う点でも満足のゆくものでなかった。As is well known, it is generally necessary to sterilize beverage liquids before filling them into containers, and this treatment is usually applied to the inner walls of the containers as well. However, the simplest sterilization method is to treat the liquid at high temperature (approximately 93°C), then fill the container with the liquid at high temperature and then seal it, thereby simultaneously sterilizing the liquid and the inner wall of the container. be. This method is abbreviated as "hot filling" in this specification, but when hot filling is carried out, the following problems arise. After hot filling, the lid is sealed and hermetically sealed, and when it is cooled, the volume of the liquid in the container contracts, the vapor in the container solidifies, and the volume of the sealed air increases. Due to the isobaric contraction, the volume of the contents decreases, creating a so-called reduced pressure state. If the saizushi itself is made of a highly rigid material, such as a steel can, it can withstand the reduced pressure inside the edge, but if it is made of relatively low-rigid plastic or paperboard laminated with plastic, Otherwise, there is the problem that the container will dent as the pressure decreases, making it look unattractive. Conventionally, in an attempt to solve this problem, the top part of the container (4
Part 11) is coated with a thin At foil that is relatively easily deformed or an At foil with annular folds, and this part is dented due to volumetric contraction, or as shown in Japanese Patent Application Laid-Open No. 56-23461. In this case, the wall of the container is made of a double material, for example, paperboard and polyethylene, and a large part of the wall is glued (leaving a part of it as a non-bonded part), and only the inner polyethylene in the non-bonded part is depressurized. There are known cases where it was sometimes recessed inward. However, in the former method, the top portion is significantly recessed, so when attempting to provide easy opening to this portion, there is an inconvenience in that it is limited. Furthermore, since the top portion is thin, there are concerns about impact or dropping, and the impact resistance is also unsatisfactory.
また後者の方法はガスバリヤ−性に問題を生じたシ、内

であるかのような体裁となる等、不満足な面があった。The latter method also had some unsatisfactory aspects, such as problems with gas barrier properties and uneven inner recesses, giving the container the appearance of an incomplete container when viewed from the inside.

In other words, the deformation of the container due to the volumetric contraction is absorbed exclusively by the change in the shape of the inner bag, and the The temporary seal on the bottom plate of the outer shell handles the air flow required during the process, and the bottom plate of the outer shell is permanently sealed after the inner bag is deformed to maintain its original functions as a container, such as pressure resistance and water resistance. It is designed to make full use of the

ゆる非接着部(4a)が形成されるのである。Proceeding to a concrete explanation of an example of the apparatus used when temporarily sealing and permanently sealing the bottom plate (3) of the outer shell (1) as described above, as clearly shown in FIGS. 4 to 6, An adhesive mechanism is vertically provided in the center of the base Ql) that can be raised and lowered through the base, and an adhesive mechanism that can move up and down in the radial direction about the axis of the adhesive mechanism is provided on the upper surface of the base. A pressure bar Q:ll is provided. The adhesion mechanism 0 includes a vertical rod a9 having a guide member I having a dish-shaped cross section, and a push-up rod a in the shape of a shaft provided so as to surround the vertical rod 0!19.
Q, and a presser piece aD that can be expanded and contracted between the pusher rod and the plate-shaped guide member Q4), and these act as follows to seal the bottom plate of the container. . That is, the molded container (C) is placed on the ring-shaped container placement surface (lla) at the center of the base Ql), and then the vertical rod 0!19 is moved to the position shown in FIG. and the push-up rod αe are moved upward, and at the same time, the pressure bar Q3 is also moved in the radial direction. In such a case, as is clear from FIG. 6, the plurality of radially arranged pressing pieces aη are pushed up from below via the push-up rod θe, but at that time, the The sliding surface (17 m) is guided by the tapered surface (14a) of the guide member 0 waiting above it, and resists the elasticity of the spring (17b) attached to each pressing piece 07). and expand in the radial direction. Since the pressurizing part (17c) is provided on the outer periphery of the pressing piece aD, the pressurizing part pressurizes the bottom plate part of the container from the inside toward the outside, while the Pressure bar 03
presses the bottom plate portion inward in synchronization with the pressing piece aη. Since the bottom plate of the container is thus subjected to pressure from both the inside and outside, if a pressure-sensitive adhesive has been applied to the bottom plate, for example, the bottom plate will be instantly bonded as a result of the pressurizing operation. In addition, if a heat-sensitive adhesive is applied to the bottom plate part or a heat-melting plastic film or the like is laminated, the pressurizing part (17c) of the pressing piece a7) constituting the adhesive mechanism Q3 An electric heater is built in in advance, and when the pressing piece presses the bottom plate part, it heats the bottom plate part at the same time to perform thermal bonding. The bottom plate of the container is sealed by pressure-sensitive adhesive or heat-sensitive adhesive as described above.
As shown in the figure, the pressing piece an and the pressure bar that perform the sealing action are divided in the radial direction, and as a result, the bottom plate of the container is locally bonded along the circumferential direction, resulting in a so-called non-bonded state. A portion (4a) is formed.
