Problems solved by technology

If such a fungicide is attached to the preform and enters the molding machine and is vaporized, these chelating agents may adhere to and accumulate in the molding machine, contaminate the molding machine, and be mixed into containers such as bottles as foreign matter.
[0017] Moreover, when the sterilant is to be discharged from the preform by using the flame of the burner after the sterilant is attached to the preform, it may lead to complicated and expensive steps and devices.
[0018] In addition, according to the method of sterilizing the inside of the preform with water vapor without using a fungicide, it is necessary to maintain the preform at a predetermined temperature for a predetermined time until the sterilization is effective, so there is a problem that a water removal step is required after sterilization
[0019] Furthermore, in the prior art, after sterilization by attaching a bactericide to the preform, bacteria may be mixed into the bottle when it is blow-molded with high-pressure air or when the bottle is transported to the filling area.
While it is not impossible to sterilize the high-pressure air circuit, extension rods, molds, bottle delivery area, etc. within the blow molding machine to main

no. 1 approach

[0067] According to the online production system of the first embodiment, it is possible to manufacture figure 1 package shown.

[0068] Such as figure 1 As shown, the package has a bottle 2 as a container and a bottle cap 3 as a cap.

[0069] In this embodiment, the bottle 2 is manufactured using PET, but it is not limited to PET, and the bottle 2 may be manufactured using other resins such as polypropylene and polyethylene. The mouth 2a of the bottle 2 is formed with an external thread 2b.

[0070] The bottle cap 3 is formed by injection molding of resin such as polypropylene, and the internal thread 3a is formed simultaneously with the molding of the bottle cap 3 .

[0071] The bottle 2 is filled with the sterilized beverage a in a state where the inside of the bottle 2 has been sterilized in advance. After the beverage a is filled, the mouth 2a of the bottle 2 is covered with the bottle cap 3, and the mouth 2a of the bottle 2 is sealed by screwing the internal and exte...

no. 2 approach

[0149] Such as Figure 6 As shown in (E), in the second embodiment, as figure 2 The bottle 2 taken out from the mold 4 as shown in (D) is rinsed with sterile hot water H to perform main sterilization. exist Figure 6 In (E), reference numeral 46 denotes a nozzle for hot water rinsing that sprays sterile hot water H. As shown in FIG. The temperature of the hot water H is maintained within a range such that the bottle 2 does not deform.

[0150] Bottle 2 is the same as the first embodiment, in figure 2 The stage of the preform 1 shown in (B) is sprayed with water vapor, and then heated in a moist heat state to pre-sterilize almost all microorganisms except bacterial spores. Therefore, by this hot water rinsing, bacteria surviving in the molding stage of the above-mentioned bottle 2 are sterilized.

[0151] Such as Figure 6 Shown in (F), beverage a is filled in bottle 2 after being rinsed by hot water, and as Figure 6 Cap 3 on the bottle as shown in (G).

[0152] The ...

no. 3 approach

[0158] According to the online production system of the third embodiment, it is also possible to manufacture figure 1 package shown.

[0159] The above-mentioned bottle 2 forms a container in the same procedure as described in the first embodiment, and forms a package through beverage filling and sealing. However, in the first embodiment, as figure 2 As shown in (A), water vapor W is sprayed from the nozzle 24 to the preform 1. In contrast, in the third embodiment, as Figure 8 As shown in (A), hydrogen peroxide mist or gas L is sprayed from the nozzle 24 to the preform 1 .

[0160] From the hydrogen peroxide mist or gas L sprayed from this nozzle 24, utilize and Figure 4 Shown mist generator 7 is generated by the mist generator of the same structure.

[0161] By spraying hydrogen peroxide mist or gas L, the surface of the preform 1 is attached and formed at 0.0035 μL / cm 2 ~0.35μL / cm 2 Coagulation film of hydrogen peroxide in conversion of 35% by weight in the range. I...

Abstract

A preform (1) is sprayed with a water vapor (W) and heated while being made to travel continuously, thus performing preliminary sterilization; this preform which has been preliminarily sterilized is blow-molded within a forming die (4), which likewise continuously travels, and a bottle is formed; the bottle is extracted from this continuously traveling forming die, and while heat remains the bottle is sprayed with a condensed mist (M) or gas (G) of hydrogen peroxide and is air-rinsed; and this bottle is filled with a beverage and sealed with a cap while likewise being made to travel continuously. The bottle sterilization process in an inline system can be simplified.

Description

technical field [0001] The invention relates to a beverage filling method and device. Background technique [0002] In the past, as the aseptic filling method of the online production system, for example, the following methods have been proposed in patent documents 1, 2, 3, 5, 6, 7, and 8: ) and other preforms are sterilized at the same time, and the preforms are formed into bottles using a blow molding machine, and beverages are filled into the bottles, and then capping operations are performed to make aseptic packages. These methods are methods in which sterilization treatment is performed at a preform stage before bottle formation instead of sterilization treatment after bottle formation. [0003] Patent Documents 1, 5, 6, 7, and 9 propose the following method: injecting hydrogen peroxide or other bactericide gas to the preform before blow molding to sterilize the preform, then heating the preform to an appropriate temperature for stretching, and then Perform stretch bl...
