Definitions

  • the present invention relates to a valve device for a beverage vessel, and more particularly to a valve device for a beverage vessel which is installed at the opening of the beverage vessel and adapted to open and close the opening, thereby allowing the user to selectively drink the contents of the beverage vessel.
  • valve device In order to open and close the opening of a beverage vessel, a valve device is typically coupled to the opening.
  • valve devices there are two types, that is, a separable type in which the valve device is completely separated from the beverage vessel upon opening the beverage vessel, and an integral type in which the valve device opens the beverage vessel without being separated from the opening of the beverage vessel.
  • the integral type valve device For beverage vessels for use outdoors, the integral type valve device is mainly used in that it provides convenience in use.
  • the valve device includes a body 1 coupled to the opening of the beverage vessel denoted by the reference numeral 100, a sealing member 4 attached to the opening of the beverage vessel 100, a vertical slide member 2 fitted around an upper portion of the body 1 while being vertically slidable, and a lid 3 fitted around an intermediate portion of the body 1 while surrounding the vertical slide member 2.
  • the user first separates the body 1 from the beverage vessel 100, and then removes the sealing member 4. Thereafter, the user again couples the body 1 to the opening of the beverage vessel 100.
  • the user separates the lid 3 from the body 1, and then upwardly slides the vertical slide member 2 while grasping the vertical slide member 2 by the fingers, so that the upper surface 2a of the vertical slide member 2 is vertically spaced from the head portion la of the body 1.
  • the opening of the beverage vessel 100 is opened.
  • the user can drink the contents of the beverage vessel 100 by tilting the beverage vessel 100.
  • the user downwardly presses the vertical slide member 2 using his hand, thereby causing the vertical slide member 2 to return to its original position, that is, a closed position.
  • the opening of the beverage vessel 100 is closed.
  • valve device is inconvenient in use because it is necessary to perform procedures of separating the body 1 of the valve device from the beverage vessel 100, removing the sealing member 4, and then again coupling the separated body 1 to the beverage vessel 100, in order to use the valve device.
  • the user should upwardly move the vertical slide member 2 using his fingers. After drinking, the user has to downwardly move the vertical slide member 2 to its original position using his fingers.
  • there is a sanitation problem in that the portion of the valve device, from which the contents of the beverage vessel is discharged, may be contaminated upon opening or closing the valve device.
  • the conventional valve device has an insufficient sealing effect because it seals the opening of the beverage vessel only using the sealing member 4 having a thin disc structure. For this reason, this valve device has a problem in that it cannot be applied to beverage vessels adapted to contain carbonated beverages.
  • an object of the invention is to provide a valve device for a beverage vessel which is capable of conveniently and easily opening and closing the opening of the beverage vessel.
  • Another object of the invention is to provide a valve device for a beverage vessel which allows the user to open and close the opening of the beverage vessel without the user's fingers coming into contact with the opening of the beverage vessel, thereby maintaining the opening in a clean state.
  • Another object of the invention is to provide a valve device for a beverage vessel which is capable of reliably sealing the opening of the beverage vessel, so that it is applicable to beverage vessels containing carbonated beverages under pressure.
  • Another object of the invention is to provide a valve device for a beverage vessel which is capable of achieving a simple and convenient assembly process thereof.

Description

CLOSER OF BEVERAGE VESSEL
Technical Field
The present invention relates to a valve device for a beverage vessel, and more particularly to a valve device for a beverage vessel which is installed at the opening of the beverage vessel and adapted to open and close the opening, thereby allowing the user to selectively drink the contents of the beverage vessel.
Background Art
In order to open and close the opening of a beverage vessel, a valve device is typically coupled to the opening. Among such valve devices, there are two types, that is, a separable type in which the valve device is completely separated from the beverage vessel upon opening the beverage vessel, and an integral type in which the valve device opens the beverage vessel without being separated from the opening of the beverage vessel. For beverage vessels for use outdoors, the integral type valve device is mainly used in that it provides convenience in use.
Referring to Fig. 19, a conventional integral type valve device for a beverage vessel is illustrated. As shown in Fig. 19, the valve device includes a body 1 coupled to the opening of the beverage vessel denoted by the reference numeral 100, a sealing member 4 attached to the opening of the beverage vessel 100, a vertical slide member 2 fitted around an upper portion of the body 1 while being vertically slidable, and a lid 3 fitted around an intermediate portion of the body 1 while surrounding the vertical slide member 2. Where it is desired to drink the contents of the beverage vessel 100, the user first separates the body 1 from the beverage vessel 100, and then removes the sealing member 4. Thereafter, the user again couples the body 1 to the opening of the beverage vessel 100. In this state, the user separates the lid 3 from the body 1, and then upwardly slides the vertical slide member 2 while grasping the vertical slide member 2 by the fingers, so that the upper surface 2a of the vertical slide member 2 is vertically spaced from the head portion la of the body 1. As a result, the opening of the beverage vessel 100 is opened. In this state, the user can drink the contents of the beverage vessel 100 by tilting the beverage vessel 100. When the user does not wish to further drink the contents of the beverage vessel 100, the user downwardly presses the vertical slide member 2 using his hand, thereby causing the vertical slide member 2 to return to its original position, that is, a closed position. Thus, the opening of the beverage vessel 100 is closed. However, this valve device is inconvenient in use because it is necessary to perform procedures of separating the body 1 of the valve device from the beverage vessel 100, removing the sealing member 4, and then again coupling the separated body 1 to the beverage vessel 100, in order to use the valve device. Furthermore, where it is desired- to drink the contents, of the beverage vessel 100, the user should upwardly move the vertical slide member 2 using his fingers. After drinking, the user has to downwardly move the vertical slide member 2 to its original position using his fingers. As a result, there is a sanitation problem in that the portion of the valve device, from which the contents of the beverage vessel is discharged, may be contaminated upon opening or closing the valve device.
Furthermore, the conventional valve device has an insufficient sealing effect because it seals the opening of the beverage vessel only using the sealing member 4 having a thin disc structure. For this reason, this valve device has a problem in that it cannot be applied to beverage vessels adapted to contain carbonated beverages.
Disclosure of the Invention
Therefore, the present invention has been made in view of the above mentioned problems involved with the prior art, and an object of the invention is to provide a valve device for a beverage vessel which is capable of conveniently and easily opening and closing the opening of the beverage vessel.
Another object of the invention is to provide a valve device for a beverage vessel which allows the user to open and close the opening of the beverage vessel without the user's fingers coming into contact with the opening of the beverage vessel, thereby maintaining the opening in a clean state. Another object of the invention is to provide a valve device for a beverage vessel which is capable of reliably sealing the opening of the beverage vessel, so that it is applicable to beverage vessels containing carbonated beverages under pressure. Another object of the invention is to provide a valve device for a beverage vessel which is capable of achieving a simple and convenient assembly process thereof.
In accordance with the present invention, these objects are accomplished by providing a valve device for a beverage vessel which includes a body coupled to the opening of the beverage vessel, a lid rotatably fitted around the body, and a vertical moving member fitted in the body to be vertically movable, and adapted to move downwardly when the lid rotates normally, thereby opening the opening of the beverage vessel, while moving upwardly when the lid rotates reversely, thereby closing the opening of the beverage vessel.
When the lid rotates, the vertical moving member is vertically moved. Accordingly, the opening of the beverage vessel can be conveniently opened and closed. Since the user can open and close the opening of the beverage vessel without the user's fingers coming into contact with the opening of the beverage vessel, it is possible to maintain the opening in a clean state. Accordingly, an improved sanitation effect is obtained.

Best Mode for Carrying Out the Invention
Fig. 1 is an exploded perspective view illustrating a valve device for a beverage vessel according to a first embodiment of the present invention. Fig. 2 is a sectional view illustrating the valve device mounted to a beverage vessel.
As shown in Figs. 1 and 2, the valve device according to the first embodiment of the present invention includes a body 10 coupled to the opening
100a of a beverage vessel 100, a vertical moving member 20 fitted in the body
10, and adapted to move vertically, thereby opening or closing the opening 100a of the beverage vessel 100, and a lid 30 fitted around the body 10, and adapted to vertically move the vertical moving member 20. -
The body 10 includes upper and lower hollow cylindrical sections 11 and 12 each opened at both vertical ends thereof. The lower cylindrical section 12 is provided at its inner surface with female threads 14 to be threadedly coupled with male threads 100b formed at the opening of the beverage vessel 100.
The upper cylindrical section 11 has a diameter smaller than that of the lower cylindrical section 12. The upper and lower cylindrical sections 11 and 12 are connected to each other at their adjacent ends by an annular flat connecting section 13. The annular flat connecting section 13 has an inner peripheral edge inwardly protruded beyond the peripheral edge of the opening 100a of the beverage vessel 100, so that it can come into contact with the upper end of the opening 100a at its lower surface. As shown in Figs. 2 and 3, the upper cylindrical section 1 1 is provided at a lower portion thereof with eight vertical grooves 15 formed at the inner surface of the upper cylindrical section 11 while being uniformly spaced apart from one another. The upper cylindrical section 11 is also provided with an inwardly-protruded annular lip 16 above the vertical grooves 15.
The annular lip 16 is formed at the lower end of an inner cylindrical section 18 arranged inside the upper cylindrical section 11 and connected at an upper end thereof to the inner surface of the upper cylindrical section 1 1. An annular protrusion 18a is formed at the inner surface of the inner cylindrical section 18.
A skirt member 12a extends downwardly from the lower end of the lower cylindrical section 12 so that it comes into close contact with the outer surface of the beverage vessel around the vessel opening in the assembled state of the valve device. When the body 10 is rotated, it is separated from the skirt member 12a, so that it is separated from the vessel opening.
As shown in Figs. 1, 2, and 3, the vertical moving member 20 includes a column 22 fitted in the upper cylindrical section 11 of the body 10 and formed with a plurality of ribs 21 extending radially outwardly around the center of the column 22, and a disc-shaped sealing plate 25 formed at the lower end of the column 22. Each rib 21 has a guide portion 21a formed at the lower portion of the rib 21 , and adapted to be engagable with one of the vertical grooves 15 at an outer end thereof, a head portion 21c formed at the. upper portion of the rib 21, and radially outwardly protruded to have a radial length less than that of the guide portion 21a. The head portion 21c is formed at an outer end thereof with male threads 2 Id. The rib 21 also has a neck portion 21b formed between the head portion 21c and the guide portion 21a, and radially outwardly protruded to have a radial length less than that of the head portion 21c.
The sealing plate 25 is disposed beneath the annular connecting section
13 of the body 10. The head portion 21c is outwardly protruded beyond the annular lip 16 of the upper cylindrical section 11 while being arranged above the annular lip 16. The neck portion 21b has a short radial length such that it does not come into contact with the annular lip 16.
The sealing plate 25 has a diameter larger than the inner diameter of the annular connecting section 13 of the body 10 while being smaller than the inner diameter of the vessel opening 100a. Accordingly, the sealing plate 25 can completely seal an opening defined by the inner peripheral edge of the annular connecting section 13.
As shown in Figs. 1 and 2, the lid 30 is fitted around the upper cylindrical section 11 of the body 10. The lid 30 has a top wall section 31, an outer wall section 32, and an inner cylindrical section 33. The inner cylindrical section 33 extends downwardly from the lower surface of the top wall section 31 inside the outer wall section 32 while being inwardly spaced apart from the outer wall section 32. The inner cylindrical section 33 is formed at its inner surface with female threads 33d to be engaged with the male threads 2 Id of the neck portion 21c. The lid 30 is also provided at its lower end with a seal strip 34. An annular step 34a is formed at the inner surface of the seal strip 34.
The male threads 2 Id formed at the head portion 21c of the vertical moving member 20 are downwardly inclined, whereas the female threads 33d formed at the inner surface of the inner cylindrical section 33 are upwardly inclined. Accordingly, the engagement between the male threads 21d and the female threads 33d can be easily achieved by simply inserting the vertical moving member 20 into the upper cylindrical section 11.
Meanwhile, a sealing member 40 is bonded to the lower surface of the annular connecting section 13 of the body 10.
In place of the sealing member 40, the annular connecting section 13 of the .body 10 may be formed at its lower surface with an annular sealing portion (not shown) downwardly protruded from the lower surface. Accordingly, a sealing effect is obtained between the opening 100a of the beverage vessel 100 and the annular connecting section 13 at a region 13a, and between the annular connecting section 13 and the sealing plate 25 by the sealing member 40 or annular sealing portion.
As shown in Fig. 5, the seal strip 34 is connected to the outer wall section 32 of the lid 30 by connecting pieces 35. When the lid 30 is rotated, the connecting pieces 35 are cut, thereby causing the outer wall section 32 of the lid 30 to be separated from the seal strip 34. The seal strip 34 is provided at its inner surface with a cutting portion 36 to be cut simultaneously with the cutting of the connecting pieces 35.
Now, the process for assembling the elements of the valve device having the above described configuration will be described in conjunction with Figs. 1 and 2.
First, the sealing member 40 is bonded to the lower surface of the annular connecting section 13 of the body 10. In this state, the vertical moving member 20 is upwardly inserted into the body 10 at the lower end of the body
10. In accordance with the insertion of the vertical moving member 20, the ribs
21 of the vertical moving member 20 pass through the opening defined by the inner peripheral edge of the annular connecting section 13. The insertion of the vertical moving member 40 is carried out until the sealing plate 25 of the vertical moving member 20 comes into contact with the sealing member 40. During the insertion of the vertical moving member 40, the head portion 21c of the vertical moving member 40 moves upwardly while radially pushing the annular lip 16, and finally reaches the upper portion of the upper cylindrical section 1 1.
Also, each guide portion 21a of the vertical moving member 20 is received in one of the vertical grooves 15 formed at the inner peripheral surface of the upper cylindrical section 1 1.
Subsequently, the lid 30 is fitted around the upper cylindrical section 1 1 of the body 10 so that the female threads 33d formed at the inner cylindrical section 33 of the lid 30 are engaged with the male threads 21b formed at the head portion 21c of the vertical moving member 20. At this time, the annular step 34a formed at the seal strip 34 comes into tight contact with the lower portion of the upper cylindrical section 1 1. Thus, the assembly process for the elements of the valve device is completed.
The assembled valve device of the present invention is threadedly coupled to the opening 100a of the beverage vessel 100, as shown in Fig. 2.
Now, the method of using the valve device coupled to the beverage vessel 100 will be described.
Fig. 2 illustrates the state in which the opening of the beverage vessel is closed by the valve device according to the present invention. Fig. 6 illustrates the state in which the opening of the beverage vessel is opened by the valve device.
When the user applies a rotating force to the lid 30 in a normal direction in the state of Fig. 2, the lid 30 is rotated while being separated from the seal strip 34. As the lid 30 is normally rotated, the vertical moving member 20 threadedly coupled to the lid 30 is downwardly moved. That is, the vertical moving member 20 moves downwardly without rotating because each guide portion 21a thereof is engaged with one of the vertical grooves 15 of the upper cylindrical section 11 at its outer end. As the lid 30 is further normally rotated, the vertical moving member 20 is further downwardly moved, so that its threaded coupling to the lid 30 is released.
In accordance with the downward movement of the vertical moving member 20, the sealing plate 25 is separated away from the sealing member 40, thereby causing the vessel opening to be opened. When the lid 30 is separated from the body 1 in a state of Fig. 6, and then the beverage vessel 100 is inclined, the beverage contained in the beverage vessel 100 is discharged from the beverage vessel 100 via a space defined between the sealing member 40 and the sealing plate 25, and a space defined between adjacent ones of the ribs 21. Thus, the user can drink the discharged beverage. When the vertical moving member 20 releases its threaded coupling to the lid 30, the head portion 21c of the vertical moving member 20 comes into contact with the annular lip 16 of the upper cylindrical section 11 at its lower surface, as shown in Fig. 6. As a result, the annular lip 16 prevents any further downward movement of the vertical moving member 20. Accordingly, the vertical moving member 20 is prevented from being separated from the upper cylindrical section 1 1 to fall into the beverage vessel 100.
Since the annular protrusion 18a of the inner cylindrical section 18 comes into tight contact with the outer surface of the head portion 21c, it is possible to prevent the vertical moving member 20 from moving laterally. In a state in which, although the lid 30 has been separated from the vertical moving member 20, it is not separated from the body 10 yet, the head portion 21c downwardly presses the annular lip 16 at its lower surface, thereby causing the inner cylindrical section 18 to be slightly widened in a radial direction. When the lid 30 is separated from the body 10, the vertical moving member 20 is slightly moved in the upward direction by the resilience of the inner cylindrical section 18 and the resilience of the annular lip 16.
When the user desires to close the opening 100a of the beverage vessel 100 after drinking the contents of the beverage vessel 100, he first fits the lid 30 around the upper cylindrical section 11 of the body 10, and then reversely rotates the lid 30. In accordance with the reverse rotation of the lid 30, the vertical moving member 20, which is in a slightly raised state by virtue of the resilience of the annular lip 16, is threadedly engaged with the lid 30, so that it is upwardly moved. The upward movement of the vertical moving member 20 is carried out until the sealing plate 25 of the vertical moving member 20 comes into close contact with the sealing member 40. As a result, the opening 100a of the beverage vessel 100 is closed.
In the illustrated embodiment of the present invention, the sealing member 40 is attached to the lower surface of the annular connecting section 13 of the body 10. However, the sealing member 40 may be dispensed with. In this case, the sealing plate 25 of the vertical moving member 20 is configured to come into direct contact with the annular connecting section 13, thereby closing the opening the beverage vessel.
Although not shown, lid attaching means may be provided at the body 10 so as to temporarily attach the lid 30, separated from the body 10, to the body 10, thereby keeping the lid 30.
The lid attaching means may comprise a vertically-extending protrusion formed at the outer surface of the lid 30, and a vertically-extending groove adapted to be engaged with the protrusion. In this case, the protrusion of the lid 30 can be engaged with the groove of the body 10 in a state in which the lid 30 is separated from the body 10. Accordingly, the separated lid 30 can be kept in a state in which it is attached to the body 10.
. A small hole may be perforated at the lower portion of the upper cylindrical section 11 covered by the seal strip 34 so as to allow air to be introduced into the interior of the beverage vessel when the user drinks the contents of the beverage vessel.
Figs. 7 to 9 illustrate a valve device for a beverage vessel according to a second embodiment of the present invention. In the second embodiment of the present invention, elements respectively corresponding to those of the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof will be omitted.
The valve device according to the second embodiment of the present invention includes a body 10, a lid 30 rotatably fitted around the body 10, and a vertical moving member 20' fitted in the body 10, and adapted to move vertically.
The vertical moving member 20' includes a sealing plate 25', a plurality of vertical ribs 21 ' respectively formed on the sealing plate 25' at positions radially spaced apart from the center of the sealing plate 25' to extend upwardly and radially while being spaced apart from one another, a hollow cylindrical neck 22' arranged inside the vertical ribs 21 ' while extending upwardly from a position upwardly spaced apart from the sealing plate 25' by a desired distance, and a cylindrical head 23' extending upwardly from the neck 22' while having a diameter larger than the neck 22'. The cylindrical head 23' is formed with female threads 23a' at the inner surface thereof.
The lid 30 has a top wall section 31, an outer wall section 32, and an inner cylindrical section 33'. The inner cylindrical section 33' extends downwardly from the lower surface of the top wall section 31 inside the outer wall section 32. The inner cylindrical section 33' is formed at its outer surface with male threads 33a' to be engaged with the female threads 23a' of the neck 21c.
Each rib 21 ' of the vertical moving member 20' is received in one of the vertical grooves 15 at an outer end thereof such that it is vertically movable along the vertical groove 15.
In the valve device having the above described configuration according to the second embodiment of the present invention, when the lid 30 rotates normally, the vertical moving member 20' is downwardly moved, thereby causing the sealing plate 25' to be spaced apart from the sealing member 40. Accordingly, the opening 100a of the beverage vessel 100 is opened. When the beverage vessel is inclined in a state in which the threaded coupling between the lid 30 and the vertical moving member 20' is released, the contents of the beverage vessel 100 is discharged via a space defined between the sealing plate 25' and the sealing member 40, a space defined between adjacent ones of the ribs 21 ', and a space 22a' defined in the neck 22'a and head 23'.

This valve device includes a body 110 coupled to the opening of a beverage vessel 100, a lid 120 detachably and rotatably fitted around an upper portion of the body 1 10, and a vertical moving member 130 fitted in the body 1 10 such that it is vertically movable. The vertical moving member 130 is threadedly coupled to the inner peripheral surface of the lid 120 so as to open the opening of the beverage vessel 100 when it is downwardly moved in accordance with a normal rotation of the lid 120, while closing the opening of the beverage vessel 100 when it is upwardly moved in accordance with a reverse rotation of the lid 120. The valve device also includes an annular sealing member 140 fitted around the vertical moving member 130, and arranged between the opening of the beverage vessel 100 and a desired portion of the body 1 10 in order to provide a sealing effect therebetween.
The body 110 includes a lower cylindrical section 111 threadedly coupled to the opening of the beverage vessel 100, an upper cylindrical section 1 12 having a diameter smaller than that of the lower cylindrical section 1 1 1 while being provided at its outer surface with threads 1 12' threadedly coupled to the lower portion of the lid 120, and an annular connecting section 1 13 extending radially between the upper end of the lower cylindrical section 11 1 and the lower end of the upper cylindrical section 1 12, and arranged over the opening of the beverage vessel 100. The sealing member 140 is attached to the lower surface of the annular connecting section 1 13. In order to prevent loss of the lid 120, a plurality of engagement protrusions 1 14 are radially protruded from the outer surface of the lower cylindrical section 11 1.
The lid 120 includes an upper section formed at its inner peripheral surface with first threads 121 ' adapted to be threadedly coupled to the vertical moving member 130, an a lower section 122 connected to the upper section 121 while having a diameter larger than that of the upper section 121. The lower section 122 is formed at its inner peripheral surface with second threads 122' adapted to be threadedly coupled to the threads 112' of the upper cylindrical section 112. The lower section 122 is also formed at its outer peripheral surface with a plurality of protrusions 123 adapted to be selectively engaged between adjacent ones of the engagement protrusions 114 formed at the body 110. A seal strip 124 is provided at the lower end of the lower section 122 in order to indicate whether or not the lid 120 is intact.
The vertical moving member 130 includes a hollow upper section 131 having a cylindrical shape while being formed at its outer peripheral surface with threads 131 ', and a hollow lower section 132 connected at its upper end to the lower end of the upper section 131, and formed at its outer peripheral surface with a guide 134 adapted to guide a vertical movement of the vertical moving member 120 in cooperation with the upper cylindrical section 112 of the body 1 10. The lower section 132 is also provided with a plurality of through holes 132' for communicating the interior of the vertical moving member 130 with the outside of the vertical moving member 130. The vertical moving member 130 also includes a disc-shaped sealing plate 133 connected to the lower end of the lower section 132, and adapted to seal an opening formed at the sealing member 140. The guide 134 is received in a guide groove (not shown) formed at the inner peripheral surface of the upper cylindrical section 1 12 in order to prevent the vertical moving member 120 from rotating. The lower end of each through hole 132' is spaced apart from the surface of the sealing plate 133 by a distance more than the thickness of the sealing member 140. Now, the process for assembling the elements of the valve device having the above described configuration will be described.
First, the sealing member 140 is bonded to the lower surface of the annular connecting section 1 13 of the body 1 10. In this state, the vertical moving member 130 is upwardly inserted into the body 1 10 at the lower end of the body 1 10 such that its upper section 131 is upwardly moved through the opening of the sealing member 140. At this time, the guide 134 formed at the lower cylindrical section is received in the guide groove formed at the upper cylindrical section 1 12 of the body 1 10. The insertion of the vertical moving member 130 is carried out until the sealing plate 133 of the vertical moving member 130 comes into contact with the sealing member 140, thereby closing the opening of the sealing member 140. At this time, the upper section 131 of the vertical moving member 130 is outwardly protruded from the upper cylindrical section 112 of the body 1 10. In this state, the lid 120 is threadedly coupled to the outer peripheral surface of the upper cylindrical section 1 12 of the body 110 while being simultaneously threadedly coupled to the upper section 131 of the vertical moving member 130. Thereafter, the lower cylindrical section 1 11 of the body 110 is threadedly coupled to the opening of the beverage vessel 100 such that the sealing member 140 seals the opening of the beverage vessel 100. Thus, the assembly process for the elements of the valve device is completed.
When the lid rotates, the rotating member is rotated, thereby causing the vertical moving member to be vertically moved. Accordingly, the opening of the beverage vessel can be conveniently opened and closed. In accordance with the valve device assembled through the above described procedure, the opening of the beverage vessel can be opened and closed only by rotation of the lid without any separation of the body from the beverage vessel. Accordingly, it is possible to maintain the opening of the beverage vessel in a clean state. When the user normally rotates the lid 120 in a stage of grasping the lid
120 by the fingers, the lid 120 is separated from the seal strip 124, and subsequently rotated. As the lid 120 rotates normally, the vertical moving member 130 threadedly coupled to the lid 120 is downwardly moved. That is, the vertical moving member 20 moves downwardly without rotating because the guide 134 of its lower section 132 is received in the guide groove of the upper cylindrical section 1 12.
In accordance with the downward movement of the vertical moving member 130, the sealing plate 133 of the vertical moving member 130 is spaced away from the sealing member 140, so that the through holes 132' formed at the lower section 132 of the vertical moving member 130 is exposed to the interior of the beverage vessel 100. Thus, the vessel opening is opened.
When the user separates the lid 120 from the upper cylindrical section 1 12 of the body 110, and then inclines the beverage vessel 100, he can drink the beverage contained in the beverage vessel 100. That is, the contents of the beverage vessel 100 are introduced into the vertical moving member 130 through the through holes 132', and then discharged from the outwardly-exposed upper section 131 of the vertical moving member 130. During the discharge of the beverage, air is introduced between the outer peripheral surface of the vertical moving member 130 and the inner peripheral surface of the upper cylindrical section 1 12 of the body 1 10. Thus, the discharge of the beverage can be easily carried out.
Meanwhile, it is possible to prevent loss of the lid 120 by engaging one of the protrusions 123, provided at the lid 120, between optional adjacent ones of the engagement protrusions 114 provided at the body 110, as shown An Fig. 13. The engagement of the protrusion 123 with the engagement protrusions 114 may be carried out in either the normal or reverse direction.
When the user desires to close the opening of the beverage vessel 100 after drinking the contents of the beverage vessel 100, he couples the separated lid 120 to the upper cylindrical section 112 of the body 110. When the lid 120 is subsequently rotated in a reverse direction, the upper section 131 of the vertical moving member 130 is threadedly coupled to the upper cylindrical section 121 of the lid 120. Accordingly, the vertical moving member 130 is upwardly moved as the lid 120 is further rotated in the reverse direction. The upward movement of the vertical moving member 130 is carried out until the sealing plate 133 of the vertical moving member 130 comes into close contact with the sealing member 140. As a result, the opening of the beverage vessel 100 is closed.
Referring to Figs. 14 and 15 illustrate a valve device for a beverage vessel according to a fourth embodiment of the present invention. This valve device includes a body 210 coupled to the opening 100a of a beverage vessel 100, a vertical moving member 220 rotatably fitted in the body 210, and adapted to open and close the opening 100a of the beverage vessel 100, and a lid 30 fitted around the body 210, and adapted to rotate the vertical moving member 220.
As shown in Figs. 14 and 15, the body 210 includes upper and lower hollow cylindrical sections 21 1 and 212 each opened at both vertical ends thereof. The lower cylindrical section 212 is provided at its inner surface with female threads 214 to be threadedly coupled with male threads 100b formed at the opening of the beverage vessel 100.
The upper cylindrical section 21 1 has a diameter smaller than that of the lower cylindrical section 212. The upper and lower cylindrical sections 21 1 and 212 are connected to each other at their adjacent ends by an annular flat connecting section 213. The annular flat connecting section 213 has an inner peripheral edge inwardly protruded beyond the peripheral edge of the opening 100a of the beverage vessel 100, so that it can come into contact with the upper end of the opening 100a at its lower surface.
The upper cylindrical section 211 is provided at an intermediate portion thereof with female threads 215 formed on the inner surface of the upper cylindrical section 211. The upper cylindrical section 21 1 is also provided with an inwardly-protruded annular lip 216 above the female threads 215.
Although not shown, a skirt member extends downwardly from the lower end of the lower cylindrical section 212 so that it comes into close contact with the outer surface of the beverage vessel around the vessel opening in the assembled state of the valve device. When the body 210 is rotated, it is . separated from the skirt member, so that it is separated from the vessel opening.
As shown in Figs. 14, 15, 17a, and 17b, the vertical moving member 220 includes a column 222 fitted in the upper cylindrical section 211 of the body 210 and formed with a plurality of ribs 221 extending radially outwardly around the center of the column 222, a neck 223 formed at the upper end of the column 222 to extend upwardly, engagement protrusions 224 formed at the upper end of the neck 223 to extend radially outwardly, and a disc-shaped sealing plate 225 formed at the lower end of the column 222. The ribs 221 have male threads 221a adapted to be threadedly coupled with, the female threads 215 of the upper cylindrical section 21 1. The sealing plate 225 is positioned beneath the annular connecting section 213 of the body 210. The engagement protrusions 224 are outwardly protruded beyond the annular lip 216 of the upper cylindrical section 21 1 while being arranged above the annular lip 216. The sealing plate 225 has a diameter larger than the inner diameter of the annular connecting section 213 while being smaller than the inner diameter of the vessel opening 100a. Accordingly, the sealing plate 225 can completely seal the opening defined inside the annular connecting section 213, beneath the annular connecting section 213. A recess 226 is formed at the lower end of the vertical moving member
220 so as to reduce the amount of the material used to manufacture the vertical moving member 220 while achieving an improved workability in the assembly process.
As shown in Figs. 14, 15, 16a, and 16b, the lid 230 is fitted around the upper cylindrical section 211 of the body 210. The lid 230 is provided at the inner surface of its top portion with a plurality of protrusions 231 extending downwardly while being arranged to be uniformly spaced apart from one another in a circumferential direction. As shown in Fig. 18, each protrusion 231 is engaged between adjacent ones of the engagement protrusions -224 of the vertical moving member 220. The lid 230 is also provided at its lower end with a seal strip 232. An annular step 232a is formed at the inner surface of the seal strip 232.
The male threads 221a formed at the ribs 221 of the vertical moving member 220 are downwardly inclined, whereas the female threads 215 formed at the inner surface of the inner cylindrical section 211 are upwardly inclined.
Accordingly, the engagement between the male threads 221a and the female threads 215 can be easily achieved by simply inserting the vertical moving member 220 into the upper cylindrical section 21 1. Meanwhile, a sealing member 240 is attached to the lower surface of the annular connecting section 213 of the body 210.
Although not shown, the annular connecting section 213 of the body 210 may be formed at its lower surface with an annular sealing portion downwardly protruded from the lower surface. By the annular sealing portion, a sealing effect is obtained between the opening 100a of the beverage vessel 100 and the annular connecting section 213 at a region 13 a, and between the annular connecting section 213 and the sealing plate 225 by the annular sealing portion.
In this case, the sealing member 240 can be dispensed with.
