Description

  The present invention relates to an overcap that is used by further covering a cap in a closed state such as a container with a cap, or a container equipped with such an overcap. In particular, it is preferably used for a vial in which the internal contents can be sealed with a stopper and a flip cap for preventing the stopper from dropping off.

  Conventionally, as a container with a cap, a vial is known in which a mouth portion of a bottle container is closed in a sealed state with a rubber cap (a cap) and a flip cap (see, for example, Patent Document 1 or Patent Document 2). Such a vial is used, for example, in such a manner that a freeze-dried medicine is stored in an aseptic state, and for example, distilled water is poured into the medicine to dissolve it, and this is sucked into a syringe for injection. For example, the medicine is sealed in the vial by the following process. First, for example, a drug solution is put into a vial from the mouth and the rubber stopper is in a semi-sealed state, and this is put into a freeze dryer and subjected to freeze-drying treatment for a predetermined time to obtain a freeze-dried medicine such as a solid powder. Seal with a rubber stopper. Next, for example, a flip cap in which a synthetic resin cap body is attached to a band ring made of aluminum or the like by an engaging means or the like is placed over the rubber plug, and the skirt portion of the band ring is wound around the outer peripheral surface of the mouth. Tighten. In this state, conveyance and storage are performed. In use, the cap body of the flip cap is pulled out to be removed from the band ring, and distilled water is injected into the inside by sticking an injection needle into the upper surface of the central portion of the exposed rubber stopper. The drug is dissolved by the injected distilled water, and the drug is administered by sucking this solution into a syringe and injecting it into a patient.

  Incidentally, some oral drugs (oral preparations) and external preparations need to be maintained and accommodated in a sterile state until use. For this reason, a vial is used in order to accommodate such an oral preparation and an external preparation other than the injection medicine as described above. In this case, if such oral preparations and external preparations are to be stored in the form of powder or chemical solution, they should be put inside and immediately sealed with a rubber stopper, which is a chemical solution but freeze-dried. After lyophilization as described above, it is sealed with a rubber stopper, and thereafter, as in the case of the above-mentioned injectable drug (injection), a flip cap is put on and the band ring is tightened to perform a sealing process. It will be. That is, whether it is an injection or an oral preparation other than an injection, both are enclosed in a vial through the same process, and are provided to a medical institution or the like while being enclosed in this vial. . Then, in a medical institution, the cap body of the flip cap is removed, the sealing seal by the band ring is removed and the rubber stopper is removed, and if it is a freeze-dried drug, it is orally administered to the patient after dissolution. It will be.

  Under such circumstances, even if it is an injection or an oral preparation, the overall shape of the vial in which it is sealed and the sealing structure are the same as each other. May cause a medicinal error such as misuse for use, or misuse for injection. For this reason, as a measure for preventing misuse, the pharmaceutical industry adopts the indication of “no injection” on the label of the vial to raise the attention of doctors and nurses handling in the medical field. However, in the medical field, there is a demand for a measure that can identify at a glance whether it is an injection or an oral preparation.

  Regardless of whether it is an injection or an oral preparation, it is necessary to remove (open) the cap body of the flip cap by hand, etc. at the time of use. In many cases, the hand touches the upper surface of the rubber stopper, or the upper surface of the rubber stopper is rubbed by hand. For this reason, there is a need for a method that can surely avoid touching the upper surface of the rubber stopper without increasing labor at the medical site.

  The present invention has been made in view of such circumstances, and the object of the present invention is to distinguish the inclusions at a glance while being sealed in the same sealing structure with respect to the container with a cap. An object of the present invention is to provide an overcap as a means that can be realized, or in addition to such distinguishability, as a means that can perform a lid opening operation without touching with a hand.

  In order to achieve the above object, according to the present invention, as an overcap, an inner surface shape that can be covered by covering the cap of a container with a cap whose mouth is closed by a cap, and a cap of the container with the cap In the mounted state of covering from above, the outer shape of the mouth side of the container with the cap is converted to a shape bulging outward from the cap (Claim 1). ).

  In the case of the present invention, by placing the overcap on the container with a cap, the outer shape on the mouth side bulges outward from the cap as compared to the unmounted state, and the container is It is possible to convert the entire shape including the difference into a greatly different one. For this reason, it is possible to see the difference in the inclusions based on the difference in the overall shape by attaching or removing the overcap according to the difference in the inclusions (for example, oral or injection). It becomes possible to identify with. Thereby, it becomes possible to prevent the occurrence of misuse based on the misidentification of the inclusion.

  In the said invention, the structure couple | bonded with the coupling | bonding force larger than the holding force which hold | maintains the cap in a closed state with the cap in the said mounting state can be employ | adopted (Claim 2). By doing so, it is possible to remove the cap at the same time by the operation of removing the overcap to open the lid, and contamination on the mouth side that may occur when the cap is removed by hand. It is possible to reliably avoid the possibility of the occurrence of and maintain a clean hygienic state.

  As a specific configuration for realizing such coupling, a cylindrical main body having the inner surface shape and the outer surface shape and receiving the cap from the lower end opening, and a welding means, an adhesion means, a joining means for coupling to the cap, A top wall that projects outwardly larger than the cap and covers the upper surface of the cap as the cylindrical main body. And a cylindrical wall portion that extends downward from the outer periphery of the top wall portion and protrudes toward the outer peripheral side of the lower container in a state of covering the outer peripheral surface of the cap. Item 3). By doing in this way, the concrete structure which can implement | achieve the effect | action of Claim 1 or Claim 2 reliably is provided.

  Furthermore, the coupling means can be configured by one or more claw portions that project inward and obliquely upward from the cylindrical wall portion and engage with the lower surface of the lower end corner of the peripheral edge of the cap. (Claim 4). By doing so, it becomes possible to form a coupling means that can be easily manufactured by synthetic resin molding and that can be reliably coupled to the cap.

  In this case, as the claw portion, the cap-attached container is covered with the cap from above the cap, and is pushed against the outer peripheral surface of the peripheral portion of the cap and relatively moved while elastically deforming outward. It can also be configured to be elastically restored by getting over and engage with its lower surface (Claim 5). By doing in this way, mounting | wearing becomes possible easily and reliably based on the elastic deformation of nail | claw part itself.

  In the overcap of the present invention, an extension portion formed so as to extend upward from the cap in the mounted state can be integrally provided on the upper side (Claim 6). By doing this, the cap is opened by performing an operation of grasping the extension portion and applying a pulling force in a direction crossing the central axis (this operation is referred to as “pick” in this specification). Based on this principle, the operation can be reliably performed with a light operating force. Furthermore, by forming an uneven portion on the outer surface of the extending portion (Claim 7), it is easier to handle when performing the gripping operation, and a reliable operation can be expected.

  Furthermore, the overcap of the present invention further includes a downward stepped portion facing downward on the outer peripheral side with respect to the mouth portion of the container, and the cylindrical wall portion is inwardly and obliquely upward from the cylindrical wall portion in the mounted state. One or two or more second claw portions that protrude toward and engage with the downward stepped portion of the mouth portion can be integrally formed (claim 8). By doing in this way, even if an external force is applied upward from the lower end of the cylindrical wall part due to an inadvertent collision between the lower end of the cylindrical wall part and some object, the second claw part is directed to the downward stepped part. Due to the engagement, the upward relative displacement of the overcap is prevented, and it is possible to prevent the cap from being opened based on the coupling force or coupling means, and it is possible to prevent the overcap from falling off. .

  Further, as a second invention relating to a container equipped with an overcap, the container is a container whose mouth is closed by a cap, and the overcap according to any one of claims 1 to 8 is put on the cap. It was supposed to be externally packaged (claim 9).

  In the case of this 2nd invention, the container which can obtain the above-mentioned operation of an overcap can be realized.

  As described above, according to the overcap according to any one of claims 1 to 8, by setting the overcap to the cap-equipped container, as compared with the unmounted state. , The overall shape including the container can be converted into a greatly different one, and the difference in the inclusion can be based on the difference in the overall shape by attaching or removing the overcap according to the difference in the inclusion. Can be identified at a glance. Thereby, generation | occurrence | production of the misuse based on the misidentification of an enclosure can be prevented.

  In particular, according to the second aspect, the cap can also be removed and opened at the same time by the overcap removal operation, and the cap can be made to function as a cap opening jig. In addition, it is possible to reliably avoid the possibility of the occurrence of contamination on the mouth side, which may occur when the cap removal operation is performed by hand, and to maintain a clean sanitary state.

  According to the third aspect, it is possible to provide a specific configuration capable of reliably realizing the above effects.

  According to the fourth aspect, by employing the engaging means by the claw portion as the coupling means, the coupling means can be easily manufactured by synthetic resin molding, and the coupling with the cap can be reliably performed.

  According to the fifth aspect, the mounting operation can be easily and reliably performed based on the elastic deformation of the claw portion itself.

  According to the sixth aspect, by performing an operation such as gripping and prying the extension portion, the cap opening operation can be surely performed with a light operation force based on this principle. According to the seventh aspect of the present invention, by forming the concavo-convex shape portion on the outer surface of the extending portion, it is possible to make handling easier when performing the gripping operation and to ensure a reliable operation. Will be able to.

  Furthermore, according to the eighth aspect, even if an upward external force acts from the lower end of the cylindrical wall portion due to an inadvertent collision between the lower end of the cylindrical wall portion and any object, the second claw portion causes the overcap. So that the cap can be prevented from being opened based on the coupling force or coupling means, and the cap can be prevented from falling off. Become.

  Moreover, according to the container equipped with the overcap according to claim 9, it is possible to realize a container with the effect of the overcap according to any one of claims 1 to 8.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
1 to 3 show a mounted state in which the overcap 2 according to the first embodiment of the present invention is mounted on a container with a cap. Prior to the description of the overcap 2, a vial in a sealed state as a capped container to which the overcap 2 is attached will be described first. In addition, as this container with a cap, the same thing is used as a mounting | wearing object not only in 1st Embodiment but in the following other embodiment.

  As shown in FIG. 3, the vial 3 is mainly made of glass so as to have a tapered shape from the bottomed main body portion 31 to the upper end side mouth portion 32. The mouth portion 32 is opened upward, and a predetermined dimension range is formed thicker than the other from the opening end side, and a downward surface is formed below the outer peripheral surface of the thick portion 33 corresponding to the thickness difference. A downward stepped portion 34 is formed. After the medicine is put into the main body 31 from the open mouth portion 32, the vial 3 is plugged with a rubber stopper (inner stopper) 4, and the flip cap 5 is placed on the stoppered rubber stopper 4. Covered and closed. The flip cap 5 is one in which, for example, a band seal ring 51 made of an aluminum thin plate is integrally assembled with an upper lid 52 that is a cap made of synthetic resin by means such as engagement. Then, the skirt portion 511 of the band seal ring 51 is wound and tightly contacted from the outer peripheral surface of the thick portion 33 to the downward step portion 34, thereby reliably preventing the rubber stopper 4 from falling off and sealing in a sealed state. Will be maintained. This band seal ring 51 is in a state where the central region of the upper surface of the rubber plug 4 is cut out, and the upper surface of the rubber plug 4 is exposed in order to insert the injection needle when the upper cover 52 is opened. It has become. An upper lid 52 is placed over the exposed upper surface of the rubber stopper 4 to protect it.

  The upper lid 52 includes a top wall portion 521 and a peripheral edge portion 522 that bends downward from the outer periphery and hangs down. A fitting portion 523 is formed at the center of the inner wall surface of the top wall portion 521. Then, the upper lid 52 is engaged with the inner peripheral edge 512 of the band sealing ring 51 with respect to the fitting portion 523 so as to be engaged with the band sealing ring 51, and the upper lid 52 is opened by prying the upper lid 52. Thus, the engagement with the inner peripheral edge 512 is released and the band seal ring 51 is separated. In addition, the inner peripheral edge 512 is integrally molded with the upper lid 52, and the inner peripheral edge 512 is broken along the breaking line (weakening line) on the band sealing ring 51 side by the above-described opening operation. 51 may be separated from each other. The upper lid 52 is maintained in a closed state with respect to the rubber plug 4 by a holding force based on the frictional resistance of each other with respect to the outer peripheral surface of the band sealing ring 51 except for the engagement with the inner peripheral edge 512 described above. That is, the holding force for holding the upper lid 52 in the closed state is mainly based on the frictional resistance, and the engagement with the inner peripheral edge 512 is set so as to be released with as little operating force as possible. The contribution of the engagement as the holding force is negligible. As described above, the outer shape of the vial 3 in the sealed state has a narrow neck portion extending from the upper mouth portion (see FIG. 3) of the main body portion 31 as shown in FIG. 4, and the downward stepped portion 34 (see FIG. 3) from above. And the two-step step portion is formed such that the diameter is expanded by the skirt portion 511 of the band ring 51 covering the outer surface, and further the step diameter is expanded by the lower end corner portion 524 of the peripheral edge portion 522 of the upper lid 52. It is a thing.

  Next, the overcap 2 of the present embodiment will be described with reference to FIGS. 1 to 4. The overcap 2 is a first claw that is a coupling means between the cylindrical main body 21 whose lower end is opened and the flip cap 5. , And second claw portions 23, 23,... For supplementing the maintenance of the wearing state. The cylindrical main body 21 includes a top wall portion 211 and a cylindrical wall portion 212 that extends downward from the outer periphery of the top wall portion 211. The cylindrical wall portion 212 covers a region in the vertical direction from the top of the upper lid 52 of the sealed vial 3 to the upper end side position of the main body portion 31, in other words, a region having a smaller diameter than the main body portion 31 on the mouth portion 32 side. , Having a length (height) that can be substantially the same diameter as the main body 31 and an outer diameter, and a predetermined number of first claw portions 22, 22,. The two claw portions 23, 23,... Are alternately arranged at equal intervals in the circumferential direction. Opening windows 213 and 214 are formed at portions where the claw portions 22 and 23 are formed so as to surround the claw portions 22 and 23 and penetrate the inside and the outside. Each opening window 213, 214 has its opening width gradually widened upward for die cutting during the molding of synthetic resin, and the inside of each claw portion 213, 214 described later with respect to the top wall portion 211 side. The shape is set so as to be cut larger than the protruding amount.

  The top wall portion 211 and the cylindrical wall portion 212 constituting the tubular main body 21 have an inner surface shape that can cover the top wall portion 521 of the upper lid 52 by covering the lower end opening from the upper side of the upper lid 52 of the flip cap 5, and the flip cap 5. It is provided with an outer surface shape that can be changed into a columnar shape substantially the same as that of the main body portion 31 of the vial 3 by placing it on the top and putting it in the mounted state (the state shown in each drawing of FIGS. 1 to 3). . For example, when the overcap 2 is attached, the mouth side has a tapered shape as shown in the lower half of the vial 3 as shown in the lower half of FIG. 4, and the substantially cylindrical shape as shown in FIG. It can be converted into an overall shape. More specifically, as an additional configuration, the cylindrical wall portion 212 is formed in a taper shape so as to slightly increase in diameter toward the lower end opening, and when the upper cover 52 is covered from above, the cylindrical wall portion 212 is formed. The inner peripheral surface of the upper lid 52 gradually narrows and the inner peripheral surface and the outer peripheral surface of the peripheral edge portion 522 of the upper lid 52 come into contact with each other. It is made to hold | maintain and couple | bond in the overcap 2. FIG.

  Each first claw portion 22 protrudes inward and obliquely upward from a predetermined upper position of the cylindrical wall portion 212 so as to be engageable with the lower surface of the lower end corner portion 524 of the peripheral edge portion 522 of the upper lid 52. Has been. That is, each first claw portion 22 protrudes toward the center axis X side to the inner position from the outer diameter position of the lower end corner portion 524 of the peripheral edge portion 522 of the upper lid 52. On the other hand, each of the second claw portions 23 similarly projects inward and obliquely upward from a predetermined lower position of the cylindrical wall portion 212 so that the downward stepped portion 34 on the outer peripheral side of the mouth portion 32 of the vial 3 is mounted. The lower surface (actually, the lower surface is covered with the skirt portion 511 of the band seal ring 51 and is thus formed to be engageable with the skirt portion 511). That is, each second claw portion 23 protrudes to an inner position (a position on the central axis X side) than at least the outer peripheral surface of the thick portion 33. Each first claw portion 22 holds the upper lid 52 between the top wall portion 211 and holds the upper lid 52. If the overcap 2 is removed, the upper lid 52 is also held in the overcap 2 while being held in the overcap 2. The upper lid 52 is connected to the overcap 2 so as to be removed together with the upper cap 52. On the other hand, when each second claw portion 23 collides with something at the lower end opening side of the cylindrical wall portion 212 of the overcap 2 and an upward impact force acts on the overcap 2, the impact force is applied to the second claw portion. By transmitting to the downward step portion 34 first through 23, the impact force is prevented from being directly transmitted to the upper lid 52 through the first claw portion 22. That is, in order to make such a role more reliable, in the mounted state, each second claw portion 23 is in contact with the lower surface side of the downward stepped portion 34 and is in an engaged state. It is preferable that the claw portion 22 is in an engageable state with a small gap in the vertical direction between the lower surface of the lower end corner portion 524 of the upper lid 52.

  As for the number and arrangement of the claw portions, in the example shown in the figure, three first claw portions 22, 22,... (See also FIG. 5) and three second claw portions 23, 23,. Provided in alternating positions at each position equally divided by the total number, and provided so that the first claw portion 22 and the second claw portion 23 are located on both sides in the diametrical direction across the central axis X However, this shows a preferable state. As a minimum, at least one each is sufficient, or two first claw portions 22 and two second claw portions 23 are respectively arranged, or four or more are respectively arranged in the same manner as described above. You may make it provide. Further, the claw portions 22 and 23 are elastic in the inward / outward direction (radial direction with respect to the central axis X) when they are put on the mounting state from the state before the mounting (the state shown in FIG. 4) based on the characteristics of the synthetic resin material. The thickness dimension, shape, etc. are set so that it can be deformed and bent.

  The above-described overcap 2 is lowered from the state in which the lower end opening is opposed to the upper lid 52 with respect to the vial 3 sealed with the rubber cap 4 and the flip cap 5 as shown in FIG. Cover. When covering, the front end side of each claw part 22, 23 is pressed against the outer peripheral surface of the peripheral part 522 of the upper lid 52 to be elastically deformed outward, and in addition, the front end side of the second claw part 23 is the band seal ring 51. The outward elastic deformation is continued by the outer peripheral surface. And each 2nd nail | claw part 23 is elastically restored by reaching along the skirt part 511 of the banding ring 51 to the downward step part 34, and it engages with the lower surface of the downward step part 34, while each 1st nail | claw part 22 is By moving over the lower end corner portion 524 of the upper lid 52, it is elastically restored and can be engaged with the lower surface of the lower end corner portion 524 to reach the mounted state.

  In this mounted state, for example, the delivery from the upper lid 52 of the overcap 2 during delivery or transfer at a medical institution such as a hospital is reliably prevented. That is, even when the lower end opening edge of the cylindrical wall portion 212 of the overcap 2 collides with something and an impact force acts on the lower end opening edge from the bottom to the top during the transfer, the impact force is applied to each second claw portion. 23, the upward displacement of the overcap 2 is prevented. Therefore, an upward external force (external force in the opening direction) does not act on the upper lid 52 via each first claw portion 22, and the overcap 2 is secured to the upper lid 52 while maintaining the upper lid 52 in the closed state without fail. 52 can be held in a securely connected state.

  In addition, in the mounted state described above, not only the accessory of the overcap 2 is added to the vial 3, but also the overall shape is substantially cylindrical (see, for example, FIG. 1). Compared with the attached vial 3 (see, for example, the lower half of FIG. 4), the overall shape is completely different and the difference between them can be recognized at a glance. As a result, the vial 3 is attached or not attached. It is possible to reliably perform identification with a glance at whether or not the vial 3 is. For this reason, the vial 3 in which the injection is enclosed is provided to a medical institution such as a hospital without the overcap 2 attached, while the vial 3 in which the oral agent is enclosed is attached to the medical institution with the overcap attached. As a result, the doctor / nurse who administers to the patient at a medical institution or the patient himself / herself pays special attention to the fact that the vial 3 is not an injection but an oral preparation. It becomes possible to identify with a glance without a glance. This makes it possible to sufficiently or reliably prevent or avoid the occurrence of misuse such as misuse of an oral preparation as an injection or misuse of an injection as an oral preparation.

  When the oral agent enclosed in the vial 3 is administered to the patient in the medical institution or the like, or when the patient himself orally obtains the oral agent enclosed, the vial is obtained by squeezing the overcap 2. If it is removed from the side 3, the upper lid 52 can be removed while the upper cap 52 is opened and held in the overcap 2 as the overcap 2 is removed. That is, for example, if the overcap 2 is gripped and twisted in the direction intersecting the central axis X (the direction indicated by the two-dot chain line arrow in FIG. 6), in other words, the overcap 2 is gripped and the central axis X is On the other hand, when the first claw portion 22 is pulled out so as to be bent slightly, an operating force that the front end of the first claw portion 22 abuts against the lower end corner portion 524 of the upper lid 52 acts on the lower surface of the lower end corner portion 524, and as shown in FIG. Thus, the upper lid 52 is separated from the outer peripheral surface of the band seal ring 51, and the engagement with the inner peripheral edge 512 is released and the lid is opened. Then, by removing the overcap 2 as shown in FIG. 7, the upper lid 52 is completely separated from the banding ring 51 while being held in the overcap 2, and is opened. As shown in FIG. 8, the central region of the upper surface of the rubber plug 4 is exposed. As described above, the overcap 2 performs a role and function as a jig for opening the upper lid 52, and the opening operation is performed only by an operation of grasping the overcap 2 and twisting it. The function of reliably avoiding the operator's hand from touching the exposed portion of the band seal ring 51 or the rubber plug 4 or from touching other objects will be exhibited. Thereby, the opening operation of the upper lid 52 can be performed in a state where the exposed portions of the band seal ring 51 and the rubber plug 4 are reliably maintained in a clean hygienic state, and the above-described exposure accompanying the opening operation of the upper lid 52 is performed. Contamination of parts and the like can be surely avoided.

  An example of the operation of using the oral preparation in the vial 3 will be described based on the example of FIG. In the example of FIG. 8, the inner peripheral edge 512 of the band seal ring 51 is formed in an endless annular shape so as to constitute a pull ring, and a part of the inner peripheral edge 512 is connected to the outer peripheral portion via weakening lines 513 and 513 that can be easily broken. ing. For this reason, if the inner peripheral edge 512 is raised and then a part of the circumferential direction of the band sealing ring 51 is broken along the weakening lines 513 and 513 by, for example, putting a finger on the inner peripheral edge 512 and pushing it down, the band sealing ring Since 51 is removed, the rubber plug 4 can be pulled out to take out the internal oral agent, or the oral agent can be dissolved.

Second Embodiment
FIG. 9 shows a state before the overcap 6 according to the second embodiment of the present invention is attached to the sealed vial 3 which is a container with a cap, and FIG. 10 shows a state (attached state) attached to the vial 3. ). While this overcap 6 omits the second claw portions 23, 23,... From the overcap 2 of the first embodiment, an extension portion 614 for opening operation is additionally formed on the upper side. These points are the main differences from the first embodiment. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the detailed description thereof is omitted.

  The overcap 6 includes a cylindrical main body 61 having an open lower end and claw portions 62, 62,... Serving as a coupling means with the upper lid 52 constituting the flip cap 5. The cylindrical main body 61 includes a top wall portion 611 and a cylindrical wall portion 612 that extends downward from the outer periphery of the top wall portion 611. The cylindrical wall part 612 covers the upper side part 32 (see FIG. 3) side region of the main body part 31 of the sealed vial 3 and can extend upward from the top wall part 521 of the upper lid 52 by a predetermined dimension. The height (height) and an outer diameter that can change the region to at least substantially the same outer diameter as that of the main body 31 while covering the upper mouth 32 (see FIG. 3) side region of the main body 31 described above. Have. In short, the cylindrical main body 61 composed of the top wall portion 611 and the cylindrical wall portion 612 covers from the lower end opening to the upper lid 52 of the flip cap 5 from the upper lid 52 to the vicinity of the upper side of the main body portion 31 of the vial 3. And an outer surface shape that can change the overall shape including the vial 3 into a single cylindrical shape by setting it to the mounted state (see the state shown by the one-dot chain line in FIG. 9 or FIG. 10). . In addition, a step-like convex portion 613 that protrudes inward is formed at an upper position on the inner surface of the overcap 6 and at a position below the top wall portion 611 by a predetermined dimension. 52 is in contact with the upper surface of the projection 613 so that the upper part extends upward from the upper lid 52. The upper portion is an extension portion 614. A concave groove 615 extending in the circumferential direction is formed on the outer peripheral surface of the extension portion 614, whereby the outer peripheral edge of the top wall portion 611 protrudes in a bowl shape on the outer peripheral side. The edge 616 is formed. These concave groove 615 and convex edge 616 constitute an uneven portion.

  And, at a predetermined position in the vertical direction of the cylindrical wall portion 612, a predetermined number of claw portions 62, 62,... Are arranged at substantially equal intervals in the circumferential direction. An opening window 617 is formed so as to surround 62 and penetrate inside and outside. Each claw part 62 protrudes inward and obliquely upward to an inner position (a position on the central axis X side) than the outer diameter position of the lower end corner part 524 of the peripheral edge part 522 of the upper lid 52. Similar to the first claw portion 22 of the embodiment, it is formed to be engageable with the lower surface of the lower end corner portion 524 in the mounted state. In the mounted state, the projections 613 come into contact with the upper surface of the upper lid 52 in a state where each claw portion 62 is engaged with the lower surface of the lower end corner portion 524 of the upper lid 52, and the upper lid 52 is brought into contact with the projection 613 and each nail. The part 62 is sandwiched from the upper and lower sides (see FIG. 10).

  In the example shown in the figure, four claw portions 62 are arranged at respective positions (see FIG. 11) obtained by dividing the circumferential direction into four equal parts, but at least one is arranged as in the case of the first embodiment. It is sufficient that two or more are provided. Further, as shown in FIG. 11, each edge constituting each claw portion 62 and the opening window 617 is provided on the left and right sides of the separation line D with the convenience of die-cutting at the time of synthetic resin molding. For convenience of die cutting, it is set to extend in a direction such that it is at least parallel to each of the left and right sides, or preferably slightly expanded.

  In the overcap 6 described above, the lower end opening is opposed to the upper lid 52 in the same manner as in the first embodiment, with respect to the vial 3 (see FIG. 9) sealed with the rubber stopper 4 and the flip cap 5. Put it down from the state. When covered, the tip ends of the claws 62, 62,... Hit against the outer peripheral surface of the peripheral edge 522 of the upper lid 52 and are elastically deformed outward, and are elastically restored by climbing over the lower end corner 524 of the upper lid 52. The lever can be engaged with the lower surface of the lower end corner portion 524 to reach the mounted state.

  In this mounted state, as in the case of the first embodiment, not only the difference in whether or not an accessory called an overcap 6 is added to the vial 3, but also whether the overall shape is a tapered shape or a substantially circular shape. As if it is a columnar shape, it is possible to recognize the difference between the unmounted and mounted overcaps 6 at a glance with totally different overall shapes. As a result, special care is taken to distinguish whether the vial is an oral drug-filled vial (vial 3 with the overcap 6 mounted) or an injection-filled vial (unmounted vial 3). It becomes possible to identify with a glance without a glance. This makes it possible to sufficiently or reliably prevent or avoid the occurrence of misuse such as misuse of an oral preparation as an injection or misuse of an injection as an oral preparation.

  And when using the accommodation (oral preparation) of the vial 3 to which the overcap 6 is attached, if the overcap 6 is removed from the vial 3 side by prying in the same manner as in the first embodiment, the overcap 6 At the same time, the upper lid 52 is opened, and the upper lid 52 can be removed while being held in the overcap 2. That is, when the overcap 6 is gripped and twisted in the direction intersecting the central axis X, the operating force for twisting acts as a force in the opening direction from the tip of the claw portion 62 to the lower surface of the lower end corner portion 524 of the upper lid 52. Then, the upper lid 52 is separated from the outer peripheral surface of the band seal ring 51, and the engagement with the inner peripheral edge 512 (see FIG. 6) is released and the lid is opened. That is, the overcap 6 performs a role and function as a jig for opening the upper lid 52 as in the first embodiment, and also provides an operator with an exposed portion of the band seal ring 51 and the rubber stopper 4. The function of reliably avoiding the touch of the hand or other objects will be demonstrated, and this ensures that the exposed portion of the band ring 51 and the rubber plug 4 is maintained in a clean and hygienic state. Thus, the opening operation of the upper lid 52 can be performed, and contamination of the exposed portion and the like accompanying the opening operation of the upper lid 52 can be surely avoided.

  Further, in the opening operation, the operator can hold the extending portion 614 to perform the opening operation (the above-described operation), and therefore, the portion (the extending portion 614) extending upward from the upper lid 52. ) Can be transmitted to the lower end corner 524 based on this principle, and the lid opening operation can be easily performed with a relatively light operation force. In addition, since the extending portion 614 has concave and convex outer surface shapes such as the concave groove 615 and the convex edge 616, it is easy to apply an operating force, and it can be reliably gripped, so that the operation can be performed reliably.

  FIG. 12 shows an overcap 6a according to another aspect of the second embodiment. The overcap 6a is obtained by extending the extended portion 614a further upward than the extended portion 614 of the overcap 6 described above. That is, the vertical length of the cylindrical wall portion 612a is made larger than that of the cylindrical wall portion 612 of the overcap 6 in FIG. 9, and the vertical width of the concave groove 615a is increased by that much. These concave and convex grooves 615a and convex edges 616 constitute an uneven portion. The length of the extending portion 614a in the vertical direction is set to, for example, about half of the overall size in the vertical direction, or from about half to about 1/3 or about 1/4. In this case, the operation force mitigating action based on the above lever principle can be further increased, and handling at the time of operation is facilitated by increasing the gripping allowance. Furthermore, the difference in the overall shape (particularly the overall height) between the unmounted state and the mounted state becomes more obvious, and the above-described identification function can be made more satisfactory.

<Third Embodiment>
