed.

As described in the above, the present invention may remove the inconvenience that the sealing member should be removed from the entrance 12 of the vessel 10, because the sealing member 32 is positioned in the inside of the closure of the vessel and additional sealing member for sealing the entrance 12 is unnecessary.

Herein, the sealing member 32 is closely contacted with the entrance 12 of the vessel 10 in the outer portion thereof and closely contacted with the elevation member 18 in the inner portion thereof, and thereby seals the vessel 10.

The elevation member guide unit 26 having a diameter less than that of the coupling unit 24, is extended upwards from the coupling unit 24, and a guide hole 34 for being inserted with the elevation member 18, is penetrated through and formed in the elevation member guide unit 26.

A separation prevention protrusion 36 is formed in the inner surface of the elevation member guide unit 26 in a circumferential direction, and a hooking rib 40 hooked with the cover 20, is formed in an outer surface of the elevation member guide unit 26 in a circumferential direction.

The elevation member 18 is inserted in the elevation member guide unit 26 of the main body 16, in which the elevation member 18 is moved up or down, and is formed with an discharging passage 42 in a longitudinal direction thereof, through which the contents is discharged, and with an opening and closing plate 44 having a disc shape in an enlarged diameter, the lower surface of the plate 44 being closely contacted with the inner portion of the sealing member 32, for performing sealing. Herein, an inflow opening 46 through which the contents stored in the vessel 10 flows into the discharging passage 42, is formed in the lower portion of the elevation member 18 in a circumferential direction when the elevation member 18 is moved down.

A protrusion unit 48 may be formed in the upper end of the elevation member 18 in a circumferential direction so that the user may easily bite the outer surface of the elevation member 18 with teeth or lips, and a hooking protrusion 38 hooked with a separation prevention protrusion 36 formed in the inner surface of the elevation member guide unit 26, is formed in a central outer surface of the elevation member 18.

Herein, the hooking between the hooking protrusion 38 and the separation prevention protrusion 36 prevents the elevation member 18 from separating from the main body 16 downward, and limits the moving distance of the elevation member 18.

A gap 60 through which air may pass, is formed between the elevation member 18 and the elevation member guide unit 26, the contents may be easily discharged without gurgling because external air flows into the vessel 10 through the gap 60 when the contents stored in the vessel 10 is discharged out through the discharging passage 42 of the elevation member 18.

Meanwhile, reinforcing rib 55 for structurally reinforcing a portion of the inflow opening 46 may be formed in one body in an inner surface of the elevation member 18 as shown in FIGS. 8 and 9. The reinforcing rib 55 may be formed in predetermined height from the lower end of the elevation member 18, particularly higher than the inflow opening 46, and the reinforcing rib 55 may have various shapes such as ‘−’ shape, ‘+’ shape, etc.

A rotation prevention unit 50 for preventing the elevation member 18 from being rotated, is formed between the outer surface of the elevation member 18 and the inner surface of the elevation member guide unit 26 of the main body 16.

The rotation prevention unit 50, as shown in FIG. 7, is comprised of at least one hooking protrusion 54 formed in the outer surface of the elevation member 18, the hooking rib protruding from the outer surface of the elevation member 18 in a regular interval in a circumferential direction of the elevation member 18, and at least one hooking groove 52 formed in the inner surface of the elevation member guide unit 26 in a regular interval in a circumferential direction, each hooking groove 52 being inserted with each hooking rib 54. In other words, since the hooking protrusion 54 is inserted into the hooking groove 52 when the elevation member 18 is inserted into the elevation member guide unit 26 of the main body 16, the movement of the elevation member 18 in upward and downward directions is possible but, the rotation of the elevation member 18 is prevented. In case that the sectional shape of the elevation member 18 is polygonal such as rectangular, etc., the shape of the elevation member 18, itself may be the rotation prevention unit 50. Herein, the inner surface of the elevation member guide unit 26 corresponding to the elevation member 18, has a shape corresponding to the sectional shape of the elevation member 18.

The cover 20 coupled with the outer surface of the elevation member guide unit 26 of the main body 16, performs a role for protecting the discharging passage 42 of the elevation member 18 discharging the contents, a plurality of protrusions are formed in the outer surface of the cover 20, so that a user may easily grip and rotate the cover 20 by hand, and a hooking protrusion 64 is formed in the inner surface of the lower portion of the cover 20, the hooking protrusion 64 being hooked with a hooking rib 40 formed in an outer surface of the elevation member guide unit 26.

Herein, the hooking protrusion 64 of the cover has the structure that the hooking protrusion 64 is separated from the hooking rib 40 which is formed in the outer surface of the elevation member guide unit 26 when predetermined upward force is applied to the hooking protrusion 64 in the hooking state that the hooking protrusion 64 is hooked with the hooking rib 40.

And a skirt unit 66 for fixing the cover 20 to the outer surface of the main body 16, is formed in a lower end of the cover 20 connected with the cover 20 by a plurality of connecting members 66a which is easily separated from the cover 20, and is separated from the cover 20 when the cover 20 is rotated by greater than predetermined rotation force, and then the cover 20 is separated from the main body 16.

An operation unit 70 for moving the elevation member 18 up or down in accordance with the rotation of the cover 20 in a positive direction or a negative direction, is formed between the cover 20 and the elevation member 18.

The operation unit 70 is comprised of a female screw unit 72 formed in the inner surface of the upper portion of the elevation member 18, a supporting unit 76 inserted in an inside of the elevation member 18, the supporting unit 76 protruding from the inner surface of the cover 20 from the upper inside portion of the cover 20 to the lower portion of the cover 20, in a cylindrical shape, and a male screw unit 74 formed in an outer surface of the supporting unit 76, and coupled with the female screw unit 72.

The operation of this operation unit 70 is that since the elevation member 18 is supported and prevented from being rotated at the inner surface of the elevation member guide unit 26 of the main body 16 by the rotation prevention unit 50, the hooking protrusion 64 of the cover 20 is hooked with the hooking rib 40 formed in the outer surface of the main body 16, and the female screw unit 72 of the elevation member 18 and the male screw unit 74 of the cover 70 is screw-connected with each other; the cover 20 performs idle rotation at the outer surface of the main body 16 when the cover is rotated, and the idle rotation of the cover 20 makes the female screw unit 72 of the elevation member 18 moved upward or downward along the male screw unit 74 of the cover unit 20.

Meanwhile, although not shown in the drawings, the operation unit 70 may be comprised of a male screw unit formed in the upper portion of the outer surface of the elevation member 18, and a female screw unit formed in the inner surface of the cover 20 screw-coupled with the corresponding male screw unit.

Operation of the closure of the vessel according to the present invention will be explained as follows.

FIGS. 10 to 13 are state views showing operation of the closure of the vessel in accordance with the first embodiment of the present invention.

In case that the closure of the vessel closes the entrance 12 of the vessel, the sealing member 32 is closely contacted with the upper surface of the entrance 12 of the vessel 10 in the outer portion thereof, and the sealing member 32 is closely contacted with the opening and closing plate 44 of the elevation member 32 in the inner portion thereof, and thereby seals the vessel 10. Therefore the vessel 10 storing the contents, is maintained in a sealed state.

From the above described state, firstly the cover 20 is rotated in a positive direction, when a user makes the contents stored in the vessel discharged out. Then, the skirt unit 66 is separated, and the cover 20 is rotated at the state of being separated from the main body 16. Herein, the cover 20 performs idle rotation because the hooking protrusion 64 is hooked with the hooking rib 40 formed in the outer surface of the main body 16.

In this manner, when the cover 20 is rotated, the opening and closing plate 44 is separated from the sealing member 32 according to the descent of the elevation member 18 by the operation unit 70 formed between the cover 20 and the elevation member 18, and thereby the vessel 10 is opened. In other words, since the elevation member 18 the hooking protrusion 54 of which is inserted into the hooking groove 52 formed in the elevation member guide unit 26 of the main body 16, is prevented from being rotated, the female screw unit 72 formed in the elevation member 18 is unfastened with the male screw unit 74 of the cover 20 when the cover 20 is rotated, and then the elevation member 18 is moved downward.

In this manner, the elevation member 18 continues descending, stops descending when the hooking protrusion 38 formed in the inner surface of the elevation member 18, is contacted with the separation prevention protrusion 36 formed in the inner surface of the elevation member guide unit 26, and then force which makes the cover 20 moved relatively upward, is applied when the cover 20 is further rotated, and thereby the hooking protrusion 64 of the cover 20 is separated from the hooking rib 40 formed in the main body 16. Then, the contents stored in the vessel 10 is flowed into the discharging passage 42 through the inflow opening 46 of the elevation member 18, and is discharged out through the discharging passage 42, when the vessel 10 is tilted after the cover 20 is removed from the main body 16.

Herein, a user may easily bite and suck the elevation member 18 because the end portion of the elevation member 18 is formed with a protrusion 48. And the contents may be more easily discharged out through the discharge passage 42 because external air is flowed into the inside of the vessel 10 through the gap 60 between the elevation member 18 and the elevation member guide unit 26 when the contents is discharged out through the discharging passage 42.

In case that a user wishes to seal the vessel 10 again after discharging a predetermined amount of the contents out, the male screw unit 74 of the cover 20 is fastened with the female screw unit 72 of the elevation member 18 by the rotation of the cover 20 in the opposite direction, and the elevation member 46 is ascended, after the cover 20 is covered to the main body 16. Then, the opening and sealing plate 44 is closely contacted with the sealing member 32, and the vessel 10 is sealed. And if the cover 20 continues being further rotated, the elevation member 18 may not be further ascended and the cover 20 is relatively descended because the opening and closing plate 44 is closely contacted with the sealing member 32. In other words, since the elevation member 18 may not be further ascended, if the female screw unit 72 of the elevation member 18 is fastened to the male screw unit 74, the cover 20 is descended and the hooking protrusion 64 passes over and is hooked with the hooking rib 40 of the main body 16.

FIGS. 14 to 17 are state views showing operation of the closure of the vessel in accordance with the second embodiment of the present invention, and FIG. 18 is a sectional view showing the closure of the vessel in B-B line in FIG. 14.

Meanwhile, if a user wishes to discharge the contents stored in the vessel out, the closure of the vessel according to the present invention needs to be maintained in descended state of the elevation member 18, and otherwise in ascended state of the elevation member 18 so that the contents stored in the vessel may not be leaked out.

Therefore, the elevation member guide unit 26 of the closure of the vessel in the first embodiment, in accordance with the second embodiment of the present invention, is further formed with a hooking maintaining protrusion 37 for maintaining the hooking state between the elevation member guide unit 26 and the hooking protrusion 38 formed in the elevation member 18. When the elevation member 18 is reached to the highest portion, the hooking maintaining protrusion 37 is hooked with the hooking protrusion 38, and the sealing member 32 is closely contacted with the entrance 12 of the vessel 10 in the outer portion of the sealing member 32, and with the elevation member 18 in the inner portion of the sealing member 32, and thereby the vessel 10 is sealed. The hooking state between the hooking protrusion 38 and the hooking maintaining protrusion 37, may be dissolved when a user applied more than a predetermined force.

Meanwhile, a descended state of the elevation member 18 by movement of the hooking protrusion 38 downward from the separation prevention protrusion 36, needs to be maintained, and the elevation member 18 needs to be prevented from being further descended. Therefore, a second hooking protrusion 39 may be further formed in the elevation member 18 above the hooking protrusion 28.

The second hooking protrusion 39 is formed in the outer surface of the elevation member 18, in order to prevent the hooking protrusion 28 from being further descended after the hooking protrusion 28 passes over the separation prevention protrusion 36 and is moved below the separation prevention protrusion 36, and the elevation member 18 from being descended by maintaining hooking state with the hooking maintaining protrusion 37 when the hooking protrusion 28 passes over the separation prevention protrusion 36.

Meanwhile, there is a problem that the movement of the elevation member 18 may be interfered with because the elevation member 18 is pressed by the elevation 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 vessel 10.

Therefore, at least one of the hooking protrusion 38 and the second hooking protrusion 39, may be made of flexible material, or as shown in FIG. 18, may be comprised of a plurality of protrusions 39a protruded outward from the outer surface of the elevation member 18. By the construction of the plurality of protrusions 39a of the hooking protrusion 38 and the second hooking protrusion 39, the elevation member 18 may be more easily moved up and down although the elevation member 18 is pressed by the elevation 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 vessel 10.

Meanwhile, the separation prevention protrusion 36 and the hooking maintaining protrusion 37 may be also comprised of a plurality of protrusions protruding inwards from the inner surface of the elevation member guide unit 26.

The closure of the vessel having the above described structure in accordance with the second embodiment of the present invention, may operate in a similar manner with the closure of the vessel in accordance with the first embodiment. But when the elevation member 18 finishes being descended, the hooking protrusion 38 is maintained to be hooked with the separation prevention protrusion 36 after passing the separation prevention protrusion 36, and at the same time, the second hooking protrusion 39 is maintained to be hooked with the hooking protrusion 37. Thereby, the elevation member 18 is maintained to be fixed, and the contents stored in the vessel 10 is flowed into the discharging passage 42 through the inflow opening 46 of the elevation member 18, and is discharged out through the discharging passage 42, when the vessel 10 is tilted.

Meanwhile, in case that the cover 20 is removed, the elevation member 18 may be also pulled or pushed by user's hand or mouth, and the vessel 10 may be sealed or opened.

In particular, the hooking protrusion 28 limits the movement of the elevation member 18 by passing over the hooking maintaining protrusion 37 and being maintained in the hooking state with the hooking maintaining protrusion 37, when the elevation member 18 is pulled to the highest position. Therefore, the vessel is maintained to be sealed by fixing the elevation member 18 although the cover 20 is removed.
