In FIGS. 1-3, since the double structure lower heat seal area | region 203a, 203b is formed over the width direction full length of the medical soft container 1, a part of double structure lower heat seal area | region 203a, 203b is formed. The lower end portions 41a and 41b of the opening / closing operation portions 40a and 40b are configured. The double-structure lower heat seal regions 203a and 203b are, for example, regions that are only directly below the remaining portions 403a and 403b of the opening / closing operation portions 40a and 40b, that is, the lower end portions 41a and 41b of the opening / closing operation portions 40a and 40b. It may be formed only. In this case, the entire double structure lower heat seal regions 203a and 203b constitute the lower end portions 41a and 41b of the opening / closing operation portions 40a and 40b. Further, each of the double structure lower heat seal regions 203a and 203b may be a heat seal region formed intermittently along the entire length or a part of the width direction of the medical soft container 1.

  Each of the opening / closing operation units 40a and 40b has insertion paths 404a and 404b for inserting a finger, and has a loop structure that is paired with the opening interposed therebetween. Since the upper portions 402a and 402b of the opening / closing operation portions 40a and 40b are disposed above the opening 22, the fingers are inserted into the insertion paths 404a and 404b, the fingers are moved away from each other, and the top sheet 2a in the opening 22 When the back sheet 2b is pulled apart to open the opening 22 of the medical soft container 1, the finger can be placed near the upper end 22a of the opening 22, so that the top sheet 2a and the back sheet 2b are pulled apart. The force acts on the opening 22 efficiently. For example, the length of the upper portions 402a and 402b of the opening / closing operation portions 40a and 40b in the vertical direction is such that at least a portion of the extending portions 4012a and 4012b adjacent to the opening 22 is orthogonal to the top sheet 2a and the back sheet 2b. If it is set so that it can be oriented in the plane direction, the force that separates the top sheet 2 a and the back sheet 2 b acts more efficiently on the opening 22. In addition, since the insertion paths 404a and 404b are large, the operating range of the fingers inserted into the insertion paths 404a and 404b in the insertion paths 404a and 404b is wide. Therefore, the finger in the insertion paths 404a and 404b can be easily moved, so that the opening / closing operation unit can be easily operated by the finger. Therefore, in the medical soft container 1 of the present invention, the opening can be easily opened largely.

  As shown in FIGS. 1 and 2, the length X2 in the direction parallel to the central axis 400 of the upper portions 402a, 402b of the opening / closing operation portions 40a, 40b (however, the upper portions 402a, 402b are the upper end heat sealing region 4013a of the opening / closing operation portion 40a). , 4013b, the length of the opening / closing operation unit upper end heat seal area 4013a, 4013b is removed) by inserting a finger into each of the insertion paths 404a, 404b to open the opening 22 of the medical soft container 1 At that time, as much as possible, the finger can be placed as close as possible to the upper end 22a of the opening 22, and the force for separating the top sheet 2a and the back sheet 2b in the opening 22 can be efficiently applied. 1 mm or more and 30 mm or less are preferable, and 5 mm or more and 15 mm or less are more preferable.

  Length X1 in the direction parallel to the central axis 400 of the opening / closing operation units 40a, 40b (however, when the upper portions 402a, 402b include the opening / closing operation unit upper end heat seal regions 4013a, 4013b, the opening / closing operation unit upper end heat seal region 4013a, The length of the portion excluding 4013b is preferably 20 mm or more and 100 mm or less, more preferably 30 mm or more and 70 mm or less, because two or more fingers can be inserted into the opening / closing operation units 40a and 40b.

  The material of the top sheet 2a and the back sheet 2b constituting the flexible bag member 2 is not particularly limited, and for example, a conventionally known soft resin sheet used for a medical soft container can be used. Specifically, for example, a single layer sheet made of vinyl chloride resin, polyethylene, ethylene-vinyl acetate copolymer, polyester, polybutadiene, polypropylene, polyamide, ethylene-methacrylate copolymer, or the like, or two layers of the above single layer sheet The laminated sheet laminated | stacked above is mentioned. Specific examples of the layer structure of the laminated sheet include nylon / polyethylene, nylon / polypropylene, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, nylon / polypropylene / polyethylene, and the like. Or even a laminated sheet (for example, biaxially stretched polypropylene (OPP) / unstretched polypropylene (CPP)) in which the same kind of resin having different grades (for example, film forming method, mechanical properties, or composition) is laminated. Good. It is preferable that the surface on the side to be heat-sealed is made of a material having easy heat-sealability (for example, polypropylene). The thicknesses of the top sheet 2a and the back sheet 2b are not particularly limited, but are, for example, about 0.1 to 0.6 mm. It is preferable that the top sheet 2a and the back sheet 2b have translucency (or translucency) because the liquid material in the housing portion 21 can be visually recognized from the outside. More preferably, the top sheet 2a and the back sheet 2b are transparent.

  The material of the discharge port 3 is not particularly limited, but a material harder than the material of the top sheet 2a and the back sheet 2b is preferable. Specific examples include cyclic polyolefin, polycarbonate, polyethylene terephthalate, polypropylene, polyethylene naphthalate, EVA (ethylene vinyl acetate copolymer), and the like.

  The usage method of the medical soft container 1 of this embodiment is demonstrated.

  As shown in FIG. 6, the soft medical container 1 can configure a nutrient supply system 90 by connecting an infusion set 91 to the discharge port 3, for example. The infusion set 91 includes a flexible tube 92 having one end connected to the discharge port 3, a drip tube 93 and a flow rate regulator 94 provided on the flexible tube 92, and the other end of the flexible tube 92. A connector 95 provided on the connector 95, a connector cover 96 that covers the connector 95, and the like. The drip tube 93 visualizes the flow rate of the liquid material flowing through the infusion set 91. The flow rate regulator 94 presses the flexible tube 92 to change the flow path cross-sectional area thereof, thereby enabling the flow rate adjustment of the liquid material flowing through the infusion set 91. The connector 95 is connected to a tube (not shown) inserted into the patient's nasal cavity or vein. However, the nutrient supply system of the present invention is not limited to the configuration shown in FIG. 6. For example, the nutrient supply system can be obtained by combining any conventionally known infusion set with the medical soft container 1 of the present embodiment. It may be configured.

  First, the flow rate regulator 94 is operated to crush the flexible tube 92 and close the flow path. In this state, as shown in FIG. 4, the left thumb is inserted into the insertion path 404a of the opening / closing operation unit 40a, and the other fingers (index and middle fingers in FIG. 3) are inserted into the insertion path 404b of the opening / closing operation unit 40b. Insert and hold the soft medical container 1 with the left hand. If the thumb is inserted into the insertion path 404a and the other finger of the left hand is inserted into the insertion path 404b, the opening 22 can be freely opened and closed by bringing the thumb and the other finger of the left hand into and out of contact.

  Next, a liquid (for example, infusion) in a cup (not shown) held with the right hand is poured into the opening 22 while holding the soft medical container 1 with the left hand while the opening 22 is opened.

  Since the thumb and other fingers of the left hand are inserted into the insertion paths 404a and 404b, and the upper portions 402a and 402b of the opening / closing operation portions 40a and 40b protrude above the opening 22, respectively, The other finger of the left hand can be placed near the upper end 22a (see FIG. 4) of the opening 22, and preferably the opening 22 is a plane perpendicular to the central axis 1a at the upper end 22a of the opening 22. Since at least the extended portions of the opening / closing operation portions 40a and 40b can be oriented in substantially the same direction, the portion adjacent to the opening portion 22 of 4012a and 4012b can be oriented. The container 1 can be stably held. Therefore, the possibility that the soft medical container 1 is dropped or the opening 22 cannot be sufficiently opened and the liquid material is spilled is reduced. Therefore, the mental and physical burden on the operator in the operation of injecting the liquid material into the medical soft container 1 is reduced.

  In addition, when the wrist joint of the left hand is at a natural angle, the front of the medical soft container 1 faces the operator, so that the scale 25 attached to the front can be easily visually confirmed. Further, the scale 25 is not hidden by the left hand or the like.

  After the liquid material is injected, the zip 23 is engaged to close the opening 22.

  In this way, the medical soft container 1 filled with the liquid material is suspended on a stand or the like using the suspension holes 27a and 27b of the suspension portions 26a and 26b disposed above the opening portion 22. . The medical soft container 1 is suspended so that its central axis 1a is substantially parallel to the direction of gravity and the discharge port 3 is at the lowest position. Connect the connector 95 to the tube inserted in the patient and open the flow regulator 94. Thereby, the liquid substance in the medical soft container 1 can be administered to a patient. Since the discharge port 3 is positioned at the lowest position, almost no liquid material in the medical soft container 1 flows out.

  Since the said soft medical container 1 can be manufactured with one manufacturing line so that it may explain in full detail below, according to this invention, manufacturing cost can be suppressed.

  Next, a method for manufacturing a soft medical container according to Embodiment 1 (hereinafter abbreviated as “Manufacturing Method of Embodiment 1”) will be described with reference to FIGS. 7A to 7H. For convenience of explanation, the upper side of the paper surface of FIGS. 7A to 7H is defined as “upper side”, and the lower side of the paper surface is defined as “lower side”. The “upper side” is also called “one end side in the width direction” of the long body. Moreover, in FIG. 7A-FIG. 7H, the outline of the medical soft container is described with the dashed-two dotted line for easy understanding. Moreover, in FIG. 7A-FIG. 7H, a dot is displayed only in the heat seal area | region in the area | region cut out as a medical container in (3rd process) for easy understanding. However, this does not exclude the fact that heat sealing is performed on an area that is discarded along with the cutting of the medical container. Moreover, in order to make it easy to refer to the drawings, reference numerals are shown in parentheses in the following description of the manufacturing method of the first embodiment.

The manufacturing method of this embodiment includes the following first to third steps.
(1st process) Long body A (2A) (refer FIG. 7C) of a surface sheet (2a) (refer FIG. 1), and elongate body B (2B) (refer FIG. 7F) of a back surface sheet (2b) (refer FIG. 2) (FIG. 7F) Reference).
(2nd process) After superimposing the elongate body A (2A) of the surface sheet (2a) and the elongate body B (2B) of the back surface sheet 2b, the outer peripheral heat seal region (24 ).
(Third step) At least a region surrounded by the outer peripheral heat seal region (24) from the laminate of the long sheet A (2A) of the top sheet and the long body B (2B) of the back sheet is a medical soft container. Cut out as (1).

(First step)
[Formation of long sheet A (2A) of surface sheet]
In the first step, as shown in FIG. 7A, the long sheet II (202A) of the inner sheet (202a) and the outer sheet are formed to form the long sheet A (2A) (see FIG. 7C) of the top sheet. A long body I (201A) of (201a) is prepared. The arrow W1 indicates the width direction of the long body I (201A) and the long body II (202A), and the arrow L1 indicates the longitudinal direction of the long body I (201) and the long body II (202A). To do.

  A pair of second cuts (425a) is formed from one end (202A ′) in the width direction of the long body II (202A) toward the center. On the other hand, a pair of first cuts (415a) is formed from one end (201A ′) in the width direction of the long body I (201A) toward the center. From the viewpoint of ease of manufacture, the longitudinal directions of the pair of first cuts (415a) and the pair of second cuts (425a) are, for example, the long body II (202A) and the long body I (201A), respectively. Parallel to the width direction.

  The length of the second cut (425a) is shorter than that of the first cut (415a). In the manufacturing method of the present embodiment, the length of the second cut (425a) is, for example, X2, and the length of the first cut (415a) is, for example, X1. X2 is equal to the vertical length of the extended portion (4012a) (see FIG. 1 and the like) of the soft medical container (1), and X1 is the vertical length of the extended portion (4011a) (see FIG. 1 and the like). It is equal to the sum of the length X2 and the vertical length of the remainder (403a) of the opening / closing operation unit (see FIG. 1 and the like).

  When one surface (the long body I (201A) and the long body II (202A) of the long body II (202A) is overlaid on the long body I (201A), the long body I (A surface opposite to the surface facing (201A)) is attached with a long sheet (23A) of a zip tape including a belt-like sheet (231a) and a concave portion or a convex portion arranged on the belt-like sheet by thermal bonding. It is attached. However, when the long body II (202A) itself is a long body of the strip-like sheet (231a) constituting the zip tape, the long body (23A) of the zip tape is thermally bonded to the long body II (202A). This is preferable because the step of performing is unnecessary. The thermal bonding of the long body (23A) of the zip tape may be performed before or after the formation of the second cut (425a).

  Next, the long body II (202A) and the long body I (201A) are overlapped so that the concave or convex portion of the long body 23A of the zip tape does not face the long body I (201A). When the long body II (202A) and the long body I (201A) are overlapped, the second cut (425a) and the first cut (415a) overlap. For example, the length of the second cut (425a) An end (426a) (upper end) close to one end (202A ') in the width direction of the scale II (202A) and one end (201A') in the width direction of the long body I (201A) of the first cut (415a) The long body II (202A) and the long body I (201A) are overlapped so that the end 416a (upper end) close to is aligned. In FIG. 7B, the long body I (201A) is overlaid on the long body II (202A).

  Next, as shown in FIG. 7B, among the laminated body of the long body II (202A) and the long body I (201A), the long body I (201A) of both ends in the longitudinal direction of the first cut (415a). ) The long body II (202A) and the long body I (201A) are joined by heat sealing below or on the end (417a) far from the one end (201A ′) in the width direction. Then, a dual structure lower heat seal region (203a) is formed. Moreover, the area | region used as the opening-and-closing operation part upper end heat seal area | region (4013a) of a laminated body is joined by heat sealing. There is no particular limitation on the order of forming the double structure lower heat seal region (203a) and the opening / closing operation unit upper end heat seal region (4013a), but at the same time as the formation of the double structure lower heat seal region (203a), the upper end of the opening / closing operation unit It is preferable to form the heat seal region (4013a) because the process is simplified. In addition, it is a part arrange | positioned above the opening / closing operation part upper end heat seal area | region (4013a) (area close | similar to the width direction one end (201A ') of the elongate body I (201A)), Comprising: Heat seal is required It is preferable that the part, for example, the part that becomes the hanging part (26a), is also heat-sealed simultaneously with the heat sealing in the area that becomes the opening / closing operation part upper end heat sealing area (4013a) in order to simplify the process.

  Next, as shown in FIG. 7C, in the region that becomes the top sheet heat seal region (204a) (see FIG. 1) of the laminate, the long body II (202A) and the long body I are sealed by heat sealing. (201A) is preferably joined. It is not always necessary to form the top sheet heat seal region (204a). However, if the inner sheet (202a) and the outer sheet (201a) are thermally bonded to the upper part of the outer peripheral edge of the top sheet (2a), Since the appearance of a soft container improves, it is preferable. At the same time, it is preferable to join the long body II (202A) and the long body I (201A) in the region to be the suspended portion (26a) by heat sealing. In the manufacturing method of Embodiment 1, the long sheet A (2A) of the topsheet is thus formed.

  In addition, in the manufacturing method of this embodiment, although heat sealing performed for formation of the elongate body A (2A) of a surface sheet (2a) is performed in two steps (refer FIG. 7B and FIG. 7C), From the viewpoint of simplifying the process, it may be performed in one step. More specifically, the double-structure lower heat seal area (203a), the opening / closing operation section upper end heat seal area (4013a), the topsheet upper heat seal area (204a), and the hanging part (26a) if necessary. Some thermal bonding may be performed simultaneously using a single heater head.

[Formation of long sheet B (2B) of back sheet]
On the other hand, in the first step, as shown in FIG. 7D, the long sheet IV (202B) of the inner sheet (202b) and the length of the outer sheet (201b) are formed to form the long sheet of the back sheet. A scale III (201B) is prepared. The arrow W2 indicates the width direction of the long body III (201B) and the long body IV (202B), and the arrow L2 indicates the longitudinal direction of the long body III (201B) and the long body IV (202B). To do.

  A pair of fourth cuts (425b) is formed from one end (202B ′) in the width direction of the long body IV (202B) toward the center. On the other hand, a pair of third cuts (415b) is formed from one end (201B ′) in the width direction of the long body III (201B) toward the center. The longitudinal direction of the pair of third cuts (415b) and the pair of fourth cuts (425b) is, for example, in the width direction of the long body III (201B) and the long body IV (202B) from the viewpoint of easy manufacture. And parallel.

  The length of the fourth cut (425b) is shorter than that of the third cut (415b). In the manufacturing method of the present embodiment, the length of the fourth cut (425b) is, for example, X2, and the length of the third cut (415b) is, for example, X1. X2 is equal to the vertical length of the extended portion (4012b) (see FIGS. 1 and 2) of the soft medical container, and X1 is the vertical length of the extended portion (4011b) and the remainder of the opening / closing operation portion. (403b) equal to the sum of the vertical lengths (see FIGS. 1 and 2).

  When one surface (the long body III (201B) and the long body IV (202B) of the long body IV (202B) before being overlaid on the long body III (201B) is overlapped, the long body III On the surface opposite to the surface facing (201A), a long body (23B) of a zip tape including a belt-like sheet (231b) and a concave portion or a convex portion arranged on the belt-like sheet is attached by thermal bonding. However, if the inner sheet (202b) itself is a belt-shaped sheet that constitutes a zip tape, the step of thermally bonding the long body (23B) of the zip tape to the long body IV (202B) becomes unnecessary. ,preferable. The thermal bonding of the long body (23B) of the zip tape may be performed before or after the formation of the fourth cut (425b).

  Next, the long body IV (202B) and the long body III (201B) are overlapped so that the concave or convex portion of the long body (23B) of the zip tape does not face the long body III (201B). When the long body IV (202B) and the long body III (201B) are overlapped, the fourth cut (425b) and the third cut (415b) overlap, for example, the length of the fourth cut (425b). An end (426b) (upper end) close to one end (202B ') in the width direction of the scale IV (202B) and one end (201B' in the width direction of the long body III (201B) of the third cut (415b) The long body IV (202B) and the long body III (201B) are overlapped so that the end (416b) (upper end) close to () is aligned. In FIG. 7E, the long body IV (202B) is overlaid on the long body III (201B).

  Next, as shown in FIG. 7E, in the laminate of the long body IV (202B) and the long body III (201B), the long body III (201B) out of the longitudinal ends of the third cut (415b). ) Of the long body IV (202B) and the long body III (201B) by heat sealing below or on the end (417b) far from the one end (201B ′) in the width direction. Join to form a dual structure lower heat seal area (203b). In addition, the region that becomes the upper and lower opening operation portion heat seal region (4013b) is also heat sealed. There is no particular limitation on the order of formation of the double structure lower heat seal region (203b) and the opening / closing operation unit upper end heat seal region (4013b), but simultaneously with the formation of the double structure lower heat seal region (203b), the upper end of the opening / closing operation unit If the heat seal region (4013b) is also formed, it is preferable if the process is simplified. It should be noted that the portion that is disposed above the opening / closing operation unit upper end heat seal region (4013b) (region closer to one side in the width direction of the elongated body) and that requires heat sealing (one of the hanging portions 26b). Part) is preferably heat-sealed at the same time as the heat sealing in the area to be the opening / closing operation part upper end heat sealing area (4013b) for simplification of the process.

  Next, as shown in FIG. 7F, it is preferable that the back sheet upper heat seal region (204b) (see FIG. 2) is formed by heat sealing. The formation of the back sheet upper heat seal region (204b) is not essential, but it is preferable that the inner sheet and the outer sheet are welded at the upper part of the outer peripheral edge of the top sheet because the appearance of the soft medical container is improved. At the same time, it is preferable that the inner sheet and the outer sheet in the region to be the suspended portion (26b) are also thermally bonded to each other by heat sealing. In the manufacturing method of the first embodiment, the long sheet B (2B) of the topsheet is thus formed.

  In addition, in the manufacturing method of this embodiment, although the heat sealing performed for formation of the elongate body of a surface sheet is performed in two steps (refer FIG. 7E and FIG. 7F), from a viewpoint of simplification of a process. It may be performed in one step. More specifically, the formation of the double structure lower heat seal region (203b), the opening / closing operation unit upper end heat seal region (4013b), the back sheet upper heat seal region (204b), and the hanging portion if necessary, It may be performed simultaneously using a single heater head.

(Second step)
Next, as shown in FIG. 7G, the long sheet A (2A) (see FIG. 7C) of the top sheet and the long body B (2B) (see FIG. 7F) of the back sheet are long of each inner sheet. After the body (202A, 202B) is stacked so as to face each other, the outer peripheral side heat seal region (24a) (see FIG. 1 and the like) and the outer peripheral bottom heat seal region (24b) (FIG. 1) are obtained by heat sealing (thermal bonding). The outer peripheral heat seal region (24) is formed. Before forming the outer peripheral heat seal region (24), the discharge port 3 (see FIG. 1) is sandwiched between the long sheet A of the top sheet and the long body B of the back sheet to form the outer peripheral heat seal region (24). It fixes between the elongate body A of a surface sheet, and the elongate body B of a back surface sheet by the heat seal (thermal bonding) for doing.

(Third step)
Next, a region to be the medical soft container (1) is cut out from the laminate of the long sheet of the top sheet and the long sheet of the back sheet, and the hanging holes (27a, 27b) are formed in the hanging parts (26a, 26b). ) To obtain a soft medical container (1) (see FIG. 7H, FIG. 1 and FIG. 2, etc.).

  As described above, in the manufacturing method according to the first embodiment, a medical soft container can be manufactured in a single manufacturing line in which stacking, heat sealing, and cutting of substantially flat medical soft container components are performed. The manufacturing cost of the medical soft container can be reduced.

  In the soft medical container described with reference to FIGS. 1 to 7H, the inner sheet is shorter in the vertical direction than the outer sheet, but the reverse is also possible.

  In the manufacturing method of the present embodiment described with reference to FIGS. 7A to 7H, the lengths of the first notch (415a) and the third notch (415b) are, for example, X1, and the second notch (425a) and the fourth notch The length of the cut (425b) is, for example, X2. However, the lengths of the first cut (415a) and the third cut (415b) and the lengths of the second cut (425a) and the fourth cut (425b) are as shown in FIGS. 8A and 8B, respectively. X1 + α1 and X1 + α3, X2 + α2 and X2 + α4 may also be used.

(First step)
[Long body A (2A) of surface sheet]
In the first step, as shown in FIG. 12A, in order to form the long sheet A (2A) (see FIG. 12C) of the top sheet, the vertical length of the outer sheet (201a) (see FIG. 10) A long body V (501A) of a soft resin sheet having a width longer than the total length in the vertical direction of the inner sheet 202a is prepared. The arrow W3 indicates the width direction of the long body V (501A), and the arrow L3 indicates the longitudinal direction of the long body V (501A).

  Below the region of the long body V (501A) that is supposed to be the upper end (22a) of the opening, the long body (23A) of the zip tape on the back of the long body V (501A) Is thermally bonded by heat sealing. Further, for example, a pair of fifth cuts (515a) longer than the sum of X2 and X1 is formed from one end (501A ′) in the width direction of the long body V (501A) toward the center. The length of the pair of fifth cuts (515a) is equal to, for example, a value obtained by subtracting X2 from the sum of twice X3 and X1. The longitudinal direction of the fifth cut (515a) is, for example, parallel to the width direction of the long body (501A) from the viewpoint of easy manufacture.

  X2 (see FIG. 9 and the like) is equal to the vertical length of the extension part (4012a) of the medical soft container (10) and the upper part (402a) of the opening / closing operation part, and X1 (see FIG. 9 and the like) is The vertical length of the extension part (4011a) and the vertical length of the remaining part (403a) of the opening / closing operation part are equal to each other, and X3 is equal to the vertical length of the suspension part (26a).

  Next, one end 501A ′ in the width direction of the long body V (501A) is in the same direction as the longitudinal direction of the long body V (501A), passes over the fifth cut (515a), and cuts (515a). For example, a valley fold is performed along a fold line (Y1) perpendicular to. The long body (23A) of the zip tape is not disposed between the sheet disposed above and the sheet disposed below by valley-folding the long body V (501A).

  The folding line (Y1) is, for example, an end on the fifth notch (515a) that is far from one end (501A ′) in the width direction of the elongated body V (501A) among the longitudinal ends of the fifth notch (515a). The distance from (516a) passes through the point of X3 and is orthogonal to the fifth cut (515a). By doing so, it is easy to form the suspended portion (26a). Further, the bending of the long body V (501A) can be rephrased so that the long body (23A) of the zip tape is not sandwiched between the region serving as the outer sheet (201a) and the region serving as the inner sheet (202a). The region to be the outer sheet (201a) is made not to face the long body (23A) of the zip tape.

  Next, as shown in FIG. 12A and FIG. 12B, the one end (501A ′) side in the width direction of the long body V (501A) is valley-folded along the fold line Y1, thereby the long body V (501A). One end (517a) of the fifth slit (515a) (one end in the width direction of the elongated body V (501A) among the longitudinal ends of the fifth slit (515a)) (The end close to (501A ′)) or near one end (517a) of the fifth cut (515a), the double sheets are joined together to form a double structure lower heat seal region (203a). To do.

  Next, as shown in FIG. 12C, by heat sealing, an area (see FIG. 9 and the like) that becomes the opening / closing operation unit upper end heat sealing area (4013a), a top sheet upper heat seal area (204a) (see FIG. 9 and the like) and The region to be formed and the region to be the suspended portion (26a) are heat-sealed. Although there is no restriction | limiting in particular about the heat-sealing order of these area | regions, When these are heat-sealed simultaneously, it is preferable when a process is simplified. Moreover, although formation of a top sheet | seat top heat seal area | region (204a) is not essential, if the inner sheet | seat (202a) and the outer sheet | seat (201a) are heat-bonded in the upper edge of a surface sheet, a medical soft container (10). This is preferable because of the improved appearance.

[Long body B (2B) of back sheet]
On the other hand, in the first step, as shown in FIG. 12D, the length of the outer sheet (201b) in the vertical direction and the inner sheet are formed in order to form the long sheet B (2B) (see FIG. 12F) of the back sheet. A long body IV (501B) of a soft resin sheet having a width longer than the total length in the vertical direction of (202b) is prepared. The arrow W4 indicates the width direction of the long body IV (501B), and the arrow L4 indicates the longitudinal direction of the long body IV (501B).

  Below the region of the long body IV (501B) that is planned to be the upper end (22a) of the opening, the long body (23B) of the zip tape is placed on the surface of the long body IV (501B). Is thermally bonded by heat sealing. Further, for example, a pair of sixth cuts (515b) longer than the sum of X2 and X1 is formed from one end (501B ′) in the width direction of the long body IV (501B) toward the center. The length of the pair of sixth cuts (515b) is, for example, equal to a value obtained by subtracting X2 from the sum of X2 and X1. The longitudinal direction of the cut (515b) is, for example, parallel to the width direction of the long body IV (501B) from the viewpoint of ease of manufacture.

  X2 (see FIG. 10 and the like) is equal to the vertical length of the extension part (4012b) of the medical soft container (10) and the upper part (402b) of the opening / closing operation part, and X1 (see FIG. 10 and the like) is The vertical length of the extension part (4011b) and the vertical length of the remaining part (403b) of the opening / closing operation part are equal to each other, and X3 is equal to the vertical length of the suspension part (26b) (FIG. 10). reference).

  Next, one end (501B ′) in the width direction of the long body IV (501B) is in the same direction as the longitudinal direction of the long body IV (501B), passes through the sixth cut (515b), and the sixth For example, a mountain fold is performed along a fold line Y2 perpendicular to the notch (515b). The long body (23B) of the zip tape is not disposed between the sheet disposed above and the sheet disposed below by folding the long body (501B). The fold line Y2 is, for example, a distance from an end 516b far from one end 501B ′ in the width direction of the long body IV (501B) out of both ends in the longitudinal direction of the sixth notch (515b) on the sixth notch (515b). Passes through the point X3 and is orthogonal to the sixth notch (515b). By doing so, it is easy to form the suspended portion (26b). In other words, the long body IV (501B) is folded so that the long body 23B of the zip tape is not sandwiched between the region serving as the outer sheet (201b) and the region serving as the inner sheet (202b). The region to be the sheet (201b) is made not to face the long zip tape (23B).

  Next, as shown in FIGS. 12D and 12E, the width direction one end 501B ′ side of the long body VI (501B) is mountain-folded along the fold line Y2, so that the width of the long body VI (501B) is obtained. One end (517b) of the sixth notch (515b) (one end (501B ′) in the width direction of the long body VI (501B) of both ends in the longitudinal direction of the notch (515b)) The double sheets are joined to each other near the one end (517b) below the end close to the top or near the one end (517b) on the sixth cut (515b) to form a double structure lower heat seal region (203b).

  Next, as shown in FIG. 12F, by heat sealing, a region (see FIG. 10 and the like) that becomes the opening / closing operation unit upper end heat sealing region (4013b), a back sheet upper heat seal region (204b) (see FIG. 10 and the like), and The region to be formed and the region to be the suspended portion (26b) are heat-sealed. Although there is no restriction | limiting in particular about the heat-sealing order of these area | regions, When these are heat-sealed simultaneously, it is preferable when a process is simplified. In addition, the formation of the back sheet upper heat seal region (204b) is not essential, but when the inner sheet (202b) and the outer sheet (201b) are thermally bonded at the upper edge of the top sheet, the soft medical container (10) This is preferable because of the improved appearance.

(Second step)
Next, the long body A (2A) of the top sheet and the long body B (2B) of the back sheet are folded to the one end (501A ′) side in the width direction of the folded long body V (501A). The long body V (501A) and the long body VI (501B) are overlapped so that the width direction one end (501B ′) side of the long body VI (501B) thus formed does not face each other. After that, as shown in FIG. 12G, the outer peripheral side heat seal region (24a) (see FIG. 9 etc.) and the outer peripheral bottom heat seal region (24b) (see FIG. 9 etc.) by heat sealing (thermal bonding) An outer peripheral heat seal region (24) is formed.
