2. Description of the Related Art Conventionally, when manufacturing products filled with carbonated drinking water, juice, etc., first, after filling carbonated drinking water, juice, etc. in a bottle, foaming at the time of filling and liquid on a conveyor. The bottle mouth, which was contaminated with the internal solution overflowing due to spillage or the like, was washed. This bottle mouth cleaning is performed by, for example, Jitsuko Sho 53-222.
A method of closing the opening of the bottle mouth with a seal plate or the like and covering it with water from the surroundings has been adopted as described in Japanese Patent No. 13 publication.

After cleaning the bottle mouth in this way, the bottle mouth is covered with a cap 1 as shown in FIG. The cap 1 is a metal cap that can obtain high airtightness by using packing together, and includes a cap body 2 formed into a substantially bottomed cylindrical body and a plurality of bridges 3 at the lower end of the cap body 2. Pill fur proof ring (hereinafter abbreviated as PP ring) 4 integrally formed with ... And soft polyvinyl chloride resin and ethylene vinyl acetate fitted in the top plate portion 5 of the cap body 2. It is composed of a thin disk-shaped packing 6 made of a soft material such as a copolymer resin or a polyethylene resin.

The cap 1 has no thread formed on the outer peripheral portion of the cap body 2, and is attached to the bottle mouth as follows. First, the cap 1 is covered with the cap chute on the mouth of the bottle moving on the carrier. Then, as shown in FIG. 4, the cap 1 is pressed against the bottle mouth 9 by the pressure block 8 of the capping machine 7, and the peripheral portion 5a of the top plate 5 of the cap 1 is pressed by the pressure block 8 to reduce the diameter. The roll-on roller 10 forms an internal thread 13 corresponding to the external thread 12 on the outer periphery of the bottle mouth 9 on the peripheral wall portion 11 of the cap 1, and the pill fur proof roller 14 further connects the PP ring 4 at the lower end of the cap 1 to the bottle mouth 9 side. Get involved in. As a result, the cap 1 is securely attached to the bottle mouth 9 as shown in FIG.

By the way, the above-mentioned conventional cap has the following problems, and it is desired to solve them. As described above, when the cap 1 is attached to the bottle mouth 9 by the capping machine 7, for example, the bottle accidentally rocks and the contents of the bottle overflow from the bottle mouth 9 to the outer peripheral surface of the bottle mouth 9. And may adhere to the inner peripheral surface of the cap 1. For this reason, when the cap 1 is attached to the bottle mouth 9, although there are some differences, the contents adhere to the inner peripheral surface of the cap 1 and the outer peripheral surface of the bottle mouth 9. Therefore, when the content contains a large amount of sugar such as carbonated beverages and fruit juice, the overflowed content is dried between the cap 1 and the bottle mouth 9 after mounting the cap, and the residual sugar is adhesive. Even if an attempt is made to rotate the cap 1 for the purpose of unsealing, it may be difficult to rotate the cap 1 and the unsealing may be difficult.

The present invention has been made in view of the above circumstances, and when the contents containing a large amount of sugar overflow when the cap is attached and adhere to the vicinity of the bottle mouth, the contents may interfere with the opening operation. It is an object of the present invention to provide a bottle mouth cleaning method capable of washing away contents that have adhered so that they do not exist.

[0007]

According to the bottle mouth cleaning method of the present invention, a cap having a small hole in the peripheral wall is attached to the bottle mouth,
Next, the method is characterized in that a fluid having a cleaning function is poured from the small hole of the cap. Examples of the fluid having a cleaning function include water, hot water, steam and the like.

[0008]

When the cleaning fluid such as water, hot water or steam is blown into the small hole of the cap, the cleaning fluid flows between the inner peripheral surface of the cap and the outer peripheral surface of the bottle mouth. This allows the contents adhering between the cap and the bottle mouth to be washed away.

[0009]

FIG. 2 shows an example of a cap with a small hole for cleaning a bottle mouth used in the cleaning method of the present invention. The cap 15 has a small hole 1 for cleaning the bottle mouth at an upper portion of the peripheral wall portion 16.
7 is formed to have the same shape and size as the conventional cap 1 (FIG. 3). That is, in the cap 15, the bridge 18, the PP ring 19, the top plate portion 20, the packing 21, the peripheral wall portion 22 and the like are
The bridge 3, the PP ring 4, the top plate portion 5, the packing 6, the peripheral wall portion 11 and the like in the cap 1 are formed in the same shape and the same size.

The small holes 17, ... As shown in FIG. 1, the upper end of the female screw 23 formed on the peripheral wall portion 22 corresponding to the male screw 12 of the bottle mouth 9 when the cap 15 is attached to the bottle mouth 9. 23a and a packing 21 fitted inside the top plate portion 20 are provided at equal intervals along the circumference of the peripheral wall. Further, as shown in the figure, these small holes 17 are formed by cutting lines along the circumference of the peripheral wall portion 22 along the circumference of the peripheral wall portion 22 and bulging the upper part of the cutting lines inward. The opening surface of the small hole 17 is substantially parallel to the top plate portion 20.

After the cap is attached to the bottle mouth as shown in FIG. 1, in this bottle mouth cleaning method, the cap 1
Water, hot water, steam or the like is sprayed from above diagonally above 5 to the small holes 17. Then, these water, etc., will smoothly
It flows between the outer peripheral surface and the inner peripheral surface of the cap 15. Water or the like injected from the small holes 17 between the inner peripheral surface of the cap 15 and the outer peripheral surface of the bottle mouth 9 flows down along the male screw 12 of the bottle mouth 9, while the inner peripheral surface of the cap 15 and the outer peripheral surface of the bottle mouth 9 are flown. The sugar adhering to the surface is washed away, and the score 24 forming the bridge 18 or the PP ring 19 from the lower end to the cap 15
It leaks out. As a result, the inner peripheral surface of the cap 15 and the bottle mouth 9
Since sugar does not adhere to the outer peripheral surface, there is nothing that hinders the opening of the cap 15, and the opening operation can be easily performed.
