Two-drug pharmaceutical container

Abstract

The present invention provides a two-drug pharmaceutical container in which it is possible to remove the cap without loosening its nozzle cap and container main body when its cap is turned in the opening direction at the time of administering eye drops or the like. The container in which, on an outer surface of a nozzle section 12 of a container main body 1, a small diameter annular section 14 on which upper stage external ratchet teeth 16 are formed and a large diameter annular section 15 on which lower stage external ratchet teeth 17 are formed are provided, and in a nozzle cap 2 whose body section 22 and sealing ring part 23 are jointed together so as to be breakable, upper stage internal ratchet teeth 28 and lower stage internal ratchet teeth 29 are provided on the inner surfaces of the body section 22 and the sealing ring part 23, and the container is configured so that only the lower stage internal and external ratchet teeth 17 and 29 engage with each other to prevent turning in the opening direction in a closed state before use, and moreover, the upper stage internal and external ratchet teeth 16 and 28 engage with each other to prevent turning in the opening direction in a state in which the container main body is closed with the nozzle cap 2 without the sealing ring part 23.

1 . A two-drug pharmaceutical container comprising;
 a container main body which is filled with a first ingredient, and provided with a male screw on an outer circumferential surface of a nozzle section;   a nozzle cap which has a body section provided with a female screw screwed together with the male screw on an inner circumferential surface of its tube body, a head section including a medicinal solution extracting orifice communicated with an inside of the body section, and a sealing ring part provided via a plurality of breakable joining sections which are provided along a circumferential direction on a lower edge of the body section; and   a cap screwed on so as to cover the head section of the nozzle cap, wherein   a small diameter annular section with an outer diameter larger than an outer diameter of the male screw of the nozzle section and a large diameter annular section, which is on the lower side of the small diameter annular section, with an outer diameter larger than the outer diameter of the small diameter annular section are provided at a lower portion of the nozzle section of the container main body, and upper stage external ratchet teeth and lower stage external ratchet teeth are respectively provided on an outer circumferential surface of the small diameter annular section and an outer circumferential surface of the large diameter annular section, and on the other hand, upper stage internal ratchet teeth and lower stage internal ratchet teeth are respectively provided on an inner circumferential surface of a lower portion of the body section and an inner circumferential surface of the sealing ring part in the components of the nozzle cap,   and in a closed state in which the female screw of the body section of the nozzle cap is screwed together with the male screw of the container main body to be turned up to a position at which the container main body is closed, although the upper stage internal ratchet teeth and the upper stage external ratchet teeth do not engage with each other, the lower stage internal ratchet teeth and the lower stage external ratchet teeth engage with each other to prevent turning in an opening direction, and moreover,   in a closed state in which the joining sections of the nozzle cap are broken to remove the sealing ring part from the container main body, and the female screw of the body section of the nozzle cap without the sealing ring part is screwed together with the male screw of the container main body to be turned up to the position at which the container main body is closed, the upper stage internal ratchet teeth and the upper stage external ratchet teeth engage with each other to prevent turning in the opening direction.   
     
     
         2 . The two-drug pharmaceutical container according to  claim 1 , wherein a downward protruding piece is provided on the lower edge of the body section and an upward protruding piece is provided so as to come close to the closing side in the circumferential direction from the downward protruding piece on an upper edge of the sealing ring part in the components of the nozzle cap, and the front part lower end of the downward protruding piece is extended downward from the rear part upper end of the upward protruding piece. 
     
     
         3 . The two-drug pharmaceutical container according to  claim 1 , the container is used for any purpose of eye drops, ear drops, and nose drops. 
     
     
         4 . A method for using the two-drug pharmaceutical container comprising the successive steps of:
 in use of the two-drug pharmaceutical container according to  claim 1 ,   operating the nozzle cap to turn in the opening direction to break the joining sections, and removing the nozzle cap without the sealing ring part and the sealing ring part from the container main body;   adding a second ingredient into the container main body and operating the nozzle cap to turn in the closing direction to close the container main body; and   operating the cap to turn in the opening direction to remove the cap from the nozzle cap, and discharging a medicinal solution containing the first ingredient and the second ingredient from the medicinal solution extracting orifice.   
     
     
         5 . The two-drug pharmaceutical container according to  claim 2 , the container is used for any purpose of eye drops, ear drops, and nose drops. 
     
     
         6 . A method for using the two-drug pharmaceutical container comprising the successive steps of:
 in use of the two-drug pharmaceutical container according to  claim 2 ,   operating the nozzle cap to turn in the opening direction to break the joining sections, and removing the nozzle cap without the sealing ring part and the sealing ring part from the container main body;   adding a second ingredient into the container main body and operating the nozzle cap to turn in the closing direction to close the container main body; and   operating the cap to turn in the opening direction to remove the cap from the nozzle cap, and discharging a medicinal solution containing the first ingredient and the second ingredient from the medicinal solution extracting orifice.   
     
     
         7 . A method for using the two-drug pharmaceutical container comprising the successive steps of:
 in use of the two-drug pharmaceutical container according to  claim 3 ,   operating the nozzle cap to turn in the opening direction to break the joining sections, and removing the nozzle cap without the sealing ring part and the sealing ring part from the container main body;   adding a second ingredient into the container main body and operating the nozzle cap to turn in the closing direction to close the container main body; and   operating the cap to turn in the opening direction to remove the cap from the nozzle cap, and discharging a medicinal solution containing the first ingredient and the second ingredient from the medicinal solution extracting orifice.
