Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a beverage dispenser capable of dispensing an arbitrary amount of beer, juice, and other beverages.
[0002]
[Prior art]
2. Description of the Related Art Pitchers made of glass or synthetic resin are conventionally known as beverages, for example, those provided as containers for beer in restaurants. The pitcher has a capacity of about 2 to 3 liters and is mainly used when drinking beer in a group of a plurality of people. However, since it has a capacity of about 2 to 3 liters, it has been a considerable burden to lift the beer into each person's glass and mug when the beer is full. Moreover, since the conventional pitcher does not have a cold insulation means, the beer is warmed with the passage of time, and the deterioration of the taste cannot be avoided.
[0003]
As a beverage container for solving such problems, a barrel-shaped outer container having a bottom wall at the bottom and an opening at the top, and a container main body for storing beverages such as beer stored in the barrel-shaped outer container, A lid body that is detachably screwed into the opening of the container body with a twist screw, a cock that is a beverage dispensing tool attached to the lid body, and at least one of the bottom wall or the lid body of the barrel-shaped container body are seen through. A container composed of a see-through window has been proposed in Japanese Patent Application Laid-Open No. 8-230861.
[0004]
According to the barrel-shaped beverage container described in Japanese Patent Application Laid-Open No. 8-230861, after storing the beer and transporting it to the liquor seat, a predetermined amount of beer can be poured out by simply twisting the cock. There is no burden like a pitcher. Moreover, since the container has a double structure of the barrel-shaped outer container and the container main body, it has an effect of being excellent in cold insulation as compared with a conventional pitcher.
[0005]
[Problems to be solved by the invention]
As is well known, a factor affecting the taste of beer is the quality of foam formed on the top of the beer poured into a cup or mug. In other words, the finer the bubbles, the better the beer's original taste.
However, conventionally known barrel-shaped beverage containers, including Japanese Patent Application Laid-Open No. 8-230861, only pour out beer by gravity from a single spout formed in the cock, so that fine bubbles are obtained. I could not. Further, in the conventional cock, when the cock is closed after beer pouring, the inside of the spout becomes airtight, so that beer remains. When the remaining beer is subjected to some kind of impact, the so-called dripping phenomenon, which is dripped from the spout, occurs and the table and clothes are soiled.
[0006]
In addition, in the barrel-shaped beverage container described in JP-A-8-230661, when the beer in the container is drunk, the screwed lid is once opened to replenish the beer, and then the lid is further screwed. become. However, due to the fact that the lid has a considerable size and that beer remains in the threaded portion of the lid, the screwing may be insufficient. Since the barrel-shaped beverage container is placed at the liquor seat so that the lid body having the bottom wall and the cock is in the vertical direction, beer is always in contact with the lid body. Therefore, if the screwing of the lid is insufficient, beer may leak from the gap between the lid and the container body.
Moreover, although the cold insulation property is improved as compared with the conventional pitcher, further improvement of the cold insulation property is required.
[0007]
This invention makes it a subject to provide the drink extraction tool which can form a fine foam when beer is poured from the container for drinks in view of the above problem. Furthermore, this invention makes it a subject to provide the drink extraction tool which can prevent dripping.
Another object of the present invention is to provide a beverage container that is capable of forming fine bubbles and preventing dripping, and that is free from leakage of beer, juice, etc. and has excellent cold insulation properties. .
[0008]
[Means for Solving the Problems]
The present invention is a beverage pouring tool used by being attached to a beverage container, comprising a beverage inlet, a beverage channel communicating with the beverage channel, a main pouring port communicating with the beverage channel, and a main pouring port A dispensing tool main body having a sub-outlet with a small opening diameter, and a valve body capable of sealing the beverage flow path; A spout is arranged, the sub-outlet has a predetermined angle with respect to the main spout, a flow path is formed, and the beverage poured out from the sub-outlet is poured out from the main spout By adopting the technical means of pouring the beverage together with the main pouring outlet so as not to be mixed with the drinks made, it is possible to form fine bubbles.
[0009]
According to the present invention, the main pouring outlet and the sub pouring outlet are arranged in order from the side of the beverage container to be attached, and when the beer pouring flow from the sub pouring outlet reaches the beer in the mug, the mug The beer already poured inside is stimulated, and the carbon dioxide dissolved in the beer forms fine small bubbles by the stimulus.
[0010]
In the present invention, if a slit is formed in the main pouring outlet, an airtight state is not formed in the pouring outlet after the cock is closed and beer pouring is stopped, so that beer does not remain in the main pouring outlet. It is possible to prevent dripping.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention targeting beer as a beverage will be described with reference to the drawings. 1-3 is a figure which shows the drink extraction tool which concerns on this Embodiment, and FIGS. 4-6 is a figure which shows the container for drinks which attached this drink extraction tool.
As shown in FIGS. 4 to 6, the beverage container according to the present embodiment includes a transparent container body 1 made of polycarbonate, an external container 2 made of polypropylene, a heat insulating member 3 made of polystyrene foam, and an opening of the container body 1. The lid 4 attached to the container, the cock (beverage dispensing tool) 5 attached to the container body, and the legs 6 that support the container at the bottom of the outer container 2 are the basic components.
[0012]
The container body 1 includes a bottom wall 10, a side wall 11 erected from the bottom wall 10, a see-through window 12 that constitutes a part of the side wall 11, a grip portion 13 formed on the upper side of the side wall 11, and a lower part of the side wall 11. It is comprised from the latching protrusion 14 which protrudes toward an outer periphery, and since it is the product made from a polycarbonate as mentioned above, the whole is transparent. The material of the container body 1 may be made of a transparent material such as acrylic resin, PET (polyethylene terephthalate), styrene resin, and in some cases, a glassy material may be used. it can.
As shown in FIG. 5, the bottom wall 10 has a slope that descends toward the cock 5 arrangement side. Therefore, even when the beverage such as beer is reduced, the beverage effectively flows into the cock 5 and is prevented from remaining in the container body 1.
[0013]
The side wall 11a on the non-mounting side of the cock 5 and the bottom wall 10 intersect at an obtuse angle in combination with the inclination of the bottom wall 10 as described above (see FIG. 5). With this structure, foaming when beer is poured into the container body 1 is prevented. That is, when the container body 1 in which the side wall 11 and the bottom wall 10 intersect at a right angle is used and beer is poured along the side wall 11a, the foaming of the beer becomes intense when the intersection is a right angle. It has been found that beer foaming is prevented when the intersection is obtuse as in the embodiment. Particularly in the case of the present embodiment, since the rounds are further formed at the intersecting portion, the foaming prevention effect is more remarkable.
[0014]
Steps 14 a and 14 b are formed at the upper end of the side wall 11, and the lid 4 is positioned at a predetermined position by the steps 14 a and 14 b. A cock mounting hole for mounting the cock 5 is formed below the see-through window 12 on the side wall 11.
The see-through window 12 is for confirming the remaining amount of the beverage in the container main body 1, and this portion faces the outside of the beverage container when the container main body 1 is stored in the external container 2.
[0015]
In the present embodiment, the see-through window 12 is continuously provided in almost the entire longitudinal direction of the side wall 11, but various forms such as being provided only at the lower part of the container body 1 or intermittently are conceivable. In addition, the width can be arbitrarily set, and in the present embodiment, the width of the cock 5 is made to coincide with the width of the cock 5 in order to produce a design effect. However, the width can be narrower or wider than this. Moreover, although it is desirable that the position of the see-through window 12 is formed in the upper part of the cock 5, it may be in another place.
The gripping portion 13 is formed with four gripping holes 13a at equal intervals, and can be transported using the gripping holes 13a at appropriate locations.
[0016]
The outer container 2 is made of polypropylene having a thin hollow cylindrical shape, and includes a container main body storage portion 20 that covers almost the entire area of the outer container 2, a transparent window arrangement slit 21 in which the transparent window 12 of the container main body 1 is disposed, A leg arrangement surface 22 formed at the lower end of the container 2 and a design protrusion 23 formed at a predetermined interval on the outer peripheral part of the outer container 2. As can be understood from the figure, the overall appearance of the outer container 2 is conscious of a metal container that contains draft beer at a restaurant, and although not shown in the figure, the brand of beverage such as beer that is contained, A pattern can be applied. The outer container 2 may be made of a resin such as polyethylene or PET, or a material such as metal, wood or cardboard.
[0017]
The container main body storage portion 20 has an inner diameter larger than the outer diameter of the container main body 1, and forms a gap sufficient to arrange the heat insulating member 3 when the container main body 1 is stored.
The see-through window arrangement slit 21 has a length corresponding to the see-through window 12 of the container body 1 from the upper end portion of the outer container 2, and supports the lower end portion of the see-through window 12 at the lower end edge thereof. As shown in FIG. 5, the see-through window 12 faces the outside of the beverage container in the see-through window arrangement slit 21, and the remaining amount of the drink in the container body 1 can be confirmed from the outside.
A locking projection 24 is formed on the outer periphery of the lower end portion of the outer container 2. By lifting the container body 1 by the engagement relationship between the locking projection 24 and the locking projection 14 of the container body 1, the outer container 2 The whole container including can be lifted integrally.
[0018]
The heat insulating member 3 is made of foamed polystyrene, and is disposed in a gap formed between the container body 1 and the outer container 2. In this embodiment, the heat insulating member is divided into three parts from the viewpoint of handling convenience, but may be formed integrally. Moreover, in this Embodiment, although the heat insulation member is installed in the whole outer peripheral surface of the container main body 1 except the part of the see-through window 12 without a space | gap, it can also install with an appropriate space | interval. However, it goes without saying that it is desirable to provide it on the entire outer peripheral surface for cold insulation. Furthermore, in this Embodiment, although the polystyrene foam is used from a cost, the heat insulation effect, and a lightweight viewpoint as the heat insulation member 3, the material which has another heat insulation effect can be used. In addition, a pack-like cryogen can also be used.
[0019]
The lid body 4 is made of polycarbonate. A positioning projection 42 is provided on the outer periphery of the substantially central portion of the side wall 41, and a packing storage groove 44 for storing a ring-shaped packing 43 having a U-shaped cross section on the lower outer periphery. Is formed. Further, a gas vent hole 45 is formed in the center of the top of the lid 4. The lid 4 having the above configuration is mounted at an appropriate position by the positioning projections 42 of the side wall 41 and the bottom edge of the side wall 41 abutting against the step 14a and the step 14b of the container body 1 respectively. The packing 43 is made of silicone rubber, and is pressed against the container body 1 with such a force that the beverage does not leak even when the container body 1 is inclined and the liquid level of the beverage exceeds the bottom edge of the lid 4. The packing 43 has a U-shaped cross section, and since the contact with the container body 1 is performed at two points, the effect of preventing the beverage from leaking to the outside is high. The degassing hole 45 is for releasing the gas sequentially emitted from the beverage to the outside of the container when storing a carbonated beverage such as beer. Furthermore, a gripping means 46 is formed on the upper surface of the lid body 4 for facilitating attachment / detachment to / from the container body 1.
[0020]
The lid 4 is preferably made of polycarbonate, but may be other transparent materials such as acrylic resin, PET, styrene resin, etc., and non-transparent made of metal, wood, paper, plastic, etc. It may be a material.
[0021]
The details of the cock 5 will be described with reference to FIG. 1 showing its longitudinal section and FIG. 2 showing its exploded perspective view.
As shown in FIGS. 1 and 2, the cock 5 includes a cock body 51, a valve body 52, a packing 53, a lid body 54, a coil spring 55, a lever 56, and an O-ring 57.
[0022]
The cock body 51 made of a synthetic resin such as polypropylene or nylon has a beer inlet (beverage inlet) 510, a beer passage (beverage passage) 511, a valve body storage portion 512, a main pouring outlet 513, and a side note. An outlet 514 is formed, and the beer stored in the container body 1 passes through the cock body 51 and is poured out in this order. On the outer periphery of the beer inlet 510, a screw 515 is engraved to be screwed into and fixed to the cock set screw 58 fixed to the cock mounting hole of the container body 1, and the upper end outer periphery of the valve body storage unit 512 is engraved. Are engraved with screws 516 for screwing with the lid 54.
[0023]
The main outlet 513 is formed in the vertical direction, and the auxiliary outlet 514 is formed with a predetermined angle from the vertical direction. Therefore, the beer poured out from the main pouring outlet 513 and the sub pouring outlet 514 does not mix with each other. The main outlet 513 and the secondary outlet 514 are arranged in this order from the container body 1 side.
[0024]
The opening end of the main pouring outlet 513 is inclined with respect to the horizontal direction. This is because if the open end is open in the horizontal direction, the beer flow poured out from the end tends to be disturbed, whereas if it is inclined, the beer flow is less likely to be disturbed. Further, a slit 513a for preventing dripping is formed in the main pouring outlet 513.
[0025]
A reservoir 514 a having a diameter larger than the diameter of the sub-outlet 514 is formed in the upstream portion of the sub-outlet 514. Due to the presence of the storage portion 514a, beer can be poured out from the sub-outlet 514 vigorously. If the momentum of the beer flowing out from the sub-outlet 514 is weak, fine bubbles cannot be formed as will be described later.
[0026]
The valve body 52 made of a synthetic resin such as polypropylene or nylon has a substantially cylindrical shape, a flange 521 for fixing the packing 53 at one end, and a lever 56 at the other end. A locking groove 522 is formed for possible locking.
[0027]
The packing 53 made of silicone rubber has a substantially top hat shape, and is integrated with the valve body 52 by engagement with the flange 521 of the valve body 52 to constitute a valve body. The thick part 531 at the lower end of the packing 53 prevents the beer from flowing into the main pouring outlet 513 and the sub pouring outlet 514, and the flange 532 at the upper end of the packing 53 prevents beer leakage from between the cock body 51 and the lid 54. To do.
[0028]
The lid body 54 made of polypropylene has a valve body through hole 541 through which the valve body 52 penetrates at the center thereof, and a screw 543 formed on the inner peripheral surface of the side wall 542 is provided on the cock body 51. The cock body 51 is integrated with the screw 516 on the outer periphery of the upper end of the valve body storage portion.
[0029]
A coil spring 55 made of JIS SUS304 is positioned on the outer periphery of the valve main body 52 and biases the valve main body 52 and the packing 53 toward the main pouring outlet 513 and the sub pouring outlet 514.
[0030]
The lever 56 made of a synthetic resin such as polypropylene or nylon includes a handling portion 561 and a base 562. The base 562 is formed with an engagement protrusion 562a that engages with the engagement groove 522 of the valve body 52, and the lever 56 is engaged with the valve body 52 in the direction of the arrow with the engagement protrusion 562a as the center of rotation. Can tilt. Since the lever 56 is attached to the valve main body 52 by the engagement protrusion 562a and the engagement groove 522, the attachment is easier and the cost is higher than a method using a fastening means such as a bolt. Can be reduced.
The cock 5 having the above configuration is screwed and fixed to the cock mounting hole of the container body 1 via the O-ring 57 and the cock set screw 58.
[0031]
The state which pours beer from the cock 5 is shown in FIG. In FIG. 3, the beverage container to which the cock 5 is attached is omitted.
When beer is poured out, the lever 56 of the cock 5 is tilted as shown in the figure after the mug J is positioned below the main outlet 513 and the auxiliary outlet 514. Then, the valve main body 52 and the packing 53 in the cock 5 are raised and the sealed state is opened, and the beer in the container main body is poured out from the main pouring outlet 513 and the sub pouring outlet 514. The mug J is placed on the container body side because it is normally held at an angle as shown in FIG. 3 because large foaming occurs when the beer is poured directly to the bottom of the mug J and the original taste of the beer is impaired. The beer pouring flow A from the main pouring outlet 513 flows into the mug J along the side wall of the mug J.
[0032]
On the other hand, the beer pouring flow B from the sub-pouring outlet 514 directly reaches the beer stored in the mug J. In this way, when the beer pouring stream B reaches the beer stored directly in the mug J, fine bubbles can be formed in the beer. That is, when the beer pouring stream B reaches the beer in the mug J, the beer in the mug J is stimulated, and the carbon dioxide dissolved in the beer forms fine small bubbles by the stimulation. To do.
[0033]
The diameter of the main pouring outlet is desirably determined in the range of 4.0 to 9.0 mm in accordance with the size of the container, that is, the amount of brewed beer. If the caliber is too small, the dispensing speed will be slow, and you will feel frustrated when filling a full mug.If the caliber is too large, the dispensing time will be too fast and it will be difficult to control the dispensing. is there.
The diameter of the sub-outlet 514 is preferably determined from a range of 1.7 to 2.0 mm according to the size of the main outlet. This is because if the diameter is too small, the impact when reaching the beer in the mug J becomes small, the effect of foam generation becomes insufficient, and the sub-outlet 514 is easily clogged by the substance dissolved in the beer. Moreover, it is because the extraction speed | rate of the beer extraction flow B will become slow when the aperture is too large, and the impact which forms foam on the beer surface will become small.
[0034]
FIG. 7 is a perspective view showing the inside of the lower end of the cock 5. Since the spacers 513b and 513b are provided upstream of the main outlet 513, a space, that is, a storage portion 514a is formed upstream of the auxiliary outlet 514. When beer is about to flow into the main pouring outlet 513 and the sub pouring outlet 514, the reservoir 514a is filled with a predetermined amount of beer. That is, it is possible to secure a larger amount of beer flowing into the sub-outlet 514 and to apply pressure to the beer flow flowing out from the sub-outlet 514 to increase the flow rate of the beer flow.
[0035]
When the arrangement of the main outlet 513 and the auxiliary outlet 514 is reversed and the auxiliary outlet 514 and the main outlet 513 are arranged in this order from the side of the container body, the normal mug J is as shown in FIG. Since it is held at an angle, the pouring flow B from the sub-pouring outlet 514 collides with the side wall of the mug J and cannot reach the beer directly, and the fine foam generation function cannot be exhibited. Therefore, in the beverage container used in a fixed state as in the present embodiment, the arrangement of the main outlet 513 and the auxiliary outlet 514 is important.
[0036]
After the required amount of beer is poured into the mug J, the lever 56 is returned from the tilted state to the original state. When the lever 56 is tilted, the coil spring 55 disposed on the outer periphery of the valve body 52 urges the valve body 52 and the packing 53 downward in the drawing, that is, the lever 56 is urged in the returning direction. If the tilt state is simply released, the lever 56 returns to the original state.
[0037]
When the lever 56 returns to the original state, the valve main body 52 and the packing 53 are in the state shown in FIG. Immediately after beer pouring, a small amount of beer remains in the main pouring outlet 513, but since the slit 513 a is formed in the main pouring outlet 513, the remaining beer is immediately discharged from the main pouring outlet 513. Therefore, no dripping occurs as in the prior art.
[0038]
The beverage container in which the above elements are integrated is placed on a leg 6 composed of a support ring portion 61 and a leg portion 62. The support ring portion 61 of the leg 6 is not in contact with the outer container 2 in the radial direction (FIG. 5). Accordingly, when the beverage in the container body 1 is reduced and the entire container is lightened, when the lever 56 of the cock 5 is operated in the direction of the arrow, the beverage container is rotated counterclockwise around the support ring portion 61 on the cock 5 installation side. Try to rotate. Then, the leg arrangement surface 22 of the outer container 2 is lifted from the support ring part 61 on the side where the cock 5 is not installed, and the entire container becomes unstable. In order to prevent this from rising, the leg stop protrusion 25 is provided at the lower end of the outer container 2 with an appropriate width.
[0039]
In the above beverage containers, when refilling beer, a predetermined amount of beer is replenished after opening the lid 4 and the lid 4 is mounted again. In a state where the beverage container is left still, the liquid level of the beverage such as beer is located below the lid 4. On the other hand, beer is poured out by a cock attached to the lower part of the container body 1. Therefore, even if the lid 4 is not sufficiently mounted, there is no concern of beverage leakage from the lid.
[0040]
Moreover, since the heat insulation member 3 is interposed between the container main body 1 and the external container 2, the cold insulation property of the drink accommodated in the container main body 1 is further improved.
[0041]
【The invention's effect】
As described above, a pour tool main body having a beverage inlet, a beverage channel communicating with the beverage channel, a main outlet and a sub-outlet having a smaller opening diameter than the main channel, and the beverage channel. According to the beverage pouring device according to the present invention provided with the sealing means capable of sealing the beverage inflow path, fine bubbles can be formed when beer is poured from the beverage container. Further, if a slit is formed in the main pouring outlet, dripping can be prevented.
[0042]
In addition, as a beverage container to which the dispensing device of the present invention is attached, a container body having an opening in the upper part composed of a bottom wall and a side wall standing from the bottom wall, an external container for housing the container body, a container body, By using a heat insulating member disposed between the outer container and the lid body detachably attached to the opening of the container body, it is possible to prevent leakage of beverages such as beer and to improve cold insulation.
