Description

  The present invention relates to a beverage dispensing mechanism and a dispensing method provided in a can filled with a beer-taste beverage.

  Conventionally, various attempts have been made to pour out beer-taste beverages, and when providing beverages at restaurants, etc., it is possible to pour out fine bubbles by pouring out beverages at a beverage server. . However, when beer-taste beverages are poured out at home or the like, the beverage server is large, and it is often difficult to place it, and it is difficult to maintain and costs and time. For this reason, beverage servers are rarely used at home, and beer-taste beverages are often poured from cans into glasses. For this reason, there is a present situation that fine bubbles cannot be poured out.

  Japanese Patent Application Laid-Open No. 2004-168417 describes a beverage dispensing structure provided with a pull tab for opening a beverage can. The pull tab is rotatably supported on the shaft located on the top surface of the beverage can. This pull tab has a grid-like or mesh-like through-hole in a handle portion located at a location away from the saddle shaft. The pull tab is formed with a plurality of linear through holes partitioned from each other. In the above-described pouring structure, the pull tab is rotated to block a part of the opening of the beverage can with the handle, and in this state, the beer-taste beverage is passed through the through hole, thereby changing the foam shape. .

JP 2004-168417 A

  Generally, the size of the pull tab is about several centimeters and is very small. In the above-described pouring structure, a plurality of linear through holes partitioned from each other are formed in the pull tab, so that the size of each through hole is very small. Further, since the pull tab is manufactured by cutting a metal plate, it is difficult to form such a very small through hole. That is, in order to form the above-mentioned through hole, a plurality of very small cutting blades must be prepared. Therefore, there exists a problem that workability of manufacture of a pull tab is not good.

  An object of the present invention is to provide an extraction mechanism and an extraction method capable of extracting fine bubbles and improving workability.

  The dispensing mechanism according to one aspect of the present invention is formed on the top surface by pulling up the hook portion that is attached to the top surface of the can filled with the beer-taste beverage and having a hook portion on which the finger is hooked. The beverage dispensing mechanism includes an opening forming portion that is cut along a cutting line and enters the inside of the can to form an opening in the top surface, and is provided in advance in the opening, and the opening is formed in the top surface And a sheet member that closes a part of the opening in the formed state.

  In this pouring mechanism, an opening is formed in the top surface so that the opening forming portion enters the inside of the can and pours the beverage by hooking a finger on the hooking portion of the pull tab and pulling up the hooking portion. The dispensing mechanism includes a sheet member that pulls up the hook portion and closes a part of the opening in a state where the opening is formed on the top surface. Therefore, when pouring a beer-taste beverage into a glass or the like, fine bubbles can be poured by passing the beer-taste beverage through an opening that is partially blocked. Therefore, fine bubbles of a beer-taste beverage can be easily poured out even at homes that do not have a beverage server. In this dispensing mechanism, a sheet member is provided in advance before the beer-taste beverage is dispensed, and the operation of rotating the pull tab described above is unnecessary, so fine bubbles can be easily poured simply by pulling up and pouring the pull tab. Can be issued. In this pouring mechanism, it is only necessary to attach a sheet member in advance, and there is no need to specially process the pull tab. Therefore, the workability of manufacturing the pull tab can be improved. Furthermore, since a part of the opening is closed with the sheet member, the shape of the part that closes the part of the opening can be simplified, and the part can be configured not to protrude from the can.

  Further, the sheet member may have a through hole that penetrates the sheet member at a position overlapping the opening. In this case, the beer-taste beverage is poured out through the through hole formed in the sheet member. Therefore, the shape of the bubble to be poured out can be changed according to the shape of the through hole, and more finely bubbled can be poured out.

  Further, the sheet member may be constituted by a tape having water resistance. In this case, since the sheet member can be easily attached to the top surface, the workability can be further improved. Furthermore, when fine foam is unnecessary, the sheet member can be peeled off from the top surface, and therefore, it is possible to provide a beer-taste beverage according to the taste of the drinker.

  The sheet member may have a plurality of through holes, and each through hole may be linear. In this case, since the beer-taste beverage is poured out through each through-hole formed in a straight line, finer foam can be poured out into a glass or the like.

  The sheet member may have a plurality of through holes, and each through hole may have a circular shape. In this case, when the beer-taste beverage is poured into a glass or the like, the beer-taste beverage is poured out through the circular through holes, so that fine bubbles can be poured out.

  A pouring method according to the present invention includes the pouring mechanism described above, and is a pouring method for pouring a beverage from a can filled with a beer-taste beverage. A step of forming an opening on the top surface by allowing the sheet to enter the inside and closing a part of the opening with the sheet member is provided.

  In this pouring method, by pulling up the hooking portion and allowing the opening forming portion to enter the inside of the can, the opening can be formed on the top surface, and a part of the opening can be closed with the sheet member. Therefore, by passing the beer-taste beverage through the partially blocked opening, fine bubbles of the beer-taste beverage can be poured out even in a home that does not have a beverage server. Moreover, since the sheet | seat member is previously provided before pouring out a beer taste drink, fine foam can be easily poured out only by pulling up and pulling a pull tab.

  According to the present invention, fine bubbles can be poured out and workability can be improved.

  Hereinafter, embodiments of a dispensing mechanism and a dispensing method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and repeated description is omitted as appropriate.

(First embodiment)
FIG. 1 is a perspective view showing a can 1 provided with a dispensing mechanism 10 according to the first embodiment. As shown in FIG. 1, for example, the can 1 has a cylindrical appearance. The can 1 includes a circular bottom, a cylindrical body 2 standing upright from an outer edge of the bottom, and a circular lid 3 positioned at the upper end of the body 2. The trunk | drum 2 has the diameter reducing part 2a which diameter-reduces gradually toward the upper end part as it goes upwards.

  The can 1 is filled with a beer-taste beverage. Here, the beer-taste beverage includes a beverage that has a taste like beer and a beverage that gives a drinker a sense of drinking beer. In addition, beer-taste beverages are beverages having an alcohol content of less than 1% (also expressed as “volume / volume (%)” or “v / v (%)”), and beverages having an alcohol content of 1% or more. Including. A beverage having an alcohol content of 1% or more is also referred to as a beer-taste alcoholic beverage.

  Furthermore, beer-taste beverages include malt fermented beverages such as beer, malt liquor, and liqueur (for example, beverages classified as “liqueur (foamable) (1)” under the liquor tax law) using malt as a raw material, and It also includes beer-taste fermented beverages that do not use wheat or malt as a raw material (for example, beverages classified as “other brewed liquors (effervescent) (1)” under the liquor tax law).

  In the present embodiment, for example, the can 1 may be filled with beer. Beer is an alcoholic beverage with an alcohol content of less than 20%, fermented using malt, hops and water as raw materials, or malt, hops, water, wheat and other items specified by the Ordinance for the Enforcement of the Liquor Tax Law. Fermented as a raw material (the total weight of articles specified in the Ordinance for Enforcement of the Liquor Tax Law does not exceed 50% of the weight of malt), and the malt ratio (malt use ratio) of the fermented raw material Including 67% by mass or more.

  The lid 3 of the can 1 has a circular top surface 4 that is directed vertically upward, a circular rising portion 5 that rises from the outer edge of the top surface 4, and a dispensing mechanism 10 that pours beer-taste beverages. . By having the rising portion 5, the top surface 4 is recessed from the upper end of the can 1. Since the rising portion 5 has a shape in which the metal plate is curved in an inverted U shape, even if a drinker touches the rising portion 5, injuries and the like are suppressed.

  FIG. 2 is a plan view showing the lid 3 with the can 1 opened. As shown in FIGS. 1 and 2, the dispensing mechanism 10 is provided inside a recess 6 formed on the top surface 4. The recess 6 has a shape extending long from one side (upper side in FIG. 2) of the top surface 4 in the radial direction to the other side (lower side in FIG. 2). It gradually spreads from one side to the other. A pair of circular convex portions 7 are formed in the inner portion of the concave portion 6 near the center of the top surface 4. In addition, an inclined surface 8 is formed on the outer edge of the recess 6 that gradually increases from the recess 6 toward the radially outer side of the top surface 4.

  The dispensing mechanism 10 is a mechanism for pouring a beer-taste beverage filled in the can 1 into a container (such as a glass) located outside the can 1. The dispensing mechanism 10 includes a circular support member 11 attached to the recess 6, a pull tab 12 supported by the support member 11, and an opening 13 that expands and curves in a U shape outside the support member 11 in the radial direction. And an opening forming portion 14 for forming a sheet member 16 and a sheet member 16 for closing a part of the opening 13. The support member 11 is attached to the center of the top surface 4, for example.

  The pull tab 12 includes a first portion 12 a that extends from the support member 11 to the outside in the radial direction of the top surface 4, and a second portion 12 b that extends from the support member 11 to the outside in the radial direction of the top surface 4. The pull tab 12 has a shape extending long from the first portion 12a toward the second portion 12b. Since the pull tab 12 is rounded on the entire outer periphery thereof, it is possible to avoid a situation where the pull tab 12 is touched and the finger is cut.

  The pull tab 12 has, on the second portion 12b side, a U-shaped opening 12c surrounding the support member 11, and a recessed portion 12h recessed downward. The recess 12h is formed on the end side in the longitudinal direction (vertical direction in FIG. 2) of the pull tab 12 with respect to the opening 12c. The recess 12 h protrudes downward from the outer edge of the pull tab 12. The concave portion 12h corresponds to a portion that pushes down the opening forming portion 14 when the hooking portion 12f of the pull tab 12 is pulled up. The recess 12h has an elliptical shape.

  The pull tab 12 has a hooking portion 12 f at a position on the first portion 12 a side that is separated from the support member 11. When a finger is put under the hooking part 12f and the hooking part 12f is pulled up by the finger, the opening forming part 14 enters the inside of the can 1 and the opening 13 is formed. The hook 12f has one through hole 12g that passes through the hook 12f. The through hole 12g has an oval shape extending in the width direction of the pull tab 12. Thus, by putting a finger under the hooking portion 12f in which the through hole 12g is formed, it is possible to put the finger easily.

  The opening forming portion 14 is integrated with the top surface 4 (recessed portion 6) and the cutting line 15 before opening the can 1. When the hook 12 f of the pull tab 12 is pulled up and the recess 12 h of the pull tab 12 pushes down the opening forming portion 14, the opening forming portion 14 is cut along the cutting line 15 to form the opening 13.

  The opening forming portion 14 has a bent portion 14a extending linearly in the vicinity of the support member 11, and enters the inside of the can 1 with the bent portion 14a as an axis. The cutting line 15 is formed along the outer periphery of the opening forming portion 14 before the can 1 is opened. The cutting line 15 extends from one end of the bent portion 14a along the outer periphery of the concave portion 6 and extends to the other end of the bent portion 14a. Therefore, the cutting line 15 has a U shape that widens as the distance from the support member 11 increases, and the opening 13 is formed by the cutting line 15 and the bent portion 14a.

  The sheet member 16 is affixed to the top surface 4 in advance before opening the can 1. The sheet member 16 is constituted by a tape having water resistance. The sheet member 16 covers a part of the opening 13, and specifically covers a part of the opening 13 opposite to the support member 11. The sheet member 16 has a rectangular shape, for example.

  The sheet member 16 has a straight portion 16 a that crosses over the opening 13, and covers the opening 13 that is located on the opposite side of the straight portion 16 a to the support member 11. The sheet member 16 has a through hole 16b extending in the crossing direction of the linear portion 16a. The beer-taste beverage filled in the inside of the can 1 is poured through the through hole 16b.

  For example, a plurality of through holes 16b are formed, and the plurality of through holes 16b are arranged at equal intervals. Each through-hole 16b has comprised the rectangular shape extended in the direction orthogonal to the linear part 16a, for example. As an example, the plurality of through holes 16b are arranged, for example, symmetrically in the opening 13, and the number of through holes 16b is five, for example. Of the five through-holes 16b, the lower ends of the through-holes 16b located at the left and right ends (ends opposite to the support member 11) are located below the lower ends of the openings 13. On the other hand, the lower end of the through hole 16 b located at the center of the five through holes 16 b is located above the lower end of the opening 13.

  For example, the sheet member 16 is attached to the top surface 4 so that the straight portion 16 a passes through the vicinity of the center of the opening 13. Thereby, it is possible to pour out a beer-taste beverage from the portion on the support member 11 side of the opening 13 and the through hole 16b while closing the opening 13 by the sheet member 16.

  Next, a beverage dispensing method performed using the dispensing mechanism 10 will be described. First, in the initial state shown in FIG. 1, a finger is put under the hooking portion 12f and the hooking portion 12f is pulled up. By pulling up the hooking portion 12f, the opening forming portion 14 is pushed down by the concave portion 12h, and cutting along the cutting line 15 is performed.

  As shown in FIG. 2, the opening forming portion 14 is bent inside the can 1 through the bent portion 14 a by cutting along the cutting line 15. In this way, by opening the opening forming portion 14 to the inside of the can 1, the opening 13 is formed on the top surface 4, and a part of the opening 13 is blocked by the sheet member 16 (part of the opening is The process of making it a closed state). Then, by pouring a beer-taste beverage from the can 1 in a state where a part of the opening 13 is blocked by the sheet member 16, a beer-taste beverage having fine bubbles in a glass or the like located outside the can 1 is poured out.

  Next, the effect obtained from the extraction mechanism 10 and the extraction method according to the present embodiment will be described in detail.

  In the pouring mechanism 10 and the pouring method according to this embodiment, the opening forming portion 14 enters the inside of the can 1 and pours out the beverage by hooking a finger on the hooking portion 12f of the pull tab 12 and pulling up the hooking portion 12f. An opening 13 is formed in the top surface 4. The dispensing mechanism 10 includes a sheet member 16 that closes a part of the opening 13 in a state where the hooking portion 12f is pulled up and the opening 13 is formed on the top surface 4. Therefore, when pouring a beer-taste beverage into a glass or the like, fine bubbles can be poured out by passing the beer-taste beverage through the partially-opened opening 13.

  Therefore, fine bubbles of a beer-taste beverage can be easily poured out even at homes that do not have a beverage server. In the dispensing mechanism 10, the sheet member 16 is provided in advance before the beer-taste beverage is dispensed, and a special operation for rotating the pull tab 12 or swinging the pull tab 12 is not required. Therefore, fine bubbles can be easily poured out simply by pulling up the pull tab 12 as usual.

  In the dispensing mechanism 10, it is only necessary to attach the sheet member 16 in advance, and it is not necessary to specially process the pull tab 12. Therefore, the workability of manufacturing the pull tab 12 can be improved. Furthermore, since a part of the opening 13 is blocked by the sheet member 16, the shape of the part that covers the part of the opening 13 can be simplified, and the part (the sheet member 16) does not protrude from the can 1. can do.

  Further, the sheet member 16 has a through hole 16 b that penetrates the sheet member 16 at a position overlapping the opening 13. Therefore, the beer-taste beverage is poured out through the through hole 16b formed in the sheet member 16. Therefore, the shape of the bubble to be poured out can be changed according to the shape of the through-hole 16b, so that a finer bubble can be poured out.

  Further, the sheet member 16 is made of, for example, a water-resistant and adhesive tape. Therefore, the sheet member 16 can be easily attached to the top surface 4, so that the workability can be further improved. Furthermore, when fine foam is not required, the sheet member 16 can be peeled off from the top surface 4, so that it is possible to provide a beer-taste beverage according to the taste of the drinker.

  The sheet member 16 has a plurality of through holes 16b, and each through hole 16b is linear. Therefore, since a beer-taste drink is poured out through each through-hole 16b made into linear shape, a finer foam can be poured out to glass etc. FIG.

In the following description, the description overlapping with the first embodiment is omitted as appropriate. As shown in FIG. 3, the dispensing mechanism 20 is different from the first embodiment in that it includes a sheet member 26 having through holes 26 b that are different in number, shape, and arrangement from the through holes 16 b.

  The sheet member 26 includes a plurality of circular through holes 26b. The through hole 26 b includes a plurality of first through holes 26 c located on the support member 11 side and a plurality of second through holes 26 d located on the opposite side of the support member 11. That is, the arrangement of the through holes 26b is a two-stage structure including the first through holes 26c and the second through holes 26d.

  The plurality of first through holes 26c and the plurality of second through holes 26d are both disposed along the longitudinal direction of the sheet member 26 (the left-right direction in FIG. 3), for example, at equal intervals. In the longitudinal direction of the sheet member 26, the first through holes 26c and the second through holes 26d are alternately arranged.

  Further, the shape connecting the two first through holes 26c adjacent to each other and the one second through hole 26d is an equilateral triangle, and the two second through holes 26d adjacent to each other and the first first through hole 26d. The first through hole 26c and the second through hole 26d are arranged so that the shape connecting the through hole 26c is an equilateral triangle. For example, the number of first through holes 26c is four, and the number of second through holes 26d is three.

  As described above, in the pouring mechanism 20 of the second embodiment, like the pouring mechanism 10 of the first embodiment, a part of the opening 13 is blocked in a state where the hook portion 12f is pulled up and the opening 13 is formed on the top surface 4. A sheet member 26 is provided. Therefore, when pouring a beer-taste beverage into a glass or the like, fine bubbles can be poured by passing the beer-taste beverage through the partially-opened opening 13. Therefore, the same effect as the first embodiment can be obtained.
