である。BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in more detail with reference to the other drawings. FIG. 4 is an enlarged view of the chamber of the hot air heater for sealing a liquid paper container according to the present invention, which is shown in three views. FIG. 2 is an overall view of the hot air heating device 20 for forming a liquid paper container, and the chamber 13 in this figure is connected to the tip of the blower pipe 11 via a mounting plate 12 in the same manner as in the conventional case. However, the six blowing plates 14 provided on the outer wall surface of the chamber 13 are not vertical unlike the conventional one, and the blowing plates 14 for heating the ribs 4 of the roof panel 2 spread slightly downward as shown in the side view. Blowout plate 1 for heating the ribs 4 of the folding roof 3
In No. 4, a twist is formed as can be seen from the bottom view.
This is a shape obtained by arranging the blowing plate 14 so as to maintain a predetermined uniform interval with respect to the inner surface of the half-opened hexagonal rib 4 of the liquid paper container 10 shown in FIG. 1B. This distance is preferably in the range of 5 to 8 mm, and is preferably 6 to 7 mm. Fine blowing nozzles having a hole diameter of 0.7 to 1.5 mm are arranged at the same density on each blowing plate 14. This array pattern has ribs 4 facing each other.
It has the same shape as. 28 from this blow nozzle
By blowing hot air of 0 to 390 ° C. at a wind pressure of about 150 Aq mm and heating for 1 to 3 seconds, the inner surface of the annular belt-shaped rib 4 can be uniformly blown at an appropriate temperature. By taking the above means, the rib 4
It is difficult to cause temperature variations on the inner surface of the sheet, and as a result, it is possible to solve problems such as peeling of the ribs 4 due to defective adhesion and liquid leakage due to damage to the laminated material in an excessively heated portion.

ン通りの加熱を精度良く繰り返し行うことができる。The hot air heater 20 for sealing a liquid paper container according to the present invention acts on the liquid paper container 10 that is intermittently transferred in the positional relationship shown in FIG. 2, and should be heated with the chamber 13. The positional relationship with the four ribs is accurately maintained by a carton basket, a cooling guide (not shown) that supports the half-open folding roof panel from below, and the like. Further, since the hot air blown out from the fine blowout nozzles of the blowout plate 14 travels substantially straight, it is possible to accurately and repeatedly perform heating according to the arrangement pattern of the nozzles.

As a result of the heating under the above conditions, peeling due to poor heating and scorched portions due to excessive heating were not seen, and the top seal of the rib portion was extremely stable. It was also possible to use hot air as necessary and sufficient.
