Abstract

PURPOSE:To manufacture a box type container which has no pin hole and which prevents leakage and deterioration of the contents, in the container for liquid made of a sheet material coated with a thermoplastic material at both faces. CONSTITUTION:A sheet belt material 1 coated with thermoplastic material at both faces is folded double to superpose both edges on transferring and heated to weld them so as to form a belt at every specified distance in the right angle against the transfer direction of the sheet belt material 1. After that, the center of the welded part is cut to form a nearly rectangular bag-form container 9 having an opening at one side thereof and the bag-form container 9 is widened from the inside to form a box type container 13. After a fluid has been charged from the opening, the ears 13a, 13b formed at the corners at the opposite side of the opening of the box type container 13 and the container surface on which the ears are applied, are heated by hot air to weld them with heat.

Next, the operation of the above box-shaped container manufacturing apparatus will be described. The box-shaped container 13 filled with the fluid and having the opening sealed is transported to the position P 0 by the carrier 33,
It is transferred to the container holder 51 with a pusher (not shown). The box-shaped container held by the container holder 51 is P 2 , P 3 , P 4 , P 5 , P 6 , P from the position of P 1.
It is conveyed intermittently to position 7 . Ears 13a, 13a, ears 13b, 13b formed at the corners of the box-shaped container 13
Is open to the outside at the positions of P 1 and P 2 as shown in FIG. When the box-shaped container 13 moves from the position P 2 to the position P 3 , elongated holes 58 provided in the pressers 57, 57,
Rods 59, 59 fitted to 58 are moved upward by a cam mechanism (not shown), and pressers 57, 57 are attached to the box-shaped container 1.
It rotates to the 3 side, and the ears 13a, 13a are slightly lifted. Figure 3 when the box-shaped container 13 reaches the position of the P 3, 6
The air cylinder 69 operates, the arm 64 rotates, and the tips of the L-shaped nozzles 62, 62 attached to the tips of the hot air heating devices 61, 61 are the ears 13 of the box-shaped container 13 as shown in FIG.

Here, from the tip of the nozzles 62, 62 to the ear 1
Hot air is blown onto the upper surfaces of 3a and 13a and the surface of the box-shaped container to melt the thermoplastic synthetic resin on the surface. At this time, since the inside of the box-shaped container 13 is filled with the fluid, heat is not transferred to the inner surface, and the thermoplastic synthetic resin on the inner surface does not melt. Further, the thermoplastic synthetic resin on the surfaces of the upper surface of the box-shaped container 13 and the upper surfaces of the ears 13b and 13b is also melted by the hot air blown from the tip of the hot air heating device 73. When this melting process ends, the air cylinder 69
Is activated, the arm 64 is rotated, and the hot air heating devices 61, 6
The nozzles 62, 62 are separated from the box-shaped container 13 together with 1, and the box-shaped container 13 becomes movable.

Then, when the box-shaped container 13 moves from the position P 6 to the position P 7 , the cam mechanism (not shown) moves the rods 59, 59 downward, and the pressers 57, 57 are separated from the box-shaped container 13. Then, the ears 13a, 13a are released from being pressed against the container surface. Also, the ears 13b, 1
The pressing on the container surface by the crimping device 3b is also released. When the box-shaped container reaches the position P 7, the air cylinder 38 shown in FIG.
The box-shaped container 13 is rotated from the container holder 51 to the discharging conveyor 40, and the discharging process is performed. The ear 1 formed on the upper corner of the box-shaped container
The process of press-bonding 3b and 13b to the container surface is not limited to the process performed when the box-shaped container 13 is transported around the rotating plate 50 as in the above-described embodiment, but the carrier 33 is used.
Alternatively, it may be performed when the box-shaped container 13 is conveyed on the discharge conveyor 40.
