- a nozzle (not shown) is provided on the tip extension plug 41 side, and when the support hole of the slat moves to a position corresponding to each of the storage containers 11 supported by the tip extension plug 41, the nozzle When air is blown into each of the storage containers 11 from above, the storage containers 11 are moved to the slat conveyor 45 side, and are stored in the sleeves 12 previously inserted and supported in the support holes of the slats. Can be equipped.
- the container 11 and the sleeve 12 supported by the support holes of the slat are conveyed by a slat conveyor 45 and sent to a filling machine (not shown). After the liquid food is Takashi ⁇ by this charge Hama machine, container 1 I is tightly sealed with the lid 1 3 (FIG. 1) c
- FIG. 7 is a first process diagram of a packaging container forming method showing an embodiment of the present invention
- FIG. 8 is a second process diagram of a packaging container forming method showing an embodiment of the present invention
- FIG. 9 is a present invention.
- FIG. 8 is a third process diagram of the method for molding a packaging container according to the embodiment.
- 21 is a multilayer sheet
- 35 is a female type
- 41 is a tip extension plug-The tip extension plug 41 is disposed so as to face the female type 35
- a tubular extension cam 51 with a bottom opening to the front, a mouth 53 arranged at the center of the extension plug 41 at the center so as to be freely lifted, and a fulcrum 5 at the tip of the rod 53
- It has a cam blade 55 that is swingably mounted around 4.
- a plurality of the cam blades 5 ⁇ are disposed on the periphery of the ⁇ pad 53, and a cam follower below the fulcrum 54 is provided. It comprises a piece 55a and an extension piece 55b above the fulcrum 54.
- a cam surface 51a is formed which protrudes radially inward as it goes upward. Therefore, as shown in FIG. 8, when the rod 53 is lifted, the cam follower 55a of the cam blade 55 moves along the expansion cam 51, and the diameter gradually increases. The cam blade 55 is swung because it is located inward in the direction. On the other hand, the tip of the extension piece 55b is moved radially outward with the swing of the cam blade 55. During this time, the inside of the female mold 35 is evacuated through the hole 58 formed in the female mold 35.
- the receiving container 11 is formed into a well-balanced wall having a good thickness balance, a thin bottom and side portions, and a uniform thickness.
- the accommodation container 11 can be reduced in weight and airtightness can be increased.
- the present invention can be used for a packaging container containing liquid food and an apparatus for manufacturing the packaging container.
