Description

  The present invention relates to a fitting for a beverage container that is fixed as a base of a beverage container such as a beer barrel and is connected to a dispense head. More specifically, the gap between the base and an attachment member is eliminated, and foreign matter, rainwater, etc. It is related with the fitting for drink containers which can prevent intrusion of this completely and can reduce maintenance work.

  In a conventional beverage container such as a beer barrel, a base is fixed to the beverage container by welding or the like, and a fitting is screwed into the base. A dispensing head is connected to the fitting. A pressure gas such as carbon dioxide is supplied into the beverage container via the dispense head, and the beverage in the beverage container is poured out of the container. A conventional fitting and the attachment state of the base will be described with reference to FIGS. 17 and 18.

  FIG. 17 is a cross-sectional view from the front showing a state where a conventional fitting is attached to a beverage container. FIG. 18 is an enlarged cross-sectional view showing a fitting and a base portion. In FIG. 17, the beverage is a draft beer and the beverage container is a beer barrel. The fitting mounting member 2 is screwed and fixed inside the base 91 provided at the upper part of the beer barrel 9. A down tube 5 urged upward by a spring is attached to the attachment member 2.

  The gas valve 3 is fixed to the upper end portion of the down tube 5, and the beer valve 4 is urged upward inside the upper end of the down tube 5. The gas valve 3 and the beer valve 4 are closed by an urging force of a coil spring. A dispense head can be attached to the base 91 and the attachment member 2. The dispensing head and the attachment member 2 can be coupled with one touch by a connection mechanism such as a bayonet mechanism by the engagement protrusion 22.

  The dispense head operates the gas valve 3 and the beer valve 4, supplies a pressure gas such as carbon dioxide gas into the beer barrel 9, and increases the internal pressure of the beer barrel 9 so that draft beer is poured out of the container. It is. Draft beer is poured out of the container through the down tube 5 and the beer valve 4. In order to seal gas leakage from between the base 91 and the mounting member 2, a packing 92 is provided between the lower inner surface of the base 91 and the mounting member 2.

  The pop-out preventing member 8 prevents the mounting member 2 from popping out due to the gas pressure in the beer barrel 9 when the mounting member 2 is removed from the base 91. The stopper 81 is brought into contact with the lower surface of the base 91 to prevent popping out. When the gas valve 3 is pushed down by the removal tool, the pressure gas escapes from the inside of the beer barrel 9 and the stopper 81 retracts inside, so that the attachment member 2 can be removed from the base 91.

  In the fitting having such a configuration, although the attachment member 2 is screwed and fixed to the base 91, a minute gap exists between the base 91 and the attachment member 2. Rainwater and draft beer enter from the gap. The sewage that has entered from the gap is prevented from entering the beer barrel 9 by the packing 92, but stays between the base 91 and the mounting member 2 for a long time, which is not preferable in terms of hygiene. When the beer barrel is washed and sterilized at a high temperature, the sewage in the gap boils and ejects, so it can be confirmed that the sewage has accumulated in the gap. When the beer barrel is left in the sun, the sewage in the gap may thermally expand and ooze out of the gap, or may enter the base and contaminate draft beer.

Therefore, the inventor of the present application has proposed a fitting described in Patent Document 1 below. In the fitting of Patent Document 1, in addition to the first sealing member that seals the gap between the lower inner surface of the base and the mounting member, a second sealing member is also provided at the uppermost part of the fitting. This makes it difficult for foreign matter, rainwater, etc. to enter the gap.
JP 2000-79991 A

  In the conventional fittings as shown in FIGS. 17 and 18, foreign matter, dirty water, etc. enter and accumulate between the base 91 and the mounting member 2, which is not preferable in terms of hygiene. Furthermore, since the packing 92 is a flexible material such as rubber, deterioration due to wear or corrosion is unavoidable and needs to be replaced periodically.

  Since this invention is comprised as mentioned above, there exist the following effects.

  Since the attachment portion and the valve seat portion are integrally provided on the base of the beverage container, there is no gap between the top face of the base and the attachment member, and no foreign matter, sewage, or the like enters the gap. As a result, it is possible to reduce the sterilization process of the base part, the work of removing foreign matters, and the like. Further, since the packing replacement work is eliminated and the gas valve replacement work can be easily performed, the maintenance work can be greatly reduced. Furthermore, the number of fitting parts can be reduced and the manufacturing cost of the beverage container can be reduced. In addition, the outer diameter and weight of the base can be reduced while maintaining compatibility with conventional fittings, and the beverage container can be reduced in size and weight.

  In the case where the small diameter portion of the cored bar is constituted by a line segment, the cored bar is easily manufactured and the manufacturing cost can be reduced.

  By configuring the small diameter part of the cored bar with a curve that smoothly continues with the constant diameter part, the small diameter part can be projected outwards while maintaining the short diameter, and the area of the cored bar is increased, and the symmetry of the gas valve And durability can be improved. In addition, when the gas valve is tilted and passed through the central hole of the valve seat, the pushing force for passing the gas valve becomes substantially constant over the entire small diameter portion, and the gas valve can be assembled and removed smoothly. it can.

  Since the marking indicating the direction of the first straight line is provided on the metal core, the inclination direction of the gas valve can be discriminated at a glance, and the workability of the mounting work is greatly improved.

  Since the metal fitting that connects the metal core and the reinforcing metal fitting is integrated with the valve member, the valve member of the gas valve is strongly bonded to the metal core and the metal reinforcing metal fitting, which increases the strength of the gas valve and makes it durable. Improves.

  Since the metal core is integrally formed with the valve member and the reinforcing metal fitting is integrally connected thereto, the strength of the gas valve is increased and the durability is improved. In addition, the gas valve manufacturing process is simple and can be manufactured at low cost.

  In the fitting in which the protective ring is joined to the mounting member having the external thread formed on the outer peripheral side, the fitting of the present invention can be manufactured at low cost by using the mounting member used in the conventional fitting.

  If a gas valve mounting tool is used, the gas valve can be easily assembled to the fitting. Moreover, if a gas valve removal tool is used, a gas valve can be easily removed from a fitting. As a result, the gas valve can be easily attached, removed, and replaced, and the cost for fitting maintenance can be greatly reduced.

  According to the fitting attachment method for a beverage container of the present invention, the fitting of the present invention can be attached by modifying a beverage container to which a conventional base has already been attached. This makes it possible to effectively use the conventional beverage container, significantly reduce the introduction cost of the fitting of the present invention, and enable effective use of resources.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of the fitting of the present invention. The beverage is a draft beer and the beverage container is a beer barrel. In the conventional fitting, as shown in FIGS. 17 and 18, the fitting mounting member 2 is screwed and fixed to the inner periphery of the base 91. However, in the fitting of the present invention, the base and the mounting member are integrated. Yes. A base 93 integrated with the mounting member is connected and fixed to the beer barrel 9 by welding to form a sealed container. A mounting portion 94 is integrally formed on the base 93, and a valve seat portion 95 is formed on the inner peripheral side of the base 93.

  A down tube 5 urged upward by a spring is supported on the mounting portion 94. The gas valve 3 is fixed to the upper end portion of the down tube 5, and the beer valve 4 is urged upward inside the upper end of the down tube 5. The gas valve 3 is biased upward by the coil spring 6 together with the down tube 5, and is pressed against the valve seat 95 on the inner peripheral side of the base 93. The beer valve 4 is pressed against the valve seat portion below the gas valve 3 by the urging force of the coil spring 7. The gas valve 3 and the beer valve 4 are normally closed.

  A dispense head can be attached to the base 93. An engagement protrusion 22 that protrudes inward is provided on the upper inner peripheral side of the base 93, and the dispense head and the base 93 can be coupled with each other by a connection mechanism such as a bayonet mechanism by the engagement protrusion 22. it can. The gas valve 3 and the beer valve 4 are operated by the dispense head, pressure gas such as carbon dioxide gas is supplied into the beer barrel 9, the internal pressure of the beer barrel 9 is increased, and draft beer is placed through the down tube 5 and the beer valve 4. It can be discharged outside.

  The gas valve 3 is formed in an annular shape as a whole, and is arranged so that the central axis is oriented in the vertical direction in use. The gas valve 3 is formed by integrally molding a valve member 32 made of a flexible member such as rubber and a cored bar 31 made of stainless steel or the like. In the conventional gas valve, the outer peripheral edge of the metal core is circular. However, in the present invention, the gas valve 3 needs to be exchanged through the central hole of the valve seat portion 95, so that the shape of the metal core 31 is different from the conventional one. Are different.

  FIG. 2 is a plan view of the gas valve 3 as viewed from above. On the outer peripheral edge of the cored bar 31, flat portions parallel to each other are provided at two positions symmetrical to the center. For this reason, the diameter (short diameter = distance between the flat portions) of the cored bar 31 at the position where the flat portion is provided is smaller than the diameter (major diameter) in the direction orthogonal to this. The portion where the flat portion is provided has a dimension capable of passing through the central hole of the valve seat portion 95. That is, the short diameter dimension of the core metal 31 is smaller than the diameter of the central hole of the valve seat portion 95, and the long diameter dimension of the core metal 31 is larger than the diameter of the central hole of the valve seat portion 95.

  The shape of the cored bar 31 will be described in more detail with reference to FIGS. 3 and 4. FIG. 3 is a plan view showing the shape of the cored bar 31. FIG. 4 is a cross-sectional view of the cored bar 31. 4 is a diagram showing a cross-section taken along the line XX in FIG. The cored bar 31 is formed in an annular shape having a central axis O in the vertical direction. In the conventional cored bar, the contour shape on the outer peripheral side viewed from above (hereinafter referred to as a planar outer peripheral shape) is completely circular. In FIG. 3, a conventional circular contour shape is indicated by a dotted line.

  In the metal core 31 of the present invention, the planar outer peripheral shape is a shape obtained by cutting a part of a circle, and has a shape having a major axis and a minor axis. Here, the major axis direction of the planar outer peripheral shape is defined as a straight line A, and the minor axis direction is defined as a straight line B. The straight line A and the straight line B intersect with the central axis O at one point and are orthogonal to each other. The planar outer peripheral shape of the cored bar 31 is formed by cutting a portion indicated by a dotted line from a circle to form a small diameter portion 312. The small-diameter portion 312 has a shape obtained by cutting a portion outside the two straight lines M and N parallel to the straight line A from the original contour shape (circular shape).

  The straight lines M and N are parallel to the straight line A, and both have a distance of d / 2 from the straight line A. Therefore, the distance (minor axis) between the small diameter portions 312 facing each other is equal to the distance d between the straight lines M and N. A portion other than the small-diameter portion 312 of the planar outer peripheral shape of the cored bar 31 is a constant diameter portion 311 having a constant diameter. The diameter, that is, the major axis of the constant diameter portion 311 is the dimension D shown in the figure. The constant diameter portion 311 has an arc shape. The planar outer peripheral shape of the cored bar 31 is symmetrical with respect to the straight line A and also symmetrical with respect to the straight line B, as shown in FIG. As a typical dimension example of the cored bar 31, the major axis D is 33 mm and the minor axis d is 28 mm. Since the diameter of the central hole of the valve seat 95 is about 31.8 mm, the long diameter D is larger than the diameter of the central hole, and the short diameter d is smaller than the diameter of the central hole.

  On the upper surface of the cored bar 31, a marking 313 indicating the direction of the straight line A (long axis direction) is formed. The stamp 313 is formed as a shallow groove in the straight line A direction at the top of the upper surface of the cored bar 31. Even when the metal core 31 and the valve member 32 are integrally formed to complete the gas valve 3, the stamp 313 is located at a position exposed from the valve member 32. When the gas valve 3 is integrally formed, the rubber material or the like of the valve member 32 flows into the groove of the stamp 313, which becomes a mark with good visibility.

  As will be described in detail later, when the gas valve 3 is attached to the upper end portion of the down tube 5, it is necessary to incline the gas valve 3 in the direction of the straight line A and pass through the central hole of the valve seat portion 95. By providing the marking 313, the straight line A direction of the gas valve 3 (core 31) can be discriminated at a glance, and the workability of the mounting work is remarkably improved. When the stamp 313 is not provided, the straight line A direction of the cored bar 31 cannot be visually recognized from the outside of the gas valve 3, so that workability is deteriorated.

  FIG. 5 is a plan view showing a configuration of a cored bar 31a according to another embodiment. The cored bar 31a is obtained by further improving the planar outer peripheral shape. The planar outer peripheral shape of the cored bar 31a is also a line-symmetric figure with respect to both the straight line A in the major axis direction and the straight line B in the minor axis direction. The lengths of the major axis and the minor axis are the same as those in FIG. 3, and the major axis D is 33 mm and the minor axis d is 28 mm. The minor diameter d is the minimum diameter of the small diameter portion 312a, and is the distance between the intersections of the straight line B and the small diameter portions 312a and 312a.

  In the cored bar 31 shown in FIG. 3, the small-diameter portion 312 is configured with a line segment, but in the cored bar 31a in FIG. 5, the small-diametered portion 312a is configured with a smooth curve. Moreover, the curve which comprises the small diameter part 312a is smoothly connected with the constant diameter part 311 comprised by a circular arc. And the curve which comprises the small diameter part 312a is a curve which protrudes on the outer side rather than the 2 straight lines M and N which are parallel to the straight line A through a minor axis position. In FIG. 5, straight lines M and N are indicated by dotted lines. With respect to the amount of protrusion of the curve, the width e in the straight line B direction of the most protruding portion is 29 mm with respect to the short diameter d of 28 mm. That is, the curves constituting the small-diameter portion 312a protrude outside the straight lines M and N by a maximum of 0.5 mm.

  A marking 313 indicating the direction of the straight line A (long axis direction) is also formed on the upper surface of the cored bar 31a. The inscription 313 has the same configuration as that shown in FIG. 3, and is formed as a shallow groove in the direction of the straight line A at the top of the upper surface of the cored bar 31a. When the gas valve 3 is integrally formed, the rubber material or the like of the valve member 32 flows into the groove of the stamp 313, which becomes a mark with good visibility.

  The reason why the small diameter portion 312a of the cored bar 31a is configured by a curve is as follows. First, as a result of repeating the experiment of inclining the gas valve using the cored bar 31 as shown in FIG. 3 and passing through the central hole of the valve seat portion 95, the pushing force when the central portion of the small diameter portion 312 passes is maximized. It turns out that the pushing force becomes considerably small before and after that. This indicates that the cored bar 31 can be further projected outward except for the short diameter part (intersection part with the straight line B) of the small diameter part 312.

  The planar outer peripheral shape of the cored bar is ideally a conventional circular shape. In the present invention, the cored bar is provided with a small-diameter portion so as to be able to pass through the central hole of the valve seat portion 95. However, the smaller the cut-off area from the circle, the better the symmetry of the gas valve and the durability point. But it is advantageous. As shown in FIG. 5, by configuring the small diameter portion 312a of the cored bar 31a with a curve, the planar outer peripheral shape of the cored bar 31a becomes closer to a circle, and the symmetry and durability of the gas valve are improved. . In addition, when the gas valve using the cored bar 31a is tilted and passed through the central hole of the valve seat 95, the pushing force for passing is almost constant over the entire small-diameter portion 312a, and the gas valve is assembled and removed. Work can also be performed smoothly.

  In addition, as a result of conducting a durability test of the gas valve using the metal core shown in FIGS. 3 and 5, it was confirmed that the conventional durability standard was sufficiently satisfied. Specifically, the following durability tests 1 to 3 were performed on beer barrels incorporating the gas valve of the present invention.

1. Fluctuating and pressurizing the internal pressure of the beer barrel in the range of 0.1 to 3 MPa (1 to 30 atmospheres) was repeated 1000 times.

2. After the internal pressure of the beer keg was set to 450 kPa (4.5 atm), the beer keg was heated to 130 ° C and cooled to 20 ° C by heating and cooling 1000 times.

3. Fluctuating and pressurizing the internal pressure of the beer barrel in the range of 200 to 560 kPa (2 to 5.6 atm) was repeated 5000 times.

Even after any one of the above durability tests 1 to 3 was performed, no abnormality was observed in the appearance of the gas valve of the present invention, and no abnormality was observed in the bonding state between the metal core and the valve member. .

  FIG. 6 is a diagram showing a configuration of a work tool 10 for assembling the gas valve 3 to the fitting of the present invention. Below the work tool 10, there is provided a guide portion 11 that fits into the inner surface of the base 93 and fits into the base 93 and can be fixed to the base 93. The inner surface side of the guide portion 11 has a substantially conical curved surface with a lower inner diameter, and the conical inner surface smoothly guides the gas valve 3 to a predetermined position at the upper end of the down tube 5. .

  The inner surface shape of the guide portion 11 is a substantially conical rotation surface, but the cross-sectional shape thereof is preferably a curve (curved upward curve) rather than a straight line having a constant inclination angle. Although the inclination angle is almost constant at the upper part of the inner surface, there is no problem, but an upward convex curve is suitable so that the inclination angle becomes larger (nearly vertical) as it goes downward, and the inclination becomes vertical in the lowermost part. Such an inner surface shape allows the gas valve 3 to be assembled smoothly without causing damage to the valve member 32.

  Although not shown here, an engagement groove or an engagement hole that can be engaged with the engagement protrusion 22 on the inner surface of the base 93 is provided on the outer periphery of the guide portion 11. The guide portion 11 can be fixed to the base 93 by inserting the guide portion 11 into the base 93 and rotating the guide portion 11 around the vertical central axis by a predetermined angle. This is the same mechanism as fixing the dispensing head to the base 93.

  The guide portion 11 and the base body 13 are fixed to each other by the frame body 12. A moving member 14 is provided to be movable up and down with respect to the base 13. A handle 15 bent in an L shape is rotatably connected to the upper end of the moving member 14. An L-shaped corner of the handle 15 and the base 13 are connected by a connecting member 16. The connecting portion is pivotally supported so as to be relatively rotatable. The moving member 14, the handle 15, and the connecting member 16 constitute a link mechanism, and the moving member 14 can be moved in the vertical direction. The moving member 14 can be moved up and down by rotating the handle 15 left and right as indicated by the arrows.

  An attachment 17 for assembling the gas valve 3 is attached to the lower end of the moving member 14. The fixture 17 can be removed from the moving member 14 and can be exchanged with other tools. The work tool 10 can be used as a tool for removing the gas valve 3 by removing the attachment 17 and attaching the removal tool 18 for removing the gas valve 3 from the fitting.

On the lower end side of the fixture 17, a pressing portion 171 for pushing down the beer valve 4 is provided. A support protrusion 172 and a support plate 173 are provided above the pressing portion 171. The pressing portion 171, the support protrusion 172, and the support plate 173 constitute a support portion that supports the gas valve 3 in an inclined state. The support plate 173 is made of a plate-shaped spring material and elastically supports the gas valve 3 .

  Here, the drive mechanism for moving the moving member 14 of the work tool 10 up and down is described as a link mechanism, but other drive mechanisms may be used. It is also possible to use a rack and pinion mechanism, a hydraulic cylinder, or any other drive mechanism.

  Next, a procedure for assembling the gas valve 3 to the fitting will be described with reference to FIGS. First, as shown in FIG. 7, the guide portion 11 of the work tool 10 is fixed to the base 93 of the beer barrel. Fixing is a simple operation in which the guide portion 11 is inserted into the base 93 and rotated. Then, the handle 15 is rotated to the left horizontal position to move the moving member 14 and the fixture 17 to the upper stroke end, and the gas valve 3 is supported on the fixture 17 in an inclined state of about 45 degrees.

  As shown in the figure, the gas valve 3 is supported in an inclined state of about 45 degrees by the upper surface of the pressing portion 171, the tip of the support protrusion 172, and the support plate 173. At this time, the gas valve 3 is set so that the mark 313 of the gas valve 3 coincides with the direction of the support protrusion 172. As a result, the long axis direction of the cored bar (direction of straight line A, see FIGS. 3 and 5) is inclined by about 45 degrees from the horizontal plane so that the gas valve 3 can pass through the central hole of the valve seat portion 95. become.

  The coil spring 6 and the down tube 5 are inserted into the attachment portion 94 formed integrally with the base 93 through the central hole of the valve seat portion 95 and arranged at a predetermined position as shown in the figure. A coil spring 7 and a beer valve 4 are disposed inside the upper end of the down tube 5.

  Next, as shown in FIG. 8, the handle 15 is rotated clockwise. When the handle 15 is in the upward vertical state, the gas valve 3 supported by the fixture 17 is lowered to the illustrated position. At this time, the gas valve 3 is guided by the conical inner surface of the guide portion 11 and smoothly moves to the upper end position of the down tube 5. The pressing portion 171 at the lower end of the fixture 17 abuts on the beer valve 4 and pushes the beer valve 4 downward against the coil spring 7.

  Further, when the handle 15 is rotated clockwise to reach the right horizontal position, the state shown in FIG. 9 is obtained. The moving member 14 and the fixture 17 reach the lower stroke end. The gas valve 3 passes through the central hole of the valve seat portion 95 and enters the fitting. The gas valve 3 is in contact with the upper end of the down tube 5 and pushes the down tube 5 downward against the coil spring 6.

  Since the down tube 5 has already been pushed down to the lower limit position, the gas valve 3 is pushed back upward. The gas valve 3 is rotated by the force from the upper end of the down tube 5 and the support protrusion 172 so that the gas valve 3 is detached from the support plate 173 that is an elastic member and approaches a horizontal state. And the gas valve 3 will be in the state which can be inserted in the upper end part of the down tube 5. FIG.

  Next, the handle 15 is rotated so as to return in the counterclockwise direction. Since the gas valve 3 is approaching a horizontal state, the gas valve 3 comes into contact with the valve seat 95 when it is raised and becomes horizontal, and the lower small diameter portion of the gas valve 3 is fitted into the upper end of the down tube 5. This state is shown in FIG. The handle 15 is returned to the upper vertical state, and the gas valve 3 is in a state of being fitted in the normal position at the upper end of the down tube 5. The gas valve 3 in the horizontal state cannot pass through the central hole of the valve seat portion 95 and comes into contact with the valve seat portion 95 to achieve the same function as a conventional gas valve.

  As described above, the gas valve 3 can be easily assembled to the fitting using the work tool 10. Even if the base 93, the valve seat portion 95, and the mounting portion 94 are integrally formed, the gas valve 3 can be easily assembled by providing a small diameter portion on the core.

  When the gas valve 3 is used for a long time, the valve member 32 made of a flexible member such as rubber is deteriorated and the function as a valve is impaired. Therefore, it is desirable to remove the gas valve 3 every time it is used for 3 to 6 years and replace it with a new one. The operation of removing the gas valve 3 for replacement can also be easily performed using the work tool 10. Next, a procedure for removing the gas valve 3 from the fitting will be described with reference to FIGS.

  First, as shown in FIG. 11, the removal tool 18 is attached to the lower end of the moving member 14 of the work tool 10. At the lower end of the removal tool 18, a pressing part 181 for pushing down the beer valve 4 is provided. A claw portion 182 protruding in the lateral direction is provided on the upper portion of the pressing portion 181. The lower surface side of the nail | claw part 182 becomes an inclined surface like illustration.

  Next, the guide part 11 of the work tool 10 is fixed to the base 93 of the beer barrel. At this time, it is confirmed that the protruding direction of the claw portion 182 matches the direction of the marking 313 of the gas valve 3. Since the direction of the support protrusion 172 of the fixture 17 and the direction of the claw portion 182 of the detachment tool 18 are the same direction, the marking direction of the gas valve 3 assembled with the work tool 10 is usually the direction of the claw portion 182. Projection direction. However, since the engraving direction may not match as in the case where the gas valve 3 is assembled with another tool, it is desirable that the protruding direction of the claw portion 182 can be changed.

  Then, the handle 15 is rotated to the right horizontal position, and the moving member 14 and the removal tool 18 are lowered to the lower stroke end. During this downward movement, the claw portion 182 of the removal tool 18 comes into contact with the gas valve 3, but since the lower surface of the claw portion 182 is an inclined surface, a lateral force acts on the removal tool 18 to remove it. The outer tool 18 is elastically deformed in the lateral direction and can be lowered until the claw portion 182 reaches the lower surface of the gas valve 3.

  Next, as shown in FIG. 12, the handle 15 is rotated to the left horizontal position, and the moving member 14 and the removal tool 18 are raised to the upper stroke end. The claw portion 182 engages with the lower surface of the gas valve 3, removes the gas valve 3 from the upper end portion of the down tube 5, and further tilts the gas valve 3 upward. Since the claw portion 182 raises the long axis direction indicated by the stamp 313 to incline the long axis of the cored bar, the gas valve 3 can pass through the central hole of the valve seat portion 95. Then, the gas valve 3 can be completely removed from the fitting as shown.

  In order to assemble the new gas valve 3 to the fitting, as described above, the operation may be performed according to the procedure shown in FIGS. As described above, by using the work tool 10, the work of attaching, removing, and replacing the gas valve 3 can be easily performed. In the fitting of the present invention, only the gas valve 3 requires maintenance work such as replacement, and the replacement work of the gas valve 3 can be easily performed, so that the cost for maintenance work can be greatly reduced. Can do.

  Next, a procedure for remodeling the beer barrel 9 provided with the conventional fitting as shown in FIGS. 17 and 18 and attaching the fitting of the present invention will be described. FIG. 13 and FIG. 14 show the procedure. First, the attachment member 2, the down tube 5, the gas valve 3, the beer valve 4 and the coil spring are removed from the base 91 of the conventional beer barrel 9 as shown in FIG. 18, and the packing 92 is also removed. The base 91 is cut from the connection portion with the beer barrel 9 at a predetermined height, and is cut into a shape as shown in FIG.

  And the connection part vicinity with the beer barrel 9 of the nozzle | cap | die 93 of the fitting of this invention is cut off in step shape, and it is set as the shape which fits the nozzle | cap | die 91 remainder of FIG. The remodeling base 93 may have a connecting portion formed in a step shape from the beginning. As shown in FIG. 14, the base 93 is brought into close contact with the rest of the base 91 and fitted, and the outer periphery of the joint is sealed and fixed by welding as indicated by a welded portion 93a. The fitting parts may be assembled to the base 93.

  As described above, since the fitting of the present invention can be attached by effectively using the beer barrel to which the conventional fitting is attached, the cost of introducing the fitting of the present invention can be greatly reduced and the effective use of resources can be reduced. It becomes possible.

  Next, a second embodiment of the fitting according to the present invention will be described. FIG. 15 is a diagram showing a configuration of a base 96 for fitting according to the second embodiment. The base 96 is joined to the beer barrel 9 by welding or the like. The joint is designed to be airtight / liquidtight. The base 96 has an inner surface structure equivalent to that of the base 93 of FIG. 1, and the dimensions and arrangement of the engaging protrusions and valve seats are the same. The mounting portion 94 is also functionally equivalent although the shape of the window is different. In the base 96, the shape on the outer peripheral side is formed to have a small diameter as a whole, and is smaller and lighter than the base 93.

  Since the structure on the inner surface side of the base 96 is equivalent to the base 93, other parts of the fitting (down tube 5, gas valve 3, beer valve 4, etc.) can be assembled in the same manner as the base 93. Further, the beer filling machine, the barrel washing machine, the beer dispensing device (dispensing head, etc.) used for the beer barrel shown in FIG. 18 can be used as it is for the beer barrel provided with the base 96.

  The fitting using the base 96 is small and light, and is suitable for a relatively small-capacity beer barrel. When the fitting of this second form is used, the entire beer barrel can be made small and light, and the transportation cost can be reduced and the storage space can be reduced. It is also possible to downsize the beer barrel and store the beer barrel in the refrigerator for cooling.

  Next, a procedure for manufacturing an equivalent of the fitting of the second embodiment using the conventional fitting mounting member 2 will be described. Since the fitting member 2 of the conventional fitting as shown in FIG. 18 is similar in structure to the aforementioned base 96, it can be used as an equivalent product to the base 96. The structure on the inner surface side of the mounting member 2 is the same as that of the base 96, and the dimensions and arrangement of the engaging projections and the valve seat are the same. As shown in FIG. 16, the attachment member 2 is directly joined to the beer barrel 9 by welding or the like. The joining portion 2a is made to be in an airtight / liquid tight state.

  However, since a male screw portion is formed on the outer periphery of the upper portion of the mounting member 2, the protective ring 21 is screwed into the male screw portion to make the outer peripheral surface flat. A welded portion 21a by spot welding or the like is formed at the connection portion between the protective ring 21 and the mounting member 2, and is joined and fixed so that the protective ring 21 does not come off. In this way, the mounting member 2 can be used almost equivalently to the base 96. Other parts of the fitting (down tube 5, gas valve 3, beer valve 4, etc.) can be assembled in the same manner as the base 93.

  As described above, since the fitting member 2 of the present invention can be used effectively by using the fitting member 2 of the conventional fitting, the cost of introducing the fitting of the present invention can be greatly reduced, and resources can be effectively used. .

  Next, a gas valve according to another embodiment will be described. FIG. 19 is a plan view showing a configuration of a gas valve 3a according to another embodiment. 20 is a cross-sectional view of the gas valve 3a as viewed in the direction of arrows YY in FIG. 21 is a cross-sectional view of the gas valve 3a taken along the line ZZ in FIG. 20 is a cross-sectional view taken along a plane including the long axis of the cored bar 33a, and FIG. 21 is a cross-sectional view cut along a plane including the short axis of the cored bar 33a.

  The gas valve 3a is different from the gas valve 3 shown in FIG. The metal cores 31 and 31a (see FIGS. 3 to 5) of the gas valve 3 are formed of a single member, but in this gas valve 3a, a reinforcing metal fitting 34a is integrally formed in addition to the metal core 33a. .

  The planar outer peripheral shape (outer peripheral contour shape) of the cored bar 33a is the same as the planar outer peripheral shape of the cored bar 31a shown in FIG. The planar outer peripheral shape of the cored bar 33a has the same axis of symmetry as that of the planar outer peripheral shape of the cored bar 31a, and has the same constant diameter portion and small diameter portion. The small-diameter portion is composed of a smooth curve. The inner peripheral side of the cored bar 33a is formed in a circular shape. The cored bar 33a is formed in a shape closer to a plane than the cored bar 31a. The cored bar 33a is provided with a plurality of small-diameter communication holes 331 penetrating the upper surface side and the lower surface side.

  The reinforcing metal fitting 34a is formed in a circular shape as shown in the figure on the outer peripheral side, and is configured in a rotationally symmetric annular shape. However, a marking 341 indicating the long axis direction of the cored bar 33a is formed on the top surface of the reinforcing metal fitting 34a. The stamp 341 is formed as a shallow groove, and when the gas valve 3a is integrally formed, the rubber material or the like of the valve member 32 flows into the groove of the stamp 341 and becomes a mark with good visibility.

  The cored bar 33a and the reinforcing metal fitting 34a are combined and integrally connected as shown in FIGS. At this time, the reinforcing metal fitting 34a is combined so that the marking 341 is in the long axis direction of the cored bar 33a. The lower end portion on the inner peripheral side of the reinforcing metal fitting 34a is formed in a vertical direction before connection, but the core metal 33a and the reinforcing metal fitting 34a are combined, and the lower end portion on the inner peripheral side of the reinforcing metal fitting 34a is outside as shown in the figure. Press to spread. In this way, by expanding the diameter of the inner peripheral side lower end portion of the reinforcing metal fitting 34a, the reinforcing metal fitting 34a is integrally connected to the inner peripheral portion of the core metal 33a.

  The metal valve 33a is manufactured by integrally molding the metal core 33a and the reinforcing metal fitting 34a integrally connected to the valve member 32 made of a flexible member such as rubber. The metal core 33a and the reinforcing metal fitting 34a are made of stainless steel or the like. For example, a press-molded product made of a stainless steel plate having a thickness of 1.5 mm can be used as the core metal 33a, and a press-molded product made of a stainless steel plate having a thickness of 1.0 mm can be used as the reinforcing metal fitting 34a. When the metal core 33a and the reinforcing metal fitting 34a are integrally formed with the valve member 32, the valve member 32 such as a rubber material flows through the communication hole 331, so that the space between the metal core 33a and the reinforcing metal fitting 34a is inserted. The valve member 32 is filled without any gap.

  Such a gas valve 3a can be assembled to the fitting in the same manner as the gas valve 3 shown in FIG. 2 using the work tool 10, and can be removed and replaced in exactly the same manner. In the gas valve 3a, the metal core 33a and the reinforcing metal fitting 34a are integrally formed with the valve member 32, and the valve member 32 is strongly bonded to the metal core 33a and the reinforcing metal fitting 34a. Increases durability and durability.

  FIG. 22 is a cross-sectional view showing a configuration of a gas valve 3b according to another embodiment. The gas valve 3b has a configuration similar to that of the gas valve 3a, but the shape of the reinforcing metal fitting 34b is different and the manufacturing method is different from that of the gas valve 3a. In the gas valve 3b, the cored bar 33b and the valve member 32 are first formed integrally. The configuration of the cored bar 33b is substantially the same as the cored bar 33a. However, no communication hole is provided in the cored bar 33b. The planar outer peripheral shape of the cored bar 33b has the same axis of symmetry as that of the planar outer peripheral shape of the cored bar 31a, and has the same constant diameter portion and small diameter portion. The small-diameter portion is composed of a smooth curve.

  Similar to the reinforcing bracket 34a, a mark indicating the major axis direction of the cored bar 33b is also formed on the top of the upper surface of the reinforcing bracket 34b, but this stamp is not shown in FIG. A reinforcing metal fitting 34b is inserted from above into a central hole of a molded product obtained by integrally molding the metal core 33b and the valve member 32, and integrally connected as illustrated. At this time, the reinforcing metal fitting 34b is inserted so that the marking direction is the long axis direction of the cored bar 33b.

  As shown in the figure, the reinforcing metal fitting 34b has a shape that covers the inner peripheral side portion of the upper surface from the inner peripheral surface of the gas valve 3b. The lower end portion on the inner peripheral side of the reinforcing bracket 34b is formed in the vertical direction before connection, but the lower end portion on the inner peripheral side of the reinforcing bracket 34b is pushed outward as shown in the figure. In this way, by expanding the diameter of the lower end on the inner peripheral side of the reinforcing metal fitting 34b, the reinforcing metal fitting 34b is integrally connected to the inner peripheral part of the metal core 33b, and the valve member 32, the metal core 33b, and the reinforcing metal fitting 34b are integrated. Gas valve 3b.

  Such a gas valve 3b can be assembled to the fitting in the same manner as the gas valve 3 shown in FIG. 2 using the work tool 10, and can be removed and replaced in exactly the same manner. In the gas valve 3b, a metal core 33b and a reinforcing metal fitting 34b are formed integrally with the valve member 32, and the strength of the gas valve is increased and the durability is improved. The gas valve 3b has a simpler manufacturing process than the gas valve 3a and can be manufactured at a low cost. However, the gas valve 3a is superior to the gas valve 3b in terms of strength and durability of the gas valve.

  As described above, according to the present invention, since the mounting portion and the valve seat portion are integrally provided in the base of the beer barrel, there is no gap between the top surface of the base and the mounting member, and foreign matter, sewage, etc. in the gap No intrusion occurs. As a result, it is possible to reduce the sterilization process of the base part, the work of removing foreign matters, and the like. Further, since the packing replacement work is eliminated and the gas valve replacement work can be easily performed, the maintenance work can be greatly reduced. Furthermore, the number of fitting parts can be reduced and the manufacturing cost of the beer barrel can be reduced. In addition, the outer diameter and weight of the base can be reduced while maintaining compatibility with conventional fittings, and the beer barrel can be made smaller and lighter.

  In the above embodiments, draft beer is used as a beverage and a beer barrel is used as a beverage container. However, the present invention can be applied to any other beverage and beverage container.

  According to the present invention, since there is no gap between the base and the attachment member, it is possible to provide a beverage container fitting that is hygienic and excellent at a low cost without causing intrusion of foreign matter or sewage. Moreover, the maintenance work of the beverage container fitting can be greatly reduced.
