  • FIG. 1 is a partial perspective view showing a schematic configuration of an example of a nutritional supplement container according to the present embodiment.
  • a nutritional supplement container 10 includes a bottle unit 11 as the main container unit, a liquid substance (not shown) containing a nutritional supplement and filled in the bottle unit 11, and a cap 13 mounted to the mouth part 12 (see FIG. 2 ) of the bottle unit 11.
  • a hanger (not shown) for hanging the bottle unit 11 on a stand or the like is provided.

  • a thin film 16 is attached for blocking the opening of the mouth part 12, thereby sealing the interior of the bottle unit 11 with the thin film 16.
  • Examples of the material of the thin film 16 include an aluminum foil, a laminated film formed of paper and an aluminum foil, a resin film containing the same resin as that of the bottle unit 11, and the like.
  • the resin film may be a monolayer or a laminate formed of a plurality of layers.
  • a resin film containing the same resin as that of the bottle unit 11 is used preferably for the surface in contact with the bottle unit 11, from the viewpoint of ensuring high adhesion of the thin film 16 to the bottle unit 11 by thermal welding.
  • the thin film 16 may be adhered to an opening end surface 12f of the mouth part 12, and the rim part 16a may be adhered to the outer peripheral surface in the vicinity of the opening end surface 12f of the mouth part 12. Alternatively, the thin film 16 may be adhered only to the opening end surface 12f of the mouth part 12.
  • the method of adhering the thin film 16 to the mouth part 12 is selected suitably in accordance with the material of the thin film 16, the material of the mouth part 12 and the like.
  • the cap 13 includes a base part 23, a connection part 21 and a hollow nozzle 22 (see FIG. 3 ).
  • the base part 23 denotes a part to be attached to the mouth part 12 of the bottle unit 11.
  • a through hole 22b of the hollow nozzle 22 is in communication with a below-mentioned through hole 212 (see FIG. 4 ) of a tubular part 21a of a base part 23.
  • the base part 23 includes a top plate part 17 and a side wall part 18. When the cap 13 is mounted to the mouth part 12, the top plate 17 faces the opening of the mouth part 12 so as to block the opening while the side wall part 18 surrounds the outer peripheral surface of the mouth part 12.
  • the side wall part 18 includes a small-diameter cylindrical part 18a and a large-diameter cylindrical part 18b.
  • a female thread 19 to be engaged with the male thread 12c is formed on the inner peripheral surface of the small-diameter cylindrical part 18a.

  • the seat part 21b protrudes from the outer main surface of the top plate part 17, while the upper surface is positioned lower than the distal end surface of the tubular part 21a (i.e., the upper surface is positioned closer to the outer main surface of the top plate part 17).
  • the other surface of the claw part 21c, which is opposite to the top plate part 17, is in the same plane as the upper surface of the seat part 21b.
  • the distal outer peripheral surface of the tubular part 21a includes a tapered surface 211 that increases its diameter from the distal end of the tubular part 21a toward the base part side.
  • a rib 213 for partitioning the through hole 212 is provided, and the through hole 212 is partitioned into four by the rib 213. Namely, at the position where the rib 213 is formed, the through hole 212 is divided into four small holes 214.
  • FIG. 5 shows a state where a liquid delivery path 27 that includes a connector 25 and a flexible tube 26 connected to the connector 25 is about to be connected to the connection part 21.
  • FIG. 6 shows a state where the liquid delivery path 27 is connected to the connection part 21.
  • the connection part 21 is configured to be connected to the liquid delivery path 27 including the connector 25.
  • This configuration is helpful for solving the problem of an improper connection as specified below. That is, if a liquid delivery path for an intravenous nutritional treatment was configured to deliver a liquid substance into a body by simply pricking a sharp-tipped connection needle into a connection object, the delivery path could be connected by mistake to a nutritional supplement container 10 to be used for a transintestine nutritional treatment. Furthermore, when the connection part 21 has the rib 213 to partition the through hole of the tubular part 21a as shown in FIG. 4 , the above-mentioned problem of an improper connection can be avoided with further certainty.
  • connection between the connection part 21 and the connector 25 can be achieved by any of known various connection mechanisms such as screwing, fitting, engagement and the like, and it is not limited to the example as shown in FIGs. 5 and 6 .
  • vent filter 28 (see FIG. 3 ) is attached to the inner main surface of the top plate part 17 so as to cover the vent holes 29.
  • the vent filter 28 is surrounded with an annular wall 28a provided on the inner main surface of the top plate part 17.
  • the vent filter 28 is a hydrophobic vent filter, which transmits a gas but not a liquid.
  • a bottle unit 11 formed of a hard material rarely will be deformed.
  • air will be drawn into the bottle unit 11 through the vent filter 28.
  • the liquid substance can flow out continuously from the bottle unit 11 without formation of a hole, for example for ventilation, in the bottle unit 11 by pricking the bottle unit 11 with a needle or the like.
  • the vent filter 28 is not limited particularly in the materials or the like as long as it is a known hydrophobic filter used for a connection needle such as a bottle needle.
  • FIGs. 7B and 9B for the convenience in illustration, the thin film 16 attached to the mouth part 12 of the bottle unit 11 so as to seal the interior of the bottle unit 11 is not shown.
  • FIGs. 7B , 9B and 10B the connection part 21, the hollow nozzle 22 and the annular wall 28a surrounding the vent filter 28 are shown (but not as cross-sectional views) even if they cannot be observed visually, for the purpose of indicating their locations.
  • the cap 13 may take a first mounted state and a second mounted state with respect to the mouth part 12.
  • FIGs. 7A and 7B show the cap 13 and the mouth part 12 in the first mounted state. In the first mounted state, the mounted state of the cap 13 with respect to the mouth part 12 is held so that the end surface 22a of the hollow nozzle 22 is not in contact with the thin film.
  • the first mounted state is held in the following manner.
  • the maximal inner diameter R1 of the large-diameter cylindrical part 18b of the cap 13 at which the second protrusions 24 are formed is greater than the maximal outer diameter of the distal cylindrical part 12d of the mouth part 12, and slightly greater than the maximal outer diameter of the proximal cylindrical part 12b at a position closer to the proximal end side (opposite to the distal side) than the position at which the annular first protrusion 12d is formed.
  • the maximal inner diameter R1 is slightly smaller than the maximal outer diameter of the proximal cylindrical part 12b at a position where the annular first protrusion 12d is formed. Therefore, when the mouth part 12 is pushed into the cap 13 without rotating the cap 13, the second protrusions 24 surmount the first protrusion 12d. Thereby, the cap 13 mounted to the mouth part 12 can be prevented from detaching accidentally from the mouth part 12.
  • the female thread 19 formed on the inner peripheral surface of the small-diameter cylindrical part 18a has a shape to be engaged with the male thread 12c formed on the outer peripheral surface of the distal cylindrical part 12a. Therefore, even if the cap 13 is applied with a force to press the inner main surface of the top plate part 17 of the cap 13 toward the opening end surface of the mouth part 12, as shown in FIG. 8 , a surface 191 of the female thread 19 to face the male thread 12c at the screw-starting side collides with a surface 121 of the male thread 12c at the screw-starting side, in a case where the cap 13 is not rotated with respect to the mouth part 12. As a result, the cap 13 is prevented from being further pushed toward the mouth part 12. Therefore, the thin film will not be punctured by the hollow nozzle 22 unless the cap 13 is rotated with respect to the mouth part 12.
  • the first mounted state is held in this manner.
  • the cap 13 may move up and down with respect to the mouth part 12 as long as accidental detachment of the cap 13 from the mouth part 12 can be prevented and the thin film is not punctured by the hollow nozzle 22.
  • the second mounted state is achieved in the following manner.
  • the cap 13 in the first mounted state is rotated in the direction indicated with the arrows in FIGS. 7A and 7B so as to engage the female thread 19 with the male thread 12c.
  • the hollow nozzle 22 which has been located not to be in contact with the thin film, namely, placed outside the mouth part 12, approaches the thin film.
  • the hollow nozzle 22 positioned outside the mouth part 12 enters the mouth part 12, breaking the thin film 16 (see FIG. 2 ).
  • the cap 13 is rotated to its rotational limit so that the second mounted state as shown in FIGs. 9A to 10 is obtained.
  • the small-diameter cylindrical part 18a of the cap faces the distal cylindrical part 12a, while the large-diameter cylindrical part 18b faces the proximal cylindrical part 12b. Since the thin film 16 is broken as shown in FIG. 10 , when the bottle unit 11 is turned so that its mouth part 12 is directed downward, the hollow nozzle 22 and the vent filter 28 will be in contact with the liquid substance.
  • the rotational limit of the cap 13 can be controlled for example by use of the inner main surface of the top plate part 17 of the cap 13. That is, when the opening end surface 12f of the mouth part 12 (see FIG. 2 ) contacts with the inner main surface of the top plate part 17 of the cap 13, the cap 13 cannot be rotated any more. As a result, a further rotation of the cap 13 is prevented.
  • the length of the male thread 12c varies depending on the types of the threads or the like, though it is not limited particularly as long as the thin film 16 can be broken by the hollow nozzle 22 so that both the hollow nozzle 22 and the vent filter 28 can contact with the liquid substance while a part of the thin film 16 will not fall off, and as long as the air-tightness between the cap 13 and the mouth part 12 can be ensured by the engaging of the male thread 12c and the female thread 19.
  • the male thread is a single-screw thread.
  • the type of the thread is not limited to this example, but a multiple-screw thread may be used, and there is no particular limitation on the number of screws.
  • the present embodiment is helpful to solve the problem of an improper connection in which a liquid delivery path to be used for an intravenous nutritional treatment is connected by mistake to a container to be used for a transintestine nutritional treatment.
  • the cap 13 can take both the first mounted state and the second mounted state with respect to the mouth part 12, the liquid substance in the bottle unit 11 can flow out without peeling by hand a part or the whole of the thin film 16, or without making holes in the thin film 16 with a finger for example. Therefore, a liquid substance such as a nutritional supplement can be supplied hygienically in a simple operation.
  • the cap 13 is mounted to the mouth part 12 in the first mounted state, the operator can supply the liquid substance to a patient only by connecting the liquid delivery path 27 to the connection part 21 and subsequently by rotating the cap 13 to its rotational limit.
  • Examples of the material for the cap 13 include polyethylene (PE), polypropylene (PP), polyacetal (POM), polyethylene terephthalate (PET), polycarbonate (PC) and the like.
  • the cap 13 includes further an annular sealer 171 arranged on the inner main surface 17a of the top plate part 17.
  • the sealer 171 is sandwiched between the inner main surface 17a of the top plate part 17 and the opening end surface 12f (see FIG. 2 ) of the mouth part 12, thereby improving the air-tightness between the cap 13 and the mouth part 12. This serves to prevent effectively the liquid substance from leaking out from the gap between the cap 13 and the mouth part 12 during a supply of the liquid substance to a patient.
  • the sealer 171 is hatched in the drawing.
  • the cap in the present embodiment is configured identically to the cap in Embodiment 1 except that the sealer 171 is provided, and the main container unit to which the cap of the present embodiment is mounted is configured identically to the container in Embodiment 1. Due to this reason, the common components are not explained in detail in this embodiment.
  • Examples of the material for the sealer 171 include isoprene rubber, butylene rubber, thermoplastic elastomer and the like.
  • slits 181 may be formed in the large-diameter cylindrical part 18b of the cap 13, from an opening side end 13a of the cap 13 toward the top plate part 17.
  • the operation of pushing the mouth part 12 into the cap 13 so that the second protrusions 24 surmount the first protrusion 12d can be carried out easily.
  • the cap 13 of the present embodiment is configured identically to the cap in Embodiment 1 except that the slits 181 are formed in the large-diameter cylindrical part 18b, and the container to which the cap of the present embodiment is mounted is configured identically to the container in Embodiment 1. Due to this reason, the common components are not explained in detail in this embodiment.
  • FIG. 13 is a partial perspective view showing a schematic configuration of an example of a nutritional supplement container in the present embodiment.
  • a nutritional supplement container 40 includes a bottle unit 41 as the main container unit, a liquid substance (not shown) containing a nutritional supplement and filled in the bottle unit 41, and a cap 43 mounted to the mouth part 42 (see FIG. 14 ) of the bottle unit 41.
  • a hanger (not shown) for hanging the bottle unit 41 on a stand or the like is provided.
  • the bottle unit 41 is formed of a hard material just like the bottle unit 41 in Embodiment 1.
  • FIG. 14 is an exploded perspective view showing a nutritional supplement container as shown in FIG. 13 .
  • a male thread 42c to be engaged with the female thread 49 of the cap 43 is formed on the outer peripheral surface of the mouth part 42 of the bottle unit 41 .
  • the male thread 42c is a four-screw thread and it includes a segment 421c, a segment 422c, a segment 423c and a segment 424c.
  • FIG. 15 is a plan view showing the mouth part 42 from the opening end surface 42f side.
  • the segment 421c, the segment 422c, the segment 423c and the segment 424c are formed so that the male thread 42 will be present at any positions along the circumferential direction of the mouth part 42.
  • the above-mentioned segments may have areas overlapped with the adjacent segments when the mouth part 42 is viewed from its open end side.
  • annular protrusion 44 is formed on the outer peripheral surface at the proximal side of the mouth part 42.
  • a thin film 46 is attached for blocking the opening of the mouth part 42, so that the interior of the bottle unit 41 is sealed with the thin film 46.
  • the material for the thin film 46 may be the same as that of the thin film 16 in Embodiment 1. Adhesion of the thin film 46 to the mouth part 42 can be carried out similarly to the case in Embodiment 1. Its rim part 46a may be adhered to the outer peripheral surface in the vicinity of an opening end surface 42f of the mouth part 42 and to the opening end surface 42f. Alternatively, the thin film 46 may be adhered only to the opening end surface 42f of the mouth part 42.
  • the process for adhering thin film 46 to the mouth part 42 may be the same as that in Embodiment 1.
  • the cap 43 includes a base part 45, a connection part 51 and a hollow nozzle 52 (see FIG. 16 ).
  • the base part 45 is a part to be attached to the mouth part 42 of the bottle unit 41.
  • the base part 45 includes a top plate part 47 and a side wall part 48.
  • a pair of notched parts 48a are formed in the side wall part 48.
  • a female thread 49 that can be engaged with the male thread 42c is formed at the position closer to the top plate part 47 than the position where the notched parts 48a are formed.
  • the female thread 49 also is a four-screw thread.
  • a plurality of third protrusions 54 are formed at the position farther from the top plate part 47 than the position where the female thread 49 is formed.
  • the plural third protrusions 54 are formed, for example, on the inner peripheral surface in the vicinity of the opening end surface 43a of the base part 45, at regular intervals in the circumferential direction.
  • the number of the third protrusions 54 is equal to the number of screws on the male thread 42c. In the example as shown in FIG. 16 , the number is four.
  • the connection part 51 includes a tubular part 51a, a seat part 51b formed on the circumference of the tubular part 51a, and a claw part 51c that protrudes outward from the outer peripheral surface of the seat part 51b, and a rib 513 that partitions a through hole in the tubular part 51a, similarly to the case in Embodiment 1.
  • the seat part 51b protrudes from the outer main surface of the top plate part 47, the upper face is located lower than the distal end surface of the tubular part 51a (i.e., located closer to the outer main surface of the top plate part 47).
  • the opposite surface of the claw part 51c facing the top plate part 47 is in the same plane as the upper surface of the seat part 51b.
  • connection part 51 is identical to that in Embodiment 1, the connection between the connection part 51 and the liquid delivery path is provided similarly to Embodiment 1.
  • the connection part 51 is configured to be connectable to a liquid delivery path including a connector. This configuration is helpful for solving the problem of an improper connection. That is, if a liquid delivery path for an intravenous nutritional treatment was configured to deliver a nutritional supplement into a body by simply pricking a sharp-tipped connection needle into a connection object, the delivery path could be connected by mistake into a nutritional supplement container to be used for a transintestine nutritional treatment.
  • the connection part 51 is provided with a rib 513 to partition the through hole of the tubular part 51a, the above-mentioned problem of an improper connection can be prevented with further certainty.
  • a pair of vent holes 59 penetrating in the thickness direction are formed, and a vent filter 58 (see FIG. 16 ) is attached to the inner main surface of the top plate part 47 so as to cover the vent holes 59.
  • the material of the vent filter 58 may be the same as that of the vent filter 28 in Embodiment 1.
  • FIGs. 17A to 21 the connected state of the cap 43 with respect to the mouth part 42 will be described with reference to FIGs. 17A to 21 .
  • the thin film 46 that is attached to the mouth part 42 of the main container unit 41 so as to seal the main container unit 41 is not shown in FIGs. 17B , 19B and 20B .
  • FIGs. 17B , 19B , 20B , and 21B the connection part 51, the hollow nozzle 52 and the annular wall 58a surrounding the vent filter 58 are shown (but not as cross-sectional views) even if they cannot be observed visually, for the purpose of indicating their locations.
  • the cap 43 may take a first mounted state and a second mounted state with respect to the mouth part 42.
  • FIGs. 17A and 17B show the cap 43 and the mouth part 42 in the first mounted state. In the first mounted state, the mounted state of the cap 43 with respect to the mouth part 42 is held so that the end surface of the hollow nozzle 52 is not in contact with the thin film 46 ( FIG. 14 ).
  • the first mounted state is held in the following manner.
  • the maximal inner diameter of the cap 43 at the position where the third protrusions 54 are formed is slightly smaller than the maximal outer diameter of the mouth part 42 at the position where the male thread 42c is formed.
  • the diameter of the cylinder that includes the inner surface of a portion 48c of the side wall part 48 arranged between adjacent notched parts 48a in the circumferential direction and that includes a central axis 222 of the cap 43 as its central axis (see FIG. 16 ) is slightly larger than the maximal outer diameter of the mouth part 42 at the position where the male thread 42c is formed. Therefore, by pushing the mouth part 42 into the cap 43 without rotating the cap 43, as shown in FIG. 17B , the third protrusions 54 surmount the male thread 42c. Thereby, accidental detachment of the cap 43 from the mouth part 42 can be prevented.
  • the female thread 49 formed on the inner peripheral surface of the side wall part 48 to be closer to the top plate part 47 than the notched parts 48a has a shape to be engaged with the male thread 42c formed on the outer peripheral surface of the mouth part 42. Therefore, even if the cap 43 is applied with a force to press the inner main surface of the top plate part 47 of the cap 43 toward the opening end surface 42f of the mouth part 42, as shown in FIG. 18 , a surface 491 of the female thread 49 to face the male thread 42c at the screw-starting side collides with a surface 421 of the male thread 42c at the screw-starting side, in a case where the cap 43 is not rotated with respect to the mouth part 42. As a result, the cap 43 is prevented from being further pushed toward the mouth part 42. Therefore, the thin film will not be punctured to be broken by the hollow nozzle 52.
  • the first mounted state is held in this manner.
  • FIGs. 19A and 19B are plan views for explaining the mounted state of the cap 43 with respect to the mouth part 42 in a transitional stage from the first mounted state to the second mounted state.
  • the cap 43 is rotated to its rotational limit so that the second mounted state is obtained (see FIGs. 20A, 20B and 21 ). Since the thin film 46 is broken, when the bottle unit 41 is turned so that its mouth part 42 is directed downward, the hollow nozzle 52 and the vent filter 58 will contact with the liquid substance.
  • the rotational limit of the cap 43 can be controlled for example by use of the inner main surface of the top plate part 47 of the cap 43.
  • the annular protrusion 44 may be formed at a predetermined position so that the rotational limit of the cap 43 is controlled by the annular protrusion 44.
  • the lengths of the male thread 42c and the female thread 49 are not limited particularly as long as the thin film 46 can be broken by the hollow nozzle 52 so that both the hollow nozzle 52 and the vent filter 58 contact with the liquid substance while a part of the thin film 46 will not fall off, and as long as the air-tightness between the cap 43 and the mouth part 42 can be ensured by the engaging of the male thread 42c and the female thread 49.
  • the present embodiment is helpful to solve the problem of an improper connection that a liquid delivery path to be used for an intravenous nutritional treatment is connected improperly.
  • a liquid substance such as a nutritional supplement can be supplied hygienically in a simple operation.
  • the operator can supply the liquid substance to a patient only by connecting the liquid delivery path to the connection part 51 and subsequently by rotating the cap 43 to its rotational limit.
  • the cap 43 further includes an annular sealer (not shown) arranged on the inner main surface of the top plate part 47.
  • the male thread is a four-screw thread.
  • the thread is not limited to this example, and it may be a multiple-screw thread other than the four-screw thread.
  • the female thread it may be a single-screw thread in accordance with the male thread, or may be a multiple-screw thread other than the four-screw thread.
  • the connector 25 and the flexible tube 26 are shown only partially for the convenience in illustration.
  • the liquid delivery path to be connected to the cap in any of Embodiments 1-4 may include any further components to be provided to a liquid delivery path to be used for a conventionally-known transintestine nutritional treatment, such as a flow controller for controlling the flow rate of the liquid substance flowing in the flexible tube 26 by pressing the flexible tube 26, an infusion cylinder 25, a connector that can be connected to a nasal tube or the like fixed to a patient, and a cover for the connector.
  • the present invention can provide a cap for a nutritional supplement container suitably used for a transintestine nutritional treatment, and a nutritional supplement container using the cap.
