Problems solved by technology
Therefore, spraying the fungicide onto the container while inserting the nozzle into the container may deform the thinned container due to the heat of the fungicide
[0005] In addition, in the sterilization method of supplying the sterilizing agent to the inner surface and the outer surface of the container without inserting the nozzle into the container as shown in Patent Document 2, it may be difficult to efficiently supply the sterilizing agent to the inner surface of the container.
In this case, in order to efficiently supply the sterilizing agent to the inner surface of the container, there is also a problem that the usage amount of the sterilizing agent must be increased.
[0006] In addition, as shown in Patent Document 3, there is also a method of using the heat imparted to the bottle by blow molding for sterilization, but since it is necessary to install a temperature adjustment device for adjusting the temperature of the bottle, it is costly, and because blow molding The final heat is one of the sterilization factors, so it is necessary to measure the temperature of the bottle after blow molding

Embodiment Construction
[0035] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 to Figure 8 It is a figure which shows one embodiment of this invention.
[0036] (content filling system)
[0037] First, according to figure 1 , the content filling system (aseptic filling system, antiseptic filling system) of the embodiment will be described.
[0038] figure 1 The illustrated content filling system 10 is a system for filling a bottle (container) 100 with content such as a beverage. The bottle 100 can be produced by biaxial stretch blow molding of a preform produced by injection molding a synthetic resin material. As the material of the bottle 100, it is preferable to use a thermoplastic resin, especially PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), or PEN (polyethylene naphthalate). ester). In addition, as a container, glass, a can, paper, a bag, or these composite containers may be sufficient. In this embod...

Abstract
A container sterilization device (11) is provided with: a conveyance mechanism (40) that conveys a container (100); and a supply unit (50) that supplies a sterilizer to the container (100) that is being conveyed by the conveyance mechanism (40). The supply unit (50) has a nozzle (51) for spraying the sterilizer. The nozzle (51) does not move in a vertical direction and moves in synchronization with the container (100) that is being conveyed by the conveyance mechanism (40) without being inserted into the container (100).
Description
technical field [0001] The present disclosure relates to a container sterilization device, a content filling system, a container sterilization method, and a content filling method. Background technique [0002] There is known an aseptic filling system (antiseptic filling system) that fills a sterilized container (PET bottle) with sterilized contents in an aseptic environment, and then closes the container with a cap. Specifically, in the aseptic filling system, the molded container is supplied to the aseptic filling system, and in the aseptic filling system, a hydrogen peroxide solution as a sterilizing agent is sprayed on the container. Thereafter, it is dried to sterilize the container, and then the contents are aseptically filled into the container. [0003] As a sterilization method for sterilizing a container, there are known methods of spraying a sterilizing agent while inserting a nozzle into the container from the mouth of the container, and supplying a sterilizing ...
