  However, in the medical waste storage bags of Patent Documents 1 and 2, the medical waste may be caught by a false gusset by a gusset or a middle sheet, and smooth insertion may be difficult. In addition, the opening is stretched by the peripheral fusion part, and the opening cannot be sufficiently opened for a rheumatic patient or the like, which may make insertion difficult.

  Therefore, the present invention provides a medical waste storage bag capable of opening an opening stably and widely.

  The sheet-type medical waste storage bag according to the present invention has a back surface sheet and a front surface sheet, which are flexible synthetic resin sheets, welded at the periphery, and has a gusseted portion at the bottom to serve as the storage area. A sheet-type storage bag having an opening that leads to the storage area via an insertion path, and a constriction that is recessed from the side from the opening to the insertion path.

  Further, the constricted portion has a linear portion that inclines linearly from above the opening portion inward on both sides of the bag, a curved portion that curves from the lower end of the linear portion, and a horizontal direction from the end of the curved portion. It is preferable that the horizontal part is located at the upper edge of both sides of the storage area.

  Moreover, it is preferable to provide the drawstring which welds to the opening part formed in a surface sheet, and to have the 2nd welding part welded to the said drawstring also in the position which corresponds to the insertion path of the said surface sheet.

  The second welded portion is located at the center in the width direction of the insertion path, and is formed linearly in the longitudinal direction of the bag body. The second welded portion is below the horizontal portion from the straight portion of the side constricted portion. It is preferable that it is formed all the way.

  According to the first aspect of the present invention, it is possible to provide a margin at the side edge of the bag body composed of the top sheet and the back sheet by the constricted portion, and to form a storage area and an insertion path therein, and the bag body by opening the opening portion. The deformation of the constricted portion can be made to follow the deformation to prevent the side edge from being stretched, and the opening can be opened stably and widely.

  According to the second aspect of the present invention, the medical waste can be smoothly guided between the curved portions by the inclination of the side edge from the opening to the curved portion. In addition to this, when the opening of the opening is not solid, the user can securely open the opening and the insertion path by holding the constricted portion, and the state can be easily visually confirmed.

  According to the third aspect of the invention, the surface sheet around the constricted portion can be stably deformed by the drawstring, and the insertion path can be reliably opened.

  According to the fourth aspect of the present invention, since the second welding portion is formed in the insertion path and reaches the storage area, the insertion path can be reliably opened by pulling the pull string.

It is a front view around the opening part of the medical waste storage bag which opened the opening part. It is XX sectional drawing which shows typically the state which inserts medical waste in the medical waste storage bag of FIG. It is the whole front view of the medical waste storage bag which stored the medical waste.

  An embodiment of the present invention will be described. In the present description, the description will be made with the paper surface of FIG.

  As shown in FIGS. 1 and 2, the medical waste storage bag according to the present embodiment forms a sheet-type bag body 1 having a storage area A inside by overlapping two flexible synthetic resin sheets. . That is, the left and right side edges and the lower edge are overlapped with the back sheet 2 having the vertical direction as the longitudinal direction and the top sheet 3 having the same width in the width direction as the back sheet 2 (length in the left and right direction in FIG. 1). Are formed into a rectangular bag 1. The bag body 1 is formed with a gusset portion 16 by folding at the lower end portion (bottom portion) in the longitudinal direction, and can store a predetermined capacity.

  Although the storage area A can be enlarged by the gusset portion 16, it is a sheet-like (flat plate-like) bag body 1 in a normal state. That is, the thickness is just the overlap of the top sheet 3 and the back sheet 2, and even if it reaches the periphery of the gusset portion 16, the folding for forming the gusset portion 16 has a certain thickness. In the state of use, the bag body 1 has a storage area A that can store two medical wastes 20 such as auto injectors.

  In this description, the storage area A indicates a portion having the bottom of the bag body 1 as a bottom edge and a horizontal portion 8 of the constricted portions 5 and 5 described later as an upper edge. The insertion path B is a portion from the opening 4 to the storage area A, and indicates a portion that is tapered by the constricted portions 5 and 5.

  The back sheet 2 is formed longer in the longitudinal direction than the upper edge (opening 4) of the top sheet 3, and the upper part serves as a folding lid 14 described later. The upper edge of the top sheet 3 is not welded to the back sheet 2, and the medical waste 20 can be inserted into the storage area A by using this portion as the opening 4. The width of the opening 4 in the left-right direction is shorter than the width of the bag 1 in the left-right direction. For example, the width of the bag 1 is 121 mm, the width of the opening 4 is 100 mm, and the welded portion of the opening 4 is excluded. The width of the opening range is 98 mm.

  The bag body 1 has constricted portions 5 and 5 that are recessed from both sides to the inside in the width direction from directly above to below the opening 4. That is, the constricted portions 5, 5 are straight portions 6, 6 that are cut linearly from both sides of the bag body 1 inward in the width direction, and curved portions 7, 7 that are curved from the lower ends of the straight portions 6, 6, It has the horizontal part 8 which becomes a horizontal direction toward the both sides from the termination | terminus (lower end) of the curved parts 7 and 7. FIG. Specifically, the horizontal portions 8 and 8 of the constricted portions 5 and 5 are located 20 mm below the opening 4 and are provided on both sides (both left and right). The most constricted positions (curved portions 7, 7) of the constricted portions 5, 5 are formed so as to be recessed 20 mm from the side edge of the bag body 1 to the left and right inner sides.

  By forming the constricted portions 5 and 5, the insertion path B from the opening 4 to the storage area A can be formed. That is, the constricted portions 5 and 5 are formed so that the inside of one end narrows from the opening 4 to the storage region A, and the horizontal portions 8 and 8 of the constricted portions 5 and 5 clarify the upper end of the storage region A. The storage area A itself is a substantially rectangular bag.

  By having the curved portions 7, 7 of the constricted portions 5, 5, a margin can be provided on the side edge of the bag body 1, and the deformation of the constricted portions 5, 5 can be caused by the deformation of the bag body 1 by opening the opening 4. I'm following you. By this follow-up, the opening 4 can be opened (deformed) without causing problems such as side edge tension, and the opening 4 can be opened widely and stably. Then, the length of the side edge of the insertion path B is made longer by the constricted portions 5 and 5 than the vertical distance from the opening 4 to the upper end of the storage area A, and the opening 4 and the constricted portions 5 and 5 are deformed. It is easy to do. Further, by narrowing the left and right widths by the constricted portions 5 and 5 rather than the left and right widths of the opening 4, it is possible to prevent the stored medical waste 20 from being stored in a reverse or sideways posture. doing.

  A pulling string 9 for opening the opening 4 is provided in the opening 4 of the top sheet 3. The drawstring 9 is a substantially rectangular flat plate sheet having its upper end fixed to the upper edge (opening 4) of the top sheet 3 by welding and extending downward. The drawstring 9 is made of a belt-like flexible synthetic resin sheet, and has a left and right width of 55 mm, and is shorter than the narrowest portion (66 mm) between the constricted portions 5 and 5 of the bag body 1.

  The drawstring 9 is extended in the longitudinal direction, and is extended so that the tip (lower end) thereof is located until reaching the vicinity of the longitudinal center of the bag body 1. The lower end portion of the drawstring 9 has a circular through-hole as the finger hook portion 10.

  The drawstring 9 is welded at the upper edge (opening 4) of the topsheet 3. In addition to this, the topsheet 3 has a second welded portion 11 at a portion having the constricted portions 5 and 5. The second welding portion 11 fixes the drawstring 9 to the topsheet 3 and reinforces the fixation of the drawstring 9 to the topsheet 3. The second welded portion 11 is located in the center of the left and right widths of the insertion path B and is formed in a straight line shape along the vertical direction. The second welded portion 11 has a vertical dimension of 25 mm and is longer than the vertical dimension (15 mm) so as to be positioned near the lower end of the curved portion 7 of the constricted portion 5. The lower end of the second welded portion 11 is positioned slightly below the horizontal portion 8 of the constricted portions 5 and 5, and the insertion path B can be appropriately opened when the pulling cord 9 is pulled.

  Further, the drawstring 9 is provided with curved portions 12 and 12 that are recessed inwardly on the left and right sides of the portion having the second welded portion 11, and the second welded portion is not a straight line shape along the vertical direction of the side edge of the drawstring 9 The shape has a curve at the 11 position. The curved portions 12 and 12 have the same vertical dimension as the vertical dimension of the second welded portion 11.

  The back sheet 2 is formed to be vertically longer than the top sheet 3 and projects upward from the opening 4. The protruding portion of the back sheet 2 has a bent portion 15 above the opening 4 to form a folded lid 14. The folding lid 14 can be folded back toward the top sheet 3 to cover the opening 4.

  The bent portion 15 is located (displaced upward) from the opening 4 via a margin of about 6 mm, and even if a crease occurs in the bent portion 15, it is difficult to interfere with the opening 4. Then, when the opening 4 is opened by making the side edge extending from the portion forming the upper end of the opening 4 to the bent portion 15 into an inclined linear shape (straight line portion 6) aligned with the side edge of the insertion path B, etc. Thus, the force is concentrated on the left and right ends of the opening 4 to prevent the insertion path B from being damaged.

  The folding lid 14 is locked to the top sheet 2 in a state of covering the opening 4 by the locking means. The locking means is made up of hook-and-loop fasteners 13 and 13 arranged on the left and right sides, and is respectively arranged near the side edge of the bag body 1 below the opening 4. The hook-and-loop fasteners 13 and 13 are positioned above the tip of the folded lid 14 (the lower end in the folded state), and the distal end of the folded lid 14 is positioned at substantially the same height as the upper end of the finger hook 10.

  A method of using the medical waste storage bag of this embodiment will be described by taking as an example a case where a used autoinjector is used as the medical waste 20 to be stored. First, from the state where the folding lid 14 shown in FIG. 1 is locked, a hand is inserted between the top sheet 3 and the folding lid 14 from below to release the hooking of the hook-and-loop fasteners 13, 13, and the folding lid 14 is moved. Returning upward, the opening 4 is exposed. Note that the hook 9 may be lifted forward by passing the finger through the finger hook 10 and the hook-and-loop fasteners 13 and 13 may be unlocked.

  Next, as shown in FIG. 3, a finger is passed through the finger hook 10 and the pulling string 9 is pulled downward to open the opening 4 greatly. In this way, the opening 4 can be easily opened largely even by a patient who has difficulty in fingers with the drawstring 9. Then, the drawstring 9 is deformed without stretching the portion of the drawstring 9 that overlaps the insertion path B following the insertion path B opened in a conical shape by the curved portions 12, 12, and the second welded portion 11 opens the opening 4. There is no hindrance.

  The used medical waste 20 can be inserted into the opened opening 4, and the medical waste 20 can be stored in the storage area A from the insertion path B. At this time, the straight portions 6 and 6 and the curved portions 7 and 7 of the constricted portions 5 and 5 are prevented from being caught and guided downward, thereby smoothly inserting the medical waste 20.

  The normal form of use is as described above. However, when the opening 4 does not open firmly and wide by pulling the pull string 9, the user grasps the opening 4 by holding the constricted portions 5 and 5 on both sides. It is possible to open and easily recognize the open state. The constricted portions 5 and 5 have a function of assisting the opening of the opening 4.

  With the medical waste 20 disposed in the bag, as shown in FIG. 5, the folding lid 14 is folded back, and the folding lid 14 is locked by the hook-and-loop fasteners 13, 13 to complete the storing operation. And the movement of the medical waste 20 stored by the constricted portions 5 and 5 and the horizontal portions 8 and 8 to the left and right inner side (return to the opening 4 side) is suppressed, and the second medical waste 20 is removed. The medical waste 20 previously stored when inserting it is made difficult to get in the way.
