  As a fluid storage container, instead of conventional cans and bottles, plastic containers and bag-like containers and bag-like containers have come to be used, such as enteral nutrients used in medical institutions such as hospitals. In many cases, liquid foods or infusions such as medicinal liquids or infusions such as blood are filled in a pouch.

  When taking out the content liquid from such a pouch, it is administered using a catheter connected to the container, and enteral nutrients, liquid food, etc., for example, connect the tube at the proximal end of the catheter to the nozzle of the pouch, The distal end of the catheter is inserted through the mouth or nose and administered to the digestive organ. For infusions such as drug solutions and blood, the catheter is connected to the proximal end of the catheter, for example, by piercing it into a plug such as a pouch rubber. Administration to a blood vessel from an injection needle attached to the tip of the tube is performed.

  For this reason, in the case of enteral nutrients etc., a nozzle-like thing called a spout is attached to the container in advance so that the pouch can be easily opened and can be handled in a sanitary manner. Various proposals have been made that facilitate administration by connecting a tube to the tube.

  For example, in Patent Document 1, as shown in a longitudinal sectional view of FIG. 14 (a) and a BB sectional view of FIG. 14 (b), a cylindrical portion 1 and a cap 2 sealed in a packaging bag as a container. A spout member 3 is disclosed that can be opened by attaching a spout member 3 having the following points and breaking the cylindrical portion 1 by rotation of the cap 2.

  Further, in Patent Document 2, as a container cap device, a pouring tube is disposed at the tip of the container, the pouring tube has a base portion, a tapered body portion, and a stopper plug. It has a stop plug engaging part, and engages with a stop plug when it is fitted to the dispensing tube. When the stopper plug is cut, the unsealing cap is rotated with respect to the dispensing cylinder in a state where the stopper plug engaging portion is engaged.

Thereby, when opening the opening | mouth part of the extraction | pouring pipe | tube, it can be poured out without leaking the liquid in a container, without touching directly with a hand.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1A and 1B show an embodiment of a fluid container dispensing apparatus according to the present invention. FIG. 1A is a plan view of an external appearance, a front view, a bottom view, and FIG. 1B is a longitudinal sectional view before cutting, and a longitudinal section after cutting. FIG. 6C is a cross-sectional view of the cut-out portion and a cross-sectional view in an erroneous use state.
The fluid container pouring device 10 includes a pouring nozzle 20, and the pouring nozzle 20 has a base end attached to a fluid container such as a pouch (not shown) and a cutout portion that can be cut off at the tip. The opening member is integrally provided via the.
As shown in FIG. 1, the dispensing nozzle 20 of the fluid container dispensing apparatus 10 includes a base flange portion 21 serving as a guide for conveyance and container mouth connection at the base end portion, and has a horizontally long planar shape. The base flange portion 21 is provided with a horizontally-long substantially rhombus-shaped connecting portion 22 that protrudes outward in a circular arc shape on the inner side of the container of the base flange portion 21 and has a sharp left and right side. The part and the connecting part 22 can be fixed by welding or the like.

    A substantially cylindrical pouring nozzle body 23 is integrally formed on the container outer side portion of the base flange portion 21 of the pouring nozzle 20 so as to protrude to the center portion, and two flange portions 24 and 25 are provided in the middle portion. It is.

    Of these flange portions 24 and 25 at the intermediate portion, the portion of the pouring nozzle body 23 protruding upward from the upper flange portion 25 is used as the connection portion 26 of the tube of the catheter after opening, and the tip portion is narrowed in a conical shape. The connecting member 26 is integrally formed with an opening member 28 for cutting through a cutting part 27 for cutting.

In this opening member 28, a disk part 29 is formed on the upper part of the connection part 26 of the pouring nozzle body 23, and the operation part 30 for cutting operation projecting at four locations at equal circumferential intervals is formed on the disk part 29. The operation part 30 is rotated around the central axis, pushed up from the lower side, or combined with these rotations and push-ups. Can be done.
In addition, opening of the front-end | tip of the extraction nozzle 20 performed separately from this cutting part 27 is performed by rotating the cover cap which covered the extraction nozzle 20 so that it may mention later.

    In normal use, the opening member 28 is separated from the cutout portion 27 by the operating portion 30 to open the tip of the dispensing nozzle 20, and then the catheter tube, which is a fluid dispensing tube, is placed outside the connection portion 26. Thus, dispensing and administration are performed with the container in an inverted state and the dispensing nozzle 20 facing down.

In order to prevent misuse by inserting a connection needle for infusion for such normal use, the dispensing nozzle 20 of this fluid container dispensing device 10 is as shown in FIG. The inner shape 27a of the cutout portion 27 has a shape in which a gap is formed when they are inserted and fitted to the outer shape 5a of the perfect connecting needle 5, for example, an elliptical shape.
In this cutout portion 27, an outer shape 27c is formed through a thin-walled portion 27b that can be cut into an elliptical inner shape 27a, and has a similar elliptical shape.

    Therefore, in the pouring nozzle 20 of the fluid container pouring device 10 configured as described above, as shown in FIG. 1C, the inner shape 27a is mistakenly infused into the cutout portion 27 of the oval shaped pouring nozzle 20. When a perfect circle connecting needle 5 is inserted / connected, a gap is formed between the elliptical inner shape 27a of the dispensing nozzle 20 and the perfect outer shape 5a of the connecting needle 5. If an attempt is made to pour and administer the container in an inverted state, the liquid content leaks out and it is immediately known that the connection is incorrect, and administration can be stopped.

    In this way, if the inner shape 27a of the cutout portion 27 of the dispensing nozzle 27 is a shape in which a gap is formed with respect to the outer shape 5a of the connection needle 5 for infusion, a misconnection is recognized by leakage of the content liquid. For example, as shown in FIG. 2, the inner shape 27a is formed into a substantially rectangular shape, a cross shape, or a substantially keyhole shape in which a circle and a rectangle are combined. The outer shape 27c of the similar cutout portion 27 may be formed through the thin-walled portion 27b, and in any case, if a true circular connecting needle 5 for infusion is erroneously inserted / connected, it is inserted. However, a gap is formed between the elliptical inner shape 27a of the dispensing nozzle 20 and the perfect outer shape 5a of the connecting needle 5, and if the container is to be poured and administered in an inverted state, the liquid content Is out, we find that it is erroneous connection immediately, administration can be discontinued.

    The inner shape 27a of the cutout portion 27 is not limited to these shapes, and may be other shapes as long as a gap is formed with respect to the outer shape of the connection needle for infusion.

    Further, since the erroneous connection prevention of the dispensing nozzle 27 to the cutout portion 27 is performed by the inner shape 27a, the outer shape 27c of the cutout portion 27 is not necessarily the inner shape 27a and a thin wall portion having a constant thickness. It is not necessary to have a similar shape via 27b, but may be other shapes such as an outer shape of a perfect circle, as long as it can be formed integrally via a thin portion 27b that can be cut off by the operating portion 30 of the opening member 28. good.

Next, in order to prevent an erroneous connection when the connection needle for infusion is inserted without opening the cutout portion 27 with the operation portion 30 of the opening member 28 and opening the cutout portion 27, the fluid container pouring device is provided. 10, the opening member 28 protrudes upward at the center of the disk portion 29 to form an operation portion 30 having a thin plate-like external insertion preventing portion 30 a, and a thin plate-like external portion is formed. A connection needle for infusion cannot be inserted into the mouth of the insertion preventing portion 30a.
Even in this case, the opening at the tip of the dispensing nozzle 20 that is separated from the normal cutout portion 27 is performed by rotating a cover cap that covers the dispensing nozzle 20, as will be described later.
Accordingly, the external insertion preventing portion 30a prevents erroneous connection to the dispensing nozzle simply removed without rotating the cover cap.

    By combining the operation unit 30 including the thin plate-shaped external insertion preventing unit 30a, it is possible to physically prevent an erroneous connection in the unopened state before the opening member 26 is cut off. By using a shape having a gap, an erroneous connection after opening can be physically prevented.

    As shown in FIG. 4, a rectangular or triangular thin plate is combined in a cruciform shape as the external insertion preventing portion 30a of the operation portion 30 for preventing the infusion connection needle from being inserted into the opening member 28 from the outside. However, the present invention is not limited thereto, and any shape such as a convex shape that can prevent the insertion of the connecting needle from the outside may be used.

    Next, another embodiment of the fluid container dispensing apparatus for preventing erroneous connection will be described with reference to FIG. 5. In this fluid container dispensing apparatus 10, the inside of the cutout portion 27 of the dispensing nozzle 20 is provided. An insertion preventing piece 27d for preventing the insertion of a connection needle for infusion is integrally formed, and the inner shape 27a of the cutout portion 27 is a perfect circle and two semicircular shapes by a flat plate shaped insertion preventing piece 27d that partitions it at the center. It is as.

    The insertion preventing piece 27d and the opening member 28 are formed so as to be able to be cut through a thin portion 27e having a thickness substantially the same as the thin portion 27b around the cut portion 27. A portion corresponding to the insertion preventing piece 27d is a recess, thereby forming a thin portion 27e.

    Further, the outer shape 27c of the cutout portion 27 has a perfect circular shape similar to the inner shape 27a through a thin portion 27b having a substantially constant thickness.

    According to such a fluid container pouring device 10, as will be described later, the opening member 28 is rotated through the cover cap that is covered, and the thin portion 27 b and the insertion preventing piece 27 d around the cutout portion 27. The tip of the pouring nozzle 20 can be opened by cutting off the thin-walled portion 27e between them, and if an infusion connection needle is accidentally inserted into the opening, the insertion is prevented by the insertion preventing piece 27d. Is prevented and physical insertion is prevented.

    Further, when the connecting needle for infusion is thin, it may be inserted into two semicircular portions of the inner shape 27a of the cutout portion 27, but a gap is formed between the semicircle and the perfect circle of the connecting needle. When the administration is started with the container in an inverted state, the content liquid leaks out, it is recognized that the connection is incorrect, and the administration can be stopped immediately.

    Further, when an infusion connection needle is to be inserted in an unopened state before the opening member 28 is cut off, a recess corresponding to the insertion preventing piece 27d is formed at the center of the opening member 28. However, the insertion preventing piece 27d is located below the recess, and both end portions of the insertion preventing piece 27d are integrally connected to the inner wall of the dispensing nozzle 20, so that they cannot be inserted and connected. In addition, erroneous connection in an unopened state can be prevented.

    In addition, this insertion prevention piece is not limited to the case where it is integrally formed inside the cutout portion 27 of the dispensing nozzle 20, but, for example, as shown in FIG. You may make it mount from the base end side of the discharge nozzle 20, It comprises the ring part 27f and the trapezoidal plate part 27g of the center part, The both sides | surfaces of the plate part 27g and the inside of the extraction nozzle 20 are comprised. The mounted state is held by the formed protrusion 20a.

    In addition, this insertion preventing piece may be combined with the inner shape of the cut portion already described so as to form a gap with respect to the connecting needle, and it is possible to prevent erroneous connection more reliably. Become.

    Furthermore, the shape of the insertion preventing piece is not limited to a combination of a rectangular or triangular plate shape, but may be other shapes such as a column shape.

Next, the cover cap of the fluid container dispensing apparatus 10 that performs opening operation while covering any of the dispensing nozzles described so far will be described.
7 to 9 relate to one embodiment of the fluid container pouring device of the present invention, and FIGS. 7 (a) and 7 (b) are respectively a longitudinal sectional view and a plan view of the pouring nozzle covered with a cover cap. In the figure, (a) shows a state before cutting, (b) shows a state after cutting, FIG. 8 shows a longitudinal sectional view, a plan view and a bottom view of only the left half of the dispensing nozzle, FIG. It is the longitudinal cross-sectional view of 2 directions which a cover cap orthogonally crosses, a top view, a bottom view, and DD sectional drawing.

    The cover cap 40 of the fluid container pouring device 10 is fitted on the pouring nozzle 20 attached to the container, and is engaged with the opening member 28 via the rotational force from the outside. Used to cut out.

    As shown in FIGS. 7 and 9, the cover cap 40 includes a substantially cylindrical cover cap body 41 applied to the upper flange portion 25 of the dispensing nozzle body 23, and an operation of the opening member 28 on the upper portion thereof. Two opposing U-shaped outer cylinder portions 42 arranged so as to surround the outside of the portion 30 and two conical portions 43 adjacent thereto are provided to cover the outside of the dispensing nozzle 20. It is formed so that it can be done.

    The upper surface of the cover cap 40 is provided in a bridge shape in which a bar-like pressing member 44 connects the upper ends of the outer cylinder portion 42, and the operation portion 30 of the opening member 28 is covered with the cover cap 40 before cutting. It is arranged parallel to the top.

    Further, the cover cap 40 is rotated for a cutting operation, but finger-hooking ribs 41a are provided on the outside of the cover cap main body 41 so as to be easily rotated, and are provided at two locations. The finger hanging rib 41a may be further expanded as necessary.

    In the fluid container pouring device 10 constituted by the pouring nozzle 20 and the cover cap 40 covering the pouring nozzle 20, the opening member 28 provided via the cutout portion 27 of the pouring nozzle 20 is replaced with the cover cap 40. In order to cut off and open by turning, a detaching cam mechanism 45 is provided.

    The separation cam mechanism 45 is provided with a separation cam 46 having a central portion high and inclined on both sides inside the conical portion 43 of the cover cap 40, and a lower surface of the operation portion 30 of the opening member 28 as a cam follower. By rotating the cap 40 about its central axis, the operation unit 30 can be pushed up, whereby the opening member 28 can be separated from the cutout unit 27.

    During the detachment operation, the lower surface of the operating portion 30 of the opening member 28 is pressed by the detaching cam 46, and the upper surface is pressed by the bridge-shaped presser member 44 to hold the cut opening member 28 therebetween. The piece holding means 47 is constituted by a separating cam 46 and a pressing member 44, and the cut piece holding means 47 can hold the cut piece (opening member 28) in the cover cap 40 and can be removed together with the cover cap 40. it can.

    When such an opening member 28 is cut off by being cut off by the separation cam 46 when the cover cap 40 is rotated, if the relative rotation occurs between the dispensing nozzle 20 and the cover cap 40, an opening may be generated. Therefore, a rotation preventing means 50 for preventing this rotation is provided.

    The rotation preventing means 50 between the pouring nozzle 20 and the cover cap 40 is a nozzle plane that is cut out in two planes facing each other across the central axis of the disc-shaped flange portion 25 above the pouring nozzle 20. While forming the portion 51, two cap flat portions 52 are formed so as to protrude inside the corresponding cover cap body 41 of the cover cap 40. Before the opening operation, the nozzle flat surface portion 51 and the cap flat surface portion 52 come into surface contact so that the cover cap 40 cannot be easily rotated. It is designed so that it can rotate over the nozzle flat surface 51 by elastic deformation of 40.

    By providing such a nozzle flat surface portion 51 and a cap flat surface portion 52, it can be used for alignment when assembling the dispensing nozzle 20 and the cover cap 40, and the conical portion 43 and the pressing member 44 of the cover cap 40 can be used. In cooperation with the shape arrangement, the assembly work can be facilitated as a mark.

    In addition, as shown in FIG. 8 and FIG. 9, the nozzle plane part 51 and the cap plane part 52 provided as the rotation preventing means 50 are formed at two opposing positions, as shown in FIG. In addition, there may be three places at equal intervals around the circumference, or four places as shown in FIG.

    Furthermore, the cap flat surface portion 52 of the cover cap 40 functioning as the rotation preventing means 50 is not limited to one constituted by a continuous straight line. For example, as shown in FIG. The flat portion 52 may be provided, and the flat portion in this case may be further increased in addition to the case where two portions are provided at equal intervals around the circumference.

    In such a fluid container pouring device 10, it is necessary to prevent relative rotation of the cover cap 40 and to prevent the cover cap 40 from coming off in the axial direction until the opening operation is completed. It is provided.

The disengagement prevention means 60 of the cover cap 40 uses the flange portion 25 above the pouring nozzle 20, and hooks a locking protrusion 61 that protrudes to the inside of the lower end of the cover cap body 41 of the cover cap 40 on its lower surface. While preventing the disengagement by locking, the outer periphery of the rotation preventing means 50 formed in the flange portion 25 is cut away by the nozzle flat portion 51 so that the locking protrusion 61 is not caught. Thus, the lock can be released.
When the nozzle flat surface portion 51 is not provided, the cover cap body 41 can be elastically deformed and lifted to release the lock.

    On the other hand, in this disengagement prevention means 60, when the cover cap 40 is put on the dispensing nozzle 20, the locking projection 61 is positioned other than the nozzle flat surface portion 51 of the upper flange portion 25 and is locked. In the state where the cover cap 40 is rotated and the opening member 28 is separated by the separation cam 46 and the separation is completed, the locking projection 61 can be positioned on the nozzle flat surface portion 51 to be opened. It is like that.

    As described above, the nozzle flat portion 51 of the rotation preventing means 50 is used for preventing the cover cap 40 from rotating, and at the same time, used for releasing the locking projection 61 of the removal preventing means 60 of the cover cap 40. This also serves to simplify the structure and facilitate manufacture.

    Furthermore, in this fluid container pouring device 10, the cover cap 40 is turned off and the opening member 28 of the pouring nozzle 20 is cut off to complete the opening. In order to clearly know this and to be able to remove the cover cap 40, a cover cap removal cam mechanism 70 is provided. To move to.

    In this cover cap removal cam mechanism 70, a pair of removal cams 71 projecting downward on the inner periphery of the lower portion of the cover cap 40 is formed across the central axis, and a cam follower 72 corresponding to these removal cams 71 is provided for the dispensing nozzle 20. The upper flange portion 25 is formed so as to protrude from two locations on the upper surface.

By rotating the cover cap 40 with the detaching cam 71 and the cam follower 72, the cover cap 40 can be lifted up so as to push it outward in the axial direction.
Accordingly, it can be seen that the cover cap 40 may be removed from the dispensing nozzle 20 and that the locking of the cover cap 40 detachment preventing means 60 is released.

    In addition, when only the locking protrusion 61 is provided as the means 60 for preventing the cap cap 40 from being removed and the nozzle flat portion 51 is not provided, the nozzle flat portion 51 is not opened depending on the rotation position. By lifting the cap 40 with the removal cam 71, the locking protrusion 61 can be elastically deformed to release the locking.

In such a fluid container dispensing apparatus 10, as shown in FIG. 7A, a cover cap 40 is placed on a fluid container (not shown), for example, a dispensing nozzle 20 attached to the mouth of a pouch by welding or the like. Then, the locking protrusion 61 of the disengagement preventing means 60 is hooked and locked to the flange portion 25 other than the nozzle flat surface portion 51 of the rotation preventing means 50.
Thereby, the cover cap 40 is hold | maintained, without removing from the extraction nozzle 20, and the extraction nozzle 20 can be kept hygienic.

    Further, in this state, the disc portion 29 of the opening member 28 and the operation portion 30 that are integrally provided at the tip end portion of the dispensing nozzle body 23 of the dispensing nozzle 20 via the cutout portion 27 are the outer cylinder of the cover cap 40. While being surrounded by the portion 42 and the conical portion 43, the upper surface of the opening member 28 and the pressing member 44 of the dispensing nozzle main body 23 are separated from each other by a slight gap.

    Further, the nozzle flat portion 51 of the pouring nozzle 20 constituting the rotation preventing mechanism 50 and the cap flat portion 52 of the cover cap 40 are in surface contact with each other, and the cover cap 40 is in such a degree that a slight force is applied to the cover cap 40. 40 cannot be rotated, and the opening member 28 is prevented from being inadvertently cut off.

    Further, the separation cam 46 of the separation cam mechanism 45 is positioned 90 degrees away from the operation portion 30 of the opening member 28 in the rotational direction, and the removal cam 71 of the cap removal cam mechanism 70 is in a state before being pushed up. It faces the cam follower 72 of the flange portion 25 of the dispensing nozzle 20 or is in contact therewith.
