Description

[Technical Field]

[0001] The present invention relates to a medical container for storing medical contents such as medicinal liquids. [Background technology]

[0002] As an example of the above-mentioned medical container, a container 901 equipped with a dispensing stopper 902 and an overcap 903, as shown in FIG. 13, is known (Patent Document 1). The dispensing stopper 902 has a tip opening 902a for discharging the contents of the container 901, and a small protrusion 905 is provided at the lower end of the outer peripheral wall of the dispensing stopper 902. The small protrusion 905 is a cantilevered support piece with one end 905a integrally connected to the dispensing stopper 902 and the other end 905b being a free end. As shown in FIG. 14, a protrusion 904 is integrally provided at the lower end of the inner peripheral wall of the overcap 903.

[0003] The small protrusion 905 provides a clicking sensation by riding over the protruding portion 904 of the overcap 903 in the region where the overcap 903 is completely screwed in, and also prevents loosening of the overcap 903. With this configuration, when the protruding portion 904 of the overcap 903 rides over the other end 905b, which is the free end of the small protrusion 905, the other end 905b is easily displaced, so the contact pressure between them is small, and furthermore, after the protruding portion 904 rides over, the other end 905b returns to its original state. Therefore, even if the overcap 903 is repeatedly attached and removed, there is almost no wear, and the clicking sensation and anti-loosening effect are maintained for a long period of time.

[0004] [Patent Document 1] Patent No. 5037889 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional container, in order to form the small protrusions 905 on the dispensing plug 902, the lower end of the outer wall of the dispensing plug 902 had to be made thicker than other parts, which resulted in the dispensing plug 902 becoming larger and the medical container becoming larger, which was an inconvenience.

[0006] Therefore, an object of the present invention is to provide a medical container that can be prevented from becoming large by reducing the wall thickness. [Means for solving the problem]

[0007] The medical container of the present invention comprises a container body including a body portion including a body-side peripheral wall portion formed around an axis and capable of containing contained medical items, and a mouth portion provided on one axial side of the body portion and including an opening for putting in and taking out the contained medical items, and a cap body including a cap-side peripheral wall portion formed around the axis and covering the mouth portion to open and close the opening by rotating about the axis relative to the mouth portion, and at least one of the body-side peripheral wall portion of the body portion of the container body and the cap-side peripheral wall portion of the cap body has a peripheral wall portion extending in a direction from inside to outside the container. A through hole is formed through at least one of the peripheral wall portions, and an elastic portion that elastically deforms inward and outward directions of the container is provided so as to extend from a hole edge portion that defines the through hole in at least one of the peripheral wall portions into the interior of the through hole, and the elastic portion is provided with a one-side locking portion that protrudes inward and outward directions of the container, and a other-side locking portion is provided on the other of the container body and the cap body that abuts against the one-side locking portion as the cap body rotates around the axis, elastically deforming the elastic portion and overcoming the one-side locking portion.

[0008] According to this configuration, a through hole is formed in at least one of the peripheral wall portions of the body-side peripheral wall of the barrel of the container body and the cap-side peripheral wall of the cap body, and a one-side locking portion is provided on the elastic portion located inside the through hole, protruding inward and outward from the container and capable of climbing over the other-side locking portion. By providing the elastic portion on which the one-side locking portion is provided extending into the through hole, it is possible to reduce the thickness of at least one of the peripheral wall portions of the container body and the cap body in which the through hole is formed, and to prevent the medical container from becoming larger in size.

[0009] In the medical container of the present invention, the body portion is provided at a distance inward from the main body side peripheral wall portion and includes a storage portion for storing medical contents, the through hole is formed in the main body side peripheral wall portion, the elastic portion extends from the hole edge of the through hole, the one locking portion protrudes toward the outside of the container relative to the elastic portion, and the other locking portion is provided on the cap body so as to be positioned on the outside of the container of the main body side peripheral wall portion.

[0010] According to this configuration, the body portion has an inner storage portion and an outer main body side peripheral wall portion, and a through hole, an elastic portion, and a one-way locking portion are provided in the main body side peripheral wall portion, so that the through hole, elastic portion, and one-way locking portion can be provided so as not to affect the storage portion that stores the medical contents.

[0011] In the medical container of the present invention, the main body side peripheral wall portion may include a guard portion that protrudes outward from the container around the through hole.

[0012] According to this configuration, when the medical container is dropped, it is possible to prevent the elastic portion and one locking portion from colliding with other members such as the floor.

[0013] In the medical container of the present invention, the through hole, the elastic portion, and the one engaging portion may be arranged on the other axial side of the other axial end portion of the cap body, and the other engaging portion may protrude from the other axial end portion of the cap body to the other axial side.

[0014] With this configuration, the one locking portion and the other locking portion are positioned on the other axial side of the other end of the cap body, so that the locking status of the one locking portion and the other locking portion is not hidden by the cap body but can be seen and confirmed from the outside.

[0015] In the medical container of the present invention, the through hole is formed in the cap-side peripheral wall portion, the elastic portion is configured so that its outer surface on the outer side of the container is flush with the outer peripheral surface of the cap-side peripheral wall portion on the outer side of the container or is located on the inner side of the container than the outer peripheral surface of the cap-side peripheral wall portion, the one locking portion protrudes inward from the elastic portion and the other locking portion is provided on the body-side peripheral wall portion.

[0016] With this configuration, the cap side peripheral wall portion does not protrude outward from the container from the outer peripheral surface, so that when the medical container is dropped, it is possible to prevent the elastic portion and one-side engaging portion from colliding with other components such as the floor. [Effects of the Invention]

[0017] As described above, according to the present invention, it is possible to provide a medical container that can be prevented from becoming large by reducing the wall thickness. [Brief explanation of the drawings]

[0019] A medical container according to one embodiment of the present invention will be described below with reference to FIGS.

[0020] 1 and 2, a medical container 1 according to this embodiment includes a container body 2 and a cap body 3. This medical container 1 is a vial, but may also be a cartridge, a centrifuge tube, an ampoule, or the like.

[0021] As shown in Fig. 3, the container body 2 comprises a body 21 capable of containing a medical item, and a mouth 22 provided on one axial side of the body 21. The medical item may be a medicinal solution, an injection, a cell-containing liquid, a cell sheet, or the like. The sections 21, 22 of the container body 2 are integrally formed, but these sections 21, 22 may also be formed separately and then combined. The container body 2 is made of a synthetic resin, but may also be made of glass, etc.

[0022] In the medical container 1, the side where the mouth portion 22 of the container body 2 is located, i.e., the upper side in Figures 1 to 4A and 5, is the "one axial side," and the side opposite the side where the mouth portion 22 is located in the axial direction of the container body 2, i.e., the lower side in Figures 1 to 4A and 5, is the "other axial side." Also, the "axial direction" of the medical container 1 is the cylindrical axis direction of the container body 2. Furthermore, the radial direction perpendicular to the axial direction will also be simply referred to as the "radial direction."

[0023] The body portion 21 is, for example, cylindrical (see FIG. 3). The body portion 21 also includes a main body side peripheral wall portion 20 formed around an axis. In this embodiment, the body portion 21 includes, in addition to the main body side peripheral wall portion 20, a storage portion 23 that is provided on the inner side of the container and spaced apart from the main body side peripheral wall portion 20, and that stores the medical contents. The main body side peripheral wall portion 20 includes a main body side tubular portion 200 that is substantially cylindrical.

[0024] As shown in FIG. 4A, the main body side tube portion 200 is, for example, cylindrical. The outer diameter of the main body side tube portion 200 is smaller on the opening portion 22 side. Specifically, the main body side tube portion 200 has a small diameter portion 202 located on one axial side and a large diameter portion 203 extending from the end of the small diameter portion 202 on the other axial side toward the other axial side. The main body side tube portion 200 may have a shape that bulges circumferentially at the center in the axial direction, or a shape with a uniform outer diameter. The main body side tube portion 200 may also have a rectangular cylindrical shape.

[0025] The mouth portion 22 is, for example, substantially cylindrical (see FIG. 3). The mouth portion 22 also includes an opening 220 for putting in and taking out the contained medical item. The outer diameter of the mouth portion 22 is smaller than the outer diameter of the body portion 21. In this embodiment, as shown in FIG. 5, the mouth portion 22 has a first mouth portion fitting portion 221 located on one axial side, and a second mouth portion fitting portion 222 connected to the first mouth portion fitting portion 221 on the other axial side.

[0026] The first mouth fitting portion 221 constitutes the tip portion of the mouth portion 22. The second mouth fitting portion 222 constitutes the central portion and base end portion in the axial direction of the mouth portion 22. The second mouth fitting portion 222 also includes a cylindrical mouth main body portion 223 and a male screw 224 provided on the outer periphery of the mouth main body portion 223. The outer diameter of the second mouth fitting portion 222 is larger than the outer diameter of the first mouth fitting portion 221. The outer diameter of the second mouth fitting portion 222 is also smaller than the outer diameter of the small diameter portion 202 of the body portion 21.

[0027] A through hole 4 is formed in the body-side peripheral wall portion 20 (see FIG. 4A). The through hole 4 penetrates the body-side peripheral wall portion 20 in the container-outward direction. Specifically, the through hole 4 penetrates the body-side peripheral wall portion 20 in the thickness direction of the body-side peripheral wall portion 20, i.e., in the radial direction of the body-side peripheral wall portion 20. In this embodiment, the container-outward direction is a direction perpendicular to the axial direction. The body-side peripheral wall portion 20 also has a guard portion 201 that protrudes outward from the container around the through hole 4.

[0028] The through hole 4 extends in the circumferential direction of the main body side peripheral wall portion 20. The through hole 4 has, for example, a rectangular shape with its longitudinal direction aligned with the circumferential direction. In this embodiment, the through hole 4 is formed at one axial end of the main body side peripheral wall portion 20. Specifically, the through hole 4 is formed in a portion including the boundary between the small diameter portion 202 and the large diameter portion 203 of the main body side cylindrical portion 200. For example, the through hole 4 is formed across the other axial end of the small diameter portion 202 and the one axial end of the large diameter portion 203.

[0029] Two through holes 4 are provided in the main body side peripheral wall portion 20 (see FIG. 4B). The two through holes 4 are arranged at positions sandwiching the axis. Note that one through hole 4 may be provided in the main body side peripheral wall portion 20, or three or more through holes 4 may be provided.

[0030] The hole edge portion 40 is composed of portions 401 and 402 that face each other in the axial direction and portions 403 and 404 that face each other in the circumferential direction (see FIG. 4A). Specifically, the hole edge portion 40 includes a first hole edge portion 401 that extends in the circumferential direction and is located on one axial side, and a second hole edge portion 402 that extends in the circumferential direction and is located on the other axial side. The hole edge portion 40 also includes a third hole edge portion 403 that extends along the axis and is located on the starting side of the rotation direction when the cap body 3 is closed, and a fourth hole edge portion 404 that extends along the axis and is located on the terminal side of the rotation direction when the cap body 3 is closed.

[0031] As shown in FIG. 4B , the guard portion 201 is a long rib extending in the circumferential direction of the main body side tube portion 200. In this embodiment, the guard portion 201 extends from the fourth hole edge portion 404 of one through hole 4 to just before the third hole edge portion 403 of the other through hole 4. Two guard portions 201 are provided on the main body side tube portion 200. The two guard portions 201 are arranged at positions sandwiching the axis. Note that one guard portion 201, or three or more guard portions 201 may be provided on the main body side tube portion 200.

[0032] An elastic portion 5 is provided so as to extend from a hole edge portion 40 that defines the through hole 4 in the main body side peripheral wall portion 20 into the inside of the through hole 4 (see FIG. 4A). In this embodiment, the elastic portion 5 extends from a third hole edge portion 403 into the inside of the through hole 4.

[0033] The elastic portion 5 extends in the circumferential direction of the main body side peripheral wall portion 20 inside the through hole 4. Specifically, the elastic portion 5 extends in the circumferential direction inside the through hole 4 from the third hole edge portion 403 of the main body side peripheral wall portion 20 to just before the fourth hole edge portion 404. The elastic portion 5 is, for example, in the shape of a rectangular plate whose longitudinal direction is along the circumferential direction. The thickness of the elastic portion 5 is approximately uniform at every position.

[0034] An outer surface 500 of the elastic part 5 facing outward from the container is a curved surface (see FIG. 4B). An inner surface 501 of the elastic part 5 facing inward from the container is a curved surface. In this embodiment, a protrusion 502 is provided on the inner surface 501 of the elastic part 5 (see FIG. 5). This protrusion 502 is provided at an end of the inner surface 501 on one axial side. The protrusion 502 allows the elasticity of the elastic part 5 to be adjusted.

[0035] Furthermore, the elastic portion 5 elastically deforms inward and outward directions of the container. The elastic portion 5 is formed, for example, from a synthetic resin. In this embodiment, the elastic portion 5 extends to the central portion in the axial direction of the through-hole 4 (see FIG. 4A). That is, a one-side edge 51 located on one side of the elastic portion 5 in the axial direction is separated from the first hole edge portion 401. A other-side edge 52 located on the other side of the elastic portion 5 in the axial direction is separated from the second hole edge portion 402. Furthermore, an extending edge 53 of the elastic portion 5 is separated from the fourth hole edge portion 404. A base end edge 54 of the elastic portion 5 is continuous with the third hole edge portion 403 in the circumferential direction.

[0036] One elastic portion 5 is provided inside each through-hole 4 (see FIG. 4B). In this embodiment, two elastic portions 5 are provided on the main body side peripheral wall portion 20.

[0037] The elastic part 5 is provided with a one-side locking part 6 that protrudes outward from the container. That is, the one-side locking part 6 protrudes outward from the container relative to the elastic part 5. In this embodiment, the one-side locking part 6 is provided on the extending end part including the extending end edge 53 of the elastic part 5.

[0038] One one-way locking portion 6 is provided on each elastic portion 5. In this embodiment, two one-way locking portions 6 are provided on the main body side peripheral wall portion 20.

[0039] The outer peripheral surface 60 of the first locking portion 6 is a curved surface that is convex outward from the container. Specifically, the outer peripheral surface 60 of the first locking portion 6 is a curved surface such that the central portion in the circumferential direction is the apex 61 that is located furthest outward from the container.

[0040] In addition to the apex 61, the outer peripheral surface 60 includes a closing contact portion 62 located closer to the starting end of the rotation direction when closing the cap body 3 than the apex 61, and an opening contact portion 63 located closer to the terminal end of the rotation direction when closing the cap body 3 than the apex 61. That is, in addition to the apex 61, the outer peripheral surface 60 includes the closing contact portion 62 located closer to the base end edge 54 of the elastic portion 5, and the opening contact portion 63 located closer to the extending end edge 53 of the elastic portion 5. The specific configurations of the contact portions 62 and 63 will be described later.

[0041] In this embodiment, the protruding position of the guard portion 201 of the main body side peripheral wall portion 20 is located further outward from the container than the protruding position of the one locking portion 6. That is, the protruding side edge of the outer circumferential surface 2010 of the guard portion 201 is located further outward from the container than the protruding side edge of the outer circumferential surface 60 of the one locking portion 6. The guard portion 201 is also provided at the same position as the elastic portion 5 in the axial direction (see FIG. 4A). The guard portion 201 is also provided at the same position as the one locking portion 6 in the axial direction. The guard portion 201 may be provided at a different position from the elastic portion 5 in the axial direction.

[0042] The cap body 3 includes a cap-side peripheral wall portion 30 formed around an axis, covers the mouth portion 22, and opens and closes the opening 220 by rotating around the axis relative to the mouth portion 22 (see FIG. 3). In this embodiment, the cap body 3 includes a cap lid portion 31 connected to one side of the cap-side peripheral wall portion 30 in the axial direction. The cap body 3 also includes an inner plug portion 32 provided inside the cap-side peripheral wall portion 30 and the cap lid portion 31.

[0043] The cap-side peripheral wall portion 30 is a portion on whose inner circumferential surface there is provided a female screw that can be threaded onto a male screw 224 provided on the outer periphery of the mouth body portion 223 of the container body 2. The cap-side peripheral wall portion 30 is substantially cylindrical. The outer diameter of this cap-side peripheral wall portion 30 is uniform. Note that the cap-side peripheral wall portion 30 may have a shape that bulges circumferentially in a portion in the axial direction.

[0044] The outer peripheral surface of the cap-side peripheral wall portion 30 is provided with a plurality of axially extending grooves aligned in the circumferential direction. These grooves are provided to prevent the user's hand from slipping when rotating the cap body 3. The grooves extend in the axial direction from one axial edge of the cap-side peripheral wall portion 30 to just before the other axial edge. A female screw is provided on the inner peripheral surface of the cap-side peripheral wall portion 30 (see FIG. 5).

[0045] The cap lid portion 31 closes an opening on one axial side of the cap side peripheral wall portion 30. The cap lid portion 31 is disk-shaped and is formed integrally with the cap side peripheral wall portion 30. The outer peripheral surface of the boundary between the cap lid portion 31 and the cap side peripheral wall portion 30 is a curved surface.

[0046] The inner plug portion 32 is a portion that is attached to the mouth portion 22, and specifically, a portion that fits into the first mouth portion fitting portion 221. In this embodiment, the inner plug portion 32 includes an inner plug closing portion 320 that closes the opening 220 of the mouth portion 22, and an inner plug leg portion 321 that extends from the inner plug closing portion 320. The inner plug portion 32 is separate from the cap side peripheral wall portion 30 and the cap lid portion 31, and is fixed to the cap lid portion 31. Note that the inner plug portion 32 may be formed integrally with the cap side peripheral wall portion 30 or the cap lid portion 31.

[0047] The inner plug closure portion 320 is a portion that abuts against the mouth portion 22 when the cap body 3 is attached to the mouth portion 22. The inner plug closure portion 320 is a disk-shaped portion. In this embodiment, a base end face 3200, which is the end face on the other axial side of the inner plug closure portion 320, abuts against a tip end face 2210, which is the end face on one axial side of the first mouth fitting portion 221 of the mouth portion 22 (see FIG. 5).

[0048] When the cap body 3 is attached to the mouth 22, the inside plug leg portion 321 fits inside the mouth 22. In this embodiment, the inside plug leg portion 321 fits inside the first mouth fitting portion 221. Furthermore, the inside plug leg portion 321 is a cylindrical portion, but it may be a columnar portion or the like.

[0049] The cap body 3 is provided with a second locking portion 7 that abuts against the first locking portion 6 as the cap body 3 rotates about its axis, elastically deforming the elastic portion 5 and climbing over the first locking portion 6 (see FIG. 1 ). The second locking portion 7 is provided on the cap body 3 so as to be positioned on the outer side of the body-side peripheral wall portion 20. Specifically, the second locking portion 7 protrudes from the second end portion 33 of the cap body 3 toward the other side in the axial direction. In this embodiment, when the cap body 3 is closed, the second locking portion 7 is positioned between the second end portion 33 of the cap body 3 and the second hole edge portion 402 of the through-hole 4 of the container body 2 in the axial direction.

[0050] The outer surface 70 of the other locking portion 7 facing the other axial side is a curved surface. The outer surface 70 of the other locking portion 7 may also be a flat surface. The circumferential dimension of the other locking portion 7 is approximately the same as the circumferential dimension of the one locking portion 6, but may be different from the circumferential dimension of the one locking portion 6. The axial dimension of the other locking portion 7 is approximately the same as the axial dimension of the one locking portion 6, but may be different from the axial dimension of the one locking portion 6. The dimension of the other locking portion 7 in the container inner / outer direction is thinner than the thickness of the cap-side peripheral wall portion 30.

[0051] In this embodiment, the other-side locking portion 7 is formed in a substantially rounded rectangular shape when viewed in the radial direction (see FIG. 2 ). Specifically, the other-side locking portion 7 is composed of a first portion 71 constituting an end portion on one axial side, a second portion 72 extending from the first portion 71 to the other axial side in the axial direction, and a third portion 73 constituting an end portion on the other axial side and extending from the second portion 72 to the other axial side in the axial direction. The width of the first portion 71, i.e., the dimension of the first portion 71 in the circumferential direction, decreases toward the other axial side. The width of the second portion 72, i.e., the dimension of the second portion 72 in the circumferential direction, is substantially uniform. The width of the third portion 73, i.e., the dimension of the third portion 73 in the circumferential direction, decreases toward the other axial side.

[0052] Furthermore, the cap body 3 is provided with the same number of other-side locking portions 7 as the one-side locking portions 6. Specifically, two other-side locking portions 7 are provided on the cap body 3. In this embodiment, the two other-side locking portions 7 are arranged at positions sandwiching the axis.

[0053] In this embodiment, when closing the cap body 3, the other locking portion 7 moves from the edge 2012 of one guard part 201 at the start side in the rotation direction when closing the cap body 3 to the edge 2011 of the other guard part 201 at the end side in the rotation direction when closing the cap body 3 (see FIG. 4B). At this time, the other locking portion 7 abuts against the closing abutment portion 62 of the one locking portion 6, pushing the one locking portion 6 toward the inside of the container and climbing over the one locking portion 6. Thereafter, the other locking portion 7 can move in this rotation direction until it abuts against the edge 2011 of the guard part 201 at the end side in the rotation direction when closing the cap body 3. In other words, the edge 2011 of the guard part 201 has the function of preventing the cap body 3 from being closed too far.

[0054] Alternatively, the closing contact portion 62 may be located on the extended end edge 53 side of the elastic portion 5 , and the opening contact portion 63 may be located on the base end edge 54 side of the elastic portion 5 .

[0055] In this medical container 1, when the cap body 3 is attached to the opening 22, the through-hole 4, the elastic portion 5, and the one locking portion 6 are located on the other side of the other end portion 33 in the axial direction of the cap body 3 (see FIG. 1). Therefore, the through-hole 4, the elastic portion 5, and the one locking portion 6 are not hidden by the cap body 3. Furthermore, in this configuration, the other locking portion 7 is also exposed to the outside.

[0056] The following describes how to use the medical container 1. When using the medical container 1, first, a medicinal liquid or the like is placed in the container body 2, and the cap body 3 is attached to the opening 22 of the container body 2. At this time, with the inner plug leg portion 321 of the inner plug portion 32 of the cap body 3 fitted inside the opening 22, the cap body 3 is rotated about its axis to thread the cap body 3 onto the opening 22, so that the other locking portion 7 of the cap body 3 is positioned on the outer side of the container relative to the base end edge 54 of the elastic portion 5 of the container body 2. In this embodiment, the other locking portion 7 passes between the edge 2012 of the guard portion 201 on the starting end side in the rotation direction when closing the cap body 3 and the third hole edge 403 on the body-side peripheral wall portion 20 of the container body 2, and moves until it is positioned on the outer side of the container relative to the base end edge 54 of the elastic portion 5.

[0057] When the cap body 3 is further rotated to close it, the other-side locking portion 7 of the cap body 3 comes into circumferential contact with the closing contact portion 62 of the one-side locking portion 6 of the container body 2. When the cap body 3 is further rotated from this state, the other-side locking portion 7 elastically deforms the elastic portion 5 toward the inside of the container, and as a result, the one-side locking portion 6 provided on the elastic portion 5 also moves toward the inside of the container. That is, the other-side locking portion 7 comes into circumferential contact with the closing contact portion 62 of the one-side locking portion 6, pushing the elastic portion 5 and the one-side locking portion 6 toward the inside of the container. At this time, the elastic portion 5 and the one-side locking portion 6 are energized. As a result, the other-side locking portion 7 passes over the apex 61 of the one-side locking portion 6 and passes the opening contact portion 63, completing the other-side locking portion 7 climbing over the one-side locking portion 6. Furthermore, once the one locking portion 6 has been overcome, the stored energy of the elastic portion 5 and the one locking portion 6 is released, and the positions of the elastic portion 5 and the one locking portion 6 in the container interior / exterior direction return to the positions they were in before being pushed in. In this way, the container body 2 containing a medicinal solution or the like can be closed with the cap body 3.

[0058] When the cap body 3 is opened, the other-side locking portion 7 abuts the opening contact portion 63 of the one-side locking portion 6 from the circumferential direction. Further rotation of the cap body 3 from this state causes the other-side locking portion 7 to abut the opening contact portion 63 of the one-side locking portion 6 from the circumferential direction, pushing the elastic portion 5 and the one-side locking portion 6 toward the inside of the container. At this time, the elastic portion 5 and the one-side locking portion 6 are energized. As a result, the other-side locking portion 7 passes over the apex 61 of the one-side locking portion 6 and the closing contact portion 62, completing the other-side locking portion 7 climbing over the one-side locking portion 6. Furthermore, once the one-side locking portion 6 has climbed over, the energization of the elastic portion 5 and the one-side locking portion 6 is released, and the positions of the elastic portion 5 and the one-side locking portion 6 in the container interior / exterior direction return to their positions before being pushed. In this manner, the cap body 3 can be removed from the container body 2 containing a medicinal solution or the like.

[0059] In the above-described medical container 1, a through hole 4 is formed in at least one of the peripheral wall portions, the body-side peripheral wall portion 20 of the container body 2 and the cap-side peripheral wall portion 30 of the cap body 3, and a one-side locking portion 6 that protrudes outward from the container and can climb over the other-side locking portion 7 is provided in the elastic portion 5 located inside this through hole 4. By thus providing the elastic portion 5 that provides the one-side locking portion 6 to extend into the through hole 4, the thickness of the body-side peripheral wall portion 20 where the through hole 4 is formed can be reduced, and an increase in the size of the medical container 1 can be prevented. Furthermore, the other-side locking portion 7 can climb over the one-side locking portion 6 after elastically deforming the elastic portion 5, and therefore can easily climb over the one-side locking portion 6, which can prevent the one-side locking portion 6 from being scraped off and generating foreign matter such as resin pieces.

[0060] In the medical container 1 of this embodiment, the body 21 includes an inner storage section 23 and an outer main body-side peripheral wall section 20, and the main body-side peripheral wall section 20 is provided with the through-hole 4, elastic section 5, and one-way locking section 6, so that the through-hole 4, elastic section 5, and one-way locking section 6 can be provided without affecting the storage section 23 that stores the medical contents. Furthermore, when heating or cooling, for example, thawing or freezing, the medicinal liquid or the like stored in the medical container 1, hot water, running water, hot air, cold air, or the like can be passed through the through-hole 4 between the main body-side peripheral wall section 20 and the storage section 23, thereby quickly thawing or freezing the medicinal liquid or the like.

[0061] Furthermore, in the medical container 1 of this embodiment, the body-side peripheral wall 20 is provided with a guard portion 201 that protrudes outward from the container around the through-hole 4. This prevents the elastic portion 5 and the one-side locking portion 6 from colliding with other components, such as the floor, when the medical container 1 is dropped. In particular, in this medical container 1, the protruding position of the guard portion 201 on the body-side peripheral wall 20 is located further outward from the container than the protruding position of the one-side locking portion 6, which is useful in preventing the one-side locking portion 6 from colliding with other components, such as the floor. In this embodiment, the medical container 1 is a vial, and when the vial is placed in the nest, the guard portion 201 catches on the nest and holds the vial. The guard portion 201 can also serve as a flange when the user holds the medical container 1.

[0062] Furthermore, in the medical container 1 of this embodiment, the one locking portion 6 and the other locking portion 7 are disposed on the other axial side of the other end portion 33 of the cap body 3, so that the locking states of the one locking portion 6 and the other locking portion 7 can be seen and confirmed from the outside without being hidden by the cap body 3. Also, thawing or freezing of medicinal liquids or the like by passing hot water, running water, hot air, cold air, or the like through the through-hole 4 between the main body side peripheral wall portion 20 and the storage portion 23 can be quickly performed while being viewed from the outside.

[0063] The medical container of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the present invention.

[0064] In the above embodiment, the one locking portion 6 and the other locking portion 7 are disposed on the other axial side of the other end portion 33 of the cap body 3, but as shown in Figures 6 to 8, they may be disposed on one axial side of the other end portion 33 of the cap body 3. In this medical container 1, the configuration of the container body 2 is the same as the configuration in Figures 1 to 5.

[0065] 6, the cap-side peripheral wall portion 30 includes a small-diameter peripheral wall portion 301 and a large-diameter peripheral wall portion 302 that is connected to the other axial side of the small-diameter peripheral wall portion 301 and has a larger outer diameter than the small-diameter peripheral wall portion 301. The cap lid portion 31 closes an opening on one axial side of the small-diameter peripheral wall portion 301.

[0066] The small diameter peripheral wall portion 301 is cylindrical, and has an internal thread on its inner peripheral surface. A plurality of axially extending grooves are arranged side by side in the circumferential direction on the outer peripheral surface of the small diameter peripheral wall portion 301. The grooves extend in the axial direction from one axial edge of the small diameter peripheral wall portion 301 to the other axial edge.

[0067] The large diameter peripheral wall portion 302 is cylindrical. As shown in Fig. 7, the inner peripheral surface of the large diameter peripheral wall portion 302 is located closer to the outside of the container than the inner peripheral surface of the small diameter peripheral wall portion 301. In other words, the inner diameter of the large diameter peripheral wall portion 302 is larger than the inner diameter of the small diameter peripheral wall portion 301.

[0068] A second locking portion 7 is provided on the inner peripheral surface of the large diameter peripheral wall portion 302. The second locking portion 7 is provided on the cap body 3 so as to be positioned on the outer side of the container of the main body side peripheral wall portion 20 of the container body 2. In this configuration, the second locking portion 7 protrudes radially from the inner peripheral surface of the large diameter peripheral wall portion 302, i.e., toward the inside of the container. The second locking portion 7 extends in the axial direction from an edge on one axial side of the large diameter peripheral wall portion 302 to just before an edge on the other axial side. The width of the second locking portion 7, i.e., the dimension of the second locking portion 7 in the circumferential direction, is uniform. The second locking portion 7 is a rectangular rib.

[0069] Even with this configuration, by extending the elastic portion 5, which has the one-side locking portion 6, into the inside of the through hole 4, the thickness of the main body side peripheral wall portion 20 of the container main body 2 in which the through hole 4 is formed can be reduced, and the medical container 1 can be prevented from becoming larger.

[0070] In this medical container 1, when the cap body 3 is attached to the opening 22, as shown in Fig. 8, the elastic part 5 and the one locking part 6 are disposed on one side of the other axial end part 33 of the cap body 3. Therefore, the elastic part 5 and the one locking part 6 are hidden by the cap body 3. Furthermore, the through hole 4 is hidden by the cap body 3 except for the end part on the other axial side, and the end part on the other axial side of the through hole 4 is not hidden by the cap body 3. Therefore, the through hole 4, the elastic part 5, and the one locking part 6 can be provided so as to prevent foreign matter from entering through the through hole 4 while not affecting the storage part 23 that stores the medical contents.

[0071] In the above embodiment, the through hole 4 is formed in the body-side peripheral wall portion 20 of the container body 2. However, as shown in Fig. 9, the through hole 4 may be formed in the cap-side peripheral wall portion 30 of the cap body 3. The through hole 4 penetrates the cap-side peripheral wall portion 30 in the container-exterior direction. Also, as shown in Fig. 11, the one locking portion 6 and the other locking portion 7 are disposed on one axial side of the other-side end portion 33 of the cap body 3 in the axial direction.

[0072] In this embodiment, the cap-side peripheral wall portion 30 also includes a small-diameter peripheral wall portion 301 and a large-diameter peripheral wall portion 302 that is connected to the other axial side of the small-diameter peripheral wall portion 301 and has a larger outer diameter than the small-diameter peripheral wall portion 301. The cap lid portion 31 closes an opening on one axial side of the small-diameter peripheral wall portion 301.

[0073] The through hole 4 extends in the circumferential direction of the cap-side peripheral wall portion 30. The through hole 4 has, for example, a rectangular shape with its longitudinal direction aligned with the circumferential direction. In this embodiment, the through hole 4 is formed at the other axial end of the cap-side peripheral wall portion 30. Specifically, the through hole 4 penetrates the large-diameter peripheral wall portion 302 of the cap-side peripheral wall portion 30. As shown in FIG. 11 , the second hole edge portion 402, the third hole edge portion 403, and the fourth hole edge portion 404 of the through hole 4 are all located in the large-diameter peripheral wall portion 302, but the first hole edge portion 401 is located in the small-diameter peripheral wall portion 301.

[0074] Two through holes 4 are provided in the cap-side peripheral wall portion 30. The two through holes 4 are arranged at positions sandwiching the axis. Note that the cap-side peripheral wall portion 30 may have one through hole 4 or a plurality of three or more through holes 4.

[0075] The elastic portion 5 extends from the hole edge portion 40 that defines the through hole 4 in the cap-side peripheral wall portion 30 into the through hole 4. In this embodiment, the elastic portion 5 extends from the hole edge portion 40 that defines the through hole 4 in the large-diameter peripheral wall portion 302, specifically from the third hole edge portion 403, into the through hole 4. The elastic portion 5 elastically deforms inward and outward directions of the container. A one-side edge 51 located on one side of the elastic portion 5 in the axial direction is spaced apart from the first hole edge portion 401. A other-side edge 52 located on the other side of the elastic portion 5 in the axial direction is spaced apart from the second hole edge portion 402. An extending edge 53 of the elastic portion 5 is spaced apart from the fourth hole edge portion 404. A base end edge 54 of the elastic portion 5 in the axial direction is continuous with the third hole edge portion 403.

[0076] The one locking portion 6 projects inward from the elastic portion 5. The one locking portion 6 projects further inward from the container than the large diameter peripheral wall portion 302. The one locking portion 6 projects inward from the extending end portion including the extending edge 53 of the elastic portion 5.

[0077] As shown in FIG. 10, the other locking portion 7 is provided on the body-side peripheral wall portion 20 of the container body 2. As shown in FIG. 12, the other locking portion 7 is provided on the container body 2 so as to be positioned on the container inner side of the cap-side peripheral wall portion 30. Specifically, the other locking portion 7 is positioned on the container inner side of the peripheral wall large diameter portion 302. Furthermore, the other locking portion 7 protrudes from the body-side peripheral wall portion 20 toward the container outer side. In this embodiment, the other locking portion 7 is formed at one axial end of the body-side peripheral wall portion 20. Furthermore, the other locking portion 7 is formed in a portion including the boundary between the small diameter portion 202 and the large diameter portion 203 of the body-side tubular portion 200.

[0078] As the cap body 3 rotates about its axis, the other locking portion 7 abuts against the one locking portion 6, elastically deforming the elastic portion 5 radially outward and climbing over the one locking portion 6. In this embodiment, when the cap body 3 is closed, the other locking portion 7 of the body-side peripheral wall portion 20 abuts against the closing abutment portion 62 of the one locking portion 6 of the cap-side peripheral wall portion 30 from the circumferential direction. As the cap body 3 is further rotated from this state, the other locking portion 7 elastically deforms the elastic portion 5 outward from the container, and as a result, the one locking portion 6 provided on the elastic portion 5 also moves outward from the container. In other words, the other locking portion 7 abuts against the closing abutment portion 62 of the one locking portion 6 from the circumferential direction, pushing the elastic portion 5 and the one locking portion 6 outward from the container. At this time, the elastic portion 5 and the one locking portion 6 are energized. As a result, the other locking portion 7 passes over the apex 61 of the one locking portion 6 and passes the open abutment portion 63, completing the other locking portion 7 climbing over the one locking portion 6. Furthermore, once the one locking portion 6 has climbed over, the stored energy of the elastic portion 5 and the one locking portion 6 is released, and the positions of the elastic portion 5 and the one locking portion 6 in the container interior / exterior direction return to the positions they were in before being pushed in. In this way, the container body 2 containing a medicinal solution or the like can be closed with the cap body 3.

[0079] 12, in this medical container 1, an outer surface 500 of the elastic part 5 on the outer side of the container is flush with an outer peripheral surface 300 of the cap-side peripheral wall part 30 on the outer side of the container. In addition, since the elastic part 5 is located within the through-hole 4 provided in the cap-side peripheral wall part 30, the elastic part 5 is not hidden by the cap body 3.

[0080] 11, a rib 34 protrudes toward the inside of the container from the inner circumferential surface of the cap-side peripheral wall portion 30, specifically, from the inner circumferential surface of the large-diameter peripheral wall portion 302. The rib 34 is located closer to the terminal end in the rotation direction when closing the cap body 3 than the extended edge 53 of the elastic portion 5. Specifically, the rib 34 extends to a position that includes the fourth hole edge portion 404. The rib 34 also extends from the edge on one axial side of the large-diameter peripheral wall portion 302 to the edge on the other axial side. The rib 34 abuts against the other locking portion 7 of the container body 2, thereby preventing the cap body 3 from being over-closed.

[0081] Even with this configuration, by extending the elastic portion 5, which has the one-side locking portion 6, into the inside of the through hole 4, the thickness of the cap side peripheral wall portion 30 in which the through hole 4 is formed can be reduced, and the medical container 1 can be prevented from becoming larger.

[0082] In this medical container 1, the outer surface 500 of the elastic part 5 is flush with the outer peripheral surface 300 of the cap-side peripheral wall part 30, i.e., it does not protrude outward from the container beyond the outer peripheral surface 300 of the cap-side peripheral wall part 30, which prevents the elastic part 5 and one-side locking part 6 from colliding with other members, such as the floor, when the medical container 1 is dropped. Note that the same effect can be obtained even if the outer surface 500 of the elastic part 5 is configured to be located more inward of the container than the outer peripheral surface 300 of the cap-side peripheral wall part 30.

[0083] In the above-described embodiments, the body 21 includes the body-side peripheral wall 20 and the storage section 23, but it need not include the storage section 23 and may instead be composed of, for example, the body-side peripheral wall 20 and a bottom plate provided at the other axial end of the body-side peripheral wall 20. In this case, to form the through hole 4 in the body-side peripheral wall 20, for example, the area where the through hole 4 is to be formed may have an inner and outer two-layer structure, and the through hole 4 may be formed in the outer layer.

[0084] In the above-described embodiments, the through hole 4 is provided in the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30. However, the through hole 4 may be provided in both the body-side peripheral wall portion 20 and the cap-side peripheral wall portion 30. In this case, for example, the through hole 4 is provided in the body-side peripheral wall portion 20, an elastic portion 5 extends from the hole edge portion 40 of the body-side peripheral wall portion 20, and a first locking portion 6 is provided on the elastic portion 5 so as to protrude outward from the container. Furthermore, the through hole 4 is provided in the cap-side peripheral wall portion 30, an elastic portion 5 extends from the hole edge portion 40 of the cap-side peripheral wall portion 30, and a second locking portion 7 is provided on the elastic portion 5 so as to protrude outward from the container. As the cap body 3 rotates about its axis, the second locking portion 7 abuts against the first locking portion 6, causing at least one of the elastic portions 5 to elastically deform and overcome the first locking portion 6.

[0085] In the above-described embodiments, each elastic portion 5 extends in the circumferential direction of the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30, but multiple elastic portions 5 may extend therein. For example, a pair of elastic portions 5 extending in the circumferential direction may be provided in each through-hole 4, spaced apart from each other in the axial direction. In the above-described embodiments, each elastic portion 5 is a rectangular plate whose longitudinal direction is along the circumferential direction, but it may also be a U-shaped plate, that is, a rectangular plate with a notch cut out at a portion located in the center of the axial direction and on the base end side.

[0086] In the above-described embodiments, the extending edge 53 of the elastic portion 5 is spaced from the fourth hole edge 404 of the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30, and the base edge 54 of the elastic portion 5 is connected in the circumferential direction to the third hole edge 403 of the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30, but this is not limited to this. Both the extending edge 53 and the base edge 54 of the elastic portion 5 may be continuous in the circumferential direction with the hole edge 40 of the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30. In other words, the elastic portion 5 may extend in the circumferential direction so as to connect the hole edges 403, 404 of the body-side peripheral wall portion 20 or the cap-side peripheral wall portion 30.

[0087] In the above-described embodiments, the one locking portion 6 is provided at an extending end portion including the extending edge 53 of the elastic portion 5. However, the one locking portion 6 may be provided at a position other than both circumferential ends of the elastic portion 5, i.e., at a position between the extending edge 53 and the base edge 54 of the elastic portion 5. For example, the one locking portion 6 may be provided at a circumferential central portion of the elastic portion 5. Furthermore, the one locking portion 6 may be provided at an axial end portion of the elastic portion 5. For example, the elastic portion 5 may be configured to extend from a circumferential central portion of the second hole edge portion 402 of the through hole 4 to one axial side, and the one locking portion 6 may be provided at an end portion of this elastic portion 5 on one axial side.
