Abstract
Description
- The present invention relates to a before-use mixing container in which two types of medicinal solutions are stored in a separated state in one container, and these are mixed inside the container in use, and extracted for use.
- There are many medicinal solutions such as eye drops, which are chemically unstable in a mixed state or a dissolved state, and in case of use of such a medicinal solution, it is necessary to perform a mixing operation immediately before use. There is a before-use mixing container as a container in which two types of medicinal solutions are stored in a separated state, and these are mixed in the container in use, and extracted for use.
- As a before-use mixing container, for example, there has been known a container adopting a system that one medicinal solution and another medicinal solution are respectively contained in a first container body and a second container body in a separated state by use of isolation members in which one member having an opening portion and the other member having an opening portion are slidably fit into each other so that their opening portions do not face each other, and the both opening portions are made to face each other by a sliding operation of the isolation members, to mix the two types of medicinal solutions (refer to Patent Document 1).
-
- [Patent Document 1] Japanese Patent No. 3228376
- However, since an uncovering operation is accompanied at the time of mixing the two types of medicinal solutions in the before-use mixing container in
Patent Document 1, there is, for example, a concern that the medicinal solutions may spill out when an uncovering operation is performed in a state in which the container is turned upside down by mistake. Accordingly, it is necessary to adopt a mixing method independent of an uncovering operation in order to mix two types of medicinal solutions even when such an erroneous operation is performed. - The present invention has been achieved in consideration of the above-described circumstances. It is a primary object of the present invention to provide a before-use mixing container in which it is possible to perform a mixing operation for two types of medicinal solutions in the container independently of an uncovering operation for a cap or the like.
- That is, the scope of the present invention is as follows.
- [1] A before-use mixing container including
- a movable body which has a bottomed cylindrical tube section, a ceiled cylindrical inner tube which is consecutively installed upright on an inner side in a circumferential direction from an inner surface of the tube section, that partitions an internal space of the tube section into two upper and lower chambers, and a first opening portion drilled in a ceiling plane of the inner tube, and in which a first medicinal solution is contained in the lower chamber,
- an adapter which has a hollow cylindrical fit-in tube section which is tightly fit into the upper chamber of the movable body to be assembled so as to be rotatable with respect to the movable body, a partition wall surface which is provided on an inner surface of the fit-in tube section, and is tightly attached to the ceiling plane of the inner tube of the movable body in a state in which the partition wall is assembled to the movable body, and a second opening portion which is drilled in the partition wall surface so as not to overlap the first opening portion, and
- a container main body which has a lower mouth tube section which is tightly fit into the upper chamber surrounded by an upper surface of the partition wall surface of the adapter and the inner surface of the fit-in tube section, to be assembled so as not to be rotatable with respect to the adapter, and in which a second medicinal solution is contained, and in the container,
- when the movable body is relatively rotated with respect to the container main body, the first opening portion of the movable body and the second opening portion of the adapter are overlapped, and the container is capable of mixing the first medicinal solution and the second medicinal solution before use.
- [2] In the before-use mixing container according to [1],
- the fit-in tube section of the adapter is provided with a large diameter section and a small diameter section having circular arc shapes in plan view, and in a state in which the fit-in tube section of the adapter is assembled to the upper chamber of the movable body, the large diameter section and the small diameter section of the fit-in tube section are respectively spaced from the inner surface of the tube section of the movable body to generate gaps, and
- a vertical line with a height exceeding a spaced distance between the inner surface of the tube section and the large diameter section, and with a height which does not exceed a spaced distance between the inner surface of the tube section and the small diameter section is provided on the inner surface of the tube section of the movable body, and the longitudinal vertical line faces the small diameter section.
- [3] In the before-use mixing container according to [2], when the movable body is relatively rotated with respect to the container main body and the vertical line provided on the inner surface of the tube section of the movable body reaches a boundary portion between the small diameter section and the large diameter section of the fit-in tube section, the first opening portion and the second opening portion are overlapped.
- According to the before-use mixing container of the present invention, since the container main body and the adapter are assembled so as not to be relatively rotatable, the adapter and the movable body are assembled so as to be relatively rotatable, and the two types of medicinal solutions are mixed by merely relatively rotating the movable body with respect to the container main body, it is possible to perform a mixing operation for the two types of medicinal solutions in the container independently of an uncovering operation for a cap or the like.

As shown inFIG. 3 , theinner ledge 12 and theinner tube 13 of themovable body 1 compose a partition section that partitions the internal space of thetube section 11 into two upper and lower chambers, and fourlocking protruding lines 15 are consecutively installed along its circumferential direction, and positioning protruding lines 16 (16 a and 16 b) are provided so as to protrude upward from substantially the central portion of the twolocking protruding lines 15 facing each other on the inner surface of thetube section 11 composing the upper chamber above the partition section. Then, a first medicinal solution A is contained in the lower chamber under the partition section. - The
adapter 3 is an inj ection-molded part made of synthetic resin. As shown inFIGS. 1 , 2, and 4, a hollow cylindrical fit-intube section 31 is a primary member thereof, and the outer diameter of the fit-intube section 31 is designed in size to have a diameter smaller to a certain extent than the inner diameter of thetube section 11 composing the upper chamber of themovable body 1. Twolocking protruding lines 32 with a length which is approximately the half circle of the fit-intube section 31 are consecutively installed so as to go around the fit-intube section 31 on the outer surface of the fit-intube section 31, and in the case in which theadapter 3 is tightly fit into the upper chamber of themovable body 1, theselocking protruding lines 32 are locked with thelocking protruding lines 15 of themovable body 1 in the axial line direction, thereby making theadapter 3 be assembled so as not to be allowed to be fit and removed and to be rotatable with respect to themovable body 1. In addition, at the time of assembling theadapter 3 to themovable body 1, it is recommended thatgroove portions locking protruding lines positioning protruding lines movable body 1, and theadapter 3 be pushed downward along thepositioning protruding lines - On the other hand, a large number of longitudinal locking
vertical lines 33 are provided so as to protrude at regular intervals along the circumferential direction starting from the upper end opening portion on the inner surface of the fit-intube section 31, and lockingprotrusions 34 for locking are provided so as to protrude on the distal ends of the respective longitudinal lockingvertical lines 33. Then, apartition wall surface 35 that partitions the internal space of the fit-intube section 31 into two upper and lower chambers is provided on the lower side of thelocking protrusions 34, and a short cylindrical airtightcap tube section 36 with a diameter shorter than that of the fit-intube section 31 is provided upright on the peripheral edge of thepartition wall surface 35, and asecond opening portion 35 a is drilled in the inner side of the airtightcap tube section 36 in thepartition wall surface 35. Thesecond opening portion 35 a is disposed so as not to overlap the first openingportion 13 b of themovable body 1 in a state in which theadapter 3 is assembled to themovable body 1, and is provided at a position at which thesecond opening portion 35 a overlaps the first openingportion 13 b when themovable body 1 is made to slide with respect to theadapter 3 to rotate around the center of axis. Then, as shown inFIG. 2 , theadapter 3 and themovable body 1 are assembled in a state in which thepartition wall surface 35 of theadapter 3 and the fit-intube section 31 on the side lower than thepartition wall surface 35 are fit at the outside of theinner tube 13 of themovable body 1 to be tightly attached in a liquid-tight manner. - A container
main body 4 is a blow molded article made of synthetic resin. As shown inFIGS. 1 , 2, and 5, a second medicinal solution B is contained in the containermain body 4, and a lowermouth tube section 42 is consecutively installed upright via its shoulder portion on the lower end of acylindrical body section 41, and an uppermouth tube section 43 on which ascrew portion 43 a is carved is consecutively installed upright via the shoulder portion on the upper end of thebody section 41. Four longitudinal lockingvertical lines 42 a are provided so as to protrude at regular intervals in the circumferential direction on the outer surface of the lowermouth tube section 42, and aperipheral protrusion line 42 b is installed around on the outer surface of the lower end of the lowermouth tube section 42. In a state in which the lowermouth tube section 42 is tightly fit into the upper chamber surrounded by the upper surface of thepartition wall surface 35 and the inner surface of the fit-intube section 31 of theadapter 3, as shown inFIG. 2 , the lockingvertical lines 42 a of the lowermouth tube section 42 are fit into between the lockingvertical line 33 and the lockingvertical line 33 on the inner surface of the fit-intube section 31, thereby the containermain body 4 and theadapter 3 are assembled so as not to be rotatable with respect to each other, and theperipheral protrusion line 42 b of the lowermouth tube section 42 is locked in the axial line direction with the lockingprotrusion 34 on the inner surface of the fit-intube section 31, thereby the containermain body 4 and theadapter 3 are assembled so as not to be allowed to be fit and removed. - The
nozzle 5 is an injection-molded part made of synthetic resin. As shown inFIGS. 1 and 2 , thenozzle 5 is provided with a short cylindrical airtightcap tube section 51 which is tightly fit into the inner surface of the upper end opening portion of the uppermouth tube section 43 of the containermain body 4, aceiling plane 52 having anouter ledge 52 a that blocks up the upper end opening portion of the airtightcap tube section 51, and which is formed so as to protrude outward in a radial direction of the airtight cap tube section, and tightly touches the end face of the upper end opening portion of the uppermouth tube section 43 of the containermain body 4 in a liquid-tight manner, and anozzle section 53 which is formed so as to swell out on the central portion of theceiling plane 52. An extractingorifice 53 a is provided in the apical portion of thenozzle section 53, and the extractingorifice 53 a is configured to have a depressed orifice wall in an inverted circular truncated cone shape from the apical portion of thenozzle section 53 up to theceiling plane 52, and is configured to be communicated with the internal space of the airtightcap tube section 51 through an extractinghole 53 b drilled in the lower end of the extractingorifice 53 a of thenozzle section 53. - The
cap 6 is an injection-molded part made of synthetic resin. As shown inFIGS. 1 and 2 , thecap 6 is composed of aceiling plane 61, anupper tube body 62 in a tapered cylindrical shape whose diameter is extended gently downward from the peripheral edge of theceiling plane 61, and alower tube body 63 in a tapered cylindrical shape whose diameter is extended gently downward via the shoulder portion from theupper tube body 62. Ascrew portion 63 a screwed in thescrew portion 43 a provided on the uppermouth tube section 43 of the containermain body 4 is provided on the inner surface of thelower tube body 63, and aconvex portion 61 a which is tightly attached to the opening edge of the extractingorifice 53 a is provided on the lower surface of theceiling plane 61 in a liquid-tight manner. Further, anantislip knurl 64 is formed on the outer surface of thelower tube body 63. - That is, the before-use mixing container of the present invention is configured so that the
bottom cover 2, themovable body 1, theadapter 3, the containermain body 4, thenozzle 5, and thecap 6 are integrally assembled, and by use of theceiling plane 13 a of theinner tube 13 of themovable body 1 and thepartition wall surface 35 of theadapter 3 as partition walls, the first medicinal solution A is contained in the lower chamber of themovable body 1 and the second medicinal solution B is contained in the containermain body 4. Then, regarding the possibility of rotation between the above-described respective members with each other, themovable body 1 and theadapter 3 are assembled so as to be relatively rotatable with respect to each other, and theadapter 3 and the containermain body 4 are assembled so as not to be relatively rotatable with respect to each other. - In use of the before-use mixing container of the present invention, a mixing operation for the first medicinal solution A and the second medicinal solution B, and an extraction operation for the mixed liquid are required. Regarding the former operation, as shown in
FIG. 6A , themovable body 1 is rotated in a counterclockwise direction until thefirst opening portion 13 b overlaps thesecond opening portion 35 a in a state in which the container is turned upside down while grasping the containermain body 4. Then, as shown inFIG. 6B , the first medicinal solution A contained in themovable body 1 falls into the containermain body 4, thereby achieving mixing of the first medicinal solution A and the second medicinal solution B. Next, at the time of extracting the mixed liquid, provided that the container is returned to be in the original vertical direction, and thecap 6 is screwed out and the container is turned upside down, the mixed liquid passes through the extractinghole 53 b to be extracted from the extractingorifice 53 a. That is, it is possible to perform a mixing operation for the first medicinal solution A and the second medicinal solution B independently of an extraction operation in the present invention. - In the present embodiment, as shown in
FIG. 4 , alarge diameter section 31 a and asmall diameter section 31 b which are in substantially circular arc shapes in plan view are formed under thelocking protruding lines 32 on the outer surface of the fit-intube section 31 of theadapter 3, and in a state in which the fit-intube section 31 of theadapter 3 is assembled to the upper chamber of themovable body 1, thelarge diameter section 31 a and thesmall diameter section 31 b of the fit-intube section 31 are respectively spaced from the inner surface of thetube section 11 of themovable body 1 to generate gaps. Further, as shown inFIGS. 2 and 3 , a longitudinalvertical line 17 with a height exceeding a spaced distance between the inner surface of thetube section 11 and thelarge diameter section 31 a, and with a height which does not exceed a spaced distance between the inner surface of thetube section 11 andsmall diameter section 31 b is provided so as to protrude on the inner surface of thetube section 11 of themovable body 1, and thisvertical line 17 faces thesmall diameter section 31 b. With such a configuration, it is difficult to make thevertical line 17 on the inner surface of thetube section 11 of themovable body 1 climb over thelarge diameter section 31 a rotate, and therefore, it is possible to keep thevertical line 17 to always face thesmall diameter section 31 b. - Further, in the present embodiment,
protrusion lines small diameter section 31 b of theadapter 3, and lockinggroove lines protrusion line 31 c in the vicinity of the one end side in the circumferential direction of thesmall diameter section 31 b and the other end side in the circumferential direction of thelarge diameter section 31 a (the right end portion of the large diameter section inFIG. 4C ), and between theprotrusion line 31 d in the vicinity of the other end side in the circumferential direction of thesmall diameter section 31 b and the one end side in the circumferential direction of thelarge diameter section 31 a (the left end portion of the large diameter section inFIG. 4C ). - Then, in manufacturing of the container, at the time of making the fit-in
tube section 31 of theadapter 3 be tightly fit into the upper chamber of themovable body 1, provided that the lockinggroove line 31 e of theadapter 3 corresponding to a rotation starting position is fit into thevertical line 17 on the inner surface of thetube section 11 of themovable body 1 to make theadapter 3 be assembled to themovable body 1, in a mixing operation, when themovable body 1 is made to relatively rotate in the direction of an arrow inFIG. 6A with respect to the containermain body 4, and thevertical line 17 climbs over theprotrusion line 31 c to pass through thesmall diameter section 31 b, and climbs over theprotrusion line 31 d to be engaged with the lockinggroove line 31 f, themovable body 1 is no longer able to be rotated, which terminates the rotation operation. That is, the lockinggroove lines first opening portion 13 b and thesecond opening portion 35 a are overlapped at the end of rotation, it is possible for a user to reliably perform a mixing operation. - The synthetic resins used for the above-described respective members are not particularly limited in type. For example, low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), polypropylene (PP), and the like may be appropriately combined for use. In particular, in order to improve the liquid-tight performance between the respective members, it is preferable that LDPE or LLDPE is used for the
bottom cover 2 and HDPE is used for themovable body 1 in order to improve the liquid-tight performance between thebottom cover 2 and themovable body 1. Further, it is preferable that HDPE is used for themovable body 1 and PP is used for theadapter 3 in order to improve the liquid-tight performance between themovable body 1 and theadapter 3. As a result of study by the present inventors, a combination of synthetic resins in which the liquid-tight performance between the respective members is maximized is, from a comprehensive point of view, in the case in which LLDPE is used for the bottom cover, HDPE is used for the movable body, PP is used for the adapter, PP is used for the container main body, LDPE is used for the nozzle, and PP is used for the cap. - The embodiment of the present invention has been described above with reference to
FIGS. 1 to 6 . However, modes of the respective members may be appropriately modified within a range which does not deviate from the scope of the present invention. For example, in the above-described embodiment, theceiling plane 13 a and thepartition wall surface 35 are used as partition walls for the first medicinal solution A and the second medicinal solution B, and thefirst opening portion 13 b and thesecond opening portion 35 a are respectively provided therein. However, unless the opening portions provided in the upper and lower partition walls are not overlapped before mixing, to separate the first medicinal solution A and the second medicinal solution B, a plurality of opening portions in the upper and lower partition walls may be provided. - The components of the container of the present invention were manufactured by use of synthetic resins shown in Table 1, test samples (A to D) in which the movable bodies and the container main bodies filled with medicinal solutions were assembled into products were prepared, and the liquid-tight performance between the respective components of these test samples were evaluated. The evaluations of the liquid-tight performance were carried out so that the test samples were overturned to be left in a state in which normal pressure was reduced by 70 kPa, and after the pressure was returned to normal pressure ten minutes later, it was visually confirmed whether or not there was liquid leakage from the gaps between the fitting portions of the respective components. In addition, the test samples having shapes according to those in
FIGS. 1 to 6 , and in which its total height is 100 mm and the diameter of the tube section of the movable body is 22 mm were used. The results are shown in Table 2. -
TABLE 1 Bottom Movable Container Test sample cover body Adapter main body Nozzle Cap A LLDPE LDPE HDPE PP LDPE PP B LDPE HDPE HDPE C LDPE LDPE PP D LLDPE HDPE PP PP: Polypropylene LLDPE: Linear low-density polyethylene HDPE: High-density polyethylene LDPE: Low-density polyethylene -
TABLE 2 Bottom cover Movable Adapter Container Test Movable body Container main body Nozzle sample body Adapter main body Nozzle Cap A x x ∘ ∘ ∘ B ∘ x ∘ C x x ∘ D ∘ ▴ ∘ ∘: No leakage, ▴: Slight exudation, x: Leakage - The present invention may have broad applicability as a before-use mixing container in which it is possible to perform a mixing operation for two types of medicinal solutions in its container independently of an uncovering operation for a cap or the like.
