Container

Abstract

A drug container with no need to peel a gas-barrier film or with no need to contain a desiccant, an oxygen absorbent or the like, in which the contents therein can be seen by the naked eyes. The container ( 10 ) comprises a front sheet ( 20 ) and a rear sheet ( 22 ), the front sheet ( 20 ) and the rear sheet ( 22 ) being fusion-bonded each other so as to form a space ( 14 ) therebetween, wherein the front sheet is constituted of a multilayered film having a linear-polyolefin layer as the outermost layer, wherein the rear sheet is constituted of a multilayered film having at least one selected from a group consisting of a metal foil, a vapor-deposited metal layer and a vapor-deposited inorganic layer, and wherein a transparent covering sheet ( 24 ) comprising a film having a vapor-deposited metal oxide layer is fusion-bonded to the front sheet so that the entire outer surface of at least a part of the front sheet which forms the space can be covered with the transparent covering sheet ( 24 ).

1 . A container comprising a front sheet and a rear sheet, the front sheet and the rear sheet being fusion-bonded each other so as to form a space therebetween,
 wherein the front sheet is constituted of a multilayered film having a linear-polyolefin layer as the outermost layer,   wherein the rear sheet is constituted of a multilayered film having at least one selected from a group consisting of a metal foil, a vapor-deposited metal layer and a vapor-deposited inorganic layer, and   wherein a transparent covering sheet comprising a film having a vapor-deposited metal oxide layer is fusion-bonded to the front sheet so that the entire outer surface of at least a part of the front sheet which forms the space can be covered with the transparent covering sheet.   
   
   
       2 . The container according to  claim 1 , wherein said metal oxide is at least one selected from a group consisting of silicon oxide and aluminum oxide. 
   
   
       3 . The container according to  claim 1 , wherein said film having a vapor-deposited metal oxide layer is at least one selected from a group consisting of a polyester film, a poly (vinyl alcohol) film, a polypropylene film, and a nylon film having a vapor-deposited metal oxide layer. 
   
   
       4 . The container according to  claim 1 , wherein the covering sheet is constituted of a multilayered film having a linear polyolefin film being laminated beneath said film having a vapor-deposited metal oxide layer. 
   
   
       5 . The container according to  claim 1 , wherein the covering sheet comprises a film having a plurality of said vapor-deposited metal oxide layer laminated. 
   
   
       6 . The container according to  claim 5 , wherein the covering sheet comprises a film having two vapor-deposited metal oxide layers laminated. 
   
   
       7 . The container according to  claim 1 , wherein said covering sheet has a steam permeability of 0.2 g/m 2  day or lower. 
   
   
       8 . The container according to  claim 1 , wherein said covering sheet has an oxygen permeability of 0.02 cc/m 2 ·day·atm or lower. 
   
   
       9 . The container according to  claim 1 , having a water increasing ratio (in case of storage at 40° C. and 75% RH for 6 months) of 0.5 wt % or less. 
   
   
       10 . The container according to  claim 1 , wherein a light transmittance of said film having a vapor-deposited metal oxide layer against light which wavelength is 450 nm ranges from 55 to 99%. 
   
   
       11 . The container according to  claim 1 , wherein the periphery of the covering sheet is fusion-bonded to the front sheet. 
   
   
       12 . The container according to  claim 1 , wherein the covering sheet is adjacent to the front sheet in a state where it contacts with the front sheet. 
   
   
       13 . The container according to  claim 1 , wherein the covering sheet is adjacent to the front sheet with a space interposed therebetween. 
   
   
       14 . The container according to  claim 1 , being used as a container for holding a drug. 
   
   
       15 . The container according to  claim 1 , being connected to another container through a weak seal part interposed therebetween. 
   
   
       16 . The container according to  claim 15 , wherein said another container holds a liquid agent, said another container and said container holding a powder drug are connected each other through a weak seal part interposed therebetween. 
   
   
       17 . The container according to  claim 2 , wherein said film having a vapor-deposited metal oxide layer is at least one selected from a group consisting of a polyester film, a poly (vinyl alcohol) film, a polypropylene film, and a nylon film having a vapor-deposited metal oxide layer. 
   
   
       18 . The container according to  claim 2 , wherein the covering sheet is constituted of a multilayered film having a linear polyolefin film being laminated beneath said film having a vapor-deposited metal oxide layer. 
   
   
       19 . The container according to  claim 2 , wherein the covering sheet comprises a film having a plurality of said vapor-deposited metal oxide layer laminated. 
   
   
       20 . The container according to  claim 2 , wherein said covering sheet has a steam permeability of 0.2 g/m 2 ·day or lower.
