Description

  The present invention relates to a drug container with a lock lid provided with a lid that can be locked when in use.

  A container containing a fragrance, a deodorant, a deodorant and the like is generally used so as to cover an opening of a container body with a lid provided with a volatilization opening. However, since the lid is normally detachably provided, an unexpected situation may occur in which a child or an elderly person accidentally removes the lid and spills or eats the medicine.

  In order to cope with this, a plurality of convex portions or concave portions are provided on the side wall of the container body, and a lid body with a volatilization opening is locked to the inner lid to make it difficult to remove the inner lid from the container body. Has been proposed (for example, Patent Document 1). In this container, an inner lid with a volatilization opening is provided below the container opening, and the container opening is covered with an airtight sheet such as an aluminum foil to prevent volatilization of the drug before use. When the inner lid with a volatilization port is placed in the container main body in this way, the container opening is closed with an airtight sheet, and a three-layer structure is further covered with an outer lid with a volatilization port for protection of the sheet, The structure becomes complicated, and it takes time to manufacture. In addition, since the volatilization opening is provided in the inner lid, the opening area is limited, and depending on the drug, a sufficient volatilization effect may not be obtained.

  On the other hand, many types of drug containers are used in which the opening surface of the container body is hermetically closed with an inner lid, and an outer lid with a volatilization port is covered from above. In this case, a double structure of an inner lid and an outer lid is sufficient, and the structure is simple and the manufacture is easy. In addition, the opening area of the volatilization opening is easy to take. In this case as well, it is desirable to make it difficult to remove the outer lid in order to solve the above-mentioned problems associated with the removal. For example, the fragrance container described in Patent Document 2 is provided with a claw portion projecting inwardly on the fitting inner peripheral surface of the cover (lid), and a surface inclined in the circumferential direction on the fitting outer peripheral surface of the container body. And a recess is formed in the upper part of the inclined surface, and a plurality of protruding engaging portions are provided in the middle of the inclined surface. When the cover is attached to the container main body, when the cover is rotated in the circumferential direction, the claw portion rides on the inclined surface and engages with the concave portion, and the state is maintained. Further, when the container body swells with the organic solvent contained in the contents, the claw portion engages with the engaging portion in the middle of the inclined surface and maintains the state.

  However, this fragrance container is used by removing the cover once at the start of use, removing the cap from the mouth of the container body, and then attaching the cover again. Accordingly, the engagement between the claw portion and the concave portion or the engaging portion is merely held to such an extent that it can be released by the user. In this composition, there is still a possibility that a child or an elderly person accidentally removes the lid and causes an unexpected situation.

JP 2002-173186 A JP-A-11-262518

  The present invention solves the above-described problems of the prior art, and is a container of a type in which the opening of the container body is sealed with an inner lid and covered with an outer lid with a volatilization port, and the outer lid can be removed to remove the inner lid. It is an object of the present invention to provide a drug container that can be made and the outer lid can be locked after the inner lid is removed.

  In order to achieve the above object, the present invention provides a container body having an opening in the upper part of the housing part, an inner lid that seals the opening of the container body, and an outer lid that is attached to the upper part of the container body. The container main body is provided with an outer surface coupling portion on the outer peripheral surface, and the inner lid is engaged from above with a surface member that closes the opening and an opening peripheral edge of the container main body. An engaging portion that can be joined together, and a thick wall portion extending upward from the engaging portion, and the outer lid is provided on a central wall having a volatilization opening and on a radially outer side of the central wall at the time of mounting. A flange portion that contacts the thick portion of the inner lid; and an annular wall that hangs down from the outer peripheral edge of the flange portion and has an inner surface coupling portion on the inner circumferential surface, the outer surface coupling portion and the inner surface coupling portion are A structure that engages by rotating in one circumferential direction with the outer lid placed on the container body. An inner piece and an outer peripheral surface of the container body and an inner peripheral surface of the annular wall of the outer lid are engaged by a rotation in the one direction so as to form a ratchet engagement that prevents the rotation in the reverse direction. External pieces are provided, respectively, and the inner piece and the outer piece are ratchet engagements when the container body and the outer lid are joined by the inner face coupling portion 26 and the outer face joining portion 12 with the inner lid removed. The present invention provides a drug container with a lock lid, which is provided at a matching position.

  Since the drug container with a lock lid according to the present invention has the above-described configuration, the engagement portion and the surface member open the opening portion by engaging the engagement portion of the inner lid with the opening peripheral portion of the container body. Can be sealed. The outer lid can be attached to the container body by engaging the inner surface coupling portion of the outer lid with the outer surface coupling portion of the container main body. At this time, since the flange part abuts on the thick part of the inner lid and further lowering of the outer lid is prevented, ratchet engagement by the inner and outer pieces of the container main body and the outer lid does not occur. Therefore, at the start of use of the container, the outer lid can be removed, and the inner lid can be removed to release the seal.

  Then, by attaching the outer lid to the container body again after removing the inner lid, the chemical component can be volatilized through the volatilization port. At the time of mounting, the outer lid can be lowered without being obstructed by the thick part of the inner lid. Thereby, the ratchet engagement by the internal piece and the external piece provided in each of the container main body and the outer lid is possible, and the ratchet engagement is generated by the rotation of the outer lid with respect to the container main body. This prevents the outer lid from rotating in the reverse direction. Therefore, after the start of use, it is possible to prevent the outer lid from being accidentally removed, thereby preventing a shortage of spilling or eating the medicine.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same or similar parts in the drawings are denoted by the same reference numerals and description thereof is partially omitted.

  1 to 3 show a container according to an embodiment of the present invention. FIG. 1 is a plan view, FIG. 2 is a front view, and FIG. 3 (a) is a longitudinal front view.

  This container contains a fragrance and volatilizes a fragrance component during use, and these drawings show a state in which the container body 10 is covered with an outer lid 20. FIG. 4 is an exploded vertical sectional view showing the container, in which the container body 10 and the outer lid 20 are separated and the inner lid 30 is taken out from the container body 10. 5 (a), 6 (a), and 7 are a perspective view of the container body 10 as viewed from above, a perspective view of the outer lid 20 as viewed from below, and an inner lid 30 as viewed from below. It is a perspective view.

  The container body 10 has a cylindrical shape with the lower end closed, and has an opening 11 at the top. A male screw is provided on the outer peripheral surface of the container body 10 in the vicinity of the opening 11, and the male screw forms an outer surface coupling portion 12 for engagement with the outer lid 20. Immediately below the outer surface coupling portion 12, an inner piece 13 for making a ratchet engagement described below is provided. In this embodiment, the internal pieces 13 are provided at four locations that are equally spaced in the circumferential direction, and two locations appear in the figure. However, the number and arrangement are not limited to this. Further, a projecting edge 14 projecting in a circular shape is provided immediately below the inner piece 13. A large number of granular gel drugs P are accommodated in the container body 10.

  The outer lid 20 includes a central wall 21 having a volatilization port 22, a flange portion 23 extending radially outward from the central wall, and an annular wall 25 depending from the outer peripheral edge of the flange portion. The annular wall 25 has a short cylindrical shape, and a female screw that is threadedly engaged with a male screw that is the outer surface coupling portion 12 of the container body 10 is provided at the upper portion of the inner surface thereof, and the female screw forms an inner surface coupling portion 26. A number of external pieces 27 for ratchet engagement with the internal piece 13 of the container body 10 are provided immediately below the inner surface coupling portion 26. An annular auxiliary wall 24 hangs from the inner peripheral edge of the flange portion 23. The volatilization port 22 is formed by a large number of small holes of a size that does not allow fingers to enter, and is regularly arranged with design. The shape and arrangement of these small holes can be appropriately determined.

  The inner lid 30 includes a surface member 31 that closes the opening 11 of the container main body 10 and an engagement portion 32 that can engage with the peripheral edge of the opening in the container main body from above. The engaging portion 32 is formed by connecting the inner end wall 35 and the outer end wall 36 that can be respectively fitted to the inner surface 15 and the outer surface 16 of the peripheral edge of the opening in the container body 10 and the upper ends of the inner end wall and the outer end wall. And a thick-walled portion 37 extending to the top, and the cross section has an inverted U-shape. The inner lid 30 further includes a pulling ring 38 for hooking a finger when the inner lid 30 is removed from the container body 10. The pull ring 38 is coupled to the surface member 31 via the leg portion 39.

  In this embodiment, a structure for reliably holding the engagement state between the inner lid 30 and the container body 10 is provided. That is, as shown in FIG. 3B, the container body 10 is provided with a shallow groove 162 so as to form an annular convex portion 161 at the tip of the outer surface 16, and the inner lid 30 has an outer end wall. A shallow groove 362 is also provided on the inner surface of 36 so as to form an annular projection 361 at the tip. When the inner lid 30 is attached to the container main body 10, the convex portion 361 of the inner lid 30 and the convex portion 161 of the container main body 10 are engaged with the groove 162 of the container main body 10 and the groove 362 of the inner lid 30, respectively. Thus, the engaged state is reliably maintained. Since this engagement is performed based on the elastic deformation of both members, by pulling the pull ring 38, the engagement can be released and the inner lid 30 can be removed.

  When the inner lid 30 and the outer lid 20 are attached to the container body 10, the respective parts are positioned as follows. When the inner lid 30 is fitted to the container main body 10, the inner end wall 35 and the outer end wall 36 of the engaging portion 32 are fitted to the inner surface 15 and the outer surface 16 of the opening peripheral edge of the container main body 10, respectively, and the thick portion The lower surface of 37 abuts on the annular upper end surface 17 of the container body 10. When the outer lid 20 is covered from above, and the female screw of the inner surface coupling portion 26 is screwed into the male screw of the outer surface coupling portion 12 of the container body 10, the outer lid 20 descends relative to the container body 10, and the flange The lower surface of the portion 23 comes into contact with the upper surface of the thick portion 37 of the inner lid 30 and the descent stops. Therefore, a firm fastening can be obtained by tightly engaging the female screw and the male screw of the outer surface coupling portion 12 and the inner surface coupling portion 26 with the lower surface of the flange portion 23 in contact with the upper surface of the thick portion 37. . In this state, the outer piece 27 of the outer lid 20 is located higher than the inner piece 13 of the container body 10 and is not engaged. The auxiliary wall 24 of the outer lid 20 presses the inner end wall 35 of the inner lid 30 from the inside and presses it against the peripheral edge of the opening of the container body 10, thereby enhancing the sealing performance of the inner lid 30. In addition, when the airtightness of the inner lid 30 is sufficiently ensured, the auxiliary wall 24 can be omitted.

  When a medicine is stored in a container and distributed and sold as an aroma (or deodorant, deodorizing) instrument, the inner lid 30 and the outer lid 20 are mounted in a state where the medicine is contained in the container body 10. The drug is preferably an integral lump or a plurality of granular gels from the viewpoint of preventing spillage from the container, but can also be liquid or viscous fluid or powder. Since the opening part 11 of the container main body 10 is sealed with the inner lid 30, the chemical | medical agent in a container is prevented from volatilizing out of a container until use.

  The container containing the medicine is operated as follows at the start of use. First, the outer lid 20 is rotated in a direction opposite to that when the outer lid 20 is mounted, and the internal thread of the inner surface coupling portion 26 and the external thread of the outer surface coupling portion 12 of the container body 10 are unscrewed and removed from the container body 10. Next, the inner lid 30 is removed from the container body 10 by pulling the pull ring 38. Then, the outer lid 20 is rotated again in the mounting direction, and the female screw of the inner surface coupling portion 26 is screwed with the male screw of the outer surface coupling portion 12 of the container body 10. At this time, since the inner lid 30 is removed, the outer lid 20 flange portion 23 is lowered until it comes into contact with the upper end surface 17 of the container body 10 without being obstructed by the thick portion 37 of the inner lid 30. This state is shown in FIG.

  The outer piece 27 of the container body 10 and the inner piece 13 of the outer lid 20 are close to each other when the outer lid 20 is lowered and becomes lower than the position where the flange portion 23 is in contact with the thick portion 37. When the flange portion 23 starts to engage from this point and descends until the flange portion 23 comes into contact with the upper end surface 17 of the container body 10, the entirety or substantially the whole portion is engaged.

  The shapes of the inner piece 13 and the outer piece 27 are determined as follows. That is, as shown in FIGS. 5A and 5B, the inner piece 13 of the container body 10 is inclined so that the height (radial dimension) of the convex shape increases in the direction Rg in which the outer lid 20 is rotated when being mounted. The shape includes a surface 131 and an upstanding surface 132 extending substantially perpendicularly (in the radial direction) from the tip of the inclined surface 131 to the outer peripheral surface of the container body 10. Further, as shown in FIGS. 6 (a) and 6 (b), the outer piece 27 is formed by a tongue piece extending so as to protrude radially inward from the inner surface of the annular wall 25 of the outer lid 20, The tongue piece is inclined so that the protruding height is lowered in the direction Rg in which the outer lid 20 is rotated with respect to the container body 10 when mounted, and the lower end is coupled to the inner surface of the annular wall 25, The end is a free end. FIG. 6B shows a state in which the horizontal cross section of the annular wall 25 of the outer lid 20 is viewed from above.

  Therefore, when the outer lid 20 is rotated in the mounting direction with respect to the container main body 10 in a state where the inner piece 13 and the outer piece 27 can be engaged, the outer piece 27 in contact with the inclined surface 131 of the inner piece 13 has an inclination angle. The inner piece 13 can be overcome so as to make it smaller, and rotation can be continued. On the other hand, when the outer lid 20 is rotated in the opposite direction with respect to the container body 10, the tip end portion of the outer piece 27 comes into contact with the standing surface 132 of the inner piece 13. Even if a rotational force is applied in this contact state, no force acts in the direction of reducing the inclination angle of the external piece 27. Therefore, further rotation from the contact state is prevented. In this way, a ratchet engagement is obtained that can only rotate in one direction and is prevented from rotating in the opposite direction.

  Since the outer piece 27 of the container body 10 and the inner piece 13 of the outer lid 20 are formed as described above, the outer lid 20 is rotated in the mounting direction with respect to the container body 10 with the inner lid 30 removed. Then, with the outer piece 27 and the inner piece 13 starting to engage, rotation in the reverse direction is suppressed by the ratchet engagement, and the two pieces are engaged at the full height, almost the full height, or a sufficiently close height. As a result, a locked state is obtained in which rotation in the reverse direction is reliably prevented.

  Thus, in order to reliably obtain the locked state by the engagement between the outer piece 27 and the inner piece 13 after the inner lid 30 is removed, the height h of the thick portion 37 is desirably 1 to 5 mm. In this embodiment, it is 3 mm. If this height is lower than the above lower limit, the amount of engagement between the outer piece 27 and the inner piece 13 is reduced, and a sufficient rotation preventing force may not be obtained. Moreover, when this height is higher than the said upper limit, the fall amount at the time of mounting | wearing the outer cover 20 after the inner cover 30 removal will become large, and operation will become difficult. From this viewpoint, the height h of the thick portion 37 is more preferably 2 to 4 mm.

  Therefore, according to this container, at the start of use, after removing the outer lid 20 and removing the inner lid 30 from the container body 10, the outer lid 20 is placed on the container body 10 and rotated in the mounting direction. When the piece 27 is engaged, the outer lid 20 cannot be removed from the container body 10. As a result, there is an effect that there is no fear that the outer lid 20 is accidentally removed and the stored medicine is spilled or accidentally eaten. Further, since the outer lid is prevented from rotating in the loosening direction, it is possible to reliably prevent the outer lid from being detached from the container body even when used in a place such as in an automobile where vibration is received.

  The outer surface coupling portion of the container main body and the inner surface coupling portion of the outer lid can have various structures that are engaged by rotating in one circumferential direction with the outer lid placed on the container main body. FIG. 9 is an exploded view showing an example of a container having another coupling structure. The figure shows the container body 10, the inner lid 30, and the outer lid 20, and only the outer lid 20 is shown in cross section. In this embodiment, the forms of the outer surface coupling portion 12a of the container body 10 and the inner surface coupling portion 26a of the outer lid 20 are different from those of the previous embodiment, and the other structures are the same as those of the previous embodiment.

  The outer surface coupling portion 12 a is formed as an engagement groove 120 formed on the outer peripheral surface of the container body 10. The engagement groove 120 includes an axial groove 121 extending from the upper end of the container body 10 in the direction of the central axis, a circumferential groove 122 extending from the lower end of the container body 10 in the circumferential direction, and the same circumference from the tip of the circumferential groove. And a lower groove 123 extending downward in the direction of the direction. The inner surface coupling portion 26 a is formed by an engagement protrusion 261 provided on the inner surface of the annular wall 25 of the outer lid 20.

  The engagement groove 120 and the engagement protrusion 261 are provided as follows to form a bayonet type connection. In a state where the inner lid 30 is mounted on the container body 10, the engagement protrusion 261 enters the axial groove 121 when the outer lid 20 is moved down over the container body 10, and from this state, the outer lid 20 is moved to one side. , The engaging protrusion 261 enters the circumferential groove 122. In this case, by setting the width of the circumferential groove 122 to be a size that can closely receive the engaging protrusion 261, the engaging protrusion 261 can not easily come out of the circumferential groove 122, so that the outer lid 20 is attached to the container body 10. On the other hand, it can be firmly fastened.

  On the other hand, in a state where the inner lid 30 is removed from the container main body 10, the outer lid 20 is put on the container main body 10, the engaging protrusion 261 enters the axial groove 121, and the outer lid 20 is rotated to engage the engagement protrusion. When the portion 261 enters the circumferential groove 122 and the outer lid 20 is further rotated in the same direction, the engaging protrusion 261 enters the lower groove 123 with the lowering of the outer lid 20. The entry into the lower groove 123 is possible when the outer lid 20 moves down without being obstructed by the thick portion 37 of the inner lid 30. Due to the lowering of the outer lid 20, the inner piece 13 of the container body 10 and the outer piece 27 of the outer lid 20 have a height capable of being engaged, and are engaged with each other by the rotation of the outer lid 20 in the circumferential direction. Thus, ratchet engagement occurs and rotation is prevented in the reverse direction as in the previous embodiment. As a result, accidental removal of the outer lid 20 is prevented. In order to secure the rotation range of the outer lid 20 in the circumferential direction, the lower groove 123, as shown by a one-dot chain line in FIG. May be formed.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, in the embodiment shown in FIGS. 1 to 8, the arrangement of the ratchet engagement structure can be reversed, and the inner piece 13 can be provided on the outer lid 20 and the outer piece 27 can be provided on the container body 10. Alternatively, both of them may be mixed and provided on the outer lid 20 and the container body 10 respectively.

  In the embodiment shown in FIG. 9, it is possible to provide the engaging groove 120 in the outer lid 20 and the engaging protrusion 261 in the container body 10 by reversing the arrangement of the bayonet type coupling structure. Alternatively, both of them may be mixed and provided on the outer lid 20 and the container body 10 respectively.
