Description of the invention (1) The present invention relates to a method for filling plastic bottles. More specifically, but not exclusively, this method is generally suitable for aseptic bottling processes. In particular, a method for filling a bottle and sucking air out of the bottle by inserting a filling / suction nozzle at a bottle mouth of the top of each bottle; the method also involves forming an air-tight opening so that when the bottle is full, The pressure inside the bottle is lower than the pressure of the external environment. Various methods of this kind are known: for example, this type includes forced suction grapefruit isobaric filling and, more generally, the pressure inside the bottle is different from the environment outside the bottle during the filling process. In the above-mentioned method, a sealing ring made of an elastic material mounted on a base forming a filling member is used to generate a seal around the bottle mouth. The leading edge of the seal ring is designed to hermetically contact the top edge of the mouth of the bottle, as is known ' When the seal ring is deformed by the edge of the bottle mouth, the required seal is achieved. However, the known methods described above still have certain limitations and disadvantages. First of all, the seal ring is easy to assemble quickly, because the kind of manufacturing material needs to be soft and breathable, and because of the high number of operating cycles. Inside the filling machine, it needs frequent replacement of the sealing ring, which causes the machine gf to stop operating. This problem is exacerbated by the heat transfer generated during cleaning and disinfection of the aseptic filling machine and by the thermal expansion that the seal ring experiences even causing it to fall off the base. Furthermore, the use of sealing rings can cause serious problems in making bottled products contain germs. This is because only the product injected into the bottle can easily enter the gap between the seal ring and its base and be trapped there. Known cleaning and disinfection actions are easy to miss.

Description of the Invention (2) This gap 'will make the product corrupt and cause the growth of germs. The mechanism action and thermal expansion of the seal ring may cause the contaminated material to be trapped in the removed gap, thereby contaminating the bottled product. The purpose of the present invention is to overcome the limitations and disadvantages of the above-mentioned known techniques by filling the plastic bottle in a sealed condition. It is a section that is formed by the mouth of the bottle closely against the integral part of the nozzle and is less likely to deform than the bottle mouth. The head conical surface creates a seal. The advantage of the invention in the seal theory is that it allows # to fill a large number of bottles in a secret recording state without stopping the filling equipment and at the same time ensuring a perfect seal. The advantage is that even the cleaning and disinfection of filling equipment, which involves sudden changes in temperature and subsequent swelling, ensures perfect sealing. An additional advantage is that it allows filling under any completely aseptic seal. The purpose of this issue is to make the available devices simple and inexpensive and to implement the methods under discussion. The advantage of this month is that it provides a device that maintains a perfect seal during operation and is free of contaminated deposits. Another advantage is that it provides a self-centering device, in other words it can automatically correct any slight misalignment between the mouth and the neck of the plate. The above and other objects and advantages are all achieved by the invention in question 'It is characterized by the following patent application items. The features and advantages of the advanced month will be described in detail by the following preferred specific examples of the present invention, with additional drawings to illustrate non-specific examples.'

Figure 2 shows the nozzle of Figure 1 and the bottle mouth of a bottle of a different form than the one shown in Figure 1. With reference to the above figure, the number 1 represents the entire nozzle of the plastic bottle. Nozzle 1 is especially used for aseptic Filling machine for filling plastic bottles under aseptic conditions Each plastic bottle has a bottle mouth on its top. The bottling machine may include a filling rotary disc, known per se and not shown in the drawing, which rotates about a vertical axis of rotation and contains a plurality of nozzles arranged around the axis of rotation The bottle is fed to the rotary disk by the feeding route. The feeding route is also known by itself and is not shown in the drawing. It can rotate the rotary disk while filling the bottles that enter one by one through different nozzles. Each nozzle 1 has a lower end of the bottle mouth 2 which can be inserted into the bottles 3a, 3b. As shown in Fig. 1, the nozzle 1 can be used for a bottle 3a made of polyethylene, or as shown in Fig. 2 for a PET made of PET. Bottle 3b, or other types of bottles, as long as the top of the bottle has a slightly deformable mouth. Nozzle 1 refers to the same type that can dispense liquid to fill the bottle 3a or 3b and simultaneously extract the air contained in the bottle. Each nozzle The lower end of 1 has at least one outlet for injecting liquid and an inlet for extracting air.

Description of the invention (4) It has a convex ring 4 protruding outward, which is a known type of ring assembly used to hold and handle the bottle 3b 5 Grasp the mouth of the bottle 2. According to the present invention, each nozzle has a flat head conical surface 6 that tapers downwards. The larger diameter of the surface 6 is larger than the inner diameter of the bottle mouth 2, and the shape of the frustoconical surface 6 makes it tightly fit the upper edge of the bottle mouth 2 of the bottle. The frusto-conical surface 6 is more rigid than the bottle mouth 2 of the container. The flat-cone conical surface 6 is especially made of metal (e.g. stainless steel). As the example shown in the figure, the flat cone surface can be formed by the outer surface of the nozzle body; however, the frustoconical surface may be formed on the surface of the nozzle 1 by additional application materials (by inlaying) ceramic or other Similar way). All the same, it is preferred to avoid any gaps, cracks, depressions or the like between the nozzle and any material that can be attached to form the frusto-conical surface 6 or the like, and the filler particles may sink and foul. The mode of operation of the device under discussion will be described below: Bottles 3a and 3b enter the filling carousel one by one in a known manner, which receives and advances the bottle around the path surrounding its filling. The bottle mouth 2 of each bottle is moved upward to insert the corresponding dispensing / suction nozzle 1. Any irregularities between nozzle 1 and mouth 2 will be corrected automatically. During filling, an air-tight seal is formed around the bottle mouth 2 so that the pressure in the bottle is lower than the pressure of the external environment due to the result of suction. The seal is produced by the top edge of the bottle mouth 2 abutting against the conical surface of the flat load head integrated with the nozzle 1. The edge of the bottle mouth 2 is pressed against the conical surface of the flat load head of the nozzle 1 with a specific pressure, and the bottle mouth 2 made of plastic is flatter. ---- Order --------- Line C, please read the notes on the back first! ^ This page)

Description of the invention (5 > The conical surface of the carrier is easily deformed, and the slight elastic deformation of the bottle mouth is enough to ensure a perfect seal around the bottle mouth. Due to this seal, it can be effectively extracted Air. When the filling process is completed, the bottle is easily separated from the nozzle by moving the bottle downward. The tapered angle of the frusto-conical surface 6 allows the nozzle 1 to easily penetrate the bottle mouth 2 and allows the subsequent nozzle 1 to pass through. Bottle mouth 2 is detached. It is also important that the connection between the frusto-conical surface 6 and bottle mouth 2 does not cause any permanent deformation of the latter. In any case, it is found that it can produce an effective seal without damaging the bottle mouth. More specifically, a tapered angle The selection is based on the deformation ability of bottle mouth 2: Generally speaking, the greater the deformation ability, the larger the tapered conical surface 6 is, the greater the angle of the taper is. On the contrary, as the bottle mouth 2 is very hard, it is recommended to use the corresponding shallow cone. According to the present invention, The pressure drop in the bottle during filling requires that the tightness of the seal be temporarily deformed when the edge of the bottle is pressed by a relatively hard and non-deformed frustoconical surface. Cheng a The employee cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs has cracked so there are no soft, deformable components that can withstand a large number of fatigue cycles, such as the rubber seal ring commonly used in this case. In the examples discussed later, its function is to provide a deformable seal. The element is only deformed once in a non-permanent manner ^ The present invention can accept several modifications to the practical nature of the detailed structure without departing from the following patent protection parks for invention concepts.
