DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel synthetic resin cup which can be supplied to a beverage vending machine and used sufficiently.

[0002]

2. Description of the Related Art As a cup container which can be supplied to a beverage vending machine and used, a conventional paper cup is mainly used and a cup made of a synthetic resin has not been used. Since the synthetic resin cup can be a transparent product like a glass cup, it is preferable to feel like using a glass cup when filling and drinking a beverage. However, this synthetic resin cup is expensive and has been unsuitable for disposable beverage vending machines and the like.

Recently, however, sheet molding technology has been developed for synthetic resin cups, and sheet moldings using thin synthetic resin sheets with relatively few materials can be made, and can be supplied to disposable beverage vending machines. Inexpensive synthetic resin cups have been developed.

[0004]

A very common synthetic resin cup has a structure as shown in FIGS. 6 and 7. FIG. This configuration is similar to that shown in FIG.
1 has a cup body 23 formed downward from the bump-shaped portion 22 peculiar to sheet molding formed to the lower end with a taper angle of about 5 degrees, and a stack pitch d of about 7 mm is formed at the lower end of the cup body. A bottom 24 having a step 25 to make up is provided. The table expressed in this specification
The par angle refers to the inclination angle of the taper.

[0005] When a cup is supplied to a beverage vending machine, the cup is usually supplied in a state where 50 cups are stacked, but when the 50 cups are stacked, the cup is supplied in a substantially straight state without bending. Is required.
In the case of the general synthetic resin cup shown in FIGS. 6 and 7, when the cups are stacked, the bump-shaped portion 22 formed inside the upper edge flange 21 as shown in FIG. Is firmly stacked by contacting the outside of the cup body 23, even if 50 cups are stacked, the stacking state is firm and there is no risk of bending. However, since the bump-shaped portion 22 comes into contact with the upper cup body 23, there is a problem that meshing occurs at this portion and a blocking phenomenon occurs.

The inventors of the present invention have developed an improved synthetic resin cup shown in FIGS. 4 and 5 in order to solve the problems of the above general synthetic resin cup, and have repeated various experiments. The improved synthetic resin cup has an inclined upper region 36 having a taper angle of approximately 14 degrees in the uppermost region including the bump-shaped portion formed inside the upper edge flange 31. Part 3
Step 3 having a cup body 33 formed downward from 6 to a lower end thereof with a taper angle of about 5 degrees, and forming a stack pitch d of about 7 mm at the lower end of the cup body.
A bottom 34 with 5 is provided. Then, the width of the inclined upper region 36 is set to be equal to the stack pitch d so that the inclined upper region 36 of the upper cup does not abut on the bump 32 of the lower cup when the cups are stacked for stacking. It was configured to be narrower than the width.

In the improved synthetic resin cup having the above-described structure, an inclined upper region 36 is provided so that the upper cup body 33 and the bump-shaped portion 32 of the lower cup do not come into contact with each other. Although there is no danger of blocking when many cups are stacked, the gap between the main body 33 following the upper region of each cup and the bump-shaped portion 32 of the lower cup is formed in a state where many cups are stacked. This causes a new problem of bending in the stacking state. The bending in the stacking state causes a problem that automatic supply of, for example, 50 cups cannot be smoothly performed.

Further, the improved synthetic resin cup includes:
There is also a problem that a certain type of vending machine cup disconnection mechanism does not operate smoothly. That is, FIG. 3 shows a schematic explanatory view of a cup separating mechanism of this kind of vending machine. In this separating mechanism, the cup dropper 41 always supports 4 to 8 cups, and the cup dropper 41 When the lowermost cup is cut off and supplied and the number of cups supported by the cup dropper becomes four, this is sensed and four cups are dropped and supplied from the stacked cups in the column 42. is there.

To this end, an openable / closable column bottom plate 43 is provided at the bottom of the column. The column bottom plate is closed to support a large number of stacked cups. The wedges 44 that lock the cups of the tier are closed, the stacked cups above the wedges are supported by the wedges, and the column bottom plate 43 is opened to drop and supply four cups. Therefore, in the above-mentioned improved synthetic resin cup, the inclined upper region 3
Since the wedge 44 holds the cup 6, the upper cup 36 is inclined by the inclination of the inclined upper region 36, so that the entire cup is inclined as shown in FIG. 3, and the lower cup hits the inner wall of the column 42 and cannot be dropped. occured.

The present invention has been made in consideration of the above-described problems, and in addition to preventing bending in a state in which a large number of cups are stacked, smooth automatic supply can be performed without blocking. It is an object of the present invention to provide a new synthetic resin cup suitable for a machine.

[0011]

In order to achieve the above object, in the synthetic resin cup of the present invention, a slightly nearly vertical shape is provided in the uppermost region including the bump-shaped portion formed inside the upper edge flange. It has an uppermost region having a taper angle, has a step portion having a relatively large taper angle continuously to the uppermost region, and is formed to a lower end with a slight taper angle continuously to this step portion. The cup body has a bottom with a step at the lower end of the cup body, the step forming the stack pitch. Yes position the stepped portion so as to be opposed close to or abut on, the
Adjust the taper angle of the uppermost region and the main body to about 5 degrees.
Further, the taper angle of the step portion is approximately 30 degrees.
Characterized in that that is the other.

[0012]

In the synthetic resin cup of the present invention configured as described above, in a state in which a large number of cups are stacked, the step portions of the upper cups respectively face the proximity or contact with the bump-shaped portions of the lower cups. No gap is formed between the upper cup and the lower cup. Therefore, there is no possibility of bending in a state where many cups are stacked. Next, since the bump-shaped portion of the lower cup is opposed to, adjacent to or abuts on the step having a relatively large taper angle of the upper cup,
Even if they abut, they do not engage at this portion. Therefore, there is no risk of blocking in the stacking state.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. In the drawing, reference numeral 1 denotes an upper edge flange formed on the upper edge of a synthetic resin cup. When this cup is formed by a synthetic resin sheet, a bump upper portion 2 is formed inside the upper edge flange. In the figure, reference numeral 6 denotes an uppermost portion of the cup including the bump-shaped portion, which is formed with a slight taper angle which is almost vertical, and in this embodiment, this taper angle is set to approximately 5 degrees.

In the figure, reference numeral 7 denotes a step portion formed continuously with the uppermost region 6 and has a relatively large taper angle. In the embodiment, it has a taper angle of about 30 degrees. The taper angle of the step is not limited to about 30 degrees, but may be any angle from about 15 degrees to near 90 degrees. Also, this step is tapered
-The cross section of the inclined surface at the angle may not necessarily be linear,
It may be a curved surface. This step serves to prevent stacking deflection and blocking, as will be described later. In the figure, reference numeral 3 denotes a cup body,
And has a slight taper angle. In this embodiment, the taper angle is set to about 5 degrees. The lower end of the cup body 3 has a bottom 4,
The bottom 4 has a step 5 forming a stack pitch d.

Further, in the synthetic resin cup of the present invention, even if the cup is supplied to a beverage vending machine having a cup separating mechanism shown in FIG.
Uppermost region 6 having a slight taper angle close to a substantially vertical shape
Therefore, the cup does not tilt greatly and the cup does not tilt so much that the automatic dropping of the cup is not hindered.

[0017]

As described above, in the synthetic resin cup of the present invention, there is no risk of bending in the stacking state, and there is no risk of blocking since the respective cups do not engage in the stacking state. Accordingly, there is no problem in supplying the beverage to the beverage vending machine, and even in the automatic supply of the cup, smooth supply can be performed without any problem.
