Press-through pack, sealing sheet for press-through pack, and preparation method of tablet

Abstract

A press-through pack and a sealing sheet for use in the same capable of easily taking out solid material such as tablet or the like contained storage recesses by only pushing action of fingers. The pack comprises an accommodation body ( 2 ) with plural storage recesses ( 2 a ) defined by sheet like portions ( 2 b ) for a containing solid material therein and sealing sheet ( 5 ). The sealing sheet ( 5 ) is made of such material that a recess ( 2 a ) in which solid material (T) contained, is partly ruptured without causing floating and peeling at the adhesion portion of the adhesive layer ( 4 ) and the sheet like portions ( 2 b ) when pushing the projecting portion ( 2 c ) of the outer side of the recess ( 2 a ) with fingers, whereby the solid material (T) contained in the recess ( 2 a ) is easily taken out and the sealing sheet is partially bonded to the accommodation body at sheet like portions ( 2 b ) in a manner that the whole parts of sealing sheet ( 5 ) is easily peeled off from the accommodation body.

1 . A press-through pack comprising; 
 an accommodation body ( 2 ) having plural storage recesses ( 2   a ) provided with sheet like portions ( 2   b ) therebetween, and    a sealing sheet ( 5 ) having a substrate ( 3 ) on which one surface side an adhesive layer ( 4 ) is formed, said accomodation body ( 2 ) being sealed tightly by said sealing sheet ( 5 ) in a manner that said adhesive layer ( 4 ) and said sheet like portions ( 2   b ) are bonded to each other, with a solid material (T) contained in each of said plural storage recesses ( 2   a ) wherein, 
 said sealing sheet ( 5 ) is made of such material that the part of said sealing sheet ( 5 ) responding to said recess ( 2   a ), a part in which a solid material (T) in contained, is partly ruptured without causing floating and peeling of adhesion portion between said adhesive layer ( 4 ) of said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 3 ) when pushing the projecting portion of the outer side of said recess ( 2   a ) with fingers, whereby said solid material (T) contained in said recess ( 2   a ) is taken out and wherein,  
 said sealing sheet ( 5 ) is further bonded to said sheet like portions ( 2   b ) of said accommodation body ( 2 ) in a manner that said sealing sheet ( 5 ) is easily peeled off from said accommodation body ( 2 ).  
   
     
     
         2 . The press-through pack as set forth in  claim 1 , wherein said solid material (T) is a dividable tablet.  
     
     
         3 . The press-through pack as set forth in  claim 1  or  2 , wherein the bonding strength between said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 2 ) is not less than 0.9N/15 mm width and not more than 3.1N/15 mm width in T peeling test executed at a peeling speed of 200 mm/min.  
     
     
         4 . The press-through pack as set forth in  claim 1  or  2 , wherein the bonding strength between said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 2 ) is not less than 4.2N/15 mm width and not more than 7.0N/15 mm width in T peeling test executed at a peeling speed of 100 mm/min.  
     
     
         5 . The press-through pack as-set forth in one of  claims 1  to  4 , wherein an adhesion lowering component is mixed for an adhesive component of an adhesive forming said adhesive layer ( 4 ).  
     
     
         6 . The press-through pack as set forth in one of  claims 1  to  5 , wherein said adhesive layer ( 4 ) is coated on one surface side of said sealing sheet ( 5 ) by a partial coating method.  
     
     
         7 . A sealing sheet ( 5 ) for a press-through pack in which a substrate ( 3 ) and an adhesive layer ( 4 ) formed on one surface of said substrate ( 3 ) are provided, said adhesive layer ( 4 ) being bonded to sheet like portions ( 2   b ) of an accommodation body ( 2 ) having plural storage recesses ( 2   a ) provided with sheet like portions ( 2   b ) therebetween, for tightly sealing the accommodation body ( 2 ) wherein, 
 said sealing sheet ( 5 ) is made of such material that the part of said sealing sheet ( 5 ) responding to said recess ( 2   a ), a part in which a solid material (T) is contained, is partly ruptured without causing floating and peeling of adhesion portion between said adhesive layer ( 4 ) of said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 2 ) when pushing the projecting portion of the outer side of said recess ( 2   a ) with fingers, whereby said solid material (T) contained in said recess ( 2   a ) is taken out and wherein,    said sealing sheet ( 5 ) is designed to be bonded to said sheet like portions ( 2   b ) of said accommodation body ( 2 ) in a manner that said sealing sheet ( 5 ) is easily peeled off from said accommodation body ( 2 ).    
     
     
         8 . The sealing sheet for the press-through pack as set forth in  claim 7 , wherein the bonding strength between said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 2 ) is adjusted not less than 0.9N/15 mm width and not more than 3.1N/15 mm width in T peeling test executed at a peeling speed of 200 mm/min.  
     
     
         9 . The sealing sheet for the press-through pack as set forth in  claim 7 , wherein the bonding strength between said sealing sheet ( 5 ) and said sheet like portion ( 2   b ) of said accommodation body ( 2 ) is adjusted not less than 4.2N/15 mm width and not more than 7.0N/15 mm width in T peeling test executed at a peeling speed of 100 mm/min.  
     
     
         10 . A taking-out method of tablets from a press-through pack wherein, 
 said press-through pack ( 1 ) of  claim 2  is placed on a flat plate,    all dividable tablets (T) contained in each storage recess ( 2   a ) of said accommodation body ( 2 ) of said press-throught pack ( 1 ) are divided by applying an equal force from upward of said press-through pack ( 1 ) placed on the plate by means of a flat plate, and    said sealing sheet ( 5 ) is peeled off said accommodation body ( 2 ) and all the divided tablets contained in each storage recess ( 2   a ) of said accommodation body ( 2 ) are obtained at one time.
