Nutritional therapy using PEG tube is a nourishment of patient by PEG tube without oral administration. (A so-called gastrostomy) is formed through the abdominal wall of the patient and a tube (PEG tube) is installed percutaneously.

On the other hand, oral nutritional therapy involves inserting a flexible tube (called a guinea tube) from the nasal cavity to the intestine of a patient and introducing nutrients, drugs, liquids (Hereinafter, simply referred to as " nutritional agent ") such as a liquid or a liquid.

In a conventional medical container, a cap is provided at a port so that the inside of the container is sealed. When administering the liquid in the container, the operator breaks the internal seal first (opens to the outside) by making a hole in the cap. Then, one end of a guard tube or a PEG tube (or a sap tube connected to the PEG tube) is connected to a hole formed in the cap by using a predetermined nozzle-shaped connector (hereinafter simply referred to as a "nozzle"). At this time, the cap and the nozzle may be locked to each other so as not to be easily released. Then, the nutrient is distributed to the tube, and nutrition is administered to the patient from the other end of the tube.

≪ Embodiment 1 >

(Nutritional administration set (1))

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a diagram showing the constitution of a nutrient administration set (1) according to Embodiment 1. Fig. 2 is a diagram showing the respective constitutions and connection methods of the cap 15 and the nozzle 20 in the nutrient administration set 1. Fig.

The nutrient administration set (1) shown in Fig. 1 is composed of a nutrient container 10 and a liquid tube 30, which are examples of medical containers. The nutrient container 10 comprises a flexible bag 100 in which two rectangular resin films are joined at the edges and a port (opening) 101 communicating with the inside is provided at one side of the edge, And a cap 15 connected thereto. In the bag 100, an enteral nutrient of the liquid material is stored. In the cap 15, the inside of the bag 100 is sealed. As a result, the enteral nutrient remains sterile.

In this embodiment, a flexible container is used as the bag 100, but this is merely an example of a medical container, and other known medical containers such as a paper pack, a glass bottle, a metal container, and a syringe may be used.

As a matter of course, the liquid material to be stored in the container is not limited to the enteral nutrient, but may be other than the intravenous administration, and may be various anticancer materials such as various nutrients to be administered to the patient.

The cap 15 is integrally formed of a resin material, and is mounted on a port (liquid-permeable portion) 101 to seal the inside of the bag 100. The cap 15 also serves as a connector for connecting the bag 100 side to the nozzle 20. [ As shown in Fig. 2, the nutrient administration set 1 constitutes a pair of connector sets in which the cap 15 and the nozzle 20 are connected to each other. The inner seal of the bag 100 is broken by the operation when the operator performs a predetermined locking operation to be described later so that the nutrient inside the bag 100 is sucked into the sap tube 30 side via the cap 15 . Therefore, in the nutrient administration set 1, when the cap 15 and the nozzle 20 are connected to each other, the nutrient in the bag 100 does not come in contact with the outside air. Accordingly, in the nutritional administration set (1), the nutritional agent can be kept extremely hygienic up to just before the administration and during the administration, and the nutritional agent with high stability can be administered to the patient.

The infusion tube 30 is a liquid infusion line made of a resin material such as silicone resin or polyvinyl chloride having appropriate flexibility and has a connector (nozzle 20) for connecting to the cap 15 at its upstream end, And an insertion portion 33 in which a predetermined port is formed in order to administer the nutrient to the patient side is disposed at the downstream side end portion. In the middle of the fluid tube 30, a known pointed cylinder 31 and a clamp 32 are provided.

When the nutrient administration set (1) is used, the bag (100) is placed on a predetermined stand so that the port (101) faces downward. 2, the nozzle 20 is connected to the cap 15 connected to the port 101, and the connection state is locked. Thereafter, the nutrient inside the bag 100 is infused into the patient through the infusion tube 30.

Hereinafter, the cap 15 and the nozzle 20 will be described in detail.

(Cap 15)

Fig. 3 (a) is a view showing the appearance of the cap (mail connector) 15. Fig. 3 (b) is a cross-sectional view showing the internal structure of the cap 15. Fig. For convenience of explanation, the cap 15 shown in Fig. 2 is shown reversely in the vertical direction.

The cap 15 is integrally formed by using various known resin materials such as polycarbonate (PC), polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP). 3 (b), the cap 15 functions as a channel 159 for the nutrient of the bag 100 when the nutrient is administered. However, when the nutrient is administered, Is sealed by the sealing portion 155. [

The cap 15 has a basic structure of the cap main body part 150, and the connection parts 1550a to 1550c and the sealing part 155 are arranged on the cap body part 150. [

The cap body portion 150 has a cap base portion 151 of a substantially cylindrical shape. The step portion 152 of the cap base 151 is formed with a step portion 162 and a protruding portion 160 in this order.

The step portion 162 is a cylindrical body smaller in diameter than the cap base portion 151. A pair of engagement pawls 153, 154 protrude from the side surface near the upper edge of the step portion 162.

Each of the engaging pawls 153 and 154 is a plate-shaped body having a main surface parallel to the ceiling surface 152. A ceiling surface 152 is formed on the main surface of the ceiling surface 152, The convex portions 1531 and 1541 (1541 is not shown in the drawing) are formed so as to protrude.

The ceiling surface of the stepped portion 162 functions as a contact surface 161 for contacting the contact surface 200 of the nozzle 20.

The projection 160 protrudes from the center of the contact surface 161 in a truncated conical shape. The shape of the circumferential surface of the projecting portion 160 is formed to match the shape of the inner circumferential surface of the nozzle body portion 21 so that liquid is leaked from the cap 15 and the nozzle 20 at the contact portion of the projecting portion 160 So that they can be brought into contact with each other.

The sealing portion 155 has a configuration in which the three ribs 155a to 155c are formed so as to be radially erected so that one end of each of the ribs 155a to 155c abuts against each other on the axis of the protruding portion 160 and forms an angle of 120 degrees with respect to each other do. As shown in Fig. 3 (b), the sealing portion 155 has a connecting portion (a thin portion) formed to be thinner than the member thickness of the cap main body portion 150 below the ribs 155a to 155c, (The upper surface of the protruding portion 160) of the cap main body portion 150 by the protruding portions 1550a to 1550c (1550b and 1550c are not shown in the drawing). Slits 156a to 156c having a rectangular cross-sectional shape communicating with the flow path 159 are formed immediately below the ribs 155a to 155c (see Fig. 6 (b)).

An opening 158 communicating with the flow path 159 is formed in the cap 15 and a screw 157 used for connection with the port 101 is formed.

The cap 15 is not limited to a method of fixing the cap 15 to the port 101 side using a screw 157. [ For example, the cap 15 may be thermally welded to the port 101, or both may be connected by a method other than a screw. In this case, of course, the screw 157 is unnecessary.

Further, the cap 15 and the port 101 do not have to be separate, but may be integrally formed.

(Nozzle 20)

The nozzle 20 is integrally formed of the same resin material as the cap 15. As shown in Fig. 2, on the outer surface of the axial main body portion 21, which is machined into a tapered shape, a pair of plate- (205, 206) are formed. As described above, the inner circumferential surface of the nozzle body portion 21 has a shape fitting with the outer circumferential surface of the protruding portion 160. The liquid-receiving tube 30 extends from the distal end portion 2033 (lower end in Fig. 2) of the nozzle body portion 21. As shown in Fig. On the upper end of the nozzle body portion 21 on the upstream side in the liquid flow direction, a plate-like nozzle base portion 22 is arranged so that its main surfaces are perpendicular to the axis of the nozzle 20. 2) of the nozzle base 22 functions as a contact surface 200 to be brought into contact with the contact surface 161 of the cap 15. As shown in Fig.

4 (a) is an external view showing the structure of the nozzle 20 viewed from the contact surface 200 side. 4B is a cross-sectional view showing the internal configuration of the nozzle 20 (a cross-sectional view passing through the engaging groove 2030b and having an angle of 180 degrees around the axis of the nozzle body portion 21). 5 (a), 5 (b) and 5 (c) are views showing the joining process of the engagement pawl 153 and the engagement flange 202 viewed from the axial center side of the cap 15 Represents a continuous portion with the step portion 160 in cross section).

4A, the nozzle base portion 22 has a disk body having an opening portion 2031 communicating with the nozzle body portion 21 at the center thereof, and the center of the nozzle body portion 21 And the circumferential portion protrudes outward with the axis of symmetry. A pair of engaging flanges 201 and 202 engageable with a pair of engaging pawls 153 and 154 of the cap 15 is formed in each of the projecting circumferential portions.

The coupling flanges 201 and 202 are constituted by flange bodies 2012 and 2022, lid portions 2013 and 2023 and coupling pole contact portions 2011 and 2021 as shown in Fig. 5A.

The flange bodies 2012 and 2022 are ribs formed upright along the rim of the contact surface 200.

The lid portions 2013 and 2023 are provided on the contact surfaces 201 and 2022 along the sides of the flange bodies 2012 and 2022 to allow insertion of the engagement pawls 153 and 154 between the flange bodies 2012 and 2022 and the contact surface 200 200 at a required height.

The engaging pawl contact portions 2011 and 2021 are prismatic cylinders which are arranged so as to protrude from the flange bodies 2012 and 2022 toward the axial center of the nozzle 20 while being continuous with the lid portions 2013 and 2023.

The concave portions 2014 and 2024 (2014) are arranged in a continuous relation to each other by cutting the lid portions 2013 and 2023 in the thickness direction in the continuous portions of the engagement portions 2011 and 2021 and the lid portions 2013 and 2023 (Not shown in the figure). The concave portions 2014 and 2024 are the portions that receive and engage the convex portions 1531 and 1541 of the engaging pawls 153 and 154, respectively.

Openings 2010 and 2020 are formed in a portion of the contact surface 200 directly under the lids 2013 and 2023 for the sake of the mold used when molding the nozzle 20 into a resin.

The display surface 204 touching the back surface of the contact surface 200 is provided with an arrow mark indicating " stop " and an arrow indicating the rotational direction so that the operator can accurately recognize the direction in which the nozzle 20 is locked to the cap 15. [ Is displayed. Naturally, the content displayed on the display surface 204 is not limited to this description, and the display may be omitted.

On the other hand, as shown in Figs. 4 (a) and 4 (b), the inner wall of the nozzle body portion 21 is cut in the thickness direction in the vicinity of the opening portion 2031 to form three engagement grooves 2030a to 2030c (At intervals of 120 degrees around the axis of the nozzle body 21). The engaging grooves 2030a to 2030c are means for engaging the ribs 155a to 155c of the cap 15 with each other.

The engaging stepped portion 2032 is formed between the opening portion 2031 and the distal end portion 2033 of the nozzle body portion 21 by narrowing the inner diameter toward the distal end portion 2033 in a stepped shape. The coupling stepped portion 2032 connects the end portion of the liquid receiving tube 30 so as not to fall off.

(Effect on administration)

The procedure for administering the nutrient to the patient using the nutritional administration set (1) having the above-described structure will be described.

First, an operator such as a doctor or nurse puts one end of the bag 100 on a stand as shown in Fig. 1, and directs the port 101 together with the cap 15 downward. Meanwhile, one end of the liquid-receiving tube 30 is passed through the nozzle 20, and the end of the liquid-receiving tube 30 is joined to the coupling stepped portion 2032 inside the nozzle body portion 21 and extended from the distal end portion 2033. Alternatively, the nozzle 20 and the liquid-receiving tube 30 may be connected in advance before the manufacturing step or shipping.

On the other hand, the insertion portion (33) formed on the other end side of the transfusion tube (30) is connected to the tip end of a predetermined tube provided on the patient side.

Next, the operator grips the nozzle 20 with the contact surface 200 facing upward, as shown in Fig. 2, and moves the nozzle 20 so that the engagement flanges 201 and 202 do not interfere with the engagement pawls 153 and 154, The contact surface 200 of the nozzle 20 is brought into contact with the contact surface 161 of the cap 15 (refer to the first direction indicated by the arrow in the vertical direction in FIG. 2) while paying attention to the angle around the axis of the nozzle 20. In this way, the operator relatively moves and brings the nozzle 20 and the cap 15 into contact with each other. At this time, the projecting portion 160 and the sealing portion 155 (ribs 155a to 155c) of the cap 15 are inserted into the nozzle body portion 21.

The outer circumferential surface of the protruding portion 160 is brought into contact with the inner surface of the nozzle body portion 21 in a state in which the liquid does not leak so that the protruding portion 160 of the cap 15, The sealing portion 155 is cut off from the outside air, and the connection state of the nozzle 20 and the cap 15 is formed.

Next, the operator grips the operating portions 205 and 206 with fingers to move the nozzle 20 along the axial center of the nozzle 20 in order to lock (lock) the connection state between the nozzle 20 and the cap 15. [ And rotates to an angle of 60 degrees relative to the cap 15 (see the second direction indicated by the curved arrow in Fig. 2). At this time, the outer circumferential surface of the protrusion 160 and the inner circumferential surface of the nozzle body portion 21 slide relative to each other while keeping the liquid-tight state, and rotate relatively about the axial center of the nozzle 20. The engaging pawls 153 and 154 which were located on the upstream side of the lid portions 2013 and 2023 in the rotating direction before the rotation operation (see FIG. 5A) 2013 and 2023 and advances while pushing up the cover portions 2013 and 2023 in the direction away from the contact surface 200 (see the respective arrows in FIG. 5 (b)). Then, the engaging pawls 153 and 154 finally come into contact with the engaging pawl abutting portions 2011 and 2021 and their progress is prevented. At this time, the convex portions 1531 and 1541 of the coupling pawls 153 and 154 engage with the concave portions 2014 and 2024 formed in the lid portions 2013 and 2023 (FIG. 5C). By this coupling, the coupling (locking) operation of the nozzle 20 and the cap 15 is completed.

After the completion of the locking operation, the nozzle 20 and the cap 15 are firmly engaged with each other in the connected state, so that they do not easily escape.

6 (a) shows the relationship between the positions of the nozzles 20 and the caps 15 and the relationship between the positions of the ribs 155a to 155c (the sealing portion 155) before the lock state and FIG. 6 And Fig. In this figure, the nozzle 20 is shown as a cross-sectional structure that is cut by a line passing through the engaging recesses 2030b and 2030c and passing an angle of 120 degrees around the axis of the nozzle body portion 21. [ 7A and 7B illustrate the positional relationship between the nozzle 20 and the cap 15 in the locked state before and after the lock state by descending down the central axis of the nozzle 20 from the nozzle tip end 2033 FIG. 7 (a) and (b), the outline of the engagement flanges 201 and 202 is shown by a dotted line.

As shown in FIG. 2, immediately after the nozzle 20 is connected to the cap 15, the ribs 155a to 155c are coupled to the coupling grooves 2030a to 2030c only in the nozzle body portion 21 (See Figs. 6 (a) and 7 (a)). In this state, in order for the operator to operate the operating portions 205 and 206 and to perform the above-described locking operation, the nozzle 20 is rotated with respect to the cap 15 with the axis of the nozzle body portion 21 as a rotation axis, The ribs 155a to 155c are coupled to the engaging grooves 2030a to 2030c together with the nozzle 20 to a position deviating from the original position by 60 degrees around the rotation axis Thereby rotating and moving. With this rotational movement, the connecting portions 1550a to 1550c at the lower portions of the ribs 155a to 155c are pushed and broken. And the slits 156a to 156c appear to face the inside of the nozzle body portion 21 (Figs. 6 (b) and 7 (b)). 6 (b), the ribs 155a to 155c are rotated to an angle deviated by 60 degrees from the original position and the connecting portions 1550a to 1550c are broken As a result, the cap 15 in which the slits 156a to 156c are shown is shown in the figure.

As described above, the ribs 155a to 155c rotate according to the locking operation, and the connecting portions 1550a to 1550c are broken, so that the flow path 159 communicates with the nozzle 20 side through the slits 156a to 156c . The liquid-tight state between the outer peripheral surface of the projecting portion 160 and the inner peripheral surface of the nozzle body portion 21 is maintained. 1, the bag 100 is hooked downward on the cap 15, so that the nutrient in the bag 100 flows on the inside of the cap 15 and the nozzle body 21 by its own weight, And can be administered to the patient through the tube 30. Thus, in the nutrient administration set 1, since the administration of the nutrient can be started with the completion of the locking operation of the nozzle 20 and the cap 15, the internal sealing of the bag 100 by the cap 15 is released Even when the nutrients are always blocked from the outside air. Therefore, when a nutritional agent is administered to a patient, impurities are prevented from being mixed into the nutrients from the outside air through the slits 156a to 156c, which is very effective in sanitary management. The nutrient administration set 1 has a structure in which after the nozzle 20 and the cap 15 are connected and the nozzle 20 and the cap 15 are connected to each other, The sealing of the cap 15 can be released at the same time as the locking of the cap 15 is completed.

The nozzle 20 and the cap 15 are a combination of a dedicated one and the other, and each of the engaging portions (here, the engaging pawls 153 and 154 and the engaging flanges 201 and 202, the sealing portion 155, (2030a to 2030c), it is possible to connect and lock normally. This precise connection selectivity is required, so that even if the operator mistakenly tries to connect the cap 15 to a separate liquid line disposed in the patient, the connection can not be made, so that the problem of erroneous connection can be reliably prevented. The nutritional administration set (1) can exhibit high safety even in this regard.

In the cap 15, the connecting portions 1550a to 1550c may be completely broken and the sealing portion 155 may be separated by the rotation of the nozzle 20. However, the ribs 155a to 155c may be formed in the coupling grooves 2030a- 2030c, the sealing portion 155 separated from the cap 15 does not flow to the side of the liquid-receiving tube 30. As shown in Fig.

Further, as for the coupling operation of the nozzle 20 and the cap 15 and the opening operation of the flow path 159, the nozzle 20 and the cap 15 may be moved relative to each other. Therefore, either the cap 15 may be moved relative to the nozzle 20, or the nozzle 20 may be moved relative to the cap 15.

Hereinafter, another embodiment of the present invention will be described focusing on the difference from the first embodiment.

≪ Embodiment 2 >

8 shows Embodiment 2 in which the nozzle 20A side is a mail connector and the cap 15A side is a mail connector. Although the nozzle 20A is shown above and the cap 15A is shown below for convenience of explanation in Fig. 8, the upper and lower relationship of arrangement of the two is reversed as shown in Figs.

The cap 15A is different from Embodiment 1 in that the cylindrical portion 163 is formed so as to surround the periphery of the contact surface 161A with the upper surface of the cylindrical cap base 151A as the contact surface 161A . The inner diameter of the tubular portion 163 is matched with the outer diameter of the main body portion 21A of the nozzle 20A so that the main body portion 21A of the nozzle 20A is inserted into the tubular portion 163 )do. A pair of engaging pawls 153A and 154A having the same structure as that of the engaging portions 153 and 154 are formed around the opening 164 of the tubular portion 163. The same sealing portion 155A as that of 155 is formed at the center of the contact surface 161A with the same connection portion as that of 1550a to 1550c interposed therebetween and is provided immediately below each of the ribs 155a to 155c A slit is formed. The flow path and the slit have the same configurations as those of 159 and 156a to 156c, respectively.

On the other hand, the nozzle 20A is composed of a main body portion 21A and a pair of coupling flanges 201A and 202A.

The main body portion 21A is a cylindrical body and a contact surface 200A which is in contact with the contact surface 161A of the cap 15A is arranged on the lower surface thereof and a display surface 204A is arranged on the upper surface thereof.

The same letter and arrow as 204 are displayed on the surface of the display surface 204A, and the liquid-receiving tube 30 is connected to the center thereof.

The engagement flanges 201A and 202A are of the same mechanism as the engagement flanges 201 and 202 and are configured to be engageable with the engagement pawls 153A and 154A and are formed at equal intervals on the side surface of the body portion 21A. In the configuration shown in Fig. 8, the constituent elements of the coupling flanges 201A and 202A are covered by the box-shaped frame and are not seen from the outside.

In the configuration shown in Fig. 8, a circumferential rib (cylindrical portion) surrounding the periphery of the display surface 204A is formed upright, but this is not essential.

At the center of the contact surface 200A is formed a radial engagement groove 2030A having a shape that can be engaged with the ribs 155a to 155c of the sealing portion 155A.

The body portion 21A is formed with a total of three nozzle holes L1, L2 and L3 so as to pass through the contact surface 200A and the display surface 204A along the axial direction of the cylinder. The nozzle holes L1, L2 and L3 are formed such that the openings on the side of the contact surface 200A close the nozzle 20A to the cap 15A, And the openings on the side of the display surface 204A are formed so as to communicate with the inside of the liquid-receiving tube 30.

Although the nozzle holes L1, L2, and L3 have a circular cross-sectional shape here, the nozzle holes L1, L2, and L3 may have a rectangular cross-sectional shape or may be adjusted by increasing the number of holes in the nozzle.

Even when the cap 15A and the nozzle 20A having the above-described configuration are used, various effects almost identical to those of the nutrient administration set 1 can be obtained.

That is, when the operator connects the nozzle 20A to the cap 15A, care must be taken to prevent the engagement pawls 153A and 154A and the engagement flanges 201A and 202A from interfering with each other and the main body 21A of the nozzle 20A, Shaped portion 163 of the cap 15A. The sealing portion 155A is engaged with the engaging groove 2030A and the nozzle body portion 21A is completely press-fitted into the tubular portion 163 until the contact surfaces 200A and 161A contact each other.

By this operation, the side surface of the nozzle body portion 21A is in contact with the inner surface of the tubular portion 163 without leakage, and the connection between the nozzle 20A and the cap 15A is established.

The operator continuously rotates the nozzle 20A to an angle of 60 degrees about the axis of the nozzle 20A while keeping the connection state and the engaging pawls 153A and 154A are engaged with the engaging flanges 201A and 202A To perform a lock operation. According to this locking operation, the sealing portion 155A coupled to the engaging portion 2030A rotates and the connecting portion is broken, so that the slit comes in contact with the nozzle holes L1 to L3. Accordingly, the nutrient in the bag 100 can flow to the side of the liquid tube 30 through the nozzle holes L1 to L3.

According to the above-described operation, also in Embodiment 2, when used in the same manner as Embodiment 1, the nutrient in the bag 100 does not come into contact with the outside air and the sealing of the cap 15A can be released, So that the nutrient can be administered to the patient in a hygienic manner. Also, since the sealing of the cap 15A is always carried out with the cap 15A connected to the nozzle 20A, it is also possible to prevent the nut 15 from leaking out of the slit or the like of the cap 15A. Further, in the second embodiment, since the cap 15A and the nozzle 20A have a precise connection selectivity with respect to each other in structure, the effect of reliably preventing the problem of mis-connecting the cap 15A to the other liquid-receiving tube is also exhibited.

8 shows a structure in which the engaging groove 2030A and the nozzle holes L1 to L3 are formed in the nozzle 20A. However, like the nozzle 20 of the first embodiment, A cylindrical space (flow path) communicating with the liquid-receiving tube 30 may be formed in the inner wall of the cylindrical body, and coupling grooves 2030a to 2030c may be formed in the cylindrical inner wall to be engageable with the ribs 155a to 155c.

<Other matters>

In the first embodiment, the sealing portion 155 formed by radially combining the three ribs 155a to 155c is shown. However, the number of the ribs formed in the radial direction is not limited to this, and one or two ribs may be used It may be four or more.

Instead of forming the ribs, a rod (columnar body) having a constant length in a direction parallel to the axial center of the nozzle is formed in a standing manner, a connecting portion made of a thinner portion is formed around the lower portion of the rod, A hole corresponding to the slit may be formed immediately below the hole. In this case, the nozzle is provided with a recess in which a rod can be inserted instead of the engagement groove, and each rod is bent at the lower portion according to the lock operation, and the seal of the cap is released by showing a slit (hole). Alternatively, a combination of a sealing portion having a simple three-dimensional shape (rectangular parallelepiped shape, polygonal shape, etc.) and a coupling groove engageable with the sealing portion may be used. It should be noted that the liquid-tight state is maintained even after one of the nozzles is connected to the cap, and the inside of the nozzle body portion in which the flow path is opened should not contact the outside air.

In order to improve the liquid tightness between the cap and the nozzle, a sealing member such as a packing may be provided on any one of the contact surface of the cap and the peripheral surface of the projection. Also, a surface treatment may be performed to flatten the mutual contact surface of the cap and the nozzle.

Further, with respect to the cap, it is possible to prevent the flow path and the outside air from coming into contact with each other when the flow path is opened even if a sealing portion is formed directly on the contact surface without forming a projection on the contact surface. However, in order to secure excellent liquid-tightness between the cap and the nozzle even before the lock, it is preferable to form the protrusion and increase the liquid-tight contact area of the cap and the nozzle. Therefore, it is preferable that the tubular portion and the nozzle body come into contact with each other without leakage, as in the second embodiment.

Further, the nozzle and the cap are not limited to the structure in which they are coupled by the engagement pawl and the engagement flange, but other engagement means may be used. For example, the cap and the nozzle may be coupled by screwing.

The connector set of the medical container of the present invention is most effective when both the male connector and the female connector manufactured as the exclusive combination such as the illustrated caps 15 and 15A and the nozzles 20 and 20A are used together Effect. However, even when the caps 15 and 5A are mounted on the bag 100 as a single body, the use of the sealing portions 155 and 55A can prevent the nozzles 20 and 20A from being locked And has a great advantage in that it can exhibit sealing property.

INDUSTRIAL APPLICABILITY The present invention has excellent usability, for example, it can be widely applied to a case where a liquid material stored in a medical container is administered to a patient by using a tube in an oral nutritional therapy.
