The Ministry of Economic Affairs, Central Bureau of Standards, Beigong Consumer Cooperative Printing ... 297012 A7 __________7__ V. Description of the invention (1) The scope of the invention The present invention relates to a method of filling packaging containers. Background and Overview Conventional packaging containers made of resin are usually used to fill liquids, such as liquid foods, and filled containers are sealed with a lid. Usually this is done with a rotary filling device-this kind of filling device contains a turntable on which the container can be placed and is driven by the rotation of the turntable 3 This filling device also contains an injection station 'and a Hezhan. At the injection station, liquid food will be injected into the container through the opening at the top of the container. At the sealing station, the top end of the grain container will be sealed by a cover. After the container placed on the turntable is filled with liquid food at the filling station, it will be moved to the sealing station with its top still open. Since the turntable rotates at a relatively high speed to speed up its filling operation, the liquid food contained in the container may sometimes come out of the opening due to factors such as vibration. In order to avoid splashing and related problems, it is a common practice to use a container whose top is j at a given height above the liquid food level filled in the container so that the trough has a head in its upper half space. For complete filling, a plug-in lid member is generally used, that is, a lid that can be partially inserted into the packaging container. j is the method of filling the packaging container described above, which requires a considerable degree of accuracy without filling in order to obtain a complete filling. In addition, the container is fully filled with a plug-in lid to seal it. The -4- paper size in the container is suitable for Guanjia County (〇νχΤα1ϊϊ # 7Τ7 ^ χ 297 / > t) ~ ~~ -----

Description of the invention (2) Pressure will increase due to liquid food being squeezed and overflowing. In addition, when sealing with a plug-in lid member, the resin constituting the container often melts, which reduces the volume of the container. This will also cause an increase in the pressure inside the container. As a result, greater force needs to be applied to the sealing part and other parts of the container. An object of the present invention is to provide a method of filling a packaging container, which can overcome the above-mentioned problems of the conventional packaging container filling method, which can reduce costs, and does not cause excessive force on the sealing portion and the whole of the container. According to one aspect of the present invention, a method of filling a packaging container injects a liquid food into a container made of resin, the container has an opening at its top end, and a deformable portion is provided on its side wall The internal volume becomes adjustable, a cover is provided on the top of the container, and a sealing device can be lowered from a position above the cover for the upper end of the container Cover and seal it. According to another aspect of the present invention, during the sealing process, the deformable portion of the container deforms to raise the surface of the liquid food to a height adjacent to the top of the container. Printed by the Staff Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The container of the present invention is placed on a filling station of a turntable and filled with liquid food, for example When the portion is not deformed to reduce the volume of the container, for example, by pushing up the deformable portion of the bottom surface portion of the container, there is a space between the liquid surface of the liquid food and the top of the container. The container is then moved to a sealing station on the turntable, and the top of the container is sealed there. Since the space between the liquid level of the liquid food and the top of the container will be maintained when the container moves from the filling station to the sealing station, the liquid will not splash out of the opening due to vibration, even when the turntable is This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of invention. (3; —-_ Rotate with extreme degrees. Such an overall filling is done. At the first stage, the industry can enter the seal at a fairly fast speed, and the deformable part will be prepared. For example, it is pushed upwards, so that the liquid level of the liquid food rises to Le., H ^ to Near the height of the top of the container and when the container is closed with a lid, it will be pushed in the opposite direction, such as downward. But because the container will form a negative pressure ... The pheasant is deformable The part will be maintained in the deformed position, for example, the bottom part is kept moving upward; placed on. When the container is not completely sealed by the lid, the negative pressure in the container will "dissipate, so that the The deformed part is moved back to the undeformed Put it on, for example, its r moves back to the down position. Therefore, it can check whether the deformable part is in the deformed position, for example, its column # 兵 尾 面 邵 份 系 is in the upward movement position , Knowing that the container ^ is properly sealed. ^ Bu, forming a negative in the container can prevent excessive force on the sealed part of the container when the container is sealed with the lid, such as the resin fusion site.

For the sake of convenience, the bushing U (Figure 12) is not shown in these figures to illustrate the steps of this method. 1々 According to this method, the container η will be sent to the turntable (not shown) (iv) and driven by the rotation of the table to the injection station. As shown in FIG. 5, in the injection station 7 an input pipe 31 with an injector (not shown) is provided above the Rongqin to supply a fixed amount of liquid food to the container ⑽. The liquid food is preferably injected so that a space δ can be formed between the liquid surface and the upper end of the heart. The container is then transferred to the lid placement station, where a lid applicator (not shown) is used to place a lid 13 above the container u, as shown in FIG. Thereafter, the container 11 is transferred to the sealing station, where, as shown in Figure 7, and the lid U will be placed on the container "or sleeve 12, if any, on the upper edge. (Most Fortunately, the flange part visible in FIG. 2 is in the sealing station. A sealing device 32 is provided above the cover 13, and a pusher 33 is provided below the cover 13. In the container When the injection station is moved to the sealing installation station, the head space formed in the upper half of the container can prevent the liquid food contained in it from vibrating even when the turntable rotates at a relatively high speed It overflows from the opening. Therefore, it can be filled at a high speed.

Description of the invention (10) The sealing device 32 will then descend, as shown in FIGS. 1 and 8, to press the peripheral edge of the lid 13 against the upper edge of the container Π , And then the container 11 is sealed with the lid 13. In this case, the pusher 33 Will move upward to push the flat portion μ of the bottom surface portion 1 lc of the container U. Therefore, the bellows portion P1 will be elongated to move the flat portion P2 upward, thereby raising the liquid level of the liquid food to the container 11 At the upper end of the sealing device, the sealing device then moves upwards, and the pusher 33 moves downwards, thereby completing the sealing container Π ′ of the lid 13 as shown in FIG. 9. After moving the pusher 33 downward At this time, the flat part p2 of the bottom part 1 lc will be forced to move downward. However, < _-Since the container 11 is sealed by the lid, a negative pressure will be formed in the container 21, and the flat part P2 will be maintained at its upward position. But when the lid 13 fails to seal the container 11 perfectly, no negative grace will be formed in the container, and the flat part P2 can move downward. Therefore , By checking whether the flat part P2 remains in its upward position, it will be able to determine whether the sealing of the container is correct. Since the negative pressure is formed in the container 11, it can prevent the resin constituting the lid from melting At that time, there is too much force acting on the sealing part and the container, or in the sealing There is excessive force acting on the container.
