The present disclosure relates to a beverage container and a cover unit. The beverage container includes a container body and a cover unit.
For instance, a beverage container includes a cylindrical container made of stainless steel and a cover detachably arranged on an opening of the container. Not only water, tea and fruit juice can be put into the beverage container, but also carbonate beverages can be put into it in some cases. Internal pressure of the container rises to push a cover in a highly-airtight beverage container. Sometimes the pressure makes the cover difficult to remove. In addition, the internal pressure is suddenly relieved from an opening when the cover is removed, which may cause loud noise or a beverage to be ejected.
Patent 1 discloses a container having a cover, in which a cover body can be easily and safely removed. The cover body of the container having a cover includes: an outer cover covering an opening part; an inner cover embedded into an inner side of a main container body from the opening part; a sealing member sealing a gap between the main container body and the inner cover when being mounted on an outer circumference of the inner cover; an inner plug located in a center of an inner side of the outer cover and embedded in an inner side of the inner cover; and a gasket located in a center of a bottom of the inner plug and blocking a ventilation hole in a center of the inner cover.
Patent 2 discloses a liquid container, in which a gasket is provided with a pressure regulating port, a pressure relief channel, and a pressure regulating valve. In the liquid container, the pressure regulating valve closes the pressure regulating port when internal pressure in a main container body is normal and opens the pressure regulating port when the internal pressure is high.
In a beverage container, even when a valve mechanism configured to relieve internal pressure of a container body is arranged, sufficient airtightness of the container body needs to be ensured. Moreover, in the beverage container, ease of opening a cover and convenience of widening an opening (including ease of accommodating or pouring out a beverage, and ease of drinking) can be obtained.
An objective of the present disclosure is to provide a beverage container and a cover unit, which can automatically relieve pressure when the internal pressure of a container body exceeds specified pressure, and control the internal pressure to be within a certain range, and are easy to open even when the internal pressure rises.
An embodiment of the present disclosure is a beverage container. The beverage container includes a container body having an opening at an upper portion; and a cover unit mounted on the opening of the container body. The cover unit includes: a cover body detachably mounted on the container body; a ventilation pipe mounted on an inner side of the cover body and having a ventilation path penetrating from an upper end to a lower end; and a pressure regulating valve arranged between the upper end of the ventilation pipe and the cover body and composed of an elastic member covering a ventilation hole on an upper end of the ventilation path. The cover body is mounted on the container body, a gap between the ventilation pipe and the opening is sealed, and the pressure regulating valve is clamped between the cover body and the ventilation pipe through a specified pressing force. In this way, the ventilation hole is closed by means of the pressure regulating valve.
According to the structure, the cover body is mounted on the container body, such that airtightness between the ventilation pipe and the opening can be ensured. In addition, the cover body is mounted on the container body, and the pressure regulating valve is clamped between the cover body and the ventilation pipe through the specified pressing force, such that the pressure regulating valve may reliably close the ventilation hole so as to ensure airtightness. Since the ventilation pipe is mounted on the inner side of the cover body, the ventilation pipe is removed while the cover body is removed, and the opening may be opened in a widened manner. In addition, when the internal pressure exceeds the specified pressing force, the pressure regulating valve is deformed, such that the blocked ventilation hole is opened, and the internal pressure is controlled to be within a specified value.
In the beverage container, the ventilation pipe is arranged to be mounted on the cover body in a fitting manner and is movable in a vertical direction relative to the cover body. In this way, the pressing force applied to the ventilation hole may be ensured to be a specified value through an elastic force of the pressure regulating valve. In addition, the ventilation pipe is movably fitted to the cover body in the vertical direction. When the cover body is removed from the container body, the ventilation pipe may be removed later than the cover body in a vertical moving range. That is, when the cover body is removed from the container body, removal of the cover body is firstly started under the condition that the ventilation pipe remains, and then removal of the ventilation pipe is started. In this way, the ventilation hole is opened before the opening is opened.
In the beverage container, the cover body may include: a cover part covering the opening; and a cover screwing part extending downward in a cylindrical shape from a center of the cover part and mounted on the container body through screwing. The ventilation pipe is arranged to be mounted on an inner side of the cover screwing part in a fitting manner and is movable in a vertical direction relative to the cover screwing part. The cover screwing part is screwed to the container body, the container body is pressed by the cover screwing part, and the ventilation pipe is clamped between the cover screwing part and the container body. In this way, the cover body is mounted on the container body through screwing, such that high airtightness is ensured.
In the beverage container, the pressure regulating valve may be in a capped cylindrical shape having an opening on a lower end and a top on an upper end, and cover an upper portion of the ventilation pipe. In this way, a valve mechanism is formed by covering the upper portion of the ventilation pipe with the pressure regulating valve. In addition, the pressure regulating valve may be simply assembled and disassembled, such that replacement ease and maintainability of the pressure regulating valve are improved.
In the beverage container, the ventilation path of the ventilation pipe is preferably provided with a reducing part having an inner diameter reduced from bottom to top. A thickness of the reducing part is regulated, such that pressure relieved from the pressure regulating valve can be controlled to be a specified value.
In the beverage container, the container body may include: a main container body having a container opening at an upper portion; a drinking mouth body mounted on the container opening of the main container body and having the opening at an upper portion and an annular sheet at a lower portion; and a first sealing part configured to seal a gap between an inner circumference of the container opening of the main container body and an outer circumference of the drinking mouth body. The cover unit further includes a second sealing part configured to seal a gap between an inner circumference of the drinking mouth body and an outer circumference of the ventilation pipe. The cover screwing part is screwed to an inner side of the drinking mouth body. The cover screwing part is screwed to the drinking mouth body. The container body is pressed by the cover screwing part. A gap between the ventilation pipe and the annular sheet of the drinking mouth body is sealed with the second sealing part. In this way, airtightness between the drinking mouth body and the main container body can be ensured with the first sealing part, and airtightness between the drinking mouth body and the ventilation pipe can be ensured with the second sealing part. In addition, since the second sealing part has a smaller diameter than the first sealing part, friction between the cover body and the drinking mouth body may be smaller than that between the drinking mouth body and the main container body, and the cover body may be opened more early than the drinking mouth body when the cover is opened. In this way, ease of opening the cover can be improved, and the container is convenient to use.
Another embodiment of the present disclosure is a cover unit. The cover unit is mounted on an opening of a container body having the opening at an upper portion and includes: a cover body detachably mounted on the container body; a ventilation pipe mounted on an inner side of the cover body and having a ventilation path penetrating from an upper end to a lower end; and a pressure regulating valve arranged between the upper end of the ventilation pipe and the cover body and composed of an elastic member covering a ventilation hole on an upper end of the ventilation path. The cover body is mounted on the container body. A gap between the ventilation pipe and the opening is sealed. The pressure regulating valve is clamped between the cover body and the ventilation pipe through a specified pressing force. In this way, the ventilation hole is closed by means of the pressure regulating valve.
According to the structure, the cover body is mounted on the container body, such that airtightness between the ventilation pipe and the opening can be ensured. In addition, the cover body is mounted on the container body, and the pressure regulating valve is clamped between the cover body and the ventilation pipe through the specified pressing force, such that the pressure regulating valve may reliably close the ventilation hole so as to ensure airtightness. Since the ventilation pipe is mounted on the inner side of the cover body, the ventilation pipe is removed while the cover body is removed, and the opening may be opened in a widened manner.
The present disclosure can provide the beverage container and the cover unit, which includes the relief mechanism for the internal pressure of the container body, and meanwhile, can fully ensure airtightness and obtain convenience in a cover-opened state.
Embodiments of the present disclosure will be described below with reference to the accompanying drawings. In addition, the same components are labeled as the same symbol in the following description, and description of the described components is appropriately omitted.
The beverage container 1 according to the embodiment includes a container body 10 and a cover unit 20 mounted on the container body 10. The container body 10 includes a main container body 11 that is cylindrical. For instance, the main container body 11 is of a double-layer structure (for instance, a vacuum-insulated structure) made of stainless steel, which has a closed bottom 11b and a container opening 11h at an upper portion. Further, in the embodiment, one side of the main container body 11 with the container opening 11h is set to be “upper”, and one side of the bottom 11b of the main container body 11 is set to be “lower”. The container body 10 may include a drinking mouth body 12 mounted on the container opening 11h of the main container body 11. In the embodiment, the beverage container 1 having the drinking mouth body 12 is taken as an instance for illustration.
As shown in
The drinking mouth body 12 is embedded in an inner side of an outer annular part 13. When the drinking mouth body 12 is mounted on the container opening 11h of the main container body 11 through screwing, the outer annular part 13 is arranged to cover an outer side of the upper portion of the main container body 11. By means of the outer annular part 13, a screwing part of the drinking mouth body 12 is covered, such that better appearance of the beverage container 1 is ensured. The outer annular part 13 may be separated from the drinking mouth body 12, and for instance, may be separated and washed separately during cleaning. In addition, threads may be preset on an inner circumference of the outer annular part 13. The outer annular part 13 may be screwed by means of threads provided on an outer circumference of the upper portion of the main container body 11, such that the drinking mouth body 12 may be mounted on the main container body 11.
An outer circumference of the lower portion of the drinking mouth body 12 is provided with a first sealing part 15. The first sealing part 15 is made of an elastic member such as organic silicon and elastomer. When the drinking mouth body 12 is mounted on the inner side of the container opening 11h of the main container body 11 through screwing, the first sealing part 15 abuts against a stepped part 11d of the main container body 11, such that airtightness between the drinking mouth body 12 and the main container body 11 is ensured. The drinking mouth body 12 is in a cylindrical shape, the lower portion of the drinking mouth body is provided with a beverage passage hole 121c. A beverage accommodated in the main container body 11 may be discharged out of the container via the beverage passage hole 121c. An inner side of the drinking mouth part 121 provided on the upper portion of the drinking mouth body 12 is provided with a drinking mouth opening 121h. When the drinking mouth body 12 is mounted on the main container body 11, the drinking mouth opening 121h is regarded as the opening of the container body 10.
As shown in
The cover body 21 includes: a cover part 211 covering the drinking mouth opening 121h; and a cover screwing part 212 extending downward in a cylindrical shape from a center of the cover part 211 and mounted on the container body 10 through screwing. An outer circumference of the cover screwing part 212 is provided with a second external thread part 212a. In addition, an inner circumference of a drinking mouth body 12 is provided with a second internal thread part 12b. The cover screwing part 212 is detachably mounted on an inner side of the drinking mouth body 12 by screwing the second external thread part 212a to the second internal thread part 12b.
The cover screwing part 212 is fixed to a back surface of the cover part 211. The cover screwing part 212 may be integrated with the cover body 21. The cover screwing part 212 is screwed to the drinking mouth body 12, and the cover part 211 is mounted to cover an upper portion of the drinking mouth opening 121h. Since the cover screwing part 212 is fixed to the cover part 211, the cover screwing part 212 is rotated while the cover part 211 is rotated, such that the cover screwing part may be assembled and disassembled through screwing.
The cover screwing part 212 is provided in a cylindrical shape having an opening on a lower side. The ventilation pipe 22 is mounted on an inner side (in a cylinder) of the cylindrical cover screwing part 212 in a fitting manner. As shown in
The ventilation pipe 22 is provided with a claw 22b. When the ventilation pipe 22 is embedded in the cylinder of the cover screwing part 212, the claw 22b is engaged with a lug 212c of the cover screwing part 212, such that the ventilation pipe 22 is fitted to the cover screwing part 212. When the ventilation pipe 22 is mounted in the cylinder of the cover screwing part 212 in a fitting manner, the ventilation pipe 22 is mounted to be slightly movable in the vertical direction.
A center of the ventilation pipe 22 is provided with a ventilation path 221 penetrating from an upper end to a lower end. An upper end of the ventilation path 221 is provided with a ventilation hole 221h, and a lower end of the ventilation path 221 is provided with an introduction hole 221c. In the middle of the ventilation path 221, a reducing part 221a having a diameter reduced from bottom to top is provided (with reference to
A lower portion of the outer circumference of the ventilation pipe 22 is provided with a second sealing part 25. When the ventilation pipe 22 is embedded in an inner side of the drinking mouth body 12, the second sealing part 25 ensures airtightness between the ventilation pipe 22 and the drinking mouth body 12.
A top end of the ventilation pipe 22 is provided with the pressure regulating valve 23. The pressure regulating valve 23 is arranged to cover the ventilation hole 221h on the upper end of the ventilation path 221. The pressure regulating valve 23 is made of an elastic member such as organic silicon and elastomer.
The pressure regulating valve 23 is arranged in a capped cylindrical shape. That is, the pressure regulating valve 23 includes: a cylindrical part 231 having an opening on a lower end; and a top 232 blocking an upper end of the cylindrical part 231. The pressure regulating valve 23 in the capped cylindrical shape covers an upper portion of the ventilation pipe 22. In this way, a valve mechanism is formed in which the ventilation hole 221h is blocked with the top 232 of the pressure regulating valve 23.
Preferably, the top 232 of the pressure regulating valve 23 is formed in a curved shape (an approximately hemispherical shape) that is convex downward. In this way, the top 232 in the approximately hemispherical shape may easily make contact with an edge of the ventilation hole 221h without a gap. The top end of the ventilation pipe 22 may be formed into a curved shape (an approximately hemispherical shape) that is concave downward. The top 232 in a convex curved shape abuts against the top end of the ventilation pipe 22 in a concave curved shape, such that airtightness is improved. Since the pressure regulating valve 23 covers the upper portion of the ventilation pipe 22, the pressure regulating valve 23 may be simply assembled and disassembled. Therefore, ease of replacing the pressure regulating valve 23 and maintainability (cleaning, etc.) of the pressure regulating valve 23 are improved.
As shown in
Then, the ventilation pipe unit 220 is assembled on the cover body 21. That is, the ventilation pipe 22 of the ventilation pipe unit 220 is inserted into a cylinder of the cover screwing part 212, and the ventilation pipe 22 is fitted to the cover screwing part 212. In this case, the ventilation pipe 22 is inserted into the cylinder of the cover screwing part 212 by matching a concave part 22a on the ventilation pipe 22 with a convex part 212b on the cover screwing part 212. Then, the ventilation pipe 22 is inserted into a deep portion in the cylinder of the cover screwing part 212, and the claw 22b of the ventilation pipe 22 is hooked to a lug 212c of the cover screwing part 212 (with reference to
As described above, in a cover unit 20 assembled by fitting a ventilation pipe unit 220 to a cover body 21, a pressure regulating valve 23 is arranged between a ventilation pipe 22 and a back surface of a cover part 211. The ventilation pipe 22 is mounted on the cover screwing part 212 in a fitting manner, such that the ventilation pipe is slightly movable in a vertical direction in a cylinder of the cover screwing part 212. That is, since a claw 22b is hooked and fitted to a lug 212c, the ventilation pipe 22 is guided in the vertical direction by matching a convex part 212b with a concave part 22a, so as to be slightly movable in the vertical direction. Therefore, as shown in
In addition, a drinking mouth body 12 is mounted on a container opening 11h of a main container body 11 through screwing. When the cover unit 20 is in a removed state, a beverage may be accommodated in the main container body 11 from a drinking mouth part 121, or poured out from a drinking mouth part 121, or may be drunk by touching a drinking mouth part 121 with a mouth. Since the drinking mouth body 12 is widened from a beverage passage hole 121c to a drinking mouth opening 121h, ease of accommodating or pouring out the beverage and drinking the beverage with the mouth can be obtained. Further, the drinking mouth body 12 is mounted on the main container body 11 through screwing, beverages, ice and other solid objects are easily taken and put by disassembling the drinking mouth body 12 and using the container opening 11h that is wider than the drinking mouth opening 121h.
An inner circumference of the drinking mouth body 12 is provided with a second internal thread part 12b configured to screw the cover screwing part 212. The second internal thread part 12b is formed in a split type having a gap 12c in the middle in a circumferential direction.
As shown in
When the cover unit 20 is screwed to the container body 10, a second sealing part 25 on a lower portion of the ventilation pipe 22 abuts against a stepped part 12d on a lower portion of the drinking mouth body 12, such that airtightness between the ventilation pipe 22 and the drinking mouth body 12 is ensured. In addition, when the second sealing part 25 abuts against the stepped part 12d, the ventilation pipe 22 is prevented from moving downward. In addition, when the cover screwing part 212 is further screwed to the drinking mouth body 12, a lower end of the cover screwing part 212 abuts against a flange part 22c of the ventilation pipe 22. The second sealing part 25 is pressed, such that airtightness between the cover screwing part 212 and the drinking mouth body 12 is improved.
When the cover screwing part 212 is further screwed to the drinking mouth body 12, the pressure regulating valve 23 is pressed in by a back surface of the cover part 211. In this way, a force (a closing force achieved by the pressure regulating valve 23) by which a top 232 of the pressure regulating valve 23 blocks the ventilation hole 221h of the ventilation pipe 22 increases. The cover screwing part 212 is screwed to the drinking mouth body 12 to the extent that flattening of the second sealing part 25 is allowed. In addition, screwing-in of the cover screwing part 212 is limited to the extent that a lower end of an outer circumference of the cover part 211 abuts against an outer annular part 13. Therefore, the second sealing part 25 is not excessively pressed flat. When the cover unit 20 is screwed to the container body 10, airtightness of the container body 10 is ensured by means of a first sealing part 15, the second sealing part 25 and the pressure regulating valve 23.
The cover unit 20 is mounted on the container body 10, and the pressure regulating valve 23 is clamped between the cover part 211 of the cover body 21 and the ventilation pipe 22 through a specified pressing force. Through the pressing force, the pressure regulating valve 23 is in close contact with the ventilation hole 221h, such that sufficient airtightness can be ensured.
When a cover unit 20 is mounted on a container body 10, airtightness of the container body 10 is fully ensured by means of a first sealing part 15, a second sealing part 25 and a pressure regulating valve 23. When internal pressure of a main container body 11 rises for some reasons (with reference to arrow a in the figure), for instance, a reason that a beverage accommodated in the main container body 11 is a carbonate beverage, or a reason related to temperature of a beverage, or a reason related to fermentation, the internal pressure may be transmitted to a ventilation path 221 of a ventilation pipe 22 (with reference to arrow b in the figure).
The internal pressure is transmitted from an introduction hole 221c of the ventilation pipe 22 to the ventilation path 221 and then to a ventilation hole 221h on a top end. When the middle of the ventilation path 221 is provided with a reducing part 221a, a flow rate of air rises at the reducing part 221a and the air is transmitted to the ventilation hole 221h (with reference to arrow c in the figure). When pressure of the air transmitted to the ventilation hole 221h is higher than that for blocking the ventilation hole 221h of the pressure regulating valve 23, the pressure regulating valve 23 is pushed up, such that the ventilation hole 221h is opened (with reference to arrow d in the figure). In this way, a gap is created between the pressure regulating valve 23 and the ventilation hole 221h, from which the air is relieved (with reference to arrow e in the figure).
The air discharged from the ventilation hole 221h passes a gap (with reference to arrow f in the figure) between an outer circumference of the ventilation pipe 22 and a cylindrical part 231 of the pressure regulating valve 23, and further passes a hole 212h (with reference to
In this way, when the internal pressure of the container body 10 exceeds specified pressure, the pressure regulating valve 23 may be automatically opened to discharge the air out of the container body 10 even if the cover unit 20 is in a closed state. The specified pressure for opening the pressure regulating valve 23 may be set according to an elastic modulus of a material of the pressure regulating valve 23, a pressing force required for deformation on the basis of a shape of a top 232 of the pressure regulating valve 23, a shape of a reducing part 221a of the ventilation pipe 22, etc.
When such a valve mechanism for pressure relief of the container body 10 is provided, airtightness of the container body 10 may be not fully ensured. In the embodiment, a rear section of the ventilation path 221 of the ventilation pipe 22 is provided with the pressure regulating valve 23, and the pressure regulating valve 23 is clamped between the cover part 211 and the ventilation pipe 22 through a specified pressing force, such that the pressure regulating valve 23 cannot be opened as long as the internal pressure does not reach a certain level. That is, even if the pressure regulating valve 23 is provided, full airtightness of the container body 10 is easily ensured. For instance, when the container accommodates a carbonate beverage, carbonic acid is likely to escape if the pressure regulating valve 23 is simply opened. In the embodiment, opening pressure of the pressure regulating valve 23 may be preset to be relatively high, such that the carbonic acid may be prevented from escaping, and meanwhile, the internal pressure may be prevented from rising to the extent that the cover unit 20 is difficult to open.
Experiments of the inventor of the present disclosure prove that under the condition that the cover unit 20 is mounted on the container body 10, the pressure regulating valve 23 is not opened until the internal pressure of the container body 10 rises to about 350 kPa, such that airtightness can be ensured.
Herein, the pressure for opening the pressure regulating valve 23 is increased to a certain extent so as to ensure full airtightness of the container body 10, it is possible to open the cover unit 20 without opening the pressure regulating valve 23 while keeping the internal pressure high.
In the embodiment, the ventilation pipe 22 is fitted to the cover screwing part 212 of the cover body 21 in a vertically movable manner. When fitting of the cover body 21 to the container body 10 is loosened, the ventilation pipe 22 may be removed later than the cover body 21 in a vertically movable range. That is, when the cover body 21 is removed from the container body 10, the ventilation pipe 22 is retained at the beginning of loosening. In the state, the cover body 21 is firstly removed.
In this way, a pressing force applied to the pressure regulating valve 23 clamped between the ventilation pipe 22 and the cover part 211 is reduced, and the ventilation hole 221h is opened (the pressure regulating valve 23 is opened) before the second sealing part 25 is opened. As an instance, when the cover unit 20 is opened by rotating by about 160° from a completely closed state, a closed state achieved by the pressure regulating valve 23 is changed to an open state, and pressure may be relieved.
With such a structure, the internal pressure of the container body 10 rises when the cover unit 20 is in a closed state. Before the pressure regulating valve 23 operates, that is, when the cover unit 20 is removed without pressure relief, pressure may be relieved from the ventilation hole 221h before a sealed state achieved by the second sealing part 25 between the ventilation pipe 22 and the drinking mouth body 12 is changed to an open state. Therefore, even if the internal pressure rises in a closed state, when the cover unit 20 is opened before the pressure regulating valve 23 operates, loud noise or drink ejection due to sudden relief of the internal pressure can be suppressed.
In addition, in order to prevent the cover unit 20 from accidentally falling off when the internal pressure of the container body 10 rises, a rotation angle of the cover unit 20 when the cover unit is fastened to the container body 10 through screwing is preferably large. As an instance, in the embodiment, the rotation angle of the cover screwing part 212 when the cover screwing part is fastened to the drinking mouth body 12 through screwing is about 540°.
In addition, when the drinking mouth body 12 is screwed to the main container body 11, a rotation angle of the drinking mouth body 12 when the drinking mouth body is fastened to the main container body 11 through screwing is preferably larger than the rotation angle of the cover unit 20 when the cover unit is fastened to the container body 10 through screwing. As an instance, in the embodiment, the rotation angle of the drinking mouth body 12 when the drinking mouth body is fastened to the main container body 11 through screwing is about 900°.
Further, under the condition that the drinking mouth body 12 is screwed to the main container body 11 and the cover unit 20 is screwed to the drinking mouth body 12, preferably the drinking mouth body 12 is not loosened and only the cover unit 20 is loosened when the cover unit 20 is loosened with hands by means of the cover part 211. For instance, a fastening force achieved through screwing when the drinking mouth body 12 is fastened to the main container body 11 is larger than a fastening force achieved through screwing when the cover unit 20 is fastened to the drinking mouth body 12. In this way, the situation that the drinking mouth body 12 is loosened while the cover unit 20 is loosened can be avoided.
In addition, an inner side of an opening 11h of the main container body 11 is provided with the drinking mouth body 12, and an inner side of the drinking mouth body 12 is provided with the ventilation pipe 22 of the cover body 21, such that a diameter of the second sealing part 25 is made smaller than that of the first sealing part 15. Therefore, friction between the cover body 21 and the drinking mouth body 12 may be smaller than that between the drinking mouth body 12 and the main container body 11, and the cover body 21 may be opened more early than the drinking mouth body 12 when the cover is opened. In this way, ease of opening the cover can be improved, and the container is convenient to use.
In addition, when the cover unit 20 is loosened, the outer annular part 13 is held with one hand and the cover part 211 is rotated and loosened with the other hand. In this case, it is easy loosen only the cover unit 20 while holding the drinking mouth body 12.
In the embodiment, since the ventilation pipe 22 is mounted on the inner side of the cover body 21, the ventilation pipe 22 is removed while the cover body 21 is removed, such that the drinking mouth opening 121h may be opened. That is, when an inner cover of a double-layer cover structure composed of an outer cover and the inner cover is provided with a valve mechanism, if a beverage needs to be poured out, the outer cover needs to be opened and then the inner cover needs to be removed. In the embodiment, since the valve mechanism is arranged on the ventilation pipe 22 that is assembled and disassembled with the cover body 21, the ventilation pipe 22 is removed while the cover body 21 is removed, such that the drinking mouth opening 121h may be opened to allow the beverage to be taken out and put in.
In addition, for instance, when a medium cover is arranged at a position for blocking the container opening 11h of the main container body 11 (near the container opening 11h) and the valve mechanism is arranged on the medium cover, the beverage may easily make contact with the valve mechanism. When an elastic member is used as the valve mechanism, deterioration of the valve mechanism or decrease in durability may be caused by contact between the beverage and the valve mechanism. In the embodiment, since the pressure regulating valve 23 is arranged above the container opening 11h, for instance, on an upper side of the ventilation pipe 22, the pressure regulating valve 23 is kept away from the container opening 11h of the main container body 11. Therefore, contact between the beverage accommodated in the main container body 11 and the pressure regulating valve 23 can be easily avoided, and deterioration of the pressure regulating valve 23 or decrease in durability can be suppressed.
The pressure regulating valve 23 covers the upper portion of the ventilation pipe 22, such that the pressure regulating valve 23 can be assembled and disassembled more easily than the ventilation pipe 22. Therefore, maintainability (cleaning, replacement, etc.) of the pressure regulating valve 23 is improved. In addition, a plurality of individuals made of different materials (individuals having different elastic coefficients), individuals having different wall thicknesses of the top 232, individuals having different shapes of the top 232, etc. of the pressure regulating valve 23 are prepared, such that airtightness of the ventilation hole 221h achieved by the pressure regulating valve 23 or pressure for opening the pressure regulating valve 23 can be easily set through replacement of the pressure regulating valve 23.
An embodiment of the present disclosure may also include the structures shown in the following notes.
A beverage container includes: a container body; and a cover unit mounted on the container body.
The container body includes:
The cover unit includes:
The ventilation pipe has a ventilation path penetrating a center in a vertical direction.
The pressure regulating valve is not fixed to the cover part, and covers an upper portion of the ventilation pipe by blocking a ventilation hole as an upper end of the ventilation path.
When the cover body is screwed to the drinking mouth, the ventilation pipe is clamped between the drinking mouth and the cover part, and the pressure regulating valve subjected to a pressing force from the cover body is elastically deformed to counteract a specified pressing force from the ventilation path so as to seal the ventilation hole.
