Embodiment approach 1

[0147] like figure 1 As shown, the package 1 has a bottle 2 as a container and a cap 3 as a cap. The external thread 2b is formed at the mouth 2a of the bottle 2, and the internal thread 3a is formed at the cap body 3, and the sealing of the mouth 2a of the bottle 2 is realized by screwing the internal and external threads 3a and 2b.

[0148] The bottle 2 is formed by blow molding a substantially test tube-shaped PET preform (not shown). The bottle 2 is not limited to being made of PET, and other resins such as polypropylene and polyethylene may also be used. The preform is formed by injection molding or the like, and has a substantially test tube-shaped body and the same mouth portion 2 a as the bottle 2 . The external thread 2b is formed at the mouth portion 2a simultaneously with molding the preform. The cover body 3 is formed by injection molding with resin such as polypropylene, and similarly, the internal thread 3 a is also formed when the cover body 3 is formed.

Embodiment approach 2

[0199] like Image 6As shown, unlike the case of Embodiment 1, in this Embodiment 2, wheels 11b, 11c, 11d are provided between the introduction conveyor belt 11a and the wheel 12, and these wheels 11b, 11c, 11d are accommodated in the first aseptic cavity 23. Bottle 2 arrives at wheel 11c by introducing conveyor belt 11a through wheel 11b, blows hydrogen peroxide gas b from nozzle 75 while advancing around wheel 11c, reaches wheel 12 through wheel 11d, uses heat while advancing around wheel 12 The water is sterilized.

[0200] like Figure 7 As shown, the wheel 11c is installed horizontally on the rotating shaft 61 standing on the table 60, and can rotate about the rotating shaft 61 as an axis. The support 61a extends upward from the disk surface of the wheel 11c, and a manifold 62 is fixed to the upper end of the support 61a, and the above-mentioned hydrogen peroxide gas b flows into the manifold 62 . The conduit 63 extends upward from the center of the upper part of the ...

Embodiment approach 3

[0212] like Figure 8 As shown, the container of the package 28 in Embodiment 3 is formed as a pressure-resistant bottle 2 whose bottom 2c is a petal-shaped or champagne-bottomed shape. The bottle 2 is filled with a beverage a that is pressurized in the bottle 2 in the form of gas, such as a milk-based carbonated beverage, a carbonated beverage containing fruit juice, or a fruit-colored carbonated beverage.

[0213] like figure 2 As shown, the beverage a is pressed into carbon dioxide gas (step 4) after heat sterilization (step 2) and cooling (step 3). Then, it is filled into a petal-shaped or champagne-bottomed bottle 2 at a low temperature (step 5), and the packaging body 28 is produced through the same process as in Embodiment 1.

[0214] In addition, in this third embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and repeated explanations are omitted.

Abstract

A method of aseptically filling an acidic drink and storing the same at an ordinary temperature at a low cost without using a highly heat-tolerant container or an expensive production system whereby an acidic drink, which has a certain level of acidity and contains an approved amount of spores remaining therein, can be appropriately stored while avoiding putrefaction. The inside of a container (2) is pasteurized with a bactericide (b) and hot water (c) so as to prevent the survival of bacterial vegetative cells, molds and yeasts while allowing the survival of bacterial spores. Next, a pasteurized content (a), which has such an acidity level as being capable of preventing the bacterial spores as described above from germination, is filled in this container at an ordinary or low temperaturefollowed by sealing the container with a cap (3) to give a packed product (1).

Description

technical field [0001] The present invention relates to a package in which contents such as beverages are filled in a container such as a bottle in a commercially aseptic form, a manufacturing method and a manufacturing device thereof. Background technique [0002] (1) According to the Food Sanitation Law, it is not necessary to sterilize acidic beverages (pH<4) to which a specified carbon dioxide gas pressure is added, but for those containing plant or animal components, they must be sterilized regardless of the presence or absence of carbon dioxide gas pressure. Sterilization, therefore, must be carried out at 65°C for 10 minutes for carbonated beverages containing vegetable or animal components and having a pH of less than 4.0 (e.g., milk carbonated beverages, fruit juice carbonated beverages, fruit colored carbonated beverages) heating. [0003] The sterilization is carried out in the following manner. For example, the acidic drink is filled in a heat-resistant and p...
