Multiple compartment medical container

Abstract

A multiple-chamber medical container comprising a container body 3 having two chambers 10 and 11 for storing medicaments and a partition seal 20 separating the chamber 10 from the chamber 11 , and an outlet 32 attached to the container body 3 for allowing the medicaments to be discharged from the chamber 11 , the partition seal 20 being openable so that the chambers 10 and 11 may communicate with each other at the time of use, wherein the container body 3 comprises a discharge-control seal 21 separating the chamber 11 from the outlet 32 and being openable at the time of use, and the force required to open the partition seal 20 is lower than that required to open the discharge-control seal 21.

1 . A multiple-chamber medical container comprising: 
 a container body having multiple chambers for storing medicaments and a partition seal separating the chambers from each other; and    an outlet attached to the container body for allowing the medicaments to be discharged from one of the chambers;    the partition seal being openable so that the chambers may communicate with each other at the time of use; and    the container body comprising a discharge-control seal that separates at least one chamber from the outlet and is openable at the time of use,    wherein the force required to open the partition seal is lower than that required to open the discharge-control seal.    
     
     
         2 . The multiple-chamber medical container according to  claim 1 , wherein 
 at least an innermost layer of the container body comprises a film prepared from a mixture of two or more kinds of thermoplastics having low miscibility with one anther and different melting points, the peripheral edge portion thereof being heat-sealed to form the container body in the shape of a bag;    the partition seal and the discharge-control seal being provided by heat-sealing the surfaces of the film of the container body that are facing each other; and    the discharge-control seal having a sealing strength which is lower than that of the peripheral edge portion of the container body and higher than that of the partition seal.    
     
     
         3 . The multiple-chamber medical container according to  claim 2 , wherein at least the innermost layer of the container body comprises a film prepared from a mixture of polyethylene and polypropylene or of polyethylene and cyclic olefin resin.  
     
     
         4 . The multiple-chamber medical container according to  claim 1 , wherein the partition seal is provided with at least one projecting part that is projecting toward the chamber.  
     
     
         5 . The multiple-chamber medical container according to  claim 1 , wherein the discharge-control seal is formed arcwise around the outlet.  
     
     
         6 . The multiple-chamber medical container according to  claim 1 , wherein the force required to open the discharge-control seal by pressing a disc having a diameter of 100 mm against the container body is 5-10 kg higher than that required to open the partition seal by pressing the disc.  
     
     
         7 . The multiple-chamber medical container according to  claim 1 , wherein at least a part of the partition seal has a narrower width than that of the discharge-control seal.  
     
     
         8 . A multiple-chamber medical container comprising: 
 a container body having multiple chambers for storing medicaments and a partition seal separating the chambers from each other; and    an outlet attached to the container body for allowing the medicaments to be discharged from one of the chambers;    the partition seal being openable so that the chambers may communicate with each other at the time of use; and    the container body comprising a discharge-control seal that separates at least one of the chambers from the outlet and is openable at the time of use;    wherein the force required to open the partition seal is equal to that required to open the discharge-control seal.    
     
     
         9 . The multiple-chamber medical container according to  claim 8 , wherein the discharge-control seal is formed arcwise around the outlet.  
     
     
         10 . The multiple-chamber medical container according to  claim 1 , wherein the discharge-control seal is formed arcwise around the outlet in the proximity thereof and the partition seal is formed arcwise around the discharge-control seal at an interval required to form the chambers.  
     
     
         11 . The multiple-chamber medical container according to  claim 8 , wherein the discharge-control seal is formed arcwise around the outlet in the proximity thereof and the partition seal is formed arcwise around the discharge-control seal at an interval required to provide the chambers.  
     
     
         12 . A multiple-chamber medical container comprising: 
 at least one inner container for storing a medicament that is openable by increasing the internal pressure thereof;    an outer container containing the inner container and comprising a medicament chamber for storing a medicament on the outside of the inner container;    an outlet connected to the outer container; and    a discharge-control seal separating the medicament chamber of the outer container from the outlet;    wherein a liquid medicament is contained in at least the outer or inner container and the force required to open the discharge-control seal is higher than that required to open the inner container.    
     
     
         13 . The multiple-chamber medical container according to  claim 12 , wherein the force required to open the inner container by pressing a disc having a diameter of 100 mm is 5-10 kg lower than that required to open the discharge-control seal by pressing the disc against the outer container.  
     
     
         14 . The multiple-chamber medical container according to  claim 12 , wherein the inner container comprises a belt-shaped seal that is openable by increasing the internal pressure thereof and at least a part of the seal has a narrower width than that of the discharge-control seal.  
     
     
         15 . The multiple-chamber medical container according to  claim 12 , wherein the discharge-control seal is formed arcwise around the outlet.  
     
     
         16 . A multiple-chamber medical container comprising: 
 multiple inner containers that are openable by increasing the internal pressure thereof;    an outer container containing the multiple inner containers; and    an outlet connected to the outer container,    wherein a liquid medicament is contained in at least one of the inner containers.
