<Industrial Application Field> The present invention provides a first
Triangular fold area shown with diagonal lines as shown
C 1 is a rectangular parallelepiped carton A having a bottom part a 1 or a head part b 1 , and as shown in FIG. This invention relates to a sterilization device for cylindrical packaging materials that form a folded part, such as a gusset type bag B having a width of 2 . <Prior art> Conventionally, in a package having folded parts, the packaging material is sterilized in-line, the contents are filled and sealed while taking measures to prevent secondary contamination, and the package is then formed. At present, sufficient sterilization is not carried out except when necessary. On the other hand, when forming a packaging container before sealing, there are two methods for sterilizing the folded portion: sterilizing, forming, filling and sealing the rolled up packaging material in-line, and forming the packaging container offline. rear,
Or, after forming a part, sterilize, fill the contents,
If it is sealed, it is done. In the former case, the packaging material is sent in a roll and undergoes sterilization, but from this point onwards, measures to prevent secondary microbial contamination (such as turning the entire machine into a clean booth) are taken until the sealing process. In addition, if the packaging material is divided into individual packaging containers before filling, there should be no foreign matter mixed in when cutting the packaging material, and if paper is used in laminated materials, paper The microorganisms present inside the container will escape to the outside and contaminate the packaging material. In addition, when sterilizing the latter shaped packaging container, for example, Japanese Patent Application Laid-Open No. 58-203823 (Fig. 5)
As shown in Figure 1, there is a sterilization method in which the bottom is formed by folding the bottom part using a forming mandrel, and then a sterilizing chemical solution is sprayed during the extraction process. However, it is difficult to sterilize microorganisms present in the folded area. <Problems to be Solved by the Invention> In view of the above, the present invention provides an apparatus that can completely prevent secondary contamination and perform sufficient sterilization. At the time of molding the bottom or head of a cylindrical packaging material for forming a packaging container, the folded part is sterilized and molded to create a completely sterilized and hygienic folded part. The purpose of this invention is to provide a sterilization device capable of sterilization. <Means for Solving the Problems> The present invention provides a sterilizer for sterilizing a cylindrical packaging material having folded portions in a sterile chamber, in which an unformed cylindrical packaging material is inserted into a mandrel that moves the cylindrical packaging material. A sterilizer spray nozzle that applies a sterilizing solution to the edge of the material, a hot air nozzle that improves the sterilization effect with heated air and melts the sealant at the same time as removing the chemical, a crimping bar that crimps the end, a cooling bar that cools the crimped part, and a folding This sterilization device for cylindrical packaging materials is characterized in that molding plugs for molding the overlapped portions to be flat are sequentially provided along the moving direction of the mandrel. <Function> With the sleeve cut to a certain length inserted into the mandrel, the end of the cylindrical packaging material is sterilized, and then the folded part is formed. Cut surfaces can also be completely sterilized. Furthermore, since the sterilizing liquid is applied to the cylindrical state, the mandrel into which the cylindrical packaging material is inserted can also be sterilized at the same time. <Example> Next, an example of the present invention will be described using the drawings. As shown in FIG. 3, in a sterile chamber 12 provided with a cylindrical packaging material introduction port 13 and a transfer port 14, there is provided a forming and transporting mechanism in which mandrels 1 are provided at regular intervals on a chain 3 that moves intermittently. Then, the cylindrical wrapping material 2 is inserted into the mandrel in the order in which the mandrel 1 is moved, and fixed, leaving only the part to be molded. Next, a spray nozzle 4 is used to spray the disinfectant onto the end of the cylindrical packaging material 2 that has been attached, a hot air nozzle 8 is used to heat the end of the cylindrical packaging material 2, and the inner surfaces of the heated cylindrical packaging material 2 are heated. It is equipped with a crimping bar 9 for crimping, a cooling bar 10 for cooling the crimped part, and a molding plug 11 for flattening the folded part. This is a sterilizer for cylindrical packaging materials that transfers the materials to the next process. Here, the mandrels may be moved by a mechanism in which a plurality of mandrels are attached to a rotating shaft and rotated, instead of being moved by a chain. Next, a specific example of sterilization using the sterilizer shown in FIG. 3 will be explained. Here, the structure of the cylindrical packaging material is, for example, as shown in Figure 4, polyethylene (20μ) (25)/paper (200g/
m 2 ) (26) / Polyethylene (20μ) (27) / Aluminum (9μ) (28) / Polyethylene (60μ)
(29) A laminated material with a five-layer structure (inner surface), used in a rolled form. Hereinafter, sterilization of a cylindrical packaging material will be explained step by step. The packaging material that has come out of the roll-up is side-sealed to form a cylindrical shape. Next, holes are made for the date-printed straws, lines are added, and each straw is cut according to the eye marks.
Then, the completed cylindrical packaging material 2 (size
66φ145mm) from the opposite direction of the head to be formed into the mandrel 1 in the mounting process (a), and insert the 40mm
Fix it in the protruding position. In the next sterilization step (b),
5 concentrations of hydrogen peroxide at room temperature are added as a disinfectant to the opening of the cylindrical packaging material 2 inserted into the mandrel 1.
A sterilizing agent consisting of a 15% aqueous solution is applied as a mist from a spray nozzle 4 with pressurized sterile air 6. The amount of coating is 80g/ m2 , which is larger at the tip.
In the mandrel drive part, it was 4.5 g/m 2 .
Immediately after applying the hydrogen peroxide aqueous solution, in the next heating step (C), the hydrogen peroxide aqueous solution is heated by spraying sterile 270°C hot air from the hot air nozzle 8 through a heater with pressurized sterile air 16, The sterilization effect has been improved and the folded area has been completely sterilized. Next, the polyethylene of the sealant at the end of the cylindrical packaging material 2 is melted, and before the temperature drops, it is crimped in the crimping process (d) using a crimping bar 9 and a cooling bar 10 with a seal width of 6 mm, and then cooled. Cooling was performed in step (e). Then, in moving to the next forming process (f), the seal part is flattened using the forming plug 11, the folded part is pushed outward, and that part is folded in one step of the edge folding process (g). A cylindrical packaging material whose folded portion was completely sterilized by being brought into close contact with the main body was obtained. The sterilizing effect of the above sterilizer will be explained. First, we will show the results of testing for lethal effects. A spore suspension of Batillus coagulans was uniformly applied to the polyethylene surface of the inner sealant of the material used, and the number of bacteria was adjusted to 10 5 spore/cm 2 , followed by sterilization. As the disinfectant, a 15% aqueous hydrogen peroxide solution at room temperature was applied using an airbrush, and the amount applied was 0.3 g per cylindrical packaging material. Next, sterile hot air was blown at the temperature of the outlet at 270°C. The disinfectant applied after about 1 second
At the same time as the evaporation, the polyethylene sealant was melted, and the edges of the packaging material were crimped and cooled to achieve a complete seal. The prepared container was collected aseptically and the number of viable bacteria on the bottom and folded portion was tested by wiping. The results are shown in Table 1. At the same time, after forming the folded part, an aqueous hydrogen peroxide solution (concentration 30% by weight) was sprayed, and sterilization was performed using aseptic hot air at a temperature of 270°C (Comparative Example 1). Also, the results of a test for the number of viable bacteria after sterilization using 0.1% by weight hydrogen peroxide and ultraviolet rays (Comparative Example 2) are also listed.

有する。[Table] Furthermore, after sterilization as described above, the products of the present invention are filled and packaged with corn cream soup of PH 7.0 after main sterilization of the torso, and the product does not spoil and can be stored for a long time at room temperature (6. However, in other Comparative Examples 1 and 2, which were sterilized and filled and packaged with the same corn cream soup, the main sterilization of the body was performed before filling and packaging. However, rot due to surviving bacteria in the folded portion occurred within a week. <Effects> The present invention has the above configuration, and if sterilization is performed using the device of the present invention, not only the folded portion can be completely sterilized, but also the molding mandrel can be sterilized at the same time. This is possible, and there is no accumulation of microbial contamination due to sequentially sent packaging materials, and it is hygienic without contaminating the packaging. Therefore, the present invention is very effective for a system for forming, filling and packaging a package having a folded part, and not only can completely sterilize the folded part, but also has a wide range of measures to prevent secondary contamination. It has the advantage that it can be done from the sterilization process of the folded part and is relatively narrow.
