Description

CAP AND NUTRITIONAL SUPPLEMENT CONTAINER USING SAME}

TECHNICAL FIELD The present invention relates to a cap attached to a bent portion for flowing out a liquid substance filled in a container body portion of a nutrient container, and a nutrient container attached to the container body portion.

Enteral nutrition therapy and intravenous nutrition therapy are known as a method of administering nutrition or drugs to a patient without being oral. In enteral nutrition therapy, a tube (generally referred to as a `` secret tube '') passed through the nasal passages of the patient to the stomach or duodenum or a gastrointestinal tract formed in the stomach of the patient ( Liquids such as nutrients, fluids, or medications (generally called enteral nutrients) are administered via a tube (commonly called a "PEG tube") inserted into a Percutaneous Endoscopic Gastrostomy. In intravenous nutrition therapy, a liquid (generally referred to as "sap") containing a nutrient component such as glucose or a pharmaceutical component is administered through a fluid line (feeding circuit) inserted into a vein of a patient.

22, the schematic block diagram of an example of the enteral nutrition set used for conventional enteral nutrition therapy is shown. The nutrient is filled in the container main body 101 of the nutrient container 100. A thin film (not shown) is attached to the bent portion 102 through which the nutrients of the container body 101 flow out, and the inside of the container body 101 is sealed. When the nutrient is administered into the body, the plastic connecting needle 104 is punctured by a cap 105 attached to the bend to penetrate the thin film. Thereby, the nutrient can be sent into the body through the tube connected to the connecting needle 104.

23, the schematic block diagram of an example of the infusion set used for the conventional vein nutrition therapy is shown. The bag body 111 of the bag 110 is filled with a liquid containing a nutrient component and a pharmaceutical component. When administering a liquid substance in the body, the connecting needle 114 is punctured into the connecting needle port 113. Thereby, liquid substance can be sent in a body through the tube connected to the connection needle 114 (refer patent document 1).

In a preferable example of the cap of the present invention, the bent portion of the container body portion has a tip-side cylindrical portion formed with a male screw on its outer circumferential surface, and a proximal-side cylindrical shape having a larger outer diameter than the tip-side cylindrical portion and having a first protrusion formed on the outer circumferential surface thereof. Contains wealth. On the other hand, the side wall portion of the cap is opposed to the tip-side cylindrical portion in the second mounting state, and has a small diameter cylindrical portion formed with a female thread coupled to the male screw on the inner circumferential surface thereof, and a proximal end cylindrical portion in the second mounting state. It opposes and includes the large diameter cylindrical part in which the 2nd protrusion was formed in the inner peripheral surface. In this case, the first mounting state is obtained by pushing the bend into the cap so that the second protrusion exceeds the first protrusion, and the thin film is drilled through the hollow nozzle while rotating the cap in the first mounting state to engage the female screw with the male screw. The second mounting state is obtained by rotating the cap to its rotation limit.

It is preferable that a slit is formed in the said large diameter cylindrical part toward the ceiling surface part side from the opening side end of a cap. In this case, the operation which pushes a bend in a cap so that a 2nd protrusion may exceed a 1st protrusion is easy to be performed.

In a preferable example of the cap of the present invention, the bent portion of the container body portion is formed with a male screw on the outer circumferential surface thereof. On the other hand, with respect to the cap, a cutout portion is formed in the sidewall portion, and a female screw capable of engaging with a male screw in the second mounting state is formed at a location on the ceiling surface portion side than the cutout portion of the inner peripheral surface of the sidewall portion, The third projection is formed at a location away from the ceiling surface portion rather than at the location where the female screw is formed. Then, the first mounting state is obtained by pushing the bend into the cap so that the third protrusion exceeds the male screw, and the thin cap is drilled through the hollow nozzle while the female screw is engaged with the male screw by rotating the cap of the first mounting state, and the cap is closed. By rotating to the rotation limit, a second mounting state is obtained. In this type of cap, it is easy to confirm that the third protrusion has exceeded the male screw, and it is easy to confirm that the first mounting state is obtained.

In a preferable example of the cap of the present invention, the connecting portion includes a pedestal portion formed around the tubular portion, and a claw that can be engaged with the connector, which projects outwardly from the outer circumferential surface of the pedestal portion. In this type of cap, the releasing of the connector to the tubular portion is reliably prevented.

In a preferable example of the cap of the present invention, the cap member further includes a sealing material disposed on the inner main surface of the ceiling surface portion of the cap. In this type of cap, the airtightness of the cap and the bent portion in the second mounting state can be improved.

In a preferable example of the cap of the present invention, the ceiling surface portion of the cap is provided with a ventilation hole penetrating in the thickness direction, and the ventilation filter is attached to the ceiling surface portion so as to cover the ventilation hole, and when the second mounting state The filter causes inflow of air outside the container body into the container body. In this type of cap, when the container body portion is formed of a hard material, the container does not need to be punctured with a needle or the like in the container body portion to form a hole for ventilation in the container body portion while supplying a nutrient in the body. Outflow of the liquid substance from the main body can be carried out continuously.

In a preferable example of the cap of the present invention, a rib for partitioning the through hole of the tubular portion is provided, and when the tubular portion is viewed from the front end side, the through hole of the tubular portion is divided into at least three by the rib. In this type of cap, since the entry of the connecting needle into the tubular portion is prevented by the ribs, the problem of misconnection can be prevented more reliably.

(Embodiment 1)

Hereinafter, an example of the cap of the present invention and an example of the nutrient container of the present invention using the cap will be described with reference to FIGS. 1 to 10.

1: is a partial perspective view which shows schematic structure of an example of the container for nutritional agents of this embodiment. As shown in FIG. 1, the nutrient container 10 includes a bottle body 11, which is a container body part, a liquid substance (not shown) containing a nutrient contained in the bottle body 11, and a bottle body 11. Cap 13 mounted to a bend 12 (see FIG. 2). At the bottom of the bottle main body 11, a hanging part (not shown) for suspending the bottle main body 11 is provided.

The bottle main body 11 is formed of a hard material, for example. For this reason, an external shape is maintained unless an external force is applied in particular. The bottle main body 11 is obtained by blow molding using a resin material, for example. As a resin material, polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), nylon, etc. are mentioned, for example.

FIG. 2 is an exploded perspective view of the container for nutrients shown in FIG. 1. FIG. The bent part 12 includes the front end side cylindrical part 12a and the base end side cylindrical part 12b in that order from the front end side. On the outer circumferential surface of the tip-side cylindrical portion 12a, a male screw 12c for engaging with the female screw 19 (see FIG. 3) of the cap 13 is formed. The base end side cylindrical part 12b has an outer diameter larger than the front end side cylindrical part 12a. An annular first projection 12d is formed on the outer circumferential surface of the proximal end cylindrical portion 12b.

The thin film 16 is attached to the bevel portion 12 so as to close the opening of the bevel portion 12, and the bottle main body 11 is sealed by the thin film 16. For this reason, even if the bottle main body 11 with the thin film 16 is directed so that the bend 12 faces downward, the liquid substance in the bottle main body 11 does not leak out from the bottle main body 11.

As a material of the thin film 16, an aluminum foil, the laminated film which consists of paper and aluminum foil, the resin film containing resin like resin contained in the bottle main body 11, etc. are mentioned, for example. The resin film may be either a single layer film or a laminated film composed of a plurality of layers. Above all, from the viewpoint of securing high adhesiveness to the bottle body 11 of the thin film 16 by thermal welding, a resin such as resin contained in the bottle body 11 is placed on the surface of the bottle body 11 in contact with the bottle body 11. The resin film to contain is preferable.

Although the thin film 16 may be adhere | attached to the opening end surface 12f of the spherical part 12, and the peripheral part 16a may be adhere | attached on the outer peripheral surface near the opening end surface 12f of the spherical part 12, 16 may be bonded only to the opening end face 12f of the bent portion 12. The bonding method of the thin film 16 to the bent portion 12 is appropriately selected depending on the material of the thin film 16, the material of the bent portion 12, and the like.

As shown in FIG. 2, the cap 13 includes a base 23, a connecting portion 21, and a hollow nozzle 22 (see FIG. 3). The base 23 is a part attached to the bent part 12 of the bottle main body 11. The through-hole 22b of the hollow nozzle 22 communicates with the through-hole 212 (refer FIG. 4) of the tubular part 21a of the base 23 mentioned later. The base 23 is a side wall surrounding the ceiling surface portion 17 facing the opening and the outer circumferential surface of the sphere 12 so as to block the opening of the sphere 12 when the cap 13 is attached to the sphere 12. Part 18 is included.

As shown in FIG. 3, the side wall part 18 contains the small diameter cylindrical part 18a and the large diameter cylindrical part 18b. On the inner circumferential surface of the small-diameter cylindrical portion 18a, a female screw 19 engaged with the male screw 12c is formed. A plurality of second projections 24 are formed on the inner circumferential surface of the large diameter cylindrical portion 18b. The plurality of second protrusions 24 are formed on the inner circumferential surface near the opening end face of the base at equal intervals in the circumferential direction, for example.

As shown in FIG. 2, the connection part 21 has the tubular part 21a which protruded from the outer main surface of the ceiling surface part 17, the pedestal part 21b formed around the tubular part 21a, and the pedestal part ( The claw part 21c which protruded outward from the outer peripheral surface of 21b) is included. The base part 21b protrudes from the outer main surface of the ceiling surface part 17, but the upper surface is lower than the front end surface of the tubular part 21a (close to the outer main surface of the ceiling surface part 17). The surface opposite to the surface on the ceiling surface portion 17 side of the claw portion 21c is coplanar with the upper surface of the pedestal portion 21b.

As shown in FIG. 4, the outer peripheral surface of the front end side of the tubular part 21a includes the taper surface 211 which enlarged the diameter toward the base side from the front end of the tubular part 21a. The lumen of the tubular part 21a is provided with the rib 213 which partitions the through-hole 212, and the through-hole 212 is divided into four by the rib 213. As shown in FIG. That is, in the formation part of the rib 213, the through hole 212 is four small holes 214. As shown in FIG.

In FIG. 5, about the connecting portion 21. The aspect immediately before the liquid supply circuit 27 including the connector 25 and the flexible tube 26 connected to the connector 25 is shown, In FIG. 6, the liquid supply circuit 27 with respect to the connection part 21 is shown. ) Is connected. As shown in FIG. 5 and FIG. 6, the connecting portion 21 has a structure connected to a liquid feeding circuit 27 including the connector 25. For this reason, the liquid feeding circuit for intravenous nutrition therapy which sends a liquid substance to the body by only sticking a sharp connection needle with a sharp tip to the connection object is mistakenly connected to the nutrient container 10 used for enteral nutrition therapy. The problem of connection is solved. In addition, as shown in FIG. 4, when the connection part 21 is provided with the rib 213 which partitions the through-hole of the tubular part 21a, the problem of the said misconnection can be prevented more reliably.

In FIG. 5 and FIG. 6, only a part of the connector 25 side is shown for convenience of illustration in the liquid feeding circuit 27. After the connector 25 is pressed into the tubular portion 21a and the connector 25 is rotated, the claw portion 21c is disposed below the opening 25a formed in the connector 25. In this state, the claw portion 21c and the convex portion (not shown) of the connector 25 disposed on the lower side of the claw portion 21c (near the outer main surface of the ceiling surface portion 17) are engaged. The connector 25 is fixed to the connecting portion 21, and the detachment of the connector 25 is surely prevented. In addition, the connection of the connection part 21 and the connector 25 is performed by various well-known connection structures, such as a coupling structure, a fitting structure, or a engagement structure, and is not limited to the example shown in FIG. 5 and FIG.

The ceiling surface portion 17 is formed with two ventilation holes 29 penetrating in the thickness direction thereof, and the ventilation filter 28 (FIG. 3) is formed on the inner main surface of the ceiling surface portion 17 so as to cover the ventilation holes 29. Is attached). The ventilation filter 28 is surrounded by an annular wall 28a provided on the inner main surface of the ceiling surface portion 17. The vent filter 28 is a hydrophobic vent filter and allows gas to pass but not liquid. As the liquid substance filled in the bottle main body 11 flows out from the spherical part 12, the pressure in the bottle main body 11 becomes low. When the bottle main body 11 is formed with the soft material, the bottle main body 11 deform | transforms with the outflow of a liquid substance, and outflow of a liquid substance continues. However, deformation of the bottle body 11 formed of a hard material is difficult. In this embodiment, the air is sucked into the bottle main body 11 through the ventilation filter 28 with the outflow of the liquid, and the needle is supplied to the bottle main body 11 while the nutrient is being supplied into the body. Even if the back of the bottle main body 11 is not provided with a hole for venting, the liquid can be discharged from the bottle main body 11 continuously.

The ventilation filter 28 is not particularly limited as long as it is a known hydrophobic filter used for a connecting needle such as a needle.

Next, the connection state with respect to the bent part 12 of the cap 13 is demonstrated using FIG. 7A-10. 7B and 9B, for convenience of illustration, the thin film 16 attached to the bent portion 12 of the bottle body 11 and sealing the inside of the bottle body 11 is omitted. In addition, in FIG. 7B, 9B, and 10, the annular wall 28a surrounding the connection part 21, the hollow nozzle 22, and the ventilation filter 28 is not shown in cross section in order to confirm these positions. In addition, it is listed even if it is not actually seen.

The cap 13 can take the 1st attachment state and the 2nd attachment state with respect to the bend 12. 7A and 7B show the cap 13 and the bent portion 12 in the first mounting state. In the first attachment state, the attachment state of the cap 13 to the sphere 12 is maintained at the position where the end face 22a of the hollow nozzle 22 does not contact the thin film.

The maintenance of a 1st attachment state is performed as follows. The maximum inner diameter R1 at the position where the second projection 24 of the large diameter cylindrical portion 18b of the cap 13 is provided is larger than the maximum outer diameter of the tip-side cylindrical portion 12a of the sphere 12. It is larger and slightly larger than the maximum outer diameter at the proximal end (opposite side of the proximal side) than the location where the annular first projection 12d of the proximal end cylindrical portion 12b is formed. However, the maximum inner diameter R1 is slightly smaller than the maximum outer diameter at the position where the annular first projection 12d of the base end cylindrical portion 12b is formed. For this reason, if the bent part 12 is pushed in the cap 13 without rotating the cap 13, the second protrusion 24 will exceed the first protrusion 12d. Thereby, the cap 13 attached to the bend 12 is prevented from coming off the bend 12.

On the other hand, the female screw 19 formed on the inner circumferential surface of the small-diameter cylindrical portion 18a is formed to be engageable with the male screw 12c formed on the outer circumferential surface of the tip-side cylindrical portion 12a. Therefore, if the cap 13 is not rotated with respect to the bend 12, such a force that the inner main surface of the ceiling surface portion 17 of the cap 13 is pressed toward the opening end surface side of the bend 12 is applied to the cap 13. Even if given, as shown in FIG. 8, the surface 191 which faces the male screw 12c at the coupling start side of the female screw 19 faces the female screw 19 at the coupling start side of the male screw 12c. By this collision, the cap 13 is prevented from being pushed further to the bent portion 12 side. Therefore, unless the cap 13 is rotated with respect to the bend 12, the thin film is not penetrated by the hollow nozzle 22.

In this embodiment, the first mounting state is maintained in this manner. In addition, in the 1st mounting state, if the cap 13 does not come out easily from the bend 12 and a thin film is not perforated by the hollow nozzle 22, the cap 13 will be up and down with respect to the bend 12. You may move to.

The maintenance of a 2nd mounting state is comprised as follows. The cap 13 in the first mounting state is rotated in the direction of the arrow shown in FIGS. 7A and 7B to engage the female screw 19 and the male screw 12c. In connection with this, in the 1st mounting state, the position which does not contact a thin film, ie, the hollow nozzle 22 arrange | positioned outside the spherical part 12, becomes close to a thin film, and then the thin film 16 (refer FIG. 2) While entering the hole 12 is entered. Next, by rotating the cap 13 to its rotational limit, a second mounting state as shown in Figs. 9A to 10 is obtained. In the 2nd mounting state, the small diameter cylindrical part 18a of a cap opposes the front end side cylindrical part 12a, and the large diameter cylindrical part 18b opposes the base end side cylindrical part 12b. As shown in FIG. 10, when the thin film 16 is drilled, the bottle body 11 faces the bent portion 12 downward, and the hollow nozzle 22 and the vent filter 28 come into contact with the liquid.

The rotational limit of the cap 13 can be regulated by the inner main surface of the ceiling surface portion 17 of the cap 13, for example. That is, when the opening end face 12f (refer FIG. 2) of the bent part 12 contacts the inner main surface of the ceiling surface part 17 of the cap 13, the cap 13 cannot be rotated, and thus the cap 13 ) Is further prevented from rotating.

In the present embodiment, the length of the male screw 12c varies depending on the type of screw, etc., but both the hollow nozzle 22 and the ventilation filter 28 can be in contact with the liquid, but a part of the thin film 16 is dropped. The thin film 16 can be perforated by the hollow nozzle 22, and the high tightness of the cap 13 and the bent part 12 can be ensured by the combination of the male screw 12c and the female screw 19. There is no restriction in particular if possible. In the example described using the drawings in the present embodiment, the male screw is a single-row screw. However, the type of screw is not limited to this, and may be a multi-threaded screw, and the number of lines is not particularly limited.

In this embodiment, the second mounting state is maintained in this manner.

In this embodiment, not only the problem of the misconnection that the liquid feeding circuit used for intravenous nutrition therapy is connected to be used for enteral nutrition therapy by mistake, but also the cap 13 is the 1st part with respect to the bend 12, Since both the attached state and the second attached state can be taken, part or all of the thin film 16 may be peeled off by hand or a hole may be punctured in the thin film 16 with a finger. It is possible to spill liquids. Therefore, the supply of liquids such as nutrients can be performed hygienically by simple operation. If the cap 13 is attached to the bent portion 12 in the first mounting state at the time of shipment, the operator rotates the cap 13 to the rotational limit after connecting the liquid supply circuit 27 to the connecting portion 21. Only it becomes possible to supply liquid to a patient.

As a material of the cap 13, polyethylene (PE), polypropylene (PP), polyacetal (POM), polyethylene terephthalate (PET), polycarbonate (PC), etc. are mentioned, for example.

(Embodiment 2)

Next, another example of the cap of the present invention and another example of the nutrient container of the present invention using the cap will be described with reference to FIG. 11.

As shown in FIG. 11, it is preferable that the cap 13 further includes an annular sealing material 171 disposed on the inner main surface 17A of the ceiling surface portion 17. When the cap 13 is attached to the bend 12 in the second mounting state, the sealing material 171 is the inner main surface 17A of the ceiling surface part 17 and the opening end face 12f of the bend 12 (Fig. 2), the airtightness of the cap 13 and the bent part 12 can be improved. For this reason, the liquid substance is effectively prevented from leaking out from the gap between the cap 13 and the bent portion 12 while the liquid substance is being supplied to the patient. In addition, the sealing material 171 is hatched for convenience of illustration. Moreover, the cap of this embodiment has the same structure as the cap in Embodiment 1 except having provided the sealing material 171, The structure of the container main body part to which the cap of this embodiment is mounted is also in Embodiment 1 It has the same configuration as the container body portion. Therefore, description of each part is abbreviate | omitted.

Examples of the material of the sealing material 171 include isoprene rubber, butylene rubber, thermoplastic elastomer, and the like.

(Embodiment 3)

Next, another example of the cap of the present invention and another example of the nutrient container of the present invention using the cap will be described with reference to FIG. 12.

As shown in FIG. 12, the slit 181 may be formed in the large diameter cylindrical portion 18b of the cap 13 from the opening side end 13a of the cap 13 toward the ceiling surface portion 17 side. In this case, the operation | movement which pushes the bent part 12 in the cap 13 easily becomes so that the 2nd protrusion 24 may exceed 1st protrusion 12d (refer FIG. 2). In addition, the cap 13 of this embodiment has the same structure as the cap in Embodiment 1 except that the slit 181 is formed in the large diameter cylindrical part 18b, and the cap of this embodiment is attached. The structure of the container main body part used also has the structure similar to the container main body part in Embodiment 1. Therefore, description of each of these parts is omitted.

As shown in FIG. 15, the part 421c, the part 422c, the part 423c, and the part 424c are formed so that the external thread 42 exists in any position of the circumferential direction of the spherical part 42. As shown in FIG. It is. The adjacent portions may have portions overlapping each other when the spherical portion 42 is viewed from its open end side.

As shown in FIG. 14, the annular protrusion 44 is formed in the outer peripheral surface of the base end side of the spherical part 12. As shown in FIG.

The thin film 46 is attached to the opening end of the bent part 42 so as to close the opening of the bent part 42, and the bottle main body 41 is sealed by the thin film 46. The material of the thin film 46 may be the same as the material of the thin film 16 in the first embodiment. The bonding aspect of the thin film 46 to the spherical part 42 can also be performed similarly to the case of Embodiment 1, and the peripheral part 46a has the outer peripheral surface and the opening cross section of the vicinity of the opening end surface 42f of the spherical part 42. It may be adhered to 42f. The thin film 46 may be adhered only to the opening end face 42f of the spherical portion 42. The bonding method of the thin film 46 to the bend portion 42 may also be the same as in the first embodiment.

As shown in FIG. 14, the cap 43 includes a base 45, a connecting portion 51, and a hollow nozzle 52 (see FIG. 16). The base 45 is a part attached to the bent part 42 of the bottle main body 41. The base 45 has a side wall surrounding the ceiling surface portion 47 facing the opening and the outer circumferential surface of the sphere 42 so as to block the opening of the sphere 42 when the cap 43 is attached to the sphere 42. And a portion 48.

As shown in FIG. 16, a pair of cutouts 48a are formed in the side wall portion 48. The female screw 49 which can be engaged with the male screw 42c is formed at the position on the ceiling surface portion 47 side rather than the portion where the cutout portion 48a is formed in the inner circumferential surface of the side wall portion 48. The female thread 49 is also a 4-row screw. On the other hand, the some 3rd protrusion 54 is formed in the position which is far from the ceiling surface part 47 rather than the location where the female screw 49 is formed in the inner peripheral surface of the side wall part 48. As shown in FIG. The plurality of third protrusions 54 are formed on the inner circumferential surface of the vicinity of the opening end face 43a of the base 45 at equal intervals in the circumferential direction, for example. The number of the third projections 54 is the same as that of the male screw 42c, and four in the example shown in FIG.

As shown in FIG. 14, the connection part 51 is the tubular part 51a, the pedestal part 51b formed around the tubular part 51a, and the pedestal part 51b similarly to the case of Embodiment 1. FIG. And a claw portion 51c protruding outward from the outer circumferential surface of the < RTI ID = 0.0 >), < / RTI > The pedestal part 51b protrudes from the outer main surface of the ceiling surface part 47, but its upper surface is lower than the tip end surface of the tubular part 51a (closer to the outer main surface of the ceiling surface part 47). The surface opposite to the surface on the ceiling surface portion 47 side of the claw portion 51c is in the same plane as the upper surface of the pedestal portion 51b.

In this embodiment, since the connection part 51 is the same as that in Embodiment 1, the connection of the connection part 51 and a liquid feeding circuit is the same as that in the case of Embodiment 1. As shown in FIG. That is, the connection part 51 has a structure which the liquid feeding circuit containing a connector can connect. For this reason, also in this embodiment, the liquid feeding circuit used for the intravenous nutrition therapy which sends a nutritional agent in a body only by inserting a sharp connection needle with a sharp tip to a connection object is wrongly connected to the container for nutritional products used for enteral nutrition therapy. The problem of connection is solved. Moreover, since the connection part 51 is provided with the rib 513 which partitions the through-hole of the tubular part 51a, the problem of the said misconnection can be prevented more reliably.

The ceiling surface portion 47 is provided with a pair of ventilation holes 59 penetrating in the thickness direction thereof, and the ventilation filter 58 is formed on the inner main surface of the ceiling surface portion 47 so as to cover the ventilation holes 59. 16) is attached. The material of the ventilation filter 58 should just be the same as the ventilation filter 28 in Embodiment 1. As shown in FIG.

Next, the connection state with respect to the bending part 42 of the cap 43 is demonstrated using FIG. 17A-FIG. In addition, in FIG. 17B, FIG. 19B, and FIG. 20B, the thin film 46 attached to the bent part 42 of the container main-body part 41 and sealing the inside of the container main-body part 41 is abbreviate | omitted for convenience of illustration. In addition, in FIGS. 17B, 19B, 20B, and 21, the annular wall 58a surrounding the connecting portion 51, the hollow nozzle 52, and the ventilation filter is not shown in cross section in order to confirm these positions. In addition, it describes even if it is not actually seen.

The cap 43 can take the 1st attachment state and the 2nd attachment state with respect to the bend part 42. 17A and 17B show the cap 43 and the bent portion 42 in the first mounting state. In the first attachment state, the attachment state of the cap 43 to the sphere 42 is maintained at the position where the cross section of the hollow nozzle 52 does not contact the thin film 46 (FIG. 14).

The maintenance of a 1st mounting state is as follows. The maximum internal diameter at the location where the third projection 54 of the cap 43 is formed is slightly smaller than the maximum external diameter at the location where the external thread 42c of the bend 42 is formed. However, the diameter of the cylinder which includes the inner surface of the part 48c of the side wall part 48 arrange | positioned between the notch 48a which adjoins in the circumferential direction, and has the center axis 222 of the cap 43 as a center axis. (See FIG. 16) is slightly larger than the maximum outer diameter at the position where the male screw 42c of the bend portion 42 is formed. For this reason, as shown in FIG. 17B, the 3rd protrusion 54 exceeds the external thread 42c as the part 42 pushes in the cap 43, without rotating the cap 43. FIG. Thereby, the inside of the cap 43 is prevented from falling out from the bend 42.

The female screw 49 is formed on the inner circumferential surface of the ceiling surface portion 47 side rather than the cutout portion 48a of the side wall portion 48, and the female screw 49 is formed to be able to engage with the male screw 42c formed on the outer circumferential surface of the spherical portion 42. . Therefore, even if the cap 43 is not rotated, even if such a force that the inner main surface of the ceiling surface portion 47 of the cap 43 is pressed toward the opening end face 42f side of the sphere 42 is applied to the cap 43, FIG. As shown in 18, the surface 491 facing the male screw 42c at the engagement start side of the female screw 49 collides with the surface 421 facing the female screw 49 at the engagement start side of the male screw 42c. The cap 43 is prevented from being pushed further toward the bent portion 42 side. Therefore, the thin film is prevented from being deflected by the hollow nozzle 52.

In this embodiment, the first mounting state is maintained in this manner.

The maintenance of a 2nd mounting state is comprised as follows. The cap 43 in the first mounting state is rotated in the direction of the arrow shown in Figs. 17A and 17B to engage the female screw 49 and the male screw 42c. In connection with this, in the 1st mounting state, the position which does not contact a thin film, ie, the hollow nozzle 52 arrange | positioned out of the spherical part 42, becomes close to a thin film, and then the bend part 42 is penetrating through a thin film. To enter. 19A and 19B are plan views illustrating a mounting state of the cap 43 of the cap 43 on the way from the first mounting state to the second mounting state. Subsequently, by rotating the cap 43 to its rotational limit, a second mounting state is obtained (see Figs. 20A, 20B, and 21). The hollow nozzle 52 and the ventilation filter 58 come into contact with the liquid when the thin film 46 is opened so that the bottle body 41 faces the bent portion 42 downward.

The rotational limit of the cap 43 can be regulated by, for example, the inner main surface of the ceiling surface portion 47 of the cap 43, but the annular protrusion 44 is formed at a predetermined position to form the annular protrusion 44. ), The rotational limit of the cap 43 may be regulated.

In the present embodiment, the length of the male screw 42c and the female screw 49 is such that both the hollow nozzle 52 and the ventilation filter 58 can come into contact with the liquid, but a part of the thin film 46 does not fall off. As long as the thin film 46 can be penetrated by the hollow nozzle 52 and the high airtightness of the cap 43 and the bent part 42 can be secured by the combination of the male screw 42c and the female screw 49, There is no limit.

In this embodiment, the second mounting state is maintained in this manner.

Also in this embodiment, as in the first embodiment, not only the problem of incorrect connection that the liquid feeding circuit used for intravenous nutrition therapy is connected incorrectly can be solved, but also the supply of liquids such as nutrients can be performed hygienically with a simple operation. Can be. If the cap 43 is attached to the bent portion 42 in the first mounting state at the time of shipment, the operator simply rotates the cap 43 to the rotational limit after connecting the liquid feeding circuit to the connecting portion 51, It is possible to supply liquid to the patient.

Also in this embodiment, for the same reason as Embodiment 1, it is preferable that the cap 43 further includes the annular sealing material (not shown) arrange | positioned on the inner main surface of the ceiling surface part 47.

In addition, in the example demonstrated using drawing in this embodiment, a male screw is a 4-row screw, and the kind of screw is not limited to this, A single-threaded screw may be sufficient, and a multi-line screw other than a 4-row screw may be sufficient. Also about a female thread, a single-threaded screw may be sufficient and a multi-threaded screw other than a 4-threaded screw may be sufficient.

In addition, although the liquid supply circuit 27 shown in FIG. 5 has shown only the part of the connector 25 and the flexible tube 26 for convenience of illustration, the liquid supply circuit connected to the cap in Embodiment 1-4 is , A flow regulator for adjusting the flow rate of the liquid flowing through the flexible tube 26 by pressing the flexible tube 26, a connector that can be connected to a nasal tube fixed to a patient, a cover of the connector, and the like, The component part which the liquid feeding circuit used for conventionally known enteral nutrition therapy may further be included.

In the present invention, a cap of a nutrient container suitable for enteral nutrition therapy, and a nutrient container using the same can be provided.
