Description

[Detailed description of the invention] [Industrial application field] This invention is a cup-type beverage vending machine that dispenses a drink prepared by an in-machine mixing device into a cup delivered onto a bend stage. This invention relates to a beverage nozzle for injecting beverage into a cup.

[Conventional technology]

This is the fourth cup-type beverage vending machine of this type.
The one shown in the figure is known. In the figure, a beverage vending machine 1 sends predetermined amounts of hot water from a hot water tank 2 and powdery raw material from a raw material container 3 to a mixing device 4 in response to a sales signal, where the raw materials are mixed and dissolved in hot water to produce a beverage. Prepare. On the other hand, the cup 7 is carried out from the cup storage cylinder 5 via the cup chute 6 to the bending stage 8. Then, the beverage is guided through the beverage pipe 9 to a beverage nozzle 10 at the tip of the pipe, and is injected into the cup 7 on the bending stage 8 from this beverage nozzle. Thus, the customer can hold the cup 7 in his hand and take it out from the bend stage 8 to drink the beverage.

The beverage nozzle 10 has a substantially cylindrical shape and has an oval opening at its tip that is cut diagonally with respect to the nozzle axis, and is bent diagonally downward so that the opening surface 11 is approximately vertical. It is fixedly held on the side wall of the stage 8.

Furthermore, the beverage nozzle 10 is placed in the relative position shown in FIG. 5 so as not to interfere with the removal of the cup 7 and so as not to interfere with the cup chute 6. That is, the tip of the beverage nozzle 10 is located slightly inside the upper edge of the cup 7.

[Problem that the invention attempts to solve]

By the way, in the conventional beverage vending machine, when the beverage is poured into the cup 7, the beverage A that is vigorously discharged from the beverage nozzle 10 is accommodated in the cup 7 without any problem, as shown in FIG. For example, beverage B, which has weakened and has just finished dispensing, begins to flow down the nozzle in the form of streaks, gradually loses its discharge force and changes its discharge direction downward, and eventually becomes drop-like and flows down the nozzle. It is pulled backward by the adhesive force of the tip of 10 and drips onto the upper end surface of the cup 7,
It falls on the outside of the cup 7, bounces off the bend stage 8, and adheres to the outside surface of the cup 7. This has the disadvantage of staining customers' hands with beverages and making them feel uncomfortable.

This invention enables cup-type beverage vending machines to ensure that even when the force of the beverage discharged from the beverage nozzle has weakened, such as at the end of dispensing or at the beginning of dispensing, the beverage is reliably contained within the cup, and there is no need to worry about causing discomfort to customers. The purpose is to provide a nozzle.

[Means for solving problems]

In order to achieve the above object, this invention provides a beverage nozzle for a cup beverage vending machine which is held obliquely downward above the cup on a bend stage and has a substantially elliptical opening surface.
The opening surface is held substantially horizontally, with the tip of the opening surface being lower than the rear end, and a lid is further provided to cover the rear of the opening surface, and the tip is positioned above the inner side of the periphery of the cup on the bending stage. shall be allowed to do so.

[Effect]

Immediately before the end of the beverage dispensing, the ejection force is almost gone and the beverage liquid becomes droplets, which travels along the periphery of the nozzle end from the rear end of the opening surface of the beverage nozzle and drips into the cup from the nozzle tip. Also, regarding the beverage liquid that still has some momentum and flows down inside the nozzle in streaks,
When it reaches the rear end of the nozzle's opening surface, it is blocked by the lid surface at the end of the nozzle, weakening the ejection force, and due to the surface tension of the corner formed by the nozzle end and the lid, it is smoothly guided toward the periphery of the nozzle, and the nozzle exits. Drip into the cup from the tip.

〔Example〕

1 to 3 show an embodiment of this invention, and parts common or identical to those in FIGS. 4 to 6 are designated by the same reference numerals.

In FIGS. 1 to 3, the beverage nozzle 10 held obliquely downward above the bending stage 8 is formed so that the opening surface 11 is approximately horizontal, but the tip 12 is lower than the rear end 13. be done. 14 is a lid that closes the rear part of the oval opening surface 11. This beverage nozzle 10 is arranged so that its tip 12 is inside the upper edge of the cup 7 delivered to the bending stage 8.

In the above-mentioned configuration, when selling drinks, the drink A that is vigorously discharged from the drink nozzle 10 is accommodated in the cup 7 without any problem as in the conventional case. For example, at the end of dispensing, the beverage B, which loses its ejection force and is about to turn into drops, flows gently through the bottom of the cylindrical body of the beverage nozzle 10 and reaches the rear end 13, from where it flows into the opening surface 11.
The water flows along the periphery of the cup 7, travels along the periphery of the opening surface 11, gathers at the tip 12, forms a droplet, and drips into the cup 7. In addition, for beverages that have some discharge force and flow down the nozzle in streaks, when they reach the rear end 13 of the nozzle, they are blocked by the inner surface of the lid 14 and the discharge force is weakened, and the nozzle end and the lid are Due to the surface tension of the corner formed by the liquid, the liquid is smoothly guided toward the periphery of the nozzle, and then, like the droplet-shaped beverage described above, it travels along the periphery of the opening surface 11 and drips from the nozzle tip into the cup 7. Therefore, even the beverage B which drops with a weak ejection force is reliably accommodated in the cup 7, and the beverage does not adhere to the outer surface of the cup 7.

[Effect of idea]

According to this invention, the opening surface is held approximately horizontally and the tip of the opening surface is held lower than the rear end, a lid is provided to close the rear portion of the opening surface, and the tip is bent around the periphery of the cup on the bend stage. By locating the nozzle on the inside and upper side, the beverage that is poured into the cup through the beverage nozzle is reliably contained within the cup, even if the beverage loses its force and falls in the form of drops. Therefore, the customer's hands are not soiled with the beverage adhering to the outer surface of the cup, and the discomfort caused to the customer is eliminated.
