発が望まれていた。(Problems to be Solved by the Invention) In heat seal molding of a container having a spout, the energy required is naturally different between the part where the spout and the film are welded and the part where the films are welded together. In conventional molds with one-piece structure, when the heat-sealing temperature is matched to the welded part of the spout and the film, the welded part of the films may melt too much, or vice versa, making it impossible to produce a defect-free container. There were problems such as inability to manufacture efficiently. As mentioned above, with conventional molds that have an integral structure, it is difficult to control the temperature in the part where the film and spout are welded together, and in the part where the films are welded together, especially when the film is a single-layer product made of polyolefin resin. Since defective products are likely to occur, there was a desire to develop a mold that could control temperature.

The mold has a structure in which a part for welding the film or sheet, etc. and the spout, and a part for welding the film or sheet, etc. together on the side of the spout, which is heated at a lower heating temperature than the same part, are provided. is used as a means to solve problems.

Marks (not shown) for positioning with the phototube 3 are printed on the side of the film 1a at regular intervals, and these marks are detected by the phototube 3 to indicate that the film 1a has been conveyed to a predetermined position. Once confirmed, the film 1a is stopped and the bottom portion is cut by the cutter 2 to form the container body 16. This part will also become the opening of the next bag. The cut bottom portion may be seal-welded in advance on the inner side of the cut portion, or the same portion may be seal-welded at the same time as cutting or separately at an appropriate position. Next, the mouth 20 of the container body 16 is opened using the suction device 4 as shown in FIG.

る。On the other hand, the lower mold 5b is provided with a mold lO having a surface 10a for welding 18 the film of the mouth portion 20 and the spout 17, and a heat insulating plate 12
A split mold 11.11 is attached having a surface 11b for welding 19 the films attached to the lower mold 5b via the lower mold 5b as shown in FIG. This mold 11 needs to be kept at a lower temperature than the mold 10, and for this purpose cooling holes 14 are formed. This cooling hole 14 may be left open to cool by natural convection of air, but it may be connected to an air source or a water source with a pipe to actively flow cooling air or circulating water. It's okay. Further, although the mold 11 is provided only on the lower mold 5b, it may be provided only on the upper mold 5a or both. 15 is a heater for the upper mold 5a and the lower mold 5b.
The thermocouple 13 is inserted through the main body of the film in the width direction of the film. Further, 6 is a cylinder that moves the mold 5 back and forth. Note that the spout 1 shown in FIG.
7 has a spindle shape when viewed from the front, but various shapes such as oval, rectangular, and circular can be adopted for this, and the sealing mold for molding can be changed according to the shape of the spout. .
次に以上の如く構成された実施例について作用を説明す

される。The seal mold 5.5 is then advanced by the cylinder 6. The mold 5 is a mold 9 in the high temperature part heated by the heater 15.
, 10 and the heater 15.
It consists of 11 parts of the split mold, which has a low temperature due to the heat dissipated from the mold. Now, the mold 5, that is, the upper mold 5a and the lower mold 5b, moves forward to remove the film in the opening 20 from the surfaces 9a and 10 of the molds 9 and 10.
At the same time as the film is pressed against the spout 17 by the film 10a, the film is welded to the spout 17 by the heat. Further, the film on both sides of the pouring hole 17 is sandwiched between the surface 9b of the mold 9 and the surface 11b of the split mold 11, and the film is sandwiched between the surface 11b of the split mold 11, which is lower temperature than the surfaces 9a and 10a, and the surface 11b of the split mold 11, The films are welded together with the surface 9b of the mold 9 at an appropriate temperature without over-melting.

The welded parts of the films on the side of the spout are also sandwiched and welded by a surface that is cooler than the part of the mold where the film and the spout are welded, so the film does not melt too much. Both parts can be welded at the optimum sealing temperature, resulting in a container with a good finished appearance and a defect-free spout.
