FIG. 4 is a drawing for explaining the state in which the opening of the soft medical container 1 is opened, and FIGS. 5 and 6 are partially enlarged views of the soft medical container 1. For convenience of the following description, the vertical direction of the paper surface of FIG. 1 is referred to as the “vertical direction” of the soft medical container, and the direction orthogonal to the “vertical direction” is referred to as the “width direction”. The "vertical direction" is equal to the longitudinal direction of the central axis of the soft medical container.

  The medical soft container 1 shown in FIGS. 1 to 6 includes a container body 2 and a discharge port 5 fixed to the discharge port 26 of the container body 2. The container body 2 includes a container 21 for containing the liquid material, and a pair of finger insertion units 221 and 222 disposed below the container 21 (hereinafter, “the finger insertion unit 221 And an "insertion unit 221" and a "finger insertion unit 222" also referred to as a "second finger insertion unit 222".

  The container body portion 2 includes a peripheral edge joint portion 23 formed by heat bonding (heat sealing) or the like between three sides of the outer peripheral edge portions of the first surface portion 3 and the second surface portion 4, Between the first surface portion 3 and the second surface portion 4 in the upper portion of the container main body portion 2, an opening 24 connected to the accommodation portion 21 is provided. When the container 21 is filled with the liquid, the opening 24 is located above the container 21. On the first surface portion 3 and the second surface portion 4, graduations for confirming the amount of the liquid material injected into the storage portion 21 are displayed.

  In the inner surface of the container body 2, below the finger insertion portions 221 and 222, a zip 25 (retractable opening and closing engaging portion) that allows the accommodating portion 21 to be freely opened and closed with respect to the outside of the accommodating portion 21 , Also known as "chuck seal". The zip 25 can be molded by a conventionally known method.

  As clearly seen from FIG. 3, the first surface portion 3 has a relatively smaller area than the first sheet 31 having a relatively large area, and the heat is applied to the inner surface above the zip 25 of the first sheet 31. And a first inner sheet 31a joined by adhesion or the like. The first inner sheet 31a has at least a first upper edge and a lower edge so as to form at least one opening that is open in the width direction in order to enable insertion of a finger from the width direction. It is joined to the sheet 31.

  Here, when a portion of the first sheet 31 constituting the finger insertion portion 221 is referred to as a first outer sheet 31 b, the first surface portion 3 is disposed above the accommodation portion 21 and the first inner sheet A first finger insertion portion 221 including a finger 31a and a first outer sheet 31b and capable of inserting a finger between the first inner sheet 31a and the first outer sheet 31b from the width direction is included. Since the lengths in the vertical direction of the first inner sheet 31a and the first outer sheet 31b that constitute the first finger insertion portion 221 are equal, the first inner sheet 31a and the first outer sheet 31b are stacked without slack. There is. As shown in FIG. 1 and the like, the upper edge portion and the lower edge portion of the first finger insertion portion 221 are respectively a first upper edge joint portion 221c in which the first outer sheet 31b and the first inner sheet 31a are joined. And a first lower edge joint 221d.

  On the other hand, as can be clearly seen from FIG. 3, the second surface portion 4 has a smaller area than the second sheet 41 having a relatively large area and the second sheet 41, and the inner surface above the zip 25 of the second sheet 41. And a second inner sheet 41a joined thereto. The second inner sheet 41a has at least a second upper edge and a second lower edge so as to form at least one opening that is open in the width direction in order to allow insertion of a finger from the width direction. It is joined to the sheet 41.

  Here, assuming that a portion of the second sheet 41 that constitutes the finger insertion portion 222 is referred to as a second outer sheet 41 b, the second surface portion 4 is disposed above the housing portion 21 and the second inner sheet 41a and a second outer sheet 41b, and includes a second finger insertion portion 222 which enables insertion of a finger between the second inner sheet 41a and the second outer sheet 41b from the width direction. Since the lengths in the vertical direction of the second inner sheet 41a and the second outer sheet 41b constituting the second finger insertion portion 222 are equal, the second inner sheet 41a and the second outer sheet 41b are stacked without slack. There is. As shown in FIG. 2 and the like, the upper edge portion and the lower edge portion of the second finger insertion portion 222 are respectively a second upper edge joint portion 222c in which the second outer sheet 41b and the second inner sheet 41a are joined. And a second lower edge joint 222d.

  In the following, when "first inner sheet" and "second inner sheet" are abbreviated as "inner sheet" and "first outer sheet" and "second outer sheet" are abbreviated as "outer sheet". There is. Also, both the "first upper edge joint" and the "second upper edge joint" will be abbreviated as "upper edge joint", and both the "first lower edge joint" and the "second lower edge joint" It may be abbreviated as "lower edge joint".

  As shown in FIG. 1, in each of the first inner sheet 31a and the first outer sheet 31b of the first finger insertion portion 221, first vertically elongated holes 6b, 6a are formed along the vertical direction of the container body 2. ing. The first vertically elongated holes 6 b, 6 a are formed at the same position in the width direction of the soft medical container 1. As shown in FIG. 2, second longitudinally elongated holes 7 b and 7 a along the vertical direction of the container body 2 are formed in each of the second inner sheet 41 a and the second outer sheet 41 b of the second finger insertion portion 222. ing. The second longitudinally elongated holes 7b are formed at the same position in the width direction. Hereinafter, both the "first vertically elongated holes" and the "second vertically elongated holes" may be abbreviated as "long vertically elongated holes". Moreover, in the present application, the “longitudinal hole” refers to a hole whose length in the vertical direction is longer than the length in the width direction.

As shown in FIG. 4, for example, the thumb of a finger of one hand is inserted into the first finger insertion portion 221 with respect to the medical soft container 1 in which the closed state of the storage portion 21 is released by opening and closing means such as zip 25. A finger other than the thumb of the finger of one hand (for example, a forefinger) is inserted into the second finger insertion portion 222, and the first finger insertion portion 221 and the second finger insertion portion 222 are separated from each other. As long as the forefinger is away from each other, a vertically elongated hole is formed in each of the first finger insertion portion 221 and the second finger insertion portion 222, so that the pair of finger insertion portions 221 and 222 is formed with the vertically elongated hole as a valley portion. Each bend in a V shape. Therefore, the following property of the sheet with respect to the finger is good, and the opening 24 is widely opened, so the opening operation of the opening 24 is easy to be performed. When the opening 24 is opened, the opening 24 has, for example, a substantially rhombus shape as viewed from the injection direction of the liquid material into the storage unit 21. Moreover, in the soft medical container 1 shown in FIGS. 1 to 6, since the holes are formed in both the inner sheet and the outer sheet, not only the following property of the sheet to the finger is improved, but also the finger and excursion becomes widely, thus opening 2 4 Gayori large easy open, easy opening operation of the opening 24 is performed more.

  The positions of the first vertically elongated holes 6b and 6a and the second vertically elongated holes 7b and 7a in the finger inserting portions 221 and 222 are determined by the fingers inserted in the finger inserting portions 221 and 222, respectively. There are no particular limitations as long as the holes are bent as valleys and bent in a V-shape. The tips of the fingers inserted into the finger insertion portions 221 and 222 may not reach the first longitudinal holes 6b and 6a and the second longitudinal holes 7b and 7a, respectively, but, for example, the first longitudinal holes 6b, 6a and at least one of the second vertically elongated holes 7b and 7a are closer to the finger insertion start ends 221a and 222a of the finger insertion units 221 and 222 than the tips of the fingers inserted in the finger insertion units 221 and 222. Preferably, the first longitudinal elongated holes 6b and 6a and the second longitudinal elongated holes 7b and 7a are formed closer to each other than the tips of the fingers inserted in the finger insertion portions 221 and 222. More preferably, it is formed near the insertion start end 221a, 222a of the finger 222. Also, for example, it is preferable that the vertically elongated holes be formed at positions closer to two thirds of the full width of the housing 21 from the finger insertion start ends 221a, 222a of the finger insertion parts 221, 222, More preferably, it is formed at a half position of the full width.

  In FIG. 4, the thumb inserted in the first finger insertion portion 221 penetrates the first vertically elongated hole 6 b and protrudes from the first outer sheet 31 b to the outside of the first finger inserted portion 221, and the first vertically elongated hole 6 b The first outer sheet 31b, which constitutes the outline of the above, rests on the finger. A finger (for example, a forefinger) other than the thumb of the finger of one hand inserted into the second finger insertion portion 222 penetrates the second vertically elongated hole 7 b and protrudes from the second outer sheet 41 b to the outside of the second finger insertion portion 222 The second outer sheet 41b constituting the contour of the second vertically elongated hole 7b is mounted on the finger. Therefore, since the working area of the finger is further expanded, the opening 24 can be further enlarged, and the opening operation of the opening 24 can be performed more easily. In addition, since the outer sheet constituting the outline of the first vertically elongated holes 6b and the second vertically elongated holes 7b is placed on the finger, the storage portion 21 is heavy during the pouring of the liquid into the storage portion 21. Even in the case, the soft medical container 1 can be stably held. A longitudinally long hole may be formed in the finger insertion portion so that only one of the fingers inserted into the finger insertion portions 221 and 222 penetrates the longitudinally long hole.

  In the embodiment shown in FIGS. 1 to 6, longitudinally elongated holes are formed not only in the first outer sheet 31b and the second outer sheet 41b but also in the first inner sheet 31a and the second inner sheet 41a. Since the longitudinally elongated hole of the first finger insertion portion and the longitudinally elongated hole of the second finger insertion portion are formed at the same position in the width direction of the soft medical container 1, in the process of manufacturing the soft medical container, Both the longitudinal holes and the longitudinal holes of the second finger insertion part can be simultaneously formed by cutting, which improves productivity of the soft medical container, which is preferable.

  As shown in FIGS. 1 and 2, the contours of the upper end portions of the first vertically elongated holes 6a, 6b and the second vertically elongated holes 7a, 7b are arc-shaped. And in the portion below the upper end, the width of the hole is gradually widened from the lower end to the upper end. Therefore, as shown in FIG. 4, when the first finger insertion portion 221 and the second finger insertion portion 222 are pulled apart from each other, the first finger insertion portion 221 and the second finger insertion portion 222 have the vertically elongated holes 6 a. , 7a is bent so as to hide the opening 24 by the first inner sheet 31a and the second inner sheet 41a. Therefore, even if the longitudinally elongated holes 6a and 7a are formed in the first inner sheet 31a and the second inner sheet 41a, the finger in the vicinity of the longitudinally elongated holes 6a and 7a of the first inner sheet 31a and the second inner sheet 41a And the finger is substantially isolated from the opening 24 and the contamination of the liquid is also suppressed.

  When the liquid material is injected into the containing portion 21, the sheet forming the finger inserting portion is pressed against the finger penetrating the vertically elongated hole, and as a result, particularly, the width of the upper portion of the opening of the vertically elongated hole is narrow. Become. In order to improve the followability of the sheet to the finger or to widen the movable range of the finger, it is preferable that the width of the opening portion of the vertically elongated hole is wide. Therefore, from the viewpoint of improving the followability of the sheet to the finger or expanding the movable range of the finger to improve the opening operation of the opening, as shown in FIGS. It is preferable that the upper part thereof has a relatively larger area than the lower part. In addition, a portion of the first inner sheet 31a and the second inner sheet 41a in the vicinity of the vertically elongated holes 6a and 7a substantially conceals the finger from the opening 24, thereby suppressing contamination of the finger by the liquid material. Therefore, it is preferable that the lower part of the openings of the vertically elongated holes have a relatively smaller area than the upper part.

  In the case of using the vertically elongated hole as the hanging hole, from the viewpoint of dispersing the load due to the weight of the liquid, it is preferable that R of the arc be larger, for example, 5 mm or more and 10 mm or less.

  There is no restriction | limiting in particular about the material of the 1st surface part 3 and the 2nd surface part 4, The conventionally well-known soft plastic sheet used for manufacture of the soft medical container 1 can be used. Specifically, for example, a monolayer sheet made of vinyl chloride resin, polyethylene, ethylene-vinyl acetate copolymer, polyester, polybutadiene, polypropylene, polyamide, ethylene-methacrylate copolymer, etc., or the monolayer sheet is laminated. Laminated sheet. Specific layer configurations of the laminated sheet include, for example, nylon / polyethylene, nylon / polypropylene, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, nylon / polypropylene / polyethylene and the like. The thickness of the soft plastic sheet is, for example, about 0.01 mm or more and 0.3 mm or so.

  The discharge port 5 is, for example, tubular. The discharge port 5 is fixed to the container body 2 by being sandwiched between the first surface 3 and the second surface 4 at the discharge port 26 so that the inside and the outside of the container body 2 can be communicated.

  The discharge port 26 and the discharge port 5 are disposed on the extension of the vertical center line A which bisects the housing portion 21 in the width direction. The fixing of the discharge port 5 to the container body 2 is performed by disposing the discharge port 5 between the first sheet 31 and the second sheet 41 at the discharge port 26, so that the first sheet 31 and the second sheet 41 are fixed. This can be done by thermally bonding the outer peripheral edge portions of

  Examples of the material of the discharge port 5 include cyclic polyolefin, polycarbonate, polyethylene terephthalate, polypropylene, polyethylene naphthalate, EVA (ethylene vinyl acetate copolymer), polyethylene and the like.

  When the discharge port 26 and the discharge port 5 are arranged on the extension of the vertical center line A, the first vertical long holes 6a and 6b and the second vertical long holes 7a and 7b are also formed on the extension of the vertical center line A If it does, 1st vertical long hole 6a, 6b and 2nd vertical long hole 7a, 7b can also serve as a hanging hole for hanging the medical soft container 1 to a stand etc.

  The width of the finger insertion parts 221 and 222 is obtained by bending the side of the finger insertion parts 221 and 222 including the insertion start side ends 221 a and 222 a of the finger insertion parts 221 and 222 among the width direction both sides of the container body 2. Is narrower than the width of the housing portion 21. Therefore, while providing the first longitudinally elongated holes 6a, 6b and the second longitudinally elongated holes 7a, 7b on the extension of the vertical center line A, and from the insertion start side ends 221a, 222a, the first longitudinally elongated holes 6a, 6b and the second longitudinally elongated At least one of the fingers inserted in the finger insertion portions 221 and 222 is allowed to reach the longitudinally elongated holes, preferably both of them are allowed to reach the longitudinally elongated holes, and further preferably at least one is longitudinally elongated. It is easy to set such that it is possible to penetrate the hole, and even more preferably both.

  When the extension line of the vertical center line A coincides with the central axes of the first vertically elongated holes 6a, 6b and the second vertically elongated holes 7a, 7b, the first vertically elongated hole and the second vertically elongated hole are inserted from the insertion start side 221a, 222a. The distance to the central axis is preferably 40 mm or more and 80 mm or less, more preferably 40 mm or more and 60 mm or less, from the viewpoint of improving the opening operability of the opening 24 and the retention of the soft medical container 1.

  At the first finger insertion portion 221, the insertion start side ends 221a and 222a of the fingers of the second finger insertion portion 222, and in the vicinity thereof, the first notch 32 and the second notch are formed in the first outer sheet 31b and the second outer sheet 41b. The notch portion 42 is formed, and the inner side surface of the first inner sheet 31 a and the inner side surface of the second inner sheet 41 a are exposed from the first notch portion 32 and the second notch portion 42, respectively. Therefore, it is easy to insert a finger into the internal space 221 g of the first finger insertion part 221 and the internal space 222 g of the second finger insertion part 222.

  The maximum lengths in the vertical direction of the first notch 32 and the second notch 42 are the first vertically elongated holes 6a and 6b and the second vertically elongated holes from the viewpoint of securing the movable range of the finger in each finger insertion portion. The positions of the first and second longitudinally elongated holes 6a and 6b and the second longitudinally elongated holes 7a and 7b are greater than the maximum length in the vertical direction of 7a and 7b. It is preferable that they completely match.
