     PREFERRED MODE FOR CARRYING OUT THE INVENTION 
     Hereinafter, preferred embodiments of a medical container of the present invention will be described with reference to the drawings. First, a configuration of the medical container of the first embodiment will be described with reference to  FIG. 1  to  FIG. 3 . The medical container is used to accommodate an instrument, a pharmaceutical preparation, or the like used for medical treatment as an accommodated object, and to protect the accommodated object from contamination to maintain hygiene. A medical container  1  of the first embodiment accommodates an accommodating container  60  that accommodates, as an accommodated object, cells used for regenerative medicine, or the like. 
     As illustrated in  FIG. 1  to  FIG. 3 , the medical container  1  is formed in a bag shape by joining together rims of a set (two) of sheet-shaped members  50  and  50  disposed (see  FIG. 3 ) facing each other by heat sealing or ultrasonic joining except an accommodating opening  70  (upper side portion in  FIG. 1 ) for accommodating an accommodated object. The sheet-shaped members  50  are made of flexible thermoplastic resin. Examples of the material constituting the sheet-shaped members include EVA resin (ethylene-vinyl acetate copolymer resin), polyolefins such as polyethylene and polypropylene, and vinyl chloride. In the present embodiment, the sheet-shaped members  50  are made of EVA resin. The sheet-shaped members  50  are made of EVA resin, so that even when the medical container  1  is cryopreserved, the flexibility can be maintained, and the medical container  1  can be prevented from being damaged at a low temperature. 
     As illustrated in  FIG. 1  to  FIG. 3 , the medical container  1  includes an accommodation part  10 , a pair of the extending parts  20 , a pair of partition joining parts  30 , regulating joining parts  40 , and the accommodating opening  70 . 
     As illustrated in  FIG. 1  and  FIG. 2 , the accommodation part  10  is formed in a rectangular shape in which the length in the width direction WD is shorter than the length in the height direction HD, and is disposed at a central part in the width direction WD of the medical container  1 . The accommodation part  10  accommodates, as an accommodated object, an instrument, a pharmaceutical preparation, or the like used for medical treatment in a sterile state. In the present embodiment, as illustrated in  FIG. 2 , the accommodation part  10  accommodates a cylindrical accommodating container  60  that accommodates cells used for regenerative medicine. The accommodating container  60  includes a cylindrical main body  61  having an open one end side and a cap  62  detachably attached to the main body  61 , and the cap  62  is accommodated in the accommodation part  10  so as to be located on the upper end side of the medical container  1  which is one end side in the height direction HD of the medical container  1 . In the present embodiment, as illustrated in  FIG. 2 , the length W 1  in the width direction WD of the accommodation part  10  is configured to be larger than the width W 2  in the accommodating container  60 . 
     In this specification, the direction in which the accommodation part  10  and a pair of the extending parts  20  are lined up (the horizontal direction in  FIG. 1 ) is defined as the width direction WD of the medical container  1 , the direction that intersects the width direction WD and is along the plane direction of the sheet-shaped members  50  (vertical direction in  FIG. 1 ) is defined as the height direction HD, and the overlapping direction of a set of the sheet-shaped members  50  and  50  (vertical direction in  FIG. 3 ) is defined as the thickness direction TD. 
     The pair of extending parts  20  extends outward in the width direction WD from the accommodation part  10 . In each of the extending parts  20 , a set of the sheet-shaped members  50  is joined together at a lateral side along the height direction HD, and a base side which is a side on the other end side in the height direction HD, and a set of the sheet-shaped members  50  is not joined together at other portions. Each extending part  20  is disposed on the one end side in the height direction HD of the accommodation part  10 . As illustrated in  FIG. 1 , the length H 1  in the height direction HD of the extending part  20  is configured to be shorter than the length H 2  of the accommodation part  10  in the height direction HD. Further, the base side of the extending part  20  is inclined on one end side in the height direction HD from an end portion in the width direction WD toward the accommodation part  10  toward. That is, the base side of the extending part  20  is formed in a straight line that is inclined upward from the end portion in the width direction WD toward the accommodation part  10 . 
     The angle θ 1  formed by the base side of the extending part  20  and the lateral side along the height direction HD of the accommodation part  10  is preferably 0° to 90°. 
     A pair of the partition joining parts  30  is formed by joining together a set of the sheet-shaped members  50 , and extends from the other end side to the one end side in the height direction HD of the medical container  1 , and partition the accommodation part  10  and the extending parts  20  at boundary portions between the accommodation part  10  and a pair of the extending parts  20 . In the present embodiment, the partition joining parts  30  are provided such that the lateral sides along the height direction HD of the accommodation part  10  extends to one end side (upper end side). That is, the partition joining parts  30  are disposed on extension lines of the sides along the height direction HD of the accommodation part  10 . The partition joining parts  30  do not completely partition the accommodation part  10  and a pair of the extending parts  20 , but partially partition the accommodation part  10  and a pair of the extending parts  20 . That is, the accommodation part  10  and the extending parts  20  have communicating portions on the one end side (upper end side) in the height direction HD. 
     A position  30   a  of an end portion on the one end side (upper end side) in the height direction HD of each partition joining part  30  is located on the other end side (lower end side) with respect to one end portion (upper end portion)  60   a  in the height direction HD of the accommodating container  60  in a state in which the accommodating container  60  is accommodated in the accommodation part  10  (see  FIG. 2 ). Further, the length H 0  from the position  30   a  of the end portion on the one end side (upper end side) in the height direction HD of each partition joining part  30  to the opening for extraction of the medical container  1  is made to be an appropriate dimension (length), so that the sheet-shaped members  50 , which will be described later, can be easily inverted. 
     The regulating joining parts  40  are formed by joining together a set of the sheet-shaped members  50 , and regulate the position of the accommodating container  60  accommodated in the accommodation part  10 . In the present embodiment, the regulating joining parts  40  are formed by two joining parts linearly extending in the height direction HD at a predetermined interval in the width direction WD at the central part in the width direction WD of the accommodation part  10 . Further, the regulating joining parts  40  are each provided so as to extend from the base side which is the side on the other end side in the height direction HD of the accommodation part  10  by a predetermined height. The length W 3  in the width direction WD between the two joining parts constituting the regulating joining parts  40  is set to be slightly larger than the size (width) W 2  of the accommodating container  60 . 
     The accommodating opening  70  is formed without joining together a part of the rims of a set of the sheet-shaped members  50 . In the first embodiment, the accommodating opening  70  is provided over the entire length of the side on the one end side (upper end side) in the height direction. 
     The medical container  1  of the first embodiment described above is used as follows. When the accommodating container  60  is accommodated in the medical container  1 , the accommodating container  60  accommodating cells is accommodated, from the accommodating opening  70 , in the medical container  1  in which all sides except an upper side, which is a side on the one end side in the height direction HD and is provided with the accommodating opening  70 , are joined together. Herein, the accommodating container  60  is inserted between the two joining parts constituting the regulating joining parts  40  such that the cap  62  is located on the upper end side, and is accommodated in a state of being positioned in the accommodation part  10 . Thereafter, the upper side of the medical container  1  is joined together, and the accommodating container  60  is accommodated in the medical container  1  in a sealed state. In this state, the upper end portion  60   a  of the accommodating container  60  is located on the upper end side with respect to the upper end portions  30   a  of the partition joining parts  30  (see  FIG. 2 ). 
     The cells accommodated in the accommodating container  60  are accommodated in the medical container  1  and cryopreserved in a sealed state until the cells are used. Herein, the medical container  1  is made of EVA resin, so that even when the medical container  1  is cryopreserved, flexibility can be maintained, and the medical container  1  can be prevented from being damaged at a low temperature. 
     When the cells accommodated in the accommodating container  60  are used, the cells are transported to an operating room or the like in which an unclean field and a clean field are separated, in a state in which the cells are accommodated in the medical container  1 . Then, the medical container  1  is opened by a person in charge of the unclean field, and the accommodating container  60  is extracted from the medical container  1  by a person in charge of the clean field. 
     A procedure for extracting the accommodating container  60  from the medical container  1  will be described with reference to  FIG. 4  to  FIG. 6 . First, as illustrated in  FIG. 4 , the person in charge of the unclean field cuts the upper side of the medical container  1  with scissors or the like. Consequently, an opening for extraction is provided on the upper side of the medical container  1 . Herein, the cutting position on the upper side of the medical container  1  is preferably such a position that an angle θ 0  (see  FIG. 4 ) formed by the upper end portion  30   a  of each partition joining part  30  and the end portion of the opening for extraction is 90° to 160° after cutting, and more preferably such a position that the angle θ 0  is 100° to 140°. 
     Then, as illustrated in  FIG. 5 , a pair of the extending parts  20  are held by the person in charge of the unclean field. Herein, in a pair of the extending parts  20 , a set of the sheet-shaped members  50  is not joined together except for the rim parts (lateral sides and bottom sides), and therefore the person in charge of the unclean field inserts, for example, his/her thumbs into a pair of the extending parts  20  from the opening, and sandwiches a sheet of the sheet-shaped member  50  between the inserted thumbs and his/her forefingers, so that it is possible to hold the extending parts  20 . Further, the partition joining parts  30  are disposed between the extending parts  20  and the accommodation part  10 , and therefore when the extending parts  20  are held, it is possible to prevent the fingers of the person in charge of the unclean field from entering the accommodation part  10  side. 
     Then, as illustrated in  FIG. 6 , a set of the sheet-shaped members  50  and  50  is inverted at the opening in a state in which a pair of the extending parts  20  is held by the person in charge of the unclean field. More specifically, in a pair of the extending parts  20 , the front and back of the sheet-shaped member  50  sandwiched between the thumbs inserted between a set of the sheet-shaped members  50  and  50  and the forefingers disposed outside the sheet-shaped members  50  are inverted, so that the front and back of the sheet-shaped members  50  in the vicinity of the opening are inverted. Consequently, in the vicinity of the opening, inner surfaces of the clean sheet-shaped members  50  that are not exposed to the outside world are exposed to the outside. In this state, the accommodating container  60  is hygienically extracted by the person in charge of the clean field. 
     Herein, in the present embodiment, the medical container  1  is configured to include the accommodation part  10  and a pair of the extending parts  20  extending outward in the width direction WD from the accommodation part  10 . Consequently, it is possible to secure the long length in the width direction WD of the opening. Accordingly, a set of the sheet-shaped members  50  and  50  can be easily inverted at the opening by holding a pair of the extending parts  20  with both hands, and therefore the accommodating container  60  accommodated in the accommodation part  10  can be extracted in a state in which the inner surfaces of the uncontaminated sheet-shaped members  50  are exposed. 
     The length H 1  in the height direction HD of each extending part  20  is made shorter than the length H 2  in the height direction HD of the accommodation part  10 . Further, the base sides of the extending parts  20  are inclined upward from the end portion in the width direction WD toward the accommodation part  10 . Consequently, when the sheet-shaped members  50  are inverted at the opening, the extending parts  20  can be prevented from interfering with the accommodation part  10 , and therefore the sheet-shaped members can be inverted smoothly. 
     when a set of the sheet-shaped members  50  and  50  is inverted at the opening, the sheet-shaped members  50  and  50  can be inverted with the upper end portions  30   a  of the partition joining parts  30  as bending starting points of the sheet-shaped members  50 , and therefore a set of the sheet-shaped members  50  and  50  can be inverted more stably. That is, when the sheet-shaped members  50  are to be inverted at the opening, it is possible to prevent a set of the sheet-shaped members  50  and  50  from being bent together on one side in the thickness direction TD and closing the opening. The positions  30   a  of the upper end portions of the partition joining parts  30  are located on the lower end side with respect to the upper end portion  60   a  of the accommodating container  60  in the state in which the accommodating container  60  is accommodated in the accommodation part  10 . Consequently, when the sheet-shaped members  50  are inverted at the opening, an end portion of the accommodating container  60  can be protruded from the opening. Accordingly, the accommodating container  60  can be extracted more easily and hygienically. 
     According to the medical container  1  of the first embodiment described above, the following effects are obtained. 
     (1) The medical container  1  is provided by joining together the rims of a set of the sheet-shaped members  50  and  50 , and configured to include the accommodation part  10 , and a pair of the extending parts  20  that is disposed on the one end side in the height direction HD of the accommodation part  10  and extends outward in the width direction WD from the accommodation part  10 . Consequently, when the one end side in the height direction HD of the accommodating container  60  is opened with scissors or the like, and the accommodating container  60  accommodated in the medical container  1  is extracted, it is possible to secure the longer length in the width direction of the opening provided by opening with the scissors or the like. Accordingly, while a pair of the extending parts  20  are held with both hands, a set of the sheet-shaped members  50  and  50  can be easily inverted at the opening, and therefore the accommodating container  60  accommodated in the accommodation part  10  can be extracted in the state in which the inner surfaces of the uncontaminated sheet-shaped members  50  are exposed. As a result, the accommodating container  60  can be easily extracted without being contaminated. Further, in a pair of the extending parts  20 , a set of the sheet-shaped members  50  and  50  is inverted by inserting fingers between a set of the sheet-shaped members  50  and  50 , so that the fingers are not in contact with the accommodation part  10 , and therefore the accommodating container  60  can be more hygienically extracted. 
     (2) The medical container  1  is configured to include the partition joining parts  30  that extend from the other end side to the one end side in the height direction HD and partition the accommodation part  10  and the extending parts  20 . Consequently, when a set of the sheet-shaped members  50  and  50  is inverted at the opening, the end portions of the partition joining parts  30  can be inverted as the bending starting points of the sheet-shaped members  50 , and therefore a set of the sheet-shaped members  50  and  50  can be inverted more stably. That is, when the sheet-shaped members  50  are to be inverted at the opening, a set of the sheet-shaped members  50  and  50  is prevented from being bent together on one side in the thickness direction TD and closing the opening. Further, when fingers are inserted between a set of the sheet-shaped members  50  and  50  in a pair of the extending parts  20  to invert a set of the sheet-shaped members  50  and  50 , the inserted fingers are prevented from moving toward the accommodation part  10 , and therefore the accommodating container  60  can be more hygienically extracted. 
     (3) The position  30   a  of the end portion (upper end portion) on the one end side in the height direction HD of each partition joining part  30  is located on the other end side (lower side) with respect to the one end portion (upper end portion)  60   a  in the height direction HD of the accommodating container  60  in the state in which the accommodating container  60  is accommodated in the accommodation part  10 . Consequently, when the sheet-shaped members  50  are inverted at the opening, the end portion of the accommodating container  60  can be protruded from the opening. Accordingly, the accommodating container  60  can be extracted more easily and hygienically. 
     (4) The medical container  1  is configured to include the regulating joining parts  40  that regulate the position of the accommodating container  60  accommodated in the accommodation part  10 . Consequently, even when the accommodation part  10  is made wider than the width of an accommodated object, the accommodating container  60  accommodated in the accommodation part  10  can be positioned. Therefore, when the accommodating container  60  is extracted, a tip of the accommodating container  60  is suitably protruded from the opening. Accordingly, it is possible to further improve the extractability of the accommodating container  60 . 
     (5) The length H 1  in the height direction HD of each extending part  20  is configured to be shorter than the length H 2  in the height direction HD of the accommodation part  10 . Consequently, the position on the other end side (lower end side) in the height direction HD of each extending part  20  can be made higher than the position on the other end side (lower end side) in the height direction HD of the accommodation part  10 . Accordingly, when the sheet-shaped members  50  are inverted at the opening, the extending parts  20  can be less likely to interfere with the accommodation part  10 , and therefore the sheet-shaped members  50  are inverted smoothly. 
     (6) The side on the other end side (lower end side) in the height direction HD of each extending part  20  is inclined on the one end side (upper end side) from the end portion in the width direction ND toward the accommodation part  10 . Consequently, when the sheet-shaped members  50  are inverted at the opening, the extending parts  20  can be further less likely to interfere with the accommodation part  10 , and therefore the sheet-shaped members  50  are inverted smoothly. The areas of the extending parts  20  can be sufficiently secured particularly on the outside in the width direction WD, and therefore when the sheet-shaped members  50  are inverted, the extending parts  20  can be firmly held by the thumbs and the forefingers. Accordingly, it is possible to improve operability when the sheet-shaped members  50  are inverted. 
     Now, a medical container  1 A according to a second embodiment of the present invention will be described with reference to  FIG. 7 . In the description of the second embodiment, the same components are denoted by the same reference numerals, and the description thereof will be omitted or simplified. The medical container  1 A of the second embodiment is different from the first embodiment mainly in that the medical container  1 A does not include any partition joining part and any regulating joining part. In the medical container  1 A of the second embodiment, as illustrated in  FIG. 7 , the length in the width direction WD of an accommodation part  10 A is configured to be slightly larger than the width of an accommodating container  60  as an accommodated object. Consequently, the accommodating container  60  is accommodated in a state of being positioned in the accommodation part  10 A. Further, in the second embodiment, when the medical container  1 A is opened and the sheet-shaped members  50  are inverted at an opening, joining parts of boundary portions between the accommodation part  10 A and extending parts  20  serve as bending starting points, and the sheet-shaped members  50  are inverted. According to the medical container  1 A of the second embodiment, the above effects (1), (5) and (6) are obtained. 
     Now, a medical container  1 B according to a third embodiment of the present invention will be described with reference to  FIG. 8  to  FIG. 10 . 
     As illustrated in  FIG. 8  to  FIG. 10 , the medical container  1 B is formed in a bag shape by joining together rims of a set (two) of sheet-shaped members  50  and  50  (see  FIG. 10 ) disposed facing each other by heat sealing or ultrasonic joining except an accommodating opening  70  (upper side portion in  FIG. 8 ) for accommodating an accommodated object. 
     As illustrated in  FIG. 8  to  FIG. 10 , the medical container  1 B includes an accommodation part  10 B, an inclined part  20 B, a rectangular part  30 B, and the accommodating opening  70 . 
     As illustrated in  FIG. 8  and  FIG. 9 , the accommodation part  10 B is formed in a rectangular shape in plan view in which the length d in the width direction WD (hereinafter, also referred to as the width d of the accommodation part  10 B) is shorter than the length in the height direction HD, and is disposed at the central part in the width direction WD of the medical container  1 B. The accommodation part  10 B accommodates, as an accommodated object, an instrument, a pharmaceutical preparation, or the like used for medical treatment in a sterile state. In the present embodiment, as illustrated in  FIG. 9 , the accommodation part  10 B accommodates a cylindrical accommodating container  60  that accommodates cells used for regenerative medicine. The accommodating container  60  includes a cylindrical main body  61  having an open one end side and a cap  62  detachably attached to the main body  61 , and the cap  62  is accommodated in the accommodation part  10 B so as to be located on the upper end side of a medical container  1  which is one end side in the height direction HD of the medical container  1 . The width d of the accommodation part  10 B may be configured to have a length into which the accommodating container  60  can be inserted. In the present embodiment, as illustrated in  FIG. 9 , the width d of the accommodation part  10 B is set to be about twice the width W of the cap  62  of the accommodating container  60 . Consequently, when the accommodating container  60  is inserted into the accommodation part  10 B, the accommodating container  60  can be easily inserted. Herein, the accommodating container  60  is preferably set the length in the height direction HD of the accommodation part  10 B so as to protrude from an upper end portion of the accommodation part  10 B by about 10 mm to 15 mm, in a state in which the accommodating container  60  is accommodated in the accommodation part  10 B. Consequently, the accommodating container  60  can be easily extracted from the accommodation part  10 B. 
     In the present embodiment, the left-right direction in  FIG. 8  is defined as the width direction WD of the medical container  1 B, the direction that intersects the width direction WD and is along the plane direction of the sheet-shaped members  50  (vertical direction in  FIG. 8 ) is defined as the height direction HD, and the overlapping direction of a set of the sheet-shaped members  50  and  50  (vertical direction in  FIG. 10 ) is defined as the thickness direction TD. 
     The inclined part  20 B is disposed on the one end side in the height direction HD of the accommodation part  10 B (the upper end side of the accommodation part  10 B). The inclined part  20 B communicates with the accommodation part  10 B, and is formed in a shape in which the length in the width direction WD becomes longer (wider) toward the one end side (upper side) in the height direction HD. The inclined part  20 B has a pair of lateral sides that is inclined with respect to the height direction HD and extends on both sides in the width direction WD. In the inclined part  20 B, a set of the sheet-shaped members  50  is joined together at a pair of the lateral sides, and a set of the sheet-shaped members  50  is not joined together at other portions. The length in the width direction WD of the inclined part  20 B is configured to gradually increase from the accommodation part  10 B toward the rectangular part  30 B. The minimum width of the inclined part  20 B is the same width as the width d of the upper end portion of the accommodation part  10 B, and the maximum width is the same width as the width c of the rectangular part  30 B. In the present embodiment, a pair of the lateral sides of the inclined part  20 B is inclined at the same angle with respect to the height direction HD, and extends. 
     The rectangular part  30 B is disposed on one end side (upper end side of the inclined part  20 B) in the height direction HD of the inclined part  20 B. In the rectangular part  30 B, a set of the sheet-shaped members  50  is joined together on the lateral sides along the height direction HD, and a set of the sheet-shaped members  50  is not joined together at other portions. The length c in the width direction WD of the rectangular part  30 B (hereinafter, also referred to as the width c of the rectangular part  30 B) is configured to be larger than the width d of the upper end portion of the accommodation part  10 B. Further, as will be described in detail later, when the accommodating container  60  is extracted, the medical container  1 B is cut along the width direction WD in the vicinity of a boundary part BD with the inclined part  20 B in the rectangular part  30 B. 
     The accommodating opening  70  is provided without partially joining together rims of a set of sheet-shaped members  50 . In the present embodiment, the accommodating opening  70  is provided over the entire length of the side on the one end side (upper end side) in the height direction, that is, the side on the upper end side of the rectangular part  30 B. 
     The medical container  1 B of the present embodiment described above is used as follows. 
     When the accommodating container  60  is accommodated in the medical container  1 B, the accommodating container  60  accommodating cells is accommodated, from the accommodating opening  70 , in the medical container  1 B in which all sides except an upper side, which is the side on the one end side in the height direction HD and is provided with the accommodating opening  70 , are joined together. Herein, the accommodating container  60  accommodated in the accommodation part  10 B such that the cap  62  is located on the upper end side. Thereafter, the upper side of the medical container  1 B is joined together, and the accommodating container  60  is accommodated in the medical container  1 B in a sealed state. In this state, an upper end portion  60   a  of the accommodating container  60  is located on the lower end side with respect to the boundary part BD between the rectangular part  30 B and the inclined part  20 B, that is, inside the inclined part  20 B (see  FIG. 9 ). 
     The cells accommodated in the accommodating container  60  are accommodated in the medical container  1 B and cryopreserved in the sealed state until the cells are used. 
     When the cells accommodated in the accommodating container  60  are used, the cells are transported to an operating room or the like in which an unclean field and a clean field are separated in a state of being accommodated in the medical container  1 B. Then, the medical container  1 B is opened by a person in charge of the unclean field, and the accommodating container  60  is extracted from the medical container  1 B by a person in charge of the clean field. 
     In the medical container  1 B of the present embodiment, the shape of the inclined part  20 B is properly set, so that it is possible to easily invert the inclined part  20 B after cutting. 
     A procedure for extracting the accommodating container  60  from the medical container  1 B will be described with reference to  FIG. 11  to  FIG. 13 . First, as illustrated in  FIG. 11 , the person in charge of the unclean field cuts a predetermined cutting position of the medical container  1 B with scissors or the like. Consequently, an opening for extraction is provided on the upper side of the medical container  1 B. Herein, the medical container  1 B is preferably cut in the vicinity of the boundary part BD with the inclined part  20 B in the rectangular part  30 B (see  FIG. 8  and  FIG. 9 ). In the present embodiment, the shape of the inclined part  20 B is set such that the distance b in the height direction HD between the upper end portion of the accommodation part  10 B and the boundary part BD is 20 mm or more and 40 mm or less. The distance b is set to 20 mm or more, so that it is possible to prevent scissors or the like from touching the upper end portion  60   a  of the accommodating container  60  when cutting the rectangular part  30 B in the vicinity of the boundary part BD. 
     Next, as illustrated in  FIG. 12 , the inclined part  20 B is held by the person in charge of the unclean field. Herein, in the inclined part  20 B, a set of the sheet-shaped members  50  is not joined together except for the rim parts (sides), and therefore the person in charge of the unclean field inserts, for example, his/her thumbs into the inclined part  20 B from the opening, and sandwiches the sheet-shaped members  50  between the inserted thumbs and his/her forefingers, so that it is possible to hold the inclined part  20 B Herein, a distance a in the width direction WD between an end portion of the upper end portion of the accommodation part  10 B and an end portion of the rectangular part  30 B is made to be 35 mm or more, so that the person in charge of the unclean field can insert his/her thumbs of his/her both hands into the inclined part  20 B without touching the accommodating container  60 . 
     Then, as illustrated in  FIG. 13 , a set of the sheet-shaped members  50  and  50  is inverted at the opening in a state in which the inclined part  20 B is held by the person in charge of the unclean field. More specifically, in the inclined part  20 B, the front and back of the sheet-shaped members  50  sandwiched between the thumbs inserted between a set of the sheet-shaped members  50  and  50  and the forefingers disposed outside the sheet-shaped members  50  are inverted, so that the front and back of the sheet-shaped members  50  in the vicinity of the opening are inverted. Consequently, in the vicinity of the opening, inner surfaces of the clean sheet-shaped members  50  that are not exposed to the outside world are exposed to the outside. In this state, the accommodating container  60  is hygienically extracted by the person in charge of the clean field. 
     Herein, the distance a between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B is made to be 70 mm or less, and the distance b between the upper end portion of the accommodation part  10 B and the boundary part BD (the upper end portion of the inclined part  20 B) is made to be 40 mm or less, so that a position in the height direction HD where the inclined part  20 B is inverted can be brought closer to the upper end portion of the accommodation part  10 B. Accordingly, the inverted position in the inclined part  20 B is lower than the upper end portion  60   a  of the accommodating container  60 , and therefore it is possible to increase an exposed portion of the upper end portion of the accommodating container  60  from the medical container  1 B, and the person in charge of the clean field can easily extract the accommodating container  60 . When the distance a exceeds 70 mm, finger grip portions of the inclined part  20 B and the sheet-shaped member  50  portions in a vicinity portion thereof can be easily inverted, but it becomes difficult to invert the opening side at the central portion in the width direction WD, which is a portion for extracting the accommodating container  60 . As a result, it becomes difficult to set the inverted position to an appropriate position. Further, when the distance b exceeds 40 mm, it becomes difficult to invert the inclined part  20 B, which is not preferable. That is, the distance a between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B is 70 mm or less, and the distance b between the upper end portion of the accommodation part  10 B and the boundary part BD (the upper end portion of the inclined part  20 B) is 40 mm or less, so that the accommodating container  60  can be easily inverted at the appropriate position, and it is possible to increase the exposed portion of the upper end portion of the accommodating container  60  from the medical container  1  in the inverted state, and therefore it is possible to easily extract the accommodating container  60 . 
     In the present embodiment, as described above, the cutting position for opening the medical container  1 B is set to the vicinity of the boundary part BD with the inclined part  20 B in the rectangular part  30 B, so that it is possible to easily invert the inclined part  20 B compared to a case where the rectangular part  30 B is cut above the vicinity of the boundary part BD. A mark for indicating the cutting position for opening may be given to the medical container  1 B. Examples of the mark for indicating the cutting position include a display attached to the sheet-shaped members  50  along the cutting position, a notch provided on the side portion of the rectangular part  30 B, or the like. 
     According to summarization of a result examined by the present inventor, it is found that when the distance a in the width direction WD between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B is 35 mm or more and 70 mm or less, and when the distance b in the height direction HD between the upper end portion of the accommodation part  10 B and the boundary part BD with the accommodation part  10 B (the upper end portion of the inclined part  20 B) is 20 mm or more and 40 mm or less, the inclined part  20 B is easily inverted after cutting the medical container  1 B at the boundary part BD. 
     In addition, the present inventor further examined the preferable shape of the inclined part  20 B for easily inverting the inclined part  20 B from various viewpoints. As a result, it is found that the length d (accommodation part  10 B) in the width direction WD of the accommodation part  10 B is not preferably more than the distance a in the width direction WD between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B, and the length c in the width direction WD of the rectangular part  30 B (width of the rectangular part  30 B) is preferably 200 mm or less, and the angle θ 2  on the acute angle side with respect to the width direction WD of the lateral side of the inclined part  20 B is 20° or more and 40° or less. 
     According to the medical container  1  of the embodiment described above, the following effects are obtained. 
     (7) The medical container  1 B is provided by joining together the rims of a set of sheet-shaped members  50  and  50 , and is configured to include the accommodation part  10 B, the inclined part  20 B disposed on the upper end side in the height direction HD of the accommodation part  10 B, and the rectangular part  30 B disposed on the upper end side in the height direction of this inclined part  20 B, and the inclined part  20 B is configured such that the width gradually decreases from the upper end side to the lower end side, the distance a in the width direction WD between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the upper end portion of the inclined part  20 B is set to 35 mm or more and 70 mm or less, and the distance b in the height direction HD between the upper end portion of the accommodation part  10 B and the boundary part BD is set to 20 mm or more and 40 mm or less. Consequently, when the one end side in the height direction HD of the medical container  1 B is opened with scissors or the like and the accommodating container  60  accommodated in the medical container  1 B is extracted, the medical container  1 B is cut in the vicinity of the boundary part BD between the rectangular part  30 B and the inclined part  20 B, so that a set of the sheet-shaped members  50  and  50  can be easily inverted by holding the inclined part  20 B with both hands. Accordingly, the accommodating container  60  accommodated in the accommodation part  10 B can be extracted in a state in which inner surfaces of the uncontaminated sheet-shaped members  50  are exposed. Accordingly, the inverted position in the inclined part  20 B can be set to the vicinity of the accommodation part  10 B, and therefore the accommodating container  60  can be easily extracted. Further, when cutting, it is possible to prevent scissors or the like from touching the upper end portion  60   a  of the accommodating container  60 . As a result, the accommodating container  60  can be easily extracted without being contaminated. Further, when fingers are inserted between a set of the sheet-shaped members  50  and  50  in the inclined part  20 B, and a set of the sheet-shaped members  50  and  50  is inverted, so that the inserted fingers are prevented from touching the accommodation part  10 B, and therefore the accommodating container  60  can be more hygienically extracted. 
     (8) The width d of the upper end portion of the accommodation part  10 B is set to at most the distance a between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B. Consequently, the force of the fingers when the fingers are put into the inclined part  20 B and the inclined part  20 B is inverted is easily transmitted to the inclined part  20 B, and therefore the inclined part  20 B can be inverted more easily. 
     (9) The width of the rectangular part  30 B is set to be 200 mm or less. Consequently, the inverted position in the inclined part  20 B can be set to the vicinity of the accommodation part  10 B, and therefore the accommodating container  60  can be easily extracted. 
     (10) The angle θ 2  on the acute angle side with respect to the width direction WD of the lateral side of the inclined part  20 B is set to be 20° or more and 40° or less. Consequently, a set of the sheet-shaped members  50  and  50  can be easily inverted by holding the inclined part  20 B with both hands. 
     EXAMPLES 
     Example 1 
     Next, as to the medical container  1 B of the present embodiment, medical containers obtained by variously changing the distance a between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the upper end portion of the inclined part  20 B, and the distance b between the upper end portion of the accommodation part  10 B and the boundary part BD (the upper end portion of the inclined part  20 B) were prepared as test specimens, and the ease of inversion was evaluated. The width d of the accommodation part  10 B was set to 27 mm. The results are illustrated in Table 1, and the relationship between the distance a and the distance b is illustrated in Table 2 by the angle  82  on the acute angle side with respect to the width direction WD of the lateral side of the inclined part  20 B. As the sheet-shaped member constituting the medical container  1 B used in the examples, a sheet having a thickness of 0.35 mm made of EVA resin was used. As to the ease of inversion in Table 1, while one that can be inverted without putting fingers all the way into the inclined part  20 B and does not have any feeling of resistance is defined as “very good” (indicated by bullseye symbol (⊙)), one that can be inverted without putting fingers all the way into the inclined part  20 B but has a feeling of resistance is defined as “good” (indicated by circle symbol (∘)), one that can be inverted by putting fingers all the way into the inclined part  20 B but has a feeling of resistance is defined as “fair” (indicated by triangle symbol  1  (Δ 1 )), one that can be inverted in the vicinity of a finger gripping point but cannot be smoothly inverted at a central part (opening) provided with the accommodation part accommodated in the accommodating container is defined as “poor” (indicated by triangle symbol  2  (Δ 2 )), and one that cannot be inverted is defined as “very poor” (indicated by cross symbol (x)), evaluation was performed on a five level scale. Examples that fall within the scope of the present invention are surrounded by a thick frame in each of Table 1 and Table 2.

     According to Table 1, it can be found that in the range where the upper distance a of the accommodating container  60  is 35 mm or more and 70 mm or less and the distance b is 20 mm or more and 40 mm or less, the ease of inversion is “very good” (indicated by bullseye symbol (⊙)), and the inversion can be easily performed. It can be confirmed that the angle θ 2  within the range of the present invention of the distance a and the distance b is about 20° or more and 40° or less. 
     Example 2 
     Next, under the same conditions as in Example 1, while the distance at which the accommodating container  60  protrudes upward from the upper end portion of the accommodation part  10 B is made constant (in present embodiment, the distance at which the accommodating container  60  protrudes is 10 mm), the ease of extraction of an accommodated object after inverting the inclined part  20 B was evaluated. The results are illustrated in Table 3. While one that can be extracted with almost no finger into the accommodation part  10  is defined as “good” (indicated by circle symbol (∘)), one that can be extracted by putting fingers into the accommodation part  10  is defined as “fair” (indicated by triangle symbol (Δ)), and one that cannot be extracted unless the finger is pushed all the way or cannot be extracted is defined as “poor” (indicated by cross symbol (x)), evaluation was performed on a three level scale. However, as to samples with low evaluations (“fair” (indicated by triangle symbol (Δ 1 )), “poor” (indicated by triangle symbol (Δ 2 )) and “very poor” (indicated by cross symbol (x))) in Table 1 (Example 1), evaluation for extraction in Example 2 was not performed, and the samples were evaluated as unevaluated (−). Examples that fall within the scope of the present invention are surrounded by a thick frame in Table 3.

     According to Table 3, it has been found that in the range where the distance a is 35 mm or more and 70 mm or less and the distance b is 20 mm or more and 40 mm or less, the ease of extraction is “good” (indicated by circle symbol (∘)), and the accommodating container  60  can be easily extracted. Even when the distance a was within the above range (35 mm to 70 mm), when the distance b was 50 mm or more, as illustrated in Table 1, the inverting property was not bad [Sample example (a: 51.5 mm, b: 50 mm), (a: 61.5 mm, b: 50 mm)], but the inverted position where the inclined part  20 E was inverted was located above the upper portion of the accommodating container  60 , and therefore it was necessary to insert fingers to extract the accommodating container  60 . Therefore, the evaluation for extraction was “fair” (indicated by triangle symbol (Δ)). On the contrary, in one having the distance a which was out of the range [sample example (a: 34 mm, b: 37 mm)] even when the distance b was within the range (20 mm to 40 mm), the evaluation of the inverting property in Table 1 was not bad. However, as in the above, the inversion position was located above the upper portion of the accommodating container, and therefore the evaluation of extractability was “fair” (indicated by triangle symbol (A)). In addition, two examples [sample examples (a: 31.5 mm, b: 23 mm), (a: 34.0 mm, b: 23 mm)] of a case where the distance a was smaller than 35 mm were not bad in extractability, but the evaluation of the inverting property in Table 1 was not “very good” (indicated by bullseye symbol (⊙)), and therefore the two examples were out of the range as comprehensive evaluation in which the extractability was added to the inverting property. 
     Example 3 
     Next, the ease of inversion in a case where the position where the medical container  1 B was cut was changed when the accommodating container  60  was extracted was evaluated. As the conditions of the inclined part  20 B, the distance a was set to 41.5 mm, the distance b was set to 27 mm, the angle θ was 33°, and the width d of the accommodation part  10 B was set to 27 mm, and four test specimens were prepared. As illustrated in  FIG. 14 , the boundary part BD of the inclined part  20 B and the rectangular part  30 B was set to a line A, and lines B to D were set every 7 mm above the line A. A test specimen prepared on each line was cut and evaluated for ease of inversion. As a result, it was possible to easily invert the inclined part of the one cut along each of the lines A to C, but it was difficult to invert the inclined part of the one cut along the line D. 
     Although the preferred embodiments of the medical container of the present invention are described above, the present invention is not limited to the above embodiments and can be changed as appropriate. For example, in each of the first to third embodiments, the accommodating container  60  accommodating cells is accommodated as an accommodated object. However, the present invention is not limited to this. That is, an instrument used for medical treatment such as tweezers may be accommodated as an accommodated object. 
     Further, in each of the first to third embodiments, the accommodating opening  70  is provided over the entire length of the upper side of the medical container  1 . However, the present invention is not limited to this. That is, the accommodating opening may be provided only at a portion corresponding to the accommodation part on the upper side of the medical container, and portions corresponding to the extending parts on the upper side may be joined together. Consequently, the opening length of the accommodating opening can be shortened, and therefore it is possible to reduce the risk of contamination inside the medical container when an accommodated object is accommodated. 
     Further, as illustrated in  FIG. 15 , an accommodating opening  70 C may be provided on the lower side of a medical container  1 C (side on the other end side in the height direction HD). In this case, the accommodating opening  70 C may be provided only in a portion between a pair of regulating joining parts  40  on the lower side. The accommodating opening  70 C is provided on the lower side of the medical container  10 , so that an accommodated object can be easily disposed in an accommodation part  10 C (between a pair of the regulating joining parts  40 ). Further, the accommodating opening  70 C is provided only in the portion between a pair of the regulating joining parts  40 , so that the opening length of the accommodating opening  700  can be further shortened, and therefore it is possible to further reduce the risk of contamination inside the medical container  1 C in the state of accommodating the accommodated object. In this case, the accommodating opening may be provided over the entire length of the lower side of the accommodation part ICC. 
     In the third embodiment, an example in which the width d of the upper end portion of the accommodation part  10 B is smaller than the distance a in the width direction WD between the end portion of the upper end portion of the accommodation part  10 B and the end portion of the rectangular part  30 B is illustrated. However, the present invention is not limited to this. For example, as in a medical container  1 D illustrated in  FIG. 16 , the width d of an upper end portion of an accommodation part  10 D may be larger than a distance a in the width direction WD between the end portion of the upper end portion of the accommodation part  10 D and an end portion of a rectangular part  30 D. Consequently, an accommodated object  60 D having a large width can be accommodated. 
     Further, the shape of the accommodation part  10 B is a rectangular shape extending in the height direction HD in the third embodiment, but the shape is not limited to this. The accommodation part may be formed in such a shape as to be able to accommodate according to the shape of the desired accommodating container. Further, the case where the size in the height direction HD of the accommodation part  10 B is smaller than the length of the accommodating container  60  is described, but the present invention is not limited to this. That is, the accommodation part may be configured such that the entire accommodating container  60  is accommodated in the accommodation part. In this case, a person in charge of the unclean field lifts the lower portion of the accommodation part, so that the accommodating container  60  can be protruded from the accommodation part  10 . Thus, the person in charge of the clean field can easily extract the accommodating container  60 .
