製造される。(Prior Art) In a so-called peel-apart type or mono-sheet type instant film unit, a processing solution pod in which a developing solution (hereinafter simply referred to as a processing solution) is filled in a bag-like pod with four sides closed. Is fixed to the end of the unit, and when the unit is passed between a pair of processing liquid developing rollers after exposure, the pod is cleaved and the processing liquid stored therein spreads to a predetermined image forming area. It is supposed to be done. (See Japanese Examined Patent Publication No. 51-25734, etc.) The above-mentioned processing liquid pod material is a thin and deformable material accumulated, and is a layer made of polyvinyl chloride or a thermoplastic resin inert to the processing liquid and its vapor, It is a sheet-like product composed of three layers, a layer of lead or aluminum that does not allow the treatment liquid to pass through, and a paper layer for preventing deformation of the pod.
The pod material is used to manufacture the device as shown in FIG.

The processing liquid 12 is filled in the pod material 1 by a nozzle 11 which is a processing liquid filling means. A second seal portion 120 is provided in the transport path of the pod material 1, and the second seal portion 120 moves the pair of sealers 121 and 122 in the direction of arrow B to hold and press the pod material 1. The pod material 1 is heat-sealed in the width direction at regular intervals. The treatment liquid 12 is sent out from the nozzle 11 so that the liquid surface is located above the sealers 121, 122, and the sealers 121, 122 perform the heat sealing while pushing out the treatment liquid in the sealing portion. FIG. 7 is a perspective view of the sealers 121 and 122.

せてしまうおそれがある。(Problems to be Solved by the Invention) Heat sealing by the sealers 121 and 122 has three major sealing defects. As shown in FIG. 8, the pod material 1 comprises a polyvinyl chloride layer 1C, an aluminum layer 1B and a paper layer 1A from the inside.
If the heat-sealing due to is too weak or the treatment liquid in the seal portion is not sufficiently removed, as shown in FIG. 8 (a), the treatment liquid 12 is contained in the polyvinyl chloride layer 1C in the heat-sealing portion.
May enter and the processing solution may flow out. Also, when the heat-sealed portion of the polyvinyl chloride layer 1C during heat-sealing has a large flow, the flowing polyvinyl chloride layer
As shown in FIG. 8 (b), 1C may be collected and deformed at the end of the heat-sealed portion, causing cracks in the polyvinyl chloride layer 1C. When a crack is generated in the polyvinyl chloride layer, the treatment liquid 12 in the pod material 1 gets wet from this portion,
Treatment liquid 1 is generally a strong alkaline substance, so an aluminum layer
Erodes 1B and evaporates to the outside. Furthermore, if the treatment liquid 12 in the heat seal portion is not sufficiently removed during heat sealing, the treatment liquid 12 remains in the heat seal portion as shown in FIG. There is a possibility that the polyvinyl chloride layer 1C may have a hole and the processing liquid 12 in the pot material 1 may be evaporated by being vaporized (foamed).
一般にポッド材料のシールをするには十分な温度で溶融
し、十分な圧力で圧着させる必要がある。処理液が不在

液を排除してから接着させる必要があり、上記シール不
良の説明のように難しくなる。Generally, in order to seal the pod material, it is necessary to melt the pod material at a sufficient temperature and press it with a sufficient pressure. When the treatment liquid is absent, the treatment liquid adheres well, but when the treatment liquid is present, it is necessary to remove the treatment liquid before adhering the treatment liquid, which is difficult as described in the above description of the sealing failure.

することが困難であった。The invention of liquid infiltration (Fig. 8 (a)), cracks (Fig. 8 (b)), and foaming (Fig. 8 (c)) due to the above-mentioned heat seal failure is Depends on seal temperature. FIG. 9 (a) shows the case where the sealing time is 1.0 second, and the safety region in which the above-mentioned three problems do not occur is the range shown by the diagonal lines in the figure. When the manufacturing speed of the processing liquid pod is to be further increased, the sealing time is naturally shortened, and the safety region in that case is an extremely narrow range shown by the diagonal lines in FIG. 9 (b). FIG. 9 (b) shows the case where the sealing time is 0.1 seconds, but in such a conventional manufacturing apparatus, when trying to speed up the manufacturing of the processing liquid pod, the area where the heat sealing defect does not occur becomes extremely narrow, It was difficult to achieve high speed.

る。(Means and Actions for Solving the Problem) The processing liquid pod manufacturing apparatus according to the present invention includes at least one of a pair of sealers having a flat sealing surface for sealing the pod material filled with the processing liquid in the width direction. A plurality of recesses on the sealing surface, spaced apart from each other, are formed in the width direction so that the flat portion between the recesses at least opposes the flat portion of the other sealing surface. At the time of sealing, the polyvinyl chloride layer is made to flow in the direction of the recesses to satisfactorily remove the processing liquid from the portions overlapping with the recesses, and the flowed polyvinyl chloride is dispersed and absorbed in the direction of these recesses. It is intended to prevent the layer from cracking.

を良好に、かつ確実に行えるようになった。When the pod material 1 is held and pressed while heating the sealers 21 and 22 while being heat-sealed, the pot material 1 including the paper layer 1A, the aluminum layer 1B, and the polyvinyl chloride layer 1C.
The treatment liquid 12 filled in the inside is extruded from the heat-sealed portion. Among the treatment liquid 12, first, the treatment liquid in the portion overlapping the convex portion 22c of the sealer 22 is shown by a solid line in FIG. 4 (a). It is made to flow in the direction indicated by the arrow, that is, in the length direction of the pod material 1 (vertical direction in FIG. 4) and in the direction of the recess 22b. In addition, FIG. 4 (a), (b),
The hatched portion in (c) is the portion where the treatment liquid 12 is present. As shown in FIG. 3 (b), when the sealers 21 and 22 further approach and press the pod material, the treatment liquid 12 is completely removed from the portion overlapping with the convex portion 22c, and then the portion overlapping with the convex portion 22c is removed. The polyvinyl chloride layer 1C begins to flow in the direction indicated by the broken line arrow in FIG. 4 (b). As a result, the processing liquid 12 that has flowed into the portion overlapping the recess 22b is pushed out in the direction indicated by the solid arrow in FIG. 4 (b). As shown in FIG. 3 (c), the sealers 21 and 22 continue to approach each other and press the pod material to cause the polyvinyl chloride layer 1C to flow, and the flowed polyvinyl chloride layer is positioned so as to overlap with the recess 22b. Once in, the treatment liquid 12 in this portion is completely discharged and fused together. Therefore, as shown by the broken line arrow in FIG. 4 (c), the sealers 21 and 22 are brought close to each other to such an extent that the polyvinyl chloride layer slightly flows in the length direction of the pod material 1 from the portion overlapping the recess 22b to perform the heat sealing. If this is done, the treatment liquid is completely removed from the heat-sealed portion, so there is no possibility that the treatment liquid will enter the heat-sealed portion or the treatment liquid will not be completely removed and foaming will occur. At the same time, the flow of the polyvinyl chloride layer is dispersed in the portions corresponding to the respective recesses, so that the flow is concentrated in one place, the polyvinyl chloride layer is largely bent, and there is no inconvenience that cracks occur. As described above, in this apparatus, the heat sealing can be satisfactorily and surely performed by controlling the flow of the treatment liquid and the polyvinyl chloride layer.

理液ポッドの高速製造が可能となる。Therefore, even if the time required for heat sealing is shortened as compared with the conventional case, the performance of heat sealing is not deteriorated, and high-speed manufacturing is possible. For example, when the sealing time is 0.1 seconds, the range of liquid, intrusion, cracking, sealing pressure at which foaming does not occur, and sealing temperature is shown by the hatched portion in FIG. As is clear from FIG. 5, since the area where stable heat sealing can be performed is greatly expanded, it is possible to manufacture the processing liquid pod approximately 10 times faster than the conventional one.
